[0002] Offshore wind turbine installation vessels are specialized ships used for the construction of offshore wind farms, primarily for the installation, commissioning, and maintenance of wind turbine generators. Equipped with large lifting equipment, sophisticated positioning systems, and a stable working platform, these vessels can operate precisely in the harsh marine environment. The hull design incorporates wind and wave resistance, ensuring safety and efficiency during offshore wind farm construction. Offshore wind turbine installation vessels play a crucial role in the wind power industry and are key equipment for the successful completion of offshore wind power projects.

[0003] Offshore wind turbine installation vessels are specialized engineering vessels used for the installation of offshore wind turbines, primarily for the installation of towers, blades, and mainframes. These vessels adjust their height by raising and lowering their four legs, depending on the construction depth, and utilize their onboard heavy-duty cranes for lifting operations.

[0004] Since offshore wind turbine installation vessels are located in deep sea areas more than 100 kilometers offshore for extended periods, the high salt spray and high humidity environment can easily cause the components in the power distribution cabinets of offshore wind turbine installation vessels to become damp and corroded by salt, leading to damage to the power distribution system. Therefore, a dehumidifying and salt spray-proof power distribution cabinet for offshore wind turbine installation vessels is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a dehumidifying and salt spray-proof power distribution cabinet for offshore wind power installation vessels. It aims to improve the problem in the prior art that the high salt spray and high humidity environment easily causes the components in the power distribution cabinet of the offshore wind power installation vessel to become damp and corroded by salt, resulting in damage to the power distribution system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A marine dehumidification and salt spray prevention power distribution cabinet for offshore wind power installation includes a cabinet body.

[0030] 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.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a marine dehumidification and salt spray prevention power distribution cabinet for offshore wind power installation, including a cabinet body 1. The cabinet body 1 has a sealed structure combined with a corrosion-resistant coating, which can effectively block the intrusion of external salt spray. Two cabinet doors 3 are installed on one side of the cabinet body 1 via hinges. When the cabinet doors 3 are closed by the hinges, they form a sealed space with the cabinet body 1 to prevent humid air from seeping in. A heating component is installed inside the cabinet body 1 and outside the cabinet body 1. The heating component achieves air circulation heating inside the cabinet through gradient distribution, avoiding local condensation.

[0032] An air supply fan 15 is installed on the inner wall of the distribution cabinet 1. The air supply fan 15 forces the heated dry air downward to form an upward airflow circulation. A semiconductor heating element 13 is installed on one side of the air supply fan 15. The semiconductor heating element 13 uses the Peltier effect to generate a stable heat source, avoiding the energy consumption fluctuations of traditional resistance heating. A heat sink 14 is installed on the outside of the air supply fan 15. The heat sink 14 accelerates heat exchange by increasing the contact area and improves the heating efficiency of the air inside the cabinet. An exhaust fan 20 is installed on the inner wall of the distribution cabinet 1. The exhaust fan 20 draws the humid air into the condenser dryer to achieve active separation of salt spray and water vapor.

[0033] A radiator 19 is installed on the outside of the suction fan 20. The radiator 19 quickly lowers the air temperature to the dew point through semiconductor cooling, causing moisture to condense. A condensate drain pipe 21 is installed on one side of the suction fan 20. The condensate drain pipe 21 is connected to the ship's drainage system to ensure that salt condensate is discharged from the cabinet in a timely manner. A semiconductor cooling chip 18 is installed on one side of the suction fan 20. The cold end of the semiconductor cooling chip 18 acts on the radiator 19, and the hot end is discharged through the second heat sink 17. A second heat sink 17 is installed on one side of the distribution cabinet 1. The external design of the second heat sink 17 avoids the waste heat from affecting the temperature control inside the cabinet and ensures cooling efficiency. A cooling fan 16 is installed on one side of the second heat sink 17. The cooling fan 16 accelerates the external airflow and quickly removes the waste heat generated by the semiconductor cooling chip 18.

[0034] refer to Figure 2 , Figure 3 ,and Figure 6 The heating components include a heating dryer 7, which heats air through bottom air supply, creating an upward airflow that carries moisture upwards. A second heating dryer 8 is installed outside the distribution cabinet 1, symmetrically distributed with the first heating dryer 7 to ensure temperature uniformity within the cabinet. A third heating dryer 11 is installed outside the distribution cabinet 1, located on the side wall of the cabinet, supplementing the heating of the edge areas and preventing the formation of cold zones. A fourth heating dryer 12 is installed outside the distribution cabinet 1, positioned at the top of the cabinet to prevent hot and humid air from accumulating at the top. To prevent moisture buildup, a condenser dryer 5 is installed on the outside of the distribution cabinet 1. The condenser dryer 5 uses top suction to centrally process the rising airflow with the highest moisture content. A condenser dryer 6 is also installed on the outside of the distribution cabinet 1. The condenser dryer 6 works in conjunction with the condenser dryer 5 to improve dehumidification efficiency. A condenser dryer 9 is also installed on the outside of the distribution cabinet 1. The condenser dryer 9 performs secondary dehumidification on the air in the middle of the cabinet to reduce residual humidity. A condenser dryer 10 is also installed on the outside of the distribution cabinet 1. The condenser dryer 10 enhances the air treatment at the bottom and prevents moisture from re-entering the circulation.

[0035] refer to Figure 1The switch 4 is installed on the outside of the cabinet door 3. The switch 4 adopts a salt spray-proof sealing design to prevent the contacts from getting damp and oxidizing. The instrument system 2 is installed on the outside of the cabinet body 1. The instrument system 2 monitors the temperature and humidity inside the cabinet in real time and controls the start and stop of the heating and cooling modules in linkage. The power distribution instruments and equipment are installed on the inner wall of the cabinet body 1. The power distribution equipment maintains stable operation through the dry air circulating inside the cabinet to avoid salt spray corrosion.

[0036] Working principle: The distribution cabinet 1 is isolated from external salt spray by a sealed structure and corrosion-resistant coating. The heating dryer 7 is located at the bottom of the cabinet. Its semiconductor heating element 13 heats the air through the radiator 14. The fan 15 blows the hot air downwards, forming an upward airflow that forces the moisture to rise to the top. The symmetrically distributed heating dryers 8 ensure uniform temperature inside the cabinet. The heating dryers 11 on the side walls supplement the heating of the edge areas, and the heating dryer 12 on the top prevents the retention of hot and humid air.

[0037] The condenser dryer 5 at the top of the cabinet draws in humid air through the suction fan 20. The cooler 19 cools the air to the dew point by acting on the cold end of the thermoelectric cooler 18. Salt spray and water vapor condense and separate. The condensate is discharged through the condensate drain pipe 21. The condenser dryer 6 works with the condenser dryer 5 to process the high humidity airflow at the top. The condenser dryer 9 in the middle dehumidifies the air twice to reduce residual humidity. The condenser dryer 10 at the bottom intercepts moisture and recirculates it. The waste heat from the hot end of the thermoelectric cooler 18 is discharged through the external heat sink 17 and the cooling fan 16.

[0038] Instrumentation system 2 monitors temperature and humidity in real time and controls the heating and cooling modules in conjunction with them. The salt spray-proof sealing design of the switch 4 in the distribution cabinet protects the contacts. Dry air is continuously circulated inside the cabinet to ensure that the equipment is protected from salt spray corrosion and to meet the operating requirements of the marine environment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
