Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and specifically designs a grounding device for a grounding wire. Background Art

[0002] According to the "Electrical Safety Work Regulations", when the 10kv distribution lines and equipment are shut down for maintenance, the measures of "power outage, electricity testing and installation of grounding wires" must be implemented to ensure safety. The grounding wire (i.e. grounding device) is the wire that directly connects the line or equipment to the earth, and can also be called a safety return line. When there is danger, it directly transfers the high voltage to the earth, serving as a lifeline for the safety of front-line employees in power production.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN216529400U discloses a discharge device for power grid maintenance. When in use, the operator plugs the plug-in rod into the ground, and inserts the reinforcement rod on the plug-in rod together with the plug-in rod into the ground. Then, the control component drives the plug-in rod to flip, so that the reinforcement rod is inserted horizontally into the ground to prevent the plug-in rod from being pulled out. The operator then connects the wire to the plug-in rod through the connecting component, so that the electricity on the wire is directed to the ground, thereby improving the grounding effect of the wire. However, when the plug-in rod is loose or pulled out, it is difficult to adjust the direction in time, thereby affecting the construction safety.

[0004] Therefore, it is necessary to design a grounding device for the grounding wire that can dynamically detect the plug-in status of the plug-in rod and promptly detect when it is loose or pulled out, thereby improving construction safety to solve the current technical problems.

[0023] like Figures 1 to 6As shown, the grounding device of the grounding wire comprises a grounding plug 1 and a control module 7. The bottom end of the grounding plug 1 is provided with an anti-drop mechanism 2, and a wiring mechanism 3 is provided on one side of the top of the grounding plug 1. An insulating seat 4 is fixedly provided in the middle of the grounding plug 1, and a looseness detection mechanism 5 is arranged in a circular array on the insulating seat 4. The looseness detection mechanism 5 is used to detect whether the bottom of the insulating seat 4 is tightly fitted with the ground. The looseness detection mechanism 5 is connected to the control module 7, and the control module 7 is connected with an alarm module 6. In this embodiment, the grounding device of the grounding wire is grounded by inserting the grounding plug 1 into the ground. The wiring mechanism 3 is used to connect with the grounding wire. The ground needs to be leveled before inserting the grounding plug 1. After the grounding plug 1 is inserted into place, the bottom of the insulating seat 4 is tightly fitted with the ground. At this time, the looseness detection mechanism 5 is connected to the control module 7. All the mechanisms 5 are triggered, and the control module 7 determines that there is no abnormality in the grounding device of the grounding wire after receiving that all the loose detection mechanisms 5 are triggered; when the grounding device of the grounding wire is loose or pulled out, at least one loose detection mechanism 5 is far away from the ground. At this time, the loose detection mechanism 5 far away from the ground is not triggered. When the control module 7 receives that at least one loose detection mechanism 5 is not triggered, it determines that the grounding device of the grounding wire is loose or pulled out, and the control module 7 controls the alarm module 6 to send an alarm signal to remind on-site personnel to pay attention and conduct timely inspections to avoid accidents and improve construction safety; after the grounding rod 1 is inserted into the ground, it expands outward from the inside of the ground through the anti-detachment mechanism 2, which can improve the strength of the connection between the grounding rod 1 and the ground to prevent the grounding rod 1 from detaching from the ground.

[0024] In some embodiments, Figure 3 and 4 As shown, the looseness detection mechanism 5 has a support tube 51 fixedly arranged on the top of the insulating seat 4, a guide rod 52 is slidably arranged on the insulating seat 4 along the axis of the support tube, a trigger plate 53 is fixedly arranged at the bottom end of the guide rod 52, and a travel switch 55 corresponding to the top of the guide rod 52 is arranged on the inner top of the support tube 51, and the travel switch 55 is connected to the control module 7; when the insulating seat 4 is tightly fitted to the ground, the ground pushes the trigger plate 53, and the trigger plate 53 drives the guide rod 52 to move upward, so that the end of the guide rod 52 triggers the travel switch 55; when the grounding plug 1 is loose or tilted, a gap is generated between the insulating seat 4 and the ground, and under the action of gravity, the guide rod 52 and the trigger plate 53 move downward, and the upper end of the guide rod 52 is separated from the travel switch 55, so that the travel switch 55 is released and no longer triggered.

