Technical Field

[0001] This utility model belongs to the field of submersible pumps, and relates to a submersible pump, and particularly to an anti-clogging submersible pump. Background Technology

[0002] A submersible pump is a device with a sealed motor tightly coupled to the pump body. The entire assembly is submerged in the fluid to be pumped. Submersible pumps are used in many applications. Single-stage pumps are used for drainage, sewage pumping, general industrial pumping, and slurry pumping.

[0003] To prevent sediment, weeds, and other debris from accumulating outside the filter cover, existing submersible pumps have a filter cover placed at the pump inlet. However, after prolonged use, sediment, weeds, and other impurities in the water flow often adhere to the filter cover, reducing the water flow through it. This leads to increased motor load, a risk of burnout, and a reduced lifespan of the submersible pump.

[0004] For example, a new type of submersible pump with application number 202121737950.4 includes a pump body, a pump shaft, an impeller and a water inlet. The pump body is equipped with a filter unit, the water inlet is located inside the filter unit, the filter unit and the pump body are connected by a locking mechanism, and the pump body is also provided with an auxiliary support structure and an anti-detachment water connector.

[0005] The aforementioned patent connects the pump body and the filter unit through a locking mechanism, which facilitates the disassembly and replacement of the filter unit. However, the filter unit is easily clogged by impurities such as mud, sand, and aquatic plants during use, causing the submersible pump to have difficulty pumping water and eventually burn out.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 3 As shown, this utility model can be implemented through the following embodiment: A clog-resistant submersible pump includes a pump body 1, a motor 2, and a filter cover 3. A rotating shaft 21 is installed inside the motor 2, and a mounting shaft 4 is fixedly connected to the rotating shaft 21. An inlet 11 is opened at the bottom of the pump body 1, and a mounting part 111 is provided on the outside of the inlet 11. The filter cover 3 is connected to the mounting part 111. A column 12 extends from the lower end face of the pump body 1. A support plate 5 is installed on the column 12. A sliding groove 51 is opened on the support plate 5. A base 31 corresponding to the sliding groove 51 is opened on the filter cover 3. An mounting groove 52 is opened between the columns 12 on the support plate 5. A fixing part 13 is provided on the lower end face of the pump body 1. A brush 6 is installed between the mounting groove 52 and the fixing part 13.

[0021] The filter cover 3 rotates synchronously with the mounting shaft 4. The mounting part 111 restricts the upper space of the filter cover 3 and guides the movement of the filter cover 3. A support plate 5 is installed on the column 12. The support plate 5 connects with the base plate 7 on the filter cover 3 through the sliding groove 51 and restricts the displacement of the filter cover 3, so that the filter cover 3 is in close contact with the mounting part 111. The base 31 rotates along the sliding groove 51 to prevent there from being too large a gap between the filter cover 3 and the inlet 11, which would prevent the filter cover 3 from filtering the water entering the pump body 1. A brush 6 is installed between the mounting groove 52 and the fixing part 13. Through the rotation of the filter cover 3 itself, the brush 6 brushes away the impurities on the filter cover 3.

[0022] like Figure 2 As shown, a positioning block 41 is provided on the mounting shaft 4, and a positioning groove 311 is provided on the base 31. The positioning block 41 and the positioning groove 311 cooperate to connect the filter cover 3 and the mounting shaft 4, so that the mounting shaft 4 and the filter cover 3 can rotate synchronously.

[0023] like Figure 1 and Figure 2 As shown, a connecting rod 121 extends from the column 12, passing through the support plate 5. The connecting rod 121 is connected to the base plate 7, and the base plate 7 is connected to the connecting rod 121 by bolts 8. A step is formed between the connecting rod 121 and the column 12. The support plate 5 abuts against the step and is limited by the base plate 7. The base plate 7 is fixed to the connecting column by bolts 8, thereby fixing the base plate 7 to the pump body 1 and fixing the support plate 5. By fixing the support plate 5, the displacement of the filter cover 3 is restricted, preventing the filter cover 3 from detaching from the pump body 1.

[0024] like Figure 2 and Figure 3As shown, an annular groove 511 is formed in the sliding groove 51, and steel balls are embedded in the base 31. The annular groove 511 and the steel balls cooperate to make a part of the base 31 contact the sliding groove 51 through the steel balls, changing the sliding friction into rolling friction, reducing the friction between the base 31 and the sliding groove 51, and reducing the load on the rotating shaft 21.

[0025] like Figure 1 and Figure 2 As shown, the brush 6 consists of a frame 61 and a bristle plate 62. The frame 61 is equipped with a mounting block 611 and a fixing block 612. The mounting block 611 has a slot 611a, and a short rod 521 is installed within the mounting slot 52. The frame 61 is used to mount the bristle plate 62, and the brush 6 is fixed to the pump body 1 by connecting the mounting block 611 and the fixing block 612 on the frame 61 to the mounting slot 52 and the fixing part 13, respectively. The mounting block 611 has a slot 611a that clamps the short rod 521 within the mounting slot 52. The short rod 521 is designed so that the brush 6 can rotate with the short rod 521. When the brush 6 cleans the filter cover 3, the reaction force on the brush 6 is in the same direction as the opening of the slot 611a, preventing the slot 611a from disengaging from the short rod 521.

[0026] like Figure 1 and Figure 2 As shown, a bracket 9 is provided on the right side of the fixing part 13, a pull rod 91 is installed on the bracket 9, and a locking block 911 is provided at the end of the pull rod 91. A spring 10 is provided between the locking block 911 and the bracket 9. A corresponding groove 612a is provided on the fixing block 612. The locking block 911 cooperates with the groove 612a to limit the displacement of the fixing block 612, preventing the brush 6 from falling off due to the rotation of the water pump during operation, which would prevent the brush 6 from cleaning the filter cover 3 properly. The pull rod 91 is used by the user to move the locking block 911 to provide space for the installation of the brush 6. The spring 10 is used to reset the locking block 911, so that the locking block 911 is kept in the groove 612a, and the brush 6 is fixed to the fixing part 13.

[0027] like Figure 2 As shown, a second spring 621 is installed on the brush plate 62, and a fixing plate 622 is connected to the second spring 621. The fixing plate 622 is fixed inside the frame 61. The brush plate 62 is connected to the frame 61 through the second spring 621, so that the brush plate 62 is pushed by the second spring 621 to fit tightly against the filter cover 3, thereby improving cleaning efficiency.
