[0013] In one embodiment, the fixed pile includes a pile body, a first protrusion, and a second protrusion;

[0014] The first protrusion and the second protrusion are connected at intervals along the axial direction of the pile body to the outer surface of the pile body. The pile body, the first protrusion and the second protrusion surround and form the mounting groove. The mounting groove is arranged along the circumference of the pile body. The connecting component is engaged in the mounting groove.

[0015] In one embodiment, the connection component includes a sleeve;

[0016] The sleeve ring is detachably fitted around the outer periphery of the fixed pile and is confined within the mounting groove.

[0017] In one embodiment, the socket ring includes two socket half-rings, which are detachably joined together to form the socket ring and fit around the outer periphery of the fixed pile.

[0018] Each of the socketed half-rings includes a half-ring body and two connecting portions connected to both sides of the half-ring body. When the two socketed half-rings are joined together and fitted onto the outer periphery of the fixed pile, the half-ring body of the two socketed half-rings is arranged around the outer periphery of the fixed pile and confined within the mounting groove, and the connecting portions of the two socketed half-rings are arranged facing each other. The connecting assembly also includes a first fastener, which is used to connect the two facing connecting portions of the two socketed half-rings.

[0019] In one embodiment, the connection component further includes a connecting ear, which is flat in shape;

[0020] The two connecting portions of the two sleeve half-rings facing each other form a connecting gap, the connecting lug extends into the connecting gap and into the mounting groove, and the connecting lug is connected between the sleeve ring and the tensioning member.

[0021] In one embodiment, the connecting lug has a plurality of first mounting holes, which are arranged at intervals along the axial direction of the fixed post;

[0022] Each of the connecting parts has a plurality of first locking holes, and when the connecting lug extends into the connecting interval, each of the first mounting holes is provided with a corresponding first locking hole;

[0043] Example 1:

[0044] like Figures 1 to 4 As shown in the figure, the underwater fixing device 100 for floating photovoltaic systems provided in this embodiment of the present invention can be used to fix photovoltaic modules located on water, at least partially above the water surface 200. The underwater fixing device 100 includes a fixing pile 10, a tensioning member 20, and a connecting assembly 30, with the connecting assembly 30 connected between the fixing pile 10 and the tensioning member 20. The fixing pile 10 can be fixed in sediment (e.g., mud, sand, etc.) at the bottom of the water. One end of the tensioning member 20 is connected to the connecting assembly 30, and the other end of the tensioning member 20 is used to connect to the beam (e.g., side beam) of the photovoltaic module. The connecting assembly 30 is circumferentially arranged around the fixing pile 10 and detachably connected to the fixing pile 10. The tensioning member 20 can be a rod-shaped component with a certain strength and elasticity, or a rope with a certain strength, such as a steel wire rope.

[0045] Using the above technical solution, the connecting component 30 is circumferentially positioned around the fixed pile 10, while the tensioning member 20 is connected to one side of the fixed pile 10. The top of the fixed pile 10 is completely exposed. When driving the fixed pile 10, the connecting component 30 will not affect the driving process, and there is no need to worry too much about hitting the connecting component, thus improving driving efficiency. By setting the connecting component 30 to the fixed pile 10 in a detachable connection, when the direction of the connecting component 30 connected to the tensioning member 20 is incorrect, such as misalignment (misalignment) between the connecting component 30 and the connection position of the edge beam, causing the tensioning member 20 to bend or twist, the fixing relationship between the connecting component 30 and the fixed pile 10 can be loosened. The connecting component 30 can be loosened relative to the fixed pile 10. By adjusting the direction of the connecting component 30 connected to the tensioning member 20, the tensioning member 20 can be straightened, reducing construction errors.

[0046] In one embodiment, the fixing pile 10 can be entirely fixed below the surface 300 of the underwater sediment. Since the fixing pile 10 is entirely fixed in the underwater sediment, it will not generate a bending moment in the water. Therefore, compared to technical solutions that partially submerge the fixing pile 10 in the water, it is not necessary to use a large and thick fixing pile, which can reduce the length and diameter of the fixing pile and save materials. Of course, in specific applications, the fixing pile 10 can also be partially fixed in the underwater sediment.

