The present invention relates to a solar-powered solar power generation device that is installed in a place covered with water, such as a reservoir, a reservoir, a fishpond, a lake, the sea, etc., to generate electric power. More specifically, it can be installed easily. while there, the installation state of the water installation solar power system as floating body about the water installation solar power equipment that allows so as not to impair the effect of wind and waves.

The above-water installed photovoltaic power generation device has a solar cell panel and is composed of a power generation float that floats on the water surface. The solar power generation apparatus for installation on water in Patent Document 1 below is an example thereof, and is configured by connecting a plurality of power generation floats (solar cell units) in a state in which the mutual fluctuations are allowed. The structure for connecting the power generation floats to each other uses an annular connecting ring. The connecting ring has a structure in which wire rods are wound in a coil shape in which the wires are closely packed. Such a connecting ring is attached between the corner portions of the power generation floats arranged vertically and horizontally with a gap so as to connect them.

In this connection structure, when the connection rings allow the power generation floats to swing with respect to each other, and when the power generation floats try to separate from each other, the connection ring is prevented from being pulled and separated from each other by a certain amount or more. The connecting ring, which is approaching, elastically abuts the opposing power generation floats to prevent the power generation floats from approaching each other more than a certain amount.

Each of the power generation floats moves relatively freely, preventing separation and approaching above a certain level. This makes it possible to follow the waves caused by strong winds and improve durability.

In addition, in the solar power generation device for installation on water of Patent Document 1, in order to complement the action of the above-described connection structure, a line extending in a grid pattern along the power generation float group is provided below the power generation float. Is moored by mooring means. The mooring means is composed of a fixing rope connected to the rope and an anchor connected to an end portion of the fixing rope. The anchor is fixed to the bottom of the water and cooperates with the fixing rope to hold the grid-shaped rope in a grid shape.

To achieve the intended purpose of the grid-shaped rope, the anchor must be firmly fixed so that it does not move.

In order to firmly fix the anchor, it is necessary to drive the anchor deep into the bottom of the water, construct an anchor structure on the bottom of the water, and perform large-scale construction. For this reason, it was not easy to install a solar power generation device for water installation. In addition, considering the removal work of the solar power generation device for installation on the water and the subsequent process, it is desirable to install the solar power generation device with a configuration as simple as possible.

The present invention relates to a floating photovoltaic mooring apparatus for mooring a floating body such as a floating solar mooring apparatus and a floating photovoltaic mooring apparatus, such as the floating floating mooring apparatus. The description of the mooring device used for the above is replaced with the description.

FIG. 1 is a plan view showing an installation state of a solar power generation system 11 installed on water (hereinafter referred to as “water surface generation device”), FIG. 2 is an enlarged view of a part of FIG. 1, and FIG. 3 is a side view thereof. As shown in these figures, the floating power generation device 11 is moored by the mooring device 12 to the water bottom 13 and is kept in a desired installation state floating on the water surface.

First, the main body portion of the floating power generation device 11 will be described, and then the mooring device 12 and other components will be sequentially described.

<Main part of floating generator>
The body part of the floating power generation device 11 is configured by connecting a plurality of power generation floats 11a as shown in FIG. 4 to each other. The power generation float 11a has a solar cell panel 15 on its upper surface and floats on the water surface.

The power generation float 11a has a rectangular plate-shaped float body 16 that floats on the water surface, and a panel mount 17 that is fixed to the upper surface of the float body 16 and on which the solar cell panel 15 is installed. FIG. 5 is a perspective view of the float body 16 during assembly. As shown in this figure, the float body 16 is formed by combining a plurality of foamed resin plates 21 with their end faces aligned to form a square. This is because the size of the float main body 16 cannot be covered by a ready-made foam resin plate, and when the size of the float main body 16 is small or a foam resin plate having a desired size can be manufactured, one plate material is used. It can also be configured with.

