FIELD: power engineering.SUBSTANCE: driving mechanism comprises a symmetric wing 1 arranged in an uneven flow of water with side walls 2, the axis 3 of which is installed in hinged supports 4 at rear ends of cross beams 5, connected by front ends through hinged joints 6 to a support structure 7, and also an actuating mechanism 9 connected with the axis of the wing 1 by means of a gear 8. The mechanism 9 is equipped with an elastic air cushion 11 arranged in the upper part of the wing 1 above water 10 filling its lower part 10, a lever 12, fixed on the wing 1, and vertical traction rods 13. Traction rods 13 are connected by lower ends with bearings 14 installed on the axis 3 and are attached by upper ends by means of springs 15 to the structure 7. Between the structure 7 and the lever 12 there are the following components installed in series - an elastic element 16 and a controller 17 of wing 1 position. In walls 2 there are holes 18. The top of the holes 18 is arranged below the upper point of the wing 1 profile and matches the level 19 of its filling water 10 and the lower border of the cushion 11, which is arranged in the form of an elastic shell 20, filled with air 21.EFFECT: higher efficiency due to parametric amplification of rotary oscillations of a driving mechanism wing.2 dwg |
