Description

Technical Field

[0001] This utility model relates to the field of cable short-circuiting technology, specifically providing a cable short-circuiting device at any point. Background Technology

[0002] Currently, power maintenance personnel need to cut one of the multiple underground cables, so they need to shut off the power to that cable first. However, since most of the underground cables are of the same type and have very similar appearances, it is not possible to quickly locate which cable has been shut off.

[0003] The current approach involves using a principle similar to a nail gun to quickly locate unenergized target cables. On-site personnel remotely operate a nail gun, causing the nail to quickly penetrate the cable sheath and embed itself into the battery cells. Because the nail is long enough and metallic, when it penetrates any or multiple battery cells: if the cable is energized, a micro-explosion will occur immediately; if the cable is not energized, there will be no reaction. The operator can then identify the unresponsive cable as the target cable.

[0004] However, this method has the potential for short-circuit deviation. The nail may pass between the electrical cores inside the cable instead of actually penetrating them to create a short circuit. This prevents a micro-explosion, which could mislead workers into believing the cable is not live and causing them to cut it directly, resulting in electric shock and endangering their lives. Utility Model Content

[0005] This invention provides a cable short-circuiting device at any point, which solves the problem that in the prior art, when using a nail gun to short-circuit cables, personnel are prone to misjudgment if a short-circuit deviation occurs.

[0006] This utility model provides a cable arbitrary point short-circuiting device, comprising:

[0007] Clamping mechanism, used to clamp cables;

[0008] A sliding frame is slidably disposed on the clamping mechanism;

[0009] A locking mechanism is provided on the sliding frame and acts on the clamping mechanism to constrain the sliding between the sliding frame and the clamping mechanism;

[0010] A telescopic mechanism, wherein the telescopic direction of the telescopic mechanism is perpendicular to the clamping direction of the clamping mechanism, and one end is fixedly connected to the sliding frame;

[0011] A rotary drive component is installed at the other end of the telescopic mechanism;

[0012] A spiral drill bit is coaxially mounted on the output end of the rotary drive component;

[0013] The control module is electrically connected to both the telescopic mechanism and the rotary drive component.

[0014] According to the cable arbitrary point short-circuiting device provided by this utility model, the clamping mechanism includes:

[0015] Screw;

[0016] The clamping claw has at least two claws, wherein the first clamping claw is fixed to one end of the screw, and the second clamping claw is slidably mounted on the screw along the axial direction of the screw;

[0017] A lock nut, threaded onto the screw;

[0018] The second clamping claw is located between the first clamping claw and the locking nut.

[0019] According to the cable arbitrary point short-circuiting device provided by this utility model, the sliding frame includes:

[0020] A slider is slidably mounted on the clamping mechanism along the clamping direction;

[0021] The cantilever is fixedly installed on the slider.

[0022] According to the cable arbitrary point short-circuiting device provided by this utility model, the locking mechanism includes: a set screw, which is threadedly installed on the slider and passes through the slider to abut against the clamping mechanism.

[0023] According to the cable arbitrary point short-circuiting device provided by this utility model, the telescopic mechanism includes an electric telescopic rod.

[0024] According to the cable arbitrary point short-circuiting device provided by this utility model, the screw is provided with at least two symmetrical sliding grooves along the axial direction;

[0025] The slider is sleeved on the screw, and a limit key is formed on the inner wall of the slider. The limit key is installed in conjunction with the groove.

[0026] According to the cable arbitrary point short-circuiting device provided by this utility model, the opposing surfaces of the clamping claws are each formed with multiple protrusions.

[0027] According to the cable arbitrary point short-circuiting device provided by this utility model, the control module includes:

[0028] The controller is electrically connected to the telescopic mechanism and the rotary drive component;

[0029] A torque sensor is electrically connected to the rotary drive component;

[0030] The processor is electrically connected to both the controller and the torque sensor.

