When using the portable EL detector to detect the laid solar panels, first take out the fixing plate from the portable box. 11 is taken out, four support frames 12 are respectively fixed at the four corners of the bottom end of the fixing plate 11, and a hammer is used to hammer the fixing plate 11 for multiple times, and the cone rods 13 fixed to the bottom ends of the multiple support frames 12 are respectively nailed into the bumpy and complex ground, so that the upper end surface of the fixing plate 11 remains horizontal, and the connecting mechanism is installed on the outer walls of the multiple support frames 12 under the fixing plate 11, and the EL detector 1 is fixed to the bottom plate. The EL detector 1 is connected to the fixing plate 11 through the connecting mechanism to achieve the function of stable assembly of the portable EL detector. The EL detector 1 is aimed at the laid solar panel for detection, which is suitable for use on bumpy and complex ground, reducing the occurrence of damage to the portable EL detector when it is used. At the same time, the portable EL detector can be disassembled after use and placed in a portable box for carrying.

[0030] like Figures 1 to 3 , Figure 5As shown, the connecting mechanism also includes a sliding plate 2, a connecting block 21, a connecting plate 22, a square tube 23, a plug rod 24, a No. 1 nut 25 and a lifting assembly; the sliding plate 2 is slidably connected to the outer wall of a plurality of support frames 12; a positioning assembly is arranged inside the sliding plate 2, and the positioning assembly is used to limit the sliding plate 2 after sliding; the connecting block 21 is fixedly connected to the middle inner wall of the sliding plate 2; the connecting plate 22 is arranged on the middle inner wall of the connecting block 21; the square tube 23 is fixedly connected to the end of the connecting plate 22; the plug rod 24 is plugged into the inside of the connecting block 21, and the plug rod 24 passes through the connecting plate 22; the No. 1 nut 25 is threadedly connected to the plug rod 24; the lifting assembly is arranged on the inner wall of the square tube 23, and the lifting assembly is used to Control the lifting height of the EL detector 1; when assembling the portable EL detector, slide the sliding plate 2 on the outer wall of the four support frames 12, and assist the assembly of the sliding plate 2 through the positioning assembly, which is not shown in the figure. The positioning assembly is used to release the limit when the sliding plate 2 slides on the outer wall of the four support frames 12, and to limit the sliding plate 2 when the sliding plate 2 stops sliding on the four support frames 12. The connecting plate 22 at the bottom end of the square tube 23 is inserted into the middle of the connecting block 21, and the connecting block 21 and the connecting plate 22 are penetrated by the plug-in rod 24, and the plug-in rod 24 is threadedly connected with a No. 1 nut 25. The square tube 23 cooperates with the lifting assembly to fix the EL detector 1 in the upper middle position of the fixed plate 11, thereby playing a role in assembling the portable EL detector.

[0031] The plug-in rod 24 is composed of an elliptical plate, a long thick rod and two short thin rods. The long thick rod and the two short thin rods are fixed on one side of the elliptical plate. The two short thin rods are located on both sides of the long thick rod. An installation thread is provided at one end of the long thick rod away from the plug-in rod 24, and the installation thread cooperates with a No. 1 nut 25. When assembling the connecting block 21 and the connecting plate 22, first insert the connecting plate 22 into the middle groove of the connecting block 21, hold the elliptical plate of the plug-in rod 24, and insert the long thick rod and the two short thin rods into the holes opened in the connecting block 21. The long thick rod and the two short thin rods penetrate one side of the connecting block 21 and After the connecting plate 22, the long thick rod and the two short thin rods continue to be inserted into the other side of the connecting block 21. The length of the long thick rod is longer than the length of the two short thin rods. The No. 1 nut 25 is installed in conjunction with the mounting thread of the long thick rod to realize the assembly of the connecting block 21 and the connecting plate 22. At the same time, when storing the portable EL detector, the thread of the No. 1 nut 25 is loosened, and the two short thin rods are pulled out of one side of the connecting block 21. At this time, the long thick rod still penetrates the connecting plate 22 and is inserted into both sides of the connecting block 21. The square tube 23 can be rotated and folded in conjunction with the connecting plate 22, which is convenient for quick storage in the portable box and subsequent quick assembly.

