The invention relates to hydropower, and more particularly to wave hydroelectric power plants using energy waves that occur on the surface of seas and oceans, and is intended for power supply of fixed offshore platforms that have their own power plants to reduce noise and save energy when there is unrest.Currently, the supply of fixed offshore oil and gas platforms and pumping platforms transshipment complexes by using diesel or gas turbine power plants operating continuously n the nicknames noise impact on staff and major consumers of expensive energy.At the same time well-known wave hydroelectric power plants, which convert into electricity the energy of the waves and the open sea, and in the case of connecting them underwater cable with offshore platforms allows the excitement to disable their own power and, thus, to reduce noise and save energy.Wave hydroelectric Crab contains the pontoon posted on the unit, evenly spaced about the perimeter of the pontoon below the level of the water piston pumps with shaft and at least three flexible links connected to the anchors, each of which sequentially connected, at least two piston pump, with the pressure line piston pumps connected in parallel to the hydraulic unit.For flexible connection discharge highways piston pumps between themselves and posted on the pontoon collector unit has expansion joints.When the excitement of the pontoon effect by means of flexible connections on piston pumps, discharge line which is connected to the hydraulic unit producing electric current (see and.with. USSR N 1767208, CL F 03 B 13/12, 1992).For selection MTI use piston pumps, expansion joints and collector complicates the design of hydroelectric power.The presence of the pontoon, with positive buoyancy reduces the reliability and does not allow you to lock the wave hydroelectric power plant with a marine platform.These drawbacks are partially eliminated in the wave hydro uses the phase velocity of the waves.Known hydropower (see application France N 2369440, m CL F 03 B 13/12, 1978) contains a composite vertical support consisting of a floating platform with clamps and at least two reversible turbines placed in a horizontal cylindrical pipe installed below the water level symmetrically relative to the axis of the bearings and generators.The generators are located separately within the platform and connected to the turbines through bevel gears.Along the perimeter of the floating platform has a number of channels curvilinear forms with inlet holes, narrowing and shut-off valves to supply water from the sea through the exit holes of the button located in the upper part of the platform capacity, connected through piping with valves with horizontal pipes.Singing vector phase velocity of waves through a horizontal pipe runs the largest mass of water, posted by rotating them in a reversible turbine and located inside the floating platform generators that operate at nominal power.At the same time through the channels is filling the containers with water from the sea by converting the kinetic energy of the rolling waves in potential energy rise regardless of the direction vector of the phase velocity of the waves.The oblique wave is the rate of flow through the nozzles is reduced and the power drops.To stabilize the load hydroelectric open the valve on the respective pipelines and missing volume of water supplied from the tank under hydrostatic pressure in horizontal pipes before impellers of the turbine.The necessity of application of composite vertical support complicates the design of hydroelectric power and does not allow you to lock it with the marine platform.Fixed mount horizontal pipes with the turbines relative to the axis of the vertical supports, requiring the use of reversible turbines, the capacity of the canal system with shutoff valves and piping with valves complicates the design of hydroelectric power.The use of generators, which require a separate space precludes their placement in horizontal pipes with turbines and complicates the design of hydroelectric power.The present invention is to simplify the design and increase the reliability of the wave hydroelectric power.This task is achieved by the fact that known hydroelectric containing fixed on the bottom of the vertical support and at least two turbines, placed in a horizontal cylindrical pipe installed below the water level symmetrically relative to the axis of the bearing and the generators are equipped with two vertically spaced panels, a hinge mounted on a support made of solid piles of circular cross-section and pivotally connected with the formation of an acute angle, when this bearing is located on the bisector of the latter, and the nozzles are placed in the basket, and thus placed in the nozzles of the turbine is coupled with power of the capsule type.Turbines can be performed with the rotary blades.In the wave hydro as vertical supports can be applied one is correctly located shields, pivoted on a support made of solid piles of circular cross section and pivotally connected with the formation of an acute angle, when this bearing is located on the bisector of the latter, the placement of the pipes in the panels and mounting are placed in the sockets turbines with generators of the capsule type can simplify the design of hydroelectric power.Exception a floating platform having a positive buoyancy makes it possible to increase the reliability of the wave hydroelectric power.The performance of hydraulic turbines with rotating blades ensures stabilization of the load hydropower with the change in the phase velocity of the waves.The use of hydropower as one of the vertical supports, the vertical supports fixed offshore platform allows you to lock the wave hydroelectric power plant with a marine platform.In Fig. 1 shows a General view of the wave of hydroelectric power in the original position from the front; Fig. 2 section a-a in Fig. 1.Wave hydroelectric power plant includes a vertical support 1 with the clamps 2, 3 vertical panels 4, 5 with half rings 6, 7 and the plates 8, 9 and horizontal polnych shields 4, 5 with a horizontal pipe units 10 and 11 at a depth that provides full immersion of the panels at the level of the water when the wave height corresponding to the calculated phase velocity of the waves and is a solid pile of circular cross section.With this purpose in the upper part of the support at a certain height there are at least two pairs of clamps 2, which serve for the perceptual load of the mass of the vertical panels 4, 5 and transfer it to the upright support 1, and the head supports a pair of clamps 3 for fixing shields against accidental displacement along the support.The clamps 2, 3 are still on vertical pole using fasteners, structurally identical and differ from each other only top or bottom location of the horizontal support surfaces with which they come into contact with the corresponding surfaces of the half-rings 6, 7.Each saddle is a detail from an angular arc shape in plan, the internal radius of which is equal to the intermediate radius of the vertical support 1, and a height slightly less than the last.The ends of the clamps 2, 3 are closed by plates with holes in the center for fasteners.Intacta respective surfaces.For automatic orientation of the input apertures of the horizontal pipe 10 in the direction opposite to the vector of the phase velocity of the waves vertical support 1 is located on the bisector of the acute angle formed by the in terms of two pivotally interconnected vertical shield 4, 5.Thus the axis of the vertical support is located as close as possible to the top of the angle, which is necessary for the joint work of two movable panels under the action of the phase velocity of the waves is similar to a weather vane.As the vertical supports can be used one of the vertical supports of stationary offshore platform that allows you to lock the wave hydroelectric power plant with a marine platform.Two pivotally interconnected vertical shield 4,5 forming in terms of the acute angle a and rotatable around the vertical support 1, are designed for automatic orientation of inlet installed in the panels of the horizontal pipe 10 units 11 in the direction opposite to the vector of the phase velocity of the waves, which is necessary for the most efficient operation of the generating units.The principle of vertical panels similar action dveloped upravlenia to meet him, and in this case towards the waves.Vertical shield 4 is a rectangular plate form a rigid structure, which has the appearance of a straight line.In the front part of the shield in the middle of the height there is a hole for securing horizontal pipe 10 with the hydraulic unit 11 so that the axis of the socket is parallel to the bisector of the angle a.
