Description

Technical Field

[0001] This application relates to the technical field of cable breakage detection, and specifically to a distribution network cable breakage detection device. Background Art

[0002] Distribution network cables refer to the wires used to distribute electric energy in the power system. Distribution network cables are usually made of metals such as copper or aluminum, and have good electrical conductivity and thermal conductivity; the main function of distribution network cables is to transmit electric energy from the power plant to users, providing stable and reliable power supply for users. Distribution network cables usually include two types: overhead lines and cables;

[0003] After the existing cables are processed, it is necessary to detect their breakage to avoid the possible leakage of electricity caused by the broken cables, which may lead to electric shock accidents and endanger personal safety. At the same time, ensure the overall stable operation of the distribution network and avoid affecting the normal operation of the entire power network due to local cable problems.

[0004] For example, the patent with the publication number CN220933110U specifically discloses a power cable breakage positioning device, including a base, a mounting frame, a high-voltage detector, and the settings of a first U-shaped frame, a winding assembly, a driving motor, a winding roller, and a traction assembly. Thus, it is possible to avoid the cable being concentrated and wound on a certain section of the winding roller, promote the uniform winding of the cable, and there is no need for manual traction with tools, which is relatively convenient to use, and it is also convenient to disassemble and install the winding roller.

[0005] When the above-mentioned patent cable breakage detection device is in use, since the cable before detection is not surface-cleaned, the dirt and dust attached to the cable surface are likely to cover up the fine breaks and cracks, resulting in detection omission problems. Therefore, it is necessary to initially clean the cable so that fine breaks, cracks or other abnormalities are more easily detected. Therefore, it is necessary to design a distribution network cable breakage detection device to solve the above problems.

[0026] On the detection table 1, on one side of the DC power supply 301, a winding component 4 is installed.

[0029] On the U-shaped frame 405, two sets of limiting rods (not marked in the figure) are fixedly installed. The limiting rods movably penetrate through the sliding column 409.

[0030] The second pulley is adapted to rotate with the output end of the motor 402 so as to drive the first pulley 407 to rotate, thereby driving the lead screw 406 to rotate, and further driving the sliding column 409 to linearly move on the lead screw 406, and enabling the distribution network cable to be evenly wound around the winding roller 403;

[0031] A cleaning assembly 5 is connected between the two sets of mounting brackets 201. The cleaning assembly 5 is used for surface cleaning of the distribution network cable. The cleaning assembly 5 includes a fixed seat 501 fixedly installed on the two sets of mounting brackets 201.

[0032] A first cleaning semi-ring 504 is fixedly installed on the slider 503. A second cleaning semi-ring 505 is rotatably installed on the first cleaning semi-ring 504. A bolt 506 is connected between the first cleaning semi-ring 504 and the second cleaning semi-ring 505. The bolt 506 is adapted to fix the second cleaning semi-ring 505 on the first cleaning semi-ring 504;

[0033] Cleaning blocks 507 are snap-fitted on both the first cleaning semi-ring 504 and the second cleaning semi-ring 505. A cleaning part is provided at the contact position between the cleaning block 507 and the distribution network cable. The cleaning part is a cleaning sponge. A fastening mechanism is installed on the first cleaning semi-ring 504 and the second cleaning semi-ring 505. The fastening mechanism is adapted to fix the cleaning block 507 on the first cleaning semi-ring 504 and the second cleaning semi-ring 505;

[0034] The fastening mechanism includes a connecting rod 508 fixedly installed on the first cleaning semi-ring 504 and the second cleaning semi-ring 505. A screw rod 509 is threadedly connected to the connecting rod 508. At the same time, a screw groove adapted to the screw rod 509 is opened on the connecting rod 508. A locking block 511 is fixedly installed at one end of the screw rod 509. At the same time, a buckle hole 512 adapted to the size of the locking block 511 is opened on the cleaning block 507. The screw rod 509 is adapted to rotate and press the cleaning block 507 against the first cleaning semi-ring 504 and the second cleaning semi-ring 505;

[0035] A rotating rod 510 is fixedly installed on the screw rod 509. The rotating rod 510 facilitates the rotation of the screw rod 509;

[0036] Working principle:

[0037] When it is necessary to detect the surface damage of the distribution network cable, the user passes the distribution network cable through between the first cleaning semi-ring 504 and the second cleaning semi-ring 505, and then passes the free end of the distribution network cable through between the two groups of flattening rollers 202. When the distribution network cable is pulled, the bent distribution network cable will be straightened. Then, after the user controls the DC power supply 301 to be energized, the free end of the distribution network cable is passed through the brush 303. Then, the user passes the free end of the distribution network cable into the traction ring 410 and winds it around the winding roller 403;

[0038] Subsequently, the winding assembly 4 is started to work. Thus, the second pulley rotates with the output end of the motor 402 to drive the first pulley 407 to rotate, thereby driving the lead screw 406 to rotate, and further driving the sliding column 409 to linearly move on the lead screw 406, and making the distribution network cable evenly wound around the winding roller 403. When the distribution network cable is wound, the cleaning blocks 507 on the first cleaning semi-ring 504 and the second cleaning semi-ring 505 can clean the dirt on the surface of the distribution network cable;

[0039] After cleaning, the distribution network cable will continuously move to the left through the brush 303. The DC power supply 301 applies a voltage to the insulation outer skin of the distribution network cable at a fixed frequency. If there is a breakage problem in the insulation layer of the distribution network cable, the voltage will break down the insulation layer, causing a potential difference between the conductor and the ground, and thus generating a current. The ammeter 305 will show a value, and the ammeter 305 will transmit the current signal to the control switch 304. After receiving the signal, the control switch 304 will turn off the motor 402 and the DC power supply 301, and then the staff will check the cable insulation layer near the brush 303;

[0040] When the cleaning blocks 507 on the first cleaning semi-ring 504 and the second cleaning semi-ring 505 are used for a long time and their cleaning effect is poor, by holding the rotating rod 510 and rotating the screw 509, the locking block 511 is moved away from the buckle hole 512, and then by loosening the bolt 506 and rotating the second cleaning semi-ring 505, it is convenient to disassemble and replace the cleaning blocks 507 on the first cleaning semi-ring 504 and the second cleaning semi-ring 505.

[0041] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
