[0002] In the field of power engineering, wire connection is a key link to ensure the stability and safety of power transmission. With the continuous growth of power demand and the continuous advancement of power grid construction, from large power stations to urban power distribution networks, to millions of households of electricity facilities, a large number of wire connection operations are needed, and some connection operations require complex procedures, such as "hinged + tin dipping + insulation tape coating" process, which not only needs to melt tin on site, but also has high temperature and high heat safety hazards, and requires high skills of the operator.

[0026] The working principle of the present application is as follows: the wire passes through two limiting semicircular plates 282, at this time the wire is located below the limiting roller 287, at this time the micro pumping device is started, the micro pumping device will extract hydraulic oil from the sealed shell 283, and then pump the hydraulic oil into the hydraulic telescopic rod 242, the hydraulic oil gradually in the hydraulic telescopic rod 242 will make it elongate, at the same time the U-shaped block 286 will move downward with the loss of hydraulic oil, the U-shaped block 286 will drive the limiting roller 287 to move downward at the same time, until the limiting roller 287 contacts the surface of the wire and limits the wire through the upper end of the sealed shell 283 (when the device is in the initial state, the limiting roller 287 is located above the limiting semicircular plate 282, and cannot limit the wire), at this time the two limiting semicircular plates 282 will also limit the wire under the action of elastic connection, at this time the wire can only move into the device, and cannot be shortened back (because the connecting part of the limiting roller 287 and the limiting rod 285 adopts a one-way bearing, so that the limiting roller 287 can only rotate in one direction, when the worker stretches the wire to the direction of the device, the limiting roller 287 in contact with the wire will rotate, and when the worker pulls the wire in the opposite direction, the limiting roller 287 limited by the one-way bearing cannot rotate, and the limiting roller 287 and the surface of the wire have large friction, so that the wire can only be stretched into the device and cannot be retracted), and a certain force is needed to stretch the wire into the device, under the condition that the wire will not be broken, the length of the wire inserted into the device is moderate, which is convenient for subsequent connection of the wire, and the wire that has been connected will not loosen outward during the subsequent dragging or daily use of the wire, reducing the possibility of short circuit at the connection part; After the wire is pulled to the appropriate length, the micro-pumping device is started again to pump hydraulic oil from the hydraulic telescopic rod 242 into the sealed shell 283. The hydraulic oil entering the sealed shell 283 pushes the U-shaped block 286 and the limiting roller 287 to move upwards until the bottom of the U-shaped block 286 contacts the lower end of the limiting rod 285. The limiting rod 285 limits the upward movement of the U-shaped block 286, and the hydraulic telescopic rod 242 gradually shortens as the hydraulic oil flows. In this process, the movable block 243 is moved downwards, pushing the connecting block 244 on the same side to move towards the connecting head 25 (the end surfaces of the movable block 243 and the connecting block 244 are provided with the same inclined surface, and when the movable block 243 moves downwards, it pushes the connecting block 244 to move through the inclined surface, and because the inclined surface is smooth, the movable block 243 does not generate a large friction force when pushing the connecting block 244 to move), and the connecting block 244 moves the energized ring 245 at the same time until the energized ring 245 and the connecting head 25 clamp the wire. The connecting head 25 is composed of an insulating layer and a metal layer, and when the energized ring 245 and the metal layer of the connecting head 25 contact two wires at the same time, the two wires can be connected. The upward movement of the limiting roller 287 allows the wires to be connected at an appropriate height (when the limiting roller 287 is at a lower position, it presses the area of the wire in contact downwards, causing the two wire ports for connection to be raised upwards, which is not conducive to the connection of the two wires). Although the two limiting semicircular plates 282 clamp and fix the wire, the connection of the wire may not be tight enough, which may cause the contact resistance of the connection of the two wires to increase, thereby increasing the temperature of the connection, and further increasing the surface temperature of the thermistor 33 in contact with the connecting head 25. According