Marine sewage discharge control device

Abstract

The invention belongs to the field of automatic valves, and particularly relates to a marine sewage discharge control device with combination of an electronic map and an automatic valve. A microprocessor (2), a geographical analysis module (3), an information module (4), a sensor (5), a power module (6), a communication management module (7), a solenoid valve control terminal (8), a mechanical lock control terminal (9) and a real-time clock module (10) are arranged inside a marine automatic sewage discharge valve (1). The marine automatic sewage discharge valve (1) is externally connected with a ship-borne positioning system (11) and a ship-borne communication system (12), and the ship-borne communication system (12) is connected to a central data center (13). The marine sewage discharge control device can achieve the purpose that whether sewage discharge can be conducted at the position where a ship is located or not is automatically judged; dual locking of the sewage discharge valve can be conducted through the mechanical lock control terminal and the solenoid valve control terminal; the function that illegal sewage discharge of the ship is forbidden is fulfilled; and sewage discharge information can be uploaded to the central data center to achieve central control over the sewage discharge information.

Description

technical field [0001] The invention belongs to the field of automatic valves, in particular to a sewage discharge control device for ships which combines an electronic map and an automatic valve. Background technique [0002] During the voyage of the ship, various sewage will inevitably be produced. Typical examples are domestic sewage discharged from kitchens, restaurants, dishwashing rooms, laundry rooms, etc. This type of sewage can consume dissolved oxygen in water, produce red tides, endanger the survival of fish and most aquatic organisms, and produce unpleasant odors. Causes an unsightly environment and affects benthic organisms; these oily sewage from bilge water and oil tank ballast water can even reduce the resistance of aquatic organisms, reduce production, and cause cancer by being mixed into the water food chain and human aquatic food. substance. Ship sewage is a huge hazard. The United Nations Convention on the Law of the Sea promulgated by the United Nation...

AI Technical Summary

Problems solved by technology

[0003] Although there are many laws and regulations, it is difficult to monitor the ship's sewage discharge process. The current ship's sewage pipeline is just a manual rotary valve. The valve is locked by a mechanical chain lock, and some are not even locked. Even if it is locked, the key will It is in the hands of the crew, so sewage management is useless

As a result, the water pollution caused by the sewage discharge of offshore ships is very serious, and the domestic fishery and tourism have been seriously damaged.
