AI Technical Summary
In situations with large waves or poor lighting conditions, existing near-shore rescue methods make it difficult to accurately deliver traditional rescue tools to the vicinity of the person in the water, increasing the risk of rescue failure.
It employs an adjustable-angle launch tube, gravity head, and capture net. The launch angle is precisely controlled by the elevation adjustment device of the launch tube and the infrared sight. The gravity head's dispersion head design allows the capture net to quickly unfold after launch, forming a fan-shaped coverage area. Combined with the kinetic energy provided by the combustion of gunpowder, it reaches the target.
It enables rapid and accurate delivery of rescue equipment in harsh environments, improving the success rate of rescues and adapting to dynamic calibration for turbulent seas and moving targets.
