[0021] Beneficial effects of the utility model:

[0022] This ship's water system includes a domestic fresh water tank, a technical fresh water tank, a desalination unit, and a distilled water tank. The domestic fresh water tank is pre-stored with fresh water and connected to the first pressure tank to deliver fresh water to the living area water supply system and the engine room area water supply system. The technical fresh water tank is pre-stored with fresh water and connected to the second pressure tank to deliver fresh water to the cargo area water supply system and the equipment water supply system. The desalination unit collects seawater and desalinates it into fresh water. The desalination unit is connected to the distilled water tank, and the fresh water produced by the desalination unit is stored in the distilled water tank. The distilled water tank can be isolated from or connected to the second pressure tank.

[0023] Before going to sea, the living fresh water tank and the technical fresh water tank are pre-filled with fresh water for use during navigation. This fresh water comes from the port, does not contain radioactive substances, and can be used with confidence; the living fresh water tank is connected to the first pressure tank to transport fresh water to the living area water supply system and the engine room area water supply system to meet the living water needs of the crew in the living area and the engine room area, and at the same time meet the water needs of washing the upper deck; the technical fresh water tank is connected to the second pressure tank to transport fresh water to the cargo hold area water supply system and the equipment water supply system to meet the water needs of the engine room equipment and the deck equipment, and at the same time meet the water needs of washing the deck in the cargo hold area; the distilled water tank is used to store the fresh water produced by the desalination device.

[0031] Ocean-going vessels are typically equipped with water systems that desalinate seawater into fresh water to meet the daily needs of the crew and the operation of the ship's equipment. Existing water systems include freshwater tanks and freshwater pressure tanks. The freshwater tanks contain a freshwater generator to desalinate seawater into fresh water. The freshwater tanks supply water to the freshwater pressure tanks, which in turn supply water to various parts of the ship that require water. However, the discharge of contaminated water from the Fukushima nuclear power plant in Japan has polluted the ocean. Existing water systems can only remove salt from seawater, resulting in the freshwater supplied by the freshwater pressure tanks containing radioactive substances. Crew members who come into direct or indirect contact with this water may be exposed to the radioactive substances present in the water and may be affected by its health.

[0032] To solve the above problems, Figure 1As shown, this embodiment provides a marine water system, which includes a domestic fresh water tank 1, a technical fresh water tank 3, a desalination device 5, and a distilled water tank 6. Fresh water is pre-stored in the domestic fresh water tank 1 and is connected to the first pressure tank 2 to deliver fresh water to the living area water supply system 71 and the cabin area water supply system 72. Fresh water is pre-stored in the technical fresh water tank 3 and is connected to the second pressure tank 4 to deliver fresh water to the cargo area water supply system 73 and the equipment water supply system 74. The desalination device 5 can collect seawater and desalinate it into fresh water. The desalination device 5 is connected to the distilled water tank 6, and the fresh water produced by the desalination device 5 is stored in the distilled water tank 6. The distilled water tank 6 can be isolated from or connected to the second pressure tank 4.

[0033] Before going to sea, the living fresh water tank 1 and the technical fresh water tank 3 are pre-filled with fresh water for use during navigation. This fresh water comes from the port, does not contain radioactive substances, and can be used with confidence; the living fresh water tank 1 is connected to the first pressure tank 2 to transport fresh water to the living area water supply system 71 and the engine room area water supply system 72 to meet the living water needs of the crew in the living area and the engine room area, and at the same time meet the water needs of washing the upper deck; the technical fresh water tank 3 is connected to the second pressure tank 4 to transport fresh water to the cargo hold area water supply system 73 and the equipment water supply system 74 to meet the water needs of the engine room equipment and the deck equipment, and at the same time meet the water needs of washing the cargo hold area deck; the distilled water tank 6 is used to store the fresh water produced by the desalination device 5. This fresh water is nuclear fresh water. Under normal circumstances, the distilled water tank 6 is isolated from the second pressure tank 4. When the fresh water in the technical fresh water tank 3 cannot be supplied, the distilled water tank 6 is connected to the second pressure tank 4, and the nuclear fresh water in the distilled water tank 6 is used to meet the water needs of the engine room equipment, the deck equipment, and the cargo hold area deck. Because the crew's range of movement in the cargo hold area is limited, and the nuclear-containing fresh water in the equipment has little impact on the outside world, the appropriate use of nuclear-containing fresh water will not cause serious harm to the crew's health. By pre-storing fresh water that does not contain radioactive substances, the crew's basic living water needs and the ship's basic technical water needs are guaranteed during the voyage. In the event of fresh water depletion, the nuclear-containing fresh water produced by the desalination device 5 can be used to provide emergency water supply to the technical fresh water tank 3, ensuring the normal operation of the ship's equipment while preventing contamination of the domestic fresh water tank 1 and ensuring that the areas where the crew frequently moves are not exposed to radioactive substances.

