[0029] In the related art, a photovoltaic power station can use a component connector to connect two adjacent photovoltaic components so that multiple photovoltaic components can be connected and conducted to form a whole, thereby achieving the coordinated output of the electric energy generated by multiple photovoltaic components in the photovoltaic power station and ensuring the stable operation of the photovoltaic power station. However, most photovoltaic power stations use wire clamps to fix the cables of the photovoltaic components on the bottom edge of the frame of the photovoltaic components, resulting in the wiring of two adjacent photovoltaic components on the component connector and the assembly of the wire clamps mostly needing to be operated under the photovoltaic components, which in turn results in the assembly of the wire clamps on the photovoltaic components being more cumbersome and the difficulty of disassembly and maintenance being greater, reducing the assembly convenience and practicality of the photovoltaic power station. In view of the above problems, the utility model proposes a clamp 100.

[0030] See also Figures 1 to 5In one embodiment of the utility model, the clamp 100 includes a clamp seat 10, a top assembly 30, a fastener 70 and a line clip 50. The clamp seat 10 has two opposite sides, and the two sides of the clamp seat 10 are respectively provided with a limit pressure plate 115, and the limit pressure plate 115 is used to abut the top surface of the photovoltaic component 200. The clamp seat 10 is provided with a mounting cavity 10a, and the two sides of the clamp seat 10 are respectively provided with an active hole 135 connected to the mounting cavity 10a; the top assembly 30 is provided in the mounting cavity 10 a, and are respectively penetrated in two movable holes 135, the push-up assembly 30 is used to push the bottom surface of the photovoltaic component 200; the fastener 70 connects the clamp seat 10 and the push-up assembly 30, and is used to drive the push-up assembly 30 to move up and down in the installation cavity 10a, so that the push-up assembly 30 and the limiting pressure plate 115 clamp or release the photovoltaic component 200; the line clip 50 is connected to the clamp seat 10 and / or the fastener 70, and the line clip 50 is used to fix the cable 20 of the photovoltaic component 200.

[0031] It is understandable that the photovoltaic power station can use the component connector 400 to connect two adjacent photovoltaic modules 200 to achieve convenient disassembly and assembly of the photovoltaic modules 200 in the photovoltaic power station. The component connector 400 can be installed at the end of the power output cable 20 of the photovoltaic module 200. By using the electrical connection of the component connector 400, multiple photovoltaic modules 200 can be integrated into a photovoltaic module 200 array, which is conducive to better realizing the rectification output of the photovoltaic power station and ensuring the stable operation of the photovoltaic power station.

[0032] In the present application, by setting at least two clamps 100 to be clamped between two adjacent photovoltaic components 200, the cable 20 connecting the component connector 400 between the two photovoltaic components 200 can be supported and clamped in the wire clip 50 of the clamp 100, and the interval between two of the clamps 100 is set to correspond to the length of the component connector 400, so that the two clamps 100 can be used to clamp the front and rear sections of the cable 20 of the component connector 400 respectively, and then the component connector 400 can be suspended in the gap between two adjacent photovoltaic components 200 to prevent the component connector 400 from being immersed in water, thereby ensuring stable and reliable wiring between the photovoltaic components 200.

