Description

Technical Field

[0001] This utility model relates to the field of photovoltaic testing technology, and in particular to a photovoltaic power station testing device. Background Technology

[0002] With the vigorous development of the new energy industry, the scale of photovoltaic power plants is increasing day by day. As the core power generation unit, the operation status of photovoltaic panels is directly related to the power generation efficiency and stability of the power plant.

[0003] A search revealed a Chinese patent with publication number CN219893290U, which provides a photovoltaic power station testing device. This device, through the arrangement of a mounting frame, a moving plate, and a fixed plate, positions a first mounting box and a second mounting box above and below the photovoltaic module, respectively. By utilizing the cooperation of a motor, a lead screw, and a connecting block, the first and second mounting boxes are moved on the mounting frame. With the assistance of an electric push rod, a mounting plate, and a guide rod, a temperature measuring plate is used to perform bidirectional measurements on the outer surface of the photovoltaic module's illuminated and backlit sides.

[0004] However, during use, it was found that the device can only measure a single photovoltaic panel. In practical applications, photovoltaic power stations are usually composed of a large number of photovoltaic panels connected to each other in a matrix structure, which makes it difficult to meet the batch testing needs of multiple photovoltaic panels. It has problems such as inconvenience in operation, poor adaptability, low testing efficiency, and is not conducive to the testing of photovoltaic power stations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a photovoltaic power station inspection device. A CCD industrial camera acquires images of the photovoltaic panel surface, an ultrasonic flaw detection module detects internal structural defects, an infrared thermal imaging module identifies abnormal temperature points, and a silicone wheel is tightly attached to the photovoltaic panel surface to provide buffering and stable support, ensuring the stability of the device during the inspection process. The inspection dimensions are more comprehensive, improving the accuracy of defect identification and increasing inspection efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a photovoltaic power station testing device, including a photovoltaic panel, wherein multiple photovoltaic panels are provided, and the multiple photovoltaic panels are electrically connected to each other in a matrix structure. Each end of the photovoltaic panel is provided with a walking component, the walking component includes a walking frame, and a walking wheel is rotatably connected to the walking frame. The outer peripheral wall of the walking wheel abuts against the frame of the photovoltaic panel.

[0007] One of the walking frames is fixedly provided with a first fixed block, and a second fixed block is slidably connected inside the first fixed block. A guide rail is fixedly provided on the second fixed block, and support blocks are fixedly provided on the guide rail and the first fixed block, respectively. Stabilizing components are fixedly connected to the support blocks and the walking frame, and a T-shaped block is provided on the stabilizing component located on the support block. Multiple detection components are slidably connected on the T-block. The detection components include a moving block, and a CCD industrial camera, an ultrasonic flaw detection module, and an infrared thermal imaging module are respectively installed on the bottom surface of the moving block.

[0008] Preferably, the second fixing block is fixedly connected to another walking frame, the first fixing block has a limit groove, and the second fixing block and the guide rail are slidably connected to the limit groove.

[0009] Preferably, the guide rail is threaded to one end near the first fixing block with a first fastener, and one end of the first fastener abuts against the inner wall of the second fixing block.

[0010] By tightening the first fastener to press it against the inner wall of the second fixing block, the position of the detection component is locked, ensuring that the span remains unchanged during the detection process. This adapts to photovoltaic arrays with different installation spacings and facilitates the periodic inspection of photovoltaic arrays.

[0011] Preferably, a rotating shaft is rotatably connected to the walking frame, the walking wheels are sleeved on the outer peripheral wall of the rotating shaft, a servo motor is mounted on the top surface of the walking frame, and the output shaft of the servo motor is coaxially connected to the rotating shaft.

[0012] The above technical solution uses a servo motor to drive the rotating shaft and the walking wheels to rotate, enabling the device to move bidirectionally along the frame of the photovoltaic panel and cover multiple photovoltaic panel detection areas arranged in a matrix.

[0013] Preferably, the stabilizing component includes a stabilizing block, an adjusting block is slidably connected to the stabilizing block, a rotating rod is rotatably connected to the adjusting block, and multiple silicone wheels are sleeved on the rotating rod.

[0014] Preferably, the adjusting block has a through groove, and a spring is provided inside the through groove. One end of the spring is fixedly connected to the adjusting block, and the other end of the spring is fixedly connected to the stabilizing block.

