Abstract

The invention relates to the technical field of wind power generating equipment, in particular to a sliding rod type wind turbine blade adjusting mechanism. An existing mechanism in the prior gear art has the problems that the torque is large, the reliability is poor, and the blade angle is difficult to control. The sliding rod type wind turbine blade adjusting mechanism comprises a driving motor fixing disk, an adjusting disk, a blade shaft, adjusting disk connecting joints, an adjusting disk connecting shaft, connectors, connector connecting pins, blade shaft connecting pins and a sliding rod mechanism. The adjusting disk connecting joints are evenly arranged on the outer lateral side of the adjusting disk, the connectors are connected with the adjusting disk connecting joints through the connector connecting pins, and connecting rods are in threaded connection to the connectors; sliding blocks are inserted into the connecting rods and connected with the ends of the blade shaft through the blade shaft connecting pins; and the adjusting disk is connected with a power outputting shaft of a driving motor. By means of changing the structure of the blade adjusting mechanism, a transmitting mode is changed, and the transmitting stability and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a sliding bar type wind rotor blade adjustment mechanism. Background technique [0002] The wind turbine blade adjustment mechanism is connected with the power unit to drive the main transmission gear to rotate, and the windward angle of the blade is adjusted through the transmission of the transmission mechanism. [0003] At present, the blades of wind turbines are either installed at a fixed angle, or the angle of each blade is adjusted independently. The independent adjustment of blade angle is poor in synchronization. [0004] In addition, the gear structure of a single-frame impeller disclosed in the invention patent application number 201410561011.7 and the utility model patent ZL201420608931.5 is not ideal in terms of blade angle control. As a result, the overall operation and unit power generation cost are still unsatisfactory. Contents of the ...
