Description

Technical Field

[0001] This utility model relates to the field of municipal environmental protection watering technology, and in particular to a municipal environmental protection watering truck with adjustable spraying range. Background Technology

[0002] In the grand system of urban municipal environmental protection, sprinkler trucks occupy a pivotal position, serving as "guardians" of the urban environment. They traverse streets and alleys daily, primarily undertaking key tasks such as road dust suppression and green space irrigation. Regarding road dust suppression, by evenly spraying water, they effectively suppress dust kicked up from roads, reducing dust pollution and significantly improving urban air quality, creating a fresher environment for residents. In the field of green space irrigation, sprinkler trucks precisely provide ample water to roadside plants and park trees and shrubs, helping them thrive. They are a solid guarantee behind the lush urban landscape and make a significant contribution to creating a clean and livable urban environment.

[0003] Traditional sprinkler trucks typically use a single nozzle or nozzle assembly fixedly mounted at the rear of the vehicle. Their horizontal and vertical spraying ranges are essentially fixed, making it difficult to adjust flexibly according to actual operating conditions. When facing roads of varying widths, the fixed spraying range leads to overspraying on narrower roads, wasting water resources, while wider roads fail to be fully covered, resulting in poor dust suppression. Similarly, when irrigating roadside green belts and trees, the fixed nozzle position makes it difficult to accurately spray vegetation of different heights, affecting irrigation effectiveness. Utility Model Content

[0004] To address the shortcomings of fixed spraying ranges on roads of varying widths, which lead to excessive watering and waste on narrower roads, while failing to fully cover wider roads and resulting in poor dust suppression, this invention provides a municipal environmental protection water truck with adjustable spraying range. This truck offers the advantages of adjustable spraying range and height, solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a municipal environmental protection sprinkler truck with adjustable spraying range, including a sprinkler truck body, a stand fixedly installed at the rear of the sprinkler truck body, a movable plate provided at the upper end of the stand, a horizontal pipe fixedly installed at the upper end of the movable plate, two extension pipes slidably connected inside the horizontal pipe, a plurality of spray holes evenly opened on the surface of the extension pipes and the horizontal pipe, a connecting seat fixedly installed at the bottom of one side of the two extension pipes, a convex movable block slidably connected to the surface of the movable plate, grooves provided on both sides of the convex movable block, connecting rods hingedly installed inside the two grooves, the upper ends of the two connecting rods respectively hingedly installed on the inner side of the connecting seat, teeth provided on the front surface of the movable plate, a No. 1 motor installed at the front side of the convex movable block, the output end of the No. 1 motor passing through the convex movable block and a No. 1 gear installed thereon, the inner side of the No. 1 gear meshing with the middle of the teeth.

[0006] Preferably, the movable plate has limit slide rails on both sides, and the inner wall of the convex movable block has protrusions on both sides. The two protrusions are slidably connected to the inside of the limit slide rails. When the two extension tubes are completely inside the horizontal tube, the spray holes on the surface of the extension tube and the horizontal tube correspond to each other.

[0007] By setting up limit rails, the movement trajectory of the convex moving block is constrained, ensuring a stable and precise adjustment of the spray range.

[0008] Preferably, when the convex movable block moves up and down at the upper end of the movable plate, the two connecting rods drive the two extension tubes to move horizontally inside the horizontal tube. The inner side of the stand is provided with a sliding groove, and the bottom of the movable plate is slidably connected to the inner side of the sliding groove.

[0009] By setting up the chute, the movable plate can slide up and down stably, thereby precisely adjusting the position of the extension pipe to change the spraying range.

[0010] Preferably, the upper end of the stand is provided with an opening slot, and a second gear is rotatably connected to the inner side of the opening slot. A second motor is installed on one side of the upper end of the stand, and the output end of the second motor passes through the stand and is connected to one side of the second gear. The inner side of the second gear meshes with the bottom of the teeth.

[0011] By setting up the second gear, the height of the movable plate can be adjusted under the drive of the second motor, thereby changing the spraying height.

[0012] Preferably, a water storage tank is fixedly installed on the upper end of the sprinkler truck body, a high-pressure water pump is installed on the upper end of one side of the sprinkler truck body, a water suction pipe is fixedly installed on one side of the water storage tank, and the other side of the water suction pipe is installed at the pipe connection of the high-pressure water pump.

[0013] By using a high-pressure water pump, the water in the storage tank is pressurized and transported, enabling the water to be powerfully sprayed out from the spray nozzles to meet the needs of different operations.

[0014] Preferably, the output end of the high-pressure water pump is equipped with a water injection pipe, the other end of the water injection pipe is fixedly installed in the middle of one side of the horizontal pipe, and a guardrail is fixedly installed on one side of the sprinkler truck body.

