Pipeline dredging and flow guiding tool for water conservancy construction

Abstract

The invention discloses a pipeline dredging and flow guiding tool for water conservancy construction. The pipeline dredging and flow guiding tool for water conservancy construction comprises a rotating head, an outer cylinder, an inner cylinder, a core body part and a back end cover; the rotating head comprises a conical shell-shaped body, the inner side wall of the body is provided with cutter teeth, the outer side wall of the body is provided with blades, and the length of the blades is gradually decreased from the large end of the body to the small end of the body; water outlet pipelines are arranged in a backward extending mode in the length direction of a core cylinder; the portion nearby the cavity bottom of a water injection cavity of the inner cylinder is provided with jetting holes used for jetting out water flow, and the water flow jetted out from the jetting holes exactly impacts the blades to drive the rotating head to conduct rotating cutting; and a conical thrust cone iscoaxially installed in the core cylinder in a hung mode, the cone tip of the thrust cone faces the small end port of the body, and an impeller used for enabling air to quickly flow towards a back portof the core cylinder is coaxially installed on the end face of the thrust cone. The device is high in dredging capability and extremely high in dredging efficiency.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering pipeline dredging, in particular to a pipeline dredging device. Background technique [0002] In the construction of water conservancy projects, the respective pipelines are often dredged. Many pipelines are difficult to unblock after being blocked. The common method is to connect a metal hose to a motor, and then rotate the motor so that the hose is not in the pipeline. Stir continuously to achieve the purpose of dredging, but this traditional tool is difficult to dredge the highly clogged pipeline, especially when the pipeline is almost completely clogged, and the clogged object is clogged and dense garbage such as mud-rock mixture, the traditional method The efficiency is extremely low and even the diversion cannot be successfully dredged. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems, and provi...