As the foamed resin plate 21, for example, one having a vertical width of 1 m×2 m is used, and a float main body having a size of, for example, 5 m×5 m is used. The thickness of the foamed resin plate 21 is appropriately selected depending on the weight and the number of the solar cell panels 15 used. The foamed resin plates 21 are joined together by an appropriate means such as an adhesive, if necessary. In the example of FIG. 5, a turnbuckle 22 stretched diagonally is provided on the bottom surface. In FIG. 5, reference numeral 23 is a fixing member for fixing the turnbuckle 22.

An auxiliary plate 24 for fixing members and a protective plate 25 for preventing deterioration are fixed on the upper surface of the float body 16. The auxiliary plate 24 is intended to join and integrate the plurality of foam resin plates 21 to be joined together, and contributes to fixing the panel mount 17 and the like, and is made of metal. The entire shape of the auxiliary plate 24 is a hollow plate shape having a narrow width corresponding to the length of one side of the float body 16, and has L-shaped edge portions 24a on both side edges along the longitudinal direction. A plurality of elongated holes 24b are formed on the upper surface of the auxiliary plate 24.

The protective plate 25 has a narrow plate shape and is made of an appropriate material having good weather resistance, particularly, UV resistance. For example, a calcium silicate plate can be preferably used as the material. The protection plate 25 is formed to have a length substantially corresponding to the length of one side of the float body 16, and the width dimension is set according to the installation location. This protective plate is laid on a portion exposed to sunlight when the solar cell panel 15 is installed on the upper surface of the float main body 16, and is appropriately formed large according to the arrangement of the solar cell panel 15.

Since the above-mentioned auxiliary plate 24 plays a role of fixing the panel mount 17, the protection plate 25 is arranged along with the auxiliary plate 24. Further, since the auxiliary plate 24 has the elongated hole 24b as described above, the protective plate 25 is also laid inside the auxiliary plate 24. FIG. 6 is a perspective view of a corner portion of the float main body 16 in a state where the auxiliary plate 24 and the protection plate 25 are laid, and FIG. 7 is a perspective view of an intermediate portion of one side.

FIG. 8 is a plan view of the float body 16 with the auxiliary plate 24 and the protective plate 25 laid. In the illustrated example, the auxiliary plates 24 are fixed to both side edges of the float main body 16 and two positions between them, a total of four positions, and the solar cell panels 15 can be installed in three rows along the auxiliary plates 24. The solar cell panel 15 is installed in a corresponding portion between the auxiliary plates 24 and blocks direct sunlight to a portion where the protective plate 25 is not laid.

Weather resistance to ultraviolet rays is also required for the side surface portion of the float body 16. Therefore, the side cover 26 as shown in FIG. 9 and the corner cover 27 as shown in FIG. 10 are attached. The side cover 26 is made of a weather-resistant aluminum alloy and has a U-shaped cross section. The height of the side surface cover 26 is a height corresponding to the height from the upper surface of the auxiliary plate 24 to the lower surface of the float main body 16. The length of the side cover 26 is set to be slightly shorter than the length of one side of the float body 16. The side cover 26 can also be used by adding a short one. The corner cover 27 is also made of a weather-resistant aluminum alloy, and has an angled shape in a plan view and an inverted L-shaped cross section. Since it is preferable that the corner cover 27 also plays the role of reinforcement, the corner cover 27 may be thicker than the side cover 26. The corner cover 27 is fixed by fixing the side cover 26 and then overlapping both ends of the corner cover 27 with the end of the side cover 26.

The panel mount 17 is fixed to the upper surface of the float body 16 configured as described above, as shown in FIG.

The panel pedestal 17 includes a pair of two long pedestal bases 31 extending in a direction orthogonal to the auxiliary plate 24, front legs 32 and rear legs 33 erected on the pedestal base 31, and these front legs. It has the receiving member 34 fixed on 32 and the rear leg 33, and receiving the solar cell panel 15. The gantry base 31 has a length substantially corresponding to the length of one side of the float body 16, and in the illustrated example, three sets, six in total, are arranged. Since the solar cell panels 15 are installed in three rows as described above, the front leg 32, the rear leg 33, and the receiving member 34 are arranged at equal intervals in three sets on the pedestal base 31. The front leg 32 is set shorter than the rear leg 33, and the receiving member 34 is inclined so that the front leg 32 side is lowered.

