Description

Technical Field

[0001] The utility model relates to the technical field of power maintenance equipment, in particular to a convenient grounding mechanism for power lines. Background Art

[0002] Power lines refer to the lines used to transmit electric energy between power plants, substations and power users. It is an important part of the power supply system and is responsible for the transmission and distribution of electric energy. Power lines are conductor loops that connect substations and distribution stations with various electric energy users or electrical equipment, and transmit and distribute electric energy from the power source end (substations and distribution stations) to the load end (electric energy users or electrical equipment).

[0003] A portable grounding mechanism, also known as a portable grounding device, is a device used to prevent electrical accidents. It can ground electrical equipment to the outside world, reduce the electrical pressure of the equipment, and ensure the safety of personnel and equipment. However, the existing grounding mechanisms used for maintenance are usually inconvenient to use, have too simple structures, cannot cope with different use environments, and are easy to loosen during use, resulting in inconvenience in use. Based on this, we propose a portable grounding mechanism for power lines. Utility Model Content

[0020] The working principle of the above technical solution is as follows: when in use, the user carries the device to the working position, and then connects the connecting piece 8 to the device that needs to be grounded, and then places it on the ground. On the smooth ground, the support frame 3 is pulled to drive the plastic slide bar 2 to move up, and the sealing piston 20 is pulled up, so that the suction cup 13 and the straight cylinder 10 that are in contact with the ground form a negative pressure, and are adsorbed on the ground, and then the U-shaped bolt 9 is inserted into the inside of the positioning hole 5, and the U-shaped bolt 9 is located at the bottom of the support frame 3, so that the position of the support frame 3 is stabilized, which is convenient for stabilizing the overall structure and insulating. The spring 15 applies elastic force to the annular support leg 17 and drives the insulating outer tube 16 and the annular support leg 17 to move downward, so that the annular support leg 17 and the conductive column 18 can touch the ground. The grounding current is transmitted to the grounding cable 7 through the connecting piece 8, transmitted to the conductive column 18 through the connecting wire 19, and transmitted to the ground through the conductive column 18 and the annular support leg 17 for grounding. The setting of the insulating plate 1 facilitates the limit protection of the grounding position to prevent the operator from touching the conductive column 18 and being electrocuted, thereby increasing the overall use effect, increasing stability, and reducing looseness.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the insertion rods 11 are evenly distributed at the bottom of the support ring 21 in a circular shape, a reinforcement ring is fixedly installed on the outer side of the insertion rods 11, and the serrations 12 are evenly distributed on both sides of the insertion rods 11 in a linear shape.

[0022] By means of the provided saw teeth 12, when working outdoors on loose soil, the sliding support ring 21 can drive the insertion rod 11 to move downward, so that the insertion rod 11 is stuck in the ground. The saw teeth 12 increase the friction between the rod and the soil, which is convenient for coping with different usage environments and stable operation. The overall structure is easy to carry, stable in operation, easy to operate and has a good use effect.

[0023] In another embodiment, Figure 1-Figure 4 As shown, the plastic sliding rod 2 movably penetrates the insulating plate 1 and extends to the top of the insulating plate 1 .

[0027] In another embodiment, Figure 1-Figure 4As shown, the conductive column 18 is slidably sleeved inside the insulating hollow inner tube 14 , and the conductive column 18 is fixedly sleeved inside the annular support leg 17 .

[0028] The conductive column 18 and the annular support leg 17 can stably contact the ground, so that the annular support leg 17 or the conductive column 18 can also contact the ground on an uneven ground, thereby increasing the stability of grounding and increasing safety.

[0029] In another embodiment, Figure 1-Figure 4 As shown, the insulating spring 15 is sleeved on the outside of the insulating hollow inner tube 14 and the insulating outer tube 16 , and the top end of the insulating spring 15 is fixedly mounted on the bottom of the insulating plate 1 .

[0030] The insulating spring 15 slides under the limit of the insulating hollow inner tube 14 and the insulating outer tube 16, so that the annular support foot 17 maintains the elastic force to move downward, so that the annular support foot 17 and the conductive column 18 are guaranteed to be in contact with the ground, whether the ground is flat or uneven, so that the annular support foot 17 and the conductive column 18 can stably contact the ground, and the use effect is good.
