Description

Technical Field

[0001] This utility model belongs to the field of live-line working application technology, and relates to an integrated shielding cover for live-line working with double crossarms. Background Technology

[0002] In daily live-line work on power distribution networks, workers typically use insulating blankets, insulating tubes, and other insulating shielding tools to take necessary insulating shielding measures for any live or grounded conductors that may be touched within the work area. Effective insulating shielding measures are essential to ensure the safety of workers during live-line work. When performing live-line splicing (removal) of lead wires near the ends of double crossarms on straight poles, the splicing points of the two phase lead wires are often very close to grounding components such as the ends of the crossarms. During the work, there is a risk that different parts of the human body may be exposed to components with different potentials if not careful. Therefore, it is necessary to take necessary insulating shielding measures. The conventional operation method is to use conductor shielding covers to insulate and shield the conductors at both ends of the insulator, and then use insulating blankets to insulate and shield the insulator and the ends of the crossarm. This method requires a large number of tools, about 3-4 insulating blankets and 6-8 blanket clamps are needed at the ends of the double crossarms. The number of times the equipment is touched during the operation is about 12 times. It requires high skills in wrapping the insulating blankets and the labor intensity is relatively high. Incomplete overlapping and shielding can also cause certain risks and injuries to the personnel who are connecting (removing) the leads.

[0003] Based on the above problems, this utility model proposes an integrated shielding cover for live-line work with double crossarms. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] like Figure 1-6 As shown. A double crossarm integrated shielding cover for live-line work includes an L-shaped shielding cover 1, a first insulating plate 2, and a second insulating plate 3. The L-shaped shielding cover 1 has a first opening 101 on one side, a second opening 102 on one side of the horizontal shielding body, and a third opening 103 on the side of the vertical shielding body. The L-shaped shielding cover 1 is hollow inside. A first opening 104 is provided on the other side of the L-shaped shielding cover 1. The first insulating plate 2 is inserted into the first opening 101, and a second opening 201 is provided on the first insulating plate 2. The first opening 104 and the second opening 201 are opposite each other. The second insulating plate 3 is inserted into the third opening 103. The first opening 101, the second opening 102, the third opening 103, the first opening 104, and the second opening 201 are interconnected. The horizontal shielding body of the L-shaped shielding cover 1 is a crossarm shielding cover, and its vertical shielding body is a conductor shielding cover.

[0029] From a structural design perspective, this application adopts a drawer-type modular design. Unlike insulating blankets, the shield does not require repeated adjustments or checks on its tightness during installation. Throughout the installation process, workers remain outside the isolation range of the insulating shield, eliminating the risk of contact with equipment. The assembled integrated shield can completely isolate and enclose the working surfaces in five directions (up, down, left, right, and front), effectively isolating workers from contact with components at different potentials during live-line work.

[0030] Specifically, the second insulating insert 3 is equal in length to the extended top plate 105.

[0031] like Figure 2-4As shown. In order 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. Specifically, the top of the vertical shielding body of the L-shaped shielding cover 1 is provided with an extended top plate 105, and the outer side of the first insulating plug 2 is provided with an L-shaped extension plate 202. The other side of the L-shaped shielding cover 1 opposite to the first insulating plug 2 is also provided with an L-shaped extension plate 202. The extended top plate 105, the L-shaped extension plate 202 and the second insulating plug 3 are spliced ​​together to form a square pipe. The square pipe makes it easy to achieve a 15cm insulation length overlap with the wire shielding covers on both sides.

[0032] like Figure 2 As shown. Specifically, the L-shaped shield 1 has a first slot 4 inside its horizontal shielding body, and the first insulating plate 2 is inserted into the first opening 101 through the first slot 4.

[0033] Specifically, the side of the vertical shield of the L-shaped shield 1 and the bottom of the extended top plate 105 are provided with opposing second slots 5, and the second insulating plate 3 is inserted into the third opening 103 through the second slot 5.

[0034] like Figure 3-4 As shown. The first opening 104 is an L-shaped hole, and the second opening 201 is a U-shaped hole. The L-shaped and U-shaped holes facilitate the installation of wires.

[0035] like Figure 6 As shown. Specifically, each of the L-shaped shielding cover 1, the first insulating plate 2, and the second insulating plate 3 is equipped with an insulating handle 6.

[0036] like Figure 1-6 The process of using this utility model is as follows: The operator removes the first and second insulating plates of the integrated insulating shield beforehand; the operator holds the insulating handle of the L-shaped shield and moves the third opening of the L-shaped shield horizontally along the right side of the conductor to be shielded on the end of the crossarm; then the operator inserts the second insulating plate into the third opening through the second slot and installs it at a suitable position on the L-shaped shield; the operator moves the work position and inserts the first insulating plate into the first opening through the first slot and installs it at a suitable position on the L-shaped shield from the left side; after all the above devices are in place, the shields for the conductors on both sides are moved towards the crossarm to meet the insulation overlap length requirement.