to the characteristics of the thermistor 33, when the surface temperature of the thermistor 33 increases, the resistance value of the area where the temperature increases will increase (the thermistor 33 in the device has PTC characteristics, usually made of barium titanate-based ceramic and other semiconductor materials. When the temperature rises to the critical phase transition temperature of the material, a ferroelectric-paraelectric phase transition occurs inside the thermistor 33, the polarization state of the crystal grain changes, causing the crystal boundary barrier to rise significantly. The rise of the crystal boundary barrier greatly hinders the migration of charge carriers across the crystal boundary, causing the number of electrons passing through in a unit of time to decrease sharply, which macroscopically appears as a non-linear sharp increase in resistance value). The heat dissipation hole 32 can ensure that the thermistor 33 does not overheat due to insufficient heat dissipation. The detection device 43 can start the two electric telescopic rods 34 to drive the detection shell 41 to move regularly (the detection device 43 has a PLC controller, a current detection module and a power module, the PLC controller controls the electrical elements in the device, the power module supplies power to the detection metal sheet 49, and the current detection module detects the current intensity through the thermistor 33, and then feeds back the temperature change of the thermistor 33, so as to know whether the wire above is in poor contact state), the components in the detection shell 41 can detect the temperature of the thermistor 33, that is, whether the resistance of the wire connection increases, and the adjustment can be made before complete short circuit, in order to ensure the stability of the wire connection, the electric telescopic rod 34 can be started once a week (the contact state of the wire is detected once a week), the transmission gear 46 is in meshing state with the gear plate 35, so that it can drive the connecting rod 45 to rotate during movement, so that the two reciprocating lead screws 44 rotate at the same time, and the two reciprocating lead screws 44 and the hollow column 47 are oppositely arranged, when the two reciprocating lead screws 44 rotate in the same direction, the two hollow columns 47 move in opposite directions, that is, when the electric telescopic rod 34 shortens to drive the detection shell 41 to move, the two hollow columns 47 first move away from each other until the two detection metal sheets 49 respectively contact the surfaces of the thermistors 33 on the same side; The power module in the detection device 43 supplies power to the detection metal sheet 49 to form a complete circuit, and the current detection module detects the current in the circuit, it should be noted that the two thermistors 33 have a certain distance, when the detection shell 41 is between the two thermistors 33, the two hollow columns 47 move away from each other, when the detection metal sheet 49 contacts the thermistor 33, the two hollow columns 47 move towards each other, instead of keeping the detection metal sheet 49 in a fixed position to detect the resistance of the thermistor 33, which can prevent the detection metal sheet 49 from deforming due to friction when contacting different thermistors 33, and the electric telescopic rod 34 shortens to drive the detection shell 41 to move, the detection device 43 can detect the temperature rise of the thermistor 33, that is, the resistance of the wire connection at the same position increases; Then the problem of the wire is powered off, and start the micro-pumping device, the hydraulic telescopic rod 242 reciprocating extension, the U-shaped block 286 will also reciprocating up and down, the use of up and down movement of the limiting roller 287 slightly touch the wire, the position of the wire is adjusted, the energized ring 245 can also constantly adjust the position of the wire port, the reciprocating distance of the U-shaped block 286 and the energized ring 245 is only about two-thirds of the installation time, instead of reciprocating installation of the wire, so that the limiting roller 287 and the energized ring 245 in the process of reciprocating can improve the contact of the wire, prevent more serious problems such as complete short circuit, and then restore power to the wire, at this time the reverse start electric telescopic rod 34 makes it elongation, the detection metal sheet 49 always contact the thermistor 33 which detects the temperature rise before, and stay for a period of time, if the thermistor 33 still appears temperature rise in the case of wire power supply, will automatically alarm to make the staff to overhaul, if the thermistor 33 no longer appears temperature rise, start the electric telescopic rod 34 to reset the detection shell 41 and wait for the next detection.

[0027] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
