[0033] In related technologies, photovoltaic power stations often employ fixed structures on photovoltaic supports to connect and secure photovoltaic modules, enabling the photovoltaic supports to stably support the modules and absorb and convert light energy, thereby achieving stable operation of the photovoltaic power station. However, these fixed structures often utilize a pressure block to press against the top surface of the photovoltaic module and connect to a support seat on the top surface of the photovoltaic support, so that the fixed structure presses the photovoltaic module tightly to secure the photovoltaic module to the photovoltaic support. During assembly, construction workers are required to operate and assemble the fixed structure at a high altitude, making it more difficult to assemble the photovoltaic module on the photovoltaic support, thereby reducing the ease and efficiency of assembly of the photovoltaic power station. To address the above issues, the present application proposes a fixed structure 100.

[0034] See also Figures 1 to 9 In one embodiment of the present specification, the fixing structure 100 includes a support base 10, a pressing block 30 and a fastener 50. A fixing cavity 11 is provided in the support base 10, and the support base 10 has a bearing surface 13. The bearing surface 13 is provided with an insertion port 137 connected to the fixing cavity 11. The width of the fixing cavity 11 along the first direction and the width of the insertion port 137 along the first direction are both greater than or equal to the bottom width of the frame of the photovoltaic module 400. A pressing boss 131 is provided on the bearing surface 13, and a fastening hole 15 connected to the fixing cavity 11 is provided on the side wall of the support base 10; the pressing block 30 is provided on the bearing surface 13, and a fixing protrusion 31 is provided on one side of the pressing block 30. The fixing protrusion 31 passes through the insertion port 137 and is inserted into the fixing cavity 11; the fastener 50 is inserted into the fastening hole 15, and one end of the fastener 50 is provided in the fixing cavity 11 and presses against the fixing protrusion 31, so that the pressing block 30 and the pressing boss 131 clamp and fix the frame of the photovoltaic module 400.

[0035] In the present application, the photovoltaic bracket 200 can pre-install the support seat 10 of the fixed structure 100 at the end of the bracket body. The top surface of the support seat 10 facing away from the bracket body can be set as a relatively flat bearing surface 13. At this time, the photovoltaic component 400 can be hoisted or transported and stably placed on the bearing surface 13 of the support seat 10. The fasteners 50 of the fixed structure 100, the pressure block 30 and the support seat 10 are used to connect and cooperate to achieve the installation and fixation of the photovoltaic component 400, thereby ensuring the stable assembly of the photovoltaic component 400 on the photovoltaic bracket 200.

[0036] The pressing block 30 can be a block structure of a regular shape such as a square or an elliptical shape, or a block structure of an irregular shape. By providing a fixing protrusion 31 on the side of the pressing block 30 facing the bearing surface 13, the fixing protrusion 31 can be passed through the insertion port 137 on the bearing surface 13 and enter the fixing cavity 11. The width of the fixing cavity 11 can be set to be greater than the width of the fixing protrusion 31, thereby allowing the fixing protrusion 31 to have a certain amount of movable space in the fixing cavity 11. At this time, by connecting the fastener 50 to the support base 10 through the fastening hole 15 on the side wall of the support base 10, one end of the fastener 50 can be inserted into the fixing cavity 11, and the fastening connection of the fastener 50 on the support base 10 drives the end of the fastener 50 to move in the fixing cavity 11 against the fixing protrusion 31, so that the fixing protrusion 31 can drive the pressing block 30 to move toward the abutting boss 131.

