Description

Technical Field

[0001] The invention relates to the technical field of line fault detection, in particular to an on-line detection device for ground fault distance measurement. Background Art

[0002] In life, we often encounter short circuits in lines. When detecting faults in overhead lines, we often need to use professional testers. After a ground fault occurs in the line, we need to test it. First, make sure that the line is out of power, then connect one end of the three sets of red signal lines to the hook link stick, and the other end of the signal line to one end of the positioning device host. The host is grounded, turn on the signal collector and signal receiver, make sure they are in normal use, connect the signal collector to the telescopic rod, and hang the three hook link sticks on the three guides of the faulty line respectively. Start the host and inject the signal into the faulty line. , three-phase currents are detected on both sides of the injection point, and the fault point is determined according to the three-phase currents. However, this setting requires frequent changes in the detection point when in use, and the signal line needs to be moved back and forth. At the same time, since it is an overhead line, the signal line needs to be longer, and the general signal line is wound. When in use, the signal line needs to be unfolded, and the signal line is very easy to become loose and messy or entangled in one place, which is very inconvenient to use. It is also very inconvenient to reel it up, which greatly wastes time and costs, and also delays work efficiency. Therefore, in view of the above problems, an online detection device for ground fault ranging is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide an on-line detection device for ground fault distance measurement to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] As an optional solution of the on-line detection device for measuring the distance between ground faults described in the present invention, wherein: an on-line detection device for measuring the distance between ground faults comprises an on-line detection device, an inner buckle cover and a pad;

[0006] A plurality of groups of pads for supporting the online detection equipment are installed at the bottom of the online detection equipment;

[0007] An operation panel is installed on the top of the online detection device;

[0008] An inner buckle cover for shielding the operation panel is also installed on the side of the online detection device;

[0009] A cable winding assembly for placing cables is installed on the front side of the online detection device, and three sets of anti-loosening mechanisms are installed inside the cable winding assembly;

[0010] The cable winding assembly comprises a sliding frame, a side groove and a limiting hole. The side of the sliding frame is provided with a side groove, and a plurality of limiting holes are arranged inside the side groove. A winding shaft is rotatably connected to the central position of the side groove, a rotating arm is fixedly connected to one side of the winding shaft, and a hollow cylinder is fixedly connected to the other end of the rotating arm.

[0011] The outer side of the winding shaft is rotatably connected to a storage rack, the interior of the storage rack is provided with a cable wound around the outer side of the winding shaft, the outer side of the storage rack is also rotatably connected to a support rack, and the bottom of the support rack is fixedly connected to the sliding frame;

[0012] One side of the support frame is fixedly connected with an anti-loosening mechanism.

[0013] As an optional solution of the ground fault distance online detection device described in the present invention, wherein: a rotating rod is slidably connected to the interior of the hollow cylinder, and the rotating rod is arranged in an I-shaped configuration.

[0014] As an optional solution of the ground fault ranging online detection device described in the present invention, a first magnetic ring is installed on one side of the interior of the hollow cylinder, and a second magnetic ring fixedly connected to the rotating rod is provided on one side of the first magnetic ring, and the opposite end faces of the first magnetic ring and the second magnetic ring are arranged with different poles.

[0015] When the existing equipment is in use, it is necessary to frequently change the detection point and move the signal line back and forth. At the same time, because it is an overhead line, the signal line needs to be long, and the general signal line is wound. When in use, the signal line needs to be unfolded, and the signal line is very easy to become loose and messy or tangled in one place, which is very inconvenient to use. It is also very inconvenient to reel it up, which greatly wastes time and cost, and also delays work efficiency. When the present device is in use, a sliding frame is provided on the front side of the online detection device. When in use, the cable is connected to one end of the hook link rod. The hook link rod can be directly pulled to drive the reel to rotate, thereby facilitating the cable unwinding work. When rewinding, By rotating the rotating rod, the hollow cylinder and the rotating arm can be driven to rotate, thereby rotating the winding shaft, which is convenient for storing the cable. This arrangement not only ensures that the cable is not easily loosely entangled, but also makes it convenient to reel in when changing the detection location, greatly saving time cost and ensuring the efficiency of detection. In order to ensure the reeling 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 purpose of reeling in the cable can be achieved directly by 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 prevent the rotating rod from separating from the limiting hole without permission, which causes the sliding frame to be unable to slide smoothly into the online detection equipment.

[0016] As an optional solution of the ground fault ranging online detection device described in the present invention, the rear side plate of the sliding frame is slidably connected with three groups of transverse rods, and one end of the transverse rod is fixedly connected to the online detection equipment, and the other end of the transverse rod is fixedly connected to the limiting frame.

