Description
Technical Field
The application relates to the technical field of clean energy, in particular to a bracket applied to a floating type photovoltaic array floating body on water.
Background
Solar energy is a clean energy source. The direct conversion of solar energy into electrical energy by means of photovoltaic power stations is an efficient way of utilizing solar energy. Photovoltaic power plants are currently mainly built on the ground, for example by using idle land. However, because of the small intensity of the distribution of the irradiation energy, which is greatly affected by the meteorological conditions, the land-based photovoltaic power plant generally needs to occupy a large area. In economically developed areas, land resources are valuable, and construction of photovoltaic power stations is greatly limited. Waterborne photovoltaic refers to the construction of photovoltaic power stations using the surface of the water that is left idle. The water photovoltaic power station has the advantages of not occupying land resources, reducing water evaporation, avoiding algae growth and the like, and has wide development prospect.
One embodiment of a photovoltaic power plant on water is to use a floating photovoltaic array. The floating bodies of the existing floating type photovoltaic array all adopt integrated floating bodies with fixed angles. Because different regions have different sun irradiation angles, the floating body with a fixed angle is difficult to adapt to a plurality of regions, and therefore, the cost is easily increased due to multiple mold opening. And because the floating body must be installed according to a specific direction, the difficulty of installation is increased, and the construction efficiency is reduced. In order to improve the construction efficiency, sometimes, a pre-installation method is necessary. However, this method requires a large-sized construction machine, and requires a construction site.

Fig. 2A-2G are schematic diagrams of a primary floating body according to one embodiment of the application. Fig. 2A and 2B are front and rear perspective views of the main floating body, and fig. 2C and 2D are top and front views of the main floating body, showing the overall shape of the main floating body. Fig. 2E is a cross-sectional view of the main floating body, illustrating the internal structure of the main floating body. And fig. 2F and 2G are partial enlarged views of the support and the pull tab of the main floating body, respectively, showing the specific structure of both.
As shown, the main float 200 includes a main body 201. On the upper surface of the body 201 is substantially planar, comprising one or more abutments 202. One or more groups of pull lugs 203 are also arranged on the main body 201, and each group of pull lugs comprises more than 2 pull lugs.
According to one example of the application, the upper surface of the body 201 is generally rectangular. 4 supports are respectively arranged at 4 corners of the main floating body. The support is used for being connected with the bracket so as to support the solar panel fixed with the bracket. And 4 groups of pull lugs are respectively arranged on two side surfaces of the main floating body connected with the transverse floating body, and each group is 2. Each group of pull lugs is used for being connected with one transverse floating body. Specifically, each set of tabs includes a first tab 204 disposed at the corner of the main body and extending outwardly from the main body and a second tab 205 disposed on the side of the main body, the second tab 205 being adjacent to the first tab 204 but spaced from the first tab 204.
According to one embodiment of the application, the main floating body is not slightly concave on the two sides connected with the transverse floating body, so that the strength of the main body is improved. Further, according to an embodiment of the present application, a plurality of grooves 206 are provided on both sides of the main floating body connected to the lateral floating body, respectively, and the second pull tab 205 of each set of pull tabs is received in the groove 206. Further, according to one embodiment of the application, a support 202 is provided on the upper surface 201 of the main floating body between the first pull tab 204 and the second pull tab 205 of each set of pull tabs. The design of the interval between the support and the pull lug is also beneficial to improving the strength of the main body, in particular the action of lateral external force.
The strength of the main floating body and the firm connection of the main floating body and the transverse floating body have a significant influence on the stability of the photovoltaic array. The main floating body of the application is improved in material and structure so as to improve the strength of the main floating body and the firmness of connection with the transverse floating body.
According to one example of the application, the main floating body is made of high-density polyethylene material, and has high strength, good toughness and durability. According to an example of the application, the main floating body and the transverse floating body are connected by adopting at least double pull lugs, so that the firmness of connection is greatly increased. In extreme conditions, even if one tab breaks, the other tab is sufficient to firmly connect the main and lateral floats. Moreover, the design enables the interval between maintenance to be longer, and reduces the overall maintenance cost. According to an embodiment of the application, the recess in the side of the main floating body can accommodate not only the second pull tab of the main floating body but also a third pull tab situated at the corner of a set of pull tabs of similar arrangement of the transverse floating body. Similarly, the first pull tab on the corner of the main float may also be received in a recess similarly provided in the transverse float to receive the fourth pull tab. Therefore, the main floating body and the transverse floating body are connected through at least two pull lugs, and an embedded structure can be formed between the main floating body and the transverse floating body, so that the connection strength between the main floating body and the transverse floating body is further improved. Meanwhile, the design of the grooves on the side face of the main floating body is beneficial to improving the strength of the main floating body.
