Description

  The present invention relates to a float configured to install a solar panel and a float assembly including such a float.

  In a solar power generation device that converts sunlight into electric power, a solar panel (also referred to as a solar cell panel or a solar cell module) is used as a photoelectric conversion device. Solar panels are mainly installed on the roofs, walls, and the ground of buildings, but in recent years they have also been installed on the water of idle ponds and lakes.

  When installing a solar panel on water, the float for floating a solar panel on water is used, and a solar panel is installed on a float (refer to patent documents 1 and 2).

JP-A-2014-511043 Unexamined-Japanese-Patent No. 2015-217771

(First point of view)
Such a float takes into consideration the influence of rain and the like and defines the solar panel in a prescribed direction (for example, the direction in which the panel surface is directed to the south in the northern hemisphere as in Japan: detailed in the second aspect) It needs to be designed so that it has enough buoyancy to face and keep it on the water. Conventionally, floats have been designed with a large margin for buoyancy, but making the floats larger has a problem that the manufacturing cost is increased. On the other hand, if the float is made smaller, the solar panel may not be stably held.

  In the first aspect of the present invention, a float is proposed in view of such circumstances, and a float which can be manufactured at a lower cost than before while maintaining the holding stability of a solar panel, and such a float To provide a float assembly including

(Second point of view)
The solar panel is implemented to incline the solar panel itself from the surface of the float to a predetermined end of the float itself in order to increase the power generation efficiency. For example, in Japan, it is normal to incline the normal of the solar panel to the south side of the zenith direction. However, the inclined panel is strongly affected by the wind from the back (lift), which may cause problems such as the solar panel coming off the rack and the rack itself being lifted. In particular, in the case of solar power generation for water use (where a solar panel is installed on a float for power generation), not only the solar panel is lifted (vertical force), but also the influence of horizontal movement is significant. The

  The second aspect of the present invention is proposed in view of such circumstances, and it is an object of the present invention to provide a float assembly including a float provided with a wind pressure countermeasure more suitable for use on water. Do.

(Third point of view)
The power generated by solar power generation through the solar panel is direct current. Since the power used for household power supplies is AC, a power conditioner (power conditioner) is required to convert DC to AC. Therefore, the power cable is connected between the power controller and the solar panel. In addition, if the power controller is installed on the float, it is necessary to transmit power from the power controller toward the land, so a power cable is also required. That is, one float assembly requires a large number of power cables, and these cables are disposed on the floats and around the passage joints connecting them, resulting in a problem of requiring a complicated configuration.

  In the 3rd viewpoint of this invention, it is proposed in view of such a situation, and it aims at providing the float aggregate which wiring of a power supply cable was arranged more.

FIG. 2 is a partial enlarged view of FIG. 1 and a schematic perspective view showing an elongated member 70. It is the elements on larger scale of FIG. 1, Comprising: It is a schematic perspective view which shows the windproof net 80. As shown in FIG. It is a sectional view showing two new floats 10a connected. FIG. 7 is a schematic perspective view showing the connection between the new-type float 10 a and the passage joint 60.

  Hereinafter, a float 10 (particularly, a new-type float 10a) according to an embodiment of the present invention and a float assembly 1 including the same will be described in detail with reference to the drawings.

1. Float Assembly FIG. 1 shows an example and a part of a float assembly 1, and a solar panel 50 is installed on a new float 10a, which is a float 10 formed as a molded plastic. On the other hand, the float 10 in which the solar panel 50 is not installed is the old type float 10b, and has a wider shape than the new type float 10a according to the present embodiment. Hereinafter, when the new and old are not distinguished, they are simply referred to as the float 10.

  The floats 10 are connected by a passage joint 60 (both old and new) formed as a plastic molding. Here, the passage joint 60 is connected to the float 10 at the upper surface of each float 10, and the floats 10 are connected at a predetermined distance in the connecting direction of the passage joint 60, thus a predetermined gap between adjacent floats 10 Is formed.

