The invention relates to hydropower, in particular to the means for converting energy of the reverse flow of fluid, for example, in devices that use the energy of the waves.

A device used to obtain energy from the motion of sea waves, containing a wheel with a hub and concentric with the hub of the rim connected with the latter by means of radial spokes, which are installed with the possibility of limited bilateral rotation of the rotor blades, the energizing reverse flow caused by periodic movements of the wheel connected to the float, while the wheel rotates without changing direction, changing the direction of flow (allow the new energy to install a large capacity, because increasing the wheel diameter, respectively, increasing the dimensions of the blades, the size of which is limited by their strength.

Closest to the claimed means for converting the energy of the reversible fluid is turbine-driven waves. This turbine includes a wheel with a hub concentric with the rim connected to the hub and to each other via a radial spokes, and the vanes are mounted concentric rows with limited rotation on the spokes (UK application N 2081388, CL F 03 13/12, 1982).

With this turbine is possible to provide a large capacity, because the blades are concentric rows, and the number of blades increases from the inner row to the outside, but the turbine is not provided simultaneous relaying of blades from one extreme position to the other, which impairs the efficiency of use of the fluid flow.

The technical result of the claimed means for converting the energy of the reversible fluid is providing simultaneous transfer of all the blades from one extreme position to the other, allowing you to more fully extract the energy.

In Fig. 1 shows a top view of the means for converting the reverse flow of the fluid; Fig. 2 cross section of the blade of the tool of Fig. 3 cross section of the blade sinusoidal form with a smooth sine of Fig. 4 is the same, with the acute-angled views.

Means for converting the energy of the reversible fluid contains a wheel with the hub 1, the concentric rims 2, 3, 4, connected to the hub 1 and interconnected by radial spokes 5 and blade 6 mounted concentric rows with limited bilateral turn on the spokes 5, and the arc lengths of the outer end surfaces of the blades in each row are made equal to each other. To limit rotation of blades can be used restrictive lugs 7, as the limit stops can be used and springs (Fig. not shown).

Means for converting the energy of the reversible fluid works as follows.

At clash of the reverse flow of the fluid on the blades 6 of the last turn on the sterile at the optimum angle of attack depending on the speed of crowding of the fluid. When the wheel retains its unidirectional rotation regardless of the direction of the fluid. As the blades 6 are almost completely overlapping the cross section of the wheel and made extending to the periphery, the speed of their transformation from one extreme position to the other will be determined by the magnitude of the arc length of the outer end surface 6 in each row, therefore, to ensure the synchronisation of data arc lengths are made equal to each other. The implementation of the blades 6 a cross-section of a sinusoidal type allows to increase the area of interaction with the fluid medium, which contributes the most complete selection of energy, and the sine wave can have a smooth or sharp appearance, depending on the technology of blades 6, for example, by stamping it runs smooth, but when welding acute-angled. Additionally, the location of the spokes 5-axis sine wave allows you to increase the strength of the scapula.

Unidirectional rotation of the wheel can be transmitted to the rotor al. of the generator to produce electricity. energy can be used multiplier.

2. Means under item 1, characterized in that the blades are made with a cross-section of sinusoidal form, and the spokes are located along the axis of the sine wave.
