Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic applications, and particularly to a special floating body for photovoltaic use. Background Art

[0002] In recent years, the total global photovoltaic installed capacity has been maintaining a relatively high growth trend. The photovoltaic power generation system uses the inexhaustible solar energy for power generation, without generating pollution and noise, and its advantages are beyond doubt; however, due to the small distribution density of solar radiation energy, photovoltaic power stations need to occupy a large amount of land resources. The floating photovoltaic power station can alleviate the problem of the shortage of land resources for photovoltaic power stations to a certain extent, and the sunlight reflected by the water surface can also increase the power generation of the corresponding photovoltaic modules; in addition, due to the relatively low ambient temperature, the corresponding photovoltaic modules can also maintain a better working state.

[0003] The construction of a floating photovoltaic power station necessarily involves floating bodies for supporting photovoltaic modules. Most of the floating bodies publicly available in the industry for the installation of floating photovoltaic power stations use several mutually fixed floating barrels and brackets installed on the corresponding floating barrels to realize the installation of photovoltaic modules, with complex structures, insufficient strength and stability, and inconvenient installation; moreover, the volume and buoyancy provided by such floating barrels cannot be adjusted, making it difficult to meet the actual installation requirements.

[0004] In view of this, it is necessary to provide a new special floating body for photovoltaic use. Summary of the Invention

[0010] As a further improvement of the present invention, the upper edge of the first barrel wall extends upward beyond the first support surface, and the upper edge of the second barrel wall extends upward beyond the second support surface.

[0011] As a further improvement of the present invention, the first boss further forms a third support surface extending outward from the bottom edge of the first support surface, and the second boss further forms a fourth support surface extending outward from the bottom edge of the second support surface.

[0012] As a further improvement of the present invention, the first barrel wall further forms a plurality of support ears arranged at intervals in the circumferential direction. The support ears are located below the first boss and are connected to the first boss.

[0013] As a further improvement of the present invention, the first barrel wall gradually contracts inward from top to bottom, and the first barrel body further includes a bottom wall and a connecting wall connecting the lower edge of the first barrel wall and the bottom wall. The bottom wall, the connecting wall and the first barrel wall together form an upwardly open cavity.

[0014] As a further improvement of the present invention, the first barrel body is further provided with a reinforcing rib at the bottom of the cavity. The reinforcing rib is formed on the bottom wall and the connecting wall.

[0015] As a further improvement of the present invention, at least two fixing members are formed above the cover plate.

[0016] As a further improvement of the present invention, the fixing member includes two fixing walls arranged oppositely in the horizontal direction, and the thickness of the fixing wall gradually decreases from bottom to top.

[0017] As a further improvement of the present invention, the fixing member further includes convex ribs formed on the surfaces of the two fixing walls facing away from each other.

[0018] As a further improvement of the present invention, the cross-section of the floating barrel in the horizontal direction is elliptical.

[0027] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on this embodiment is included in the protection scope of the present invention.

[0028] Refer Figure 1As shown, the photovoltaic special floating body 100 provided by the present invention includes a floating barrel and a cover plate 1 covering the floating barrel. The floating barrel includes a first barrel body 2 and a second barrel body 3 detachably installed above the first barrel body 2. In other words, the photovoltaic special floating body 100 has two different usage states. One is that the first barrel body 2 and the second barrel body 3 are assembled into one body, and then the cover plate 1 is covered above the second barrel body 3; the other is that the cover plate 1 is directly covered above the first barrel body 2. In the above two different usage states, the volume of the photovoltaic special floating body 100 itself and the bearing capacity it can provide are different, and the corresponding usage method can be selected according to the on-site installation requirements and water area conditions.

[0029] Conceivably, sealing and mounting structures that can cooperate with the cover plate 1 and the first barrel body 2 are respectively provided at the upper and lower ends of the second barrel body 3. Moreover, the height of the second barrel body 3 can also be flexibly set to better meet the different installation requirements of corresponding photovoltaic modules.