[0025] In some embodiments, a limit plate 54 corresponding to the inner bottom of the support tube 51 is fixedly provided on the outer side of the guide rod 52, and a stop edge 56 is fixedly provided on the inner middle part of the support tube 51. The stop edge 56 is connected to the inside of the support tube 51 to form an integrated structure, and a spring 55 is sleeved on the outer side of the guide rod 52 between the stop edge 56 and the limit plate 54. The elastic force of the spring 55 can accelerate the reset of the guide rod 52 after the insulating seat 4 is separated from the ground. It should be noted that the elastic force of the spring 55 should not be selected to be too large to avoid the spring 55 pushing the guide rod 52 and the trigger plate 53 to affect the close fit between the insulating seat 4 and the ground.

[0026] In some embodiments, the insulating seat 4 is a circular plate structure made of bakelite material fixedly mounted on the outside of the grounding rod 1. The insulating seat 4 provides support for the loosening detection mechanism 5 and can prevent the current in the grounding rod 1 from being transmitted to the loosening detection mechanism 5, thereby affecting the normal operation of the loosening detection mechanism 5.

[0027] In some embodiments, Figure 5 As shown, the anti-drop mechanism 2 has a moving seat 26 slidably arranged on the inner side of the lower end of the grounding plug 1, and at least two expansion rods 23 are arranged in a circular array on the outer side of the moving seat 26. The bottom end of the expansion rod 23 is hinged to the moving seat 26, and a connecting rod 25 opposite to the expansion rod 23 is hinged to the outer side of the grounding plug 1. The end of the connecting rod 25 away from the grounding plug 1 is slidably connected to the expansion rod 23. The inner thread of the grounding plug 1 is connected with a screw rod 21, and the bottom end of the screw rod 21 is rotatably connected to the moving seat 26. The top end of the screw rod 21 is provided with a hand wheel 22. The screw rod 21 is rotated, and the screw rod 21 cooperates with the grounding plug 1 through the threaded structure, driving the screw rod 21 to move up and down relative to the grounding plug 1 inside it, thereby driving the moving seat 26 to move up and down inside the lower end of the grounding plug 1. When the moving seat 26 moves up and down, it drives the lower end of the expansion rod 23 to move up and down, so that the free end of the expansion rod 23 expands outward. When the grounding plug 1 is inserted into the ground, the expansion rod 23 in the anti-slip mechanism 1 opens outward, which can improve the strength of the connection between the grounding plug 1 and the ground, and prevent the grounding plug 1 from detaching from the ground.

[0028] In some embodiments, as a specific connection method between the connecting rod 25 and the expansion rod 23 , a sliding sleeve 24 is hingedly connected to one end of the connecting rod 25 away from the grounding plug 1 , and the sliding sleeve 24 is sleeved on the outer side of the expansion rod 24 .

[0029] In some embodiments, the wiring mechanism 3 has a terminal post 31 vertically fixedly connected to the grounding plug 1. The terminal post 31 and the grounding plug 1 are connected to form an integrated structure, which is conducive to current transmission. The grounding wire is connected to the terminal post 31.

[0030] In some embodiments, a wiring hole 32 is opened along the radial direction of the terminal post 31, and a locking bolt 33 is provided along the axis of the terminal post 31 at one end away from the grounding plug rod 1, and the end of the locking bolt 33 corresponds to the wire insertion hole 32. The grounding wire is inserted into the inside of the wiring hole 32, and then the locking bolt 33 is screwed so that the end of the locking bolt 33 is abutted and locked with the grounding wire inside the wiring hole 32, thereby realizing a quick connection between the grounding wire and the terminal post 31.

[0031] In some embodiments, a cone head 11 is provided at the bottom end of the grounding rod 1, and the cone head 11 can be used to facilitate the insertion of the grounding rod 1 into the ground.

[0032] In some embodiments, the alarm module 6 is an audible and visual alarm. When the grounding device of the grounding wire is loose or unplugged, the control module 7 controls the audible and visual alarm to send out an audible and visual alarm signal to alert on-site personnel and conduct timely inspections to avoid accidents. The control module 7, the alarm module 6 and the looseness detection mechanism 5 are all powered by secondary batteries.
