[0045] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the floating structure 1 involved in the embodiment of the present application is applied to an inland floating photovoltaic system. The inland floating photovoltaic system includes a plurality of photovoltaic modules 2. The floating structure 1 includes a plurality of floating units 10. The floating units 10 include: a floating tube assembly 100 and a plurality of flexible bracket assemblies 200.

[0046] Specifically, the floating tube assembly 100 includes a plurality of first floating tubes 110 and at least one second floating tube 120, wherein the plurality of first floating tubes 110 are arranged in parallel and at intervals along a first direction, and at least one second floating tube 120 is connected to each first floating tube 110; a plurality of flexible support assemblies 200 are arranged in parallel and at intervals along a second direction to define a first avoidance space 210, and both ends of each flexible support assembly 200 are respectively connected to a first floating tube 110, and a second avoidance space 220 is provided in each flexible support assembly 200, and each second avoidance space 220 is located between any two adjacent first avoidance spaces 210, and each flexible support assembly 200 is used to support at least one photovoltaic assembly 2, and at least a portion of each photovoltaic assembly 2 is exposed to the water body through a second avoidance space 220 and two first avoidance spaces 210 adjacent to the second avoidance space 220; wherein the second direction is perpendicular to the first direction.

[0047] More specifically, in the above-mentioned embodiments, each of the first floating tube 110 and the second floating tube 120 floats on the water body.

[0048] More specifically, in the above-mentioned embodiment, the flexible support assembly 200 is disposed on a side of the photovoltaic assembly 2 close to the water body.

[0049] It should be noted that the first direction is Figure 1 The direction indicated by x, the second direction is Figure 1 The direction that y points to.

[0050] In the above-mentioned floating structure 1, since the plurality of first floating tubes 110 are arranged in parallel and at intervals along the first direction, and at least one second floating tube 120 is connected to each first floating tube 110, the at least one second floating tube 120 and the plurality of first floating tubes 110 can make the floating tube assembly 100 crisscross, so that the floating tube assembly 100 can provide buoyancy and form a relatively stable internal structure. In addition, since the plurality of flexible support assemblies 200 are arranged in parallel and at intervals along the second direction on the floating tube assembly 100, and each flexible support assembly 200 is used to support at least one photovoltaic assembly 2, the plurality of flexible support assemblies 200 can be used to support the photovoltaic assembly 2. The flexible support assembly 200 supports multiple photovoltaic components 2. In this process, since there is a first avoidance space 210 between any two flexible support assemblies 200, and a second avoidance space 220 is provided in each flexible support assembly 200, when the photovoltaic components 2 are placed on the flexible support assembly 200, at least part of each photovoltaic component 2 can be exposed to the water body through a second avoidance space 220 and two first avoidance spaces 210 adjacent to the second avoidance space 220, so as to reduce the obstruction to the side of the photovoltaic component 2 close to the water body, thereby facilitating the use of the water body to dissipate heat from the photovoltaic component 2.

[0051] Specifically, in the above embodiments, each floating tube assembly 100 has two first floating tubes 110 and one second floating tube 120 , and both ends of the second floating tube 120 are respectively connected to the middle of the two first floating tubes 110 to form an “I”-shaped floating tube assembly 100 .

[0052] Reference Figure 2 as well as Figure 3 As shown, each flexible bracket assembly 200 includes a first flexible bracket 230 and a second flexible bracket 240, the first flexible bracket 230 and the second flexible bracket 240 are arranged parallel to and spaced apart from each other along the second direction to define a second avoidance space 220, and in adjacent flexible bracket assemblies 200, a first avoidance space 210 is defined between the first flexible bracket 230 of one flexible bracket assembly 200 and the second flexible bracket 240 of another flexible bracket assembly 200;

[0053] The first flexible bracket 230 and the second flexible bracket 240 are both fixedly connected to at least one photovoltaic component 2 , and the first flexible bracket 230 and the second flexible bracket 240 are both arranged between two ends of the photovoltaic component 2 along the second direction.

[0054] It can be understood that, in the same flexible support assembly 200, since the first flexible support 230 and the second flexible support 240 are parallel and spaced apart along the second direction, a second avoidance space 220 can be defined between the first flexible support 230 and the second flexible support 240. At the same time, a first avoidance space 210 can also be defined between the first flexible support 230 and the second flexible support 240 in adjacent flexible support assemblies 200. Since the first flexible support 230 and the second flexible support 240 are both fixedly connected to at least one photovoltaic component 2, and the first flexible support 230 and the second flexible support 240 are both arranged between the two ends of the photovoltaic component 2 along the second direction, the first avoidance space 210 and the second avoidance space 220 can expose at least part of each photovoltaic component 2 to the water body, so as to reduce the obstruction to the side of the photovoltaic component 2 close to the water body, thereby facilitating the use of the water body to dissipate heat from the photovoltaic component 2.

