[0041] This utility model discloses a photovoltaic module testing device, which can perform torsional force testing and flip-over force testing on photovoltaic modules to improve the accuracy of these tests.

[0042] In this embodiment of the invention, the photovoltaic module to be tested includes a photovoltaic module 110 and a tracking bracket 111 connected to the photovoltaic module 110. The tracking bracket 111 is connected to the middle region of the photovoltaic module 110. The tracking bracket 111 can adjust its posture according to factors such as time, sunlight, and the direction of the sun, so that the photovoltaic module 110 faces the direction of sunlight, thereby absorbing more sunlight and improving the photoelectric conversion efficiency of the photovoltaic module.

[0043] like Figures 1 to 5 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention includes a first support 10, a second support 20, a clamping component 30, and a control component. A tracking support 111 is connected to the first support 10 to support the tracking support 111, and the tracking support 111 is used to fix the photovoltaic module 110.

[0044] It should be noted that, in this embodiment of the present invention, the tracking bracket 111 can be snapped onto the first bracket 10, and the tracking bracket 111 can be detachably connected to the first bracket 10 by bolts. Of course, the above are merely individual examples of the specific ways in which the tracking bracket 111 is connected to the first bracket 10, and are not intended to limit the present invention. In practical applications, those skilled in the art can configure the specific way in which the tracking bracket 111 is connected to the first bracket 10 as needed.

[0045] like Figure 1As shown, in this embodiment of the invention, the second support 20 is spaced apart from the first support 10, and the clamping component 30 is vertically and flexibly connected to the second support 20. The clamping component 30 clamps the photovoltaic module 110 near its edge. The clamping component 30 is electrically connected to a control component, which can drive the clamping component 30 to move up and down. The up and down movement of the clamping component 30 can cause the photovoltaic module 110 to sway up and down, thereby simulating the motion state of the photovoltaic module 110 under wind load, so as to perform torsional force test and overturning force test on the photovoltaic module 110.

[0046] It should be noted that, in this embodiment of the present invention, a slide rail 70 can be provided on the second bracket 20, the slide rail 70 extending along the height direction of the second bracket 20, and the slider 71 is slidably connected to the slide rail 70, so that the slider 71 can slide relative to the slide rail 70 along the height direction of the second bracket 20. The clamping component 30 is connected to the slider 71, so that the slider 71 can drive the clamping component 30 to rise and fall along the height direction of the second bracket 20, so that the clamping component 30 can be lowered to be flush with the photovoltaic module 110 and clamp the area of ​​the photovoltaic module 110 near the edge.

[0047] Of course, in this embodiment of the invention, there are no excessive restrictions on the specific manner in which the clamping component 30 is vertically and flexibly connected to the second bracket 20. In practical applications, those skilled in the art can design it accordingly.

[0048] In the photovoltaic module testing device disclosed in this embodiment of the utility model, a tracking bracket 111 connected to the photovoltaic module 110 is fixed by a first bracket 10, and a clamping component 30 is vertically connected to a second bracket 20. The photovoltaic module 110 is clamped by the clamping component 30, and the control component can drive the clamping component 30 to move up and down, causing the photovoltaic module 110 to swing up and down. This simulates the motion state of the photovoltaic module 110 under wind load, so as to perform torsional force test and overturning force test on the photovoltaic module 110, making the torsional force test results and overturning force test results of the photovoltaic module 110 more accurate.

[0049] Furthermore, the photovoltaic module testing device disclosed in this utility model can not only realize dynamic load testing of photovoltaic modules, but also static load testing and non-uniform load testing of photovoltaic modules, making the photovoltaic module test results more accurate and reliable.

[0050] Optionally, such as Figure 1 and Figure 2 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention also includes a counterweight 50, wherein the counterweight 50 is vertically connected to the first support 10, and the counterweight 50 is used to press on the surface of the photovoltaic module 110, or to detach from the surface of the photovoltaic module 110.

