Abstract

The invention provides a connecting rod type wind turbine blade adjusting mechanism and a using method. The connecting rod type wind turbine blade adjusting mechanism comprises a power unit of which a main shaft is horizontally arranged, a machine base, a driving motor fixing plate, a cabin cylinder wall, a front end cover, a coupler, a supporting mechanism, a screw-nut mechanism, a sliding mechanism and a connecting rod mechanism. The coupler is connected with the driving motor fixing plate and the supporting mechanism. The sliding mechanism is connected with the screw-nut mechanism. The connecting rod mechanism is fixed to the sliding mechanism. By changing the structure of the blade adjusting mechanism and changing the transmission mode, the blade shake quantity is reduced, and the stability and accuracy of transmission are improved.

Description

technical field [0001] The present application relates to the technical field of wind power generation equipment, and in particular to a link-type wind rotor blade adjustment mechanism and a method of using the same. Background technique [0002] The blade is the core component that converts wind energy into mechanical energy in the process of wind power generation. The wind turbine blade adjustment mechanism is connected with the power unit to drive the main transmission part to move, and the windward angle of the blade is adjusted through the transmission of the transmission mechanism. [0003] At present, some wind turbine blades are installed at a fixed angle, and some are independently adjusted for the blade angle. However, the adjustment mechanism of the current gear technology has problems such as large torque, poor reliability, difficult to control the blade angle, and large amount of blade shaking caused by the gear tooth clearance. These problems need to be solved ...
