Abstract
Description
Technical Field
[0001] This utility model belongs to the field of live-line working application technology, and relates to an integrated shielding cover with double insulators on the top of a straight pole for live-line working. Background Technology
[0002] In daily live-line work on power distribution networks, workers typically use insulating blankets and tubing to shield any potentially accessible live or grounded conductors within the work area. Effective insulation is crucial for ensuring worker safety during live-line work. When performing live-line splicing (removal) of lead wires on the tops of double-pole straight sections, the middle phase lead wire splicing point is often very close to grounding components such as the top iron fittings on the side poles. A slight mishap during the operation can result in different electrical conductors entering different parts of the worker's body. The risky behavior of the insulator components necessitates the implementation of necessary insulation and shielding measures. The conventional method involves using conductor shielding covers to insulate and shield the conductors at both ends of the insulator, followed by using insulating blankets to insulate and shield the insulator and metal components. This method requires a large number of tools; approximately 3-4 insulating blankets and 6-8 blanket clips are needed at the top of a double pole. The operation involves approximately 12 contacts with the equipment, requiring a high level of skill in wrapping the insulating blankets and resulting in relatively high labor intensity. Inadequate overlapping and shielding can also pose a certain risk of injury to personnel connecting (removing) leads during live-line work.
[0003] Based on the above problems, this utility model proposes an integrated shielding cover with double insulators on the top of a straight pole for live-line work. Utility Model Content

Compared with existing technologies, this device, through the design of the combination of a first shielding body, a second shielding body, a top plate, a side plate, and a closing plate, eliminates the need for repeated adjustments and checks of airtightness during the installation process, unlike insulating blankets. Throughout the installation process, the operator remains outside the isolation range of the insulating shielding cover, preventing the risk of touching the equipment and effectively isolating the operator from touching components with different potentials during live-line work.

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.
[0026] like Figure 1-3 As shown. A double-insulator integrated shielding cover for live-line work on a straight pole includes a first shielding body 1, a second shielding body 2, a top plate 3, side plates 4, and a sealing plate 5; the first shielding body 1 and the second shielding body 2 are arranged opposite to each other; the top plate 3 is connected to both the first shielding body 1 and the second shielding body 2; two side plates 4 are provided, and the two side plates 4 are respectively connected to the two sides of the first shielding body 1, the second shielding body 2, and the top plate 3; each side plate 4 is provided with a slot 6; the slot 6 is U-shaped; two sealing plates 5 are provided, and the two sealing plates 5 are respectively connected to the two side plates 4; the first shielding body 1, the second shielding body 2, the top plate 3, and the side plates 4 form an integrated hollow structure.
[0027] This application adopts a bell-shaped design from a structural design perspective. Unlike insulating blankets, the shield does not require repeated adjustments or checks on its tightness during installation. Throughout the installation process, the operator remains outside the isolation range of the insulating shield, eliminating the risk of contact with the equipment. The assembled integrated shield can completely isolate and enclose the working surfaces in five directions (up, down, left, right, and front), effectively isolating the operator from contact with components at different potentials during live work.
[0028] Specifically, both the first shielding body 1 and the second shielding body 2 are configured as L-shaped structures.
[0029] Specifically, two connecting plates 7 are respectively provided at the bottom ends of the first shield 1 and the second shield 2, and the two connecting plates 7 are respectively connected to the two side plates 4.
[0030] like Figure 1-2 As shown, this design of the bottom cover is intended to provide insulation and isolation to the bottom of the top iron component of the pole.
[0031] Specifically, an extension slot plate 401 is provided on the upper outer side of each side plate 4. The extension slot plate 401 is configured as an inverted U-shaped structure. An L-shaped extension plate 501 is provided on each closed plate 5. The L-shaped extension plate 501 is connected to the extension slot plate 401. The vertical plate of the L-shaped extension plate 501 is tightly fitted to the outer side of the extension slot plate 401. The extension slot plate 401 and the L-shaped extension plate 501 cooperate to form a square pipe. The square pipe is designed to meet the technical requirement of 15cm insulation between different shielding devices. The two ends of the shielding cover are designed as square pipes with a side length of about 15cm to facilitate the overlap of the 15cm insulation length with the wire shielding covers on both sides.
[0032] like Figure 3 As shown. Furthermore, each closed plate 5 is also provided with an arc-shaped support plate, which supports the L-shaped extension plate 501.
[0033] Specifically, the sealing plate 5 is connected to the side plate 4 by bolts. One sealing insulating plate is inlaid on each side to facilitate sealing on both sides.
[0034] like Figure 1-2 As shown. Specifically, insulating handles 8 are provided on the first shelter 1, the second shelter 2, and the top plate 3. The insulating handles facilitate easy access for workers wearing insulating gloves.
[0035] like Figure 1-3 As shown. The usage process of this utility model is as follows: the operator removes the insulating sealing plates on both sides of the shielding cover in advance and maximizes the slot distance; the operator holds the insulating handles of the first shielding body and the second shielding body and places the shielding cover slot opening in the appropriate position from top to bottom along the top of the double insulator to be shielded; after the operator checks that the shielding cover is in place, the operator moves the working position and pushes the supplementary insulating sealing plates forward along the track groove from the left and right sides to complete the left and right side sealing and isolation; after all the above devices are in place, the shielding covers of the conductors on both sides are moved towards the crossarm to meet the insulation overlap length requirements.