Outside the front end of the vertical shield 4 at the top and bottom height there are at least two horizontal bracket to swivel with the shield 5.The shield, in turn, pivotally connected with the vertical support 1 using a half-rings 6, 7 and plate 8.Vertical shield 5 has a similar design, and differs from the shield 4 only in the presence of at least two pairs of horizontal arms and the shape of the plates 9.Swivel vertical panels 4, 5 are interconnected by a horizontal bracket is used for mounting panels on a vertical pole with clamps 2, 3.Half rings 6, 7 are provided for pivotally mounting the vertical panels 4, 5 plates 8, 9 on the vertical pole 1, located above the clamps 2 and are in contact with them through located e of the support surface, with the help of which they can rest against a corresponding surface of the clamp 3 by accidentally moving the panels up the side of a support and, thus, to fix them in position.In order to reduce resistance when turning the panels 4, 5 ring 6 and the clamps 3 are set with a gap height.Each of the two half-rings 6 is a detail of the channel profile in the form of a semicircle, an inner radius which is slightly greater than the outer diameter of the vertical supports 1.The ring 7 is similar in construction and differ only in the fact that made of the angular profile.The ends of the half rings 6, 7 are closed by plates with holes in the center for fasteners.Connectors semirings shifted 90oin terms relative to the plane of the connector clamps 2, 3 for continuity of contact corresponding surfaces.Plates 8, 9 are used for the fixed connection of the vertical panels 4, 5 semirings 6, 7, provide a given acute angle in plan and the location of the axis of the vertical support 1 on the bisector of the angle as close as possible to the top to create the effect of a weather vane.At least two plates 8, 9 hard con is performance communications boards with the corresponding half rings, which, in turn, being connected end-to-end work as a whole, providing free rotation of the shields around the pole.Between the plates and the flanges are equipped with ribs.Horizontal pipes 10 are intended for fixed mounting units 11 in the vertical panels 4, 5 below the liquid level, as well as ensuring uniform distribution of the velocity field in the flow of water before the turbines and represents the nozzle has a cylindrical shape with open ends, the longitudinal axes of which are parallel and symmetrical to the bisector of the acute angle a between the boards in the plan, as close as possible to the vertical support 1 and the top angle to create the effect of a weather vane.The cut plane of inlet nozzles are flush with the hinge connections of the vertical panels, and the ends of the outlet openings made them symmetrically relative to the centers of gravity of the horizontal pipe 10 units 11 that are on the same straight line with the center of gravity of the cross-section vertical supports to optimize the bearing load from the mass of units.To increase the flow speed of the water through the turbines of the straps 11 are used for the direct conversion of velocity head sea waves into electricity and are non-reversing flow bladed turbine with rotary blades, coupled with power of the capsule type.Units coaxially fixed within submerged under the water level of the horizontal branch pipe 10 by means of three radial bearings, which are evenly spaced around the circumference.Hydroelectric power plant operates as follows.In the initial position of the inlet of the horizontal pipe 10 units 11 and the vertex of the acute angle a formed in terms of two pivotally interconnected vertical panels 4, 5, submerged under the water level and, in turn, hinged on located on the bisector of the vertical angle of the support 1, is directed in the direction opposite to the vector of the phase velocity of the waves.When moving waveform from front to back with a design speed the speed the pressure of the mass of water passing through the horizontal pipe 10 acts on the blades of the turbines that convert the kinetic energy of water currents in the rotating shafts of the generators that produce electric current.While turning the blades of the turbines are in middle position with a certain angle of attack.When increasing the phase velocity of waves in the cases load wave hydroelectric power is stabilized.Supply of vertical supports two vertically spaced panels, a hinge mounted on a support made of solid piles of circular cross section, and pivotally connected with the formation of an acute angle, when this bearing is located on the bisector of the latter, the placement of the pipes in the panels and aggregatirovanie placed in the nozzle turbines with generators of the capsule type can simplify the design of hydroelectric power.Exception floating platform having positive buoyancy, makes it possible to increase the reliability of the wave hydroelectric power.Running turbine with rotating blades ensures stabilization of the load hydropower with the change in the phase velocity of the waves.The use of hydropower as one of the vertical supports, the vertical supports fixed offshore platform allows you to lock the wave hydroelectric power plant with a marine platform and, thus, in the presence of agitation to reduce noise and save energy. 1.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.
