Description

Technical Field

[0001] This invention relates to a safety tool for piercing high-voltage cables to determine if they are energized, and more particularly to a high-voltage cable piercing device and piercing method, belonging to the field of cable testing technology. Background Technology

[0002] Cables are typically rope-like structures made up of several or groups of conductors (at least two conductors per group), with each group of conductors insulated from each other and often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated.

[0003] For many years, cable operation and maintenance departments have conducted piercing tests on high-voltage cables before cutting them to ensure that the cables under maintenance are not energized. This has been done in accordance with Article 234 of the industry standard DL409-91 "Electrical Safety Work Regulations (Power Line Section)," using manual piercing. The manual piercing method involves hammering steel nails into the cable with a hammer. Although cable identification devices are used to check for energization before piercing, and the identification rate is high, a misidentification and accidental piercing of a live cable can cause significant harm to the operator, even posing a life-threatening risk. While wirelessly controlled gunpowder-launched piercing devices have appeared on the market, these devices pose certain safety hazards in gunpowder storage and filling processes. Furthermore, they are inefficient, and the gunpowder is susceptible to moisture in humid environments, affecting its usability. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a high-voltage cable piercing device and piercing method that is reasonably designed, safe to use, and highly efficient.

[0005] The technical solution adopted by this invention to solve the above problems is as follows: The high-voltage cable piercing device is characterized by the following structure: it includes a circuit board, a housing, a lighting lamp, a camera, a main unit, a battery, and a remote control. The main unit includes a first power motor, a drill bit clamping component, a drill bit, a cable clamping component, a feed mechanism, a second power motor, and a limiting block. The drill bit clamping component and the drill bit are both made of metal. The feed mechanism is connected to the second power motor. The drill bit clamping component is mounted on the feed mechanism. The limiting block is fixed on the feed mechanism and cooperates with the drill bit clamping component. The first power motor is connected to the drill bit clamping component. The drill bit is mounted on the drill bit clamping component. The cable clamping component is fixed to the front end of the feed mechanism at the head clamping part, and the cable clamping component cooperates with the drill bit; the housing is provided with a battery socket and a main unit mounting cavity, the main unit is installed in the main unit mounting cavity, and the drill bit and cable clamping component are exposed outside the housing; the lighting lamp and camera are both installed on the housing, and the lighting lamp and camera are close to the drill bit; the circuit board is installed inside the housing, and the lighting lamp, camera and main unit are all connected to the circuit board; the battery is installed in the battery socket of the housing, and the circuit board, lighting lamp, camera and main unit are all connected to the battery; the remote control and the circuit board are wirelessly connected.

[0006] Preferably, the drill bit clamping component of the present invention includes a mounting base, an output shaft, and a mounting cover. The mounting base is mounted on the feed mechanism, the output shaft is rotatably mounted on the mounting base, and the two ends of the output shaft are respectively connected to a power motor and the drill bit. The mounting cover is installed at the connection between the output shaft and the drill bit.

[0008] Preferably, the cable clamping component of the present invention further includes a dustproof ring, which is fixed on the first hole of the connecting plate and cooperates with the output shaft of the drill bit clamping component.

[0009] A high-voltage cable piercing method is characterized by the following steps: Manually place the cable into the cable clamping component, secure the cable with a lock nut, insert the battery, press the power switch (the light will illuminate), turn on the camera display, and the camera will begin operation; turn on the remote control, select manual mode, press the drill bit operation button on the remote control, and the first power motor will operate, driving the drill bit through the drill bit clamping component; press and hold the forward button on the remote control, and the second power motor will operate, causing the feed mechanism to move the drill bit clamping component forward, thus moving the entire drill bit... Before starting the operation, the drill bit begins to pierce the cable. At this time, the piercing process is observed through the camera's display screen. When copper shavings are observed flying out, it indicates that the drill bit has made contact with the copper conductor inside the cable. At this point, release the forward button on the remote control, the second motor stops working, and the feed mechanism stops moving forward. Press and hold the reverse button on the remote control, the second motor drives the feed mechanism to move backward, and the drill bit begins to withdraw from the cable. When the drill bit has completely withdrawn, release the reverse button on the remote control and press the stop button on the remote control, and the drill bit stops working.

When copper shavings are seen flying out, it indicates that the drill has made contact with the copper conductor inside the cable. At this point, press the stop button on the remote control to stop the operation, or do not operate and wait for the piercing device to continue moving forward. When the feed mechanism reaches the set position of the limit block, the piercing device will automatically stop moving forward. At this point, press the reverse button on the remote control, and the drill bit clamping part will move backward. When it returns to the initial position, the operation will stop.

[0023] Example

[0025] The host unit 5 in this embodiment includes a first power motor 51, a drill bit clamping component 52, a drill bit 53, a cable clamping component 54, a feed mechanism 56, a second power motor 57, and a limiting block 58.

The first power motor 51 drives the drill bit 53 to rotate. The cable clamping component 54 is fixed to the front end of the feed mechanism 56 and cooperates with the drill bit 53.

[0026] In this embodiment, the outer casing 2 is provided with a battery socket 6 and a main unit mounting cavity 9. The main unit 5 is installed in the main unit mounting cavity 9, while the drill bit 53 and the cable clamping component 54 are exposed outside the outer casing 2.

