Turbine technology and offshore power plants for general focusing , increase and conversion of kinetic ocean energy
Technical Field
The present invention relates to turbine technology and offshore power plant for the general focusing, increase and conversion of kinetic ocean energy from waves, tides and ocean currents in common technical solutions.
Background
Over the last hundred years there have been significant new knowledge and theories related to ocean energy. Research and numerous pilot and pilot projects have been implemented worldwide. Suggested solutions for converting wave energy can be divided into 5 to 1 0 groups by type of technology, location, end use of energy and size of the power plant. Four classic main groups within the reshaping of ocean waves, divided according to the size of the plants are ; pointdampner, attenuator, plant for "oscillating water columns" and determinator.
The primary energy conversion taking place at wave activity driver usually a piston device which creates hydrodynamic or pneumatic energy that must undergo secondary energy conversion by means of the turbine or hydraulic motor before the tertiary energy conversion may be provided by electricity producing generators.
Pointdampner is most often a bending device on or just below the surface that moves with the wave activity and activates a piston in a cylinder which is anchored to the sea such as the Australian company Carnegie its underwater buoy. Some pointdampner have gas or liquid -filled sac that utilizes pressure variations under waves agitating movements. The buoys can have internal generators as the Norwegian "Lifesaver". The Finnish -made buoy "Wave Roller" is also a pointdampner which internally has vertical axel excentric which operates generators. The Irish company "Ocean Energy" its wave-rig and the Norwegian "ocean energy rig" belongs to the group attenuators or breakwaters
that utilizes pressure variations that occur in the chamber of the waves o r in oblique channels where the waves themselves are piston and creates wind that drives the air turbine. Scottish wave power plant "Limpet" inverter on a larger scale the wind that occurs over oscillating water column movements inside the plant in the coastal zone.
The primary energy conversion for the latter three devices are from ocean waves to wind and where further energy transport and transmission occurs by directional alternating flow of secondary energy conversion. Common to attenuators and oscillating equipment is that they utilize so-called "Wells turbines" which effects rotating mechanical energy to the tertiary energy conversion which is essentially electrical generators.
The determinants Catalysts are preferably large and has its extent paralle l to the wave front. From this type include Scottish "Oysters" which is a bottom - anchored and articulated surface formation which moves inwardly and outwardly in the waves and operates piston devices that creates hydraulic energy connected turbines and generators on land for the production of the final energy.
From published Patent WO 201 3/1 71 551 A1 discloses a vane which has a circularly arranged series of stiff flaps that are hinged to the surfaces perpendicular to the center body or between such surfaces and the core and mounted on or between modules.
For conversion of tides and currents that, many different variations of substantially traditional turbines with three flaps that are designed for mounting on the seabed. Some turbines rotate 1 80 degrees arou nd the tide change, others turbines rotate their flaps and a third group has flaps that rotate in the same direction during alternating flow directions. Turbines for tides and currents often have higher efficiency because the primary energy conversion take s place by the flaps in the sea, and the performance is transmitted as rotational mechanical energy directly to the generator. Among the above groups which may be mentioned tidal turbines to the Scottish company "Meygen" and Norwegian "Hammerfest Strom." Furthermore there is the tidal turbine rotating inside the horizontally oriented cylindrical structure and turbines with a flap that is mounted to the vertically positioned annular arrangement.
The objections against existing technologies for converting kinetic ocean energy, may essentially be summarized with that they do not utilize more of the ocean's movement resources simultaneously. Valuable amounts of energy from ocean waves and tidal waves occur always in the same waters and force components of the ocean are part of what we commonly designate as tidal power.
In addition, the fact that the specific energy conversion, either from sea waves or tidal waves, have a relatively low efficiency and high investment per kW average annual production. Moreover, existing solutions ready capacity-related and size constraints and can not survive offshore or included in combination with other energy systems and installations in the open sea. By far the majority of wave energy converters are designed to be integrated and work as small power plants in coastal areas. In addition, energy systems for converting wave energy can not transform the remaining kinetic ocean energy in the area resulting from tidal waves and currents.
Energy Plants for converting tidal waves and currents are often mounted on the seabed where these forms of kinetic energy has its lowest values. In addition converts the little or no energy from the ocean waves in the region.
The general objection about low efficiency due primarily to poor efficacy in th e primary and secondary energy conversion. In addition, usually a tertiary energy conversion to final energy in the form of electric generators. Further energy losses have already occurred during the energy transport between these devices prior to final connection to the electricity grid.
In most oceans, there is a combination of waves, tides and currents. The energy content of the ocean has great variations during a calendar year and the average energy content from one ocean to another can for many reasons show significant differences. Energy from tidal waves have their cycles during the day and season. Variations in average energy content within one year, for ocean waves range from 20 kW to 30 kW per meter along the wavefront to about 1 00 kW / m in some waters.
Ocean waves, tides and ocean currents is kinetic energy, or the performance in terms of water masses as follows complicated and uncomplicated movement
patterns which are integrated in each other. Various known technical solutions for converting kinetic ocean energy has in common is that they attempt to exploit "their" special part of the movements in the sea. Continuing to illuminate how a technical solution can leverage all the complex movements of the sea in its conversion to another performance.
The propagating waves of the sea surface represent the challenging complexity in this composite image. The upper part of the water in a wave moves vertically, but in addition, force component in propagation direction. Further down, there are more horizontal pendulum movement that supplies the wave crests and wave troughs makes possible. Increasing wave heights has substantially increasing wavelengths. Energy, momentum or power of ocean mass movement goes ½ wavelength down into the ocean, but over 90% of this energy is collected in the upper 1 /4 of the wavelength. Slightly below the wave troughs is the changeover it up and downward wave movement is close to the more horizontal back and forth oscillation.
