Abstract

The invention discloses a rotating obstacle clearing drill bit. The rotating obstacle clearing drill bit comprises a drill bit body, a high-pressure water containing cavity is formed in the drill bitbody, multiple spiral water channels which are communicated in a cut-through mode along the cavity wall from top to bottom are arranged in the cavity wall of the high-pressure water containing cavity,and each spiral water channel comprises a water inlet and a water outlet, so that high-pressure water in the high-pressure water containing cavity enters the corresponding spiral water channels through the water inlets and flows out of the water outlets to exert forward driving force and rotating turning force to the rotating obstacle clearing drill bit. By arranging the spiral water channels, the rotating obstacle clearing drill bit rotatably advances at a high speed in a water drainage pipeline, and then the water drainage pipeline blocked by waste blockages can be dredged; and by arrangingblades used for cutting and crushing the blockages in the water drainage pipeline on the outer surface of the drill bit body, the rotating obstacle clearing drill bit has the high crushing capabilityon large soft waste blockages and hard waste blockages in the water drainage pipeline and can smoothly dredge the water drainage pipeline for the water drainage pipeline difficult to dredge.

Description

technical field [0001] The invention relates to the technical field of pipeline obstacle removal devices, in particular to a rotary obstacle removal drill bit. Background technique [0002] With the development of urban construction in the direction of modernization, the construction and maintenance of urban drainage facilities also need to keep up with the pace of urban development and growth. Drainage facilities are an important guarantee for the normal operation of cities. The smooth flow of drainage facilities can ensure that the urban environment is clean and hygienic, and residents healthy lifestyle. [0003] At present, due to the aging of facilities and insufficient supervision, the drainage pipes in many cities are seriously clogged, which directly affects the drainage capacity of the drainage pipes. In the rainy season, it may even form waterlogging. People's traffic trips will cause residential houses to be flooded more seriously, which will cause huge economic l...
