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 and Fig. 2, the present invention includes bottom centre and be provided with the lower box body 3 that the upper cartridge body 1 of notch 9 and top center are provided with lower notch 7, in the middle part of both rear sides, adopt jointed shaft 2 to be articulated and connected.Both upper cartridge body 1 and lower box body 3 can free-open-closes, and opening rear power transmission line 19 can by embedding between the two, and after closed, power transmission line 19 is positioned at the space that notch 9 and lower notch 7 are formed.
The outer wall of the anterior side of upper cartridge body 1 is provided with centered by jointed shaft 2, the upper end arc-shaped rack 11 with fixed head 10, and fixed head 10 is fixedly connected with the sidewall of upper cartridge body 1, as shown in FIG. for adopting multiple dormant bolt to fix.Horizontal rotating shaft is provided with in the front portion of lower box body 3, the two ends of this rotating shaft are passed by the sidewall of lower box body 3 and are separately installed with gear 12 and ratchet 15, both gear 12 and ratchet 15 synchronous axial system, its middle gear 12 is connected with a joggle with arc-shaped rack 11, the sidewall of lower box body 3 is also provided with the ratchet 18 controlling ratchet 15 and rotate, ratchet 18 is provided with the torsion spring 17 providing reseting elasticity.When upper cartridge body 1 fastens on lower box body 3, arc-shaped rack 11 driven gear 12 rotates, with gear 12 altogether dog end 15 cis-position rotates, ratchet 18 keep under the reseting elasticity effect of torsion spring 17 and ratchet 15 tooth contact and prevent from turning round.When needing both upper cartridge body 1 and lower box body 3 to open, only need stir ratchet 18 discharges ratchet 15, and arc-shaped rack 11 can depart from gear 12.
In the present embodiment, in order to promote the convenience of ratchet 18 being stirred to movement, drop handle 16 can be set in the outer end of ratchet 18.As shown in FIG., when upwards holding up drop handle 16, the end of ratchet 18 departs from the gear teeth of ratchet 15, and ratchet 15 is discharged revolution.
Be provided with in upper cartridge body 1 in semi-ring iron core, lower box body 3 and be provided with lower semi-ring iron core and control circuit board, after both upper cartridge body 1 and lower box body 3 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 19, detects the electric current in power transmission line 19, 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 9 is provided with the seat 4 that is relatively fixed, and on holder 4, the affixed stage clip 6 being provided with two U-shapeds in left and right of triangularity bifurcated, is connected with the reeded cushion block 13 of top center band at the bottom land of lower notch 7.Power transmission line 19 is positioned at the groove of cushion block 13, and power transmission line 19 crimps fixing by stage clip 6, and the loading namely completing this pick-up unit is fixed.
In the present embodiment, stage clip 6 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 6, and stage clip 6 needs to carry out selecting to reach optimum fixed effect according to the size of power transmission line 19, and the rear compression spring 6 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 19, be equipped with the curved portions 8 raised up at the middle part of each press keeping section, power transmission line 19 is fixed in place with the groove fit of cushion block 13 by curved portions 8, promotes the precision that annular core detects.
In the present embodiment, in order to promote the fixed effect of power transmission line 19, multiple tracks fin can be set on the cell wall of the groove of cushion block 13.
In the present embodiment, the indicator 14 indicated the malfunction of current power transmission line 19 is also installed in the bottom of lower box body 3.Indicator 14 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 19 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.
Using method: after both upper cartridge body 1 and lower box body 3 are opened, workmen by one independently erecting device this pick-up unit is held up, power transmission line 19 is made to embed, above-mentioned erecting device should have one and automatically press down parts, upper cartridge body 1 is pressed down, until two box bodys remain on closure state under detaining the effect being incorporated in gear 12, arc-shaped rack 11, ratchet 15 and ratchet 18 completely, now power transmission line 19 is between curved portions 8 and the groove of cushion block 13, and namely whole pick-up unit completes loading.When needing unloading, only a discharge mechanism need be adopted to hold this pick-up unit, make a movable part stir ratchet 18 (drop handle 16) and ratchet 15 is discharged.
