Preferably, the Sonnenstandsnachdreheinheit is intended to be a

Photovoltaic system trained power generation unit to align a sun. An alignment with the sun can be done both by a clock and season, as well as by means of a sensor. When using a sensor in particular an unnecessary twisting, such as in bad weather, can be avoided. As a result, an automatic Sonnenstandsnachdrehung be enabled. Preferably, such an advantageous high efficiency of the power generation unit can be achieved.

It is further proposed that the Sonnenstandsnachdreheinheit to a

Furthermore, a reliable rotation can be made possible. In addition, can be dispensed with additional drive units to a Sonnenstandsnachdrehung.

It is further proposed that the tubes of the at least one buoyant platform each have at least three pins, which are integral with a

By "in one piece" should be understood in particular to be at least materially bonded, for example by a welding process, an adhesive process, an injection process and / or another process that appears expedient to a person skilled in the art, and / or advantageously shaped in one piece, for example by a Manufacture from a single mold and / or by manufacture in a single or

Multi-component injection molding and advantageously from a single blank. By a suitable attachment wear can be kept advantageously low. Furthermore, in particular a fastening possibility can be created, which preferably remains unaffected by temperature-induced changes in length of the tube. In addition, in particular a fastening possibility can be created, which preferably remains unaffected by the instability of the buoyant platform. In addition, it is proposed that the support structure, which is at least partially attached to the fastening elements, at least partially consists of trapezoidal profiles. Preferably, the trapezoidal profiles are designed as Regelstahltrapezprofile. In this context, a "trapezoidal profile" is to be understood as meaning, in particular, a profile which, viewed in a sectional plane perpendicular to a longitudinal extent, has an at least approximately trapezoidal cross section When viewed along the longitudinal extension, three inner edges adjoining each other have two facing inner angles between in each case two of the main edges, in each case more than 90 ° and particularly preferably less than 170 °. The trapezoidal profile, viewed in a sectional plane perpendicular to a longitudinal extent, preferably has an at least approximately trapezoidal cross-section that is open towards one side i sides of a trapezoid. In principle, it would be conceivable that at least one of the main edges consists of an edge averaged out of several short edges. By using trapezoidal profiles can advantageously be provided a profile which absorbs high normal forces and low torsional stresses. In this way, a soft carrier structure, in particular without the use of wearing parts, can be provided.

It is also proposed that the at least one buoyant platform has a breakwater device in an outer edge region, with at least one structural element arranged below a water surface, which is provided for a deceleration of a shaft. Preferably, the at least one structural element of the breakwater device is arranged at a defined depth below the water level. Preferably, the at least one breakwater device reduces the wave action in the direction of a geometric center of the platform. Advantageously, the at least one breakwater device reduces the wave action in that direction to the defined value which is less than 80% of a wave output, more preferably less than 60% of the wave output, and most preferably less than 30% of the wave output. A "wave breaking device" is to be understood in this context, in particular a device provided for this purpose is to reduce a wave effect within the outer edge region to a defined value. Preferably, a wave effect is reduced by breaking the wave to a defined value. In this context, a "wave effect" is to be understood as meaning, in particular, a change in a bearing surface of the platform caused by a wave and thus a change in a position of the energy-generating units

Sea water surface. Furthermore, in this context under a

In this context, a "macroscopic surface structure" is to be understood in particular to mean a surface structure which has elevations and / or depressions that extend beyond a basic shape of a body. Preferably, the elevations and / or depressions have a height and / or depth, in particular perpendicular to a surface of the basic shape of a body, of at least 0.1 cm,

preferably at least 1 cm, preferably at least 2 cm and more preferably at least 5 cm. A "defined depth" is to be understood as meaning, in particular, an average distance between a longitudinal axis of the wave absorption element and the water level which is the result of the payload A "wave output effect" is to be understood in particular as a wave effect which precedes hitting the platform, ie a multi-sided Outer edge of the

Platform, present. By the breakwater device, a region, such as the outer edge region, can be provided on a sea, in which there is a smaller wave effect compared to the open sea. This can provide a safe stand for the power generation units on the sea, which allows the sea location with its advantages, such as the huge usable areas, can be used for energy.

Furthermore, it is proposed that the at least one structural element of

Breaking device is designed as a trapezoidal sheet. As a result, in particular a particularly stable structural element can be provided. Furthermore, this can reliably reduce a wave effect at least. In particular, an advantageous deceleration of a shaft can thereby be achieved under one

Water surface can be reached, so that a wave excited to overturn becomes. In principle, however, would also differ from a trapezoidal sheet

Design of the structural element conceivable. There are various, a person skilled in the appearing reasonable formations of the structural element conceivable, such as a corrugated iron. It is further proposed that the breakwater device has at least one first structural element, which is arranged in an outer outer edge region, and has at least one second structural element, which is arranged opposite the first structural element at a substantially lower depth below a water surface and arranged in an inner outer edge region is. Preferably, the structural elements are at least approximately identical. In a direction from a sea-side outer edge of the platform in the direction of the geometric

