[0002] In power construction, electrical equipment maintenance and other work scenarios, grounding protection is an indispensable key link to ensure the safety of operators and prevent electric shock accidents. As a component that forms an electrical connection with the earth, the grounding rod needs to be inserted into the ground to a certain depth to ensure a good grounding effect.

[0003] Traditional grounding rods also present inconveniences during transport and storage: due to their sharp tips, they are prone to damage to themselves and other items in the transport vehicle during transportation. Therefore, we have made improvements and proposed a construction safety grounding protection device. Utility Model Content

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-3 A construction safety grounding protection device includes a grounding rod 1 and a protective cylinder 2. The bottom of the protective cylinder 2 has a notch 201, and the top of the grounding rod 1 is inserted into the notch 201. The bottom end of the grounding rod 1 has a pointed tip 104. A fixing component is provided between the protective cylinder 2 and the grounding rod 1. The grounding rod 1 and the protective cylinder 2 are detachable. When the protective cylinder 2 is connected to the top of the grounding rod 1, it can be used by the operator to hold and use, making it easy to insert the grounding rod 1 into the ground. When transporting and storing, the grounding rod 1 can be separated from the protective cylinder 2, and the grounding rod 1 can be put into the protective cylinder 2. At this time, the pointed tip 104 is completely wrapped inside the protective cylinder 2, which avoids accidental injury to the surrounding personnel due to random placement, and also prevents the pointed tip 104 from colliding and scratching with other objects, reducing the possibility of damage to the objects.

[0027] Furthermore, the fasteners include a first through hole 101 on the grounding rod 1 and a third through hole 202 on the protective cylinder 2. A hand-tightening bolt 204 is inserted between the third through hole 202 and the first through hole 101. By passing the hand-tightening bolt 204 through the first through hole 101 and the third through hole 202, the grounding rod 1 and the protective cylinder 2 can be fixed together. The hand-tightening bolt 204 does not require any additional tools, and the operator can tighten or loosen it directly by hand. The first through hole 101 and the third through hole 202 provide a positioning and through path for the hand-tightening bolt 204.

[0028] Furthermore, a nut 203 is threaded onto the hand-tightening bolt 204, and the nut 203 is located on the side of the protective cylinder 2. The nut 203 and the hand-tightening bolt 204 are engaged by threads, generating friction and axial pressure when tightened, forming a reliable limiting structure.

[0029] Furthermore, the top of the grounding rod 1 is provided with an arc-shaped slope 105, and the curvature of the arc-shaped slope 105 is adapted to the curvature of the inner wall of the protective cylinder 2. After the arc-shaped slope 105 passes through the notch 201, it abuts against the inner wall of the protective cylinder 2, thereby increasing the contact area between the two.

[0030] Furthermore, a spiral plate 103 is fixedly connected to the outer surface of the grounding rod 1, and the spiral plate 103 is located at the end of the grounding rod 1 near the tip 104. The spiral plate 103 is spirally arranged. During the rotation process, the spiral structure of the spiral plate 103 uses the principle of spiral transmission to convert the rotational force into a downward axial force, just like a screw being screwed into an object. This makes it easier to screw the grounding rod 1 into the ground. Compared with simply relying on manual pressing to insert, it is more labor-saving and efficient.

[0031] Furthermore, a second through hole 102 is provided on the grounding rod 1. The second through hole 102 is used to connect the grounding wire. When in use, the grounding wire can be tied together with the grounding rod 1 after passing through the second through hole 102. When not in use, the grounding wire can be untied and separated from the second through hole 102.

[0032] Furthermore, the spiral plate 103 is located between the second through hole 102 and the tip 104, and the grounding rod 1 is inserted to a depth less than the distance between the second through hole 102 and the tip 104 during use.

[0033] Furthermore, the grounding rod 1, the tip 104, and the spiral plate 103 are all made of stainless steel, and the grounding rod 1, the tip 104, and the spiral plate 103 are welded together. Stainless steel is corrosion resistant and easy to use.

[0034] Furthermore, the protective cylinder 2 is also made of stainless steel, and the protective cylinder 2 is welded together with the nut 203.

[0035] Furthermore, the outer wall of the protective cylinder 2 is provided with a fluorescent coating. The fluorescent coating can serve as a warning in low light conditions and reduce accidental contact by personnel. The fluorescent coating is made of commercially available fluorescent paint. This application is not an improvement on the composition of existing fluorescent paint, and the specific composition of the fluorescent coating will not be described in detail.

[0036] When using, refer to Figure 1 Insert the tip 104 into the ground, hold the protective cylinder 2 and rotate it. The protective cylinder 2 will drive the grounding rod 1 to rotate. During the rotation, the grounding rod 1 will be screwed into the ground by the spiral plate 103. After use, rotate the protective cylinder 2 in the opposite direction to make the grounding rod 1 unscrew from the ground. Clean off any remaining dirt. Rotate the hand-tightening bolt 204 to separate it from the nut 203, the third through hole 202, and the first through hole 101. Then insert the grounding rod 1 into the protective cylinder 2, aligning the second through hole 102 with the third through hole 202. Then pass the hand-tightening bolt 204 through the third through hole 202 and the second through hole 102 and connect it to the nut 203. Figure 4As shown, the overall structure is more compact at this time, making it easier to carry and store. The grounding rod 1, spiral plate 103 and tip 104 are protected by the protective cylinder 2. When using it again, unscrew the hand-tightening bolt 204, then take out the grounding rod 1, insert the top of the grounding rod 1 into the notch 201 and then fix it with the hand-tightening bolt 204 and nut 203.
