Danger. The height of large windmills is generally about 100 meters, which is roughly equivalent to a high-rise building with a height of more than 30 stories. When there is strong wind, these large windmills that generate electricity must activate the braking mechanism to stop the windmills from rotating. However, the braking mechanism of one of the windmills failed, causing the windmill leaves to rotate rapidly in the wind. Because the windmill rotated too fast, the current generated by the generator inside was too large, causing a fire inside the generator. The generator on the windmill Part of it exploded, and with thick black smoke and raging fire, the entire top part was constantly falling apart. After the top collapsed, the bottom of the entire supporting part of the windmill was also broken by the strong wind, and the windmill completely collapsed.
Is there a wind power generation with N number of small spiral blades erected next to the fruit trees on the mountain?
Wind power generation:
Convert the kinetic energy of the wind into mechanical kinetic energy. Then convert mechanical energy into electrical kinetic energy, which is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of approximately three meters per second (the degree of breeze). Wind power is becoming a craze around the world because it does not require the use of fuel and does not produce radiation or air pollution.
The devices required for wind power generation are called wind turbines. This kind of wind turbine can be roughly divided into three parts: wind wheel (including tail rudder), generator and iron tower. (Large-scale wind power stations basically do not have tail rudders, and generally only small ones (including household types) have tail rudders)
The wind wheel is an important component that converts the kinetic energy of the wind into mechanical energy. It consists of two (or more) propeller-shaped impellers. When the wind blows towards the blades, aerodynamic force is generated on the blades to drive the wind wheel to rotate. The blade material requires high strength and light weight. Currently, it is mostly made of fiberglass or other composite materials (such as carbon fiber). (There are also some vertical wind wheels, S-shaped rotating blades, etc., which have the same function as conventional propeller-type blades)
Since the speed of the wind wheel is relatively low, and the magnitude and direction of the wind force often change, This in turn makes the speed unstable; therefore, before driving the generator, a gearbox must be attached to increase the speed to the rated speed of the generator, and a speed regulating mechanism must be added to keep the speed stable, and then connected to the generator. In order to keep the wind rotor always aligned with the wind direction to obtain maximum power, a tail rudder similar to a wind vane needs to be installed behind the wind rotor.
The iron tower is the structure that supports the wind wheel, rudder and generator. It is generally built relatively high in order to obtain larger and more uniform wind force and to have sufficient strength. The height of the tower depends on the impact of ground obstacles on wind speed and the diameter of the wind wheel. It is generally in the range of 6-20 meters.
The function of the generator is to transfer the constant rotation speed obtained from the wind wheel to the power generation mechanism through increased speed for even operation, thereby converting mechanical energy into electrical energy.
Yes, mountainsWind power generation with N number of small spiral blades erected next to the fruit trees. The tops of the blade columns of these small spiral blades are supported on the top of the bracket through bearings, and the top of the bracket is equipped with an air outlet channel; on the blade column A blade is provided, which is located in the bracket and spirals along the axial direction of the blade column.
