Description

Technical Field

[0001] The present invention relates to the technical field of solar cells, and in particular to a detection system based on solar cells and a detection method thereof. Background Art

[0002] Solar cells are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. They are also called "solar chips" or "photovoltaic cells". As long as they are illuminated by light that meets certain illumination conditions, they can instantly output voltage and generate current in the presence of a circuit. Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect.

[0003] Generally, large-scale installation of solar cells is carried out outdoors in open areas. Different environments will cause different problems to be solved during the operation of solar cells, especially in sandy environments (such as deserts). Since solar cells are installed at an angle, sand will preferentially gather at the bottom of the solar cells when attached to them. For solar cells installed at different angles, the pressure distribution of sand on the solar cells is also different.

[0004] A Chinese patent with announcement number CN218036158U discloses a compressive quality testing device for outdoor photovoltaic power generation components. The testing device mainly applies pressure to the solar panel by applying fluid in a pressure bag to simulate the pressure testing process of the photovoltaic power generation component. However, the installation angles of all solar panels cannot be the same. Due to the differences in sunshine duration in different places, solar panels in different regions need to be adjusted at 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.

DETAILED DESCRIPTION

[0040] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate 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 detection system based on solar cells, 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 installed on one side wall of the base 1 by screws, the four bottom ends of the fixing frame 2 are installed on the base 1 by welding, a fixing groove 13 is opened on the base 1 along its length direction, the adjustment mechanism 2 7 is arranged in the fixing groove 13, and the base 1 is also opened with two symmetrical fixing grooves 2 14, the fixing The setting of the fixed groove 14 is to facilitate the movement adjustment of the adjustment mechanism 4. The shaft seat 12 is installed on one side of the fixed groove 14 on both sides by welding. The positioning mechanism 5 is rotatably set between the shaft seats 12 on both sides, and one end of the adjustment mechanism 7 is movably connected to one end of the positioning mechanism 5. The adjustment mechanism 7 is movably set above the positioning mechanism 5. The solar cell is clamped between the side walls of the positioning mechanism 5, and a number of counterweight rollers 6 are stacked between the surface of the solar cell and the adjustment mechanism 4 (the weight of the counterweight rollers 6 are all the same).

[0042] It should be further explained that, by fixing the solar panel on the positioning mechanism 5, and then using the counterweight roller 6 to simulate the pressure of sand and dust accumulated on the solar panel, and through the synchronous adjustment and coordination of the adjustment mechanism 2 7 and the adjustment mechanism 1 4, the pressure distribution of the counterweight roller 6 on the solar panel is controlled, thereby simulating the different pressure distribution caused by the installation angle of the solar panel in practice, so as to detect the compressive resistance of the solar panel.

[0043] like Figure 4 As shown, the positioning mechanism 5 includes a clamping seat 1 51, a clamping seat 2 52, a support platform 53 and a clamping block 54;

[0044] The clamp seat 1 51 and the clamp seat 2 52 are both arranged in an "L"-shaped structure, and a rotating shaft connected to the clamp seat 2 52 is passed through the inner walls of the ends thereof, and the two ends of the rotating shaft rotate respectively between the inner walls of the shaft seat 12 on both sides, and support platforms 53 are installed on the opposite side walls of the clamp seat 1 51 and the clamp seat 2 52 by screws, and a fixing groove 3 is also opened on the opposite side walls of the clamp seat 1 51 and the clamp seat 2 52, and a horizontal axis (not shown in the figure) is installed between the opposite inner walls at both ends of the fixing groove 3 by screws, and two oppositely arranged clamping blocks 54 are slidably arranged on the horizontal axis, and a compression spring (not shown in the figure) is sleeved on one side of the clamping block 54 on the horizontal axis, and one end of the compression spring is fixedly connected to the inner wall of the fixing groove 3, and the other end is in contact with the side wall of the clamping block 54 facing the inner wall of the fixing groove 3.

