The invention relates to the field of hydropower and is designed to produce electrical energy by converting kinetic energy of ocean waves into electrical energy.

Known coastal river hydroelectric power plant, comprising a housing made in the form of betonirovannaa shore, half accommodated in the housing bladed turbine, located on an axis that is installed in a concrete base, coupling and generator (patent RF №2020260, MKI F03B 7/00, published 1994.09.30). Case specified hydroelectric power plants equipped with guide rails placed behind the wheel downstream of the river, and a partition with floats installed to move along the guides. And the axis of the turbine is vertical, clutch and generator located above the level of the river, and the width of turbine blades made more difference between the maximum and minimum levels of the river. However, the construction of hydroelectric power does not allow you to fully use the power of water flow, as in the working area gets only half of the turbine blades, which reduces the efficiency (coefficient of performance) of the structure. In addition, the construction of hydroelectric power depends on the water level on the river.

Known wave power plant, consisting of Anoprienko, gutters, wheels, Mach is the AC and generator (patent RF №2227844, MCI F03B 13/18, F03 13/22). Work the body in the form of three wheels with blades that are installed above the horizontal groove which moves foamed wave, while the impellers are able to rise above the gutter, depending on wave height. Impellers transfer the torque to the flywheel through a chain drive and overrunning clutch. The flywheel stores the energy, thereby smoothes the frequency of crowding waves and uniformly transmits the rotation to the generator with automatic variable speed. Wholeplant equipped with underwater breakwater plate which is capable of changing the depth of immersion, to create the conditions for the collapse of the wave heights at the desired point in the impeller.

The closest technical solution is the wave installation comprising an impeller, a generator and wholeplant, located behind the impeller in the direction of the waves (DE 4438400 A1, 02.05.1996, F03B 7/00).

The disadvantage of these constructions wave setup is that if you are not using a reverse wave power, which does not allow to get the maximum amount of electrical energy.

The objective of the invention is to fully use the kinetic energy of ocean waves to generate electricity.

In the invention this is achieved due to the fact that in the wave setup containing the impeller, generator and wholeplant, located behind the impeller in the direction of the waves, according to the invention wholeplant one end pivotally connected to a support on the shore, and the second with the help of the holders rigidly connected to the pontoon, with the impeller by means of holders rigidly attached to the pontoon.

Figure 1 shows the wave installation, General view, figure 2 is a side view, figure 3 - top view.

Wave setup contains the impeller 1, which, by means of the bearing 2 is connected to the generator 3, and with the help of the holders 4 is rigidly fixed to the pontoon 5. Wholeplant 6 is located behind the impeller in the direction of the waves and at one end by means of the hinge 7 is connected with a support 8 on the shore, and the second holder 4 is rigidly connected to the pontoon 5.

Wave setup is as follows. The incoming wave is lifted by means of the pontoon 5 on the impeller 1, which gives it a rotary motion. Then the wave moves to wholeplant 6 moves to its end, and then rolled in the opposite direction to Anoprienko 6 to the lower part of the impeller 1, causing it to rotate. Between the impeller 1 and Anoprienko 6 there is a gap equal to half the radius of the impeller 1. All wave energy is transferred to mechanical energy of rotation of the impeller 1, which is connected to the generator 3 through a terminal connection or lead the 2 IR. Pontoon 5 contributes to raising the impeller 1 to the axis of the impeller 1 is always positioned above the water level. In addition, the pontoon 5 contributes to raising the height of the waves.

The proposed construction of wave setup allows maximum use of the energy of motion of sea waves and thus increase the amount of electricity generated.

Wave setup containing the impeller, the generator and wholeplant, located behind the impeller in the direction of the waves, characterized in that wholeplant one end pivotally connected to a support on the shore, and the second with the help of the holders rigidly connected to the pontoon, with the impeller by means of holders rigidly attached to the pontoon.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.
