The invention relates to hydropower and can be used to convert the energy of ocean waves into electricity.

Known wave power installation comprising a submerged V-shaped pipe in the horizontal section where the hydraulic unit, and the generators outside of the plot (copyright certificate № 1401156, 1988, USSR).

The disadvantages of the known installation is that all of its design and components are under water, and it reduces its reliability and efficiency.

Known wave power installation comprising four side of the pontoon with rods, a vertical pipe with a generator (USSR author's certificate No. 1469202, 1989).

The disadvantages of the known installation is that the conversion mechanism with the electric contact with the water, which reduces the reliability of the installation and energy transfer at a distance.

Known wave power installation comprising a floating body streamlined, impellers having a concave blades and are mounted in the housing on horizontal shafts, four sprocket chain and belt drive connected to the generator (USSR author's certificate No. 1753013, 1992).

The disadvantages of the known installation is that all equipment, except electric generator, when the range of water and it reduces the reliability and efficiency of it.

Also known floating breakwater containing the pontoons are connected in pairs by means of hard links, and under the bottom of the pontoons attached stabilizing plate (USSR author's certificate No. 379725, 1973). This device reduces the energy of the waves, but does not have the tools and mechanisms to transform their energy into other forms of energy.

As a prototype can be assumed known from the technology of wave energy installation (JP 56092367 And 27.07.1981, F03B 13/16). However, the reliability and effectiveness is also reduced due to possible contact of the equipment with water.

The technical result consists in converting wave energy into electrical energy and improve reliability and performance is ensured by the fact that the wave energy installation comprising a bellows chamber, a duct, a wind wheel with blades mounted on a horizontal shaft, and generator, according to the invention is equipped with a pontoon attached to the bottom of the anchor chains, located on either side of it, and bellows, for example, rectangular cross section, with bellows camera attached on the bottom of the pontoon, and the top of the pontoon has a vertical duct of rectangular cross-section, split is the second partition on the same two channel, moreover, the bellows and the bellows chamber pneumatically communicated with the interior of the pontoon, in the context of partitions on a horizontal shaft installed wind wheel with radial spokes having at the ends of the concave blades, shaft mechanically connected via a coupling to a generator mounted on the outer rear wall of the duct.

In addition, the partition in the lower and upper parts of the front wind wheel, at an angle of 45°, attached to the guide plate, and the distance from the ends of the plates to the outside walls of the channels must be equal to the height of the blades.

The drawing shows a wave power plant, General view, with cut transformative part.

Wave power plant includes pontoon 1, the front end of which is attached to the bellows 2, for example, rectangular cross-section, and bottom bellows camera 3, pneumatically communicated with the interior of the pontoon 1. On top of the pontoon 1 is a vertical duct 4 of rectangular cross-section, divided by a partition 5 into two equal channel 6 and 7. In the lower parts of the channels in the cutouts on the pontoon 1, mounted flap valve 8 and 9, respectively, and the valve 9 is pressed by the flat spring 10. In the context of the partitions 5, on a horizontal shaft 11, is installed wind wheel with radial spokes 12, having at the ends of the concave is opasti 13. The shaft 11 is mechanically connected via a coupling to a generator mounted on the outer rear wall of the duct 4 (not shown). In the lower part of the channel 6 to the right wall above the valve 8 attached horizontal plate 14 made of an elastic material, and the partition wall 5, front wind wheel, at an angle of 45°, attached guide plate 15. In the upper part of the channel 7, before the wind wheel, the partition wall 5 is attached guide plate 16, and the distance from the ends of the plates 15 and 16 to the outer walls of the channels 6 and 7 must be equal to the height of the blades 13. The duct 4 has a top umbrella 17, attached to the rods 18. By the end of the bellows chamber 3 is rigidly attached to the longitudinal plate 19 made of an elastic material such as rubber. Front, the underwater part of the pontoon 1 is connected with two sides of the chain 20 with anchors 21.

Horizontal strap 14 promotes the return of the check valve 8 from a vertical to a horizontal position, i.e. working. Plates 15 and 16, attached to the partition wall 5, the compressed air flow in the channels 6 and 7 and the flat jet is pointed at concave blades 13 of the wind-wheel. This prevents the flow of the air stream from one channel to another, and up to 100% of the energy output and input in the pontoon 1 air.

Wave power plant works with edusim way.

Suitable for pontoon 1 wave compresses the bellows 2, lifts his front and rushes at the bottom of the outside of the pontoon 1, clutching at this bellows chamber 3. Longitudinal plate 19 creates an additional hydraulic resistance of the wave and thereby accelerates the compression of the bellows chamber 3. At this point inside the pontoon 1 is generated air pressure P1exceeding atmospheric pressure of RA, and the valve 8 back up and skip to channel 6 flow of air to the blades 13 of the wind-wheel, rotating it counterclockwise. In a moment of pause before the arrival of the next wave of the bellows 2 and the bellows chamber 3 will return to its original position (see the devil.) Inside of the pontoon 1 creates a negative pressure, i.e. the RA will be more P'1. Strap 14 will press the valve 8 and under own weight and the offset center of gravity will take the original horizontal position. Air under pressure RA channel 7 will go down on the blade 13 of the wind-wheel, rotating it counterclockwise, the valve 9 will recline down, and after equalization of air pressure inside of the pontoon 1 to the atmosphere, i.e. the RA, the spring 10 will press the valve 9 to its saddle. When you approach the pontoon 1 of the next wave, the cycle will repeat. Wind wheel will rotate counterclockwise and thereby continuously rotate the electric generator.

The proposed mouth of the mounting reduces wave energy and at the same time to obtain electrical energy. Arrangement of electric battery on the unit or on the beach will allow you to continuously provide consumers with electric power even in the absence of sea waves. Accommodation all moving and rotating parts, with the exception of the bellows and bellows camera, above the surface of the water improves the operating conditions of installation and reliability.
