Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a wind turbine impeller balancing and adjusting device. Background Art

[0002] In the existing wind power generation technology, the wind power system is mainly composed of three core components: the tower, the chassis and the impeller. The chassis, as the center of the entire system, is firmly installed on the top of the tower, while the impeller is rotatably installed on one end of the chassis through precise bearings and transmission devices. This design enables the wind turbine to effectively capture wind energy and convert it into electrical energy.

[0003] However, in actual operation, when working under strong winds or extreme weather conditions, the torque generated by the rotation of the impeller may cause the pressure of the chassis on the tower to increase significantly due to the dual influence of wind force and its own gravity. In contrast, the other end of the chassis is under less pressure. This uneven pressure distribution can easily cause the chassis to tilt, which in turn causes the impeller to be unbalanced. The unbalanced impeller will not only reduce the power generation efficiency of the wind turbine and increase energy consumption, but may also accelerate the wear of mechanical components, shorten the service life of the equipment, and pose a serious threat to the stability and safety of the entire system.

By placing a counterweight assembly 4 on the chassis 2, and the counterweight assembly 4 and the impeller 3 are respectively arranged on both sides of the chassis 2, when encountering strong winds or extreme weather, when the pressure sensor 5 located between the chassis 2 and the tower body 1 detects that the pressure on the tower body 1 from both sides of the chassis 2 is unbalanced, the background system will calculate the distance that the counterweight assembly 4 should be away from or close to, and then the counterweight assembly 4 will be adjusted through the adjustment assembly 6 to keep the pressure on the tower body 1 from both sides of the chassis 2 balanced, which is beneficial to improving the stability of the entire system and reducing the risk of failure caused by tilt or imbalance.
