A third shaft sleeve 123 is arranged between the two ends, the first rotating shaft 121 extends into the first shaft sleeve 111 and is rotatably connected to the first shaft sleeve 111, and the second rotating shaft 122 extends into the second shaft sleeve 141 and is rotatably connected to the second shaft sleeve 141; a third rotating shaft 131 is arranged at one end of the second support member 13, the third rotating shaft 131 extends into the third shaft sleeve 123 and is rotatably connected to the third shaft sleeve 123, and the other end of the second support member 12 abuts against one side of any one of the limiting protrusions 113 close to the first shaft sleeve 111.

[0048] Specifically, Figure 1 A schematic diagram of the structure of the bracket 1 in an embodiment of the present application is shown. The fixing device includes the bracket 1, and the bracket 1 includes a bottom plate 11, a first support member 12, a second support member 13 and a crimping member 14. Figure 2 A schematic diagram of the structure of the base plate 11 in an embodiment of the present application is shown, wherein a first sleeve 111 and at least two limiting protrusions 113 are provided on the upper surface of the base plate 11, the limiting protrusions 113 are distributed in parallel, and the limiting protrusions 113 are strip-shaped, and the first sleeve 111 and the limiting protrusions 113 are integrally formed with the base plate 11. Figure 3 A schematic diagram of the structure of the crimping piece 14 in the embodiment of the present application is shown. The crimping piece 14 is located at the top of the device, and a second sleeve 141 is provided at the bottom. The second sleeve 141 and the crimping piece 14 are integrally formed. The crimping piece 14 is used to fix and crimp the photovoltaic component 2. Figure 4The schematic diagram of the structure of the first support member 12 in the embodiment of the present application is shown, the lower end of the first support member 12 is fixedly connected with a first rotating shaft 121, the upper end of the first support member 12 is fixedly connected with a second rotating shaft 122, the first rotating shaft 121 extends into the first sleeve 111 and is rotatably connected to the first sleeve 111, the second rotating shaft 122 extends into the second sleeve 141 and is rotatably connected to the second sleeve 141, and a third sleeve 123 is provided in the middle of the first support member 12. The first rotating shaft 121, the second rotating shaft 122, and the third sleeve 123 are integrally formed with the first support member 12. Figure 5 The schematic diagram of the structure of the second support member 13 in the embodiment of the present application is shown. A third rotating shaft 131 is arranged at the upper end of the second support member 13. The third rotating shaft 131 extends into the third sleeve 123 and is rotatably connected to the third sleeve 123. The lower end of the second support member 13 abuts against the side of the limiting protrusion 113 close to the first sleeve 111. That is, a rotating connection structure is formed between the first support member 12 and the bottom plate 11, the second support member 13 and the crimping member 14. The number of limiting protrusions 113 is two, three or more. The more the number is, the more adjustable gears the bracket 1 has. Specifically, as Figure 6 As shown, when the first support member 12 and the second support member 13 are adjusted to reduce the angle between the two and the horizontal line, the larger the distance between the limiting protrusion 113 abutted by the lower end of the second support member 13 and the first sleeve 111, the smaller the plumb height of the bracket 1, and the height of the photovoltaic module 2 fixed to the side of the bracket 1 is reduced. If the height of the other opposite side of the photovoltaic module 2 is less than the height of the side fixed to the bracket 1, the inclination angle of the photovoltaic module 2 increases; if the height of the other opposite side of the photovoltaic module 2 is greater than the height of the side fixed to the bracket 1, the inclination angle of the photovoltaic module 2 increases. Conversely, when the first support member 12 and the second support member 13 are adjusted to reduce the angle between the two and the horizontal line, the change law of the inclination angle of the photovoltaic module 2 is opposite to that.

[0049] The fixing device provided in the embodiment of the present application forms a rotating connection structure between the first support member 12 and the bottom plate 11, the second support member 13 and the crimping member 14. When it is necessary to adjust the installation height or inclination of the photovoltaic module, the first support member 12 is moved so that the first rotating shaft 121 of the first support member 12 is rotated in the first sleeve 111, and the second rotating shaft 122 is rotated in the second sleeve 141. At the same time, the third rotating shaft 131 of the second support member 13 is rotated in the third sleeve 123 in the middle of the first support member 12, and the other end is moved on the bottom plate 11, and abuts against the side of different limiting protrusions 113 according to different inclination angles to complete the adjustment and fixation of the bracket height. The fixed height and inclination of the photovoltaic module 2 can be changed according to different solar illumination angles and installation requirements, so that the photovoltaic module 2 can receive light better. In addition, the bracket 1 has a simple structure and is easy to install, which effectively improves the assembly efficiency of the bracket.

