Problems solved by technology

[0003] However, at present, when performing maintenance on small and medium-sized wind turbines, due to the diameter of the tower, it is impossible to build a ladder passage from the inside, and can only use external equipment to enter the interior of the nacelle cover. Generally, a large crane is used to send workers to the wind turbine. , and then the workers open the hatch of the nacelle cover and enter the interior. This method is not only risky, but also has high requirements on the meteorological environment. Open the hatch, and the terrain requirements are high, and large cranes cannot enter areas with complex terrain

Abstract

The invention provides a novel wind driven generator cabin cover which comprises a crawling ladder arranged on the side surface of a tower column, a leading-in ladder fixedly connected with the cabin cover and communicating with a cabin door of the cabin cover and a switching ladder fixed to the leading-in ladder and arranged at the outer side of the crawling ladder, and workers enter the leading-in ladder through the switching ladder. According to the novel wind driven generator cabin cover, through the scheme design of the crawling ladder, the switching ladder and the leading-in ladder, the maintenance problem of small and medium-sized wind driven generators is effectively solved, the cost is low, the influence on the dynamic performance of the wind driven generators is very small, and the maintenance cost and the efficiency of the small and medium-sized wind driven generators are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power generator nacelle cover, and in particular relates to a novel wind power generator nacelle cover. Background technique [0002] In order to facilitate the maintenance of the current large-scale wind power generators, a ladder passage is built inside the tower column, and the nacelle cover is entered from the inside of the tower column, and then the electrical equipment inside the nacelle cover is overhauled. [0003] However, at present, when performing maintenance on small and medium-sized wind turbines, due to the diameter of the tower, it is impossible to build a ladder passage from the inside, and can only use external equipment to enter the interior of the nacelle cover. Generally, a large crane is used to send workers to the wind turbine. , and then the workers open the hatch of the nacelle cover and enter the interior. This method is not only risky, but also has high requirements on the ...
