Preparation materials: a bamboo pole (length should be more than 2 meters), a cube of wood with a side length of 5 to 8 cm, some strong glue, some tape paper, a small motor, a propeller with a diameter greater than 18 cm, two Each wire is more than 2 meters long.
First, drill a hole in the center of the cube wooden block with a diameter just right to accommodate the bamboo pole, and insert the wooden block into one end of the bamboo pole (if the wooden block slides down, then Wrap a few circles of tape on the bamboo pole under the wooden block or fix it with strong glue. Then use strong glue to stick the small motor to one end of the wooden block so that the head of the wooden block is pushed outward. Then insert the propeller on the small motor and finally use two Connect the two wires to the positive and negative terminals of the motor respectively. Well, you're done.
Put the bamboo pole up where the wind is used, and the propeller will start to rotate. At this time, there will be an emission from the two wires. The strong current and voltage of 1 volt are almost equivalent to a battery, enough to make a small light bulb shine. If you make a few more such wind generators and connect them together, the voltage can be imagined!
Wind power generation fins are made of tensile fiberglass materials. According to relevant public information: tensile fiberglass blades are light, strong, corrosion-resistant, uniform in material, strong in flexibility, and tensile fiberglass reinforced blades have good performance. Durability and corrosion resistance: Resistant to acid, alkali, and atmospheric environment corrosion, no regular maintenance is required.