The gantry base 31, the front legs 32, the rear legs 33, and the receiving member 34 can be formed using an angle member. When an angle member is used for the gantry base 31 or the like, the direction of the angle member is set to be opposite on the other side as shown in FIG.

FIG. 12 is a side view of the panel mount 17. As shown in this figure, the panel mount 17 can adjust the inclination angle.

Specifically, the front legs 32 are erected at predetermined positions on the pedestal base 31, and the pair of front legs 32 are connected by diagonal members 35. The diagonal member 36 is also attached between the front leg 32 and the gantry base 31. The tip of the receiving member 34 is pivotally attached to the upper end of the front leg 32. The rear leg 33 that supports the rear end of the receiving member 34 includes a lower member 33a and an upper member 33b, and the lower member 33a is erected on the pedestal base 31. A diagonal member 37 is connected to the pair of lower members 33a as in the front legs 32 (see FIG. 13). Bolt holes 38a and 38b are formed at the upper end of the lower member 33a and at a position below it. These bolt holes 38a and 38b are used for fixing the lower end portion of the upper member 33b with a bolt 39 nut. An upper end of the upper member 33b is pivotally attached to a rear end of the receiving member 34, and the above-described bolt 39 is held in a bolt hole 40 formed at a lower end thereof.

The inclination angle of the receiving member 34 is set in advance, and when the bolt hole 40 at the lower end portion of the upper member 33b and the lower bolt hole 38b of the lower member 33a are aligned, for example, the inclination is 10 degrees, and the upper bolt hole 38a is aligned. When tilted, the inclination is, for example, 20 degrees. The inclination angle is set appropriately and is changed as needed according to the season and the place of installation.

Since the solar cell panel 15 is installed on the receiving member 34, when wind enters from the rear leg 33 side of the panel mount 17, a force for lifting the solar cell panel 15 acts. In order to prevent the floating due to this, it is advisable to attach a windbreak member 41 to the rear leg 33 as shown by a virtual line in FIG. 13 and as shown in FIG. The windbreak member 41 is made of an appropriate material such as a weather-resistant aluminum plate or tent canvas. It may be rigid or flexible as long as it can block the entry of a large amount of wind.

Although the panel mount 17 shown in FIG. 12 can change the tilt angle, it may have a constant tilt angle that cannot change the tilt angle as shown in FIG. Since it is not necessary to change the angle, the rear leg 33 is composed of one member, and the lower end of the rear leg 33 is fixed to the gantry base 31 and the upper end thereof to the receiving member 34. At this time, the rear leg 33 may be fixed in an inclined posture in which the lower end portion is lowered rearward and the upper end portion is inclined forward as shown in FIG. 15, for example. Assembling of the panel mount 17 is easy, and as shown by the phantom line in FIG. 15, it is possible to reduce the force by which the wind pushes the power generation float 11a when the windshield member 41 is attached. Because.

The power generation float 11a configured as described above floats on water due to the buoyancy of the float body 16, and the solar cell panel 15 exposed on the water surface receives sunlight to generate power. Even if the float body 16 receives sunlight, the protective plate 25, the side cover 26, and the corner cover 27 protect the foamed resin plate 21 inside from ultraviolet rays, so that high durability can be obtained. Since the corner cover 27 and the like protect the outer circumference of the float body 16 from the physical side as well, the durability can be improved also from this point. In addition, since the float of the float main body 16 is formed by the foamed resin plate 21, it cannot be used if there is a hole, and it is lightweight and easy to handle. Further, when the windshield member is attached to the panel mount 17, it is possible to suppress the solar cell panel 15 from being covered by the wind and the power generation float 11a provided with the solar cell panel 15 from being swept, and the above-mentioned water-based float 11a. It contributes to stabilizing the installation condition.

<Coupling device>
A plurality of the power generation floats 11a are connected to each other as described above to form the main body of the floating power generation apparatus 11. The structure for the connection, that is, the connection device 51 will be described below.

