The invention relates to the field of electricity and can be used to produce environmentally friendly electricity by converting the energy of sea waves (including tidal).

Recently, the energy shortage has become an international problem, the development of the economy and, as a consequence of increasing consumption forced to seek new sources of energy.

There are various solutions to this problem.

First, due to the burning of traditional energy resources: coal, oil and gas, i.e. doubling (tripling, etc.) production and combustion of combustible carbon-containing minerals and therefore huge amounts of the emissions of CO2(carbon dioxide, greenhouse effect).

Secondly, due to atomic energy. Of course, nuclear power is the way out of the problem, but where is the guarantee against the recurrence of the Chernobyl disaster, and this is not a cheap and quick procedure.

Thirdly, in the future "hydrogen energy". But hydrogen is not a primary energy source, and to talk about its application in the energy sector is possible only at very cheap and environmentally friendly generation of electricity. Only under this condition it is possible to establish economically viable hydrogen production, decomposing by the electrolysis of water.

So civilized and reasonable and reliable in the e time to solve the problem of power supply to consumers, considering the fact that the number of raw materials, renewable energy sources, you must contact the energy saving technologies and renewable energy sources. The use of renewable energy sources such as solar, movement of air and water, geothermal energy, and other natural phenomena, is the basis of alternative energy.

Thus, for solving the above problems has been proposed wave power plant using the energy of the waves.

The closest to the technical nature of the claimed invention is a device for the energy of the fluid (SU 1581851 A2)containing a turbine, a generator and a series of radially arranged at different levels in tanks. Installed rotatably on a horizontal shaft and consistently communicated among themselves by means of diametrically spaced channels. Capacity on the one hand have the intake, and on the other, discharge nozzles, the volume is made variable, decreasing from the inlet to the pressure tube, a turbine mounted for rotation in the direction opposite to the rotation of the containers connected to the generator rotor and the stator of the latter is connected with a horizontal shaft, with the aim of increasing efficiency, the device is provided with polymorphism, covering a shaft mounted for rotation therein and is divided by vertical partitions into a sealed section, a shaft provided with a shoulder crowns located in each section, the channels made in the form of tubes, each of which consists of two parts interconnected by means of the swivel mechanism can be rotated in the direction opposite to the rotation of the containers, tubes of each row of containers is connected to the hull sections on opposite sides of partitions.

The disadvantages of this device is generating electricity is the presence of numerous buoys, the presence of a complex system of discharge of the working fluid and drives the generator, there are many pipes and pipelines, the frequency instability of electricity generated.

The required technical result is the wave power plant of this design, which will allow efficient way to convert input energy of the waves into electricity, and change the settings of the applied energy (amplitude and repetition frequency of the waves, the height of the lifting/lowering of water) to a lesser extent affect the parameters of the received electric power in comparison with the prototype.

Wave power plant comprises a turbine generator, a wave energy Converter, converters sunk to the bottom and is made in a V is e a truncated cone or pyramid with cutouts, to ensure the delivery of water to create excessive pressure of the working fluid located in the upper narrower part converters, the working fluid through the piping acts on the turbine blades connected to a generator.

The required technical result is achieved by the fact that in the proposed device, the input wave energy increases the pressure of the working fluid in the Converter unit input wave energy (1) energy of the working fluid flowing in the circuit pressure (2)acting on the turbine blades connected to a generator (3). A device converting energy input waves (1) are the casing (4) in the form of truncated cones or pyramids with cutouts (6), sunk to the bottom and connected by piping (5). Openings in the transducer housing is designed for the flow of water and create excessive pressure of the working fluid located in the upper narrower part converters.

The invention is illustrated by drawings, where figure 1 shows a possible variant of the device of the wave power plant, and contains:

1 - device transformation of the input wave energy into the energy of the working fluid;

2 - circuit pressure;

3 - turbine generator.

Figure 2 presents a possible variant of the Converter input wave energy, containing:

- the device conversion;

5 - piping;

6 - cut-outs.

A transducer is a device, which is received through holes (openings) water creates excessive pressure of the working fluid located in the upper narrower portion of the device.

Wave power plant operates as follows: the waves constantly change the level of the sea level change leads to changes in the pressure in the unit conversion (1). A device converting energy input, overheated or located at the bottom along the coast, in areas with increased activity of the sea. Wave energy affects the stationary energy converters, raising the pressure in the pipe (5) of any of them, and, as a consequence, changes of pressure in the circuit pressure (2). The working body, moving in the direction of low pressure comes on the turbine blades connected to a generator that produces electricity.

After exposure to the blades of a turbine working fluid is supplied to any unit, where due to the rollback of a wave in a vacuum.

Wave power plant containing a turbine generator, a wave energy Converter, the working medium through which pipelines acts on the turbine blades, characterized in that the transducers are submerged on the bottom and the implementation of the s in the form of a truncated cone or pyramid with cutouts, to ensure the delivery of water to create excessive pressure of the working fluid located in the upper narrower part converters.

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.

EFFECT: wider functional capabilities of a power installation with orthogonal turbines.
