Description

The utility model relates to engine building, in particular to the construction of wind engines, and can be used to generate electricity by converting the energy of the air flow.

A known wind generator containing a wind wheel and a magnetoelectric generator, the rotor of which has permanent magnets and is connected with the wind wheel, and the stator is made of a charged magnetic core with windings (patent RU 2168062 C1, IPC F03D 9/00, published on 05.27.2001, author Ivashintsov D.A. . and other wind generator).

The disadvantages of this design are low efficiency, high rotational speed of the rotor and relatively high revolutions at which the generator provides electric energy to the network.

Known rotary wind power plant containing a rotor made in the form of a disk with blades mounted on it, made in the form of aerodynamic wings and located with a gap relative to the rotor shaft, mechanically connected with the shaft of the electric generator, a cowl mounted on the shaft in front of the rotor downstream, covering the gap between the internal the edges of the blades and the confuser, placed in front of the rotor downstream (patent RU No. 2425249, IPC F03D 1/04, published on 08.20.2002, author Ivaneyansky A.V. et al. Rotor wind farm).

The disadvantage of a wind power plant is its low efficiency and it requires a stable wind flow speed for operation, as well as a high moment of rotation of the rotor, only at high speeds does the charge current of the batteries begin to flow.

This technical solution is selected as a prototype.

The technical result of a rotary wind farm is to increase efficiency by reducing friction in the mechanical components of the generator.

The technical result is achieved by the fact that the wind power shaft is made of upper and lower parts, a wind wheel is installed on the upper part of the shaft, consisting of blades rigidly fixed to the shaft, made of rectilinear and arcuate parts, pivotally connected, the lower part of the shaft rests on a magnetic support node, which made in the form of a hollow cylinder, inside of which are placed two permanent magnets that are facing the same poles to each other, and on the lower part of the shaft there is an electric generator whose rotor The horn is made in the form of a flywheel, on which permanent magnets are mounted, the upper part of the shaft and the lower part of the shaft of the wind power station interacting through the trip clutch. An increase in the efficiency of a wind power plant is achieved due to the folding blades of the wind wheel, the installation of a trip clutch, the rotors of the electric generator are made in the form of flywheels, and the reduction of friction in the mechanical assembly is achieved through the use of a magnetic assembly.

Fig 4. The design of the magnetic node.

The rotor wind farm contains a wind wheel 1, consisting of the straight part of the blade 2 and the arcuate 3, interconnected through a loop 4, the wind wheel blades have a rigid connection 5 with the upper part of the shaft 6, below the blades of the wind wheel there is a trip clutch 7, the body of the trip clutch 7, the upper disk clutch 8, the lower clutch disk 9, the generator 10, the lower part of the shaft 11, the magnetic support assembly 12, the upper permanent magnet 13, the stopper for the arcuate blade 14, the spring in the trip clutch 15, the lower permanent magnet of the support node 16.

Rotary wind farm operates as follows.

In the presence of a wind of 1-15 m / s, the wind flow pushes the wind wheel 1 of the rotor power plant, “opening” the working blade 2 and 3 due to the hinge-fastening 4, the remaining non-working blades at the moment, being in the “closed” state, help to reduce the braking wind flow effect. With a hurricane wind of more than 15 m / s, the blades 3 will not have time to open, which excludes mechanical damage to the wind farm. The blades 2, due to the rigid connection 5 with the upper part of the shaft 6, cause the shaft to rotate around its axis together with the upper disk 8 of the trip clutch 7, since it is also rigidly connected to the upper part of the shaft 6. The upper disk, due to the presence of a pushing arm, beveled steps, transmits the rotation force from the upper part of the rotor wind turbine to the lower 9, thereby bringing the rotary flywheels into motion around its axis. The generator 10 began to generate electricity.

In the absence of a stable wind flow, but in the presence of short-term gusts of wind, the blade 3, before starting its work, is "opened" due to the hinge-loop fastening 4, the stopper for opening the blade 14 restricts the movement of the blade 3, transfers rotational energy to the rotor flywheels of the electric generator 10, they began to rotate, the wind flow dried up, the blades stop due to the release clutch 7, where the lower disk 9 is constantly pressed against the upper disk 8 by a spring 15 for constant interaction. If the rotational speed of the lower disk 9 in the trip clutch 7 is higher than the rotational speed of the blades, then due to the beveled step, the rotational force is not transmitted to the upper part of the shaft 6. The rotor flywheels, having accumulated kinetic energy in themselves, continue to rotate only with the lower part of the shaft 11, since the lower disk 9 of the trip clutch 7 does not have a mechanical connection with the upper disk 8 of the trip clutch 7. Due to the magnetic support unit 12, in which the upper permanent magnet 13 interacts with the lower permanent magnet 16 in the lower part of the shaft 11, the internal resistance of the wind farm as a whole is reduced.
