Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, in embodiment shown in Fig. 7, reef base is bred in a kind of ocean that can be discrete, comprise main algal reef body 1, main fish shelter body 2, described main algal reef comprises open-topped algal reef net cage platform 3, the inflation floating foundation 4 be connected with algal reef net cage platform, described main fish shelter body is provided with some growth substrate 5 that feeds intake in advance for throwing in marine alga seedling, described Inflated floating basal part is provided with spool, described spool is wound with a main hoist cable 6, main hoist cable one end connects spool, the main hoist cable other end stretches out formation free end downwards, described free end connects main fish shelter body, described main fish shelter body is provided with some main body connecting rods 7, main body connecting rod lower end and main fish shelter body are fixed, main body connecting rod upper end by main erosion break bar 8 connect inflation floating foundation, described inflation floating foundation is provided with gas tube 9, described gas tube be provided with one stretch out sea fill exhaust joint 10, described gas tube is provided with stop valve, the described external sidewall of main fish shelter is provided with counterweight connecting ring edge 46, described counterweight connecting ring edge is provided with some splicings 47, described splicing lower end connects one and sinks to the bottom balancing weight 48, described algal reef net cage platform is provided with some breach, indentation, there is provided with vertical side plate 49, side plate leans against on algal reef net cage platform towards the side of algal reef net cage platform, side plate lower end and algal reef net cage table-hinges connect, side plate upper end is connected with algal reef net cage platform by erosion part.
For settling marine alga seedling in algal reef net cage platform, marine alga seedling also can be arranged within algal reef net cage platform together with cultivation base (as algae brick, Miao Ji etc.).Inflation in inflation floating foundation, for supporting main algal reef body, main fish shelter body is suspended in sea when just throwing in.If necessary, the main algal reef body initial stage also can be in more than sea.Main hoist cable is not tensioning at the beginning, can throw in some marine alga seedling in the growth substrate that feeds intake in advance.Sink to the bottom balancing weight, splicing for spacing inflation floating foundation, prevent drift distance of the present invention excessive.
Main erosion is broken, and bar can adopt metal, alloy is made, its in the seawater (relatively main algal reef body, main fish shelter body, main hoist cable, main body connecting rod etc. corrosion very slow structure) can comparatively fast corrode, thus erosion is disconnected over time.And main erosion bar erosion of breaking is had no progeny, main fish shelter body is no longer held by main body connecting rod, will sink, and it is outer and reach tensioning state that main hoist cable is fully stretched out spool, and main fish shelter body sinks, and main algal reef body is in below sea (close to sea).So input of the present invention can be divided into two megastages: main erosion break bar erosion disconnected before, main erosion bar erosion of breaking has no progeny.
When first megastage; all structures are all suspended near sea, and now, algal reef net cage platform, the in advance marine alga fed intake in all structures with (pre-cast is placed with) marine alga seedling such as growth substrate start growth; this period; major part marine alga is in suitable region of growth () on the sea near, can receive enough illumination again, grows than faster; and; in the place close to sea, fish are relatively few, are equivalent to carry out protection to a certain degree to marine alga seedling.After date when one section, marine alga has grown into certain degree, and now main fish shelter body can sink to locating.One of them main cause that main fish shelter body can sink is: in algal reef net cage platform, taking up room of marine alga becomes large gradually, be about to extend to outside algal reef net cage platform, if now main fish shelter body sinks, more space can be provided, and allow marine alga appropriateness sink, avoid top marine alga reach more than sea and depart from seawater.Main fish shelter body can set from the time just rendering to sinking, was controlled (without the need to very accurate, differ and there is no large impact a little time) by break erosion break time of bar of main erosion.The erosion break time can draw throwing in the corrosion rate in marine site seawater according to main erosion bar material of breaking, such as in the seawater of salinity 3.5%, the corrosion rate of plain cast iron is annual 0.15mm, if so marine alga needs the first vegetative period of the first quarter, then can arrange the break diameter of bar of main erosion is 0.03mm, after about first quarter, main erosion is broken, and bar erosion is disconnected lost efficacy.Certainly, in practical structures, also to consider that main erosion is broken the weight capacity (breaking the limit) of bar, such as, when main erosion break shank diameter be less than A value time, will be pulled off because bearing the lower pulling force of main fish shelter body, then in actual applications, will arrange the break diameter of bar of main erosion is that 0.03mm adds A value.Certainly, erosion break time and suitable metal, alloy material have a lot can be controlled, can select according to demand during manufacture, further, if need to control more accurately to lose the break time, the principle of galvanic corrosion can also be utilized arrange the disconnected bar structure of erosion, main erosion is such as allowed to break bar as anode, main body connecting rod selects suitable material as negative electrode, selects suitable main erosion to break bar material, allows anode (main erosion break bar) corrosion fracture after a certain time.
When second megastage, the main erosion bar that breaks is disconnected, and main fish shelter body sinks, and main algal reef body is in below sea (close to sea).And the marine alga of initial stage good growth in the growth substrate that feeds intake in advance is because be attached in the structure such as the growth substrate that feeds intake in advance, main fish shelter body, is also driven sinking together, thus be can be used as the bait at initial stage, had great contribution for poly-fish.And, marine alga seedling or the spore of the growth of applicable shallow sea area only can not be thrown in the growth substrate that feeds intake in advance when reality is thrown in, also can throw in some be suitable for seabed place, the place of the present invention degree of depth growth marine alga seedling or spore (such as input place seabed depth is 30 meters, then can pre-cast some to be suitable under sea the marine alga seedling of 30 meters of growths, and the marine alga of the lower growth in these suitable seas, then can not consider to have gathered, only need the effect being considered as fish food), so, the good marine alga of primary growth is as early food, and the marine alga of the lower growth in suitable sea well can grow after sinking, as " feed supplement ".Above-mentioned such feeding mode, feeds intake precisely, can ensure that bait is on fish shelter, near fish shelter, and waste is few, and is disposable input, without the need to too much subsequent operation.The present invention only by once throwing in, just need can realize main algal reef body, two reefs of main fish shelter body is thrown in, and are convenient and efficient.Side plate combines (and blocking breach) with algal reef net cage platform at the beginning, after marine alga amount reproduction in algal reef net cage platform, erosion part erosion disconnected (principle with main erosion break bar), Joint failure, side plate is along hinged end (outwards) overturning, and form larger marine alga and freely breed space, the side plate after outside overturning can carry out bracketing to local marine alga, and can attaching structure be provided, effectively benefit marine alga propagation.