[0017] As an optional solution of the ground fault distance online detection device described in the present invention, the side of the limit frame facing away from the transverse rod is arranged in an arc surface, and the arc surface of the limit frame is fixedly connected with a plurality of evenly distributed teeth.

[0018] The provided limiting frame can cooperate with the anti-loosening mechanism to achieve the purpose of fixing the anti-loosening mechanism.

[0019] The anti-loosening mechanism includes a base plate, a guide cylinder and a sliding rod. The bottom of the base plate is fixedly connected to the online detection equipment, the top of the base plate is fixedly connected to the guide cylinder, and the inside of the guide cylinder is slidably connected to the sliding plate, one side of the sliding plate is fixedly connected to the sliding rod, the other end of the sliding rod is rotatably connected to a rotating column, the outer side of the rotating column is fixedly connected to a rotating sleeve, and one side of the rotating column is also fixedly connected to a gear.

[0020] As an optional solution of the ground fault distance online detection device described in the present invention, the outer diameter of the gear is 0.8 times the outer diameter of the rotating sleeve.

[0021] As an optional solution of the ground fault distance online detection device described in the present invention, a spring is fixedly connected to the bottom of the sliding plate, and the other end of the spring is fixedly connected to the guide cylinder.

[0022] As an optional solution of the ground fault distance online detection device described in the present invention, the guide cylinder and the sliding rod are both arranged in an inclined manner.

[0023] When the cable is in use, the spring provided therein squeezes 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, which can effectively prevent the cable from loosening and ensure that the cable is tightly wound. When the sliding frame slides into the interior of the online detection equipment, the limit frame on one side of the transverse rod cooperates with the gear on one side of the rotating column, which can prevent the rotating sleeve from rotating, thereby effectively supporting the cable and preventing it from loosening.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the present invention is in use, a 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 hook link rod. The hook link rod can be directly pulled to drive the winding shaft to rotate, so as to facilitate the cable to release the cable. When winding the cable, the hollow cylinder and the rotating arm can be driven to rotate by rotating the rotating rod, so that the winding shaft can be rotated, which is convenient for storing the cable. This arrangement not only ensures that the cable is not easily loosely wound, but also facilitates winding when changing the detection location, greatly saves time cost, and ensures the efficiency of detection.

[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. 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 prevent the rotating rod from being separated from the limiting hole privately, causing the sliding frame to be unable to slide smoothly into the online detection device.

[0027] When the cable is in use, the spring provided therein squeezes 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, which can effectively prevent the cable from loosening privately and ensure that the cable is tightly wound;

[0028] When the sliding frame slides into the online detection device, the limit frame on one side of the transverse rod cooperates with the gear on one side of the rotating column, which can prevent the rotating sleeve from rotating, effectively supporting the cable and preventing it from loosening.

[0037] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present invention provides a technical solution:

[0038] An on-line detection device for ground fault distance measurement, comprising an on-line detection device 1, an inner buckle cover 2 and a cushion block 3;

[0039] A plurality of pads 3 for supporting the online detection device 1 are installed at the bottom of the online detection device 1;

[0040] An operation panel 4 is installed on the top of the online detection device 1;

[0041] The side of the online detection device 1 is also equipped with an inner buckle cover 2 for shielding the operation panel 4;

[0042] A cable winding assembly 5 for placing cables is installed at the front side of the online detection device 1, and three sets of anti-loosening mechanisms 6 are installed inside the cable winding assembly 5;

[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 a plurality of limiting holes 503 are arranged inside the side groove 502. A winding shaft 504 is rotatably connected to the central position of the side groove 502, a rotating arm 505 is fixedly connected to one side of the winding shaft 504, and a hollow cylinder 507 is fixedly connected to the other end of the rotating arm 505.

[0044] The outer side of the reel 504 is rotatably connected to a storage rack 510, and the interior of the storage rack 510 is provided with a cable 511 wound around the outer side of the reel 504. The outer side of the storage rack 510 is also rotatably connected to a support rack 512, and the bottom of the support rack 512 is fixedly connected to the sliding frame 501;

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

[0046] The hollow cylinder 507 is slidably connected with a rotating rod 506 inside, and the rotating rod 506 is arranged in an I-shaped configuration.

[0047] A first magnetic ring 508 is installed on one side of the inner part of the hollow cylinder 507, and a second magnetic ring 509 fixedly connected to the rotating rod 506 is provided 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] When the existing equipment is in use, it is necessary to frequently change the detection point and move the signal line back and forth. At the same time, since it is an overhead line, the signal line needs to be relatively long, and the general signal line is wound. When in use, the signal line needs to be unfolded, and the signal line is very easy to become loose and messy or tangled in one place, which is very inconvenient to use. It is also very inconvenient to reel it up, which greatly wastes time and also delays work efficiency. When the present device is in use, a sliding frame 501 is provided on the front side of the online detection device 1. When in use, the cable 511 is connected to one end of the hook rod. The hook rod can be directly pulled to drive the reel 504 to rotate, thereby facilitating the cable 511 to release the line. When reeling in the line, the hollow cylinder 507 and the rotating arm can be driven by rotating the rotating rod 506. 505 rotates, thereby rotating the winding shaft 504, which is convenient for storing the cable 511. This arrangement not only ensures that the cable 511 is not easily loosely wound, but also facilitates winding when changing the detection location, greatly saving time and cost, and ensuring the efficiency of detection. In order to ensure the winding efficiency of the cable 511, the rotating rod 506 is slid outward so that one end of the rotating rod 506 is displaced inside 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 being separated from the limiting hole 503 privately, resulting in the sliding frame 501 being unable to slide smoothly into the online detection device 1.

[0049] In this embodiment, the storage rack 510 is arranged in three groups, which are arranged in a triangular shape inside the sliding frame 501, with one storage rack 510 on the front side and two storage racks 510 arranged side by side in a horizontal direction on the rear side. Two groups of side grooves 502 are opened on one side of the sliding frame 501, and one group of side grooves is opened on the other side, so that the rotating rod 506 can drive the hollow cylinder 507 and the rotating arm 505 to rotate, so as to achieve the purpose of winding the wire;

[0050] The first magnetic ring 508 and the second magnetic ring 509 utilize the principle that like charges repel and opposite charges attract to fix the rotating rod 506 and ensure that the sliding frame 501 slides normally.

[0051] Example 2: This example is an improvement on Example 1. Figure 5 Specifically, the rear side plate of the sliding frame 501 is slidably connected with three groups of transverse rods 7, and one end of the transverse rod 7 is fixedly connected to the online detection device 1, and the other end of the transverse rod 7 is fixedly connected to the limiting frame 8.

[0052] The side of the limiting frame 8 facing away from the transverse rod 7 is arranged in an arc surface, and the arc surface of the limiting frame 8 is fixedly connected with a plurality of evenly distributed teeth.

[0053] The provided 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 passes through the rear side plate of the sliding frame 501. When the sliding frame 501 is reset, the limit frame 8 on one side of the transverse rod 7 cooperates with the anti-loosening mechanism 6 through the internal teeth to achieve the purpose of fixing the anti-loosening mechanism 6, thereby achieving a certain fixing purpose of the cable 511 of the cable winding assembly 5.

[0055] Example 3: This example is an improvement on Example 2. Figure 6 and Figure 7 Specifically, the anti-loosening mechanism 6 includes a base plate 601, a guide cylinder 602 and a sliding rod 603. The bottom of the base plate 601 is fixedly connected to the online detection device 1. The guide cylinder 602 is fixedly connected to the top of the base plate 601, and the inside of the guide cylinder 602 is slidably connected to a sliding plate 606. One side of the sliding plate 606 is fixedly connected to the sliding rod 603. The other end of the sliding rod 603 is rotatably connected to a rotating column 604. The outer side of the rotating column 604 is fixedly connected to a rotating sleeve 605. One side of the rotating column 604 is also fixedly connected to a gear 608.

[0056] The outer diameter of the gear 608 is 0.8 times the outer diameter of the rotating sleeve 605 .

[0057] A spring 607 is fixedly connected to the bottom of the sliding plate 606 , and the other end of the spring 607 is fixedly connected to the guide cylinder 602 .

[0058] The guide cylinder 602 and the sliding rod 603 are both arranged to be inclined.

[0059] When the cable 511 is in use, the spring 607 provided therein squeezes the sliding plate 606, so that the sliding rod 603 drives the rotating column 604 and the rotating sleeve 605 to move, and the rotating sleeve 605 is in close contact with the cable 511, which can effectively prevent the cable 511 from loosening privately and ensure that the cable 511 is tightly wound;

[0060] When the sliding frame 501 slides into the inside of the online detection device 1, the limit frame 8 on one side of the transverse rod 7 cooperates with the gear 608 on one side of the rotating column 604, which can prevent the rotating sleeve 605 from rotating, effectively supporting the cable 511 and preventing it from loosening;

[0061] In this embodiment, the outer diameter of the gear 608 is smaller than the rotating sleeve 605, so as to prevent the gear 608 from contacting the cable 511 and causing it to loosen. At the same time, the setting of the spring 507 can ensure the support of the sliding plate 606, so that the sliding rod 603 drives the rotating column 604 and the rotating sleeve 605 on one side to move, and the rotating sleeve 605 contacts the cable 511, so as to achieve the purpose of support.

[0062] The guide cylinder 602 and the sliding rod 603 are both arranged to be inclined, so as to ensure that the rotating sleeve 605 is in contact with the cable 511 .