[0055] Continue to refer to Figure 2 as well as Figure 3 As shown, each flexible support assembly 200 further includes two first support members 250, which are respectively connected to one first floating tube 110 and are both extended in the third direction in a direction away from the first floating tube 110, and one end of one of the first support members 250 away from the first floating tube 110 is connected to one end of the first flexible support 230, and the other end of the other first support member 250 away from the first floating tube 110 is connected to the other end of the first flexible support 230;

[0056] The first direction, the second direction and the third direction are perpendicular to each other.

[0057] It should be noted that the third party Figure 1 The direction indicated by z.

[0058] It can be understood that the two ends of the first flexible bracket 230 can be connected to the two first floating tubes 110 respectively through the two first support members 250. In this process, since the two first support members 250 are extended along the third direction in the direction away from the first floating tube 110, and the first flexible bracket 230 is connected to one end of the first support member 250 away from the first floating tube 110 along the third direction, when the first flexible bracket 230 is connected to the first support member 250, interference between the first flexible bracket 230 and the first floating tube 110 can be avoided, and deformation space is reserved for the first flexible bracket 230 in the third direction, so that even if the first flexible bracket 230 is deformed after supporting the photovoltaic module 2, it will still not interfere with the first floating tube 110.

[0059] Continue to refer to Figure 2 as well as Figure 3 As shown, each flexible support assembly 200 further includes two second support members 260, which are respectively connected to one first floating tube 110 and are both extended in the third direction in a direction away from the first floating tube 110, and one end of one of the second support members 260 away from the first floating tube 110 is connected to one end of the second flexible support 240, and the other end of the other second support member 260 away from the first floating tube 110 is connected to the other end of the second flexible support 240;

[0060] Among them, the first support member 250 and the second support member 260 connected to the same first floating tube 110 are spaced apart along the second direction.

[0061] It can be understood that the two ends of the second flexible bracket 240 can be connected to the two first floating tubes 110 respectively through the two second support members 260. In this process, since the two second support members 260 are extended along the third direction in the direction away from the first floating tube 110, and the second flexible bracket 240 is connected to one end of the second support member 260 away from the first floating tube 110 along the third direction, when the second flexible bracket 240 is connected to the second support member 260, interference between the second flexible bracket 240 and the first floating tube 110 can be avoided, and deformation space is reserved for the second flexible bracket 240 in the third direction, so that even if the second flexible bracket 240 is deformed after supporting the photovoltaic module 2, it will still not interfere with the first floating tube 110.

[0062] Reference Figure 4As shown, in the first support member 250 and the second support member 260 connected to the same first floating tube 110, the distance between the first support member 250 and the second support member 260 in the second direction is L1, the length of the first support member 250 in the third direction is L2, and the length of the second support member 260 in the third direction is L3, satisfying: L2>L3, and L2-L3=L1tanα;

[0063] Wherein, α is the inclination angle of the photovoltaic component 2 relative to the plane formed by the first direction and the second direction.

[0064] It should be noted that, in the above embodiment, the inclination angle α of the photovoltaic assembly 2 relative to the plane formed by the first direction and the second direction satisfies: 0≤α≤20°, and the specific value is determined according to the local latitude or the solar altitude angle at noon.

[0065] Specifically, in the above-mentioned embodiment, the plane formed by the extensions of the first direction and the second direction is parallel to the water surface of the water body.

[0066] It can be understood that since the length L2 of the first support member 250 in the third direction and the length L3 of the second support member 260 in the third direction satisfy: L2>L3, the plane formed by the extension of the first flexible bracket 230 and the second flexible bracket 240 can be set at an angle to the water surface of the water body, so that the photovoltaic component 2 placed on the first flexible bracket 230 and the second flexible bracket 240 can be set at an angle to the water surface of the water body, so that the light energy conversion efficiency of the photovoltaic component 2 can be improved. Furthermore, since L2-L3=L1tanα, the plane formed by the extension of the first flexible bracket 230 and the second flexible bracket 240 can be consistent with the inclination angle required to be set for the photovoltaic component 2, thereby improving the stability of the connection structure between the flexible bracket component 200 and the photovoltaic component 2.

[0067] Specifically, in the above-mentioned embodiment, the distance L1 between the first support member 250 and the second support member 260 in the second direction is smaller than the length of the photovoltaic component 2 in the second direction, so that the distance between the first flexible support 230 and the second flexible support 240 of the same flexible support assembly 200 will not be greater than the length of the photovoltaic component 2 in the second direction, thereby enabling the first flexible support 230 and the second flexible support 240 to provide supporting force to the photovoltaic component 2 at the same time, so as to improve the supporting effect on the photovoltaic component 2 and improve the connection stability between the flexible support assembly 200 and the photovoltaic component 2.

