Wind driven generator cabin cover

Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a wind driven generator cabin cover. The wind driven generator cabin cover comprises a cabin cover body and a ventilation cavity, the ventilation cavity is arranged on the cabin cover body in a penetrating mode and located on the inner wall of the cabin cover body, a first heat transfer device and a second heat transfer device are connected to the upper face of the ventilation cavity, and the first heat transfer device is connected to equipment in a cabin. The second heat transfer device is arranged in the cabin. A reservoir is arranged at the top of the cabin cover body, and a water outlet is formed in the bottom of the cabin cover body and connected with a spray header arranged in the ventilation cavity through a water pipe. A fan is arranged in the cabin cover body. According to the wind driven generator cabin cover, heat generated by the equipment in the cabin is transferred into the ventilation cavity, then wind and water in the nature are fully utilized to take away the heat, and the wind driven generator cabin cover has the advantages of being energy-saving, environment-friendly, good in heat dissipation effect and convenient to maintain; the ventilation cavity made of metal materials improves the structural strength; the fan enables the temperature in the cabin cover to be uniform; and the equipment in the cabin is not in direct contact with the outside, so that faults caused by moisture, dust or other foreign matters are avoided.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a wind power generator nacelle cover. Background technique [0002] Wind energy is a renewable and clean energy that is currently available for large-scale development. Vigorously promoting wind power generation is conducive to the harmonious development of man and nature. Wind power generators use wind power to drive the blades to rotate, convert wind energy into mechanical energy, and then drive it through the blade shaft. A generator rotates a device that converts mechanical energy into electrical energy. According to the current wind turbine technology, power generation can start at a wind speed of about three meters per second (the degree of light wind). With the development of science and technology, the single-unit capacity and quantity of wind turbines are increasing. [0003] The nacelle cover is an important part of the wind turbine, which cont...

AI Technical Summary

Problems solved by technology

[0003] The nacelle cover is an important part of the wind turbine, which contains and protects the core components of the wind turbine, such as the generator, the gearbox and the electronic control system. Heat, in order to prevent them from overheating and malfunctioning, so the nacelle cover needs to be provided with a ventilation and heat dissipation structure; the ventilation and heat dissipation of the existing nacelle cover products is usually realized by directly opening ventilation holes or installing heat dissipation windows on the main body of the nacelle cover. Although the method is simple to manufacture and low in cost, if it is installed in a large area, it will destroy the structural integrity of the main body of the nacelle cover and affect its strength. If it is installed in a small area, the ventilation and heat dissipation effect will be poor. Equipment contact, dust and moisture and other sundries will affect the service life of the equipment; in addition, heat dissipation is achieved by adding electrical cooling equipment, although this method is effective but the cost is high, and it consumes a lot of electric energy , which also adds a lot of extra burden to the maintenance work of the unit