FIG. 16 is a plan view showing a part of a gap between four power generation floats 11a arranged vertically and horizontally in a grid pattern, and FIG. 17 is a plan view showing a connecting device 51 portion of one power generation float 11a. .. In these drawings, illustration of the solar cell panel 15 and the like is omitted, and a portion related to the coupling device 51 is mainly drawn.

As shown in these drawings, the coupling device 51 is provided at two locations on each side of the power generation float 11a and is fixed to the auxiliary plate 24 or the pedestal base 31.

As shown in FIGS. 18 and 19, the connecting device 51 (portion A in FIG. 17) fixed to the auxiliary plate 24 is composed of a connecting rod 52 and a fixing metal fitting 53.

The connecting rod 52 has a rotating end portion 52a that bends in one direction at both ends with a constant length, and has a rod body 54 and a rotating end member 55. The rod main body 54 is made of metal and has rigidity, and has pivot portions 54a at both ends with a constant length. The pivot portion 54a is formed in an annular shape having a through hole 54b at the center. The rod main body 54 is used such that the direction of the center line of the through hole 54b is orthogonal to the longitudinal direction of the rod main body 54 and is parallel to the upper surface of the power generation float 11a. The rotary end member 55 is made of metal and has a U-shape in a plan view, and has both ends thereof pivotally attached to the pivotal attachment portion 54a of the rod main body 54 with fasteners 54c through a fixing metal fitting 53 in an intermediate portion.

The fixing member 53 holds the rotating end 52a with the bending direction of the rotating end 52a of the connecting rod 52 in the thickness direction of the generating float 11a, and is fixed to the upper surface of the generating float 11a. The fixing fitting 53 is made of, for example, an angle member, and has a fixing piece 53a fixed to the auxiliary plate 24 on the upper surface of the power generation float 11a, and a standing piece 53b that rotatably holds the rotating end portion 52b of the connecting rod 52. .. A plurality of fixing holes 53c are formed in the fixing piece 53a, and the fixing pieces 53a are fixed with bolts and nuts using the elongated holes 24b of the auxiliary plate 24. A vertically long slot 53d is formed in the upright piece 53b, and the rotary end 52a is held in the slot 53d.

In the power generation floats 11a connected by such a connecting device 51, even if the power generation floats 11a try to separate from each other, the connecting rod 52 resists the pulling force and prevents the separation, and conversely, even if the power generation floats 11a try to approach each other. The connecting rod 52 is stretched to prevent it from approaching above a certain level. Since the rod body 54 of the connecting rod 52 is a rigid body, the spacing between the power generation floats 11a is kept substantially constant. On the other hand, as the rotating ends 52a at both ends of the connecting rod 52 rotate and the rotating ends 52a are held in the elongated holes 53d of the fixing bracket 53, as shown by the phantom line in FIG. Even if the floats 11a are connected to each other, they are relatively freely displaced in the vertical direction.

As shown in FIGS. 20 and 21, the connecting device 51 (part B in FIG. 17) fixed to the gantry base 31 is composed of a connecting rod 52 and an end of the gantry base 31 as a fixing metal fitting. ..

Since the structure of the connecting rod 52 is the same as that described above with reference to FIGS. 18 and 19, detailed description thereof will be omitted.

The fixing metal fitting is not separately provided as shown in FIGS. 18 and 19, but the rotary end 52a of the connecting rod 52 is held at the longitudinal end of the gantry base 31 as shown in FIG. An elongated hole 31d is formed to replace the fixing metal fitting 53 shown in FIGS.

By the connection by the connecting device 51 having such a configuration, the plurality of power generation floats 11a are displaced in the vertical direction flexibly with respect to the waves while the intervals between the plurality of power generation floats 11a hardly change. Therefore, the main body of the floating power generation device can flexibly absorb the load applied by the waves, and the plurality of power generation floats 11a are highly integrated.

The plurality of power generation floats 11a are connected according to the shape of the installation location and the like. The connection is performed by arranging the power generation floats 11a side by side vertically and horizontally, but as shown in FIG. 1, the power generation floats 11a are arranged in an appropriate shape not limited to a rectangular shape depending on the shape of the installed water surface, the condition of the sunlight, the desired amount of power generation, and the like. Since the connection device 51 connects the plurality of power generation floats 11a in a highly integrated state as described above, a solid connection state can be obtained regardless of the arrangement shape.

