Description

Technical Field

[0001] This utility model relates to the field of insulating protective equipment for power construction, specifically an insulator shielding cover. Background Art

[0002] Currently, in power construction, using insulator shields to cover the outside of insulators effectively prevents workers from coming into contact with them during construction, avoiding safety accidents and electric shock risks caused by accidental contact. Construction sites often contain various mechanical equipment and tools; insulator shields effectively prevent accidental damage to the insulators, ensuring their integrity. Traditional insulator shields use a one-piece molded structure, and their dimensions cannot be changed. Custom sizes are required to achieve complete insulator coverage, which is costly. However, if a small portion of the insulator is exposed, it poses a significant safety hazard. Therefore, complete insulator coverage is still necessary. Thus, existing insulator shields with fixed dimensions require structural improvements. Therefore, we propose an insulator shield design. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1, as Figure 1-3As shown, this utility model provides a technical solution: an insulator shielding cover, including a shielding cover 1 and two adjustable barriers 2 of the same size. The two adjustable barriers 2 are distributed on the front and rear sides inside the shielding cover 1. The surface of the shielding cover 1 is provided with a fastening mechanism for fixing the adjustable barriers 2. The surface of the adjustable barriers 2 is provided with a sliding groove 4 for fitting into the fastening mechanism. The inner wall of the sliding groove 4 is provided with a stop bar 5. The fastening mechanism includes a bolt 6, a nut 7 and a pressure ring 9. The adjustable barriers 2 are located between the shielding cover 1 and the pressure ring 9, and the nut 7 is located outside the shielding cover 1.

[0020] In one specific embodiment of this utility model, the shielding cover 1 is a traditional insulator shielding cover, suitable for pin-type insulator shielding, made of high-density polyethylene material, with an insulation class not lower than CLASS3. Sleeves are provided at both ends of the shielding cover 1 for splicing with the conductor shielding cover. Openings are provided on both sides of the shielding cover 1, with pressure strips at the openings. The adjustable enclosure 2 is made of the same material as the shielding cover 1. The nuts 7, bolts 6, and pressure rings 9 are all made of insulating plastic. The two adjustable enclosures 2 are respectively installed on the front and rear sides of the shielding cover 1. The bolts 6 penetrate the adjustable enclosure 2 and the shielding cover 1. Screw in the nut 7. The pressure ring 9 and the shield 1 are located on both sides of the adjustable enclosure 2. When the nut 7 is tightened, the shield 1 and the adjustable enclosure 2 can be securely connected together with the pressure ring 9. When the vertical length of the shield 1 is insufficient to cover the insulator, the nut 7 can be loosened. The adjustable enclosure 2 can be adjusted to extend its length along the vertical direction of the shield 1. During the process, the T-shaped strip 3 slides along the direction of the T-shaped groove 8, the bolt 6 moves in the slide groove 4, and the two stop strips 5 are always in a tight fit. The two stop strips 5 shield the slide groove 4. After the adjustment is completed, tighten the nut 7 to securely assemble the adjustable enclosure 2 and the shield 1.

[0021] In the preferred technical solution, two T-shaped grooves 8 are opened in parallel on the inner wall surface of the shield 1, and two T-shaped strips 3 are arranged in parallel on the surface of the adjustable enclosure 2. The T-shaped strips 3 are embedded and connected with the T-shaped grooves 8, and the T-shaped strips 3 always slide inside the T-shaped grooves 8, thereby improving the stability of the adjustable enclosure 2 during adjustment.

[0022] In the preferred technical solution, two baffles 5 are provided on the inner wall of the slide groove 4. The vertical end faces of the two baffles 5 are in close contact with each other. The baffles 5 provide flexible shielding for the slide groove 4 to avoid voids that would reduce the insulation shielding performance, while also allowing the bolts 6 to move within the slide groove 4.

[0023] In the preferred technical solution, several arc-shaped grooves are provided around the circumference of the nut 7. The arc-shaped grooves help to increase the contact friction between the hand and the nut 7, making it easier to rotate the nut 7.

[0024] In the preferred technical solution, the inner cavity of the shield 1 is elliptical, and the outer shape of the adjustable enclosure 2 is an arc-shaped plate. The shape of the outer surface of the adjustable enclosure 2 matches the shape of one side of the inner wall of the shield 1, ensuring that the adjustable enclosure 2 and the shield 1 are fully attached.

[0025] In summary, this embodiment provides an adjustment mechanism that improves upon the traditional insulator shield structure by adding an adjustable enclosure 2 structure, along with a bolt and nut adjustment structure and T-shaped strips 3 and T-shaped grooves 8 auxiliary limiting structures. This allows the extension length of the adjustable enclosure 2 to be adjusted. When the vertical length of the shield 1 is insufficient to cover the insulator, the extension length of the adjustable enclosure 2 can be adjusted to fully insulate and shield the insulator.
