The invention relates to hydropower, in particular to a device for converting energy of water streams and sea tides into electricity.

Known blade-anionicity rotation. Each fold is made in the form United with the shell frame with a system of intersecting strings, and the rotation stops made in the form of a flexible rod, fixed ends on frames (ed. St. N 1255737, CL F 03 D 3/00, 1986).

The disadvantages of the known installation are as follows: 1). When folding the frames of two valves flexible sheath when moving against the wind create excessive windage, which increases aerodynamic resistance during reverse motion of the blades. This leads to reduced efficiency. 2). The use of blades in the aquatic environment possible. This reduces the functionality of the installation. 3). In operation, the blades possible mechanical damage to the flexible membrane and its unstable operation, such as when water and snow precipitation, and dust pollution, especially chemically aggressive, and in the case of precipitation weigh the weight of the blades, as the flexible membrane to become clogged with snow or water.

The closest technical solution, selected as a prototype, is an energy installation comprising a casing provided with a rotor mounted on the shaft and having blades made in the form of rotary blades.

Spokes extreme rims of each impeller are limiters of rotation of the plates of each blade and stops during the stroke of the blade. According to the invention, the average rim of each impeller provided with a stiffening rib, which places the upper ends of the folding plates each blade has two-way electromagnetic damper-retainer containing at least two cushioning Shoe with restrictors movement, within which is placed a spring, and the coil of the solenoid is located inside the ribs.

Power plant is mounted on a pontoon platform 1 (Fig. 1 and 2), which contains industrial and domestic premises. The production facilities include: generator, 2 wells 3 and the camera 4. In the generator room 2 are electric generators (primary and backup), batteries, winches lifting and etching anchors, heating system. From the generator room there are 2 hatches for access to the bearing element connecting the shaft with energorashodyi device.

Under the pontoon platform 1 (Fig. 2) below the water level and the maximum thickness of freezing water in the winter is the rotor, made in the form of at least two wheels 5 mounted on a common shaft 6, which predatory chain is transmitted to the gear shaft of the electric generator.

Each impeller 5 includes a hub 7, (Fig. 4-6) which with the help of at least three parallel rows of spokes attached three of the rim 8, 9 and 10. Spokes 11 (Fig. 3) middle of the rim 9 of each of the impeller 5 are the axes of rotation of the blades, made in the form of at least two plates 12 and 13. Plates 12 and 13 each blade pivotally mounted on the spokes can be rotated at an angle not exceeding 90aboutin opposite directions perpendicular to the axis of the impeller 5. Spokes 14 (Fig. 4-6), extreme rims 8 and 10 of the impeller 5 are limiters of rotation of the plates 12 and 13 of each blade and stops during the stroke of the blade.

The rib 15 of the middle rim 9 (Fig. 3) of each of the impeller 5, the upper ends of the folding plates 12 and 13 of each blade, installed two-way electromagnetic shock absorber clamp designed to secure the folding and holding plates 12 and 13 of the blade at an average rim 9 at idle and repulsion plates 12 and 13 of the blades at the beginning of the stroke to accelerate their spread. Two-way electromagnetic shock absorber clamp consists of two cushioning Shoe 16 with restrictors movement inside which is placed the spring 17 senjem winding winding, closed on both sides of the lid 20 with seals that protect the windings from moisture. Inside the middle of the rim 9 canal, which houses the power cable 21 with branches to the solenoid coils (number of blades). The holding plates 12 and 13 of the blades in the idle mode is automatically adjusted to their transition into the working area (by changing the polarity of the electromagnets plates 12 and 13 of the blades proceed in different directions).

When placing a power plant on the river (Fig. 6) consider the constant direction of flow for the selection of the optimum depth of immersion of the impeller 5. One end of the driving shaft 6 is located in the bearing 22 located on the rack 23 mounted on the base 24, placed on the river bottom. The other end of the drive shaft 6 passes through a bearing unit with seal 25 in the coastal well 26 has at the end of the drive sprocket and a chain transmission transmits rotation to the gear shaft of the electric generator installed in the generator on the banks of the river.

Power plant attached to the river or seabed four anchors 27, the installation location of which are indicated buyreply (Fig. 1). On the deck of the pontoon is yaytsa chain during transport position when towing.

Power plant works as follows.

When the rotation of the impeller 5 in the direction of water flow on one side of the plates 12 and 13 of the blades fully disclosed (the area of the stroke), while the other half of the blade plates 12 and 13 are compressed and fixed relative to the average of the rim 9 (area of idling). As each blade of the zone idling plates 12 and 13 are repelled from each other by changing the polarity of the electromagnets of the absorber - retainers and springs 17, and under the action of a moving fluid mass touches the spokes extreme rims 8 and 10 of the impeller 5, creating a torque transmitted on a common shaft 6, with which the mechanical rotation is transmitted to the shaft of an electric generator that produces electrical energy.

Power plant (onshore option) can be placed on the river with a water flow rate of not less than 3 km/h, while the impellers 5 should be placed below the level of seasonal freezing water.

When placing a power plant (or several) along the coast to use tidal currents depending on rainfall, the location is chosen saliva or low tide since this changes the position of the idle zones and stroke on the opposite (Fig. 4 and 5).
