Way to use the energy of the sea waves and device for its implementation
Method and device designed to convert the energy of ocean waves into electricity. For the perception of wave energy using buoyancy, and to transfer this energy to the actuator vertical rods attached to playchest, and gear. Buoyancy feature in rails mines that perform delicate, the forces acting on buoyancy waves, are transmitted to the main shaft with gear racks by their impact on the ratchet gears, which are mounted on the shafts, with the rack set inside a box-shaped rod with the possibility of their moving, enter the toothed rack in engagement with rapovymi gears during movement of placesthe up and removed from engagement with the movement of placesthe down. Buoyancy are in the mines, rods mounted on the buoyancy inside the rod is the rod with the possibility of their cutouts to move around the rollers, ratcheting gear installed on the shaft and engages with the rack in its lowest position relative to the stem, and in its upper position the toothed rack out of engagement. The method and the device allow to increase efficiency and ensure efficiency. 2 S. and 3 C.p. f-crystals, 2 Il. the kinetic energy of sea waves into electricity.The number of known methods for converting sea wave energy into electrical energy, for example, patent RU 2004842 C1, EN 2153443 C2, in which the impact of each wave on the buoyancy of the or each roll from the swing of the pendulum mechanism on the wave receiving the rotation of the gear mounted on the main shaft, only one prong. With such intermittent and slow rotation of the main shaft is not possible to develop almost tangible electricity. Other methods, such as pumping air into the body of the unit for swing installation on the waves and the rotation of the air impeller (patent RU 311040) or using the impact of breaking waves on the blade wheel (patent RU 2004841), also do not justify their practical use because of the very low coefficient of performance (COP).For the prototype accepted way of using the energy of the sea waves, applied in the French patent 2319784 And, MCP 7 F 03 In 13/18. This method includes the perception of the energy wave through buoyancy and transfer this energy to the actuator via a gear mechanism consisting of a vertical rod with prongs mounted on the buoyancy vertically, and gear.The disadvantage of this method is n, ahadada in constant engagement with a pinion gear when lifting and lowering of buoyancy on the wave rotates in forward and reverse directions, and when this occurs stop the rotation of the gears when the buoyancy of the peaks and troughs of the waves. This mode cannot ensure the effective acceleration of the actuator, and hence the power required to justify the costs of making and using such devices. The opportunity to work with several such timing mechanisms, as the modules on a common main shaft of the actuator is excluded due to the inability to ensure synchronous operation due to various swing placesthe at different wavelengths and at the same time constant clutch teeth of the rods with the respective gears. Reversing the rotation axis of the gears creates additional difficulties in the implementation of the use of the produced energy. And these difficulties in the device according to the French patent 2319784 not overcome. In his description is not given a full view of the entire transfer sequence and converting the energy of waves.The present invention is a method - is to increase the efficiency and ensuring the health of the mouth of the receiving wave energy, have guides in the mines, which perform delicate, the efforts of the waves acting on the buoyancy transmitted to the main shaft with gear racks, the teeth of which are in the form of dogs, through their impact on ratcheting gears, which are mounted on the main shaft, with the rack set inside rods that perform box-shaped and fixed on playchest parallel guide shafts, enter the toothed rack in engagement with rapovymi gears during movement of placesthe up and take them out of engagement with the movement of placesthe down accumulate mechanical energy on the line of the main shaft with the flywheel and pass it through the gearbox to the generator.In Fig.1 is used in the method elements: buoyancy 1, the guide shaft 2, the shaft 3, the toothed rack 4, the ratchet gear 5, the main shaft 6, the flywheel 7, the gear 8, the shaft of the generator 10 and the generator 11.In contrast to the known method, which is only possible reverse rotation of the main shaft, stopping it twice during one period of oscillation of buoyancy, in the proposed method, the rotation of the main shaft is in one side, which provides an acceleration of the flywheel. The proposed CSP is the research Institute of the shaft and thus to achieve a given power installation, and with the gearbox (in the drawing it is represented in a simplified form the rim of the flywheel 7 and pinion 8") to increase the number of revolutions of the generator 11 to the values needed to produce electricity. Multi-temporal disordered swing placesthe 1 on the waves when using the proposed method not only leads to failure in the operation of the unit, but on the contrary, contributes to a more uniform dispersal and maintain rotation of the flywheel 7. The working stroke of the rack 4 is selected it up using buoyancy 1 because while pulling buoyancy 1 wave up can be obtained from wave energy. When lowering the buoyancy 1 down wave does not affect the buoyancy of other effects, in addition to maintaining her afloat, and the energy of free-falling buoyancy significantly less energy reported wave.For the prototype device is made, patented France 2319784 And as the closest to the proposed functional parameters containing such elements.The invention device is a constructive implementation of the proposed method.A special case of the complete device shown in the drawings, where Fig.1 presents a General view on the x mines 2, rods 3, gear racks 4, hrapovic gears 5, the main shaft 6, the flywheel 7, the gear 8, the threaded rim 9, the shaft of the generator 10 generator 11, the intermediate shaft 12, the satellite gears 13, the thrust bearings 14, the guide covers 15, anti-friction pads 16, the rings 17, the connecting bars 18 (Fig.2), the axes 19 and 20, the rollers 21, the rods 22, ROM 23, and the bearing structure (not shown).Buoyancy is made in the form of a parallelepiped. In