The third electric slide rail 42 is slidably connected to a sliding cleaning brush 43 via an electronic slider. One side of the sliding cleaning brush 43 is slidably connected to the side wall of the filter screen 44.

[0037] It should be noted that when the suction pipe 45 draws out the cleaning fluid, the filter screen 44 prevents debris from entering the suction pipe 45. The third electric slide rail 42 and the sliding cleaning brush 43 can be used to clean the filter screen 44, preventing it from being clogged by debris.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] When the staff needs to conduct a load test on the commercial vehicle drive axle, the first electric slide rail 3 is activated. The first electric slide rail 3 drives the sliding door panel 4 to move and open the equipment. At the same time, the protective plate 6 protects the corners of the tempered glass 5 to prevent the tempered glass 5 from breaking during the commercial vehicle drive axle test. Start the hydraulic rod 8. The hydraulic rod 8 drives the clamping device 10 to extend out of the protective box 2 through the sliding base plate 9, making it more convenient for the staff to clamp the commercial vehicle drive axle. After the commercial vehicle drive axle is installed, the hydraulic rod 8 is driven to reset through the sliding base plate 9 and the clamping device 10, and the first electric push rod 12 is activated. The first electric push rod 12 extends into the limiting groove 11 to limit the sliding base plate 9, so as to prevent the commercial vehicle drive axle from shaking when the experimental device 14 tests the commercial vehicle drive axle, which would result in inaccurate test results. When the protective enclosure 2 tests the commercial vehicle drive axle, it isolates and protects the axle to prevent it from shattering and injuring personnel in the event of a test accident. The second electric slide rail 13, the experimental device 14, and the tempered glass 5 work together to conduct a multi-directional load test on the commercial vehicle drive axle. After the test is completed, the first high-pressure water pump 20 is activated. The first high-pressure water pump 20 sprays the cleaning fluid from the cleaning fluid storage tank 18 through the connecting pipe 19, the spray chamber 16, and the first high-pressure nozzle 17 to self-clean the inside of the protective enclosure 2.

The drive motor 22 drives the second high-pressure nozzle 29 to rotate through the rotating rod 23, the fixed circular plate 24, the second high-pressure water pump 26, the electric telescopic tube 27 and the spray ring 28. The electric telescopic tube 27 is started. The electric telescopic tube 27 drives the second high-pressure nozzle 29 to press down through the spray ring 28 to perform all-round cleaning on the inside. No staff need to use other equipment to clean the inside. After the inside of the protective box 2 is cleaned, the cleaning waste liquid flows into the fixed cylinder 32 through the drain outlet 7 and the waste liquid tank 30. The waste liquid and metal scrap can be separated and screened through the multiple filter holes 33. After the waste liquid is discharged from the filter holes 33, the vacuum distillation furnace 31 is started. The vacuum distillation furnace 31 removes water from the waste liquid through vacuum distillation. The waste liquid is then discharged through the drain pipe 39. After the waste liquid enters the adsorbent storage tank 41, the adsorbent in the adsorbent storage tank 41 removes polar impurities from the waste liquid to complete the purification of the waste liquid. The water pump 46 is started. The water pump 46 draws the cleaning liquid from the adsorbent storage tank 41 through the liquid extraction pipe 45 and inputs it into the cleaning liquid storage tank 18 through the liquid delivery pipe 47 to complete the cleaning liquid circulation and reduce the consumption of equipment cleaning liquid resources. The dustproof chamber 21 protects the drive motor 22, reducing dust from entering the drive motor 22 and causing damage. When the drive motor 22 drives the rotating rod 23 to rotate, the rotating rod 23 drives the stirring blade 25 to rotate and stir the cleaning solution, preventing the cleaning solution from settling inside the cleaning solution storage tank 18 and affecting the cleaning effect of the cleaning solution. When the waste liquid enters the fixed cylinder 32, the electric rotating rod 35 is activated. The electric rotating rod 35 drives the waste liquid to rotate through the rotating blade 36, and the waste liquid is thrown out of the fixed cylinder 32 by centrifugal force, thereby improving the waste liquid separation efficiency of the fixed cylinder 32. When the electric rotating rod 35 drives the rotating blade 36 to rotate, the rotating blade 36 drives the cleaning brush 37 to rotate and clean the inside of the filter hole 33 to prevent metal debris from clogging the filter hole 33. The metal debris inside the fixed cylinder 32 is weighed by the weighing plate 38. When the fixed cylinder 32 is full of metal debris, the staff is reminded to collect the metal debris inside the fixed cylinder 32. When the suction pipe 45 draws out the cleaning fluid, the filter screen 44 prevents debris from entering the suction pipe 45. The third electric slide rail 42 and the sliding cleaning brush 43 can be used to clean the filter screen 44, preventing it from being clogged by debris.
