Description

Technical Field

[0001] This invention relates to the field of solar cell technology, and in particular to a detection system and method based on solar cells. Background Technology

[0002] A solar cell is a thin, photovoltaic semiconductor wafer that directly generates electricity using sunlight. Also known as a "solar chip" or "photovoltaic cell," it can instantly output voltage and, in the presence of a circuit, generate current, provided it receives sufficient illumination. Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect.

[0003] Solar cells are typically installed over large areas in open outdoor spaces. However, different environments can lead to different problems that need to be addressed during their operation. In particular, in sandy environments (such as deserts), because solar cells are installed at an angle, sand tends to accumulate at the bottom of the solar cell. The pressure distribution of sand on the solar cell varies depending on the installation angle.

[0004] Chinese patent CN218036158U discloses an outdoor photovoltaic power generation module pressure resistance quality testing device. This testing device mainly applies pressure to the solar panel by using fluid in the pressure chamber to simulate the pressure testing process of the photovoltaic power generation module. However, the installation angle of all solar panels cannot be the same due to the differences in sunshine duration in different regions. This means that solar panels in different regions need to be adjusted to different angles according to local conditions. Under different installation angles, the force distribution on the solar panel will be different. However, the technical solution disclosed in the existing patent cannot solve the above problems.

[0005] Therefore, it is necessary to provide a detection system and method based on solar cells that can achieve self-regulating simulation detection. Summary of the Invention

[0006] The purpose of this invention is to provide a detection system and method based on solar cells to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A solar cell-based detection system includes a base, a positioning mechanism, an adjustment mechanism one, and an adjustment mechanism two. The base is equipped with a control panel with a PLC controller, and a fixing frame is mounted on the base. Two symmetrically arranged shaft seats are provided on the base.

[0009] The positioning mechanism is rotatably mounted between two bearing seats via a shaft connection. Support platforms are provided on opposite side walls of the positioning mechanism, and a solar panel is placed between the support platforms on both sides. Elastically adjustable clamps are also provided on both sides of the solar panel.

[0010] The adjustment mechanism includes an adjustment seat, a vertical plate, a lower pressure member, and a lifting seat. The adjustment seat slides along the length of the fixed frame. Two vertical plates are provided and symmetrically installed on the bottom wall of the adjustment seat. Two lifting seats are provided and move along the vertical direction of the fixed frame respectively. The lower pressure member is located between the adjustment seat and the lifting seat. An auxiliary member is elastically provided on the lower pressure member. A rotating shaft is slidably provided on the auxiliary member. The rotating shaft elastically slides between the inner walls of the vertical plates.

[0011] The second adjustment mechanism includes an adjustment seat and an adjustment handle. A fixing groove is provided on the base. The second adjustment seat slides along the inner wall of the fixing groove. There are two adjustment handles. One end of the adjustment handle is connected to the side wall of the second adjustment seat, and the other end of the adjustment handle is connected to the positioning mechanism. The length of the adjustment handle is adjustable.

[0012] Several counterweight rollers are installed above the solar panel. The counterweight rollers are located between the pressing component and the auxiliary component. In addition, the adjusting seat one and the adjusting seat two move synchronously and in the same direction for adjustment.

[0013] In one embodiment, a rod is provided between the side walls of the fixing frame, and a transparent baffle is slidably provided on the rod. The baffle and the rod can be connected and fixed together by fastening screws.

[0014] A screw is rotatably installed between the side walls of the fixed frame. The screw is installed along the length of the fixed frame, and one end of the screw passes through the fixed frame and rotatably contacts its inner wall. The screw passes through the middle of the adjusting seat and engages with it through a threaded transmission.

[0015] In one embodiment, the positioning mechanism includes a clamping seat 1 and a clamping seat 2. The clamping seat 1 has two connecting shafts and two connecting members respectively arranged on the side wall facing the clamping seat 2. The connecting members are arranged in a strip-shaped structure. The other end of the connecting shaft always slides and adjusts along the inner wall of the clamping seat 2. An outer groove is opened on both side walls of the clamping seat 2. An adjusting gear is rotatably arranged in the outer groove. One end of the connecting member is provided with several tooth grooves that mesh with the adjusting gear. A guide bar is also provided on the side wall of the connecting member facing the connecting shaft. A guide groove matching the guide bar is opened along the length direction on one side inner wall of the outer groove. The guide bar slides along the inner wall of the guide groove and the two are always in contact.

