Description

Technical Field

[0001] The invention belongs to the technical field of electric power production safety tools, and in particular relates to a cable piercing device with a remote control and rotatable angle. Background Art

[0002] With the continuous advancement of urbanization, a large number of overhead distribution lines in urban construction have been gradually moved to underground laying for power supply. On both sides of the city circuit, in the streets and alleys, inside the community, and so on, high-voltage and low-voltage cables are running everywhere below the ground. The increasing number of equipment, coupled with the long operation time of equipment, inadequate operation management and maintenance, and the increased frequency of urban road construction excavation, have also led to a series of external force damage events. In response to this phenomenon, our power repair construction personnel immediately need to be put into the on-site fault repair state. In the complex underground pipeline well, a large number of cables are intertwined, and it is impossible to distinguish which one is the target cable we need to repair. This is the most important problem facing us.

[0003] In response to the difficult issues raised above, some solutions have also appeared on the market for the large number of cables in the cable well. Although the target cables have been initially identified by instruments, before they are handed over to the emergency repair personnel to officially start work, a destructive test of cable piercing must be carried out before the staff can be allowed to start work, thereby ensuring the absolute personal safety of the work team. In the existing technology, a destructive piercing test is carried out on the target high-voltage cable on site, which helps the maintenance staff to verify whether the target cable has voltage and provide safe guidance for the next step. At present, cable fault maintenance must use cable identification instruments to identify the many cables in the cable trench before disconnecting the cable, and cooperate with DR8000 and D5000 handheld cable path testers to determine the target cable. The above technology can only infer the target cable in theory. Before disconnecting the cable, a safety verification test of the target cable piercing must be carried out. Traditional piercing tools require two people to operate, and the operator stands next to the cable, which poses a huge safety risk.

[0004] At the same time, after continuous experience summary in field work, we believe that the existing equipment on the market does not have the problem of remote control and automatic rotation of the piercing angle, resulting in the piercing effect is not very ideal; after the first penetration, if the cable core cannot be penetrated or coincidentally penetrated between the two-phase insulation skin, it will create an illusion of no electricity. At this time, if it is judged that the cable is without electricity, it will be irresponsible and dangerous to allow the construction unit to carry out the construction; and the above-mentioned piercing between the two phases destroys the insulation between the two phases. The traditional piercing device requires personnel to approach to disassemble and change the angle and direction. At this time, the cable insulation is weak, and single-phase grounding and phase-to-phase short circuit accidents are very likely to occur, posing a serious threat to the personal safety of the operator. In order to overcome this technical defect, after continuous observation and understanding, a remote control and rotatable angle cable piercing device invention is proposed, which is convenient for power cables to be pierced before on-site emergency repairs and maintenance, and eliminates blind judgment of the target cable before construction, thereby causing irreversible personal safety accidents.

The device allows the staff to maintain a safe distance from the piercing device and conduct a piercing test before the inspection or emergency repair of the target cable.

[0034] like Figure 8 As shown, the safety piercing device 60 includes a piercing device housing 61, a threaded shaft housing 62 and a receiving cavity 621; the threaded shaft housing 62 is arranged below the piercing device housing 61, and the receiving cavity 621 is arranged below the threaded shaft housing 61; a rotating motor 64 is arranged inside the piercing device housing 61 and a movable groove 641 is reserved, the output shaft of the rotating motor 64 is connected to the threaded shaft nail 65, the end of the threaded shaft nail 65 is provided with a piercing nail head 66, and the receiving cavity 621 is used to protect the piercing nail head 66; the rotating motor 64 can drive the threaded shaft nail 65 to move up and down in the threaded shaft housing 61 and the receiving cavity 621.

[0035] like Figure 8 As shown, a control receiver 63 is provided on the top of the piercing device housing 61 for receiving instructions from the controller 90, and the control receiver 63 is electrically connected to the rotating motor 64; the control receiver 63 is connected to a buzzer alarm or a power display, and a power node port 631 and a ground connection terminal 632 are provided on the outside of the control receiver 63, the power node port 631 is used for power supply, and the ground connection terminal 632 is used for connecting the grounding component 80.

[0036] Specifically, the ground connection terminal 632 is connected to the housing of the control receiver 63 . Since the housing of the control receiver 63 , the housing of the rotating motor 64 , etc. are all made of metal, the current can be conducted into the ground through the grounding component 80 .