[0047] Please see Figure 3 and Figure 5 The outer periphery of the fixing pile 10 is provided with an installation groove 11, and the connecting assembly 30 is detachably installed in the installation groove 11. Specifically, the installation groove 11 has a groove wall located above the connecting assembly 30 (i.e., the first groove sidewall 112 described below). When the tensioning member 20 applies a tension force to the connecting assembly 30, the connecting assembly 30 generates an abutment force against the groove wall located above it, and correspondingly, the groove wall generates a reaction force against the connecting assembly 30. In this way, the stress strength of the connecting assembly 30 is increased, and the firmness of the underwater fixing device 100 in fixing the photovoltaic module is improved.

[0048] In one embodiment, the connecting component 30 is engaged within the mounting groove 11, meaning that the connecting component 30 contacts the two groove walls of the mounting groove 11 along the axial direction of the fixed pile 10 (i.e., the first groove sidewall 112 and the second groove sidewall 113 described below). This arrangement improves the robustness of the connection between the connecting component 30 and the fixed pile 10. Of course, in other embodiments, when the connecting component 30 is installed in the mounting groove 11, the connecting component 30 may not contact at least one of the two groove walls of the mounting groove 11 along the axial direction of the fixed pile 10.

[0049] Please see Figure 3 and Figure 5The fixing pile 10 includes a first end 12 and a second end 13 disposed opposite to each other. When the fixing pile 10 is fixed to the bottom sediment, the first end 12 is located above the second end 13. A mounting groove 11 is formed in the middle of the fixing pile 10, meaning the distance from the mounting groove 11 to the first end 12 is equal to the distance from the mounting groove 11 to the second end 13. With this arrangement, when the tensioning member 20 applies tension to the connecting assembly 30, the force-applying part of the connecting assembly 30 is located in the middle of the fixing pile 10, relative to the upper part of the fixing pile 10, thus improving the stability of the fixing pile 10 in fixing to the bottom sediment. It is understood that in other embodiments, the mounting groove 11 may also be located near the second end 13, or it may be located near the first end 12.

[0050] In one embodiment, please refer to Figure 5 The fixed pile 10 includes a pile body 14, with an installation groove 11 recessed within the pile body 14. The installation groove 11 is arranged circumferentially around the pile body 14. That is, the installation groove 11 is an annular groove, surrounding the outer periphery of the pile body 14. This arrangement is simple in structure and easy to manufacture.

[0051] In one embodiment, the fixing post 10 is configured as a cylinder. Of course, in other embodiments, the fixing post 10 may also be configured as other shapes, such as a regular prism.

[0052] Please see Figure 3 and Figure 5 The mounting groove 11 includes a bottom wall 111, a first side wall 112, and a second side wall 113. The first side wall 112 and the second side wall 113 are arranged opposite each other along the axial direction of the pile body 14, and the bottom wall 111 is connected between the first side wall 112 and the second side wall 113. The first side wall 112 is located near the first end 12, and the second side wall 113 is located near the second end 13. When the tensioning member 20 applies a tension force to the connecting assembly 30, the first side wall 112 generates a reaction force on the connecting assembly 30. In this embodiment, both the first side wall 112 and the second side wall 113 are arranged perpendicular to the bottom wall 111, that is, the angle between the first side wall 112 and the second side wall 113 and the bottom wall 111 is 90°. In other embodiments, the angle between the first side wall 112 and the second side wall 113 and the bottom wall 111 can be set to be greater than 90°, such as 135°.

[0053] In one embodiment, the connecting assembly 30 includes a sleeve ring 31, which is detachably fitted onto the outer periphery of the fixing post 10 and confined within the mounting groove 11. In specific applications, one end of the tensioning member 20 is connected to the sleeve ring 31. When the direction of the part of the sleeve ring 31 connected to the tensioning member 20 is incorrect, causing the tensioning member 20 to bend or twist, the fixing relationship between the sleeve ring 31 and the fixing post 10 can be loosened, and the sleeve ring 31 can be loosened relative to the fixing post 10. The direction of the part of the sleeve ring 31 connected to the tensioning member 20 can be adjusted so that the tensioning member 20 is straight.

[0054] In one embodiment, please refer to Figure 6 The connecting ring 31 includes two connecting half-rings 312, which are detachably joined together to form the connecting ring 31, which is then fitted onto the outer periphery of the fixed pile 10. In one embodiment, the connecting ring 31 can be a clamp, and the connecting half-rings 312 can be half-clamps, with each half-clamp detachably connected to the other half-clamp on both sides. It is understood that in other embodiments, the connecting ring 31 can also be other components, and the two connecting half-rings 312 can be hinged at one end and detachably connected at the other end.

