So, we are going to make a small wind generator. It can be made at home. 90% of parts are made of plastic pipes and fittings, so it can be easily disassembled for transportation and reassembled. Let's start.
For this you need a plastic pipe with a diameter of 8 cm and a length of 25 cm. Cut it along into three equal parts. Each part is cut along at an angle and we cut the blade out of the parts obtained, as shown in the picture. For the base of the screw, we take any round plate 6 cm in diameter. We make three equidistant holes in it and fasten with small bolts and nuts blades toplate.
Making the Basics
A screw, generator, tail and turning mechanism are installed on the basis and mast of the wind generator. The basis is very simple. To do this, you need a few short pieces of plastic pipe and some fitting elements. 4 branches and 3 tees are connected as in the picture.
Make a tail
For normal operation of a wind generator you need a tail. What is his purpose? The tail is needed to automatically rotate the axis of the screw when the wind direction changes. For its manufacture, you need to cut a plate made of galvanized steel, make a cut in a plastic pipe, insert a plate into it and fasten everything with a bolt.
Housing with a generator
For the manufacture of housing with a generatoryou need:
plastic handle housing,
3 V DC motor (generator).
Insert the generator into the tee. Fix the bearings on a common axis. As an axis, you can use a segment of the handle body. One bearing should be attached to tee.
Mini wind turbine ready
Place the wind generator in front of the fan. Connect the probes to the output wires. Yes, the device will show that electrical current is generated. With an efficient generator, you can charge a 3-volt battery. In addition, in this way you can make a bigger wind turbine that can be used to charge a mobile phone.