<Mooring device>
Next, the mooring device 12 mooring the main body of the floating power generator 11 will be described.

As shown in FIGS. 1, 2, and 3, the mooring device 61 includes a cord 62 extending from the main body of the floating power generation device 11 and an anchor 63 connected to the cord 62 and installed on the bottom 13 of the water. Composed.

A wire made of stainless steel, which has strength and opposition, is used for the cord 62.

As shown in FIG. 22, the anchor 63 includes a moving body 64 connected to the cord 62 and placed on the water bottom 13, and a holding body 65 that holds the moving body 64 on the water bottom 13 while allowing the movement. I have it. The moving body 64 is formed with a biting portion 66 that extends obliquely downward from the bottom surface of the moving body 64. The biting portion 66 is directed forward in the moving direction of the moving body 64.

Specifically, the moving body 64 has a rod shape and is movable in the longitudinal direction. The moving body 64 preferably has a shape that moves without changing its posture, and its bottom surface is preferably flat. Such a moving body can be formed using, for example, H steel. A connecting portion 67 to which the cord 62 is connected is formed above the one end side portion of the moving body 64 in the longitudinal direction. The connecting portion 67 may be formed by standing H steel or the like on the upper surface of the moving body 64. In FIG. 22, reference numeral 68 denotes a diagonal member that reinforces the connecting portion 67. A through hole 67a is formed at an appropriate position of the connecting portion 67 to allow the cord 62 to pass therethrough.

The above-mentioned biting portion 66 is formed at the end of the moving body 64 on the side where the connecting portion 67 is formed, that is, at one end in the longitudinal direction. The bite portion 66 is long in the direction orthogonal to the longitudinal direction of the moving body 64, and the middle of the longitudinal direction is joined to the moving body 64. Therefore, the moving body 64 having the biting portion 66 has a T-shape in plan view as a whole. From the lower end of the biting portion 66 moves of the same length as the biting portion 6 6 formed at the end of the 64 rectangular plate of the upright plate 69, and extends toward the longitudinal end direction diagonally below of the moving body 64 There is. A plurality of ribs 70 for holding the biting portion 66 are provided between the standing plate 69 and the biting portion 66. Further, both end portions in the longitudinal direction of the standing plate 69 are supported by diagonal members 71 extending obliquely from the moving body 64.

The inclination angle of the biting portion 66 is appropriately set depending on the situation of the water bottom 13 and the like, but is, for example, about 10 to 40 degrees, preferably about 30 to 20 degrees and about 25 degrees with respect to the longitudinal direction of the moving body 64. It is recommended to set the slope of.

The holding body 65 that holds the moving body 64 holds a part of the middle portion of the moving body 64 in the longitudinal direction so as to press the moving body 64 from above, and as shown in FIG. The screw anchors 72, the two connecting members 73 held on these screw anchors 72, the long holding frame 74 supported so as to span the connecting members 73, and the holding frame 74. A slide fitting 75 for movably holding the upper end portion of the moving body 64 is provided on the lower surface of the intermediate portion in the longitudinal direction.

That is, the holding body 65 is configured to movably hold the moving body 64 under the holding platform 74 that is installed above and away from the water bottom 13.

A well-known screw anchor 72 can be used, and the length and the thickness thereof are appropriately set according to the required fixing strength and the state of the water bottom. The connecting member 73 is formed of, for example, a square steel material, and forms a structure such as a bolt hole that is joined to the lower surface and the upper surface and is matched with the counterpart. The holding pedestal 74 has a flat surface at least on the lower surface, particularly in the middle portion in the longitudinal direction thereof, and can use, for example, channel steel as shown in the drawings or angle steel not shown. It is fixed to the connecting member 73 with bolts and nuts or the like. The slide metal fitting 75 is fixed to the lower surface of the holding frame 74, holds the upper flange 64a of H steel forming the moving body 64 with a gap, and is fixed by a bolt nut or the like.

