[0002] In the urban construction and development of our country, municipal engineering is an important part. Municipal engineering construction refers to the construction of various buildings, structures and equipment for residents within the urban and town planning areas. The construction of various public infrastructure supporting urban life is an important content of municipal engineering construction. Among the public infrastructure construction, the setting of rainwater inlets on roads also plays an important role, and the normal filtration of rainwater inlets affects daily traffic.

[0003] In related technologies, multiple layers of filter meshes are set to filter impurities in rainwater to prevent the impurities in rainwater from blocking the sewer and affecting the inflow of rainwater into the sewer. However, when the impurities in the filter mesh are not cleaned in time and accumulate too much, it may still cause rainwater to be unable to flow into the sewer. It can be seen that the effect of removing sundries in related technologies is poor. Summary of the Utility Model

[0024] A thorn plate 2 with filter holes is arranged below the grid plate 101. Both ends of the thorn plate 2 are detachably connected to the inner side wall of the main body 1. This application does not limit the detachable connection method, and the existing technology can be adopted. A plurality of thorns (not shown in the drawings) are arranged on the thorn plate 2, and the lengths of different thorns are different. By setting thorns with different lengths, gaps may be generated between sundries due to different thorn heights, thereby reducing the possibility of being blocked by sundries.

[0025] A cleaning component 3 is arranged below the thorn plate 2. The cleaning component 3 includes a central shaft 301, three blades 302, three cleaning plates 303 and a sleeve 304. The three blades 302 and the three cleaning plates 303 are both arranged around the sleeve 304. Specifically, the blades 302 are welded to the top end of the sleeve 304, and the cleaning plates 303 are welded to the bottom end of the sleeve 304; the sleeve 304 is connected to the top end of the filter net 4 through the central shaft 301. Specifically, the inside of the sleeve 304 is hollow, and one end of the central shaft 301 is inserted into the hollow part of the sleeve 304, so that the sleeve 304 is rotatably connected to the top end of the central shaft 301. The other end of the central shaft 301 is welded to the vertex of the filter net 4, and the cleaning plate 303 abuts against the outer surface of the filter net 4.

[0026] The filter net 4 is located below the cleaning component 3. The filter net 4 is used to filter rainwater. The filter net 4 includes a conical filter net 401 and a rectangular filter net 402. The bottom edge of the conical filter net 401 is welded to the middle of the rectangular filter net 402. The top end of the conical filter net 401 is welded to the central shaft 301. The blade 302 abuts against the surface of the conical filter net 401. The outer edge of the rectangular filter net 402 abuts against the side wall of the main body 1. Connection components 6 are arranged at the four corners of the rectangular filter net 402, and the main body 1 can be connected through the connection components 6.

[0027] In the embodiment of the present application, the connecting component 6 can be connected to the vertex of the main body 1 or any position on the inner side wall of the main body 1; the connecting component 6 includes a first fixing block 601, a spring 602 and a second fixing block 603; the main body 1 is connected to one side of the first fixing block 601, the other side of the first fixing block 601 is welded to the top end of the spring 602, the bottom end of the spring 602 is welded to the second fixing block 603, and the second fixing block 603 is fixedly connected to the corner of the rectangular filter net 402.

[0029] Furthermore, a plurality of sieve holes are arranged on the conical filter net 401, the rectangular filter net 402 and the collection box 5, and the aperture of the sieve holes of the conical filter net 401 and the rectangular filter net 402 is larger than the aperture of the sieve holes of the collection box 5.

[0030] Working principle: When draining water, the rainwater first passes through the grid plate 101. Since the thorn plate 2 is arranged below the grid plate 101, when the rainwater flows through the thorn plate 2, the thorns on the thorn plate 2 will hook the sundries in the rainwater to realize the secondary filtration of the rainwater; the blade 302 rotates under the scouring of the rainwater and drives the cleaning plate 303 to rotate. Under the action of the cleaning plate 303, the sundries on the conical filter net 401 slide down into the rectangular filter net 402; under the action of the impact of the rainwater and the elastic force of the spring 602, the filter net 4 vibrates, and during the vibration, the sundries can slide down from the conical filter net 401 into the rectangular filter net 402 again, so as to effectively improve the collection effect of the sundries and realize the third filtration of the rainwater at the same time. The collection box 5 located below the filter net 4 can filter the sundries in the rainwater again.
