[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution for a submersible pump body structure that can clear blockages: it includes a rotating shaft 1, an impeller 2 connected to the outer wall of the rotating shaft 1, a pump chamber 3 disposed outside the impeller 2, and the interior of the pump chamber 3 rotatably connected to the outer wall of the rotating shaft 1. Several first toothed blocks 4 are connected to the outer wall of the impeller 2. The core function of the first toothed blocks 4 is to cooperate with the second toothed blocks 5 on the inner wall of the pump chamber 3. When the rotating shaft 1 drives the impeller 2 to rotate, it shears and breaks up residual impurities that have not been completely filtered by the filter screen 7 in real time, preventing impurities from accumulating in the flow channel of the pump chamber 3 or at the impeller 2, thus preventing blockages from the source inside the pump body. To ensure the smooth operation of the submersible pump, several second toothed blocks 5 are connected to the inner wall of the pump chamber 3. A bottom cover 6 is provided on the bottom surface of the pump chamber 3, and a filter screen 7 is connected to the bottom surface of the bottom cover 6. The bottom end of the rotating shaft 1 passes through the bottom cover 6 and the filter screen 7 in sequence and is connected to a brush plate 8. The upper surface of the brush plate 8 is in contact with the bottom surface of the filter screen 7. The brush plate 8 rotates synchronously with the rotating shaft 1. Its contact design with the bottom surface of the filter screen 7 can continuously scrape off the impurities attached to the filter screen 7, prevent the pores of the filter screen 7 from being blocked, and ensure that the liquid can smoothly pass through the filter screen 7 into the pump chamber 3, maintaining a stable suction flow of the submersible pump.

[0019] The outer wall of the pump chamber 3 is connected to a connecting ring 9, and a sealing groove 10 is provided on the bottom surface of the connecting ring 9. The upper surface of the bottom cover 6 is provided with a sealing ring 11 that matches the sealing groove 10. The connecting ring 9 is movably connected to the bottom cover 6 by bolts. The sealing ring 11 is precisely matched with the sealing groove 10 on the bottom surface of the connecting ring 9 on the outer wall of the pump chamber 3, sealing the connection between the pump chamber 3 and the bottom cover 6, preventing liquid from seeping in or leaking from the gap, and ensuring that external liquid can only enter the pump chamber 3 through the connecting pipe 13 and the filter screen 7, thus ensuring the sealing performance of the submersible pump and the uniqueness of the water flow path. The outer wall of the rotating shaft 1 is connected to two limiting rings 12, and the side of the two limiting rings 12 that are close to each other is in contact with the outer surface of the impeller 2.

[0020] The bottom cover 6 is connected to a connecting pipe 13, and the bottom end of the connecting pipe 13 is connected to a first flange 14. The first flange 14 serves as the connection interface at the bottom end of the connecting pipe 13. The overall length of the connecting pipe 13 can be extended by connecting an extension pipe or other compatible fittings to meet the requirements of deep liquid level extraction. The outer wall of the connecting pipe 13 is connected to a base 15, and the bottom surface of the base 15 has multiple fixing holes 16.

[0021] The upper surface of the pump chamber 3 is connected to a sealing chamber 17, which seals and protects the rotating shaft 1 that passes through it, isolates the liquid inside the pump chamber 3 from the connecting cylinder 18, motor 24 and other components above, prevents liquid leakage into the power transmission area, protects the safe operation of the motor 24 and related transmission structures, and ensures the sealing reliability of the submersible pump. The outer wall of the rotating shaft 1 passes through the interior of the sealing chamber 17, and the upper surface of the sealing chamber 17 is connected to the connecting cylinder 18, which is located outside the rotating shaft 1.

[0022] The pump chamber 3 has an outlet pipe 19 connected to its output end. The end of the outlet pipe 19 away from the pump chamber 3 is connected to a second flange 22. The outer wall of the connecting cylinder 18 is connected to a connecting plate 20. The right side wall of the connecting plate 20 is connected to a fixing ring 21. The inner wall of the fixing ring 21 is connected to the outer wall of the outlet pipe 19. The fixing ring 21 and the connecting plate 20 cooperate to fit and fix the outlet pipe 19 to the outer wall, forming a stable support for the outlet pipe 19, limiting its displacement and vibration, improving the structural stability of the connection between the outlet pipe 19 and the pump chamber 3, and ensuring the installation firmness of the outlet pipe 19 during liquid transportation. The top of the connecting cylinder 18 is connected to a mounting plate 23. A motor 24 is mounted on the mounting plate 23. The output end of the motor 24 passes through the mounting plate 23 and is connected to the top of the rotating shaft 1. The side wall of the motor 24 is connected to a junction box 25.

[0023] The working principle of this utility model is as follows: First, the entire device is securely installed in the designated working position using the base 15. Then, it is connected to the external conveying pipeline through the second flange 22 at the end of the outlet pipe 19 to achieve the connection of the liquid conveying path. Next, the external power supply is connected through the junction box 25 to power the motor 24. After the motor 24 is started, its output end drives the rotating shaft 1 to rotate synchronously. The two limiting rings 12 on the outer wall of the rotating shaft 1 restrict the axial displacement of the impeller 2, ensuring that the impeller 2 rotates stably with the rotating shaft 1. The rotating shaft 1 drives the impeller 2 to rotate in the pump chamber 3, generating negative pressure suction, which draws the external liquid in through the connecting pipe 13 and the first flange 14. The liquid is first initially filtered by the filter screen 7 on the bottom surface of the bottom cover 6 to intercept large particles of impurities. When the impeller 2 rotates, several first tooth blocks 4 on its outer wall cooperate with several second tooth blocks 5 on the inner wall of the pump chamber 3 to shear and crush the residual impurities that have not been completely filtered by the filter screen 7 in real time. To prevent impurities from accumulating and clogging in the flow channel of pump chamber 3 or impeller 2, the brush plate 8 at the bottom of the rotating shaft 1 rotates synchronously with the shaft. The upper surface of the brush plate 8 contacts the bottom surface of the filter screen 7, continuously scraping away impurities attached to the filter screen 7 to prevent clogging of the filter screen pores and ensure smooth liquid entry into pump chamber 3. The connecting ring 9 on the outer wall of pump chamber 3 is fixed to the bottom cover 6 by bolts. The sealing groove 10 on the bottom surface of the connecting ring 9 is adapted to the sealing ring 11 on the upper surface of the bottom cover 6 to achieve a seal between pump chamber 3 and bottom cover 6. The rotating shaft 1 passes through the sealing chamber 17, which isolates the liquid and protects the sealing performance of the rotating shaft 1. The connecting plate 20 on the outer wall of the connecting cylinder 18 cooperates with the fixing ring 21 to fix and support the outlet pipe 19, improving the installation stability of the outlet pipe 19. The liquid pressurized by impeller 2 is transported to the external connecting pipeline through the outlet pipe 19 at the output end of pump chamber 3 and the second flange 22, completing the entire water pumping and transportation process.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