Position of the holding member 65 with respect to the moving member 64 is a position where be moved to the side having the movable body 6 4 bite portion 66 does not come off from the holding member 65. Further, the length of the moving body 64 is set so that this is possible.

Such an anchor 63 is installed after the mud is removed from the bottom 13 of the water to make the moving body 64 in a flat state to the extent that it can move in the longitudinal direction. The installation is performed at a required position according to the arrangement of the power generation float 11a, and the cord 62 connected to the power generation float 1a is connected to the connecting portion 67 of the moving body 64. Further, at the time of installation, the moving body 64 is placed on the water bottom 13 with the biting portion 66 facing forward in the moving direction of the moving body 64, that is, in the direction in which the cord 62 extends, as described above.

As described above, the plurality of power generation floats 11a are connected to each other to form the main body of the hydroelectric power generation device 11. However, as shown in FIG. It suffices that the cord 62 connected to the anchor 63 is connected to a part of the power generation floats 11a.

The cord 62 is fixed to the power generation float 11a at both corners on the end side of the power generation float 11a as shown in FIG. 2, and an appropriate metal fitting is used by using the auxiliary plate 24 located on the upper surface of the corner. It is good to fix with.

When mooring, when the power generation floats 11a are arranged in a plurality of rows in the same manner as shown in FIGS. 1 and 2, it is preferable to collectively moor the moorings to one anchor 63. This is because the number of required anchors 63 can be reduced and the arrangement state of the power generation floats 11a can be easily maintained.

In order to moor a plurality of rows of the power generation floats 11a together, the cords 62 (62a) fixed to both corners of each power generation float 11a are gathered into one line as shown in FIG. (62b) is connected to the anchor 63 via the cord tension weight 77. The filament tension weight 77 plays a role of giving tension to the filament 62 and a role of maintaining a space between the power generation floats 11a arranged in a plurality of rows.

The cord tension weight 77 is composed of a long weight body close to the array length of the power generation floats 11a moored together. For this purpose, for example, H steel can be preferably used. A plurality of connecting holes (not shown) are provided on one flange of the H steel corresponding to the intervals of the previous ropes 62b, which is a collection of the ropes 62 extending from both corners of the power generation float 11a. On the other hand, the collected cord 62b is connected. A line 63c extending to the anchor 63 is connected to the middle of the other flange of the H steel in the longitudinal direction, and the tip of the line 63c is connected to the connecting portion 67 of the anchor 63.

When mooring is performed using the mooring device 12 in this manner, the rope 62 is pulled by the installation of the main body of the floating power generation device 11, as shown in FIG. Then, the moving body 64 moves in a direction having the biting portion 66 while being held by the holding body 65 on the water bottom 13, and with this movement, the biting portion 66 facing forward in the moving direction bites into the water bottom 13. By this bite, the moving body 64 is firmly fixed in position with respect to the water bottom 13.

The holding body 65 that holds the moving body 64 movably holds the moving body 64, and the moving body 64 itself bites into the water bottom 13 and is fixed by the traction force naturally generated. Compared with the case where a member that directly receives a pulling force is firmly fixed to the water bottom 13, a necessary holding force can be obtained by a simple fixing means such as the above-described known screw anchor 72.

The anchor 63 thus fixed in position cooperates with the cord tension weight 77 and the connecting device 51 to maintain the installed state of the main body of the floating power generation device 11.

As described above, the anchor 63 can be fixed by a small-scale and simple device such as the screw anchor 72, and the floating power generator 11 can be easily installed. Moreover, since it is not necessary to modify the water bottom 13 on a large scale, it can be easily installed and removed. It is easy to restore the original condition after removal.

<Swing resistor>
When the main body of the hydroelectric power generator 11 is moored by the mooring device 12 as described above, the anchor 63 is firmly fixed, the tension of the cords is maintained by the rod-shaped cord tension weights 77, and the spacing is maintained. Due to the windshield by the shelter member 41 and the flexible yet highly integrated connection by the connection device 51, the installation state can be maintained in a stable manner, but higher stability is obtained in the season when strong wind blows or in an area. Therefore, it is preferable to equip a part of the power generation float 11a with the swing resistor 81 as shown in FIG. 24, if necessary.