[0015] Through the above technical solution, the spring is compressed or stretched, driving the adjusting block to slide along the stabilizing block, so that the silicone wheel always maintains contact with the surface of the photovoltaic panel, providing continuous and stable support force, reducing the shaking of the detection equipment caused by unstable support, and improving the clarity of the detection images and data.

[0016] Preferably, the T-shaped block is fixedly connected to the stabilizing block, and a second fastener is threaded onto the movable block, with one end of the second fastener abutting against the T-shaped block.

[0017] With the above technical solution, when the second fastener is loosened, the moving block can slide along the T-shaped block to adjust the detection position of the CCD industrial camera, ultrasonic flaw detection module, and infrared thermal imaging module.

[0018] Preferably, the height of the support block is not unique.

[0019] The above technical solution allows for the customization of the support block height based on the actual layout of the photovoltaic array, ensuring that the stable components remain parallel to the photovoltaic panels even in complex terrain, and guaranteeing that the distance between the detection components and the photovoltaic panel surface is appropriate for detection.

[0020] The beneficial effects of this utility model are:

[0021] A CCD industrial camera captures images of the photovoltaic panel surface, an ultrasonic flaw detection module detects internal structural defects, and an infrared thermal imaging module identifies abnormal temperature points. The three are combined to inspect the photovoltaic panel. Silicone wheels for stabilizing the components are in close contact with the photovoltaic panel surface, providing cushioning and stable support to ensure the stability of the device during the inspection process. The inspection dimensions are more comprehensive, improving the accuracy of defect identification and increasing inspection efficiency. Attached Figure Description

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-4 As shown, this embodiment provides a photovoltaic power station testing device, including a photovoltaic panel 100. Multiple photovoltaic panels 100 are provided and are electrically connected to each other in a matrix structure. A walking component 200 is provided at both ends of the photovoltaic panel 100. The walking component 200 includes a walking frame 201 and a walking wheel 202 rotatably connected to the walking frame 201. The outer peripheral wall of the walking wheel 202 abuts against the frame of the photovoltaic panel 100.

[0035] One of the walking frames 201 is fixed with a first fixing block 300. A second fixing block 400 is slidably connected inside the first fixing block 300. A guide rail 401 is fixed on the second fixing block 401. Support blocks 500 are fixed on the guide rail 401 and the first fixing block 300, respectively. Stabilizing components 600 are fixedly connected to the support blocks 500 and the walking frame 201, respectively. A T-shaped block 607 is provided on the stabilizing component 600 located on the support block 500. Multiple detection components 700 are slidably connected on the T-shaped block 607. The detection component 700 includes a moving block 701. A CCD industrial camera 702, an ultrasonic flaw detection module 703, and an infrared thermal imaging module 704 are respectively mounted on the bottom surface of the moving block 701.

[0036] The second fixing block 400 is fixedly connected to another walking frame 201. The first fixing block 300 has a limiting groove 301. The second fixing block 400 and the guide rail 401 are slidably connected to the limiting groove 301 respectively. The end of the guide rail 401 near the first fixing block 300 is threaded with a first fastener 402. One end of the first fastener 402 abuts against the inner wall of the second fixing block 400. Tightening the first fastener 402 makes it abut against the inner wall of the second fixing block 400, locking the position of the detection component 700, ensuring that the span remains unchanged during the detection process, adapting to photovoltaic panel 100 arrays with different installation spacing, and facilitating the periodic inspection of the photovoltaic array.

[0037] A rotating shaft 203 is rotatably connected to the walking frame 201, and a walking wheel 202 is sleeved on the outer peripheral wall of the rotating shaft 203. A servo motor 204 is installed on the top surface of the walking frame 201, and the output shaft of the servo motor 204 is coaxially connected to the rotating shaft 203. The forward and reverse rotation of the servo motor 204 drives the rotating shaft 203 to drive the walking wheel 202 to rotate, so as to realize the bidirectional movement of the device along the frame of the photovoltaic panel 100, covering the detection areas of multiple photovoltaic panels 100 arranged in a matrix.

[0038] The stabilizing component 600 includes a stabilizing block 601, an adjusting block 602 slidably connected to the stabilizing block 601, a rotating rod 605 rotatably connected to the adjusting block 602, and multiple silicone wheels 606 sleeved on the rotating rod 605. A through groove 603 is formed on the adjusting block 602, and a spring 604 is installed inside the through groove 603. One end of the spring 604 is fixedly connected to the adjusting block 602, and the other end of the spring 604 is fixedly connected to the stabilizing block 601. When the spring 604 is compressed or stretched, it drives the adjusting block 602 to slide along the stabilizing block 601, ensuring that the silicone wheels 606 always maintain contact with the surface of the photovoltaic panel 100, providing continuous and stable support, reducing the shaking of the detection equipment caused by unstable support, and improving the clarity of the detection images and data.

