Description

Technical Field

[0001] This application relates to the field of power maintenance equipment technology, specifically to insulating safety tools. Background Technology

[0002] Currently, when workers perform power outage maintenance on substation structures at height, adjacent sections may be energized, or the non-working contacts of disconnectors on the same structure may be energized. In such cases, safety measures are needed to warn and isolate workers from the energized conditions. Existing safety measures involve hanging "High Voltage Danger" signs as a warning, but these cannot provide adequate physical isolation of energized parts or protection for workers. Workers on the structure may easily ignore these warnings, leading to accidental electric shocks as parts of their bodies or objects may inadvertently extend or cross over the signs to approach energized areas. While rigid insulating barriers offer better high-voltage isolation, they are currently only suitable for ground-level, indoor, and switchgear-related applications, not for use at heights. Therefore, protecting workers from electric shocks from adjacent energized structures during high-altitude work is a technical problem that needs to be solved in this field. Summary of the Invention

[0031] Application Overview

[0032] Currently, when workers perform power outage maintenance on substation structures at height, adjacent sections may be energized, or the non-working contacts of disconnectors on the same structure may be energized. In such cases, safety measures are needed to warn and isolate workers from the energized conditions. Existing safety measures involve hanging "High Voltage Danger" signs as a warning, but these cannot provide adequate physical isolation of energized parts or protection for workers. Workers on the structure may easily ignore these warnings, leading to accidental electric shocks as parts of their bodies or objects may inadvertently extend or cross over the signs to approach energized areas. While rigid insulating barriers offer better high-voltage isolation, they are currently only suitable for ground-level, indoor, and switchgear-related applications, not for use at heights. Therefore, protecting workers from electric shocks from adjacent energized structures during high-altitude work is a technical problem that needs to be solved in this field.

[0033] Therefore, this application provides an insulating safety tool.

[0034] Exemplary Insulating Safety Equipment

[0035] Figure 1 The diagram shown is a structural schematic of an insulating safety tool provided in one embodiment of this application. This application provides an insulating safety tool, in one embodiment, such as... Figure 1 As shown, the insulating safety tool includes a fall arrestor 1, a connector 2, and an insulating partition 3.

[0036] The fall arrestor 1 includes a support portion 101 and a clamping portion 102, the clamping portion 102 being mounted on a sturdy high-altitude structure of the substation. The insulating partition 3 is vertically mounted on the support portion 101 via the connector 2.

[0037] In this embodiment, the fall arrestor 1 is fixed to the sturdy high-altitude structure by the clamping part 102, so that the entire insulating partition 3 is stably installed on the sturdy high-altitude structure of the substation. Specifically, the insulating partition 3 is installed between the construction area and the adjacent energized area. When workers are working in the construction area, the vertically installed insulating partition 3 can block the workers, thereby preventing them from being shocked by the adjacent energized area.

[0038] In one embodiment, such as Figure 1 As shown, the support part 101 is a straight rod, the side of which is attached to the surface of the insulating partition 3, and the connector 2 is connected to the straight rod and the insulating partition 3 respectively.

[0039] In this embodiment, the straight rod and the insulating partition 3 are attached to each other, which allows the straight rod to support the insulating partition 3 well, so that the insulating partition 3 is sufficiently stable.

[0040] Figure 2 The diagram shown is a partial structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, combined with... Figure 1 and Figure 2 As shown, the insulating partition 3 has at least one pair of connecting holes 301. The connector 2 includes a U-shaped ring 201 and a locking rod 202. The two ends of the U-shaped ring 201 pass through the pair of connecting holes 301 from the first side of the insulating partition 3, and the U-shaped ring 201 is fitted onto the straight rod. The locking rod 202 is located on the second side of the insulating partition 3, and the locking rod 202 is connected to the two ends of the U-shaped ring 201 that extend from the connecting holes 301.

[0041] In this embodiment, the straight rod is fixed to the insulating partition 3 by the U-shaped ring 201, and then the locking rod 202 is used to fix the U-shaped ring 201 that is protruding, thereby completing the connection between the straight rod and the insulating partition 3.