the centre of buoyancy top 1 fixed in its lateral faces of the box-shaped rod 3 and the buoyancy of the weld through the pipe 24 (Fig. 2) in which the rod 22 with the ring 25 on its upper end. At the lower end of rod 22 is installed perpendicular to its axis, the disk 23. In a rack 4 is made arcuate guides cutouts 26, who missed the rollers 21 on the axis 20. Axis 20 is fixed on the lateral sides of the rod 3. On the sides of the stem 3, inside, outside locations of the rollers 21, installed anti-friction pads 16 with a gap between them and the toothed rack 4, ensuring the free movement of Reiki. On the upper part stem 3 is the ring 17. In the lower part of the rack 4 are made hole. In this hole, the holes of the slats 18 and earring 25 missed axis 19. Throaty Reiki inside of the rod 3. The main shaft 6 (Fig.1), the intermediate shaft 12 and the generator shaft 10 parallel to each other and are arranged horizontally. The main shaft 6 and the intermediate shaft 12 mounted in hard-support bearings 14 and connected to the satellite gears 13. On the main shaft 6 has a flywheel 7, the rim of which is made teeth for coupling with the gear 8, which is mounted on the shaft 10. Guides the shaft 2 is made of an openwork for easy rinsing them with waves and installed perpendicular to the main shaft 6. On the inner side of guide shafts, in their corners, set of pads 16 of antifriction material, for example PET (high strength carbon fiber, developed by the Central research Institute of Structural Materials "Prometey"), a lubricant which is water. Buoyancy 1 are located inside the guide shafts 2 can move in the vertical direction. Guides the shaft 2 and the housings 15, on the inner side which also have anti-friction pads (not shown), are arranged so that when the movement of placesthe 1 up the rack 4 are in engagement with rapovymi gears 5, and with a calm water of middle point height of the shafts 2 is at the level of the surface of the water. The average is 3 selected based on the normal scale waves in the area of installation of the device. All fixed elements of the device are rigidly interconnected parts of the supporting structure (not shown) that is installed on the stationary (near the shore) or floating (with retractable supports or anchors) platform. The number of modules, consisting of the guide shaft 2, the buoyancy 1 with the attached parts, ratchet gear 5 on one side of the main shaft 6 and of the same elements with the addition of the intermediate shaft 12 and the satellite gears 13 on the other hand, is installed as long as necessary to achieve the specified power generator or multiple generators. Install toothed rails 4 on both sides of the main shaft 6 increases the kinematic stability of the device. For compact placement of large power plants on the same platform with several lines for the main shaft.In the lower position of the buoyancy 1 and the toothed rack 4 and the rod 22 with the disk 23 under the action of gravity are in their lower position, the toothed rack 4 is provided in engagement with the ratchet gear 5 and runs through the strap 18 in buoyancy 1. When lifting buoyancy 1 wave of the toothed rack 4 curls through the ratchet gear 5 main shaft 6 with a force equal to the force of gravity water what about the shaft 6 with its rotation rail 4, the more buoyancy 1 is immersed in water, and, accordingly, increases strength, buoyancy buoyancy 1 up and contribute to overcome the resistance of the main shaft 6 with its rotation. This naturally included in the self-regulated mode "power steering". Reaching the crest of the waves, the buoyancy 1 stops moving up and starts to fall down. Terminated and the impact of the toothed rack 4 on the ratchet gear 5. Now promoted ratchet gear 5 acts on the rack 4, which slips his teeth on the ratchet gear 5 and moves it inside of the rod 3. At the same time the toothed rack 4 is pushed up by the rod 22 under the influence of the disk 23 water resistance due to the movement of the buoyancy 1 down. As a result of these forces, as well as to its own inertia and the toothed rack 4 its arcuate cutouts 26 rolled on rollers 21, finally departs from the ratchet gear 5 and has its upper position relative to the rod 3. When the buoyancy 1 trough stops its downward movement is terminated and the action of the oncoming flow of water to the disk 23. The toothed rack 4 by inertia and under the action of its gravity fall of uncrucified main shaft 6 on the subsequent rise of buoyancy 1. Described tightening of the main shaft 6 is only possible from one side. Agreed on the direction of rotation of the tightening on the opposite side by using the intermediate shaft 12 and the satellite gears 13. The flywheel 7 accumulates mechanical energy input of all installed modules, smoothes the rotation of the main shaft 6 and also serves as a part of the gearbox.If you need to output from any module corresponding buoyancy 1 with the rod 3 is raised to the eye 17 and is fixed in this position one of the known methods. The toothed rack 4 force rises up and locked in such position by means of the temporary insert placed between the float 1 and the bottom edge of the rack 4.The device, attached to the soil, such as fixed platform, is the most stable and therefore is preferably movable. However, in some cases, require mobile power sources for temporary power consumers in a given area or to use the excitement, the most favorable for the generation of electricity, generated in different areas at different times. For these cases, the supporting structure to establish what about the use of energy waves substructure, connecting the elements of the device in a single unit, are pivoted around the vertical axis of one of the known methods.To avoid damage of the device due to the impact of waves of destructive force or adverse ice conditions, the effects of tidal phenomena, as well as repairs substructure connecting the elements of the device in a single unit, made with the possibility of raising and lowering one of the known methods.As large water spaces excitement occurs within the vast majority of time, the mass use of the proposed device will not only provide electricity to the coastal areas, but also to transfer it into the overall energy system of the country, which will result in saving valuable fuel resources and labor required for their production, and significantly improve the environment.
