Description

The invention relates to wind energy and can be used to generate electricity and, in particular, can be used as wind power plants. It is possible to use the invention in hydropower.

A wind turbine is known for converting wind energy into electrical energy, containing two sails that oscillate relative to each other and alternately change their resistance to the wind, while it is made in the form of vertical masts with sails installed at their upper ends and hinged on the base with lower ends, equipped with device for energy conversion, and the upper ends of the masts are able to swing relative to each other in antiphase (see patent RU No. 2131537 IPC F03D 9/00).

Significant disadvantages of this wind turbine design are the complexity of the design, low reliability, high cost, as well as the complexity of installing and replacing the wind turbine in case of malfunction.

Known wind generator containing a housing, while the housing is made mesh in the form of a weather vane, along the longitudinal axis of the front cylindrical part of which a flat magnet is horizontally located, at the front end of which a wind trap is installed, made in the form of a side surface of a hollow truncated cone, the rear side of the magnet rests on the disk , behind which a spring is installed, pressed against the rear side of the housing, a coil is placed on the inner side of the cylindrical housing, the magnet rests on supports with wheels at the end, which are included in the grooves attached to the inner surface of the cylindrical part of the housing (see patent RU No. 2612484 IPC F03D 5/ 06).

The main disadvantages of this wind generator design are large dimensions, design complexity, high cost, the need to constantly orient the wind generator towards the wind, depending on the amplitude of wind gusts, as well as the complexity of installing and replacing the wind generator in case of malfunction.

Known wind power generator, made with the possibility of installation on a platform and containing a rod, made with the ability to perform oscillatory movements under the influence of wind, a coil and a magnet, while the rod is made of one or more segments, and the coil or magnet is connected through a flexible element with the rod (see. patent RU No. 2710110 IPC F03D 5/06).

The disadvantages of this design of the wind power generator are the difficulty of installing and assembling wind power generators on the platform, the difficulty of replacing faulty wind power generators.

The task was to simplify the installation and assembly of wind power generators on the platform and to replace faulty wind power generators.

This problem is solved by the fact that in a wind power generator, made with the possibility of installation on a rigid or flexible platform and containing a housing, a rod made of a tension spring or a material with a higher modulus of elasticity in compression than in tension, with the ability to perform oscillatory movements under the influence of wind , a coil and a magnet connected through a flexible element to the rod, the rod is mounted on a platform made with inserted layers of conductive materials, using a thread or in the form of a self-tapping screw, a screw on the outer surface of the housing, and at the same time, slip rings are installed on the housing at the level , corresponding to the level of installation of layers of conductive materials on the platform.

Installing the rod on a platform made with inserted layers of conductive materials, using a thread or in the form of a self-tapping screw, a screw on the outer surface of the housing, and at the same time, installing slip rings on the housing at a level corresponding to the level of installation of layers of conductive materials on the platform, allows you to expand the possibility of installing a platform with wind power generators on various surfaces, to simplify the installation and assembly of wind power generators on the platform and the replacement of faulty wind power generators.

In FIG. 2 schematically shows a longitudinal section of a wind power generator in a bent state of the rod, under the action of wind, made of a material with a higher modulus of elasticity in compression than in tension;

In FIG. 4 schematically shows a longitudinal section of wind power generators in a bent state of the rods, under the action of wind, installed on a platform, with conductive materials embedded inside the platform;

In FIG. 5 schematically shows view A in FIG. 4 on the platform, with a plurality of wind power generators installed on it, in the straightened state of the rods, at the moment of absence of wind;

In FIG. 6 schematically shows a rack with wind generators 1 installed on it.

The wind generator 1 contains a magnet 2 located inside the sleeve 3 and coil 4, which are located inside the housing 5 and attached to a rigid or flexible platform 6. The magnet 2 is connected to the rod 7 through a flexible element 8. The rod 7 can be made of a tension spring or of a material with a greater modulus of elasticity in compression than in tension, for example, from polymeric materials, elastomers. When the rod 7 is made from a tension spring or from a material with a higher modulus of elasticity in compression than in tension, when the rod 7 is bent from the action of the wind, the length of the axial line of the rod 7 will increase compared to the length of the axial line of the rod 7 in a straightened state. The outer shape and configuration of the rod 7 may be different.

It is possible to manufacture housing 5 with a thread on the outer surface or in the form of a self-tapping screw, a screw (options not shown conventionally), to facilitate installation on platform 6.

The platform 6 is made with inserted layers of conductive materials 9. At the same time, slip rings 10 are installed on the housing 5 at a level corresponding to the level of installation of layers of conductive materials 9 on the platform 6. 1, if the housings 5 are made with a thread on the outer surface or in the form of a self-tapping screw, a screw (options are conventionally not shown).

It is possible to install wind power generators 1 on a rack 11, in the form of a tree, or on other surfaces, for example, on walls, roofs of buildings, houses and structures.

The most priority is the manufacture and use of wind power generators 1, with a total length of about a few millimeters to several centimeters.

The wind generator works as follows.

In calm weather, the rod 7 is in a vertical position. When the wind arises, the rod 7, under the influence of the wind, makes oscillatory movements, bending in different directions, depending on the direction of the wind. The rod 7, made of a tension spring or of a material with a higher modulus of elasticity in compression than in tension, will always tend to straighten up. In this case, the flexible element 8 will move the magnet 2 inside the sleeve 3 and the coil 4. The reciprocating movements of the magnet 2, inside the coil 4, will excite an electric current in the coil 4, from where the current will be transmitted through the slip rings 10 on the housing 5 into the inserted layers of conductive materials 9 on the platform 6, and further, for conversion and transfer to the consumer.

The possibility of carrying out the invention and at the same time providing a technical result, expressed in simplifying the installation and assembly of wind power generators on the platform and replacing faulty wind power generators, is confirmed by the drawings and description of the wind power generator.
