MARITIME DRAFT LINE OPEN SEA DIRECT DISCHARGE DEVICE BY 'OPEN SEA DISCHARGE CYLINDRICAL SCREW DEVICE'

摘要

PROBLEM TO BE SOLVED: To provide inland-installing under-sea power generation for always stably securing a large quantity of stable drainage water when discharging a large quantity of drainage water in a storage water tank in an atmospheric pressure zone to a deep sea open sea part from the inside of an under-sea ship.SOLUTION: When power-generated various drainage water successively flows in the storage water tank, securing of an always constant and stable drainage amount is required for continuously discharging the drainage water to an open sea part, and respective storage drainage water tanks of three layers are installed. A required quantity of open sea seawater is always made to flow in "a third storage drainage cushioning water tank" of the lowest part of the three layers from " a third drainage water tank water pressure adjustment second adjustment device" from " an outboard open sea connection direct discharge tank", and drainage water is successively continued to the open sea part by operation of "an open sea discharge cylindrical screw device" after adjustment operation of "a second inverse intrusion preventive drainage amount adjustment door" in "a second storage drainage water tank" from "a third drainage water tank water pressure adjustment first adjustment device".
