[0020] The following is combined with Figure 1-3 This application is described in further detail.
[0021] The present application embodiment discloses a drainage device for road maintenance. Figure 1-3A drainage device for highway maintenance includes a shell 1 installed under a road surface, a sewer shaft 2 is installed inside the shell 1, and the sewer shaft 2 includes a pipe 201 installed in the shell 1. A pressure relief port 202 and a return port 203 are sequentially opened on one side of the pipe 201 from top to bottom. Garbage is discharged into a collection filter box 6 through the pressure relief port 202, and then the garbage is intercepted by a reset component 4, and water is returned to the pipe 201 through the return port 203. A reset component 4 is installed inside the pipe 201. The reset component 4 includes a column 401 installed in the pipe 201, and a spiral guide is installed on the side of the column 401. A sleeve 402 is installed on the column 401, and a guide column 403 is installed in the sleeve 402. The guide column 403 is used for guiding and limiting, so that the sleeve 402 can rotate while descending. A filter assembly 3 is installed on the upper end of the sleeve 402. The filter assembly 3 includes a bracket 301 installed on the sleeve 402, a water filter plate 303 is installed on the upper side of the bracket 301, and a cleaning brush 304 that moves up and down along the Z axis is installed on the upper side of the water filter plate 303. The cleaning brush 304 moves up and down synchronously with the water filter plate 303, and the water filter plate 303 and the cleaning brush 304 rotate relative to each other to complete the cleaning of garbage on the water filter plate 303.
[0022] Reference Figure 2 The shell 1 includes a waterproof shell 101 installed under the road surface. A waterproof lining 102 is installed on the outer side of the pipe 201 in the waterproof shell 101 to prevent water from penetrating into the road and affecting the service life of the road. A drainage cavity is preset in the waterproof shell 101, and a collection filter box 6 is installed between the pressure relief port 202 and the return port 203 in the drainage cavity.
[0023] Reference Figure 3 An upper cover 7 is installed on the top of the waterproof housing 101, a drainage notch is preset on the upper side of the pipeline 201 on the upper cover 7, and an inspection port is preset above the drainage cavity on the upper cover 7.
[0024] Reference Figure 3 A support frame is installed on the inner side of the pipe 201, and the column 401 is fixedly installed on the support frame. A return spring 404 is installed between the support frame and the sleeve 402. The return spring 404 is slidably sleeved with the column 401, and the sleeve 402 is elastically supported by the return spring 404. When the pressure of the water above the water filter plate 303 on the water filter plate 303 is less than the deformation elastic force of the return spring 404, the sleeve 402 remains stationary. When the pressure of the water above the water filter plate 303 on the water filter plate 303 exceeds the deformation elastic force of the return spring 404, the sleeve 402 moves downward, so that the water filter plate 303 and the cleaning brush 304 rotate relative to each other, so as to clean the garbage on the water filter plate 303.
[0025] Reference Figure 2A moving ring 302 is rotatably installed on the outer side of the bracket 301 and is slidably connected to the pipe 201. The cleaning brush 304 is connected to the moving ring 302 by bolts. The upper surface of the water filter plate 303 is a slightly convex arc surface, which is convenient for garbage to slide to the edge of the moving ring 302. A number of guide plates 5 are installed in the pipe 201. The upper end of the guide plate 5 passes through the moving ring 302 for sliding connection. The moving ring 302 is guided by the guide plate 5 to ensure the stability of the moving ring 302 sliding along the Z axis. A blocking ring is installed at the lower end of the moving ring 302. The blocking ring is slidably connected to the pipe 201. When the moving ring 302 reaches the pressure relief port 202, the gap below the moving ring 302 and the pressure relief port 202 can be blocked by the blocking ring to prevent garbage from directly entering the pipe 201 through the pressure relief port 202.
[0026] The implementation principle of a drainage device for highway maintenance in the embodiment of the present application is as follows: first, the housing 1 is installed under the road surface and connected to the sewer pipe through the pipe 201. When the pipe 201 is not drained smoothly or is blocked, the water flow will accumulate above the water filter plate 303. When the pressure of the water flow on the water filter plate 303 exceeds the deformation elastic force of the return spring 404, the water filter plate 303 and the movable ring 302 are pressed downward, thereby causing the bracket 301, the water filter plate 303, and the sleeve 402 to move downward, causing the return spring 404 to contract, and the water filter plate 303 and the movable ring 302 to move downward. During the movement, the column 401 drives the sleeve 402 to drive the water filter plate 303 and the water filter plate 303 to rotate, so that the water filter plate 303 and the cleaning brush 304 rotate relative to each other, and the garbage on the upper surface of the water filter plate 303 is cleaned by the cleaning brush 304. During the cleaning process, the moving ring 302 moves down to a state aligned with the pressure relief port 202, and the water and garbage are discharged into the drainage cavity through the pressure relief port 202, and flow back into the pipe 201 through the reflux port 203, and the garbage passing through is intercepted by the collection filter box 6, and the collection filter box 6 can be cleaned regularly.
