[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment As Figure 1-7 shown, a highway high-pressure cleaning device proposed in an embodiment of the present invention includes a mobile device 1. A mixing structure 2, a flushing structure 3 and a dust suction structure 4 are arranged inside the mobile device 1, and the mixing structure 2 is communicated with the flushing structure 3.

[0022] The mixing structure 2 includes a mixing barrel 201. A top cover 202 is movably clamped at the top end of the mixing barrel 201. An external motor 203 is fixedly installed at the top end of the top cover 202. The output shaft of the external motor 203 penetrates through the top cover 202 and extends to the inside of the mixing barrel 201 and is fixedly connected with a stirring shaft 204.

[0023] The flushing structure 3 includes an installation table 301. A road sign cleaning structure 302 is arranged at the top end of the installation table 301, and a ground cleaning structure 303 is arranged at the bottom end of the installation table 301.

[0024] The dust suction structure 4 includes a vacuum cleaner 401. A dust suction pipe 402 is installed at the bottom end of the vacuum cleaner 401. A connecting pipe 403 is fixedly installed on the back side of the vacuum cleaner 401. The other end of the connecting pipe 403 is installed with a dust collection box 404. A recycling box 405 is movably inserted into the inner side of the dust collection box 404.

[0025] As Figure 2 shown, in some embodiments, the moving device 1 includes a moving base 101. A guardrail 102 is provided at the edge of the moving base 101. A push handle 103 is fixedly installed on the back side of the moving base 101. A docking rod 106 is hinged to the front side of the moving base 101.

[0026] Specifically, the docking rod 106 can be used to connect the device to a towing device, and the device is dragged by the towing device to move, realizing a wide - range coverage of the road cleaning operation. At the same time, the setting of the guardrail 102 not only enhances the safety of the operator, but also effectively prevents water from splashing during the cleaning process, keeping the working environment clean.

[0027] As Figure 2 shown, in some embodiments, a positioning hole 104 is opened inside the moving base 101. The mixing barrel 201 is located inside the positioning hole 104. An installation opening 105 is opened inside the moving base 101. The installation table 301 is located inside the installation opening 105. A connection port is opened inside the moving base 101. The vacuum cleaner 401 is located inside the connection port.

[0028] Specifically, the settings of the positioning hole 104, the installation opening 105 and the connection port not only provide a stable installation position for the mixing structure 2, the flushing structure 3 and the dust suction structure 4, but also ensure the orderly arrangement of each component inside the moving device 1. Such a design not only optimizes the internal structure of the device, but also improves the stability and reliability of the overall device.

[0029] The mixing barrel 201 is stably installed on the moving base 101 through the positioning hole 104. Such an installation method not only ensures the stability of the mixing barrel 201 during the cleaning operation, but also facilitates the operator to maintain and replace the mixing barrel 201. At the same time, the design of the installation opening 105 enables the flushing structure 3 to be conveniently installed on the moving device 1 and is connected to the liquid outlet pipe 207 of the mixing barrel 201 through a connecting hose, thus ensuring the smooth transmission of the cleaning solution.

[0030] As Figure 3 shown, in some embodiments, a mixing blade 205 is fixedly sleeved on the outer side of the stirring shaft 204. The mixing blade 205 is in a spiral - rising shape.

[0031] Specifically, the spiral design of the mixing blade 205 can more effectively promote the circulating flow of the mixture of the cleaner and water in the mixing barrel 201. When the external motor 203 is started and the stirring shaft 204 drives the mixing blade 205 to rotate, the spiral mixing blade 205 can not only stir the mixture in the horizontal direction, but also generate an upward thrust in the vertical direction, causing the mixture to form an up-and-down circulating flow pattern in the mixing barrel 201. This flow pattern ensures that the cleaner can be more evenly distributed in the water, improving the mixing efficiency and uniformity, and thus ensuring the cleaning effect of the cleaning solution.

[0032] In addition, the material selection of the mixing blade 205 is also crucial. To enhance its wear resistance and corrosion resistance, the mixing blade 205 is usually made of stainless steel or high-strength plastic. These materials can not only withstand the frictional force and impact force generated during the stirring process, but also effectively resist the chemical corrosion of the cleaner, extending the service life of the mixing blade 205 and reducing the maintenance cost.

[0033] As Figure 3 shown, in some embodiments, a liquid inlet pipe 206 is fixedly installed on the back side of the mixing barrel 201, and two liquid outlet pipes 207 are installed on the front side of the mixing barrel 201. The two liquid outlet pipes 207 are respectively connected to the road sign cleaning structure 302 and the ground cleaning structure 303 through connecting hoses.