[0039] T-block 607 is fixedly connected to stabilizing block 601. A second fastener 705 is threaded onto movable block 701, and one end of the second fastener 705 abuts against T-block 607. When the second fastener 705 is loosened, movable block 701 can slide along T-block 607 to adjust the detection position of CCD industrial camera 702, ultrasonic flaw detection module 703, and infrared thermal imaging module 704.

[0040] The height of the support block 500 is not unique; the height of the support block 500 can be customized according to the actual layout of the photovoltaic panel 100 array, so that the stabilizing component 600 can still remain parallel to the photovoltaic panel 100 in complex terrain, and ensure that the distance between the detection component 700 and the surface of the photovoltaic panel 100 is appropriate for detection.

[0041] Working principle: The walking wheel 202 of the walking component 200 abuts against the frame of the photovoltaic panel 100. By rotating the walking wheel 202, the entire device moves along the frame of the photovoltaic panel 100, realizing position switching across the photovoltaic panel 100. The sliding connection between the first fixed block 300 and the second fixed block 400, in conjunction with the guide rail 401, allows the coverage of the detection component 700 to be adjusted according to the size of the photovoltaic panel 100, adapting to different specifications of photovoltaic panel 100 arrays and facilitating batch testing.

[0042] The moving block 701 of the detection component 700 slides along the T-shaped block 607, the CCD industrial camera 702 acquires images of the photovoltaic panel 100 surface, the ultrasonic flaw detection module 703 detects internal structural defects, and the infrared thermal imaging module 704 identifies abnormal temperature points. The three components work together to inspect the photovoltaic panel 100. The silicone wheel 606 of the stabilizing component 600 is in close contact with the surface of the photovoltaic panel 100, providing cushioning and stable support to ensure the stability of the device during the inspection process. The inspection dimensions are more comprehensive, improving the accuracy of defect identification and increasing the inspection efficiency.

[0043] After the outer peripheral wall of the walking wheel 202 abuts against the frame of the photovoltaic panel 100, the forward and reverse rotation of the servo motor 204 drives the rotating shaft 203 to rotate the walking wheel 202, realizing the bidirectional movement of the device along the frame of the photovoltaic panel 100, covering the detection areas of multiple photovoltaic panels 100 arranged in a matrix; by sliding the second fixed block 400 and the guide rail 401 along the first fixed block 300 through the limiting groove 301, the distance between the two walking frames 201 can be changed. After adjusting to the target span, the first fastener 402 is tightened to make it abut against the inner wall of the second fixed block 400, locking the position of the detection component 700, ensuring that the span remains unchanged during the detection process, adapting to photovoltaic panel 100 arrays with different installation spacing, and facilitating the periodic inspection of the photovoltaic array;

[0044] When moving, the stabilizing block 601 is elastically connected to the adjusting block 602 via the spring 604, and the silicone wheel 606 on the rotating rod 605 rolls in contact with the surface of the photovoltaic panel 100. When the device moves to an uneven area of ​​the photovoltaic panel 100, such as a splicing gap or slight warping, the spring 604 is compressed or stretched, driving the adjusting block 602 to slide along the stabilizing block 601, so that the silicone wheel 606 always maintains contact with the surface of the photovoltaic panel 100, providing continuous and stable support force, reducing the shaking of the detection equipment caused by unstable support, and improving the clarity of the detection images and data.

[0045] T-block 607 is fixedly connected to stabilizing block 601. Moving block 701 is locked to T-block 607 by second fastener 705. When the second fastener 705 is loosened, moving block 701 can slide along T-block 607 to adjust the detection position of CCD industrial camera 702, ultrasonic flaw detection module 703 and infrared thermal imaging module 704. After tightening, a rigid connection is formed to ensure the stability of the sensor position during the detection process and improve the detection efficiency of multi-specification photovoltaic panels 100.

[0046] The height of the support block 500 is not unique and can be customized according to the actual layout of the photovoltaic panel 100 array. This ensures that the stabilizing component 600 remains parallel to the photovoltaic panel 100 even in complex terrain, and ensures that the distance between the detection component 700 and the surface of the photovoltaic panel 100 is appropriate for detection, thus providing favorable conditions for the detection of photovoltaic power plants.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
