[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a detection tool for a photovoltaic power station, such as Figure 1-11 As shown, the inspection tooling for a photovoltaic power station includes: a workbench 1 and a support frame 2 arranged above the workbench 1; an EL inspection device 3 installed at the bottom of the inner wall of the support frame 2 for inspecting photovoltaic modules; a notch 4 opened on the workbench 1, the notch 4 being located directly below the EL inspection device 3; a conveyor 5 arranged in the notch 4 for conveying photovoltaic modules; a limit block 6 slidably arranged on the workbench 1 for limiting the position of photovoltaic modules; a storage mechanism arranged on the workbench 1 for storing the support frame 2; and a height adjustment mechanism arranged below the workbench 1 for adjusting the height of the conveyor 5.

[0035] In this embodiment, the photovoltaic module is first placed on the conveyor 5 so that one side of the photovoltaic module contacts the limit block 6, thereby limiting the photovoltaic module and ensuring that the center position of the photovoltaic module is directly opposite to the bottom of the EL detection device 3. Then, a power supply system that can provide stable current and voltage is used to ensure that the output voltage and current are within the rated range of the photovoltaic module so that the output can be adjusted according to the test requirements. A special test connection line and clamp are used to correctly connect the positive and negative poles of the photovoltaic module to the output end of the power supply system to ensure that the connection is firm and reliable to avoid looseness or short circuit during the test. The power supply system applies current and voltage to the photovoltaic solar panel to trigger the photovoltaic module cell to emit light. Then, the control system can be operated to control the EL detection device 3 so that the EL detection device 3 performs detection operations on the photovoltaic module. After the detection is completed, various defects on the panel can be observed in detail through the EL image processed and displayed by the computer. The zoom-in, zoom-out and drag functions provided by the software are used to carefully check each suspicious area and record the type, location and number of defects. After that, the control system controls the height adjustment mechanism to make the height adjustment mechanism drive the photovoltaic components to slide up, so that the photovoltaic components slide up to the top of the guide frame 36, and then start the conveyor 5, so that the conveyor 5 transports the photovoltaic components to the left side, so that they are placed on the guide frame 36, and the unloading operation is carried out through the roller on the guide frame 36. After that, the conveyor 5 can be returned to its position for subsequent continuity detection operations. When the detection is completed, the storage mechanism stores the support frame 2 for subsequent storage and sorting. Through the coordinated use of the conveyor 5 and the limit block 6, the photovoltaic components can be continuously and stably transported and limited on the detection table without frequent fixation and disassembly, thereby greatly improving the detection efficiency. Since the photovoltaic components can be continuously transported, the EL detection equipment 3 can perform continuous detection on them, avoiding detection interruptions caused by fixation and disassembly, and improving the accuracy and reliability of the detection. The design of the storage mechanism enables the support frame 2 to be conveniently stored after use, which not only saves space, but also is conducive to subsequent storage and management, and improves the convenience and practicality of tooling.

[0036] In a further preferred embodiment of the present invention, a U-shaped plate 7 is slidably provided on the workbench 1, a support frame 8 is rotatably installed on the U-shaped plate 7, a support plate 9 is slidably installed on the top of the support frame 8, and the support plate 9 is fixedly connected to the bottom of the support frame 2.

[0037] In this embodiment, a U-shaped plate 7 is slidably provided on the workbench 1, which provides a flexible supporting structure that can move along the workbench 1. A supporting frame 8 is rotatably installed on the U-shaped plate 7, which means that the supporting frame 8 can rotate on the U-shaped plate 7. Then, when the support frame 2 is stored, the support frame 2 can be rotated onto the workbench 1 for storage. By using the U-shaped plate 7, the supporting frame 8 and the supporting plate 9 in coordination, it is convenient to rotate the support frame 2 and place it on the workbench 1, thereby facilitating the storage of the support frame 2.

