The working principle is as follows:
the first step is as follows: through the design of pressing from both sides device 1, when using the device, at first put into shell device 2 with the cable that needs the control position and monitor, press from both sides the design that gets device 1 and be exactly the cable that is used for pressing from both sides the required detection site both ends, through the design of column casing 103, after putting into lower clamp 107 and upper clamp 101 with the cable at both ends, because pass through spring coupling between column casing 103 and the clamp post 104, thereby extrusion clamp 105 can promote the cable and press from both sides 101 and lower clamp 107 inside and lean on left rigidity, through the design of extrusion clamp 105, thereby make the cable of different diameters size all can be pressed from both sides the stable clamp of getting of device 1 and press from both sides, great improvement the application scope of device.
The second step is that: through the design of the connecting device 3, after the cable is fixed by the clamping device 1, the handle 312 is rotated from the outside, the first connecting column 301 can be driven to rotate, the first connecting columns 301 at two ends are connected through the second connecting column 311, so that the first connecting columns 301 at two ends rotate simultaneously, the spring plate 306 can be gradually pushed to convey by rotating the first connecting columns 301, when the handle 312 rotates clockwise, the head knife 309 can gradually approach towards the cable under the driving of the spring plate 306, then the head knife 309 can be inserted into the sheath of the cable, the handle 312 continues to rotate clockwise, so that the head knife 309 drives the spring plate 306 to enter the inside of the cable, then the handle 312 rotates anticlockwise, so that the spring plate 306 is inserted into the inside of the cable and wrapped inside of the cable, so that the inner side wire 307 is connected with the cable, thereby completing the connecting work of the device, the operation is simple and convenient.
The third step: after the connection is completed, the line connected with the first electric wire 207 and the second electric wire 208 is connected in parallel with the monitored line, when the cable loop generates heat, the heat emitted by the cable is transferred to the inside of the heat cylinder 418 through the heat conduction column 417, so that the heat at the two ends of the heat cylinder 418 is different, the heat at the rear end of the heat cylinder 418 can expand the air at the rear end of the heat cylinder 418, so as to push the piston 420 to move forward in the inside of the heat cylinder 418, so as to drive the sliding sheet 404 to move forward, so that the resistance wire 406 is connected to the line, so that a part of the current passes through the line of the first electric wire 207 and the second electric wire 208, after the shunting, the heating pressure of the cable is reduced, at this time, the air at the rear end of the heat cylinder 418 recovers the temperature, and as the air in the heat cylinder 418 recovers the original state, the piston 420 gradually recovers to the original position, therefore, the design of the adjusting device 4 plays the roles of automatic adjustment and automatic recovery for cable heating, and the automatic performance of the device is greatly improved.
The fourth step: when a line of the first electric wire 207 and the second electric wire 208 passes through a current, due to the existence of the fan 412 and the high-resistance alarm 411, the fan 412 and the high-resistance alarm 411 can be shunted, due to the large resistance in the high-resistance alarm 411, when the line of the first electric wire 207 and the second electric wire 208 is shunted, the current passing through the high-resistance alarm 411 is not triggered to alarm under the condition that the current passing through the high-resistance alarm 411 is weak, at this time, the alarm is not needed to be given, when the cable generates heat seriously, the sliding sheet 404 is driven by the adjusting column two 422 to be positioned at the position close to the front side of the resistance wire 406, at this time, most of the current passes through the line of the first electric wire 207 and the second electric wire 208, because the current of the line of the first electric wire 207 and the second electric wire 208 is too large, the current obtained by the line of the high-resistance alarm 411 is larger, at this time, the high-resistance alarm 411 is triggered to alarm to give an alarm, thereby the safety of effectual protection circuit, great improvement device's safety in utilization.
The fifth step: through the design of the first electric wire 207 and the second electric wire 208 in a shunting manner, firstly, the heating of the cable can be regulated to a certain extent, and secondly, due to the existence of the first electric wire 207 and the second electric wire 208, time is strived for between alarming and cable repairing, so that the danger caused by overheating of the cable is avoided, and the use safety of the device is ensured.
And a sixth step: through the existence of guard post 305, guard post 305 supports spring plate 306 in inside, at first provide the basis of support for spring plate 306 when spring plate 306 gets into the cable, thereby can help among the more light entering cable of spring plate 306, secondly guard post 305's existence, when the taut cable of spring plate 306 gyration, guard post 305 has effectually separated the distance between the spring plate 306, thereby help the inside embedding of spring plate 306 to connect medial line 307 and carry out effectual heat dissipation, great improvement the working capacity of device, the scientificity of device work has been improved.