[0016] In one embodiment, a second through hole is provided on the vertical plate. The second through hole is arranged vertically, with its top end being a flat surface and its bottom end being an arc surface. A top block is slidably arranged between the inner walls of the second through hole. The bottom surface of the top block is an arc surface, and a guide shaft is provided on the top end of the top block. The top end of the guide shaft always slides between the inner walls of the vertical plate, and an adjusting spring is sleeved on the guide shaft. The top end of the adjusting spring is fixed to the top end of the second through hole, and the bottom end of the adjusting spring is fixed to the top surface of the top block. The rotating shaft matches the arc surface.

[0017] In one embodiment, the pressing component includes a connecting rod, a first connecting end, and a second connecting end. The connecting rod is fixed between the first connecting end and the second connecting end. The first connecting end is connected to the side wall of the adjusting seat and the vertical plate via a shaft. A fixed shaft is provided in the middle of one side wall of the lifting seat. A vertically arranged through hole is provided on the fixed frame. The fixed shaft passes through and slides between the inner walls of the through hole. The second connecting end is provided on the end of the fixed shaft and is rotatably connected to it.

[0018] The auxiliary components include slider one, slider two, and connecting bar. Slider one slides on the connecting rod, and an adjusting spring one is provided on the connecting rod between slider one and connecting end one. The connecting bar is fixed on slider one and the two are perpendicular to each other. Synchronizing rods are also connected between slider one on both sides. Slider two slides along the length of the connecting bar between the side walls of the connecting bar. A guide block is provided on slider two. The guide block always slides between the inner walls of the connecting bar. One end of the rotating shaft has a "T" shaped structure and is rotatably set between the inner walls of slider two.

[0019] In one embodiment, the second adjustment mechanism further includes a second screw, which is rotatably disposed between the inner walls of the first fixed groove and is arranged along the length of the first fixed groove. A rotary motor connected to and driving the second screw is installed on one side wall of the base. The second screw passes through the second adjustment seat and is engaged with it through a threaded transmission.

[0020] An electric telescopic rod is provided in the middle of the adjusting handle. The motor part of the electric telescopic rod is built into the inner wall of one side of the adjusting handle. The other end of the electric telescopic rod is connected to the adjusting handle on the other side. A connecting groove is provided on the bottom of the clamping seat one. One end of the adjusting handle is connected to the connecting groove through a shaft, and the other end of the adjusting handle is connected to the side wall of the adjusting seat two through a shaft connection.

[0021] In one embodiment, a side support is installed between one side wall of the fixing frame, and a transmission assembly is provided between the fixing frame and the base on the same side as the side support. The transmission assembly includes two driving components and two transmission components. Both the driving components and the transmission components are bevel gears, and the driving components and transmission components on the same side are meshed. A synchronous shaft 1 is rotatably disposed inside the side support. The two transmission components are respectively installed on both ends of the synchronous shaft 1. One driving component is connected and fixed to one end of the screw 1, while the other driving component is rotatably disposed on the side wall of the base. A synchronous shaft 2 is also provided between the driving component and the screw 2.

[0022] In one embodiment, when the second adjustment seat moves toward the side where the transmission component is located, the end of the positioning mechanism connected to the second adjustment mechanism moves upward, and at the same time, the first adjustment seat moves toward the side where the transmission component is located. The top of the pressing member moves synchronously with the first adjustment seat, and its lower end moves downward in the vertical direction. At this time, the counterweight rollers are piled up on the lower end of the solar panel under the action of the auxiliary component and the pressing member.

[0023] When the second adjusting seat moves away from the transmission component, the end of the positioning mechanism connected to the second adjusting mechanism moves downward, and at the same time, the first adjusting seat moves away from the transmission component. The top of the pressing member moves synchronously with the first adjusting seat, and its lower end moves upward in the vertical direction. At this time, the counterweight rollers are distributed on the solar panel under the action of the auxiliary component and the pressing member.

[0024] A detection method based on a solar cell detection system includes the following steps:

[0025] S1. First, the solar panel to be tested is fixedly clamped on the positioning mechanism. At the same time, the length of the adjustment handle is adjusted appropriately according to the size of the solar panel. After the solar panel is fixed, several counterweight rollers are placed on its surface. The test requirements of different pressures can be adjusted by changing the number of counterweight rollers. The solar panel and the control panel are connected through a signal line to monitor various performances in real time.

[0026] S2. Next, start the rotary motor to drive screw one and screw two synchronously, so that adjustment seat one and adjustment seat two start to move synchronously and in the same direction, thereby controlling the angle adjustment of the solar panel. In addition, during the adjustment of different angles, the distribution of the counterweight roller is completed synchronously to more realistically reproduce the force distribution of the real situation.