Further, as shown in the figure, mesh concave lines with different patterns are respectively arranged on the upper surface and the lower surface of the main floating body. The net concave line can increase the capability of the main floating body to resist external force and increase the strength of the main floating body. The patterns on the upper surface and the lower surface are different, so that the directions of the main floating body resisting the external force are different, and the strength of the main floating body is improved. According to one embodiment of the application, the upper surface is provided with net-shaped concave lines 207 having 42 degrees and 132 degrees perpendicular to each other. The lower surface is provided with 0 and 90 degree mutually perpendicular reticular concave lines 208.
Further, according to one embodiment of the application, an opening 209 is provided through the main float. The openings are also present to increase the strength of the main floating body. According to one embodiment of the application, the opening is in the form of a bar, the long side of which is perpendicular to the direction of the transverse floating body. Due to the fixing effect of the transverse floating body, the longitudinal stress is not easy to damage. The directional arrangement of such openings increases the resistance of the main floating body to transverse stresses, making the main floating body stronger.
Further, referring to fig. 2E, the main floating body is hollow (the hatched portion in the figure indicates a hollow cross section). The hollow floating body can reduce material consumption and increase the buoyancy of the main floating body. At the same time, hollow structures also have certain benefits in terms of resistance to stress and deformation.
Further, referring to fig. 2F, a support 203 is provided on the main floating body, and the support is generally bar-shaped and includes a trapezoidal platform 210 and a "T" shaped rib 211 (the shape of the cross section is shown in fig. 2E) extending from the trapezoidal platform. Two grooves are formed between the top lateral extensions 212 of the "T" shaped ribs and the trapezoidal shaped platform 210 for mating with the mounting of the bracket.
Further, referring to fig. 2G, the pull tab 201 is integrally formed with the main float and extends naturally outward from the main float. The tab includes a through hole 214 to allow a screw 213 to pass therethrough. Radial and annular reinforcing ribs 215 are provided on the tab in order to increase the strength of the tab.
Fig. 3A-3F are schematic views of a lateral floating body according to one embodiment of the present application. Fig. 3A and 3B are front and rear perspective views of the lateral floating body, fig. 3C is a top view of the lateral floating body, and fig. 3D is a front view of the lateral floating body, showing the overall shape of the lateral floating body. And fig. 3E is a sectional view of the lateral floating body, showing the internal structure of the lateral floating body. And fig. 3F is a partial enlarged view of the tab, showing its specific structure.
The lateral float comprises a body 310. The upper surface of the transverse floating body is approximately strip-shaped. The upper surface of the transverse floating body is basically flat and comprises at least one group of pull lugs, and each group of pull lugs comprises at least two pull lugs. According to an example of the present application, as shown in the drawing, 4 sets of pull lugs, 2 each, are provided on both sides of the lateral floating body 300 connected to the main floating body. Each set of lugs comprises a third lug 301 arranged at a corner of the transverse floating body and extending outwards and a fourth lug 302 arranged on a side of the transverse floating body, the fourth lug 302 being adjacent to the third lug 301 and spaced apart from the third lug 301 at the corner. Further, according to an embodiment of the present application, a plurality of grooves 303 are provided on both sides of the main floating body connected to the lateral floating body, respectively, and the fourth tab 302 of each set of tabs is received in the groove 303.
The strength of the lateral floats and the strong connection between the lateral floats and the main floats have a significant impact on the stability of the photovoltaic array. The transverse floating body of the application is improved in material and structure to improve the strength and the firmness of connection.
