Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically a heat dissipation device for offshore wind turbine towers. Background Technology

[0002] Offshore wind power is playing an increasingly important role in the field of renewable energy, and tower heat dissipation is one of the key factors to ensure the good operation of wind turbines.

[0003] Currently, existing offshore wind turbine tower cooling systems face numerous challenges in practical applications. Due to the unique environmental conditions at sea, the air is characterized by high humidity and high salinity. When conventional cooling devices use methods such as blowing air to dissipate heat from the tower, the high humidity and salinity of the sea breeze directly participates in the cooling process, adversely affecting the cooling effect. When the high-humidity sea breeze comes into contact with the cooling device and flows over related cooling components, moisture easily condenses on the equipment surface. This can not only hinder normal heat dissipation but also cause problems such as rust and corrosion, thereby reducing cooling efficiency and the overall service life of the equipment. Furthermore, the high salinity in the sea breeze, after coming into contact with the cooling device, gradually deposits on the equipment surface, forming a corrosive salt layer, further affecting the performance of the cooling device and accelerating the aging and damage of the equipment. However, most existing offshore wind turbine tower cooling systems on the market are not equipped with devices for pre-dehumidification and filtration of sea breeze, making it difficult for the cooling devices to effectively cope with the adverse effects of the special marine environment and ensuring the high efficiency and stability of tower cooling. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a wind turbine tower heat dissipation device that can effectively dehumidify and desalinate sea air, preventing water vapor and salt from adversely affecting the equipment during heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind turbine tower heat dissipation device includes a filter pipe, a multi-stage filtration device, a cooling fan, a bracket, and a water storage pipe; the filter pipe is equipped with a multi-stage filtration device and is fixedly mounted on the bracket; a cooling fan is installed on the air outlet pipe at the top of the filter pipe; the water storage pipe is connected to the bottom of the filter pipe through multiple drain pipes, and an electric heating wire is wound around the outside of the water storage pipe.

[0007] The multi-stage filtration device includes a metal filter, filter cotton, and a cyclone filter; the metal filter, filter cotton, and cyclone filter are arranged sequentially inside the filter tube and are arranged in a direction that gradually moves away from the air inlet of the filter tube; the air outlet pipe and the cyclone filter are positioned correspondingly.

[0008] Preferably, a thin water pipe is connected to the bottom of the water storage pipe, and an electric water valve is installed at the outlet of the thin water pipe;

[0009] Preferably, the air inlet end of the filter tube is provided with a rain cap;

[0010] Preferably, the air inlet of the filter tube is provided with an air inlet concave baffle, the middle of the air inlet concave baffle is a filter cone mesh, and the end of the filter cone mesh facing the multi-stage filtration device is the small end;

[0011] Preferably, the end of the filter tube is a detachable cap;

[0012] Preferably, a first thermometer is installed on the water storage pipe, and a second thermometer and a hygrometer are installed on the filter pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device can perform multi-stage filtration of sea breeze. Through the multi-stage filtration structure, it can effectively intercept various impurity particles carried in the sea breeze, such as sand and dust, marine microbial debris, etc., thereby greatly reducing the content of impurities in the heat dissipation air, creating a cleaner air environment for the subsequent heat dissipation process, avoiding physical damage to the heat dissipation device and related tower equipment caused by the accumulation of impurities, and extending the service life of the equipment.

[0014] 2. This device can dehumidify sea breezes with high humidity, removing most of the moisture. After dehumidification, the air blown out for heat dissipation is drier, reducing the risk of equipment rust and corrosion caused by long-term moisture retention.

[0015] 3. This device can significantly reduce the salt content in the cooling air. In the filtration stage, it can block some large particles of impurities carrying salt, thereby avoiding adverse effects such as corrosion and scaling caused by high-salt sea air on the equipment, and reducing the maintenance cost of the equipment.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a wind turbine tower heat dissipation device includes a filter pipe 1, a multi-stage filtration device, a cooling fan 12, a bracket 8, and a water storage pipe 7. The filter pipe 1 is equipped with a multi-stage filtration device and is fixedly installed on the bracket 8. The multi-stage filtration device performs three-stage filtration of sea air, filtering out particulate matter, impurities, droplets, etc. in the sea air, thereby filtering out some of the salt and moisture in the sea air and reducing its impact on the equipment.