[0027] S3. Then, the performance indices of the solar panel under different test angles reflect its compressive strength. After the test is completed, the solar panel can be removed.

[0028] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0029] By incorporating adjustment mechanisms one and two, a positioning mechanism, and a transmission assembly, the positioning mechanism clamps and fixes the solar panel under test, and is compatible with various specifications of solar panels. The transmission assembly then synchronizes the movement of adjustment mechanisms one and two, allowing for simultaneous adjustment of the counterweight roller distribution on the solar panel as its angle is adjusted. This better simulates the stress distribution of the solar panel in a real-world environment. Finally, the changes in various performance data of the solar panel under different test conditions reflect its compressive strength. This invention effectively simulates the stress on solar panels in sandy environments to test their compressive strength under harsh conditions. Attached Figure Description

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0041] like Figure 1-2 As shown, the present invention provides a technical solution: a solar cell-based detection system, including a base 1, a fixing frame 2, an adjustment mechanism 1 4, a positioning mechanism 5, an adjustment mechanism 2 7, and a counterweight roller 6. A control panel 11 with a PLC controller is screwed onto one side wall of the base 1. The four bottom ends of the fixing frame 2 are welded onto the base 1. A fixing groove 13 is formed along the length of the base 1, and the adjustment mechanism 2 7 is disposed within the fixing groove 13. Two symmetrical fixing grooves 2 14 are also formed on the base 1. The fixed slot 2 14 is set to facilitate the movement adjustment of the adjustment mechanism 1 4. A bearing seat 12 is installed on one side of the fixed slot 2 14 on both sides by welding. The positioning mechanism 5 is rotatably set between the bearing seats 12 on both sides. One end of the adjustment mechanism 2 7 is movably connected to one end of the positioning mechanism 5. The adjustment mechanism 2 7 is movably set above the positioning mechanism 5. The solar cell is clamped between the side walls of the positioning mechanism 5. Several counterweight rollers 6 (all counterweight rollers 6 have the same weight) are stacked between the surface of the solar cell and the adjustment mechanism 1 4.

[0042] It should be further explained that by fixing the solar panel to the positioning mechanism 5, the counterweight roller 6 is used to simulate the pressure of sand and dust accumulating on the solar panel. The pressure distribution of the counterweight roller 6 on the solar panel is controlled by the synchronous adjustment of the adjustment mechanism 2 7 and the adjustment mechanism 1 4, thereby simulating the different pressure distribution caused by the installation angle of the solar panel in reality, so as to test the pressure resistance of the solar panel.

[0043] like Figure 4 As shown, the positioning mechanism 5 includes a first clamp 51, a second clamp 52, a support platform 53, and a clamp block 54;

[0044] Both clamp 1 51 and clamp 2 52 are arranged in an "L" shape. A rotating shaft connected to the inner wall of clamp 2 52 runs through the end of clamp 2 52. The two ends of the rotating shaft rotate between the inner walls of the two side bearings 12. Support platforms 53 are installed on the opposite side walls of clamp 1 51 and clamp 2 52 by screws. Fixing groove 3 is also provided on the opposite side walls of clamp 1 51 and clamp 2 52. A horizontal shaft (not shown in the figure) is installed between the opposite inner walls of the two ends of fixing groove 3 by screws. Two opposing clamping blocks 54 slide on the horizontal shaft. A compression spring (not shown in the figure) is sleeved on one side of clamping block 54 on the horizontal shaft. One end of the compression spring is fixedly connected to the inner wall of fixing groove 3, and the other end is in contact with the side wall of clamping block 54 facing the inner wall of fixing groove 3.

[0045] Two connecting shafts 512 are welded to the side wall of clamp 1 51 facing clamp 2 52. The other end of the connecting shaft 512 always slides between the inner walls of clamp 2 52. Outer grooves are provided on both side walls of clamp 2 52. An adjusting gear 521 is rotatably mounted in the outer groove. A rotary motor (not shown in the figure) connected to and driven by the adjusting gear 521 is installed inside clamp 2 52 on one side. A connecting member 511 is provided on one side of the adjusting gear 521. The connecting member 511 is strip-shaped. The structure is configured such that one end of the connector 511 is connected and fixed to the clamp 51, and several toothed grooves that mesh with the adjusting gear 521 are evenly opened on the other end of the connector 511. A guide bar 5111 is also installed on the side wall of the connector 511 facing the connecting shaft 512 by screws. The longitudinal section of the guide bar 5111 is an isosceles trapezoid, and a guide groove matching the guide bar 5111 is also opened on the inner wall of one side of the outer groove. The end of the guide bar 5111 away from the clamp 51 never leaves the guide groove.