[0050] Further, see Figures 1 to 5 A fourth sleeve 112 is also provided on the base plate 11, one end of the first rotating shaft 121 is rotatably connected to the first sleeve 111, and the other end of the first rotating shaft 121 is rotatably connected to the fourth sleeve 112; a fifth sleeve 142 is provided on the crimping piece 14 facing the base plate 11, one end of the second rotating shaft 122 is rotatably connected to the second sleeve 141, and the other end of the second rotating shaft 122 is rotatably connected to the fifth sleeve 142; a sixth sleeve 124 is also provided between the two ends of the first support member 12, one end of the third rotating shaft 131 is rotatably connected to the third sleeve 123, and the other end of the third rotating shaft 131 is rotatably connected to the sixth sleeve 124; the fourth sleeve 112, the fifth sleeve 142 and the sixth sleeve 124 are circumferentially provided with an insertion port 15.

[0051] Specifically, if Figures 1 to 5 As shown, one end of the first rotating shaft 121 is rotatably connected to the first sleeve 111, and the other end of the first rotating shaft 121 is rotatably connected to the fourth sleeve 112; one end of the second rotating shaft 122 is rotatably connected to the second sleeve 141, and the other end of the second rotating shaft 122 is rotatably connected to the fifth sleeve 142; one end of the third rotating shaft 131 is rotatably connected to the third sleeve 123, and the other end of the third rotating shaft 131 is rotatably connected to the sixth sleeve 124. That is, the middle part of each rotating shaft is connected to the support member, and both ends protrude from the support member, and both ends are rotatably connected to a sleeve, which improves the stability of the rotational connection between the rotating shaft and the sleeve. The fourth sleeve 112, the fifth sleeve 142 and the sixth sleeve 124 are all provided with a plug-in interface 15 for plugging the rotating shaft along the circumferential direction. Specifically, the first rotating shaft 121 extends into the fourth shaft sleeve 112 through the insertion port 15 of the fourth shaft sleeve 112, and is arranged between the fourth shaft sleeve 112 and the first shaft sleeve 111; at the same time, the second rotating shaft 122 extends into the fifth shaft sleeve 142 through the insertion port 15 of the fifth shaft sleeve 142, and is arranged between the fifth shaft sleeve 142 and the second rotating shaft 122; at the same time, the third rotating shaft 131 extends into the sixth shaft sleeve 124 through the insertion port 15 of the sixth shaft sleeve 124, and is arranged between the sixth shaft sleeve 124 and the third shaft sleeve 123. The detachable connection between each rotating shaft and the shaft sleeve can be realized, so that the bracket 11 can be detachable, which is convenient for transportation and reduces the occupied space during storage.

[0052] Further, see Figure 1 and Figure 3 The crimping piece 14 is provided with a slot 143 , and the slot 143 is used for plugging into the frame of the photovoltaic component 2 .

[0053] Specifically, if Figure 1 and Figure 3As shown in the figure, in the horizontal direction, the crimping member 14 is provided with a slot 143 for inserting the frame of the photovoltaic module 2 to fix the photovoltaic module 2, so as to maintain the stability of the fixed photovoltaic module 2 when the first support member 12 and the second support member 13 are rotated.

[0054] Further, referring to Figure 7 and Figure 8 the fixing device further includes a floating box 3; the floating box 3 is connected to the side of the bottom plate 11背离 the crimping member 14; the floating box 3 is provided with a hollow cavity 31, and the hollow cavity 31 penetrates the floating box 3 along the thickness direction of the floating box 3.

[0055] Specifically, as Figure 7 shows the schematic structural diagram of the floating box in the embodiment of the present application, Figure 8 shows the schematic structural diagram of the floating photovoltaic power generation system in the embodiment of the present application. The bottom plate 11 is connected to the upper part of the floating box 3, and the floating box 3 is provided with a hollow cavity 31 penetrating in the thickness direction. After the photovoltaic module 2 is fixed on the bracket 1, the projection of the photovoltaic module 2 on the upper part of the floating box 3 covers the hollow cavity 31. At the same time, the upper surface area of the floating box 3 is larger than the projection area of the photovoltaic module 2, and it can be used as a channel floating box for maintenance personnel to pass through, avoiding setting channel floating boxes between the floating boxes 3, saving materials and installation costs. The floating box 3 is made of UHPC (Ultra High Performance Concrete, also known as reactive powder concrete), which has high durability and mechanical properties, such as high compressive strength, flexural strength, toughness and elastic modulus, can improve the bearing capacity, ensure the strength and stability of the floating photovoltaic system, is not easy to overturn in extreme weather, and will not pollute the water body. The hollow cavity 31 structure inside the floating box 3 can give sufficient oxygen and light to the organisms in the water body, and at the same time provide a heat dissipation space on the back of the photovoltaic module 2, which is beneficial to the cooling of the surface of the photovoltaic module 2. In addition, the material cost of the floating box can be reduced.