[0031] This utility model provides a cable short-circuiting device at any point. By setting a sliding frame on the clamping mechanism, a telescopic mechanism on the sliding frame, and a rotary drive and a auger drill bit on the telescopic mechanism, the auger drill bit can reciprocate in the telescopic direction while rotating, thus drilling through the cable and allowing the metal drill bit to enter the battery cell, thereby achieving a short circuit. The auger drill bit allows for real-time observation of drilling debris. If metal debris is detected, it can be directly determined that the battery cell has been successfully short-circuited. If no micro-explosion occurs, the cable can be directly identified as the target cable, and further work can proceed. This effectively solves the problem of misjudgment when using a nail gun for short-circuiting in existing technologies, where short-circuiting deviations can lead to errors. Specifically:

[0032] The clamping mechanism is used to clamp the cable and fix the shorting device to the cable surface. The sliding frame drives the telescopic mechanism to reciprocate on the clamping mechanism. The locking mechanism restricts the movement of the sliding frame on the clamping mechanism and fixes the sliding frame at a suitable position to prevent the vibration of the drill rod from causing the sliding frame to move during operation. The telescopic mechanism, with its extension direction perpendicular to the clamping direction, ensures that the telescopic mechanism reciprocates up and down along the radial direction of the cable. The telescopic mechanism drives the auger drill bit to reciprocate up and down to drill through the cable.

[0033] The rotary drive unit enables the auger bit to rotate; the auger bit also allows it to simultaneously remove battery cell slag and insulation layer slag generated during drilling, facilitating direct detection of short circuits; the control module controls the vertical movement of the telescopic mechanism and the rotation of the rotary drive unit.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0053] The following is combined Figures 1 to 10 The embodiments shown illustrate the technical solution of this utility model:

[0054] This utility model embodiment provides a cable arbitrary point short-circuiting device, such as... Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, it includes: clamping mechanism 1, sliding frame 2, locking mechanism 3, telescopic mechanism 4, rotary drive component 5, auger drill bit 6, and control module 7;

[0055] The system includes: a clamping mechanism 1 for clamping cables; a sliding frame 2 slidably mounted on the clamping mechanism 1; a locking mechanism 3 mounted on the sliding frame 2 and acting on the clamping mechanism 1 to constrain the sliding between the sliding frame 2 and the clamping mechanism 1; a telescopic mechanism 4 whose telescopic direction is perpendicular to the clamping direction of the clamping mechanism 1, and one end is fixedly connected to the sliding frame 2; a rotary drive 5 mounted on the other end of the telescopic mechanism 4; a spiral drill bit 6 coaxially mounted on the output end of the rotary drive 5; and a control module 7 electrically connected to both the telescopic mechanism 4 and the rotary drive 5.

[0056] Understandably, the locking mechanism 3 can be designed to work with a pin or bolt, which is sufficient to constrain the sliding frame 2 and the clamping mechanism 1 to slide; the telescopic mechanism 4 can be designed as a hydraulic cylinder or a sleeve mechanism, which is sufficient to enable up and down movement.

[0057] In this embodiment, as Figure 1 As shown, the clamping mechanism 1 clamps the cable 8, and the sliding frame 2 can drive the telescopic mechanism 4 to move laterally to any position. When it reaches the appropriate position, the rotating locking mechanism 3 fixes the sliding frame 2 to the clamping mechanism 1. The control module 7 is electrically connected to the telescopic mechanism 4 and the rotating drive 5, and controls the telescopic mechanism 4 to move down, so that the auger drill bit 6 moves down to contact the cable 8. The rotating drive 5 drives the auger drill bit 6 to rotate. The two work together to complete the downward drilling process, so that the battery cell 801 is short-circuited, and the cable 8 is de-energized.

