So as to allow another sealed fixing device inlet opening (13a) and fluid hole (13b) come realize input/discharge cleaning solution, enter
And make the input/discharge path of cleaning solution diversified.During practice, pipeline is probably to be vertically arranged, it may be possible to perpendicular
To being obliquely installed, it is also possible to horizontally disposed, thus robot may in pipeline upper and lower vertical shift, it is also possible to it is upper and lower
Inclination movement, it is also possible to move horizontally；The reasons such as the set-up mode limitation due to pipeline, may cause can only be from the one of pipeline
Side is input into/discharge cleaning solution, it is also possible to from the both sides of pipeline cleaning solution, therefore robot can be input into/discharged at two
Inlet opening (13a) and fluid hole (13b) are equipped with the fixed disk (13) of sealed fixing device, pipe can be thus well adapted for
The installation situation in road, this structure design seems simple, unnecessary, but can guarantee practice.
Using above technical scheme, the utility model is matched somebody with somebody by radial expansion component and two the organic of sealed fixing device
Conjunction can be moved along inner-walls of duct, and be input into/discharge cleaning solution to the chamber between two sealed fixing devices, and two close
Chamber between envelope fixing device can be done by round brush brush inner-walls of duct, cleaning solution when being input into cleaning solution with the organic cooperation of round brush
Only, dirt efficiently on removal inner-walls of duct, cannot clean right angle setting, length long, interior efficiently against prior art
The defect of the excessive or too small inner-walls of duct in footpath, and the utility model compact conformation, entire outer diameter size are small, external diameter excursion
Greatly, accommodation is big, it is easy to manufacture, cheap.
Used as decision design of the present utility model, the liquid pass hole (14a) is scallop hole, and its number is 6, and these cross liquid
(14a) is distributed on same circumference in hole；The inlet opening (13a) and fluid hole (13b) are distributed on same circumference, and inlet opening