[0055] Please see Figure 5 and Figure 6 Each sleeve half-ring 312 includes a half-ring main body 3121 and two connecting parts 3122 connected to both sides of the half-ring main body 3121. When the two sleeve half-rings 312 are mated and fitted onto the outer periphery of the fixed pile 10, the half-ring main bodies 3121 of the two sleeve half-rings 312 are arranged around the outer periphery of the fixed pile 10 and confined within the mounting groove 11, and the connecting parts 3122 of the two sleeve half-rings 312 are arranged facing each other. The connecting assembly 30 also includes a first fastener 341, which is used to connect the two facing connecting parts 3122 of the two sleeve half-rings 312. This arrangement allows the two sleeve half-rings 312 to be mated around the outer periphery of the fixed pile 10, and also facilitates the connection of the two sleeve half-rings 312. The first fastener 341 can be a bolt.

[0056] In one embodiment, please refer to Figures 3 to 6The connecting assembly 30 also includes a connecting ear 32, which is flat. Two opposing connecting portions 3122 of the two sleeved semi-rings 312 form a connecting gap 311. The connecting ear 32 extends into the connecting gap 311 and into the mounting groove 11, connecting between the sleeve ring 31 and the tensioning member 20. In specific applications, one end of the tensioning member 20 is connected to the connecting ear 32, and the sleeve ring 31 connects the fixing post 10 and the connecting ear 32. When the direction of the sleeve ring 31 connected to the connecting ear 32 is incorrect, causing the tensioning member 20 to bend or twist, the fixing relationship between the sleeve ring 31 and the fixing post 10 can be loosened. The sleeve ring 31 can then be loosened relative to the fixing post 10, and the direction of the part of the sleeve ring 31 connected to the connecting ear 32 can be adjusted to make the tensioning member 20 straight.

[0057] By extending the connecting ear 32 into the mounting groove 11, when the tensioning member 20 applies a pulling force to the connecting ear 32, the connecting ear 32 generates an abutting force against the groove wall above it (i.e., the first groove sidewall 112 mentioned above). That is, the upper end of the connecting ear 32 generates an abutting force against the first groove sidewall 112. Correspondingly, the first groove sidewall 112 generates a reaction force against the upper end of the connecting ear 32, i.e., a downward force, which increases the stress strength of the connecting ear 32 and further improves the firmness of the underwater fixing device 100 in fixing the photovoltaic module.

[0058] Please see Figure 4 and Figure 6 The connecting ear 32 has multiple first mounting holes 321, which are arranged at intervals along the axial direction of the fixing post 10. Each connecting part 3122 has multiple first locking holes 313. When the connecting ear 32 extends into the connecting interval 311, each first mounting hole 321 corresponds to a first locking hole 313. The connecting assembly 30 includes multiple first fasteners 341, each first fastener 341 passing through and connecting a first locking hole 313 and a first mounting hole 321 corresponding to the first locking hole 313. In this configuration, the connecting ear 32 and the sleeve ring 31 are connected by the first fasteners 341. In specific applications, each connecting part 3122 can be provided with multiple first locking holes 313.

[0059] In this embodiment, each half of the clamp is provided with multiple first locking holes 313 at the part where it connects with another half of the clamp. When the connecting ear 32 extends into the connecting interval 311, a first locking hole 313 is provided on each side of each first mounting hole 321. Each first fastener 341 passes through and connects a first locking hole 313 and the first mounting holes 321 on both sides of the first locking hole 313.

[0060] In practical applications, the two half-clamps are detachably connected via a first fastener 341. A connecting ear 32 is inserted into one of the connection intervals 311 formed by the two half-clamps. When the first fastener 341 connects the two half-clamps, it passes through the first mounting hole 321 so that the connecting ear 32 is connected to the clamp. The connecting ear 32 also has a second mounting hole 322. The connector at one end of the tensioner 20 is provided with a second locking hole 21. The second fastener 342 can pass through the second mounting hole 322 and the second locking hole 21 to achieve the connection between the connecting ear 32 and the tensioner 20. The tensioner 20 and / or the connecting ear 32 are rotatably connected to the second fastener 342.