According to one example of the application, the transverse floating body is made of high-density polyethylene material, and has high strength, good toughness and durability. According to an example of the application, the connection mode of at least two pull lugs is adopted between the transverse floating body and the main floating body, so that the firmness of connection is greatly increased. In extreme conditions, even if one tab breaks, the other tab is sufficient to firmly connect the main and lateral floats. Moreover, the design enables the interval between maintenance to be longer, and reduces the overall maintenance cost. According to an embodiment of the application, the recess in the side of the transverse floating body can accommodate, in addition to the fourth pull tab of the transverse floating body, also the first pull tab situated at the corner of a set of pull tabs of a similar arrangement of the main floating body. Similarly, the third tab at the corner of the transverse floating body may also be received in a similarly disposed recess in the main floating body that receives the second tab. Therefore, the main floating body and the transverse floating body are connected through at least two pull lugs, and an embedded structure can be formed between the main floating body and the transverse floating body, so that the connection strength between the main floating body and the transverse floating body is further improved. Meanwhile, the design of the grooves on the side surfaces of the transverse floating bodies is beneficial to improving the strength of the main floating bodies.
Further, as shown in the figure, mesh concave lines with different patterns are respectively arranged on the upper surface and the lower surface of the transverse floating body. The netlike concave lines can increase the capability of the transverse floating body to resist external force and increase the strength of the transverse floating body. The upper and lower surface patterns are different so that the direction of the external force resisted by the transverse floating body is also all different. According to one embodiment of the application, the upper surface is provided with net-shaped concave lines 304 at 45 and 135 degrees perpendicular to each other. The lower surface is provided with 0 and 90 degree mutually perpendicular net-shaped concave lines 305.
Further, referring to fig. 3D and 3E, the lower surface of the lateral float is provided with a non-penetrating opening 306 (the hatched portion in the figure shows a hollow cross section). The openings are also present in order to increase the strength of the transverse floating body. According to one example of the application, the opening is bar-shaped and stepped in the direction of the transverse floating body, gradually shrinking from the lower surface to the upper surface. In order to increase the strength, the lower part of the upper surface is provided with reinforcing ribs.
The strip-shaped opening at the lower part of the transverse floating body can reduce material consumption and increase buoyancy of the transverse floating body. At the same time, the strip-shaped opening structure has a certain benefit for resisting stress.
Further, referring to fig. 3F, the pull tab is integrally formed with the lateral float and extends naturally outward from the lateral float. The pull lugs are provided with through holes for allowing the screws to pass through. In order to increase the strength of the pull lugs, radial and annular reinforcing ribs are arranged on the pull lugs.
Fig. 4A-4E are schematic views of a longitudinal floating body according to one embodiment of the application. Fig. 4A and 4B are front and rear perspective views of the longitudinal floating body, fig. 4C is a top view of the longitudinal floating body, and fig. 4D is a front view of the longitudinal floating body, showing the overall shape of the longitudinal floating body. And fig. 4E is a sectional view of the longitudinal floating body, showing the internal structure of the longitudinal floating body.
The longitudinal float includes a body 410. The upper surface of the longitudinal floating body is approximately strip-shaped and comprises one or more groups of pull lugs, and each group of pull lugs comprises at least 2 pull lugs. As shown, the longitudinal floating body 400 is provided with 2 sets of pull lugs on both sides to which the transverse floating bodies are connected, 2 sets each (4 sets of pull lugs may be included if 4 transverse floating bodies are connected). Each set of lugs comprises a fifth lug 401 arranged on one corner of the longitudinal floating body and extending outwards, and a sixth lug 402 arranged on the side surface of the longitudinal floating body, wherein the sixth lug 402 is spaced from the fifth lug 401 on the corner close to the fifth lug 401. Each group of pull lugs of the longitudinal floating body is used for being connected with one transverse floating body. Further, according to an embodiment of the present application, a plurality of grooves 403 are provided on the sides of the longitudinal floating body connected to the transverse floating body, respectively, and the sixth tab 402 of each set of tabs is received in the groove 403.
The longitudinal floating body of the application is improved in material and structure to improve the strength and the firmness of connection. According to one example of the application, the longitudinal floating body is made of high-density polyethylene material, and has high strength, good toughness and durability. According to an example of the application, the connection mode of at least two pull lugs is adopted between the longitudinal floating body and the transverse floating body, so that the firmness of connection is greatly increased. In extreme conditions, even if one tab breaks, the other tab is sufficient to firmly connect the main and lateral floats. Moreover, the design enables the interval between maintenance to be longer, and reduces the overall maintenance cost. According to an embodiment of the application, the recess in the side of the longitudinal floating body can accommodate not only the sixth lug of the longitudinal floating body but also a third lug situated at the corner of a set of lugs of a similar arrangement of the transverse floating body. Similarly, the third tab at the corner of the transverse floating body may also be received in a similarly disposed recess in the longitudinal floating body that receives the sixth tab. Therefore, the longitudinal floating body and the transverse floating body are connected through at least two pull lugs, and an embedded structure can be formed between the longitudinal floating body and the transverse floating body, so that the connection strength between the longitudinal floating body and the transverse floating body is further improved. Meanwhile, the design of the grooves on the side surfaces of the longitudinal floating bodies is beneficial to improving the strength of the main floating bodies.
