Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and in particular to an intelligent ground wire monitoring device. Background Art

[0002] The grounding wire is a temporary device used to prevent sudden power supply to equipment and lines, eliminate induced voltage, and discharge residual charge. When the overhead line is shut down, operators often blindly remove the grounding wire or change the position of the grounding wire without authorization, causing personal injury accidents to operators. The existing grounding wire can generally only be installed with the supervision of the leader on site or the operators' own compliance with the operating specifications. This manual method is prone to mistakes, resulting in safety accidents, and manual on-site supervision also wastes labor.

[0003] To this end, technicians in the relevant technical field have made improvements to this. For example, the existing Chinese invention patent with application publication number CN111598272A was published on August 28, 2020. It discloses an intelligent ground wire monitor and monitoring system based on the Internet of Things, which can grasp whether the on-site operation is connected to the ground wire, effectively ensuring the safety of personnel operations. However, during the use of this technology, on the one hand, when the metal frame is placed on the transmission line, it is necessary to rotate the insulating rod to make the screw rotate in order to drive the clamp arm to move upward to clamp the transmission line, thereby connecting the ground wire to the transmission line. Since the transmission line is generally high, it is not only troublesome to operate, but also time-consuming and laborious; on the other hand, the length of the insulating rod of this technology is relatively fixed. Since the height of the transmission line at different locations is different, the length of the insulating rod cannot be adjusted according to the actual situation, which is not convenient for the staff to use and has certain limitations.

DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0030] Example

[0031] Please refer to Figure 1-Figure 6 This embodiment provides an intelligent ground wire monitoring device, including a hook 1 and an insulating rod. The hook 1 is provided with an inlet and outlet 2 and a ground wire 5. The hook 1 is used to be hung on the transmission line, and the hook 1 is made of metal material. A slider 3 is provided on the inner side wall of the top of the hook 1 to slide in the vertical direction, and the bottom of the slider 3 is located outside the hook 1; a pressure sensor 4 is provided inside the hook 1, and the pressure sensor 4 is located directly above the slider 3; the pressure sensor 4 is used to detect whether the hook 1 is hung. When the hook 1 is hung on the transmission line, the slider 3 is pushed upward by the transmission line, and at this time the slider 3 abuts against the pressure sensor 4, and the pressure on the pressure sensor 4 changes. At this time, the pressure sensor 4 transmits an electrical signal to the processor.

[0032] The insulating rod includes an outer sleeve 6 and a sliding rod 7 whose top is slidably arranged in the outer sleeve 6. The top of the outer sleeve 6 is arranged at the bottom of the hook 1. The outer sleeve 6 and the sliding rod 7 are both made of insulating materials. A processor, a battery 8, and a wireless communication module are arranged in the outer sleeve 6. The battery 8, the wireless communication module, and the pressure sensor 4 are all electrically connected to the processor; it also includes a control terminal, which is wirelessly connected to the wireless communication module. A gyroscope module 13 is arranged in the outer sleeve 6, and the gyroscope module 13 is electrically connected to the processor. The processor of this embodiment can adopt an AT89S51 chip, the wireless communication module can adopt a 5G module, and the control terminal can adopt a mobile phone, a computer, or other devices that can view information and send instructions. The gyroscope module 13 is used to detect the overall inclination angle of the insulating rod and transmit it to the processor.

[0033] In some embodiments, the hook 1 is provided with a driving motor 10, and the transmission shaft of the driving motor 10 is provided with a blocking rod 9 for blocking the inlet and outlet 2; the driving motor 10 is electrically connected to the processor. The driving motor 10 is used to drive the blocking rod 9 to rotate under the control of the processor. In a normal state, the position of the blocking rod 9 is as follows: Figure 2As shown, it is convenient for the hook 1 to be hung on the transmission line; when the hook 1 is hung on the transmission line, the processor controls the drive motor 10 to drive the stop rod 9 to rotate to Figure 1 As shown, at this time, the inlet and outlet 2 of the hook 1 is blocked by the blocking rod 9 to prevent the hook 1 from being removed.

[0034] In some embodiments, a limit block 11 is provided on the side wall of the slider 3, a limit slot 12 is provided in the hook 1, and the limit block 11 is slidably arranged in the limit slot 12. The present invention prevents the slider 3 from falling out of the hook 1 by providing the limit block 11 and the limit slot 12.

