[0019] Unless otherwise specified, the scientific and technical terms used in this article are intended for understanding by those skilled in the art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1 As shown, the road marking cleaning device of this utility model includes a mobile platform 1. The mobile platform is equipped with a heating device, a cleaning device, and a dust extraction device. The heat outlet 13 of the heating device, the cleaning component 20 of the cleaning device, and the dust extraction port 14 of the dust extraction device are close to the ground and located on the same straight line, along the moving direction of the mobile platform during operation. Figure 1 (As indicated by the arrow), the dust extraction port of the dust collector, the cleaning components of the cleaning device, and the heat outlet of the heating device are arranged in sequence.

[0022] When the device is in operation, it moves along the road markings to be cleaned. The heating device first heats and softens the markings through its heat outlet near the ground. Then, the cleaning component of the cleaning device peels off the softened marking material, and finally, the dust collector removes the peeled marking material. In some designs, the road marking cleaning device of this utility model is equipped with a main switch and three branch switches. The main switch controls the simultaneous opening and closing of the dust collector, cleaning device, and heating device; the three branch switches control the independent opening and closing of each device (the relevant electrical connections can use existing switch control circuits). This expands the device's functionality; when there is a large amount of dust on the ground, manual pre-cleaning is unnecessary. The dust collector can be turned on first to remove the dust before starting the heating and cleaning devices to clean the markings.

[0023] In the specific scheme, the width of the heat outlet of the heating device (i.e., the dimension in the vertical direction along the moving direction of the moving platform) is equal to or slightly larger than the width of the marking to be cleaned. The width of the cleaning component and the dust extraction port is equal to or slightly larger than the width of the heat outlet. Preferably, the width of the dust extraction port is slightly larger than the width of the cleaning component, and the width of the cleaning component is slightly larger than the width of the heat outlet, so as to ensure that the marking is thoroughly cleaned.

[0024] In some specific solutions, the heating device can be either a hot air heating device or a microwave heating device. When using a hot air heating device, hot air is ejected from its heat outlet to heat the marking material; specifically, hot air can be generated by heating air with electrical energy. See [link to microwave heating device] for details. Figure 1 As shown, its related components include a microwave generator 7, a circulator 8, an automatic impedance matching device 9, a bend waveguide 10, and a microwave focusing antenna 13. The microwave generator 7, circulator 8, and automatic impedance matching device 9 are connected sequentially and mounted on a mobile platform. The microwave antenna 13, serving as the microwave outlet (i.e., heat or energy outlet), is located at the front end of the mobile platform. The automatic impedance matching device 9 is connected to the microwave antenna 13 via the bend waveguide 10. During operation, the microwave generator 7 generates continuous or pulse signals within the microwave frequency band. The circulator 8 is connected to the microwave generator via a standard rectangular waveguide flange and acts as an isolator to protect the microwave generator from microwaves reflected back from the load. The reflected microwave power is measured by a built-in microwave power meter and absorbed by the water load. The automatic impedance matching device 9 is connected to the circulator via a standard rectangular waveguide flange. Its main function is to achieve impedance matching between the microwave source and the rock load, thereby maximizing microwave power transmission efficiency. Automatic or manual pin-type tuners can be selected. The automatic impedance matching device 9 is connected to the microwave focusing antenna 13 via the bend waveguide 10 for outputting the generated heating microwaves. In the preferred embodiment, the microwave generator 7, the circulator 8, and the automatic impedance matching device 9 are covered with a shielding cover 6.

[0025] In a specific design, the cleaning device can be a cleaning shovel or a cleaning brush, with the cleaning components being either a cleaning blade or a cleaning brush. Figure 1 The cleaning shovel 20 shown is driven by a first motor 112, which is installed at a suitable position on the moving platform. Figure 1 and 2 The first motor shown is mounted on the mounting plate 19 located at the front end of the mobile platform and above the cleaning shovel.

[0026] In the specific design, the dust collector uses a conventional dust extraction device, which generally includes a dust collection box 17, a drive motor 111, a dust pump 15, and a dust extraction pipeline 12, with the dust extraction port 14 on the pipeline facing the ground. For example... Figure 1 and 2As shown, the dust collecting box 17 is arranged on the moving platform, the dust extraction pump and the driving motor are arranged on the mounting plate 19 at the front end of the moving platform and above the dust extraction pipeline.

[0027] In specific solutions, the moving platform needs to meet the requirements of the line cleaning and the bearing of the working components. A specific moving platform is as shown in the figure. Figure 1 As shown, the body is a flat placing table, a handrail 2 is welded at one end of the flat placing table, a rubber sleeve 3 is sleeved on the handrail, the car body can be conveniently pushed, the dust extraction port, the cleaning component and the heat outlet are located at the other end, and four universal wheels 16 are arranged at the bottom of the flat placing table. In a further preferred solution, the horizontal end of the handrail 2 is provided with a general switch 18 and three separate switches (not shown in the figure) to control the overall switch work of the device and the independent work of each functional device.

[0028] In some solutions, the cleaning device further comprises a storage battery 5, which is arranged at a reasonable position of the moving platform to supply power to the heating device, the dust extraction machine and the cleaning device. As shown, Figure 1 The storage battery is arranged at a position close to the end of the moving platform, and a protective cover 4 (with heat dissipation holes) is further arranged on the storage battery 5 to protect the storage battery 5.

[0029] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still combine the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features.
