The inventive power unit is a tower brace beam, which with the help of clip mechanism for securing paired helical energy Converter and the compensation telescopic drive mechanism, spiral energy Converter made in the form of a blade of the propeller, the blades of which have an angle of attack of 45 degrees, and the underside of the screw is attached to it buoyancy, support screw horizontally over the surface of the water. The screw coupling is connected with the expansion of the telescopic drive mechanism and through increasing gearbox - generator. On the rays of the tower are several screw converters, the energy of which the bus bar stack. 3 Il. The invention relates to the field of hydropower and can be used to generate electricity on the sea coast, offshore drilling and oil production facilities, as well as on ships, anchored, or drifting.Known projects of installations preobrazitb Masuda, the shutter Russell (see "Energy waves" British researcher David Ross, L., Gidrometeoizdat, 1981).These projects have a wide practical application is not received because of the large size, high cost, low efficiency and poor stability towards the sea.Analogs of the invention are: the proposal of France N 2233507, CL F 03 B 13/12, publ. 1975; ed. mon. USSR N 1320497, CL F 03 B 13/12, publ. 1987 bull. 24.The device according to the application N 2233507 contains a float located on the surface of the water and moving freely vertically, following the movements of the ox. With a float connected to the drive system of the generator located at a depth where the excitement does not have a great impact. This device is used, in particular, to generate electrical current of the sea.The main disadvantage of this device is that all working bodies of energy conversion, including the generator, placed at a depth in a hostile environment without the possibility of monitoring their work, and difficult to transfer the generated electricity to the consumers that are afloat in the excitement.Wave power plant ed.mon. N 1320497 containing the float when inoe movement of the shaft, including fixed on the float rod the rack and mounted on the shaft gear with overrunning clutches, interacting with the rail. The whole system is tilted to a vertical plane at an angle and mounted on a support above the surface of the water. The installation is based on the movement of the float along the surface resulting from the dynamic effects of roll waves on the float with an inclined shaft with a toothed rack. The main disadvantage of installation is that it only works from the waves, designed to float with the rod counter.As a prototype of the selected energy setting Presman C. D. ABT. mon. USSR N 1355754, CL F 03 B 13/12, publ. 1987, bull. 44. The unit is designed to generate electricity and contains two fixed bearing installed between the sectional driving wheels with rims tangential grooves. Wheel partially submerged under the water level. Waves hitting the ends of the tangential grooves, causing rotation of the impeller and the shaft of the generator.However, the installation has the following disadvantages: it can only work in one direction of wave propagation, i.e., uses only forward on the wheel, thereby reducing its KDE which may result in frequent damage to the working bodies, and it is also possible drifts of sand, gravel under the wheels installed.The technical result of the invention is to expand the scope of the installation on the coast or on large floating offshore facilities at anchor.This technical result is achieved by using a paddle floating coil of the transducer energy of sea waves with compensation telescopic drive mechanism.In Fig. 1 shows a General view of the wave power plant of Fig. 2 the profile of the screw of the inverter of Fig. 3 presents the layout of the wave energy Converter to the rays of the tower piers on the coast.The proposed power plant comprises a stationary circular streamlined support 1 with the beams 2, on which is mounted a spiral energy Converter consisting of linoleate screw 3 is attached to the hub 4 and buoyancy compensation telescopic drive mechanism comprising coupling 5, the inner shaft 6 with two pairs of rollers 7, the outer telescopic shaft 8 with longitudinal grooves 9, clip 10 with bearings, a mechanism fastening screw of the transducer to the beam Belenky drive mechanism is closed by a cover 13. Power plant includes energy space 14 located on a tower leg.Buoyancy 4 ensures that the position of the horizontal screw 3 above the water level at which the lower edge of his blade only touches the surface of the water. This condition is achieved by adjusting the lifting force of buoyancy 4 pouring or pumping water in her capacity with the installation of the entire system. The diameter of the buoyancy should not exceed half the diameter of the scope of the propeller blades.The screw 3 is connected to the inner shaft 6 compensation telescopic drive mechanism through the clutch 5. On the inner shaft 6 in the middle and upper part secured two pairs of rollers, providing vertical movement within the outer telescopic shaft 8, and the transmission of torque from the screw on the outside of the shaft 8 through its longitudinal rolling grooves 9. The lower part of the outer shaft 8 mounted in bearings in the yoke 10, which is rigidly fixed to the mounting beam 2, which is installed above the water surface at a height more than the height of lords when storm waves without their destructive action.On tower-shaped support 1 shown is Fig. 3).The proposed installation is used on floating offshore drilling, oil production facilities, and ships with a large displacement at anchor, mounting them on the ship shots and arrows. Floating screw from the side of the object the crane is lowered into the water and towed under the boom for connection to the inner shaft 6.Wave power plant works as follows. Linoleate screw 3 at a calm sea state is above the surface of the water in suspension. When waves from any direction in Fig. 1 14, the flow of the raised ridge of the first acts on the blade 1 of Fig. 2B, located closer to the wave and due to its configuration and angle of attack at 45othe blade 1 begins to unfold right. When the wave reaches the center of the jet stream of water begins to act immediately on two blades, right 2 and left 4. The blade 2 at this point is to flow across the concavity inside and will have the maximum impact of the waves, creating torque. At the same time, the blade 4 is to flow across, but streamlined convex side to him and according to hydrodynamics at accelerated flow around the blades reduced pressure, and the trail is and its the top of Fig. 1, the point a at a height of +, but only with a slight delay associated with the presence of sostavlyajushie pressure vector, obtained on the blades. After the passage of the wave crest through the center of the screw 3 begins to descend to the point b on the magnitude of wave height and wave, reaching the blade 3 will cause it torque is directed to the left. And as soon as the crest of a wave will come down with the blade 3, as at that time already come to the blades 1 following the crest of another wave.This creates a rotational movement of the screw 3. The magnitude of the power of energy extraction will depend on the area of the blades of the screw and wave parameters.The force of the screw 3 through the inner shaft 6, its rollers 7 and the grooves 9 of the outer shaft 8 is transmitted to the outer shaft, and with it through the gears 11, 12 on the generator.In addition, the inner shaft 6 compensating telescopic drive mechanism, as the expansion joint vertical movement of the screw 3 with buoyancy 4 during their ascent and lowering when the sea is rough, constantly provides for the transfer of torque from the screw to the generator without disturbing their kinematic relations, and also relieves lateral loads during the storm, making the installation more survivability. Vanourny with PTO drive mechanism by means of the coupling, characterized in that the support is provided with a beam with the yoke mechanism mounting of bearings, and the energy Converter of the waves made in the form of buoyancy installed it horizontally propeller, the blades of which are arranged at an angle of 45oto the surface of the water, and drive mechanism in the form of fixed bearing telescopic shaft with longitudinal grooves and the inner Central hole to accommodate the output shaft, the latter being provided with two bearings of the rollers are placed in the longitudinal grooves.
