Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It can be understood by those skilled in the art that the features in the following embodiments and implementations can be combined with each other without conflict.

Referring to Figure 1, a grounding wire assembly with real-time power inspection function includes:

A grounding clip 1, the grounding clip includes a clip 11, a ground wire group connected to the clip, and a connector 15, the ground wire set is connected to a ground pin, the clip includes a U-shaped portion (inverted) and There are two oppositely arranged elastic splints 12 on the inner sides of the two sides of the U-shaped portion, and the connecting head 15 is connected to one side of the mouth of the U-shaped portion;

The insulating operating rod 2, the upper end of the insulating operating rod is connected to the connecting head 15 of the wiring clip, and the lower part of the insulating operating rod is installed with an operating handle;

Electroscope, the electroscope includes a copper wire 31 and an induction alarm module 32, one end of the copper wire 31 is connected to the induction alarm module 32, and the other end is connected to the clip 11 of the grounding clamp.

The grounding clamp is a commonly used equipment in the maintenance of high-voltage transmission lines. The grounding clamp is generally composed of a clamp, a connecting rod, a grounding wire group and a grounding pin. The traditional grounding clip has greatly improved the work efficiency. In order to ensure reliable grounding and convenient use, the grounding components of the grounding clip are analyzed, and the safe, reliable and efficient use of the grounding clip is discussed. It is concluded that the staff must use the electric inspection rod to conduct electricity inspection before using the grounding clip to work, and then the grounding operation can be carried out. Therefore, the grounding wire device with the functions of early warning and electric inspection designed by the present invention simplifies the work process to a certain extent and improves the work safety factor.

The traditional electric inspection rod is composed of the rod body, the alarm, the indicator light, the contact contact and the check button. The user holds the handle position and uses the contact to touch the place where the electric inspection is required. It must be carried out separately from the operation of the ground wire. The invention removes the electroscope contacts of the electroscope, abandons the original telescopic rod body of the electroscope, and uses copper wires instead of contacts. One end of the copper wire 31 is connected to the induction alarm module 32, and the other end is connected to the grounding clamp The collet is connected, so that the electric test can be performed at the same time as the grounding operation.

In addition, a near-electrical voice alarm is also included, and the near-electrical voice alarm is installed on the insulating operating rod and is close to the operating handle. The near-electrical voice alarm is fixed on the insulating operating rod with a tie or an adhesive tape. When approaching the high-voltage live area, the induction module of the near-power voice alarm generates a corresponding induced current in the high-voltage alternating electromagnetic field to give an alarm to warn the user. When the user is using the grounding clamp, when the hand is close to the charged body, the near-electric voice alarm will alarm, and the staff will stop the operation, which can improve the safety factor.

The near-power voice alarm adopts the prior art, wherein the induction alarm module includes a body and an induction chip mounted on the body, and the body is fixed to the insulating operating rod by a tie or an adhesive tape.

Wherein, the U-shaped portion is connected with a terminal screw 13 connected with the electrical inspection contact. One end of the wiring group is provided with a wiring copper bar, and the wiring copper bar is fixed on the side of the U-shaped portion by means of fastening screws 14, so as to facilitate the installation of the electrical inspection contacts and the grounding wire group.

Referring to Figure 2, when using, start the electroscope and the near-electrical voice alarm first, and then use the electroscope installed on the grounding clip to conduct the electroscope operation to confirm whether the high-voltage line is live. If the high-voltage line is not live, it can be connected. The electroscope can monitor the live condition of the high-voltage line in real time. If the high-voltage line is not charged, the electroscope does not give a corresponding prompt, and starts to hang the ground wire. First, screw the grounding pin into the ground through the foot pad, and then use the grounding wire to clamp the high-voltage wire. , While hooking up the grounding wire, the electroscope can monitor the high-voltage line in real time to prevent the high-voltage line from being suddenly electrified, and warn the electrician to pay attention to safety; when the high-voltage line is electrified, the electroscope will issue an alarm to warn the electrician to pay attention to safety, and then pass the electroscope of the electroscope. The contact further confirms the electrification of each wire in the high-voltage line. When confirming that the wire is electrified, the buzzer in the electroscope starts to alarm and the flashing light flashes, prompting the electric operator that the line is electrified, thus effectively avoiding the occurrence of the accident of the live hanging ground wire.

An electroscope is installed on the top of the grounding clamp, so that the electrician can conduct electricity inspection at the same time when arranging the grounding wire, which has the "real-time electric inspection function". In addition, a near-electrical voice alarm is installed on the handle of the grounding clamp. When the staff's hand is close to the charged body, it will alarm to remind the staff, which reduces the risk of the staff's work process, and integrates the power inspection and grounding links into one link. On this basis, it can save a lot of time and greatly improve the work efficiency.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
