"energy Converter wind and waves", patent of Russian Federation №2254494 from 10.09.2003, F03D 5/04), which contains associated with levers rotating platform. On each platform is installed in the blade. The power Converter also includes a kinematically associated transducer movement and site orientation and fixing the position of the blades interacting with the vane.

The inverter movement through a multiplier connected to the generator.

The disadvantages of the energy Converter can be attributed to the complexity of the design and the impossibility of its application on land.

Also known energy Converter wave (Aliyev A.S., Aliev R.A., "the energy Converter wave", patent of Russian Federation №2300663 from 22.11.2005,, F03B13/12), may be specified as the closest analogue of the invention (prototype).

The prototype contains kinematically associated rack, float chamber, a frame, a shaft, a multiplier and a generator. In addition, the Converter further comprises communicating the second shaft, the first and second gear and at least two converters movement.

The disadvantage of the prototype, you can specify the structural complexity of the transducer movement and the impossibility of its application on land to convert potential energy vehicles.

The technical problem is to simplify the design of the energy Converter and the creation of the energy Converter wind, flowing rivers and waves into electrical or mechanical energy.

This technical problem is solved by creating a fundamentally new design of the power Converter, which contains kinematically associated rack, platform, weather vane, flat blade and shaft interacting with the multiplier and the generator, as well as interaction of the plans to each other of the first and second nodes change the orientation and fixing the position of the blades, rod installed on two sides, with the possibility of rotation of the rings, pivotally connected to the root tips of the first and second rods connected peripheral terminals with first and second radial arms connected respectively with the first and second overrunning clutches mounted on the shaft. The bar is installed on the platform with the possibility of fluctuations in 90° of free rotation around its own axis, and at the ends of the rod still installed first and the second flat of the blade, the plane of which is perpendicular. Clutch couplings with radial arms and the interaction of the first and second nodes change the orientation and fixing the position of the blades with the respective stops happening on the queue.

While the first and second nodes change the orientation and fixing the position of the blades installed symmetrically from the axis of oscillation of the rod and each of them contains interacting with each other ring retainer, spring twist, a third overrunning clutch and a spring-loaded z-shaped clamp, the tip interacts with two diametrically opposite holes in the ring retainer fixedly mounted on the rod. The hub of the third overrunning clutch mounted on the rod with the possibility of free rotation, and the holder is still connected with the star, Motorauthority with a matching chain, mounted on the platform and made in the form of a segment of a circle of 90°.

The first version of the Converter contains rotating about a vertical rack 1 platform 2. Installed at the platform bar 4 in the form of a pipe with the possibility of the awn of free rotation around its own axis. The platform is still connected to the lever 5 of the vane 6, which is oriented perpendicular to the rod. The second end of the lever 5 is connected with a flat vertical vane 6. The change in the wind direction leads to a change in orientation of the platform. The rod 4 is installed on the rotary sleeve 3 rotation with the possibility of oscillations in the vertical plane at an angle of +45°. On both sides of the sleeve 3 on the rod 4 is installed movable ring 7, 8 with the possibility of relative rotation. To prevent relative longitudinal movement of the rings 7, 8 on the rod established the stationary ring 9. Movable ring pivotally connected with the root ends of the respective rods 12, 13. Peripheral tips of rods 12 and 13 is also pivotally connected to the outer ends of the first 14 and second 15 radial levers respectively. The root tips of the first and second radial arms 14, 15 still connected with the sleeves of the respective overrunning clutches 16, 25.

At the ends of the rod 4 is fixed to the first 23 and second 24 flat blades are oriented mutually perpendicular. When the first blade is oriented along the direction of the wind, the second is oriented perpendicular to the wind, and Vice versa.

The oscillation of the rod under the influence of wind leads to the oscillation of the connecting rod and associated radial levers in the vertical plane.