[0037] Since the photovoltaic component 400 has a photovoltaic panel that absorbs and converts light energy and a frame that wraps the photovoltaic panel, the frame has side edges and a bottom edge connected to the side edges. When the photovoltaic component 400 is installed on the photovoltaic bracket 200, the fixing structure 100 can fix the side edges and bottom edges of the frame. At this time, the direction in which the pressing block 30 moves toward or away from the pressing boss 131 can be set as the first direction. By making the width of the fixing cavity 11 in the first direction greater than or equal to the bottom edge width of the frame of the photovoltaic component 400, and making the width of the plug interface 137 in the first direction greater than or equal to the bottom edge width of the frame of the photovoltaic component 400, the fixing protrusion 31 can have sufficient movement space at the plug interface 137 and in the fixing cavity 11, and then the pressing block 30 can be first moved a certain distance in the direction away from the pressing boss 131, so that the distance between the side of the pressing block 30 facing the pressing boss 131 and the pressing boss 131 is stably greater than or equal to the width of the bottom edge of the frame of the photovoltaic component 400, and then the photovoltaic component 400 can be placed on the support seat 10 for fixation, so that the pressing block 30 can have sufficient displacement space to avoid the placement of the photovoltaic component 400, which is beneficial to avoid interference between the photovoltaic component 400 and the pressing block 30 during installation, and ensure stable and convenient assembly of the fixed structure 100 and the photovoltaic component 400.

[0038] When the photovoltaic component 400 is placed on the support seat 10, the bottom edge of the frame of the photovoltaic component 400 can be abutted against the bearing surface 13 of the support seat 10, and the side outer wall of the frame of the photovoltaic component 400 can be abutted against the side wall of the top boss 131. At this time, one end of the fastener 50 can be used to abut the fixing protrusion 31 in the fixing cavity 11, so that the pressing block 30 can be moved toward the top boss 131 under the photovoltaic panel, and then the pressing block 30 can be abutted against the side inner wall of the frame of the photovoltaic component 400 toward the side wall of the top boss 131. Under the fastening cooperation of the fastener 50 and the support seat 10, the pressing block 30 and the top boss 131 can clamp the side edge of the frame of the photovoltaic component 400, thereby realizing the installation and fixation of the photovoltaic component 400 by the fixing structure 100, so that the photovoltaic component 400 can be stably set on the photovoltaic bracket 200, ensuring the stable operation of the photovoltaic power station.

[0039] Among them, the fastener 50 can be in the form of a bolt structure, and the fastener 50 is inserted into the fastening hole 15 and connected with the inner wall of the fastening hole 15 by threading, so as to realize the fastening and cooperation between the fastener 50 and the support seat 10; or, the fastener 50 can be in the form of a pin structure, which can be inserted into the fastening hole 15 and enter the fixing cavity 11 to abut the fixing protrusion 31, and then the pin can be abutted and fastened with the inner wall of the fastening hole 15 by using a structure such as an elastic pin or a slot pin; or, the fastener 50 can be in the form of a wedge structure In this type of structure, two or more wedge blocks can be used to fit in the fastening hole 15, and the wedge blocks can pass through the fastening hole 15 into the fixing cavity 11 to press against the fixing protrusion 31, thereby achieving the fastening and cooperation between the fastener 50 and the support seat 10. After the fastener 50 presses against the pressing block 30 and the pressing protrusion 131 to clamp and fix the side of the frame of the photovoltaic component 400, the fastener 50 can be fixed on the support seat 10 with a strap or a clip to ensure the cooperation and fixing force of the pressing block 30 and the pressing protrusion 131, thereby achieving a stable assembly of the photovoltaic component 400. In addition, when the pressing block 30 moves toward the top boss 131 to abut the side inner wall of the frame of the photovoltaic component 400, a certain distance can be set between the pressing block 30 and the supporting surface 13 at this time, and the height of the distance can be greater than or equal to the thickness of the bottom edge of the frame of the photovoltaic component 400 to avoid the pressing block 30 from colliding and interfering with the bottom edge of the frame during movement; or, a groove structure greater than or equal to the size of the bottom edge of the frame can be set on the supporting surface 13 or on the side of the pressing block 30 facing the supporting surface 13, so that when the pressing block 30 moves relative to the photovoltaic component 400, the bottom edge of the frame of the photovoltaic component 400 can be accommodated in the groove structure to avoid the movement of the pressing block 30, which is conducive to making the pressing block 30 move more stably and reliably to the side inner wall of the frame of the photovoltaic component 400, so that the pressing block 30 and the limiting boss can stably clamp and fix the photovoltaic component 400, ensuring the stable assembly of the photovoltaic component 400 on the photovoltaic bracket 200, further improving the practicality and reliability of the fixing structure 100.

