[0025] Working principle: Two electrical cabinet panels of the same size are taken from the same electrical control cabinet and placed in the clamping blocks 382 of the first conveying mechanism 3 and the second conveying mechanism 4 respectively. Then, the first lead screw 365 is controlled to rotate. Under the transmission of the first lead screw 365, the rotating plate 38 will start to move. When the limiting rotating block 383 moves in the horizontal slide groove 37, the electrical cabinet panel will translate horizontally. When the limiting rotating block 383 moves into the rotating groove 371, the toothed plate 381 will contact the rack 366 and the electrical cabinet panel will start to rotate. At the same time, the flushing plate 361 will start to spray cleaning. The electrical cabinet panel is washed to achieve the effect of rotating and cleaning. Then, it moves to the horizontal slide 37 again. The limit block 383 will return to the horizontal state. When it moves to the appropriate position, the electrical cabinet panel will contact the transmission roller 363. At this time, the clamping block 382 will be released. Under the connection of the transmission roller 363, the electrical cabinet panel will be conveyed into the wiping roller 364. After wiping, it will enter another transmission roller 363 and finally be directly conveyed to the test tank 62. Then, the flipped test plate 6 will be rotated upward by 90 degrees so that the limit post 61 enters the vibration tank 14. Then, the position of the limit block 63 will be adjusted to close the sealing opening. Thickness test: Control the electric screws inside the two flip test plates 6 to move, the test frame 64 will start to move upward, and under the action of the spring, one end of the test roller 641 will be connected to the electrical cabinet plate. At this time, the length of the scale at the end of the test roller 641 can be recorded, and during the continuous movement, observe whether the scale changes. If the length changes, the thickness of the two electrical cabinet plates is different and they need to be replaced and tested again. If everything remains consistent, the testing rack 64 on one side can be retracted to its original position. Then, the limiting block 63 is opened, and the flip test plate 6 is rotated back to a horizontal position. The electrical cabinet plate is then pushed forward, and it will reconnect to the transmission roller 363. The cleaning operation described above is repeated. The electrical cabinet plate moves to its original position, and the driving adjustment motor 33 rotates. The eccentric wheel 34 starts to rotate, and the support base block 35 continues to descend following the position of the eccentric wheel 34. When the electrical cabinet plate reaches the top surface of the material placement tray 51, the electric adjustment motor... Machine 33 stops rotating, control clamping block 382 releases, and the electrical cabinet panel falls into the material placement tray 51 and onto the protective frame 52. Then, the salt spray chamber 5 closes to simulate the environment for the electrical cabinet panel. After a period of time, the electrical cabinet panel is taken out and placed back into clamping block 382. The cleaning and wiping process is repeated. The electrical cabinet panel enters the test slot 62. Then, the test plate 6 is rotated and flipped, and the limiting block 63 is closed again. The thickness test is repeated. At this time, the changes can be clearly seen by comparing the scale of the test roller 641.

Adjusting plates 251 are movably connected within the adjusting groove 243 to change the distance between the adjusting ring 25 and the rotating disk 24, thereby achieving the effect of adjusting the vibration frequency. The adjusting ring 25 is fixedly installed on the bottom end of multiple adjusting plates 251. Multiple trapezoidal blocks 252 are fixedly installed on the top surface of the adjusting ring 25, which allows the roller 221 to roll upward along one side of the trapezoidal block 252 and then fall from the other side of the trapezoidal block 252, repeating multiple times to achieve the effect of back-and-forth vibration. The trapezoidal blocks 252 are matched with the position of the lifting groove 241. Adjusting holes are opened on the adjusting plates 251. First positioning bolts 242 are installed on the rotating disk 24 on one side of the adjusting groove 243. The first positioning bolts 242 are threaded into the adjusting holes to achieve the effect of limiting the adjustment ring 25.

