Problems solved by technology
[0003] However, when the existing sewage gas extraction device is in use, most of the suction pipes are deep into the pipeline to extract air, and the extraction efficiency is low. When the pipeline sewage extraction device with walking function is in use, the supported diameter adjustment range Smaller, the scope of use is limited. At the same time, the supporting legs sometimes separate from the pipe diameter during the sliding process, resulting in unbalanced force and inconvenient sliding. Moreover, most of the air supply process uses pipes to directly supply air. poor uniformity

The invention discloses a foul gas extraction device for municipal pipeline internal maintenance. The foul gas extraction device comprises a sliding box body and a breathable mesh enclosure, wherein apush handle is fixedly connected below one side wall of the sliding box body; an operation controller is fixedly connected to one side, positioned above the push handle, of the sliding box body; andan exhaust pipe is arranged on one side above the operation controller. Through the action of a telescopic push rod, telescopic supporting legs slide along a guide sleeve, the supporting diameters ofthe telescopic supporting legs are adjusted, thus the foul gas extraction requirements of municipal pipelines with different pipe diameters are met, and the application range is wide; and an elastic supporting assembly is arranged between the telescopic supporting legs and a push rod support, an elastic acting force can be provided for the telescopic supporting legs, the influence of small changeof the inner diameter size of the pipeline can be avoided, ball wheels on the telescopic supporting legs can be always ensured to be firmly attached to the inner wall of the pipeline, then the devicecan be ensured to flexibly slide in the pipeline, the position movement is labor-saving and time-saving, and the device is extremely practical.
Description
technical field [0001] The invention belongs to the technical field of municipal pipeline maintenance, and in particular relates to a sewage gas extracting device for internal maintenance of municipal pipelines. Background technique [0002] As the city's drainage pipe network, municipal pipes play an important role in flood drainage and drainage. During use, the plastic corrugated pipes will rupture due to external stress, and the common cleaning and maintenance devices mainly It is used to confirm the specific location of the rupture, and to carry out pipeline repair work through external digging and positioning. In the process of pipeline maintenance, a sewage extraction device is required. [0003] However, when the existing sewage gas extraction device is in use, most of the suction pipes are deep into the pipeline to extract air, and the extraction efficiency is low. When the pipeline sewage extraction device with walking function is in use, the supported diameter adju...
