The invention relates to the field of devices wave generators in power">A known design of a wave power plant /see patent UK N 2225811 ensuring the transformation of the vibrational motion of sea waves into mechanical and mechanical for pump or electric generator.The main significant disadvantage of known construction is low utilization of the energy of the sea waves /50%/, so as not converted into electrical energy kinetic component from the total energy of a plane wave. In addition, the known design has a small geometrical dimensions and power, tied to the shore and uses energy only partially weakened coastal waves.There are other designs that converts the energy of moving waves, for example, in the energy of compressed air into the cylinder, which drives the turbine wheel /testing models of power plants underway in Japan, England, USA and other countries.However, the closest taken by the applicant for the prototype of the proposed technical solution is the above-mentioned similar, where as in the inventive energy of moving waves is first converted into mechanical, and the latest in electric,
The purpose of the invention is the improvement postavljena goal is achieved in the invention by converting the two types of wave energy: potential, depending on the deviation of the water particles in a wave from the equilibrium position /level of the calm sea/ and kinetic representing the energy of the orbital motion of water particles.The conversion of these two types of energy into mechanical energy, and the last - in power is due to the swivel mounting in the bow of the front floating sections turning from the rolling waves of closures with balances, ensuring their return stroke, separated from each other by partitions. Each shutter is pivotally connected with the connecting rods are pivotally connected with rods made on their opposite sides in the form of rods with a leading gears on the axles, transmitting the rotation through the overrunning clutch to the gearbox and generator.In addition, this objective is achieved by ensuring that each section has a hinged rod, provided at one end of the sliding bearings, sliding in guides mounted on Board opposite section, the other ends of connecting rods pivotally connected with the axle, rigidly mounted on Board another section parallel to the first.Floating sections provided with a drop in water swivel shields.The above set when the R essential features independently affect the decision delivered by the invention of the task.The above set of essential features new and not known from the practice of using the energy installations of the same type, or of the patent and technical literature.

in Fig. 6 shows part of the drive mechanism of the generator - the rod, the rod is made on the opposite the Eden top view of the drive mechanism of the generator;
in Fig. 8 shows views of the Board the floating section of the rod, the slider and the guide hinge.Wave power plant consists of a series of floating sections 1, 2, 3, 5 are connected by hinges 4 with horizontal axes. In turn, these sections are installed parallel to each other, are connected on the sides interconnected by means of connecting rods and crossheads 6, located at a specified distance on the Board from each other.In the anterior part of the nasal partition 1 on the hinges 7 installed butterfly valve 8, is divided into the plan from each other by partitions 9. Each shutter is pivotally connected with the connecting rod 10, which is in turn pivotally connected to a rod 11, is made on the opposite side in the form of slats 12.Top slats installed on their axes gear 13 connected to the overrunning clutch 15 of the roller type.In turn, the clutch 15 is connected with the gear 17, while the overrunning clutch 16 of the mechanism of transformation of potential energy of the waves - with the gear 18.In this device, the gear 17 of large diameter connected to the small gear 19 of the gearbox 20 and through the rest of the gear reducer that increases the number of turns, are connected to a generator 21 for generating current for SCSA waves is to use a vertical reciprocating movements swaying on the waves floating sections.The mechanism is driven by means of rods 23 and rod 22, pivotally fastened to each other and end gussets 24. Stocks slip on thrust bearings 25 for the transfer of the effort from the rods 23 with the vertical reciprocating motion around the hinge 4, the floating sections 1, 2, 3, 5. Enter in the additional gear 14 provides the use of wave energy on the crests and troughs, with the transmission of rotation by the overrunning clutch 15, 16, the gear 20 and the generator 21. Partitions 26 hermetically separate the front floating sections, POS.1.Side hinged connection between the sections 1, 2, 3, 5 are performed with rods 27, pivotally fastened to the hoist carriage 6, sliding