When the shielding cover 1 is opened, the wire can enter the shielding groove through the slit between the second side panel 122 located on an inner wall of the shielding groove and the first side panel 121 located on the other inner wall opposite to the shielding groove; the other side wall of the second side panel 122 may be connected to an inner wall of the shielding groove, or may not be connected to an inner wall of the shielding groove. In the present embodiment, preferably, the other side wall of the second side panel 122 is connected to an inner wall of the shielding groove. In this way, the creepage distance in the shielding groove can be increased while simplifying the structure of the shielding cover 1, thereby improving the insulation shielding effect of the shielding cover 1 and reducing the space occupancy rate of the shielding cover 1, further preventing operators and tools from accidentally contacting live parts and reducing the risk of electric shock.

[0038] In one embodiment, a first buckle 17 and a second buckle 18 are provided on two opposite outer walls of the shielding cover 1, and a third buckle 165 and a fourth buckle 166 are provided on two opposite inner walls of the shielding cover external sleeve 16. The first buckle 17 on different shielding covers 1 is cooperated and connected with the third buckle 165, and the second buckle 18 on different shielding covers 1 is cooperated and connected with the fourth buckle 166, so that different shielding covers 1 can be cooperated and connected. It should be noted that when it is necessary to connect multiple shielding covers 1 together, it is only necessary to connect the first buckle 17 of one shielding cover 1 with the third buckle 165 on the external sleeve 16 of another shielding cover, and at the same time, the second buckle 18 of the second shielding cover 1 with the fourth buckle 166 on the external sleeve 16 of the first shielding cover. According to actual needs, buckles of different shapes and sizes can be designed to meet the connection requirements between different shielding covers 1, such as rotatable buckles to facilitate fine-tuning during the connection process. In this way, multiple shielding covers 1 can be conveniently connected together to form a longer shielding structure to adapt to insulating rods of different lengths or more complex working environments. At the same time, the operating difficulty and time cost are reduced, thereby improving working efficiency.

[0039] In one embodiment, the shielding cover outer sleeve 16 is provided with a first guide piece 167 and a second guide piece 168 on one end away from the shielding cover 1, and the first guide piece 167 and the second guide piece 168 are radially extended outward. It should be noted that the first guide piece 167 and the second guide piece 168 can form a guide groove; when the shielding cover outer sleeve 16 on one shielding cover 1 is docked with another shielding cover 1, the other shielding cover 1 can be introduced into the shielding cover outer sleeve 16 through the first guide piece 167 and the second guide piece 168. In this embodiment, preferably, the first guide piece 167 is provided on an inner side wall of the installation groove, and the second guide piece 168 is provided on the other inner side wall of the installation groove; thus, when multiple shielding covers 1 need to be connected together, the shielding cover outer sleeve 16 on the shielding cover 1 can be more smoothly connected with different shielding covers 1, reducing the difficulty of operation.

[0040] Therefore, the lightweight shielding cover for the insulating rod of the present invention solves the technical problems of the insulating shielding cover 1 in the prior art, such as the inconvenient installation and operation and the high risk, and achieves beneficial effects: 1) The wire groove is arranged in the shielding groove to ensure that the wire can be well insulated and shielded, effectively preventing the operator and the tool from accidentally contacting the live part, and reducing the risk of electric shock; 2) The first clamping arm 21 and the second clamping arm 22 are used to make the shielding cover 1 easy to open and close, simplifying the installation process. At the same time, it can be connected to the insulating rod, so that the operator can install and disassemble it through the insulating rod, avoiding the risks brought by the glove method operation, and improving the work efficiency and safety; 3) By adopting a thin-wall structure, the weight of the shielding cover 1 is significantly reduced, making the operation more convenient, reducing the physical exertion of the operator, and making it easier for the operator to carry and operate, thereby improving work efficiency and safety; 4) By utilizing overlapping and The first cover plate 12 and the second cover plate 13, which are arranged at intervals, and their V-shaped plate structure, can increase the creepage distance in the shielding groove while simplifying the structure of the shielding cover 1, thereby improving the insulation shielding effect of the shielding cover 1 and reducing the space occupancy rate of the shielding cover 1, further preventing operators and tools from accidentally contacting live parts, and reducing the risk of electric shock; 5) The shielding cover external sleeve 16 is adopted, so that the shielding cover 1 can be suitable for wires of different sizes, thereby enhancing the versatility and flexibility of the shielding cover 1; 6) Buckles are used on both the shielding cover 1 and the shielding cover external sleeve 16, so that multiple shielding covers 1 can be easily connected together, which is suitable for the shielding needs of longer wires, further improving work efficiency and safety; 7) The first guide piece 167 and the second guide piece 168 are provided, so that the connection between the shielding cover external sleeve 16 on the shielding cover 1 and the different shielding covers 1 is smoother, reducing the difficulty of operation.

[0041] A second aspect of the present invention provides a method for installing a lightweight shielding cover for an insulating rod, which is described in detail below.

[0042] A method for installing a lightweight shielding cover for an insulating rod, applied to the lightweight shielding cover for an insulating rod provided in any one of the above embodiments, comprises: The first clamping arm 21 and the second clamping arm 22 are rotated, so that the first clamping arm 21 and the second clamping arm 22 drive the clamping portion to open and then drive the shielding cover 1 to open along the shielding groove; Move the first clamping arm 21 and the second clamping arm 22, and align the opened shielding cover 1 with the wire, so that the wire enters the wire groove; The first clamping arm 21 and the second clamping arm 22 are rotated, and the first clamping arm 21 and the second clamping arm 22 drive the clamping portion to close and then drive the shielding cover 1 to close along the shielding groove, so that the shielding cover 1 is sleeved on the wire.
