Wave power refers to hydropower.

Closest to the proposed device is a wave power plant containing a floating hull, mechanical energy Converter of the waves, made in the form of a horizontally installed drove, with one end connected with a vertically and pivotally mounted on the body shaft connected to the rotor of the generator, the stator of which is connected with the floating body, and the other end provided with a weight (see patent US 2010/0228401, 09.09.2010).

The downside of it is incomplete use of energy waves in a wide range of sizes. The reasons for these shortcomings are fixed size, and led. Outside the specified size of the wave number of oscillations per time interval is reduced.

The technical objective of the proposed wave power plant is expanding range optimally used waves, increasing its efficiency and power.

For the technical solution proposed wave power plant containing a floating hull, mechanical energy Converter of the waves, made in the form of a horizontally installed drove, with one end connected with a vertically and pivotally mounted on the body shaft connected to the rotor of the generator, the stator of which is connected with the floating body, and the other end provided with a weight, wherein the power plant is equipped with additional floats, connected with the housing by means of the telescopic pull-out mechanisms, with the possibility to adjust the total length of the floating part of the hull and floats, equal to the half-length of the wave, in addition, led is equipped with a telescopic pull-out mechanism for moving the mass relative to the drive shaft of the generator.

In addition, the wave power plant is supplied by a multiplier.

In addition, the wave power plant is equipped with overrunning clutch.

A distinctive feature of the proposed technical solutions from well-known is the fact that the power plant is equipped with additional floats, connected with the housing by means of the telescopic pull-out mechanisms, with the possibility to adjust the total length of the floating part of the hull and floats, equal to the half-length of the waves, and, in addition, led is equipped with a telescopic pull-out mechanism for moving the mass relative to the drive shaft of the generator.

The essence of the device of the wave power plant is illustrated by drawings, where figure 1 shows a structural diagram of a wave power station with additional floats, figure 2 is a view of it from above.

Wave power plant comprises a floating body 1, additional floats 2, include the main housing 1 with the telescopic pull-out mechanisms 3, mechanical energy Converter of the waves, including the generator 4, a horizontally mounted carrier 5, with one end connected with the vertically and pivotally mounted on the body of the shaft 6 connected with the rotor of the generator 4, the stator of which is connected with the floating body 1. The other end of the carrier 5 is provided with a mass of 7 with telescopic pull-out mechanism.

The operation of the wave power plant is as follows.

Under the action of the waves building 1, located on the flexible connection with the anchor associated with the land (not shown)oscillates.

When this happens change the angle of the axis of the shaft 6 relative to the horizontal plane associated with the earth. Unbalanced weight 7, mounted on the drive rod 5, making a circular movement about the axis of the shaft 6 causes it to rotate, rotating the armature of the generator 4.

To align with the period of the wave motion of water floating body 1 is provided with an additional floats 2 telescopic mechanisms 3 for extension relative to the floating body 1 and the telescopic mechanism for the nomination mass 7 relative to the axis of the shaft 6 (see Fig 1, 2).

Due to the change in distance from the shaft of the generator to the point of the center of mass of this point goes along different trajectories, respectively, while using a different time, that is, p is khojdenie longer trajectory requires more time this statement has an inverse relationship, for example.

When the frequency of rotation of the mass with frequency wave generation passing the trajectory of the center of mass will be the most complete, and completion of movement of the center of mass is closest in time to the next cycle, i.e. the time in which the shaft of the generator will be located in the movable state for a period of time will be the longest.

In case of mismatch of frequencies will be laying time of a full cycle to the next cycle, which will cause the center of mass will be held only a fraction of the full trajectory, and consequently a reduction in the number of revolutions of the generator for a period of time.

Conclusion: adjusting the overall length of the body with floats and the distance of the mass from the axis of the shaft 6, we increase the energy efficiency of the wave.

In addition, the supply device retractable floats creates greater stability of the device on the water.

The total length of the floating part (hull and floats) can be adjusted for a more complete conversion of wave energy. To obtain one-way rotation of the shaft 4, the device may be equipped with an additional multiplier (see patent RU 2141057 publ. 10.11.1999), freewheel (see patent RU 2152535 publ. 10.07.2000).

This embodiment of the device allows to increase the capacity of the disorder and to expand the range of optimally used waves.

Example

When the aggregate size of 4×4 m and the distance from the axis of rotation of the mass to its center of gravity 2 meters, the mass of 300 kg and the rise of one of the edges using wave on 2 meters, current with a frequency of 5 seconds, get a job for one oscillation, equal 5880 kJ, the power taken from the generator during this period, will be 1152 watts (taking into account the efficiency of the generator). Accordingly, for the hours will be made 720 fluctuations 1152 W, i.e. the power of the device will be 829,44 kW/h
