APPARATUS FOR RAISING DEEP-SEAWATER ANG ADJUSTING ITS SUPPLY

PURPOSE: A deep sea water rise control device is provided to raise a large quantity of deep sea water to about the sea surface quickly without a pump. CONSTITUTION: A deep sea water rise control device(100) comprises a storage container(20), a fixed pipe(30), a lifting pipe, and a lift control unit. The storage container is installed in a marine structure(10), separate from the sea water, and receives deep sea water to the sea surface within a receiving space because the bottom of thereof is located under the sea surface. The fixed pipe is inserted and fixed to the bottom of the storage container and communicated with the receiving space. The bottom of the fixed pipe is separated from the sea bottom for drawing deep sea water in. The lifting pipe is provided on the top of the fixed pipe and raises deep sea water through the fixed pipe according to pressure difference from the sea water caused by the lifting of the lifting pipe. The lift control unit controls the lifting height of the lifting pipe in the fixed pipe.
