The working principle is as follows: when the detection device is used, the detection device is pushed to a road surface needing to detect the ground flatness through the pushing frame 3, the marking liquid is poured into the connecting frame 403, the detection device is pushed to move on the detection ground, and if the ground is not sunken or raised, or the range of the sunken or raised does not affect the ground flatness in a normal range, the detection device can be moved from one section to one section on a detection road section to finish the detection;
if the ground flatness is poor, when the pulley 406 moves to a concave position, the connecting spring 415 pushes the sliding rod 416 to slide downwards to enable the pulley 406 to be in contact with the concave ground, the upper end of the sliding rod 416 drives the L-shaped transmission frame 417 to move downwards, the L-shaped connection frame 414 on the other side is driven to ascend through the meshing of the transmission gear 413, the fixed column 411 is jacked to ascend and lift up the sealing plate 410, so that the sealing plate 410 is opened from the upper end of the liquid storage cavity 418, the marking liquid in the connecting frame 403 flows into the liquid storage cavity 418 and flows out from the discharge pipe 408 on one side, and the time when the pulley 406 passes through the concave road surface is just the time when the marking liquid enters the liquid storage cavity 418 and flows out from the discharge pipe 408, so that the marking liquid flowing out from the discharge pipe 408 on one side after the pulley 406 passes through the concave surface can accurately drop into the concave ground to mark the concave surface;
when the pulley 406 moves to a convex ground, the bottom plate 405 and the support rod 404 ascend due to the contact between the bottom plate 405 and the protrusion and the compression of the return spring 401, the connecting plate 407 inside the connecting frame 403 ascends through the sliding rod 416 to pull the sealing plate 410 upwards, the marking liquid enters the liquid storage cavity 418 in the same way and then flows out from the discharge pipe 408 to mark the protrusion position, so that the convex and concave road sections can be effectively marked, the sliding fit between the sliding rod 416 and the sliding sleeve 419 is adopted, the strong spring 420 for sliding connection with the sliding rod 416 is arranged inside the sliding sleeve 419, so that when the convex road surface is met, the sliding sleeve 419 ascends, the sliding rod 416 is pulled upwards through the strong spring 420, the sealing plate 410 is pulled out for the marking liquid to flow into the liquid storage cavity 418, the elastic force of the strong spring 420 is larger than the gravity of the sliding rod 416 and the sealing plate 410, the sliding rod 416 and the sealing plate 410 are compressed to move downwards to enter the upper end of the liquid storage cavity 418 while moving downwards through the rear sliding sleeve 419, when a concave road surface is encountered, the sealing plate 410 is driven by transmission to ascend, so that the sliding rod 416 is driven to ascend to compress the strong spring 420, the sliding sleeve 419 is not driven to move, the detection on the concave and convex road surfaces cannot be linked, the smooth discharging pipe 408 is matched with the marking liquid which is not easy to adhere, the marking liquid can completely flow out after flowing in the discharging pipe 408 during marking, no residual part is adhered to the inner wall of the discharging pipe 408, and the problem that the marking liquid drips to continuously mark the road surface in the moving process can be solved;
after the detection is finished, the detection device is moved to the surface of a flat road section, the residual marking liquid in the connecting frame 403 is pumped out to clean the inside of the connecting frame 403, and the problem that the part of the marking liquid, which is in contact with the inner wall of the connecting frame 403, is solidified and dried and is inconvenient to clean is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