[0040] In one embodiment of the present specification, the fastener 50 is inserted into the fastening hole 15 from the side wall of the support seat 10, and the fastening effect of the fastener 50 and the support seat 10 is used to press the fixing protrusion 31 to drive the pressing block 30 to move toward the pressing boss 131 on the bearing surface 13, so that the pressing block 30 abuts against the side inner wall of the frame of the photovoltaic component 400, and then the pressing boss 131 is used to abut against the side outer wall of the frame of the photovoltaic component 400, so that the pressing block 30 and the pressing boss 131 can clamp and fix the side of the frame of the photovoltaic component 400, thereby realizing the fixation of the photovoltaic component 400 by the fixing structure 100 on the photovoltaic bracket 200. Therefore, the fixed structure 100 can fix the photovoltaic component 400 by operating the fasteners 50 on the side wall of the support base 10, and there is no need for construction workers to install the fixed structure 100 above the photovoltaic component 400 that is higher than the ground. This is conducive to achieving a more convenient and reliable assembly method for the fixed structure 100, and further improving the practicality and assembly convenience of the fixed structure 100.

[0041] See Figure 2 、 Figure 3 and Figure 6 In one embodiment of the present specification, a limiting groove 311 is provided on one side of the fixing protrusion 31 , and one end of the fastener 50 is inserted into the limiting groove 311 and abuts against the inner wall of the limiting groove 311 .

[0042] In this embodiment, a limiting groove 311 can be provided on the side of the fixing protrusion 31 that contacts and abuts the fastener 50. The size of the limiting groove 311 can be greater than or equal to the size of the end of the fastener 50, so that when the fastener 50 is inserted into the fastening hole 15 and enters the fixing cavity 11, the end of the fastener 50 can be correspondingly inserted into the limiting groove 311, and the fastener 50 abuts against the inner wall of the limiting groove 311 to drive the pressing block 30 to move. Under the cooperative limiting action of the limiting groove 311 and the fastener 50, the connection stability and reliability of the fastener 50 and the fixing protrusion 31 can be further improved, which helps to prevent the fastener 50 or the fixing protrusion 31 from deviating within the fixing cavity 11 and causing a certain probability of separation of the fastener 50 from the fixing protrusion 31, thereby better ensuring the stable fixation of the fixing structure 100 to the photovoltaic module 400 and further improving the structural stability and reliability of the fixing structure 100.

[0043] In addition, by opening a limiting groove 311 on one side of the fixing protrusion 31 to cooperate with the fastener 50, it is also beneficial to better increase the contact area between the fastener 50 and the fixing protrusion 31, so that the fixing protrusion 31 can also be affected by the abutment and fixing effect of the fastener 50 in the vertical direction, preventing the fastener 50 from separating from the pressing block 30, and realizing a better fixing effect of the fixing structure 100 on the photovoltaic component 400.

[0044] See Figure 8In one embodiment of the present specification, the pressing block 30 is provided with a reinforcing rib 33 , and the reinforcing rib 33 is provided on a side of the pressing block 30 facing away from the bearing surface 13 .