To change the orientation of the blades are the first 10 and second 11 nodes change the orientation and fixing the position of the blades (see figure 1, 3)

On the vertical platform 2 has a first spring stop 20. At the end points of the deflection rod 4 nodes change the orientation and fixing the position of the blades 10, 11 communicate with the respective lugs 20, which leads to the rotation of the blades at +90°. Then the bar starts to swing in the opposite direction.

Figure 2 shows a view of A-a in figure 1. The first 16 and second 25 overrunning clutch mounted on the shaft 17 so that when the oscillations of a rod in one or the other side they were in the grip of the queue.

The rise of the first rod up leads to a rotation of the first radial arm 14 and its associated first overrunning clutch 16 in a clockwise direction. The holder of this coupling is coupling with the hub, which causes rotation of the shaft in a clockwise direction.

The second clutch 25 at this point in time is outside of the clutch. The second connecting rod 13 idle goes down. During the reverse movement of the bar rises up the second rod. Now in the grip includes a second overrunning clutch 25. The moment generated by the second radial arm 15 on the shaft, is also positive, which causes the shaft to rotate in the same direction - clockwise.

The moment the vertical pressure force Ro shaft 48 Rav is n Po·cosa, where a is the angle between the rod 43 and a radial arm 45.

Summing the moments in between-π/4 to +π/4, i.e. in the range of 90° will receive:

the average time is:

The average time for one period is equal to 2·0,9PoR=1.8V PoR. For the prototype when the summation of the torques in the range of-P/2 to P/2, i.e. in the range 180° to get the average value.

Thus, the average value of the moment when the oscillation of the lever within ±45° for the period increased compared to the normal rotation of the blade in a circle 1.8 PoR/0,6 PoR=3 times.

The principle of operation of the node changes the orientation and fixing the position of the blades, the design of which is presented in figure 3, is as follows.

The power Converter includes the first 10 and second 11 nodes change the orientation and fixing the position of the blades. Each node contains the overrunning clutch 16(25), the hub which rotates freely on the rod and connected with one end of a spring twist 34. On the race overrunning clutch still installed star 33. When the boom oscillation within ±45° of the star interacts with the segment circuit 21 (22)mounted on the platform 2, the segment of a circle within 90°. The other end of the spring twist still include the barbell. When the oscillation of the rod within 90° in the interaction of stars with 3 chain spring is twisted clockwise by 90°. The tip of the pawl 39, which is one of the diametrically opposed holes in the rod that holds the fixed position of the rod relative to the Central sleeve 36. The tip of the second spring retainer slides over the surface of the ring 35 and secures the rotational position after 180°, i.e. after two 90°rotation.

The second node changes orientation and fixing the position of the blades 11 is similar to the first 10. Twist the spring in two nodes occurs at a time, because the overrunning clutch included in grip in turns. Moreover, the twisting of the springs in both nodes occurs in one direction - clockwise. Fixing holes in the ring 35 in the second node offset diametrically opposite locking holes in the first ring node 90°. The tabs of the first and second nodes in turn interact with the spring loaded stop 20. When the interaction of the pawl with the stop lug of the latch out of the holes in the ring 35, which leads to rotation of the rod attached to it by the blade around its axis and the change in orientation of the blades at ±90°. After this begins the process of reverse oscillation of the rod at -90°. Rod ranges from 90°, where the one moment on the shaft 0,9RPo.

Rotation of the shaft 17 is transmitted to the multiplier 26, which increases the speed to the nominal speed of rotation of the hydraulic pump 27. A hydraulic pump connected to the hydraulic motor 28. By excessive grazing pressure is synchronized with rotation of the motor 28. The hydraulic motor causes the rotation of the generator 29. Electrical energy can be used directly in the home or accumulated. Synchronization of rotation of the generator is possible through the synchronization of the frequency of oscillation of the rod. This requires that the position lock blades worked from the electromagnet, which is triggered from a pulse with a constant frequency of a given electronic synchronizer. This occurs after the interaction of the nodes change the orientation of the blades with emphasis. To soften the shock when the boom oscillation stop 20 should be spring loaded. On the same shaft 17 can be installed in parallel N-e number of parallel converters movement to the intended design. Thus, the operation for synchronization must be shifted in phase by 2 π/n Additional synchronization can be achieved, if the output shaft to install the flywheel.