[0032] The lifting assembly includes a sliding frame 3, a limiting hole 31 and a limiting plug rod 32; the sliding frame 3 is slidably connected to the inner wall of the square tube 23, and the top of the sliding frame 3 is fixed to the bottom end of the bottom plate; a plurality of the limiting holes 31 are provided on the outer wall of the square tube 23; the interior of the sliding frame 3 is slidably connected to the limiting plug rod 32 through a No. 1 elastic member, and the diameter of the limiting plug rod 32 corresponds to the diameter of the limiting hole 31; when the height of the EL detector 1 is adjusted to align with the solar panel detection, the two limiting plug rods 32 on both sides of the square tube 23 are pressed to retract into the interior of the square tube 23, and the limiting plug rods 32 The elastic member No. 1 between the sliding frame 3 contracts and is stressed, grabbing the outer wall of the sliding frame 3 and pulling it upward, and the sliding frame 3 slides on the inner wall of the square tube 23, and the limit rod 32 leaves a limit hole 31. After the EL detector 1 is adjusted to align with the solar panel, the elastic force of the elastic member No. 1 is reset to squeeze the limit rod 32 to slide, and the limit rod 32 slides and is inserted into another limit hole 31, which has the effect of raising the height of the EL detector 1. At the same time, after the limit rod 32 on the square tube 23 is released, the sliding frame 3 slides down and then limits the position, which has the effect of lowering the height of the EL detector 1.

[0033] like Figures 1 to 3 As shown, the outer walls of the plurality of cone rods 13 are provided with rotating threads; the outer walls of the plurality of cone rods 13 are rotatably connected with support plates 4, and the support plates 4 correspond to the rotating threads; when the portable EL detector is used on an uneven ground, the four cone rods 13 are respectively inserted into the uneven ground. At this time, the exposed lengths of the four cone rods 13 are inconsistent, and the four support plates 4 are respectively threadedly rotated, and the support plates 4 cooperate with the rotating threads, so that the four support plates 4 are respectively fitted to the uneven ground, thereby improving the stability of the portable EL detector during use. At the same time, when the portable EL detector is placed on a hard and stable ground such as a cement floor and an asphalt road, the four cone rods 13 are difficult to be nailed into the ground, and the four support plates 4 are threadedly rotated until they are level with the ground, so that the portable EL detector is easy to use on a hard and stable ground.

[0034] like Figures 1 to 4As shown, the outer walls of the two support frames 12 are rotatably connected to the first rotating plate 5; the outer walls of the two support frames 12 are rotatably connected to the second rotating plate 51, and the second rotating plate 51 and the first rotating plate 5 are arranged opposite to each other; the two first rotating plates 5 are plugged with a cross bar 52, and the cross bar 52 simultaneously penetrates the two first rotating plates 5 and the two second rotating plates 51; the outer wall of the cross bar 52 is threadedly connected to the second nut 53; when the portable EL detector is assembled and used, the first rotating plate 5 on the two support frames 12 is rotated close to the second rotating plates rotating on the other two support frames 12. Plate 51, overlap the ends of the No. 1 rotating plate 5 and the No. 2 rotating plate 51, use a cross bar 52 to simultaneously penetrate the two overlapping groups of No. 1 rotating plates 5 and No. 2 rotating plates 51, and cooperate with the No. 2 nut 53 to be threadedly installed on the cross bar 52, so as to play a role in supporting the four support frames 12, thereby improving the stability of the portable EL detector during use. At the same time, when disassembling the portable EL detector for carrying, remove the cross bar 52 and the No. 2 nut 53, and rotate the No. 1 rotating plate 5 and the No. 2 rotating plate 51 to fit on the outer wall of the support frame 12 for storage, which is convenient for the portable EL detector to be stored and carried.

[0035] like Figures 1 to 3 As shown, the inner walls of the four support frames 12 are slidably connected with sliding blocks 6, and the four sliding blocks 6 are located below the sliding plate 2; the outer walls of the sliding blocks 6 are rotatably connected with the rotating shaft 61; the outer wall of the rotating shaft 61 is fixedly connected with rollers 62; when the portable EL detector detects a solar panel and moves a short distance to detect other solar panels, the sliding plate 2 can be lowered, and the sliding plate 2 slides down to squeeze the four sliding blocks 6 to slide down synchronously, so that the four rollers 62 can pass over the bottom end of the cone rod 13 and fit the ground, the positioning component limits the sliding plate 2, and pushes the portable EL detector, which relies on the four rollers 62 to rotate on the four rotating shafts 61 respectively, so as to play a role in moving the portable EL detector over a short distance.

