[0036] The traction assembly 12 includes a traction seat 121 and two connecting rods 122. The traction seat 121 is located directly above the fixed rod 111. The two connecting rods 122 correspond to the two telescopic tubes 112 one by one. The connecting rod 122 is obliquely arranged between the traction seat 121 and the telescopic tube 112. One end of the connecting rod 122 is hinged to the traction seat 121, and the other end of the connecting rod 122 is hinged to the telescopic tube 112.

[0037] The fixing rod 111 is provided with a slide groove 118, and the slide groove 118 extends to both ends of the fixing rod 111. The inner wall of the telescopic tube 112 is provided with a clamping strip 119, and the clamping strip 119 matches the slide groove 118, and the clamping strip 119 is inserted into the slide groove 118;

[0042] The tractor 1 is provided with a lighting lamp and a camera, the lighting lamp provides illumination light, and the camera takes underwater salvage video;

[0043] Working principle:

[0044] The traction seat 121 is connected to the salvage ship. When the salvage ship moves on the water surface, the traction seat 121 is driven to move synchronously. The movement of the traction seat 121 drives the telescopic tube 112 to move synchronously through the connecting rod 122. The movement of the telescopic tube 112 drives the fixed rod 111 to move synchronously. The movement of the telescopic tube 112 also drives the rotating tube 51 to move synchronously through the sleeve tube 52. The movement of the rotating tube 51 drives the adjusting rod 54 to move synchronously. The movement of the telescopic tube 112 and the fixed rod 111 drives the anchor hook 3 to move in the water through the connecting rope 2. The anchor hook 3 is used to hook the object to be salvaged to achieve rescue and salvage.

[0045] During the salvage process, one end of the adjusting rod 54 is always in contact with the bottom of the water, so that the anchor hook 3 maintains a certain distance from the bottom of the water to prevent the anchor hook 3 from hooking foreign objects on the bottom of the water. When it is necessary to adjust the distance between the anchor hook 3 and the bottom of the water, the third locking screw 55 is loosened to move the adjusting rod 54 on the rotating tube 51 along the axis of the rotating tube 51. After the adjustment is completed, the third locking screw 55 is tightened to achieve the fixation between the adjusting rod 54 and the rotating tube 51. When it is necessary to adjust the angle of the adjusting rod 54, the second locking screw 53 is loosened to rotate the sleeve on the telescopic tube 112. The rotation of the sleeve drives the adjusting rod 54 to rotate synchronously through the rotating tube 51. After the angle adjustment is completed, the second locking screw 53 is tightened.

[0046] After two adjacent connecting ropes 2 are connected by the limiting strip 4, the positions of the two adjacent connecting ropes 2 in the water can be limited to avoid the distance between the two adjacent connecting ropes 2 being too small or too large, that is, to avoid the distance between the two adjacent anchor hooks 3 being too small or too large to affect the salvage effect;

[0047] In addition, the position between each anchor hook 3 and the tractor 1 is controlled by the pull rope 56 to prevent the anchor hook 3 from deviating as a whole, thereby further improving the salvage effect;

[0048] When adapting to waters of different widths, loosen the first locking screw 113 to move the telescopic tube 112 on the fixing rod 111 along the axis direction of the fixing rod 111, thereby adjusting the distance between the two telescopic tubes 112, that is, adjusting the salvage width. After the telescopic tubes 112 are adjusted, tighten the first locking screw 113. At the same time, the number of connecting ropes 2 between the two telescopic tubes 112 is adjusted according to the number of first hook holes 114 between the two telescopic tubes 112 after adjustment.

[0049] The movable buckle 117 is connected with the first hook hole 114 and the second hook hole 116 to facilitate the disassembly and assembly of the connecting rope 2. During the storage process, the movable buckle 117 is removed and the distance between the two telescopic tubes 112 is shortened to reduce the overall volume of the device, thereby facilitating storage.

[0050] In summary, the position of two adjacent anchor hooks 3 in the water is limited by the limit bar 4 to prevent the distance between the two adjacent anchor hooks 3 from being too small or too large to affect the salvage effect. The position between each anchor hook 3 and the tractor 1 is controlled by the pull rope 56 to prevent the anchor hook 3 from running off as a whole, thereby further improving the salvage effect. Moreover, during the storage process, the distance between the two telescopic tubes 112 is reduced to reduce the overall volume of the device, thereby achieving the effect of facilitating storage.

[0051] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
