The invention relates to hydro - and wind energy, in particular to a device for selecting the energy of the fluid, mainly water flows and wind, for subsequent conversion into electricity.Known wind turbines for U.S. patent 5044878 from 3.09.91, MCI F 03 D 3/02, comprising a vertical shaft attached to it two cylindrical sections with upper, intermediate and lower holders, between which are fixed three blades located radially and parallel to the shaft, which consist of three flat palapala. The disadvantage of the wind turbine is that its base cannot be built windmill significant capacity due to the large resistance of the flat polopoly during their return movement towards the wind, and this reduces the efficiency and capacity of the unit. Because of the flat design palapala unit may not be used for selection of energy of water flow, because large compared to the air density and viscosity of water inhibition of palapala at reverse motion in the water will be extremely high.The technical result of the invention is to simplify and cheapen the device for selecting the energy of the fluid is CSOs depending on the power and diameter of the device increasing the number of outer blades optimal size without angular gaps between them or with some mutual angular beams, to the blades moving in the working position the concave sides to the stream environment and constantly replacing each other due to the rotation of the device under the action of a stream, did not make it useless breakthrough among themselves, used its width is greater radius of the device and to minimize flow resistance convex sides of the blades when they return to the working position, because they are in this case follow close behind each other and each preceding blade and especially the first one, even for a short time greeting the incoming flow and turned to him in this most acute and narrow part weaken its effect on subsequent blades.In Fig. 1 shows the proposed device, the vertical section, the view from the top.Strokes presents the first modification of the blades.

Unlike previous: the mechanism of energy transfer rotation to the generator and the generator without sealed capsules are below sections.In Fig. 5 shows the placement of the device in deep water along the river banks with preservation of the fairway. As closer to the middle of the river the water velocity above the left Bank downstream of the hosted device with rotation counter-clockwise, right clockwise. Figures 5 and 9 shows the connecting device of the base and top design for stability devices. Figure 12 obrazuetsa, summed up, is synchronized with the current network and then fed into the network 19 to consumers.In Fig. 6 shows the placement of the device on the bottom along the shore of a navigable Bay, which regularly occur and tides; Fig. 7 placement of the device in elevated position; Fig. 8 placement of devices on the roofs of buildings of different configurations of Fig. 9 a vertical section of the platform for the selection of the energy of the sea and ocean currents (along its length placed 5 devices); Fig. 10 shows a top view of the four platforms in the sea or ocean, on each platform 15 devices.The device consists of a shaft 1 of energy extraction, cylindrical sections collected from the upper and lower holders 3 with fastened between the blades 2.Each blade of Fig. 1 and 2 consists of two connected arcs of different sizes. The blade 2 between the holders 3 strengthened in line with the binding at the outer edges of the outer circumferences of the holders 3, the profiles represent two paired arcs of different sizes convex sides clockwise, at the far point of the smaller arc is located on the outer circumference of the holder 3, its other extreme point is a point pair with a large arc and odnovremenno 1 to the first point, another extreme point greater arc serves as the point of intersection with the chord drawn from the point of its mating with the lower arc angle 90othe last chord counterclockwise, such design of the blades 3 provides maximum flow pressure on the concave side of the blades 2 in their course work and minimum resistance convex sides at the back of the blades 2 in predebate position and respectively rotating the device clockwise when getting it flow from any direction, to rotate counterclockwise enough to turn the entire device or only section, so that the top became the bottom and bottom-top, the blade 2 overlap each other by a Central angle and do not allow useless breakthrough flow between them, he uses a width greater range of devices, depending on the values overlapped each blade 2 of the Central angle and the angle between them, the device has a 5 modifications.First modification: each blade smaller arc with its chord overlaps the Central angle of 3.75o, large arc with its chord in 11,25othe blades on the Central corner are separated from each other by 7.5otheir number around the circumference of 48.
, large arc with its chord 22,5othe blades on the Central corner are separated from each other on the 15otheir number in circumference 24.Third modification: the blades on the Central corner are separated from each other by 22.5otheir number around the circumference of 16.The fourth modification: each blade smaller arc with its chord overlaps the Central angle of 7.5o, large arc with its chord at 45othe blades on the Central corner are separated from each other by 22.5otheir number around the circumference of 16.The fifth modification: each blade smaller arc with its chord overlaps the Central angle of the 15o, large arc with its chord at 45othe blades on the Central corner are separated from each other by 22.5otheir number around the circumference - 16.By varying the dimensions of the blades with a smaller arc from the 3o15oand more arc more smaller arc from three to six times and angles offset between the blades in 7,5, 9, 10, 12, 15, 18, 20 and 22.5oi.e. on the corners that are placed in the circle in 360ointeger number of times, with the required angular overlapping lobes each other or, at least, without angular gaps between them achieved the maximum efficiency of the device. When shifting effektivnosti device falls, because when frequent location of the blades, the flow of water or wind when working stroke of the blades are pressed only on their outer parts, too rare blades increases the resistance of their return stroke.On devices with the specified configuration of the blades and their placement in the holders of the flow of water or wind can come from any side, in Fig. 1 and 2 for ease of description this area shows only one side, they will rotate clockwise when viewed from the top down. To ensure rotation of the device counterclockwise enough to turn their sections.In Fig. 3 and 4 show vertical sections of the power unit for selecting the energy of water flows and wind with the above devices of three sections with the shaft 1, the holders 3 and implied, but not painted blades.
