Description of manufacturing method and steps of windmill

The manufacturing method and steps of the windmill are as follows:

Materials: colored paper, sticks, scissors, nails.

1. Prepare a square colored paper, a nail, a wooden stick and a pair of scissors with your favorite color.

2. First, fold it twice along the diagonal of the square colored paper.

3. then expand. Next, use scissors to cut the four sides along the crease of the square colored paper, but don't cut it.

4. Then use nails to fix the cut colored paper together and fix the colored paper.

5. Finally, the fixed colored paper and the stick can be fixed together, and a small hand-made windmill will be finished.

Uses and characteristics of windmills

First, the use:

1. bird repeller for power facilities: Windmills can be used to repel birds on power facilities and prevent them from nesting on power lines, thus avoiding short circuit or electric shock accidents.

2. Power generation: The most common use of windmills is power generation. Windmills convert wind energy into mechanical energy, and then generators convert mechanical energy into electrical energy. Wind power generation has the advantages of environmental protection, renewable and low operating cost, so it has been widely used in the world.

3. Irrigation: Windmills can also be used to irrigate farmland. Through the mechanical energy of the windmill, the water source can be lifted to a high place, thus irrigating more farmland.

4. Aquaculture: In coastal areas, windmills are used to drive pumps, and seawater is introduced into aquaculture ponds to provide a suitable living environment for fish.

5. Industrial application: In some industrial fields, windmills are also used to drive mechanical equipment, such as flour mills and chemical plants.

Second, the characteristics:

1. Efficiency: Windmills can be driven by wind energy, which is a renewable energy source, so windmills have high efficiency and can reduce dependence on traditional energy sources.

2. Environmental protection: the windmill will not produce pollutants during use, which is an environmentally friendly way of energy utilization.

3. Renewable: Wind energy is a kind of renewable energy, so the windmill is renewable and can continuously provide energy during continuous use.

4. Extensiveness: Windmills can be widely used in various fields, such as electric power, irrigation, aquaculture and industrial applications.

5. Simple structure: The structure of the windmill is relatively simple, mainly composed of blades, hubs, towers and other parts, so its manufacturing cost is relatively low.