[0046] It should be further explained that the rotary motor is started by the PLC controller, which drives the adjusting gear 521 to rotate and output. The meshing transmission between the adjusting gear 521 and the connecting piece 511 controls the lateral distance between clamp 1 51 and clamp 2 52, so that the distance between them meets the length of the solar panel. Then, the clamps 54 on both sides are manually opened, and the solar panel is placed on the support platforms 53 on both sides. Then, the clamps 54 are released, and the clamps 54 are reset to the position in contact with the solar panel under the action of the compression spring. This makes the position of the solar panel fixed on the positioning mechanism 5. After the solar panel is fixed, the solar panel needs to be connected to the control panel 11 through the signal line so that the test results can be reflected by the changes in various real-time data.

[0047] like Figure 3 As shown, the adjustment mechanism 2 7 includes a screw 2 71, an adjustment seat 2 72, and an adjustment handle 73;

[0048] Two connecting slots are provided at the bottom end of the clamp 51;

[0049] Screw 2 71 is rotatably disposed between the inner walls of the fixing groove 13, and a rotary motor is bolted to one side wall of the base 1. The rotary motor is connected to and drives one end of screw 2 71. Adjusting seat 2 72 is slidably disposed between the inner walls of the fixing groove 13. Adjusting seat 2 72 is arranged in a "⊥" shape. Screw 2 71 passes through the middle position of adjusting seat 2 72 and is engaged with it through threaded transmission. Adjusting handle 73 is disposed on both side walls of adjusting seat 2 72 through shaft connection. The other end of adjusting handle 73 is disposed in the connecting groove on the same side through shaft connection.

[0050] The length of the adjusting handle 73 is adjustable and can be adjusted according to the distance between clamp 1 51 and clamp 2 52. An electric telescopic rod is provided in the middle of the adjusting handle 73. The motor part of the electric telescopic rod is built into the inner wall of one side of the adjusting handle 73, and the other end of the electric telescopic rod is connected to the adjusting handle 73 on the other side.

[0051] Furthermore, it is worth noting that when the adjusting seat 2 72 moves to Figure 3 When the leftmost position of the fixed groove 13 is shown, the right end of the adjusting handle 73 is still tilted upward.

[0052] It should be further explained that the rotary motor is started by the PLC controller, which drives the screw 71 to rotate. This, in turn, controls the adjusting seat 72 to move and adjust along the direction of the fixed groove 13 under the action of the threaded transmission. When the adjusting seat 72... Figure 3When the left side moves to the right, the adjusting handle 73 drives the left end of the positioning mechanism 5 to move upward, thereby increasing the angle between the solar panel and the horizontal plane (this angle refers to an acute angle, the same below). Meanwhile, when the adjusting seat 72 moves from its left side to the right... Figure 3 When the right side moves to the left, the adjusting handle 73 drives the left end of the positioning mechanism 5 to move downward, thereby reducing the angle between the solar panel and the horizontal plane. When the required test angle is reached, the adjustment can be stopped.

[0053] like Figure 5-7 As shown, the adjustment mechanism 4 includes an adjustment seat 41, a vertical plate 42, a pressing component 43, an auxiliary component 44, and a lifting seat 45;

[0054] Adjustment seat 41 slides between the two side walls of the fixed frame 2 along the length of the fixed frame 2. Two vertical plates 42 are provided and are respectively fixed to the two sides of the bottom wall of adjustment seat 41 by screws. The vertical plates 42 are set in a vertical state. Adjustment seat 41 has a "T" shaped structure. A pressing member 43 is provided on both side walls of adjustment seat 41. A lifting seat 45 is slidably provided on one of the two side walls of the fixed frame 2. The other end of the pressing member 43 is connected to the lifting seat 45.

[0055] Electric cylinders are installed on both sides of the base 1 by screws. The output shaft end of the electric cylinder is connected and fixed to the bottom wall of the lifting seat 45. A through hole is opened in the vertical direction on the fixed frame 2. The lifting seat 45 is arranged in a "U" shape. A fixed shaft is fixedly installed on one side wall of the lifting seat 45 by threaded connection. The fixed shaft passes through the through hole and slides in contact with the inner wall.

