The invention relates to hydropower, in particular to the wave power plants.Known wave power installation comprising a floating platform, generator and blade rotor with a vertical axis of rotation, while the platform is designed in the form of a shell with Anoprienko holes placed around the rotor at its periphery (U.S. patent N 4152895, MKI F 03 B 13/12, 1979).The disadvantage of this wave power plant is the potential energy of the wave and pulsed mode of operation, caused, as a rule, a jet rupture in the mine, the diameter of which is not regulated depending on the wave parameters. For constructive disadvantages include the difficulty of making spherical shell and ensuring its integrity, the placement of the turbine shaft, bearings and the turbine in the mine filled with water, which eliminates the possibility of inspection and maintenance.Known also design wave power plant, containing the second vertical axis of rotation, while the rotor is connected to the shaft of the generator, and its blades are made with the possibility of rotation of the rotor under the action of waves in one direction (the United Kingdom patent N 2081388, MKI F 03 B 13/12, 1982).The shortcoming of this wave power plant are constant rotary movement of the blade, which complicates the design node of rotation of the blade. The above structure of the required power consumption wave flow on rotating blades to install it in a working position. Only after the preliminary wave energy costs for the installation of the blades in working position the impact wave flow blade is useful and serves to move the impeller. Structural disadvantage is the difficulty in achieving uniform tensioning of cables, fixing of the support ring at a different length cables, and the unevenness of their elongation at variable loads that may change the effect of flow on the blade when the coincidence pulse stretching of the cable with the traffic flow when exposed to it on the blade.Closest to the technical essence and the achieved result to the proposed design of the wave power plant avsey and a rotor with a vertical axis of rotation, includes bearing and the annular bearing member with a fixed working blades.with. USSR N 1346845, MKI F 03 B 13/12, 1987, the authors C. M. Lejter, I. S. Kovalev and S. M. Kosareva).The shortcoming of this wave power plant is the inability to use energy and other vertical flow of the waves. Beneficial effects of horizontal flow produced only on the part of the blade, which is placed on its front edge to the normal flow. There is a constant occurrence hindering efforts at influence of different wave flows on the blade. To structural weaknesses include the impossibility of the concentration of wave energy flows, as well as the unreliability of the node transmitting the rotation of the rotor through the rollers to the shaft due to friction and the possibility of their slipping, as well as placement of the generator near the wave surface.An object of the invention is the improvement of the wave power plant, which provides the most complete use of the impact on the working blade vertical threads and the reflected waves, the exception of hindering efforts at influence multidirectional waves is the second result is solved by in the known device the wave power plant comprising a floating platform attached to it generators and rotor with a vertical axis of rotation, comprising a support and an annular bearing element with a fixed working blades, according to the invention, the platform performs with adjustable buoyancy in the form of a shell placed around the annular support member at its periphery and provided with a through Anoprienko holes blocked by gates, rotor support are in the form rigidly connected to the bearing element on the disc by means of rollers on a circular rail attached to the upper part of the casing, when secured to the support element of the working blades are in the form of annular grooves, convex surfaces oriented in the same direction.In addition, the shell platform operate in an open-topped cylindrical Cup with a bottom provided with vodonapolnyaemoy cavity.In addition, the valves supplying the drive with the possibility of independent overlapping end-to-end vanpraag holes and are in the form Sandor and dampers.In addition, the annular bearing member is performed in a radial spokes, the internal cavity of the torus and spokes do with filling with water.Also a supporting member connected to the support plate by farms circular operate as guide rail, a drive shaft connected with generators through a circular rack fixed to the disc and the gear wheels arranged on the shafts of the generators.In addition, the figure formed by the annular groove of the envelope and the chord has a shape symmetrical segment troughs centers lie on the axis of the torus, and their vertical chord.The features distinguishing the claimed technical solution, not identified in other similar technical solutions in the study of this and related areas of technology and, hence, provide, according to the applicant, the device according to the criterion of "novelty."Comparative analysis of the claimed device in relation to the totality of its essential features with the prototype shows that the device of the wave power plant is a new design platform in the form of an annular shell with Anoprienko holes and its placement around the rotor, the shape of the blades in the form of annular grooves, the scheme of transfer kr is the wave, as well as the presence of the shutter.Thus, the claimed device wave power plant meets the criterion of "inventive step".The execution platform in the form of a shell with adjustable buoyancy and provided overlapped Anoprienko holes allows you to secure the platform to the horizontal axis of the bearing member coincide with the average wave line with open holes. While passing through these openings wave flows of any orientation interact with working blades, creating aerodynamic forces are always directed towards the bulge of the blade. Thus the problem is solved using wave energy of any orientation with the greatest efficiency.For passing through the secondary blade is reflected waves cover the holes, opposite the entrance waves in the installation. The implementation of the blades in the form of annular grooves, convex surfaces oriented in one direction increases the area of interaction with them wave flow of any orientation and eliminates the possibility of hindering efforts. In addition, the implementation of spokes connecting the blade with the bearing elem is in the water cavity of the shaft carrying the annular element. This leads to improved uniformity of rotation of the rotor.In Fig. 1 is a cross sectional view along the axis of the wave power plant of Fig. 2 taken along 1-1 of Fig. 3, node a, Fig. 4 taken along 2-2.Wave power plant is a floating platform, the shell 1 is in an open-topped cylindrical Cup with a bottom 2, provided with a cavity 3 is made with the possibility of filling with water. The shell 1 is equipped with Anoprienko holes in the form of through slots 4 in its side walls with the formation of the sections between the slots of the uprights 5 with the supporting areas 6 in the upper part, which are the generators 7. Slot 4 is blocked by the shutters shandorov 8 and 9, the adjustable actuator 10, which are placed on the platforms 6.The rotor wave power plant includes a support made in the form of a disk 11 that is installed through the rink 12 on the circular guide in the form of rail 13, which is located on the contact pads 6 of the shell 1. The disk 11 through the farm 14 is rigidly connected to the annular bearing element 15, in the role of the rotor shaft, which is fixed to the working blade 16. An annular bearing member 15 is in the form of a hollow torus, and releasename with a hollow torus hollow radial spokes 17. The internal cavity of the torus and spokes are made with the possibility of filling with water.The drive shaft 11 is connected to electrical generators 7 by a circular toothed rack 18 secured to the disk 11, and the gear wheels 19 are placed on the shafts of the generators 7.The work setting is as follows.Platform with closed shutters shandorov 8 and 9 afloat transported to the installation site. When filled with water cavity 3 in the bottom 2 of the platform it is installed on the ground or close to the anchors so that the horizontal axis of the annular support member 15 coincide with the average wave line with open sandorf 8 and valve 9 by the movement of the waves. With the passage of the wave through Anoprienko hole slots 4 wave currents interact with working blades 16 so that with any direction of the wave flows flow round of 16 blades, creating an aerodynamic force directed towards the bulge of the blade, resulting in movement of the bearing member 15, in the role of a rotor shaft of a power plant. Through the forms of motion of the shaft 14 is transmitted to the disc 11, which by means of roller 12 is moving on krugopolyarizovannogo 7.To increase the weight of the rotor cavity of the shaft carrying the annular element 15 and spokes 17 connecting it with the blades 16, is filled with water. This allows you to use the weight increase as a flywheel to improve the uniformity of rotation of the rotor.With the passage of the wave through the installation of the opposite wave input gates can be closed, which allows you to have a second reflected wave to pass through the blades 16 of the rotor shaft. 1.
