Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The metal semicircular ring of the mounting hole 3 has a metal connecting portion 4 extending toward the outer diameter direction, and the hard insulating material support beam 9 is connected to the metal connecting portion 4, and the two are connected by crimping, bonding or riveting. The rubber skirt 5 is encapsulated on the outer flange of the semicircular ring of the mounting hole 3, the hard insulating material support beam 9 and the supporting mesh body to form an insulating sector surface, and the inclination angle of the insulating sector surface is 9° to 17°. The composite rubber is encapsulated outside the hard insulating material support beam 9 to form an upper surface ridge 6. The lower surface of the rubber skirt 5 is also provided with radial and circumferential lower surface ridges 11. The two semicircles are composited, the rubber skirt 5 is greater than 180°, and when assembled, the connecting pieces 7 are crossed with each other and locked with the buckle 8.

[0023] In the utility model, the specific function of the device is to butt the two semicircular composite rubber skirts 5 projected on the left and right to form a complete circular umbrella skirt surface, ensure that the mounting hole 3 of the circular umbrella skirt is locked on the power hardware or insulator, and when installing, butt the metal materials of the two semicircular rings in the mounting hole 3 and fasten them with the fastening bolts 1, and adjust the inner diameter D of the mounting hole 3 by setting the center pad 2 as needed to adapt to power equipment of different sizes.

[0024] A plurality of radial hard insulating material support beams 9 are arranged inside the rubber skirt 5. The support beams are wrapped in the rubber skirt 5, providing necessary structural support and rigidity, ensuring that the umbrella skirt can stably cover and protect the power equipment after installation. The outer wall of the rubber skirt 5 is woven with annular warp threads 10 connected to the hard insulating material support beams 9, further enhancing the rigidity and support performance of the umbrella skirt and preventing the umbrella skirt from deformation during use.