[0051] like Figure 1 and Figure 2 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention also includes a counterweight 50, which is vertically and flexibly connected to the first support 10. When performing torsional force testing or overturning force testing on the photovoltaic module, the counterweight 50 can be lowered to press against the surface of the photovoltaic module 110, so as to provide a certain load on the photovoltaic module 110 through the counterweight 50, so as to simulate the wind load on the surface of the photovoltaic module 110 when the photovoltaic module 110 is used outdoors, making the torsional force test results or overturning force test results of the photovoltaic module 110 more accurate.

[0052] Before or after the torsional force test or the overturning force test of the photovoltaic module 110, the counterweight 50 can be lifted to a position detached from the surface of the photovoltaic module 110, so that the photovoltaic module 110 can be installed on the first bracket 10, or so that the photovoltaic module 110 can be removed from the first bracket 10.

[0053] It should be noted that the counterweight 50 in this embodiment of the present invention can be a pressure block, which may include one or more. When there are multiple pressure blocks, they are spaced apart and are all used to press against the surface of the photovoltaic module 110.

[0054] Optionally, such as Figure 1 and Figure 2 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention also includes a lifting frame 60, wherein the lifting frame 60 is movably connected to the first support 10, and the lifting frame 60 is used to connect the counterweight 50 to drive the counterweight 50 to rise and fall.

[0055] like Figure 1 and Figure 2 As shown in this embodiment of the invention, the lifting frame 60 is vertically connected to the first support 10, and the counterweight 50 is connected to the lifting frame 60, making the counterweight 50 vertically connected to the first support 10. That is, the lifting frame 60 has a connecting portion that can connect to the counterweight 50. Along the height direction of the first support 10, the lifting frame 60 can rise and fall relative to the first support 10, thereby causing the counterweight 50 to rise and fall relative to the first support 10, allowing the counterweight 50 to press against the surface of the photovoltaic module 110, or to detach from the surface of the photovoltaic module 110.

[0056] For example, in this embodiment of the present invention, a slide rail can be provided on the first support 10, the slide rail extending along the height direction of the first support 10, a slider slidably connected to the slide rail, and a lifting frame 60 fixedly connected to the slider. The slider slides relative to the slide rail along the height direction of the first support 10, thereby driving the lifting frame 60 to rise and fall along the height direction of the first support 10.

[0057] Of course, the above are merely individual examples of the specific ways in which the lifting frame 60 is flexibly connected to the first support 10, and are not intended to limit the present invention. In practical applications, technicians can configure the specific ways in which the lifting frame 60 is flexibly connected to the first support 10 as needed.

[0058] Optionally, such as Figure 1 and Figure 3 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention also includes a slide rail 70 and a slider 71. The slide rail 70 extends along the first direction X and is connected to the second support 20. The slider 71 is slidably connected to the slide rail 70, and the clamping component 30 is telescopically connected to the slider 71 along the second direction Y. The first direction X is the height direction of the second support 20, and the second direction Y intersects the first direction X.

[0059] like Figure 1 and Figure 3 As shown in the embodiment of this utility model, a slide rail 70 is connected to the second bracket 20. The slide rail 70 extends along the height direction of the second bracket 20. A slider 71 is slidably connected to the slide rail 70. A clamping component 30 is connected to the slider 71 so that the slider 71 drives the clamping component 30, so that the clamping component 30 can be raised and lowered relative to the second bracket 20, so as to clamp the edge area of ​​the photovoltaic module 110 through the clamping component 30.

[0060] It should be noted that in this embodiment of the present invention, the clamping component 30 is telescopically connected to the slider 71 along the second direction Y. When the clamping component 30 is lowered to be flush with the photovoltaic module 110, the clamping component 30 can extend along the second direction Y to the edge region of the photovoltaic module 110, so as to clamp the edge region of the photovoltaic module 110 by contacting the component 30.

[0061] For example, in this embodiment of the present invention, the clamping component 30 can be slidably connected to the slider 71 along the second direction Y, so that the clamping component 30 is retractable relative to the slider 71 along the second direction Y.

