[0011] Compared with the prior art, the traffic sign with a cleaning structure of the utility model has the following beneficial effects:

[0012] Dust and dirt on the signboard can be removed by the automatic cleaning structure without human intervention, saving human resources and time costs. By regularly cleaning the surface of the signboard, its clarity and visibility can be maintained, effectively providing accurate route guidance and information services, and improving the driver's driving experience and traffic safety. Traditional manual cleaning methods require the closure of part of the traffic flow, while traffic signs with a cleaning structure can be automatically cleaned during operation, reducing interference with traffic flow and improving maintenance efficiency: the automatic cleaning structure can be used to clean the signboard regularly, effectively reducing the frequency and maintenance cost of maintenance work and increasing the life of the signboard: regular cleaning and maintenance can extend the service life of the signboard, reduce the need for replacement and repair, and save maintenance costs.

The fixing frame 2 is provided with the driving box 3 and equipped with the stepping motor 13 to realize automatic driving, which is convenient for cleaning work.

[0020] The output end of the stepper motor 13 is connected to a driving gear 12, which meshes with the driven gear 11 for transmission. The stepper motor 13 drives the driving gear 12 to rotate, and the driving gear 12 meshes with the driven gear 11 for transmission. One end of the first cleaning roller 9 and the second cleaning roller 10 are respectively fixedly connected to the driven gear 11, thereby driving the first cleaning roller 9 and the second cleaning roller 10 to rotate synchronously, and utilizing friction to clean the surface of the identification plate 4. There is a gear difference between the driving gear 12 and the driven gear 11, which increases the stability of the transmission.

[0021] A lifting motor 5 is provided at the top of the support column 1, and a screw rod 6 is connected to the output end of the lifting motor 5. The screw rod 6 and the slider 8 are threadedly transmitted. The lifting motor 5 controls the rotation of the screw rod 6. The screw rod 6 and the slider 8 are threadedly transmitted. The slider 8 is vertically lifted and lowered along the guide rail 7, which is convenient for adjusting the height of the signboard 4.

[0022] The connecting end of the slider 8 and the support column 1 is symmetrically provided with guide rails 7, and the length of the guide rails 7 is the same as the length of the screw rod 6. Driven by the slider 8, the identification plate 4 can be inserted into the fixed frame 2, and the displacement caused by the lifting and lowering can enable the first cleaning roller 9 and the second cleaning roller 10 to comprehensively clean the dust on the surface of the identification plate 4.

[0023] Working principle: When it is necessary to clean the signboard 4, the starting position of the signboard 4 is at the highest end, and the lifting motor 5 and the stepper motor 13 are started. The stepper motor 13 drives the driving gear 12 to rotate, and the driving gear 12 is meshed with the driven gear 11 for transmission, and one end of the first cleaning roller 9 and the second cleaning roller 10 are respectively fixedly connected to the driven gear 11, thereby driving the first cleaning roller 9 and the second cleaning roller 10 to rotate synchronously. At the same time, the lifting motor 5 controls the rotation of the screw rod 6, and the screw rod 6 and the slider 8 are threadedly transmitted. The slider 8 is vertically lifted and lowered along the guide rail 7. During the lifting process, the signboard 4 is inserted from the inside of the fixed frame 2 from top to bottom. During the insertion process, the first cleaning roller 9 and the second cleaning roller 10 in a rotating state rub against the signboard 4, which can remove the sludge on the surface of the signboard 4, so that the cleaning work of the signboard 4 does not require human participation and will not affect the traffic flow.