This changeover is moving upward in the sea at decreasing wave heights and goes far deeper with increasing wave heights.
In addition, the fact that it often is more wave directions simultaneously, namely "chaotic waves", and there are always varying wave heights, wave lengths and frequencies.
It further enhances or increases energy of many waters and seas are powerful tidal currents that regularly changes direction several times a day. The currents will in some waters and sea areas coincide with a tide direction and enhance the resultant, and then to reduce the flow rate in the opposite direction. In summary, it is important to note that each of the three forms of kinetic ocean energy; wave activity, tidal and ocean currents have their largest amounts of energy in the upper ocean and the sum will therefore definitely be greatest here. In some areas, currents far below the surface have different speeds and directions. The kinetic energy of the image composition is in continuous motion and change.
Over the last few decades of research, testing and development that underlie the creation of the new technical solutions for general increase and reshaping of
the three forms of kinetic ocean energy in common technical solutions. The new technical solutions is also based on the principles of how the human heart anatomy and physiology creates hydrodynamic energy in closed circuit and applies these principles to the design of the present new technical solutions that make intervention in and transform kinetic ocean energy under more open conditions.
The kinetic ocean energy consists mentioned by several different movement patterns that are fully integrated with each other. Coinciding directions can increase momentum in shorter phases or over longer periods of time and may similarly have opposite effects. As the movement patterns are integrated into each other, it is appropriate to transform the kinetic ocean energy in common technical solutions addressing any combination and variation in energy deposits within selected size and values.
In its efforts to find new technical solutions to energy conversion from three forms of kinetic ocean energy in common technical solutions represent the wave energy composition and variation of energy content the biggest challenge, and will often be decisive for the design, dimensioning and installed capacity of a power plant. Movement speed for tides and currents, and wave height sideways movement is essentially the order of 1 m / sec to 5 m / sec. But sea waves propagation opening has about 5 to 1 0 times higher speed in the horizontal direction than the vertical movements from trough to crest and both take place simultaneously.
In connection with the development of the present invention, it has been the aim to enable: (I) capturing the complex energy transport in the sea in a way that makes it possible to transform a variety of momentum components in size and direction to another form of performance;

(X) that the power plant can maintain its position in the sea surface under changing tide levels; and (Xi) that the power plant can follow undulations with energy content that goes far beyond the plant's production capacity.

Description of embodiments
On Figure 38 in the attached figures are the common principles for the behavior of the human heart illustrated. The heart causes hydrodynamic energy in a closed circuit, and flap turbines which engages and converts kinetic ocean energy under more open conditions. The heart valves 3 opens immediately upon correct flow directions and retains an open position until the pressure conditions change and closes instantly when the pressure is higher on the opening side than on the inside flaps. " Tricuspidal turbine " shown in middle, six flaps 3 which are oriented with the same closing direction and is mounted on the turbine sleeve 7 and fastened around a center shaft 6.

The present invention encompasses the more technical flap turbine right of the figure sheet is provided with elastic flaps in the working phase, pressed into the curvatures on turbine arms. Further included in flap turbine structural structure support rings and outer support rings.
There is thus provided a flap turbine for converting kinetic ocean energy from sea waves, tides and sea currents, which flap turbine comprises a plurality of flaps that are rotatably or movably attached to the flap turbine so that the position of each flap is individually adjustable between a closed position and an open position in response to the pressure in the water around each flap and independently of the other flaps.

Preferably, the circumferentially be several turbine arms and / or turbine discs with cutouts or support flaps in flap turbine longitudinal direction. Flaps may be oriented in respectively the turbine longitudinal direction and with more radial lines turbine arms or flaps can be more radial lines or without longitudinal turbine arms.

Turbine arms may further be provided with respective pendulum arms, on which the pendulum arms a plurality of flaps are rotatably or movably mounted .
The flaps can have a curved shape or may assume a curved shape in a cross section perpendicular to the flap to the longitudinal direction . The flaps are preferably made from a resilient material such that the flap end gets a suspension effect across the flap to the longitudinal direction at varying load .
The flaps may comprise two parts which are rotatably supported about a common axis of rotation of flap the longitudinal direction .
Turbine arms or the pendulum arms are preferably provided with recesses with a shape corresponding to the flaps cross-sectional shape, and the flaps are preferably mounted so that they lie in their respective recesses in their working positions.
Flap The turbine can be designed with an open core and turbine arms can then be mounted on support rings with a short axial extent so that water can flow radially and axially through the at least one flap turbine core. Flap turbine may
alternatively be formed with a closed core, preferably in the form of a cylindrical element.
The at least one flap turbine may further comprise two or more concentric turbines which rotate in the same direction or in opposite directions. There is further provided a power plant for converting kinetic ocean energy from sea waves, tides and sea currents, which power plant comprises :
- At least two power modules (1 7, 1 8 ) arranged side by side to form a force conversion channel ( 21 ) between them, and
- At least one flap turbine (1 , 2) as described above , wherein the at least one flap turbine is arranged in the power conversion duct ( 21 ) and is rotatably supported in the power plant modules (1 7, 1 8).
Each power module preferably comprises at least one bone as seen from the side, is inclined or perpendicular to a horizontal plane, and one or more flap turbines is rotatably supported in the corresponding legs of two power modules which are arranged next to each other.
Each power module can comprise two legs which, viewed from the side, is inclined or perpendicular to a horizontal plane, and one or more flap turbines is rotatably supported in the corresponding legs of two power modules which are arranged next to each other. Power plant modules, front view, is preferably substantially vertically oriented relative to a horizontal plane.
