Problems solved by technology

In addition, the transport and storage of the protective film is also very laborious
It is easy to be damaged during transportation and hoisting. Blistering, edge roll-up, and weathering and displacement of the protective film at the tip of the blade often occur during the operation of the blade. Generally, the service life of the protective film is 4-5 years, and the replacement cost in the later period is even higher. high

Embodiment

[0028] The present invention provides a wind turbine blade leading edge protection device with a spoiler structure, which includes a protection device body 2 installed on both sides of the blade leading edge 1, the shape of the protection device body 2 is the same as that of the blade leading edge 1, and the protection device The device body 2 is pasted on the axial length of the leading edge 1 of the blade, and the outer surface of the protection device body 2 is provided with at least two protrusions 3 . The material of the protective device body 2 is one of ABS, PP, ASA, PPS, PU, ​​polyester and polypropylene. In order to avoid using metal products to cause lightning, use anti-wind and sand, anti-ultraviolet high-strength plastic products. The length of the protective device body 2 is less than 500mm. The optimum length is 200mm, installed through multiple protective device bodies. The main body of the protection device is located at the leading edge of the blade, especial...

Abstract

The invention discloses a wind power blade leading edge protection device with a turbulent flow structure, which comprises protection device bodies arranged on two sides of a blade leading edge, the shape of the protection device bodies is the same as that of the blade leading edge, the protection device bodies are adhered on the axial length of the blade leading edge, and the turbulent flow structure is arranged on the protection device bodies. At least two protrusions are arranged on the surface of the outer side of the protection device body. According to the wind power blade front edge protection device with the turbulent flow structure, the front edge of the blade can be protected against damage for a long time, the airflow stagnation phenomenon is prevented, a larger stall attack angle is allowed, airflow on-way losses are reduced, and the generating capacity is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power blade leading edge protection device with a spoiler structure and an installation method. Background technique [0002] Generally, during the operation of wind power blades, the rotational speed of the local section increases linearly with the increase of the blade length, resulting in a relatively large linear velocity at the tip of the blade. At present, the running speed of the tip of the mainstream blade is about 85m / s, that is, 306km / h, this speed is similar to the speed of high-speed rail. Relatively large speeds will be eroded by particles in the air around the blades, including raindrops, hail, salt spray, sand and gravel, etc. This is the leading factor that causes damage to the leading edge of the blades. Others such as ultraviolet rays and moisture can also cause blade aging . When the leading edge of the blade tip is damaged, the flowing ...
