Various thermoplastic resins can be used as the molding material. For example, polyethylene and polypropylene can be preferably used. Such polyolefin resins.

如圖3和圖4所示，浮板10具備環狀浮板部F，該環狀浮板部F具有表面部11、與表面部11分離設置的背面部12、將表面部11和背面部12的外周連接的側面部13、形成於內側且從表面部11貫穿至背面部12的開口部20。應予說明，本實施方式的環狀浮板部F的整體形狀為矩形，但並不限定於矩形。另外，如圖2所示，浮板10具備支撐太陽能電池板1的一端側(圖2左側)的支撐部14。 As shown in FIGS. 3 and 4, the floating plate 10 includes an annular floating plate portion F having a surface portion 11, a back portion 12 provided separately from the surface portion 11, and a surface portion 11 and a back portion The side surface portion 13 connected to the outer periphery of the 12 is formed on the inner side and penetrates the opening portion 20 from the surface portion 11 to the back surface portion 12. In addition, the whole shape of the annular floating plate part F of this embodiment is a rectangle, but it is not limited to a rectangle. In addition, as shown in FIG. 2, the floating plate 10 includes a support portion 14 that supports one end side (left side in FIG. 2) of the solar cell panel 1.

具體而言，支撐部14由以塞住開口部20(參照圖3和4)的方式形成的部分構成，如圖3所示，以保留位於圖3右側的一端側的第1側部14a的背面部12側的第1側邊14aa的方式，將其餘側部(第2側部14b、第3側部14c和第4側部14d)的各側邊切開，能夠以第1側邊14aa為鉸鏈使以塞住開口部20的方式形成的部分於表面部11側立起。應予說明，如圖3所示，作為該鉸鏈的第1側邊14aa連接於開口部20的內壁面21的表背方向的中間部(本例中為大致中央位置)。 Specifically, the support portion 14 is composed of a portion formed to plug the opening 20 (refer to FIGS. 3 and 4), as shown in FIG. 3, so as to retain the first side portion 14a located on the one end side on the right side of FIG. The first side 14aa on the side of the back portion 12 is cut off each side of the remaining side portions (the second side portion 14b, the third side portion 14c, and the fourth side portion 14d), and the first side edge 14aa can be used as The hinge makes the part formed so as to block the opening 20 stand up on the surface part 11 side. In addition, as shown in FIG. 3, the 1st side 14aa which is this hinge is connected to the middle part of the front and back direction of the inner wall surface 21 of the opening part 20 (approximately the center position in this example).

圖6是浮板10的局部截面圖，更詳細而言，是圖3裏側第4側部14d周邊的放大圖(參照虛線區域X)，是沿圖3的X1-X1線將支撐部14從一 端側向他端側橫斷切割而成的截面立體圖。如圖6所示，在開口部20的一端側形成有承受部17，該承受部17在將支撐部14於表面部11側立起時承受支撐部14的第1側部14a。 6 is a partial cross-sectional view of the floating plate 10, in more detail, is an enlarged view of the periphery of the fourth side 14d on the back side of FIG. 3 (refer to the dashed area X), which is the support 14 from the line X1-X1 in FIG. 3 A perspective view of a cross-section cut across from one end to the other. As shown in FIG. 6, a receiving portion 17 is formed on one end side of the opening portion 20, and the receiving portion 17 receives the first side portion 14 a of the support portion 14 when the support portion 14 is raised on the surface portion 11 side.

因此，將作為鉸鏈的第1側邊14aa折彎而成為支撐部14於表面部11側立起的狀態時，成為支撐部14的第1側部14a落在形成於環狀浮板部F開口部20一端側的位置的承受部17上的狀態。換言之，環狀浮板部F的承受部17是設置太陽能電池板1時支承支撐部14的部分。 Therefore, when the first side 14aa as a hinge is bent to a state where the support portion 14 stands up on the surface portion 11 side, the first side portion 14a that becomes the support portion 14 falls on the opening formed in the ring-shaped floating plate portion F The state on the receiving portion 17 at the position on the one end side of the portion 20. In other words, the receiving portion 17 of the ring-shaped floating plate portion F is a portion that supports the supporting portion 14 when the solar cell panel 1 is installed.