[0045] Two connecting shafts 512 are welded on the side wall of the clamp seat 1 51 facing the clamp seat 2 52, and the other end of the connecting shaft 512 always slides between the inner walls of the clamp seat 2 52. The side walls of the clamp seat 2 52 are provided with outer grooves on both sides, and an adjusting gear 521 is rotatably arranged in the outer groove. A rotating motor (not shown in the figure) connected to and driven by the adjusting gear 521 is installed on one side of the adjusting gear 521 in the clamp seat 2 52. A connecting piece 511 is provided on one side of the adjusting gear 521. The connecting piece 511 is in a strip shape. A structure is provided, and one end of the connecting member 511 is connected and fixed to the clamp seat 51, and a plurality of tooth grooves meshing with the adjusting gear 521 are evenly provided on the other end thereof, and a guide bar 5111 is also installed on the side wall of the connecting member 511 facing the connecting shaft 512 by screws, and the longitudinal section of the guide bar 5111 is an isosceles trapezoid, and a guide groove matching the guide bar 5111 is also provided on the inner wall on one side of the outer groove, and the end of the guide bar 5111 away from the clamp seat 51 never leaves the guide groove.

[0046] It should be further explained that the rotary motor is started by the PLC controller to drive the adjusting gear 521 to rotate and output, so that the meshing transmission between the adjusting gear 521 and the connecting member 511 is used to control the lateral distance between the clamp seat 1 51 and the clamp seat 2 52, so that the distance between the two meets the length of the solar panel, and then the clamp blocks 54 on both sides are manually opened, and the solar panel is lowered to be placed on the support platforms 53 on both sides, and then the clamp blocks 54 are released, so that the clamp blocks 54 are reset to the position in contact with the solar panel under the action of the compression spring and stop, so that the position of the solar panel is positioned on the positioning mechanism 5. After the solar panel is fixed, it is necessary to connect the solar panel and the control panel 11 through a signal line so that the test results can be reflected through various real-time data changes.

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

[0048] Two connecting grooves are provided at the bottom end of the clamping seat 51;

[0049] The second screw rod 71 is rotatably arranged between the inner walls of the fixing groove 13, and a rotating motor is installed on one side wall of the base 1 by bolts. The rotating motor is connected to one end of the second screw rod 71 and drives it. An adjusting seat 72 is slidably arranged between the inner walls of the fixing groove 13. The adjusting seat 72 is arranged in a "⊥" shape. The second screw rod 71 passes through the middle position of the adjusting seat 72 and cooperates with it through threaded transmission. Adjusting handles 73 are arranged on both side walls of the adjusting seat 72 through shaft connections. The other end of the adjusting handle 73 is arranged in a connecting groove on the same side as it through shaft connection.

[0050] Among them, the length of the adjustment handle 73 is adjustable, and its length can be adjusted according to the distance between the clamp seat 1 51 and the clamp seat 2 52. An electric telescopic rod is arranged in the middle of the adjustment handle 73. The motor part of the electric telescopic rod is built between the inner walls of the adjustment handle 73 on one side, and the other end of the electric telescopic rod is connected to the adjustment handle 73 on the other side.

[0051] In addition, it is worth noting that when the adjustment seat 2 72 moves to Figure 3 When the fixing slot 13 is at the leftmost position, the right end of the adjusting handle 73 is still in a tilted upward state.

[0052] It should be further explained that the rotating motor is started by the PLC controller to drive the screw rod 71 to rotate, thereby controlling the adjustment seat 72 to move and adjust along the direction of the fixed groove 13 under the action of the screw transmission. Figure 3When the left side of the adjusting seat 72 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). Figure 3 When the right side of the positioning mechanism 5 moves to the left, the adjusting handle 73 drives the left end of the positioning mechanism 5 to move downward, thereby lowering the angle between the solar cell panel and the horizontal plane. When the angle is adjusted to the desired test angle, the test mechanism 5 can stop.

