Vertical wind generator with own hands. Homemade vertical wind generator: circuit

Alternative energy is developing at a very fast pace. For example, a vertically-axial wind generator is no longer a novelty. In the near future renewable sources can essentially replace standard stations. They have a lot of advantages. For example, a vertical wind generator with its own hands is easy to make, it is not very expensive. As for its manufacture you can use improvised materials. As for the installation of such an assembly, then we should already consider where to perform it. Perhaps, in your case, the installation of the structure would be inappropriate.

What is the product?

The presented design is a special generator for generating electric energy by moving air currents (wind). In appearance, the device resembles a conventional mill with blades and a high mast, at the base of which is the generator itself. Naturally, such a device should not only be properly designed, but also correctly equipped.

The movement of the "wings" is provided by the wind, so the energy source is renewable. The higher the mast, the more power generation will be more stable and higher. Naturally, for the manufacture of such a device will require certain materials and devices for converting AC to DC. How can you make a vertical wind generator your own hands, you will learn later. The main thing is to have patience and a desire to work.

Spheres of application of construction

Basically, such an aggregate is installed during the construction of power plants. However, sometimes economical owners use it at home. You can use this device in the city and in the countryside. In order to build a whole power plant, it will take a fairly large area and lots of windmills.

The energy generated in this way can flow to meet the needs of private consumers or the industry. Naturally, in the latter case, you need to consider the economic feasibility of using such a source of electricity.

Advantages

Before you make a vertical wind generator with your own hands, you must definitely find out its advantages. Among them are:

- Low operating costs, easy installation and maintenance. All this you can do yourself. To do this, you do not need a lot of time or money.

- You can construct a vertical wind generator with your own hands.

- Quick installation. The main thing is that the device is fixed firmly, so that the force of the wind does not break it.

- Safety for the environment, as the generation of such energy is not accompanied by harmful emissions and does not require the disposal of waste materials. In addition, the source is renewable, so you should not be afraid that the resources will end.

- The possibility of using a sufficiently large area occupied by a similar power plant, for the cultivation of agricultural products.

- Saving money. First, the cost of such electricity does not depend on the dollar exchange rate or market prices for standard fuel. Secondly, you do not need to extract and process raw materials. Thirdly, the design is installed near the consumer, so there are no additional costs for the transportation of electricity. In addition, the wind does not need to buy from other countries that can inflate the price.

Disadvantages of the device

Before you make a wind generator, you also need to consider all the disadvantages that accompany its use:

- A considerable cost of construction, which was manufactured industrially. This defect is easily eliminated, since you can build a mast and blades from improvised means. Naturally, the quality of the result in both cases can be different. Therefore, it is worth determining whether you can design the unit yourself.

- Low prevalence of products, which generates a lot of conjecture about their work and effectiveness.

- The design produces a sufficiently high level of noise, and can also affect the quality of transmission of television or radio signals. Much depends also on the distance from the house to the windmill.

- The wind is an unstable source of energy, because the weather can be quiet. In this case, the generator will simply be useless.

- The only negative impact on the environment is that birds can fall into the blades and die.

- In some cases, when installing a windmill, the aesthetic view of the landscape suffers, although for the minimalists this is not a problem.

"It takes a lot of territory to install the power plant."

Classification of aggregates

Before you make a wind generator, you need to understand how it happens. The following types of structures can be distinguished:

1. With cylindrical blades. Such an aggregate has a high torque, although it is quite large in size. The disadvantage of the device is not too good productivity. In addition, such a device is quite heavy.

2. Vertical-axial. They have a large number of blades, which are located vertically to the surface of the earth, while they are parallel to the mast. Such devices are efficient and efficient, but they are quite expensive.

3. Helicoid rotor wind generator. Its feature is the shape of the blades: they are curved diagonally. Due to this, they rotate evenly. The downside of such an installation is its high cost, as well as strong noise. It is very difficult to construct the blades of a vertical wind generator of this type independently, as special equipment is required for this.

4. Many-lobed. They are quite effective in generating energy, but they are expensive. They have two rows of blades and impressive sizes.

The wind generator, the photo of which you can see in the article, is a fairly good energy producer, if you choose the correct design.

Can I make the device myself?

Naturally, many masters are interested in whether it is possible to build such a construction with their own hands. Of course you can. First you need to determine the type of product, as well as the tools that you will use, and the relevant materials.

It should be noted that a self-made vertical wind generator you can collect from what you have at hand. For example, an old gas cylinder or a metal barrel. And you have the opportunity to use old steel sheets or even fabric. It all depends on what kind of apparatus you want to build.

What materials are needed for work?