Center of the platform considered, the inner outer edge region preferably follows directly on the outer outer edge region. Preferably, the inner outer edge region, viewed in a main extension plane of the platform, surrounded by the outer outer edge region. The outer outer edge region preferably directly adjoins the sea-side outer edge. In this context, a "substantially smaller depth" should be understood in particular to mean that a value of an averaged depth of the at least one second structural element is at most 80%, preferably at most 65% and particularly preferably at most 50% of a value of an averaged depth of the at least one first structural element This makes a particularly reliable one

Wave effect at least be reduced. Preferably, in particular, an advantageous delay of one already by the at least one first

Structural element broken, smaller wave can be achieved under a water surface. So can advantageously be broken even small waves. It is further proposed that at least a part of the tubes of the at least one buoyant platform is designed as a semi-sinker, and a part of

Breaking device which forms at least one buoyant platform. In this context, a "half-sinker" is to be understood as meaning in particular a buoyant body whose total volume in an intended state is at least 50%, preferably at least 60%, preferably at least 70% and particularly preferably at least 80% lower than an acting load Water surface is pressed. This can be advantageously prevented that waves burn against the pipes. Preferably, it can thus be achieved in particular that waves overflow the tubes and are delayed in the overflow due to the friction on an upper side of the tube. Furthermore, the invention is based on a method for operating a platform device. It is proposed that the at least one buoyant platform is rotated via the sun position turning unit at least partially relative to a position of the sun by means of the at least one anchoring unit. As a result, an automatic Sonnenstandsnachdrehung be enabled. Preferably, such an advantageous high efficiency of the power generation unit can be achieved. Furthermore, a reliable rotation of the at least one buoyant platform can be made possible.

Furthermore, it is proposed that the breakwater device, at least in an outer edge region of the buoyant platform, a delay of the

Platform device causing waves. By the breakwater device, a region, such as the outer edge region, can be provided on a sea, in which there is a smaller wave effect compared to the open sea. This can provide a safe stand for the power generation units on the sea, which allows the sea location with its advantages, such as the huge usable areas, can be used for energy.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS In FIGS. 1 to 13, an exemplary embodiment of a device according to the invention is shown

Platform device 10 shown. In the figure 1, the entire platform device 10 is shown schematically in a plan view. The platform device 10 is arranged on a sea 70. The platform device 10 is anchored at a distance of more than 70 km from a coast on a seabed 72. In principle, however, another distance to a coast, which appears appropriate to a person skilled in the art, would also be conceivable. In principle, the platform device 10 can be anchored both near the coast or in international waters irrespective of water depths. Preference is given to destinations with an annual solar radiation of more than 2000

Hours of sunshine. The platform device 10 has a square shape in this embodiment. In principle, however, another form that would appear meaningful to a person skilled in the art would also be conceivable, for example a round or triangular shape. The platform device 10 generates regenerative energy. The platform device 10 is formed as an anchored swimming platform. The platform device 10 is designed as an anchored solar swimming platform.

The platform device 10 has a buoyant platform 12. The platform 12 is intended to carry a power generation unit 14 above a water level 16. The power generation unit 14 forms part of the platform device 10. The platform 12 covers a part of a support surface

Sea water surface. The platform 12 has an edge length of about 1000 m. In principle, however, another edge length which would appear meaningful to a person skilled in the art would also be conceivable. However, edge lengths of 1000 m to 2000 m are preferred. For supply and disposal, the platform device 10 has a harbor 74. The port 74 is realized by a free seawater surface within the platform 12. The port 74 is located in a center of the platform 12. To achieve the port 74, the platform device 10 has an access channel 76 which extends from an outer edge of the platform 12 to the port 74. The access channel 76 is also realized by a free seawater surface within the platform 12. In the harbor 74 is a submarine cable 78 with an associated

Power conditioning. The submarine cable 78 is not visible with the

Energy generating unit 14 connected. The submarine cable 78 is provided for transmission of electrical power to a coastline transfer station. The submarine cable 78 extends below a water level 16, preferably at least near one

Meergrunds 72. There are also 74 staff accommodations 80 in the port, as well as docking berths for boats and / or ships not further visible.

The power generation unit 14 is formed as a regenerative power generation unit. The power generation unit 14 has a photovoltaic system 82. Furthermore, the energy generating unit 14 has a wind power plant 84. However, it would also be conceivable that the power generation unit 14 only one

Photovoltaic system 82, only one wind turbine 84 and / or others, one

Professional appears as meaningful power generation plants, in particular regenerative power generation plants, has. The photovoltaic system 82 and the wind turbine 84 of the power generation unit 14 are mutually partially complementary, ie, the photovoltaic system 82 and the wind turbine 84 complement each other in part. The photovoltaic system 82 has a multiplicity of photovoltaic modules 86. The photovoltaic modules 86 are each elevated by an elevation 88 on the platform 12. The elevation 88 is essentially composed of L-profiles. The elevation 88 is also held between two L-profiles, which on one

Carrier structure 20 of the platform 12 are attached. The L-profiles extend parallel to tubes 18 of the platform 12. The photovoltaic modules 86 have a nano-coating on one surface. Furthermore, the photovoltaic modules 86 are each composed of several individual modules. The individual modules preferably have a size of 1.956 m to 0.941 m. The photovoltaic modules 86 each have a size of 9.75 m to 8.46 m. In principle, however, other sizes would be conceivable. An optimum angle of inclination of the photovoltaic modules 86 is site specific (Figure 8, 12).

