[0019] Figures 1 to 3 As shown in the figure, it relates to a device for detecting the flatness of a highway pavement, including a vehicle body 1. A threaded pipe 2 is connected through the center position of the upper surface of the vehicle body 1 in a threaded manner. A working box 3 is rotatably connected inside the threaded pipe 2. A detection mechanism is installed inside the working box 3. An adjustment mechanism is installed on the top of the detection mechanism. A reminder device that cooperates with the detection mechanism is installed on the upper surface of the vehicle body 1. A cleaning mechanism is installed on one side of the outer surface of the vehicle body 1. A rotating ring 26 is sleeved and fixedly connected to the outer surface of the threaded pipe 2, and anti-slip lines are provided on the outer surface of the rotating ring 26.

[0020] The detection mechanism includes a vertical rod 4. The vertical rod 4 penetrates through the bottom of the working box 3 and is slidably connected to the working box 3. A contact plate 5 is sleeved and fixedly connected to the outer surface of the vertical rod 4. A support plate 6 is fixedly connected to the inner wall of the working box 3 at a position above the contact plate 5. A first spring 7 and a second spring 8 are respectively fixedly connected to the lower surface of the support plate 6 and the inner bottom of the working box 3. The other ends of the first spring 7 and the second spring 8 are respectively fixedly connected to a first mounting plate 9 and a second mounting plate 10. A first touch switch 11 and a second touch switch 12 are respectively fixedly installed on the lower surface of the first mounting plate 9 and the upper surface of the second mounting plate 10. A guide wheel 13 is installed at the bottom end of the vertical rod 4. When encountering an uneven ground, at this time the vertical rod 4 will rise or fall, and then drive the contact plate 5 to contact the first touch switch 11 or the second touch switch 12.

[0021] The adjustment mechanism includes a screw 14. The screw 14 penetrates through the top of the working box 3 and is threadedly connected to the working box 3. The bottom end of the screw 14 is rotatably connected to a bottom plate 15 that is slidably connected to the inner wall of the working box 3. A third spring 16 is fixedly connected between the lower surface of the bottom plate 15 and the top end of the vertical rod 4. The top end of the screw 14 is fixedly connected to a knob 17. Rotating the knob 17 drives the screw 14 to rotate, thereby compressing the third spring 16 through the bottom plate 15.

[0022] The reminder device includes a controller 18 and two speakers 19. The first touch switch 11, the second touch switch 12, and the two speakers 19 are all electrically connected to the controller 18 through wires. When the controller 18 receives the signal from the first touch switch 11 or the second touch switch 12, it controls the activation of a single speaker 19, thus facilitating the identification of road conditions.

[0023] The cleaning mechanism includes a cross plate 20. The cross plate 20 is fixedly installed on one side of the vehicle body 1. An air duct 21 is fixedly installed through the outer surface of the cross plate 20. The bottom end of the air duct 21 is fixedly connected to a cross pipe 22. A plurality of nozzles 23 are sequentially fixedly installed on the outer surface of the cross pipe 22. A blower 24 is fixedly installed on the upper surface of the vehicle body 1. The air outlet end of the blower 24 is fixedly connected to one end of the air duct 21. The air generated by the blower 24 is blown to the nozzles 23 through the air duct 21 and the cross pipe 22, thereby cleaning the ground.

[0024] An L-shaped rod 25 is fixedly connected to the outer surface of the work box 3. One end of the L-shaped rod 25 penetrates through the vehicle body 1 and is slidably connected to the vehicle body 1 to prevent the work box 3 from rotating.

[0025] Moving wheels 27 are installed on the lower surface of the vehicle body 1, and a handrail 28 is fixedly installed on one side of the upper surface of the vehicle body 1.

[0026] When using the highway road surface flatness detection device, first install the work box 3 on the vehicle body 1 through the rotating ring 26, and then rotate the knob 17. The rotation of the knob 17 drives the screw rod 14 to rotate, thereby compressing the third spring 16 through the bottom plate 15, so that the guide wheel 13 at the bottom of the vertical rod 4 presses against the ground surface. Then start the blower 24. The air generated by the blower 24 is blown to the nozzles 23 through the air duct 21 and the cross pipe 22, thereby cleaning the ground. Then move the device through the handrail 28. When the ground is convex or concave, at this time, the vertical rod 4 is driven to move upward or downward by the guide wheel 13, so that the contact plate 5 contacts the first touch switch 11 above or the second touch switch 12 below. At this time, the controller 18 receives the signal from the first touch switch 11 or the second touch switch 12 and controls the activation of a single speaker 19, thus facilitating the identification of road conditions.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
