[0027] The invention is used as follows: It features a reasonable and simple structure, low production cost, and convenient installation. In use, the motor 6 is first started, driving the turntable 13 and cleaning bristles 14 to rotate via the transmission shaft 7. The rotation of the cleaning bristles 14 cleans the road surface. During dust suppression, water first enters the cavity 4 through the inlet pipe 8, then the water in the cavity 4 enters the annular cavity 10 through the outlet hole 9. The water in the annular cavity 10 then enters all the fixed pipes 11 and movable pipes 12. Finally, the water in the movable pipe 12 enters the interior of the hollow disc body 517 through the inlet hole 519. Water in the connecting pipe 516 is sprayed out through the nozzle 515 for dust suppression. The telescopic adjustment mechanism 2 installed here can adjust the extension distance of the movable pipe 12 and the nozzle 515 according to the amount of dust raised during sweeping, thereby meeting the dust suppression needs of the nozzle 515 at different ranges and improving the dust suppression effect during road sweeping. In specific telescopic adjustment, the motor 27 is first started to drive the drive gear 26 to rotate. The rotation of the drive gear 26 drives the transmission sleeve 29 to rotate through the transmission gear 28. The end face gear 25 drives all the screws 22 to rotate together. This rotation of the screws 22, in turn, causes all the movable tubes 12 to extend through the corresponding sliders 23, thus increasing the dust suppression range of all the nozzles 515 and improving the dust suppression effect during sweeping. The adjustable nozzle mechanism 5 allows for adjustment of the spray angle of the nozzles 515 as needed, meeting the requirements for spraying the space around the cleaning bristles 14 during ground spraying or rapid sweeping, thereby improving the dust suppression effect during sweeping. Specifically, when adjusting the angle, the motor is first started. The third gear 51 drives the second drive gear 52 to rotate, and the rotation of the second drive gear 52 drives the second end gear 55 to rotate through the second transmission gear 53 and the second transmission sleeve 54. The rotation of the second end gear 55 drives all the driven gears 56, the spline hole sleeve 57, the spline shaft 58 and the second screw 511 to rotate. The rotation of all the second screws 511 causes all the telescopic arms 513 to move synchronously, so that the connecting pipe 516 can be driven to rotate around the center of the hollow disc 517 through the connecting rod 514, which allows the nozzle 515 to face the ground or the space around the cleaning bristles 14.
