[0002] Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit electricity to the power grid. After the photovoltaic panel components of the photovoltaic power station are installed or used for a period of time, it is necessary to use an EL detector to detect internal defects, hidden cracks, fragments, cold solder joints, broken grids and abnormal phenomena of single-chip cells with different conversion efficiencies.

[0003] At present, EL detectors usually consist of a tripod and a high-resolution infrared camera shooting component.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a portable EL detector.

The support leg 12 is hingedly installed with multiple support legs 12 on the support sleeve 11. The multiple support legs 12 are used to support the support sleeve 11. In this embodiment, three support legs 12 are hingedly installed on the support sleeve 11, and the three support legs 12 are circumferentially spaced on the support sleeve 11; the support leg 12 includes an oblique support sleeve 121, an adjusting rod 122 and a tightening bolt 123. The oblique support sleeve 121 is hingedly installed on the outer wall of the support sleeve 11, and the adjusting rod 122 is slidably inserted on the inner wall of the oblique support sleeve 121. In this embodiment, the adjusting rod 122 is away from the oblique support sleeve 121. A rubber block 10 is hingedly installed at one end to increase the contact area between the adjusting rod 122 and the ground and improve the stability of the adjusting rod 122 against the ground; the tightening bolt 123 is threadedly installed on the inclined support sleeve 121, and the tightening bolt 123 extends into the inclined support sleeve 121 and abuts against the tightening bolt 123. In this embodiment, a rubber pad is installed at one end of the tightening bolt 123 that abuts against the adjusting rod 122. The rubber pad increases the friction between the tightening bolt 123 and the adjusting rod 122 while providing protection for the adjusting rod 122 to prevent the adjusting rod 122 from being scratched when the tightening bolt 123 is tightened against the adjusting rod 122.

[0035] The inspector rotates the three diagonal support sleeves 121 so that the three diagonal support sleeves 121 are away from the supporting sleeve 11, and then drives the adjusting rod 122 to slide on the inner wall of the supporting sleeve 11 in the direction away from or close to the diagonal support sleeve 121, and then rotates the tightening bolt 123 so that the tightening bolt 123 is tightened to the adjusting rod 122. At this time, under the tightening action of the tightening bolt 123, the adjusting rod 122 is pressed against the inner wall of the diagonal support sleeve 121, and the adjusting rod 122 can be positioned on the inner wall of the diagonal support sleeve 121 to complete the length adjustment of the supporting foot 12. At this time, the rubber blocks 10 on the three adjusting rods 122 are all in contact with the ground, and the erection of the frame 1 on the ground can be completed. Moreover, through the adjustment of the length of the supporting foot 12, the supporting foot 12 is suitable for different terrains, which effectively improves the applicability of the frame 1 to different terrains.

[0036] Reference Figure 1 , Figure 2A support assembly 5 is installed on the support sleeve 11. The support assembly 5 is used to support the diagonal support sleeve 121. The support assembly 5 includes a slide seat 51, an elastic sheet 52, a tapered sleeve 53 and a connecting rod 54. The slide seat 51 is slidably sleeved on the outer side wall of the support sleeve 11. A plurality of elastic sheets 52 are installed on the slide seat 51. The plurality of elastic sheets 52 are circumferentially spaced at intervals on the top of the slide seat 51. The elastic sheet 52 can be made of elastic materials such as stainless steel and plastic. In this embodiment, the elastic sheet 52 is made of stainless steel; the tapered sleeve 53 is threadedly sleeved on the outer side wall of the slide seat 51, and the tapered sleeve 53 is sleeved on the support sleeve 11. The inner opening of the tapered sleeve 53 It is arranged in a conical shape. In the present embodiment, the size of the internal opening of the conical sleeve 53 gradually increases from the direction away from the slide seat 51 to the direction close to the slide seat 51. In other embodiments, the internal opening of the conical sleeve 53 may also gradually decrease from the direction away from the slide seat 51 to the direction close to the slide seat 51. The inner side wall of the conical sleeve 53 abuts against a plurality of elastic sheets 52. A sliding sleeve 6 is slidably mounted on the diagonal support sleeve 121. A locking bolt 7 is threadedly mounted on the sliding sleeve 6. The locking bolt 7 passes through the sliding sleeve 6 and abuts against the diagonal support sleeve 121. Three connecting rods 54 are hingedly mounted on the slide seat 51. The three connecting rods 54 are respectively hinged on the sliding sleeves 6 on the three diagonal support sleeves 121.

[0037] The inspector drives the slide 51 to slide on the support sleeve 11. During the sliding process of the slide 51, the three connecting rods 54 can be moved away from the support sleeve 11. Then the inspector drives the conical sleeve 53 to rotate on the slide 51, so that the conical sleeve 53 moves toward the direction close to the slide 51. During the movement of the conical sleeve 53, the inner side wall of the conical sleeve 53 can squeeze the multiple elastic sheets 52, so that the multiple elastic sheets 52 are close to each other and clamped to the support sleeve 11, thereby positioning the slide 51 on the support sleeve 11, and then the inspector turns the lock. Tightening the bolt 7 makes the locking bolt 7 press against the diagonal support sleeve 121 and positions the sliding sleeve 6 on the diagonal support sleeve 121. At this time, the three connecting rods 54 can support the three diagonal support sleeves 121, improve the stability of the diagonal support sleeves 121, and further improve the stability of the frame 1 erected on the ground. The inspection personnel can loosen the locking bolt 7 to drive the sliding sleeve 6 to slide on the diagonal support sleeve 121, and the sliding sleeve 6 drives the connecting rod 54 to move, and adjusts the position of the connecting rod 54 supported on the diagonal support sleeve 121, thereby improving the applicability of the connecting rod 54 to different support needs.