So, before making a windmill with your own hands, let's consider the question of what you will build it from. You will need these materials:

1. Plywood sheets (its thickness depends on the height of the structure, as well as on the number of blades and can be 0.5-1 cm). It is from this material that the part of the installation that will be rotated is most often performed.

2. Thin sheet steel, duralumin, flexible plastic (it is also possible to use fiberglass and fabric, but the latter option will be the least reliable).

3. A strong metal rod, the diameter of which must be at least 10 mm. Its height is about 60-70 cm. This rod will be the base of the turntable.

4. Fastening elements (nuts, bolts, rivets).

5. Wooden bars or metal corners for fixing the structure in an upright position.

In principle, this is the main list of materials necessary for work. Some other blanks may be needed during the execution of the action.

Required Tools

Before you make a windmill with your own hands, you should collect what you will work. You will definitely need these tools:

- An electric drill and drills to it.

- Scissors for metal.

- Electric jigsaw with canvas for wood and steel.

- Wrench or rivet.

- Shovel and other tools for excavation (if the construction will be fixed on the ground).

- Ruler, pencil, compasses.

In addition, a wind turbine is needed, but it is not difficult to find it. You can even do it yourself, but for this you will need to make some calculations.

Peculiarities of making blades

When the wind turbine is ready, you can start making it. To begin, we begin to produce a rotating part. Blades of the vertical wind generator are made of plywood. Before cutting them, try to draw a cardboard pattern. To do this, use a pencil, ruler and compasses. The blade length for the wind generator is 19 cm, and the width at the edge is 9 cm. It will be necessary to cut 6 pieces, which then will be connected in pairs. The shape of the blades is drop-like.

Use a jigsaw to cut the workpiece. The cut must be neat and even. To join the parts and form the wings will need wooden slats, a length of 53 cm.

Blades of the vertical generator should be at an angle. Usually it is 9 degrees to the center of the turntable. Naturally, this indicator can be adjusted after the design has been completely done. Next, the blades should be assembled and fastened to the connecting strips. In this case, self-tapping screws are used as fasteners. Drill a hole through the parts and the bar at the same time. If necessary, you can use glue. In addition, the bars should not extend beyond the edges of the parts. Try to maximize their alignment. This will determine the quality of the structure.

Further, the blades for the wind generator and all the wooden parts should be wrapped in metal. This is to ensure that the wood does not deteriorate under the influence of external conditions (rain, snow). You can use rivets or bolts to fasten the metal.

Now you can add a vertical-axial generator.

Features of manufacturing and assembly of the whole structure

We proceed to fix the wings on the central axis (steel rod). For this, circles cut from plywood are used. In order to properly draw them, use protractor. The diameter of these circles is 20 cm at a disc thickness of 1 cm. At their center, it is necessary to make a hole in which it will be possible to pass the rod.

Next, ready wings should be attached to the axis. For this, two nuts must be wound on both sides of the rod at a distance of 6 cm from the edges. Then on it are put on circles and also are fastened with a nut. The disks must be fixed tightly enough. As for the wings, they should be tightened not very freely, but must be able to rotate. Naturally, at this stage of the assembly you need to set the correct rotation angle of the blades.

In principle, the self-made vertical wind generator is almost ready. It is only necessary to make a frame-rack on which it will be fixed and free to rotate. To make it, you can take the metal corners of the required height. Naturally, you can apply and wooden beams. Please note that the wind force can be great, so you need to try to ensure maximum stability of the frame. Before connecting all the other appliances, the windmill needs to be checked and corrected.

Note that the rotor pitch can be dynamic or static. In the first case, the operating speed range is higher. However, it will have to be equipped with blades of a special shape. It is quite expensive and technologically difficult. With the static pitch of the rotor, you have only one specific speed. Faster wind turbine can not spin anymore. Although in this case the reliability of the device is higher, and the frequency of failures decreases.

In addition, when rotating the windmill, it is necessary to balance the structure. In this way, you can maintain its integrity. In addition, the wind can be very strong, and the speed should be reduced. For this, a special centrifugal regulator is used. It slows the blades if it exceeds the allowed rate. If the wind is weak, the efficiency of the unit can be increased by means of a chain mechanism.

A vertical wind generator, whose price is about 200-300 dollars and above, can be made independently. To generate electricity to the windmill, you can connect a conventional car device. A small generator is enough for you to provide light in the house, plug in chargers, power a laptop or other small appliances. In addition, you will also need a converter that will convert DC to AC. And still need a voltage regulator, which will make the mini-station work safe.

That's all the features of building a self-made plant for generating electricity due to wind movement. Good luck!