[0034] Specifically, the setting of the liquid inlet pipe 206 and the liquid outlet pipes 207 enables the mixed cleaning solution to flow smoothly to the road sign cleaning structure 302 and the ground cleaning structure 303, ensuring the continuous progress of the cleaning operation. At the same time, this design also facilitates the operator to adjust the flow rate of the cleaning solution according to needs during the cleaning process, further improving the flexibility and efficiency of the cleaning operation.

[0035] As Figure 5 shown, in some embodiments, the road sign cleaning structure 302 includes a braking motor 304, a turntable 305 and a follower wheel 306. The bottom end of the braking motor 304 is fixedly connected to the top end of the mounting table 301. The turntable 305 and the follower wheel 306 are both rotatably connected to the top end of the mounting table 301. The braking motor 304 and the follower wheel 306 are connected by a transmission chain. A rack 308 is fixedly connected to the center of the back side of the follower wheel 306, and a toothed ring 307 is fixedly sleeved on the outer side of the turntable 305. The rack 308 meshes with the toothed ring 307.

[0036] Specifically, when the braking motor 304 is started, its power is transmitted to the follower wheel 306 through the transmission chain, and then drives the rack 308 to rotate. Since the rack 308 meshes with the toothed ring 307 on the outer side of the turntable 305, the rotation of the rack 308 will cause the toothed ring 307 to drive the turntable 305 to rotate.

[0037] This structural design not only achieves precise angle adjustment but also ensures the stability and reliability of the transmission. The rotation of the turntable 305 further drives the first high-pressure nozzle 312 mounted on it to adjust the angle, enabling the high-pressure water flow to accurately spray onto the road signs or other objects that need to be cleaned.

[0038] As Figure 5 shown, in some embodiments, an installation box 309 is fixedly installed at the top of the turntable 305. An electric telescopic rod 310 is installed on the inner wall of the installation box 309. The movable end of the electric telescopic rod 310 extends to the outside of the installation box 309 and is equipped with a tripod 311. The front side of the tripod 311 is fixedly connected to the first high-pressure nozzle 312.

[0039] Specifically, the telescopic function of the electric telescopic rod 310 enables the tripod 311 and the first high-pressure nozzle 312 to adjust the height in the vertical direction. This flexibility in height adjustment ensures that the first high-pressure nozzle 312 can perform precise cleaning operations on road signs or other cleaning targets at different heights. At the same time, the design of the tripod 311 not only enhances the stability of the first high-pressure nozzle 312 but also helps to evenly distribute the impact force of the high-pressure water flow, improving the cleaning effect.

[0040] To enhance the flexibility and efficiency of the cleaning operation, the first high-pressure nozzle 312 can also be equipped with various different nozzle types, such as fan nozzles, conical nozzles, etc., to meet the requirements of different cleaning scenarios. The operator can select the appropriate nozzle type according to actual needs and achieve precise cleaning of the cleaning target by adjusting the spraying angle and height of the first high-pressure nozzle 312.

[0041] As Figure 6 shown, in some embodiments, the ground cleaning structure 303 includes a first mounting frame 313, a second mounting frame 314, and a third mounting frame 315. The top of the first mounting frame 313 is movably connected to the bottom of the mounting table 301 through an electric push rod 316. The tops of the second mounting frame 314 and the third mounting frame 315 are both fixedly connected to the bottom of the mounting table 301.

[0042] Specifically, the telescopic function of the electric push rod 316 enables the first mounting frame 313 to adjust the height in the vertical direction, thereby driving the cleaning brush roller 317 to adapt to the cleaning requirements of different ground heights. This design not only enhances the flexibility of ground cleaning but also ensures that the cleaning operation can cover every corner of the ground, improving the cleaning efficiency and effect.

[0043] As Figure 6As shown, the second mounting bracket 314 is located on the front side of the third mounting bracket 315, and the second mounting bracket 314 and the third mounting bracket 315 are arranged vertically.

[0044] Specifically, this vertical arrangement design of the second mounting bracket 314 and the third mounting bracket 315 enables the second high-pressure nozzle 318 and the third high-pressure nozzle 319 to form a cross-flushing effect, further enhancing the comprehensiveness and thoroughness of ground cleaning. When high-pressure water jets are ejected from these two nozzles, they can complement each other to ensure no omission in cleaning, especially for cleaning the gaps and depressions on the road surface, and the cleaning effect is particularly remarkable.

[0045] The drive motor 320 can drive the second high-pressure nozzle 318 and the third high-pressure nozzle 319 to swing slightly, thereby increasing the flushing coverage and uniformity. This design not only improves the cleaning efficiency but also makes the cleaning operation more meticulous, ensuring the improvement of cleaning quality.