The swing resistor 81 has an opening 82a at the upper end, and a bottom bag-shaped bag body 82 in which an opening state of the opening 82a is maintained. The bag 82 is filled with water that floats the power generation float 11a.

The bag body 82 is formed of an appropriate material that does not easily allow water to pass through, and an annular shape-retaining wire 83 that maintains the open state is held at the opening edge that forms the opening 82a at the upper end. A suspending wire 84 for suspending is provided in the opening 82a, and an upper end of the suspending wire 84 is attached to a lower surface of the power generation float 11a or the like. The attachment may be performed using an appropriate metal fitting, or may be performed using the fixing metal fitting 23 (see FIG. 5) to which the turnbuckle 22 is fixed.

When providing such a swing resistor 81, generating a float 11a for oscillating resistor 81 generates the resistance in water it becomes difficult to move the water surface. As a result, the stability of the installed state of the power generation float 11a can be improved, and the load on the anchor 63 can be reduced. In other words, the fixing strength required to fix the moving body 64 of the anchor 63 can be reduced.

<Rack float>
Next, as shown in FIG. 1, the rack float 91 installed together with the main body of the floating power generator 11 will be described.

As described above, the main body portion of the submerged power generation device 11 can have a plurality of power generation floats 11a arranged in a free shape, and the number thereof can be increased as necessary. Therefore, the number of wirings increases. The rack float 91 is used to organize the wiring and improve the efficiency of maintenance of the power generation float 11a.

As shown in FIG. 1, the rack float 91 extends from the shore of the installation location toward the main body of the floating power generator 11, and is also installed in the main body of the floating power generator 11. The installation location of the rack float 91 is set appropriately according to need.

The rack float 91 is a part for extending the wiring and a passage for a person to walk. 25 is a perspective view of the rack float 91, and FIG. 26 is an exploded perspective view.

As shown in FIG. 26, the rack float 91 is provided on both sides of the cable rack 93, a rack rack 92 having a rectangular shape in a plan view, a cable rack 93 provided in the middle of the rack rack 92 in the width direction. It has a gallery 94.

The rack pedestal 92 includes a floating member 92b under a pedestal frame 92a made of a steel-like ladder. The floating member 92b has a thick rectangular plate shape, and a foamed resin plate may be used similarly to the power generation float. The rack base 92 is formed to have an appropriate length, and as shown in FIG. 25, is provided with an appropriate gap. The space between the rack bases 92 may be held by fixing the cable rack 93 and the corridor 94 provided above.

As the cable rack 93, a well-known cable rack may be used, and one having a roof 93a is used. A well-known one can be used as the gallery 94. Both the cable rack 93 and the corridor 94 are fixed by appropriate fixing means such as bolts and nuts.

The rack float 91 having such a configuration is floated at a desired position on the water and is also arranged between the power generation floats 11a as described above. When arranging between the power generation floats 11a, it may be connected to the power generation floats 11a by using the above-mentioned coupling device 51, if necessary. A highly integrated installation state can be obtained.

When the rack float 91 is provided, the electric wires can be easily handled when the floating power generator 11 is installed, and the workability of adjusting the inclination angle of the panel mount 17 and various maintenance is also improved.

Heretofore, one mode for carrying out the present invention has been described.

In the correspondence between the configuration of the present invention and the configuration of the above-described one embodiment,
The fixing metal fitting of the present invention corresponds to the above-mentioned fixing metal fitting 53 and the end portion of the gantry base 31,
The present invention is not limited to the above configuration, and other configurations can be adopted.

For example, two connecting devices may be provided on each side of the power generation float as described above, or three or more connecting devices may be provided.

Further, the moving body of the anchor is not limited to the one that moves in the linear direction, but it may move in other directions as well, and the biting part may have a plurality of things facing the same direction or a plurality of things facing different directions. You can also do it.

As the floating body moored by the mooring device, various types can be considered in addition to the solar power generation device. For example, there is a floating plant that generates energy using wind power or water flow.
