[0023] Please refer to Figures 2-4In the embodiment, the two water sprinklers 10 are fixedly connected with the same moving blocks 11 on the left and right sides, the inner right end of the rectangular frame 1 is rotatably connected with a bidirectional screw rod 15, the inner left end of the rectangular frame 1 is fixedly connected with a guide rod 16, the two moving blocks 11 on the right side are symmetrically and threadedly connected to the outer sides of the front and rear ends of the guide rod 16, and the two moving blocks 11 on the left side are symmetrically and movably connected to the outer sides of the front and rear ends of the bidirectional screw rod 15. Rotating the bidirectional screw rod 15, the two moving blocks 11 on the right side move relatively, and at the same time, the two moving blocks 11 on the left side move relatively on the guide rod 16 synchronously, so that the relative distance between the two water sprinklers 10 is conveniently controlled. The inner front end of the rectangular frame 1 is movably and perpendicularly connected with a connecting rod 17, the rear end of the connecting rod 17 is fixedly connected with the bidirectional screw rod 15, the front end of the connecting rod 17 is fixedly connected with a rotating disc 18, the outer front end of the rotating disc 18 is fixedly connected with a grip column 19, and the rotating disc 18 is rotated by gripping the grip column 19, so that the bidirectional screw rod 15 is rotated by the connecting rod 17. The inner upper end of the overflow box 3 is fixedly connected with a positioning frame 20, and the upper end of the positioning frame 20 is provided with a filter screen 21. After the water source is delivered into the overflow box 3 by an external water pump, the filter screen 21 filters the water, so that larger impurities are prevented from passing through and blocking the spray head 27 to affect the uniformity of spraying, and the filter screen 21 can be removed to clean the accumulated impurities.

[0024] Please refer to Figure 1 In the embodiment, the left end of the rectangular frame 1 is fixedly connected with a fixed rod 22, the upper end of the fixed rod 22 is fixedly connected with an L-shaped limiting pipe 23, one end of an external flexible water pipe is first inserted through the L-shaped limiting pipe 23, and then is fixedly connected with the water supply pipe 6, so that the length of the external flexible water pipe is limited, thereby avoiding that the external flexible water pipe drags and moves to scratch the device and the person pushing the device during movement of the device. The upper right side of the rectangular frame 1 is fixedly connected with a plurality of L-shaped supporting rods 24, the side of the two connecting hoses 9 close to the water outlet pipe 8 is arranged at the upper end of the corresponding L-shaped supporting rod 24, the L-shaped supporting rod 24 supports the connecting hose 9, so that the connecting hose 9 is prevented from falling below the water sprinkler 10 to affect the spraying work. The front end of the rectangular frame 1 is fixedly connected with a connecting plate 25, the bottom of the connecting plate 25 is fixedly connected with a transparent glass baffle 26, and the transparent glass baffle 26 can prevent the person pushing the device from being splashed by the sprayed water.

[0025] During operation, first, a sufficiently long external flexible water hose is passed through the L-shaped limiting pipe 23 and fixed to the water supply pipe 6. Then, the end of the external flexible water hose furthest from the water supply pipe 6 is connected to the outlet of an external water pump. The inlet of the water pump is connected to a stationary water source. The water pump continuously delivers water to the transition tank 3 through the external flexible water hose. The water source is first filtered by the filter screen 21 to remove impurities. At the same time, the water pump 4 is started to draw clean water from the transition tank 3 through the inlet pipe 7, and then delivers it through the outlet pipe 8 to the two connecting hoses 9, which are then distributed to the two sprinkler pipes 10. The water is then sprayed downwards by the nozzles 27 on the sprinkler pipes 10. At this time, the water sprayed from the nozzles 27... To adjust the flow rate, grip the grip column 19 to rotate the turntable 18, which in turn rotates the bidirectional screw 15 via the connecting rod 17. This, along with the guide rod 16 and various moving blocks 11, allows for proper adjustment of the relative distance between the two water pipes 10. This prevents excessive overlap of the spray areas of the two sets of nozzles 27 on the two water pipes 10. The two connecting hoses 9 are then readjusted to rest on the L-shaped support rods 24. The two sets of nozzles 27 on the two water pipes 10 spray water evenly and completely cover the road surface. Finally, grip the handle 14 and use the casters 13 at the bottom of the support rod 12 to move the device. The device travels in a straight line on the cement road surface, performing water spraying and maintenance work.

[0026] Through the above steps, an external water pump delivers a fixed water source to the transition tank 3 via an external flexible water pipe. Then, the water pump 4 draws water from the transition tank 3 through the inlet pipe 7, and distributes it to two sprinkler pipes 10 via the outlet pipe 8 and two connecting hoses 9. The water is then sprayed downwards from the nozzles 27 on each sprinkler pipe 10. The distance between the two sprinkler pipes 10 can be adjusted according to the flow rate of the nozzles 27 to avoid excessive overlap of the spray areas of the two sets of nozzles 27 on the two sprinkler pipes 10, ensuring that the two sets of nozzles 27 on the two sprinkler pipes 10 completely and evenly cover the road surface. Grasp the handle 14 and push using the casters 13 at the bottom of the support rod 12. The device moves in a straight line while simultaneously spraying water onto the cement road surface for maintenance. This device replaces the traditional water truck method, offering lower operating costs, greater flexibility, a wider and more uniform spray area, and better watering results. Furthermore, the removal of the water tank reduces the overall weight, minimizing the risk of damaging incompletely hardened surfaces. This addresses the problems associated with the current method of using water trucks for cement road maintenance, which suffers from high operating costs, limited flexibility, small and uneven spray area, poor effectiveness, and a large total weight of the vehicle and water tank, which can easily damage incompletely hardened surfaces and hinder cement road maintenance.
