The two ends of the pressing plate 6 are slidably connected to the inner side of the first slide groove 8, and the first slide groove 8 provides a sliding space for the pressing plate 6. The inner wall of the hydraulic winch body 1 is located above the first slide groove 8 and is fixedly connected with an auxiliary plate 9. The bottom end of the auxiliary plate 9 is provided with an electric telescopic rod 7. The top end of the electric telescopic rod 7 is fixedly connected to the bottom end of the auxiliary plate 9, and the bottom end of the electric telescopic rod 7 is fixedly connected to the top of the pressing plate 6.

[0031] Reference Figure 4 and Figure 5The side wall of the hydraulic winch body 1 is located on the outside of the hydraulic motor 2 and is clamped with a waterproof shell 12. The waterproof shell 12 provides protection for the hydraulic motor 2. The waterproof shell 12 is provided with a sealing rubber block 13 near the side wall of the hydraulic winch body 1. The sealing rubber block 13 improves the sealing performance inside the waterproof shell 12. The sealing rubber block 13 is close to the side wall of the hydraulic winch body 1 and contacts the side wall of the hydraulic winch body 1.

[0032] Working principle: First, when using this type of marine hydraulic winch, the device is installed and connected to the hull first. Then, when the wire rope is wound on the outside of the rope drum 4, the electric telescopic rod 7 drives the pressing plate 6 to descend. At this time, the pressing plate 6 slides inside the first slide groove 8. The first slide groove 8 provides a sliding space for the pressing plate 6. Then the auxiliary block 10 and the tungsten steel rod 11 descend along with the descent of the pressing plate 6. The tungsten steel rod 11 contacts the wire rope. The bottom end of the tungsten steel rod 11 is designed with an inclined surface, so that the wire rope is subjected to a downward pressing force, so that the wire rope is wound on the rope drum 4 in an orderly manner, thereby improving the stability of the winding of the rope drum 4.

[0033] Secondly, when the ship is sailing on the sea and encounters extremely bad weather, the waterproof shell 12 provides protection for the hydraulic motor 2, and the sealing rubber block 13 provides sealing for the inside of the waterproof shell 12, so that the hydraulic motor 2 will not rust the internal components due to water vapor and the like, resulting in malfunction. Then, when the hydraulic motor 2 needs to be maintained after uninterrupted use and the waterproof shell 12 needs to be disassembled, it is only necessary to slide the slider 17 away from the limit block 18. The second slide groove 16 provides sliding space for the slider 17, and the limit block 18 is deformed, so that the slider 17 is separated from the limit of the limit block 18, and the connecting ring 14 is separated from the penetration of the slider 17, so that the waterproof shell 12 can be disassembled, and the hydraulic motor 2 can be maintained, and finally the dry work is completed.
