Description

WIND TURBINE

(options)

The invention relates to the electric power industry, namely wind power plants and wind turbines. And it can be used in the assimilation of wind power in various industries.

Closest to the technical nature of the claimed is PATENT N22581986, published June 27. 2015 bul. N ° 18, author Noroyan G.

The disadvantage of this turbine is its small working area and the problem of the negative impact of wind on the turbine, from the side that rotates against the wind, has not been completely solved.

Technically, the problem is solved by installing blades on the turbine so that when rotating against the wind, the blades do not resist. The blades are mounted so that they rotate around their axis up to 180 ° in the direction of travel against the wind.

The turbine consists of a shaft, which is equipped with at least one disk, on which the blades are uniformly mounted around the entire perimeter. There can be two or more disks on a shaft, depending on the turbine features.

The blades consist of a flat sheet and are mounted on an axis. The axis is pivotally mounted, or the blade plates are pivotally mounted on the axis, the number of blades is different, it is selected individually.

The axis is installed between two disks (on one, if there is only one disk) parallel to the shaft. The turbine can be multi-tiered, an additional disk is installed for each tier.

The blades can be $ -shaped, straight or of another known type, or bent along the extremity from the axis differently so that the blades on one side more resist the wind, and so that when the turbine rotates, the wind presses on the bent side and scrolls the blades around its axis up to 180 °. The axis is in the middle of the plane of the blade, or offset from the middle, depending on the particular case.

The blades can be of two planes (main and additional), interconnected pivotally. The additional part when the blades move to the working side under wind pressure opens up to 180 ° in order to add the area of resistance on their side of the blade. After a U-turn the additional part almost does not contribute to the movement and coalesces, so that the blades do not turn back before the transition of the blade to the movement against the wind. If L1 is the short side of the blade from the axis; L 2 is the long side of the blade from the axis; L3 are additional frequent blades, then L1 ⁺ L3 is greater than L2, and L1 is less than L2.

The working side of the turbine - meaning along the way to the wind.

The blades can be provided with air fairings, for more efficient operation of the turbines, and to avoid air congestion.

Fairings of different types of any geometric shape (rectangle, circle, triangle), and the location on the blades in different ways, and are provided with appropriate valves. The valves are made of flat material and are mounted on the axis so that when moving against the wind, they are pressed against the blades and do not interfere with the movement, and are opened on the working side of the turbines, rotating on the axis up to 90 °, to use the force of the exhaust air. Fairing valves can open at different angles and are provided with stops to adjust the opening angle. The limiters are of different known types and are adapted differently. The radome os can be located both on the vertical and horizontal plane of the blade.

A limiter is installed on the disk for each blade so that the blades abut against it at the desired location of the blade. Limiters can be located on the blade, so that the blade with the limiters rests against the disk before turning, to change the angle between the blade and the direction of the wind. After a turn, the blade rests against the disk with a stop, so that the blade resists the wind when the turbine rotates, in the direction of the wind. The limiter is installed so that, when the turbine rotates against the wind, it does not prevent the blades from freely spinning around its axis, and remain parallel to the wind along the plane. Limiter of various known types.

The limiter can be located anywhere on the turbine, but so that when the blades are turned, they gently pressed against the limiter. Limiters are equipped with dampers. The damper is of various known types (spring, rubber, ... or other known device.) And is installed in different ways. The pacifier can be in the form of a pipe, half pipe, square, etc. The dampers can be in the form of a blade and rotate around its axis so that on the working side the turbines turned around with the area facing the wind, and when facing upwind, they turned with an edge towards the wind.

Rollers can be mounted on the damper or limiter to reduce friction between parts when they are touched. The rollers are mounted so that the blades reach the damper, and together they move to a soft stop.

The turbine can work both vertically and horizontally, and at a favorite angle.

To facilitate the design, the disk is reduced in size and the veins are mechanically installed on the disk veins on the same plane with the disk, for each blade separately. Axles, blades and dampers can be installed on the veins.

With a horizontal arrangement of the turbine, the shaft is mounted on two bearings at the edges, or in different places intermediate, additional bearings can be installed.

The shaft can be mounted on one support and blades are mounted on both sides of the shaft.

To obtain electricity, with a low wind force, a stand under the Auxiliary Device (WU) is mechanically mounted on the turbine stand, so as to ensure that the WU disk engages with the edges of the turbine disk to maintain its rotation speed at a lower wind speed.

The mechanical control unit is mounted on a stand and provided with an electric motor; a rubber disk is installed on the shaft of the unit. WU is designed so that the speed of rotation of the disk is much greater than the speed of rotation of the turbine. The WU engine can be low-power, but high-speed, to achieve higher efficiency.

The VU disk can be in the form of an ellipse, round or other known type, and the movement is transmitted both continuously and by different pulses in different places of the turbine. The number and power of the WU for each turbine is different.

The transfer of motion from the WU to the turbine can be carried out by various known methods.

