Problems solved by technology

[0006] To sum up, at present, the main method for reducing noise of large wind turbines is to glue sound-absorbing materials (such as mineral wool board, foam plastic, etc.) inside the nacelle cover. This method does not change the material of the nacelle cover shell. Structure, sound insulation and noise reduction effect is limited
At the same time, the above-mentioned sound insulation materials have the performance of heat insulation and heat preservation, and they are simply pasted on the inner wall of the nacelle, which will have harmful effects on wind turbines installed in high temperature areas

Embodiment 1

[0028] This embodiment is suitable for the nacelle cover of the 1.5MW wind power generating set in the cold temperate zone. Such as figure 1 , figure 2 As shown, a sound-proof and noise-reducing wind turbine nacelle cover, which includes a decorative protective surface layer 1, an FRP outer panel 2, a sandwich layer 3, an FRP inner panel 4, a rigid foam inner core 5, and a gradient density foam 6. Foamed plastic crust layer 7 and reinforced frame 8; the decorative protective surface layer 1 is attached to the outside of the FRP outer panel 2; the inner side of the FRP outer panel 2 is a sandwich layer 3, and the inner side of the sandwich layer 3 is attached to the FRP inner panel 4 on the outer side; the gradient density foam plastic 6 is attached on the inner side of the FRP inner panel 4, and the foamed plastic crust layer 7 is attached on the inner side of the gradient density foam plastic 6; on the inner side of the FRP inner panel 4, several reinforcement frames are al...

Embodiment 2

[0041] This embodiment is a wind power generating set working in a hot temperate zone. Such as figure 2 , image 3 As shown, the difference between this embodiment and Embodiment 1 is that a forced ventilation port 9 is provided on the original sound-proof and noise-reducing wind turbine nacelle cover to ensure ventilation at high temperatures. The internal temperature of the lower nacelle cover meets the working requirements of the generator set.

Abstract

The invention relates to a main component of large wind power generation equipment, in particular to a sound insulation and noise reduction type cabin cover of a wind power generator, comprising a decorative protecting surface layer, an FRP outer plate, a sandwich layer, an FRP inner plate, a hard foam plastic inner core, foam plastics with gradually changed density, a foam plastic skinning layerand a reinforcing frame, wherein the FRP outer plate, the sandwich layer, the FRP inner plate and the reinforcing frame form an integral frame by continuous formation, and the FRP outer plate, the sandwich layer, the FRP inner plate, the foam plastics with gradually changed density and the reinforcing frame form an integral structure. The invention provides the cabin cover of the wind power generator, which has good sound insulation and noise reduction functions, and heat insulation or temperature keeping and flame retardant performance and is suitable for high temperature and cold areas.

Description

technical field [0001] The invention relates to main components of large-scale wind power generating equipment, in particular to a sound-proof and noise-reducing wind power generator nacelle cover. Background technique [0002] In recent years, with the decrease of fossil fuels such as oil and coal and the continuous enhancement of people's awareness of environmental protection, the use of renewable energy such as solar energy, wind energy and water energy will gradually become a substitute and supplement for traditional energy. Since the beginning of the 21st century, with the improvement of wind power generation technology, in order to reduce the cost of power generation and transmission and improve economic benefits, large wind power generators (≥1.5MW) have become the mainstream models of wind power generation. It has also gradually shifted from the remote open areas where wind power was used in the early days to more populated electricity-consuming areas. With the incr...
