Inveni'or ILmu-muD w MMMM+ We UNDERWATER cownncroa The present invention concerns a remote-controlled underwater connector, capable on the one hand of attaching itself to a submerged object and bringing it to the surface, and on the other hand of providing a connection with this object, after attaching itself to it, through a number of hydraulic or electrical lines, in order to transmit impulses, control signals or driving force to it.
At the present stage of technical progress, most existing underwater connectors are produced for the oil industry, and therefore contain a large passage in the center for drilling or production tools. Where they also allow hydraulic lines to be connected, the space taken up by these makes the outside diameter of the connector even larger, or necessitates adding another section to the main connector.
In the connector involved in the invention, the system for the connection of the hydraulic or electrical lines is incorporated in the center of the appliance, thus providing a light, compact and at the same time sturdy unit.
This connector can be used in all cases where it is necessary to bring up or submerge large objects containing remote-controlled instruments, and in particular it can be used to install and raise submerged installations made up of modules that can be-disconnected and handled separately.
The connector involved in the invention, consisting of a mobile cylindrical cup which fits easily on to an inner component which also revolves, the cup being connected to a cable by a threaded section and the other unit being attached to the object to be submerged or raised, is characterized in that bolting devices forming part of the cup fit into slots in the inner component when the edge of the said cup is resting on the upper edge of the inner component and the two components are positioned correctly in relation to each other, the bolting devices being pushed into the slots by the operation of a jack which causes a bellcrank lever to pivot on a fixed axis, the upper end of the said jack being connected to another bellcrank lever which can pivot on a second fixed axis, and which, when at rest, is held against a block by means of a spring.
According to another characteristic of the invention, the bolt can be withdrawn from the slot without using the jack, in the event of the jack failing to work, for instance, by exerting tension on a rod attached to the upper bellcrank lever, in such a way as to free the cup.
The invention will be clearer from the description below, and the single FIGURE accompanying it.
This FIGURE gives a cross-sectional view of the connector.
A cylindrical mobile cup 33 fits easily on to a revolving inner component 45. A threaded section 23 allows the cup to be attached to a handling cable. The inner component has devices 41 to attach on to the object to be moved.
Bolts 6 on the cup can be fitted into slots in the inner component, when the rim 46 of the cup rests on the upper edge 47 of the inner component, and the two components 33 and 4 are correctly positioned in relation to each other.
The bolts are fitted into the slots by means of the jack 9, the action of which causes a bellcrank lever 7 to pivot on the fixed axis 3.
The upper end ll2 of the jack has the characteristic of being connected to a second bellcrank lever 14, which can pivot on a fixed axis l3, but which is normally held against a thrust block 43 by a spring it).
The bolt 6 can be withdrawn from the slot 5 without using the jack 9, in the event of the jack failing to work, for instance, by pulling a rod l l, attached to the lever.
The hydraulic or electrical lines carrying the signals or driving force to be transmitted to the object are contained in underwater pipes or cables descending from the surface of the sea along with the cup.
They enter the cup through apertures such as 20, by means of flexible tubes such as 17, ending at a plate 44 which contains the top halves 2 of hydraulic or electrical connectors.
The bottom halves of these connectors l are located on the component 45.
The plate 44 can be moved up or down by means of two cams 35. This plate forms the base of a truncated conical sleeve 39, which protects the flexible tubes 17, and is joined by rods 40 to a mechanism allowing it a slight upward or downward movement.
This mechanism consists of two cylinders 30 and 36, with two cams 35 at the extremities in contact.
When one cylinder rotates in relation to the other, they are pushed apart vertically, while reverse rotation brings them closer together, until the two cams fit together completely.
This rotation is obtained by keeping the cylinder 36 in a fixed position by means of the lug 19, which slides along a vertical groove in the component 13, and by turning the cylinder 30 by means of the lever 34, which is attached to it, and which is operated by the jack 32.
The other end of this jack is attached to the cup 33 by the component 311.
A set of elastic washers 22, interposed between a coupling 24 fixed rigidly to the cylinder 30 and a nut attached to the rod 24, which is fixed to the cylinder 36, tends to keep the two cylinders permanently in contact.
A second set of elastic washers 26, placed between the side 25 of the cup 33 and the cylinder 30, with interposed thrust ball bearings 27, tends to keep the whole mechanism permanently lowered, so that the rim 29 forming part of the cylinder 30 rests on the bearing surface 49 of the cup.
When the jack 32 is operated, the conical sleeve 39, first guided by the lug 15 and the matching slide 16, and then by the lug 3 and its slide 4, moves downwards until the two halves of the connectors, such as l and 2, fit into each other and are pushed home.
Further operation of the jack 32 forces the cylinder 30 to move away from the bearing surface 49 and compress the washers 26, thus providing an elastic contact between 1 and 2, to compensate for slight relative movements which could separate the component 45 and the cup 33 during operations, or bring them closer together.
An upper stop 28 limits the elastic movement of the mechanism upwards. The length of travel of the jack 32 is ad justed to ensure that the cylinder 30 always remains below this stop.
A rubber ring 37, placed between the cylinder 36 and the support 38, allows the sleeve 39 to adapt to the final adjustment of the connectors 1 and 2.
Finally, large apertures 43 in the component 45 allow any dirt which may have collected and which could prevent the connectors from fitting together properly to be eliminated.
In addition, constant injection of oil is provided by pipes such as 17, while the cup 33 is moving towards the component 45, so as to provide a permanent oil bath for apertures such as 2, to prevent contact with the water.
What we claim is:
i. A connector for bringing to the surface or submerging a metal object containing remote-controlled instruments, and comprising a mobile cylindrical cup which fits easily on to an inner component which also revolves, the cup being connected to a cable by a threaded section and the inner com ponent being attached to the object to be submerged or raised, characterized in that bolting devices forming part of the cup fit into slots in the inner component when the edge of the said cup is resting on the upper edge of the inner component and the two components are positioned correctly in relation to each other, the bolting devices being pushed into the slots by the operation of a jack which causes a bellcrank lever to pivot on a fixed axis, the upper end of the said jack being connected to another bellcrank lever which can pivot on a second fixed axis and which, when at rest, is held against a block by means of a spring.