WU is installed to ensure continuous operation in cases where the cost is less than the return. WU is effectively installed at any wind power. When installing a WU with a pulse transmission of motion, it is possible to achieve an increase in the rotation speed so that the blade limb vector

s approached the wind speed. It can even exceed wind speeds, and efficiency will approach the maximum possible.

If the turbine disk is provided with streaks, then the coupling with the WU disk can occur with the streaks in pulses. The longer the WU is installed from the shaft, the more efficient the WU operation is in the pulse mode of motion transmission.

The design consists of at least one disk 7 on which the blades 3 are mounted uniformly throughout the parameter. Each blade is provided with a limiter 1. The blades 3 consist of a flat plate with the ability to rotate around its axis 2. The extremities of the plates from the axis are bent in different directions, so that the wind exerts more pressure on the bent 21 side than on the back side 22, to ensure rotation of the blade around its axis. The blades can be in the form of an Arab unit (1) and set so that the small tail 17 is opened under wind pressure up to 180 ° and is folded up to 30 °, the tail 17 + main part 16 on the blade 3 is pivotally mounted. The limiters of the blade 3 can be in the form of the above said blade, and mounted on the disk 7, between the blade and the shaft 4, on the same line or offset in different ways. The limiter 1 is installed on the disk 7, so that when turning the blades collide with the limiter1. The stops 1 are provided with rollers (not shown) at the contact points of the blades (not shown) so that the blade and the damper are not rubbed against each other, but rolled along the plane of the blade and exclude friction of the blade with the limiter. By delivery, a turbine 8 is installed mechanically, with a motor 11, and a disk 10. The cylinder is installed so as to ensure the adhesion of the disk 0 and the disk 7 of the turbine, to maintain the speed of rotation of the turbine at a lower wind speed. Disk 10 WU can be in the form of an ellipse, round or other known shape, and WU can be installed in different places for continuous or pulsed transmission of movement to any part of the turbine (disk, shaft, axis, blade ...), by various known methods.

The disk 10 WU may be made of rubberized material.

The design works as follows: under wind pressure, on one side of the turbine, the blades unfold with an area along the wind path. The blades of the other side abut against the limiters and resist the wind, and the turbine rotates in the resisting direction. When the blade moves to the working side, the limiter pushes the blade from the back side. The blades of the pressure limiter change the angle to the ratio of the movement of the wind, and under the pressure of the wind it rotates around its axis to 180 °.

When the turbine is horizontal: under the pressure of the wind, the upper blades resist the wind leaning on the limiter and the lower blades become an edge to the wind, before the upper blades move against the wind, they resist, when they turn, turn the edge to the wind

At the sight of the blade of the Arabian unit, under the pressure of the wind the PM blade opens and rests on its limiter, the area of resistance in the side of the PM increases, the blade rotates around its axis to 180 °, and rests on the blade limiter, on the other side of the blade. After a turn under wind pressure, the DC 17 covers itself so that the blade 3 does not turn back. Under the pressure of the wind, the blade rotates along the wind half a turn. Going to in the direction of movement against the wind, the blade rotates around its axis 2 and remains an edge to the wind, before passing along the wind.

In the variant where the plates are bent in different directions, the figure N ° 1 is shown, on the side 21 the wind glides along the final part, and the side 22 fully resists, thereby ensuring the blade to turn and stability when working along the path to the wind. Turning sideways against the wind, the blade rotates around its axis2 in the direction of travel and always remains an edge to the wind.

In the case when the support for the blade is the shaft 4, and one side of the blade is longer and reaches the shaft, when the blade rotates along the wind, the long side rests on the shaft, and becomes a plane to the wind, under the pressure of the wind, the turbine rotates. When the blade moves against the wind, the wind presses on the long side of the blade and rotates around its axis up to 180 °, the blade becomes an edge to the wind before the transition in passing to the wind. When passing along the wind, the blades with the long side of honey agarics rest on the shaft and resist the wind until they move against the wind.

When the wind is small, the WUs automatically turn on, the movement is transmitted to the turbine in various ways (gearbox, gearbox, pulley, ...) and the turbine maintains a minimum speed, and the energy received by El is more than the energy consumed, and the electricity received from the wind is added to the chip. In the case of impulse transmission of motion, the ellipse disks of the VU rotate at a high speed and clings to the turbine disk at the edges, while instantly touching the disk, the rubber part of the disk transmits the force of movement in the form of an impact with high speed. If there are several WUs on the turbine, then they can transmit the movement in turn, or at the same time, for each turbine it is calculated individually, and so as to obtain more than the flow rate. WU can transmit motion both impulsively and continuously.

If there are fairings, the fairing valves in the direction of the wind open slightly and rest against their limiters, the wind passing through the fairing tangentially presses on the valves and moves to the side, transmitting the turbine movement and the problem of air congestion is solved, and the pressure in front of the forward blades is added.

The movement of the generator is transmitted in various known ways, as the generator can be built-in.
