Description

Technical Field

[0001] This utility model belongs to the field of multi-purpose ship technology, and more specifically, it relates to a multi-purpose ship fuel supply system. Background Technology

[0002] Currently, the power systems of multipurpose vessels are limited by the size of the engine room, which restricts the selection of main engine power and thus limits the vessel's design speed, making it difficult to exceed 100 knots. Therefore, existing technologies are insufficient to meet the power requirements of ships.

[0003] Existing technology includes a designation titled "Multipurpose Vessel" with publication number CN120397150A. This technology relates to the field of marine technology, and more particularly to a multipurpose vessel. The multipurpose vessel includes a hull with an open deck; a crane mounted on the open deck and located on one side of the hull; a funnel fixedly mounted on the open deck and located on the side of the hull where the crane is mounted; a living quarters fixedly mounted on the open deck and located at the bow of the hull; a bridge located on top of the living quarters; and a bridge assembly including a fixed section and a retraction section. The end of the fixed section away from the retraction section is fixedly connected to the side wall of the bridge, and the retraction section can be deployed or retracted relative to the fixed section. This invention can reduce the limitations of the bridge structure, thereby improving cargo loading efficiency and making full use of the open deck area. However, this technology does not address the technical problems and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-purpose ship fuel supply system that is simple in structure, can realize dual fuel supply and switching of the engine, ensures continuous navigation and transportation of the ship, and meets the green goals of energy conservation and emission reduction, in order to overcome the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a multi-purpose marine fuel supply system. The ship's cargo hold is equipped with a generator and a hydrogen-diesel dual-fuel engine. The generator is connected to the hydrogen-diesel dual-fuel engine. The feed pipeline of the hydrogen-diesel dual-fuel engine is equipped with a switching valve. The first feed pipeline of the switching valve is connected to the diesel tank. The ship's cargo hold is equipped with an electrolyzer for water electrolysis to produce hydrogen. The electrolyzer for water electrolysis to produce hydrogen includes a hydrogen storage tank. The second feed pipeline of the switching valve is connected to the hydrogen storage tank.

[0006] Photovoltaic panel structures are installed on the left and right sides of the ship's deck, and the photovoltaic panel structures are connected to the water electrolysis hydrogen production components of the electrolyzer.

[0007] The electrolyzer for producing hydrogen by electrolyzing water also includes an electrolyte tank electrode, which is located inside the ship's cargo hold.

[0008] The ship's cargo hold has multiple electrolyzers for water electrolysis and hydrogen production arranged at intervals from bow to stern at the lowest level.

[0009] Each frame of the photovoltaic panel structure is fitted with a photovoltaic panel component 9.

[0010] The photovoltaic panel structure extends from near the stern to near the bow.

[0011] The photovoltaic panel structure is configured to supply electrical energy to the water electrolysis hydrogen production component of the electrolyzer, and the water electrolysis hydrogen production component of the electrolyzer is configured to produce hydrogen gas.

[0012] The switching valve is a three-way electromagnetic valve.

[0013] The ship's cargo hold includes a compartment and a hatch cover. The hatch cover is located at the opening in the upper part of the compartment. The compartment is also equipped with a layered partition. The bottom of the compartment and the layered partition are respectively configured to accommodate a generator, a hydrogen-diesel dual-fuel engine, and an electrolyzer for water electrolysis to produce hydrogen.

[0014] The working principle and beneficial effects of this utility model are as follows: The multi-purpose marine fuel supply system described in this utility model is structurally designed with a generator and a hydrogen-diesel dual-fuel engine. However, the generator and engine are no longer located in the engine room but rather in the cargo hold, thus overcoming space limitations and allowing for the installation of the required number of generators and engines. The engine is a hydrogen-diesel dual-fuel engine, capable of using either hydrogen or diesel fuel. A switching valve is installed in the feed line of the hydrogen-diesel dual-fuel engine. The first feed line of the switching valve connects to the diesel tank, and the second feed line connects to the hydrogen storage tank. By switching the valve, either the first or second feed line can supply diesel fuel to the engine. This eliminates the need for large-scale diesel fuel storage and ensures efficient generator operation. An electrolyzer for water electrolysis is installed in the cargo hold. This electrolyzer produces hydrogen, which is stored in the hydrogen storage tank for use in the engine. The structure of this invention integrates an electrolyzer for water electrolysis to produce hydrogen, while the engine supplies diesel fuel. This allows the engine to supply hydrogen as fuel, overcoming the limitations of solely supplying diesel. This overcomes the technical bottleneck of traditional generators, which require continuous refueling and water replenishment due to insufficient range. The ship can continuously produce hydrogen 24 hours a day to power the engine, thus meeting the generator's power generation needs and ensuring a continuous power supply. Using hydrogen as fuel meets the requirements for long-distance navigation and also satisfies energy conservation and emission reduction requirements. Attached Figure Description

