Specific embodiment
Below in conjunction with drawings and examples, the structure and principle that the present invention will be described in detail.
Fig. 1 is the leakage detector that one embodiment of the invention provides, and including the detection folder 1 with magnet ring and is used for fixed test
The ontology 2 of folder.The characteristics of detection is pressed from both sides be detection folder 1 left half folder and right half folder respectively be fixed on ontology 2 two turns
Moving axis 16 is rotatablely connected, and this two rotation axis 16 are detachably connected with ontology 2.Folder 1 and ontology 2 can be will test in this way
It separates, if the detection of different bores is needed to press from both sides, can individually be opened, no longer need to be opened for entire leakage detector, save significantly
About production cost.Magnet ring diameter provided by the invention is 35mm or 85mm, and those skilled in the art can also be according to need
Produce the magnet ring of other different bores.
As shown in Fig. 2, detection folder 1 includes clamping limb, rotating block and cursor.Two clamping limbs are respectively the first arc folder
Gripping arm 11 and the second arc clamping limb 12, their semicirculars in shape, both ends are docking together respectively forms closure magnet ring, and the
One, the first butt end of the second arc clamping limb is connected by spring 13, operates cursor, revolves rotating block around rotation axis
Turn, the second butt end of the first, second arc clamping limb can be made to open.Two rotating blocks are respectively the first rotating block 14 and
Two rotating blocks 15, two clamping limbs and two are rotated axis connection by them, and the opposite flank of two rotating blocks, which is equipped with, mutually to be interconnected
Dynamic engaging tooth rotates one of rotating block, i.e. another rotating block of linkage.Also, the first rotating block 14 and the first arc
Clevis gripping arm 11 is integrally formed, and the second rotating block 15, the second arc clamping limb 12 and cursor 17 are integrally formed.
As shown in figure 3, the specific structure of first/second arc clamping limb includes that semicircle detect presss from both sides plastic shell 21, two
The left semi-ring and right semi-ring of magnet ring are respectively equipped in a detection folder plastic shell 21, left/right semi-ring outer package presss from both sides plastics in detection
In inner casing 23, it is wrapped coil on detection folder plastic inner shell outer wall, metal screen layer 22 is equipped between coil and plastic shell, is used to
The magnetic field between magnet ring and the external world is shielded, is avoided and extraneous electromagnetic interference.
As shown in figure 4, magnet ring 24 of the invention is made of soft magnetic bodies, its specific structure is by multi-disc arc magnetic sheet layer
Folded to form, the head and the tail both ends of these magnetic sheets 241 are respectively arc end 242 and notch end 243, left and right semi-ring be connected to each other every two
The butt end of block magnetic sheet passes through arc end respectively and notch end is spliced.Since the both ends of plastic inner shell 23 are openings,
Magnetic sheet along the circumferential direction slides in order to prevent, its circumferencial direction of one lateral edge of inner periphery of plastic inner shell 23 is equipped at intervals with several limits
Position (not shown), several notches 243 are arranged in the position that the inner circumferential side of magnetic sheet 241 corresponds to positive stop strip, after assembling, lack
Mouth 243 blocks positive stop strip, thus fixed magnetic sheet 241.
In the prior art because multi-pass operation detection folder, the external force of generation are easy to cause rotation axis crooked, are no longer normal to
Body surface, this will so that the first, second butt end can not Dock With Precision Position again, the magnet ring being closed completely can not be formed.
Therefore, it in order to dock the left and right semi-ring of clamping limb middle magnetic ring can accurately again after opening operation, reduces in operation
Error is set on ontology there are two cylindrical positioning convex column, and positioning convex column is equipped with the screw thread being threadedly coupled with two rotation axis 16
The rotating block of slot, left half folder and right half folder is equipped with the circular locating slot being inserted into for positioning convex column, and positioning groove center is equipped with can
For the through-hole that rotation axis passes through, through-hole, locating slot, the setting of positioning convex column concentric.So under external force, operation rotation
Arm opens second butt end of two clamping limbs, not only can come back rotation, but also circular locating slot by axle center of rotation axis
Positioning convex column rotation can be covered, avoids external force that rotation axis is made to generate skew.Since rotation axis will not generate skew, cursor is unclamped
Make, clamping limb can close up again according to open track, be spliced into complete magnet ring, well solve in the prior art
Problem.
In addition, will receive some interference, such as wind blows detector, causes when detection is clipped on conducting wire to be measured
The effects of gravity power interference under, magnet ring can not be closed completely.Therefore, ontology of the invention is equipped with fixed column, in fixed column
It is cased with torsional spring, two elastic arms of torsional spring, which resist cursor, makes magnet ring be in closed state.
In the present embodiment, it is equipped with electronic signature capture analysis module 5 in ontology 2, also has LED light, for detection
The battery 4 of instrument offer power supply.When detection, electrified wire to be measured is made to pass through magnet ring, magnetic field can be generated in metal screen layer, it should
Magnetic field is walked along magnet ring, and the coil being centered around on plastic shell can be made to generate electric current, and electronic signature capture analysis module 5 can receive
This signal carries out analysis for current leakage.Electronic signature capture analysis module 5 is currently detected cable according to the signal analysis of detection ring
Real-time current, via each tested measuring point of concentrator Macro or mass analysis whether there is leaky, then will test result and collecting
Middle device end is shown, and produces detection archives.
Still further, the present invention is also provided with electronic lock, pressed from both sides for lock-in detection.Electronic lock includes locking plate 7, remote control electricity
The remote-control key of machine 8 and control remote-control motor.The tip inside of cursor is arranged in locking plate 7, opens folder for limiting cursor
Gripping arm, remote-control motor 8 are connect with locking plate 7, locking plate can be driven in the rotation in surface perpendicular to body surface, remote-control key is then
Remote-control motor can be remotely controlled, so that electronic lock is unlocked either and is latched, LED light can then prompt unlocking either latch like
State.
As shown in figure 5, the present invention is also provided with wireless communication module 6, can be communicated with handheld terminal PDA, e-mail
Number collection analysis module 5 will test the result that the magnetic induction ring in folder 1 detects and be acquired analysis, then wireless communication module
6 and antenna 3 result after analysis can be transferred to corresponding handheld terminal PDA.The present invention can also be from handheld terminal PDA
Download inter-related task information, such as device attribute, owner, Location, the route of administration, contact method, management unit
Deng, and once obtain test result, it can also be combined with these information, become complete information aggregate, retransmited
Give handheld terminal PDA.The present invention can name leakage point of electricity by the communication with handheld terminal PDA, display ownership incidence relation
Direction and maintenance task are clearly overhauled for operation maintenance personnel.
It should be understood that the above-mentioned description for specific embodiment is more detailed, can not therefore be considered to this
The limitation of invention patent protection range, scope of patent protection of the invention should be determined by the appended claims.
