LNG, i.e. liquefied natural gas, has that calorific value is large, performance high.In recent years, LNG is classified as preferred fuels by many countries, and with approximately 12% rapid growth every year, becomes the whole world and increase one of the swiftest and the most violent energy.Because LNG can bring the comprehensive benefit of highly significant, at traffic transport industry, promote the LNG energy and become trend of the times: first, use the vehicle of LNG to compare with fuel combustion vehicle, can reduce more than 90% noxious gas emission; Secondly, cost ratio gasoline and the diesel oil of LNG are low, can greatly reduce use cost; Again, LNG purity is high, and sufficient combustion does not produce carbon distribution, can effectively alleviate parts depreciation, increasing service life of engine.
At present on vehicle for loading the on-vehicle safety gas cylinder framework of LNG gas cylinder, comprise: for loading the double-layer frame 1 of gas cylinder, in the bottom of double-layer frame 1, be provided with shrouding 5 and auxiliary girder assembly 6, double-layer frame 1 is arranged on car chassis by shrouding 5 and auxiliary girder assembly 6, in double-layer frame 1, be provided with for supporting the bracing frame 4 of gas cylinder 2, fastening belt 3 is installed on bracing frame 4, and fastening belt 3 can be fixed on bracing frame 4 and do not rock being positioned at gas cylinder 2 on bracing frame 4.
The major defect that the on-vehicle safety gas cylinder framework of said structure form exists is: during use, outlet at the gas cylinder 2 of double-layer frame 1 interior placement need to be tightly connected with a plurality of pipelines and a plurality of hydraulic pressure components and parts, in whole double-layer frame, for connecting the seal joint of each pipeline and hydraulic pressure components and parts, at least just have tens, in use seal joint place there will be gas leak phenomenon unavoidably; If the phenomenon of leaking air, gas leakage---gasification natural fuels can to all the winds diffuse in atmosphere, has potential danger, when particularly automobile is in running state, the gasification natural fuels of diffusion easily forms and automatically ignites air mass in atmosphere, and combustion phenomenon may occur for this.
Summary of the invention
The technical matters of solution required for the present invention is: provide a kind of and can detect in time the on-vehicle safety gas cylinder framework whether liquefied natural gas exists leakage problem.
For addressing the above problem, the technical solution used in the present invention is: described on-vehicle safety gas cylinder framework, comprise: for loading the double-layer frame of gas cylinder, in the bottom of double-layer frame, be provided with shrouding and auxiliary girder assembly, double-layer frame is arranged on car chassis by shrouding and auxiliary girder assembly, in double-layer frame, be provided with for supporting the bracing frame of gas cylinder, fastening belt is installed on bracing frame, fastening belt can be fixed on bracing frame and not rock being positioned at gas cylinder on bracing frame, surrounding at double-layer frame is provided with periphery guar plate, at the top of double-layer frame, be provided with top protection lid, top protection lid is tightly connected and forms a protective cover with periphery guar plate, protective cover by the surrounding of double-layer frame and top seal in protective cover, in top protection, cover and be also provided with the protruding upward groove that collects, at the top of collecting groove, offer exhausr port, exhausr port can be discharged the gas leakage in protective cover, within collecting groove, be provided with combustible gas detecting head, during work, combustible gas detecting head is connected with annunciator.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, form top protection lid, symmetrical to grow the side top board that limits or symmetrical minor face be connected be the hang plate being obliquely installed with two of periphery guar plate, the hang plate natural fuels that makes to gasify collects to collecting groove better.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, form top protection lid, grow the side top board that limits are connected with symmetrical minor face and be the hang plate being obliquely installed with two of periphery guar plate are symmetrical, the hang plate natural fuels that makes to gasify collects to collecting groove better.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, the described cross sectional shape that collects groove is a kind of in rectangular shape, semicircular arc shape and trapezoidal shape.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, is provided with access door being positioned at gas cylinder and exporting on the periphery guar plate of that side.
The invention has the beneficial effects as follows: in use once occur exporting a plurality of pipelines of being connected and certain or a plurality of seal joint between the hydraulic pressure components and parts problem that leaks air with gas cylinder, because the proportion of gasification natural fuels is about 0.5 times of air, the gasification natural fuels that is positioned at protective cover can be from trend highest point---and collect that groove collects and discharge from exhausr port, as long as be now positioned at the concentration of the gasification natural fuels that collects groove, reach the concentration that combustible gas detecting head can detect, annunciator will send warning, thereby can find in time gas leakage problem, to remove in time potential danger, improved the safety in utilization of vehicle-mounted LNG gas cylinder.
