Technical field
The present invention relates to a kind of technical field of low floor double-layer public transport vehicle, particularly relate to a kind of combustion gas chamber structure of air-conditioned combustion gas double-layer public transport vehicle.
Background technology
At present, conventional double-layer public transport vehicle is diesel-powered vehicle, the economic not environmental protection of traditional diesel-powered vehicle, adopt bus using natural gas to alleviate auto pollution, wherein high-capacity low floor double-layer public transport vehicle take natural fuels as fuel, under combustion gas storehouse is arranged on the chair top in passenger cabin stage casing, the floor of bottom underframe must be raised, and so just cannot realize the maximization design of low floor area, and the extended length of Gas Pipe, pipe damages and strengthens, and the degree of utilization of fuel cannot improve.
Summary of the invention
The invention provides a kind of energy-conserving and environment-protective, compact conformation, and the double-layer public transport vehicle combustion gas chamber structure that low floor area maximizes design can be realized.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of air-conditioned double-layer public transport vehicle combustion gas chamber structure, described combustion gas storehouse is arranged on the rear end of lower floor's passenger cabin, and combustion gas connects engine bin behind storehouse, engine bin is provided with air-conditioning storehouse, is provided with bottom air-conditioning return air passage in combustion gas storehouse.
Further, be provided with a pair in the middle part of the bottom surface in described combustion gas storehouse for placing the fixed support of gas tank, the both sides, bottom surface in combustion gas storehouse are provided with rain groove, are provided with covering at the bottom of storehouse between this rain groove and fixed support and two side, bottom surface, combustion gas storehouse.
Preferably, covering at the bottom of described storehouse is obliquely installed to rain groove place.
Further, described bottom air-conditioning return air passage is made up of multiple rectangular tube and covering, the top of bottom air-conditioning return air passage and the bottom surface on two layers of floor are fitted, the ventilation inlet of return air channel is positioned at the upper front end in combustion gas storehouse, air outlet is communicated with air-conditioning storehouse, adopts sealing member to seal into and out of air port and junction, two layers of floor.
From above technical scheme, the present invention has following beneficial effect:
Combustion gas storehouse is arranged on bottom passenger cabin rear end and with engine bin and air-conditioning storehouse compact siro spinning technology, substantially reduce the length of gas pipeline, reduce degradation of energy, improve the degree of utilization of fuel, the maximization of bottom passenger cabin low floor area can be realized, enhance the degree of utilization in car load space; Arrange rain groove in combustion gas storehouse, for dredging the rainwater in combustion gas storehouse, covering at the bottom of storehouse is obliquely installed to rain groove place, and lead rainwater rain groove, prevents the bottom surface in combustion gas storehouse from getting rusty.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present invention is described in detail.
The invention provides a kind of low floor double-layer public transport vehicle combustion gas chamber structure, from Fig. 1 and Fig. 2, combustion gas storehouse 1 is arranged on the behind of last row's chair top 11 of lower floor's passenger cabin rear end, engine bin 2 is connect behind combustion gas storehouse 1, engine bin 2 is provided with air-conditioning storehouse 3, three storehouse compact siro spinning technology, the upper end in combustion gas storehouse 1 is provided with bottom air-conditioning return air passage 4.
As shown in Figures 2 and 3, this bottom air-conditioning return air passage 4 forms support by multiple rectangular tube, adopt the galvanized plate of thick 1mm as covering, the top of bottom air-conditioning return air passage and the bottom surface of two layers of base plate 8 are fitted, the ventilation inlet 9 of return air channel is positioned at the upper front end in combustion gas storehouse 1, air outlet is communicated with air-conditioning storehouse 3, adopts sealing member 10 to seal into and out of upper end, air port and junction, two layers of floor 8.
As shown in Figure 3 and Figure 4, a pair is provided with for placing the fixed support 5 of gas tank in the middle part of bottom surface, combustion gas storehouse 1, both sides, bottom surface are equipped with rain groove 6, and be provided with covering 7 at the bottom of storehouse between this rain groove and fixed support and two side, bottom surface, combustion gas storehouse, covering at the bottom of this storehouse is obliquely installed into little inclined-plane to rain groove 6 place.
The fuel used in combustion gas storehouse 1 of the present invention is a kind of liquefied natural gas, when bus travels, liquid natural fuels absorbs a large amount of heats in the process of vaporization, temperature in combustion gas storehouse 1 is lower, can to the return air cooling in the bottom air-conditioning return air passage 4 be arranged in combustion gas storehouse, improve the refrigeration usefulness of air-conditioning, economize energy.
Gas tank can pour the liquified natural gas of 146kg compression, continual mileage 500km, average gas consumption are about 29kg/km, compares current ordinary diesel oil car fuel cost and reduces about 23%; And the combustion gas storehouse of this kind of car is the air-conditioning return air lane device being provided with lower floor's passenger cabin, be positioned at the afterbody of car, maximization and the car load space availability ratio that can realize bottom passenger cabin low floor area maximize, and also can reduce the length of Gas Pipe, improve the object of the degree of utilization of fuel
The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
