[0030] See also Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The telescopic reset assembly 4 includes a limiting cylinder 41 fixedly arranged on the support frame 2, and the limiting cylinder 41 is arranged horizontally; a guide ball 46 is arranged inside the limiting cylinder 41, and the guide ball 46 is adapted to the limiting cylinder 41; the guide ball 46 and the end of the wing 52 away from the middle part 51 are connected with a metal rod 43, and the metal rod 43 corresponds to the center position of the guide ball 46; the guide ball 46 can be a steel ball, and the material of the limiting cylinder 41 is also steel, and the outer wall of the guide ball 46 is smoothed; a retaining ring 42 is fixed inside the limiting cylinder 41, and the metal rod 43 passes through the retaining ring 42.

[0031] The telescopic reset assembly 4 also includes a mounting tube 45, which is embedded in the support seat body 1; the mounting tube 45 is coaxial with the limiting tube 41, and a telescopic spring 44 is installed on the mounting tube 45, and the end of the telescopic spring 44 away from the inner wall of the mounting tube 45 is connected to the guide ball 46; in addition, a stopper 47 is also arranged in the limiting tube 41, and the stopper 47 is used to prevent the guide ball 46 from moving out from the end of the limiting tube 41 away from the retaining ring 42.

[0032] See also Figure 1 and Figure 6 The brush assembly 7 includes a connecting strip 72, which is fixedly arranged on the support belt 5. The support belt 5 and the connecting strip 72 are relatively thin and can be made of nylon, so that the support belt 5 and the connecting strip 72 have good flexibility; a strip brush 71 is fixedly arranged on the connecting strip 72, and the part of the strip brush 71 used to fix the bristles is made of flexible material, such as rubber, silicone, etc., and the bristles of the strip brush 71 can be made of nylon.

[0033] See also Figure 1 and Figure 7 A support plate 8 is fixedly connected to the support seat body 1, and a connecting portion 81 is provided on the support plate 8, and a mounting hole 811 is provided on the connecting portion 81; the installation of the support plate 8 is facilitated by the connecting portion 81. Specifically, the support plate 8 can be movably arranged on the sanitation vehicle so that the support plate 8 can move up and down. In addition, a lifting device (such as a hydraulic cylinder or a connecting rod driving device, etc.) can be installed on the sanitation vehicle. The lifting device is used to drive the support plate 8 to move up and down. This is a prior art and will not be repeated here; through the above-mentioned arrangement, the position of the support plate 8 can be adjusted, thereby realizing the adjustment of the position of the support belt 5.

[0034] See also Figure 1-Figure 8In the present embodiment, when the airflow is sprayed toward the middle part 51 through the injection pipe 62, since the metal rod 43 is connected between the wing 52 and the guide ball 46, and the telescopic spring 44 is connected to the guide ball 46, the middle part 51 can move in the direction away from the airflow injection assembly 6 under the direct blowing of the high-pressure airflow, and the middle part 51 drives the wing 52 to move, and the wing 52 drives the metal rod 43 to move, thereby driving the guide ball 46 to move in the limit tube 41, and stretching the telescopic spring 44; when the guide ball 46 contacts the retaining ring 42, the retaining ring 42 blocks the movement of the guide ball 46, and at this time the middle part 51 stops moving in the direction away from the airflow injection assembly 6; since the first guide roller 31, the second guide roller 32, the first protrusion 33 and the second protrusion 34 are provided, the wing 52 is guided and limited during the movement of the support belt 5, which helps to ensure that the upper and lower end surfaces of the support belt 5 remain in a horizontal state; and when the injection pipe 62 stops spraying the airflow, the telescopic spring 44 is reset, thereby realizing the reset of the support belt 5.

[0035] When cleaning the road guardrail, after adjusting the support plate 8 to a suitable position, a high-pressure airflow is sprayed toward the middle part 51 through the injection pipe 62, so that the support belt 5 moves away from the injection pipe 62, and further drives the metal rod 43 and the guide ball 46 to move. When the guide ball 46 contacts the retaining ring 42, the support belt 5 no longer continues to move away from the injection pipe 62; thereafter, the strip brush 71 on the support belt 5 is driven by the sanitation vehicle to contact and squeeze the guardrail; the road guardrail is composed of multiple rods of different thicknesses, that is, the shape of the road guardrail is not regular; since the support belt 5 can be bent and deformed, the strip brush 71 on the support belt 5 can better fit the surface of the road guardrail when the sanitation vehicle is driving along the length direction of the road guardrail, thereby improving the sweeping effect of the road guardrail, and thus improving the cleaning effect of the road guardrail.

[0036] Embodiment 2 See also Figure 1 , Figure 2 as well as Figure 8 This embodiment is based on the first embodiment, and a plurality of pore groups 53 are provided on each middle portion 51, and the plurality of pore groups 53 on the middle portion 51 are respectively located between two adjacent brush assemblies 7 on the middle portion 51; Figure 8 As shown, the air hole group 53 is composed of a plurality of exhaust holes 531, and the plurality of exhaust holes 531 are arranged at intervals; when the road guardrail is cleaned, after the airflow injection assembly 6 injects airflow to the middle portion 51, a portion of the airflow can be discharged through the exhaust holes 531, so as to sweep away the dust or impurities on the road guardrail, thereby further improving the cleaning effect of the road guardrail; the diameter of the exhaust hole 531 is much smaller than the overall length of the strip brush 71, and does not affect the airflow injection assembly 6 to inject airflow to prompt the support belt 5 to move.

[0037] Embodiment 3 See also Figure 4 , Figure 5 as well as Fig. 9 This embodiment is based on the first embodiment. In this embodiment, the installation method of the retaining ring 42 is replaced, that is, the fixing method of the retaining ring 42 is replaced by a threaded matching method, and the retaining ring 42 is threadedly connected with the limiting cylinder 41; specifically, the limiting cylinder 41 and the retaining ring 42 are both provided with a threaded structure, and the limiting cylinder 41 is sleeved on the outside of the retaining ring 42, that is, by rotating the retaining ring 42, the position of the retaining ring 42 can be adjusted.

[0038] By synchronously adjusting the position of each retaining ring 42, that is, synchronously adjusting the length of each retaining ring 42 inside the limiting cylinder 41, the maximum displacement of the support belt 5 moving away from the injection pipe 62 can be changed; the greater the maximum displacement of the support belt 5 moving away from the injection pipe 62, the farther the sanitation vehicle can be away from the road guardrail during the cleaning process, and the farther the sanitation vehicle is away from the road guardrail, the lower the risk of the sanitation vehicle colliding with the road guardrail; that is, the sanitation vehicle can adjust the maximum displacement of the support belt 5 moving away from the injection pipe 62 according to road conditions of different widths, which can not only ensure that the sanitation vehicle can effectively clean the road guardrail under different road conditions, but also reduce safety hazards, while improving the adaptability of the entire device.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
