This source of information is a means to the same destination, which is characterized by a collection of characteristics that is closest to the essential features of the invention in the first embodiment of the wave energy device. It can be specified as the closest analogue (prototype) for the first variant of the wave power plant.

Also known wave power installation comprising a horizontal shaft, pontoons, N-th number of paralleled converters oscillatory movement of the pontoons with the l-shaped lever and generator [see US 4392060 AND (JESSLE So IVY), 05.07.1983, F03B 13/12]. This installation is a tool that is e purpose which are inherent collection of characteristics that is closest to the essential features of the invention according to the second variant of the wave energy device. It can be taken as the closest analogue (prototype) for the second variant of the wave power plant.

The disadvantage of the prototypes, you can specify their structural complexity and low efficiency.

The technical problem is to increase the efficiency of the energy Converter and to simplify its construction.

This technical problem is solved by creating a fundamentally new design of the wave power plant, which includes interacting with each other, the first and second shafts installed with the possibility of free rotation, pontoons, pairs given in parallel levers pivotally connected with the respective pontoons. It also contains first and second gear fixedly mounted on the shafts and are included in engagement with each other, N-e number of converters movements that are installed on the shafts, and a generator. Converters movements consist of first and second overrunning clutches, carriers are still connected with the upper ends of the pairs given in parallel levers, the lower ends of which are pivotally connected with the respective pontoons. The distance between the hinges is equal to the distance between the shaft and, and when the clip upper coupling each pair engages with the hub, the shroud lower clutch out of engagement, and Vice versa. The first shaft is an output and through the hydraulic pump and hydraulic motor connected to the generator.

Each transducer movement contains an additional restriction nodes of the active site of the oscillatory movement of the levers.

Each node limits the active site of the oscillatory movement of the levers consists of the overrunning clutch, comprising a plug fixedly associated with the radial actuators that interact with the appropriate delimiters, spiral springs and measured including carriers, secured across the root portions of the levers.

The site constraints of the active site of the oscillatory movement of the levers consists of upper and lower nodes of the fault levers installed in the root portion of the respective levers. They include the hinged connection of the two parts of the lever that interacts with a spring-loaded movable coupling mounted on the lever with the possibility of longitudinal displacement and communicate across the finger with the arcuate wedges that are installed with the lower and upper sides.

The second variant of the wave power plant includes a horizontal shaft, pontoons, N-th number of paralleled converters oscillatory DV is the position of the pontoons with the l-shaped lever and the generator. Thus converters oscillatory movement of the pontoons include the flange of the cylindrical form, mounted on a horizontal shaft with the possibility of free rotation and rigidly associated with the root part of the l-shaped lever. The lever interacts via a hinged associated stem with hydro - or pneumonias, the output of which through hydro or newmanator connected to the generator.

The energy Converter wave is set on the seafront on a high pedestal. Two parallel horizontal shafts 43, hinged on one vertical line, permanently installed first and the second gear 15, 11, and the hub of the first and second overrunning converters movements 3 and 4. Clip these couplings still connected with the upper ends of the first and second parallel arms 9. The lower ends of levers pivotally connected with the pontoon 10. The distance between the pivot connections is equal to the distance between the shafts 8 and 12.

The first 13 and second 14 overrunning clutch group II are installed on the shafts so that when the pontoons 25 and 26 are lowered under its own weight down to the clutch input is t the lower sleeve 13, what causes the rotation of the lower shaft clockwise. At the top of the clutch out of the clutch and spinning in idle counterclockwise while lifting pontoons under the influence of waves in the coupling includes an upper coupling 14, which causes the rotation of the upper shaft counterclockwise.

Because the first clutch 15 and the second 11 gears upper shaft 8 constantly keeps its direction of rotation. On the lower output shaft of the hydraulic pump 12 is installed. The hydraulic pump may be a rotary type (see RF Patent №2289701 from 16.06.2005, "Rotary engine").

