FIELD: water-power engineering. ^ SUBSTANCE: invention refers to water-power engineering, and namely to fluid medium energy utilising devices, and can be used for energy conversion of fluid medium flow, e.g. river flow, into electric one, whereby momentum energy of flows is converted into translation-and-vibration movement. Fluid medium energy utilising motor consists of a frame with a window, which is submerged with its longitudinal side across the medium flow and is fixed on foundation. Load-carrying member with working member is installed in the frame so that it can move. Working member is intended for being effected by fluid medium. It is fixed with its central part in the load-carrying member, and when in operation, it is installed angle-wise to the flow direction. Motor comprises a working member position changing device as well as hydraulic force transformer. Load-carrying member is installed so that it can move in a back-and-forth manner in the frame window along its longitudinal sides. Working member made in the form of a wing with a hydrofoil profile is installed on the load-carrying member axis so that it can turn about the axis and interact with fluid medium flow. Blade position changing device is made in the form of the blade turning stops symmetrically installed on the frame longitudinal side. Hydraulic force transformer is kinematically connected with load-carrying member. ^ EFFECT: invention allows increasing motor efficiency and simplifying motor design. ^ 2 dwg |