[0015] By installing water injection pipes, water pressurized by high-pressure water pumps is stably delivered to horizontal pipes, ensuring continuous and uniform spraying operations.

[0016] This utility model has the following advantages:

[0017] 1. The No. 1 motor drives the No. 1 gear to rotate. Since the teeth of the No. 1 gear mesh with the front surface of the movable plate, the rotation of the No. 1 gear will drive the convex movable block to move up and down along the surface of the movable plate. Because the connecting rods in the grooves on both sides of the convex movable block are hinged to the connecting seats at the bottom of the extension tubes, the up and down movement of the convex movable block drives the two extension tubes to move horizontally in the horizontal tubes through the connecting rods. When watering is required on a wider road, the extension tubes extend outward, increasing the coverage area of ​​the spray holes and ensuring that the road surface is fully watered. When operating on a narrower road, the extension tubes retract into the horizontal tubes, reducing the spray range and avoiding water waste. This flexible adjustment of the spray range effectively improves the adaptability of the water truck to different road conditions and greatly improves the efficiency of water resource utilization.

[0018] 2. The No. 2 motor drives the No. 2 gear to rotate in the open slot. The No. 2 gear meshes with the bottom of the teeth of the movable plate, thereby driving the movable plate to slide up and down in the slide groove of the stand. When the movable plate moves upward, the horizontal pipe and extension pipe installed on its upper end rise accordingly. At this time, the green belt or trees at higher positions can be irrigated. When the movable plate moves downward, the horizontal pipe and extension pipe are lowered as a whole, which facilitates watering and dust suppression on the road surface at lower positions. The spraying height of the horizontal pipe and extension pipe can be precisely controlled to meet the irrigation needs of vegetation at different heights, improve the effect and quality of greening irrigation, and ensure that urban green plants receive sufficient and appropriate water supply.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 A municipal environmental protection sprinkler truck with adjustable spraying range includes a sprinkler truck body 1. A stand 10 is fixedly installed at the rear of the sprinkler truck body 1. A movable plate 11 is provided at the upper end of the stand 10. A horizontal pipe 7 is fixedly installed at the upper end of the movable plate 11. Two extension pipes 9 are slidably connected inside the horizontal pipe 7. Several spray holes 8 are evenly opened on the surface of the extension pipes 9 and the horizontal pipe 7, so that the water flow can be evenly distributed in the target area when sprayed. The even spraying can effectively suppress road dust and improve the dust reduction effect.

[0027] A connecting seat 12 is fixedly installed on one side of the bottom of the two extension pipes 9. A convex movable block 13 is slidably connected to the surface of the movable plate 11. Grooves 14 are opened on both sides of the convex movable block 13. A connecting rod 15 is hinged inside the two grooves 14. The upper ends of the two connecting rods 15 are respectively hinged to the inner side of the connecting seat 12. Because the connecting rods 15 in the grooves 14 on both sides of the convex movable block 13 are hinged to the connecting seat 12 at the bottom of the extension pipe 9, the up and down movement of the convex movable block 13 drives the two extension pipes 9 to move horizontally in the horizontal pipe 7 through the connecting rods 15. When it is necessary to carry out watering operations on a wider road, the extension pipe 9 extends outward, increasing the coverage of the spray hole 8 and ensuring that the road surface is fully watered. When operating on a narrower road, the extension pipe 9 retracts into the horizontal pipe 7, reducing the spraying range and avoiding water waste. This function of flexibly adjusting the spraying range effectively improves the adaptability of the water truck to different road conditions and greatly improves the utilization efficiency of water resources.

[0028] The front surface of the movable plate 11 is provided with teeth 20. A motor 17 is installed on the front side of the convex movable block 13. The output end of the motor 17 passes through the convex movable block 13 and is equipped with a gear 16. The inner side of the gear 16 meshes with the middle of the teeth 20. The motor 17 drives the gear 16 to rotate. Since the gear 16 meshes with the teeth 20 on the front surface of the movable plate 11, the rotation of the gear 16 will drive the convex movable block 13 to move up and down along the surface of the movable plate 11.

