So we're going to make a small wind generator. It can be made at home. 90% of the parts are made of plastic pipes and fittings, so it can be easily disassembled for transportation and reassembled. Let's start.
Manufacturing of blades
For this you will need a plastic pipe with a diameter of 8 cm and a length of 25 cm.
Cut it lengthwise into three equal parts. We cut each part lengthwise at an angle and cut out a blade from the resulting parts, as in the figure.
For the base of the screw, take any round plate with a diameter of 6 cm.
We make three equally spaced holes in it and, using small bolts and nuts, attach the blades to the plate.
Making the base
A propeller, generator, tail and turning mechanism are installed on the base and mast of the wind generator. The base is very easy to make. To do this you will need several short pieces of plastic pipe and some fittings.
We connect 4 bends and 3 tees, as in the figure.
Making a tail
For normal operation of a wind generator, a tail is needed. What is its purpose? The tail is needed to automatically rotate the propeller axis when the wind direction changes.
To make it, you need to cut out a plate of galvanized steel, make a slot in a plastic pipe, insert the plate into it and secure everything with a bolt.
Housing with generator
To make a housing with a generator you will need:
- electrical wire,
- plastic handle body,
- plastic tee,
- two bearings,
- 3 V DC motor (generator).
Insert the generator into the tee.
Secure the bearings to a common axis.
You can use a section of the handle body as an axis.
One bearing must be attached to the tee.
Mini wind generator is ready
Place the wind generator opposite the fan.
Connect the probes to the output wires. Yes, the device will show that electric current is being generated. With an efficient generator, you can charge a 3-volt battery. In addition, in a similar way you can make a larger wind generator that can be used to charge a mobile phone.