[0045] In this embodiment, by providing a reinforcing rib 33 on the top of the pressing block 30, the reinforcing rib 33 can be used to increase the local wall thickness of the pressing block 30, reduce the stress concentration on the pressing block 30, and enable the pressing block 30 to better bear the pressing force applied by the fastener 50, thereby preventing the pressing block 30 from being subjected to excessive force and having a certain probability of being broken and damaged, thereby ensuring the stable clamping and fixing of the photovoltaic module 400 by the fixed structure 100, and further improving the structural stability and reliability of the fixed structure 100. Among them, the size of the reinforcing rib 33 can be gradually reduced along the moving direction of the pressing block, so that the reinforcing rib 33 can be provided with a larger structural size at the position where the fixing protrusion 31 is provided on the pressing block 30, thereby achieving a better structural reinforcement effect, while reducing the size of the reinforcing rib 33 in other areas subject to less stress, which can help reduce the overall structural material of the pressing block and play a certain effect of reducing the production cost of the fixed structure 100.

[0046] See Figure 5 and Figure 6 In one embodiment of the present specification, the bearing surface 13 is further provided with one of the positioning grooves 133 or the positioning protrusions 35 , and the side of the pressing block 30 facing the bearing surface 13 is provided with the other of the positioning grooves 133 or the positioning protrusions 35 , and the positioning protrusions 35 are inserted into the positioning grooves 133 .

[0047] In this embodiment, by providing a positioning groove 133 on the bearing surface 13 and providing a positioning protrusion 35 on the side of the pressure block 30 facing the bearing surface 13; or, by providing a positioning protrusion 35 on the bearing surface 13 and providing a positioning groove 133 on the side of the pressure block 30 facing the bearing surface 13, when the pressure block 30 is installed on the support seat 10, the positioning protrusion 35 and the positioning groove 133 are matched and plugged together to achieve the limitation of the pressure block 30 on the support seat 10, so that the pressure block 30 can achieve relatively stable directional movement when it moves on the bearing surface 13 under the action of the fastener 50, preventing the pressure block 30 from offsetting during movement and having a certain probability of detaching from the abutting photovoltaic component 400, ensuring that the fixed structure 100 clamps the photovoltaic component 400 more firmly, and further improving the structural stability and reliability of the fixed structure 100. Among them, the positioning protrusion 35 can occupy part of the structure of the pressing block 30 close to the plug-in port 137, avoiding interference and collision between the positioning protrusion 35 and the bottom edge of the frame of the photovoltaic component 400, so that the pressing block 30 can stably abut the side inner wall of the frame of the photovoltaic component 400, further improving the practicality and reliability of the fixing structure 100.

[0048] See Figure 7In one embodiment of the present specification, the bearing surface 13 is provided with two limiting flanges 17 , and the two limiting flanges 17 are arranged at a relative interval and clamp the pressing block 30 .

[0049] In this embodiment, the two limiting flanges 17 can be set to correspond to the moving path of the pressure block 30 on the bearing surface 13, and the spacing between the two limiting flanges 17 can be set to correspond to the width of the pressure block 30. Then, when the pressure block 30 is placed on the support seat 10, the two limiting flanges 17 can be used to respectively abut the opposite sides of the pressure block 30, which can play a certain role in preventing the pressure block 30 from deviating left and right on the support seat 10, thereby realizing the limited installation of the pressure block 30 on the support seat 10, which is conducive to the directional movement of the pressure block 30 on the bearing surface 13 toward the top boss 131, so that the pressure block 30 can stably abut the side inner wall of the frame of the photovoltaic component 400, thereby realizing the stable clamping and fixation of the photovoltaic component 400 by the pressure block 30 and the top boss 131, and further improving the structural stability and reliability of the fixed structure 100.

[0050] See Figure 7 In one embodiment of the present specification, the limiting flange 17 includes a first folded edge 171 and a second folded edge 173. The first folded edge 171 is connected to the bearing surface 13, and the second folded edge 173 is bent and connected to the first folded edge 171. The first folded edge 171, the second folded edge 173 and the bearing surface 13 are combined to form a slide groove, and the opposite sides of the pressure block 30 are respectively clamped in the slide grooves of the two limiting flanges 17.