[0033] When assembling a photovoltaic power station, the photovoltaic components 200 can be arranged and installed and fixed on the photovoltaic bracket according to certain spacing requirements. At this time, the clamp 100 can first move the fastener 70 on the clamp seat 10, so that the fastener 70 drives the top component 30 to rise and move in the installation cavity 10a. The top component 30 can have a partial structure that can be movably inserted into the two movable holes 135. At this time, the fastener 70 drives the top component 30 to rise and move. Under the limiting action of the movable holes 135, this part of the structure of the top component 30 can be retracted to avoid the installation of the clamp seat 10, so that the clamp seat 10 can be stably placed in the gap between adjacent photovoltaic components 200 from above the photovoltaic components 200, and then after the clamp seat 10 is placed in place, the limiting pressure plates 115 on both sides of the clamp seat 10 can be respectively pressed onto the top surfaces of the two adjacent photovoltaic components 200. At this time, the two movable holes 135 on both sides of the clamp 10 can be exposed below the bottom surface of the photovoltaic component 200. By moving the fastener 70 to drive the top component 30 to move downward in the installation cavity 10a, the partial structure of the top component 30 passing through the two movable holes 135 can be moved to the bottom of the two photovoltaic components 200 and abut the bottom surfaces of the two photovoltaic components 200 under the limiting action of the movable holes 135. Then, under the supporting and fastening action of the fastener 70, the limiting pressure plate 115 and the top component 30 can be stably clamped and fixed between two adjacent photovoltaic components 200, thereby realizing the convenient assembly of the clamp 100 on the photovoltaic component 200, and effectively improving the assembly convenience and practicality of the clamp 100. Among them, the line card 50 can be connected to the clamp seat 10 by means of fixing parts such as bolts and clips; or the line card 50 and the clamp seat 10 can be set as an integrated structure; or, the line card 50 can be connected to the fastener 70, and the line card 50 can be protruded on one side of the clamp seat 10, so that after the clamp 100 is installed and fixed between two adjacent photovoltaic components 200, the cable 20 of the photovoltaic component 200 can be clamped to the line card 50 of the clamp 100, so that the clamp 100 can store and support the component connector 400 and the output cable 20 of the photovoltaic component 200, thereby ensuring the stable and reliable operation of the photovoltaic power station.

[0034] The technical solution of the utility model can drive the top assembly 30 to move up and down in the installation cavity 10a by using the fastener 70 on the clamp seat 10, so that the limiting pressure plate 115 of the clamp seat 10 and the part of the structure of the top assembly 30 through the movable hole 135 can clamp and fix two adjacent photovoltaic components 200, so as to realize the installation and fixation of the clamp 100 on the photovoltaic power station, so that the cable 20 of the photovoltaic component 200 can be stably clamped and fixed on the wire clamp 50 of the clamp 100, and the clamp 100 can stably store and support the cable 20 of the photovoltaic component 200 and the component connection line. Then, the clamp 100 can be installed from above the photovoltaic component 200, and the overall assembly of the clamp 100 can be completed by moving the fastener 70 on the clamp seat 10, which can effectively reduce the assembly difficulty and assembly process of the clamp 100, realize the convenient installation of the clamp 100, improve the assembly efficiency of the photovoltaic power station, and further improve the practicality and reliability of the clamp 100.

[0035] See also Figures 2 to 5 In an embodiment of the utility model, the clamping seat 10 includes a first seat body 11, a second seat body 13 and a connecting member 15. Limiting pressure plates 115 are respectively provided on both sides of the first seat body 11, and the first seat body 11 is provided with a first mounting hole 113; a mounting cavity 10a is provided in the second seat body 13, and movable holes 135 are respectively provided on both sides of the second seat body 13. The second seat body 13 is provided with a second mounting hole 133 connected to the mounting cavity 10a, and the second mounting hole 133 is arranged opposite to the first mounting hole 113; the connecting member 15 connects the first seat body 11 and the second seat body 13.

[0036] In this embodiment, by using the connecting member 15 to connect the first base body 11 and the second base body 13, the connecting member 15 can form a certain cavity structure between the first base body 11 and the second base body 13, and by arranging the first mounting hole 113 of the first base body 11 and the second mounting hole 133 of the second base body 13 relatively to each other, the cavity between the first base body 11 and the second base body 13 can be connected to the first mounting hole 113 and the second mounting hole 133. At this time, the fastener 70 can pass through the first mounting hole 113 and the second mounting hole 133 on the first seat body 11 to enter the mounting cavity 10a, and connect to the push-up assembly 30 in the mounting cavity 10a, and then the fastener 70 can be operated to move on the first seat body 11, so that the fastener 70 drives the push-up assembly to move up and down in the mounting cavity 10a, ensuring that the push-up assembly 30 can stably avoid the gap between the clamp seat 10 and the push-up assembly 30 cooperates with the limiting pressure plate 115 to clamp the photovoltaic assembly 200, which is conducive to more conveniently operating the fastener 70 from above the photovoltaic assembly 200, realizing the installation and fixation of the clamp 100 on the photovoltaic assembly 200, and further improving the assembly convenience and reliability of the clamp 100.

