Insulated device null for deep-sea bottom sample collection container

摘要

PURPOSE:To enable a device to be light by creating a high-voltage air source by utilizing a water pressure of a sea bottom and then enclosing a mud sampler by forming a multiple air layer by introducing the compressed air to an air bag for insulation. CONSTITUTION:When a submarine reaches a specified sea bottom, a check valve 3 is opened due to the sea water pressure and sea water at the bottom of the sea flows into an air source tank 1. When the submarine rises to some extent after sampling a sample, a pressure of a surrounding sea water is reduced, thus enabling the check valve 3 to be closed, a high-pressure sea-water pressure of the sea bottom to be enclosed into the tank 1, and then air within an air bag 2 to be a high-pressure compressed air. The compressed air is allowed to flow to an air bag 9 for insulation through pressure-control valves 81-8n, thus enabling a mud sampler 10 to be enclosed with a multiple air layers for insulation. At this time, a setting pressure of the control valves 81-8n is set so that the air layer may be inflated from inside successively for reduction in pressure due to surfacing of the submarine, thus enabling each air layer to be uniform in thickness corresponding to a sea-water depth and an insulation effect to be improved. The tank 1, the air bag 2, etc., can be made of plastic, thus enabling the device to be light.
