[0015] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.
[0016] like Figure 1 , Figure 2 As shown, a municipal road structure of the present invention is arranged on both sides of a road body 1, wherein the drainage system includes a drainage pipe 3, a drainage well 2 connecting the surface of the road body 1 and the drainage pipe 3, the drainage well 2 is vertically arranged on one side of the drainage pipe 3, and at least a part of the drainage well 2 is located above the drainage pipe 3, and a plurality of drainage wells 2 are arranged in sequence along the length direction of the drainage pipe 3, the drainage well 2 has a well pipe 21, and a wellhead 22 is formed at the top opening of the well pipe 21, and the bottom of the drainage groove 5 is horizontal with the wellhead 22 to facilitate the inflow of water; a plurality of drainage ports 23 are opened on the well pipe 21, and the drainage ports 23 are arranged along the well head 22. The pipe 21 is arranged from top to bottom in height direction, and each drain port 23 is connected to a shunt pipe 24. The water flowing into the drainage well 2 flows into the drain pipe 3 through the drain port 23 and the shunt pipe 24. A first filter plate is installed at the opening of each drain port 23. The first filter plate is used to filter the debris flowing into the drain pipe 3. The filtered debris is deposited in the collecting bucket 42 at the bottom of the well pipe 21. A accommodating chamber is also opened at the bottom of the well pipe 21. A submersible pump is installed in the accommodating chamber. The submersible pump is connected to the drain pipe 3 through a pumping pipe. The submersible pump is used to increase the drainage speed or discharge the accumulated water at the bottom of the well pipe 21.
[0017] like Figure 1 , Figure 2 As shown, the cleaning device 4 includes a track 41, a collecting bucket 42 slidably connected to the track 41, and a waterproof motor 43 for driving the collecting bucket 42 to rise and fall. The track 41 is arranged on the inner wall of the well pipe 21, the collecting bucket 42 is in the shape of a dustpan, and the back of the collecting bucket 42 is slidably connected to the track 41. The waterproof motor 43 provides power for the raising and lowering of the collecting bucket 42. The waterproof motor 43 is installed on the upper part of the well pipe 21 and is installed in a waterproof cavity to prevent the waterproof motor 43 from being immersed in water and to reduce the direct contact between the waterproof motor 43 and water.
[0018] When using, Figure 1 , Figure 2 , Figure 3As shown, rainwater and water collected from debris on the road body 1 flow into the drainage trough 5. The drainage trough 5 is in a deep "U" shape. The lower cross-section of the drainage trough 5 has a smooth contour line with a consistent bending direction. A drainage channel 51 is formed in the middle of the drainage trough 5. The water flows through the drainage channel 51 to facilitate drainage and improve the self-cleaning ability. First, it is filtered by the second filter plate 7 covering the top of the drainage trough 5 to block and filter larger volumes of debris. The remaining water flows into the drainage trough 5 and flows to the wellhead 22 of the drainage well 2. Finally, the water flows into the drainage well 2. As more and more water flows in, the water level in the well pipe 21 becomes higher and higher. As the water level rises, the number of drainage outlets 23 flowing from the well pipe 21 to the drainage pipe 3 gradually increases from low to high, thereby increasing the water diversion energy. The force is used to prevent excessive water from pouring in and causing the water in the drainage well 2 to flow back and overflow. At this time, the first filter plate on the drainage outlet 23 further blocks and filters the debris that follows the water flow, and the filtered debris settles downward in the collecting bucket 42 at the bottom of the well pipe 21. When the water level in the well pipe 21 continues to increase, the submersible pump is started to collect the water in the well pipe 21 into the drainage pipe 3 through the pumping pipe, further improving the drainage capacity; when the water level in the well pipe 21 drops to below the lowest drainage outlet 23, the submersible pump is started to pump out the accumulated water in the well pipe 21, and then the waterproof motor 43 is started to lower the collecting bucket 42 and rise along the track 41 until it rises to the wellhead 22, and the second filter plate 7 covering the wellhead 22 is opened to clean up the debris in the collecting bucket 42, and the waterproof motor 43 drives the collecting bucket 42 to descend and fall to the bottom of the well pipe 21.