另外，如圖3所示，支撐部14的第3側部14c形成為具有承受面14ca和第1受壁面14cb的大致L字形的形狀。即，從他端側(圖3左側)將支撐部14於表面部11側立起時，承受面14ca承受太陽能電池板1一端側下表面，第1受壁面14cb設置於承受面14ca的一端側，承受太陽能電池板1一端側的側壁1a(參照圖1和圖2)，由此能夠穩定地承受太陽能電池板1的一端側。 Moreover, as shown in FIG. 3, the 3rd side part 14c of the support part 14 is formed in the substantially L-shaped shape which has the receiving surface 14ca and the 1st receiving wall surface 14cb. That is, when the supporting portion 14 is raised on the surface portion 11 side from the other end side (left side in FIG. 3), the receiving surface 14ca receives the lower surface of the one end side of the solar cell panel 1, and the first receiving wall surface 14cb is provided on one end side of the receiving surface 14ca , The side wall 1a (refer to FIG. 1 and FIG. 2) on the one end side of the solar cell panel 1 can be received, so that the one end side of the solar cell panel 1 can be stably received.

應予說明，太陽能電池板1在如下狀態下，使用第1安裝配件等固定於支撐部14。即，太陽能電池板1的下表面側由支撐部14的承受面14ca承受，同時以太陽能電池板1於一端側不動的方式，太陽能電池板1的一端側的側壁1a由第1受壁面14cb承受的狀態。對此，圖1和圖2中省略了圖示。 In addition, the solar cell panel 1 is fixed to the support part 14 using a 1st attachment fitting etc. in the following state. That is, the lower surface side of the solar cell panel 1 is received by the receiving surface 14ca of the support portion 14, and at the same time, the side wall 1a on one end side of the solar cell panel 1 is received by the first receiving wall surface 14cb so that the solar cell panel 1 does not move at one end. status. In this regard, the illustration is omitted in FIGS. 1 and 2.

另一方面，如圖3所示，在環狀浮板部F的他端側設有他端側承受部11A，該他端側承受部11A形成有傾斜部11a和第2受壁面11b，該傾斜部11a的表面部11以朝向他端側靠近背面部12側的方式傾斜，該第2受壁面11b從傾斜部11a的他端側的端部11aa立起，承受太陽能電池板1的他端側的側壁1b(參照圖1和圖2)。 On the other hand, as shown in FIG. 3, the other end side receiving portion 11A is provided on the other end side of the annular floating plate portion F, and the other end side receiving portion 11A is formed with an inclined portion 11a and a second receiving wall surface 11b. The surface portion 11 of the inclined portion 11a is inclined so as to be closer to the back portion 12 side toward the other end side, and the second receiving wall surface 11b stands up from the other end portion 11aa of the inclined portion 11a, and receives the other end of the solar cell panel 1. Side wall 1b (refer to Figures 1 and 2).

設置於該環狀浮板部F他端側的傾斜部11a的結構能夠在如圖1所示傾斜配置太陽能電池板1時，使太陽能電池板1的他端側的下表面不干擾環狀浮板部F而能夠良好地配置。 The structure of the inclined portion 11a provided on the other end side of the ring-shaped floating plate portion F can prevent the lower surface of the other end side of the solar battery panel 1 from interfering with the ring-shaped floating when the solar cell panel 1 is arranged obliquely as shown in FIG. The plate part F can be arranged well.

並且，如圖1所示，太陽能電池板1以太陽能電池板1的他端側的側壁1b抵接於第2受壁面11b(參照圖3)的方式配置，使用未圖示的第2安裝配件等固定於他端側承受部11A(參照圖3)。 And, as shown in FIG. 1, the solar cell panel 1 is arranged such that the side wall 1b on the other end side of the solar cell panel 1 abuts against the second receiving wall surface 11b (refer to FIG. 3), and a second mounting accessory (not shown) is used. It is fixed to 11A of other end side receiving parts (refer FIG. 3).