Further, as shown in the figure, mesh concave lines with different patterns are respectively arranged on the upper surface and the lower surface of the longitudinal floating body. The net concave line can increase the capability of the longitudinal floating body to resist external force and increase the strength of the longitudinal floating body. The patterns of the upper surface and the lower surface are different, so that the directions of the external force resistance of the longitudinal floating bodies are also different. According to one embodiment of the application, the upper surface is provided with net-shaped concave lines 404 at 45 and 135 degrees perpendicular to each other. The lower surface is provided with 0 and 90 degree mutually perpendicular net-shaped concave lines 405.
Further, referring to fig. 4D and 4E, the lower surface of the longitudinal floating body is provided with a non-penetrating opening 406 (the hatched portion in the figure shows a hollow cross section). The openings are also present in order to increase the strength of the longitudinal floating body. According to one example of the application, the opening is strip-shaped in the direction of the longitudinal float and is stepped, tapering from the lower surface to the upper surface. In order to increase the strength, the lower part of the upper surface is provided with reinforcing ribs.
The strip-shaped opening at the lower part of the longitudinal floating body can reduce material consumption and increase buoyancy of the longitudinal floating body. At the same time, the strip-shaped opening structure has a certain benefit for resisting stress.
Fig. 5A-5E are schematic diagrams of an interlateral floating body according to one embodiment of the present application. Fig. 5A and 5B are front and rear perspective views of the inter-lateral floating body, fig. 5C is a top view of the inter-lateral floating body, and fig. 5D is a front view of the inter-lateral floating body, showing the overall shape of the inter-lateral floating body. And fig. 5E is a sectional view of the inter-lateral floating body, showing an internal structure of the inter-lateral floating body.
The interlateral float includes a body 510. The interlateral floating body 500 is generally square and includes a plurality of tabs 501-504 disposed at corners and extending naturally outward. According to one embodiment of the application, the pull lugs are arranged on the sides of the intertransverse floating body. According to one example of the application, the 4 lugs of the intertransverse floating body are connected to both the main floating body and the transverse floating body. Or 2 pull lugs of the transverse floating body are simultaneously connected to the main floating body and the transverse floating body; the other 2 pull lugs are connected to the transverse floating body. According to one embodiment of the application, the transverse floating body is made of high-density polyethylene material, and has high strength, good toughness and durability and long service life. Furthermore, the inter-transverse floating body adopts various improvements in structure so as to improve the strength and the connection firmness of the inter-transverse floating body. For example, a double-pull lug connection mode is adopted between the transverse floating body and other floating bodies, so that the connection firmness is greatly increased. In extreme conditions, even if one pull tab breaks, the other pull tab is sufficient to firmly connect the intertransverse floating body to the other floating body, thereby enabling timely maintenance. The design of the grooves in the side surfaces of the transverse floating bodies is also beneficial to improving the strength of the transverse floating bodies.
Further, as shown in the figure, mesh concave lines with different patterns are respectively arranged on the upper surface and the lower surface of the transverse floating body. The netlike concave lines can increase the capability of the inter-transverse floating body to resist external force and increase the strength of the inter-transverse floating body. The patterns of the upper surface and the lower surface are different, so that the directions of the external force resistance of the transverse floating bodies are all different. According to one example of the present application, the upper surface is provided with net-shaped concave lines 505 of 45 degrees and 135 degrees perpendicular to each other.

Fig. 9A-9C are schematic diagrams of a mounting bracket according to one embodiment of the application. Fig. 9A shows a schematic cross-sectional view of a solar panel mounted to a main floating body by brackets. As previously indicated, the main float supports the other solar panels by means of two sets of short and long supports. Fig. 9B shows the mounting structure of the short bracket; fig. 9C shows the mounting structure of the long bracket. Fig. 10 is an exploded view of a simplified version of a mounting bracket according to another embodiment of the present application. Fig. 11A-11F are schematic diagrams of a stent structure according to an embodiment of the present application.
