Abstract
Изобретение позвол ет повысить выработку электроэнергии путем расширени диапазона рабочих скоростей ветра при наибольшем коэффициенте использовани его энергии. С увеличением скорости ветра мощность электрогенераторов 11 двух ветроагрегатов установки поддерживаетс посто нной изменением сначала диаметра ветроколеса первого ветроагрегата вплоть до своего минимального диаметра, равного максимальному диаметру ветроколеса второго ветроагрегата, а затем уменьшением диаметра ветроколеса второго ветроагрегата. Изменение диаметров осуществл етс механизмами, каждый из которых имеет приводной двигатель 12, кинематически св занный с ним валик 13, расположенный коаксиально в полости вала 3, размещенного на поворотном основании 2, коническое зубчатое колесо 14, размещенное ва втулке 5 ветроколеса, ходовые винты, установленные коаксиально внутри махов 6 с коническими шестерн ми 16, контактирующими с колесом 14, и гайки, взаимодействующие с винтами и закрепленные на лопаст х. При изменении диаметра лопасти перемещаютс вдоль махов, а последние поворачиваютс , сохран оптимальный угол установки лопастей, соответствующий максимальному КПД установки. Поворот махов осуществл етс устройством, содержащим расположенный во втулке 5 соосно с валом 3 приводит с коническим зубчатым колесом и контактирующие с последним конические шестерни, закрепленные на махах 6. Стабилизатор частоты тока электрогенератора поддерживает ее посто нной при любых значени х диаметров ветроколес, работающих с максимальным коэффициентом использовани энергии ветра. 1 з.п. ф-лы, 3 ил.The invention makes it possible to increase the production of electricity by expanding the range of operating wind speeds with the highest utilization of its energy. With an increase in wind speed, the power of electric generators 11 of two wind-driven units of the installation is kept constant by first changing the wind wheel diameter of the first wind turbine up to its minimum diameter equal to the maximum wind wheel diameter of the second wind turbine, and then decreasing the wind wheel diameter of the second wind turbine. The diameters are changed by mechanisms, each of which has a drive motor 12, a roller 13 kinematically associated with it, located coaxially in the cavity of the shaft 3 placed on the rotary base 2, a bevel gear 14 placed on the windwheel hub 5, running screws mounted coaxially inside the swings 6 with bevel gears 16 in contact with the wheel 14, and nuts interacting with the screws and fixed to the blades x. When the diameter of the blades changes, the blades move along the sweeps, and the latter rotate, keeping the optimum blade angle, corresponding to the maximum installation efficiency. The rotation of the moves is carried out by a device containing coaxially located in the sleeve 5 with the shaft 3 and bevel gears in contact with the latter, which are mounted on the maxims 6. The current frequency stabilizer of the electric generator maintains it constant at any diameter of the wind wheel working with the maximum wind power utilization factor. 1 hp f-ly, 3 ill.