應予說明，為了可根據設置太陽能電池板1的環境而將太陽能電池板1設置成適當的傾斜狀態，根據其設置環境，設計前面說明的支撐部14的高度(於表面部11側立起時的高度)。 It should be noted that in order to allow the solar cell panel 1 to be installed in an appropriate inclined state according to the environment in which the solar cell panel 1 is installed, the height of the support portion 14 described above is designed according to the installation environment (when standing on the surface portion 11 side). the height of).

另外，在圖1和圖2中，若向下側強力推壓的風等吹向太陽能電池板1，則支撐部14也被該風力向下側(圖3~圖5的背面部12側)強力推壓。 In addition, in FIGS. 1 and 2, if wind or the like strongly pushed downward is blown to the solar cell panel 1, the supporting portion 14 is also lowered by the wind (the back portion 12 side of FIGS. 3 to 5) Push hard.

這樣，將支撐部14於表面部11側立起時，承受支撐部14的第1側部 14a的承受部17(參照圖6)也被向下側(背面部12側)強力推壓，應力集中於圖3所示的虛線圓圈框A的部分(應予說明，相反側的角也相同)等，可能導致該開口部20的角部產生裂縫等，或者支承支撐部14下側的部分發生彎曲而無法充分支承支撐部14。 In this way, when the support portion 14 is raised on the surface portion 11 side, the receiving portion 17 (refer to FIG. 6) that receives the first side portion 14a of the support portion 14 is also strongly pressed downward (the back portion 12 side), and the stress Concentrating on the part of the dashed circle frame A shown in FIG. 3 (it should be noted that the corners on the opposite side are also the same), etc., may cause cracks in the corners of the opening 20, or the parts on the lower side of the support part 14 The support part 14 cannot be fully supported by bending.

另外，若產生裂縫，則可能導致水從該裂縫滲入環狀浮板部F內而浮力降低，或者無法以正確的姿態設置太陽能電池板1。應予說明，支承支撐部14下側的部分發生彎曲時，也無法以正確的姿態設置太陽能電池板1。 In addition, if cracks are generated, water may penetrate into the annular floating plate portion F from the cracks, and the buoyancy may be reduced, or the solar cell panel 1 may not be installed in a correct posture. It should be noted that even when the lower part of the support portion 14 is bent, the solar cell panel 1 cannot be installed in the correct posture.

因此，在本實施方式中，如圖3和圖4所示，在開口部20內壁面21的、比支撐部14的第1側邊14aa所連接的位置更靠近背面部12側的位置，沿開口部20的周方向設有多個凹條部22，該多個凹條部22形成在開口部20內壁面21，在表背方向上延伸，且作為加強肋發揮功能。 Therefore, in this embodiment, as shown in FIGS. 3 and 4, the inner wall surface 21 of the opening 20 is located closer to the back portion 12 than the position where the first side 14aa of the support portion 14 is connected. A plurality of concave strip portions 22 are provided in the circumferential direction of the opening portion 20. The plurality of concave strip portions 22 are formed on the inner wall surface 21 of the opening portion 20, extend in the front and back direction, and function as reinforcing ribs.

在本實施方式中，如圖3、圖4和圖6所示，為了將發揮鉸鏈作用的支撐部14的第1側邊14aa保持為直線狀，該凹條部22以凹條部22的深度從背面部12側向第1側邊14aa變淺的形式形成。 In this embodiment, as shown in FIGS. 3, 4, and 6, in order to maintain the first side 14aa of the supporting portion 14 that functions as a hinge in a straight line, the concave portion 22 has a depth equal to that of the concave portion 22. It is formed so that it may become shallow from the back part 12 side toward the 1st side 14aa.

另外，凹條部22以背面部12側的寬度最寬，從背面部12側向第1側邊14aa寬度變小的方式形成。應予說明，在本實施方式中，凹條部22為沿著截圓錐體的部分外形的形狀，但並非必要。 In addition, the grooved portion 22 is formed such that the width on the side of the back portion 12 is the widest, and the width becomes smaller from the side of the back portion 12 to the first side 14aa. In addition, in this embodiment, although the recessed line part 22 is a shape which follows the partial outer shape of a truncated cone, it is not essential.

