DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: An insulator safety shield, such as Figures 1-4As shown, it includes a protective cover body 101 for installation on an insulator for protection. The protective cover body 101 is set to a truncated cone shape with a small upper part and a large lower part. The protective cover body 101 is made of elastic material, and an opening and closing opening 103 is opened on the front side thereof, which is convenient for opening the protective cover body 101 and sleeved on the insulator by an installation tool. The opening and closing opening 103 gradually shrinks from bottom to top. Two left and right sheaths 102 are fixedly connected to one side of the protective cover body 101 near the opening and closing opening 103, which are used to wrap the wires connected to the insulator. Considering that the protective cover body 101 and the sheath 102 are exposed to the natural environment for a long time when used outdoors, the material is set to an insulating weather-resistant material with good ultraviolet resistance, moisture resistance, corrosion resistance and other properties. The top of the protective cover body 101 is connected to a swivel 104 through a bearing, which is fixed with limit buckles 105 symmetrically distributed along itself. When the protective cover body 101 is opened, the limit buckles 105 are squeezed to the protective cover body 1 01 top, when the protective cover body 101 is closed, the limit buckle 105 moves downward to the left and right parts of the outer side surface of the protective cover body 101, which plays the role of tightening the protective cover body 101 to prevent it from opening at will. A prompt cover plate 106 is rotatably connected in the swivel 104. The outer surface of the prompt cover plate 106 is provided with a red color for repelling birds, and is provided with a mirror effect or a material that can strongly reflect light to simulate the sudden appearance of a predator, thereby scaring away the birds. The top of the protective cover body 101 is provided with a plurality of air vents 107 for venting air, and the prompt cover plate 106 blocks the air vents 107 downward, and the bottom of the prompt cover plate 106 is fixed with limit blocks 108 distributed symmetrically along itself, and the middle of the top side of the protective cover body 101 is fixed with a connecting block 109 distributed symmetrically along itself, and a limiting groove for the limit block 108 to be snapped downward is provided between the connecting block 109 and the protective cover body 101.

[0032] like Figure 1-Figure 3 As shown, it also includes lock buckles 201 symmetrically distributed along the left and right sides of the protective cover body 101, which are used to snap into the umbrella skirt structure of the insulator. The lock buckles 201 are fixed to the lower outer side of the protective cover body 101 through reinforcing ribs, and the lock buckles 201 are made of elastic material.

[0033] like Figure 1 and Figure 2 As shown, it also includes a first locking block 301 and a second locking block 302. The first locking block 301 is fixed to the bottom of the sheath 102 on the right side, and the second locking block 302 is fixed to the bottom of the sheath 102 on the left side. When the two sheaths 102 are closed to each other, the first locking block 301 and the second locking block 302 are interlocked.

[0034] This is a protective cover installed on an insulator to prevent tripping caused by bird damage, wind, sun, lightning strikes, aging of insulating components, etc. When in use, the two sheaths 102 are first opened with an installation tool, thereby opening the opening 103 and opening the protective cover body 101. The opened protective cover body 101 presses the upper left and right limit buckles 105 to the top through the outer side surface, thereby causing the rotating ring 104 to rotate upward, and the prompt cover 106 rotates upward with the rotating ring 104. The protective cover body 101 is then moved onto the insulator using the installation tool, and the wires connected to the insulator are passed out from between the two sheaths 102;

[0035] After the installation tool is removed, the protective cover 101 closes under its own resilience, causing the limit buckle 105 to separate from the top of the protective cover 101. At this time, the rotating ring 104 and the prompt cover 106 rotate downward under their own gravity. The left and right limit buckles 105 move downward with the rotating ring 104 to be respectively limited to the left and right parts of the outer side of the protective cover 101, thereby tightening the protective cover 101 and preventing the protective cover 101 from being opened at will and blown away by the wind.

[0036] After the protective cover 101 is closed, the prompt cover 106 covers the vent hole 107 to form a closed protection, and the limit block 108 is inserted into the limit groove to reinforce and lock the protective cover 101. At this time, the prompt cover 106 repels birds through its unique warning color and reflective material to provide an anti-electric warning;

[0037] When the wind blows, the wind entering from the cover 102 can be discharged upward through the air vents 107, or discharged downward from the bottom of the protective cover body 101. The wind entering from the bottom of the protective cover body 101 can be discharged upward through the air vents 107, or discharged outward through the cover 102. In this way, when there is wind, the impact of the wind on the protective cover can be reduced. When the wind is discharged upward, the wind blows the prompt cover 106 upward. The changes in wind strength cause the prompt cover 106 to swing up and down intermittently, further driving away birds to provide anti-electric warning. When the wind stops, the prompt cover 106 rotates downward to reset.

[0038] In addition, when the protective cover body 101 is closed, the two sheaths 102 are closed to surround the wires. The sheaths 102 drive the first locking block 301 and the second locking block 302 thereon to approach each other to achieve the locking of the two sheaths 102, preventing the sheaths 102 from opening at will, such as being stretched open by the wires, thereby preventing the protective cover body 101 from being blown away by the wind. At the same time, the two lock buckles 201 are inserted into the umbrella skirt structure of the insulator to strengthen the connection between the insulator and the protective cover, further preventing the protective cover from being blown away by the wind.

[0039] Example 2: Based on Example 1, an installation tool for an insulator safety shield, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 11 As shown, it includes a fixed rod 401, the right end of the fixed rod 401 is rotatably connected to the connecting sleeve 402, the front left end of the fixed rod 401 is fixedly connected to a fixed cylinder 403, the fixed cylinder 403 is rotatably connected to the expansion plate 404, the right part of the expansion plate 404 is fixedly connected to a spring piece 405, the front left and right parts of the expansion plate 404 are respectively provided with fixed and rotating limit clamps 406, the limit clamp 406 on the right part is fixedly connected to the spring piece 405, the right part of the expansion plate 404 is slidably connected to the first piston rod 407, the right side of the limit clamp 406 on the right part is provided with a slot, the limit clamp 406 on the right part is engaged with the first piston rod 407 through the slot, and a spring 408 is fixed between the expansion plate 404 and the first piston rod 407.

[0040] like Figure 7-11 As shown, it also includes a connecting tube 501, which is connected to the fixed tube 403, and an air cavity is opened on the side of the expansion plate 404 close to the connecting tube 501. One side of the air cavity is connected to the connecting tube 501, and the other side of the air cavity is slidably connected to the first piston rod 407. The second piston rod 502 is slidably connected in the up and down directions in the fixed tube 403, and a guide frame 503 is rotatably connected to the fixed tube 403. The guide frame 503 is threadedly connected to the second piston rod 502, and a pull rope 504 is fixed to the guide frame 503. A wire block 505 is fixed to the fixed rod 401, and a wire pulley 506 is rotatably connected to the connecting sleeve 402. The wire block 505 and the wire pulley 506 are both used to guide the pull rope 504.

[0041] Since the existing installation tool is difficult to remove the protective cover body 1 alone after it is installed on the insulator, when it is necessary to loosen the sheath 102 by the limit clamp 406, the pull rope 504 is pulled downward, and the pull rope 504 pulls the guide frame 503 to rotate, thereby driving the second piston rod 502 to slide downward relative to the fixed cylinder 403, so that the gas in the air cavity of the expansion plate 404 is sucked into the fixed cylinder 403 through the connecting pipe 501, and the negative pressure in the air cavity of the expansion plate 404 causes the first piston rod 407 to slide to one side of the compression spring 408 until the second piston rod 407 is released. A piston rod 407 no longer jams the limit clamp 406. At this time, the spring piece 405 in the bent deformation state is reset, thereby pushing the limit clamp 406 to rotate to the side away from the spring piece 405, so that the limit clamp 406 no longer jams the sheath 102. In this way, on the basis of adapting to the flexible rotation of the expansion plate 404, the limit clamp 406 can be released from the sheath 102 by simply pulling the pull rope 504 downward, so that after the installation is completed, the installation tool can be easily and quickly detached from the protective cover, and in this process, the expansion plate 404 will not be pulled to rotate.

[0042] When it is necessary to make the limiting clip 406 clamp the sheath 102, first open the protective cover body 101, and then rotate the limiting clip 406 toward the side close to the spring piece 405 so that the limiting clip 406 clamps the sheath 102, and the spring piece 405 bends into an L shape. When the limiting clip 406 rotates until the slot is aligned with the first piston rod 407, the spring 408 resets so that the first piston rod 407 clamps the limiting clip 406 again.

[0043] The above is a detailed introduction to the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the idea of ​​the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
