Description
Technical Field
The present invention relates to ship bilge hydrofoil systems, and more particularly, to a tamper-resistant bilge hydrofoil system.
Background
The current international large environment is increasingly strict for environmental protection, the bilge water of the ship mainly comes from condensate water of discharged water, water making machines and air conditioners of all platforms of the ship, the condensate water comes from mechanical equipment and inevitably contains fuel oil and lubricating oil components, the bilge water (containing purified water discharged cabin reclaimed water) is strictly discharged from all countries at present, the punishment is high, and the bilge water condensate water is a necessary item for port inspection officers. The limit of the international convention on the discharge standard is 15ppm, and the oil content value is regarded as unqualified after exceeding 15ppm, and the water tank at the bottom of the tank is required to be returned, and the discharge of the side is forbidden.
In the monitoring process, the key step comes from the sampling pipeline, once the sampling pipeline is tampered, after the standard-reaching water is reserved in the sampling pipeline, the oil content value of the sensor is always lower than 15ppm, the condition that the shipboard water reaches the standard or not can be caused, the sensor is detected to be qualified, the substandard water is discharged to the outside of a ship, and the environmental pollution is caused.
In view of the above, there is a need for a tamper-proof sampling line design that prevents substandard water from being discharged overboard.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the anti-tamper bilge water discharge board system of the present invention has a clean water discharge pump 6 disposed at the water outlet of the bilge water tank, and the clean water discharge pump 6 is connected to the sampling water pipe and the water outlet pipe;
the sampling water pipe is connected with a flow switch 2 and an oil concentration detector 4, and the oil concentration detector 4 and the flow switch 2 are connected to the PLC 1;
the water outlet pipe is branched into an outboard water outlet pipe and a bilge water tank return pipe through a first three-way valve 3; an outboard water outlet pipe is communicated to the outboard of the ship, and a bilge water tank return pipe is communicated to a bilge water tank water inlet;
the PLC controller 1 is connected to the first three-way valve 3 and is used for controlling the direction of conduction of the first three-way valve 3.
The first three-way valve 3 is a pneumatic three-way valve.
The pneumatic three-way valve is also connected to the vent pipe.
The oil concentration detector 4 is also connected to the fresh water flushing pipeline.
The outboard water outlet pipe is provided with a flowmeter 5.
The PLC controller 1 is also connected to a flow meter 5.
The outboard water outlet pipe is also communicated with a bilge water tank return pipe through a second three-way valve.
The second three-way valve is a manual three-way valve.
When the invention is used, water discharged from the bilge water tank simultaneously enters a sampling water pipe and a water outlet pipe through the purified water discharge pump 6, the flow switch 2 on the sampling water pipe detects whether water enters the sampling water pipe or not, and transmits a detection result to the PLC controller 1; the water continuously enters the oil concentration detector 4 (the oil concentration detector 4 can be a 15ppm oil concentration detector) to carry out concentration detection, a detection result is transmitted to the PLC controller 1, only when the flow switch 2 detects that water enters the sampling water pipe and the oil concentration detected by the oil concentration detector 4 is less than or equal to a preset value (such as 7ppm), the PLC controller 1 can control the first three-way valve 3 to conduct the water outlet pipe to the outboard water outlet pipe, at the moment, the water enters the outboard water outlet pipe and is discharged to the outboard, and in the outboard discharging process, the flow meter 5 on the outboard water outlet pipe can detect the flow of the discharged water and store the information to the PLC controller 1; if the flow switch 2 detects that no water enters the sampling water pipe, the sampling water pipe is blocked or does not flow due to human factors, at the moment, the PLC 1 sends an alarm signal to the AMS, and controls the first three-way valve 3 to conduct the water outlet pipe to the return pipe of the bilge water tank. Similarly, if the oil concentration detected by the oil concentration detector 4 is greater than a preset value, the PLC controller 1 still controls the first three-way valve 3 to conduct the water outlet pipe to the bilge water tank return pipe, and the water is finally returned to the bilge water tank for circular filtration until the requirement is met.
If water is discharged to the outboard side after entering the outboard water outlet pipe, for some special reasons (such as detection equipment failure) we want to guide it back to the bilge water tank, only the second three-way valve needs to be controlled to conduct with the bilge water tank return pipe. If the oil concentration detector 4 needs to be cleaned, fresh water can be injected into the oil concentration detector 4, and the oil concentration detector 4 needs to be disassembled and cleaned in the cleaning process, and needs to be manually operated. The fresh water can be supplied by turning on a third three-way valve connected to the oil concentration detector 4.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