[0016] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 3 As shown, this utility model is a multi-purpose marine fuel supply system. The ship's cargo hold 2 is equipped with a generator 1 and a hydrogen-diesel dual-fuel engine. The generator 1 is connected to the hydrogen-diesel dual-fuel engine. A switching valve is installed in the feed pipe of the hydrogen-diesel dual-fuel engine. The first feed pipe 7 of the switching valve is connected to a diesel tank. An electrolyzer for water electrolysis to produce hydrogen is installed in the ship's cargo hold 2. The electrolyzer for water electrolysis to produce hydrogen includes a hydrogen storage tank. The second feed pipe 8 of the switching valve is connected to the hydrogen storage tank. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structural configuration, the generator 1 and the hydrogen-diesel dual-fuel engine are no longer located in the engine room but in the ship's cargo hold, thus avoiding the space limitations of the engine room and allowing for the installation of the required number of generators 1 and hydrogen-diesel dual-fuel engines as needed. The engine is a hydrogen-diesel dual-fuel engine, which can use either hydrogen or diesel fuel. A switching valve is installed in the feed line of the hydrogen-diesel dual-fuel engine. The first feed line 7 of the switching valve is connected to the diesel tank, and the second feed line 8 of the switching valve is connected to the hydrogen storage tank. By switching the valve, the first feed line 7 can supply diesel fuel to the engine, or the second feed line 8 can supply diesel fuel to the engine. This eliminates the drawback of the generator relying solely on diesel fuel and requiring large-scale diesel storage. An electrolyzer for water electrolysis to produce hydrogen is installed in the ship's cargo hold 2. The electrolyzer produces hydrogen, which is stored in a hydrogen storage tank for use in the engine. In this invention, the engine can supply diesel fuel while also being equipped with an electrolyzer for water electrolysis to produce hydrogen fuel, thus overcoming the shortcomings of solely supplying diesel fuel. In this way, ships can overcome the technical bottleneck of traditional generators having insufficient range and requiring continuous refueling and water replenishment. Ships can continuously produce hydrogen 24 hours a day using an electrolyzer to electrolyze water and supply it to the engine, thus meeting the generator's power generation needs and ensuring a continuous power supply. Using hydrogen as fuel can meet the needs of long-distance voyages and also meets energy conservation and emission reduction requirements. The multi-purpose marine fuel supply system described in this invention has a simple structure, can achieve dual fuel supply and switching for the engine, ensures continuous navigation and transportation, and meets the green goals of energy conservation and emission reduction.

[0017] Photovoltaic panel structures 4 are installed on the left and right sides of the ship's deck 3, respectively. These photovoltaic panel structures 4 are connected to the electrolyzer for water electrolysis and hydrogen production. In this structure, the photovoltaic panel structures can generate electricity and supply power to the electrolyzer for water electrolysis and hydrogen production via uninterruptible battery energy storage. This allows the electrolyzer to electrolyze water, decomposing hydrogen ions and cations. The resulting hydrogen is then transported to the hydrogen production unit via an electrolyte transfer pump, and finally pumped to a hydrogen storage tank via a compressor hydrogen pump. The supply of hydrogen is then controlled by switching valves to meet the generator's starting requirements.

[0018] The electrolyzer for hydrogen production via water electrolysis also includes an electrolyte tank electrode 6, which is located within the ship's cargo hold 2. In this structure, the electrolyte tank electrode 6 is positioned within the cargo hold 2, providing dedicated space for the engine, generator, and the electrolyzer for hydrogen production via water electrolysis, without occupying space in the engine room, which can then house other components.

[0019] The ship's cargo hold 2 has multiple electrolyzers for water electrolysis and hydrogen production arranged at intervals from bow to stern on its lowest level. The electrolyzers and water electrolysis hydrogen production components described above are mature technologies in the prior art. This invention does not innovate but directly applies them to meet the needs of ships.

[0020] Each frame of the structural frame 5 of the photovoltaic panel structure 4 is fitted with a photovoltaic panel 9. The photovoltaic panel structure 4 extends from near the stern to near the bow. The structural frame is fixed to the ship's deck to reliably secure the photovoltaic panel 9. Multiple photovoltaic panel 9s are installed, and the photovoltaic panel structure 4 serves both as a fence and as a power generator.

[0021] The photovoltaic panel structure is configured to supply electrical energy to the water electrolysis hydrogen production component of the electrolyzer, and the water electrolysis hydrogen production component of the electrolyzer is configured to produce hydrogen gas.

[0022] The switching valve is a three-way solenoid valve. With this structure, the switching valve simultaneously connects to the engine inlet, the first feed line 7, and the second feed line 8, allowing for flexible switching and ensuring that only one of the first feed line 7 or the second feed line 8 is connected at a time. In other words, only one type of fuel can be supplied to the engine at any given time.

[0023] The ship's cargo hold 2 includes a compartment 10 and a hatch cover 11. The hatch cover 11 is located at the opening in the upper part of the compartment 10. A partition 12 is also installed inside the compartment 10. The bottom of the compartment 10 and the partition 12 are respectively configured to accommodate a generator 1, a hydrogen-diesel dual-fuel engine, and an electrolyzer for water electrolysis to produce hydrogen. The hatch cover 11 is installed after the generator 1, the hydrogen-diesel dual-fuel engine, and the electrolyzer for water electrolysis to produce hydrogen are in place.

[0024] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
