A clamping block 105 is fixedly connected to the inner wall of the two arc-shaped holes 102 on the left and right sides, which are away from each other. The clamping block 105 is movably mounted on the corresponding clamping groove 104. The clamping block 105 cooperates with the clamping groove 104 to position the rectangular protective cover 101. The metal protective coating 6 and the anti-oxidation coating 5 on the copper rod grounding electrode body 3 are movably sleeved on the four clamping blocks 105.

The two first installation boxes 701 are respectively fixedly mounted on the front and rear sides of the rectangular protective cover 101 on the right, and the two second installation boxes 702 are respectively fixedly mounted on the front and rear sides of the rectangular protective cover 101 on the left. An elastic locking sleeve 703 is fixedly connected to the left inner wall of the second installation box 702.

The left side of the locking ball 705 is set to a conical structure 707 that cooperates with the corresponding trumpet-shaped structure 704. The setting of the conical structure 707 is used to squeeze the elastic locking sleeve 703 before the locking ball 705 enters the elastic locking sleeve 703. A connecting block 706 is fixedly connected between the right side of the locking ball 705 and the right inner wall of the corresponding first installation box 701. The connecting block 706 is movably sleeved in the corresponding trumpet-shaped structure 704. The left diameter of the elastic locking sleeve 703 is larger than the right diameter, and the right diameter of the elastic locking sleeve 703 is smaller than the diameter of the locking ball 705. The right part of the elastic locking sleeve 703 is used to restrict and lock the locking ball 705;

[0031] The outer side of the copper rod grounding electrode body 3 is provided with a straightening mechanism 2 for straightening during use. The straightening mechanism 2 includes a straightening sleeve 201 sleeved on the copper rod grounding electrode body 3. Both sides of the straightening sleeve 201 are fixedly connected with mounting plates 202. The top of the mounting plate 202 is provided with a bolt hole. The threaded sleeve in the bolt hole is provided with a T-shaped fixing anchor rod 203. The T-shaped fixing anchor rod 203 can be screwed into the ground to fix the straightening sleeve 201. Two balls 204 are movably embedded on the inner walls of the four sides of the straightening sleeve 201. The copper rod grounding electrode body 3 is located between the multiple balls 204 and movably contacts the multiple balls 204. The straightening sleeve 201 and the multiple balls 204 are in contact with each other. The balls 204 cooperate with each other to straighten the copper rod grounding electrode body 3; the utility model, through a series of structural settings, can form a protective layer on the outside of the copper rod grounding electrode body 3 and the galvanized flat steel 4 through the metal protective coating 6 and the anti-oxidation coating 5 to provide anti-oxidation protection, and can fix the anti-oxidation protection mechanism 1 on the welding part of the copper rod grounding electrode body 3 and the galvanized flat steel 4 by a simple push to seal and shield them, thereby achieving the anti-oxidation effect. In addition, the copper rod grounding electrode body 3 can be vertically guided during use to ensure that the copper rod grounding electrode body 3 is vertically inserted into the ground, avoiding the situation where normal use is affected by the insertion tilt.

[0032] Working Principle: When in use, the metal protective coating 6 and the anti-oxidation coating 5 are matched and arranged on the outside of the copper rod grounding electrode body 3 and the galvanized flat steel 4 to form a protective film layer. This protective film layer can isolate oxygen from entering the copper rod grounding electrode body 3 and the galvanized flat steel 4, thereby preventing the copper rod grounding electrode body 3 and the galvanized flat steel 4 from oxidation, achieving an anti-oxidation effect;

[0033] When the rectangular protective cover 101 is not mounted on the galvanized flat steel 4, after the copper rod grounding electrode body 3 and the galvanized flat steel 4 are welded, the two rectangular protective covers 101 can be mounted on the galvanized flat steel 4. When the rectangular protective cover 101 moves, it drives the corresponding clamping block 105 to be movably mounted in the clamping slot 104. When the rectangular protective cover 101 on the right moves, it also drives the two first installation boxes 701 to move to the left and are respectively mounted on the corresponding second installation boxes 702. The first installation box 701 drives the connecting block 706 and the clamping ball 705 to move to the left in turn. When the clamping ball 705 moves to the left until its conical structure 707 contacts the elastic locking cover 703, the elastic locking cover 703 is squeezed. Under the squeezing force, the right side of the elastic locking cover 703 is deformed and expanded outward. When the clamping ball When 705 moves to the left into the elastic locking sleeve 703, the right side of the elastic locking sleeve 703 is reset to restrict the right side of the locking ball 705. Under the locking force of the elastic locking sleeve 703, the two rectangular protective sleeves 101 can be mutually restricted. At this time, the two rectangular protective sleeves 101 are both fixed on the copper rod grounding electrode body 3 and the galvanized flat steel 4. At this time, the elastic sealing rubber sleeve 103 and the elastic sealing rubber pad on the rectangular protective sleeve 101 are in close contact with the corresponding anti-oxidation coating 5 respectively. At this time, the rectangular protective sleeve 101 cooperates with the elastic sealing rubber sleeve 103 and the elastic sealing rubber pad to seal and shield the welding part of the copper rod grounding electrode body 3 and the galvanized flat steel 4. Through the sealing and shielding protection, the influence of oxygen on the welding part can be effectively reduced, thereby achieving the effect of anti-oxidation protection of the welding part;

[0034] When the rectangular protective cover 101 needs to be removed later, the two rectangular protective covers 101 can be pulled away from each other, and the rectangular protective cover 101 on the right drives the two first installation boxes 701 to move to the right. The first installation box 701 drives the fixing balls 705 to move to the right through the corresponding connecting blocks 706 to squeeze the right part of the elastic locking cover 703. Under the squeezing force, the right side of the elastic locking cover 703 is deformed and expanded outward, so that the fixing balls 705 are moved out of the corresponding elastic locking cover 703, and the mutual restriction of the two rectangular protective covers 101 is released, and the rectangular protective cover 101 can be removed;

[0035] After the two rectangular protective sleeves 101 shield and protect the welding parts of the copper rod grounding electrode body 3 and the galvanized flat steel 4, when the copper rod grounding electrode body 3 needs to be inserted into the ground, the straightening sleeve 201 can be first fixed to the ground by two T-shaped fixed anchor rods 203, and then the copper rod grounding electrode body 3 is inserted between the multiple balls 204 in the straightening sleeve 201, and the copper rod grounding electrode body 3 is continued to be moved downward, so that the copper rod grounding electrode body 3 moves downward along the multiple balls 204 and is inserted into the ground. During the insertion process, the multiple balls 204 cooperate with the straightening sleeve 201 to guide the copper rod grounding electrode body 3, which can ensure that the copper rod grounding electrode body 3 is inserted vertically into the ground, avoiding the situation where normal use is affected by the insertion tilt.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
