[0038] During the specific implementation process, it should be noted that when the device needs to be sunk to the bottom of the water, the counterweight part is first connected to the connecting column 6. During installation, the block 8 is squeezed through the control part, and the spring 7 contracts after receiving the pressure. The block 8 contracts into the interior of the connecting column 6, and then the counterweight part is installed. After installation, the device is sunk to the bottom of the water.

[0044] During the specific implementation process, it should be noted that when the counterweight 11 needs to be installed, the groove 12 of the counterweight 11 is aligned with the connecting column 6. During installation, the spring 7 is reset by rotating the control unit, and the block 8 is reset under the action of the spring 7. The block 8 is then inserted into the interior of the socket 13.

At the same time, the driving gear 29 rotates. Since the driven gear 30 and the driving gear 29 are meshed with each other, the driven gear 30 drives the reciprocating screw 22 to start rotating, and the moving block 27 moves under the action of the reciprocating screw 22's own thread and the slide rail 26. The limiting wheel 28 starts to limit the connecting rope 10. The mounting frame 23 and the pulley 24 are used to assist in limiting the connecting rope 10 to prevent the connecting rope 10 from being worn out due to the contact with the shell 19, thereby improving the life of the connecting rope 10.
