[0018] like Figure 1-2 As shown, a rust-proof anchor winch includes an engine 1, a reducer 2, and an anchor chain wheel 3. The engine 1 and the reducer 2 are connected by a coupling, and the reducer 2 and the anchor chain wheel 3 are connected by a gearbox 4. The anchor chain wheel 3 is surrounded by a protective shell 5, which consists of a side plate 501, a top cover 502, and a bottom plate 503. An air intake channel 5011 extends from the right side plate 501, and a fan (not shown in the figure) is installed in the air intake channel 5011. A ventilation hole 5012 is provided at the top of the side plate 501. The top cover 502 is hinged to the side plate 501, and baffles 5021 extend downward around the top cover 502. A hole 5013 is provided on the rear side plate 501, and an anchor chain 6 is installed in the hole 5013 and connected to the anchor chain wheel 3.

[0019] like Figure 1 As shown, a water outlet pipe 7 is provided at the junction of the bottom of the side plate 501 and the bottom plate 503. A rain guard edge (not shown in the figure) extends from the upper edge of the hole 5013, which effectively prevents rainwater from entering the anchor chain wheel area. Both the water outlet pipe 7 and the rain guard edge are inclined downwards to facilitate the drainage of internal water and prevent corrosion.

[0020] like Figure 1-2 As shown, after the top cover 502 and the side plate 501 are flipped together, the lower edge of the baffle 5021 is lower than the plane where the ventilation hole is located, and there is a gap between the baffle 5021 and the side plate 501.

[0021] like Figure 1-2 As shown, a rainproof grille (not shown in the figure) is provided at the opening of the air intake channel 5011 to prevent rainwater from directly entering the air intake channel.

[0022] like Figure 1 As shown, the top cover 502 is equipped with a flip handle 5022, which makes it easy for operators to open or close the top cover for maintenance. At the same time, on sunny days, the top cover can be opened directly without covering, and the anchor chain wheel area can be dehumidified by the fan and solar heat, reducing moisture and further reducing the risk of corrosion.

[0023] The working principle of this utility model is as follows: When the engine starts, power is transmitted to the reducer through the coupling; the reducer transmits power to the gearbox through its internal gear transmission system; the gearbox further transmits power to the anchor chain wheel, causing it to start rotating. The anchor chain wheel is connected to the anchor chain, and when it rotates, it can drag the anchor chain to perform anchoring or anchoring operations. A protective shell is provided around the anchor chain wheel. This protective shell consists of side plates, a top cover, and a bottom plate, forming a closed space that effectively prevents the anchor chain wheel and anchor chain from being corroded by the external environment, especially preventing rust. When the fan is running, outside air can be introduced, and moisture inside the protective shell can be discharged through the ventilation holes to keep the interior dry. At the same time, a water outlet pipe is provided at the junction of the bottom of the side plate and the bottom plate to drain the water accumulated inside the protective shell in a timely manner, preventing moisture retention that could lead to rust.

[0024] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