[0038] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a fixed plate 10 fixedly mounted on the bottom of the workbench 1; a bidirectional screw 11 rotatably mounted on the fixed plate 10; a group of connecting blocks 12 threadedly sleeved on the bidirectional screw 11; a group of connecting rods 13 hinged to a group of the connecting blocks 12 and the bottom of the conveyor 5 housing; a first sprocket 14 fixedly sleeved on the bidirectional screw 11, and a first chain 15 is sleeved on the first sprocket 14; a first motor 16 fixedly mounted on one side of the fixed plate 10, and the output shaft of the first motor 16 is fixedly connected to the bidirectional screw 11.

[0039] In this embodiment, when the height of the conveyor 5 needs to be adjusted, the first motor 16 is started, and the output shaft of the first motor 16 drives the bidirectional screw 11 to rotate. Since the two ends of the bidirectional screw 11 have opposite threads, when the bidirectional screw 11 rotates, a set of connecting blocks 12 moves in a relative or opposite direction along the thread direction of the screw 11. The movement of the connecting blocks 12 drives the outer shell of the conveyor 5 to move up and down through the hinged connecting rod 13, thereby realizing the height adjustment of the conveyor 5. After the height adjustment is completed, the first motor 16 is turned off. At this time, the bidirectional screw 11 stops rotating, and the height of the conveyor 5 remains stable. Then, the conveyor 5 unloads the photovoltaic modules. Then, the first motor 16 is started again to return the conveyor 5 to its original position, and then a new photovoltaic module is placed on the conveyor 5, which is limited by the limit block 6 and then detected by the EL detection device 3. The bidirectional screw 11 is driven to rotate by the first motor 16, thereby realizing automatic adjustment of the height of the conveyor 5, simplifying the operation process and improving the adjustment efficiency. Due to the thread design of the bidirectional screw 11, the height of the conveyor 5 can be accurately adjusted to ensure the optimal alignment relationship between the EL detection device 3 and the photovoltaic module. The connecting block 12 and the bottom of the conveyor 5 casing are connected by the hinged connecting rod 13, so that the conveyor 5 can remain stable during the height adjustment process to avoid shaking or tilting.

[0040] In a further preferred embodiment of the present invention, a rectangular rod 17 is fixedly installed on one side of the support frame 8, a U-shaped block 18 is slidably installed on the rectangular rod 17, the U-shaped block 18 is slidably connected to the slot of the U-shaped plate 7, a fixing bolt 19 is threadedly installed on the U-shaped block 18, and the fixing bolt 19 is in rotational contact with the rectangular rod 17.

[0041] In this embodiment, when it is necessary to adjust the angle or position of the support frame 8, first loosen the fixing bolts 19 to release the fixation of the U-shaped block 18 on the rectangular rod 17, then slide the U-shaped block 18 along the length direction of the rectangular rod 17 to make the U-shaped block 18 slide away from the slot of the support frame 8, and then the support frame 8 can be rotated. The setting of the U-shaped block 18 and the fixing bolts 19 makes it easy to quickly fix the support frame 8, thereby ensuring the stability of the EL detection device 3 during use.

[0042] In a further preferred embodiment of the present invention, the storage mechanism includes: a first rack 20 fixedly mounted on one side of the support frame 2; a plurality of connecting gears 21 rotatably mounted on the support frame 8 and the U-shaped plate 7, respectively, and the connecting gear 21 located above is meshed with the first rack 20; a mounting plate 22 fixedly mounted on one side of the U-shaped plate 7; a plurality of second sprockets 23 respectively arranged on the mounting plate 22 and the plurality of connecting gears 21, and two second chains 24 are sleeved on the plurality of second sprockets 23, and the two second chains 24 are respectively meshed with the plurality of second sprockets 23; a rotating rod 25 rotatably mounted on the mounting plate 22; a second motor 26 fixedly mounted on the other side of the mounting plate 22, and a bevel gear 27 is fixedly sleeved on the output shaft of the second motor 26 and the rotating rod 25, and the two bevel gears 27 are meshed with each other.

