Water-drop-shaped, unturnable-tumbler type directional gravity pendulum danger-avoiding escape cabin

Abstract

A water-drop-shaped, unturnable-frog-type, directional gravity pendulum risk-avoiding escape cabin belongs to the technical field of personal safety devices in mines or tunnels. The escape cabin comprises a shell including an arc-shaped inner wall, an inner chamber including an arc-shaped outer wall, and a rotary connection structure including a rotating shaft. The shell is rotationally connected to the rotating shaft through an end support rod, and the inner chamber is rotationally connected to the rotating shaft through an end hanging rod. The inner chamber has a rotating track relative to the shell around the rotating shaft, and an arc-shaped gap between the arc-shaped inner wall and the arc-shaped outer wall is adapted to the rotating track. The inner chamber of the escape cabin can quickly achieve static state at a new balance position under the instantaneous impact of collapsed earth and stones, ensuring that the internal personnel are always in a safe and stable posture, overcoming the problems that the internal personnel lose stable posture, safe distance and limb movement space when the existing risk-avoiding house changes posture under the impact and pushing of collapsed earth and stones.