[0030] Combined Figures 2 to 6 As shown, the first barrel body 2 includes a first barrel wall 21 and a first boss 22 disposed adjacent to the upper edge of the first barrel wall 21; the second barrel body 3 includes a second barrel wall 31 and a second boss 32 disposed adjacent to the upper edge of the second barrel wall 31; the cover plate 1 includes a cover plate main body 11 and a holding wall 12 that extends downward and folds from the periphery of the cover plate main body 11 and abuts against the first boss 22 or the second boss 32. Here, the first boss 22 and the second boss 32 are respectively formed on the outer sides of the first barrel wall 21 and the second barrel wall 31, and the upper edge of the first barrel wall 21 extends upward beyond the first boss 22, and the second barrel wall 31 extends upward beyond the second boss 32. Through the above design, water leakage at the connection positions between the cover plate 1, the first barrel body 2, and the second barrel body 3 is effectively avoided, and the sealing and waterproof performance is improved.

[0031] The first boss 22 is formed with a first support surface 221 that extends outwardly and downwardly in an inclined manner, and a third support surface 222 that extends outwardly from the bottom edge of the first support surface 221; the second boss 32 is formed with a second support surface 321 that extends outwardly and downwardly in an inclined manner, and a fourth support surface 322 that extends outwardly from the bottom edge of the second support surface 321. Among them, the inclined first support surface 221 facilitates on-site operation, is conducive to the positioning and installation of the cover plate 1 and the second barrel body 3, and plays a certain guiding role; similarly, the second support surface 321 also plays a corresponding guiding role in the assembly of the cover plate 1 and the second barrel body 3, facilitating their installation. The upper edges of the first barrel wall 21 and the second barrel wall 31 extend upward beyond the first boss 22 and the second boss 32, that is to say, the first barrel wall 21 and the second barrel wall 31 respectively extend upward beyond the top edge of the first support surface 221 and the top edge of the second support surface 321. The third support surface 222 and the fourth support surface 322 are arranged to extend substantially in the horizontal direction. The abutting wall 12 is formed with a first mating surface 121 that can be adapted to the first support surface 221 or the second support surface 321; the lower edge of the second barrel wall 31 is formed with a second mating surface 311 that can be adapted to the first support surface 221. Of course, the lower edge of the abutting wall 12 is further formed with a first pressing surface 122 that presses against the third support surface 222 or the fourth support surface 322; the lower edge of the second barrel wall 31 is further formed with a second pressing surface 312 that can press against the third support surface 222.

[0032] Several first lug ears 23 protrude outwardly from the outer periphery of the first boss 22, and several second lug ears 13 corresponding to the first lug ears 23 are formed on the outer side of the abutting wall 12, and the first lug ears 23 and the second lug ears 13 are respectively provided with first mounting holes 231 and second mounting holes 131 corresponding to each other in the vertical direction. Preferably, the first lug ears 23 and the second lug ears 13 are respectively evenly distributed along the outer peripheries of the first barrel wall 21 and the abutting wall 12, and the first mounting holes 231 and the second mounting holes 131 are set as screw holes with the same specifications, and are fixedly installed by cooperating with corresponding bolts, screws, etc.

[0033] On the outer side of the second barrel wall 31, a fixing prism 33 is formed between the first lug 23 and the second lug 13 and extends in the vertical direction. Lower mounting holes corresponding to the first mounting holes 231 and upper mounting holes corresponding to the second mounting holes 131 are formed at both ends of the fixing prism 33. Wherein, the fixing prism 33 can be arranged in a penetrating manner in the vertical direction, that is, the upper mounting holes and the lower mounting holes are vertically communicated, reducing the forming and processing difficulty and facilitating the one-time assembly of the cover plate 1, the first barrel body 2 and the third barrel body 3. Preferably, the upper surface of the first lug 23 is flush with the third supporting surface 222; the lower surface of the second lug 13 is flush with the first pressing surface 122; the upper and lower ends of the fixing prism 33 are respectively flush with the fourth supporting surface 322 and the second pressing surface 312. Of course, the cross-section of the fixing prism 33 in the horizontal direction is preferably the same as the cross-sections of the first lug 23 and the second lug 13 in the horizontal direction, improving the overall aesthetics of the product and avoiding the accumulation of dirt at the corresponding installation positions.

