This invention discloses an unmanned collaborative emergency rescue system and method for special disasters involving ships in complex waters. The system, centered on a rescue mother ship, integrates unmanned fishing and rescue boats, intelligent fire detection boats, in-cabin emergency response robots, and tethered drones, constructing an integrated "air-water-cabin" unmanned equipment cluster. Information interconnection is achieved through a three-dimensional perception network and a flexible fusion communication network. The system integrates multi-source perception data through a collaborative control terminal and intelligently schedules each piece of equipment for collaborative operations based on preset decision logic. This invention enables tiered proactive rescue of personnel on the water, precise "internal detection and external attack" fire suppression of fires inside ships, and in-cabin emergency response, while maintaining communication via drone relay in signal-blocked environments. This invention solves the technical challenges of traditional rescue methods in responding to internal ship disasters, rescuing disabled persons, and collaborative operations in complex environments, significantly improving rescue efficiency and safety.

This utility model relates to a throwable self-righting inflatable life raft, comprising a raft bottom, with an upper buoyancy tire and a lower buoyancy tire stacked on top of each other. An arc-shaped canopy spanning the life raft is mounted on the upper buoyancy tire. Each of the upper and lower buoyancy tires contains two independent air chambers, and the arc-shaped canopy is unidirectionally connected to each of the two air chambers of the upper buoyancy tire. Several air cylinders for inflating the air chambers are located on one side of the raft bottom. Its innovation lies in the four independent air chamber design. The upper and lower buoyancy tires are each divided into two independent air chambers (first to fourth air chambers) by rubber sheeting. Even if one air chamber is damaged, the remaining air chambers still maintain more than 75% buoyancy. It also features a redundant inflation system. A first one-way air inlet valve is located at each of the four corners of the arc-shaped canopy, connecting to the air chambers of the upper buoyancy tire. Combined with the air cylinders on one side of the raft bottom and a V-shaped air supply pipe, rapid inflation in 40 seconds is achieved. It also features a self-righting structure. This utility model significantly improves the life raft's anti-capsulation performance, safety redundancy, and survivability in harsh sea conditions.
