[0002] Photovoltaic booster stations are specially designed for photovoltaic power generation systems. They are used to boost the low voltage generated by photovoltaic power generation systems to a high voltage suitable for long-distance power transmission. In order to protect the cables and facilitate cable maintenance, a cable well is usually opened near the photovoltaic booster station. When the cables need to be repaired, workers only need to open the well cover and enter the well to carry out maintenance work. The cable well will also have poor drainage after long-term use, resulting in water accumulation in the cable well. Workers need to go to the cable well and use a water pump to drain the water in the cable well.

[0003] The water pump is composed of a pump head and a motor. The motor is fixedly connected to the outside of the pump body. The output shaft of the motor penetrates into the pump body and is fixedly connected to the impeller. The output shaft of the motor drives the impeller to rotate, allowing the pump body to pump water.
