Description

Technical Field

[0001] This utility model relates to the field of marine anchor winches, specifically a corrosion-resistant marine anchor winch. Background Technology

[0002] Marine anchor winches are typically installed on the main deck at the bow and stern of a ship for use when raising, dropping, and mooring anchors. There are two types of anchor winches: horizontal and vertical. Horizontal anchor winches are generally used on merchant ships. With the rise of the yacht industry, in order to save costs and increase aesthetics, the demand for anchor winches is increasing, and the performance requirements for anchor winches are becoming more and more stringent.

[0003] Existing marine anchor winches are typically installed exposed to the elements. Seawater, salt spray, and humid air come into contact with the winch body, and these substances are significant contributors to corrosion, particularly to the anchor chains. Prolonged corrosion accelerates component damage, requiring more frequent maintenance and parts replacement. This not only increases the workload for maintenance personnel but also necessitates greater time and labor costs. Therefore, a corrosion-resistant marine anchor winch is proposed. Utility Model Content

[0008] The protective box contains a protective mechanism, which includes a first motor, a support rod, a rotating roller, a support rod, a baffle, a fixed roller, a fixed block, a heating resistance wire, a fan, a ventilation duct, a fixed block, a filter screen, a second motor, and an axial flow fan.

[0009] Preferably, the first motor is fixedly installed inside the protective box, and the support rod is fixedly sleeved on the outer surface of the output shaft of the first motor;

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a corrosion-resistant marine anchor winch, which has the following beneficial effects:

[0020] 1. This corrosion-resistant marine anchor winch uses a first motor and subsequent components to close the baffles, creating a sealed environment that prevents external seawater, salt spray, humid air, etc., from contacting the anchor winch body. These substances are important factors causing anchor winch corrosion. The sealed environment can isolate the anchor winch from the corrosive external environment and reduce the risk of corrosion.

[0021] 2. This corrosion-resistant marine anchor winch uses a heating resistance wire to generate heat, which is then dispersed by a fan to ensure even heating of the air inside the protective box. This accelerates the evaporation of seawater from the anchor chain. Simultaneously, the axial fan generates axial airflow, which accelerates the airflow inside the protective box and draws it out, improving drying efficiency. This allows the air inside the protective box to quickly reach a dry state, reducing the time that humid air can corrode the anchor winch body. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a new technical solution: a corrosion-resistant marine anchor winch, including a protective box 1, and an anchor winch body 2 is installed inside the protective box 1;

[0029] The protective box 1 is equipped with a protective mechanism, which includes a first motor 3, a support rod 4, a rotating roller 5, a support rod 6, a baffle 7, a fixed roller 8, a fixed block 9, a heating resistance wire 10, a fan 11, a ventilation duct 12, a fixed block 13, a filter screen 14, a second motor 15, and an axial flow fan 16.

[0030] Furthermore, the first motor 3 is fixedly installed inside the protective box 1, and the support rod 4 is fixedly sleeved on the outer surface of the output shaft of the first motor 3;

[0031] The rotating roller 5 is rotatably sleeved in the inner wall of the support rod 4.

[0032] Furthermore, two support rods 6 are rotatably sleeved on the outer surface of the rotating roller 5, and two baffles 7 are rotatably connected to the ends of the two support rods 6 away from the rotating roller 5.

[0033] Furthermore, the two fixed rollers 8 are respectively rotated and sleeved on the inner surfaces of the two baffles 7, and the two fixed rollers 8 are fixedly installed on the inner surface of the protective box 1.

[0034] Furthermore, the fixing block 9 is fixedly installed on the inner surface of the upright plate of the protective box 1, and the heating resistance wire 10 is fixedly installed on the left surface of the fixing block 9;

[0035] The fan 11 is fixedly installed on the inner surface of the vertical plate of the fixing block 9.

[0036] Furthermore, the ventilation duct 12 is fixedly installed on the upper surface of the protective box 1, and the fixing block 9 is fixedly installed at the output end of the ventilation duct 12;

[0037] The filter screen 14 is fixedly installed on the right surface of the fixing block 9.

[0038] Furthermore, the second motor 15 is fixedly installed in the inner wall of the fixed block 13, and the axial fan 16 is fixedly sleeved on the outer surface of the output shaft of the second motor 15.

[0039] This corrosion-resistant marine anchor winch, after anchoring is completed via the anchor winch body 2, activates the first motor 3. The first motor 3 drives the support rod 4, fixedly sleeved on the outer surface of the output shaft, to rotate in a circular motion. Simultaneously, the support rod 4 drives the rotating roller 5, which is rotated on the inner surface, to move forward. The rotating roller 5 drives the two support rods 6, which are rotated on the outer surface, to move backward. The two support rods 6 apply a backward pulling force to two baffles 7 at the end furthest from the rotating roller 5. At this time, the two baffles 7 rotate on the outer surface of the fixed roller 8, gradually becoming horizontal. The baffles 7 then... The system closes to form a sealed environment. At this time, the heating resistance wire 10 is powered by an external power source. The heat generated by the heating resistance wire 10 is dispersed by the fan 11, so that the air inside the protective box 1 is heated evenly. At this time, the seawater on the anchor chain evaporates. The second motor 15 is started, and the second motor 15 drives the axial flow fan 16 to rotate, generating axial airflow, accelerating the airflow inside the protective box 1, and sucking out the air inside the protective box 1 and discharging it through the ventilation duct 12. At this time, the air inside the protective box 1 is no longer corrosive, improving the corrosion resistance of the anchor machine body 2.

[0040] This corrosion-resistant marine anchor winch uses a first motor 3 and subsequent components to close the baffle 7, creating a sealed environment that prevents external seawater, salt spray, and humid air from contacting the anchor winch body. These substances are important factors causing anchor winch corrosion. The sealed environment isolates the anchor winch from the corrosive external environment, reducing the risk of corrosion. In this corrosion-resistant marine anchor winch, the heating resistance wire 10 generates heat, and the fan 11 disperses the heat, ensuring that the air inside the protective box 1 is heated evenly, accelerating the evaporation of seawater from the anchor chain. At the same time, the axial flow fan 16 rotates to generate axial airflow, accelerating the airflow inside the protective box 1 and drawing it out, improving drying efficiency and quickly drying the air inside the protective box 1, reducing the time for humid air to corrode the anchor winch body 2.

[0041] Structural Description:
