After the grounding fault of the line occurs, the line needs to be detected, the power of the line is first determined, then one end of three red signal lines is connected to a hook clamp rod, the other end of the signal line is connected to one end of a positioning equipment host, the host is grounded, a signal collector and a signal receiver are turned on, normal use is determined, the signal collector is connected to a telescopic rod, and the three hook clamp rods are hung on three guide lines of the fault line. The host is started, signals are injected into the fault line, three-phase currents are detected on both sides of the injection point, and the fault point is judged according to the three-phase currents. However, the detection point needs to be changed frequently during use, the signal line needs to be moved back and forth, and the signal line needs to be unfolded during use because the signal line is long and generally wound. The signal line is prone to loosen and cause disorder or winding in one place, which is very inconvenient to use. Meanwhile, it is very inconvenient to wind up, greatly wastes time cost, and also delays work efficiency. Therefore, the grounding fault ranging online detection device is proposed to solve the above problems. SUMMARY

[0003] The application aims to provide a grounding fault ranging online detection device to solve the problems in the background.

[0004] To achieve the above-mentioned purpose, the application provides the following technical scheme.

[0014] As an optional solution of the online detection device for grounding fault ranging, the inside of the hollow cylinder is slidably connected with a rotating rod, and the rotating rod is arranged in a T-shaped manner.

[0015] The existing device needs to change the detection point frequently and needs to move the signal line back and forth. Since it is an overhead line, the signal line needs to be long. Generally, the signal line is wound. When in use, the signal line needs to be unfolded. The signal line is prone to be loose and tangled, which is very inconvenient to use. At the same time, it is very inconvenient to wind, which greatly wastes time cost and delays work efficiency. When the device is in use, the sliding frame is arranged on the front side of the online detection device. When in use, the cable is connected to one end of the hooking rod. The hooking rod is directly pulled to drive the winding shaft to rotate, so that the cable can be conveniently unwound. When winding, the hollow cylinder and the rotating arm are rotated by rotating the rotating rod, so that the winding shaft is rotated, and the cable is conveniently stored. This arrangement not only ensures that the cable is not easily loose and tangled, but also makes winding convenient when changing the detection site, greatly saving time cost and ensuring the efficiency of detection. To ensure the winding efficiency of the cable, the rotating rod is slid outward, so that one end of the rotating rod is displaced inside the hollow cylinder. The rotating rod can be directly rotated to achieve the purpose of winding the cable. When not in use, one side of the rotating rod is located inside the limiting hole, and the first magnetic ring and the second magnetic ring cooperate to avoid the rotating rod from being separated from the limiting hole to cause the sliding frame to be unable to smoothly slide into the inside of the online detection device.

[0016] As an optional scheme of the online detection device for grounding fault distance measurement, the rear side plate of the sliding frame is slidably connected with three groups of transverse rods, one end of the transverse rod is fixedly connected with the online detection equipment, and the other end of the transverse rod is fixedly connected with a limiting frame.

[0020] As an optional scheme of the online detection device for grounding fault distance measurement, the rear side plate of the sliding frame is slidably connected with three groups of transverse rods, one end of the transverse rod is fixedly connected with the online detection equipment, and the other end of the transverse rod is fixedly connected with a limiting frame.

[0022] As an optional scheme of the online detection device for grounding fault distance measurement, the rear side plate of the sliding frame is slidably connected with three groups of transverse rods, one end of the transverse rod is fixedly connected with the online detection equipment, and the other end of the transverse rod is fixedly connected with a limiting frame.

[0023] When the cable is used, the spring is pressed against the sliding plate, so that the sliding rod drives the rotating column and the rotating sleeve to move, the rotating sleeve is in close contact with the cable, at this time, the cable can be effectively prevented from being loosened, the winding of the cable can be ensured to be tight, and when the sliding frame slides into the online detection equipment, the limiting frame on one side of the transverse rod cooperates with the gear on one side of the rotating column, at this time, the rotating sleeve can be prevented from rotating, the purpose of supporting the cable can be achieved, and the cable can be prevented from being loosened.

[0024] Compared with the prior art, the online detection device for grounding fault distance measurement has the following beneficial effects:

[0025] The application is used for setting the sliding frame on the front side of the online detection equipment, and the cable is connected to one end of the hook clamp rod during use, so that the hook clamp rod can drive the winding shaft to rotate by being directly pulled, thereby facilitating the cable to be unwound, and when the cable is wound, the hollow cylinder and the rotating arm can be driven to rotate by rotating the rotating rod, so that the winding shaft rotates, thereby facilitating the cable to be stored, which not only ensures that the cable is not easily loosened and wound, but also facilitates winding when the detection site is changed, greatly saves time cost, and ensures the detection efficiency.

[0026] In order to ensure the winding efficiency of the cable, the rotating rod is slid outward, so that one end of the rotating rod is displaced inside the hollow cylinder, and the purpose of winding the cable can be achieved by directly rotating the rotating rod. When not in use, one side of the rotating rod is located inside the limiting hole, and the first magnetic ring and the second magnetic ring cooperate to avoid the rotating rod from being separated from the limiting hole to cause the sliding frame to be unable to smoothly slide into the online detection equipment.

[0027] When the cable is used, the spring presses the sliding plate, so that the sliding rod drives the rotating column and the rotating sleeve to move, and the rotating sleeve is in close contact with the cable, so that the cable can be effectively prevented from being loosened, and the winding of the cable can be ensured to be tight.