in a tubular guide 28. At the other end of the connecting rod 27 pivotally connected with the axle 29, rigidly mounted on Board another section parallel to the first.Autonomous power unit /not shown on the drawing/ causes the rotation of the screw 30, is enclosed in the casing 31; the counterweight 32 on the bolt 8 is used to return it to its original position. Item 33 - stroke position of the shutter when it is fully pushed into the housing section 1 by turning the shutter 8 from the incoming waves.Drop into the water povorotnoye station with screws 30 and Autonomous power plant turns around and becomes a forward moving waves.Rolling ship waves initially hit in butterfly valves 8, which are set in motion and turn on the hinges 7 to the transfer of force on the rod 10, the rod 11, and through the slats 12 - wheel gear 13, which results in rotation of the overrunning clutch 15, the gears 20 and generators 21.Reverse gate 8 is due balances 32 with the rotation of the paddles in the initial position, without the stress transmission to the generator 21, which operate at this time due to the inertia armatures of the generators.During this period of operation of butterfly valves overrunning clutch 15 enables the transmission of torque in one direction only, which creates conditions for normal operation of the generator and transmission efforts mechanisms.Tempest in the sea, spreading further in parallel with the front waves, UPS and downs on their crests and troughs sections 1, 2, 3, 5, which, by means of rods 23 of the push rods 22, resulting in the movement of its opposite ends, is made in the form of rails 12, and the drive gears 13 and 14, which in turn drive the gear 20 and the generator 21.And here overrunning clutch 15 and 16 provide the PE the Oia generator.Thus during the movement of the rods 23 in the housing sections 1-3, 5 gear 14 does not transmit rotation to the gear, as its overrunning roller clutch slips and does not work.During the reverse movement of the rods are disconnected overrunning clutch 15, and the clutch 16 is turned on and transmits rotation through the gear 14 to the gear 18 and 19, resulting in a rotation of the gear 20 and the generator 21, which rotates continuously.Butterfly 8 during operation of the slide under decks floating sections 1, and under the action of the shock of moving waves of the station will begin to move in the wind.Therefore, in order to hold it in a predetermined area of the floating section is equipped with an adjustable shields 34 and Autonomous power stations with screws 30, which together reduce the drift velocity of the station, and the power unit is activated periodically and simultaneously moves the wave power plant in the desired area of the oceans and seas.Shallow station is installed at anchor.From hydrodynamic theory, it follows that both in shallow and in deep sea kinetic and potential energy per unit area of surface waves average for the period and the main wavelength , will be determined by the formula
where is the density in kg/m3, q is the acceleration of gravity m/s2h - wave height, m Should emphasize the fact that wave energy is proportional to the square of its height, i.e., for example, twice as high wave has a /in case of equality of other parameters/ four times more energy. see Yu GI Shamraev and other "Oceanology", Gidrometeoizdat. Leningrad, 1980, pp. 157-161. 182-184/.Technical and economic part.1. The supply of the wave power plant, in its front floating sections, turning from the rolling waves gates balances provides the possibility of using the kinetic energy of waves, representing the energy of the orbital motion of water particles and is equal to the average of 50% of total /full/ energy moving waves.At the same time, when the sea is at the station use and potential wave energy due to vertical reciprocating movements, swaying on the waves of the floating sections of the station are also equal and the total energy will be equal With regard to mechanical efficiencymin the drive mechanisms of the generator and the generator efficiency galso taking into account the conversion efficiencyineand the total energy at the terminals of the generators will be:
< / BR>The use of two types of energy moving waves provides a 2-fold increase of the ratio of energy use oxinin comparison with the known wave stations and 2-fold increase in power and wave power.2. The placement of the floating sections of the station, pivotally interconnected to each other and in parallel with each other with the formation of the floating vessel in the form of a disk, enables the creation station is a great power and stability, and reliability in operation.Thus, when the diameter of the floating vessel station D=300 m, wavelength = 300 m, the power generated by a station in this area moving waves will be determined by the formula
