(57) Abstract:Usage: to convert the energy of wind waves in the pond. The inventive outside sides of boats placed in the tank, partially filled with the working fluid and interconnected by a pair of conduits with hydraulic turbines and devices, providing alternate flow of the working fluid to flow during rolling. This turbine is installed in the end of the conduits at opposite sides. Turbines can be placed in the upper part of the conduit, and the fluid flow before the turbine dispersed through narrowing the flow-through portion of the conduit regulating flap. 1 C.p. f-crystals, 2 Il. The invention relates to hydropower, in particular to energy converters energy of wind waves.Known inertial energy Converter pitching of the vessel. In the underwater part of the boat by this method is freely suspended inertial load, which in relation to the case rocking the boat performs oscillatory motion. These oscillations using gears is converted into rotational motion of the propeller.The disadvantages of the method are the low casinogo oscillating weight, which is under strong excitement poses a great danger to the ship and crew.Closest to the present invention is a method of energy conversion pitching floating means by which the energy of the fluid motion, in turn iridescent when rolling through hydraulic turbines installed in pairs of conduits connecting the opposite compartments onboard tanks (U.S. Patent N 4207739).According to this method, the tank with the working fluid located in the holds of a floating platform or vessel. In this event, the layout of the cargo compartments, cabins and office space. In addition, hydroturbines placed in the middle between the hydraulic tank, which significantly reduces the possibility of achieving a higher capacity turbines.The purpose of the invention to increase the capacity of energy Converter pitching.The aim is achieved in that in the method of energy conversion pitching floating means by which the energy of the fluid motion, in turn iridescent when rolling through hydraulic turbines installed in pairs of conduits connecting the opposite compartments onboard tanks, tanks with the working of the LM is at the end of the conduits at opposite sides. In addition, hydraulic turbines installed in the upper part of the conduit at its end, and the fluid flow before the turbine dispersed through narrowing the flow-through portion of the regulating flap.With this method of energy conversion pitching power Converter power pitching increases by about 3-4 times. The vessel remains intact bilge volumes, not broken layout of compartments and cabins. The vessel retains the ability to perform their mission.Schematic diagram of the installation for energy conversion pitching floating means of the proposed method is shown in Fig.1 and 2.The unit is mounted on a ship or a special platform, requiring Autonomous power plant. On the housing with the outer part of the sides of the vessel 1 along the left and right sides are tanks 2 and 3, each of which is separated from the adjacent blank wall 4. Tank left side connected to the opposite tank right by means of two transverse conduits: odd 5 and even 6. At the end of odd conduits 5 the starboard side are hidrocarbonetos 9, 11, and in the end even conduit 6 turbine generators 10, 12 are installed at the s or kardannyy couplings. If the connection shaft is difficult, it can be applied synchronized parallel set of electrical generators, a well-established energy systems.Each hydrosorbent 9 or 10 in the direction of travel of water along the transverse conduits mounted flap valve 7 (Fig.2), and before each of them regulating valve 8, the position of which is controlled using a simple technologically developed an automatic control system.The energy Converter pitching works as follows.When the roll of the vessel with agitation to starboard water or other working fluid from the filled tank 2 shimmers along the transverse conduits 5 in the tank 3 starboard. In the narrowing of the regulating valve 8 its speed increases, at the same time increases and the kinetic energy of water flow. Moving through the conduit, the water spins the blades of the impeller turbines and rotors paired with them generators 11. It produces electric energy through known in electrical engineering stabilizing device (not shown) is supplied to the electric drive ship propeller.When the roll saya rotor hydrocarbonization 10 and paired them with generators 12. Turbine starboard at this time rotate by inertia.Valves non-return valves 7 reverse current water closed and looking in the opposite direction of the water flow does not affect the blades hydrocarbonization 9 starboard.Moving by sea vessel simultaneously participates in onboard and pitching motion. The surface of the deck is arbitrary position in space, resulting in the load on the turbine fore and aft of the vessel will be different. Connection all along one side of turbogenerators one common shaft preferable, since such connection will allow you to average the difference in the hydrodynamic effects of water flows.In the absence of pitching that in the seas and oceans is extremely rare, has a backup traditional engine, providing reliable mobility and maneuverability of the vessel.The calculation of the energy Converter pitching was made for a ship with a displacement of 3000 tons, a length of 105 m, width at the sides 18 m, width of the hull side tanks Converter 24 m, depth 7.5 m, speed 13.5 knots (25,5 km/h). Power replaced the main engine 2200 kW.In Fig.2 schematically shows a roll of the vessel with an angle of 15about. Scheme at a scale of 1:200. The excess level of water in the tank left side towards the tank right is 6 m, and exceeding the level of the water against the blades of the impeller turbines 5,3 m Based on the excess of 5.3 m selected speed of movement of water along the transverse conduits 3.5 m/sWhen the cross-section of the conduit (for a single turbine unit) 2,5x5 m capacity 43,75 m3/s and a throughput of three even (or three odd) conduits for the selected vessel is 131,25 m3/s taking into account local resistance emptying of the left (or right) tanks will happen in 4.5 s, which will ensure the completeness of the energy of falling water.Power hidrocarbonetos determined in accordance with the known expression for the Converter pitching is 4662 kW at an angle of roll 15about. The estimated capacity of power plants (2200 kW) is provided by the Converter pitching at an angle of roll of 5.5about.Inertial coasting rotating mass single-breasted hydrocarbo the spine of rotation of the turbine 300 rpm He will stretch the duration of the pulse of the water flow at 0.2 C.Thus, the energy Converter pitching for the proposed method will provide a great saving of fuel and energy resources. The savings is achieved by the fact that in the proposed method, more than 90% is excluded from the main staff of the ship's engine. Reduced consumption of chemical fuels will improve the ecological situation in the seas and oceans. In addition, the energy Converter pitching mounted on drifting or moored platforms offshore energy and chemical complexes will allow you to solve the problem of energy supply. 1.
