Description

Technical Field

[0001] This utility model relates to the field of highway flushing equipment, specifically a high-pressure flushing device for highways. Background Technology

[0002] Highways have brought great convenience to our daily travel, but due to natural disasters, traffic accidents and littering by some drivers and passengers, the amount of garbage on highways has increased. Moreover, there are many restrictions on cleaning up garbage on highways, making it a difficult problem to remove garbage from highways. There are three methods for collecting garbage on highways: roadside collection, mechanical collection, and collection using integrated equipment. Currently, collection using integrated equipment is the most common method. Among them, the commonly used integrated equipment is the highway high-pressure water flushing equipment, which uses high-pressure water cannons to flush garbage on the highway to the median strip in the middle of the road. Finally, staff will clean the median strip regularly. Traditional high-pressure water flushing trucks generally use rigid water tanks with fixed volume. The fixed volume of the rigid water tanks occupies most of the space in the truck bed, resulting in the truck bed being unable to be used to transport other tools or materials when the equipment is idle, thus wasting space resources.

[0027] This utility model provides an improved high-pressure water flushing device for highways, the working principle of which is as follows: First, when using the water storage device 3, the flexible water storage tank 31 needs to be unfolded for water storage. The output shaft of the control motor 3471 drives the synchronous pulleys of the synchronous pulley set 3472 to rotate. The two synchronous pulleys of the synchronous pulley set 3472 are connected by a synchronous belt, so that the two synchronous pulleys of the synchronous pulley set 3472 rotate synchronously. The two synchronous pulleys drive the screws 346 of the two sets of support components 34 to rotate. The rotation of the screws 346 drives the movable block 345 to move to the left through the threaded connection between the screws 346 and the movable block 345. The movable block 345 drives the leftmost slider 343 to move to the left. 3. The left side plate 32 moves to the left in sync. The left side plate 32 moves to the left, causing the left side of the flexible water storage tank 31 to unfold. When the leftmost slider 343 moves to the left, the slider 343 drives the other sliders 343 to move in sync through the connecting rod assembly 344. The support rods 3443 of the connecting rod assembly 344 support the bottom of the flexible water storage tank 31 at equal intervals. When the left side plate 32 moves to the left, it causes the scissor-type telescopic frame 35 to extend. The scissor-type telescopic frame 35 supports the front and rear sides of the flexible water storage tank 31 to ensure the strength of the flexible water storage tank 31. Second, when filling the flexible water storage tank 31 with water, the second water pumping pipe 387 is taken out from the storage box 388, the first reversing valve 382 is controlled to connect the extraction port of the high-pressure water pump 381 to the second water pumping pipe 387, and the output port of the second reversing valve 385 is controlled to connect to the second water outlet pipe 384. The second water pumping pipe 387 is connected to an external water source, and the high-pressure water pump 381 is controlled to operate to extract water from the external water source through the second water pumping pipe 387 and deliver it to the flexible water storage tank 31 through the second water outlet pipe 384. Third, when flushing the highway, the electric push rod 56 is controlled to drive the straight pipe 51 to move down, and the height of the straight pipe 51 is adjusted. The reversing valve 382 is controlled to connect the extraction port of the high-pressure water pump 381 to the water pumping pipe 386, and the reversing valve 385 is controlled to connect the output port of the high-pressure water pump 381 to the water outlet pipe 383. When it is necessary to flush both sides of the straight pipe 51 at the same time, the solenoid valves 53 at both ends of the straight pipe 51 are opened at the same time. When it is only necessary to flush one side, the solenoid valve 53 on the corresponding side is opened, and the high-pressure water pump 381 is controlled to operate to extract water from the flexible water storage tank 31 through the water pumping pipe 386. After passing through the water outlet pipe 383, the telescopic pipe 55 and the straight pipe 51, the water is sprayed out through the nozzle 54. Fourth, when the water storage device 3 is not in use, the flexible water storage tank 31 needs to be folded and retracted to reduce its space occupation. The output shaft of the control motor 3471 is rotated in reverse, which drives the screw 346 to rotate in reverse through the synchronous wheel set 3472, thereby driving the movable block 345, which in turn drives the leftmost slider 343 and the left side plate 32 to move to the right. The left side plate 32 moves to the right, pushing the flexible water storage tank 31 to retract, and the connecting rod assembly 344 between the sliders 343 retracts. The support rod 3443 moves upward, and the bottom distance between the first connecting rod 3441 and the second connecting rod 3442 is shortened, which shortens the distance between the two sliders 343, thus completing the retraction of the flexible water storage tank 31.