另外，若設置這樣的凹條部22，則如上所述由於該凹條部22作為加強肋發揮功能，所以與內壁面21為平面狀的情況相比，能夠提高內壁面21的剛性。 In addition, if such a concave strip portion 22 is provided, since the concave strip portion 22 functions as a reinforcing rib as described above, the rigidity of the inner wall surface 21 can be improved compared to the case where the inner wall surface 21 is flat.

因此，即使支撐部14被向背面部12側強力推壓，也可抑制支撐部14下側(背面部12側)的內壁面21發生變形，並且由於抑制了變形，所以不會產生應力局部集中的部位，應力分散於整體，如上所述的開口部20的角產生的裂縫也可得到有效抑制。 Therefore, even if the support portion 14 is strongly pushed to the back portion 12 side, the inner wall surface 21 on the lower side of the support portion 14 (the back portion 12 side) can be suppressed from deforming, and since the deformation is suppressed, local stress concentration does not occur. The stress is dispersed throughout, and the cracks generated at the corners of the opening 20 as described above can also be effectively suppressed.

另外，在本實施方式中，如圖5所示，支撐部14具備凸條部15，該凸條部15以將支撐部14於表面部11側立起時從成為支撐部14一端側(圖5右側)的面向一端側突出的方式形成，在與第1側部14a(參照圖3和圖4)的延伸方向大致相同的方向上延伸，該凸條部15具有將支撐部14於表面部11側立起時與環狀浮板部F的表面部11面接觸的抵接面。 In addition, in this embodiment, as shown in FIG. 5, the support portion 14 is provided with a protruding stripe portion 15 that rises from the one end side of the support portion 14 when the support portion 14 is raised on the surface portion 11 side (FIG. 5) is formed so as to protrude from one end side of the surface on the right side, and extends in substantially the same direction as the extending direction of the first side portion 14a (refer to FIGS. 3 and 4). The protruding portion 15 has a support portion 14 on the surface portion. When the 11 side stands up, a contact surface that comes into surface contact with the surface portion 11 of the ring-shaped floating plate portion F.

因此，在支撐部14被向背面部12側強力推壓時，該凸條部15也可分散該推壓力，從而更進一步地將推壓力分散於整體。 Therefore, when the support portion 14 is strongly pushed to the back portion 12 side, the ridge portion 15 can also disperse the pressing force, thereby further distributing the pressing force to the whole.

此外，為提高支撐部14的剛性，支撐部14於支撐部14的寬度方向上形成有作為加強肋發揮功能且在表背方向上延伸的多個縱槽16，從而，支撐部14本身的變形也可能夠一併得到抑制。如圖6所示，通過將該縱槽16設置於與凹條部22對應的位置，推壓支撐部14時的負荷會被傳遞到提高了 剛性的凹條部22，從而能夠更進一步地抑制支撐部14下側(背面部12側)的內壁面21發生變形。 In addition, in order to improve the rigidity of the support portion 14, the support portion 14 is formed with a plurality of longitudinal grooves 16 that function as reinforcing ribs and extend in the front and back direction in the width direction of the support portion 14, thereby deforming the support portion 14 itself. It can also be suppressed together. As shown in FIG. 6, by providing the longitudinal groove 16 at a position corresponding to the grooved portion 22, the load when the support portion 14 is pressed is transmitted to the grooved portion 22 with increased rigidity, which can further suppress The inner wall surface 21 on the lower side of the support part 14 (the back part 12 side) is deformed.

以下，更具體地說明上述構成的效果。圖7是表示比較例的浮板100的圖。該浮板100中未設有凹條部22和凸條部15，除此之外具有與本實施方式的浮板10相同的形狀。另外，圖8是表示對比較例的浮板100的支撐部140和實施方式的浮板10的支撐部14施加推壓力時的負荷變化的圖。圖8中，以支撐部140和支撐部14的推壓量(壓縮位移[mm])作為橫軸，此時計量的負荷[kN]，即排斥力相當的力作為縱軸。 Hereinafter, the effect of the above-mentioned structure will be explained more specifically. Fig. 7 is a diagram showing a floating plate 100 of a comparative example. The floating plate 100 is not provided with the concave strip portion 22 and the convex strip portion 15 and has the same shape as the floating plate 10 of the present embodiment except that it is provided. In addition, FIG. 8 is a graph showing load changes when a pressing force is applied to the supporting portion 140 of the floating plate 100 of the comparative example and the supporting portion 14 of the floating plate 10 of the embodiment. In FIG. 8, the pushing amount (compression displacement [mm]) of the support portion 140 and the support portion 14 is taken as the horizontal axis, and the load [kN] measured at this time, that is, the force equivalent to the repulsive force is taken as the vertical axis.