[0056] The pressing component 43 includes a connecting rod 431, a first connecting end 432, a second connecting end 433, and an adjusting spring 434;

[0057] The connecting rod 431 is fixed between the side walls of the first connecting end 432 and the second connecting end 433. The first connecting end 432 is connected between the side wall of the first adjusting seat 41 and the side wall of the vertical plate 42 via a shaft. The second connecting end 433 is rotatably mounted on one end of the fixed shaft. The first adjusting spring 434 is sleeved on the connecting rod 431, and one end of the first adjusting spring 434 is connected and fixed to the side wall of the first connecting end 432.

[0058] It should be further explained that when the adjusting seat 41 slides along the fixed frame 2, the adjusting seat 41 drives the connecting end 432 to move synchronously. At this time, the electric cylinder will be activated to control the lifting and lowering movement of the lifting seat 45, so that the connecting end 433 can move synchronously with the movement of the connecting end 432.

[0059] Auxiliary component 44 includes slider one 441, connecting bar 442, slider two 443, and rotating shaft 444;

[0060] Slider 441 slides on connecting rod 431, and a synchronizing rod is inserted and fixed between sliders 441 on both sides. The other end of adjusting spring 434 abuts against the side wall of slider 441. Connecting bar 442 is welded to slider 441 in a direction perpendicular to one side wall of slider 441. The bottom end of connecting bar 442 can move and adjust along the inner wall of fixing groove 14. Slider 443 is slidably arranged along the length of connecting bar 442. A guide block (not shown in the figure, the cross section of the guide block is an isosceles trapezoid) is welded on slider 443. The guide block always slides and adjusts along the inner wall of connecting bar 442. One end of rotating shaft 444 always rotates between the inner walls of slider 443 (this end of rotating shaft 444 is set in a "T" shape).

[0061] A through hole 2 is provided on the vertical plate 42 along its vertical direction. A top block 423 is slidably arranged between the inner walls of the through hole 2. A guide shaft 422 is welded to the top surface of the top block 423. The guide shaft 422 is arranged vertically, and the top end of the guide shaft 422 always slides between the inner walls of the vertical plate 42. An adjusting spring 2 is sleeved on the outside of the guide shaft 422. The top end of the adjusting spring 2 is fixed to the top wall of the through hole 2, and the bottom end of the adjusting spring 2 is fixed to the top surface of the top block 423. The lower surface of the top block 423 is an arc surface that matches the rotating shaft 444. The rotating shaft 444 slides between the inner walls of the through hole 2. The bottom end of the through hole 2 is also an arc surface that matches the rotating shaft 444, while the top end of the through hole 2 is a flat surface.

[0062] It should be further explained that by controlling the adjustment movement of the adjustment seat 41 and the lifting seat 45 through the PLC controller, the lower pressure parts 43 on both sides are adjusted in sync according to the state and their angle positions are adjusted appropriately. At the same time, in conjunction with the pressure applied by the auxiliary parts 44, the counterweight rollers 6 are concentrated in the area between the solar panel, the connecting rod 431 and the connecting strip 442.

[0063] like Figure 1-2 As shown, a transmission assembly 3 is also provided between the first adjustment mechanism 4 and the second adjustment mechanism 7. The transmission assembly 3 includes two driving members 31 and two transmission members 32, and both the driving members 31 and the transmission members 32 are bevel gears.

[0064] A side support 22 is bolted between the side walls of the fixed frame 2. A synchronous shaft 1 is rotatably connected to the middle of the side support 22. A convex ring (not shown in the figure) is provided on the synchronous shaft 1. The convex ring also rotates between the inner walls of the side support 22, so that the position of the synchronous shaft 1 on the side support 22 remains unchanged. Two transmission components 32 are respectively installed on both ends of the synchronous shaft 1 by key connection.

[0065] A screw 21, threadedly driven by the screw, runs through the inner wall of the adjusting seat 41. One end of the screw 21 is rotatably mounted on one side wall of the fixing frame 2 via a bearing, while the other end of the screw 21 runs through and rotates between the inner walls of the fixing frame 2 (the end that runs through is not threaded). A drive member 31 is mounted on this end of the screw 21 via a key connection. This drive member 31 is engaged with the transmission member 32 located above. The other drive member 31 is rotatably mounted on the side wall of the base 1 via a bearing and is engaged with the transmission member 32 located below. A synchronous shaft 2 (not shown in the figure) is also connected between the screw 71 and the drive member 31 located below.

