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 8 that the upper cartridge body 1 of notch 5 and top center are provided with lower notch 6, 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 can by embedding between the two, and after closed, power transmission line is positioned at the space that notch 5 and lower notch 6 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 10 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 10 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 12 of bending shape, be provided with otic placode in both junctions, otic placode and pedestal 10 are articulated and connected.Pedestal 10 is also provided with between the second plate body 12 and the front side wall of lower box body 8, to provide reseting elasticity torsion spring 11.By laterally pressing the lower end of the second plate body 12, lockplate is unitary rotation centered by the jointed shaft of both otic placode and pedestal 10, 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 11 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, detects the electric current in power transmission line, 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.
In upper notch 5, hold down gag 4 is installed, is connected with the reeded cushion block 9 of top center band at the bottom land of lower notch 6.Hold down gag 4 comprises the upper plate body 4-1 that be connected affixed with the cell wall of upper notch 5, is hingedly connected with upper branch arm 4-3, is hingedly connected with lower branch arm 4-5 in the lower end of two upper branch arm 4-3 respectively by the second mandrel 4-4 at its two ends by the first mandrel 4-2; Also comprise the lower body 4-6 that lower surface is connected with the liner 4-8 of quality of rubber materials, the two ends of lower body 4-6 are articulated and connected in the lower end of two lower branch arm 4-5 by the 3rd mandrel 4-7 respectively, set up the second spring 4-10 setting up between the first mandrel 4-2 and the 3rd mandrel 4-7 of side between the first spring 4-9, the first mandrel 4-2 of opposite side and the 3rd mandrel 4-7.
When the bottom of hold down gag 4 is subject to oppressing, first spring 4-9 and the second spring 4-10 is compressed, the framework be made up of upper plate body 4-1, lower body 4-6, upper branch arm 4-3 and lower branch arm 4-5 becomes flattening, and this hold down gag 4 can the power transmission line of self-adaptation different-diameter size.
In the present embodiment, in order to promote the fixed effect of power transmission line, multiple tracks fin can be set on the cell wall of the groove of cushion block 9.
In the present embodiment, the indicator 13 indicated the malfunction of current power transmission line is also installed in the bottom of lower box body 8.Indicator 13 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 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. 3 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 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 is between the groove and the groove of cushion block 9 of liner 4-8, 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.
