[0023] In this embodiment, coupling magnetic blocks are fixedly installed on the periphery of the active magnetic sleeve 6 and the inner ring of the passive magnetic sleeve 8. The inner ring diameter of the passive magnetic sleeve 8 is larger than the outer ring diameter of the sealing cover 7. Through the coupling magnetic blocks in the active magnetic sleeve 6 and the passive magnetic sleeve 8, the passive magnetic sleeve 8 and the active magnetic sleeve 6 rotate synchronously for transmission.

[0024] In this embodiment, a plurality of balls 11 are installed in a ring shape. The balls 11 are located between the passive magnetic sleeve 8 and the sealing sleeve 5 and are rotatably arranged through guide rails. The passive magnetic sleeve 8 is supported and rotated by the balls 11 to reduce shaking during rotation.

[0025] In this embodiment, the rotating shaft 9 is fixedly connected to the passive magnetic sleeve 8, and the sealing cover 13 is threadedly connected in the drain hole 12. The sealing cover 13 is connected to the drain hole 12 to be opened or closed, and the water entering the sealing sleeve 5 is discharged through the drain hole 12.

[0026] In this embodiment, a connecting component 3 is installed on the top of the motor body 1, and the connecting component 3 includes a connecting seat 14 and a connecting head 15. The connecting seat 14 is fixedly installed on the top of the motor body 1, and a retaining ring 16 is fixedly installed on the periphery of the connecting seat 14.

The clamping ring 16 prevents the knob 17 from being separated from the connection seat 14, so that the knob 17 can be rotated while being connected.

[0028] In this embodiment, the outer periphery of the connector 15 is provided with threads, and the connector 15 is located in the connecting sleeve 18 and is threadedly connected. The connecting sleeve 18 rotates and is connected to the connector 15 under the action of the threads, thereby improving the seal between the connector 15 and the connecting seat 14.

[0029] It should be noted that the utility model is a motor for underwater working machinery. When in use, a power cord of a specified length is connected to the motor body 1 to provide power, so that the motor body 1 drives the rotating shaft 9 to rotate and drives the underwater working machinery; when connecting and sealing, the connector 15 of the power cord of corresponding length is plugged into the connecting seat 14, and the knob 17 is rotated to rotate the connecting sleeve 18, and the connecting sleeve 18 is connected to the connector 15 under the action of the thread, and the connector 15 is gradually slid downward to fit and seal with the connecting seat 14; when the underwater working machinery is transmitted, the output shaft 4 of the motor body 1 drives the active magnetic sleeve 6 to rotate, and the sealing cover 7 is fixed to the front part of the motor body 1, and the output shaft 4 and the active magnetic sleeve 6 are surrounded inside to seal.

When the active magnetic sleeve 6 rotates, the passive magnetic sleeve 8 is driven to rotate synchronously by the coupling magnetic block. The passive magnetic sleeve 8 is supported and rotated by the ball 11. The passive magnetic sleeve 8 drives the rotating shaft 9 to rotate for transmission. There is a gap between the rotating part of the rotating shaft 9 and the sealing sleeve 5. After long-term use, external water enters the sealing sleeve 5 through the gap. The water is isolated by the sealing cover 7 to prevent it from entering the inside of the motor body 1 through the output shaft 4. The passive magnetic sleeve 8 is waterproofed by the waterproof coating 10. The sealing cover 13 is connected to the drain hole 12, and the drain hole 12 is opened to regularly clean and discharge the entered water.
