DETAILED DESCRIPTION

[0019] The utility model will be described in detail below in combination with the drawings and examples.

[0020] Example: a road surface flatness instrument, as shown in Figure 1 and Figure 2 , including a telescopic frame body 1, the length of frame body 1 can be adjusted to ensure the accuracy and stability of measurement, the bottom of frame body 1 is equipped with a pair of front wheel group 2, a pair of rear wheel group 3 and a measuring wheel 4, the top surface of frame body 1 is fixedly connected with a storage basket 22, the data collector 5 is clamped in the storage basket 22, so as to avoid the data collector 5 from falling due to the shaking of frame body 1, eight wheels on the pair of front wheel group 2 and the pair of rear wheel group 3 can provide more uniform support, reduce the shaking of frame body 1 on uneven road surface, and further improve the stability of measurement.

[0021] As shown in Figures 1-3 , the bottom of frame body 1 is equipped with a cleaning assembly 6, the cleaning assembly 6 is located between the front wheel group 2 and the measuring wheel 4, the cleaning assembly 6 includes an electric push rod one 10, two telescopic rods one 11 and a brush strip one 12, the two ends of the electric push rod one 10 and the two telescopic rods one 11 are fixedly connected with the top surface of brush strip one 12 and the bottom surface of frame body 1 respectively, the brush strip one 12 can be driven to move up and down by the electric push rod one 10, the electric push rod one 10 is located in the middle of brush strip one 12, and the two telescopic rods one 11 are located on the two sides of electric push rod one 10 respectively, so as to ensure the stability of brush strip one 12 during movement, the brush strip one 12 can be driven to move downward to abut against the road surface by the electric push rod one 10, the cross-sectional shape of brush strip one 12 is V-shaped, so that the brush strip one 12 can sweep the stones and other sundries on the road surface to the two sides of the length of frame body 1 when moving together with frame body 1, the sweeping area of brush strip one 12 can cover the movement path of measuring wheel 4, avoiding that the stones or sundries remaining on the road surface hinder the normal rolling of measuring wheel 4 on the road surface, and ensuring the detection accuracy of measuring wheel 4.

[0022] As shown in Figure 1 , Figure 2 and Figure 4As shown, a bracket 7 is welded to the tail end of the frame 1. A powder spraying device 8 and a marking component 9 are provided at the bottom of the bracket 7. The powder spraying device 8 is located between the measuring wheel 4 and the marking component 9. The powder spraying device 8 includes a storage tank 13, a powder supply pump 14 and a nozzle 15. The top surface of the storage tank 13 is welded to the connection between the frame 1 and the bracket 7, thereby ensuring the fixation effect of the bracket 7 and the frame 1. The powder supply pump 14 can draw the powder in the storage tank 13 and deliver it to the nozzle 15 for spraying. The powder supply pump 14 is equipped with a control module 16 that is connected to the data acquisition device 5 via Bluetooth. When the detection value of the data acquisition device 5 exceeds the set value, it will immediately send a signal to the control module 16, at which time the powder spraying device 8 sprays out powder.

[0023] like Figures 1-4 As shown, the marking component 9 includes an electric push rod 17, two telescopic rods 18, and a brush strip 19. The two ends of the electric push rod 17 and the two telescopic rods 18 are fixedly connected to the top surface of the brush strip 19 and the bottom surface of the bracket 7, respectively. The electric push rod 17 can drive the brush strip 19 to move up and down. The electric push rod 17 is located in the middle of the brush strip 19, and the two telescopic rods 18 are located on both sides of the electric push rod 17, thus ensuring the stability of the brush strip 19 during movement. The electric push rod 17 can also drive the brush strip 19 downwards until it touches the road surface. The cross-sectional shape of the brush strip 19 is straight, and the smoothing range of the brush strip 19 is larger than the spraying range of the powder spraying device 8. The brush strip 19 can smooth out the powder sprayed by the powder spraying device 8. The marking area is formed within a certain range, and the marking area formed after being smoothed with powder is clear and conspicuous, with a long retention time, which facilitates subsequent rectification of problem areas by staff. Since the powder spraying device 8 is set between the measuring wheel 4 and the second brush 19, it can avoid the measuring wheel 4 from contacting the powder and affecting the measurement accuracy. At the same time, it can ensure that the second brush can smooth the powder sprayed in front of it onto the required marking area. A control panel is set on the side of the frame 1. The first electric push rod 10 and the second electric push rod 17 are each equipped with a control module 21 that is connected to the control panel 20 via Bluetooth. The first brush 12 and the second brush 19 can be driven up and down through the control panel 20. The operation is simple and can mark the problem area in real time without stopping the measurement work, thus improving the measurement efficiency.

[0024] Working principle: The control panel 20 sends signals to the two control modules 21, causing the electric push rods 10 and 17 to stretch, thereby driving the brush strips 12 and 19 to move downwards until they touch the ground. The brush strip 12 can remove stones or other debris from the path in front of the measuring wheel 4, thus ensuring the measurement accuracy of the measuring wheel 4. When the detection value received by the data acquisition unit 5 exceeds the set value, it sends a signal to the control module 16, thereby driving the powder spraying device 8 to spray powder. The brush strip 19 then smooths the powder sprayed by the powder spraying device 8, thus forming a marked area within a certain range.