  On the other hand, the connection in the direction orthogonal to the connection direction by the passage joint 60 is performed by connecting the eave-shaped end portions of the floats 10. Since the eaves-like end is separated from the water surface when the float 10 is floated, a gap is formed between the floats 10 also in the relevant direction (direction orthogonal to the connecting direction by the passage joint 60). become. The two floats 10 (particularly, the new-type float 10a in this case) connected are characterized in that, as shown in FIG. With such a configuration, it is possible to disperse the load originally applied to one float 10 to the front and rear floats 10. Similarly, in connecting the float 10 and the passage joint 60, a part thereof is characterized by overlapping. With such a configuration, the load that would normally be applied to one path joint 60 can be distributed to the adjacent floats 10. In particular, it should be noted that such a distribution of force is important when a person walks on the passage joint 60. Note that, as shown in FIG. 12, in the connection area 18 in the overlapping state, the width or area of the overlapping area 18 a overlapping is larger than the width or area of the compression portion 19 used for fixing. Please keep in mind.

  In the float assembly 1 having the above configuration, in the predetermined coupling direction, the connection is made by the passage joint 60 formed as a plastic molded body, and the eaves of the float 10 are connected in the direction perpendicular thereto. And all intervals are kept constant (invariant). Therefore, the resistance to water is always kept small.

  Further, in the float assembly 1, they are connected by the passage joint 60, and the space between the floats 10 can be made large. By increasing the distance between the floats 10, the float assembly 1 becomes less susceptible to waves, and careless movement from the floating position can be prevented. In general, the float assembly 1 is provided with anchors or anchored to the land so as not to move by waves, and an anchor is provided to the mooring on the assumption of a high tide low tide difference and a change in water volume before and after rainy weather. Since the float assembly 1 has a large space between the floats 10, it is easy to receive the flow of water due to waves or the like and does not move carelessly.

  In addition, as described in the background art, the power generated by solar power generation through the solar panel is direct current, and the power used for household power sources is alternating current, so a power converter (DC) A power conditioner is required. In the float assembly 1 according to the present embodiment, as shown in FIG. 1, a power controller 72 is installed on the old float 10b as an example. Although not shown, the solar panel 50 and the power controller 72 are connected via a large number of power cables, and a power cable for transmitting power from the power controller 72 toward the land is also required.

2. Next, components of the float assembly 1 such as the new float 10a, the passage joint 60, and the solar panel 50 mounted on the new float 10a will be described in detail.

  2 to 6 are views showing a state in which the solar panel 50 is installed on the new type float 10a, and FIGS. 7 and 8 are views showing a state in which the solar panel 50 is removed from the new type float 10a. 9 and 10 are partially enlarged views of FIG.

  A plurality of floats 10 are connected by a passage joint 60 (see FIGS. 1 and 9) to form a float assembly 1 on which a solar panel 50 is installed. The float assembly 1 is a portion where, for example, several thousands (more than 10,000 in number) floats 10 gather, and in the floats 10 used for the float assembly 1, some floats 10 are used. The solar panel 50 is not installed, and it is a passage for performing maintenance inspection of the solar panel 50 (in this case, it is preferable to adopt the old type float 10 b). The aisle is also used to lay the cables from the solar panel 50.

  More specifically, as shown in FIG. 9, the floats 10 (for example, the new float 10a) adjacent to each other in the direction perpendicular to the front-rear direction of the float 10 are connected via the passage joint 60 at their respective ends. ing. Thus, a space 75 is created between the two floats 10 and the two passage joints 60 connecting them.

  Further, in the float assembly 1 according to the present embodiment, a plurality of elongated members 70 are provided so as to cross the space 75. As shown, it may be disposed between adjacent passage joints 60 or may be disposed between floats 10. For example, the elongated member 70 is, for example, a metal pipe having a U-shaped cross section. By arranging such an elongated member 70, it is possible to arrange the power supply cable in the space 75 which has conventionally been a dead space. It should be noted that the direction of arrangement of the power cable is as shown by the arrow in FIG. Of course, instead of the elongated member 70, a plate-like member may be disposed, but in view of cost and weight, such an embodiment is preferable.

