Description
Technical Field
The invention relates to a sealing structure of an underwater propulsion motor. Belongs to the field of motor sealing.
Background
For a general existing middle-small underwater motor, the motor cable is clamped and sealed by a sealing device such as a stuffing box, so that water can be prevented from entering the motor. However, for a large underwater propulsion motor, the motor current reaches thousands of amperes, a motor cable is a three-core cable, if positive pressure gas exists in the motor, the gas can leak through gaps among the three cores, and the positive pressure cannot be maintained in the motor.
Because the environmental protection requirement, marine use propulsion motor bearing lubricating grease can not reveal in the ocean, consequently bearing lubricating grease drain all is inside the motor, needs the inside malleation that keeps of motor, just can get rid of the outside of motor with the inside dirty oil of motor through the functional pipeline. In addition, for the underwater propulsion motor, the motor can cause external water leakage to the inside of the motor, the safety of ship navigation can be influenced by internal water leakage, and the inside of the motor can be discharged out of the motor by keeping positive pressure.
Disclosure of Invention
The invention aims to provide a sealing structure suitable for an underwater propulsion motor, which is used for solving the problem of motor air leakage caused by direct extraction of a three-core cable of a high-current motor, keeping positive pressure inside the motor, discharging dirty oil and water inside the motor, and meeting the requirements of high-current input, signal extraction and functional pipeline access of the motor.
In order to meet the aim, the technical scheme of the invention is as follows: the sealing structure of the underwater propulsion motor comprises an insulating sealing plate, an insulating conductive bar, a sealing ring, an external thread pipeline, an aviation plug, a motor cable, a motor signal wire and a functional pipeline in the motor, wherein the sealing ring is arranged in a groove at the back of the insulating sealing plate and is in sealing connection with a motor supporting plate through a bolt; a square sealing ring is arranged in the groove of the insulating conductive bar and is in sealing connection with the insulating sealing plate through a bolt; the external thread pipeline is coated with sealant and then is arranged in the internal thread through hole of the insulating sealing plate, and air leakage between the external thread pipeline and the internal thread of the insulating sealing plate is prevented by the sealant; the aviation plug is installed on the insulation sealing plate through the bolt, and the sealing ring on the aviation plug prevents air leakage between the insulation sealing plate and the aviation plug.
Further, the motor cable is connected from one end of the insulated conducting bar, and the other end of the insulated conducting bar is connected out.
Further, the motor signal wire is connected from one end of an aviation plug mounted on the insulating sealing plate, and the other end of the motor signal wire is connected out.
Further, the functional pipeline in the motor is connected with an internal thread pipeline arranged on the insulating sealing plate.
Further, the motor cable, the signal wire and the functional pipeline are intensively led out through the insulating sealing plate, air pressure is added into the motor through the functional pipeline, positive pressure in the motor can be kept, and water and oil leaked into the motor are discharged through the functional pipeline.
The invention has the beneficial effects that:
install motor lead-out cable on this seal structure's insulating busbar, connect signal line on this seal structure's aviation plug, connect the functional pipeline on this seal structure's external screw thread pipeline, add atmospheric pressure to the motor inside through the functional pipeline, the motor inside can keep the malleation, solve the inside atmospheric pressure of motor and follow the condition that the motor cable leaked gas, satisfied the motor inside requirement that keeps the malleation, satisfied the requirement that the motor was inserted to the heavy current of motor, signal access, functional pipeline inserted simultaneously.