[0062] In this embodiment of the invention, the slide rail 70 extends along the height direction of the second bracket 20 and is connected to the second bracket 20. The slider 71 is slidably connected to the slide rail 70, and the clamping assembly 30 is telescopically connected to the slider 71 along the second direction Y. The slider 71 slides relative to the slide rail 70 so that the clamping assembly 30 is flush with the photovoltaic module 110. When the clamping assembly 30 is flush with the photovoltaic module 110, the clamping assembly 30 can extend along the second direction Y to the edge area of ​​the photovoltaic module 110 to clamp the edge area of ​​the photovoltaic module 110. Then, by controlling the component to drive the slider 71 to move up and down, the clamping assembly 30 is driven to move up and down, causing the photovoltaic module 110 to swing up and down. This simulates the motion state of the photovoltaic module 110 under wind load, so as to perform torsional force test and overturning force test on the photovoltaic module 110, making the torsional force test results and overturning force test results of the photovoltaic module 110 more accurate.

[0063] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly 30 in this embodiment of the present invention includes a clamping member 31 and a fixing member 32. The clamping member 31 is telescopically connected to the slider 71 along the second direction Y. The clamping member 31 is provided with a receiving cavity 311, which is used to receive the area of ​​the photovoltaic module 110 near the edge. The fixing member 32 is telescopically connected to the clamping member 31 along the first direction X. The fixing member 32 is used to fix the area of ​​the photovoltaic module 110 near the edge.

[0064] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly 30 in this embodiment of the present invention includes a clamping member 31 and a fixing member 32. The clamping member 31 is telescopically connected to the slider 71 along the second direction Y. The clamping member 31 has a receiving cavity 311 extending along the second direction Y, and the receiving cavity 311 has an opening in the second direction Y. When the clamping member 31 is flush with the photovoltaic module 110, the clamping member 31 extends towards the photovoltaic module 110 along the second direction Y. The area of ​​the photovoltaic module 110 near the edge can extend into the receiving cavity 311 through the opening, so as to limit and fix the photovoltaic module 110 through the receiving cavity 311.

[0065] In this embodiment of the invention, the fixing member 32 is retractably connected to the clamping member 31 along the first direction X. After the photovoltaic module 110 is housed in the receiving cavity 311, the fixing member 32 can extend along the first direction X until it abuts against the surface of the photovoltaic module 110, thereby further fixing the photovoltaic module 110 through the fixing member 32.

[0066] It should be noted that the fixing member 32 in this embodiment of the present invention can be an adsorption member, such as a suction cup. The fixing member 32 in this embodiment of the present invention can also be a fixing block. In this embodiment of the present invention, no excessive restrictions are placed on the specific structure of the fixing member 32. In practical applications, those skilled in the art can choose according to their needs.

[0067] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping member 31 in this embodiment of the present invention has a first side plate 312 and a second side plate 313 spaced apart along the first direction X, and an end plate 314 connected between the first side plate 312 and the second side plate 313. The first side plate 312, the end plate 314 and the second side plate 313 surround to form an accommodating cavity 311. The fixing member 32 includes a first suction cup 321 and a second suction cup 322. The first suction cup 321 is movably connected to the first side plate 312 along the first direction X and is used to adsorb the first surface of the photovoltaic module 110. The second suction cup 322 is movably connected to the second side plate 313 along the first direction X and is used to adsorb the second surface of the photovoltaic module 110.

[0068] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping member 31 in this embodiment of the present invention includes a first side plate 312, a second side plate 313, and an end plate 314. The first side plate 312 and the second side plate 313 are spaced apart along a first direction X, and the end plate 314 is connected between the first side plate 312 and the second side plate 313, thereby forming a receiving cavity 311 by the first side plate 312, the end plate 314, and the second side plate 313. This arrangement causes the receiving cavity 311 to extend along a second direction Y and have an opening in the second direction Y. The edge region of the photovoltaic module 110 can extend into the receiving cavity 311 through the opening to fix the photovoltaic module 110.

[0069] like Figure 1 , Figure 3 and Figure 4As shown, the fixing member 32 in this embodiment of the present invention includes a first suction cup 321 and a second suction cup 322. The first suction cup 321 is movably connected to the first side plate 312 along the first direction X, and the second suction cup 322 is movably connected to the second side plate 313 along the first direction X. When the photovoltaic module 110 is housed in the receiving cavity 311, the first suction cup 321 extends along the first direction X toward the first surface of the photovoltaic module 110 and adheres to the first surface of the photovoltaic module 110, and the second suction cup 322 extends along the first direction X toward the second surface of the photovoltaic module 110 and adheres to the second surface of the photovoltaic module 110. Thus, the photovoltaic module 110 can be further fixed by the first suction cup 321 and the second suction cup 322, preventing the photovoltaic module 110 from detaching from the receiving cavity 311.

