Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to discharger protection, and in particular to a ground discharger protection component. Background Art
[0002] During distribution network line maintenance, the use of ground discharge devices (such as ground rods) is crucial to ensuring the personal safety of maintenance personnel and equipment. During maintenance, distribution network lines may still be energized or retain residual charge. Connecting the lines to the ground with ground discharge devices effectively conducts the charge away, preventing maintenance personnel from experiencing electric shock from contact with live lines. Ground discharge devices also prevent equipment damage or malfunction caused by charge accumulation, ensuring normal operation after maintenance.
[0003] Working principle and characteristics of grounding rods
[0004] How it works: A ground rod typically contains a conductive material that, when driven into the ground, creates an electrical connection to the earth. When the distribution network line becomes energized, the rod conducts the current, completing a loop through the earth and discharging the charge.
[0005] Features: The ground rod is portable, easy to operate and cost-effective. It is one of the commonly used ground discharge devices in the maintenance of distribution network lines.
[0006] However, there are many problems in the use of grounding rods:
[0007] (1) Contact with external objects: As described in the problem description, the existing grounding rod may lack a protective structure on the outside. This may cause external objects (such as branches, weeds, animals, etc.) to come into contact with the grounding rod, thereby causing current conduction, causing damage to the external objects or posing a safety hazard.
[0008] (2) Position deviation: The movement or collision of external objects may cause the ground rod to deviate from its position, affecting its electrical connection with the earth. This will not only affect the normal discharge work, but also increase the safety risk of maintenance personnel. Utility Model Content
[0009] The technical problem to be solved by the utility model is to provide a grounding discharger protection component, which adds a protection structure to the grounding discharger, can isolate external objects from being damaged by current, improve the safety of the grounding discharger, and effectively prevent the grounding discharger from shifting in position.
[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0012] A further improvement of the technical solution of the present invention is that: the side walls of the protective tube and the sleeve are both provided with viewing openings that are through-and-through, and a transparent cover is installed in the viewing opening.
[0013] A further improvement of the technical solution of the present utility model is that the side wall surfaces adjacent to the sleeve and the protective tube are covered with a smooth layer.
[0014] A further improvement of the technical solution of the present utility model is that the guide mechanism includes a guide groove vertically opened on the side wall of the sleeve, and a guide rod is connected to the side wall of the protective tube corresponding to the position of the guide groove. The guide rod extends into the guide groove, and a baffle is connected to the lower end surface of the guide rod.
[0015] A further improvement of the technical solution of the present utility model is that: a plurality of positioning holes are provided on the side walls of the sleeve and the protective tube, and the positioning pins are inserted into the positioning holes.
[0016] A further improvement of the technical solution of the present utility model is that: the number of the positioning holes is five and they are evenly arranged on the side wall of the protective tube.
[0017] A further improvement of the technical solution of the present utility model is that the fixing buckle is C-shaped as a whole, a positioning frame is connected to the side wall of the sleeve, the fixing buckle is arranged in the positioning frame, and a fixing bolt is threadedly provided on the side wall of the lower end of the fixing buckle, and one end of the fixing bolt is in contact with the side wall of the positioning frame.
[0018] A further improvement of the technical solution of the present utility model is that: the number of the positioning frames is three and they are evenly arranged on the outer edge of the top end of the side wall of the protective tube.
[0019] A further improvement of the technical solution of the present utility model is that: a plurality of pressure plates are connected to the side walls of the sleeve corresponding to the positions of the fixed cones, and the side wall surfaces of the pressure plates are covered with a friction layer.
[0020] A further improvement of the technical solution of the present utility model is that: the number of the pressing plates is three and they are evenly arranged on the surface of the side wall of the sleeve which is not the viewing port.

[0043] A guide mechanism 3 is provided between the sleeve 2 and the side wall of the protective tube 1. The guide mechanism 3 includes a guide groove 301 opened on the side wall of the sleeve 2. A guide rod 302 is connected to the side wall of the protective tube 1 corresponding to the position of the guide groove 301. The guide rod 302 extends into the guide groove 301. The two cooperate to guide the moving direction of the sleeve 2 to ensure the stability of the overall position of the sleeve 2 and avoid deviation.
