Embodiment Construction

[0011] Now further illustrate the specific structure and operation mode of the present invention in conjunction with accompanying drawings and embodiments.

[0012] Figure 1 It is a schematic diagram of the structure of a plug-removing pig.

[0013] Such as Figure 1 In the shown embodiment, the blockage-removing pig is composed of a cleaning-type pig and a generating device. It can be seen from its appearance that it is basically a cleaning type cup cleaner, but there is a discharge unit (1, 2) of a generating device at its front end, and its skeleton is the housing (6) of the generating device. The structure of the skeleton is designed and manufactured according to the technical requirements of the pig and the generating device, that is, compressive strength, high voltage resistance, sealing, and shockproof. In this embodiment, the housing (6) has a cylindrical structure, and its diameter is not larger than 1 / 2 of the outer diameter of the pig, but there is a protrusion in...

Abstract

The present invention is one kind of pipe unblocking device as one pipeline cleaning device. The pipe unblocking device has battery powered pulse plasma generator and conventional pipeline cleaner installed coaxially. The pulse plasma generator consists of sensor, battery set, and energy accumulating and discharging unit. The discharging unit is one spark gap with rotation ellipsoid surface set in front of the pipeline cleaner to produce in liquid medium pulse plasma and chock wave. The rotation ellipsoid surface has the effect of reflecting shock wave and converging energy. In case of blocking or serious scaling, the sensor starts up the pulse plasma generator to generate shock wave to unblock and scale. The present invention has high operation efficiency and expanded operation range.

Description

Technical field [0001] The invention relates to a blockage-removing pipe pig which combines a conventional pipe pig and a pulse plasma generator, and belongs to pipeline cleaning equipment. Background technique [0002] Pipe pig technology is a technology that uses the flowing fluid medium to push the pig to advance in the pipeline and clean the pipeline. Pigging operations such as scale, rust removal, wax removal, isolation, and inspection. But existing pipe pigs basically do not have the function of deblocking at present. [0003] High-pressure water jet technology and pulsed plasma technology in liquid media have good functions of cleaning scale and plugging. The former has been used in pipeline cleaning operations with a length of less than 150 meters, and the latter has been successfully used in oil-water dredging. try. Due to the difficulty of long-distance water supply and power supply, the application range of these two technologies is limited. Contents of the i...
