The invention relates to power engineering, in particular to non-traditional sources of energy, and can be used for charging batteries and supplying power to various electrical loads.Known wave power installation comprising a fixed bottom basin rack, associated with the vertical reciprocating movement of the float chamber, the generator and the Converter of the translational movement of the float chamber into a rotary movement of the shaft of the generator.Also known wave power plant  considered the prototype of the present invention containing fixed on the bottom basin rack, associated with the possibility of reciprocating movement of the float chamber, a generator with a stator cores and the rotor winding and the housing is mounted on the float chamber, a ball screw Converter, the screw of which is connected with the stand, and the nut is rigidly connected with the rotor core.The known device, having a reasonable size / weight parameters, characterized by insufficiently high specific energy indicators, as well as the low quality of the generated voltage due to the instability of its magnitude and frequency.The aim of the invention is to improve the specific energy performance while improving the quality of the generated voltage wave power plant.The objective is achieved by the fact that the well-known wave power installation is about moving the float chamber, the generator with the cores of the stator and rotor winding and the housing is mounted on the float chamber, a ball screw Converter, the screw of which is connected with the stand, and the nut is connected with the core of the rotor, equipped with two overrunning clutches and ball screw Converter extra nut associated with the stator core, the latter is installed with a gap in the housing, and the winding of the generator rigidly mounted on the housing, the cores of the stator and rotor rigidly articulated by overrunning and nuts to ensure rotation in opposite directions.The analysis of the known solutions by the applicant revealed that this set of distinctive features, as the separation gap of the stator core from the housing, the rigid connection of the winding to the generator housing, the execution erikoistuvia Converter with two nuts, hard articulation through overrunning with the cores of the stator and rotor, ensuring their rotation in opposite directions, is unknown.Thus, the proposed solution meets the criterion of "Significant differences".The drawing shows the proposed wave energy installation is oyku 1, connected to the screw 2 erikoistuvia Converter translational motion into rotational, the float chamber 3, which is fixed to the housing 4 of the generator. Ring winding 5 of the generator is rigidly fixed in the housing 4 of the generator. Screw 2 erikoistuvia Converter provided with nuts 6 and 7 are rigidly connected by means of overrunning clutches 8 and 9 with the cores of the stator 10 and rotor 11. The core 11 of the rotor equipped with permanent magnets 12, the stator core is made with plusnine ledges 13. The stator core 10 is separated from the housing 4 by a gap 14.The device operates as follows.Wave fluctuations of water level cause periodic fluctuations in Poplavko camera 3 relative to the stand 1, is fixed on the bottom of the reservoir. Electricity generation is due to the energy of the wave during its ascent (first half-period of oscillations) and due to the potential energy of the float chamber 3 is placed on the generator when lowering the wave (the second half-period of oscillations).Periodic oscillations of the float chamber 3 is installed on the generator relative to the screw 2, the articulated with the stand 1, lead to a synchronous periodic rotation of the nuts 6 and 7 in agnula translational motion rigidly articulated through self-directed (overrunning) couplings 8 and 9 with the cores of the stator 10 and rotor 11, the periodic rotation of the above-mentioned nuts cause rotation of the cores 10 and 11. Considering the fact that the overrunning clutch 8 and 9 transmit torque in opposite directions, the cores of the stator and rotor will rotate steadily in one direction, but opposite relative to each other. When this clutch 8 transmits torque on the stator cores 10 only for one (active for coupling 8) half period (for example, when lifting waves). The second (passive for coupling 8) half period (for example, when lowering the waves), the clutch 8 is in the idle mode and the stator core 10 continues to rotate in the same direction by inertia. The clutch 9 is set so that transfers torque to the core 11 of the rotor only during the second (active for coupling 9) half of the period (when lowering the waves). When lifting wave, when the nut 6 starts to rotate in the opposite direction, the clutch 9 is in idle mode (passive half of a coupling 9) and the core 11 of the rotor continues to rotate in the same direction due to inertia.Thus, the cores of the stator 10 and rotor 11 rotate in opposite directions, and their active and passive half-periods alternate.Present epolamine axially oriented - EN permanent magnets 12 as poles and a stator core with axial protrusions 13. Unipolar magnetic flux generated by the permanent magnets of the rotor is closed along the path that is specified on the drawing, covering an annular winding 5 of the generator (circuit of magnetic flux through the screw 2 is removed by a magnetic decoupling of the internal parts of the rotor and stator, for example, by executing the screw 2 of non-magnetic material). During rotation of the rotor relative to the stator conductivity path circuit of the magnetic flux varies periodically from a maximum value (when the pole of the rotor is opposite the poles of the stator) to the minimum value (when the pole of the rotor is against depression interpolar space of the stator). Effects of periodic change of magnetic conduction path circuit flow is a periodic change in the value unipolar flux penetrating the ring winding 5, and as a result, putting in it an EMF. Value indeksirovannoj in the winding 5 EMF is proportional to the rate of change of magnetic flux , i.e. the rate of change of conductivity. As in the proposed decision, the cores of the stator and rotor rotate in opposite directions, the rate of change of magnetic conductivity, and hence the frequency of the ISM is in the winding EMF at the same weight indicators as in the known solution, and as a result, higher specific energy indicators declare wave power plant compared to the prototype.When lifting and lowering the waves nuts 6 and 7 erikoistuvia Converter translational motion in the rotational operating in the mode of acceleration, deceleration and reversing the direction of rotation. The presence of the overrunning clutches 8 and 9, vstrechnoi rotation of the cores of the stator and rotor significantly to stabilize the relative speed of rotation of the stator and rotor, and the stabilization rate is higher, the greater the inertia (mass and diameter) cores of the stator and rotor.Thus, the level and frequency of the induced voltage in the winding of the generator of the claimed wave power plant have greater stability and, as a result, more high quality than in the well-known wave energy device. The WAVE POWER installation comprising a fixed bottom basin rack, associated with the possibility of reciprocating movement of the float chamber, a generator with a stator cores and the rotor winding and the housing is mounted on floats is otora generator, characterized in that it has two overrunning clutches and ball screw Converter - extra nut associated with the stator core, the latter is installed with a gap in the housing, the rotor cores and stator rigidly articulated by overrunning and nuts to ensure rotation in opposite directions.