[0043] In this embodiment, when the support frame 2 needs to be stored, the second motor 26 is first started, and the output shaft of the second motor 26 will drive the bevel gear 27 thereon to rotate. Since the two bevel gears 27 are meshed, the rotating rod 25 will also rotate with the rotation of the bevel gear 27. The rotation of the rotating rod 25 will drive the second sprocket 23 connected thereto to rotate, and then through the transmission action of the second chain 24, the other second sprockets 23 and the connecting gear 21 are driven to rotate synchronously. The connecting gear 21 located at the top is meshed with the first rack 20. Therefore, when the connecting gear 21 rotates, it will drive the first rack 20 and the support frame 2 to move up and down, so that the support frame 2 drives the support plate 9 to slide along the support frame 8, thereby adjusting the height of the support frame 2 and realizing the storage or expansion of the support frame 2. Open, after the storage is completed, turn off the second motor 26, at this time, each component will maintain the current position unchanged, ensuring the stability and reliability of the storage mechanism, and then rotate the support frame 8 to make the support frame 2 rotate and contact the workbench 1, and perform the storage operation on the support frame 2. The second motor 26 drives the transmission action of the bevel gear 27 and the second sprocket to realize the automatic storage and deployment of the support frame 2, simplify the operation process, and improve work efficiency. The design of the storage mechanism allows the support frame 2 to be conveniently stored when not in use, which not only saves space, but also makes the structure of the entire inspection tooling more compact and tidy. Through the synchronous rotation of multiple connecting gears 21 and the second sprocket 23, the stability and smoothness of the support frame 2 during the storage and deployment process can be ensured, avoiding shaking or jamming.

[0044] In a further preferred embodiment of the present invention, a second rack 28 is fixedly installed on one side of the workbench 1, and the second rack 28 is meshed with the connecting gear 21 located on the U-shaped plate 7. A limit seat is fixedly installed on one side of the support frame 8, and the limit seat is slidably connected to the sliding mouth of the first rack 20.

[0045] In this embodiment, when the position of the U-shaped plate 7 and the support frame 2 needs to be adjusted, the second motor 26 will be started to drive the rotating rod 25 and the bevel gear 27 to rotate. The rotation of the bevel gear 27 will drive the second sprocket 23 and the second chain 24 to transmit, and then drive the connecting gear 21 to rotate. Since the two connecting gears 21 are respectively meshed with the first rack 20 and the second rack 28, it will be subject to driving forces in two directions. The driving forces in these two directions will act on the U-shaped plate 7 and the support frame 2 together, so that they can move smoothly along a predetermined path. Then, when the support frame 2 slides down, the U-shaped plate 7 slides to the left, and at the same time, the limit seat on one side of the support frame 8 will be on the first rack 20 The U-shaped plate 7 and the support frame 2 slide in the sliding mouth to further limit the movement range of the support frame 2 to ensure its stability and safety. When the U-shaped plate 7 and the support frame 2 move to the desired position, the second motor 26 is turned off. At this time, each component will maintain the current position unchanged, so as to facilitate the storage operation of the support frame 2. The second rack 28 and the limit seat design can further enhance the stability of the U-shaped plate 7 and the support frame 2 during the movement to prevent them from shaking or deviating from the predetermined track. Since the connecting gear 21 is constrained by the first rack 20 and the second rack 28 at the same time, the position of the U-shaped plate 7 and the support frame 2 can be accurately adjusted to ensure the optimal alignment relationship between the EL detection equipment and the photovoltaic component.

[0046] In a further preferred embodiment of the present invention, a protective cover 30 is installed at the bottom of the workbench 1. The protective cover 30 is U-shaped and consists of a bottom plate and two baffles. The two baffles are respectively located on one side of the workbench 1.