由圖8可知，對於比較例的浮板100，從推壓量(壓縮位移[mm])剛超過7mm開始負荷[kN]呈降低的狀態，這表示支承支撐部140的部分開始彎曲。 As can be seen from FIG. 8, for the floating plate 100 of the comparative example, the load [kN] is reduced when the pressing amount (compression displacement [mm]) exceeds 7 mm, which indicates that the portion supporting the support portion 140 starts to bend.

另一方面，對於實施方式的浮板10，多少可觀察到負荷[kN]的上下浮動，所以存在發生局部彎曲的可能性，但依然可觀察到作為與排斥力相當的力的負荷[kN]的穩定上升上昇，由此可知即使在推壓量(壓縮位移[mm])達到25mm的狀態下，依然可保持充分支承支撐部14的狀態。 On the other hand, for the floating plate 10 of the embodiment, the up and down load [kN] can be observed to some extent, so there is a possibility of local bending, but the load [kN] which is a force equivalent to the repulsive force can still be observed From this, it can be seen that even in a state where the pressing amount (compression displacement [mm]) reaches 25 mm, the support 14 can still be fully supported.

應予說明，像本實施方式這樣，在將以塞住開口部20(參照圖3和圖4)的形式形成的部分立起而形成支撐部14的情況下，通過將凹條部22僅設置於開口部20的內壁面21的、以開口部20的周方向觀察時為支撐部14 的下側(即、比支撐部14更靠近背面部12側的位置)，將支撐部14向背面部12側推壓時也得到了能夠最大程度地減小變形等的結果。 It should be noted that, as in this embodiment, when a portion formed to block the opening 20 (refer to FIGS. 3 and 4) is erected to form the support portion 14, the recessed strip portion 22 is provided only The inner wall surface 21 of the opening 20 is the lower side of the support 14 (that is, the position closer to the back 12 side than the support 14) when viewed in the circumferential direction of the opening 20, and the support 14 is turned toward the back The result of being able to minimize deformation etc. was also obtained when pushing on the 12 side.

因此，優選在將以塞住開口部20(參照圖3和圖4)的形式形成的部分立起而形成支撐部14的情況下，僅在開口部20的內壁面21的、以開口部20的周方向觀察時為支撐部14下側(即、比支撐部14更靠近背面部12側的位置)設置凹條部22。 Therefore, it is preferable to stand up a part formed to block the opening 20 (refer to FIGS. 3 and 4) to form the support portion 14, and only in the inner wall surface 21 of the opening 20, the opening 20 When viewed in the circumferential direction, the recessed strip portion 22 is provided on the lower side of the support portion 14 (that is, a position closer to the back portion 12 side than the support portion 14).

另一方面，由於環狀浮板部F內封閉有氣體(例如空氣等)，所以環狀浮板部F本身會隨著氣體因晝夜溫差等的膨脹收縮而反復膨脹收縮。但與氣體膨脹時相比，收縮時環狀浮板部F的追隨性差。 On the other hand, since gas (for example, air, etc.) is enclosed in the ring-shaped floating plate portion F, the ring-shaped floating plate portion F itself repeatedly expands and contracts as the gas expands and contracts due to the temperature difference between day and night. However, the followability of the annular floating plate portion F during contraction is poor compared with that during gas expansion.

因此，長期以往環狀浮板部F可能會發生變形，若要優先抑制這樣的變形，可以在開口部20內壁面21的周方向的整個區域設置凹條部22。這種情況下，與比較例的浮板100那樣不設置凹條部22的情況相比，對推壓支撐部14的力的耐性也得了到大幅改善。 Therefore, the annular floating plate portion F may be deformed for a long period of time. To suppress such deformation preferentially, the grooved portion 22 may be provided in the entire area of the inner wall surface 21 of the opening 20 in the circumferential direction. In this case, compared with the case where the grooved portion 22 is not provided like the floating plate 100 of the comparative example, the resistance to the force pressing the support portion 14 is also greatly improved.

