Summary: | The invention relates to wind energy conversion devices, in particular to vertical axis wind turbines with aerodynamic protection against overloads.The wind turbine, according to the invention, comprises a tower (1), on which is installed an electric generator (10) with a rotating shaft (7), connected to a rotating shaft (2) with blades with an aerodynamic profile (3), made inclined and mounted movably with the possibility of automatically changing the angle of attack α by turning. The blades (3) are connected to the rotating shaft (2) by means of radial rods (4), at the peripheral ends of which are installed mechanical hinges (5, 6), axially spaced from each other.
Invenţia se referă la dispozitive de conversie a energiei eoliene, în special la turbinele eoliene cu ax vertical cu protecţie aerodinamică împotriva suprasarcinilor.Turbina, conform invenţiei, conţine un turn (1), pe care este instalat un generator electric (10) cu un arbore rotitor (7), unit cu un arbore rotitor (2) cu pale cu profil aerodinamic (3) executate înclinat şi montate flexibil cu posibilitatea autoschimbării unui unghi de atac α prin pivotare. Palele (3) sunt unite cu arborele rotitor (2) prin intermediul unor bare radiale (4), la extremităţile periferice ale cărora sunt montate articulaţii mecanice (5, 6) axial distanţate una faţă de alta.
Изобретение относится к устройствам для преобразования энергии ветра, в частности к ветротурбинам с вертикальной осью с аэродинамической защитой от перегрузок.Ветротурбина, согласно изобретению, содержит башню (1), на которой установлен электрогенератор (10) с вращающимся валом (7), соединенным с вращающимся валом (2) с лопастями с аэродинамическим профилем (3), выполненными наклонно и установленными подвижно с возможностью автоизменения угла атаки α путем поворота. Лопасти (3) соединены с вращающимся валом (2) посредством радиальных стержней (4), на периферийных концах которых установлены механические шарниры (5, 6), отстоящие в осевом направлении относительно друг друга. |
