Abstract
The utility model relates to a step-starting wind wheel and main shaft structure of a wind generation set. The step-starting wind wheel and main shaft structure comprises a generator main shaft and a wind wheel; upper and lower supporting plates of the wind wheel are connected with the generator main shaft by bearings; and the wind wheel is connected with the generator main shaft by a buffer component to drive the generator main shaft to rotate. According to the structure, the wind wheel and the generator main shaft are made into independent moving mechanisms, the wind wheel can be started generally at the start wind speed of 0.8 meter per second, and the wind wheel accumulating energy can easily drive the main shaft and a generator rotor to run and generate power; and the running stability of a generator is improved, and the service life of the generator is prolonged.
Description
Technical field
The utility model relates to the wind power equipment technical field, relates in particular to a kind of wind wheel structure of wind turbine component level starting.
Background technique
Existing wind-powered electricity generation unit all is that wind wheel, main shaft, generator etc. are rigidly connected, when starting, need wind wheel, main shaft, generator to promote together, this moment, resistance was larger, need the wind speed of startup just large, horizontal axis generally needs 3-4 meter per second wind speed to start, and vertical shaft generally needs 1.5 meter per second wind speed to start.
The model utility content
The purpose of this utility model is as overcoming the defective of prior art, and a kind of wind wheel structure of wind turbine component level starting is provided.
For achieving the above object, the utility model is by the following technical solutions: a kind of wind wheel structure of wind turbine component level starting, comprise generator shaft, wind wheel, the upper and lower supporting plate of described wind wheel is connected by bearing with generator shaft, and wind wheel is connected the drive generator shaft by buffer unit and rotates with generator shaft.
Described buffer unit is a spring, and an end of described spring is fixedly connected with on the generator shaft, and the other end is fixedly connected on the bottom plate of wind wheel.
Described shock absorber comprises the collar that is fixedly connected with the wind wheel top plate, and the half of sidewall of the described collar has draw-in groove,
Described generator shaft is fixedly connected with an axle, and described axle activity is stuck in the draw-in groove of the collar.
The utility model beneficial effect compared with prior art is: 1) wind wheel and generator shaft are made the mechanism of self-movement, the weight of wind wheel only has 1/5th of main shaft, generator amature weight, generally need the startup wind speed of 0.8 meter per second can start wind wheel, the wind wheel behind the savings energy can easily drive main shaft, generator amature running generating; 2) stationarity of increase generator operation, the life-span of prolongation generator.