[0061] Please see Figure 3 , Figure 5 and Figure 6 The connecting assembly 30 also includes multiple reinforcing plates 33, which are connected between the main body 3121 and the connecting part 3122 of the same sleeve half-ring 312 and are perpendicular to the axial direction of the sleeve ring 31. At least a portion of each reinforcing plate 33 is located within the mounting groove 11, and both ends of the sleeve ring 31 are provided with reinforcing plates 33, that is, both ends of the sleeve ring 31 along its axial direction are provided with reinforcing plates 33. With this configuration, when the tensioning member 20 applies tension to the connecting assembly 30, the reinforcing plates 33 generate abutting force against the groove wall (i.e., the aforementioned first groove sidewall 112) located above them, that is, the upper side of the reinforcing plates 33 generates abutting force against the first groove sidewall 112. Correspondingly, the first groove sidewall 112 generates a reaction force against the upper side of the reinforcing plates 33, that is, a downward force, which increases the stress strength of the reinforcing plates 33 and further improves the firmness of the underwater fixing device 100 in fixing the photovoltaic modules. By providing reinforcing plates 33 at both ends of the socket ring 31, there is no need to worry about whether the upper and lower directions are reversed when installing the socket ring 31.

[0062] In one embodiment, the reinforcing plate 33 and the first locking holes 313 are arranged alternately along the axial direction of the sleeve ring 31. This arrangement greatly improves the strength of the sleeve ring 31 and prevents the strength of the sleeve ring 31 from being reduced due to the provision of multiple first locking holes 313.

[0063] This utility model embodiment also provides a floating photovoltaic device, including a photovoltaic module and the aforementioned underwater fixing device 100 for floating photovoltaics. At least a portion of the photovoltaic module is positioned above the water surface. One end of the underwater fixing device 100 is fixed to the bottom sediment, and the other end is connected to the beam of the photovoltaic module. The underwater fixing device 100 is used to fix the photovoltaic module located above the water. By using the aforementioned underwater fixing device 100, not only can the material of the underwater fixing device 100 be saved, reducing the cost of the underwater fixing device 100, but also the construction error during installation can be reduced, and the firmness of the underwater fixing device 100 in fixing the photovoltaic module can be improved.

[0064] In one embodiment, multiple underwater fixing devices 100 are provided, with at least multiple underwater fixing devices 100 provided on opposite sides of the photovoltaic module.

[0065] Example 2:

[0066] The difference between the underwater fixing device 100 and the floating photovoltaic equipment provided in this embodiment and those in Embodiment 1 lies in the different ways in which the mounting groove 11 is formed. Specifically, in Embodiment 1, the mounting groove 11 is formed by the recess of the pile body 14; while in this embodiment, the mounting groove 11 is formed by the pile body 14, the first protrusion 15, and the second protrusion 16.

[0067] Please see Figure 3 and Figure 7 The fixing pile 10 includes a pile body 14, a first protrusion 15, and a second protrusion 16. The first protrusion 15 and the second protrusion 16 are axially spaced and connected to the outer surface of the pile body 14. The pile body 14, the first protrusion 15, and the second protrusion 16 enclose and form an installation groove 11, which is arranged circumferentially along the pile body 14. When the fixing pile 10 is fixed to the underwater sediment, the first protrusion 15 is located above the second protrusion 16 and the connecting assembly 30. When the tensioning member 20 applies a tension force to the connecting assembly 30, the connecting assembly 30 generates a resisting force against the first protrusion 15 located above it. Correspondingly, the first protrusion 15 generates a downward reaction force against the connecting assembly 30, increasing the stress strength of the connecting assembly 30 and further improving the firmness of the underwater fixing device 100 in fixing the photovoltaic module.

[0068] In one embodiment, both the first protrusion 15 and the second protrusion 16 are annular and protrude from the outer periphery of the pile body 14. It is understood that in other embodiments, the first protrusion 15 may also include a plurality of first protrusions (not shown) arranged circumferentially along the pile body 14, and the second protrusion 16 may also include a plurality of second protrusions (not shown) arranged circumferentially along the pile body 14.

[0069] In one embodiment, the pile body 14, the first protrusion 15, and the second protrusion 16 are integrally formed. This makes manufacturing convenient and quick.

[0070] Apart from the differences mentioned above, the underwater fixed device 100, the water photovoltaic equipment and its components provided in this embodiment can be designed with reference to Embodiment 1, and will not be described here again.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
