The invention relates to devices for converting sea wave energy into electrical energy, among which float wave electric power station.

Analogues of the claimed invention is "Generator hydrostatic wave energy WO 2012/116459 A1, 07.09.2012, F03B 13/16", in which fluctuations floats on the waves with the help of pistons pumped sea water by pipeline to the coast, where it enters the turbine with a generator; Wave power plant SU 1213239 AND 23.02.1986, F03B 13/20", in which one of the two floats connected by a hinge, is the turbine with the generator, between the floats are the bellows are compressed and stretched to accommodate the fluctuations of floats, and pumped fluid through the turbine.

The closest analogue of the claimed invention is "the Wave power plant, SU 1321902 A1, 07.07.1987, F03B 13/12", comprising a housing with a chamber filled with liquid and connected by a channel, two side float is attached to the housing and arranged symmetrically about its axis, a turbine located in the channel on one axis with the electric generator and an associated, in which the lifting and lowering of the floats on the waves of the fluid flows through the turbine from one cell to another.

The nearest analogue to install the operating position relative to the front nab the surrounding wavelengths, the device is fixed by means of anchors, wave energy is spent on the oscillatory motion of the float chambers with liquid cargo, and located on the housing of the turbine and generator, which reduces the efficiency of the installation, the pressure of the fluid in the turbine is determined by the difference of liquid levels in the chambers.

The objective of the invention is to increase the efficiency of installation and automatic orientation of the mounting with respect to the front of the rolling waves.

The objective of the invention is achieved in that the float wave electric power station, comprising a housing with a chamber filled with liquid and connected by a channel, two floats, arranged symmetrically about its axis, a turbine located in the channel on one axis with the electric generator and an associated, according to the invention, provided with a keel, stabilizing its position relative to the vertical, two side floats attached to the housing and positioned with its different sides along the axis of the housing, stabilizing the position of power relative to the front incident wave limiters movement of floats arranged on the housing, this camera is made corrugated and are located on the body symmetrical about an axis, and two floats, placed symmetrically relative to the axis of the housing, rigidly connected with the possibility of rotation around the axis and rtraline to the upper parts of the corrugated cells, the tensile and compression which ensures that the passage of fluid through the channel connecting the inside of which is the turbine.

Unlike the closest analogue in which the device is fixed by means of anchors to install the operating position, the proposed floating wave power plant to stabilize the relative position to the front of the rolling waves are two floats, which are fixed on both sides of the device and are located along the symmetry axis of the device. Under the action of hydrostatic forces and the gravity forces on these floats, the device is automatically installed parallel to the front of the rolling waves. Stabilizer position of the body offer float wave electric power station relative to the vertical is a deep keel. Symmetrically relative to the axis of the housing there are two rigidly interconnected float arranged symmetrically about the axis of the housing can be rotated around the axis and attached to the upper parts of the corrugated chambers, tensile and compression which ensures that the passage of fluid through the channel connecting the inside of which is the turbine. Corrugated chamber positioned on the housing in a horizontal plane symmetrically with respect to the axis of the device. The turbine is located between the corrugated cells is under the axis of the device and is connected to a generator. On the housing are arranged symmetrically relative to the axis of the housing limiting movement of the floats. Wave energy is expended in turn floats around the axis of the housing, the flow of fluid between the corrugated cells through the turbine. Compared with the closest analogue to the proposed float of the wave power wave power is spent on fewer moving parts, lots of floats in the proposed wave power station at approximately the same dimensions less than the mass of floats with goods and cameras with the liquid on the body of the analogue to work should oscillate, respectively, and the efficiency of the proposed float wave electric power station more than the nearest equivalent.

Float wave electric power station illustrated in Fig. 1 and Fig. 2.

In Fig. 2 shows the float wave electric power station with its inner part.

In Fig. 1 is an external view of the float of the wave power plant.

Kiel 1 stabilizes the position of the device relative to the vertical. The side floats 2, is attached to the housing 10 and located along the axis 6 of the device, stabilize the position of the device relative to the front of the oncoming waves. Symmetrically located relative to the axis 6, rigidly interconnected floats 3 can be rotated around the axis 6. The 3 floats attached to the top is the second part of the corrugated chambers 4. On the housing 10 are limiting motion 5 for 3 floats. The tensile and compression corrugated chambers 4 fluid passes between the corrugated chambers 4 through the connecting channel 7, which is located inside the turbine 8, which is located on the same axis with the electric generator 9.

Float wave electric power station operates as follows.

When the oscillations of the waves on the floats 2 are hydrostatic forces and gravity are currently floating wave power plant in parallel with the front wave movement. Large enough and deep keel 1 has a relatively large inertia due to the relatively long arm strength and a large amount of water adjacent to the keel, so the orientation of the housing 10 relative to the horizon float wave electric power station remains constant. With the passage of the wave plane, which contains the floats 3, is rotated about the axis 6, the volume of corrugated chambers 4 is changed and the working fluid passes through the channel 7, rotating the turbine 8, which rotates the generator 9. Limiting movement 5 floats prevent excessive deformation of the corrugated cells 4.

Float wave electric power station, comprising a housing with a chamber filled with liquid and connected by a channel, two float located symmetrical relative to the tion of its axis, turbine, located in the channel on one axis with the electric generator and an associated, characterized in that the power plant is equipped with a keel, stabilizing its position relative to the vertical, two side floats attached to the housing and positioned with its different sides along the axis of the housing, stabilizing the position of power relative to the front incident wave limiters movement of floats arranged on the housing, this camera performed corrugated and are located on the body symmetrical about an axis, and two floats, placed symmetrically relative to the axis of the housing, rigidly connected with the possibility of rotation around the axis and attached to the upper parts of the corrugated chambers, tensile and compression which ensures that the passage of fluid through the channel connecting the inside of which is the turbine.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines.
