Negative pressure vibration type dredging device for blocking pipeline

Abstract

The invention discloses a negative pressure vibration type dredging device for blocking a pipeline. The negative pressure vibration type dredging device includes a main hollow shell. Anegative pressure state caused by air extraction is used to linka blocked part inside the pipeline, and then a piston part is used to move in negative pressure space, and thus making a blocking object of the locked part loosen in a constant shock, so thatan initial dredging function is achieved as an initial dredging to use under an emergency state. The device has an elastic longitudinal cushioning support mechanism of a helical spring, and an elastic support under the action of the helical spring is achieved, so that adsorption and expansion capacities are achieved. In addition, the device has a piston typeup-down micro air pressure link mechanism, and under the negative pressure state and under an electromagnetic principle action, an internal air state linkage is achieved, so that vibration of the blocking object is driven.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging, in particular to a negative pressure oscillation dredging device for blocked pipelines. Background technique [0002] At present, in some places, underground pipelines are required to transport and discharge some liquids, and after a long period of working conditions, blockages often occur, and in some specific places, once blockages occur, serious water accumulation will occur. The general method is to open the blocked part to dredge, and the process is relatively long, so the damage rate is too high and the limitations are relatively large. Contents of the invention [0003] The object of the present invention is to provide a negative pressure oscillation dredging device for blocked pipelines, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solution...