[0068] Reference Figure 2 as well as Figure 3As shown, the floating unit 10 further includes a pontoon assembly 300 , which is disposed between the two first floating tubes 110 , and between the water body and the photovoltaic assembly 2 , and each flexible support assembly 200 is connected to the pontoon assembly 300 .

[0069] It can be understood that when the flexible support assembly 200 supports the photovoltaic assembly 2, the photovoltaic assembly 2 will also provide pressure to the flexible support assembly 200, so that the flexible support assembly 200 has a tendency to move along the third direction toward the direction close to the water body, so that the middle part of the flexible support assembly 200 gradually sinks close to the water body. Since the pontoon assembly 300 is arranged between the water body and the photovoltaic assembly 2, each flexible support assembly 200 is connected to the pontoon assembly 300. Therefore, the pontoon assembly 300 can provide buoyancy to the flexible support assembly 200, so as to provide supporting force for the flexible support assembly 200 along the third direction toward the direction away from the water body, thereby reducing the deformation of the middle part of the flexible support assembly 200, further improving the structural stability of the flexible support assembly 200, and improving the stability of the connection relationship between the flexible support assembly 200 and the photovoltaic assembly 2.

[0070] Continue to refer to Figure 2 as well as Figure 3 As shown, the pontoon assembly 300 includes a plurality of pontoons 310 spaced apart along the second direction, and each pontoon 310 is connected to a flexible support assembly 200 at one end away from the water body along the third direction, and in each flexible support assembly 200, a first flexible support 230 is connected to one end of the pontoon 310 along the second direction, and a second flexible support 240 is connected to the other end of the pontoon 310 along the second direction.

[0071] It can be understood that, since each pontoon 310 is connected to a flexible support assembly 200, each flexible support assembly 200 can be provided with buoyancy by a pontoon 310, so as to provide the flexible support assembly 200 with a supporting force along the third direction toward the direction away from the water body, thereby reducing the deformation of the middle part of the flexible support assembly 200, further improving the structural stability of the flexible support assembly 200, and improving the stability of the connection relationship between the flexible support assembly 200 and the photovoltaic assembly 2. At the same time, in each flexible support assembly 200, since the first flexible support 230 is connected to one end of the pontoon 310 along the second direction Then, the second flexible bracket 240 is connected to the other end of the pontoon 310 along the second direction. In this way, the pontoon 310 can be connected to the first flexible bracket 230 and the second flexible bracket 240 at the same time, so that the pontoon 310 can provide buoyancy to the first flexible bracket 230 and the second flexible bracket 240 at the same time. Furthermore, since the pontoon 310 is connected to the flexible bracket assembly 200 at one end away from the water body along the third direction, in the third direction, it is possible to avoid having too many pontoon 310 structural parts between the flexible bracket assembly 200 and the photovoltaic assembly 2, so as to reduce the possibility of interference between the pontoon 310 and the photovoltaic assembly 2.

[0072] Continue to refer to Figure 2 as well as Figure 3 As shown, there are a plurality of buoyancy chamber assemblies 300 , and the plurality of buoyancy chamber assemblies 300 are disposed between two first buoyancy tubes 110 along a first direction, and each flexible support assembly 200 is connected to at least one buoyancy chamber assembly 300 .

[0073] Specifically, in the above-mentioned embodiment, each buoyancy chamber assembly 300 is connected to all the flexible support assemblies 200 .

[0074] Specifically, in the above embodiment, each floating unit 10 has three buoyancy chamber assemblies 300, which can not only provide buoyancy to the flexible support assembly 200, but also avoid the influence of too many buoyancy chamber assemblies on the heat exchange performance between the photovoltaic assembly 2 and the water body.

[0075] More specifically, in other embodiments, the number of buoyancy tank assemblies 300 of each floating unit 10 can also be four, five, six, etc., depending on the distance between the two first floating tubes 110 and the number of photovoltaic assemblies 2 supported by each flexible support assembly 200.

[0076] It can be understood that since there are multiple pontoon assemblies 300, the multiple pontoon assemblies 300 are arranged between the two first floating tubes 110 along the first direction, and each flexible support assembly 200 is connected to at least one pontoon assembly 300. Therefore, the buoyancy of each flexible support assembly 200 can be enhanced by multiple pontoon assemblies 300 to improve the supporting force of the flexible support assembly 200, further reduce the deformation of the middle part of the flexible support assembly 200, improve the structural stability of the flexible support assembly 200, and improve the stability of the connection relationship between the flexible support assembly 200 and the photovoltaic assembly 2.

[0077] Reference Figure 2 , Figure 3 as well as Figure 5 As shown, in each floating unit 10, one end of each first floating tube 110 along the second direction has a first connection portion 111, the other end of each first floating tube 110 along the second direction has a second connection portion 112, and the sides of the two first floating tubes 110 away from each other along the first direction respectively have a third connection portion 113 and a fourth connection portion 114;

[0078] Among them, multiple floating units 10 are arranged along a first direction and a second direction.
