AI Technical Summary

Technical Problem

Existing submersible pumps are prone to high sand content in rural well water and private water storage tanks due to water level fluctuations, making it difficult to avoid sediment at the bottom of the tank and affecting water quality.

Method used

A float-type submersible pump was designed. By combining an annular hollow float and a submersible pump, the depth of the submersible pump is adjusted by buoyancy balance. The buoyancy of the float is dynamically adjusted by combining an air pump and a touch switch. It is equipped with a stainless steel mesh to filter debris and a current sensor to prevent entanglement, thus achieving dynamic adjustment and protection.

Benefits of technology

It effectively maintains a fixed depth for the submersible pump amidst water level fluctuations, reduces sand content, ensures clean water quality, prevents sediment and debris from accumulating at the bottom of the pool, and lowers manufacturing costs.

Abstract

The application discloses a float submersible pump and a dynamic adjusting method thereof. The float submersible pump comprises a ring-shaped hollow float and a submersible pump. The shell of the submersible pump is connected with the ring-shaped hollow float through a support frame. The submersible pump is coaxially arranged in a central through hole of the ring-shaped hollow float. The lower end of the submersible pump body extends out of the bottom surface of the ring-shaped hollow float. The total buoyancy of the ring-shaped hollow float is greater than the sum of the weight of the submersible pump and the self weight of the ring-shaped hollow float. The application is suitable for rural well water and self water storage pool. The submersible pump can keep a fixed depth with water level fluctuation, avoid pumping the sediment at the bottom of the pool and guarantee the clean water quality.
