Description

Technical Field

[0001] This invention relates to the field of power distribution network technology, and in particular to a grounding fault diagnosis device for power distribution networks. Background Technology

[0002] With the rapid development of power systems, the safe and stable operation of distribution networks is crucial for power supply. Ground faults are one of the most common types of faults in distribution networks, which can lead to equipment damage, power outages, and even personal injury accidents. Therefore, rapid and accurate diagnosis of ground faults is of great significance for ensuring power grid reliability and maintenance efficiency.

[0003] Traditional grounding fault diagnosis methods typically rely on manual inspection or simple testing equipment, resulting in low efficiency, insufficient accuracy, and poor adaptability. For example, existing fault detection devices often cannot flexibly adapt to the grounding detection needs of different terrains or complex environments, and lack convenience and stability when fixing wires or adjusting detection height. In addition, the installation and adjustment process of some devices is cumbersome, making it difficult to achieve rapid deployment and precise positioning, which affects the timeliness and accuracy of fault diagnosis. Summary of the Invention

[0004] The purpose of this invention is to address the problems of low efficiency, insufficient accuracy, and poor adaptability inherent in existing technologies that rely on manual inspection or simple testing equipment. For example, existing fault detection devices often cannot flexibly adapt to the grounding detection needs of different terrains or complex environments, and lack convenience and stability when fixing wires or adjusting the detection height. Furthermore, the installation and adjustment processes of some devices are cumbersome, making rapid deployment and precise positioning difficult, thus affecting the timeliness and accuracy of fault diagnosis.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a grounding fault diagnosis device for a power distribution network, comprising: a block, a hollow rod movably embedded inside the block, a thin rod fixedly installed on one side of the block, a slider movably fitted on the outer surface of the thin rod, a plurality of upper semicircular blocks rotatably connected to one side of the slider via a rotating rod, a hollow block rotatably connected to one side of each of the plurality of upper semicircular blocks via a rotating rod, a telescopic block movably embedded inside each of the plurality of hollow blocks, a hole opened at the top of each of the hollow blocks, a second limiting block fixedly installed at the top of each of the hollow blocks, a pull rod movably embedded inside each of the plurality of second limiting blocks, and a circular block fixedly installed at the bottom of each of the plurality of pull rods.

[0006] The technical effect of adopting the above-mentioned further solution is: rotating the threaded rod two moves inside the protrusion on the front side of the telescopic block. At this time, the threaded rod two is embedded in the inside of the limiting hole. Then, rotating the threaded rod three is embedded in the inside of the round hole. At this time, the threaded rod two is limited. At this time, the upper half-circle block and the lower half-circle block are connected and clamped on the outer surface of the wire for fixation.

[0007] In a preferred embodiment, a spring 2 is fixedly installed on the top of each of the plurality of circular blocks, the top of each of the plurality of spring 2 is fixedly installed on the bottom of each of the plurality of limiting blocks 2, a locking rod 2 is fixedly connected to the bottom of each of the plurality of circular blocks, the locking rod 2 is movably embedded in the interior of each of the plurality of holes, a plurality of lower semi-circular blocks are fixedly installed on one side of the slider, a plurality of limiting holes are opened on one side of each of the plurality of lower semi-circular blocks, and a threaded rod 3 is movably embedded inside each of the plurality of lower semi-circular blocks.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: when the pull rod is pulled, the round block moves upward. At this time, the second locking rod disengages from the hole above the telescopic block. When the telescopic block is pulled, it moves inside the hollow block. At this time, under the elastic limit of the second spring, the round block is attached to the surface of the second limiting block, and the second locking rod is locked in the hole of the telescopic block, thereby limiting the telescopic block.

[0009] In a preferred embodiment, threaded rod 2 is movably embedded on one side of each of the plurality of lower semicircular blocks, and the plurality of threaded rod 2 are movably embedded inside the plurality of limiting holes. The outer surface of each of the plurality of threaded rod 2 is provided with a circular hole, and the plurality of threaded rod 3 are movably embedded inside the plurality of circular holes. The outer surface of the hollow rod is provided with a plurality of locking holes, and a telescopic rod is movably embedded inside the hollow rod. A rectangular plate is fixedly installed at the bottom of the telescopic rod.

[0010] The technical effect of adopting the above-mentioned further solution is that: the threaded rod three is inserted into the inside of the circular hole, and the threaded rod two is limited at this time. At this time, the upper half-circle block and the lower half-circle block are connected and clamped on the outer surface of the wire for fixation.

[0011] In a preferred embodiment, an electric push rod is fixedly installed at the bottom of the rectangular plate, a movable plate is fixedly installed at the bottom of the electric push rod, a motor is fixedly installed at the top of the movable plate, a rotating rod is fixedly installed at the output end of the motor, a drilling rod is fixedly installed at the output end of the rotating rod, a fault detector is fixedly installed at the bottom of the rectangular plate, two dampers are fixedly installed on the inner wall of the telescopic rod, two springs are fixedly installed on the inner wall of the telescopic rod, and a locking rod is fixedly installed at one end of each of the two springs.

[0012] The technical effect of adopting the above-mentioned further solution is that pressing the first locking rod causes the first spring and the damper to move inward. At this time, the first locking rod slides on the inner wall of the hollow rod and then locks into any locking hole, so that the height of the rectangular plate can be adjusted.

[0013] In a preferred embodiment, both of the two locking rods are movably embedded in two of the locking holes. An L-shaped block is fixedly installed on the outer surface of the block. A threaded rod is movably embedded inside the L-shaped block. The threaded rod is movably embedded inside one of the locking holes. A limit block is fixedly installed on the top of the hollow rod. A data cable is fixedly installed on the outer surface of the fault detector. One end of the data cable is fixedly installed on the outer surface of the movable plate.

[0014] The technical effect of adopting the above-mentioned further solution is that it is used to limit the telescopic rod, thereby making the distance between the drilling rod and the ground closer, which facilitates detection.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. In this embodiment of the invention, the lower semicircular block is located on the lower surface of the wire, and the upper semicircular block is located on the upper surface of the wire. At this time, the upper semicircular block rotates around the slider as the center. At this time, the pull rod is pulled to move the circular block upward. At this time, the second locking rod disengages from the hole above the telescopic block. At this time, the telescopic block is pulled to move inside the hollow block. At this time, under the elastic limit of the second spring, the circular block is made to fit against the surface of the second limiting block. The second locking rod is locked in the hole of the telescopic block, thereby limiting the telescopic block. Then, the second threaded rod is rotated to move inside the protrusion on the front side of the telescopic block. At this time, the second threaded rod is embedded in the inside of the limiting hole. Then, the third threaded rod is rotated to be embedded in the inside of the circular hole. At this time, the second threaded rod is limited. At this time, the upper semicircular block and the lower semicircular block are connected and clamped on the outer surface of the wire for fixation. The thin rod is embedded in the inside of the slider and can move.

[0017] 2. In this embodiment of the invention, the electric push rod is started by an external power source. At this time, the electric push rod drives the movable plate to move downward. At this time, the motor drives the rotating rod to rotate, and the rotating rod drives the drilling rod to rotate. At this time, the drilling rod rotates while moving downward, and can drill into the ground to make contact with the grounding wire. At this time, the grounding wire is detected by a fault detector, and the data is transmitted to the inside of the fault detector through a data line. It should be noted that the length of the telescopic rod can be determined according to the actual situation.

[0018] 3. In this embodiment of the invention, the hollow rod moves up and down inside the block. At this time, pressing the locking rod causes the spring and damper to move inward. The locking rod slides on the inner wall of the hollow rod and then locks into any locking hole, so that the height of the rectangular plate can be adjusted. Attached Figure Description

At this time, under the elastic limit of the spring 125, the circular block 126 is attached to the surface of the limiting block 123. The locking rod 127 is locked in the hole of the telescopic block 128, thereby limiting the telescopic block 128.

Pressing the locking rod 108 causes the springs 109 and the dampers 110 to move inward. At this time, the locking rod 108 slides on the inner wall of the hollow rod 102 and then locks into any locking hole 106, so that the height of the rectangular plate 111 can be adjusted.

[0034] like Figures 1 to 8 As shown, in one embodiment, two locking rods 108 are movably embedded in two locking holes 106.

One end of the data cable 118 is fixedly installed on the outer surface of the movable plate 113 for limiting the telescopic rod 107, thereby bringing the drilling rod 116 closer to the ground for easier detection.

[0035] Working principle: In use, the lower semicircular block 131 is placed on the lower surface of the wire, and the upper semicircular block 121 is placed on the upper surface of the wire. The upper semicircular block 121 rotates around the slider 120. Pulling the lever 124 moves the circular block 126 upwards.

Under the elastic limit of the spring 125, the circular block 126... The second locking rod 127 is attached to the surface of the limiting block 123 and is locked in the hole of the telescopic block 128, thereby limiting the telescopic block 128. Then, the threaded rod 129 is rotated and moves inside the protrusion on the front side of the telescopic block 128. At this time, the threaded rod 129 is embedded in the limiting hole 132. Then, the threaded rod 133 is rotated and embedded in the round hole 130, thus limiting the threaded rod 129. At this time, the upper semicircular block 121 and the lower semicircular block 131 are connected and clamped on the outer surface of the wire. The surface is fixed, and the thin rod 119 is embedded in the slider 120 and can move. At this time, the hollow rod 102 moves up and down inside the block 101. Pressing the locking rod 108 causes the spring 109 and the damper 110 to move inward. The locking rod 108 slides on the inner wall of the hollow rod 102 and then locks into any locking hole 106, so that the height of the rectangular plate 111 can be adjusted.