[0051] In this embodiment, by utilizing the first fold edge 171 and the second fold edge 173 to enclose the bearing surface 13 to form a slide groove, the size of the slide groove can be set to correspond to the thickness size of the pressure block 30. In this way, when the pressure block 30 is placed on the support seat 10, the opposite sides of the pressure block 30 can be clamped in the slide groove formed by the two limiting flanges 17, so that the limiting flanges 17 can simultaneously abut against part of the side wall and part of the top wall of the pressure block 30, thereby achieving a more stable limiting effect on the pressure block 30, which is conducive to better preventing the pressure block 30 from offsetting during movement, ensuring the stable fixation of the fixed structure 100 to the photovoltaic component 400, and further improving the structural stability and reliability of the fixed structure 100.

[0052] See Figure 1 and Figure 4 In one embodiment of the present specification, the bottom wall of the fixing cavity 11 is tilted toward the insertion port 137 , and the bottom wall of the fixing cavity 11 is provided with a limiting rib 111 , which is used to abut against the limiting fixing protrusion 31 .

[0053] In this embodiment, when a triangular support structure is provided in the support seat 10, the bottom wall of the fixed cavity 11 can be tilted toward the plug-in port 137 to cooperate with the support structure. At this time, by providing a limiting rib 111 on the bottom wall of the fixed cavity 11, the limiting rib 111 can be used to abut the fixed protrusion 31 to prevent the fixed protrusion 31 from sliding downward along the inclined bottom wall of the fixed cavity 11 in the fixed cavity 11, thereby avoiding the pressing block 30 from being tilted on the bearing surface 13 at this time, thereby avoiding the pressing block 30 and the photovoltaic component 400 from colliding and interfering with each other, thereby achieving stable installation and fixation of the photovoltaic component 400 by the fixed structure 100, and further improving the structural stability and reliability of the fixed structure 100.

[0054] In one embodiment of the present specification, the bearing surface 13 is provided with a component retaining groove 135, and a side wall of the abutting boss 131 forms an inner side wall of the component retaining groove 135. The depth of the component retaining groove 135 is configured to be greater than or equal to the thickness of the frame of the photovoltaic module 400. Alternatively, the side of the abutting block 30 facing the bearing surface 13 is provided with a component avoidance groove 37, and the depth of the component avoidance groove 37 is configured to be greater than or equal to the thickness of the frame of the photovoltaic module 400.

The bearing surface 13 is provided with two insertion ports 137 communicating with the two fixing cavities 11. The two insertion ports 137 are located on either side of the abutting boss 131. The fixing structure 100 includes two abutting blocks 30 and two fasteners 50. The fixing protrusions 31 of the two abutting blocks 30 are respectively inserted into the two fixing cavities 11. The two fasteners 50 are respectively inserted into the two fastening holes 15 and abut against the fixing protrusions 31 of the two abutting blocks 30, so that the two abutting blocks 30 and the abutting bosses 131 clamp the frames of two adjacent photovoltaic modules 400.

The two fasteners 50 can be used to respectively press and drive the two pressing blocks 30 to move on the bearing surface 13, so that the two pressing blocks 30 can respectively move toward the two side walls of the pressing boss 131. Furthermore, during the assembly process of the photovoltaic power station, two adjacent photovoltaic components 400 can be placed side by side on the support seat 10 of the same fixed structure 100, and the two photovoltaic components 400 can be located on opposite sides of the abutting boss 131 respectively. At this time, two fasteners 50 can be used to abut and drive the two pressing blocks 30 toward the side inner walls of the two photovoltaic components 400, so that the two pressing blocks 30 can respectively cooperate with the opposite sides of the abutting boss 131 to clamp the two photovoltaic components 400, so that two photovoltaic components 400 can be fixedly installed on a fixed structure 100 at the same time, which is conducive to better realizing the compact installation arrangement of the photovoltaic components 400 on the photovoltaic bracket 200, and further improving the practicality and reliability of the fixed structure 100.