[0053] like Figure 5-7 As shown, the adjustment mechanism 1 4 includes an adjustment seat 1 41, a vertical plate 42, a pressing member 43, an auxiliary member 44 and a lifting seat 45;

[0054] The adjusting seat 41 slides between the side walls of the fixing frame 2 along the length direction of the fixing frame 2. Two vertical plates 42 are provided and are respectively fixed on the two sides of the bottom wall of the adjusting seat 41 by screws. The vertical plates 42 are arranged in a vertical state. The adjusting seat 41 is a "T"-shaped structure. Down-pressing pieces 43 are arranged on the side walls of the adjusting seat 41. A lifting seat 45 is slidably arranged on the side walls of the fixing frame 2 on both sides. The other end of the down-pressing piece 43 is connected to the lifting seat 45.

[0055] Electric cylinders are installed on both side walls of the base 1 by screws, and the output shaft end of the electric cylinder is connected and fixed to the bottom wall of the lifting seat 45. A through hole 1 is opened in the vertical direction on the fixing frame 2. The lifting seat 45 is arranged in a "U"-shaped structure, and 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 member 43 includes a connecting rod 431, a connecting end 1 432, a connecting end 2 433 and an adjusting spring 1 434;

[0057] The connecting rod 431 is fixed between the side walls of the connecting end 1 432 and the connecting end 2 433. The connecting end 1 432 is connected between the side wall of the adjusting seat 1 41 and the side wall of the vertical plate 42 through an axis. The connecting end 2 433 is rotatably set on one end of the fixed axis. The adjusting spring 1 434 is sleeved on the connecting rod 431, and one end of the adjusting spring 1 434 is connected and fixed to the side wall of the connecting end 1 432.

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

[0059] The auxiliary member 44 includes a slider 1 441 , a connecting bar 442 , a slider 2 443 and a rotating shaft 444 ;

[0060] Slider 1 441 slides on connecting rod 431, and a synchronization rod is inserted and fixed between sliders 1 441 on both sides, the other end of adjusting spring 1 434 is in contact with the side wall of slider 1 441, connecting strip 442 is welded to slider 1 441 in a direction perpendicular to one side wall of slider 1 441, the bottom end of connecting strip 442 can be moved and adjusted along the inner wall of fixing groove 2 14, and slider 2 443 is slidably arranged along the length direction of connecting strip 442, a guide block (not shown in the figure, the cross-section of the guide block is an isosceles trapezoid) is welded to slider 2 443, the guide block always slides and adjusts along the inner wall of connecting strip 442, and one end of rotating shaft 444 always rotates between the inner walls of slider 2 443 (this end of rotating shaft 444 is arranged in a "T"-shaped structure).

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

[0062] It should be further explained that the adjustment movement of the adjustment seat 41 and the lifting seat 45 is controlled by the PLC controller, so that the downward pressing parts 43 on both sides can synchronously adjust their angular positions according to the status. At the same time, with the pressure of the auxiliary parts 44, the counterweight rollers 6 are concentrated in the area between the solar cell panel, the connecting rod 431 and the connecting strip 442.

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

[0064] A side support 22 is installed between the side walls of the fixing frame 2 by bolts, and a synchronous shaft 1 is passed through the middle of the side support 22 to rotate with it. A convex ring (not shown in the figure) is provided on the synchronous shaft 1, and 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 members 32 are respectively installed on the two ends of the synchronous shaft 1 in a key connection manner.

[0065] A screw rod 21 threadedly driven therewith is penetrated in the middle of the inner wall of the adjustment seat 41, one end of the screw rod 21 is rotatably set on one side wall of the fixing frame 2 through a bearing, and the other end of the screw rod 21 penetrates and rotates between the inner walls of the fixing frame 2 (the penetrated end is not threaded), and a driving member 31 is installed on this end of the screw rod 21 through a key connection, and the driving member 31 is meshed with the transmission member 32 located above. The driving member 31 on the other side is rotatably set on the side wall of the base 1 through a bearing and meshed with the transmission member 32 located below, and a synchronous shaft 2 (not shown in the figure) is also connected between the screw rod 71 and the driving member 31 located below.

