The horizontal and pitching direction movement mechanism consists of a horizontal movement reduction gearbox, a pitching movement reduction gearbox, a DC motor, a proximity switch and a micro switch. When the DC motor rotates, the horizontal movement reduction gearbox drives the photovolt*c cell array to move horizontally to the east or west, and the pitching movement reduction gearbox drives the photovolt*c cell array to move in a pitching direction to the north or south.

3. Wind power supply device
(1) Composition of wind power supply device
The wind power supply device m*nly consists of blades, hub, generator , nacelle, t*l rudder, crosswind yaw control mechanism, DC motor, tower and foundation, tachometer, tachometer bracket, axial flow fan, axial flow fan bracket, axial flow fan frame, single-phase AC motor, capacitor, wind field motion mechanism box, guardr*l, connecting rod, roller, universal wheel, micro switch and proximity switch, as shown in Figure 3.
The blades, hub, generator, nacelle, t*l rudder and crosswind yaw control mechanism are assembled into a horizontal axis permanent magnet synchronous wind turbine generator and installed on the tower. The wind farm is composed of an axial flow fan, an axial flow fan bracket, an axial flow fan frame, a tachometer, a tachometer bracket, a wind farm motion mechanism box, a transmission gear ch*n mechanism, a single-phase AC motor, a roller and a universal wheel. The axial flow fan and the axial flow fan frame are installed on the upper part of the wind farm motion mechanism box, and the transmission gear ch*n mechanism, the single-phase AC motor, the roller and the universal wheel constitute the wind farm motion mechanism. When the single-phase AC motor in the wind farm motion mechanism rotates, the transmission gear ch*n mechanism drives the roller to rotate, and the wind farm motion mechanism box performs a circular rotation around the tower of the wind turbine. When the axial flow fan delivers variable *r volume, a wind field with variable wind direction and wind speed is formed around the wind turbine.
In a variable wind farm, the wind turbine uses the t*l rudder to achieve passive yaw to face the wind, so that the wind turbine outputs maximum electrical energy. The speed meter detects the wind volume in the wind farm. When the wind volume in the wind farm exceeds the safety value, the sidewind yaw control mechanism is activated to make the t*l rudder 45° sidewind, and the wind turbine blade speed slows down. When the wind volume in the wind farm is too large, the t*l rudder is 90° sidewind, and the wind turbine is in a braking state.
4. Wind power supply system
(1) Composition of wind power supply system
The wind power supply system m*nly consists of a wind power supply control unit, a wind power output display unit, a touch screen, a wind power supply control unit, a DSP control unit, an interface unit, a Siemens S7-200 PLC, a relay group, a terminal block, an adjustable resistor, a circuit breaker, a mesh frame, etc.
(2) Control method The
yaw function of the wind power supply control unit has two states: manual and automatic, and can perform manual or automatic variable wind direction operation.
Variable wind volume is achieved by controlling the axial flow fan with a frequency converter. Manually operate the relevant buttons on the inverter operation panel to change the inverter output frequency between 0-50Hz, and the axial flow fan speed changes between 0 and the rated speed to achieve variable *r volume output.
(3) DSP control unit and side wind yaw
The wind turbine rotor blades generate torque under the action of *rflow to drive the wind turbine to rotate, and the torque is input into the transmission system through the hub. When the wind speed increases to exceed the rated wind speed, the wind turbine rotor speed is too fast, and the generator may burn out due to overload.
For fixed-pitch wind turbines, when the wind speed increases to exceed the rated wind speed, if the *rflow separates from the blades, the wind turbine blades will be in a "stall" state, and the wind turbine will not burn out due to overload.
For variable-pitch wind turbines, when the wind speed increases, the angle of attack of the *rflow on the blades can be adjusted according to the change in wind speed. When the wind speed exceeds the rated wind speed, the output power can be stably m*nt*ned at the rated power. Especially in strong winds, the wind turbine is in a feathering state, which greatly improves the stress condition of the blades and the entire machine.
Most small wind turbines have fixed pitch rotors. In strong winds, sidewind yaw control is used to separate the *rflow from the blades, so that the rotor blades are in a "stall" state, safely protecting the wind turbine. In addition, the wind turbine can also m*nt*n a constant power output through sidewind yaw control.

The AC speed control system consists of a frequency converter and a three-phase AC motor. The output AC220V power supply of the inverter is the input power supply of the frequency converter. The frequency converter converts the single-phase AC220V into three-phase AC220V for use by the three-phase AC motor. The AC220V power supply of the inverter power control unit is provided by the inverter, and the DC24V output by the inverter power control unit is used for the LED stage lighting module.
