Description
Technical field
The utility model belongs to electric detective technology, relates to sensor detecting and automation field simultaneously, is specially a kind of portable pipe leakage magnetic detection device.
Background technology
Under existing scientific and technological background condition, piping system has been widely used in industrial sectors such as metallurgy, oil, chemical industry and city hot-water heating supply.Yet the condition of work of industrial pipeline is all very abominable usually, and corrosion and fatigure failure very easily take place pipeline, and its inner latent defect develops into breakage and causes leakage.And the medium in the pipeline is high temperature, high pressure, poisonous, flammable or corrosive fluid mostly.If leakage accident takes place, light then cause the waste of the actuating medium loss and the energy, contaminated environment, heavy then jeopardize personal safety, cause the great person and equipment breakdown.Therefore, pipe detection is very important to guaranteeing pipe safety.
The utility model content
The technical matters that the utility model solved is to provide a kind of portable pipe leakage magnetic detection device, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved realizes by the following technical solutions:
The portable pipe leakage magnetic detection device, some sensors and the wave filter installed before comprising controller and being connected controller output end, its sensor front portion connects magnetizing head and scanning instrument by interface, wave filter then is installed in series at the sensor rear portion, in addition, be connected to controller at the wave filter rear portion by the A/D change-over circuit; Simultaneously, described magnetizing head is provided with a pair of pole shoe, and this pole shoe is connected on the magnetizing head by a detachable seat.
In the utility model, magnetizing head is along the axis direction local magnetized pipeline of pipeline, and the arc surface of outer wall with radian made and managed on the pole shoe surface that contacts with pipeline outer wall, can adapt to the tested pipeline of various outer diameter by detachable seat replacing pole shoe.
In the utility model, described controller adopts 51 series monolithics.
In the utility model, also be provided with an amplification and rectification circuit plate between described sensor and the wave filter.
In the utility model, the controller rear end also is connected with input equipment and display device, to make things convenient for man-machine interaction.
Advantage of the present utility model and beneficial effect are:
1), human oriented design, be easy to carry, low consumption, fast and highly sensitive.
2), the sensitivity of high sampling, reduce rate of false alarm, and kept original signal information as much as possible, help real-time processing.
3), realize simply, cost is low: adopt microprocessor to realize the integral body control of system being proven technique as controller, easy to implement, drop into not highly, help promotion and implementation.
4), be convenient to expansion: adopt distributed field bus communication, wiring is simple, helps the expansion of system.
5), help promoting: the widespread use of piping system, very considerable to the economic benefit of their enforcement detections, social value is big.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the portable pipe leakage magnetic detection device of Fig. 1, in the present embodiment, total system comprises magnetizing head 1, scanning instrument 2, hall sensor 3, shaping amplification circuit 4, wave filter 5, A/ D change-over circuit 6, controller 7, supervisory keyboard 9 and waveform oscilloscope 8.Wherein, described magnetizing head 1, scanning instrument 2 are connected with controller 7 through hall sensor 3, shaping amplification circuit 4, wave filter 5 and A/ D change-over circuit 6; And described supervisory keyboard 9 all directly links to each other with controller 7 with waveform oscilloscope 8.
The course of work of native system is as follows:
Magnetizing head 1 is along the axis direction local magnetized pipeline of pipeline, and the arc surface of outer wall with radian made and managed on the pole shoe surface that contacts with pipeline outer wall.In pipeline outer wall and the equidistant place of bipolar shoe, along a plurality of hall sensors 3 of the circumferential word order of pipeline, the consistance of regulating each passage just can guarantee that the data of gathering are comprehensive, the defect situation of the pipeline that explains in precise term.
This pick-up unit can detect the inner and outer walls of pipeline defective in real time along the axis direction scanning of pipeline.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
