Abstract

The embodiment of the invention provides a blade, a load adjusting assembly, a wind generating set and a load adjusting method. The blade comprises a blade body and a load adjusting assembly, a mounting hole is formed in the position, close to the front edge, of the blade body, and the mounting hole penetrates through the windward side and the leeward side of the blade body; The load adjusting assembly is arranged in the mounting hole and comprises a flow guide adjusting piece with the length adjustable in the axial direction of the mounting hole and two covering parts connected to the two ends of the flow guide adjusting piece in the axial direction, so that the two covering parts can cover the two ends of the mounting hole through the flow guide adjusting piece; or the two covering parts extend out of the mounting hole, so that airflow can pass through the mounting holes to circulate between the windward side and the leeward side. According to the embodiment of the invention, the effective working time of the blade can be prolonged, and the blade can solve the problem that the blade of the wind generating set cannot adapt to extreme working conditions.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a blade, a load adjustment assembly, a wind power generating set and a load adjustment method. Background technique [0002] The blades of wind turbines are the key components to capture wind energy. As the length of the blades increases, the loads generated by the blades themselves and transmitted to other components of the unit increase. In order to ensure the safety of the unit, all components of the unit tend to be bulky. direction. The existing technology mainly adopts control strategies to sacrifice a certain amount of power generation in exchange for a relatively low load. That is, in extreme working conditions, when the load on the blade is high, in order to ensure the service life of the blade, the unit is usually in a shutdown state. As a result, the applicability of wind turbines is weak, and wind turbines are not fully used. [0003] Therefore, there i...