[0028] Working principle: When performing static load testing, mounting plates are fixed on one side of two electrical cabinet panels for comparison. Then, the test frame 64 is adjusted to the middle position of the electrical cabinet panel. Weight blocks 13 of equal weight are placed on the mounting plates of the electrical cabinet panels one by one in an increasing trend. As they are placed, the weight borne by the mounting plates will increase. The electrical cabinet panels will gradually begin to bend and deform under stress. The test roller 641 connected to the rear side of the electrical cabinet panel will adjust according to the curvature of the electrical cabinet panel. When the same weight is placed on both sides, the difference between the electrical cabinet panel after salt spray simulation and the normal electrical cabinet panel can be clearly observed. During dynamic load testing, weight blocks 13 of equal weight are placed on the mounting plates on both sides. The distance between the rotating disk 24 and the adjusting ring 25 is adjusted so that a small portion of the trapezoidal block 252 protrudes from the rotating disk 24. Then, the rotary motor 21 is controlled to rotate, thereby driving the rotating disk 24 to rotate. During the rotation, the roller 221 repeatedly moves onto the trapezoidal block 252 and then falls, achieving rapid lifting and lowering of the vibratory disk 23 to achieve continuous vibration. After a period of time, the vibration is stopped, and the difference in curvature between the two electrical cabinet panels is observed through the scale of the test roller 641. After recording, the rotating disk 24 is adjusted multiple times. 4. Adjust the distance between the rings 25 and the rotation speed of the rotary motor 21 for further testing. Gradually raise the protrusion of the trapezoidal block 252 to increase the vibration amplitude. Changes in motor speed can adjust the vibration frequency. After performing the above operations again, the test results will be more obvious. In addition, the test also saves the simulation test of the electrical control cabinet in the transportation and vibration environment. Under high vibration frequency and amplitude, the stability of the position of the weight block 13 can be seen, and whether the weight block 13 will fall off. Thus, the risk of electrical cabinet components falling off due to vibration can be tested.

[0029] Example 3: Reference Figure 17-18 Based on Embodiment 2, the following technical solutions are also provided: In this embodiment, the impact component 7 includes an impact frame 71, an arc-shaped guide frame 76, and an impact ball 75. The impact frame 71 is fixedly installed on both sides of the arc-shaped guide frame 76 to facilitate the installation of the impact component 7. Multiple limiting screws 77 are installed on the arc-shaped surface of the outer side of the arc-shaped guide frame 76. One end of the limiting screw 77 passes through the inner side of the arc-shaped guide frame 76 and acts on the limiting of the impact ball 75 at different heights, thereby achieving the test effect of different impact forces. A fixing rod 73 is welded and installed between the impact frames 71. A limiting ring 74 is rotatably connected to the outer surface of the fixing rod 73 to ensure the fixed point of the center of the impact ball 75. A pull rope is connected between the limiting ring 74 and the impact ball 75. A wire groove is opened on the arc-shaped surface of the inner side of the arc-shaped guide frame 76. A positioning screw 72 is provided on both ends of the impact frame 71. Two sets of threaded holes are correspondingly provided on the top surfaces of the side plate frame 12 and the intermediate frame 15 to facilitate the disassembly and installation of the impact component 7. The positioning screw 72 is connected in the threaded hole.

[0030] Working principle: When conducting an impact test, two electrical cabinet panels can be placed, and the impact frame 71 can be installed between the side panel frame 12 and the middle frame 15 on one side. Then, the position of the bottom limit screw 77 is adjusted, and the impact ball 75 is placed into the arc-shaped guide frame 76. After releasing the limit screw 77, the impact ball 75 will impact the electrical cabinet panel. After the impact is completed, the detection frame 64 is moved and the electrical cabinet panel is measured by the test roller 641. Then, the position of the impact frame 71 is adjusted to conduct the same impact test on the electrical cabinet panel on the other side. After the test is completed, the detection frame 64 is also used for measurement. Then, the above test is repeated by adjusting different limit screws 77 to adjust the impact force. After multiple sets of tests, the difference between the electrical cabinet panel after salt spray simulation and the ordinary electrical cabinet panel can be seen. When conducting component impact tests, both are placed and fixed with mounting plates, and the same weight block 13 is placed on them. Then, the above-mentioned impact tests at different heights are repeated. Under the increasing impact, it is possible to directly observe whether the weight block 13 on the two electrical cabinet plates will be affected by external impact and fall off. This can simulate the position and falling situation of internal components of the electrical control cabinet after being impacted.