The photovoltaic system 82 also has a cooling unit 144. The

Cooling unit 144 pumps to a cooling of the photovoltaic modules 86 seawater from a practicable depth in a tube 146 which extends at an upper end horizontally on an upper edge of the photovoltaic modules 86. For pumping the seawater, the cooling unit 144 has a submersible pump with a CU sieve. The horizontally extending portion of the tube 146 has a lower borehole above each bead. A size of the holes is chosen so that at the beginning and at the end of the tube 146 at least approximately the same amount of water leaks. The emerging from the lower boreholes water flows under the photovoltaic modules 86 along. It arises through

Evaporation cold, whereby the photovoltaic modules 86 are cooled because of the favorable convection. As soon as the first electricity is generated in the morning, the

Pumping capacity increased so that sea water in addition to the lower boreholes also also emerges from upper boreholes in the tube 146 and injected onto the photovoltaic modules 86. Thus, the photovoltaic modules 86 can be cleaned every day. In addition, the cooling unit 144 can also be used for cleaning (FIGS. 8, 13).

In addition, a not visible bird control is provided. Because if between the tubes 18 of the platform 12 juvenile fish feel particularly well, especially by vegetation, deep water of the cooling unit 144, oxygen by dripping

Cooling water, shading through the modules and fresh seawater through a

Turn, also seabirds will come. Although these may basically take place anywhere on the platform device 10, but not on the power generation unit 14. Especially because the best cleaning system, the excrement, when dried, can not rinse off. It is therefore necessary on the topmost tube 146 of the

Cooling unit 144 to install an electric wire. In principle, however, would also be another, a professional appear appropriate sense bird control conceivable, such as a pigeon-guard barbed wire.

There are destinations where not only a lot of sunny days, but also wind> 8,0 m / s / a can be found. Because to a geometric center of the platform 12 no

significant seaway is more, the wind turbine 84 can be installed there regardless of the sea depth. The wind turbine 84 has a plurality of wind wheels 90. The windmills 90 are placed between the photovoltaic modules 86 of the photovoltaic system 82 on the platform 12. The wind wheels 90 are set up in such a way that a shadow falls in each case in a region free of photovoltaic modules 86 (FIG. 1).

As a rule, there is essentially no wind in sunshine and therefore cloud-free sky and thus the photovoltaic system 82 generates energy and when the sky is cloudy and thus substantially absent sunshine, the wind turbine 84 generates energy, the platform device 10 usually produces regenerative energy continuously. The photovoltaic system 82 and the wind turbine 84 are thus complementary to each other. Since there is enough space on the sea 70, the platform device 10 can be arranged in any number so that large undulating surfaces arise. These can be used as harbors, for electricity storage (P.to.G. storage), for tourism, for fish farms, for desalination plants, etc. Outside territorial waters, countries can produce PV power, e.g. to gas, even if these countries have no sea access, e.g. Switzerland, Austria etc.

The buoyant platform 12 includes a plurality of buoyancy providing tubes 18. Furthermore, the platform 12 has a support structure 20, which is attached to the tubes 18. The tubes 18 are each formed as a PP tube. The pipes 18 have a guaranteed service life of 100 years. The tubes 18 are each formed as a polypropylene tube. The tubes 18 are each arranged parallel to each other. The tubes 18 are each distributed in several over the entire platform 12, over the entire Platform 12 extending rows arranged. The tubes 18 of a row are each welded together. In addition, in each case a safety bulkhead 92 is welded into a connection region between the tubes 18 of a row. The safety bulkheads 92 are cup-shaped. About the safety bulkhead 92 each of the inner cavities 94 of adjacent tubes 18 are separated from each other. One

Welding of the tubes 18 during assembly of a platform 12 is usually carried out on the coast, in particular according to specifications of the PP pipe manufacturer. However, it would also be conceivable that the tubes 18 are welded, for example, on a ship (Figure 8, 1 1). The tubes 18 of the buoyant platform 12 each have four pins 46, 46 ', 46 ", 46"' on. Furthermore, the tubes 18 each have a hollow cylindrical base body 48. The base bodies 48 each form a basic shape of the tube 18. The four pins 46, 46 ', 46 ", 46"' of a tube 18 are formed integrally with the base body 48 of the tube 18. The four pins 46, 46 ', 46 ", 46"' of a tube 18 are respectively to the