At least one of the power modules can be provided with at least one movable plate member for compressing the kinetic ocean energy to the at least one flap turbine. Power plant modules may comprise a hull shaped upper part the inclined legs are attached to and which is preferably at least partially extending above the water surface when the plant is in use.
The plant preferably comprises at least one link element which in one end is movably attached to a power module or module bone on one of the power plant power modules and its other end is rotatably attached to an anchor element on the seabed when the plant is in use.
The power plant can be designed so that it is anchored by at least one link member to another power plant as described above in which the link element the two ends preferably movably attached to the respective power plants.
There is thus provided a power plant for general increase and conversion of kinetic ocean energy from sea waves, tides and ocean currents which preferably comprises at least two power modules which are arranged next to each other so as to form a power conversion channel between them. The power plant further comprises at least one flap turbine arranged in the power conversion duct, and which is rotatably disposed between the power modules. The at least one flap turbine comprises a plurality of flaps preferably distributed around flap turbine and outside each other and are rotatably or movably attached to the flap turbine so that the position of each flap is individually adjustable between a closed position and an open position in response to pressure in the water around each flap and independently of the other flaps.

By increasing wave heights increasing the speed of all turbines and energy output increases linearly. Upon further increase in wave heights may incrementally activated several energy producing units .
The new power plants feature enables maintenance of the kinetic ocean energy movement cycles during sustained and gradual transformation of energy to another form of performance using a plurality of units of primary energy converters described as flap turbines. This reduces unnecessary loss of momentum during the stepwise process to another performance, increases overall efficiency and strengthens the economy of power generation from kinetic ocean energy.
Overproduction can in different ways be stored or used for energy-intensive manufacturing in or associated with the plant. Such storage may be done with compressed air, rechargeable batteries, hydrogen production from water electrolysis (wherein hydrogen produced therefrom later used in a fuel cell for the production of electricity), but is not limited thereto.
One of the main criteria when developing the Backq power plant has been to achieve a powerful rotary movement or directional and persistent rotation already at the primary energy conversion regardless of the kinetic ocean energy complex movement patterns and large variations in energy content. Structural policies and behavior of flap turbines provide an optimized kraftorming from all forms and combinations of hydrodynamic energy deposits to the rotation in the selected direction of rotation.
A second main criterion has been that the power plant units must not be too high, since it is physically difficult to embrace the water mass scale and movements, both at short and long wavelengths with associated variation of energy down into the ocean. Mutual velocity variations in more voluminous water masses is a challenge in itself, and in particular in relation to the rotating primary energy converters. It is therefore important to preferably increase the number of energy transforming units if one wants a significantly greater energy production. At the same time a substantially higher efficiency. It is only by repeating processes it is possible to transform a variety of different force components to high efficiency without causing unfavorable reflection and change of flow directions. The remaining kinetic energy after an energy conversion, the input value for the next similar process and several energy transforming devices provide better utilization of resources and higher total capacity. Each energy converter, which preferably is part of a larger group of flap turbines will each have higher rotational speed. Overall, this will provide smoother energy production by lower resource base gets a higher efficiency, and large deposits exploited in relation to maximum installed capacity. The following conditions have been particularly emphasized during development of the present invention: a. the density of water is about 838 times greater than that of air; b. unaffected speed of the ocean's kinetic energy varies substantially between 1 m / sec to 5 m / sec; c. in open water is about 90% of the energy of sea waves in the upper L / 4, where L is the wavelength;
d. the energy of the tides and ocean currents are essentially the greatest in the upper part of the ocean; e. ocean kinetic energy increases to the square of possibly achieved higher speed of movement; f. wave spectrum and maximum variations within significant wave height represents an enormous challenge in their energy content; g. the complexity of the composition of wave directions and other mutual variations in the three forms of kinetic ocean energy; h. structuring potential by enabling movement in the same plane; in. large tidal variations and tidal waves coming regardless of wave activity and may increase or decrease the energy content; j. plant's ability to cope with the biggest wave heights included in the calculation of the relevant sea area significant wave height; k. occasionally need for greater energy production than actually kinetic ocean energy at the moment dictates;
I. facilitate maintenance of maximum energy production under wave conditions far exceeding installed capacity; and m. possibility of temporarily storing kinetic energy as potential energy during energy conversion, for bonding and utilization of extraordinary momentum components.
Power Plant Units and power conversion channels:
A basic requirement for an offshore power plants is that the structural principle of the sea permit and ensure mastery of extreme weather situations based on measurements and calculations for the relevant area. In practice, this usually means that the biggest ocean waves included in the calculation of significant wave height, mega-waves and 1 00-year wave must be emphasized during calculation of structural strength sufficient longevity.
Power plants for general increase and conversion of kinetic ocean energy can have very many different sizes after wave conditions and location in an ocean. A single plant can have several types of vertical lines power modules that are
divided into primary modules, intermediate smaller secondary and tertiary modules. All module sizes may preferably, but not necessarily, have internal cavities for power transmission and further energy conversion as well as other technical installations. For example, the gear arrangements, electrical generators and control systems in this way be mounted in the immediate vicinity of the primary energy conversion which takes place on the outsides of power modules. It can be used both hollow and massive power plant modules is structurally interconnected by means of flap turbines with and without turbine cores or other transverse connection between the modules. Stress-absorbing connection between the main components may, for example made possible in that both sides of the turbine cores go partly into the power plant modules and are connected by intermediate elastic and shock absorbing materials, which facilitate movement in several or all directions. Turbine cores and its outer ends can be cylindrical, having conical shape or have a short surface "locking" cylinder, be wholly or partially spherical, and may further have consistently conical locking pin that is completely or partially enclosed by corresponding elastic and shock absorbing material. Inside the turbine cores may preferably be cavity for rotary mechanical energy in addition to the cavity for the wiring and piping between the modules. The largest turbine cores imaginable allows for person passage and even transport operations in connection with energy bridges.
All types powerplant modules causes wave diffractions and wave defractions, as well as audiovisual structuring the kinetic wave energy and together with turbinecore will help ensuring all these construction elements for permanent increase of energi level operation between the power plant modules Number of which a simple and / or concentration of flap turbines is montert.
Along the surface a power module having one sufficient length the Desired Number flap turbines and any other integrated PLANT. It can be beneficial stream construct modular bone in front and acts as part of one power module . These legs can point Addition two running against incoming oceans and can preferably have an angle of about 30 to 60 degrees, but the angle can be both larger and smaller Relatively less.
Along the surface of the sea, a power module having a sufficient length for the desired number of flap turbines and any other integrated systems. It may be advantageous to construct the module legs in front and rear as part of a power module. These feet can point outwards towards the incoming ocean energy, and may preferably have an angle of approximately 30 to 60 degrees, but the angle can both be substantially greater and less.
Power plant modules and module bones can structurally subdivided into different smaller elements in their joints have stress absorbing material similar to that previously described with respect to modules and turbine cores. Module Height, width, thickness and depth must be assessed in relation to the wave conditions and other kinetic ocean energy in each individual waters.
Two power modules and intermediate turbines and turbine cores constitute a power plant unit with intermediate power conversion channel. Each power plant unit is preferably connected to adjacent modules to form larger power plants. Power plant unit can also be constructed so that they can move up and down under heavy waves regardless of the neighboring unit vertical positions and movements. Power plants that are built up in this way, in principle has vertically divided power modules and module legs with planar surfaces and connection profiles that slide relative to each other. For some waters, some power units be vertical pendulums and other be permanently connected or have stress absorbing devices.
Flap wheels with and without cores and concentric turbine solutions:
Size or diameter and type flap turbine can vary in relation to energy instance, turbine placement and the total number of turbines in the power plant. It can also be used a standard size of flap turbines across the energy plant despite the fact that the kinetic ocean energy in general, and the wave energy in particular, has its largest value in the upper quarter of the wavelength. Given the great variety of wave lengths and wave heights, it may be advantageous to have groups with less flap turbines top and slightly withdrawn to the inlet power conversion channel. In level below these and further forward in the power conversion duct may preferably be flap turbines of larger diameter. Deeper down to diameters again reduced. Flap turbines will not distinguish between the kinetic ocean energy various compositions as waves, tides and
currents. A number of such flap turbines will therefore capture a significant share of total kinetic ocean energy in the relevant waters.
The movement directions that are not parallel to the power conversion duct extent, will change direction when the sea waves, tides or currents, reaches the power plant. Waves agitating movement or propagation direction will be changed by disturbances caused by module's legs and flap turbines causing refraction and diffraction. Wave speed is reduced for that part of the wavefront that first reaches the power plant and we get deflection by refraction. In addition, the effect of diffraction, waves characteristic trait to change direction when they pass an object into the sea. Wave deflection is possible with up to 90 degrees, meaning that even ocean waves advocacy toward offshore power plant across the energy plant extent, will change direction as the waves reach the energy plant's first power plant module, to eventually go virtually straight into force reshaping canals where a number of flap turbines are responsible for the primary energy conversion. Regardless of the water mass complexity in composition and variation of energy and movement directions, flap turbines capture the different force components as they are or coincide with one or more flap turbines rotation. Water mass movement and changes in local pressure conditions shutter flap turbine flaps and capture momentum if the movement speed is greater than the individual turbine rotation speed at the moment. The momentum components have low movement speeds to affect the quickest front turbines, will relinquish some of the momentum for a later turbine series with other power components that were reduced by passing anterior turbines.
For example, part of the wave motion speeds coincide with resultant tidal wave and ocean while horizontal movement. In such situations the flaps along several turbine arms close simultaneously and contribute to the turbines' rotation by conversion of multiple forms of kinetic ocean energy simultaneously. The first turbines are "taking down "the differences in movement speed, or more precisely, they reduce the quickest momentum components in energy conversion and all movement speeds in different vertical directions becomes more and more uniform. Gradually decreases the composite kinetic energy during passage through a number of flap turbines in power conversion channel.
For flap turbines will the number of revolutions per minute increase with increasing energy from tides and currents and further increase with increasing wave activity.
For most practical purposes we can say that the rate of tides, currents and wave height transverse movements are of the order of 1 m / sec to 5 m / sec. Ocean wave's horizontal propagation, however, has about 5 to 10 times faster than vertical movement from the wave trough to wave crest and both take place simultaneously. Flap wheels preferably has many turbine sleeve, shuttle sleeve, turbine discs or other suspension device to one or more flaps with or without curved recesses. Construction element turbine arms and turbine discs contribute their surface area parallel to the power conversion duct extent, for further structuring of the kinetic ocean energy. Each turbine arm or other suspension device, can have one or preferably several elastic or inelastic flaps which can be single, double or multiply. In the open position sliding the flaps in the sea slim surface formations or hydrodynamic against any flow that is different from the turbine rotation speed and direction at the moment. The part of sea mass moving coinciding with the rotational direction and faster than flap turbines rotational speed in the area that the force affecting the flaps surfaces, will immediately cause the closing and strike the working phase where a large area in front of the turbine arms picks up momentum. Often, several rows of flaps on the same turbine work together and provide a greater overall pressure surface that operates turbines and generate desired final energy. The flaps may be divided into suitable lengths and widths as the entire turbine crossection extent not necessarily activated. Sometimes there will be only a few flaps closing, other times several turbine surfaces will close simultaneously. An increasing number of narrower flaps along a turbinarm or suspension device, prolongs the working phase, the intermediate phase is shorter. Wide and narrow flaps react as quickly to changes in sea mass movements and pressure conditions, but flaps hiking path becomes shorter narrower than broad flaps. The hydrodynamic resistance in the interval may increase somewhat for flap turbines with many narrow flaps. The flaps may also be double and multiply with the same number or a different number of flaps on either side of the opening and closing axis. Flap widths and design in general can vary in one or more planes. For example, flaps outer rim be sinusoidal and double or multiply flaps may be partially phase shifted in relation to each other to make the opening of the flaps lighter in the intermediate phase. There may be provided different distance bodies between or next to one or more flaps to effect flap
movement in the desired direction and to provide flaps hydrodynamic shape in the rest phase and to contribute to rapid induction of the intermediate phase and the transition to the working phase. Distance pieces may be elastic and partly be pressured slightly together by flaps at rest phase to the intermediate phase is initiated when the flaps are pushed apart and spread out to either side. Work phase begins with increasing wave activity, tidal and ocean current which coincides with flap turbine rotation speed and flaps work phases.
Direction of rotation for each turbine can be coincident or opposite of the way neighboring turbines rotate. Flap wheels to a complete standstill may have flaps that occupies a rest position which differs slightly from tangential position. The flaps can complete standstill form a small angle with the tangent through the flap suspension point so that the flap points slightly inward towards flap turbine's center.
Often rotational directions being organized in groups for turbine location in the plant. Only waters with movement directions and speeds that affects one or more flaps, will transfer kinetic ocean energy or kinetic energy during the primary energy conversion. For major energy deposits powers would cause the flaps are pressed and bent into its curved support fields turbine arms, pendulum arms or turbine discs with grooves for flaps movements. The elastic flaps saves this way kinetic energy as potential energy under the sea as part of the primary energy conversion, for the next phase to release accumulated potential energy to further rotation of the turbine at the extension of working phase duration and work road length. Deeper curvature with increasing instances of kinetic ocean energy increases the flap structural strength and ability to withstand the increasing loads. Storing various force components of potential energy also helps to equalize the differences in the force components that affect a flap turbine.
Continuous activation of the pressure surfaces in the form of flaps which alternates between working phase and the resting phase, the total amount to several times the area of wavelength and power station extension. That is the difference between the pressure on the front and back of the flaps that determine the performance together with the duration.
Some flap turbines can be constructed without support for centrally located turbine core or center shaft. It can in many cases be appropriate to use a plurality of flap
turbines without tubular core or center shaft because such structures to some extent interfere the motion cycles to the kinetic ocean energy. The sea mass' complex motion cycles can thus relatively undisturbed pass center area during stepwise primary energy conversion where a plurality of flap turbines included. A self- supporting turbine design can be built up in many different ways to withstand alternating dynamic forces during continuous rotation. This type of flap turbines may for example have different longitudinal band structures inside and outside the center area. These can be prestressed between the turbine side or the power plant modules. Flap wheels can have one or more annular support means connecting turbine arms in the same plane of rotation. Furthermore, inner and outer spiral band and X-band included in the construction of a building. Construction elements as turbine discs and center discs are parallel to power modules and may extend into the center region although flaps not necessarily being directed towards the central part of the turbine. Flap wheels may have pendulum arms with corresponding flaps that described for the turbine arms.
A pendulum is preferably eccentrically mounted on the turbine arm with more than half its length on the inside of the turning point. In this design solution has turbine arms do not necessarily own direct mounted flaps. During the working phase, a rocker estimated change their angle of 30-90 degrees relative to the rotating turbinarm. Shuttle arms can also be used on flap turbines turbine cores and concentric turbines that rotate inside the other. Water masses speedup just outside a closed turbine core will often give the biggest pendulum movements. During the working phase moving pendulum arms more parallel to the water mass movement and can increase flap turbines' rotation speed by momentum components against inner and longest part of the rocker arm or vector arm causes the outer part of the arm moves in the opposite direction. All pendulum arms can for example be connected to X-band forming a cylindrical support structure parallel to flap turbine's extent. Eccentric rotary support of the rocker arm against turbine arm can stretch out the X-bands of the person or pages that flaps in the working phase. This would both save additional kinetic energy as potential energy and extend the working phase and the intermediate phase help to bring the rocker arm back into its initial position in the rest phase.
Since power volumes in kinetic ocean energy varies very much in all waters, it is necessary that many flap turbines participating in the stepwise energy conversion . It is a prerequisite for achieving high efficiency both at small and large energy resources. A larger number of flap turbines boosts total capacity and more energy from tidal waves and currents can be converted while production is raised to a higher level during periods of large deposits of wave energy. All the time, the energy level for each of the three forms of kinetic ocean energy higher inside the power conversion channels
At high energy deposits all flap turbines increase their rotational speeds during the primary energy conversion and transfer performance of further secondary energy conversion that can produce the desired final energy until full installed capacity. It will mainly be such that all three forms of kinetic ocean energy in the joint energy conversion, but in some periods only some sequences coincide selected direction and speed. There are times, however many days where ocean waves alone accounts for the entire power plant's energy production because of wave motion speed and energy far exceeds motion velocities of tidal wave and currents even in periods when the latter two flow directions coincide.
In principle flap turbines be mounted in many different ways. For example, the turbines being mounted between three smaller wheels forming a 120 degree angle to each other. The wheels may be mounted on shafts that simultaneously transmit the rotating mechanical energy of preferably large wheels on either side of a flap turbine for further energy conversion inside the power plant modules. Concentric flap turbines can be supported in the same manner with the corresponding transmission where turbines that rotate inside the other is paired with intermediate wheels and axles. In addition, many other possible structural solutions for the support of the flap turbines and further transfer of energy either turbines with or without a core or external support. Such energy transfer can also be hydraulically or pneumatically. Occupied concentric flap turbines may further have direct induction where mounting an induction means can be between fixed and rotating areas of the modules and turbines, or in various ways exploit the double speed difference between the shorter parts of a turbine which rotates in opposite directions.

