Description

Technical Field

[0001] The present invention relates to the field of line maintenance tools, and particularly to a novel grounding wire device and an operation method. Background Art

[0002] The 220kV distribution network overhead line is one of the high-voltage power lines most commonly used in urban and rural distribution networks in China. It is responsible for delivering electricity to the terminals of industrial, commercial, and residential electricity users. It has the characteristics of long transmission line mileage and many nodes. To ensure the stable operation of the 220kV distribution line, regular inspections and maintenance are required. The operation site of operation and maintenance inspection must strictly carry out standardized operations of power outage, voltage testing, grounding, hanging warning signs, and installing barriers (fences). It is mainly implemented through various monitoring terminals and the cooperation of the person in charge of live working to conduct on-site and remote safety control.

[0003] Currently, the Chinese invention with the publication number CN107508058B discloses a high-voltage grounding rod. Although the grounding rod has a good contact effect with the metal wire during use and can be adjusted adaptively in terms of angle, there are still other problems in the use process. For example, the degree of digitization and intelligence is relatively low, and it can only be used and managed in a relatively rough manner. During on-site operations, it is easy to have operational negligence. In the case of human judgment, it will affect the occurrence of personal safety accidents. Moreover, it does not have a retractable adjustment function. The holding and supporting parts below the device need to be set longer so that personnel can easily hang it on the wire from below during use. However, since its holding rod is integrally formed, although it has high strength, it is difficult to carry and transport. It will not only occupy too much space but also be difficult to pass through narrow sections smoothly, and its flexibility is poor. To solve the above problems, we propose a novel grounding wire device and an operation method. Summary of the Invention

[0004] The purpose of the present invention is to provide a novel grounding wire device and an operation method, which solve the problems that the existing device is difficult to accurately judge whether it is properly hung and does not have a retractable adjustment function.

[0005] The above technical object of the present invention is achieved through the following technical solutions: A new type of grounding wire device includes a housing.

[0011] The present invention is further configured such that: a guide rod is welded to the top of the mounting frame, a through hole is formed in the top of the fixing frame, and the other end of the guide rod penetrates and extends to the top of the through hole.

[0012] With the above technical solution, through the arrangement of the guide rod and the through hole, the mounting frame can be limited, preventing the mounting frame from tilting when it moves upward under force, and improving the stability of the mounting frame during the up and down movement.

[0013] The present invention is further configured such that: wiring terminals and grounding terminals are respectively installed at both ends of the grounding wire, a second screw is welded to one side of the first connecting member, the wiring terminal is slidably sleeved on the surface of the second screw, a wing nut is threadedly connected to the surface of the second screw, and both the second screw and the wing nut are made of stainless steel.

[0015] The present invention is further configured such that: a buzzer is installed through the front surface of the housing, a push switch is installed through the front surface of the housing and above the buzzer, and the connection ends of the buzzer and the push switch are both connected to the circuit board.

[0016] The present invention is further configured such that: a spring washer is slidably sleeved on the surface of the first screw, and the spring washer is located between the connecting seat and the fixing nut.

[0017] With the above technical solution, through the arrangement of the spring washer, the fixing effect of the fixing nut after being tightened can be improved, playing a role in shock prevention and loosening prevention.

[0018] The present invention is further configured such that: an anti-slip sleeve is fixedly sleeved on the surface of the holding rod, and the anti-slip sleeve is made of neoprene.

[0019] With the above technical solution, through the arrangement of the anti-slip sleeve, the frictional force between the human hand and the holding rod can be increased, preventing the hand from slipping during the upward lifting process.

[0020] The present invention is further configured such that: the surfaces of the housing, the fixing frame, the first connecting member and the second connecting member are all coated with an anti-corrosion coating.

[0021] With the above technical solution, through the arrangement of the anti-corrosion coating, the anti-corrosion and moisture-proof effects of the surfaces of the housing, the fixing frame, the first connecting member and the second connecting member can be improved, and the service life of the housing, the fixing frame, the first connecting member and the second connecting member is prolonged.
