Environmental pollution is still quite serious nowadays and has become mainstream. Everything is moving in the right direction! In the past, we generated electricity using coal, but this would pollute the atmosphere. Therefore, wind turbines were invented. Today, we are going to make a simple wind turbine. All the materials used are very common. A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. The working principle of a wind turbine is relatively simple. Under the action of wind force, the wind wheel rotates, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.

A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine is generally composed of components such as the wind wheel, generator (including the device), reversing device (tail fin), tower, speed-limiting safety mechanism and energy storage device.
The working principle of a wind turbine is relatively simple. Under the action of wind force, the wind wheel rotates, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.

For many centuries, wind turbines, like hydraulic machinery, have served as a power source to replace human and animal power, playing a significant role in the development of productive forces. The wide application of modern electromechanical power and the discovery of oil fields in the Middle East in the 1950s slowed down the development of wind turbines.

In the early 1970s, due to the "oil crisis", the problem of energy shortage emerged. People realized the instability and limitation of conventional mineral energy supply, and thus seeking clean and renewable energy became an important issue in the modern world. Wind energy, as a renewable and natural energy source, has once again drawn people's attention.

It is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a thermal energy utilization engine that takes the sun as the heat source and the atmosphere as the working medium. Wind power generation utilizes natural energy. It is much better than diesel power generation. However, if it is used in an emergency, it is still not as good as a diesel generator. Wind power generation cannot be regarded as a backup power source, but it can be utilized for a long time.

The principle of wind power generation is to use wind to drive the rotation of wind turbine blades, and then increase the rotational speed through a speed increaser to drive the generator to produce electricity. According to current wind turbine technology, a gentle breeze speed of approximately three meters per second (the intensity of a gentle breeze) is sufficient to start generating electricity.

Wind power generation is creating a craze around the world because it has no fuel issues and does not produce radiation or air pollution.

Wind power generation is very popular in Finland, Denmark and other countries. Our country is also vigorously promoting it in the western regions. The small-scale wind power generation system is highly efficient, but it is not composed of just one generator head. Instead, it is a small system with a certain technological content: wind turbine + charger + digital inverter. A wind turbine is composed of a head, a rotating body, a tail fin and blades. Each part is very important. The functions of each part are as follows: The blades are used to receive wind power and convert it into electrical energy through the head of the machine; The tail fin keeps the blades always facing the direction of the incoming wind, thereby obtaining a large amount of wind energy. The rotating body enables the nose to rotate flexibly to achieve the function of adjusting the direction of the tail fin. The rotor of the machine head is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electrical energy.

Due to the unstable air volume of wind turbines, the output of alternating current varies from 13 to 25 volts. It needs to be rectified by a charger and then charged to the battery to convert the electrical energy generated by the wind turbine into chemical energy. Then, an inverter power supply with a protection circuit should be used to convert the chemical energy in the battery into AC 220V mains power to ensure stable operation.

Mechanical connection and power transmission: The horizontal shaft fan blades are connected to the transmission shaft of the generator through the gearbox and its high-speed shaft with an elastic coupling, transmitting the torque to the transmission shaft of the generator. This coupling should have excellent damping and vibration absorption characteristics, which are manifested as absorbing an appropriate amount of radial, axial and certain angular offsets, and the coupling can prevent the mechanical device from overloading. Another type is the direct drive type of fan motor, where the blades are directly connected to the motor without going through a gearbox

Before assembly, please check whether the circuit is unobstructed, whether the components on the circuit are complete, and whether all contact points are in good contact. During the assembly process, be careful not to get the glue on your clothes or skin. Accessories should be kept out of reach of younger siblings to prevent accidental swallowing of parts! Don't play with it on your head, or the model might fall and hurt you!
