The invention relates to hydro - and wind energy, in particular, to devices for energy extraction fluid for converting it into electricity.

Known channel unit described in the ed.St. N 1129403, CL F 03 B 13/10, 1984, which contains the transverse turbine with two blades connected to a generator. This machine is intended for extraction of energy from the fluid flow of small capacity and to increase the power output requires focused concentration, flow, Thu the config [1] and contains a vertical shaft with a fixed cylindrical sections, split disk holders, and profiled blades parallel to the shaft and attached to the holders at least two rows of concentric circles.

The disadvantage of the prototype is that the blades of the engine have great resistance to their flat part in the movement towards the incident flow, which reduces the capacity and efficiency of the engine.

The aim of the invention is to increase the power and efficiency of the engine by profiling blades, ensuring the best use of the energy flow of the concave part of the blade decreasing the resistance of rotation under the influence of flow on their convex part.

The objective is achieved by profiling each blade is made in the form of two connected arcs of different radius, and arc of larger radius is placed closer to the shaft, and chord arcs are mutually perpendicular and are angled at 45aboutto the radius drawn from the axis of the shaft to the outermost edge of the blade.

In Fig.1 shows a device for the extraction of energy, fluid, General view; Fig.2 and 3 shows the profile of the blades and their location on the disk holder.

Device for selection of energy is established between the disk holder 4, moreover, the lower holder 4 is made more durable.

A device for selecting the energy of the fluid as follows.

Depending on the required power is determined by the number of sections. When exposed to water flow or wind on section 2 of the shaft 1 has a unidirectional rotation. To change the rotation direction, it is sufficient to turn the device. Torque on the shaft 1 is determined by the flow pressure on the concave side of the blades 3, and the resistance of the convex parts is reduced by giving them a streamlined shape in the form of semi-circle and orienteering holders 4 chord of its arc at 45aboutto the radius drawn from the axis of the shaft to the outermost edges of the blades 3, and the arc of larger radius semi-circle is placed closer to the shaft 1, which allows to optimize the dynamic characteristics when working stroke of the blades 3. The design of the device has a rigid shape, which increases the reliability of its work.

These advantages of the device for the energy of the fluid can consider it promising for use in generating units that are placed in the water below sets winter ice close to each other in the plain is. While the generators must be placed in sealed capsules and synchronized with the network, which they feed.

In addition, the described device can be used for selection of wind energy, together with the generators they can be placed close to each other on the hills and even the roofs of houses, as they have a low windage.

An advantage of the invention is a full environmental clean, simple and robust design, as well as the possibility of combining (summing) the energy of many units in the selection of their use of wind energy and virtually all water flows without expensive construction of dams on rivers and flooding of the land.

The DEVICE FOR selecting the ENERGY of a FLUID MEDIUM, comprising a vertical shaft with a fixed cylindrical partitions of disk holders, and profiled blades parallel to the shaft and attached to the holders at least two rows of concentric circles, wherein the profile of each blade is made in the form of two connected arcs of different radius, and arc of larger radius is placed closer to the shaft, and chord arcs mutually feather blades.
