DESCRIPTION OF THE INVENTION
The invention relates to a low energy and can be used to create high-power installations.
Known wind power station comprising a wind wheel carousel, including a ring rails, vertical masts installed on them sailing working bodies associated with them castors in contact with the rail located under the awning, but also circular canopy and the tunnel, inside which the inductor and generators (see., AS USSR 1455037, MKI 5 F 03 D 5/04, 1989).
The disadvantages of such a facility is the availability of a support rail system, which greatly complicates and thus increases the cost of installation; Rolling large friction force on the rail, which lead to additional irreversible capacity loss; lack of energy storage inertial type.
Known and wind power plant, comprising vetrovosprinimayuschie working bodies placed on the ring pontoon and converter of mechanical energy into electrical energy, kinematically connected to the pontoon (see. The USSR AS 1719713, MKI 5 F 03 D 3/06, 1992).
Vetrovosprinimayuschie working prototype bodies located along the entire diameter of the bearing system and can shoot energy from across the pontoon area. However, they are ineffective because vetrovosprinimayuschie operating members located on the smaller radii are rotated at a linear speed which is less than the wind velocity. The smaller the radius, which is a working body, the greater must be the angular velocity of the support system.
Furthermore, the need for construction of the annular channel (or at least mounted more reference elements (stops) on the external perimeter of the pontoon) significantly increases the cost of installation and complicated installation. The disadvantage of the prototype is expressed in the increasing complexity of the transfer of mechanical energy to electrical generators.
The problem to be solved by the claimed solution, expressed in increasing the efficiency of the transformation of mechanical energy into electrical energy, without increasing the dimensions of the installation.
The technical result achieved in the solution of the problem is expressed in terms of optimization of the wind stream interaction with the elements of the device, and as a consequence of increasing efficiency.
The problem is solved in that the wind power installation comprising vetrovosprinimayuschie working elements placed on the ring pontoon, and a transducer of mechanical energy into electrical energy, kinematically coupled with the pontoon, characterized in that on the pontoon rotatable coaxially with, the supported carrier ring provided with complementary vetrovosprinimayuschimi bodies, wherein the ring pontoon and flexible rods are connected with the edges of the individual power converters hub mounted coaxially within the ring pontoon on a stationary base, and arranged along chords rod respectively and the carrier ring pontoon.
Furthermore, the pontoon comprises an annular rail, and the supported carrier ring on the rail. Thus vetrovosprinimayuschie working bodies are in the form of rotary blades.
Comparative analysis of the essential features of the claimed solution and the essential features of analogues and the prototype demonstrates its compliance with the criterion of "novelty".
Thus features characterizing part of the following claims solve functional problems.
Sign. ".. On the pontoon rotatably coaxially with the supported carrier ring provided with additional bodies vetrovosprinimayuschimi ..." to increase the number of working bodies, radially arranged bearing system, while allowing to increase the angular velocity of its rotation perceiving wind more efficiently .
The sign "... The individual power converters mounted coaxially within the ring pontoon on a stationary basis ..." allows to exclude a non-rotating elements of the bearing system zone where unwound water removal and to provide a simple energy converters of mechanical energy into electrical energy, increase security and alarm stability.
Signs ". .. A pontoon and ring of flexible rods are connected to the edges of the hubs of individual energy converters ...", "... and rods placed along the chords and respectively pontoon bearing rings ..." allows to center pontoon and bearing ring relative to the stationary base and to transfer torque. In addition, the availability of flexible rods facilitates the work of devices with waves and water level fluctuations.
Symptom ". .. Vetrovosprinimayuschie working bodies in the form of rotary blades ..." allows you to increase the efficiency of energy extraction.
Signs of the third paragraph of claims concretise the constructive execution of load-bearing structures and their interactions.
Brief Description of the drawing, which shows a wind power installation in the section.
The drawing shows one pontoon bearing ring 2, the blade 3 and 6, the rotation mechanism 4, and 7 of these blades, the ring rail 5, the stationary base 8, power converters 9 and 10, hub 11, flexible rod 12.
The plant consists of two bearing systems, one nested in the other and rotating at different angular speeds. A support system is designed as an annular pontoon 1, one side of which is made necessary forms of support to the water surface. On the free side of the pontoon 1 set vetrovosprinimayuschie working bodies, made in the form of rotary blades 3 with the mechanism of rotation 4. On the pontoon 1 set ring rail 5. At the roundabout rail simply supported carrier ring 2 (the second carrier system) that has the rotary blades 6 with 7. its rotation mechanism rotating mechanisms 4 and 7 of the blades 3 and 6 can be made in any commonly known format (for example, the gear train from the drive motor controlled by a weather vane). Inside the pontoon 1 to stationary base 8 is coaxially mounted power converters 9 and 10, at the upper ends of which are made flexible hub 11. Rod 12 (for example, a system of ropes) respectively arranged along the chords of the pontoon 1 and the carrier ring 2, hub 11 edge connect power converter 9 a pontoon 1 and the hub edge 11 of the energy converter 10 with a bearing ring 2.
The device operates as follows. When the wind vane 3, and 6 are set to the operating position by means of their rotation mechanisms 4 and 7. The three blades untwist pontoon 1 and the blade 6 - a carrier ring 2. Due to the friction forces of the energy of the water at the initial time spent on the "unwinding" water. Formed a water ring around the stationary base 8. The rotational energy carrier systems 1 and 2 by means of flexible rods 12 through the hub 11 is transmitted to the power converters 9 and 10, nahodyaschiesya on the stationary base 8.
This solution allows the use of wind energy in the most fully covered by the scale. It is possible to get different rotational speed and bearing systems used for removal of a quality management or energy.