[0042] Figure 3 The diagram shown is a partial structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 3 As shown, the U-shaped ring 201 has two sets of threads 2011, which extend to both ends of the U-shaped ring 201. The connector 2 also includes a nut 203, which matches the threads 2011. The locking rod 202 has two through holes 2021, which are used to pass through the two ends of the U-shaped ring 201.

[0043] In this embodiment, after aligning the two through holes 2021 of the locking rod 202 and fitting them onto the two ends of the U-shaped ring 201, the nut 203 is screwed onto the thread 2011 of the U-shaped ring 201, thereby locking the locking rod 202 and the U-shaped ring 201 together, that is, fixing the straight rod with the U-shaped ring 201.

[0044] Figure 4 The diagram shown is a partial structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 4 As shown, the clamping portion 102 includes a base 1021 and a clamp 1022. The base 1021 is connected to the support portion 101, and the clamp 1022 has a clamping area of ​​variable size. The clamp 1022 is configured to clamp the robust aerial structure in the clamping area.

[0045] In this embodiment, the fall arrestor 1 is connected and fixed to a sturdy high-altitude structure by clamping with the clamp 1022. When it is necessary to lock the fall arrestor 1 in place, the clamp 1022 is operated to reduce the clamping area; when it is necessary to remove the fall arrestor 1, the clamp 1022 is operated to expand the clamping area for removal.

[0046] Figure 5 The diagram shown is a partial structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 5 As shown, the support portion 101 is provided with a safety rope connecting portion 1011, which is used to connect a safety rope.

[0047] In this embodiment, a safety rope for ensuring the safety of workers at heights can be connected to the safety rope connection part 1011, and the other end of the safety rope can be connected to the worker's body.

[0048] Figure 6 The diagram shown is a structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 6 As shown, the insulating partition 3 is provided with a wire hole 302, which is used for the passage of the high-altitude cable 10.

[0049] In this embodiment, the overhead cable 10 can pass through the wire hole 302 to prevent the installation of the insulating partition 3 from affecting the arrangement of the overhead cable 10.

[0050] Specifically, the wire hole 302 has an upward opening, and when the insulating partition 3 is installed, the overhead cable 10 enters the wire hole 302 from above.

[0051] Figure 7 The diagram shown is a structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 7 As shown, the insulating partition 3 also includes a cable limiting plate 303, the two ends of which are respectively connected to the opposite sides of the wire hole 302.

[0052] In this embodiment, the cable limiting plate 303 and the wire hole 302 cooperate to form an enclosed area, placing the overhead cable 10 within it. This enclosed area limits the overhead cable 10, preventing it from slipping out of the wire hole 302 and also preventing it from swinging during operation and approaching high-voltage live parts, thus avoiding electric shock to workers. Furthermore, the reaction force of the overhead cable 10 on the wire hole 302 and the cable limiting plate 303 provides auxiliary support to the insulating partition 3, preventing it from shaking to some extent.

[0053] In one embodiment, there are multiple fall arresters 1, with at least two fall arresters 1 installed on different robust high-altitude structures.

[0054] In this embodiment, the stability of the insulating partition 3 can be further improved by using multiple fall arresters 1, making the insulating partition 3 less likely to collapse or shake, so as to ensure the safety of the staff.

[0055] Figure 8 The diagram shown is a structural schematic of an insulating safety tool provided in another embodiment of this application. In one embodiment, as... Figure 8 As shown, the robust high-altitude structure is a channel steel 4, which connects adjacent structures of the substation. Two channel steels 4 are arranged between adjacent structures of the substation. There are two fall arresters 1, each mounted on one of the two channel steels 4. The insulating partition 3 is mounted on the two fall arresters 1 via the connector 2.

[0056] In this embodiment, the two fall arresters 1 are installed on two channel steels 4, which can effectively and stably support the insulating partition 3.