[0058] This utility model provides a cable arbitrary point short-circuiting device. By setting a sliding frame 2 on a clamping mechanism 1, a telescopic mechanism 4 on the sliding frame 2, and a rotary drive 5 and a spiral drill bit 6 on the telescopic mechanism 4, the spiral drill bit 6 can reciprocate in the telescopic direction of the telescopic mechanism 4 while rotating. This allows drilling through the cable 8, enabling the metal drill bit to enter the battery cell 801, thus achieving a short circuit in the battery cell 801. The spiral drill bit 6 allows for real-time observation of drilling debris. If metal debris is detected, it can be directly determined that the battery cell 801 has been successfully short-circuited. If no micro-explosion occurs, the cable can be directly identified as the target cable, and work can proceed directly. This effectively solves the problem of misjudgment when using a nail gun for short-circuiting in the prior art, especially when there is a short-circuit deviation. Specifically:

[0059] The clamping mechanism 1 is used to clamp the cable 8, and at the same time, the shorting device can be fixedly connected to the surface of the cable 8. The sliding frame 2 drives the telescopic mechanism 4 to reciprocate on the clamping mechanism 1. The locking mechanism 3 can constrain the movement of the sliding frame 2 on the clamping mechanism 1 and fix the sliding frame 2 at a suitable position to prevent the vibration of the drill rod from causing the sliding frame 2 to move during operation. The telescopic mechanism 4 is set up, and the telescopic direction of the telescopic mechanism 4 is perpendicular to the clamping direction of the clamping mechanism 1, ensuring that the telescopic mechanism 4 reciprocates up and down along the radial direction of the cable 8. The telescopic mechanism 4 drives the auger drill bit 6 to reciprocate up and down to drill through the cable 8.

[0060] The rotary drive component 5 can drive the auger drill bit 6 to rotate. When the auger drill bit 6 is working, it can simultaneously bring out the battery cell 801 slag and insulation layer slag generated during the drilling process, which is conducive to directly judging whether there is a short circuit. The control module 7 controls the up and down movement of the telescopic mechanism 4 and the rotation of the rotary drive component 5.

[0061] It should be noted that inducing a micro-explosion in the cable through short-circuiting results in negligible damage. Compared to endangering human life, this is of greater significance.

[0062] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 3 and Figure 10 As shown, the clamping mechanism 1 includes:

[0063] Screw 101;

[0064] The clamping claws 102 are at least two, wherein the first clamping claw 1021 is fixed to one end of the screw 101, and the second clamping claw 1022 is slidably mounted on the screw 101 along the axial direction of the screw 101;

[0065] Locking nut 103 is threaded onto screw 101;

[0066] The second clamping claw 1022 is located between the first clamping claw 1021 and the locking nut 103.

[0067] In this embodiment, there are at least two clamping claws 102. The first clamping claw 1021 is a fixed clamping claw installed at one end of the screw 101, and the second clamping claw 1022 is a sliding clamping claw, which is axially slidably installed at the other end of the screw 101. When working, the second clamping claw 1022 is initially moved away from the first clamping claw 1021 to ensure that the distance between the clamping claws 102 is greater than the diameter of the cable 8. The screw 101 is then placed across the cable 8, and the first clamping claw 1021 abuts against one end of the cable 8. The second clamping claw 1022 is then moved to abut against the other end of the cable 8, thereby clamping the cable 8 through the first clamping claw 1021 and the second clamping claw 1022. By rotating the locking nut 103, the clamping claws 102 clamp the cable 8.

[0068] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 4 and Figure 10 As shown, the sliding frame 2 includes:

[0069] Slider 201 is slidably mounted on clamping mechanism 1 along the clamping direction;

[0070] The cantilever 202 is fixedly installed on the slider 201.

[0071] In this embodiment, there are two sliders 201, which are slidably mounted on the screw 101 of the clamping mechanism 1. A cantilever 202 is mounted on the slider 201. When the slider 201 moves, it drives the cantilever 202 to move. A telescopic mechanism 4 is mounted on the cantilever 202, which in turn drives the telescopic mechanism 4 to move, so that the auger drill bit 6 can move at any position in the clamping section of the cable 8, thereby performing drilling.

