[0002] A high-sealing submersible pump is a specially designed submersible pump that employs multiple advanced sealing technologies to effectively prevent external liquids and solid particles from entering the pump, while also preventing leakage of the pump's internal media. Its "high sealing performance" is a key feature that distinguishes it from ordinary submersible pumps, ensuring reliability and safety under harsh, critical, or long-term stable operating conditions.

[0003] The authorized publication number "CN219509839U" describes "a high-sealing waterproof variable frequency motor submersible pump, including a pump body, several water inlet holes located at the bottom of the pump body and a water outlet connector located on the right side of the pump body, a motor housing located on the top of the pump body, a motor shaft located inside the motor housing, the lower end of the motor shaft passing downward into the pump body and having an impeller, a lower opening communicating with its internal space located at the center of the lower surface of the motor housing, an upper opening communicating with its internal space located on the upper surface of the pump body, a sealing sleeve located outside the motor shaft located between the motor housing and the pump body, and an upper sealing plate located on the upper outer wall of the sealing sleeve that fits against the lower surface of the motor housing".

[0004] The aforementioned patent achieves high sealing performance, providing a waterproof effect and effectively ensuring the service life of the submersible pump. However, when the pump is placed in water, the inlet is prone to sinking into silt, which affects the pumping process. Utility Model Content

[0005] The purpose of this invention is to provide a highly sealed submersible pump, which aims to solve the problem in the prior art where the inlet easily gets stuck in silt after being placed in water, thus affecting water pumping.

[0006] To achieve the above objectives, this utility model provides the following technical solution:
