For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following describes a road maintenance and cleaning device according to an embodiment of the present invention with reference to the accompanying drawings.

[0025] Referring to Figures 1 to 4 , a road maintenance and cleaning device according to an embodiment of the present invention includes a moving frame 1, a suction module, a flushing module, and a blowing module. The moving frame 1 can provide an installation platform for other components of the road maintenance and cleaning device and move to the destination together. The moving frame 1 can be pulled or pushed by a worker or pulled by other power equipment, such as a tractor, to move.

[0026] The suction module includes a suction hood, a first intake passage 2, a suction fan 3, a first exhaust passage 4, and a collector 5. The suction hood can locally isolate the shrouded central median section from the outside.

[0027] Specifically, referring to Figure 3 、 Figure 4 , the suction hood includes a moving support, a PVC tarpaulin 6, and a suction pipe 7. The moving support can span across the central median and can move along the extension direction of the central median. The moving support includes a number of sub-supports 8 arranged in sequence in a "冂" shape. Each sub-support 8 can span across the central median at the same time, and its bottom end of the foot is provided with a traveling wheel 9. The distance between each moving support is fixed. For example, adjacent sub-supports 8 are fixedly connected by a cross-link 10 with a fixed length, or it can be telescopic. For example, adjacent sub-supports 8 are connected by a cross-link 10 with an adjustable length.

[0028] The PVC tarpaulin 6 covers the moving support to enclose the left side, right side, and top of the moving support. The PVC tarpaulin 6 has good sealing performance and strong flexibility.

[0029] The suction pipe 7 is fixed to the inner side of the sub-bracket 8 located in the middle. If the number of sub-brackets 8 is even, the suction pipe 7 is fixed to one of the two middle sub-brackets 8. The suction pipe 7 is generally in a "冂" shape and includes a first pipe 11, a second pipe 12, and a third pipe 13. The first pipe 11 and the second pipe 12 are respectively fixed to the two leg parts of the sub-bracket 8, and the third pipe 13 is fixed to the top connection part of the sub-bracket 8. The two ends of the third pipe 13 are respectively communicated with the upper ends of the first pipe 11 and the second pipe 12. The first air inlet channel 2 is communicated with the middle part of the third pipe 13. The first pipe 11, the second pipe 12, and the third pipe 13 are all provided with air inlets 14. The exhaust fan 3 and the collector 5 are arranged on the moving frame 1. When the exhaust fan 3 works, it can create a negative pressure in the area covered by the suction hood. The sundries in this area can enter the collector 5 in sequence through the air inlets 14, the suction pipe 7, the first air inlet pipe, and the first exhaust channel 4. The collector 5 can be a trash can, a garbage bag, etc. Thus, after the suction hood straddles the central isolation belt, when the exhaust fan 3 works, it can suck away the garbage in the covered central isolation belt section, and can suck away the garbage while moving, with high working efficiency.

[0030] Valves can be provided at each air inlet 14, and the opening and closing of each valve can be determined according to the specific position of the garbage in the central isolation belt.

[0031] In an embodiment, the moving frame 1 is connected to the moving support through a cantilever 15, and the moving support is dragged by the moving frame 1 to move.

[0032] Now refer to Figure 5 , the flushing module includes a water tank 16, a water pump 17, and a drainage channel 18. When the water pump 17 works, it can prompt the liquid in the water tank 16 to spray out through the drainage channel 18 to flush the road. For example, the water outlet of the drainage channel 18 is close to and faces the bridge expansion joint. When the water pump 17 works, the high-pressure liquid flow formed can flush the bridge expansion joint, prompting the sundries, dust, soil, etc. in the bridge expansion joint to leave. The water tank 16 and the water pump 17 are both arranged on the moving frame 1.

[0033] The blowing module includes a hair dryer 19 and a second exhaust channel 20. When the hair dryer 19 works, it can form an air flow, and the air flow is discharged outward through the second exhaust channel 20 to blow away light sundries or dry the liquid remaining on the road. For example, the air outlet of the second exhaust channel 20 is close to and faces the bridge expansion joint. When the hair dryer 19 works, it can form an air flow to dry the bridge expansion joint flushed by the flushing module. The hair dryer 19 is arranged on the moving frame 1.

[0034] The blowing module may further include a heater 21, and the heater 21 is used to increase the temperature of the airflow formed by the blower 19. Specifically, the heater 21 may be arranged at the air outlet of the blower 19. The addition of the heater 21 can effectively improve the air drying efficiency of the blowing module.

[0035] In one embodiment, the outlet section of the drainage channel 18 and the outlet section of the second exhaust channel 20 are both fixed on the same regulator 22. The outlet section of the drainage channel 18 and the outlet section of the second exhaust channel 20 can be composed of multiple movable sections, or can be a partially flexible pipe. The regulator 22 includes a base 23 fixed to the mobile frame 1, a rotating arm 24 rotatably connected to the base 23, and a lock body 25 for locking the relative position of the base 23 and the rotating arm 24. The outlet section of the drainage channel 18 and the outlet section of the second exhaust channel 20 are both fixedly connected to the rotating arm 24, and the outlet section of the drainage channel 18 and the outlet section of the second exhaust channel 20 are adaptively adjusted as the position of the rotating arm 24 changes, so as to achieve the simultaneous change of the position of the outlet of the drainage channel 18 and the outlet of the second exhaust channel 20. For the expansion joint of the bridge that needs to be flushed and air-dried, only the rotating arm 24 needs to be adjusted once, and the work is more efficient. The rotating arm 24 can be provided with a switch for controlling the operation of the hair dryer 19 and the water pump 17, and the switching between the flushing mode and the air-drying mode can be realized through the switch.

[0036] Compared with traditional manual cleaning, the road maintenance and cleaning equipment of this embodiment is more efficient and can achieve the functions of sucking away garbage, flushing, and air drying.