Base 48 of the corresponding tube 18 is extruded. The pins 46, 46 ', 46 ", 46"' respectively protrude in the radial direction from the base body 48 of the corresponding tube 18. The pins 46, 46 ', 46 ", 46"' are each on a peripheral surface of the main body 48 of the corresponding Pipe 18 is arranged. Further, the pins 46, 46 ', 46 ", 46"', viewed in a circumferential direction of the main body 48 of the corresponding pipe 18, are evenly distributed on a peripheral surface of the main body 48 of the corresponding pipe 18. The four pins 46, 46 ', 46 ", 46"' of a tube 18 are provided for receiving fasteners 50, 50 ', 50 ", 50"'. By means of the pins 46, 46 ', 46 ", 46"', fastening elements 50, 50 ', 50 ", 50"' can be fastened to the corresponding tube 18. The fasteners 50, 50 ', 50 ", 50"' can be attached to the pins 46, 46 ', 46 ", 46"' for this purpose. For this purpose, the fastening elements 50, 50 ', 50 ", 50"' are each fastened between two pins 46, 46 ', 46 ", 46"' adjoining one another in the circumferential direction. The fasteners 50, 50 ', 50 ", 50"' are respectively screwed through the pins 46, 46 ', 46 ", 46"'. The fastening elements 50, 50 ', 50 ", 50"' in each case form a connecting part between the tubes 18 and load entries, in particular the support structure 20. The fastening elements 50, 50 ', 50 ", 50"' are each made of regular shaped parts made of galvanized steel educated. Four of the fasteners 50, 50 ', 50 ", 50"' each form a group, each on a pipe 18 in Radial direction forms an eight-sided cladding. The four fastening elements 50, 50 ', 50 ", 50"' of a tube 18 form an enclosure of the tube 18, which has eight flat outer surfaces in the radial direction. The outer surfaces completely surround the tube 18 in the region of the fastening elements 50, 50 ', 50 ", 50"'. successive

Outer surfaces of the fastening elements 50, 50 ', 50 ", 50"' are tilted in the circumferential direction in each case at 45 ° to each other. In this case, the carrier structure 20 can be advantageously placed on this eight-sided enclosure. An upper outer surface of a group of

Fasteners 50, 50 ', 50 ", 50"' are each aligned horizontally. The

Carrier structure 20 is usually in an assembled state of three adjacent outer surfaces of the groups of fasteners 50, 50 ', 50 ", 50"' at. The support structure 20 generally rests, and is secured to, the three upwardly facing outer surfaces of the groups of fasteners 50, 50 ', 50 ", 50"' in an assembled condition (Figures 8, 10).

The support structure 20, which is partially attached to the fasteners 50, 50 ', 50 ", 50"', consists partly of trapezoidal profiles 52. By a structure of

Carrier structure 20 can get service boats 162 at almost any point of the platform 12 below the power generation unit 14. The support structure 20 is essentially constructed of trapezoidal profiles 52. The trapezoidal profiles 52 of the support structure 20 are made of hot-dip galvanized steel. The trapezoidal profiles 52 therefore have a guaranteed service life of 50 years. The trapezoidal profiles 52 of the support structure 20 have an identical cross section. The trapezoidal profiles 52 differ only in one length. The trapezoidal profiles 52 have a constant length along a longitudinal extent

Cross-section on. A cross section of the trapezoidal profiles 52 is described below by way of example on one of the trapezoidal profiles 52. However, a description can also be applied to the other trapezoidal profiles 52 (FIG. 8).

The trapezoidal profile 52 has, viewed in a sectional plane perpendicular to a longitudinal extent, an approximately trapezoidal cross-section. The trapezoidal profile 52 has an open cross section. The trapezoidal profile 52 has, viewed in the sectional plane perpendicular to a longitudinal extent, three mutually adjoining main webs 96, 98, 100. The main webs 96, 98, 100 of the trapezoidal profile 52 are each integrally connected to each other. The main webs 96, 98, 100 are bent in one piece. One middle main web 98 is connected to the other two main webs 96, 100. Two facing inner angles 102, 104 between the central main web 98 and one of the two other main webs 96, 100 are each more than 90 ° and less than 170 °. The inner angles 102, 104 are each about 1 10 °. The two inner angles 102, 104 are identical. At the middle of the main web 98 facing away from the two other main webs 96, 100 each have an outwardly directed approximately L-shaped end web 106, 108 is arranged. The

End webs 106, 108 each connect at an angle of approximately 1 10 ° to one of the two further main webs 96, 100, so that the end webs 106, 108 extend at least approximately parallel to the central main web 98. The

End webs 106, 108 are each integrally connected to one of the two other main webs 96, 100. The ends of the end webs 106, 108 are each with a further main webs 96, 100 facing inner angle of approximately 1 10 °

angled. The central main web 98 has in a central region an increase 1 10. Between the increase 1 10 and the other main webs 96, 100 is formed on both sides of the increase 1 10 each have a channel 1 12, 1 12 ', which serves to receive supply lines 1 14, 1 14' (Figure 8, 9 ).

