Problems solved by technology

[0002] In the existing downwind wind turbines, since the wind rotor is located on the downwind side of the main engine and the tower pole, the main engine of the wind turbine tends to sway easily during operation due to the influence of factors such as wind changes and the tower shadow effect, resulting in unstable power output of the generator. Stable, low efficiency, and parts such as slewing bearings are easy to wear due to frequent work

Abstract

The invention discloses a downwind aerogenerator gyrodamping and locking mechanism which mainly comprises an anemoscope, a gear case, a motor, a small belt wheel, a big belt wheel, a synchronous belt and a pedestal flange, wherein the motor is connected with the small belt wheel by the gear case, the small belt wheel is connected with the big belt wheel by the synchronous belt, the big belt wheelis connected and fixed with the pedestal by bolts, a tension wheel is arranged on the supporting frame of the gear case, and the supporting frame is provided with a spring matched with the tension wheel. Rotational resistance is relatively large under the condition of no power supply, and speed change between the transmission of the gear case and the synchronous belt increases torque moment so asto achieve good damping effect. The invention has simple operation, and solves the problems of frequent swinging of a generator and unstable power output caused by the influence of wind change, towershadow effect and other factors in the power generation process of the downwind aerogenerator. The invention increases the work efficiency of the aerogenerator, reduces the wear degree of parts, and is more safe and convenient during maintenance.

Description

technical field [0001] The patent of the present invention relates to the technical field of wind power generator and mechanical transmission. Background technique [0002] In the existing downwind wind turbines, since the wind rotor is located on the downwind side of the main engine and the tower pole, the main engine of the wind turbine tends to sway easily during operation due to the influence of factors such as wind changes and the tower shadow effect, resulting in unstable power output of the generator. Stability, low efficiency, and parts such as slewing bearings are easy to wear due to frequent work. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a rotation damping and stop mechanism for the leeward wind turbine to improve the working efficiency of the downwind wind turbine and reduce the wear and tear of parts in order to solve the above-mentioned deficiencies in the technology. [0004] In order to achieve the ...
