Description

Technical Field

[0001] The present invention belongs to the technical field of power equipment safety protection and high-altitude operation safety, and in particular relates to a high-voltage platform interlocking protection grounding ladder. Background Art

[0002] During the operation and maintenance of high-voltage power equipment, ensuring the personal safety of operators is always paramount. Traditional high-voltage equipment protection measures often rely on a single mechanical grounding switch or manual grounding rod, but these measures may not fully guarantee safety in certain situations. In the design of safe grounding for high-voltage platforms with neutral beam auxiliary power supplies, manual grounding rods were previously used to ground the high-voltage platform before related operations. However, with the increase in acceleration voltage (from tens of kV to hundreds of kV), manual grounding rods are too long and heavy to operate, making them inconvenient. They can also cause discharge at the moment of grounding the platform, posing a threat to personal safety. Therefore, the invention of the high-voltage platform interlocking protective grounding ladder came into being, aiming to improve the safety of high-voltage equipment operations through a more comprehensive and intelligent protection mechanism. Summary of the Invention

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a high-voltage platform interlocking protection grounding ladder, which cleverly integrates the safety grounding and the climbing ladder into one. When the on-site operators need to enter the high-voltage platform to perform operations, the grounding can be automatically performed through wireless control. At the same time, the operation signal of the grounding ladder can also be incorporated into the system interlocking protection system to meet the safety and reliability requirements.

[0004] To achieve the above-mentioned object, the present invention provides a high-voltage platform interlocking protective grounding ladder, which comprises a grounding ladder body unit, a movable guide rail unit, a grounding contact unit, a controllable motor wheel unit, a guide rail fixed platform unit, a controller unit and a secondary circuit unit;

[0005] The grounded ladder unit is used for test personnel to ascend;

[0006] The movable guide rail unit is used to fix the forward and backward movement direction of the ground ladder unit;

[0007] The grounding contact unit is used for contact between the high-voltage platform and the grounding ladder unit;

[0008] The controllable motor wheel unit is used to drive the ground ladder unit to move forward and backward;

[0009] The guide rail fixing platform unit is used to fix the guide rail and bear the entire weight of the grounded ladder unit;

[0010] The controller unit is used to control the start and stop of the grounding ladder unit;

[0011] The secondary circuit unit is used to connect the electrical secondary circuit of the controller unit and the controllable motor wheel unit.

[0012] The present invention has the following beneficial effects:

[0013] 1. Improve operational safety

[0014] Intelligent interlocking protection: This grounding ladder integrates intelligent monitoring and interlocking protection mechanisms, enabling real-time monitoring of the status of high-voltage equipment. When high-voltage equipment is energized, the ladder automatically locks or prohibits access, preventing operators from accidentally entering the danger zone, significantly reducing the risk of electric shock and other safety incidents.

[0015] Reliable grounding: High-performance grounding materials and designs ensure reliable grounding in high-voltage environments. This not only eliminates discharge, but also protects operators from electric shock and improves the safety of the working environment.

[0016] 2. Improve work efficiency

[0017] Convenient Operation: Through optimized design and structural improvements, the grounding ladder is now easier and faster to operate. Operators can quickly and easily complete grounding operations without the time-consuming and labor-intensive process of traditional manual grounding rods. This not only saves time but also improves work efficiency.

[0018] Reduce human error: The intelligent interlocking protection mechanism reduces the possibility of human error. Operators only need to follow the established steps and sequence to ensure the correctness and effectiveness of grounding operations, thus avoiding safety accidents caused by improper operation.

[0019] 3. Strong adaptability

[0020] Adaptable to various environments: This grounding ladder can adapt to high-voltage equipment of different voltage levels and working environments. Whether it is a high-voltage platform of a neutral beam auxiliary power supply or other types of high-voltage equipment, it can provide effective grounding protection.

[0021] Scalability: The grounding ladder can be expanded and upgraded based on actual needs. For example, safety features such as insulating steps and guardrails can be added to provide more comprehensive protection for operators.

[0022] 4. Reduce maintenance costs

[0023] Durability: Made of high-quality materials and advanced technology, the grounding ladder has a long service life and high durability. This reduces the frequency of replacement due to equipment damage, thereby reducing maintenance costs.

[0024] Reduce accident costs: By improving safety and reducing the occurrence of safety accidents, the ground ladder indirectly reduces costs such as downtime losses, equipment damage, and casualties caused by accidents.

[0025] This device combines a safe grounding function with the convenience of an elevated work ladder, aiming to improve the safety and efficiency of workers accessing and working on high-voltage platforms. When on-site operators need to perform tasks on the high-voltage platform, this device automatically grounds the platform using advanced wireless control technology, effectively shortening preparation time and reducing the risk of manual operation. Furthermore, the design of this grounding ladder fully considers system-level safety assurance, and its operating signals can be seamlessly integrated into the existing system interlocking protection system, ensuring that the operation process strictly adheres to safety regulations and meets industrial-grade high reliability and safety standards.

[0026] In summary, the high-voltage platform interlocking protective grounding ladder of the present invention has significant benefits in terms of improved operational safety, enhanced work efficiency, strong adaptability, and reduced maintenance costs. These benefits, combined with the operation and maintenance of high-voltage equipment, provide a safer, more efficient, and more reliable solution for the development of the power industry.

[0035] In this embodiment, the grounding ladder unit 1 is composed of a ladder body 8, a guardrail 9, and moving wheels 10.
