Abstract

The invention discloses a motor for underwater work, which comprises a shell. A stator and a rotor are arranged in the shell; an output shaft is inserted into the rotor; the output shaft is rotationally connected to the inner side wall of the stator; one end of the stator penetrates through the side wall of the shell through a bearing; vertical strip-shaped cavities are symmetrically formed in theside wall of one end of the shell; a one-way valve is installed at the end, close to the output shaft, of each strip-shaped cavity; a heat conduction column is fixedly connected to the end, away fromthe output shaft, of each strip-shaped cavity; a pressure valve is further installed on one side of each heat conduction column; and the pressure valves are located in the stators. Through interaction of structures such as an airflow ring, the pressure valve, the one-way valve and the heat conduction column, the water solution can be changed into gas to be sprayed out from slits, and the water solution in the slits can be discharged out of the shell along the air flow, so that water cannot flow into the shell along the slits, the motor is well protected, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a motor for underwater work. Background technique [0002] For submersible motors, that is, motors for underwater operation, the main technical requirement is good waterproof performance; for this reason, the current submersible motors use a fully enclosed casing, and waterproof bearings are used to frame the shaft on the casing; Due to technological limitations, the waterproof performance of the waterproof shaft is always limited. In deep water areas, water may still seep into the motor from various gaps in the waterproof shaft, thereby causing damage to the motor. In view of this reason, in order to increase the diving depth, the current submersible motor mainly adopts the method of improving the sealing performance of the waterproof rotating shaft as much as possible. The closer the sealing ring and the movable gap of the bearing are in contact, the better the water...
