Background technology
LNG, i.e. liquefied natural gas, have that calorific value is large, performance high.In recent years, LNG is classified as preferred fuels by many countries, and with annual about 12% rapid growth, become 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 compared with fuel combustion vehicle, can reduce by the noxious gas emission of more than 90%; Secondly, the cost ratio gasoline of LNG and diesel oil low, greatly can reduce use cost; Again, LNG purity is high, and sufficient combustion does not produce carbon distribution, effectively can 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, shrouding 5 and auxiliary girder assembly 6 is provided with in the bottom of double-layer frame 1, double-layer frame 1 is arranged on car chassis by shrouding 5 and auxiliary girder assembly 6, the bracing frame 4 for supporting gas cylinder 2 is provided with in double-layer frame 1, bracing frame 4 is provided with fastening belt 3, and the gas cylinder 2 be positioned on bracing frame 4 can be fixed on bracing frame 4 and not rock by fastening belt 3.
The major defect that the on-vehicle safety gas cylinder framework of said structure form exists is: during use, the outlet of the gas cylinder 2 placed in double-layer frame 1 needs to be tightly connected with multiple pipeline and multiple hydraulic component, in whole double-layer frame, seal joint for connecting each pipeline and hydraulic component at least just has tens, and 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 air, there is potential danger, when particularly automobile is in running state, the gasification natural fuels of diffusion is easily formed in an atmosphere ignites air mass automatically, and this combustion phenomenon may occur.
Summary of the invention
The technical matters of solution required for the present invention is: provide a kind of on-vehicle safety gas cylinder framework whether liquefied natural gas exists leakage problem that can detect in time.
For solving the 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, shrouding and auxiliary girder assembly is provided with in the bottom of double-layer frame, double-layer frame is arranged on car chassis by shrouding and auxiliary girder assembly, the bracing frame for supporting gas cylinder is provided with in double-layer frame, bracing frame is provided with fastening belt, the gas cylinder be positioned on bracing frame can be fixed on bracing frame and not rock by fastening belt, in the surrounding of double-layer frame, periphery guar plate is installed, the top of double-layer frame is provided with top protection lid, top protection lid and periphery guar plate are tightly connected composition protective cover, protective cover by the surrounding of double-layer frame and top seal in protective cover, cover also to be provided with in top protection and protruding upward collect groove, exhausr port is offered at the top collecting groove, gas leakage in protective cover can be discharged by exhausr port, be provided with combustible gas detecting head collecting in groove, during work, combustible gas detecting head is connected with annunciator.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, side top board that form top protection lid, that be connected with two long limits of symmetry or the symmetrical minor face of periphery guar plate is the hang plate be obliquely installed, and hang plate makes gasification natural fuels collect to collecting groove better.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, form top protection lid, be with the side top board that two long limits of symmetry of periphery guar plate are connected with symmetrical minor face the hang plate be obliquely installed, 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 collecting groove is the one in rectangular shape, semicircular arc shape and trapezoidal shape.
Further, aforesaid on-vehicle safety gas cylinder framework, wherein, the periphery guar plate being positioned at that side of cylinder outlet is provided with access door.
The invention has the beneficial effects as follows: in use to leak air problem once certain between the multiple pipeline occurring being connected with cylinder outlet and hydraulic component or multiple seal joint, proportion due to the natural fuels that gasifies is about 0.5 times of air, the gasification natural fuels being positioned at protective cover can from trend highest point---and collect groove and collect and discharge from exhausr port, as long as the concentration being now positioned at the gasification natural fuels collecting groove reaches the concentration that combustible gas detecting head can detect, annunciator will send warning, thus can Timeliness coverage leakage problem, to remove potential danger in time, improve the safety in utilization of vehicle-mounted LNG gas cylinder.
