Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power generation technology, in particular to a kind of wind turbine nacelle moisture-proof device. BACKGROUND

[0002] Wind power generation is a kind of renewable energy technology by converting wind kinetic energy into electrical energy. Wind energy is a kind of environment-friendly and pollution-free energy form, for example, windmill and other equipment can perform pumping and grinding work without generating additional pollution.

[0003] In a wind turbine, the nacelle is a closed space installed at the top of the tower, used to store critical components such as generators, gearboxes, transmissions and control systems. It not only ensures the safety of these internal components, but also provides a stable working environment for them, making maintenance easier, so as to ensure that the wind turbine can operate safely, stably and efficiently. Therefore, it is crucial to maintain the dryness inside the nacelle, which not only protects the nacelle itself, but also protects the entire wind power generation system.

[0004] However, the moisture-proof design of the related art wind turbine mainly focuses on improving the sealing of the nacelle or improving the ventilation conditions, but it is difficult to combine the two, for example, the heat dissipation holes of the rear nacelle box body are easy to cause the accumulation of moisture; in addition, the maintenance period of the nacelle is usually three to six months, but in the plum rain season or periods with more rainfall, the desiccant used may need to be replaced more frequently, which causes inconvenience in maintenance due to the particularity of the nacelle location; moreover, the nacelle contains a large number of electrical components. If too many moisture-proof and drying devices are added inside, it may affect the internal heat dissipation effect. Moreover, in an environment with thin air, the working efficiency of the dehumidifier may decrease, resulting in unsatisfactory dehumidification effect or the need for longer time to achieve the expected effect, and additional energy consumption.
