Fig. 2 is this practical new use procedure schematic diagram;
The specific purpose tool structural representation that Fig. 3 is used for handling the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Fig. 1 Fig. 2, first ring lobe 1 and the second ring lobe 2 are semicircle, first ring lobe 1 is provided with semi-circular recesses 16, the second ring lobe 2 is provided with semi-circular recesses 14, groove 14, current measurement coil is installed in 16, claim again Luo-coil, in first ring lobe 1 inside, leave space, the inside is provided with metering circuit plate 15(metering circuit plate and also can be arranged on the inside of the second ring lobe 2), metering circuit plate 15 is electrically connected to current measurement coil, for surveyed current data is sent, wireless data sending module is also installed on circuit board 15, can send data to DRS nearby on ground, DRS can be passed to server by remote data again.Current measurement coil and metering circuit plate 15 and wireless data sending module are the known mature technology of electronic engineering technician.First ring lobe 1 and the second ring lobe 2 are at one end hinged by hinge axis 3, at the other end of the second ring lobe 2, dig and have a sheet groove 5, prop up in sheet groove 5 and be hinged with and prop up a sheet 4, can will prop up that sheet 4 rotates a sheet groove 5 and to first ring lobe 1, (also can be located on first ring lobe 1 propping up sheet groove and a sheet, thereby will prop up sheet, prop up on the second ring lobe).
At first ring lobe 1 and the semicircular circle centre position of the second ring lobe 2, be respectively equipped with breach, two breach are relatively to forming a complete breach 7, breach 7 is semicircle below the center of circle, above the center of circle, be that the center of circle is inverted v-shaped breach to a side who props up sheet 4, the first ring lobe 1 and second that is distributed in of whole breach 7 symmetries encircles on lobe 2.In use, high voltage overhead lines 60 is stuck in breach 7, a part of surface of pole line 60 and semicircle breach fit, and increase the fastness of blocking, and another part surface is blocked by inverted v-shaped breach.When needs take off electricity measurer, thereby 60 pairs of inverted v-shaped breach of pole line produce shearing force, first ring lobe 1 and the second ring lobe 2 are separated, pole line 60 gets final product slippage out.
On two sides of first ring lobe 1 and the second ring lobe 2, be provided with spring 12 and spring 13, each both ends of the spring is connected with two ring lobes respectively, can make two ring lobes produce the power being combined.The lengthwise position of spring is positioned in the middle of the semicircle center of circle of ring lobe and a sheet 4, like this when pole line 60 is stuck in breach 7 when interior, force spring 12,13 bendings, the opposition of generation increases the friction force of pole line 60 and spring 12,13, is conducive to prevent that electricity measurer from rotating on pole line 60.
On first ring lobe 1, dig and have slot 8, slot 8 tops are connected with jack 10, and jack 10 can be made blind hole or through hole, below slot, be connected with traverse furrow 11, the opening part 6 of traverse furrow 11 be positioned at jack 10 under.The opening 9 of slot 8 is located on the semicircle outward flange of first ring lobe 1.Slot 8, jack 10 and traverse furrow 11 also can be located on the second ring lobe 2.
Fig. 3 is the structural representation of handling electricity measurer specific purpose tool used.This instrument has locating rack 50, plug 54, pick up the ears 51 and insulation handle 52.Electricity measurer is installed to be fallen on pole line 60 to make, first with a sheet 4, at first ring lobe 1 and the second ring lobe 2, separate a gap, then with hand, the plug of instrument 54 is inserted to the jack 10 of electricity measurer, pick up the ears in 51 insertion traverse furrows 11, hand-held insulation handle 52 is upwards elected, locating rack 50 is touched to pole line 60, then make a pole line 60 extruding sheet 4, can with breach 7, block pole line 60 smoothly.Then can carry out amperometric determination.When needs take off electricity measurer, hand-held insulation handle 52 slips into slot 8 by plug 54 from opening 9, then upwards insert jack 10, then the handle 52 that will insulate rotates, and makes to pick up the ears to proceed in traverse furrow 11, and instrument coordinates complete with electricity measurer, then haul insulation handle 52, acting force can be passed on electricity measurer, pole line 60 is rived inverted v-shaped breach from electricity measurer slippage out, thereby completes the work of dismounting electricity measurer.