[0028] When the sliding frame slides into the online detection equipment, the limiting frame on one side of the transverse rod cooperates with the gear on one side of the rotating column, so that the rotating sleeve can be prevented from rotating, thereby effectively supporting the cable and preventing it from loosening.

DETAILED DESCRIPTION

[0037] Embodiment 1: see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides a technical solution:

[0038] A grounding fault ranging online detection device, comprising online detection equipment 1, inner buckle cover 2 and cushion block 3;

[0039] The bottom of the online detection equipment 1 is provided with a plurality of groups of cushion blocks 3 for supporting the online detection equipment 1;

[0040] The top of the online detection equipment 1 is provided with an operation panel 4;

[0041] The side of the online detection equipment 1 is further provided with an inner buckle cover 2 for shielding the operation panel 4;

[0042] The front side of the online detection equipment 1 is provided with a cable winding assembly 5 for placing a cable, and the inside of the cable winding assembly 5 is provided with three groups of anti-loose mechanisms 6;

[0043] The cable winding assembly 5 comprises a sliding frame 501, a side groove 502 and a limiting hole 503, the side of the sliding frame 501 is provided with a side groove 502, and the inside of the side groove 502 is provided with a plurality of limiting holes 503, the central position of the side groove 502 is rotatably connected with a winding shaft 504, one side of the winding shaft 504 is fixedly connected with a rotating arm 505, and the other end of the rotating arm 505 is fixedly connected with a hollow cylinder 507;

[0044] The outside of the winding shaft 504 is rotatably connected with a storage rack 510, the inside of the storage rack 510 is provided with a cable 511 wound outside the winding shaft 504, and the outside of the storage rack 510 is further rotatably connected with a support rack 512, and the bottom of the support rack 512 is fixedly connected with the sliding frame 501;

[0045] Each side of the aforementioned support frame 512 is fixedly connected with an anti-loosening mechanism 6.

[0046] The hollow cylinder 507 is slidably connected to a rotating rod 506, which is I-shaped.

[0047] A first magnetic ring 508 is installed on one side of the interior of the hollow cylinder 507, and a second magnetic ring 509 is fixedly connected to the rotating rod 506 on one side of the first magnetic ring 508. The opposite end faces of the first magnetic ring 508 and the second magnetic ring 509 are arranged with opposite poles.

[0048] Existing equipment requires frequent changes to the detection points and repositioning of the signal lines. Furthermore, due to the overhead lines, the signal lines need to be quite long. Since typical signal lines are pre-wound, they easily become loose, messy, or tangled during use, causing significant inconvenience and wasting time and effort. This new device, however, features a sliding frame 501 at the front of the online detection equipment 1. During operation, the cable 511 is connected to one end of the hook link. Pulling the hook link rotates the winding shaft 504, facilitating cable unwinding. For winding, rotating the rotating rod 506 drives the hollow cylinder 507 and the rotating arm. Rotating 505 causes the winding shaft 504 to rotate, facilitating the winding of the cable 511. This design not only ensures that the cable 511 is not easily loosened or tangled, but also facilitates winding when changing the testing location, greatly saving time and ensuring testing efficiency. To ensure the winding efficiency of the cable 511, the rotating rod 506 is slid outward, causing one end of the rotating rod 506 to move into the hollow cylinder 507. The purpose of winding the cable 511 can be achieved directly by rotating the rotating rod 506. When not in use, one side of the rotating rod 506 is located inside the limiting hole 503, and the first magnetic ring 508 and the second magnetic ring 509 cooperate to prevent the rotating rod 506 from separating from the limiting hole 503 on its own, which would prevent the sliding frame 501 from sliding smoothly into the online testing device 1.

[0049] In this embodiment, the storage rack 510 is arranged in three groups, which are triangularly arranged inside the sliding frame 501. There is one storage rack 510 on the front side and two storage racks 510 arranged horizontally side by side on the rear side. Two sets of side grooves 502 are opened on one side of the sliding frame 501 and one set of side grooves are opened on the other side. This makes it convenient for the rotating rod 506 to drive the hollow cylinder 507 and the rotating arm 505 to rotate, so as to achieve the purpose of winding the line.

[0050] The first magnetic ring 508 and the second magnetic ring 509 use the principle of same polarity repulsion and different polarity attraction to fix the rotating rod 506, so as to ensure the normal sliding of the sliding frame 501.

[0051] Embodiment 2: This embodiment is an improvement on Embodiment 1, please refer to Figure 5 Specifically, the rear side plate of the sliding frame 501 is slidingly connected with three groups of transverse rods 7, one end of the transverse rod 7 is fixedly connected with the online detection equipment 1, and the other end of the transverse rod 7 is fixedly connected with a limiting frame 8.

[0052] The side of the limiting frame 8 away from the transverse rod 7 is arc-shaped, and the arc surface of the limiting frame 8 is fixedly connected with a plurality of uniformly distributed teeth.

[0053] The limiting frame 8 can cooperate with the anti-loosening mechanism 6 to achieve the purpose of fixing the anti-loosening mechanism 6.

[0054] In this embodiment, the transverse rod 7 penetrates through the rear side plate of the sliding frame 501, and when the sliding frame 501 is reset, the limiting frame 8 on one side of the transverse rod 7 cooperates with the anti-loosening mechanism 6 through the internal teeth, so as to achieve the purpose of fixing the anti-loosening mechanism 6, and further fix the cable 511 of the cable winding assembly 5.