[0046] During use, the operator first adds an appropriate amount of detergent and clean water into the mixing barrel 201 through the liquid inlet pipe 206, and then starts the external motor 203. The external motor 203 drives the stirring shaft 204 and the mixing blades 205 to rotate, fully mixing the detergent and clean water. The mixed cleaning solution flows through the liquid outlet pipe 207 to the road sign cleaning structure 302 and the ground cleaning structure 303 respectively.

[0047] When it is necessary to clean the road signs along the road, the operator starts the braking motor 304. The braking motor 304 drives the follower wheel 306 and the rack 308 to rotate through the transmission chain, and then prompts the toothed ring 307 to drive the turntable 305 to rotate. The rotation of the turntable 305 enables the first high-pressure nozzle 312 installed thereon to adjust the angle, and at the same time, the electric telescopic rod 310 expands and contracts to adjust the height of the first high-pressure nozzle 312.

[0048] The operator precisely adjusts the spraying angle and height of the first high-pressure nozzle 312 according to the height and position of the road sign, then opens the liquid outlet pipe 207, and the liquid outlet pipe 207 sprays out from the first high-pressure nozzle 312 to conduct fixed-point cleaning on the road sign. After the cleaning is completed, the operator closes the liquid outlet pipe 207 and resets the first high-pressure nozzle 312 by adjusting the braking motor 304 and the electric telescopic rod 310.

[0049] When cleaning the ground, the operator starts the electric push rod 316 and the drive motor 320. The electric push rod 316 expands and contracts to adjust the height of the first mounting bracket 313 and the cleaning brush 317 to adapt to the cleaning requirements of different ground heights, and then starts the drive motor 320 outside the first mounting bracket 313 to make the cleaning brush 317 start to rotate; Meanwhile, the drive motor 320 drives the second high-pressure nozzle 318 and the third high-pressure nozzle 319 to swing slightly, increasing the coverage area and uniformity of the flushing. High-pressure water jets are ejected from these two nozzles, forming a cross-flushing effect to flush the ground in all directions.

[0050] During the flushing process, the dust suction structure 4 is activated simultaneously. The vacuum cleaner 401 sucks the stains and accumulated water on the ground into the recycling box 405 in the dust collection box 404 through the suction pipe 402, keeping the ground clean and tidy. Moreover, the recycling box 405 can be replaced to prevent the deterioration of the dust suction effect due to the overfilling of the recycling box 405.

[0051] In summary, by using the braking motor 304 to drive the rack 308 to push the gear ring 307, and then driving the first high-pressure nozzle 312 on the turntable 305 to perform precise angle adjustment. The nozzle can be flexibly adjusted to the required angle to meet different cleaning needs. In addition, with the cooperation of the electric telescopic rod 310, the height adjustment of the first high-pressure nozzle 312 is realized, enabling the first high-pressure nozzle 312 to perform fixed-point cleaning on the billboards along the road, the advertising leaflets pasted on the roadside, and other objects that need to be cleaned according to actual requirements. In this way, the cleaning operation becomes not only more flexible but also more accurate in targeting specific areas, improving the cleaning efficiency and effect, making the cleaning work more efficient and convenient, and at the same time ensuring the improvement of the cleaning quality; Through the ground cleaning structure 303, using the cleaning brush roller 317 on the first mounting bracket 313, the ground can be physically cleaned deeply to effectively remove stubborn stains and attachments. At the same time, the second high-pressure nozzle 318 and the third high-pressure nozzle 319 on the second mounting bracket 314 and the third mounting bracket 315 can eject high-pressure water jets to flush the ground in all directions, ensuring no dead corners in the cleaning. This ground cleaning structure 303 that combines physical cleaning and high-pressure water flushing improves the cleanliness and cleaning efficiency of the ground. In addition, the design of the second mounting bracket 314 and the third mounting bracket 315 arranged vertically can flush the washed stains to the roadside through the sewage discharge component, thus ensuring the cleanliness of the road surface, enabling the high-pressure nozzles to cover a wider area, and further improving the cleaning effect.

[0052] It should be noted that the specific model specifications of the external motor 203, braking motor 304, electric telescopic rod 310, electric push rod 316, and drive motor 320 in this highway high-pressure cleaning device need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0053] Moreover, the power supply and its principle of the external motor 203, braking motor 304, electric telescopic rod 310, electric push rod 316, and drive motor 320 in the highway high-pressure cleaning device are clear to those skilled in the art and will not be described in detail herein.

[0054] Moreover, the working principles and wiring methods of the external motor 203, braking motor 304, electric telescopic rod 310, electric push rod 316, and drive motor 320 in the highway high-pressure cleaning device are common knowledge, and they all belong to conventional means or well-known common sense. Therefore, they will not be elaborated herein. Those skilled in the art can make any selection according to their needs or convenience.
