The principles of operation of the first variant of the wave energy device, the design of which is presented in figure 1 and 2 is as follows.

The wave energy device is installed directly on the beach or at some distance from the coast. Depending on the power output it can be stretched along the coast for tens to hundreds of meters. Vertical racks 1 concrete in the bottom of the sea at a distance of several meters from the coast and particularly the m distance from each other.

Through vertical racks miss horizontally first 4 and second 5 shafts with the possibility of free rotation. Horizontal shafts 6, 7 of an adjacent parcel, angled, are connected to each other through the drive connection. Such a connection shaft allows by their capacity to around coastal barriers, to increase the total capacity on the ground (output) shaft 4 and at the same time to increase the synchronicity of its rotation.

On the first 4 and second 5 shafts still installed first 10 and second 11 gears, which are coupling with each other. Instead of the gears 10, 11 on the shafts can be installed first and the second star, kinetically connected to each other by a chain. End chain connectivity (figure not shown) has the form of a figure eight. Chain link causes rotation of the shafts 4, 5 in mutually opposite directions. Replacement gears stars, chain link between them will allow you to install large distances between parallel shafts 4 and 5.

On the first shaft 4 is still installed first hub 12, thirds 14, 16 fifth and seventh 18 overrunning.

While on the second shaft 5 is also still installed hub 13 second, fourth, 15, 17 sixth and eighth 19 overrunning.

Odd overrunning clutch 12, 14, 16, 18 are installed on the first (upper) shaft that is fixed in the clutch with the sleeves of the respective clutches and re is my first rotation shaft 4 in a counterclockwise direction. At this time, the clip even clutches 13, 15, 17 and 19 are out of the clutch hub and spinning at idle. [Yuriev VI Reference designer mechanical engineer. M: engineering 1980, volume 2, str-220] However, due to the coupling of the gears 10 and 11 of the second (lower) shaft 5 rotates clockwise. Through pollperiod clip even clutches are included in the clutch hub of the respective couplings mounted on the lower shaft 5, causing it to rotate clockwise. Thus, the second shaft and mounted thereon a second gear 11 become leading. The upper shaft 4 retains its direction of rotation is counterclockwise. In this case, all odd couplings, installed on the upper shaft out of the clutch hub and do not hinder the rotation of the first shaft counterclockwise. Thus, the leading become the upper, then the lower shafts.

The holder of each clutch using a flat (odnostebelnogo) hinge 34 is connected with the upper end of the respective lever. Swivel allows you to change the angular position of the arm in the horizontal plane depending on the change direction of flow of the waves. Each pontoon (22,23) is connected with the lower ends of two parallel levers corresponding flat hinges 24. The distance between the pivot connections is equal to the distance between the two horizontal shafts is 4, 5, and therefore, the distance between the upper hinge connections of the levers 34. In case of equality of the lengths of the corresponding parallel pairs of levers 21, 30 (31, 32) pontoons 23, 33 under the influence of waves undergo vibrational motion up and down.

The weight of the pontoon is selected so that it was immersed in water for half its volume. In this case, the moments generated by the upper and lower levers on the respective shafts 4,5 when lifting and lowering the pontoon will be equal.

When lifting pontoon 23 fifth lever 30 that is associated with the yoke fifth overrunning clutch 16, results in the first (upper) shaft 4 to rotate counterclockwise. Ferrule sixth overrunning clutch 17 at this time spinning in idle.

When lowering the pontoon with the departure of the wave bottom (sixth) lever 21 enters into the sixth clutch overrunning clutch 17 and causes the rotation of the lower shaft 5 in a clockwise direction. Due to the coupling between the gears 10, 11 upper shaft 4, which became a slave, continues its counterclockwise rotation.

Similarly to the first and second shafts is transmitted torques from all pairs of levers associated with the respective pontoons. The power output shaft 4 of the wave power plant is determined by the volume and the weight of the pontoons, the lengths of the levers and the height of the waves, and also depends on the number of parallel pairs of levers (Pantone is).

To increase the total output power of the wave energy device, it is possible to subsequently enable the same type of device of figure 1 and figure 2. Thus the upper and lower shafts may be connected by cardan joints or floating jaw clutches, when the shafts adjacent pairs of coaxially to each other.

If the wave is coming from the right (see figure 2), left pontoon 33 and the levers 31, 32 under the influence of the oncoming waves oriented along the direction of its flow.

Swivel 34 allow freely set the direction of the levers 31, 32 located to the left of the uprights 1, along the direction of flow of the waves.

The pontoons are cylindrical in shape and are oriented perpendicular to the flow of the waves. This form and the orientation of the pontoons provides maximum amplitude of the oscillations on the waves, which leads to an increase in the output power of the power device.

The carrying power of the pontoon does not depend on the wave height. The length of the levers also does not change when raising and lowering. Therefore, the torques generated by the first and second shafts, do not depend on the wave height, when it exceeds the radius of the cylindrical section of the pontoon. This contributes to the synchronous rotation of the output shaft and the generator 28.