[0037] Specifically, when the safety piercing device 60 pierces the cable to be tested, the buzzer alarm or the live indicator moves toward the cable to be tested along with the control receiver 63. If the cable to be tested is not powered off, the buzzer alarm or the live indicator will emit an alarm sound or an alarm light by sensing the current, thereby knowing whether the cable to be tested is live (if the buzzer alarm or the live indicator is not provided, it can also be judged by electric sparks).

[0038] Specifically, in one embodiment, the model of the buzzer alarm is YJ-AM-3.

[0039] like Figure 5 , 8 As shown, a combination slot 541 is provided inside the semicircular clamp 54, and a corresponding combination insert plate 67 is provided on the piercing device housing 61 of the safety piercing device 60. When the semicircular clamp 54 is used to clamp the safety piercing device 60, the combination insert plate 67 is embedded in the combination slot 541 to fix the safety piercing device 60.

[0040] Specifically, since the safety piercing device 60 will be subjected to an upward reaction force from the cable outer shell or inner core when piercing the cable to be tested, the safety piercing device 60 can be firmly fixed between the first assembly shell 10 and the second assembly shell 20 through the mutual cooperation of the combination plug-in plate 67 and the combination slot 541 to prevent it from falling out.

[0041] like Fig. 9 As shown, the grounding assembly 80 includes a grounding rod 81 , a grounding wire 82 and a grounding wire connector 83 ; the grounding wire connector terminal 632 is connected to the grounding wire connector 83 , and the grounding wire connector 83 is connected to the grounding rod 81 through the grounding wire 82 .

[0042] like Figure 4 , 6 As shown in Figures 7 and 8, in one embodiment, a receiving groove 12 is provided on both sides of the first assembly shell 10 and the second assembly shell 20, a self-locking nut 45 is provided on both sides of the first assembly shell 10, and a ball screw 41 is provided at the corresponding position on both sides of the clamp base 30, and an adjusting knob 42 is provided at the end of one of the ball screws 41; a transmission wheel 43 is provided on the outer side of each of the two ball screws 41, and transmission is achieved between the transmission wheels 43 through a tensioning belt 44.

[0043] like Figure 5 , 6 A roller 55 is arranged between the sector-shaped rotating disk 52 and the arc-shaped slide groove 11, and the arc-shaped slide groove 11 is provided with a limited position pit.

[0044] Specifically, the roller 55 is arranged in the fan-shaped rotating disk 52 through an elastic element, and there is pressure on the arc-shaped slide groove 11. The roller 55 is evenly distributed at a preset angle or preset spacing, and the pits are also evenly distributed at a preset angle or preset spacing; when the tester adjusts the angle of the safety piercing device 60 through the angle adjustment mechanism 50, the servo motor 51 drives the fan-shaped rotating disk 52 to rotate, and the roller 55 can just fall into the pit. When the angle needs to be changed again, the fan-shaped rotating disk 52 drives the roller 55 to fall into the pit at the next position. The pits can be set at a preset angle or preset spacing to achieve multi-angle adjustment of the safety piercing device 60.

[0045] The specific use process of this device is as follows:

[0046] (1) Turn the adjusting knob 42 to rotate the ball screw 41 out of the self-locking nut 45, thereby separating the device housing and the fixture chassis 30;

[0047] (2) Place the arc-shaped openings of the device housing of the cable to be tested and the fixture chassis 30 at corresponding positions, and turn the adjustment knob 42 so that the device housing and the fixture chassis 30 clamp the cable to be tested;

[0048] (3) The tester remotely controls the rotation motor 64 through the controller 90. Since a movable groove 641 is provided inside the piercing device housing 61, the threaded shaft nail 65 can drive the piercing nail head 66 to move downward to pierce the cable to be tested.

[0049] (4) Determine whether the cable is energized by using a buzzer alarm, a live display, or observing electric sparks. At this time, the tester is at a distance, which can ensure the safety of the personnel;

[0050] (5) The threaded pin 65 is retracted by the controller 90, and the servo motor 51 is remotely controlled by the controller 90 to change the angle of the fan-shaped rotating disk 52, thereby changing the piercing angle of the safety piercing device 60;

[0051] (6) Perform multiple tests to obtain test results - charged or not charged.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
