When the cleaning reference frame 41 and the cleaning deflection frame 42 are adsorbed on each other, a ring-shaped cleaning pipeline is formed. When the ring-shaped cleaning pipeline needs to pass through the column 5 of the middle guardrail, the cleaning reference frame 41 and the cleaning deflection frame 42 are first separated from each other until the ring-shaped cleaning pipeline is The road is wrapped around the column 5, and then the road surface around the column 5 is cleaned, eliminating dead corners.

[0030] Specifically, the main cleaning vehicle 1 includes a cleaning frame 11, a cleaning power system 12, a cleaning system 13, a collection system 14, a collection bucket 15 and a dust cover 16.

The collection bucket 15 is installed on the cleaning frame 11. The collection bucket 15 is located on the side of the collection system 14. The cleaning power system 12 drives the collection system 14 to move and sweep the road garbage into the collection bucket 15. The dust cover 16 is installed on the cleaning frame 11. The dust cover 16 is located outside the cleaning system 13 and the collection system 14 to reduce dust leakage.

[0031] Specifically, two universal wheels 111 and two running wheels 112 are provided at the bottom of the cleaning frame 11 to enable the cleaning frame 11 to move. In order to facilitate walking, as a preferred embodiment, the cleaning frame 11 is also provided with a running motor that drives the running wheels 112 to rotate.

[0032] Specifically, the cleaning power system 12 includes a cleaning motor 121 and a reduction gearbox 122. The cleaning motor 121 is connected to the reduction gearbox 122 in transmission. A pulley is provided at the output end of the reduction gearbox 122. The cleaning system 13 and the collection system 14 are both connected to the pulley through a synchronous belt. The cleaning motor 121 simultaneously realizes the operation of the cleaning system 13 and the collection system 14.

[0033] Specifically, the cleaning system 13 includes a cleaning synchronization shaft 131, two cleaning transmission shafts 132 and two cleaning arms 133. The two cleaning arms 133 are rotatably mounted on the cleaning frame 11. A cylinder for controlling the opening and closing degree of the cleaning arms 133 is provided between the two cleaning arms 133 and the cleaning frame 11. The cleaning synchronization shaft 131 is rotatably mounted on the cleaning frame 11, and the two cleaning transmission shafts 132 are rotatably mounted on the cleaning frame 11. The axes of the two cleaning transmission shafts 132 are parallel to each other. The rotation axis of 2 is perpendicular to the rotation axis of the cleaning synchronization shaft 131. The two ends of the cleaning synchronization shaft 131 are respectively connected to the cleaning drive shaft 132 through bevel gear transmission. The two cleaning arms 133 are provided with a cleaning shaft 134. The two cleaning shafts 134 are respectively connected to the corresponding cleaning drive shaft 132 through a synchronous belt. The cleaning synchronization shaft 131 is connected to the cleaning power system 12 through a synchronous belt. The cleaning synchronization shaft 131 synchronously drives the two cleaning drive shafts 132 to rotate, thereby realizing the rotation of the two cleaning shafts 134 to achieve cleaning.

[0034] Specifically, the collection system 14 includes a collection wheel, the conveying direction of the lower side of the collection wheel points to the collection bucket 15, and the collection wheel is transmission-connected to the cleaning power system 12 to realize the rotation of the collection wheel and convey the dirt into the collection bucket 15.

[0035] Specifically, the cleaning reference frame 41 is slidably mounted on the main cleaning vehicle 1. Specifically, the cleaning reference frame 41 is provided with a guide mounting column 412 that slides with the main cleaning vehicle 1. A buffer spring is provided between the cleaning reference frame 41 and the main cleaning vehicle 1. The two ends of the buffer spring are respectively installed on the cleaning reference frame 41 and the main cleaning vehicle 1, so that the cleaning reference frame 41 has a fit when it cooperates with the column 5. The cleaning reference frame 41 is provided with an avoidance slope 411 on the inner part of each suction surface 45 located on the annular cleaning pipeline and the outer part of the suction surface 45 located on the annular cleaning pipeline. The avoidance slope 411 deflects in the direction away from the attraction surface 45. After the avoidance slope 411 contacts the column 5, under the guiding action of the avoidance slope 411, the cleaning reference frame 41 and the cleaning deflection frame 42 are opened at the attraction surface 45 position until the cleaning reference frame 41 and the cleaning deflection frame 42 are wrapped around the column 5, so that the cleaning reference frame 41 and the cleaning deflection frame 42 wrap around the column 5, and then clean the road surface under the column 5. Then the cleaning reference frame 41 and the cleaning deflection frame 42 are opened at the other attraction surface 45 position, so that the cleaning reference frame 41 and the cleaning deflection frame 42 are separated from the column 5.

[0036] The cleaning deflection frame 42 is provided with two water joints 422, each water joint 422 forms a conical surface, and the water joints 422 are connected to the cleaning pipeline on the cleaning reference frame 41. The water joints 422 realize the limit between the cleaning reference frame 41 and the cleaning deflection frame 42, so that the cleaning reference frame 41 and the cleaning deflection frame 42 will not shift relative to each other due to the different friction forces between the cleaning reference frame 41 and the cleaning deflection frame 42 and the column 5. After the suction surface 45 of the cleaning reference frame 41 and the cleaning deflection frame 42 is opened, the cleaning deflection frame 42 rotates around the cleaning reference frame 41 under the restriction of the water joints 42. In order to further prevent the cleaning reference frame 41 and the cleaning deflection frame 42 from shifting relative to each other, the cleaning deflection frame 42 is also provided with an auxiliary limiting conical surface 423, which serves as a reference for the rotation of the cleaning deflection frame 42 when the cleaning reference frame 41 and the cleaning deflection frame 42 are opened.

[0037] In order to ensure that the cleaning reference frame 41 and the cleaning deflection frame 42 can be closed again after opening each other, permanent magnets are provided on the avoidance slope 411 and the escape slope 421, so that the avoidance slope 411 and the escape slope 421 can attract the guardrail column 5 when the cleaning reference frame 41 and the cleaning deflection frame 42 are separated from each other, ensuring that the cleaning reference frame 41 and the cleaning deflection frame 42 can be closed smoothly after opening.

[0038] When the cleaning frame 11 is moving, the cleaning reference frame 41 can supply water all the time, but continuous water supply may cause water splashing. If the road surface does not allow water splashing because it needs to ensure the passage of pedestrians, water can be supplied for cleaning after the cleaning reference frame 41 and the cleaning deflection frame 42 are covered with the column 5. In order to reduce water leakage, a sealing ring is provided at the matching position of the cleaning reference frame 41 and the water joint 422.
