Description

Pipeline plugging device Technical Field The utility model relates to the technical field of pipeline leakage repairing devices, in particular to a pipeline leakage plugging device. Background Gathering and transporting pipelines are one of main facilities for transporting various industrial media, and particularly, oil and gas gathering and transporting pipelines play a vital role in oil and gas field development and production. Along with the oil field entering the middle and later stages of development, the gathering and transportation pipeline has the phenomena of thorns, leaks and perforations due to corrosion, stress and the like, and the pipeline safe operation and the surrounding environment are greatly influenced. When the pipeline leaks, the gathering and transportation pipeline needs to be stopped or depressurized, the working face of the leakage point is cleaned, and the production can be recovered after the leak stopping construction is completed. Aiming at the condition of pipeline leakage, the prior art generally adopts a patching welding mode. Because the pipeline is filled with the mediums such as oil, gas and water, even in the stop conveying state, the conveyed mediums still flow out from the leakage point, so that the welding is difficult, firstly, the molten metal can be blown away by the sprayed mediums before being solidified, so that the welding quality and the construction efficiency are affected, secondly, the leaked mediums such as oil, gas and the like are inflammable and explosive, and the personal safety of welding personnel can be impaired when repair welding is carried out under the leakage dynamic state. Under the condition, on-site personnel generally adopt to manually plug the leakage point by using the cement, and then patch the leakage point for welding, but under the influence of the strength of the cement, under the action of pipeline pressure or under the condition that the joint surface of the patch and the pipeline is not tightly matched, the leakage point still has medium exudation, so that the working surface is not clean and the welding is difficult. Therefore, in order to solve the above-mentioned problem, chinese patent publication number CN207880290U of the 18 th 2018 9 discloses a crude oil transportation pipeline with pressure plugging device, which comprises an arc plate with a C-shaped structure, wherein the two ends of the arc plate are respectively provided with a pressing end and a tightening end, the tightening end is in butt joint with the outer wall of the pipeline, the pressing end is provided with a rotary screw, the rotary screw is in butt joint with the top of a plugging barrel, the bottom of the plugging barrel is provided with a profiling edge welded with the outer wall of the pipeline, the barrel wall of the plugging barrel is provided with a valve, the valve is connected with an oil storage tank through a hose, the outer wall of the pipeline can be hooked by the arc plate with the C-shaped structure and the plugging barrel is tightly pressed on a leakage point, the leaked oil water can be introduced into the oil storage tank before the plugging barrel is welded, and after the plugging barrel is fixedly welded, the valves on the plugging barrel and the plugging barrel drainage nipple are kept on a gathering pipeline, and the phenomenon of being damaged due to the fact that the oil gas gathering pipeline is generally in the wild. In addition, when the tightening end of the arc-shaped plate of the C-shaped structure in the pressurized plugging device is abutted against the outer wall of the pipeline, only one abutting point exists on the radial plane of the pipeline, so that the pipeline is unstable in clamping when the plugging barrel is jacked by adopting the rotary screw, the pipeline is likely to slip along the circumferential direction, the jacking position of the screw is moved, the leakage barrel cannot be jacked more stably, the plugging efficiency is reduced, and the risk of oil-water leakage exists. Disclosure of utility model The utility model provides a pipeline plugging device, which solves the problem that the existing plugging device is unstable in clamping of a pipeline during jacking. In order to solve the technical problems, the technical scheme of the pipeline plugging device is as follows: The utility model provides a pipeline plugging device, includes patch and can overlap the holder of establishing on the pipeline along pipeline circumferencial direction, the holder includes roof pressure part and butt portion, roof pressure part is equipped with the roof pressure piece for with patch roof pressure in the pipeline leakage position, the butt portion has the prismatic groove of opening orientation pipeline, and the prismatic border pipeline circumferencial direction in prismatic groove extends, the prismatic groove is used for the butt pipeline outer wall.
