The principles of the semi-submersible wind turbine model are wind energy conversion, mechanical energy conversion, and electrical energy transmission.
1. Wind energy conversion: When the wind passes through the blades, the blades are affected by the wind and begin to rotate. During the rotation, the kinetic energy of the wind is converted into the kinetic energy of the blades.
2. Mechanical energy conversion: The rotation of the blades will drive the rotating shaft to rotate the generator, and the generator uses the rotating mechanical energy to convert into electrical energy.
3. Electric energy transmission: The electric energy generated by the generator is processed by transformers and other equipment, and then transmitted to the power grid for power supply.
Mold casting is casting with a model. For example: first use wood to make a "model" that is exactly the same as the "product" according to the drawing, then bury the "model" in a sand pit and then take it out, so that there is a "space" in the sand pit that is exactly the same as the "product". Then melt the product material and pour it into this space, condense it into a solid, and then take it out, and you will get a product. This production method is called mold casting.
