The invention relates to the field of shipbuilding and can be used in the construction of seagoing ships, however, the use of the proposed device allows to obtain an additional source of energy by the utilization of wave energy, causing rocking of the ship.Known wave power plant, the content is, podklyuchenie to energy units (see and.with. USSR N 1213239, F 03 IN 13/20, 1986).The disadvantage of this solution is the impossibility of its use as a bilge keel (the stabilizers), as impossible rigid fixation of one of the float relative to another and, accordingly, there is no resistance to rolling of the ship from side to side, in addition, well-known designs will be great resistance to the movement of the ship.Also known Malar keel, made in the form of blades placed on the underwater part of the hull (see Marine dictionary, M., Transport, 1965, 114 S.).The disadvantage of this solution is the limited functionality of the device.The task, which directed the claimed solution is expressed in expanding the functionality of the device.The technical result obtained by solving the functional problem may be defined as providing more energy.The problem is solved in that the bilge keel, made in the form of blades placed on the underwater hull of the vessel, characterized in that the blade is bonded to the hull articulated, with vozmojnostey piston, the rod of hydraulic cylinder pivotally connected to the housing of the vessel, while the cylinder cavity on both sides of the piston are connected with the hydraulic accumulator, with bilge keels are placed symmetrically relative to the longitudinal axis of the hull.Comparative analysis of the characteristics of the claimed solution with the characteristics of the prototype and analogues demonstrates compliance of the claimed solution to the criterion "novelty".The characteristics of the characterizing portion of the claims, solves the following functional tasks:
Sign ..."the blade attached to the hull of the hinge, with the possibility of rotation gives the blades mobility and, thus, provides the possibility of "removing" energy experienced by the blade during its interaction with the surrounding water environment.The characteristic that defines the orientation of the axis of rotation of the blade enables energy recovery side rolling of the ship.Features "one of the surfaces of blades pivotally connected with provided with a piston rod of a hydraulic cylinder pivotally connected to the housing vessel, describe the mechanism that transform a "rocking" motion of the blades into mechanical energy.Sign "of the cylinder cavity n the m position and even active opposition to motion by a corresponding movement of the blades.The sign "bilge keels are placed symmetrically relative to the longitudinal axis of the hull ensures the symmetry of effort on the hull of the vessel arising from the operation of the device.The figure schematically shows the claimed device.The drawing shows the Board vessel 1, the blade 2, the hinges 3, the rod 4, a cylinder 5, a hydraulic accumulator 6, hydrographically node 7, the nozzles 8 and 9, the pipeline 10, the piston 11, gear 12, the surface of the sea 13.The blade 2 is pivotally connected with the hull of the vessel can be rotated about a horizontal axis by a hinge 3. The stem 4 and the cylinder 5 to form a hydraulic cylinder double acting, the cavity of which, located on both sides of the piston 11 through the pipes 8 and 9 and pipe 10 connected with hydrographically node 7 hydraulic accumulator 6. The cylinder body 5 and the end of the rod 4, by means of hinges 3 are connected, respectively, with the vessel and the blade 2.As gidroraspredeliteli node 7 can be used in any device of similar purpose, satisfactory characteristics operating conditions and having a remote, preferably automated control switch channels. As t is the proportion of known construction, supplying in the pipeline 10 fluid pressure less than the hydraulic accumulator.The claimed device operates as follows.When the device is in the mode of the power plant.Hydrographically node 7 is in the state, consistently providing the ejection of the fluid compressed in the cylinder cavity 5, in the cavity of the accumulator 6 through the pipe 8 and the corresponding pipeline 10, and the inverse reset (fill) in the cylinder chamber 5 of fluid under low pressure from the cavity of the accumulator 6 through the gear 12, the nozzle 8 and the corresponding pipeline 10. When the blade 2 has full freedom of movement.When the side rolling the appropriate Board 1 ship sinking deeper and deeper into the water, the blade 2 is valid hydrodynamic force tends to turn the blade free end to the surface of the sea 13. This leads to the movement of the piston 11 into the cylinder 5, and then discharge the compressed fluid in the cavity of the accumulator 6, the motion of the ship in the opposite direction, the piston goes down, and the cylinder chamber is filled with working fluid under low pressure, then everything is repeated. This ensures that the tire and mechanisms or other purposes.When the device is in the mode of Malar keel.Hydrographically node 7 is in the state, providing a supply of high-pressure fluid from the hydraulic accumulator cavity 6 in the cylinder cavity 5 (on both sides of the piston 11). When the blade 2 is fixed at a certain angle to the hull.When the side rolling the appropriate Board 1 ship, sinking deeper and deeper into the water on the blade 2 occurs hydrodynamic force, seeking to prevent such rotation of the hull of the ship. When this cylinder is rigidly fixes the position of the blade 2. Malar keel, made in the form of blades placed on the underwater part of the hull, wherein the blade is attached to the hull of the hinge, with the possibility of rotation about the horizontal axis, with one of the surfaces of blades pivotally connected with provided with a piston rod of a hydraulic cylinder pivotally connected to the housing of the vessel, while the cylinder cavity on both sides of the piston are connected with the hydraulic accumulator, with bilge keels are placed symmetrically relative to the longitudinal axis of the hull.
