The disadvantage of this device is that used layout and strengthening axes with blades provides weak positional stability of the blades on the flow of the medium. The latter is due to the fact that the axis fasten the console to the chain, and the chain has a certain flexibility in the rotation plane and in the transverse direction from the effects of lateral loads (offset flow, lateral flow, and so on). As a result, the blade moving constantly changes its position, shifting from the vertical under the action of not only pressure on the flow of the medium, but side efforts. As the boron power.

The present invention is directed to the solution of the technical problem to ensure positional stability of the blades in the open position due to the formation of a multi-point support system and exclude the effect of lateral loads due to the localization device in the frame. Achievable technical result is the most complete energy recovery environment with minimal design complexity.

These characteristics are essential and interrelated with the formation of a stable set of essential features, sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example, which, however, is not only possible, but clearly demonstrates the possibility of achieving a given set of essential features required technical result.

The drawing shows a General diagram of the device.

According to the invention embedded in a medium with retention from movements in the past along current flow device for selecting the energy of the current environment contains flexible working body in the form of an endless chain or rope spanning the pulleys, some of which are located on the shaft of the PTO or linked kinematically with PTO shaft driving the energy consumer. The working body is equipped with blades made in the form of two valves each, swivel mounted on axes perpendicular to the direction of flow of the current, when said blades are connected with the axes for folding the rotation around the axis when moving against the flow and riskladen flexible closed elements, covering the pulleys located on the shaft of the PTO or related kinematically, for example, through the transmission gear (or other transfer - belt or chain drive), and the pulleys located on the additional shaft parallel to the shaft of the PTO. Last pulleys can be located on a separate, additional shafts-axis.

Each axis each of the two valves are installed perpendicular to the direction of flow when moving the blade along the stream and its middle part is fixed on a transversely located rigid element, the ends of which through direct flexible rod connected with a flexible closed elements, and other transversely located element associated with the flexible elements. These shutters are designed to be folded by rotating around the axis when moving against the flow and unfolding with the formation based on the transversely located first rigid element of the blade when moving along the stream environment. Each axis of each of the two shutters is additionally connected with other transversely-located elements of direct thrust that is installed with the possibility of free-wheeling relative to this item. The device has a frame located in Vertica updateh elements, the elements of which are mounted the shafts and pulleys, and a flexible closed elements are made of equal length greater than the distance equal to the sum of the semicircle of the pulley on the shaft of the PTO, the semicircle of the pulley on the additional shaft and dual center-to-center distance between the pulleys. With such design, and vertical positioning relative to the flow of the medium frame, stretched along the length (height), vertical flexible elements are extruded along the stream and are balanced in the free position in the water, as shown in the drawing.

Below is an example of a specific implementation of the device in relation to placing it in the aquatic environment.

The device is installed along the flow stream. The device comprises a tubular open on all sides of the elongated frame parallelepipedal form located in the flow vertically upwards in length. Its elements can be mounted parallel to each other mounted for rotation shafts which are rigidly connected with the pulleys 1 and 2, respectively. One of the shafts may be kinematically connected with the shaft 3 PTO-related energy consumer. These shafts may be missing. Pulleys strong example of execution.

Pulleys are covered by the endless flexible elements 4, which can be used a rope made of synthetic materials, and when the toothed pulleys or sprockets used the endless chain. While the flexible elements 4 are of length substantially greater than the desired length to provide bending around the pulleys and forming the transfer function of rotation. When the location in the fluid flow of this design flexible elements are fond of flow and provide the desired contact with the pulleys, and the desired tension. The latter is also enhanced by the interaction of water in the stream with the sailing elements of the device.

Two flexible element 4 are connected transversely disposable rods 5, the ends of which are connected with flexible rods 6, as separate links connected by hinges 7 with rope or chain (flexible element).

With the Central part of each transverse rod 5 is firmly connected to one end of the axis 8 of the blades, which is the axis of rotation (turn) the type of book two valves 9, which form the blade in the form of a sail element.

Each of the valves 9 are made in the form of a sail of reinforced synthetic fabric on a rigid metal frame and obreshetiny with the possibility of folding the rotation around the axis 8 when moving against the flow and unfolding with the formation based on the transversely disposed rod 6 of the blade when moving along the stream environment. Fold among themselves or with the axis 8 can be associated gear 10.

With this design of the device, the energy of the current environment through the opened blades across the stream will be converted, for example, in electric when working stroke of the flexible elements, with folded blades in idle mode with minimal resistance returns to its original position.

The frame of this device captures the spatial relative position of the shafts with pulleys and flexible elements.

The device operates as follows.

Being in the unfolded state along the course of the stream, such as a river, at some depth, sufficient for unobstructed passage of ships, sash, opened under the pressure of flow, pressure is exerted on the transverse rod 5, transmitting force through the flexible elements 4 on covering their pulleys 1, which rotates the shaft 3 connected kinematically, for example, a generator or other device such as a pump (not shown).

When this straight rod 11 connected to one end of a transverse bar 5 or axis 8 on the rod and at the other end with the possibility of free running with the other transverse bar 12 defines a strictly vertical polojenieto 6 open the blade on an axis 8 by means of rods 6 gradually changes the angle from the 90owith respect to the direction of flow at 0oand becomes the bottom edge of the stream, is smoothly and with minimal resistance when folded, returns to idling ago. Then folded the blade, following the circle, gets into the flow, which it reveals, and she, putting pressure on the transverse rod 5, makes another stroke.

The present invention is industrially applicable, because its production does not require the use of special technologies, in addition to those used in mechanical engineering in the manufacture of gears with flexible elements and shipbuilding in the production of sailing equipment.
