Wind-solar hybrid street light is a lighting device that combines solar and wind energy. The wind turbine is mainly responsible for collecting and converting wind energy into electrical energy. The rotation direction of the wind turbine is determined by the direction of the wind and the designed mechanical structure.
Generally speaking, the rotation direction of the wind turbine is opposite to the direction of the wind. When wind blows over the blades of a wind turbine, the force of the wind causes the blades to rotate. According to Newton's third law, the reaction force of the wind on the blades causes the entire wind turbine to rotate. Therefore, the rotation direction of the wind turbine is opposite to the direction of the wind.
In addition, the rotation direction of the wind turbine is also affected by the designed mechanical structure. Generally speaking, the rotor of a wind turbine is connected to the generator through a transmission device. The transmission device can determine the direction of rotation according to design needs. For example, if the transmission is geared, the wind turbine may turn in the same direction as the wind or in the opposite direction, depending on the design of the gears.
In general, the rotation direction of the wind turbine is opposite to the direction of the wind, but the specific rotation direction is also affected by the designed mechanical structure. The wind turbine in the wind-solar hybrid street lamp will determine the direction of rotation according to the design needs to maximize the collection and conversion of wind energy into electrical energy and provide sustainable energy for street lamp lighting.
