AI Technical Summary
Existing underwater inspection robot emergency surfacing technologies suffer from slow response speed, insufficient reliability, and low success rate in complex underwater environments. Traditional solutions also suffer from problems such as complex structure, high cost, and non-reusability, making it difficult to meet the needs of use in complex underwater environments.
An underwater inspection robot with self-rescue capability was designed. It adopts an emergency compartment and an inflation component. A trigger device controls the inflation of the air bladder with air bullets to provide additional buoyancy and enable the robot to float. The air bullets are detachable and reusable. The underwater weight of the robot is reduced by a counterweight float box, thus achieving miniaturization of the device.
It enables rapid ascent after external power is disconnected, has a fast response and does not rely on external power. The gas bomb is detachable and reusable, has a simple structure, adapts to complex underwater environments, and improves the safety and economy of underwater operations.
