Abstract

PURPOSE: To assure the safety of life of a diver, by providing a lifting means hanging a pressure reduction chamber so that the lifting means can be swung up and down and by quickly throwing the pressure reduction chamber from a boat into the sea in case of emergency.
CONSTITUTION: To throw the pressure reduction chamber required by the diver into the sea when an emergency happens, a handle of a disconnecting mechanism 10 is operated first, thereby disconnecting the pressure reduction chamber 2 from a diving preparation chamber 3 fixed to a deck 1a. Then, a hydraulic cylinder 8 on a rest 1d is operated to move the pressure reduction chamber 2 sidewards from the diving preparation chamber 3. Thereafter, a handle for a separating member 9 is operated and the cylinder 8 is contracted to also move the separating member 9 sidewards and disconnect it from the pressure reduction chamber 2. A winch is operated to wind a hanger rope 5b upward to hang the pressure reduction chamber 2. A hydraulic cylinder 7 is operated to turn a gate-type crane 5 to the side of the sea. The hanger rope is loosened, thereby throwing the pressure reduction chamer into the sea.
