[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] like Figure 1-5As shown, a guardrail cleaning device for a cleaning vehicle includes a cleaning vehicle body and a robotic arm mounted on the cleaning vehicle body, and at least one pair of cleaning units mounted on the robotic arm. Each cleaning unit includes a mounting plate 1 fixedly connected to the end of the robotic arm, a hollow rotating tube 2 rotatably connected to the mounting plate 1, a sealing head mounted on the lower end of the rotating tube 2, a drive mechanism mounted on the mounting plate 1 for rotating the rotating tube 2, a rotary joint 3 mounted on the upper end of the rotating tube 2, and several cleaning mechanisms spaced along the axial direction of the rotating tube 2. At least one spacer ring 4 fitted and sleeved on the rotating tube 2 is provided between each two adjacent cleaning mechanisms, and at least one drain hole 5 communicating with the inside of the rotating tube 2 is provided through the spacer ring 4.

[0020] In the above technical solution, the cleaning vehicle body and the robotic arm are both existing mature technologies, which are not shown in the figure, and the specific structure and principle will not be described in detail in this article; When in use, the robotic arm drives a pair of cleaning units to move to both sides of the guardrail. The drive mechanism drives the rotating pipe 2 to rotate. The water pipe on the cleaning vehicle body is connected to the rotary joint 3. Water enters the rotating pipe 2 and then flows out through the drain hole 5 on the spacer ring 4, thereby wetting the cleaning mechanism. The rotation of the rotating pipe 2 drives several sets of cleaning mechanisms to scrub the guardrail. The rotation of the rotating tube 2 generates centrifugal force, which causes water to be thrown outwards, thus helping to remove dirt from the cleaning mechanism. This ensures that the contact parts between the cleaning mechanism and the guardrail remain clean. At the same time, the wet cleaning mechanism also helps to improve the cleaning of the guardrail, reducing water consumption and increasing the operating time. A nozzle can be installed on the drain hole 5, which can increase the impact force of the water flow, which is conducive to the removal of dirt from the cleaning mechanism, and can also further reduce water consumption; a splash guard is usually installed on the outside of the cleaning mechanism.

[0021] In a preferred embodiment of this utility model, a limiting ring 6 is fixedly sleeved on the rotating tube 2 near the mounting plate 1, and a mounting nut 7 that can abut against an adjacent cleaning mechanism is threaded onto the lower end of the rotating tube 2.

[0022] In the above technical solution, when it is necessary to replace the cleaning mechanism, loosen and remove the mounting nut 7, and several cleaning mechanisms and spacer rings 4 can be removed from the lower end of the rotating tube 2; then install the new cleaning mechanism and spacer rings 4 in the original order on the rotating tube 2, and then tighten the mounting nut 7.

[0023] In a preferred embodiment of the present invention, at least one strip-shaped groove 8 arranged in the same length direction is recessed on the outer surface of the rotating tube 2, and a first locking block 9 that matches the corresponding strip-shaped groove 8 is protruding on the inner wall of the spacer ring 4. The cleaning mechanism includes a mounting ring 10 sleeved on the rotating tube 2 and a plurality of cleaning strips 11 spaced along the circumferential direction of the mounting ring 10 and detachably assembled on the mounting ring 10. The inner wall of the mounting ring 10 is provided with a second locking block part 12 that matches the corresponding strip-shaped locking groove 8.

[0024] In the above technical solution, when replacing the cleaning mechanism, the cleaning strip 11 can be removed from the mounting ring 10 and the cleaning strip 11 on the mounting ring 10 can be replaced. The mounting ring 10 can be reused, reducing replacement costs. The first locking block 9 and the second locking block 12 can both be locked into the strip-shaped slot 8, so that the rotating tube 2 can drive the mounting ring 10 and the spacer ring 4 to rotate synchronously. The cleaning strip 11 is composed of several plastic strips.

[0025] In a preferred embodiment of this utility model, a water passage hole 13 corresponding to the spacer ring 4 is provided through the rotating pipe 2, and an annular groove 14 communicating with the corresponding water passage hole 13 is provided coaxially on the inner wall of the mounting ring 10. The annular groove 14 is connected to the drain hole 5.

[0026] In the above technical solution, when multiple drainage holes 5 are provided on the spacer ring 4, the water discharged from the water passage hole 13 can be transported to several drainage holes 5 through the annular groove 14.

[0027] In a preferred embodiment of the present invention, the rotary joint 3 is mounted on the rotary tube 2 via a mounting tube 15 coaxially connected to the rotary tube 2, and the driving mechanism includes a motor 16 mounted on a mounting plate 1 via a mounting bracket, a first gear 17 fixedly sleeved on the output shaft of the motor 16, and a second gear 18 fixedly sleeved on the mounting tube 15 and meshing with the first gear 17.

[0028] In a preferred embodiment of the present invention, a housing 19 sleeved on the outside of the second gear 18 is connected to the mounting bracket.

[0029] In a preferred embodiment of this utility model, the outer wall of the mounting ring 10 is provided with mounting slots 20 corresponding to a plurality of cleaning strips 11, the upper end of the mounting slots 20 is open, and the spacer ring 4 covers the upper end of the mounting slots 20.

[0030] In the above technical solution, the cleaning strip 11 is installed by inserting the end of the cleaning strip 11 into the mounting slot 20. Since the adjacent spacer ring 4 will block the mounting slot 20, the cleaning strip 11 will not fall off during use.

[0031] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
