Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1 and Figure 2 An embodiment of the present invention provides a highway guardrail cleaning device, including a movable plate 1, a support rod 3 is provided on the right side of the upper surface of the movable plate 1, a movable sleeve 4 is sleeved on the outside of the support rod 3, and a cleaning frame 7 is installed on the left side of the movable sleeve 4 through a disassembly and assembly assembly. Two sets of cleaning rollers 16 are provided on the lower side inside the cleaning frame 7, and a cleaning brush 20 is provided on the outside of the cleaning rollers 16. Specifically, the device moves smoothly along the guardrail via a movable plate 1, with a support rod 3 providing stable support for the movable plate 1. The movable sleeve 4 slides on the support rod 3 to adjust the cleaning frame 7 along the guardrail position, achieving precise alignment of the cleaning position. Two sets of cleaning rollers 16, located on the lower side inside the cleaning frame 7, work in conjunction with the cleaning brushes 20 on the outside during the device's movement to efficiently scrub the guardrail, thereby achieving the effect of removing dust, dirt, and debris.

[0020] Reference Figure 4 and Figure 5The assembly and disassembly assembly includes two sets of mounting frames 8, which are fixedly installed on the left side of the movable sleeve 4. Two sets of mounting blocks 9 are provided on the right side of the cleaning frame 7. Two sets of limiting blocks are provided in the middle of the interior of the mounting frame 8. Adjusting rods 10 are movably inserted into the front side of both sets of mounting frames 8. Fixing blocks 11 are provided at the rear end of each adjusting rod 10. A matching fixing groove is provided on the front side of the mounting block 9. Return springs 12 are provided on the outer side of both sets of adjusting rods 10. The two ends of the two sets of return springs 12 are respectively connected to the front side of the interior of the mounting frame 8 and the front side of the fixing block 11. Adjusting plates 13 are provided at the front end of both sets of adjusting rods 10. Specifically, by pulling the adjusting plate 13, the two sets of fixing blocks 11 are moved, and then the mounting block 9 is inserted into the mounting frame 8. Then, the adjusting plate 13 is released, and the return spring 12 moves the two sets of fixing blocks 11, thereby inserting the two sets of fixing blocks 11 into the fixing slots opened on the front side of the two sets of mounting blocks 9 to fix the mounting blocks 9, so as to realize the quick assembly and disassembly of the cleaning frame 7. When it is necessary to remove it, by pulling the adjusting plate 13, the fixing blocks 11 are disengaged from the fixing slots opened on the mounting blocks 9, releasing the fixing of the mounting blocks 9 and facilitating the removal of the cleaning frame 7.

[0021] Reference Figure 1 Each of the four corners of the lower surface of the movable plate 1 is equipped with a movable wheel 2; Specifically, the movable wheel 2 can significantly improve the smooth movement and flexibility of the device along the guardrail. The arrangement of the four corner wheels can evenly distribute the weight of the device itself, reduce the local pressure on the movable plate 1 and the guardrail, and at the same time ensure the stability of the device when it is in a straight line or turning, preventing tilting or jamming.

[0022] Reference Figure 3 The movable sleeve 4 has an adjusting gear 5 rotatably installed inside, and the support rod 3 has a matching tooth groove on the left side inside, and a drive motor 6 is installed on the front side of the adjusting gear 5. Specifically, by turning on the drive motor 6, the adjusting gear 5 is driven to rotate inside the support rod 3. Then, by adjusting the engagement of the gear 5 with the tooth groove, the moving frame is driven to move outside the support rod 3. This allows the cleaning frame 7 to flexibly adjust its position according to the different heights, curves, or spacing of the guardrail, thereby improving the fit between the cleaning roller 16 and the cleaning brush 20 and the surface of the guardrail, thus ensuring uniform and efficient cleaning.

[0023] Reference Figure 6 The cleaning frame 7 has three sets of rotating frames 14 on both the upper and lower sides, and each of the six sets of rotating frames 14 has a roller 15 inside. Specifically, the roller 15 and the rotating frame 14 work together to form a multi-point bearing and guide, so that the cleaning frame 7 can move smoothly and avoid uneven contact between the cleaning roller 16 and the cleaning brush 20 and the guardrail due to friction or deviation, thus ensuring a continuous and uniform cleaning process.

[0024] Reference Figure 6 Both sets of cleaning rollers 16 are equipped with rotating disks 17 on their upper sides, and two sets of rotating motors 18 are provided on the right side of the cleaning frame 7. The left ends of the two sets of rotating motors 18 are equipped with bevel gears 19, and the outer sides of the upper surfaces of the two sets of rotating disks 17 are provided with tooth grooves that match the bevel gears 19. Multiple sets of water spray holes 21 are provided on the surfaces of the two sets of cleaning rollers 16, and water pipes 22 are connected to the upper ends of the two sets of cleaning rollers 16. Specifically, the rotating disk 17 on the upper side of the two sets of cleaning rollers 16 is driven by the bevel gears 19 of the two sets of rotating motors 18 on the right side of the cleaning frame 7. With the tooth grooves on the upper surface of the rotating disk 17, the cleaning rollers 16 are rotated synchronously and stably. Multiple sets of water spray holes 21 on the surface of the two sets of cleaning rollers 16 are supplied with water through the water supply pipe 22 connected at the upper end. This allows the cleaning brush 20 to continuously wet and rinse the surface of the guardrail while rotating, improving the brushing efficiency. At the same time, the combination of wetting and rinsing through water spraying can effectively remove dust, dirt and stubborn debris from the guardrail.

[0025] Working principle: The cleaning frame 7 is installed on the left side of the movable sleeve 4 by disassembling and assembling the components. Then, the drive motor 6 is turned on, which drives the adjusting gear 5 to rotate. Then, by adjusting the gear 5 and the tooth groove, the movable frame is adjusted to a suitable height. The movable plate 1 is moved to a suitable position by the movable wheel 2, and the cleaning frame 7 is placed on the outside of the guardrail. Then, the rotating motor 18 is turned on, which drives the two sets of cleaning rollers 16 inside the cleaning frame 7 to rotate and brush the guardrail surface in conjunction with the outer cleaning brush 20. The upper rotating disk 17 is synchronously driven by the rotating motor 18 and the bevel gear 19. At the same time, multiple sets of water spray holes 21 and water supply pipes 22 continuously supply water, realizing the combination of brushing and rinsing, so as to efficiently and evenly remove dust, dirt and debris from the surface of the guardrail.
