With the diversification and continuous development of the types and service environments of power grid facilities such as underground substations, underground cable channels and underground energy storage power stations, the emergency rescue mechanism established by previous manual methods has become less and less adaptable.
[0004] Traditional rescue facilities such as tripods and winches have the advantages of being easy to carry and assemble, but their actual usable space is small, it is inconvenient for personnel to enter and exit, and the operation is cumbersome. Once an emergency occurs, such as poisoning, suffocation, explosion, etc., the already limited and cumbersome procedures for workers entering the cable channel become obstacles during emergency evacuation and rescue, severely limiting the scale of rescue and the comprehensiveness of measures, resulting in a significant reduction in the effectiveness of emergency rescue. Therefore, it is urgent to develop a multi-layer composite operating external rescue system suitable for horizontal / vertical directions of cable channels to improve the applicability, versatility and reliability of various types of cable channel operation emergency rescue facilities.