The support structure 20 also has no further visible cross connections between the trapezoidal profiles 52, which are intended to prevent a carrier tilting. In addition, the not visible cross connections serve as horizontal stiffeners. The cross connections are used in part to secure the risers 88 of the photovoltaic modules 86.

Furthermore, the platform device 10 has a first anchoring unit 22 fixedly connected to the buoyant platform 12. Furthermore, the

Platform device 10 has a second anchoring unit 26 fixedly connected to the buoyant platform 12. The first anchoring unit 22 and the second anchoring unit 26 are respectively disposed on opposite sides of the port 74 on the platform 12. The first anchoring unit 22 and the second

Anchoring unit 26 are respectively disposed in the vicinity of the port 74. The first anchoring unit 22 and the second anchoring unit 26 are each closer to a geometric center of the platform 12 than to the outer edge area 54 arranged. Furthermore, the first anchoring unit 22 is formed symmetrically to the second anchoring unit 26 with respect to a plane passing through the geometric center of the platform 12 at least in a basic position. The first anchoring unit 22 is connected to the second anchoring unit 26 with respect to the geometric center of the platform 12 at least in one

Basic position formed point-symmetrical (Figure 1).

The first anchoring unit 22 has three anchor windings 24, 24 ', 24 ". The second anchoring unit 26 also has three windlasses 28, 28', 28". In principle, however, other numbers of armature winches 24, 24 ', 24 ", 28, 28', 28" which appear appropriate to a person skilled in the art would also be conceivable. The anchoring units 22, 26 are identical. The anchoring units 22, 26 have only a mirrored arrangement to each other. The anchoring units 22, 26 are described below with reference to the first anchoring unit 22. A description of the first

Anchoring unit 22 can in principle also be applied to the second anchoring unit 22 (FIGS. 1, 5).

The anchor winches 24, 24 ', 24 "of the first anchoring unit 22 are each in

Anchor windings 1 16, 1 16 ', 1 16 "of the anchoring unit 22. The windlasses 24, 24', 24" are each a turntable in the

Anchor winders 1 16, 1 16 ', 1 16 "The armature winches 24, 24', 24" of the first anchoring unit 22 are rotatably mounted relative to the buoyant platform 12. The armature winches 24, 24 ', 24 "are respectively rotatably mounted relative to the platform 12 about an axis of rotation 1 18. The axes of rotation 118 of the armature winches 24, 24', 24" extend through a center of the corresponding windlass 24, 24 ', The axes of rotation 1 18 are rotatably mounted perpendicular to a main extension plane of the platform 12. The armature windings 1 16, 1 16 ', 1 16 "are arranged side by side in a row and connected via connecting beams. Each of the

Anchor windings 1 16, 1 16 ', 1 16 "are each arranged exactly between two tubes 18. The armature windings 1 16, 1 16', 1 16" have a square basic shape. The first armature wind receiver 1 16 adjoins the second armature wind receiver 1 16 'with one side. The three other sides border the

Anchor wind receiver 1 16 to one pontoon each 120, 120 ', 120 "The three pontoons 120, 120 ', 120 "are each designed as a concrete pontoon The pontoons 120, 120', 120" each consist of seawater-resistant, glass fiber reinforced concrete cubes, which are filled at safety-relevant places with closed-pore foam. The three pontoons 120, 120 ', 120 "each have a payload of about 300 t, but in principle another payload would also be conceivable. The armature wind receiver 1 16 is connected via connecting beams to the three pontoons 120, 120', 120". The third

Anchor wind receiver 1 16 "adjoins the second armature wind receiver 1 16 'with one side, the armature wind receiver 1 16" adjoins the pontoons 122, 122', 122 "with the three further sides "are each designed as a concrete pontoon. The pontoons 122, 122 ', 122 "each consist of

Seawater-resistant, glass-fiber reinforced concrete cubes filled with closed-cell foam at safety-relevant points. The three pontoons 122, 122 ', 122 "each have a payload of about 300 t, but in principle another payload would also be conceivable. The third armature wind receiver 1 16" is over

Connecting beams connected to the three pontoons 122, 122 ', 122 "The pontoons 120, 120', 120", 122, 122 ', 122 "of the anchoring unit 22 provide for the

Anchoring unit 22 a buoyancy ready. The vertical forces are thereby absorbed by the buoyancy of the pontoons 120, 120 ', 120 ", 122, 122', 122", the horizontal forces are entered by tie rods in the working plane. Since the platform 12,

in particular through the tubes 18, is designed as a semi-sinker, therefore, the displacement of the tubes 18 is just so designed for the platform 12 and the power generation unit 14, via the pontoons 120, 120 ', 120 ", 122, 122', 122" in addition acting forces, such as anchoring forces are intercepted.