[0037] Among them, the first seat body 11 can form a groove structure on the side facing away from the second seat body 13, so that the first mounting hole 113 is set on the bottom wall of the groove structure. At this time, the fastener 70 can connect the fastening clamp 10 and the top assembly 30 so that the limiting pressure plate 115 and the top assembly 30 clamp and fix the two adjacent photovoltaic components 200, and then be stored in the groove structure of the first seat body 11, which is beneficial to avoid the fastener 70 from protruding on the surface of the photovoltaic component 200 after installation, thereby further improving the aesthetics and practicality of the clamp 100.

[0038] In the embodiment of the present utility model, the inner wall of the first mounting hole 113 is provided with an internal thread, the outer periphery of the fastener 70 is provided with an external thread, and the fastener 70 is threadedly matched with the first mounting hole 113 .

[0039] In this embodiment, the fastener 70 can adopt a bolt structure setting, or the fastener 70 can be made to adopt a special-shaped cylindrical structure setting with external threads on a part of the outer circumference, so that the fastener 70 can be connected to the clamp seat 10 by threaded cooperation with the first mounting hole 113, and the fastening and adjustment function of the fastener 70 and the clamp seat 10 can be achieved by threaded cooperation between the fastener 70 and the first mounting hole 113, so that the fastener 70 can be screwed on the clamp seat 10 to make the fastener 70 move up and down in the installation cavity 10a, and then one end of the fastener 70 can be connected to the push-up assembly 30 and pull the push-up assembly 30 to move up and down in the installation cavity 10a, and the fastener 70 can stably cooperate with the clamp seat 10 to tighten and ensure that the push-up assembly 30 and the limiting pressure plate 115 clamp and fix the photovoltaic assembly 200, further improving the operational convenience and reliability of the clamp 100.

[0040] Among them, the fastener 70 can be provided with a limiting convex ring or a limiting groove on the outer periphery of the end portion, and a limiting groove or a limiting convex ring can be correspondingly provided on the inner wall of the hole in the push-up assembly 30 for the fastener 70 to pass through, so that the fastener 70 can be connected to the push-up assembly 30 under the matching clamping action of the limiting convex ring and the limiting groove, and the fastener 70 and the push-up assembly 30 can be relatively rotatable. Furthermore, in the process of threaded matching connection between the fastener 70 and the first seat body 11, the inner wall of the movable hole 135 can be used to limit part of the structure of the push-up assembly 30, which can prevent the push-up assembly 30 from being driven to rotate by the fastener 70, so that the push-up assembly 30 can be stably driven by the fastener 70 to move up and down in the installation cavity 10a, thereby ensuring the stable and reliable operation of the clamp 100.

[0041] See also Figure 3 to Figure 4 In the embodiment of the present invention, the connecting member 15 is an elastic structure, and the first base body 11 and the second base body 13 can be relatively movably arranged.

[0042] In this embodiment, the connecting member 15 can be an elastic structure such as a spring, elastic silicone, elastic rubber, etc., and the first seat body 11 and the second seat body 13 are connected by using the connecting member 15 with a certain elasticity. During assembly, the construction worker can connect the fastener 70 to the top assembly 30 and then pull the fastener 70 upward, so that the fastener 70 drives the top assembly 30 and the second seat body 13 to move closer to the first seat body 11. At this time, the connecting member 15 is elastically deformed by the force applied to it by the second seat body 13. At this time, under the action of the fastener 70, part of the structure of the top assembly 30 can be stably driven to move in the installation cavity 10a, so that the maximum outer diameter of the clamp 100 on the second seat body 13 can be stably smaller than the gap setting between the two adjacent photovoltaic components 200, ensuring that the clamp 100 can stably pass through the gap between the two adjacent photovoltaic components 200 for installation. When the clamp 10 is stably placed in the gap between two adjacent photovoltaic modules 200, the construction workers can release the force on the fastener. At this time, the force applied to the connecting member 15 can be released to restore the elastic deformation of the connecting member 15, and the connecting member 15 can better push the second seat body 13 to move downward under the action of the elastic force, which is conducive to making the movable hole 135 better exposed under the photovoltaic module 200 as the second seat body 13 descends, and the second seat body 13 drives the fastener 70 to move downward a certain distance through the abutting assembly 30, reducing the installation length of the fastener 70 moving downward, so that the fastener 70 can move a shorter distance to drive the abutting assembly to move downward in the installation cavity 10a, so that part of the structure of the abutting assembly 30 can stably pass through the movable hole 135 to abut the bottom surface of the photovoltaic module 200, thereby realizing a more convenient installation of the clamp 100 and further improving the operational convenience and practicality of the clamp 100.

