[0002] As a common underwater pumping equipment, submersible pumps are widely used in farmland irrigation, pond drainage, urban water supply and various industrial fields. However, the controller part of the traditional submersible pump is often directly exposed to the external environment during use, which is easily affected by moisture, impurities and physical impact, thereby causing damage to the controller or performance degradation. In addition, although the remaining part of the submersible pump body is located underwater, long-term water scouring and silt accumulation may also cause damage to it, affecting the service life of the pump.