In principle, it would also be conceivable to provide further pontoons which receive, for example, rotational forces, a submarine cable intake, landing quays, the personnel accommodations 80 and / or power conditioning devices (FIG. 5).

The three anchor winches 24, 24 ', 24 "of the first anchoring unit 22 are connected to three spatially separated anchor points 30, 32, 34. Each of the anchor winches 24, 24', 24" is connected to one anchor point 30, 32, 34 each , The first windlass 24 is connected to a north anchor point 30. The second windlass 24 'is connected to a western anchor point 32. Further, the third windlass 24 "is connected to a south anchor point 34. The three windlasses 28, 28 ', 28 "of the second anchoring unit 26 are likewise connected to three spatially separated anchor points 30, 34, 36. Each of the anchor winders 28, 28', 28" is connected to one anchor point 30, 34, 36 each. The first windlass 28 of the second anchoring unit 26 is connected to the south anchor point 34. The second windlass 28 'is connected to an eastern anchor point 36. Furthermore, the third windlass 28 "of the second anchoring unit 26 is connected to the north anchor point 30. The north anchor point 30 and the south anchor point 34 are therefore connected to two windlasses 24, 24", 28, 28 "respectively ', 24 "of the first anchoring unit 22 and the windlasses 28, 28', 28" of the second anchoring unit 26 are each a spring steel strip 38, 38 ', 38 ", 40, 40', 40" with the anchor points 30, 32, 34th The spring steel bands 38, 38 ', 38 ", 40, 40', 40" each have a rectangular cross-section with a dimension of 2.5 mm x 600 mm A required damping of the spring steel bands 38, 38 ', 38 ", 40, 40 ', 40" is given in the horizontal alignment of the cross section of the spring steel bands 38, 38', 38 ", 40, 40 ', 40", since the spring steel bands 38, 38', 38 ", 40, 40 ' , 40 "with varying traction more or less sag and this Durchhängemaß under water only very slowly än can (Figure 1, 2).

The three anchor windings 24, 24 ', 24 "of the first anchoring unit 22 and the three windlasses 28, 28', 28" of the second anchoring unit 26 are constructed identically. The armature winches 24, 24 ', 24 ", 28, 28', 28" are described below by way of example with reference to the first windlass 24 of the first anchoring unit 22. A

Description of the first windlass 24 of the first anchoring unit 22 can in principle also be applied to the further windlasses 24 ', 24 ", 28, 28', 28" (FIG. 5). The first windlass 24 of the first anchoring unit 22 has an escape wheel 42. On the escape wheel 42 of the windlass 24, the spring steel strip 38 can be wound up. By winding or unwinding the spring steel strip 38 on the escape wheel 42, a distance between the windlass 24 and the anchor point 30 can be changed. The escape wheel 42 has a width of a tread, which corresponds approximately to a width of the spring steel strip 38. So a uniform rolling and unrolling can be made possible. The escape wheel 42 has a diameter of 5 m. By a big one Diameter of the escape wheel 42 can be kept low on the escape wheel 42 in particular even with a large working length of the spring steel strip 38 an order. Thus, a take-up of the spring steel strip 38 on the escape wheel 42, at a

Working length of the spring steel strip 38 of 300 m, a thickness of about 100 mm. The escape wheel 42 is drivable via a drive unit 124 of the windlass 24. The

Drive unit 124 is designed as an electric motor. The drive unit 124 has a drive gear, which meshes with a ring gear of the escape wheel 42. An axis of the drive unit 124 is offset from an axis of the escape wheel 42. As a result, advantageously a translation between the drive unit 124 and the escape wheel 42 can be achieved. The escape wheel 42 is received rotatably mounted in a base 126 of the windlass 24. The drive unit 124 is firmly connected to the main body 126. The main body 126 has a horizontal bearing ring 128, via which the windlass 24 is mounted in the turntable of the armature wind receiver 1 16. Furthermore, the base body 126 has two mutually parallel fixed to the bearing ring 128 connected walls 130, 130 '. The walls 130, 130 'are vertically aligned. The escape wheel 42 is partially disposed between the walls 130, 130 '. Further, a deflection roller 132 is disposed between the walls 130, 130 '. The deflection roller 132 is arranged approximately at the level of a lower edge of the pontoons 120, 120 ', 120 "The deflection roller 132 is provided for guiding the spring steel strip 38. Via the deflection roller 132, a collision of the spring steel strip 38 with the pontoons 120, 120' can take place. , 120 "or parts of the platform 12 are prevented. Between the guide roller 132 and the escape wheel 42 is a

Belt cleaning unit 134 arranged. The belt cleaning unit 134 is also disposed between the walls 130, 130 '. The spring steel strip 38 is guided between the deflection roller 132 and the escape wheel 42 through the belt cleaning unit 134. About the belt cleaning unit 134, the spring steel strip 38 is cleaned before winding on the escape wheel 42. Thus, for example, shells or algae can be wiped off on the escape wheel 42 before winding up the spring steel strip 38. Furthermore, the windlass 24 has a brake 136. The brake 136 is provided to block the escape wheel 42. Via the brake 136, the escape wheel 42 can be stopped or held in its current position in a state not driven by the drive unit 124. The windlass 24 is partially covered by a housing 138. The housing 138 is arranged on the armature wind receiver 1 16. The enclosure 138 is intended. The windlass 24 to protect from the weather (Figure 6, 7).