Structuring kinetic ocean energy and increase movement speed:
Sea mass will increase its speed of movement on either side of and between the structures in the ocean. If more vertical lines power plant modules is parallel close to each other in the sea, sea mass' movements in the area between power modules will increase their movement speed mainly in a vertical plane parallel to the power plant modules. Turbine circuits or other structures used in connecting power modules, will further contribute to such acceleration. We can say that have the energy or the performance in terms of sea masses moving beyond offshore power plant "urgent" in from the front and the corresponding forces or momentum in the area on the aft side creates "pressure". This means that the power plant utilizes ocean energy from surrounding areas well beyond energy plant extent. The areas' total kinetic energy recovery therefore far better and offshore
power plants occupy less space in the sea for each MW and GW who converted to another performance.
Change in direction or structuring of sea waves agitating movements takes place predominantly in two different forms of deflection caused by power plant construction and operation. Power plant modules and module legs causes diffraction as waves characteristic change of direction around an object sticking up in the ocean. The overall power plant with flap turbines causing refraction or deflection due to the change of velocity corresponding waves change in direction if they are approaching a beach area with some angle. As previously mentioned, diffraction and refraction provide a total deflection of about 90 degrees. Furthermore, structuring of the kinetic energy takes place by means of turbine disks and turbine arms with sufficient flat areas parallel to the power module's lateral surfaces, may further be mounted energy structuring units preferably front flap turbines. These are made up of numerous parallel and vertical lines surfaces. In this way a greater degree of structuring of the kinetic energy in directions that increase the hydrodynamic force directly against the flap turbine flaps in the working phase.
The sea mass' movement speeds increase and range of motion is extended in all directions inside the power plant as a result of energy structuring, permanent and adjustable "compression" of the three forms of kinetic ocean energy. The energy content increases to the square of sea mass' new motion speeds. Power plant The terminal's structural thickness on each side of the power conversion channels represent a lateral constriction in ocean energy moving through power conversion channel and thereby increases the water mass movement speed and motion as the lengths. A number of horizontal lines turbine cores represents a hill tract narrowing in power conversion channel. This helps to reinforce this effect and achieved a further increase in movement speed and lengths of motion.
All types of power plant modules included in the structuring of the kinetic ocean energy to have their motion as parallel as possible with the module vertical plane straight toward flap turbines. The first turbines will be driven by the momentum components with the greatest speed. Step reduction in power component inequality will provide more uniform sizes with lower speeds longer inside and down the energy plant. Powerful tidal activity will mostly affect the front flap turbines unless the wave activity movement speed exceeds the flow rate. Calmer currents and tidal activity will
mainly affect the rear flap turbines with remaining ocean energy. Mass transport is constantly elevated inside the power conversion channels.
A larger number of large turbine discs preferably on the front flap turbines, will help to increase the structuring of the kinetic ocean energy to increase their range of motion in vertical directions, parallel to the modules and perpendicular to the flaps. The turbines may also be divided into smaller units between lateral surfaces fixed to the turbine core. Turbine segments on each side of such surfaces can for example have the opposite direction of rotation and with power transmission between turbine segments by radially opplagrete wheels inside the fixed surface. Alternatively, these segments have individual transmissions that are mechanical, hydraulic, pneumatic or have direct induction. Front one or more turbines may be mounted a suitable number of parallel surfaces next to each other to achieve or enhance the same energy structuring effect.
A thousand of year 8700 hours includes sea too little energy and some one thousand hours dominates ocean waves with problematic large and looming energy quantities. In many ocean areas offshore power plant according to the invention therefore designed so that the energy content can be increased by adjustable constriction inside the power conversion channels where higher energy levels channeled to a limited part of the flap turbines. A power module can have an outer movable walls which are vertical hinge or elastic attached along its front vertical edge inside the power conversion channel. The rear part of the "energy gates' can have means for adjusting the width way opening for the kinetic ocean energy against, for example the central part of the flap turbines. Such adjustable constriction will increase wave height and flow rate. If both side surfaces inside the power conversion channel has such a movable wall, the wave height and the flow speed in situations with very low deposits of maritime energy, increased to the 3 to 5 fold. This means that the energy level 9-doubled or increased to 25 fold higher level in the width and depth as the movable wall the opening or passage decide. This energy is led directly into the central portion of a plurality of flap turbines which can have one or more large turbine surfaces which obstruct the energies to expand laterally before the passage of one or more flap turbines. Such gates or walls may also be constructed in such a way that they can correctly closed under extreme conditions. The adjustable transverse wall will in such a context effect wave reflection.
Transmission and further energy conversion:
It can be used many different types of energy transfer further from the flap turbine primary energy conversion toward the kind of end energy is desired. The performance can be transferred in the form of mechanical, hydraulic or pneumatic energy to the appropriate location of the forward energy conversion on the inside or on the power plant modules or outside the plant. The power plant achieves highest efficiency if the primary and secondary energy conversion and energy transport between these functions is effective and adequate for end energy nature. Such a solution is that the flap turbine having so-called direct induction by induction means is integrated in the turbine discs and the turbine segments preferably rotate in opposite directions or where there is independent induction washers disposed between the turbine segments. Induction means may be localized to the module walls and rotating induction field or slices on the turbines. A similar solution is the direct transfer of rotational mechanical energy from the turbines flap through module wall to electrical generator inside these basic designs. It can be placed gearing means on one or both sides of the module walls. The generators represent in this case the secondary energy conversion eventually energy.
