[0033] The lifting column 410 is fixed in the installation groove 310, and an upper end thereof is provided with a mounting frame 440 and can drive the mounting frame 440 to extend out of or retract into the installation groove 310. The lifting column 410 is preferably an electric screw lifting column.

[0034] The water spraying nozzle 420 is fixed in the mounting frame 440 and used for aiming at the license plate on the front side of the vehicle on the scale. A water supply hose 421 is connected to a water inlet end of the water spraying nozzle 420, and the water supply hose 421 is used for connecting a water spraying control mechanism.

[0035] It can be understood that the form of the water spraying control mechanism is not limited in the embodiment, and the water spraying control mechanism can be a water pump, the water spraying nozzle 420 sprays water through the opening and closing of the water pump, or can be an electromagnetic valve arranged on a pressure water pipe, the water spraying nozzle 420 sprays water through the opening and closing of the electromagnetic valve.

[0036] The license plate recognition camera 430 is fixed on the mounting frame 440 and used for photographing and recognizing the license plate on the front side of the vehicle on the scale.

[0037] As shown in Figure 1 , when the vehicle drives from the loading ramp 200 to the weight bridge 100, the vehicle can be weighed by the weight bridge 100, and the license plate on the front side of the vehicle can be recognized by the license plate recognition camera 430. If the license plate on the front side of the vehicle is polluted and recognized by the license plate recognition camera 430, the water spraying nozzle 420 can be controlled to wash the license plate on the front side of the vehicle, and the license plate on the front side of the vehicle is recognized again by the license plate recognition camera 430 after being washed, so as to ensure the accuracy of the license plate recognition. As shown in Figure 2 , after the license plate recognition is completed, the lifting column 410 drives the mounting frame 440 to descend, so as to hide the water spraying nozzle 420 and the license plate recognition camera 430 in the unloading ramp 300, so as not to hinder the vehicle from driving out of the unloading ramp 300. When the next vehicle drives to the weight bridge 100, the water spraying nozzle 420 and the license plate recognition camera 430 can be controlled to extend out of the installation groove 310 on the unloading ramp 300.

[0038] In some embodiments, the water spraying nozzle 420 can be horizontally swung left and right under the drive of a swinging mechanism.

[0039] With reference to Figure 3 , a side of the mounting frame 440 close to the weight bridge 100 is provided with a horizontally arranged U-shaped frame 422, and the water spraying nozzle 420 is installed in the U-shaped frame 422 through a vertical rotating shaft 423. The swinging mechanism is an electric motor 424, and the electric motor 424 is installed on a lower side of the U-shaped frame 422 and connected with the vertical rotating shaft 423.

[0040] When the license plate on the front side of the vehicle is being washed, the water spraying nozzle 420 can be controlled to ascend and descend by the lifting column 410, so that the height of the water spraying nozzle 420 is adapted to the height of the license plate on the front side of the vehicle, and meanwhile, the water spraying nozzle 420 can be driven to swing left and right by the motor 424, so as to ensure that the water spraying nozzle 420 can fully cover the license plate on the front side of the vehicle in the left and right directions during washing.

[0041] In some embodiments, referring to Figure 3 , the mounting frame 440 is provided with a lighting lamp 450 on the side facing the weighbridge 100, which can be turned on to irradiate the license plate on the front side of the vehicle at night or in the daytime with dim light, so as to ensure the light requirement of the license plate recognition camera 430 for license plate recognition.

[0042] In some embodiments, referring to Figure 3 , the mounting frame 440 is further provided with a distance sensor 460 on the side facing the weighbridge 100, which is used to detect the position of the head of the vehicle being weighed, and the distance sensor 460 can be an ultrasonic distance sensor, a laser distance sensor, an infrared distance sensor, etc.

[0043] Further comprising a reminding device, which is used to remind the driver after detecting that the head of the vehicle enters the set position.

[0044] When the vehicle drives onto the weighbridge 100, the distance between the head of the vehicle and the license plate cleaning and recognition mechanism 400 can be detected by the distance sensor 460, and the reminding device can remind the driver after the head of the vehicle enters the set distance range, so as to ensure that the vehicle is parked at the set position for license plate cleaning and recognition.

[0045] Optionally, the reminding device is provided with two, which are respectively located on the left side of the front and rear ends of the weighbridge 100, and the reminding device comprises a stand column supported on the ground and a traffic light 500 provided on the upper end of the stand column, and the traffic light 500 is provided with a voice prompt module.

[0046] When the vehicle reaches the set position, the traffic light 500 is red, and the voice prompt module prompts the driver to stop, and after the vehicle weighing and license plate recognition are completed, the traffic light 500 is green, and the voice prompt module prompts the driver to drive away.

[0047] In some embodiments, referring to Figure 3 , the mounting frame 440 is a vertically arranged flat plate, and the top of the mounting frame 440 is provided with a cover plate 441. The lifting column 410 is arranged on the side of the mounting frame 440 away from the weighbridge 100, and the upper end of the lifting column 410 is fixedly connected to the lower side of the cover plate 441. When the mounting frame 440 is retracted into the mounting groove 310 by the lifting column 410, the cover plate 441 is blocked at the slot of the mounting groove 310.

[0048] When the license plate cleaning and identifying mechanism 400 is retracted from the mounting groove 310 on the top of the weighbridge 300, the slot of the mounting groove 310 can be blocked by the cover plate 441, so as to protect the license plate cleaning and identifying mechanism 400 from pollution and damage from the outside.
