The invention relates to energy and can be used to create Autonomous surface environmentally friendly sources of electrical energy, using wind energy and wind waves.Also known wave power plant /1/ above-water platform supported by four tubular hollow struts and associated with floats using swivel brackets connected through the cables to the drums of the winches, the transmitting torque generators. However, winch-rope mechanisms increase the intensity, complicate the kinematics in General and do not provide high efficiency. However, all the above-mentioned analogues additionally not contain wind installation that can compete at the power output with a wave.The task of the invention is to increase efficiency through maximum generated power from space.This object is achieved due to the fact that Volno-wind power plant comprises a surface platform, vertical tension rods, floats and arm. Each rocker inner end pivotally connected to the bottom platform and the articulator is equipped with amortizer is Oh, geared with a pinion, mounted on the outer yoke reversible overrunning clutch, an output shaft which is coupled to the inertia of the pulley and has a unidirectional rotation. Under the platform in the center of a vertically installed partially protruding above the level of the waves sealed hollow cylinder rigidly connected to the recessed ballast cargo through rod connected through the Hoop and anchor rope bottom cargo. Each float is hinged to the arm and provided with a bottom disk with protoplasm cargo, which is below the level of the waves horizontally fixed soothing plate rigidly connected with the nearest to it of the carrier rack. Above the platform is placed a call on hold to the rod wind turbine with vertically spaced axes of the two windwheels, having the opposite direction of rotation. When this bottom on the edge of the platform on each arm pinned restrictive buffer, and with shallow or inshore supporting rack can be extended, the support and marked directly on the bottom ground.The drawing shows a side view of a power plant.The power plant comprises a surface platform 1, the vertical load-bearing columns 2, 3 floats the new disks 8 zabostovki 9 and peretaplivanii cargo 10, a sealed hollow cylinder 11, the Central fixed the float 12, a rod 13, the bottom of the ballast load 14, soothing plate 15 with flaps 16, Hoop 17 is connected by a cable 18 with bottom load or anchor 19. Above-deck rod 20 is rigidly connected to housing 21 gondola dual wind turbines, with a fixed cone-shaped racks 22, 23 of the top 24 and bottom 25 of the propeller. Under the platform 1 on each of the rocker arms 4 are restrictive buffers 26, and the nodes of articulation of the rocker arm 4 with the platform 1 is equipped with shock-absorbing springs 27. The output shaft of the PTO overrunning 7 equipped with inertia pulley 28. Inside the housing 21 gondola posted by: Overdrive gearbox, the generator, the device semioriental blades to the wind and turn their planes in the "weather Vane" during the stormy wind, and also for stabilizing the speed and the power output is not shown.The power plant operates as follows.Swaying on the waves of each of the floats 3 actuates the rocker arm 4, which moves up and down the rack 5 and pinion 6 cyclically makes several turns in forward and backward directions, and the output shaft of a reversible overrunning clutch 7 imim speed PTO constant in times of change the direction of the translational motion of the rack 5 on the reverse, i.e., in its extreme upper and lower positions. Each half-submerged in water, the float 8 while rocking on the waves keeps the vertical position using the load 10, and use the disk 8 with zaborowski 9 prevents the float 3 to dive under water or fly in the air, i.e. promotes complete repetition of the amplitude of oscillation of the waves and the transfer of larger moment of force through the arm 4 on the rack 5. Because the formation of large swinging platform efforts, then, firstly, it is located under the float 3 below the waves, soothing plate 15 quite a large area dampens these cyclically changing the direction of force, and secondly, on the opposite side symmetrically is a similar site with the float 3. Because the probability of simultaneous and continuous application of oppositely directed overturning forces the maximum value is negligible, the presence of four pairs located around the platform 1 floats 3 is sufficient to ensure the greatest stability of the platform 1 from rocking.Because the maximum offset down their common centre of gravity generated by the ballast load 14, and a speaker above the waves sealed hollow cylinder 11, even constant the ü from its vertical position, moreover, the deviation within 10% for wind turbines is negligible.When a sudden squall the wind soothing plate 15 simultaneously perform the same stabilizing function. The flaps 16 prevent from "tightening" of the platform in emerging imbalance mutually compensating each other deployed forces generated by rotating at different heights in opposite directions propeller 24 and 25, which can be addressed constructively.During hurricane platform retains substantially horizontal position, because above the maximum operating wind speed, for example greater than 30 m/s, the blades of both windwheels deployed planes in the "weather vane", i.e. the flow without wind resistance. Windage round rods 20, housing 21 disc-shaped, cone-shaped racks 22 and 23 are generally small. Accordingly, by reducing the wind speed to the working values below 30 m/s all blades spontaneously restore. Preventing damage and breakage of the rocker arm 4 at very high crests of storm waves is restrictive buffers 26 and compression damping springs is undertie technical means is the Union of all generators in the overall coordinated voltage and frequency electrical circuit, as well as the way data transmission cable of generated electricity to shore offline distribution station.Sources of information taken into account:
