[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a power transmission and transformation line installation protection device includes a clamp 1, a grounding rod 2 is arranged on the inner side of the clamp 1, a connecting stud 3 is fixed to one end of the grounding rod 2, a limiting clamp 4 is arranged at one end of the connecting stud 3, a grounding wire 5 is installed at one end of the clamp 1, a grip 6 is arranged at the other end of the grounding rod 2, a functional component is arranged on the surface of the grounding rod 2, the functional component includes a limiting rod 7 arranged on the adjacent side of one side of the grounding rod 2, a fixing groove 8 is opened on one side surface of the grounding rod 2, the length of the limiting rod 7 is equal to the length of the opening of the fixing groove 8, and the width of the opening of the fixing groove 8 is greater than The end surface diameter of the limiting rod 7, a winding rod 9 is symmetrically fixed on one side surface of the limiting rod 7, the cross-section of the winding rod 9 is "L"-shaped, the two winding rods 9 are arranged opposite to each other, and the inner wall of the fixing groove 8 is symmetrically provided with through grooves 11 for the winding rod 9 to pass through, and a limiting spring 10 is sleeved on the outer side of the end where the winding rod 9 is connected to the limiting rod 7, and a limiting strap 12 is provided in the middle of the limiting rod 7, which is convenient for limiting the storage of the grounding wire 5, so that the grounding wire 5 will not be scattered, avoiding damage caused by being stepped on, and also facilitating the storage of the protective device at a later time, and has good practicality.

[0020] like Figure 1 and Figure 3 As shown, a limiting component is provided on the surface of the limiting clamp plate 4, and the limiting component includes a fixing groove 13 opened in the middle of the surface of the limiting clamp plate 4, and a rubber sheet 14 is symmetrically installed at the opening of the fixing groove 13, and a connecting sheet 15 is fixed to the bottom surface of one end of the rubber sheet 14, and a connecting card groove 16 for the connecting sheet 15 to engage is symmetrically opened on the inner bottom surface of the fixing groove 13, and an elastic sheet 17 is installed between the bottom of the other end of the rubber sheet 14 and the inner wall of the opening of the fixing groove 13, and the inner surface of the fixing groove 13 is an arc surface, and the cross section of the elastic sheet 17 is "V"-shaped, and the surface of the rubber sheet 14 is evenly provided with anti-slip protrusions 18, and the cross section of the anti-slip protrusions 18 is an isosceles trapezoid, which is convenient for improving the firmness of the limiting clamp plate 4 and the clamp head 1 to clamp the wire, so that the wire is not easy to loosen after being clamped, thereby increasing the contact area between the limiting clamp plate 4 and the wire, and having a good practical effect.

[0021] The utility model provides a transmission and transformation line installation protection device, the specific working principle is as follows: when the grounding wire 5 needs to be limited and stored, the utility model first presses the surface of the limit rod 7 to make the limit rod 7 move toward the inside of the fixed groove 8. At this time, the limit rod 7 will push the winding rod 9 to move inside the through groove 11, and at the same time, one end of the winding rod 9 will move toward one side of the grounding rod 2. When the limit rod 7 squeezes the limit spring 10, the limit spring 10 will generate a rebound force. Then the worker can wind the grounding wire 5 to the outside of one end of the two winding rods 9 until the grounding wire 5 is wound. The limit rod 7 can be loosened. At this time, the rebound force generated by the limit spring 10 will act on the limit rod 7, so that the limit rod 7 drives the winding rod 9 to move and reset. Then the worker can further bundle the wound grounding wire 5 through the limit strap 12, so that the grounding wire 5 will not be scattered. The operation is convenient and quick, and the device is easy to store, and the practicality is good. When the utility model needs to be connected with the wire, the clamp 1 is first clamped to the outside of the wire, and then the grounding rod 2 is rotated so that the connecting stud 3 at one end of the grounding rod 2 pushes the limiting clamp 4 to approach the surface of the wire. At this time, the anti-skid protrusion 18 on the surface of the rubber sheet 14 will contact the wire, and the rubber sheet 14 will be squeezed and move toward the inside of the fixing groove 13. At this time, the connecting piece 15 at the bottom of one end of the rubber sheet 14 will move toward the inside of the connecting card groove 16 and engage. When one end of the rubber sheet 14 is rotated to fit the inside of the fixing groove 13, the elastic sheet 17 between the other end of the rubber sheet 14 and the inside of the fixing groove 13 will generate a rebound force and act on the rubber sheet 14 until the limiting clamp 4 clamps the wire to the inner side of the clamp 1. At this time, the surface of the rubber sheet 14 will fit closely with the surface of the wire, and the anti-skid protrusion 18 makes it difficult for the wire to get loose, thereby improving the firmness of the limiting clamp 4 and the clamp 1 to clamp the wire, and the practical effect is better.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