[0034] Specifically, a connecting pipe is provided between the domestic fresh water tank 1 and the technical fresh water tank 3, and a normally closed valve is installed on the connecting pipe. Under normal circumstances, the normally closed valve cuts off the connecting pipe, allowing domestic water and technical water to be supplied by two independent fresh water tanks. In the event of an emergency that endangers the safety of the ship, the normally closed valve can be opened to allow water to flow between the domestic fresh water tank 1 and the technical fresh water tank 3, preventing the water level in the domestic fresh water tank 1 from drying up and endangering the basic life of the crew.

[0035] Specifically, if Figure 1 As shown, an ultraviolet sterilizer 81 is installed between the first pressure tank 2 and the living area water supply system 71. The ultraviolet sterilizer 81 is used to disinfect the fresh water delivered by the living fresh water tank 1. The ultraviolet sterilizer 81 kills microorganisms in the fresh water, ensuring the safety of the fresh water supplied to the living area and providing safe and reliable living water for the crew.

[0036] Specifically, if Figure 1 As shown, a softening device 82 is provided between the second pressure tank 4 and the equipment water supply system 74. The softening device 82 is used to soften the fresh water delivered by the technical fresh water tank 3. The softening device 82 removes hard matter from the fresh water, making the water softer, reducing equipment wear and preventing hard matter from forming deposits inside the equipment.

[0037] Specifically, if Figure 1 As shown, the technical fresh water tank 3 is connected to the fire water supply system 75, and the technical fresh water tank 3 can transport fresh water to the fire water supply system 75. Using the fresh water in the technical fresh water tank 3 to extinguish the fire can ensure that no radioactive substances will remain on the ship during the fire extinguishing, thereby ensuring the health of the crew.

[0038] However, the fresh water in the technical fresh water tank 3 is limited. In the event of a serious fire, the fresh water capacity in the technical fresh water tank 3 may not be sufficient to extinguish the fire. To ensure fire extinguishing, the primary priority, in this embodiment, the fire water supply system 75 is also connected to the seawater main, which can transport seawater to the fire water supply system 75. In a specific implementation, fresh water from the technical fresh water tank 3 is first supplied to the fire water supply system 75 for approximately 15 minutes. If the fire is still not under control, seawater is then transported from the seawater main to the fire water supply system 75 for continued fire extinguishing, ensuring timely fire extinguishing.

[0039] Specifically, the firefighting water supply system 75 includes a residential area outlet pipe, which is connected to a technical freshwater tank 3. The technical freshwater tank 3 delivers fresh water to the residential area outlet pipe. In the event of a fire, the water used to extinguish the fire in the residential area comes entirely from the technical freshwater tank 3, preventing any residual radioactive material from remaining in the residential area and ensuring the safety of the residential area after the fire is extinguished.

[0040] Specifically, the fire water supply system 75 also includes engine room and cargo hold outlets, and a seawater main is connected to both outlets, delivering seawater to these outlets. In the event of a fire, the engine room and cargo hold areas are extinguished entirely with seawater. Since crew members rarely move around in these areas, even the presence of residual radioactive material in the engine room and cargo hold areas poses little threat to the crew.

[0041] In this embodiment, the ship's water supply system also includes a storage room for storing drinking water. This storage room allows for the storage of large quantities of drinking water on board in advance to ensure water needs during navigation. Other beverages, such as milk, can also be stored in the storage room.

[0042] This embodiment also provides a ship, including the ship water system as described above, which ensures the basic living water needs of the crew during navigation and the basic technical water needs of the ship by pre-storing fresh water that does not contain radioactive substances. In the event of depletion of fresh water, the nuclear-containing fresh water produced by the desalination device 5 can be used for emergency water supply to the technical fresh water tank 3, thereby ensuring the normal operation of the ship's equipment. At the same time, it will not cause pollution to the living fresh water tank 1, and ensure that the areas where the crew frequently move around will not be exposed to radioactive substances.

[0043] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
