Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-4, a circulating water pump with a filtering mechanism in this embodiment includes a circulating water pump 1. A water outlet pipe 2 is bolted to the right side of the circulating water pump 1, and a filtering component for filtering impurities in the water body is arranged on the left side of the circulating water pump 1. The filtering component includes a water inlet pipe 3 bolted to the left side of the circulating water pump 1, a filter plate 4 fixedly connected to the right side inner wall of the water inlet pipe 3, and a filtering and cleaning mechanism arranged inside the water inlet pipe 3. The filtering and cleaning mechanism includes a support plate 5 fixedly connected to the left side inner wall of the water inlet pipe 3, a connecting plate 6 fixedly connected to the right side of the support plate 5, a sleeve 16 slidably sleeved on the outer side of the connecting plate 6, a connecting block 18 fixedly connected to the upper side of the sleeve 16, a straight tooth plate 14 fixedly connected to the right side of the connecting block 18, a gear 15 meshed with the front end surface of the straight tooth plate 14, a first rotating shaft 7 fixedly sleeved on the inner wall of the gear 15, a first bevel gear 13 fixedly sleeved on the lower side outer wall of the first rotating shaft 7, a second bevel gear 19 meshed with the lower side of the first bevel gear 13, a second rotating shaft 8 fixedly sleeved on the inner wall of the second bevel gear 19, a cleaning brush 9 fixedly connected to the right side of the second rotating shaft 8, and a spring telescopic rod 12 fixedly connected to the right side of the sleeve 16.

[0027] Among them, a limiting component for limiting the spring telescopic rod 12 is arranged on the right side of the spring telescopic rod 12. The limiting component includes a limiting plate 11 fixedly connected to the right side of the spring telescopic rod 12. A rotating component for rotating the second bevel gear 19 is arranged on the left side of the second bevel gear 19. The rotating component includes a bearing 10 fixedly sleeved on the inner wall of the second bevel gear 19. The top of the first rotating shaft 7 is rotatably sleeved on the inner top wall surface of the water inlet pipe 3. The side of the cleaning brush 9 away from the second rotating shaft 8 is attached to the left side surface of the filter plate 4. The water inlet end of the circulating water pump 1 is communicated with the water inlet pipe 3, and the water drainage end of the circulating water pump 1 is communicated with the water outlet pipe 2. Both the support plate 5 and the filter plate 4 are vertically fixedly connected to the inner wall surface of the water inlet pipe 3. The support plate 5 and the connecting block 18 are in a horizontally parallel structure. The straight tooth plate 14 is vertically fixedly connected to the right side surface of the connecting block 18.

[0028] Embodiment Two:

[0029] Please refer to Figure 1 and Figure 3 , on the basis of Embodiment One, it includes convex plates 17 respectively fixedly connected to the left and right sides of the sleeve 16, and the two convex plates 17 are arranged horizontally.

[0030] Adopting the above technical solution, when the water flow is flowing, the impact of the water flow collides with the surface of the convex plate 17 and pushes the sleeve 16 to slide on one side of the connecting plate 6 in the direction of the water flow.

[0031] The working principle of the above embodiment is:

[0032] The water outlet pipe 2 and the water inlet pipe 3 are respectively fixedly connected by bolts. When the water flow generates an impact force while flowing in the water inlet pipe 3, it pushes the convex plate 17 on the outer side of the sleeve 16 and slides towards the side of the circulating water pump 1. The straight tooth plate 14 connected to the connecting block 18 on the upper side of the sleeve 16 meshes with the gear 15 to rotate the first bevel gear 13 on the lower side of the first rotating shaft 7 and meshes with the bearing 10 to rotate. The bearing 10 then drives the cleaning brush 9 connected by the second rotating shaft 8 to rotate on the surface of the filter plate 4 to clean the filtered impurities, avoiding the situation of impurities clogging in the filter plate 4. When the circulating water pump 1 is not in use and the water flow stops, the spring telescopic rod 12 rebounds to make the straight tooth plate 14 mesh with the gear 15 again to rotate the first bevel gear 13 in the reverse direction, and the cleaning brush 9 connected to the second rotating shaft 8 rotates synchronously in the reverse direction on the surface of the filter plate 4 to clean the impurities on the surface of the filter plate 4 again.