[0036] A fixing rod 7 is fixedly connected to the inner wall of the support frame 12, and the fixing rod 7 passes through the sliding block 6; a No. 2 elastic member 71 is fixedly connected between the sliding block 6 and the inner wall of the support frame 12, and the No. 2 elastic member 71 is sleeved on the fixing rod 7; when four rollers 62 are used to assist the portable EL detector to move a short distance, the sliding plate 2 squeezes the four sliding blocks 6 and slides down under the outer walls of the four fixing rods 7, and the four No. 2 elastic members 71 shrink and bear the force. At this time, the four rollers 62 roll in contact with the ground, and the portable EL detector moves a short distance. After the portable EL detector finishes moving, the sliding plate 2 slides up and is limited by the positioning assembly, and the four No. 2 elastic members 71 squeeze the four sliding blocks 6 to reset, thereby quickly resetting the four rollers 62.

[0037] like Figure 1 and Figure 6As shown, a raindrop sensor is installed on the outer wall of the EL detector 1; a storage box 8 is fixedly connected to the bottom end of the base plate; a collecting groove is opened on one side of the storage box 8; an airbag 81 is installed inside the collecting groove; when the portable EL detector is used outdoors, since the portable EL detector is easily damaged by rain, the storage box 8 is fixed under the base plate, and when the raindrop sensor installed on the EL detector 1 detects rain, the raindrop sensor sends a signal to the controller. The raindrop sensor is a sensor for monitoring rain. The raindrop sensor is not shown in the figure. The controller controls the airbag 81 to quickly expand from the collecting groove, which is similar to the safety warning system of a car. The expansion of the airbag 81 can surround and shield the EL detector 1. The expansion of the airbag 81 will not cause damage to the EL detector 1, reducing the damage caused by rain to the EL detector 1. After the rain stops, the airbag 81 is rearranged and stored in the storage groove and waits for the next use.

[0038] like Figures 1 to 3 As shown, the bottom ends of the plurality of support plates 4 are fixed with friction protrusions; the thickness of the support plates 4 is consistent with the tapered length of the cone rod 13; when four support plates 4 are used in contact with the ground, the friction protrusions are used to increase the friction between the support plates 4 and the ground, thereby improving the stability of the portable EL detector when it is placed in use; the thickness of the support plates 4 is consistent with the bottom cone length of the cone rod 13, and the cone rod 13 can be stored when the portable EL detector is placed on a flat ground, thereby ensuring that the portable EL detector is placed stably.

[0039] Working process: when using the portable EL detector to detect the laid solar panels, first take out 11 from the portable box, fix four 12 at the four corners of the bottom end of 11 respectively, use a hammer to hammer 11 several times, and nail 13 fixed at the bottom ends of multiple 12 into the bumpy and complex ground respectively, so that the upper end surface of 11 remains horizontal, and the connecting mechanism is installed on the multiple 12 outer walls below 11, and 1 is fixed on the bottom plate, and 1 is connected to 11 through the connecting mechanism to achieve the function of stable assembly of the portable EL detector, and 1 is aligned with the laid solar panels for detection, which is suitable for use on bumpy and complex ground, and reduces the possibility of the portable EL detector falling and being damaged during use. At the same time, after the portable EL detector is used, it will be disassembled and placed in the portable box for carrying; when assembling the portable EL detector, 2 is slidably installed on the outer walls of the four 12, and 2 is assisted in assembly by the positioning component, which is not shown in the figure. The positioning component is used to release the limit when 2 slides on the four 12 outer walls and stops at 2 When sliding on the four 12, 2 is limited, 22 at the bottom of 23 is inserted into the middle of 21, 21 and 22 are penetrated through 24, and 25 is used to connect 24 with the lifting assembly to fix 1 at the upper middle position of 11, which plays the role of assembling the portable EL detector; when assembling 21 and 22, first insert 22 into the middle groove of 21, hold the elliptical plate of 24 and insert the long thick rod and the two short thin rods into the holes opened in 21, and the long thick rod and the two short thin rods penetrate 2 After the one side of 1 and 22, the long thick rod and the two short thin rods continue to be inserted into the other side of 21, the length of the long thick rod is longer than the length of the two short thin rods, 25 is installed in conjunction with the mounting thread of the long thick rod to achieve the function of assembling 21 and 22. At the same time, when the portable EL detector is stored, the thread of 25 is loosened, and the two short thin rods are pulled out of one side of 21. At this time, the long thick rod still penetrates 22 and is inserted into both sides of 21. 23 can be rotated and folded in conjunction with 22, which is convenient for rapid storage in the portable box and subsequent rapid assembly;

