The core components of a wind turbine, such as the generator, gearbox and converter, are basically installed inside the nacelle to protect the core components from external environmental factors such as wind and sand. At the same time, it is also necessary to ensure that each component in the nacelle has a certain heat dissipation effect.

[0003] The existing structure of the nacelle cover has poor dust protection effect at the air inlet connected to the outside. Dust can easily enter the nacelle cover, causing serious wear and tear on the mechanical and electronic components of the wind turbine, resulting in huge economic losses. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a nacelle cover of a wind turbine generator set is designed to prevent sandstorms, including a cover body, air inlet holes and heat dissipation holes are respectively opened on both sides of the cover body, a filter plate is installed on the outer side of the air inlet hole, a heat dissipation pipe is connected to the outer side of the heat dissipation hole, a connecting plate is provided in the inner cavity of the cover body, the center of the connecting plate and the center of the heat dissipation pipe are on the same horizontal line, a connecting rod is fixedly connected between the connecting plate and the top of the inner cavity of the cover body, a driving motor is installed at one end of the connecting plate, a driving shaft is installed at the driving end of the driving motor, a rubber spiral leaf is fixedly connected to the outer side of the driving shaft, the outer side of the rubber spiral leaf is attached to the inner wall of the heat dissipation pipe, a first fan blade is installed on the driving shaft between the rubber spiral leaf and the connecting plate, and a plurality of second fan blades are installed on the driving shaft inside the rubber spiral leaf.

[0006] Preferably, a plurality of heat dissipation copper plates penetrate the outer side of the heat dissipation pipe, and the plurality of heat dissipation copper plates are all hollow structures, and a conduit is connected between two adjacent heat dissipation copper plates among the plurality of heat dissipation copper plates. A cooling water tank is installed on the top of the cover body, and a circulating pump is installed in the cooling water tank. The water outlet end of the circulating pump is connected to a water outlet pipe, and the water outlet pipe penetrates the cooling water tank and is connected to one of the conduits, and a circulating pipe is connected between the conduit and the cooling water tank.

[0007] Preferably, a plurality of first fixing bolts penetrate the filter disc, and the plurality of first fixing bolts are all threadedly connected to the surface of the cover body.

When the generator set is working, the drive motor is started to cooperate with the drive shaft to drive the rubber spiral blade, the first blade and the second blade to rotate, so that the first blade rotates to blow the heat of the cover body to the heat dissipation pipe, and then the rubber spiral blade pushes the heat outwards through the heat dissipation pipe to gradually discharge the heat from the cover body. At the same time, the rotation of the second blade can assist in the heat dissipation of the heat in the heat dissipation pipe. Since the rubber spiral blade is fitted with the inner wall of the heat dissipation pipe, and the air is filtered by the filter plate outside the air inlet, a large amount of sand is prevented from entering the generator set in the cover body from the heat dissipation hole and the air inlet hole during a sandstorm to cause wear.

[0013] When heat is dissipated, starting the circulation pump in conjunction with the water outlet pipe, the conduit and the circulation pipe can make the cooling water in the cooling water tank flow in the heat dissipation copper plate to dissipate the heat of the heat dissipation copper plate, thereby improving the heat dissipation effect of the cover body.

A circulation pipe 32 is connected between the conduit 210 and the cooling water tank 3. When the generator set is working, the drive motor 26 is started to cooperate with the drive shaft 21 to drive the rubber spiral blade 22, the first fan blade 27 and the second fan blade 23 to rotate, so that the first fan blade 27 rotates to blow the heat of the cover body 1 to the heat dissipation pipe 2, and then the rubber spiral blade 22 pushes the heat outward through the heat dissipation pipe 2 to gradually discharge the cover body 1.