The circuit board 1 is installed inside the outer casing 2, and the lighting lamp 3, the camera 4, and the main unit 5 are all connected to the circuit board 1. The circuit board 1 is a control program carrier that controls the overall movement and operation of the piercing device, which is common knowledge to those skilled in the art. The battery 7 is installed in the battery socket 6 of the outer casing 2, and the circuit board 1, the lighting lamp 3, the camera 4, and the main unit 5 are all connected to the battery 7. The remote control 8 is wirelessly connected to the circuit board 1 and is used for remote command input.

[0027] The drill bit clamping component 52 in this embodiment includes a mounting base 61, an output shaft 62, and a mounting cover 63. The mounting base 61 is mounted on the feed mechanism 56, and the output shaft 62 is rotatably mounted on the mounting base 61. The two ends of the output shaft 62 are respectively connected to the power motor 51 and the drill bit 53. The mounting cover 63 is installed at the connection between the output shaft 62 and the drill bit 53.

[0028] The cable clamping component 54 in this embodiment includes a locking nut 71, a connecting plate 72, a connecting bolt 73, a support plate 74, a pressure plate 75, and a dustproof ring 76. The connecting plate 72 is fixed to the front end of the feed mechanism 56, and has a first hole 77 for the output shaft 62 and the drill bit 53 to pass through. The support plate 74 is fixed to the connecting plate 72, and has a second hole 78 for the drill bit 53 to pass through. The pressure plate 75 is connected to the connecting plate 72 by the locking nut 71 and the connecting bolt 73. Both the support plate 74 and the pressure plate 75 have an arc-shaped structure, forming an area for clamping the cable 55 between them. The dustproof ring 76 is fixed to the first hole 77 of the connecting plate 72, and the dustproof ring 76 cooperates with the output shaft 62 of the drill bit clamping component 52.

[0029] The high-voltage cable piercing method in this embodiment is divided into manual mode and automatic mode. The steps of manual mode are as follows: Manually place the cable 55 into the cable clamping component 54, fix the cable 55 with the locking nut 71, insert the battery 7, press the power switch, at which time the lighting lamp 3 is lit, turn on the display switch of the camera 4, at which time the camera 4 is working; turn on the switch of the remote control 8, select manual mode, press the drill bit working button on the remote control 8, the power motor 1 51 works and drives the drill bit 53 to work through the drill bit clamping component 52, press and hold the forward button on the remote control 8, the power motor 2 57 works, under the action of the power motor 2 57, the feed mechanism 56 drives the drill bit clamping component 52 to move forward, so that the drill bit 53 can move forward. The drill bit 53 moves forward as a whole, and begins to pierce the cable 55. At this time, the piercing situation of the cable 55 is observed through the display screen of the camera 4. When copper shavings are observed flying out, it indicates that it has made contact with the copper wire inside the cable 55. At this time, the forward button on the remote control 8 is released, the second motor 57 stops working, and the feed mechanism 56 stops moving forward. The reverse button on the remote control 8 is pressed, and the second motor 57 drives the feed mechanism 56 to move backward. The drill bit 53 begins to withdraw from the cable 55. When the drill bit 53 has completely withdrawn, the reverse button on the remote control 8 is released, and the stop button on the remote control 8 is pressed. The drill bit 53 stops working. The piercing action is completed. At this time, the cable 55 is removed from the cable clamping component 54. If the punctured cable is energized, the current in the energized cable will be conducted sequentially to the drill bit 53, the drill bit clamping part 52, and the power motor 51 at the moment the drill bit 53 punctures the cable, since both the drill bit 53 and the drill bit clamping part 52 are made of metal. This will cause damage to the power motor 51. This proves that the punctured cable is energized, and the cable circuit needs to be further inspected, effectively avoiding injury when checking whether the cable is energized.

[0030] The steps for automatic mode are as follows: Manually place cable 55 into cable clamping component 54, secure cable 55 with locking nut 71, insert battery 7, press power switch (light 3 illuminates), turn on display switch of camera 4 (camera 4 starts working); turn on remote control 8, select automatic mode, press forward button, power motor 1 51 operates, driving drill bit 53 through drill bit clamping component 52; simultaneously, power motor 2 57 operates, driving feed mechanism 56 to move drill bit clamping component 52 forward, thereby moving drill bit 53 as a whole. Moving forward, drill bit 53 begins piercing cable 55. The piercing process is observed on the display screen. When copper shavings are observed flying out, it indicates that the drill bit has made contact with the copper conductor inside cable 55. At this point, press the stop button on remote control 8 to stop the operation, or leave it as is and wait for the piercing device to continue moving forward. When the feed mechanism 56 reaches the set position of the limit block 58, the piercing device will automatically stop moving forward. At this point, press the back button on remote control 8, and drill bit clamping component 52 will move backward. When it returns to the initial position, the operation will stop. The piercing action is complete. At this point, remove cable 55 from cable clamping component 54. Similarly, if the punctured cable is energized, at the moment the drill bit 53 punctures the cable, since both the drill bit 53 and the drill bit clamping component 52 are made of metal, the current in the energized cable will be conducted sequentially to the drill bit 53, the drill bit clamping component 52, and the power motor 51, resulting in damage to the power motor 51. This proves that the punctured cable is energized, and further inspection of the cable circuit is required, effectively avoiding injuries during the inspection of whether the cable is energized.
