Abstract

Изобретение относится к турбине, предназначенной для выработки гидроэлектроэнергии, включающей два лопастных колеса (11, 12, 31, 32), последовательно расположенных в патрубке турбины (10, 21) в качестве переднего колеса (11, 31) и заднего колеса (12, 32) относительно направления потока (23) вдоль общей оси вращения (30), проходящей по направлению потока (23), колеса (11, 12, 31, 32), установленные с возможностью вращения в противоположных направлениях, приводимые в движение потоком воды, а также предназначенной для работы в соответствующей гидроэлектростанции. Для улучшения характеристик турбины с целью выработки гидроэлектроэнергии, в частности для выработки энергии в условиях низкого напора, изобретение предлагает, чтобы первая шестерня (46) и вторая шестерня (47) располагались вдоль оси вращения (30), каждая из шестерен соединена с колесом (11, 12, 31, 32) и шестерни взаимно соединены через зацепляющий привод (48), так чтобы переднее колесо (11, 31) и заднее колесо (12, 32) были бы связаны друг с другом, что касается их скорости вращения, при этом зацепляющий привод (48) установлен с возможностью подключения к генератору.