[0029] Please see Figures 2-5 Limiting slide rails 19 are provided on both sides of the movable plate 11. Protrusions 18 are provided on both sides of the inner wall of the convex movable block 13. The two protrusions 18 are slidably connected to the inside of the limiting slide rails 19, effectively constraining the movement trajectory of the convex movable block 13 and preventing it from shaking, shifting, or jamming during movement. When the two extension tubes 9 are completely inside the horizontal tube 7, the spray holes 8 on the surfaces of the extension tubes 9 and the horizontal tube 7 correspond to each other. The 8 components correspond to each other, enabling the water output from the high-pressure water pump 4 to be evenly distributed in the horizontal pipe 7 and the extension pipe 9, and to be stably sprayed out through the spray holes 8. When the convex movable block 13 moves up and down on the upper end of the movable plate 11, the two connecting rods 15 drive the two extension pipes 9 to move horizontally inside the horizontal pipe 7. This means that the device does not require manual adjustment of the nozzle position or complex equipment modifications. The spray range can be quickly changed simply by controlling the movement of the convex movable block 13, which greatly saves working time and reduces the time that vehicles spend on the road.

[0030] The inner side of the support 10 is provided with a sliding groove 24. The bottom of the movable plate 11 is slidably connected to the inner side of the sliding groove 24. The upper end of the support 10 is provided with an opening groove 21. A second gear 22 is rotatably connected to the inner side of the opening groove 21. A second motor 23 is installed on one side of the upper end of the support 10. The output end of the second motor 23 passes through the support 10 and is connected to one side of the second gear 22. The inner side of the second gear 22 meshes with the bottom of the teeth 20. The second motor 23 drives the second gear 22 to rotate in the opening groove 21. The second gear 22 meshes with the bottom of the teeth 20 of the movable plate 11. This causes the movable plate 11 to slide up and down within the groove 24 of the base 10. When the movable plate 11 moves upward, the horizontal pipe 7 and extension pipe 9 installed on its upper end rise accordingly, allowing irrigation of the green belt or trees at higher positions. When the movable plate 11 moves downward, the horizontal pipe 7 and extension pipe 9 are lowered as a whole, facilitating watering and dust suppression on the road surface at lower positions. Precise control of the spraying height of the horizontal pipe 7 and extension pipe 9 can meet the irrigation needs of vegetation at different heights, improving the effect and quality of greening irrigation and ensuring that urban greening plants receive sufficient and appropriate water supply.

[0031] A water tank 2 is fixedly installed on the upper part of the sprinkler truck body 1. A high-pressure water pump 4 is installed on the upper part of one side of the sprinkler truck body 1. A water suction pipe 5 is fixedly installed on one side of the water tank 2. The other side of the water suction pipe 5 is installed at the pipe connection of the high-pressure water pump 4. A water injection pipe 6 is installed at the output end of the high-pressure water pump 4. The other end of the water injection pipe 6 is fixedly installed in the middle of one side of the horizontal pipe 7. The water suction pipe 5 introduces water from the water tank 2 into the high-pressure water pump 4. The high-pressure water pump 4 pressurizes the water and then delivers the high-pressure water to the horizontal pipe 7 through the water injection pipe 6. A guardrail 3 is fixedly installed on one side of the sprinkler truck body 1, which facilitates maintenance work by staff around the vehicle, provides a certain degree of safety, reduces maintenance difficulty, and improves maintenance efficiency.

[0032] Working principle: In actual use, firstly, the high-pressure water pump 4 is started. Water in the water storage tank 2 is drawn and pressurized by the high-pressure water pump 4 through the water pumping pipe 5, and then injected into the horizontal pipe 7 through the water injection pipe 6. When it is necessary to adjust the horizontal spraying range, the first motor 17 is turned on to drive the first gear 16 to rotate. Since the first gear 16 meshes with the teeth 20 on the front surface of the movable plate 11, the rotation of the first gear 16 will cause the convex movable block 13 to move up and down along the surface of the movable plate 11. The up and down movement of the convex movable block 13 is converted into the horizontal movement of the extension tube 9 in the horizontal pipe 7 through the connecting rod 15. When it is necessary to increase the spraying range, the first motor 17 drives the convex movable block 13 to move upward, and the connecting rod 15 pushes the extension tube 9 to extend outward. At this time, the area covered by the spray hole 8 expands. When it is necessary to reduce the spraying range, the first motor 17 drives the convex movable block 13 to move downward, and the connecting rod 15 drives the extension tube 9 to retract inward. The area covered by the spray hole 8 decreases.

[0033] To adjust the spraying height, start motor 23. Motor 23 drives gear 22 to rotate in the slot 21 at the upper end of the stand 10. Gear 22 meshes with the bottom of the teeth 20 of the movable plate 11, causing the movable plate 11 to slide up and down in the groove 24 inside the stand 10. When the movable plate 11 slides upward, the horizontal pipe 7 and extension pipe 9 installed on its upper end rise accordingly, which is suitable for irrigating higher green belts, trees, etc. When the movable plate 11 slides downward, the horizontal pipe 7 and extension pipe 9 are lowered as a whole, which is convenient for watering and dust suppression operations on lower road surfaces.
