[0030] The reciprocating slide 3 is used to guide the reversing and reciprocating movement of the cable array within the width of the drum during the retraction and release of the underwater winch. The reciprocating slide 3 is installed on the bracket 2. The reciprocating slide 3 is threadedly connected to the screw 23 and is slidably connected to the support rod 22, so as to realize the sliding of the reciprocating slide 3 on the bracket 2. The reciprocating slide 3 includes a seat frame 31 and a steering wheel 32. The seat frame 31 is hinged to the steering wheel 32. The steering wheel 32 can rotate around the seat frame 31 and the rotating fulcrum is coaxial with the cable outlet of the bracket 2. The fulcrum position must meet the requirement that the distance between the fulcrum and the tangent of the drum is greater than the bending radius R of the line array; the steering wheel is a 1 / 4 arc structure to realize 90° reversal of the cable array; the reciprocating slide 3 is used to guide the retraction and release path of the cable array within the allowed limited space;

[0031] The driving assembly is used to drive the screw 23 and the reel 1 to rotate.

[0032] In this embodiment, the driving assembly includes a transmission device 6 and a deep-sea motor 7. The transmission device 6 can adopt a common transmission structure such as gears and chains.

[0033] The reel 1 is used to store the cable array 5 and has a structure with a larger axial dimension and a smaller radial dimension. The reel 1 includes two flanges 11, a hollow cylinder 12, and a central axis 13. The flange 11 can be fixed to the cylinder by screws 14.

[0034] The bracket 2 is used to support the reel 1, the reciprocating slide 3, the transmission device 6, etc. Specifically, the bracket 2 has a cylindrical frame shape, including two side panels 21, two support rods 22, and a screw 23. The two side panels 21 are disc-shaped hollow structures, conforming to the shape of the vehicle.
