The lower elements connected with coastal with rods support with the ability to co-move with pontoons. 2 Il. The invention relates to hydropower, in particular to the wave energy installations.Known wave power is tiplication and generator, hollow pontoon ballast and outer edges at the bottom and a vertical support rod, the upper end of which is kinematically connected with the input shaft of the multiplier, and the bottom with the pontoon.The disadvantage of this setup is small efficiency, because it uses only surface wave power when the movement of the pontoon from foot to crest vertical.The purpose of the invention is the increased efficiency of the installation.In Fig. 1 shows a General view of the installation of Fig. 2 - the design of the edges of the pontoon.The apparatus comprises a platform 1 (Fig. 1), the multiplier is 2, the generator 3, the pontoon 4, the ribs 5, rod bearings 6, additional pontoon 7, the pile 8, Hoop 9 with inclined radial spokes 10, the opening 11 in the platform, the hole 12 in the pontoons 4, 7 (Central and two lateral), horizontal beams 13 elements 14 of the ribs 5 (Fig. 2), the plates 15, 16 vertical and horizontal rod 17, the connection 18 of the last element 14 to the support rod 6, the vertical segments 19, plate 20, the spring 21.Platform 1 by wave action automatically changes its position through hole 11 for free placement of piles 8. To make the platform 1 stable position, it is provided with a ring 9 with ar on both sides of piles 8 and has two side panels and a Central hole 12, which is intended for the passage of water, and two lateral accommodate rod bearings 6, which at the top is fixed on the shaft of the multiplier 2, and the bottom are connected by pairs of horizontal beams 13. The ribs 5 are designed as separate elements 14 of the four plates 15 (Fig. 2), while the last element 14 by the connection 18 is attached to the support rod 6. The number of elements 14 depends on the depth, the strength of the sea in this area. Plate 15 pairs located one above the other and movably attached to the horizontal rod 17. The top plate 15 of one row and the bottom of another are attached in front of the vertical rods 16, and the other two are inside, when this occurs alternately raising and lowering the plates 15 at high tide and low tide, having an open plate wave hits closed, which accelerates the movement of the pontoons of 4.7. With significant depth and power of the wave rod bearings 6 can not withstand the differential pressure at the surface and at depth, it is therefore advisable to use an additional plate 20, attached to a horizontal bar 13 by means of vertical segments 19. Plates 20 are connected and hinged by means of springs 21, secured to the adjacent plates. When is this way.During the rolling of the pontoons 4,7, rod bearings 6 shaft multiplier 2 moves into and through the transmission system (Fig. 1 not shown) drives the shaft of the generator 3. While the pontoons 4,7 sway, the generator 3 to produce an electric current. The installation is influenced by the design of the pontoons of 4.7, which takes into account the changing strength of the wave is greatest at the surface and prior to its attenuation and depth, and when the sea is rough, the unit will operate. When the prevailing wind, the design is more alleghany, underwater part is shortened and contains a small number of elements 14 and plate 15 are closed, if there are plates 20, it is compressed, all the underwater part of pontoons 4,7 represents only an additional burden. If in the sea dominates the excitement and depth of the wave is significant, it increases the number of items 14 through the fixing plates 15 front and rear vertical rods 16, they in turn take the shock waves during high tide and low tide. The amplitude scale of the pontoons to 4.7 per rod bearings 6 increases due to their movement to the horizontal beams 13 and stretching of plates 20, when the wave overcomes the resistance of spring 21. So about stiny 20.The efficiency of the plant increases due to the use of force waves from base to crest, and inclined, as with the introduction of rod bearings 6, elements 14, plate 20 increases the amplitude of the sweep, which allows you to use deep wave force.The unit can be installed on small coastal Islands, with significant depth of the sea in the oil fields in the open sea, to use for heating, lighting, coastal homes, towns, cities, as well as for power transmission at a distance. For the construction does not require a large capital expenditure, and the cascade of such wave energy facilities in the coastal zone or in the open sea is an alternative to nuclear energy and hydropower, as it is environmentally friendly.
