specific Embodiment 1

[0056] see Figure 1-3 , the present invention provides a pipeline current monitoring device, which is set on the pipeline and used to monitor the pipeline current, including:

[0057] The soft magnetic magnetic ring is formed by connecting two arc-shaped soft magnetic parts sequentially end to end through connecting parts, and generates a magnetic field based on the current in the pipeline;

[0058] The connecting parts are divided into two types: the first connecting part (21) and the second connecting part (6);

[0059] Wherein, the first connecting part (21) is an opening and closing mechanism, when in the closed state, an air gap is formed between the ends of two adjacent soft magnetic parts connected by the first connecting part (21) (7);

[0060] The signal detection probe (3) is a Hall sensor installed in the air gap (7) and connected to the external signal transmitter (5) through a wire (4) for the magnetic field generated based on the soft magnetic ring Detect the...

specific Embodiment 2

[0093] see Figure 5 , the soft magnetic magnetic ring of this embodiment is composed of a first soft magnetic component, a second soft magnetic component and a third soft magnetic component;

[0094] The head end of the first soft magnetic component is connected to the tail end of the second soft magnetic component through a first connecting component (21);

[0095] The tail end of the first soft magnetic component is connected to the head end of the third soft magnetic component through a second connecting component (6);

[0096] The tail end of the third soft magnetic component is connected to the head end of the second soft magnetic component through a second connection component (6).

[0097] Specifically, the connection mode of the first connection part (21) is a bolt connection; the connection mode of the second connection part (6) is a hinge connection.

[0098] The difference between this embodiment and Embodiment 1 is that the soft magnetic component is made of thr...

specific Embodiment 3

[0101] Figure 6-7 It is a schematic diagram of the overall structure of a pipeline current monitoring device according to another embodiment of the present invention.

[0102] The difference between this embodiment and Embodiment 1 lies in that the first connecting part ( 21 ) and the second connecting part ( 6 ) are connected by bolts.

[0103] The fixing and connection of other component structures are the same as in Embodiment 1. Therefore, when manufacturing the pipeline current monitoring device, it is only necessary to change the hinge connection method to the bolt connection method, and the other soft magnetic materials, insulation materials, and manufacturing methods are the same as in Embodiment 1.

Abstract

The invention relates to a pipeline current monitoring device and a manufacturing method thereof. The pipeline current monitoring device sleeves a pipeline and is used for monitoring pipeline current. The pipeline current monitoring device comprises a soft magnetic ring which is formed by sequentially connecting at least two arc-shaped soft magnetic parts end to end through a connecting part; the connecting part is divided into a first connecting part and a second connecting part; the first connecting part is an opening and closing mechanism, and when the first connecting part is in a closing state, an air gap opening is formed between the end parts of the two adjacent soft magnetic parts connected by the first connecting part; a signal detection probe is mounted in the air gap and is connected with an external signal transmitter through a wire; and a signal transmitter is connected with a signal receiving device of a monitoring station in a wireless communication mode. The pipeline current data visualization can be realized through the signal detection probe, the real-time condition of the pipeline can be further mastered, and the characteristics of simple manufacturing process, few components, short time consumption, low cost and high safety are realized.

Description

technical field [0001] The invention relates to the field of pipeline current monitoring equipment manufacturing, in particular to a pipeline current monitoring device and a manufacturing method thereof. Background technique [0002] With the development of the petrochemical industry and the acceleration of urbanization, the scale of underground pipeline grids has gradually expanded. Therefore, the safety of buried pipelines has become increasingly prominent. As we all know, most of the corrosive media transported in buried pipelines are oil and gas corrosive media, which are corroded by transport media, soil, and groundwater for a long time, and the pipe wall will become thinner due to corrosion. Once a problem occurs, it will seriously endanger people's lives and Property security. In addition, the rapid construction of domestic high-voltage direct current transmission lines, high-speed railways and subways and other urban traffic, the AC and DC stray currents generated b...
