Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to an anti-clogging self-cleaning water pump. Background Technology

[0002] Water pumps have wide applications in many fields, such as farmland irrigation, urban water supply and drainage, and industrial water transportation. However, in actual use, water pumps often face the problem of clogging. Impurities in the water, such as silt, aquatic plants, and debris, easily accumulate at the pump's inlet, impeller, and internal flow channels. When these impurities accumulate to a certain extent, they can affect the normal operation of the pump, leading to reduced flow rate, decreased head, and even motor overload and damage. Therefore, a water pump with anti-clogging function is needed.

[0003] In the prior art, utility model patent CN202322808152.1 discloses a self-cleaning water pump, including a water module and a cleaning module. The pumping module includes a movable base plate, a water pump body connected to the top of the movable base plate, two hoses connected and communicating with the water pump body, a pumping pipe connected to the outer end of the hoses, a T-shaped support plate connected to the top of the movable base plate, a movable plate movably connected between the pumping pipe and the T-shaped support plate, a tension spring connected between the T-shaped support plate and the movable plate, a circular plate installed on the outside of the movable plate, and a miniature cylinder connected to the T-shaped support plate. In this utility model, when the pumping pipe is blocked, a second electric push rod causes a scraper to reciprocate up and down through the T-shaped plate. The scraper rubs against the outer end of the blocked pumping pipe, and the pumping pipe, limited by the tension spring, vibrates continuously after friction, thereby quickly cleaning the pumping pipe, eliminating the need for manual cleaning and reducing cleaning costs.

[0004] The aforementioned patent describes a water pump with a self-cleaning function. This device uses a scraper to rub against the blocked outer end of the water pipe, and the water pipe, limited by a tension spring, vibrates continuously after friction, thus quickly cleaning the water pipe. However, this device uses vibration to prevent debris from getting stuck in a section of the water pipe, allowing it to flow out with the water flow. Instead of intercepting and expelling debris at the inlet pipe, the debris flows through the impeller, causing resistance to its rotation. This can easily lead to motor overload, and in severe cases, debris may become entangled on the impeller, causing it to jam or even damage the motor. Further improvements are needed. Utility Model Content

Instead of intercepting and discharging debris in advance at the inlet pipe, the debris will flow through the impeller, causing the impeller's rotation to encounter some resistance, which can easily lead to motor overload. In severe cases, debris may become entangled on the impeller, causing it to jam and even damaging the motor.