[0056] Further, referring to Figure 7 and Figure 8 the hollow cavity 31 is at least two, and at least two of the hollow cavities 31 are arranged at intervals in the first direction and / or the second direction, and the first direction is perpendicular to the second direction.

[0057] Specifically, as Figure 7 and Figure 8 shown, at least two hollow cavities 31 are arranged at intervals inside the floating box 3 in an array structure. In the embodiment of the present application, four hollow cavities 31 are designed to form a "field" - shaped structure, and the side wall structures between different hollow cavities 31 can replace the rib structures inside the conventional floating box 3 to enhance the structural strength of the floating box 3.

[0058] Further, see Figures 8 to 10 The fixing device also includes a connecting piece 4, and the number of the buoyancy boxes 3 is at least two; both ends of the connecting piece 4 are provided with ring buckles 41; the side wall of the buoyancy box 3 is provided with a hook buckle 32, the ring buckle 41 at one end of the connecting piece 4 is movably connected to the hook buckle 32, and the ring buckle 41 at the other end of the connecting piece 4 is movably connected to the hook buckle 32 of another buoyancy box 3.

[0059] Specifically, if Fig. 9 Shows Figure 8 A partial enlarged schematic diagram of position Ⅰ of Fig.10 The schematic diagram of the structure of the connector 4 in the embodiment of the present application is shown. The side wall of the pontoon 3 is provided with a hook 32, which is an embedded part and is integrally formed with the pontoon 3. The ring buckles 41 at both ends of the connector 4 of the pontoon 3 are respectively movably connected with the hooks 32 of different pontoons 3 to realize the movable connection between adjacent pontoons 3, which can meet the swing of the pontoons 3 within a certain range in the water body, while the pontoons 3 are kept stably connected.

[0060] Further, see Figures 8 to 10 The connecting member 4 also includes a spring 42 and two bolts 43; each end of the spring 42 is connected to one of the ring buckles 41 via one of the bolts 43.

[0061] Specifically, if Figures 8 to 10 As shown, the connecting member 4 also includes a spring 42, two bolts 43 and two ring buckles 41. The bolt 43 is inserted into the ring buckle 41 from one end of the spring 42 to connect the spring 42 with the ring buckle 41. The elastic force of the spring 42 provides a relative movement space between two adjacent buoyancy boxes 3, so that the buoyancy boxes 3 can resist the tension and pressure in the horizontal position, and provide a certain buffer space for the collision between the buoyancy boxes 3, thereby reducing the damage to the buoyancy boxes 3 caused by the collision.

[0062] Further, see Figure 8 The bottom plate 11 and the buoyancy tank 3 are an integral part.

[0063] Specifically, if Figure 8 As shown, the bottom plate 11 and the pontoon 3 are an integral part, that is, the bottom plate 11 is an embedded part, which is integrally formed with the pontoon 3, thereby improving the structural strength and connection stability.

[0064] Reference Figure 8 The embodiment of the present application also provides a water photovoltaic power generation system, including a photovoltaic component 2 and a fixing device described in any of the above embodiments; the photovoltaic component 2 is connected to the crimping piece 14.

[0065] Specifically, if Figure 8 As shown, the lower frame of the photovoltaic assembly 2 is inserted into the slot 143 of the crimping member 14 to be fixed.

[0066] Further, see Figure 6 and Figure 8 The number of the base plate 11 and the bracket 1 is at least two; one side of the photovoltaic component 2 is connected to the crimping piece 14 , and the other opposite side of the photovoltaic component 2 is connected to another crimping piece 14 .

[0067] Specifically, if Figure 6 and Figure 8 As shown, a set of brackets 1 are fixed on each of the two opposite sides of the photovoltaic assembly 2, and the heights of the brackets 1 on both sides are different. The heights of the two sets of brackets 1 are adjusted respectively, and the inclination angle of the photovoltaic assembly 2 can be adjusted. At least two brackets 1 of the same height can be fixed on the same side of the photovoltaic assembly 2 to enhance the structural stability. In some embodiments, the height of the bracket 1 on the higher side is first adjusted, and the frame on one side of the photovoltaic assembly 2 is inserted into the slot 143 of the bracket 1 on the higher side, and then the height of the bracket 1 on the lower side is adjusted, and the frame on the other side of the photovoltaic assembly 2 is inserted into the slot 143 of the bracket 1 on the lower side to complete the assembly of the photovoltaic power generation system. If the inclination angle of the photovoltaic assembly 2 needs to be adjusted, the height of the bracket 1 on either side can be adjusted: raising the height of the bracket 1 on the higher side can increase the inclination angle of the photovoltaic assembly 2; lowering the height of the bracket 1 on the higher side can reduce the inclination angle of the photovoltaic assembly 2. The on-site assembly and adjustment of the bracket 1 are convenient, which is conducive to transportation.