This could be asynchronous generator of 100 kW at 600 r / min to be felt electricity prodcution to about 250 kW at 1500 rev / min. It is gen- erally one or more generators on each side av klaffturbin one, and wherein the at principle can be " boat axels " through the powerplant module wall that transfers the mechanical energy from the flap turbine via a gearing system to the energy produceing units. It can also be used 2- speed generators. Further, a Antall generators or other energy producing units for stepwise connected by increasing instances av kinetic ocean energy. This gives great Opportunities to production increase by increasing the waveheight as the energy of sea waves will be felt by the square av waveheight.
By energy transfer in the form of hydraulic or pneumatic performance are respectively hydraulic motor and turbine, which will form the secondary energy conversion and the electrical generators are tertiary energy conversion eventually energy. Generally, the individual energy conversion represents considerable energy loss in addition to the performance lost during energy transforming spared between these devices.
Wave Reflective throughput wall inside the offshore power plant :
It can be mounted one or more transversalstilte reflection walls for residual waves between power modules. Wall means can be tight or have sufficient number of openings for the flow of tides and currents. It will often be appropriate to install such a wall device within the turbine area in the more central part of the power plant. Some plants may have two such wall means to allow for offshore aquaculture preferably in the middle part of the plant. The waves reflected by the wall means and can be included in constructive interference with other residual waves and return as amplified wave back to the turbine area. These interference waves will now participate in energy production also on the way out of the plant. The reflected waves can also form so-called destructive resonance, where incoming residual waves and reflected waves is reduced in size or offset. The openings on such a flow wall must be adjusted tides and currents in the relevant waters or sea area.
Wave Reflection Walls or throughput walls may have about seven advantageous features and applications of the power plant according to the present invention : a. wave reflecting function to increase efficiency ; b. structural function and significance of the primary power modules ; c. structural importance for secondary and tertiary modules ; d. be included in the foundation of wind turbines of the power plant modules ; e. important protection of centrally located farms ; f. framing and construction of offshore aquaculture ; and g. be included in the suspension of the construction elements in the Venturi pump upwelling of nutrient rich sea mass from deeper areas
Energy storage and alternative uses of surplus production. During the course of the year will be many periods where energy production, mainly because of wave activity may constitute a much higher capacity than the submarine cables are dimensioned or electricity grid need at the moment. Storing surplus energy can for example take the form of compressed air or other form of energy storage, inside the lower part of the power module's leg or other part of the "ship modules ". A number of air compressors, or other types of end -producing devices,
can automatically connect when the energy content of the ocean waves is increasing and approaching generator the maximum performance or earlier if the various reasons need to use storage or alternative use.
This is both an efficient utilization of energy resources and the existing structures and technical installations. The physical phenomenon that air temperature decreases during decompression in connection with the execution of gas turbines, can be compensated for by use of circulating seawater or waters that are heated during periods of surplus production of energy.
The cavity in each power plant module may as previously mentioned be used for engine over several floors and can accommodate a larger number of generators, control systems and gearing system, and equipment for other forms of energy conversion and storage. The power plant can also accommodate energy-intensive activities such as hydrogen production and cold storage activities related to offshore aquaculture. If it is necessary to reduce the biggest wave activity further, the installed capacity of the plant is increased to a much higher total capacity. This can be done by increasing the number of flap turbines and energy-producing units and consider larger turbines, shuttle turbines, double and triple concentric turbines with and without pendulum arms. The possibilities for storage and alternative uses of surplus production must be increased accordingly.
Tidal and storm surge grounding and protection of power and flap turbines :
Offshore power plant base construction, power modules and devices for connecting these, and flap turbines, supplied alternating tidal levels and moves up and down along with that part of the ocean waves that are too big and too infrequently occurring that it is economically profitable to let them be part of the energy conversion.
For this reason, the power plant is preferably built up of long and relatively slender power modules with a number of module legs which are connected one or several different types of tidal and tidal wave ancherings. The anchor means to allow the desired vertical level change while limiting the power plant movement in other directions.
The power plant module bones can on the aft side or front preferably be connected to anchor arm by link element or elastic means. In anchorage other end is this similarly connected anchor member fixedly mounted on the seabed. It is mainly anchorage length and movement that determines the power plant's ability to vertical movements. Anchorage length must be assessed in relation to the areas' maximum tidal variations and wave heights. Anchoring arm can be resiliently movable in one or more planes and may have attenuator to forces necessitating changes of anchorage length. The opposite side of the power plant may preferably have more traditional anchor chain with attached solder elements. Offshore power plant can thus move in different directions under high external pressure. If the plant's front and rear side are arranged in parallel working anchorage arms, the power modules maintain its horizontal position during height directional movements.
Some waters have developed a special shaped power module with anchoring device only at one end of an elongated modular bone that has link element or elastic means directly connected to an anchor element. Modules can preferably have a buoyancy device at the top to ensure that the power plant following tidal changes and large undulations. It is further developed power modules with floods of the largest waves and therefore only to a limited extent follows the largest wave heights that are included in the measurement of the significant wave height in the relevant waters. Variants of the so-called submarine networks can be included in anchoring the plant or make all mooring. Such networks can simultaneously protect plant and flap turbines against smaller boats operating or off course, and floating objects in the ocean. Netconstruction can be stretched out from the more horizontal cable between the modules above or below sea level. Similar solutions can be used in the lower end of the net and in different ways be connected to the anchor elements in combination with docking solutions as previously described.
