摘要（英）：

The utility model discloses an underwater motor sealing device which includes a motor, a housing, a rotary shaft, a propeller and a baffle plate. The motor is arranged in the housing. The propeller is arranged on the outside of the housing. The motor is connected with the propeller via the rotary shaft. The inside of the housing is provided with the baffle plate. The baffle plate is arranged between the propeller and the motor. The connecting part between the rotary shaft and the motor, the connecting part between the rotary shaft and the baffle plate, and the connecting part between the rotary shaft and the housing are provided with silica gel sealing rings. The rotary shaft on the outside of the housing is provided with a coupling. The coupling is arranged between the propeller and the housing. The bottom of the baffle plate is provided with a water pump. The water pump is provided with a non-way valve, a water tube and a liquid level sensor. The underwater motor sealing device greatly improves the motor underwater operation safety and especially improves the deepwater operation safety, and is stable in performance and is long in service lifetime.
