A cleaning component 7 is provided inside the guide groove 106. The actuator of the cleaning component 7 is located below the box body 1.

[0024] When conducting a permeability test on the ground of a highway, the staff first pushes the box body 1 to the top of the test area through the moving wheels 102, and then starts the driving source in the cleaning component 7 through the control panel. The executive part sweeps away the impurities on the ground of the test area to prevent the impurities from affecting subsequent tests. Then, the covering shell is selected as needed. When the first covering shell 2 is used, the driving source in the driving component 5 is started through the control panel, so that the executive part works to push the first covering shell 2 out of the receiving groove 101 and move it toward the ground until the first sealing gasket 201 is in close contact with the ground.

The downward moving protective shell 501 drives the internal dual-axis motor 5011 to move, so that the two rotating shafts 502 move and drive the vertical bevel gear 5021 to separate from the horizontal bevel gear 5031. The movement of the two rotating shafts 502 will also drive the mounting block 601 to move downward.

At this time, the L-shaped plate 602 that continues to move downward will push the pressure rod 604 to move, and the pressure rod 604 will push the second covering shell 3 to move downward, and the second covering shell 3 will drive the guide plate 303 to move along the guide rod 203 through the vertical plate 302, so that the annular magnet 3031 is separated from the iron sheet on the inner top wall of the first covering shell 2, and the downward-moving second covering shell 3 will stretch the reset spring 6041 until the second covering shell 3 moves out of the first covering shell 2 and the second sealing gasket 301 at its bottom is in close contact with the ground.

[0031] The working principle of the present invention is: When conducting a permeability test on the ground of the highway, the staff first pushes the box body 1 to the top of the detection area through the moving wheel 102, and then starts the electric slide rail 701 in the cleaning component 7 through the control panel, so that the slider 702 moves along the electric slide rail 701 in the guide groove 106, and the moving slider 702 drives the connecting plate 703 to move, and the connecting plate 703 drives the bottom cross plate 704 to move between the box body 1 and the ground, and the moving cross plate 704 drives the brush 7041 on the lower side to clean the impurities on the ground, and then selects the covering shell as needed. When the first covering shell 2 is used, the driving component 5 is started through the control panel. The dual-axis motor 5011 works, and its two output ends respectively drive the rotating shaft 502 to rotate. The two rotating shafts 502 both drive the vertical bevel gears 5021 at the ends to rotate. The two vertical bevel gears 5021 both drive the meshing transverse bevel gears 5031 to rotate. The two transverse bevel gears 5031 both drive the vertical shaft 503 passing through the center to rotate. The threaded rod 504 at the bottom of the vertical shaft 503 rotates accordingly. At this time, the square threaded sleeve 505 moves vertically following the rotation of the threaded rod 504, pushing the bottom connected to the first covering shell 2 to move out of the storage groove 101 until the first sealing gasket 201 is in close contact with the ground, completing the coverage of the first covering shell 2 with the ground. When the second covering shell 3 is used, the hydraulic cylinder 605 in the pressing assembly 6 is started to work through the control panel, and its telescopic end pushes the pressing plate 6051 downward, and the pressing plate 6051 drives the protective shell 501 to move downward. The downward moving protective shell 501 drives the internal dual-axis motor 5011 to move, so that the two rotating shafts 502 move and drive the vertical bevel gear 5021 to separate from the horizontal bevel gear 5031, and the movement of the two rotating shafts 502 will also drive the mounting block 601 to move downward. The two mounting blocks 601 are both in contact with the inner wall of the protective shell 104 through the end of the limiting rod 603 to avoid rotating with the rotating shaft 502. The movement of the two mounting blocks 601 will drive the L set on the top The profile plate 602 moves downward, and after the downwardly moving L-shaped plate 602 contacts the top end of the pressure rod 604, the rubber pad 6021 can reduce wear. At this time, the continuously downwardly moving L-shaped plate 602 will push the pressure rod 604 to move, and the pressure rod 604 will push the second cover shell 3 downward. The second cover shell 3 will drive the guide plate 303 to move along the guide rod 203 through the vertical plate 302, so that the annular magnet 3031 is separated from the iron sheet on the inner top wall of the first cover shell 2. The downwardly moving second cover shell 3 will stretch the return spring 6041 until the second cover shell 3 moves out of the first cover shell 2 and the second sealing gasket 301 at its bottom is in close contact with the ground, completing the coverage of the second cover shell 3 and the ground. Then, a permeability test is performed. The water pump 1031 and the solenoid valve on the corresponding water supply hose 1032 are started through the control panel. The water pump 1031 draws the water in the water tank 103 into the corresponding covering shell through the water supply hose 1032 opened by the solenoid valve until the water is submerged in the ground. The water level sensor detects the initial height of the water and transmits it to the control panel for display. After standing for a period of time, the current water level is detected by the water level sensor. The permeability of the ground can be detected by the difference between the two height data.