The same transducer can be used under water. In this case, there is no need in the vane. Rod due to lobatse in the horizontal plane. The design should be installed on the pontoons to provide her with positive buoyancy. When this shaft and kinematically associated with the multiplier, the hydraulic pump and the hydraulic motor and the generator must be in surface position.

The total capacity of the energy Converter will depend on the capacity of a single module (figure 1 and figure 2), and the number of parallel modules.

The mechanical energy from the shaft torque can be transmitted from the multiplier directly to the generator or pump. Adjusting the rotation speed of the generator can be implemented by changing the effective area of the blades depending on the wind speed or the flow of the river. To do this, simply change the orientation of the blades relative to the plane of oscillation of the rod.

The principle of operation of the second variant of the energy Converter, which can be used as a wave power plant, the design of which is presented in figure 4, is as follows.

The second variant of the energy Converter is designed to convert potential energy of the waves into electrical energy. The Converter can be installed on vertical posts 50 or directly on the sea. All the mechanisms of the energy Converter mounted on a horizontal square is forme 49, fixed on the racks 50 or on the beams associated with the land or with oil platforms.

The power lever 41 with one end still connected to the pontoon 56 and the other end flat hinge is connected with a rack 50 or directly with the Bank protection wall.

The power Converter determines the length of the power lever, the volume and weight of the pontoon. To align the moments produced on the shaft 48 when the raising and lowering of the pontoon on the waves, it is necessary that the pontoon is submerged in the water under its own weight by half its volume.

The power lever varies only in the vertical plane. This is a flat hinge 42. In addition, to limit the transverse oscillation of the lever 41 can be installed vertical racks or rails with its two sides.

On the shaft 48 are still the first hub 47 and 51 second overrunning. Clip these couplings still associated with the first 45 and second 46 radial levers respectively. The tips of the radial levers 45 and 46 pivotally connected with the upper ends of the first 43 and second 44 connecting rods, respectively. Root tips of these rods pivotally connected with the power lever 41. The ratio of the distance between the hinge connections of rods and hinge 42(g) relative to the entire length of the power lever 41(R) determines when the rotation is Oia on the second shaft 48

Overrunning clutch 47 and 51 mounted on the second shaft 48 so that they were in the grip in turns. The first and second connecting rods 43 and 44, pivotally connected with the respective radial arms 45 and 46 operate in the active mode in turn. When lifting pontoon 56 first radial arm associated with the yoke fifth overrunning clutch 51, causes the rotation of the second shaft 48 in a clockwise direction. When lowering the pontoon force on the shaft is transmitted through the second connecting rod 44, the radial arm 46 and the overrunning clutch 47. When the direction of rotation of the shaft continues clockwise.

Figure 5 presents the view In figure 4 on the design of the second version of the energy Converter. The yoke of the second overrunning clutch 51 is still connected with the first radial arm 45. The radial connection of the levers 45 and 46 with clips overrunning 51 and 47 is from diametrically opposite sides of the shaft 48. Under the sequential occurrence of the overrunning clutch 51 and 47 connecting the radial arms with their clips also provides a constant direction of rotation of the output shaft 48. The rotation of the output shaft through the multiplier 52 is transmitted to the hydraulic pump 53. The multiplier increases the shaft speed to the nominal speed of rotation of the hydraulic pump.

On one shaft can transmit the rotation of the N-e number of converters e is ergie in figure 4, which includes positions 47-51. However torques energy converters are summed. The excess pressure of the hydraulic pump 53 travelways that allows you to synchronize the rotation speed of the motor 54 connected to the hydraulic pump. The hydraulic motor causes the rotation of the generator 55. Produced electrical energy can be used directly in the home or accumulated. A promising direction is the production of hydrogen by electrolysis as an alternative fuel for internal combustion engines.
