Description

Technical Field

[0001] The 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 the top priority. 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 some cases. In the design of safe grounding of the high-voltage platform of the neutral beam auxiliary power supply, manual grounding rods were used to ground the high-voltage platform and then perform related operations. However, with the increase of acceleration voltage (from tens of kV to hundreds of kV), manual grounding rods are too long and heavy to operate and are inconvenient. At the same time, they may 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 protection grounding ladder came into being, aiming to improve the safety of high-voltage equipment operation through a more complete and intelligent protection mechanism. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a high-voltage platform interlocking protective 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 object, the present invention provides a high-voltage platform interlocking protection grounding ladder, which is composed of 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 moving direction of the ground ladder unit;

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

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

[0009] The guide rail fixing platform unit is used to fix the guide rail and bear the overall 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 controller unit and the electrical secondary circuit of the controllable motor wheel unit.

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

[0013] 1. Improve operational safety

[0014] Intelligent interlocking protection: The grounding ladder integrates intelligent monitoring and interlocking protection mechanisms, which can monitor the status of high-voltage equipment in real time. When the high-voltage equipment is energized, the grounding ladder will automatically lock or prohibit entry to prevent operators from mistakenly entering the dangerous area, thereby significantly reducing the risk of electric shock and other safety accidents.

[0015] Reliable grounding: High-performance grounding materials and designs are used to 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 operation of the grounding ladder has become easier and faster. Operators can complete the grounding operation quickly and easily without the time-consuming and laborious traditional manual grounding rods. This not only saves time, but also improves work efficiency.

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

[0019] 3. Strong adaptability

[0020] Adapt 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 also be expanded and upgraded according to actual needs. For example, safety facilities such as insulating pedals and guardrails can be added to provide more comprehensive protection for operators.

[0022] 4. Reduce maintenance costs

[0023] Durability: The grounding ladder manufactured with high-quality materials and advanced technology 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 grounding ladder indirectly reduces the costs of downtime losses, equipment damage and casualties caused by accidents.

[0025] The present invention combines the safety grounding function with the convenience of the climbing work ladder, aiming to improve the safety and efficiency of workers entering and working on the high-voltage platform. When the on-site operator needs to perform a high-voltage platform operation task, the device can achieve automatic grounding operation through advanced wireless control technology, effectively shortening the operation preparation time and reducing the risk of human operation. In addition, the design of the grounding ladder also fully considers the system-level safety protection, and its operation signal can be seamlessly integrated into the existing system interlocking protection system to ensure that the operation process strictly complies with safety regulations and meets the high reliability and safety standards of the industrial level.

[0026] In summary, the high-voltage platform interlocking protective grounding ladder of the present invention has significant beneficial effects in improving operational safety, improving work efficiency, strong adaptability and reducing maintenance costs. These effects work together in the operation and maintenance process of high-voltage equipment, providing a safer, more efficient and reliable solution for the development of the power industry.
