The drum, as one of the key components of the anchor winch, plays a vital role in the operation of the anchor winch.

[0003] In the prior art, the patent number is CN219058389U, and the name is a reel for an anchor winch, comprising a winding section, a first through hole being provided in the middle of the winding section, a reinforcing rib being provided on the first through hole, a rope head section being provided on the right side of the winding section, a second through hole being provided in the middle of the rope head section, the right end of the reinforcing rib passes through the second through hole, and grooves are provided in the middle of the upper and lower sides of the rope head section, a return spring is fixedly connected to the right side of the groove, a boss is fixedly connected to the left side of the return spring on the same side, a partition is fixedly connected to the opposite side of the boss, and threaded walls are provided on the left and right ends of the reinforcing rib, the reinforcing rib is placed in the first through hole and the second through hole, the winding section and the rope head section are fixed by screwing the nut, and when disassembly is required, the nut is loosened to take out the reinforcing rib, making the drum more convenient to install, transport and maintain, and greatly reducing expenses.

[0004] However, existing windlasses are typically designed with a mechanical tooth-type clutch, which transmits the driving force from the power source to the working drum via the main shaft and clutch. The tooth-type clutch and drum are loosely mounted on the main shaft. The inner hole of the tooth-type clutch is equipped with a hexagonal or sliding key. A shift fork allows axial sliding, engaging or disengaging the fixed clutch tooth on the drum to transmit force. This is typically an open-type arrangement.

7. The anti-icing device for the anchor winch clutch in a low-temperature environment according to claim 6, characterized in that: A plug-in rod (38) is fixed on the surface of the lifting ring (28) on the surface of the first clutch (9). The plug-in rod (38) is plugged into the interior of the first clutch (9), and the plug-in rod (38) can be telescopically moved inside the first clutch (9). A plurality of groups of supporting blocks (39) are fixed on the surface of the lifting ring (28). The supporting blocks (39) move up and down along with the lifting ring (28). After the supporting blocks (39) rise, they support the surface of the force-bearing block (32), so that the force-bearing block (32) moves after being supported by the supporting blocks (39).

8. The anti-icing device for the anchor winch clutch in a low-temperature environment according to claim 7, characterized in that: The plug-in rod (38) on the surface of the lifting ring (28) on the surface of the second clutch (10) is plugged into the surface of the second clutch (10), and the second clutch (10) can move on the surface of the second rotating rod (8).

9. The anti-icing device for the anchor winch clutch in a low-temperature environment according to claim 8, characterized in that: The second spring (35) moves under the support of the support block (39), so that the ball (34) is supported on the end of the rotating ring (23), and the limiting ring (29) is supported on one side of the limiting groove (30).

10. The anti-icing device for the anchor winch clutch in a low-temperature environment according to claim 9, characterized in that: After the second clutch (10) approaches the first clutch (9), the meshing teeth (16) can be inserted into the meshing groove (15). After the meshing teeth (16) are inserted into the meshing groove (15), the first clutch (9) and the second clutch (10) move synchronously. The other end of the push rod (19) is connected to the driving device. The driving device drives the push rod (19) to move horizontally, driving the vertical rod (21) and the second connecting plate (22) to move.