  Since it is important for the float assembly 1 not to move due to the influence of wind or the like, the old float 10b has a configuration in which a mooring member such as an anchor rope can be moored. On the other hand, the new-type float 10a does not necessarily need this, and has a configuration in which a mooring member is omitted in the drawing. Generally, in order to moor the floats 10 related to the outer periphery of the float assembly 1, it is preferable to adopt the new float 10a as the float assembly 1 in the floats 10 other than the outer periphery.

  In particular, in order to prevent the influence of wind or the like, the float assembly 1 according to the present embodiment is provided with a windproof net 80 (an example of the “windproof member” in the claims). In particular, since the short side of the substantially rectangular new float 10a is designed to be shorter than the short side (or the corresponding side) of the old float 10b, it is possible to provide a windproof member for each new float 10a. Which is a cause of Therefore, the windproof net 80 according to the present embodiment is provided so as to extend from the support portion 11 of one new float 10a to the support portion 11 of the other new float 10a in two adjacent new floats 10a via the passage joint 60. Ingenuity is made.

  Further, by selecting the material of the windproof net 80, it is possible to adjust the suppression of the influence of the wind. Although the aperture ratio of the windproof net 80 differs depending on the material, for example, the aperture ratio is 0.01 to 0.5, preferably 0.05 to 0.4, and more preferably 0.1 to 0. .3. Specifically, for example, 0.01, 0.02, 0.03, 0.04, 0.05, 0.10, 0.15, 0.20, 0.35, 0.40, 0.45, It may be 0.50, and may be in the range between any two of the numerical values exemplified here.

  As shown in FIGS. 2 and 3, the new float 10a has a support 11 for supporting the front end 51 of the pair of longitudinal sides of the solar panel 50, and a rear end of the other longitudinal side of the solar panel 50. And a receiving portion 12 for receiving 52. Note that the height of the support portion 11 is the upper side from the surface wall 16 (see FIG. 7) so that the solar panel 50 is installed in an appropriate inclined state in consideration of the power generation efficiency of the solar panel 50. It protrudes in (an example of the "1st direction" in the range).

  An aluminum pedestal supported by the support portion 11 is provided at the front end portion 51 of the solar panel 50, and the pedestal is supported on the support portion 11. On the other hand, the new-type float 10 a includes a front side fixing bracket 13 for fixing the front end 51 side of the solar panel 50 to the support 11. Then, the solar panel 50 is fixed to the support 11 by being screwed to the fixing bracket 13.

  The rear end 52 of the solar panel 50 is also provided with an aluminum base similar to the aluminum base provided at the front end 51. The new float 10a includes two rear fixing brackets 14 for fixing the rear end 52 (rear side) of the solar panel 50 received by the receiving portion 12 to the new float 10a. The rear side of the solar panel 50 is fixed to the new float 10 a by the fixing bracket 14.

  The new-type float 10a is manufactured, for example, by blow molding in which a tubular parison in a molten state is sandwiched between a plurality of divided molds and is manufactured by blow molding, and various thermoplastic resins can be used for the molding material. Polyolefin resins such as polyethylene and polypropylene can be suitably used.

  As shown in FIGS. 7 and 8, the new float 10a has a substantially rectangular outer shape (rectangular shape) as a whole, and includes a side wall portion 15 including a parting line PL and a surface wall 16 located on the upper side. , And a back surface wall 17 located on the lower side (an example of the “float portion” in the claims) which has a hollow portion for containing gas (air, etc.) inside. ing.

  The new-type float 10 a is provided with a support 11 for supporting a solar panel 50 configured by combining the back surface wall 17 and the front surface wall 16. This is because the three sides other than the front side 24 around the support 11 are cut off, and the front side 24 is used as a hinge to form the opening 26 (surface panel 16 (solar panel 50). Can be launched on the side where The raised support portion 11 is fixed so as to maintain the raised state by compressing a part of the support portion 11 and opening a hole and screwing it. In particular, since the force applied to the support portion 11 is increased by attaching the above-described windproof net 80, such a strong fixing is necessary. Even if the side 24 which becomes the hinge breaks, the fixed shape can be maintained.