In some waters may be in the upper part of the ocean be necessary to protect flap turbines by mounting an energy structuring unit at the inlet to power conversion channel. These devices are made up of vertical parallel plates adjacent to each other and can also be equipped with network device with a mesh size adapted for local challenges.
Floating power plant anchored to the underwater energy plants.
In some waters may be advantageous to pair a bottom-anchored power to a floating facility using tidal and storm surge anchoring between the two energy plants. The size and mass of the floating power plant can in this way be reduced, making it easier for the plant to follow the major undulations.
Particularly in areas with high tidal energy can be beneficial to transform kinetic ocean energy further down into the ocean. Under huge wave activity, the fixed lower energy plant increasingly participate in the reshaping of the exponentially increasing amount of energy. The largest amounts of energy will still be in the upper ocean. Such facilities may also be beneficial in waters where it is necessary to convert the transition waves (transitional waves) to waves having shorter wavelengths and less energy down to the seabed to reduce the displacements of sediment. Constant and problematic changes of seabed in shallower waters due over passing waves' powerful horizontal back and forth movements in the depths. If water depth is increasingly less than a quarter of the wavelength, the undercurrents against the seabed be marked and creating major challenges for anchoring unless wave heights reduced by comprehensive energy conversion where both floating and fixed mounted power plants participate with all their capacity. This can be a big problem which hampers the anchoring of all types of installations at sea, not just the presented sea power plants.
By converting a substantial proportion of the sea waves kinetic energy is reduced transition waves or " transitional waves" to a regular wave that does not reach down to the sea bed even in shallow water. Combination of a lower and fixed power plants with anchoring means to an upper liquid energy facilities are particularly beneficial in waters with high kinetic energy deposits and large tide differences.
Synergistic combinations and other integrated solutions.
A power station according to the invention may be included in a variety of synergistic combinations with other energy systems based on renewable energy sources, and also permit the integration of many additional solutions. For example, energy islands and energy bridges utilize several different renewable energy sources, such as kinetic ocean energy, wind energy, ocean thermal energy (OTEC) and solar., As well as various forms of energy storage and alternative uses
of surplus production. Furthermore, the combinations include aquaculture and port facilities. It will often be a prerequisite for the survival and activity of such construction that they can transform the kinetic energy of the sea area. Flap wheels around a energy islandand under the inlet to a port or passageway for shipping, will reshape much of the kinetic energy and create calmer waters. Previously described tidal and storm surge anchoring can be used both for energy bridges and energy islands.
Power stations have extensively in an ocean. The need for sjokabling lapses throughout the plant insofar as energy plant has internal wiring through turbine cores or other longitudinal structural structures. If energy is developed as a peninsula or a jumper will all wiring follow the power plant constructions.

Flap turbines may have ties compounds 15 which keeps constellation together. Figure 33 shows a flap turbine as seen from the front has a convex shape. Flap turbine has turbine discs 9 with cutouts for the radial lines and elastic double flaps 4 and four double flaps 5. The flaps are mounted along the edge of the cut-outs in the turbine discs 9. Flap turbine has outer X-band 14 throughout the turbine extent and X-bands are preferably secured all turbine discs 9. In the rest phase is flaps hidden within turbine plate thickness and in the working phase curves flaps backwards. The kinetic ocean energy's power components will force the flaps further backwards and open for passage in the center between the flaps between two turbine discs. The flaps have anything beyond curvature in its bias faster to initiate work phase. Turbine discs can have cutouts for several radial Asked flaps off each other, or just have carvings for a variety of flap trubine's flaps. All types flap turbines front view having a tapered, convex, concave or cylindrical shape in its axial extent.
Figure 34 shows a flap turbine as seen from the front has a convex shape. The flap turbine has radial Asked elastic flaps 3 off each other between the turbine discs 8. Flap turbine has longitudinal turbine arms 7 with curvature 7a flaps bend in the working phase. Flap turbine has inner X-band 13 that connects the turbine discs 8. Flap turbine may have outer X-band and / or inner center tape and center disk.
Figure 35 shows an example of the stress-absorbing connecting power modules 17 where between the turbine cores and connecting means 6 and the power modules 17 is arranged an elastic material 6b. It drafted pairing can also be used without stress absorbing material. Yokes connecting means 6a extends further into the modules than ordinary connecting means 6. By controlled projecting the elongated connecting means 6a might be possible disengagement of the shorter turbine cores 6. Flap turbines without cores held in place by the three wheels 24 for supporting and transmission. Fixation 27 of the anchoring device is preferably in the lower part of the power modules 17 and, respectively, fore and aft.
Figure 36 shows a power station which is built up of five flap turbines that are held together by three tubes 15 which rotates over the closed engine disk 8. The turbine
disk 8 provides the necessary buoyancy. Outer rim of the turbine surface 8b may be gummed or have gear ring and roll towards each other with opposite directions of rotation. The turbine discs do not rotate in the direction of stretch tape has flywheel plates 8c. Transmission and generator 25 is located inside the triangular generator housing 25a. Flap turbines have resilient leaves 3 which is secured to the turbine arms 7 with curved recess 7a for blades bend in the working phase. Flap turbines may also have fixed connecting means, for example between the turbine plate's center areas or between the turbine plate's outer rim.
Figure 37 shows a flap turbine approximating opens and closes after the " umbrella principle ". The turbine has long turbine arms 7 as extremely having a permanently fixed or movable hexagonal structure 7d. Each of the sides of the hexagon 7d constitute a transverse pivot axis for each of the double flaps 4 which may be elastic or rigid. The flaps 4 have longitudinal axis of rotation or elastic support between the two halves of the flaps. Flap turbine engages the three integrated forms of kinetic ocean energy and converts water masses complex and varying kinetic energy into rotation by selectable torque at this primary energy conversion.
