Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the present invention includes bottom centre and be provided with the lower box body 8 that the upper cartridge body 1 of notch 6 and top center are provided with lower notch 9, in the middle part of both rear sides, adopt jointed shaft 7 to be articulated and connected.Both upper cartridge body 1 and lower box body 8 can free-open-closes, and opening rear power transmission line 17 can by embedding between the two, and after closed, power transmission line 17 is positioned at the space that notch 6 and lower notch 9 are formed.
The front side wall of upper cartridge body 1 offers the jack of strip, affixed on the front side wall of lower box body 8 pedestal 13 is installed, also comprise coordinating with jack and line-locked lockplate is entered to the buckling state of both upper cartridge body 1 and lower box body 8.Lockplate comprise plate body that middle part is articulated and connected with pedestal 13 and be positioned at plate body top, the enchasing plate 2 that can embed or depart from jack, the leading edge of enchasing plate 2 is circular arc, root edge is straight.In the present embodiment, lockplate comprise be positioned at top, the first straight plate body 3 and be positioned at below, the second plate body 15 of bending shape, be provided with otic placode in both junctions, otic placode and pedestal 13 are articulated and connected.Pedestal 13 is also provided with between the second plate body 15 and the front side wall of lower box body 8, to provide reseting elasticity torsion spring 14.By laterally pressing the lower end of the second plate body 15, lockplate is unitary rotation centered by the jointed shaft of both otic placode and pedestal 13, and the enchasing plate 2 of top is deviate from by jack, removes upper cartridge body 1 and the buckling state both lower box body 8.Torsion spring 14 should have enough intensity, makes enchasing plate 2 be plugged on securely in jack, prevents from deviating from voluntarily under external shock is as the effect of the factors such as wind-force vibrations.
Be provided with in upper cartridge body 1 in semi-ring iron core, lower box body 8 and be provided with lower semi-ring iron core and control circuit board, after both upper cartridge body 1 and lower box body 8 fasten, upper semi-ring iron core and lower semi-ring iron core form complete annular core.Now, above-mentioned annular core is set in the outside of power transmission line 17, detects the electric current in power transmission line 17, the voltage condition i.e. situation of transmitting electricity.Control circuit board at least should comprise controller unit, advance signal processing unit and wireless transmit/receive units, the signal that advance signal processing unit records for the treatment of annular core, above-mentioned data are sent to control station by cordless communication network and receive instruction by control station by wireless transmit/receive units, and controller is for controlling overall operation.Can also storage unit be comprised, make detector possess the ability of history data store and inquiry reading.
The front and back inwall of upper notch 6 is provided with the seat 4 that is relatively fixed, and on holder 4, the affixed stage clip 12 being provided with two U-shapeds in left and right of triangularity bifurcated, is connected with the reeded cushion block 10 of top center band at the bottom land of lower notch 9.Power transmission line 17 is positioned at the groove of cushion block 10, and power transmission line 17 crimps fixing by stage clip 12, and the loading namely completing detector is fixed.
In the present embodiment, stage clip 12 is processed into by same elastic metallic bar, formed in both sides two the triangularity bifurcateds in left and right, the press keeping section of U-shaped, between two press keeping sections, form two spiral winding in left and right, two spiral winding adopt that screw 5 is affixed to be arranged on two holders 4 respectively.The advantage adopting screw 5 to be fixed installation is convenient to change stage clip 12, and stage clip 12 needs to carry out selecting to reach optimum fixed effect according to the size of power transmission line 17, and the rear compression spring 12 meeting lost its bounce of use for a long time, also needs to change.In the present embodiment, in order to promote the centering effect to power transmission line 17, be equipped with the curved portions 11 raised up at the middle part of each press keeping section, power transmission line 17 is fixed in place with the groove fit of cushion block 10 by curved portions 11, promotes the precision that annular core detects.
In the present embodiment, in order to promote the fixed effect of power transmission line 17, multiple tracks fin can be set on the cell wall of the groove of cushion block 10.
In the present embodiment, the indicator 16 indicated the malfunction of current power transmission line 17 is also installed in the bottom of lower box body 8.Indicator 16 can be chosen for mechanical type, such as can comprise the mark of rotating, bright-colored (being generally red), deflect under the effect of a dynamical element (micromachine or electromagnet), brightly painted part is exposed or hides, when above-mentioned part is exposed, maintainer can observe comparatively remote (usually immediately below detector), determine that current power transmission line 17 needs maintenance, when above-mentioned part is hidden, indicating status is normal transmission state.This kind of structure needs configuration low-power indicating lamp device, for indicating at night.
Fig. 2 is the side-looking structural representation of installment state, can find out: after both upper cartridge body 1 and lower box body 8 are opened, workmen by one independently erecting device this detector is held up, power transmission line 17 is made to embed, above-mentioned erecting device should have one and automatically press down parts, presses down upper cartridge body 1, until enchasing plate 2 embeds in jack, now power transmission line 17 is between curved portions 11 and the groove of cushion block 10, and namely whole detector completes loading.When needing unloading, only a discharge mechanism need be adopted to hold this detector, the lower end making a movable part stir lockplate makes enchasing plate 2 deviate from by jack.
