Description

Technical Field

[0001] This utility model relates to the field of sewage inspection well technology, and in particular to a mixing device for underground pipe network sewage inspection wells with adjustable depth. Background Technology

[0002] In underground sewage pipe network systems, pipes need to be regularly inspected and cleared of blockages. Sewage inspection wells are key structures in municipal drainage systems. As "maintenance windows," sewage inspection wells are prone to the deposition of suspended solids and organic matter in sewage after long-term operation, forming sludge. This leads to a reduction in the cross-sectional area of ​​the pipes, a decrease in drainage capacity, and even blockages. Mixing equipment breaks the stable deposition state of the sludge by mechanically agitating it, making it easier to pump or discharge with the water flow after suspension. Since sewage inspection wells have different depths, the mixing depth of the mixing equipment needs to be adjusted to adapt to the mixing operation of sewage inspection wells of different depths. However, the existing publicly available sewage inspection well mixing equipment still has some shortcomings in practical applications that need to be improved, such as: The handheld method of stirring the sewage inspection well is laborious, the stirring position is not accurately controlled during the stirring process, the stirring blades are prone to damage when they hit the inner wall of the sewage inspection well, which is not conducive to the service life of the stirring equipment and the stirring equipment is inconvenient to use. The fixed angle and mixing range of the agitator blades result in low adaptability to sewage inspection wells, hindering operational flexibility. Furthermore, the agitator blades are integrally welded to the drive shaft, making blade replacement inconvenient and increasing maintenance costs. Therefore, those skilled in the art have provided an underground pipe network sewage inspection well mixing device with adjustable depth to address the problems mentioned in the background section.
