Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1-4, a hidden crack detection device for a photovoltaic panel provided by the utility model: including a detection box 1, a hidden crack detection mechanism 2 is arranged on the top of the detection box 1, slots 3 are opened on both sides of the detection box 1, two detection frames 4 are arranged inside the detection box 1, connection grooves 11 are opened on the front and back inner walls of the detection box 1, the front and back of the detection frame 4 are respectively slidably connected inside the two connection grooves 11, clamping assemblies are arranged on both detection frames 4, an adjusting assembly, a cleaning assembly and a driving assembly are arranged on the detection box 1, lifting plates 5 are rotatably connected to the bottoms of the inner walls of the two detection frames 4, and the lifting ends of the lifting plates 5 are rounded to prevent the lifted lifting plates 5 from scratching the bottom of the photovoltaic panel. Two tapered grooves 6 are opened at the bottom of the inner wall of the detection frame 4, fixing plates 7 are fixedly connected to both sides of the detection box 1, two telescopic rods 8 are fixedly connected to the fixing plates 7, a first spring 9 is sleeved on the outer surfaces of the two telescopic rods 8, and tapered blocks 10 are fixedly connected to the tops of the two telescopic rods 8. By manually rotating the threaded rod 17 to make it rotate, under the limiting and guiding action of the two chutes 16, the two sliders 18 drive the two rubber clamping plates 14, the damper 13, the second spring 15 and the two rubber clamping plates 14 to move synchronously along the axial direction of the threaded rod 17, so as to simultaneously adjust the distance between the two rubber clamping plates 14, enabling it to clamp photovoltaic panels of different sizes, thereby improving the applicability of the device.

[0030] The clamping assembly includes two mounting plates 12, both of the two mounting plates 12 are arranged inside the detection frame 4, rubber clamping plates 14 are fixedly connected to the opposite sides of the two mounting plates 12 through a plurality of dampers 13, and a second spring 15 is sleeved on the outer surface of the damper 13.

[0031] The adjusting assembly includes two chutes 16 and a threaded rod 17. The two chutes 16 are respectively opened at the bottoms of the inner walls of the two detection frames 4. The threaded rod 17 is arranged on the two detection frames 4. Sliders 18 are slidably connected inside the two chutes 16. One end of the threaded rod 17 threadedly penetrates through the two sliders 18. The top of the slider 18 is fixedly connected to the bottom of one of the mounting plates 12, and the other mounting plate 12 is fixedly connected inside the detection frame 4.

[0032] The cleaning assembly includes an ion blower 19 fixedly installed on the front of the detection box 1. Blowing boxes 20 are fixedly connected to both sides of the detection box 1. The blowing ends of the ion blower 19 are respectively communicated with the two blowing boxes 20. Through the setting of the cleaning assembly, during the process of the photovoltaic panel moving into the detection box 1, ion wind can be blown to the photovoltaic panel to be detected, eliminating the static electricity on the photovoltaic panel and blowing away the adsorbed dust.

[0033] The driving assembly includes a cylinder 21 which is fixedly installed on the detection box 1, and the telescopic end of the cylinder 21 is fixedly connected to one end of one of the detection frames 4.

[0034] Working principle: During operation, first adjust the clamping assembly according to the size of the photovoltaic panel to be detected, that is, manually rotate the threaded rod 17 to make it rotate. Under the limiting and guiding action of the two sliding grooves 16, the two sliders 18 drive the two rubber clamping plates 14, several dampers 13, the second spring 15 and the two rubber clamping plates 14 to move synchronously along the axial direction of the threaded rod 17, and simultaneously adjust the distance between the two rubber clamping plates 14. Then, place the photovoltaic panel to be subjected to crack detection inside one of the detection frames 4 located outside the detection box 1, and simultaneously start the cylinder 21 and the ion blower 19. During the process of the telescopic end of the cylinder 21 contracting and driving the two detection frames 4 to move simultaneously to the other side of the detection box 1, the tapered block 10 extending into the tapered groove 6 can be extruded and moved out, so that the corresponding lifting plate 5 is reset, causing the placed photovoltaic panel not to tilt anymore. At the same time, when the cylinder 21 is started, one of the rubber clamping plates 14 inside the detection frame 4 where the photovoltaic panel is placed is pulled, so that the corresponding several dampers 13 and the second spring 15 are extruded. When slowly rebounding under the action of the elastic force of the second spring 15, the reset rubber clamping plate 14 fixedly clamps it inside the detection frame 4. After the ion blower 19 is started, it can blow ion wind to both sides of the detection box 1 through the two air blowing boxes 20, and can remove static electricity and dust from the photovoltaic panel during the moving process.

[0035] After the cleaned photovoltaic panel moves below the crack detection mechanism 2, the crack detection mechanism 2 can be started for detection. During the detection process, a photovoltaic panel to be detected can be placed inside the other detection frame 4 at the same time. When the photovoltaic panel is detected and removed from the detection box 1 for detecting another photovoltaic panel, one end of the detected photovoltaic panel can be lifted under the combined action of structures such as the telescopic rod 8, the first spring 9, the tapered block 10, the tapered groove 6 and the lifting plate 5, so as to facilitate the blanking of the detected photovoltaic panel.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