[0035] In actual use, the staff holds the insulating rod and hangs the hook 1 on the transmission line through the position of the inlet and outlet 2, and grounds the ground wire 5. At this time, the transmission line abuts against the bottom of the slider 3. Under the action of gravity, the slider 3 is pushed upward until it abuts against the pressure sensor 4. The pressure sensor 4 sends a corresponding electrical signal to the processor, and at the same time, it is wirelessly transmitted to the control terminal through the wireless communication module, and the staff of the control terminal knows that the device has been hung on the transmission line. At the same time, the gyroscope module 13 transmits the inclination angle of the insulating rod to the control terminal in real time through the processor and the wireless communication module. After the hook 1 is hung and the ground wire 5 is placed, the insulating rod is suspended on the transmission line. At this time, the transmission line is generally placed vertically. When the staff determines through the control terminal that the inclination angle of the insulating rod is within the set range and basically no longer changes, combined with the detection value of the pressure sensor 4, after the two items meet the requirements at the same time, the staff sends an electrical signal to the processor through the control terminal, and the processor controls the drive motor 10 to drive the blocking rod 9 to rotate and block the inlet and outlet 2. At this time, the hook 1 cannot be removed from the transmission line. The staff at the control terminal can notify the on-site construction personnel that they can start construction, thereby effectively ensuring the safety of equipment and personnel during the maintenance work and improving the reliability of the operation.

[0036] When it is necessary to remove the ground wire monitoring device, after the staff at the control terminal and the on-site maintenance work have ensured that there are no errors, the staff wirelessly sends an electrical signal to the processor through the control terminal. The processor controls the drive motor 10 to drive the barrier rod 9 to rotate and expose the inlet and outlet 2, and the hook 1 can be removed for maintenance work.

[0037] like Figure 1 As shown, in some embodiments, a GPS module 14 is provided in the outer sleeve 6, and the GPS module 14 is electrically connected to the processor. The present invention provides the GPS module 14 to facilitate positioning of the ground monitoring device through the GPS module 14, thereby facilitating the staff to understand the specific location of the ground monitoring device.

[0038] like Figure 1-Figure 2As shown, in some embodiments, a clamping plate 15 is provided on the side wall of the hook 1, and the ground wire 5 is clamped between the clamping plate 15 and the side wall of the hook 1. A locking bolt 16 is also included, and the locking bolt 16 passes through the clamping plate 15 and is threadedly connected to the side wall of the hook 1. The present invention is convenient for fixing the clamping plate 15 and the ground wire 5 to the side wall of the hook 1 through the locking bolt 16, and also convenient for taking out the ground wire 5.

[0039] like Figure 1-Figure 6 As shown, in some embodiments, a plurality of locking grooves 17 are evenly spaced along the vertical direction on the inner wall of the outer sleeve 6, the interior of the sliding rod 7 is hollow, and a locking latch 18 and a button 19 are provided on the sliding rod 7 for sliding along the horizontal direction; the locking latch 18 is located above the button 19, and one end of the locking latch 18 is slidably embedded in a locking groove 17, and one end of the button 19 is located outside the sliding rod 7; an upper paddle 20 is fixedly provided on the outer wall of the locking latch 18, and a lower paddle 21 is fixedly provided on the outer wall of the button 19, and both the upper paddle 20 and the lower paddle 21 are located inside the sliding rod 7; a linkage rod 23 is provided inside the sliding rod 7 for rotation through a rotating shaft 22, and the top of the linkage rod 23 abuts against the upper paddle 20, and the bottom of the linkage rod 23 abuts against the lower paddle 21.

[0040] An upper limit sleeve 24 and a lower limit sleeve 25 are provided on the inner side wall of the sliding rod 7, one end of the locking pin 18 is slidably embedded in the upper limit sleeve 24, and one end of the button 19 is slidably embedded in the lower limit sleeve 25. An upper spring 26 is provided in the upper limit sleeve 24, one end of which is connected to the inner side wall of the sliding rod 7, and the other end of which is connected to the locking pin 18; a lower spring 27 is provided in the lower limit sleeve 25, one end of which is connected to the inner side wall of the sliding rod 7, and the other end of which is connected to the button 19.

[0041] The present invention provides a button 19, and when the length of the insulating rod as a whole needs to be adjusted, the staff can press the button 19, such as Figure 3-Figure 5 As shown, the button 19 drives the lower paddle 21 to slide to the left, and at this time, the lower paddle 21 pushes the linkage rod 23 to rotate a certain distance along the pointer, and the top of the linkage rod 23 pushes the upper paddle 20 and the locking latch 18 to slide to the right. At this time, the end of the locking latch 18 can move out of the locking groove 17. After losing the restriction of the locking latch 18, the outer sleeve 6 and the sliding rod 7 can be freely slid to adjust the relative position of the outer sleeve 6 and the sliding rod 7. After adjusting the overall length of the insulating rod, release the button 19, and under the elastic force of the upper spring 26 and the lower spring 27, the button 19 can be pushed to slide to the right to reset, and the locking latch 18 can be pushed to slide to the left and embedded in a locking groove 17 at the corresponding position to lock. In this way, the outer sleeve 6 and the sliding rod 7 can be fixed by the locking latch 18, which is convenient for the use of the insulating rod after the length is adjusted.
