Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, the present invention provides a cooling and ventilation system for floating wind turbines, including:

[0037] The air cooler 4 is located on the outer wall of the floating foundation 1 of the floating wind power generating set, and is located above the water surface 20°;

[0038] The air inlet pipe 5 is arranged on the outer wall of the floating foundation 1 and is located above the water surface 20, and is used to introduce the outside air into the inside of the floating foundation 1;

[0039] The air guide pipe 6 is located inside the floating foundation 1, the upper port of the air guide pipe 6 communicates with the air cooler 4, and the lower port is located below the water surface 20;

[0040] The pipeline 2 is connected in series with the component to be cooled 8, the water pump 7 and the air cooler 4 in sequence to form a loop for the circulation of the cooling liquid; and

[0041] The controller 9 is electrically con...

Embodiment 2

[0051] When maintaining the equipment inside the floating foundation 1, the staff will enter the inside of the floating foundation 1 to perform operations. Because the embodiment 1 is provided with an air duct 6 inside the floating foundation 1, and the air duct air duct The area of ​​the air duct is more than 1 square meter, so the staff may stumble and fall into the air duct during operation, which poses a safety hazard. At the same time, the end of the air inlet pipe 5 connected to the air inlet is bent downward, although it can prevent the falling objects from entering the inside of the floating foundation and cause damage, but it cannot prevent such accidents as birds flying into this type of accident, and there is also a safety hazard. Hidden danger.

[0052] In order to solve the above-mentioned technical problems, further optimize on the basis of embodiment 1, adopt the following technical scheme, the cooling and ventilation system also includes a first protective net ...

Embodiment 3

[0055] In Example 1, such as figure 1 As shown, the air cooler 4 is installed on the top platform of the floating foundation 1. When it rains, the rainwater will directly pour into the air cooler 4, which will affect the service life of the air cooler 4, such as Short circuit fault.

[0056] In order to solve the above technical problems, further optimization on the basis of Example 1, the following technical scheme is adopted, a rain cover is set above the air cooler, the shape, size and material of the rain cover are not limited, and the rain cover can completely cover Air coolers so that rainwater cannot drip onto the air coolers. The installation method of the rain shield is not limited. In this embodiment, for example, riveting and screw connection can be used to provide better connection strength and resist the vibration caused by the turbulence of the sea surface.

[0057] Using the rain cover can prevent the rainwater from dripping on the air cooler and cause corrosi...

Abstract

The invention provides a cooling and ventilation system for a floating wind power generating set. The cooling and ventilation system comprises an air cooler, an air inlet pipe, an air duct, a pipelineand a controller, wherein the air cooler is arranged on the outer wall of a floating foundation of the floating wind generating set above a water surface; the air inlet pipe arranged on the outer wall of the floating foundation above the water surface, and is used for introducing outside air into the floating foundation; the air duct is arranged inside the floating foundation; an upper port of the air duct is connected to the air cooler, and a lower port is below the water surface; the pipeline is connected in series with parts to be cooled, a water pump and the air cooler in turn to form a loop for the circulation of cooling liquid; and the controller is electrically connected to the air cooler and the water pump, and is used for controlling the on-off of the air cooler and the water pump. The cooling and ventilation system can solve the technical problems that the traditional cooling system and ventilation equipment of the floating wind generating set are two independent devices, the manufacturing cost is high, and the cooling effect of the cooling system is not good enough under high-temperature environment conditions.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a cooling and ventilation system for floating wind power generators. Background technique [0002] In the construction of offshore wind farms, when the water depth is greater than 60 meters, compared with fixed foundation wind turbines, the technical and economic indicators of floating foundation wind turbines will be greatly improved, which is not limited by water depth and can simplify wind turbines Therefore, floating wind turbines have become an inevitable trend in the construction of offshore wind farms with water depths above 60 meters. [0003] At present, the cooling system of floating wind turbines basically directly borrows the cooling system of the fixed foundation, and uses the air-water cooling system to dissipate heat and cool down the transformer and converter. The system takes out the heat generated by the transformer and converter through the cooli...
