[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1The image shows an embodiment of the safety attachment device for a substation according to the present invention.

[0019] The safety anchor device for substations in this embodiment of the invention includes: a fixed support assembly 1, which is configured as multiple sets. Each set of fixed support assemblies 1 includes: a clamp 11 that can be clamped onto the equipment frame within the substation and a support seat 12 connected to the clamp 11; a stainless steel slide rail 2 connected between the two support seats 12 of the two sets of fixed support assemblies; a sliding cable 3 fitted onto the stainless steel slide rail 2; and a safety rope 4 connected to the sliding cable 3. The stainless steel slide rail 2 installed between the multiple sets of fixed support assemblies 1 is laid in a grid structure through connectors and / or corner brackets 5. Workers are connected to the stainless steel slide rail 2 through the safety rope 4 and the sliding cable 3. Workers move between different work points along the grid structure of the stainless steel slide rail 2 for safety protection.

[0020] In practice, multiple sets of fixed support assemblies 1 are installed on the top of the equipment area or the top of the maintenance passage in the substation. The equipment structure within the substation includes: pipe busbar fixing frames, firewall eaves, or equipment area fence posts.

[0021] The fixed support assembly 1 includes: a clamp 11 that can be clamped onto the equipment frame within the substation and a support base 12 connected to the clamp 11. The clamp 11 and the support base 12 are respectively made of high-strength aluminum alloy or galvanized steel. The fixed support assembly 1 is arranged in a stable triangular or portal frame support structure, and is quickly clamped onto the equipment frame within the substation via the clamp 11, including: a pipe busbar fixing frame, a firewall eaves, or an equipment area fence post.

[0022] Preferably, the height and angle of the fixed support assembly 1 can be adjusted within a certain range to adapt to different installation interfaces on site. In practice, the height of the clamp 11 and / or the angle of the support base 12 relative to the clamp 11 are set to be adjustable.

[0023] Furthermore, the stainless steel slide rail 2 provides a smooth, low-resistance movement path for the cable 3. The surface of the stainless steel slide rail 2 is polished, corrosion-resistant, and adaptable to the complex environment of outdoor substations. The stainless steel slide rail 2 is mounted on the fixed support assembly 1. The cross-section of the stainless steel slide rail 2 is I-shaped, C-shaped, or closed ring-shaped.

[0024] Preferably, the stainless steel slide rail 2 is made of a material with certain tensile strength, bending strength and corrosion resistance, such as high-strength 304 or 316 stainless steel.

[0025] Preferably, the length of the stainless steel slide rail 2 can be customized by span or modular splicing according to the conditions of the working area.

[0026] Preferably, the stainless steel slide rails 2 installed between multiple sets of fixed support assemblies 1 can be laid in a grid structure using connectors and / or corner brackets 5, wherein the connectors and / or corner brackets 5 are made of high-strength alloy steel or forgings. The purpose of this arrangement is to achieve full coverage of complex and narrow equipment areas (such as multiple switch cabinets, transformer bushings, busbar trays, etc.) and eliminate blind spots in protection.

[0027] Furthermore, the zipline 3 is fitted onto the stainless steel slide rail 2. In this embodiment, the zipline 3 includes at least a roller assembly for sliding along the stainless steel slide rail and an attachment point for hooking a safety rope; the zipline 3 is embedded in the stainless steel slide rail via the roller assembly, and the safety rope is attached to the attachment point via a hook. The roller assembly consists of multiple high-performance engineering plastic or bearing-bearing metal rollers, embedded in the slide rail to achieve smooth movement. The attachment point is a stainless steel D-ring or a stainless steel swivel buckle.

[0028] During implementation, a high-strength stainless steel D-ring or swivel can be extended from the bottom of the zipline 3 as the final attachment point for the safety rope 4.

[0029] Preferably, the minimum breaking strength (MBF) of the stainless steel slide rail 2, slide cable 3 and connector 5 is designed to be above 22kN (about 2200 kg), and the working load of a single hanging point is usually clearly marked as above 140kg, which is sufficient to support a fully equipped operator and the tools and materials he carries.

[0030] In the specific implementation of the safety anchor device for substations in this embodiment of the invention, the operator only needs to attach the hook of their safety rope 4 to the anchor point on the sliding cable 3. The operator is connected to the stainless steel slide rail 2 via the sliding cable 3. After completing a task at one work point, the operator does not need to untie the safety rope 4 and find a new anchor point; they can freely and smoothly move along the stainless steel slide rail 2 to the next work point, achieving uninterrupted protection.

[0031] In other embodiments of the safety anchor device for substations in this invention, an energy-absorbing element can be installed on the safety rope 4. Thus, in the event of a fall and self-locking, the energy-absorbing element can absorb most of the impact force through controlled tearing or extension, thereby minimizing the impact load acting on the worker's body and the anchor system, further ensuring personal safety.

[0032] The safety anchor device for substations according to the present invention has the following beneficial effects: The safety anchor device for substations includes: a fixed support assembly, wherein the fixed support assembly is configured in multiple groups, and any group of fixed support assemblies includes: a clamp that can be clamped onto the equipment frame within the substation and a support seat connected to the clamp; a stainless steel slide rail connected between the two support seats of two groups of fixed support assemblies; a sliding cable fitted on the stainless steel slide rail; and a safety rope connected to the sliding cable, wherein: the stainless steel slide rail installed between the multiple groups of fixed support assemblies is laid in a grid structure through connectors and / or corner brackets; the operator is connected to the stainless steel slide rail through the safety rope and the sliding cable, and the operator moves between different work points along the grid structure of the stainless steel slide rail for safety protection, which can provide dynamic and continuous fall protection and improve the load-bearing capacity of the anchor device; the structure is simple and safe and reliable.
