The proposal relates to the field of electrical engineering, developing devices generate electricity from renewable sources.

Huge potential energy have tides and normal sea waves.

According to the magazine "Popular mechanics" No. 5 2011, p.6467 this energy is measured in terawatt.

A feature of these flows is that the flow changes direction both horizontally and vertically. In the same article mentions the wells turbine, which does not change the direction of rotation of the shaft when the direction of water flow. It also indicates that the turbine wells are prone to spontaneous failures of power and is characterized by a rather low efficiency.

Known turbine according to patent RU(11)2270932(13)C2 has the best characteristics. When changing the flow direction of the turbine shaft always rotates in one beforehand set design, direction. In addition, through the use of energy flow in the third quadrant it has an increased efficiency.

The disadvantage of this turbine is the difficulty of use in tidal and wave power plants, as the gearbox and generator have to do is immersed in the water flow, which increases the cost of the station.

The objective of this proposal is to eliminate the proposed tidal Volno the second plant of the above-mentioned drawback and to preserve the dignity of turbines in the previously mentioned patent.

This technical result is achieved by the fact that tidal wave power plant is built on the basis of two turbines, each of which has at least two disks connected by the axis on which the hinged blades, the movement of which is limited to the primary and secondary latches. Both turbines are pivotally mounted on a common axis, fixed in the frame, part of which is fixed at the bottom, and the other part includes the area on the surface where the gearbox and the generator, with one turbine main tabs are on the right side of the blades, while the other turbine main tabs are on the left side of the blades. Adjacent turbine disks provided with a main bevel gears, between which there is an additional bevel gear pivoted on an axis perpendicular to a common axis turbines, and one of the additional bevel gears rigidly attached to the shaft, facing to the platform on the surface.

The invention is illustrated in the drawings, showing:

Fig. 1 - scheme of tidal and wave power;

Fig. 3 - design of turbines along the section A-a in position 45;

In position 0, indicated in figure 2 and figure 4, the blades 5, the fixed main tabs 6 across the stream, creating a torque directed opposite, since the main tabs 6 in one turbine located on the right side of the blades, while the other is located on the left side of the blades.

In position 0 of the other blades are located along the stream and in creating moments are not involved.

In position 45, indicated in figure 3 and figure 5, the blades 5, the fixed main tabs 6, create torques, so that the turbine 1 and 2 rotate counter. Moreover, the blades 5, additional fixed clamps 7, increase these moments.

Torques through the connecting axis 4 is transmitted to the power 3 disks. To Magnum power disks rigidly fixed to the gear-differential 15, the construction of which is shown in Fig.6.

Power discs 3 through bearings mounted on the fixed axis 8, which passes through the fixed axis 14 with a hinge mounted on it an additional bevel gears, the rotation of which is transmitted through the main bevel gear rigidly connected with the adjacent power turbine disks.

With a complementary bevel gears rigidly connected to the shaft 13, which provides the gear 11 and the associated generator 12.

It is important to note that in all flow directions (except the direction in "the end") design provides a unidirectional rotation of the generator and has a higher efficiency due to the use of energy and on the counter flow in the third quadrant of operation of the turbines.
