Definitions
- the utility model relates to devices that use renewable energy sources based on wind and can be used as an autonomous power plant to meet their own electricity needs of individual consumers, as well as an additional source of energy in the overall energy system.
- a wind generator is understood as a device for converting the kinetic energy of the wind flow into the mechanical energy of the rotation of the rotor of an electric machine with its subsequent conversion into electrical energy.
- a wind turbine with rotation around a vertical axis containing a rotor capable of rotating under the action of the wind around its vertical axis with respect to the horizon, and a rotary shaft associated with the rotor (RU 2294452 Cl, F03D 3/00, publ. 27.02.2007 Bull. b).
- the specified wind turbine is rigidly mounted on several supports, is bulky and prone to destruction in conditions of hurricane gusts of wind, sharply changing weather conditions.
- a rotary wind turbine containing a frame with a shaft fixed on it with the help of bearings and working blades, which are connected to the shaft with the possibility of rotation with it and are made in the form of plates bent in a vertical plane in a spiral, and in a horizontal plane along an arc of plates (RU 2210000 C1, F03D 3/00, published 10.08.2003 Bulletin N°22).
- the disadvantage of this design is that in a cold climate and a sharp temperature drop, in the presence of an icy wind, ice accumulates on the working blades, their imbalance and destruction.
- a power plant for the use of wind energy containing a vertical shaft located on the foundation with an electric generator consisting of a stator and a rotor, and rocker arms on which the blades are installed, while a fixed axis is additionally installed on the foundation, made in the form of a cylindrical pipe, a vertical shaft made in the form of a cylindrical pipe enclosing a fixed axis and located coaxially with it (RU 2347942 Cl, F03D 3/00, publ. 27.02.2009 Bull. b).
- this power plant has low reliability and safety, it has a short service life.
- the specified power plant in its technical essence and purpose is the closest to the claimed utility model and is taken as a prototype.
- the utility model was given the task of providing an increase in reliability and safety, increasing the life of a power plant for the use of wind energy in conditions of strong gusts of wind and hurricane winds.
- the general essential features of the technical solution used in the prototype and in the claimed technical solution are characterized by the presence of a fixed axis in the form of a cylindrical pipe, an electric generator, a vertical shaft made in the form of a cylindrical pipe enclosing the fixed axis and located coaxially with it, with blades fixed on it .
- the technical result of the utility model is to increase the reliability and safety, increase the service life.
- the technical result is achieved due to the fact that in a power plant for the use of wind energy, containing a fixed axis in the form of a cylindrical pipe, an electric generator, a vertical shaft made in the form of a cylindrical pipe enclosing the fixed axis and located coaxially with it, with blades fixed on it , the vertical shaft is fixed on the fixed axis by means of two bearing assemblies, the upper one contains an angular contact bearing, and the lower one contains a self-aligning bearing.
- Angular contact (radial-axial) bearings can simultaneously perceive both radial and axial (axial) forces.
- angular contact bearings are designed for the prevailing radial loads inherent in the actual operating conditions of the wind turbine.
- a self-aligning ball bearing has two rows of balls with two independent raceways on one inner ring and one common spherical raceway on the outer ring. This design feature provides self-alignment of the bearing, allowing it to perceive angular misalignments and bends of the vertical shaft relative to the fixed axis in strong gusts of wind and hurricane winds.
- Self-aligning bearings are especially needed in units where significant shaft bends or various misalignments are possible. In addition, they have the lowest coefficient of friction of all rolling bearings, which makes them less susceptible to heat even when rotating at high speeds.
- the low coefficient of friction of the self-aligning ball bearing increases not only its reliability and safety, increases the service life, but also the entire wind turbine as a whole.
- self-aligning bearings are able to compensate for such misalignments of the shaft, in which other bearings wear out quickly.
- Self-aligning double row ball bearings thus self-align during operation, compensating for angular misalignment of the vertical shaft with the fixed axis, which occurs when bending and misaligning in.
- the drawing shows a wind turbine (side view).
- the vertical shaft 3 is made in the form of a cylindrical tube, covering the fixed axis 2, and is located coaxially with it. Blades 4 are rigidly attached to the shaft 3.
- the vertical shaft 3 is articulated with the rotor 5 of the generator, which is located coaxially with the rigidly fixed stator 6.
- the vertical shaft 3 is articulated with the fixed axis 2 by means of bearing assemblies, the upper of which contains an angular contact bearing 7, and the lower contains a self-healing bearing 8.
- the wind generator operates as follows.
- the wind load on the blades 5 rotates the vertical shaft 3 with the rotor 5 of the electric generator.
- the rotor 5 rotates relative to the fixed stator 6, the mechanical energy of the rotational movement is converted into electrical energy.
- the prepared prototypes of the wind generator confirmed the achievement of the claimed technical result. During operation, without failure, they withstood the effects of strong gusts of wind and hurricane winds.
- the claimed design of the wind generator is new, industrially applicable. It is easy to install and easy to maintain.
- the proposed technical solution is especially relevant in the context of global climate change, a sharp increase in the number of natural disasters, including hurricane winds, tornadoes, snowy and harsh winters.