Furthermore, the platform device 10 has a sunshade turning unit 44. The Sonnenstandsnachdreheinheit 44 is formed as a computing unit. The

Sunroom spin unit 44 is arranged here in the port 74 for quick and easy accessibility, by way of example. The Sonnenstandsnachdreheinheit 44 is at a partial Sonnenstandsnachdrehung the buoyant platform 12th

intended. The position of the sun-visor turning unit 44 is provided for rotating the buoyant platform 12 to actuate the armature winches 24, 24 ', 24 ", 28, 28', 28" of the first and second anchoring units 22, 26. To a

Sonnenstandsnachdrehung the Sonnenstandsnachdreehenheit 44 is provided to drive the drive units 124 of the windlasses 24, 24 ', 24 ", 28, 28', 28" separately and in each case by targeted winding or unwinding of the spring steel strips 38, 38 ', 38 ", 40, 40 ', 40 "to achieve a twisting of the platform 12. This allows a rotation of 120 °. The platform 12 can therefore be aligned from morning 8.00 clock to afternoon 16.00 clock to the sun. The rotation takes place in the example with a force of 100 tons per anchoring unit 22, 26, which must be added in addition to the anchor forces. Since a rotation is very slow, in the example 300 m spring steel strip 38, 38 ', 38 ", 40, 40', 40", which must be wound up and unwound in 8.0 hours, this can be done with a comparatively small power , The required power for twisting is less than 1% of a through the

Power generation unit 14 generated power. At a water depth of more than 300 m, it would also be conceivable to realize the reverse rotation from the 16.00 o'clock position to the 8.00 o'clock position by means of a weight raised during the day, for example per 100 t. Thus, a reverse rotation in particular without energy input from land could take place overnight (FIGS. 1, 2).

Since the platform 12 aligns with the position of the sun, the shadow of the

Windräder 90 always in the same place, so no in this area

Photovoltaic modules 86 are mounted. 2, the platform 12 is shown in three different rotational positions with three different positions of the sun 164, 164 ', 164 ", wherein the platform 12 is shown only schematically in the individual rotational positions, a first position of the sun 164 corresponds to an 8 o'clock rotational position of the platform 12 In this rotational position, the platform 12 is shown in phantom, and a second position of the sun 164 'corresponds to a 12 o'clock rotational position of the platform 12. In this rotational position, the platform 12 is shown by a solid line the platform 12. In this rotational position, the platform 12 is shown by a solid dash-and-dot line. The buoyant platform 12 is rotated about the Sonnenstandsnachdreheinheit 44 partially relative to a position of the sun by means of anchoring units 22, 26.

The buoyant platform 12 has in an outer edge region 54 a

Breaking device 56 on. The breakwater device 56 has a plurality of structural elements 60, 62 arranged below a water surface 58. The structural elements 60, 62 are arranged parallel to the main extension plane of the platform 12. The

Structural elements 60, 62 of the breakwater device 56 are each formed as a trapezoidal sheet. The structural elements 60, 62 are distributed over an outer region 54. Furthermore, the structural elements 60, 62 are provided for a deceleration of a shaft. The structural elements 60, 62 are provided for delaying waves striking the platform 12. The structural elements 60, 62 are mounted on the support structure 20 of the platform 12. The breakwater device 56 has several first structural elements 60. The first structural elements 60 are in an outer

Outside edge region 64 is arranged. The first structural elements 60 are arranged offset from one another in a plane parallel to a main extension plane of the platform 12. Furthermore, the breakwater device 56 has a plurality of second structural elements 62. The second structural elements 62 are arranged in an inner outer edge region 68. The second structural elements 62 are arranged offset in a plane parallel to a main extension plane of the platform 12 to each other. The second structural elements 62 are arranged opposite the first structural elements 60 at a substantially lower depth 66 below a water surface 58. The first

Structural elements 60 are arranged at a depth 140 of approximately 2.5 m. By contrast, the second structural elements 62 are arranged at a depth 66 of approximately 1.0 m. waves are therefore delayed by the first structural elements 60 in the outer peripheral edge region 64 below and are thus excited to roll over. In the next phase in the inner outer edge region 68, the new smaller waves, which have arisen from the large waves, are again delayed by the second structural elements 62 and broken again. The breakwater device 56 causes in an outer edge region 54 of the buoyant platform 12 a delay of waves striking the platform device 10 (FIGS. 3, 4).

