Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a maintenance device for uniformly spraying water onto roads. Background Technology

[0002] After roads are built and put into use, they require regular maintenance to extend their service life and reduce wear and tear. Spraying is a common maintenance method, cleaning dust from the road surface and cooling the road in hot summer weather to prevent cracking due to thermal expansion and contraction. However, current water spraying systems mainly consist of water trucks. These trucks pump water from their tanks, but urban roads experience heavy traffic, causing water trucks to travel at inconsistent speeds. Existing water trucks cannot adjust the water volume according to vehicle speed, resulting in uneven water distribution. Furthermore, different roads have different widths, and existing water trucks cannot adjust the spraying area accordingly. Utility Model Content

[0003] The purpose of this invention is to provide a road watering maintenance device for uniform spraying, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a road watering maintenance device for uniform spraying, comprising a fixed plate and a wheel axle. A connecting cylinder is fixedly connected to the lower end of the fixed plate, and a spraying plate is fixedly connected to the lower end of the connecting cylinder. Spraying pipes are inserted into the inner walls of both ends of the connecting cylinder, and the spraying pipes move horizontally within the connecting cylinder. Spraying holes are provided at the lower ends of both the spraying pipes and the spraying plate. A pressure cylinder is fixedly connected to the left side of the fixed plate, and a water inlet is provided at the side end of the pressure cylinder. A connecting plate is fixedly connected to the upper end of the pressure cylinder. A water passage is provided in the middle of the connecting plate, and drain holes are provided at both ends of the water passage. The drain holes are connected to the connecting cylinder through a flexible hose or a metal water pipe, and the connection point is located in the middle of the connecting cylinder. A piston is slidably connected to the middle of the pressure cylinder, and a telescopic component is fixedly connected to the lower end of the piston. A control wheel is fixedly connected to the middle of the wheel axle.

[0005] Preferably, the control wheel has a valley and a peak, and the lower end of the telescopic member is rotatably connected to an auxiliary wheel, which abuts against the upper surface of the control wheel.

[0006] Preferably, the telescopic component is a columnar structure with a large diameter in the middle and small diameters at both ends, and a telescopic spring is provided between the telescopic component and the pressure cylinder, with the upper end of the telescopic component located inside the pressure cylinder.

[0007] Preferably, the piston is a rubber stopper, and the length of the piston is greater than the distance between the lower end of the water inlet and the connecting plate.

[0008] Preferably, the outer surface of the spray pipe is threaded, an adjusting gear is threaded in the middle of the spray pipe, a rubber pad is provided at the overlapping point of the connecting cylinder and the spray pipe, the spray plate is T-shaped, and both ends of the spray plate extend to the adjusting gear.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the vehicle speed changes, the wheel axle and wheel speed of the car also change. The wheel axle drives the control wheel to rotate. When the control wheel rotates, the piston moves repeatedly inside the pressure cylinder, thereby pressurizing the water entering the pressure cylinder. The pressurized water is squeezed into the connecting cylinder and then sprayed out by the spray plate and spray pipe. When the wheel axle speed changes, the amount of water sprayed will also be different, thereby ensuring that the road can be sprayed evenly when the vehicle is driving. When the width of the road changes, the two spray pipes will change position to adapt to roads of different widths, ensuring that roads of different widths are sprayed evenly.

[0013] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] Please see Figure 1-2This utility model provides a technical solution: a road watering maintenance device for uniform spraying, including a fixed plate 1 and a wheel axle 3. A connecting cylinder 4 is fixedly connected to the lower end of the fixed plate 1, and a spraying plate 5 is fixedly connected to the lower end of the connecting cylinder 4. Spraying pipes 6 are inserted into the inner walls of both ends of the connecting cylinder 4, and the spraying pipes 6 move horizontally within the connecting cylinder 4. Spraying holes are provided at the lower ends of both the spraying pipes 6 and the spraying plate 5. A pressure cylinder 2 is fixedly connected to the left side of the fixed plate 1. A water inlet 13 is provided at the side end of the pressure cylinder 2. A connecting plate 14 is fixedly connected to the upper end of the pressure cylinder 2. A water passage 15 is provided in the middle of the connecting plate 14 for water to pass through. Drainage holes 16 are provided at both ends of channel 15. The drainage holes 16 are connected to the connecting cylinder 4 through a hose or metal water pipe, and the connection part is located in the middle of the connecting cylinder 4. A piston 9 is slidably connected in the middle of the pressurizing cylinder 2. A telescopic component 10 is fixedly connected to the lower end of the piston 9. A control wheel 8 is fixedly connected in the middle of the wheel axle 3. Water flows from the inlet hole 13 into the pressurizing cylinder 2. The wheel axle 3 drives the control wheel 8 to rotate, thereby driving the piston 9 to move back and forth in the pressurizing cylinder 2, pressurizing the water entering the pressurizing cylinder 2, thereby squeezing the water out of the pressurizing cylinder 2 into the connecting cylinder 4, and then spraying it out by the spray plate 5 and the spray pipe 6.

[0015] The control wheel 8 has a trough and a peak. The lower end of the telescopic component 10 is rotatably connected to an auxiliary wheel 11, which abuts against the upper surface of the control wheel 8. The telescopic component 10 is a columnar structure with a larger diameter in the middle and smaller diameters at both ends. A telescopic spring 12 is provided between the telescopic component 10 and the pressure cylinder 2. The upper end of the telescopic component 10 is located inside the pressure cylinder 2. The piston 9 is a rubber stopper, and the length of the piston 9 is greater than the distance between the lower end of the water inlet hole 13 and the connecting plate 14. The telescopic spring 12 can control the auxiliary wheel 11 to always abut against the side of the control wheel 8. When the control wheel 8 rotates, the auxiliary wheel 11 moves on the trough and peak of the control wheel 8, thereby pushing the piston 13 to move back and forth inside the pressure cylinder 2 to squeeze the water. The squeezing frequency is controlled according to the vehicle speed to ensure uniform water spraying.

[0016] The outer surface of the spray pipe 6 has a threaded structure, and the middle thread of the spray pipe 6 is connected to an adjusting gear 7. When the adjusting gear 7 rotates, it controls the length of the spray pipe 6, adapting to roads of different widths and making it more adaptable. A rubber pad is provided at the joint where the connecting cylinder 4 and the spray pipe 6 meet, sealing the joint and preventing water from being sprayed at the same point. The spray plate 5 has a T-shaped structure, with both ends extending to the adjusting gear 7 to ensure uniform road spraying.