  When installing the solar panel 50, as shown in FIG. 4, the support portion 11 is raised to the surface wall 16 side so as to abut on the inner wall surface 25 of the opening 26 on the side 24 serving as the hinge. The solar panel 50 is installed so that the lower side of the front side of the solar panel 50 is supported via the fixing bracket 13 on the side 22 opposite to the side 24 on the front side.

  A receiving rib for receiving the front end 51 side of the solar panel 50 is provided on the side 22 opposite to the front side 24 which is the hinge of the support portion 11. Specifically, the receiving rib portion brings the back wall 17 close to the surface wall 16 side to provide a step structure, and the front end portion of the solar panel 50 when installing the solar panel 50 on the new float 10a. The side 51 is adapted to be received, and the front end 51 side of the solar panel 50 is prevented from being shifted forward beyond the support 11.

  When the support portion 11 is configured in this manner, the opening portion 26 is located in the vicinity of the support portion 11. However, the inner wall surface of the opening portion 26 becomes a wall surface that suppresses structural bending, Is hard to occur. In addition, because the support portion 11 is a hinge structure and is connected to the main body of the new float 10a, even if the new float 10a is bent, the support portion 11 is not easily affected, and the support portion 11 is the back surface In combination with the fact that the wall 17 and the surface wall 16 are portions that are increased in rigidity so as not to be separated too much, deformation is not caused by the influence of deflection.

  Next, the method of fixing the solar panel 50 will be described. As shown in FIGS. 2 and 3, in the solar panel 50, the front end 51 side of the solar panel 50 is fixed to the support 11 by the fixing bracket 13 on the front side. It is fixed to the new float 10a in a fixed manner.

  The front side fixing fitting 13 is an L-shaped fixing fitting including a support surface 13a and a fixing portion 13b. Specifically, the fixing portion 13b is a side opposite to the hinge, and is fixed to the surface 11a of the supporting portion 11 facing the front side of the new-type float 10a in a state where the supporting portion 11 is raised. Have. The support surface 13 a is provided to extend from the fixing portion 13 b in a direction substantially orthogonal to the fixing portion 13 b and supports the solar panel 50 with the support portion 11. And while maintaining the state which the support part 11 supported the solar panel 50, it becomes a structure fixed with a screw from the back surface side.

  In addition, although the fixing bracket 13 is screwed with respect to the support part 11 with four screws 13c, the screw hole which passes two screws 13c near the center becomes an elongated hole vertically. When the fixing bracket 13 is temporarily fixed to the supporting portion 11 by two screws 13c closer to the center, the fixing bracket 13 can be slid vertically to the supporting portion 11 May be

  In this case, in a state in which the fixing bracket 13 is temporarily fixed to the support portion 11, the fixing bracket 13 is slid downward so that there is a gap for inserting the solar panel 50 between the support surface 13a of the fixing bracket 13 and the support portion 11. After the solar panel 50 is inserted into the gap between the support surface 13a and the support portion 11, the fixing bracket 13 is slid upward to sandwich the solar panel 50 between the support surface 13a and the support portion 11 in the center Fully tighten the two screws 13c on the side. Then, after fixing the two screws 13c closer to the center and then fixing the fixing bracket 13 to the support 11 with the two outer screws 13c, the front end 51 side of the solar panel 50 (the front side) ) Is completed on the new float 10a. The same applies to the rear side fixing bracket 14.

  In particular, the fixing bracket 13 has an elongated shape as illustrated, but the length in the longitudinal direction of the fixing bracket 13 (an example of the “second direction” in the claims) is L1, and the length in the same direction in the support portion Is characterized by L1> L2. In other words, as shown in FIG. 6, the fixing bracket 13 is implemented so as to protrude the support portion 11 in a front view. It should be noted that the rear side is set to be approximately the same as the length L2, that is, the width of the fixing fitting 14 is shorter than that of the fixing fitting 13.