[0025] A cooling fan 12 is installed on the air outlet 13 at the top of the filter tube 1; the cooling fan 12 corresponds to the air after multi-stage filtration.

[0026] The water storage pipe 7 is connected to the bottom of the filter pipe 1 through multiple drain pipes 5, and an electric heating wire 6 is wrapped around the outside of the water storage pipe 7. The drain pipes 5 are used to drain the water inside the filter pipe 1, and the electric heating wire 6 is used to heat the water storage pipe 7 according to the temperature.

[0027] The multi-stage filtration device includes a metal filter 18, a filter cotton 17, and a cyclone filter 16. The metal filter 18, filter cotton 17, and cyclone filter 16 are sequentially arranged inside the filter tube 1, gradually moving away from the air inlet of the filter tube 1. The outlet duct 13 and the cyclone filter 16 are positioned correspondingly. In this embodiment, the metal filter 18 and cyclone filter 16 are existing products. All three components—metal filter 18, filter cotton 17, and cyclone filter 16—can filter out particulate matter in the air, and the cyclone filter 16 can also filter out liquid droplets in the air.

[0028] In this embodiment, a thin water pipe is connected to the bottom of the water storage pipe 7, and an electric water valve 3 is installed at the outlet of the thin water pipe. Opening the electric water valve 3 will drain the water in the water storage pipe 7.

[0029] In this embodiment, a rain cap 2 is provided at the air inlet end of the filter pipe 1; it is used to shield and protect the air inlet of the filter pipe 1.

[0030] In this embodiment, an air inlet concave baffle 14 is provided at the air inlet of the filter pipe 1. The middle of the air inlet concave baffle 14 is a filter cone mesh 15, and the end of the filter cone mesh 15 facing the multi-stage filtration device is the smaller end. The air inlet concave baffle 14 is used to block small animals such as birds from entering the filter pipe 1. The gradually decreasing opening of the filter cone mesh 15 further prevents small animals from crawling into the filter pipe 1.

[0031] In this embodiment, the end of the filter tube 1 is a disassembly cover 9; the disassembly cover 9 can be opened to facilitate maintenance of the inside of the filter tube 1.

[0032] In this embodiment, a first thermometer 4 is installed on the water storage pipe 7, and a second thermometer 11 and a hygrometer 10 are installed on the filter pipe 1. The first thermometer 4 is used to detect the temperature of the water storage pipe 7. In a low-temperature environment, the electric heating wire 6 is controlled to work to heat the ice inside the water storage pipe 7 so that it can be thawed into water and discharged. The design of the second thermometer 11 and the hygrometer 10 can detect the temperature and humidity of the air inside the cyclone filter 16. When the temperature and humidity reach the requirements, the cooling fan 12 is controlled to work to dissipate heat from the wind turbine tower.

[0033] Working principle

[0034] When in use, this device is installed in the nacelle of a wind turbine. Sea air enters the filter tube 1 after being filtered by the filter cone mesh 15, and then undergoes primary filtration through the metal filter 18. The metal filter 18 filters out particulate matter and impurities in the air. The air after being filtered by the metal filter 18 flows through the filter cotton 17 for secondary filtration. The filter cotton 17 further filters out solid particles and suspended matter in the air. Then the air enters the cyclone filter 16, which performs tertiary filtration of the air, filtering out dust particles and droplets in the air. Some moisture is also filtered out during the primary and secondary filtration stages.

[0035] As air flows through the filter tube 1, the filtered water enters the water storage tube 7 through the drain tube 5 under the action of gravity, and then is discharged through the thin water tube connected to the bottom. The thin water tube is equipped with an electric water valve 3, which can control the opening and closing of the drain.

[0036] The electric heating wire 6 on the water storage pipe 7 operates at low temperatures to heat the ice inside the water storage pipe 7, preventing the water from freezing and being unable to drain due to low temperatures.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
