The utility model provides a concrete embodiment, after the drainage vehicle was transported to the scene by the transport vechicle, the long-range visual control of drainage vehicle accessible goes to the operation point and carries out the operation, because the drainage vehicle includes track chassis 110, can go on the road surface of complicacy, because lift telescoping device 130 and can drive suction pump 120 for track chassis 110 motion in order to be in operating position or storage position, when lifting telescoping device 130 and driving suction pump 120 and be in storage position, suction pump 120's bottom is higher than track chassis 110's bottom, and the front end in track chassis 110 has certain inclination, make track chassis 110 can satisfy certain climbing requirement and obstacle crossing requirement, in order to satisfy the complicated demand of disaster site road surface condition, make the environmental adaptability of drainage vehicle strong, the application range has been enlarged. When the drainage vehicle arrives at the operation point, the water suction pump 120 can be artificially controlled to be lowered and the water suction pump 120 can be started through the display screen, and the water suction pump 120 is connected with the drainage pipe to suck away the accumulated water or flood on the road surface.

The embodiment of the utility model provides a drainage vehicle, with track chassis 110 and suction pump 120 perfect adaptation, rely on the pneumatic cylinder to realize suction pump 120's operating position and the fast switch-over of storage position, utilize track chassis 110 can realize suction pump 120's quick travel to realize the accurate drainage in each corner, simultaneously under the drainage state, also can adjust from the height of drainage liquid level to suction pump 120's bottom, thereby reach the purpose to the drainage of different ponding pits.

Further, the drainage vehicle also has the following advantages:

because the drainage vehicle is provided with track chassis 110 and lifts the telescoping device for the drainage vehicle can switch at operating position and storage position, and drainage vehicle small in size, and environmental suitability is strong, and convenient transportation can reply complicated road surface environment and quick response relief call, can arrive at the scene and begin to carry out the drainage operation in the shortest time.

The stroke of the first telescopic mechanism 131 and the stroke of the second telescopic mechanism 132 in the lifting telescopic device 130 are reasonably set, so that the working position and the storage position of the suction pump 120 are respectively in the state that the piston rods of two hydraulic cylinders of the two telescopic mechanisms extend out or retract, and the suction pump 120 is prevented from interfering with the hydraulic pump station 140 due to misoperation during manual control.

The shells in the electrical control cabinet 150 and the hydraulic valve module 142 on the drainage vehicle are of an upper-lower layered structure and are sealed by sealing gaskets, the pump station motor 143 is a waterproof motor, and the cable, the wire connector and the oil pipe connector are strictly waterproof, so that the drainage vehicle can operate in rainy days and even can work under the condition of being submerged by water, and the application range of the drainage vehicle is further expanded.
