Abstract
The utility model discloses a cable measuring device, which comprises an electromagnetic sensor and a signal display unit. The electromagnetic sensor is arranged around a cable to be detected, the signal display unit is used for reflecting changing field signals in the electromagnetic sensor, transforming the changing field signals into electric signals and displaying the electric signals, the electromagnetic sensor comprises a first semi-ring body and a second semi-ring body, which are made of magnetic material, and the first semi-ring body and the second semi-ring body form a closed-loop magnetic circuit when being connected with each other. When the utility model is used, the detection can be performed in accordance with the electromagnetic induction principle, only with the two semi-rings sleeved on the cable to be detected and connected to form an enclosed ring, and the utility model can rapidly judge whether the core wire detected is subject to failure. Moreover, the utility model has the advantages of simple structure and convenient use.
Description
Technical field
The utility model relates to the cable fault detection range, relates in particular to a kind of cable survey line device that is used for the out of order heart yearn of detection streamer.
Background technology
General cable all includes the multiply heart yearn, in the long-time running of cable, because a variety of causes, as external force damage, chemical corrosion, overload operation, cable splice fault, environment and temperature, normal aging and disaster etc., one or several strands of heart yearns in the cable are broken down, therefore it is very important cable core being detected in advance, can early find the minor failure of heart yearn, prevents from finally to cause whole cable to scrap.But the cable fault detecting device complex structure of prior art, use also not too convenient.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of cable survey line device simple in structure, easy to use at above-mentioned deficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: cable survey line device comprises the electromagnetic sensor that is used for around detected cable; Signal display unit is used to reflect the field signal that changes in the described electromagnetic sensor, and with its conversion and be shown as electric signal; Described electromagnetic sensor comprises first hemizonid and second hemizonid of being made by permeability magnetic material, forms the closed loop magnetic circuit when described first hemizonid docks with second hemizonid.
As optimized technical scheme, described first hemizonid and second hemizonid are formed by stacking by siliconized plate respectively.
As optimized technical scheme, described signal display unit comprises the inductive coil that is wrapped on the described hemizonid, and connects into the galvanometer of loop with described inductive coil.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because the electromagnetic sensor in this cable survey line device comprises first hemizonid and second hemizonid of being made by permeability magnetic material, form the closed loop magnetic circuit during two hemizonid butt joints, when the heart yearn in the tested cable is carried out fault detect, as long as be enclosed within these two hemizonids on the cable under test and be docking together and form a closed-loop, certain strand of heart yearn to be measured is passed to alternating current, according to electromagnetic induction principle, size and Orientation changes and magnetic field that the alternating current that changes can change in electromagnetic sensor in time, the magnetic field that changes can produce induction current in the inductive coil of the signal display unit that seals, and shows this induction current by galvanometer.Because the final induction current that produces was different when out of order heart yearn passed to alternating current respectively with trouble-free heart yearn, the induction current that produces when passing to alternating current with trouble-free heart yearn is made comparisons, can judge quickly whether tested heart yearn exists fault, simple in structure, easy to use.

Below in conjunction with accompanying drawing the utility model embodiment is described further.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-electromagnetic sensor; 11-first hemizonid; 12-second hemizonid; The 2-signal display unit; The 21-inductive coil; The 22-galvanometer; The 3-cable; The 31-heart yearn.
Embodiment
As shown in drawings, cable survey line device comprises the electromagnetic sensor 1 that is used for around detected cable 3; Signal display unit 2 is used to reflect the field signal that changes in the described electromagnetic sensor 1, and with its conversion and be shown as electric signal; Described electromagnetic sensor 1 comprises first hemizonid 11 and second hemizonid of being made by permeability magnetic material 12, forms the closed loop magnetic circuit when described first hemizonid 11 docks with second hemizonid 12.During use, form a closed-loop, can detect as long as be enclosed within these two semi-rings on the cable under test and be docking together, simple in structure, easy to use.
Described first hemizonid 11 and second hemizonid 12 siliconized plate low by iron loss respectively, that magnetic induction density is high is formed by stacking.
Described signal display unit 2 comprises and is wrapped on described first hemizonid 11 inductive coil 21, and connects into the galvanometer 22 of loop with described inductive coil 21.The induction current that induction current that the tested heart yearn 31 that galvanometer 22 is shown produces when passing to alternating current and trouble-free heart yearn produce when passing to alternating current is made comparisons, and can judge quickly whether tested heart yearn 31 exists fault, and is easy to use.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, but those of ordinary skills can make various distortion or modification to embodiment, and not deviating from principle of the present utility model and essence, scope of the present utility model is limited by appended claims.