Described main fish shelter body is provided with some abduction fish shelter bodies 11, described abduction fish shelter body comprises spherical fish shelter net cage 12, the abduction bar 13 that can rotate relative to main fish shelter body, the upper end of described abduction bar connects spherical fish shelter net cage, lower end and the main fish shelter body of abduction bar are hinged, described abduction bar is provided with for stopping the limit body that abduction bar rotates in main fish shelter body, described main fish shelter body is provided with the outrigger edge 14 for the outer exhibition bar of frame, when abduction bar turns to horizontal level towards main fish shelter is external, abduction bridge leans against on outrigger edge, described abduction fish shelter body is provided with the gathering line of tensioning, the one end of drawing line in connects main algal reef body, the other end drawing line in connects abduction fish shelter body.When first megastage, feed intake growth substrate in advance, the seaweed growth at the places such as algal reef net cage platform, during seaweed growth, the structure of meeting finding nearby is adhered to, now spherical fish shelter net cage is drawn in line and is held gathering, relatively near the growth substrate that feeds intake in advance, be beneficial to the attachment of marine alga, also can prevent the epitaxial growth of part marine alga excessively (epitaxial growth excessive marine alga easily depart from main fish shelter body) depart from inflation floating foundation at main fish shelter body, when starting to sink, due to the cause of gravity, gathering line is pulled off, thus, abduction fish shelter body starts outside upset, abduction bar turns up to level, frame is on outrigger edge, whole fish reef structure spreads out, achieve automatic expansion, space availability ratio effectively promotes, and multiple abduction fish shelter body can form complicated small-sized reef group together with main fish shelter body, be beneficial to and improve poly-fish effect and protected effect, relate generally to area and become large, so stability is also higher.
Described abduction fish shelter body is provided with many temporary guys 15, and the two ends of described temporary guy connect Inflated floating basal part, spherical fish shelter net cage respectively, and the angle be located between any two temporary guys on an abduction fish shelter body is greater than 15 degree.The effect of temporary guy can assist pulling abduction fish shelter body to be in rounding state first; second many lines can be provided; form similar netted structure; marine alga on main fish shelter body is protected; marine alga too much can not be eaten by fish (especially large fish) at early growth period; maintain good growth, so that the main fish shelter body afterwards for sinking provides sufficient poly-fish bait.
Described limit body comprises the fence 16 of some annulars, parallel to each other between each fence, and the lateral border of each fence all contacts all abduction bars, and described abduction bar is in outside all fences.Fence can directly as limit body; block the inside upset trend of abduction fish shelter body; effective protection can be formed simultaneously; coordinate " the temporary guy net " of top, coordinate the abduction bar in outside; form protection complete from top to bottom, fully ensure that " bait " (marine alga) has good growing environment in the early stage.
Described inflation floating foundation sidewall is provided with some expansion shape connecting rods 17, described expansion shape connecting rod is provided with horizontal expansion algal reef 18, described horizontal expansion algal reef comprises horizontal expansion net cage 19, be located at the horizontal expansion reef base 20 of horizontal expansion net cage bottom, described horizontal expansion reef base can along expansion shape rod slide, described expansion shape connecting rod with become 15 to 75 between horizontal plane and spend angle, expand one end of shape connecting rod contiguous inflation floating foundation higher than expanding shape connecting rod one end away from inflation floating foundation, described horizontal expansion algal reef is provided with for preventing horizontal expansion reef base from departing from the tie-down cable 21 expanding shape connecting rod, described tie-down cable two ends connect horizontal expansion reef base respectively, inflation floating foundation, described horizontal expansion reef base, connected by the lateral erosion bar 22 that breaks between inflation floating foundation.Horizontal expansion algal reef can expand algal reef cultivation scope further, provides more marine alga to breed space in once throwing in.When lateral erosion bar erosion of breaking has no progeny that (principle to be broken bar with main erosion, the erosion break time is controlled), because gravity, horizontal expansion algal reef can move (to the external slid underneath of main algal reef) outside expansion shape connecting rod, slide out to relatively away from the position of main algal reef body, all for the marine alga in algal reef net cage platform provides enough growth wider spaces on horizontal space, longitudinal space, avoid marine alga close folded.Horizontal expansion algal reef is except transverse shifting, also move down, this has reason, because in certain region, too much marine alga cannot well grow, but marine alga is lacked and to waste propagation space, so, after a certain time, horizontal expansion algal reef location-appropriate is traversing, lower, the marine alga on algal reef net cage platform is allowed to continue growth fully fast, and the marine alga growing way appropriateness on horizontal expansion algal reef slows down (obtaining the factors such as illumination tails off relatively), thus, ensure that the growing way of whole seaweed growth group promotes in the reasonable scope, more effectively utilize seaweed growth space, avoid the problems such as the close folded part marine alga necrosis caused of marine alga.