[0066] It should be further explained that when screw 2 71 rotates under the action of the rotary motor, it drives the lower drive component 31 to rotate through the synchronous shaft 2. This, in turn, drives the upper drive component 31 to rotate in the same direction under the action of the transmission assembly 3, causing screw 1 21 to rotate synchronously. That is, screw 1 21 and screw 2 71 have the same output direction and speed. Specifically, when the adjusting seat 2 72 moves towards... Figure 2 As shown in the diagram, when the solar panel moves to the right, the angle between it and the horizontal plane increases (the angle refers to an acute angle), and simultaneously, the adjusting seat 41 also moves synchronously. Figure 2 As shown in the right-side movement, while the adjusting seat 41 moves, the electric cylinder starts and drives the lifting seat 45 to move. When the adjusting seat 41 moves to the right, the lifting seat 45 moves downward, and vice versa.

[0067] Adjusting seat 1 41 and adjusting seat 2 72 move synchronously. Figure 2 When the right side moves, the left end of the pressing part 43 moves to the right, while its right end moves down with the lifting seat 45. At the same time, under the action of adjusting spring 1 434 and adjusting spring 2, the connecting bar 442 moves with slider 1 441 and slider 2 443 towards the position closer to the clamp seat 51, so that these counterweight rollers 6... Figure 2 As shown, the solar panels are stacked at the bottom.

[0068] Conversely, when adjusting seat 1 41 and adjusting seat 2 72 move synchronously... Figure 2 When the left side moves, the left end of the pressing part 43 moves to the left, while its right end moves up with the lifting seat 45, causing the counterweight roller 6 to be pushed away from the clamp seat 51. However, under the action of the adjusting spring 434 and the adjusting spring 2, the connecting bar 442 is always in the state of moving towards the clamp seat 51. This allows the counterweight roller 6 to be restricted by the connecting bar 442 when it is pushed to one side, so that the counterweight roller 6 can be relatively dispersed on the solar panel and no longer concentrated at the end.

[0069] In addition, such as Figure 1As shown, in order to prevent the counterweight roller 6 from falling during the test, protective components are also set on both sides of the fixing frame 2. The protective components include a transparent baffle 23 and a plug 231.

[0070] The insertion rod 231 is fixedly inserted between the opposite side walls on both sides of the fixing frame 2. The baffle 23 is always set in a vertical direction and can slide and adjust along the length of the insertion rod 231. When the baffle 23 is adjusted to a suitable position, the top of the baffle 23 is fixed to the insertion rod 231 by fastening screws. The two ends of the counterweight roller 6 are respectively in contact with the baffles 23 on both sides.

[0071] Working principle:

[0072] First, the solar panel to be tested is fixedly clamped on the positioning mechanism 5. By controlling the rotation direction of the adjusting gear 521, the connecting piece 511 drives the clamp 1 51 to move and adjust, thereby adjusting the distance between the clamp 1 51 and the clamp 2 52. Then, the solar panel is fixed between the clamp 1 51 and the clamp 2 52, and the clamping blocks 54 on both sides are used to limit and fix the side of the solar panel. At the same time, the length of the adjusting handle 73 is adjusted appropriately according to the size of the solar panel. The total length of the adjusting handle 73 is adjusted appropriately by controlling the output distance of the electric telescopic rod. After the solar panel is fixed, several counterweight rollers 6 are placed on its surface. The test requirements of different pressures can be adjusted by changing the number of counterweight rollers 6. The solar panel and the control panel 11 are connected by a signal line to monitor various performances in real time.

[0073] Next, the rotary motor is started, causing screw 21 to start rotating and outputting. At the same time, under the action of transmission component 3, screw 21 also rotates synchronously, so that adjusting seat 41 and adjusting seat 22 start moving synchronously and in the same direction. The left and right displacement movement of adjusting seat 22 controls the angle adjustment of the solar panel. In addition, during the adjustment of different angles, the left and right displacement movement of adjusting seat 41, in conjunction with the vertical up and down movement of lifting seat 45, causes the pressing component 43 to continuously adjust its pressing state in real time according to the angle change of the solar panel. Meanwhile, the auxiliary component 44, under the action of adjusting spring 1 434 and adjusting spring 2, works with the pressing component 43 to limit the counterweight roller 6 during the adjustment of the pressing component 43, thereby completing the distribution of the counterweight roller 6 to more realistically reproduce the force distribution of the real situation.

[0074] Then, the solar panel's performance indices under different test angles reflect its compressive strength. After the test is completed, the solar panel can be removed.