[0040] When the height adjustment of 1 is aligned with the solar panel detection, the two 32 on both sides of 23 are pressed and retracted into the interior of 23, and the elastic member No. 1 between 32 and 3 is contracted and stressed, grabbing the outer wall of 3 and pulling upward, 3 slides on the inner wall of 23, and 32 leaves a 31. After 1 is adjusted to align with the solar panel, the elastic force of the elastic member No. 1 is reset to squeeze 32 to slide, and 32 slides and correspondingly inserts into another 31, which plays a role in raising the height of 1. At the same time, after the limit of 32 on 23 is released, 3 slides down and limits the rear position, which plays a role in lowering the height of 1.

[0041] When the portable EL detector is used on an uneven ground, the four 13 are respectively inserted into the uneven ground. At this time, the exposed lengths of the four 13 are inconsistent. The four 4 are respectively threadedly rotated, and the 4 cooperates with the rotating thread to make the four 4 fit the uneven ground respectively, thereby improving the stability of the portable EL detector when in use. At the same time, when the portable EL detector is placed on a hard and stable ground such as a cement floor and an asphalt road, the four 13 are difficult to be nailed into the ground. The four 4 are threadedly rotated until they are level with the ground, so that the portable EL detector is easy to use on a hard and stable ground.

[0042] When the portable EL detector is assembled for use, the 5 on the two 12s are rotated close to the 51 rotated on the other two 12s, and the ends of 5 and 51 are overlapped, and 52 is used to penetrate the two overlapping groups of 5 and 51 at the same time, and 53 is threadedly installed on 52, which plays a role in supporting the four 12s, thereby improving the stability of the portable EL detector when in use. At the same time, when the portable EL detector is disassembled for carrying, 52 and 53 are removed, and 5 and 51 are rotated and fitted on the outer wall of 12 respectively for storage, which is convenient for the storage and carrying of the portable EL detector;

[0043] When the portable EL detector detects a solar panel and then moves a short distance to detect other solar panels, 2 can slide down, and the downward movement of 2 squeezes the four 6 to slide down synchronously, so that the four 62 can pass the bottom end of 13 and fit the ground, and the positioning component limits 2 to push the portable EL detector, and the four 62 rotate on the four 61 respectively, so as to move the portable EL detector a short distance; when the four 62 are used to assist the portable EL detector to move a short distance, 2 squeezes the four 6 to slide down the outer wall of the four 7, and the four 71 contracts and bears the force, at this time, the four 62 fits the ground and rolls, so that the portable EL detector moves a short distance, and after the portable EL detector finishes moving, 2 slides up and is limited by the positioning component, and the four 71 squeezes the four 6 to reset, so as to quickly reset the four 62;

[0044] When the portable EL detector is used outdoors, since the portable EL detector is easily damaged by rain, 8 is fixed under the bottom plate. When the raindrop sensor installed on 1 detects rain, the raindrop sensor sends a signal to the controller. The raindrop sensor is a sensor for monitoring rain. The raindrop sensor is not shown in the figure. The controller controls 81 to quickly expand from the collection groove, which is similar to the safety warning system of a car. 81 expands to surround and shield 1. 81 does not cause damage to 1 when it expands, reducing the damage caused by rainwater to 1. After the rain stops, 81 is reorganized and stored in the storage groove and waits for the next use.

[0045] When four 4 are used in contact with the ground, the friction between 4 and the ground is increased by the friction protrusions, thereby improving the stability of the portable EL detector when placed in use. The thickness of 4 is consistent with the bottom cone length of 13, and 13 can be stored when the portable EL detector is placed on a flat ground, ensuring that the portable EL detector is placed stably.
