Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-5As shown in the figure, a road surface sprinkling device for highway maintenance includes: a mobile vehicle 1, a water storage tank 2 is installed at the top of the mobile vehicle 1, a water pump 3 is installed on one side of the water storage tank 2, and a sprinkling mechanism 4 is arranged at the top of the water storage tank 2; among them, the sprinkling mechanism 4 includes a fixing frame 41 fixedly connected to the top of the water storage tank 2, water pipes 42 are fixedly connected to both the top and the bottom of the fixing frame 41, the water outlet of the water pump 3 is communicated with a connecting pipe 43, both water pipes 42 are communicated with the connecting pipe 43, and evenly distributed sprinkling pipes 44 are fixedly connected to the surface of the water pipe 42. Both the top and the bottom of the fixing frame 41 are slidably connected with racks 45, evenly distributed gears 46 are meshed with the surface of the racks 45, the gears 46 correspond to the sprinkling pipes 44 one by one, one end of the gear 46 is fixedly connected to the surface of the corresponding sprinkling pipe 44, the other end of the gear 46 is rotatably connected to the inner wall of the fixing frame 41, and a driving assembly 47 is arranged at the top of the water storage tank 2. An inlet is arranged at the top of the water storage tank 2, and an external aqueous solution can enter the water storage tank 2 through the inlet. The water inlet of the water pump 3 is communicated with the water storage tank 2.

[0025] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the driving assembly 47 includes a motor 471 fixedly connected to the top of the water storage tank 2. A second cam 479 and a first cam 472 are sequentially fixedly connected to the surface of the output shaft of the motor 471 from top to bottom. A first trigger plate 473 is fixedly connected to one side of the upper rack 45, and a second trigger plate 474 is fixedly connected to one side of the lower rack 45. Fixed blocks 475 are fixedly connected to both the top and the bottom of the fixing frame 41. Springs 476 are fixedly connected to one side of both the first trigger plate 473 and the second trigger plate 474, and the other ends of the springs 476 are fixedly connected to one side of the corresponding fixed blocks 475. The other side of the first trigger plate 473 is attached to the surface of the second cam 479, and the other side of the second trigger plate 474 is attached to the surface of the first cam 472. The highest point of the first cam 472 and the lowest point of the second cam 479 are in the same vertical plane.

[0026] When sprinkling water on the road surface, pull the mobile vehicle 1 to move, start the water pump 3 to make the aqueous solution in the water storage tank 2 enter the connecting pipe 43. The aqueous solution will enter both water pipes 42 through the connecting pipe 43 and be sprayed on the road surface simultaneously through the multiple sprinkling pipes 44 on the surfaces of the two water pipes 42.

[0027] Meanwhile, the controller starts the motor 471 to drive the first cam 472 and the second cam 479 to rotate simultaneously. When the second cam 479 rotates from the lowest point to the highest point and contacts the first trigger plate 473, the second cam 479 pushes the first trigger plate 473 to drive the upper rack 45 to move to the farthest distance, and the upper spring 476 is compressed. At this time, the upper rack 45 will drive multiple upper gears 46 to rotate clockwise, thereby driving the other ends of multiple upper spray pipes 44 to rotate clockwise. Meanwhile, when the second cam 479 rotates from the lowest point to the highest point and contacts the first trigger plate 473, the first cam 472 will rotate from the highest point to the lowest point and contact the second trigger plate 474. Under the action of the lower spring 476, the second trigger plate 474 drives the lower rack 45 to move horizontally in the opposite direction to the upper rack 45, thereby driving multiple lower gears 46 to rotate counterclockwise and driving the other ends of multiple lower spray pipes 44 to rotate counterclockwise. Therefore, when the first cam 472 and the second cam 479 continue to rotate, the rotation direction of the upper rack 45 driving the upper gears 46 is always opposite to the rotation direction of the lower rack 45 driving the lower gears 46, so that the upper spray pipes 44 and the lower spray pipes 44 rotate in opposite directions simultaneously, forming an interlaced water spray on the road surface.

[0028] As Figure 4 shown, a limiting rod 477 is fixedly connected to one side of each of the first trigger plate 473 and the second trigger plate 474, and the other end of the limiting rod 477 penetrates through the corresponding fixing block 475. The surface of the limiting rod 477 is slidably connected to the inner wall of the corresponding fixing block 475, and the first trigger plate 473 and the second trigger plate 474 will drive the corresponding limiting rods 477 to move synchronously when they move.

[0029] As Figure 2 shown, the middle part of the spray pipe 44 is a flexible pipe. When the gear 46 drives the other end of the spray pipe 44 to rotate, the middle part of the spray pipe 44 will deform.

[0030] As Figure 5 shown, balls 478 are rotatably connected to the surfaces of both the first cam 472 and the second cam 479. When the first cam 472 and the second cam 479 rotate and push the second trigger plate 474 and the first trigger plate 473 to move, the balls 478 will rotate.

[0031] As Figure 3 shown, the connecting pipe 43 is a three-way pipe. One end of the connecting pipe 43 is connected to the water outlet of the water pump 3, and the other two ends of the connecting pipe 43 are respectively connected to two water pipes 42. After the aqueous solution enters the connecting pipe 43, it will enter the two water pipes 42 simultaneously.

[0032] When the utility model is in use and sprinkles water on the road surface, the moving vehicle 1 is pulled to move, and the water pump 3 is started, so that the aqueous solution in the water storage tank 2 enters the two water pipes 42 at the same time through the connecting pipe 43, and the multiple spraying pipes 44 spray on the road surface at the same time. At the same time, the motor 471 is started to drive the first cam 472 and the second cam 479 to rotate at the same time. When the second cam 479 rotates from the lowest point to the highest point and contacts the first trigger plate 473, the second cam 479 pushes the first trigger plate 473 to drive the upper rack 45 to move and makes the multiple upper gears 46 rotate clockwise, thereby driving the other ends of the multiple upper spraying pipes 44 to rotate clockwise. At the same time, when the second cam 479 rotates from the lowest point to the highest point and contacts the first trigger plate 473, the first cam 472 will rotate from the highest point to the lowest point and contact the second trigger plate 474. Under the action of the lower spring 476, the second trigger plate 474 drives the lower rack 45 to move horizontally in the opposite direction to the upper rack 45, and drives the multiple lower gears 46 to rotate counterclockwise, thereby driving the other ends of the multiple lower spraying pipes 44 to rotate counterclockwise. Therefore, when the first cam 472 and the second cam 479 continue to rotate, the rotation direction of the upper rack 45 driving the upper gear 46 is always opposite to the rotation direction of the lower rack 45 driving the lower gear 46, so that the upper spraying pipe 44 and the lower spraying pipe 44 rotate in opposite directions at the same time, forming an alternating water spray on the road surface.

[0033] It should be noted that in the above description, the water pump 3, the motor 471, etc. are all devices with relatively mature applications in the prior art, and the specific models can be selected according to actual needs. At the same time, the power supply of the water pump 3 and the motor 471 can be powered by an internal power supply or by mains power, and the specific power supply method is selected according to the situation and will not be elaborated here.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
