Pipeline dredging and guiding device for water conservancy construction

Abstract

The invention discloses a pipeline dredging and guiding device for water conservancy construction. The pipeline dredging and guiding device comprises a rotating head, an outer cylinder, an inner cylinder, a core assembly and a rear end cover, wherein the rotating head comprises a conical shell-shaped main body, cutter teeth are arranged on the inner side wall of the main body, blades are arrangedon the outer side wall of the main body, and the blades are gradually shortened from the large end to the small end of the main body; an outlet of a water outlet pipeline is arranged by facing a cutting face of the rotating head; jet holes for ejecting water flow are formed nearby the bottoms of water injection cavities of the inner cylinder, and the water flow ejected from the jet holes just impacts the blades to drive the rotating head to perform rotary cutting; a mandrel is connected with a bullet structure through a connecting rod fixed on the inner wall of a core tube to be fixed in the core tube in a suspended manner, the rear end of a rotating shaft is mounted on the rear end cover, and a hollow cavity of the rear end cover is communicated with the water injection cavities of the inner cylinder; a discharge port penetrating through the inner cylinder and the outer cylinder is formed in the lower side wall, close to the rear end cover, of the core tube. The device is high in dredging capacity and quite high in dredging efficiency.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering pipeline dredging, and in particular relates to a pipeline dredging tool. 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,...