  The value of L1 / L2 is, for example, 1.3 to 4.0, preferably 1.4 to 3.0, and more preferably 1.5 to 2.0. Specifically, for example, L1 / L2 = 1.30, 1.35, 1.40, 1.45, 1.50, 1.60, 1.70, 1.80, 1.90, 2.00, and the like. It may be in the range between any two of the numerical values exemplified here.

  Because the new float 10a is smaller than the old float 10b used in the prior art (the manufacturing cost is reduced), the solar panel 50 can not be stably held if the fixing bracket 13 has a length matched to the support portion 11 as well. Concerns arise. Therefore, by adopting a configuration that satisfies L1> L2 as described above, it is possible to stably hold the solar panel 50 while realizing downsizing. In addition, the shape of the fixing brackets 13 and 14 can be suitably changed according to the width | variety (for example, 1500-2000 mm) of the solar panel 50. As shown in FIG. Further, the width of the fixing brackets 13 and 14 can be appropriately set in accordance with the width of the solar panel 50.

  Such a downsized new-type float 10a is characterized in that it has a substantially rectangular shape that is longer than conventional (for example, old-type float 10b). Here, assuming that the length of the long side of the new-type float 10a (here, the side extending in the front-rear direction) is L3, and the length of the short side (here, the side extending perpendicularly to the front-rear direction) is L4, L3 The value of / L4 is, for example, 1.5 to 3.0, preferably 1.6 to 2.7, and more preferably 1.7 to 2.4. Specifically, for example, L3 / L4 = 1.50, 1.55, 1.60, 1.65, 1.70, 1.80, 1.90, 2.00, 2.10, 2.20, and the like. 2.30, 2.40, 2.60, 2.80, 3.00, and may be in the range between any two of the numerical values exemplified here. In other words, it is preferable that the length L3 of the short side (or the side corresponding thereto) is shorter than that of the old type float 10b.

  Of course, the solar panel 50 used may basically be the same as that used conventionally. In particular, it is preferable that the long side of the solar panel 50 having a substantially rectangular shape and the short side of the new-type float 10a be installed substantially in parallel. Assuming that the length of the long side of the solar panel 50 is L5, the value of L3 / L5 is, for example, 0.2 to 0.7, and preferably 0.3 to 0.6. Specifically, for example, L3 / L5 = 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, and so on. It may be within the range between 0.70 and any two of the numerical values exemplified here.

  The new float 10a is not used alone, but as shown in FIG. 1, a large number of floats 10 including the new float 10a are connected by a passage joint 60 which becomes a passage when performing maintenance etc. Make up body 1

  Specifically, in the new-type float 10a, a pair of engagement protrusions 61 engaged with the passage joint 60 is formed on the front end 10f side of the float 10 on the side closer to the support portion 11. It is possible to engage by having a recess on the back side to engage with the engagement protrusion 61.

  Further, the new float 10a is a connection bolt (not shown) for connecting the passage joint 60 to the rear end 10r side of the new float 10a on the side closer to the receiving portion 12 receiving the rear end 52 side (rear side) of the solar panel 50. ) Is provided. Furthermore, when the new float 10a overlaps a part on the rear end 10r side of the new float 10a and a part on the front end 10f side, the rear end 10r is also on the front end 10f side of the new float 10a. Bolt holes 62f corresponding to the side bolt holes 62r are provided.

  Then, if the passage joint 60 is provided with bolt holes corresponding to the bolt holes 62r and the bolt holes 62f, the passage joint 60 is engaged with the engagement projection 61 with respect to one of the new floats 10a, The bolt hole 62f on the front end portion 10f side of the one new float 10a, the bolt hole 62r on the rear end portion 10r side of the other new float 10a, and the bolt hole on the passage joint 60 can be connected by a connection bolt. Further, by making the bolt holes and the like common to the old type float 10b, it is possible to realize a state in which a large number of floats 10 as well as old and new are connected via the passage joint 60. Thus, the floats 10 are connected one after another via the passage joint 60, and the float assembly 1 is configured.

3.
