[0024] The cleaning mechanism 5 includes a rotating plate 501, the number of which is two. One side of the rotating plate 501 is rotatably connected to one side of the first filter plate 3, and one side of the rotating plate 501 is rotatably connected to one side of the second filter plate 4. A brush plate 502 is fixedly connected to one side of the rotating plate 501. The surface of the brush plate 502 is attached to the surface of the first filter plate 3, and the surface of the brush plate 502 is attached to the surface of the second filter plate 4. One side of the rotating plate 501 is fixedly connected to a connecting shaft 503. One end of the connecting shaft 503 is fixedly connected to one side of the rotating plate 501. The connecting pipe 1 in the rainwater drainage pipe with the filter screen is connected by The flange 2 is connected to the external pipeline, and rainwater and the mud and debris it carries enter through one end of the connecting pipe 1. The mesh of the first filter plate 3 is larger than the mesh of the second filter plate 4, so that the rainwater is filtered layer by layer through the first filter plate 3 and the second filter plate 4. After a long period of filtration, a group of rotating plates 501 in the cleaning mechanism 5 rotates, and at the same time drives another group of rotating plates 501 to rotate through the connecting shaft 503. When the rotating plate 501 rotates, it can drive the brush plate 502 to brush off the mud or impurities remaining on the surface of the first filter plate 3 and the second filter plate 4, thereby ensuring the filtering effect of the first filter plate 3 and the second filter plate 4.

[0025] Reference Figure 2 A first motor 6 is fixedly installed on the surface of the connecting pipe 1, and a driving wheel 7 is fixedly connected to the output end of the first motor 6. A driven wheel 8 is fixedly connected to one side of the rotating plate 501. The surface of the driven wheel 8 and the surface of the driving wheel 7 are connected by a transmission belt 9. Through the setting of the first motor 6, the first motor 6 can drive the driving wheel 7 at the output end to rotate. When the driving wheel 7 rotates, it drives the transmission belt 9 to rotate. When the transmission belt 9 rotates, it drives the driven wheel 8 at the other end to rotate. When the driven wheel 8 rotates, it drives the corresponding connected rotating plate 501 to rotate, thereby realizing the synchronous rotation of the two sets of rotating plates 501.

[0026] Reference Figure 1 and Figure 3 A protective shell 10 is fixedly connected to the surface of the connecting pipe 1, a sealing plate 11 is fixedly inserted on one side of the protective shell 10, a heat dissipation groove 12 is opened on one side of the protective shell 10, and the first motor 6 is arranged in the inner cavity of the protective shell 10. Through the setting of the protective shell 10, the protective shell 10 and the sealing plate 11 cooperate to provide sealing protection for the first motor 6, thereby extending the service life of the first motor 6. The heat dissipation groove 12 can ensure that the first motor 6 dissipates heat during continuous operation.

[0027] Reference Figure 1The surface of the connecting pipe 1 is fixedly connected to a material guide shell 13, the inner cavity of the material guide shell 13 is provided with a crushing mechanism 16, one side of the material guide shell 13 is fixedly connected to a storage box 14, and the bottom of the storage box 14 is fixedly connected to a fixed plate 15. Through the provided storage box 14, the connecting pipe 1 and the material guide shell 13 are connected, and the mud and sand impurities removed by the cleaning mechanism 5 will enter the storage box 14 through the material guide shell 13, and the accumulation of mud and sand impurities inside the connecting pipe 1 can be avoided as much as possible. The fixed plate 15 can improve the overall stability.

[0028] Reference Figure 4 The crushing mechanism 16 includes a first crushing roller 1601 and a second crushing roller 1602, one end of which is rotatably connected to the inner wall of the guide shell 13, one end of the first crushing roller 1601 is fixedly connected to a first gear 1603, and one end of the second crushing roller 1602 is fixedly connected to a second gear 1604, and the teeth of the second gear 1604 and the first gear 1603 are meshed with each other. A second motor 17 is fixedly installed on one side of the guide shell 13, and the output end of the second motor 17 is fixedly connected to one end of the first crushing roller 1601. Through the provided crushing mechanism 16, when mud and sand impurities pass through the guide shell 13, the first crushing roller 1601 and the first gear 1603 can be driven to rotate by the second motor 17. Since the teeth of the first gear 1603 and the second gear 1604 are meshed with each other, the rotation of the first crushing roller 1601 drives the second crushing roller 1602 to achieve relative rotation, thereby crushing larger impurities, thereby facilitating storage.

[0029] Working principle: the connecting pipe 1 is connected to the external pipe through the connecting flange 2, and rainwater and the mud and debris it carries enter through one end of the connecting pipe 1. The mesh of the first filter plate 3 is larger than the mesh of the second filter plate 4, so that the rainwater is filtered layer by layer through the first filter plate 3 and the second filter plate 4. The first motor 6 is activated to drive the driving wheel 7 at the output end to rotate. The driving wheel 7 rotates while driving the transmission belt 9 to rotate. The transmission belt 9 rotates while driving the driven wheel 8 at the other end to rotate. The driven wheel 8 rotates while driving the corresponding connected rotating plate 501 to rotate, thereby realizing the synchronous rotation of the two sets of rotating plates 501. When the rotating plate 501 rotates, it can drive the brush plate 502 to the first The silt or impurities remaining on the surfaces of the first filter plate 3 and the second filter plate 4 are brushed off, thereby ensuring the filtering effect of the first filter plate 3 and the second filter plate 4. The connecting pipe 1 is connected to the material guide shell 13. The silt and impurities removed by the cleaning mechanism 5 will enter the storage box 14 through the material guide shell 13, and the accumulation of silt and impurities inside the connecting pipe 1 is avoided as much as possible.
