DETAILED DESCRIPTION

[0035] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0036] Example 1, please refer to Figure 1-4 :

[0037] A manual cable storage device includes a support mechanism and a winch.

[0038] The support mechanism comprises: a first support plate 110 and a second support plate 120 which are arranged in parallel and symmetrically, a bearing seat 170 is arranged on the first support plate 110 and the second support plate 120 respectively, and a plurality of parallel and equal-length first reinforcement columns 310 are installed between the first support plate 110 and the second support plate 120;

[0039] The winch includes a first disc 210, a second disc 220 and a rotating handle 230; a first bearing 250 is connected to the center of the disc body of the first disc 210, a second bearing 260 is connected to the center of the disc body of the second disc 220, the first disc 210 is rotatably connected to the bearing seat 170 on the first support plate 110 through the first bearing 250, and the second disc 220 is rotatably connected to the bearing seat 170 on the second support plate 120 through the second bearing 260; a plurality of parallel spokes 240 of equal length are installed between the disc bodies of the first disc 210 and the second disc 220; one end of the rotating handle 230 is coaxially connected to the first bearing 250 as a whole, and a slip ring interface 270 is provided on the second bearing 260, and the slip ring interface 270 is used to install various optoelectronic slip rings.

[0040] By adopting the above scheme: during the process of cable winding, the staff rotates the rotating handle 230, and the first disc 210 and the second disc 220 rotate synchronously with the rotation of the rotating handle 230. The cable is wound on the spokes 240 as the first disc 210 and the second disc 220 rotate. In this way, the winding and storage of the cable is realized by manpower. Due to the limited physical strength of human beings, this scheme is suitable for working scenarios where cables with small diameters and short lengths are wound and released. In the above scheme, the first reinforcing column 310 is configured to enhance the structural stability of the first support plate 110 and the second support plate 120.

[0041] In this example, the support mechanism further includes:

[0042] The first outer guard plate 130 and the second outer guard plate 140 are arranged in parallel and symmetrically, and the first outer guard plate 130 and the first support plate 110 are parallel to each other; the first support plate 110 and the second support plate 120 are both located between the first outer guard plate 130 and the second outer guard plate 140; a plurality of parallel and equal-length second reinforcement columns 320 are installed between the first outer guard plate 130 and the first support plate 110; a plurality of parallel and equal-length third reinforcement columns 330 are installed between the second outer guard plate 140 and the second support plate 120; openings are respectively provided on the plate body of the first outer guard plate 130 and the plate body of the second outer guard plate 140. The rotating handle 230 is configured as a foldable handle. That is, the rotating handle 230 can be freely switched between an unbent state and a bent state. When the rotating handle 230 is in a bent state, it is convenient for the staff to hold and rotate.

[0043] By adopting this solution: the handle interface on the first bearing 250 for coaxially connecting the rotating handle 230 is protected by utilizing the distance between the first outer guard plate 130 and the first support plate 110. To perform the operation of rotating the rotating handle 230, the rotating handle 230 extends out of the first outer guard plate 130 through the opening on the first outer guard plate 130. The slip ring interface 270 on the second bearing 260 for connecting the slip ring is protected by utilizing the distance between the second outer guard plate 140 and the second support plate 120. The structural stability between the first outer guard plate 130 and the first support plate 110 is strengthened by the second reinforcement column 320, and the structural stability between the second outer guard plate 140 and the second support plate 120 is strengthened by the third reinforcement column 330.

[0044] In this example, the support mechanism further includes: a first bottom plate 150 and a second bottom plate 160. The upper surface of the first bottom plate 150 is fixedly connected to the bottom of the first outer guard plate 130 and the bottom of the first support plate 110 as a whole; the upper surface of the second bottom plate 160 is fixedly connected to the bottom of the second outer guard plate 140 and the bottom of the second support plate 120 as a whole; the lower surface of the first bottom plate 150 and the lower surface of the second bottom plate 160 are respectively provided with universal wheels 500.

[0045] By adopting this technical solution: the stability between the first outer guard plate 130 and the first support plate 110 is further enhanced by the first bottom plate 150, the stability between the second outer guard plate 140 and the second support plate 120 is further enhanced by the second bottom plate 160, and the overall quick movement of the equipment is achieved through the universal wheel 500.

[0046] In this example, a positioning threaded hole is provided on the first disc 210, and a positioning screw 600 corresponding to the positioning threaded hole is installed on the first support plate 110, and the positioning screw 600 is further configured to allow its tip to enter / exit the positioning threaded hole by rotating forward / reverse. By adopting this technical solution: the function of capstan locking is achieved. Specifically: after the cable is wound up, the rotating handle 230 is first slowly rotated until the first disc 210 moves to a position where the positioning threaded hole is directly opposite to the positioning screw 600. Then, the positioning screw 600 is screwed into the first support plate 110, so that the tip of the positioning screw 600 moves toward the positioning threaded hole until the tip of the positioning screw 600 extends into the positioning threaded hole. At this time, the position locking of the first disc 210 and the first support plate 110 is achieved. When the capstan needs to be unlocked, the positioning screw 600 is rotated in the reverse direction so that its tip exits the positioning threaded hole, and the relative rotation of the first disc 210 and the first support plate 110 can be achieved.

[0047] Furthermore, in this example: the two ends of the first reinforcing column 310 are connected to the first support plate 110 and the second support plate 120 respectively by screws; the two ends of the second reinforcing column 320 are connected to the first outer guard plate 130 and the first support plate 110 respectively by screws; the two ends of the second reinforcing column 320 are connected to the second outer guard plate 140 and the second support plate 120 respectively by screws. By adopting this technical solution: the first reinforcing column 310, the second reinforcing column 320, and the third reinforcing column 330 are assembled by screws respectively, which reduces the weight of the equipment while ensuring sufficient strength and stability compared to the traditional welding connection.

[0048] In this example: the plate body of the first support plate 110, the plate body of the second support plate 120, the plate body of the first outer guard plate 130 and the plate body of the second outer guard plate 140 respectively include an aluminum alloy skeleton layer 410 and a high-density polyethylene layer 420 covering the surface of one side of the aluminum alloy skeleton layer 410. The aluminum alloy skeleton layer 410 is specifically made of aluminum alloy 7075. The first reinforcing column 310, the second reinforcing column 320 and the third reinforcing column 330 are respectively made of aluminum alloy round rods. By adopting this technical solution: the high-density polyethylene layer 420 is provided to further significantly reduce the deadweight of the equipment. The aluminum alloy skeleton layer 410 ensures that each support plate and outer guard plate has a certain rigidity. In addition, the surface of aluminum alloy 7075 has an oxidized black layer, which can effectively play an anti-corrosion role in a humid environment such as a ship deck, and is consistent with the color of the high-density polyethylene plate, so coloring can be avoided.

[0049] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