Further, a portion of the tubes 18 of the buoyant platform 12 forms part of the breakwater 56 of the buoyant platform 12. The tubes 18 located in the outer edge area 54 form part of the breakwater 56.

This results in the outer edge region 54, which consists of the outer outer edge portion 64 and the inner outer edge portion 68, a wave pattern that does not affect the platform 12. After about 100 m, measured from an outer edge of the platform 12, only an insignificant sea state is encountered, so that all parts, such as the pontoons 120, 120 ', 120 ", 122, 122', 122", the submarine cable 78, etc can be measured without waves. Rare big waves will continue to generate waves inward, but do no damage, as the platform 12 passes through

Carrier structure 20 offers little resistance and lets these rare big waves through easily. The seaworthiness is guaranteed up to a wave height of 14.0 m. In addition, the platform 12 has a Treibgutabweiser 142 in the outer edge region 54 at an outermost edge. The Treibgutabweiser 142 is formed as a water-permeable, in particular perforated, sheet metal, which is arranged at the level of the water level 16. The Treibgutabweiser 142 is disposed at a height of the tubes 18. In principle, however, would be another, a professional appears appropriate training, such as a network, conceivable. The Treibgutabweiser 142 is vertically attached to the support structure 20. The Treibgutabweiser 142 is disposed all around at the edge of the platform 12. By the Treibgutabweiser 142 is an intrusion of

Flotsam be prevented (Figure 3, 4). The spring steel strips 38, 38 ', 38 ", 40, 40', 40" are fixed to the anchor points 30, 32, 34, 36 in each case via a basic anchorage 148 a on the seabed 72. A

Design of the basic anchoring 148a is dependent on one

Sea bottom condition, a water depth as well as environmental requirements. The

Basic anchoring 148a in this embodiment comprises a plurality of precast concrete parts 150a, 150a ', 150a ". The basic anchoring 148a is particularly large

Water depths useful. The precast concrete parts 150a, 150a ', 150a "each have an integrated tube 152a, 152a', 152a", in which the corresponding spring steel strip 38, 38 ', 38 ", 40, 40', 40" can each be guided. The pipe 152a, 152a ', 152a "is formed as a PP pipe 16. The precast concrete parts 150a, 150a', 150a" are each divisible and bolted so that the pipe 152a, 152a ', 152a "can be opened laterally For example, the spring steel strip 38, 38 ', 38 ", 40, 40', 40" can be threaded through the precast concrete part 150a, 150a ', 150a ", for example on a work boat, to the precast concrete part 150a, 150a', 150a" on the spring steel strip 38, 38 ', 38 ", 40, 40', 40" can be brought out along guided The precast concrete parts 150a, 150a ', 150a "of a

Anchor points 30, 32, 34, 36 are each positively and non-positively connected to each other. With a settlement of one of the anchor points 30, 32, 34, 36, the spring steel strip 38, 38 ', 38 ", 40, 40', 40" is lowered at a not visible end terminal at the intended location. On the spring steel strip 38, 38 ', 38 ", 40, 40', 40" are then the precast concrete parts 150a, 150a ', 150a "- as a string of pearls - lowered in a calculated number (Figure 14, 15, 16).

FIGS. 17 to 19 show two further embodiments of a basic anchoring of the invention. The following descriptions are limited in the

Substantially to the embodiments of the basic anchorage, with respect to the same components, features and functions on the description of the other embodiments, in particular the figures 1 to 16, can be referenced. In order to distinguish the exemplary embodiments, the letter a in the reference signs of the basic anchorage of the exemplary embodiment of FIGS. 1 to 16 is replaced by the letters b and c in the reference signs of the basic anchorage of the exemplary embodiments of FIGS. 17 to 19. With regard to the same named components, in particular with respect to components with the same reference numerals, in principle also to the drawings and / or the description of the other exemplary embodiments, in particular FIGS. 1 to 16, are referred to.

FIG. 17 shows an alternative basic anchoring 148b of the platform device 10. The spring steel bands 38, 38 ', 38 ", 40, 40', 40" are fixed to the anchorage points 30, 32, 34, 36 via the basic anchoring 148b on the seabed 72. The

Ground anchor 148b has an anchor block 154b. The anchor block 154b consists of IPE profiles. The anchor block 154b has a mask with an intended number of recesses. Each of the recesses guides and fixes anchor piles 156b in the intended length. The anchor piles 156b are formed as Larssenprofile. Larssen profiles are particularly useful for soft sediments. The spring steel bands 38, 38 ', 38 ", 40, 40', 40" are attached to the anchor block 154b via pivot joints 158b, 158b '. The anchor piles 156b are lowered into a seabed 72 via a shock or vibration ram equipped with a pressure-resistant encapsulation. The construction is chosen so that no underwater work is necessary. When one of the anchor points 30, 32, 34, 36 is lowered, a care line with which the spring steel strip 38, 38 ', 38 ", 40, 40', 40" can be pulled in and fastened to a docking buoy (FIG. 17, FIG. 18).