[0043] In the embodiment of the present utility model, the first base body 11, the second base body 13 and the connecting member 15 are an integral structure.

[0044] In this embodiment, the first seat body 11, the second seat body 13 and the connecting member 15 can be manufactured by 3D printing technology or casting technology, which is conducive to forming the clamp seat 10 into an integrated structure with higher structural strength, so that the clamp seat 10 can more stably support the fastener 70, so that under the coordinated tightening action of the fastener 70 and the clamp seat 10, the limiting pressure plate 115 and the supporting assembly 30 can more stably clamp the photovoltaic assembly 200, better improve the service life of the clamp 100 in the photovoltaic power station, and further improve the structural stability and reliability of the clamp 100.

[0045] See also Figures 3 to 5In an embodiment of the utility model, the supporting assembly 30 includes a traction block 33 and two supporting blocks 31. The traction block 33 is movably disposed in the installation cavity 10a and is connected to the fastener 70. The two supporting blocks 31 are rotatably connected to the traction block 33 and are respectively penetrated through the two movable holes 135. The supporting blocks 31 are used to support the bottom surface of the photovoltaic assembly 200.

[0046] In this embodiment, the resisting assembly 30 can respectively rotatably connect one end of the two resisting blocks 31 to the traction block 33, and respectively penetrate two movable holes 135 facing the opposite sides of the traction block 33, so that when the fastener 70 drives the traction block 33 to move up and down, the movable holes 135 can be used to limit the resisting block 31, so that the clamping seat 10, the traction block 33 and the resisting block 31 form a certain lever structure, and then the traction block 33 can be used to move up and down in the installation cavity 10a to drive the resisting block 31 is moved to change the length of the part of the structure of the abutting block 31 that passes through the movable hole 135 and is exposed on the outer wall of the clamp seat 10, so that the abutting block 31 can retract to avoid the installation of the clamp seat 10, or the abutting block 31 moves part of the structure through the movable hole 135 to below the bottom surface of the photovoltaic component 200 to abut the photovoltaic component 200, so that the clamp 100 can be stably clamped and fixed on the photovoltaic component 200 by using the abutting block 31 and the limiting pressure plate 115, thereby further improving the structural stability and reliability of the clamp 100.

The fastener 70 can make the avoidance section connecting the first connecting section and the second connecting section adopt a structure with a smooth outer periphery, and make the diameter of the avoidance section smaller than the diameter of the second connecting section. At this time, by setting a mounting blind hole on the traction block 33, and making the mounting blind hole sequentially provided with a threaded section and a limiting section along the hole entry direction, the threaded section can be provided with an internal thread that matches the external thread of the second connecting section, and the aperture of the threaded section corresponds to the size of the second connecting section, and the limiting section can be set close to the blind plate end of the mounting blind hole, and the aperture and hole depth of the limiting section are larger than the threaded section. The aperture and depth of the segment are set so that the second connecting segment of the fastener 70 can be threadedly connected and cooperated with the threaded segment, and as the fastener 70 rotates, the second connecting segment can pass through the threaded segment and enter the limiting segment. At this time, a part of the avoidance segment of the fastener 70 can be passed through the threaded segment, and the outer thread edge of the second connecting segment is abutted against the inner thread edge of the threaded segment so that the fastener and the traction block 33 are connected to form a whole. At the same time, since the aperture of the limiting segment is larger than the outer diameter of the second connecting segment, the fastener 70 can be set to rotate relative to the traction block 33 at this time.