According to one embodiment of the present application, as shown in fig. 9A, the tilting of the solar panel 903 by a tilt angle is achieved by providing support for the solar panel 903 by long brackets 901 and short brackets 902. One end of the long and short brackets 901 and 902 is mounted to the supports 9051 and 9052 of the main floating body 904, thereby achieving connection with the main floating body 904. The other ends of the long and short brackets are mounted on the metal frame of the solar panel 903, thereby realizing the connection with the solar panel 903. The heights of the long and short brackets 901 and 902 may be processed according to actual needs, and the main floating body 903 itself is flat. Therefore, the photovoltaic array can realize different angles so as to be suitable for different regions. Moreover, the bracket can be an aluminum alloy member, so that the cost is low; the main floating body and other floating bodies can be standardized components for mass production, so that the cost is reduced. On the other hand, the standardization of the main floating body also ensures that the angle of the main floating body is not required to be considered during installation, thereby facilitating the installation.
As shown in fig. 9B and 11A, the long bracket 901 includes a bracket main body 9011 and a connector 9012. Both may be formed of parallel sheet metal material, including parallel webs at regular intervals between the sheet metal. In particular, the connecting piece 9012 comprises an upper portion 9013 and a lower portion 9014, and the lower portion 9014 is folded inwards, forming two bottom edges 9015 which can extend inwards on the trapezoidal platform of the main floating body support 9051. The lower portion 9014 of the connector 9012 is shaped to mate with the T-shaped ridge of the support 9051 of the main float, and the two bottom edges 9015 are adapted to be inserted into the channel between the horizontal extension of the T-shaped ridge of the support 9051 of the main float and the trapezoidal platform in a close mating relationship to effect the mounting therebetween. The bracket body 9011 includes an upper portion 9016, a middle portion 9017, and a lower portion 9018. The lower portion 9018 is folded outwardly forming two bottom edges 9019 extending outwardly on the trapezoidal platform of the main float support 9051. The lower portion 9018 of the bracket body 9011 is cooperatively shaped with the connector 9012 so that installation therebetween can be achieved. The upper portion 9016 of the bracket body 9011 includes a bracket plate 90161 extending outwardly therefrom at an angle and bent at a distal end to form a hem. The retainer plate 90161 cooperates with the bead 90162 to compress a portion of the solar panel frame therebetween and secure the solar panel to the long support by way of a through latch.
As shown in fig. 9C, the short stent 902 is similar in structure to the long stent 901, including a stent body 9021 and a connector 9022. The short stent connector 9022 is similar to the long stent connector 9012, but is shorter in height and will not be described again. The short stent body 9021 comprises an upper portion 9023 and a lower portion 9024, but there is no intermediate portion; and, the upper portion 9023 is at an angle to the lower portion 9024. The lower portion 9024 is shaped to mate with the attachment piece 9022 and is bent outwardly to form two bottom edges extending outwardly on the trapezoidal platform of the main float support 9052. For added strength, the lower portion 9024 and the connector 9022 may be fixed in shape by a through latch 9025. The upper portion 9023 of the short shelf includes a pallet 9026 extending therefrom and bent inwardly at the edges. The bending platen 9027, which mates with the short shelf, includes a first portion 90271 that mates with the pallet 9026 and bends outward at the edge; the bending platen 9027 includes a second portion 90272 which mates with one side of the upper portion 9023 of the short shelf and is bent inward at the edge. The first portion 90271 of the bent press plate 9027 and the support plate 9026 can press a portion of the frame of the solar panel therebetween, and the first portion 90272 of the bent press plate 9027 and the upper portion 9023 of the short bracket can be fixed by a through latch, thereby also pressing the frame of the solar panel.
According to one embodiment of the application, the lower part of the long or short bracket body may be arranged to extend both inwardly and to cooperate with the T-shaped ribs on the main float support and to extend outwardly to form a support structure, whereby the connection pieces are omitted, so that the combination of the bracket body and the main float support is tighter.
