Abstract

The invention discloses protection equipment for a wind driven generator, and relates to the technical field of wind power generation. The protection equipment comprises a wind driven generator main body, a power generation assembly, a hub and blades, a cavity is formed inside each blade, a cleaning pipe is arranged inside each cavity, a plurality of side wings are fixedly connected to the outer side of each blade, cleaning plates are arranged on the outer sides of the side wings and penetrate through the blades to be connected with the cleaning pipes, and ventilation cavities are formed in the cleaning plates. According to the protection equipment for the wind driven generator, when the wind driven generator main body operates, the stress area of the blades is increased through the side wings, the blades drive the cleaning plates to ascend and descend on the blades when rotating, frost and other impurities attached to the blades and the side wings can be cleaned, meanwhile, the blades rotate to drive external wind to enter the interiors of the cavities through air inlets and the ventilation cavities, and air flow in the cavities is driven to flow out through cleaning openings, so that dust adhered to the side wings and the blades is cleaned.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to protective equipment for wind power generators. Background technique [0002] At present, wind power generation technology is developing rapidly, and wind power generators are generally installed in open areas such as high mountains, border areas or coastal areas. Due to the remoteness of the area and the often harsh weather conditions, dust and foreign matter often accumulate on the surface of the wind turbine blades, or the surface of the blades is prone to icing in winter. As a result, it is easy to cause changes and differences in the weight of the fan blades, so that the balance between the fan blades cannot be well maintained, resulting in the vibration of the wind turbine during the rotation process, which affects the overall structural stability of the generator set; [0003] At the same time, the weight of the fan blade increases, which increases the load ...