以上，使用實施方式說明了本發明，但本發明的技術範圍並不限定於上述實施方式的記載範圍。上述實施方式中，例示了支撐部14由以塞住開口部20(參照圖3和圖4)的方式形成的部分構成的情況，但不一定需要利用以塞住開口部20(參照圖3和圖4)的方式形成的部分來構成支撐部14。 As mentioned above, the present invention has been described using the embodiments, but the technical scope of the present invention is not limited to the description scope of the above-mentioned embodiments. In the above-mentioned embodiment, the case where the support portion 14 is constituted by a part formed to block the opening 20 (refer to FIGS. 3 and 4) is exemplified, but it does not necessarily need to be used to plug the opening 20 (refer to FIGS. 3 and 4). The part formed in the manner shown in FIG. 4) constitutes the supporting portion 14.

例如，也可以另外製作作為支撐部14的部件，將該作為支撐部14的部件安裝於環狀浮板部F，也可以在比環狀浮板部F的開口部20更靠近一端側的位置一體形成作為支撐部14的結構。 For example, it is also possible to separately fabricate a member as the support portion 14 and attach the member as the support portion 14 to the ring-shaped floating plate portion F, or at a position closer to one end side than the opening 20 of the ring-shaped floating plate portion F. The structure is integrally formed as the support part 14.

但是，向本實施方式這樣利用以塞住開口部20(參照圖3和圖4)的方式形成的部分來形成支撐部14，有材料利用效率高等很多優點，因此支撐部14優選利用以塞住開口部20(參照圖3和圖4)的形式形成的部分來構成。 However, in this embodiment, the support portion 14 is formed by using a portion formed to block the opening 20 (refer to FIGS. 3 and 4). This has many advantages such as high material utilization efficiency. Therefore, the support portion 14 is preferably used to plug the opening 20 (see FIGS. 3 and 4). The opening 20 (refer to FIGS. 3 and 4) is formed in the form of a part.

應予說明，在支撐部14不使用以塞住開口部20(參照圖3和圖4)的形式形成的部分的情況下，也優選設置開口部20。這是因為通過這樣設置開口部20，能夠減少環狀浮板部F記憶體在的氣體(例如空氣等)的量，相應地，能夠減小氣體因晝夜溫差等產生的膨脹收縮力。 It should be noted that in the case where the supporting portion 14 does not use a portion formed to block the opening 20 (refer to FIGS. 3 and 4 ), it is also preferable to provide the opening 20. This is because by providing the opening portion 20 in this way, the amount of gas (for example, air, etc.) present in the memory of the ring-shaped floating plate portion F can be reduced, and accordingly, the expansion and contraction force of the gas due to the temperature difference between day and night can be reduced.

但是，環狀浮板部F記憶體在的氣體會產生使浮板10漂浮於水面的浮力，所以通過設置開口部20而減少的氣體量，自然需要控制在考慮太陽能電池板1的重量而得到能夠在水面漂浮的浮力的程度。 However, the gas in the memory of the ring-shaped floating plate portion F will generate buoyancy for the floating plate 10 to float on the water surface, so the amount of gas reduced by providing the opening portion 20 naturally needs to be controlled in consideration of the weight of the solar panel 1 The degree of buoyancy that can float on the water.

另外，本實施方式的浮板10如上所述可適宜通過吹塑成型來製作，但也可以採用吹塑成型以外的製造方法來製造。 In addition, the floating plate 10 of the present embodiment can be suitably manufactured by blow molding as described above, but it may be manufactured by a manufacturing method other than blow molding.

由此，本領域技術人員根據申請專利範圍的記載應當理解，本發明的 浮板10並不限定於上述具體實施方式，可以加以各種變更或改進，這種變更或改進後的發明也包括在本發明的技術範圍之內。 Therefore, those skilled in the art should understand from the description of the scope of patent application that the floating plate 10 of the present invention is not limited to the above-mentioned specific embodiments, and various changes or improvements can be made, and the invention after such changes or improvements is also included in the present invention.