[0038] Reference Figure 1The lifting rod 13 is threadedly installed on the inner wall of the support sleeve 11. The lifting rod 13 is rotatably installed with a turntable 8 in the horizontal direction, and a positioning assembly 9 is installed on the lifting rod 13. The positioning assembly 9 is used to position the turntable 8 on the lifting rod 13. The positioning assembly 9 includes a clamping plate 91 and a bidirectional screw 92. In this embodiment, a guide rod is installed on the lifting rod 13 in the vertical direction. Two clamping plates 91 are slidably installed on the guide rod.

The bidirectional screw 92 is threadedly connected to the two clamping plates 91, and the directions of the threads connecting the two clamping plates 91 are opposite.

[0039] The inspector rotates the bidirectional screw 92 to make the two clamps 91 approach each other, and the two clamps 91 can be respectively pressed against the two sides of the turntable 8 to position the turntable 8 on the lifting rod 13, which effectively improves the convenience of the inspector in positioning the turntable 8 on the frame 1. The inspector rotates the bidirectional screw 92 in the opposite direction to make the two clamps 91 move away from each other, thereby releasing the positioning of the turntable 8 on the lifting rod 13, so that the turntable 8 can rotate on the lifting rod 13.

[0040] Reference Figure 1 , Figure 3 , the mounting base 2 is hingedly mounted on the turntable 8 in the vertical direction, and the infrared camera 4 is detachably mounted on the mounting base 2. In the present embodiment, a threaded rod is mounted at the bottom of the infrared camera 4, and a threaded hole is provided on the mounting base 2, and the threaded rod is threadedly connected to the inner side wall of the threaded hole; one end of the telescopic rod 3 is hingedly mounted on the turntable 8, and the other end of the telescopic rod 3 is hingedly mounted on the mounting base 2, and the length of the telescopic rod 3 is retractable. In the present embodiment, the top of the turntable 8 is tilted, and the telescopic rod 3 is hingedly mounted on the inclined surface of the turntable 8, so that the detection personnel can adjust the inclination angle of the mounting base 2 in the vertical direction by adjusting the length of the telescopic rod 3. The telescopic rod 3 includes a connecting sleeve 31, a screw rod 32 and an adjusting sleeve 33. The connecting sleeve 31 is hingedly mounted on the inclined surface of the turntable 8, and the screw rod 32 is rotatably mounted on the connecting sleeve 31.

[0041] The inspector installs the infrared camera 4 on the mounting base 2. When the inclination angle of the infrared camera 4 needs to be adjusted, the inspector rotates the screw rod 32 to move the adjustment sleeve 33 toward or away from the screw rod 32. The adjustment sleeve 33 can drive the mounting base 2 to rotate in the vertical direction on the turntable 8. The mounting base 2 drives the infrared camera 4 to rotate, and the inclination angle of the infrared camera 4 can be adjusted without adjusting the frame 1, which effectively improves the convenience of the inspector to adjust the inclination angle of the infrared camera 4. When the inspector needs to adjust the horizontal angle of the infrared camera 4, he rotates the turntable 8, and the turntable 8 can drive the mounting base 2 and the infrared camera 4 rotate in the horizontal direction, and then the inspection personnel rotate the bidirectional screw 92, so that the two clamps 91 clamp the turntable 8, and position the turntable 8 on the lifting rod 13, so that the horizontal angle of the infrared camera 4 can be adjusted, which effectively improves the convenience of the inspection personnel to adjust the horizontal angle of the infrared camera 4; when the height of the infrared camera 4 needs to be adjusted, the inspection personnel rotates the lifting rod 13, so that the lifting rod 13 can be moved away from the support sleeve 11 or close to the support sleeve 11, and the lifting rod 13 can drive the infrared camera 4 to rise and fall in the vertical direction, which effectively improves the convenience of the inspection personnel to adjust the height of the infrared camera 4.

[0042] The implementation principle of a portable EL detector in an embodiment of the present application is as follows: the inspector sets up the frame 1 on the ground, then installs the infrared camera 4 on the mounting base 2, rotates the lifting rod 13 to adjust the height of the infrared camera 4, rotates the turntable 8, and then positions the turntable 8 through the clamping assembly to adjust the horizontal angle of the infrared camera 4, and adjusts the length of the telescopic rod 3 to make the mounting base 2 rotate up and down in the vertical direction to adjust the inclination angle of the infrared camera 4. The entire adjustment process does not require adjustment of the supporting feet 12, which effectively improves the convenience of the inspector in adjusting the inclination angle, height and horizontal angle of the infrared camera 4.
