The invention relates to hydropower and can be used to convert wave energy into electrical energy.Known wave energy is the second float, the Central portion and the edges of which are connected by means of flexible elements with the body and PTO generator (see and.with. The USSR 1260557, CL F 03 13/12, 1986).The disadvantages of the known devices are relatively low efficiency of converting wave energy into electrical energy and light efficiency.Known wave power installation comprising a anchored raft, pontoon submerged under the water level device PTO, coupled with a flexible coupling with the raft (see. A. c. The USSR 1341373, CL F 03 B 13/12, 1987).A disadvantage of the known devices are limited functionality due to the fact that transformations are used almost only vertical vibrations of vzaimoprityazhenie raft or pontoon.It is also known a device for converting wave energy, containing the shaft attached to it a hollow float, partially filled with liquid or loose ballast (see and.with. The USSR 931940, CL F 03 13/12, 1982).The disadvantage of this device are also limited functionality, so as to convert is used only difference arhimedova forces on the crest of a wave in her pocket, and the process Osumi characteristics of the waves.The closest device to the same destination to the claimed invention on the totality of symptoms is the wave power installation comprising mounted in the bearings of rotation and connected to the generator shaft with a console attached to it in one perpendicular to the shaft plane and offset from each other in the circumferential direction floats (see. A. with. The USSR 1208298, CL F 03 In 13/14, 1986), adopted for the prototype.The drawbacks of the prototype is its limited functionality and relatively low efficiency. This is because the effect of converting wave energy into electrical energy is caused only by the difference arhimedova forces acting at each point in time on the adjacent floats, located respectively on the crest and in the trough of the wave. When this process is carried out only when the combination of the geometric parameters of the device and the respective characteristics of waves providing such a location adjacent floats. In addition, reverse the direction of movement of waves (for example, the case of the tides - tides) immediately violates the efficiency of the device.The invention consists in the practical energy as due to vertical oscillations of the water, and due to the inhomogeneity of the wave motion in the horizontal direction in either direction of the waves, their intensity, the combination of characteristics, etc. that is obtained by making the device unidirectional torque acting on the shaft in any combination of the above factors. Due to this the efficiency of the device according to the principle of its action is not dependent on the direction of the waves, the nature of their origin, is stored in the complete absence of waves, changing the depth of immersion of the float under the action of the tides, etc.The technical result - increased functionality of the design and increase its efficiency.This technical result in the implementation of the invention is achieved in that in the known wave energy device containing a mounted in the bearings of rotation and connected to the generator shaft PTO and two flat float located eccentric to the shaft axis and offset relative to each other in the circumferential direction, the peculiarity lies in the fact that in the setting introduced two additional shaft freely mounted in bearings rotation coaxially with the shaft OTB is mentioned coil springs with different directions of winding, each of which is tightly fitted on one end of the output shaft and the end located near an additional shaft, with the floats of a cantilever at the diametrically opposite points of the surfaces of the additional shafts with the possibility of adjusting and fixing the positions of the planes of floats.The invention is illustrated in the drawing, which schematically illustrates the wave power plant.Wave power plant comprises a set rotation in the bearings 1 and is connected to an electric generator (not shown), the shaft 2 of the PTO and two flat float 3, 4, arranged eccentric relative to the axis of the shaft 2 and are offset from each other in the circumferential direction, two additional shaft 5, 6, freely installed in the supports of rotation 7 coaxially with the shaft 2 PTO on opposite sides of the latter and the friction associated with the shaft 2 PTO with two twisted coil springs 8, 9 with different directions of winding, each of which is tightly fitted on one end of the shaft 2 of the PTO and the end located near an additional shaft 5 or 6. If this floats 3, 4 cantilever with tie rods 10, 11 with a spherical ball is overhasty additional shafts 5, 6 with the possibility of adjusting and fixing the positions of the planes floats 3, 4. The design of the spherical hinge 12, 13 with the release of well-known and therefore not disclosed in detail in the application materials.The plant is operated as follows.In the initial position thrust 10, 11 necessarily installed and fixed in the spherical joints 12, 13 parallel to each other, so the plane floats 3, 4 are oriented in parallel planes. For example, consider the case when, as shown in the drawing, rods 10, 11 are installed vertically and the plane floats 3, 4 respectively horizontal. For example, the direction of impact on the floats from the water upwards (this is absolutely not matter the direction, whether it is a wave or a rise in water level, tide, etc). When looking to the right in the drawing to the secondary shaft 6 torque from the side of the float 4 is applied counterclockwise naturally in the same direction begins to rotate the shaft 6, thus due to the force of the clutch spring 9 is twisted, increasing the tension between the secondary shaft 6 and the shaft 2 PTO, resulting in these shafts rotate as a unit. With this turn (n is the Yagami between the shaft 2 and the additional shaft 5 is attenuated. Simultaneously, the float 3 under the same influence of water also goes up, additional shaft 5 is rotated clockwise (view from the right side), due to the strength of the coupling part of the spring 8, covering the shaft 5, unwound, and the fit between the shafts 2 and 5 again, already weakened from the other side of the spring 8. As a result, the shaft 2 slips in the spring 8 in its rotation and is not dependent on additional shaft 5, the shaft 2 rotates counterclockwise when viewed from the right. Now let wave acts on the floats 3, 4 from top to bottom. The shaft 5 is rotated counterclockwise (all the time look to the right), the spring 8 is twisted, the shaft 2 to the shaft 5 rotate as a single unit. When the rotation shaft 2 spins covering part of the spring 9. Simultaneously, the float 4 goes down, turning the shaft 6 in a clockwise direction and unwinding, thereby, the spring 9. As a result, the shaft 2 slips in the spring 9 and is rotated counterclockwise. It is obvious that any orientation of floats 3, 4 in parallel planes (rods 10, 11 are parallel to each other) and with any direction of the perturbations of the water to the shaft 2 PTO is applied unidirectional torque and the shaft 2 rotates in the same direction. Takout the axis of rotation of the shafts.It is obvious that the proposed installation is extremely simple in construction, versatile and has a high efficiency. Its performance in principle does not depend on the nature of the perturbations of the water, the direction of the perturbation parameter in the wave, differential, etc., the Direction of rotation of the output shaft in principle does not depend on the direction of any perturbations of the waves. If necessary, the plane floats can be rotated perpendicular to the direction of the wave. However, these planes should be parallel to each other. The wave power installation comprising mounted in the bearings of rotation and connected to the generator shaft PTO and two flat float located eccentric to the shaft axis and offset relative to each other in the circumferential direction, characterized in that the installation introduced two additional shaft freely mounted in bearings rotation coaxially with the PTO shaft on opposite sides of the latter and the friction associated with PTO shaft using two twisted coil springs with different directions of winding, each of which is tightly fitted on one end of the output shaft and to the opposite points of the surfaces of the additional shafts with the possibility of adjusting and fixing the positions of the planes of floats.