[0072] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 10 As shown, the locking mechanism 3 includes: a set screw 301, which is threaded onto the slider 201 and passes through the slider 201 to abut against the clamping mechanism 1.

[0073] In this embodiment, the locking mechanism 3 is preferably a set screw 301, which is threaded onto the slider 201 and passes through the slider 201 to abut against the screw 101 of the clamping mechanism 1. When the slider 201 moves to a suitable position, the set screw 301 is rotated to rotate and abut against the screw 101, thereby fixing the sliding frame 2 onto the screw 101 of the clamping mechanism 1. This prevents the sliding frame 2 from moving due to vibration during operation, which could damage the drill bit or increase drilling time, and ultimately cause problems such as unsuccessful short-circuiting of the cable 8.

[0074] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 6 As shown, the telescopic mechanism 4 includes an electric telescopic rod 401.

[0075] In this embodiment, the telescopic mechanism 4 is preferably an electric telescopic rod 401, which provides more accurate and automated control. The built-in sensor automatically stops when it encounters an obstacle and automatically locks after telescopic extension.

[0076] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 7 and Figure 10 As shown, the screw 101 has at least two symmetrical grooves 1011 along the axial direction;

[0077] The slider 201 is sleeved on the screw 101, and a limit key 2011 is formed on the inner wall of the slider 201. The limit key 2011 is installed in conjunction with the slide groove 1011.

[0078] In this embodiment, two symmetrical sliding grooves 1011 are axially provided on the screw 101, and a limit key 2011 is formed on the inner wall of the slider 201 sleeved on the screw 101. The limit key 2011 allows the slider 201 to move along the sliding groove 1011, thereby driving the sliding frame 2 to move axially on the screw 101, driving the telescopic mechanism 4 to move axially, so that the auger drill bit 6 can act on any position of the locking section of the cable 8.

[0079] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 8 and Figure 10 As shown, multiple protrusions 1023 are formed on the opposite surfaces of the gripper 102.

[0080] In this embodiment, the clamping claw 102 has multiple protrusions 1023 on opposite surfaces to further lock the cable 8 and prevent the cable 8 from being too smooth. Vibration during drilling could cause the short-circuiting device to slip, resulting in the failure to short-circuit the battery cell 801.

[0081] According to the short-circuiting device provided in the embodiments of this utility model, such as Figure 1 , Figure 9 and Figure 10 As shown, control module 7 includes:

[0082] The controller 701 is electrically connected to the telescopic mechanism 4 and the rotary drive 5;

[0083] Torque sensor 702 is electrically connected to rotary drive component 5;

[0084] The processor 703 is electrically connected to the controller 701 and the torque sensor 702, respectively.

[0085] In this embodiment, the processor 703 controls the operation of the controller 701 and the torque sensor 702. The torque sensor 702 is electrically connected to the rotary drive 5. The processor 703 controls the operation of the controller 701, causing the telescopic mechanism 4, which is electrically connected to the controller 701, to drive the auger drill bit 6 to move downward. At the same time, the rotary drive 5, which is electrically connected to the controller 701, drives the auger drill bit 6 to rotate, contacting the insulation layer on the surface of the cable 8 and starting to drill through. After a period of time, when the torque of the torque sensor 702 suddenly matches the initial torque during the drilling process, the battery cell 801 at that position has been drilled through. The battery cell 801 is short-circuited, the cable 8 is successfully de-energized, the controller 701 controls the rotary drive 5 to stop rotating, and controls the telescopic mechanism 4 to drive the auger drill bit 6 to move upward away from the cable 8.

[0086] like Figure 10 As shown, when this shorting device is working, it clamps the cable 8, which contains 4 battery cores 801. When working, the shorting device drills through the cable 8 and contacts the battery cores 801, so that the battery cores 801 are shorted and the cable 8 is successfully de-energized.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