[0066] It should be further explained that when the screw rod 2 71 rotates under the action of the rotary motor, the synchronous shaft 2 will drive the driving member 31 located below to rotate, so that under the action of the transmission assembly 3, the driving member 31 above is synchronously driven to rotate in the same direction, so that the screw rod 1 21 rotates synchronously therewith, that is, the output directions of the screw rod 1 21 and the screw rod 2 71 are the same, and the output speeds are also the same, that is, when the adjusting seat 2 72 is turned to Figure 2 When the solar panel moves to the right side as shown in the figure, the angle between the solar panel and the horizontal plane becomes larger (the angle refers to an acute angle), and the adjustment seat 41 also moves synchronously. Figure 2 As shown in the right side movement, when 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] The adjusting seat 1 41 and the adjusting seat 2 72 are synchronously moved to Figure 2 When the right side moves, the left end of the pressing member 43 moves rightward, and the right end thereof moves downward with the lifting seat 45. At the same time, under the action of the adjusting spring 1 434 and the adjusting spring 2, the connecting bar 442 moves with the slider 1 441 and the slider 2 443 toward the side where the clamping seat 1 51 is located, so that the counterweight rollers 6 are as follows. Figure 2 The stack is shown at the bottom end of the solar panel;

[0068] On the contrary, when the adjusting seat 1 41 and the adjusting seat 2 72 are synchronously moved Figure 2 When the left side moves, the left end of the pressing piece 43 moves to the left, and the right end moves up with the lifting seat 45, so that the counterweight roller 6 is pushed away from the side where the clamp seat 51 is located. However, under the action of the adjusting spring 1 434 and the adjusting spring 2, the connecting strip 442 is always in a state of moving toward the side where the clamp seat 51 is located, so that the counterweight roller 6 can be restricted by the connecting strip 442 when it is pushed to one side, so that these counterweight rollers 6 can be relatively dispersed on the solar cell panel and no longer concentrated at the end.

[0069] In addition, if Figure 1As shown, in order to prevent the counterweight roller 6 from falling during the test, protective components are respectively provided on both sides of the fixed frame 2, and the protective components include a transparent baffle 23 and an insertion rod 231;

[0070] The insertion rod 231 is fixedly inserted between the opposite side walls of the fixing frame 2, the baffle 23 is always set in the vertical direction, and the baffle 23 can be slidably adjusted along the length direction 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 tightening screws, and the two ends of the counterweight roller 6 are respectively contacted 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, and the rotation direction of the adjusting gear 521 is controlled so that the connecting piece 511 drives the clamp seat 1 51 to move and adjust, so as to adjust the distance between the clamp seat 1 51 and the clamp seat 2 52, and then the solar panel is clamped between the clamp seat 1 51 and the clamp seat 2 52, and the clamp blocks 54 on both sides are used to assist in limiting and fixing the side of the solar panel. At the same time, the length of the adjusting handle 73 is appropriately adjusted according to the size of the solar panel, and the total length of the adjusting handle 73 is appropriately adjusted by controlling the output distance of the electric telescopic rod, and after the solar panel is fixed, a number of 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 placed, and the solar panel and the control panel 11 are connected through signal lines to monitor various performances in real time;

[0073] Next, the rotary motor is started to make the screw rod 2 71 start to rotate and output. At the same time, under the action of the transmission component 3, the screw rod 1 21 also rotates synchronously, so that the adjustment seat 1 41 and the adjustment seat 2 72 start to move synchronously and in the same direction. The angle adjustment of the solar panel is controlled by the left and right displacement movement of the adjustment seat 2 72. In addition, during the adjustment of different angles, the left and right displacement movement of the adjustment seat 1 41 and the vertical up and down movement of the lifting seat 45 are coordinated, so that the pressing member 43 continuously adjusts its pressing state in real time according to the angle change of the solar panel. During the adjustment process of the pressing member 43, the auxiliary member 44 cooperates with the pressing member 43 under the action of the adjusting spring 1 434 and the adjusting spring 2 to limit the counterweight roller 6, thereby completing the distribution of the counterweight roller 6, so as to more realistically restore the force distribution of the actual situation.

[0074] Then, the various performance indexes of the solar panel at different test angles reflect its compressive resistance. After the test is completed, the solar panel can be removed.