[0070] Optionally, such as Figure 3 and Figure 4 As shown, the photovoltaic module testing device in this embodiment of the present invention also includes a connecting rod 80, which extends along the second direction Y.

[0071] like Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the connecting rod 80 extends along the second direction Y, and one end of the connecting rod 80 is fixedly connected to the slider 71. It can be understood that "one end of the connecting rod 80 is fixedly connected to the slider 71" means that one end of the connecting rod 80 is fixedly disposed relative to the slider 71. Exemplarily, one end of the connecting rod 80 is integrally formed with the slider 71. One end of the connecting rod 80 is detachably connected to the slider 71 by bolts.

[0072] like Figure 3 As shown, in this embodiment of the invention, the connecting rod 80 is provided with a groove 81 extending along the second direction Y, and the extension direction of the groove 81 is the same as the extension direction of the connecting rod 80. The end 314 of the clamping member 31 is slidably connected in the groove 81, so that the end 314 can drive the clamping member 31 to slide along the second direction Y. When the photovoltaic module 110 is flush with the clamping member 31, the clamping member 31 can extend along the second direction Y to a position close to the photovoltaic module 110 to clamp the photovoltaic module 110.

[0073] Optionally, such as Figure 1 As shown, the control component in this embodiment of the present invention includes a control module 41 and a first motor 42. The first motor 42 is electrically connected to the control module 41 and connected to the slider 71. The first motor 42 is used to receive instructions from the control module 41 and drive the slider 71 to slide relative to the slide rail 70 along the first direction X based on the instructions.

[0074] like Figure 1 As shown, in this embodiment of the present invention, the first motor 42 is disposed on the top of the second bracket 20 and connected to the slider 71 so that the slider 71 can be driven by the first motor 42, so that the slider 71 can slide relative to the slide rail 70 along the first direction X, thereby driving the clamping member 31 to slide along the first direction X, so that the clamping member 31 can reach a position flush with the photovoltaic module 110.

[0075] The photovoltaic module testing device disclosed in this embodiment of the present invention further includes a control module 41, which is electrically connected to a first motor 42. The control module 41 enables the first motor 42 to receive commands from the control module 41, including but not limited to driving the first motor 42 to rotate or driving the first motor 42 to stop rotating. That is, the first motor 42 can rotate according to the received command to drive the slider 71 to slide relative to the slide rail 70 along a first direction X. The first motor 42 can also stop rotating according to the received command to prevent the slider 71 from sliding relative to the slide rail 70.

[0076] Optionally, such as Figure 3 and Figure 5 As shown, the photovoltaic module testing device disclosed in this embodiment of the present invention also includes a support plate 90, wherein the support plate 90 is spaced apart from the first bracket 10; the second bracket 20 has a support part 21, which is connected to the support plate 90.

[0077] like Figure 3 and Figure 5 As shown, in this embodiment of the present invention, the support plate 90 and the first bracket 10 are spaced apart, and the second bracket 20 is disposed on the support plate 90 so as to support the second bracket 20 through the support plate 90, making the second bracket 20 more stable.

[0078] In this embodiment of the present invention, a support portion 21 may be provided at the end of the second bracket 20 near the support plate 90, and the support portion 21 may be connected to the support plate 90 so as to connect the second bracket 20 to the support plate 90 through the support portion 21, thereby fixing the second bracket 20 and making the second bracket 20 more stable.

[0079] For example, in this embodiment of the present invention, the support portion 21 includes a base and a support leg disposed on the side of the base near the support plate 90. The support leg is telescopically connected to the base along a first direction X. Adjusting the distance between the support leg and the base along the first direction X improves the stability of the second bracket 20.

[0080] The support legs may include multiple legs, which are spaced apart and are all telescopically connected to the base on the side near the support plate 90 along the first direction X.
