The wind-wheels are connected in series to one or several vertical bunches, with two or more wind-wheels in each bunch; support bearings in the upper part of the tower to which each bunch is attached; one or more electro-generators, those are placed on the earth, with connected to those through respective input appliances, for instance, muffs, of reducers, the lower ends of the bunches; those can, thus, rotate in a free way.

Description

Description of the invention

The invention is related to wind energy, namely to the construction and placement of wind turbines. 2 There are two main types of windmills that convert wind energy into mechanical rotational energy.

Helical windmills, the axis of rotation of which must be parallel to the direction of air movement (horizontal axis) and orthogonal windmills (or rotors), the axis of rotation of which is perpendicular to the movement of air (vertical axis).

Both the first and the second have their advantages and disadvantages. Helical windmills (propellers) require 70 special devices to follow the direction of the wind and turn the propellers and generators in space.

Vertical-type rotors work regardless of wind direction, but there is the problem of raising them to greater heights to take advantage of the altitudinal gradient in wind speeds.

Propeller windmills, when they rise to greater heights, need strong capital towers that can withstand the load of hurricane (gale) winds and hold heavy generators. 12 Lifting of rotors of the vertical type, as far as we know, is not used.

They are installed on the ground and each rotates its electric generator located in its lower part.

The first and second type of windmills, when used on a large scale, require large land areas to prevent wind shading and the influence of windmills on each other.

Another contradiction is the impossibility of creating super-powerful wind engines, which forces to produce 20 electricity with a large number of small generators. This reduces the efficiency of energy production and increases its cost.

The proposed invention is an attempt to overcome these contradictions - a garland wind power plant. Its essence is that electric generators and high-power reducers are located on the ground near one or several high towers, and windmills, assembled in garlands, descend from above and connect to 22 electric generators with the lower ends of the garlands. "

At the top, each garland is connected to the top of the tower via a support bearing that supports it and allows it to rotate freely.

At the same time, several garlands can be connected to one gearbox from below and rotate one high-power generator, for example, through overrunning clutches. -- 30 Types of rotors included in one garland can be different. These can be Darier rotors, Yu rotors

Savonius, sailing wind engines (type ASSR 1760598) and even screw (propeller) windmills, which are located on the garland and have devices for transmitting rotation to the entire garland and orienting the propellers in the W direction of the wind. co

The rotors are connected to each other in the garland either through gimbals or directly through couplings, which are supported by several consoles extending from the tower. at

It is possible to use generators whose axis is vertical and is a continuation of the axis of rotation of the garland and which are connected to each garland directly.

The variants of the garland wind power plant are shown in the drawing. A garland wind farm with two garlands and one tower is shown. One tower may have Z and 4 garlands or Z 50 more (see Fig. 1). Figure 2 shows the same wind farm, but one garland has a vertical arrangement and is supported by consoles. The second garland (on the right) is connected directly to a large electric generator, as in Fig. 1.

Figure 3 shows the operation of three garlands on one generator. 45 Fig. 4 shows the possibility of creating a wind wall, when several garlands on both sides of the U-shaped tower fill the entire space, simultaneously acting as tension ropes that hold the entire structure during gale force winds.

The drawings show: shk 1 - windmills of various types; cl 20 2 - support bearings;

C - cardan joints; t 4 - support tower; - reducer; 6 - electric generator; 7 - electric generator with a vertical axis. in. The operation of the garland wind power plant is obvious from the presented drawings.

Thus, on the left in Fig. 1, a garland of orthogonal rotors (1) is shown, which are held from above by support bearings (2), and from below enter the reducer (5), which transmits rotation to the large generator (6).

Above are Darier rotors, below are two sailing wind engines. Sailing wind engines have a large 60 torque and a defined direction of rotation. Darier rotors require spin-up (start-up) and when the wind reaches a certain speed, they work stably with high energy conversion efficiency.

When the speed of rotation of the garland increases, the blades of the sailing wind turbines can open and not slow down the work of the entire garland.

Thus, at low and medium winds, sailing wind engines will mostly work, and at high wind speeds - Darier rotors. The speed of rotation of the entire garland will be averaged due to the inertia of the total mass and the loading of the generators.

According to measurements at different heights from 50m to 120m, the wind speed varies by 20-2595. This is a small difference and there will be no problems in the operation of the Darier rotor at a height of 12Ω and 5Ω.

Depending on the type of electric generators (6, 7), they can be connected to the garland through a reducer (5) or directly, when the axis of the generator is a continuation of the axis of the garland as shown in (see fig. 1, 2) on the right.

One of the advantages of the proposed garland wind power plant is the ability to capture large parts of space and use the altitudinal gradient of wind speed distribution, while occupying small land areas. 70 Taking into account the possibility of twisting of the garlands under the influence of strong wind, all rotors are connected to each other through cardan joints (3).

Fig. 2 on the left shows a garland that does not require gimbal joints because it is supported by consoles (8), which depart from the tower (4) and support the garland with support bearings.

The proposed garland wind power plant makes it possible to use wind energy in those places where 7/5 Known wind turbines are not efficient because they require large land areas.

Energy production by large power generators is more efficient, capital costs and costs for installation work are reduced, the stability of electricity production increases, and the competitiveness of wind energy increases.

The presence of several garlands on one wind turbine increases its maintainability and reduces operating costs.

Any string can be easily shut down for repairs or maintenance while the others continue to generate electricity continuously. The selection of sites for the construction of wind turbines is facilitated, taking into account the fact that wind turbines are located at a considerable height and require much smaller land areas than with their traditional use.

Capital costs for the construction of wind turbines of similar capacity will be significantly reduced, because, firstly, tall towers do not have to support heavy electric generators, and secondly, the garlands themselves play the role of tension cables, which increases the strength of the entire system in relation to gusty winds and, accordingly, reduces « requirements for the strength of the towers themselves.

In addition, the installation work of lifting light garlands and connecting them to the support bearings is much easier than climbing to the tops of the towers of large electric generators and installing the blades of giant propellers. "- zo Installation of the garland can be done from the ground Through a simple block that pulls the upper part of the garland with a cable to connect it to the bearing. After that, the connection of the lower part of the garland to the generator takes place on the ground. The lower part of the garland can have tensioning and shock-absorbing (spring) elements, which make it easy to finish the work on its installation and inclusion in the work. co