To change the orientation of the hinged levers 21, 30, etc. that are great which it stands 1, used frame orientation 29. Frame orientation is a vertical, elongated rectangular metal frame, with which the two sides of the covers with a small gap of each pair of levers 21, 30, located on the right side (see figure 2). Bracket 35 is a rectangular frame 29 is mounted stationary to the upper left arm 31 opposite pairs. However, changing the orientation of the lever 31 causes the change in the orientation opposite (right) of the levers 21, 30. Thus along the direction of wave set both the left and right levers, which ensures maximum extraction of energy from waves.

The output shaft is connected to the multiplier 25, which increases the speed of rotation of the output shaft to the nominal speed of the generator 28.

To set the multiplier and oscillator uses a horizontal platform 3, which is supported by vertical support 2. The other end of the platform welded to the nearest vertical post 1.

The output of the multiplier through the overrunning clutch 26 is connected to the shaft 28 on which is installed a massive flywheel 27. The flywheel increases the synchronicity of rotation of the generator.

If necessary, the device can be installed directly on the beach. This eliminates the need for racks 1 and left pontoons and levers in the hinge is soedineniyah 34 and the frame 29, that greatly simplifies the device.

The second variant of the wave energy device is presented in figure 3, differs from the first variant the fact that relative to the vertical uprights in pairs symmetrically on two sides are identical converters movements, each of which includes first and second ratchet wheels, the first - fourth pawl spring 38-41. Overrunning clutch mounted on the first and second shafts, replaced rapovymi wheels 36 and 37. They are installed on the shafts so as to transmit the rotation in two opposite directions. For this purpose, on the ninth to twelfth levers 42-45 installed spring-loaded dogs 38-41. Springs provide the clamping dogs to the ratchet wheels. Moreover, the clutch dogs with relevant rapovymi wheels occurs at a time. If you are lifting pontoon leading becomes the first ratchet wheel 36 (Val), when the pontoon sinking under its own weight becomes the leading second ratchet wheel 37 (shaft 5). Due to the coupling of the first and second gears 10, 11, the direction of rotation of the shaft 4, 5 is not changed. The first shaft 4 rotates counterclockwise, the second shaft 5 clockwise.

Otherwise, the principle of operation of the second variant of the energy installation coincides with the principle of operation of the first option.

The operation principle of trateg the option of wave energy devices (see 4,5) is as follows.

As in the previous embodiments, the first 4 and second 5 shafts mounted on the rack 1 with the possibility of free rotation. They also fixed the corresponding gears 10, 11 located in the clutch with each other.

Unlike previous versions on the shafts 4,5 installed the third 50 and fourth gear 51 fixed to the stationary clamps tenth 48 and eleventh 49 overrunning. Moreover, they are shifted relative to each other in the transverse direction (see figure 5). The third 50 gear is included in the coupling with the first gear rack 52, 51 and the fourth with the second gear rack 53.

The rack 52, 53 by means of the guide strips 55 and lintel 56 is installed vertically with the free walking up and down vertically. The rack 48, 49 are shifted relative to each other in the transverse direction, and the corresponding gears 50, 51.

Overrunning clutch 48 and 49 mounted on the shafts 4 and 5 so that they were in the grip in turns. This overrunning clutch provides a constant directional rotation of the shafts. While leading become the upper, then the lower shafts.

The upper ends of the vertical gear racks connected to each other by a horizontal crosspiece 56. The lower tips of the toothed rails with brackets 57 also is still connected with the fifth pontoon 54. This provides rigidity when exposed to the oncoming waves. The pontoon under its own weight and the weight of gear racks must be submerged in water to half its volume. This ensures the equality of the torques generated on the shafts 4 and 5 gears 50, 51 as when lifting and lowering the fifth pontoon.

To create more torque on the output shaft can be used kinetic energy of the oncoming waves. For this purpose, on the output shaft with overrunning clutch can be installed impeller. An impeller is mounted stationary on the holder of the overrunning clutch. Under the influence of the oncoming waves spinning impeller and transmits rotation through the overrunning clutch to the output shaft.

If necessary to increase the output power of the device can be simultaneously used all three options conversion of wave energy. This will sum the torques generated by each of the three options separately. Thus the relative time difference between the torques generated by each of the three options, allows you to increase the synchronicity of rotation of the output shaft. The application of the first and second variants of the device are identical. They differ only in the design of converters movement. The efficiency of the device is the STV increases due to the simultaneous conversion of potential and kinetic energy of the simultaneous conversion of potential and kinetic energy of the waves.

To increase the output power of the device may parallel output shafts 58 and 59 on the kinematic diagram in Fig.6. Leading bevel gears 62 and 63 are mounted on the carriers overrunning 60 and 61, the hub of which is fixedly mounted on the ends of the shafts 58, 59. The driven bevel gear 64, 65 is stationary mounted on a common shaft 66. Torques of shafts 58 and 59 are summed at the output common shaft 66. It also improves the synchronisation is common shaft, which can be retrofitted with the flywheel.

Wave energy device can be effectively used to protect coastal areas from the damaging effects of waves and at the same time to obtain an alternative electrical, mechanical and thermal energy in the coastal areas of seas and oceans.
