[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] As attached Figure 1 To Attachment Figure 5 As shown:

[0027] Embodiment 1: The utility model provides an urban flood prevention drainage system, comprising a drainage pipe 1, a connecting pipe 2 arranged in the drainage pipe 1, a fixing mechanism 3 arranged outside the connecting pipe 2, and a filtering mechanism 4 arranged on the top of the fixing mechanism 3.

[0028] Furthermore, the filtering mechanism 4 includes a fixing plate 401, an impeller 402 arranged inside the fixing plate 401, an arc rod 403 arranged outside the impeller 402, a groove plate 404 arranged at the bottom of the fixing plate 401, a support rod 406 arranged at the bottom of the groove plate 404, and a partition 405 arranged at the top of the fixing mechanism 3.

[0029] Furthermore, the support rod 406 is provided in several groups, the bottom of the support rod 406 is fixedly connected to the top of the fixing mechanism 3, the bottom of the groove plate 404 is fixedly connected to the top of the support rod 406, the bottom of the fixing plate 401 is fixedly connected to the top of the groove plate 404, one end of the impeller 402 is rotatably connected to the inside of the fixing plate 401, and the arc rod 403 is provided in several groups, and the side wall of the arc rod 403 is rotatably connected to the outside of the impeller 402.

[0030] Furthermore, the fixing mechanism 3 includes a fixing seat 301, a sleeve 302 arranged on the top of the fixing seat 301, a filter plate 303 arranged in the sleeve 302, a movable plate 306 arranged at the bottom of the sleeve 302, a spring 305 arranged in the movable plate 306, and a connecting plate 304 arranged in the movable plate 306.

[0031] Furthermore, the bottom of the sleeve 302 is embedded in the interior of the fixed seat 301, the filter plate 303 is located on the outside of the impeller 402, the spring 305 is provided in several groups, one end of the spring 305 is fixedly connected to the interior of the movable plate 306, the connecting plate 304 is fixedly connected to the interior of the movable plate 306 through the spring 305, and the bottom of the movable plate 306 is embedded in the interior of the fixed seat 301.

[0032] Furthermore, the interior of the fixing seat 301 is fixedly connected to the exterior of the connecting pipe 2 , and one end of the connecting pipe 2 is embedded in the top of the drain pipe 1 .

[0033] As can be seen from the above, by placing the sleeve 302 on the top of the connecting pipe 2, by pushing the sleeve 302, the connecting plate 304 at the bottom of the sleeve 302 moves downward, and the bottom of the connecting plate 304 is embedded in the interior of the fixed seat 301. When the connecting plate 304 enters the fixed seat 301, the fixed seat 301 pushes the movable plate 306 to move, and the movable plate 306 pushes the spring 305 to be in a compressed state. The movable plate 306 is completely embedded in the interior of the connecting plate 304. When the movable plate 306 moves to the groove opened in the fixed seat 301, the reverse force of the spring 305 is used to make the spring 305 push the movable plate 306 to move, so that the movable plate 306 is fixed to the fixed seat 301. The sleeve 302 is fixed on the outside of the connecting pipe 2 as a whole to ensure the filtering effect on the water flow. When a large amount of rainfall occurs in the city, the water flow will enter the drainage pipe 1 through the drainage grooves opened on the city roads. The water flow will first contact the top of the fixing plate 401 when flowing. It is worth noting that the fixing plate 401 is located in the urban drainage groove, and the fixing plate 401 and the sleeve 302 are both separated from the inside of the drainage groove to avoid the arc rod 403 from contacting the inside of the drainage groove, making the arc rod 403 unable to rotate. When the water flow is small, the water flow enters the inside of the groove plate 404, and the cooperation between the support rod 406 and the groove plate 404 is utilized to prevent larger garbage from being blocked in the sleeve. The inside of the sleeve 302, and the smaller garbage will first enter the inside of the groove plate 404. At the same time, the partition 405 on the top of the sleeve 302 is inclined. When the smaller garbage contacts the partition 405, the partition 405 blocks the garbage, so that the garbage stays on the outside of the sleeve 302, and the water flows into the inside of the sleeve 302. It is worth noting that the water flow will drive the gravel into the sleeve 302. In order to avoid the gravel from being blocked at the connecting pipe 2, the sleeve 302 and the filter plate 303 cooperate to make the gravel flow in two directions under the rotation of the impeller 402. It is worth noting that when the impeller 402 rotates slowly, a small amount of water will be thrown into one side of the filter plate 303, from In order to reduce the simultaneous flow of sand and gravel, the impeller 402 is rotated to drive the arc rod 403 to rotate, and the garbage at the groove plate 404 is pushed by the rotation of the arc rod 403. When a large number of leaves are accumulated at the groove plate 404, the support rod 406 and the groove plate 404 cooperate to make the leaves accumulate on the outside of the support rod 406 to prevent the leaves from entering the inside of the sleeve 302. The impeller 402 is rotated to drive the arc rod 403 to rotate, so that the arc rod 403 cleans the leaves and keeps the side wall of the sleeve fixing plate 401 in a tidy state, thereby ensuring the flow of water and avoiding waterlogging.

[0034] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the support rod 406 is provided in several groups, the bottom of the support rod 406 is fixedly connected to the top of the fixing mechanism 3, the bottom of the groove plate 404 is fixedly connected to the top of the support rod 406, the bottom of the fixing plate 401 is fixedly connected to the top of the groove plate 404, one end of the impeller 402 is rotatably connected to the inside of the fixing plate 401, and the arc rod 403 is provided in several groups, and the side wall of the arc rod 403 is rotatably connected to the outside of the impeller 402.

[0035] As can be seen from the above, when a large amount of gravel is accumulated in the fixing mechanism 3, the fixing plate 401 is placed in the water in reverse, and the arc rod 403 is rotated in the reverse direction so that the impeller 402 is driven to rotate when the arc rod 403 rotates. The rotation of the impeller 402 allows the water flow to pass through the fixing mechanism 3 and enter the inside of the impeller 402. The reverse rotation of the impeller 402 allows the water flow to drive the gravel to flow into the inside of the groove plate 404, thereby achieving a cleaning effect on the fixing mechanism 3.