The outputs of the hydraulic pumps of the same type energy converters can be connected in parallel to a single accumulator, connected to the hydraulic motor. The hydraulic motor causes the rotation of the generator. To synchronize the speed of rotation of the output shaft while changing the height of the waves overrunning clutch must be group II, with forks [see Viewref. Reference designer-mechanical engineer. Vol.2. M., engineering, 1980 str-216]. Fork overrunning connected with the respective levers forks 17 and 18.

Using a spiral spring 16, the fork lever 18 is pressed against the upper stopper 20.

Upper limiter sets the angle of the upper arm 18 when lifting pontoon on the shafts.

The lower limiter 19 sets the angle of the lower arm of the fork 17. Still the way set the active angle levers, which levers do not create torque on the shafts 8 and 12.

When the deflection of the lever 9 in the reverse direction (clockwise) spiral wound spring 16 returns the lever of the plug 18 and an associated plug overrunning clutch to the stop 20. Further, the clutch operates in the normal mode.

Similarly works the lower the overrunning clutch of the transducer movement. Plug the bottom of the clutch associated with the lower arm of the fork 17, communicates with the second spiral spring 16 and the stopper 19. With the arms of the forks 17, 18 communicate the first 21 and second 22 drivers enshrined in the root portion of the levers 23, 24, respectively.

When lowering the pontoon to the lower extreme position of the lower arm of the fork 17 out of the lower clutch overrunning clutch. On the lower lever 9 rotates idle and does not create a torque on the shaft 12.

Thus, the torques generated by the levers on parallel shafts 8 and 12, do not depend on the height of the waves. To improve on the output shaft can be installed massive flywheel.

Each of the levers 23 and 24 in figure 3 consists of two pivotally connected parts. The root portions of these levers still connected to the clamps of the respective overrunning clutches 13 and 14.

On each of the parts of the lever 34 and 35 rigidly fixed ring 34 and 38. Outside on churn the Pnom the connection sleeve 39 with free longitudinal movement. The clutch under the action of the cylindrical spring 42 fixes the axial position of the two parts of the lever.

The lever is not bent at the hinge connection and running at full length. The inner tip of the finger 40 moves along the groove 41 of the second link lever 35 and provides only a longitudinal movement of the locking clutch 39.

When the levers 23 and 24 are rejected before the mounted using the brackets 28 and 29 of the arcuate wedges 30, 31, the fingers 40 knots fault 32 and 33 cooperate with the arcuate wedges 30 and 31. Is offset from the corresponding movable coupling with swivel. Further lifting or lowering the pontoons 25 and 26 causes the deflection of the levers 23, 24 relative to the pivot pins. The root of the links 34 of the levers 23, 24 retain their angular position still. During the reverse course of peripheral links 35 to the specified arc wedges 30 and 31 the provisions of the levers 23 and 24 operate at full length.

The break levers in the hinge connection provides a constant torque on the shafts regardless of the height of the waves.

On the output shaft of the energy Converter can be mounted hydraulic pump 5, for example a rotary type [Aliyev A.S. and other RF Patent №2289701 from 16.06.2005, "Rotary engine"].

Then the oil under high pressure from a stand-alone parallel power converters pipes is collected in the bottom of the Central tube or in the capacity of the high pressure connects to the hydraulic motor 6. Excessive oil pressure is discharged through the valve into the tank low pressure. The hydraulic motor 6 is connected to the generator 7 to generate electricity.

In the case of the use of piston pumps energy Converter wave can be significantly simplified. In this case, the levers are mounted on the same horizontal axis with the free oscillatory movement in a vertical plane.

In the root portion of each lever with the upper and lower sides of the installed hydraulic pumps that operate in antiphase. The outputs of the pumps given in parallel and connected to one drive, which is maintained at a constant pressure.

The hydraulic motor 51 with the generator 52 is connected to hydrocopter 50 with high constant pressure. This design wave power plant is more efficient than with a mechanical drive and a multiplier.

Wave power plant can be used as an independent source of electrical energy. This setup significantly reduces the destructive effects of waves on the shore.
