[0017] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0018] The present embodiment provides a compact mooring cable pay-out winch for mooring equipment, by improving the structure of the traditional pay-out winch, such as integrating the drive motor, electromagnetic clutch and other components into the previously idle internal space of the mooring cable winding drum, and at the same time omitting or simplifying the related belt transmission mechanism, shaft support, panel, cover and winch integrated base, thereby greatly reducing the external size and overall weight of the pay-out winch, making its structure more compact.

[0019] The structure of the mooring cable retracting winch is as follows: Figure 2 and Figure 3 As shown, it includes: a mooring cable winding drum 1, a cable arrangement assembly 3, a cross-spoke drum transmission support 8, a motor 4, an electromagnetic clutch 5 and a winch bracket 10.

[0020] The connection relationship is as follows: the mooring cable winding drum 1 is a hollow cylindrical structure with openings at both ends, and the mooring cable is wound on the mooring cable winding drum 1; a cross-spoke drum transmission support 8 is arranged in the mooring cable winding drum 1, and the cross-spoke drum transmission support 8 includes: a central sleeve arranged along the axial direction of the mooring cable winding drum 1 and transmission support rods arranged on the outer circumference of the sleeve and distributed in a cross shape along the radial direction of the mooring cable winding drum 1; the four ends of the transmission support rods are respectively fixedly connected to the inner wall of the mooring cable winding drum 1; the central sleeve of the cross-spoke drum transmission support 8 is fixedly connected to the rotating shaft 13.

[0021] The winch bracket 10 is the supporting structure of the entire mooring cable pay-out winch, which is similar to the winch-connected base of a traditional mooring cable pay-out winch. In order to reduce the overall weight of the pay-out winch, the winch bracket 10 is designed as a frame structure, including support plates arranged at both axial ends of the mooring cable winding drum 1 and three beams parallel to the axial direction of the mooring cable winding drum 1 for connecting the two support plates. The mooring cable pay-out winch is supported on the ground or the installation platform by two beams located below.

[0022] The two ends of the cable arrangement assembly 3 are respectively supported on the support plates at the two ends of the winch bracket 10, and the mooring cable passes through the cable arrangement hole on the cable arrangement assembly and is connected to the moored drone; the cable arrangement assembly 3 is used to arrange the mooring cable on the mooring cable winding drum 1 in an orderly manner. The structure of the cable arrangement assembly 3 is the same as that of the traditional mooring cable retracting winch (such as Figure 1 The cable arrangement assembly 3 shown in the figure comprises: a cable arrangement transmission unit, a cable arrangement screw and a cable arrangement polished rod. The axis of the cable arrangement screw is parallel to the axis of the mooring cable winding drum 1. The cable arrangement transmission unit is used to drive the cable arrangement screw to rotate. The cable arrangement transmission unit is a transmission mechanism that is driven by a toothed belt (or gear) with the rotating shaft 13, such as Figure 1 The transmission mechanism 2 shown is a fixed ratio linkage. The wire arranging seat cooperates with the wire arranging screw through the threaded hole thereon to form a screw nut pair, which converts the rotation of the wire arranging screw into the linear motion of the wire arranging seat along the axis of the wire arranging screw. The mooring cable passes through the cable hole on the wire arranging seat and is wound around the mooring cable winding drum 1. In order to prevent the screw wire arranging seat from being stuck due to a large lateral tension, a wire arranging light rod parallel to the axis of the wire arranging screw is set as a guide rail, and a linear guide rail is used to assist in wire arranging. Specifically: the wire arranging seat is processed with a light hole parallel to the axis of its threaded hole, which is used to be mounted on the wire arranging light rod, and the wire arranging light rod plays a guiding role for the linear motion of the wire arranging seat.

[0023] In this solution, the motor fixing seat is a cylindrical structure, that is, Figure 2 and Figure 3The motor fixing cylinder 9 is shown; the motor fixing cylinder 9 is coaxially arranged inside the mooring cable winding drum 1, and one end of the motor fixing cylinder 9 is fixed on the support plate on one side of the winch bracket 10; a motor fixing partition 11 is arranged inside the motor fixing cylinder 9, and the motor 4 is fixed on the motor fixing partition 11; the active end of the electromagnetic clutch 5 is connected to the power output shaft of the motor 4, and the driven end is arranged in the center sleeve of the cross-spoke drum transmission support 8 and fixedly connected to the center sleeve, and the center sleeve is fixedly connected to the rotating shaft 13, and the rotating shaft 13 is sleeved with the photoelectric slip ring 14 and supported on the support plate on the other side of the winch bracket 10 through a bearing; when the electromagnetic clutch 5 is engaged, the power of the motor 4 can be transmitted to the cross-spoke drum transmission support 8 and the rotating shaft 13 respectively.

[0024] At this point, the drive motor and the electromagnetic clutch are built-in. When the electromagnetic clutch 5 is in the engaged state, the motor 4 rotates, and the mooring cable winding drum 1 can be driven to rotate through the cross-spoke drum transmission support 8 to realize the mooring cable retraction and release process.

[0025] Compared with the product before improvement ( Figure 1 The volume and weight were reduced by 40% and 50% respectively.

[0026] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
