Embodiment 1

[0031] Such as figure 1 As shown, the present invention includes a pipeline 1, which is connected with a conveying device 2 for conveying the pipeline 1; it is characterized in that, a metal piece 2 is placed inside the pipeline 1, and an electromagnetic induction system 3 and an electromagnetic induction system 3 are respectively arranged outside the pipeline 1. The electromagnetic induction system 3 includes an alarm 31 for the magnet 4 that holds the metal piece 2 .

[0032] The magnet 4 of the present invention can attract the metal piece 2 in the pipeline 1, and the metal piece 2 will not move during the transportation of the pipeline 1. When the inner wall of the pipeline 1 is deformed, the protrusion at the deformed place will take away the metal part 2, so that the on-off of the electromagnetic induction system 3 changes, and the on-off of the alarm 31 changes, reminding the staff to take corresponding measures. The present invention detects the deformation of the pip...

Embodiment 2

[0034] Such as figure 2 As shown, on the basis of Embodiment 1, the electromagnetic induction system 3 also includes a main electric switch 32, the main electric switch 32 is electrically connected to an AC contactor 33, and the AC contactor 33 is electrically connected to a metal inductor 34, and the metal induction The alarm 34 is set close to the area where the metal piece 2 is arranged on the pipeline 1, and the alarm 31 is electrically connected to the AC contactor 33.

[0035] When the inner wall of the pipeline 1 is deformed, the metal piece 2 is taken away by the pipeline 1, and the connection contact of the AC contactor 33 changes. If the alarm 31 is connected to the normally closed contact of the AC contactor 33, the alarm 31 changes from disconnection to connection, and the alarm 31 sends out an alarm. If the alarm 31 is connected to the normally open contact of the AC contactor 33, the alarm 31 changes from a circuit to an open circuit, and the alarm 31 stops sen...

Embodiment 3

[0037] On the basis of Embodiment 1 or Embodiment 2, a cutting machine 5 is installed on the running path of the pipeline 1 .

[0038] When the worker learns through the information of the alarm 31 that the pipeline 1 passing through the magnet 4 has deformation, start the cutting machine 5 to cut off the deformed pipe section.

Abstract

The invention relates to the field of pipeline detection, and particularly relates to a detection alarm system for automatically checking deformation of an inner wall of a pipeline. The technical scheme is the detection alarm system for automatically checking deformation of the inner wall of the pipeline comprises a pipeline; the pipeline is connected with a conveying device for conveying a pipeline; a metal piece is placed in the pipeline, and the pipeline is externally provided with an electromagnetic induction system and a magnet for sucking the metal piece respectively; the electromagnetic induction system comprises an alarm. The invention provides the detection alarm system for automatically checking if the inner wall of the pipeline is deformed; the detection alarm system solves the problems that the existed pipe wall detection device cannot detect the deformation of the inner wall of the pipeline, and the detection result is unreliable.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a detection and alarm system for automatically checking the deformation of the inner wall of a pipeline. Background technique [0002] PP-R pipe is also called three-type polypropylene pipe and random copolymerized polypropylene pipe or PPR pipe. Long service life and other advantages, widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. The PP-R pipe is made of random copolymerized polypropylene, which is extruded into pipes and injection molded into pipe fittings. In the production of PP-R pipes, it is necessary to ensure that the inner wall of the pipe is not deformed to ensure the normal use of the pipe. [0003] In the existing technology, when detectin...
