[0025] A push rod 303 is rotatably mounted on the connecting plate 302, one end of which is rotatably connected to the L-shaped connecting hook 202. The connecting plate 302 is adapted to move linearly along with the telescopic end of the hydraulic telescopic rod 301. When the connecting plate 302 moves downward, the push rod 303 is driven downward. When the push rod 303 moves downward, the L-shaped connecting hook 202 is pushed to one side by the rotating member 304. When the L-shaped connecting hook 202 moves forward, the rotating member 201 drives the L-shaped connecting hook 202 to flip open, so that the connecting rope can be towed.

[0026] A baffle 203 is connected to one side of the inner wall of the L-shaped connecting hook 202. The baffle 203 is used to limit the connection between the connecting rope and the L-shaped connecting hook 202.

[0027] A protective assembly 4 is slidably mounted on the side of the mounting rod 1. The protective assembly 4 includes a movable rod 401 slidably mounted on the side of the mounting rod 1. Limiting plates 402 are fixedly mounted on the upper and lower surfaces of the movable rod 401. The limiting plates 402 are attached to the upper and lower surfaces of the mounting rod 1. The two sets of limiting plates 402 are suitable for limiting the movement of the movable rod 401 within the mounting rod 1.

[0028] A bolt 406 is connected to the limiting plate 402. The bolt 406 passes through the limiting plate 402, the movable rod 401 and the mounting rod 1. A nut 407 is threadedly connected to one end of the bolt 406. The bolt 406 is suitable for fixing the movable rod 401 in the mounting rod 1.

[0029] A protective cover 403 is fixedly mounted on one end of the movable rod 401. The protective cover 403 is a semi-columnar structure, and a sealing ring (not shown in the figure) is provided at the contact position between the two sets of protective covers 403.

[0032] Working principle:

[0033] During use, after the underwater robot is placed in the water, the hydraulic telescopic rod 301 is activated to drive the connecting plate 302 to move downward. When the connecting plate 302 moves downward, the pushing rod 303 is driven downward. When the pushing rod 303 moves downward, the rotating member 304 pushes the L-shaped connecting hook 202 to move to one side. When the L-shaped connecting hook 202 moves forward, the rotating member 201 drives the L-shaped connecting hook 202 to flip open, so that the connecting rope can be towed, thereby quickly removing the connecting rope connected to the underwater robot.

[0034] A connecting plate 305 with a threaded connecting rod 306, a threaded sleeve 308 and a plurality of counterweights 307 are provided on both sides of the mounting frame rod 1 so that the device can play a balancing role when operating in water;

[0035] The two sets of protective covers 403 arranged in a close relationship can protect the hydraulic telescopic rod 301, thereby preventing it from being corrosive by seawater, which makes the hydraulic cylinder prone to electrochemical corrosion in seawater, causing surface rust and peeling. At the same time, when the hydraulic telescopic rod 301 fails after long-term use, the fasteners 405, bolts 406 and nuts 407 can be loosened, and the two sets of protective covers 403 can be moved in opposite straight lines to protect the hydraulic telescopic rod 301 and facilitate disassembly and maintenance.

[0036] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