The outward bending portion of the bracket can be omitted under the condition of the allowed strength, so that the design of the bracket is simpler and lower in cost. According to an embodiment of the present application, referring to fig. 10 and fig. 11C, 11D, 11E and 11F, other portions of the present embodiment are the same as the previous embodiment except for the partial structure of the long and short brackets. The master float 1001 is provided with 4 abutments 1002-1005. Two sets of 4 brackets 1006-1009, each of length, may be mounted on 4 brackets 1002-1005 on the master float 1001 to support the panel 1010. The bent press plates 1010-1014 cooperate with the brackets 1006-1009 to secure the frame 1020 of the panel 1010 to the brackets 1006-1009, thereby achieving the securement of the panel 1010.
Referring to fig. 11C-11F, the long stand 1101 includes an upper portion 1103, a transition portion 1104, a middle portion 1105, and a lower portion 1106. Short leg 1102 includes an upper portion 1107 and a lower portion 1108. The bending press plates 1111 and 1112 are respectively matched with the long and short brackets 1101 and 1102 to fix the battery plate.
The short leg 1102 of this embodiment is very similar to the short leg 902 of the previous embodiment, but the lower portion 1108 is modified to bend inwardly whereby the lower portion 1108 directly mates with the T-shaped ridge of the main float support to effect installation between the leg and the main float, thereby omitting the connector. Similarly, the lower portion 1106 of the long bracket 1101 is also modified to bend inwardly to mate directly with the T-shaped rib of the main float support, omitting the connector.
Another variation of this embodiment is that a transition 1104 is added to the long support 1101. The existence of the transition part can not only increase the strength of the long bracket 1101, so that the transition is more gentle, but also has stronger external force resistance, and can also support the fixing mode of the bending pressing plate, thereby being more beneficial to the implementation of installation.
According to one embodiment of the application, the photovoltaic array is anchored by a rope to make the floating photovoltaic array more stable. If the rope is fixed to a single floating body, damage to the floating body is easily caused. For the floating body provided by the application, the rope is skillfully connected to a plurality of floating bodies through the combination between the main floating body and the transverse floating body, so that the damage to the floating bodies is avoided, and no change is required to be made to the floating bodies.
Fig. 12 is a schematic view of an anchoring structure of a photovoltaic array according to one embodiment of the present application. Fig. 13 is a schematic view of a pull member mated with a floating body in accordance with one embodiment of the present application. Fig. 14 is a schematic view of a pull and float installation according to one embodiment of the present application.
As shown in fig. 12-14, in the space enclosed by the main floats and the transverse floats, either inter-transverse floats can be added or a pull member connected with the rope can be fixed, so that the rope is connected with a plurality of floats.
As shown, the pull 1201 includes four outwardly extending arms, each of which includes an edge through hole 1202-1205 at its distal end. The other ends of the arms are connected to each other to form the center of the pull 1201. In the center of the pull 1201 there is a central through hole 1206 for connection to the tether by a tether securing pin, while each of the edge through holes 1202-1205 is connected to the pull lugs of both the main float and the lateral float. Thus, the pull 1201 forms a stable structure with its surrounding main and lateral floats 1210, 1220, 1230, 1240. The tension of the rope is thus dispersed, protecting the float.
As shown in fig. 14, the anchor structure 1400 includes pull members 1401-1404 mounted in a photovoltaic array. The pull-out element is preferably mounted in the region enclosed by the main and transverse floats. Pull members 1401-1404 are connected to posts 1409 and 1410 by cords 1405-1408. As shown, the rope may be secured to the column by a hoop. Only the main and lateral floats around the pulls 1403 and 1404 are shown in fig. 14, the main and lateral floats around the other pulls and in the photovoltaic module. Preferably, a plurality of pulls are included in the photovoltaic array, and each post is also connected to the plurality of pulls. Thus, for a photovoltaic array on water, the ropes anchoring it are dispersed, while the ropes are also dispersed, connected to the floating body, whereby an overall stable structure can be formed. This is very advantageous for improving the resistance of the photovoltaic array on water against environmental influences such as weather changes; moreover, the person skilled in the art should notice that no change is made to the main floating body or the transverse floating body, the anchoring conditions of rope dispersion and floating body dispersion are naturally met, and meanwhile, the difficulty is reduced for construction, so that the waterborne photovoltaic array formed by the floating bodies can meet the construction environment for constructing the waterborne photovoltaic power station, and quick installation and construction are realized.
The above embodiments are provided for illustrating the present application and not for limiting the present application, and various changes and modifications may be made by one skilled in the relevant art without departing from the scope of the present application, therefore, all equivalent technical solutions shall fall within the scope of the present disclosure.
