The invention relates to a hydroelectric power and can b nographics buoys, and the marine yachts for recharging batteries.

Known wave power plant.St. USSR N 1596125, CL F 03 B 13/12, 1987). The apparatus comprises a stationary support, and a float connected to the Converter using a closed cable loops, pulleys, two cable drums mounted on a horizontal shaft, with the possibility of unilateral rotation. One of the pulleys made spring. When the excitement of the float moves the loop, resulting in a rotation with the help of pulleys and drums horizontal shaft, which is installed with the possibility of unilateral rotation and kinematically connected with the Converter. This wave installation is fixed and set on the shore of a sea or ocean.

The disadvantages of this setup are: fundamental need to have a rigid support connected with the ground, the complexity and bulkiness of the mechanism of transformation, which does not allow to use it as a similar item in the source of energy in Oceanographic and navigational buoys.

It is also known a device for wave energy.St. USSR N 1100418, F 03 B 13/12, 1983). The device comprises a floating body located therein TNA is Onen body and ratchet. The inertial body in the form of goods with elastic suspension, mounted on the frame, is connected with the output shaft and is in contact with the guide frame. Consequently, the inertial body has a vertical reciprocating motion.

This device for the intended purpose and essential features closest to the claimed invention and is a prototype.

The disadvantages of this device include low reliability and durability, the design complexity due to the presence of ratcheting mechanism with the wheel dogs and two crank mechanism for the kinematic connection of the output shaft and the inertia of the body.

The basis of the invention positions the task of creating a wave power plant with a more simple, reliable and durable scheme of mechanical energy Converter for navigation and Oceanographic buoys, which would ensure uninterrupted power supply of consumers as the sea, and in the absence of agitation.

The technical problem is solved by the fact that the wave energy installation comprising a floating hull and located mcindoe body in the form of goods, with elastic suspension, mounted on frame in contact with the vertical guides and the alternator, the elastic suspension is supplied installed on the upper part of the frame blocks covering their flexible shaft, whereby the inertial body is connected with the elastic suspension elements, himself elastic element is fixed on the base frame, is installed in parallel vertical guides from the side opposite to their contact with the inertial body, the shaft of the alternator is kinematically connected with the shaft of one of the blocks, and installation is further provided with a battery, a transformer with a variable transformation ratio, diode rectifier, regulator, a load device and a device to change the transformation ratio, the battery connected to the alternator through a diode rectifier and a transformer with a variable transformation ratio, the controller is connected to the output of the alternator and the battery, and the load device and the device to change the transformation ratio is connected to the controller.

At the end of the elastic suspension element from its connection with the inertial body, the DOP is it part of the frame.

The execution of an elastic suspension as mounted on the upper part of the frame blocks covering their flexible shaft, whereby the inertial body is connected with the elastic element; securing the elastic element on the base frame; setting the elastic element in parallel vertical guides of the frame from the side opposite to their contact with the inertial body; the kinematic connection of the shaft of the AC generator to the shaft of one of the blocks that are installed on the upper part of the frame was considerably simplified scheme of mechanical energy Converter for navigation and Oceanographic buoys, to improve the working conditions of the Converter, to increase its reliability and durability, because the transducer is excluded items such as a ratchet mechanism and a two-tier crank mechanism for the kinematic connection of the output shaft and the inertial body. Wave power plant equipped with an additional battery, a transformer with a variable transformation ratio, diode rectifier, regulator, a load device and a device to change the transformation ratio, and a battery connected to the alternator through the other diode AC and battery, and the load device and the device to change the transformation ratio of the connected controller is enabled to adapt the installation to the intensity of the wave at the expense of matching the generator to the load with the least loss due to the fact that the voltage regulation is done using a transformer with a variable transformation ratio, to store energy, to protect the generator from overload under strong excitement.

It is this set of essential features have allowed us to achieve a technical result specified in the task that had to be addressed, namely: create a simple durable reliable wave energy installation to provide power to the electrical equipment of the buoys, as the sea, and in the absence of agitation.

In addition, at the end of the elastic suspension element from its connection with the inertial body, additionally equipped with the movable block envelope with its flexible shaft, the free end of which is attached to the upper part of the frame. This has greatly reduced dimensions as the energy Converter and the unit as a whole.

Based on the above can secluding-effect relationship with achievable technical result, i.e. thanks to this combination of essential features created a wave power plant, which provides electricity to Oceanographic and navigational buoys not only when there is enough excitement, but when its insignificant size. In addition, it is structurally simpler, more reliable and durable.

The figure schematically depicts a wave power plant.

Wave power plant comprises a floating body (not shown), which has bearing in the form of a frame 1 with vertical guides 2, a mechanical transducer that includes an inertial body 3 in the form of goods with elastic suspension. Elastic suspension is supplied installed on the upper part 4 of the frame 1 by two sets of 5 with covering their flexible shaft 6, whereby the inertial body 3 is connected with the elastic element (e.g. a spring) 7 charms. Himself elastic element 7 with one end fixed on the base 8 of the frame 1 and is installed parallel to the vertical guide rails 2 of the frame 1 from the side opposite to their contact with the inertial body 3. At the end of the elastic element 7 from the side of the flexible rod 6 has a movable block 9, which is covered by a flexible shaft 6, freedoms the upper part 4 of the frame 1 from the inner side of the counter installed additional elastic elements 10 (for example, springs). One of the blocks 5 is kinematically connected to an AC generator 11. The installation also includes a transformer 12, a diode rectifier 13, a battery 14, a controller 15 and a load device 16 with the contacts 17. The battery 14 is connected to the generator 11 through a diode rectifier 13 and the transformer 12 with a variable transformation ratio, and the controller 15 is connected to the output of the generator 11 and the battery 14. The load device 16 and the device changes the ratio is connected to the controller 15 through the contacts 17.

Because the installation converts the vertical oscillations of the waves, the elastic element 7 is fixed to a force equal to the force of gravity of the inertial body 3. The stroke of the inertial body 3 and the stroke of the elastic element 7 is limited, and the course of the last set in two times less than the stroke of the inertial body 3. The maximum displacement of the inertial body 3 is limited by the elastic elements 10. In addition, the installation is adapted to the intensity of the wave through the use of a transformer with a variable transformation ratio.

Wave power plant works as follows. Vertical oscillations of the floating body under the action of body 3 down it pulls the flexible rod 6 and stretches the elastic element 7, while the flexible rod 6, rotating the blocks 5, causes the rotation of the generator shaft 11.

When lifting the inertial body 3 of the elastic element 7 is compressed and pulls the flexible rod 6, which is rotating blocks 5, causes the rotation of the generator shaft 11. The elastic element 7 provides a constant tension of the flexible rod 6. As the applied alternating current generator, the direction of rotation of the generator does not matter and has no impact on the operation of devices connected to it.

Voltage regulation is accomplished using a transformer 12 with a variable transformation ratio, thereby ensuring the coordination of generator 11 with the load with the least losses. After the generator 11 will develop a voltage greater than the voltage of the battery 14 begins the process of accumulation of energy in the battery 14. Until the battery 14 is fully charged, the controller 15 according to the intensity of the vibrations of the inertial body 3 is set to such a ratio that provides the maximum removal of energy. After a full charge of battery 14 is connected through the contacts 17 of the load device 16 (e.g., resistor), which loads the generator 11. Etecsa and the generator 11 is not overloaded.

In the absence of excitement electricity buoys directly from the battery 14.