[0034] The first barrel wall 21 further forms a plurality of support ears 24 arranged at intervals in the circumferential direction. The support ears 24 are located below the first boss 22 and are connected to the first boss 22. Through the support ears 24, the structural strength of the first boss 22 can be effectively improved, and the support ears 24 are preferably not beyond the outer edge of the first boss 22. In other embodiments of the present invention, the structural strength can also be improved by increasing the thickness of the first boss 22 in the vertical direction.

[0035] In this embodiment, the cover plate 1, the first barrel body 2 and the second barrel body 3 are all made of fiberglass material. The cross-section of the floating barrel in the horizontal direction is arranged in an ellipse, that is, the projections of the first barrel wall 21 and the second barrel wall 31 in the vertical direction on the horizontal plane are both arranged in an ellipse.

[0036] The first barrel wall 21 gradually contracts inwards from top to bottom, and the first barrel body 2 further includes a bottom wall 25 and a connecting wall connecting the lower edge of the first barrel wall 21 and the bottom wall 25. Through the above design, during transportation and handling of the first barrel body 2, they can be stacked in sequence, reducing the occupied space and being easy to fix. The first barrel wall 21, the bottom wall 25 and the connecting wall 26 together form an upwardly open cavity, and a reinforcing rib 27 is further provided at the bottom of the cavity. The reinforcing rib 27 is specifically formed on the bottom wall 25 and the connecting wall 26 so that the reinforcing rib 27 does not affect the stacking of the first barrel body 2. Here, the reinforcing rib 27 is provided with at least two and extends along the short axis direction of the elliptical floating barrel, and the reinforcing rib does not exceed the connecting wall 26 in the height direction.

[0037] An anti-slip protrusion 111 is further formed on the upper surface of the cover plate body 11, and the anti-slip protrusion 111 is preferably in the shape of a cross pattern. The cover plate 1 is further formed with at least two fixing members 14 located above the cover plate body 11 and integrally formed with the cover plate body 11, and the fixing members 14 are used for the fixed connection of the mounting bracket for the subsequent photovoltaic module. The fixing member 14 includes two fixing walls 141 oppositely arranged in the horizontal direction and a reinforcing wall 142 attached to the surface of the cover plate body 11 and connecting the lower edges of the two fixing walls 141. In other words, the thickness of the part of the cover plate body 11 between the two corresponding fixing walls 141 is larger to enhance the structural strength of the aforementioned mounting bracket mating part.

[0038] Here, the fixing member 14 is arranged in a groove shape that is open upward, and the cover plate body 11 is also arranged in an oval shape. At least two fixing members 14 extend along the short axis direction of the cover plate body 11 and are arranged at intervals along the long axis direction of the cover plate body 11. The fixing member 14 is preferably symmetrically arranged with respect to the short axis of the cover plate body 11. The thickness of the fixing wall 141 preferably gradually decreases from bottom to top, and the fixing member 14 further includes a convex rib 143 formed on the surfaces of the two fixing walls 141 facing away from each other, which is also beneficial to the structure and installation requirements of the fixing member 14. Of course, in order to realize the installation of the aforementioned mounting bracket, a corresponding fixing hole 144 is also formed on the fixing wall 141, and a fixing boss 145 with an increased thickness is formed at the position of the fixing wall 141 corresponding to the fixing hole 144. The mounting bracket can be installed at the corresponding position of the fixing member 14 through components such as angle irons and screws.

[0039] In summary, the special photovoltaic floating body 100 can adjust its own volume and buoyancy according to the actual needs of the corresponding photovoltaic module and the on-site water area conditions, change to different usage states, and ensure that the corresponding floating photovoltaic power station works more stably. And the structure is simple, the transportation and on-site handling and installation are more convenient, which is beneficial to the construction and maintenance of the floating photovoltaic power station.
