The floating bodies usually include a walkway floating body and a main floating body. The walkway floating body is used to provide a moving passage, while the main floating body is used to carry photovoltaic modules.

Specific embodiments

[0027] The core of the present utility model is to provide a walkway floating body, a floating body module and a floating photovoltaic power station, so as to reduce the comprehensive cost of the floating photovoltaic power station, and at the same time enhance the buoyancy under the photovoltaic module to improve the experience.

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the embodiments of the present utility model will be described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the utility model recorded in the claims in any way. In addition, all the contents shown in the following embodiments are not limited to what is necessary for the solution of the utility model recorded in the claims.

[0029] As Figure 1 shown, the walkway floating body provided by the embodiment of the present utility model not only needs to bear the weight of personnel, but also ensure the stable installation of the photovoltaic module 50, that is, the personnel bearing and the bearing of the photovoltaic module 50 are realized through a single floating body structure. Specifically, the walkway floating body mainly includes a main body 10 and lugs 20. Among them, the main body 10 provides the main buoyancy of the floating body. It is mostly a hollow structure and made of high-strength plastic or synthetic materials to ensure its buoyancy and durability. The shape of the main body 10 is designed as a rectangle or a square to maximize buoyancy and stability. The size of the main body 10 is adjusted according to actual needs to adapt to different photovoltaic modules 50 and installation environments. The lugs 20 are used for connection and fixation. The lugs 20 are arranged at the four corners of the main body 10, and each lug 20 includes a first connection part 210. The first connection part 210 is an annular structure, and a mounting hole 230 is formed thereon for connecting parts such as bolts to pass through. Adjacent walkway floating bodies, or other brackets on the walkway floating body and the photovoltaic module 50 can be connected through the mounting hole 230.

[0030] Based on the above structure, a partial area of the first connecting portion 210 is embedded in the main body 10 to enhance the setting stability of the first connecting portion 210. When the first connecting portion 210 provides a connection point, it can smoothly transfer the acting force to other areas on the floating body, thereby improving the connection effect. At the same time, it should be noted that the lugs 20 are arranged at the four corners of the main body 10 so that the walkway floating bodies can be butt-connected in any direction. And on the plane where the wall surface on one side of the main body 10 is located, the embedded plane size of the first connecting portion 210 occupies half of its total size. Specifically, taking a side wall of the first connecting portion 210 as an example, in the direction perpendicular to this side wall, the size of the first connecting portion 210 embedded in the side wall occupies half of the total size. When two walkway floating bodies are connected, the corresponding side walls are butted, and the two first connecting portions 210 are stacked. The part of a single first connecting portion 210 that protrudes from the side wall of the first connecting portion 210 where it is arranged will be embedded in the concave-embedded area of the first connecting portion 210 on another walkway floating body, so that the two first connecting portions 210 are stacked, and the side walls of the two walkway floating bodies where the first connecting portions 210 are arranged are kept in contact without generating gaps, improving the tight connection effect of the floating bodies and meeting the support for the human body and other components.

[0031] It should be noted that when the first connecting portion 210 is arranged at the four corners of the main body 10, it is an embedded structure in two directions, that is, on the two side walls of the main body 10. And on the plane of each side wall, the embedded size of the first connecting portion 210 occupies half of its total size in the corresponding direction, so that the walkway floating body can be connected in the length direction or the width direction through two side wall butt-joint structures. The connection method is the same as that in the above embodiment and will not be elaborated here.

[0032] The walkway floating body provided by the embodiment of the present utility model realizes support through a single floating body structure, which can improve the generalization degree compared with various forms of floating body structures. Assembly personnel do not need to distinguish the logistics first, reducing the assembly difficulty. At the same time, a single walkway floating body includes a main body 10 and lugs 20. The lugs 20 are arranged at the four corners of the main body 10, and a first connecting portion 210 partially embedded in the main body 10 is provided to smoothly transfer the acting force to other areas on the main body 10 when the first connecting portion 210 is stressed, thereby improving the connection effect. At the same time, on the plane where the wall surface on one side of the main body 10 is located, the embedded plane size of the first connecting portion 210 occupies half of its total size, so that when two walkway floating bodies are butted, the first connecting portion 210 of a single walkway floating body can just be embedded in the concave area of the first connecting portion 210 arranged on the adjacent walkway floating body, so that the two first connecting portions 210 are stacked, and the side walls of the two walkway floating bodies where the first connecting portions 210 are arranged are kept in contact without generating gaps, improving the tight connection effect of the floating bodies and meeting its support effect.

[0033] In order to further improve the connection stability of the walkway floating body, as shown in Figure 2 and Figure 3 shown, in some embodiments of the present invention, a second connecting portion 220 is further provided on a single lug 20. The second connecting portion 220 is spaced from the first connecting portion 210 to cooperate with the first connecting portion 210 to achieve stable connection. The main body 10 includes an intersecting first wall surface 110 and a second wall surface 120 in its circumferential direction. It should be noted that the circumferential direction here specifically refers to the continuously enclosed surface around the walkway floating body when it is floating on the water surface, excluding the top surface and the ground in contact with the water surface. At the same time, the area of the first wall surface 110 is larger than that of the second wall surface 120. The first connecting portion 210 is provided at the junction of the first wall surface 110 and the second wall surface 120. And in order to maintain the uniformity of the connection, the embedding dimensions of the first connecting portion 210 in the first wall surface 110 and the second wall surface 120 are equal. Since the area of the first wall surface 110 is larger, in order to ensure the connection effect when the walkway floating body is docked through the first wall surface 110, the second connecting portion 220 is embedded in the first wall surface 110, and the embedding dimension of the second connecting portion 220 in the direction perpendicular to the first wall surface 110 accounts for half of its total dimension. It is also to enable the walkway floating body to achieve a fitting effect when docked through the first wall surface 110.

