However, because they cannot remove weeds and foreign objects adsorbed at the water inlet in time, they will cause blockage at the water inlet and reduce the water output flow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter anti-clogging device for a municipal submersible pump, comprising a pump body and an anti-clogging mechanism, wherein a stainless steel filter cylinder is fixedly installed at the inlet of the pump body by bolts, the anti-clogging mechanism is installed at the lower end of the stainless steel filter cylinder, the anti-clogging mechanism is configured to cooperate with the outer arc surface of the stainless steel filter cylinder, and the pump body is electrically connected to an external control switch.

[0006] In order to ensure that water can always enter the pump body at the maximum flow rate, as a preferred embodiment of the filter anti-clogging device for municipal submersible pumps of this utility model, the anti-clogging mechanism includes a rotating plate and a scraper. The end of the rotating plate is rotatably connected to the middle of the bottom of the stainless steel filter cylinder via a rotating shaft. The end of the rotating plate away from the center of the stainless steel filter cylinder is equipped with a scraper via a connecting rod.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a pump body 1 and an anti-clogging mechanism 3.

[0019] In this technical solution, a filter anti-clogging device for a municipal submersible pump is provided. A stainless steel filter cylinder 2 is fixedly installed at the inlet of the pump body 1 by bolts. An anti-clogging mechanism 3 is installed at the lower end of the stainless steel filter cylinder 2. The anti-clogging mechanism 3 is configured to cooperate with the outer arc surface of the stainless steel filter cylinder 2. The pump body 1 is electrically connected to an external control switch.

[0020] In this technical solution, the staff first place the pump body 1 and its auxiliary mechanisms into the water body within the municipal area, and regulate the operation of the pump body 1 through an external control switch. At this time, the pump body 1 pumps and transports the water. During this process, the stainless steel filter cylinder 2 filters the water entering the pump body 1, thereby filtering out weeds or foreign objects in the water. At the same time, the anti-clogging mechanism 3 prevents the municipal submersible pump from getting blocked during operation.

[0021] In some technical solutions, reference Figure 1-4 The anti-clogging mechanism 3 includes a rotating plate 31 and a scraper 32. The end of the rotating plate 31 is rotatably connected to the middle of the bottom of the stainless steel filter cylinder 2 via a rotating shaft. The end of the rotating plate 31 away from the center of the stainless steel filter cylinder 2 is equipped with a scraper 32 via a connecting rod. The scraper 32 is in close contact with the outer wall of the stainless steel filter cylinder 2.

[0022] In this technical solution, the scraper 32 removes weeds and foreign objects adsorbed on the stainless steel filter cylinder 2 while rotating, so that water can always enter the pump body 1 at the maximum flow rate.

[0023] In some technical solutions, reference Figure 3-4 The anti-clogging mechanism 3 also includes a waterproof motor 33, which is located in the inner cavity of the stainless steel filter cylinder 2 and is fixed to the bottom of the inner cavity of the stainless steel filter cylinder 2 by bolts. The output end of the waterproof motor 33 is keyed to the rotating plate 31, and the electrical input of the waterproof motor 33 is connected to an external control switch.

[0024] In this technical solution, the staff controls the waterproof motor 33 through an external control switch. The output shaft of the waterproof motor 33 rotates, driving the rotating plate 31 and the scraper 32 to rotate synchronously, thus achieving a highly efficient driving effect.

[0025] In some technical solutions, reference Figure 1-4 A rotating roller 4 is rotatably connected to the top surface of the end of the rotating plate 31 away from the center of the stainless steel filter cylinder 2. Brush bristles 5 are evenly inserted into the outer wall of the rotating roller 4, and the ends of the brush bristles 5 can contact the outer wall of the stainless steel filter cylinder 2.

[0026] In this technical solution, the rotating roller 4 and the brush 5 rotate to clean the outer arc surface of the stainless steel filter cylinder 2, preventing the stainless steel filter cylinder 2 from being blocked by weeds and foreign objects, which would reduce the flow rate and allow the municipal submersible pump to always be in a high-efficiency working state.

[0027] In some technical solutions, reference Figure 2-4 A rotating gear 6 is sleeved on the outer wall of the bottom end of the rotating roller 4, and a fixed gear ring 7 is sleeved on the outer wall of the bottom of the stainless steel filter cylinder 2. The fixed gear ring 7 is meshed with the rotating gear 6.

[0028] In this technical solution, at the same time, the rotating gear 6, while revolving around the sun, drives the rotating roller 4 and the brush bristles 5 to rotate through the fixed gear ring 7, thus achieving rapid transmission.

[0029] In some technical solutions, reference Figure 1 The lower end of the outer arc surface of the stainless steel filter cylinder 2 is rotatably connected to a rotating protective cover 8 via a bearing 2. The rotating gear 6 and the fixed gear ring 7 are both located inside the rotating protective cover 8. The upper end of the rotating protective cover 8 has through openings corresponding to the scraper 32 and the rotating roller 4.

[0030] In this technical solution, the rotating protective cover 8 serves to protect the internal mechanism.

[0031] Working Principle: First, the operator places the pump body 1 and its auxiliary mechanisms into the water body within the municipal area. The operation of pump body 1 is then controlled via an external switch. Pump body 1 then pumps and transports water. During this process, the stainless steel filter cartridge 2 filters the water entering pump body 1, removing weeds or foreign objects to prevent blockages. Simultaneously, the operator controls the waterproof motor 33 via the external switch. The output shaft of the waterproof motor 33 rotates, driving the rotating plate 31, scraper 32, rotating roller 4, brush 5, and... The rotating gear 6 rotates synchronously, and the scraper 32 removes weeds and foreign objects adsorbed on the stainless steel filter cylinder 2 while rotating, so that the water can always enter the pump body 1 at the maximum flow rate. At the same time, the rotating gear 6 rotates around the central axis and drives the rotating roller 4 and brush 5 to rotate through the fixed gear ring 7, thereby cleaning the outer arc surface of the stainless steel filter cylinder 2 and preventing the stainless steel filter cylinder 2 from being blocked by weeds and foreign objects, which would reduce the flow rate. This allows the municipal submersible pump to always be in a high-efficiency working state. The rotating protective cover 8 plays a role in protecting its internal mechanism.
