Problems solved by technology

However, the pitch mechanism increases the failure rate of the fan
If the transmission chain in the pitch control mechanism breaks down, the blades will be in a state of free swing, and the blades may collide with the wind turbine tower during free swing, causing damage to the blades and wind turbines, resulting in large economic losses

Abstract

The invention provides a wind turbine blade buffering device. The device comprises a connecting component and a buffering component arranged on the connecting component. The buffering component comprises a metal framework and a detachable buffering pad arranged on the top surface of the metal framework, wherein a third buffering component is arranged in the metal framework. Damage of wind turbineblade free oscillation to a wind turbine generator system can be avoided, accordingly, economic loss is avoided, elastic deformation of the buffering pad, plastic deformation of the metal framework and the buffering capability of the third buffering component can be combined for improving the buffering capacity of the buffering device, and in addition, the effects of low impedance and high energyabsorption efficiency are achieved.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to the Chinese patent application CN201710371167.2 entitled "A Fan Blade Buffer Device" filed on May 24, 2017, the entire content of which is incorporated herein by reference. technical field [0003] The invention belongs to the technical field of wind power, and in particular relates to a fan blade buffer device. Background technique [0004] In large-scale wind turbines, the pitch control mechanism is often used to control the pitch of the blades. The pitch control mechanism controls the installation angle of the blades to change with the change of wind speed, so as to realize the speed adjustment before the generator is connected to the network and reduce the impact of the network. current, so that the output power can be kept relatively stable, which increases the power generation of the fan. However, the pitch control mechanism increases the failure rate of the fan. If the tran...