[0034] On the basis of the above embodiments, adjacent walkway floating bodies can be docked and connected through two first wall surfaces 110, or can be docked and connected through two second wall surfaces 120. When two walkway floating bodies are docked and connected through two first wall surfaces 110, a wider support platform can be formed. At this time, in a single walkway floating body, the two first connecting portions 210 and the two second connecting portions 220 located on the first wall surface 110 are all docked and overlapped with the two first connecting portions 210 and the two second connecting portions 220 on another walkway floating body, and are fixedly connected into an integral structure through connectors. And when two walkway floating bodies are docked and connected through two second wall surfaces 120, a longer support platform can be formed. At this time, the two walkway floating bodies are fixedly connected into an integral structure through two stacked and docked first connecting portions 210.

[0035] Further, in order to support the photovoltaic module 50, a connection hole 240 is further provided on each lug 20 for fixing the bracket of the photovoltaic module 50. At the same time, the connection hole 240 is provided at the midpoint position of the first connecting portion 210 and the second connecting portion 220. When the connection hole 240 is used, it can transmit the acting force to the first connecting portion 210 and the second connecting portion 220, and can disperse the acting force when the first connecting portion 210 and the second connecting portion 220 are fixedly connected to other walkway floating bodies, thereby improving the connection stability at the position of the connection hole 240.

[0036] In order to maintain the conformity when the aisle floating bodies are connected, the platform where the connection holes 240 provided in the embodiments of the present utility model are arranged is recessed in the first wall surface 110. Preferably, the platform where the connection holes 240 are arranged is of a semi-circular structure. When two aisle floating bodies are butted through the first wall surface 110, the platforms where the two connection holes 240 are located are butted to form a circular structure, so that the first wall surfaces 110 of the two aisle floating bodies can be completely conformed to avoid generating gaps, and at the same time, two connection holes 240 are provided for the installation and connection of the brackets.

[0037] In addition, in order to improve the versatility of the connecting pieces on the aisle floating bodies, it is preferred that the structures of the first connecting portion 210 and the second connecting portion 220 are the same, that is, mounting holes 230 are provided on the first connecting portion 210, and connection holes 240 with the same size are also provided on the second connecting portion 220. When assembling the aisle floating bodies, only the hole positions need to be aligned and the connecting structure is required, without distinguishing the types of the connecting pieces, reducing the assembly difficulty.

[0038] Furthermore, as Figure 4 and Figure 5 shown, the embodiments of the present utility model also provide a floating body assembly, which includes a plurality of aisle floating bodies provided in the above embodiments, and several aisle floating bodies are conformed and connected through the connecting portions to form a floating body module 40, and adjacent floating body modules 40 are fixedly connected to each other through the connecting rods 30 to form an integral structure to provide sufficient area support. On this basis, in the floating body module 40, two adjacent aisle floating bodies in contact can be connected into an integral structure by means of cross connection or alignment connection. Specifically, as Figure 2 and Figure 5 shown, when the adjacent aisle floating bodies in the floating body module 40 are connected in a cross connection manner, partial areas on the first wall surfaces 110 of the two aisle floating bodies overlap, and the first connecting portion 210 of a single aisle floating body overlaps and butts with the second connecting portion 220 of the other aisle floating body. The total length of the two aisle floating bodies in the direction of the first wall surface 110 after connection is less than twice the length of the first wall surface 110. And as Figure 3 and Figure 6 shown, when the adjacent aisle floating bodies in the floating body module 40 are connected in an alignment connection manner, the two aisle floating bodies are butted by fitting their second wall surfaces 120, and the first connecting portions 210 on the two aisle floating bodies overlap and butt. At this time, the total length of the two aisle floating bodies in the direction of the first wall surface 110 after connection is equal to twice the length of the first wall surface 110.

[0039] It should be noted that the above embodiments are examples of the setting structures when the aisle floating bodies are arranged in the length direction. The two connection methods enable the floating body assembly to adjust the size in the length direction, and it can be set according to the load-bearing or length extension requirements to meet the different support requirements of the photovoltaic module 50.

[0040] Further, in some embodiments of the present utility model, both ends of the connecting rod 30 are plate-like structures extending outwards, so as to be able to overlap with the first connecting portion 210 or the second connecting portion 220. At the same time, docking holes 310 are respectively formed at both ends of the connecting rod 30, and the opening sizes of the docking holes 310 are the same as those of the mounting holes 230, so as to be able to use connecting pieces of the same size for fixed connection. And in order to meet the connection effect, preferably, two adjacent floating body components are connected into an integral structure by at least two connecting rods 30, and the two connecting rods 30 are spaced and evenly arranged to bear the same connection force. It should be noted that, as Figure 8 shown, the connecting rod 30 can be added to increase the tensile capacity of the anchoring node under relatively severe operating conditions, while in waters where a larger bearing area is required, such as Figure 7 shown, the connecting rod 30 is connected to the walkway floating body and the floating body module 40. That is, a walkway floating body is arranged between two floating body modules 40, and they are connected into a double-row structure by the connecting rods 30 on both sides of the walkway floating body, so as to extend in the width direction to provide a larger support area.

[0041] Further, as Figure 9 shown, the embodiment of the present utility model also provides a floating photovoltaic power station, which includes a photovoltaic module 50 and the floating body component provided in any one of the above. And the photovoltaic module 50 is arranged directly above the connecting rod 30 in the floating body component. On the one hand, the support structure at the bottom of the photovoltaic module 50 is reduced, so that the material usage is reduced, and the installation cost of the floating photovoltaic power station is reduced. On the other hand, the edge of the photovoltaic module 50 is directly supported by the walkway floating body, and the support effect is more stable.
