Wind driven generator pitch varying training platform

Abstract

The invention discloses a wind driven generator pitch varying training platform. The platform is characterized in that a fixing plate, a driving device, a transmission device and a movement mechanismare arranged in a rack; the driving device is fixedly connected with the fixing plate; the transmission device is connected with the driving device; the movement mechanism is connected with the transmission mechanism; the movement mechanism comprises a pointer, a lead screw, a lead screw nut, a sliding rod and a sliding block; the lead screw is vertically connected with the fixing plate; the leadscrew nut is screwed to the lead screw; the pointer is fixedly connected with the lead screw nut; one side of the pointer is provided with a graduation ruler; the graduation ruler is arranged in parallel with the lead screw; the sliding rod is arranged in parallel with the lead screw; the sliding block is slidably connected with the sliding rod; and the pointer is fixedly connected with the sliding block. According to the wind driven generator pitch varying training platform of the invention, since the sliding rod and the lead screw are arranged in parallel, when the lead screw rotates, the lead screw drives the lead screw nut to move along the axis of the lead screw, so that the pointer can be driven to move along the axis of the lead screw, and a pitch varying angle is reflected on the graduation ruler indicated by the pointer, and the requirements of indoor teaching can be satisfied.

Description

technical field [0001] The invention relates to the field of pitch-changing training for wind-driven generators, in particular to a pitch-changing practical training platform for wind-driven generators. Background technique [0002] As one of the core parts of the control system of large-scale wind turbines, the pitch control system plays a very important role in the safe, stable and efficient operation of the turbine. By adjusting the pitch angle of the blades, the angle of attack of the airflow on the blades is changed, thereby controlling the aerodynamic torque and aerodynamic power captured by the wind rotor. [0003] Due to the large overall size of the wind turbine, the diameter of the wind rotor is about 80 meters, the installation height is relatively high, and the height of the tower is also about 80 meters, so it is impossible to directly install the wind turbine as a whole in the school or factory building, which greatly Limiting the teaching of pitch systems in ...
