A wind installation with a horizontal axis is also known, which includes a main axis fixed on a plate by means of fixing mechanisms with sliding bearings, a circular plate on which three support arms are fixed, which support the radially arranged blades, a mechanism of control that serves to remove the rotor from under the action of the wind and adjust the angle of attack of the blades [2].

Dezavantajele soluţiilor tehnice date constau în construcţia complicată, numărul mare de elemente şi principiul complicat de scoatere a instalaţiilor de sub acţiunea vântului, ceea ce reduce considerabil fiabilitatea, randamentul mecanic şi eficienţa economică. The disadvantages of the given technical solutions consist in the complicated construction, the large number of elements and the complicated principle of removing the installations from under the action of the wind, which considerably reduces reliability, mechanical efficiency and economic efficiency.

Problema pe care o rezolvă invenţia constă în controlul puterii turbinei şi limitarea suprasolicitărilor asupra palelor rotorului prin utilizarea unui principiu simplificat de scoatere a rotorului de sub acţiunea vântului. The problem that the invention solves consists in controlling the power of the turbine and limiting overloads on the rotor blades by using a simplified principle of removing the rotor from under the action of the wind.

Rezultatul tehnic al invenţiei constă în asigurarea unei fiabilităţi majorate, construcţia simplă şi principiul simplificat de scoatere a rotorului de sub acţiunea vântului. The technical result of the invention consists in ensuring increased reliability, simple construction and the simplified principle of removing the rotor from the action of the wind.

Invenţia se explică prin desenele din fig. 1 şi 2, care reprezintă: The invention is explained by the drawings in fig. 1 and 2, which represent:

- fig. 1, vederea generală a instalaţiei eoliene cu ax orizontal, în poziţie de lucru; - fig. 1, general view of the wind turbine with horizontal axis, in working position;

- fig. 2, vederea generală a instalaţiei eoliene cu ax orizontal, în poziţie de scoatere a palelor rotorului de sub acţiunea vântului. - fig. 2, the general view of the wind turbine with a horizontal axis, in the position of removing the rotor blades from under the action of the wind.

Instalaţia eoliană cu ax orizontal (vezi fig.1) include arborele rotorului 1, pe care sunt fixate palele 2 cu profil aerodinamic asimetric, un generator electric 3 cu magneţi permanenţi, arborele căruia este unit prin cuplajul 4 cu arborele rotorului 1, puntea de bază a gondolei 5, pe care sunt instalate suporturi 6, dotate cu lagăre 7, care asigură sprijinul arborelui rotorului 1. Puntea de bază a gondolei 5 este fixată prin intermediul articulaţiei 9 pe arborele vertical 8. Pentru asigurarea echilibrului gondolei 5, centrul de greutate al gondolei 5, pe care sunt amplasate rotorul 1 cu palele 2 şi generatorul electric 3, este deplasat la distanţa e de la axul articulaţiei 9. Arborele vertical 8 este amplasat cu posibilitatea rotirii în lagărele 11, instalate în turnul 12, fixat pe fundaţia 13. De asemenea, pe turnul 12 este fixat suportul 10 al gondolei 5. The wind installation with a horizontal axis (see fig.1) includes the rotor shaft 1, on which the blades 2 with asymmetric aerodynamic profile are fixed, an electric generator 3 with permanent magnets, the shaft of which is joined by the coupling 4 to the rotor shaft 1, the base bridge of the nacelle 5, on which are installed supports 6, equipped with bearings 7, which ensure the support of the rotor shaft 1. The base deck of the nacelle 5 is fixed by means of the joint 9 on the vertical shaft 8. To ensure the balance of the nacelle 5, the center of gravity of nacelle 5, on which the rotor 1 with the blades 2 and the electric generator 3 are located, is moved at a distance e from the joint axis 9. The vertical shaft 8 is placed with the possibility of rotation in the bearings 11, installed in the tower 12, fixed on the foundation 13. Also, the support 10 of the gondola 5 is fixed on the tower 12.

Instalaţia eoliană cu ax orizontal funcţionează în modul următor. The wind turbine with horizontal axis works in the following way.

Curenţii de aer 14 acţionează asupra palelor 2, antrenând rotorul 1 în mişcare de rotaţie. Mişcarea de rotaţie a rotorului 1 este transmisă rotorului generatorului electric 3 prin intermediul cuplajului 4. La schimbarea direcţiei de acţiune a curenţilor de aer se realizează automat mişcarea de rotaţie a arborelui vertical 8 împreună cu gondola 5, reintrând în zona acţiunii vântului. Scoaterea palelor 2 rotorului 1 de sub acţiunea vântului din poziţia I de lucru (vezi fig. 1) în poziţia II (vezi fig. 2), în cazul intensificării forţei curenţilor de aer se realizează prin intermediul articulaţiei 9, care oferă posibilitatea deplasării unghiulare a gondolei 5 în jurul axei OO. Acţiunea vântului cu viteza de până la 15 m/s oferă randament şi eficienţă de conversie maximă. La depăşirea acestei viteze, pentru evitarea avarierii instalaţiei, are loc deplasarea unghiulară treptată a rotorului 1 în jurul axei OO, cu un unghi α. Astfel, pentru viteza vântului de 17,5 m/s unghiul respectiv este α1, 20 m/s - α2, 25 m/s - α3, unde α1 < α2 < α3. Suportul 10 asigură echilibrul gondolei 5 în caz de intervenţie a unor factori externi neprevăzuţi. The air currents 14 act on the blades 2, driving the rotor 1 in rotation. The rotation movement of the rotor 1 is transmitted to the rotor of the electric generator 3 by means of the coupling 4. When the direction of action of the air currents changes, the rotation movement of the vertical shaft 8 together with the nacelle 5 is automatically performed, re-entering the area of the wind action. The removal of the blades 2 of the rotor 1 under the action of the wind from working position I (see fig. 1) to position II (see fig. 2), in case of intensification of the force of the air currents, is carried out by means of the joint 9, which offers the possibility of angular movement of nacelle 5 around the axis OO. The action of the wind with a speed of up to 15 m/s offers maximum efficiency and conversion efficiency. When this speed is exceeded, in order to avoid damage to the installation, the rotor 1 gradually moves angularly around the axis OO, with an angle α. Thus, for the wind speed of 17.5 m/s the respective angle is α1, 20 m/s - α2, 25 m/s - α3, where α1 < α2 < α3. The support 10 ensures the balance of the gondola 5 in case of the intervention of some unforeseen external factors.
