Considering the application environment and requirements of the ship, the best solution is to adopt a comprehensive power supply system combining photovoltaic and electrochemical energy storage. Therefore, a photovoltaic energy storage system for ships is proposed herein to solve the above problems.

[0032] Please refer to Figure 1 and Figure 2 , the ship of the present embodiment may include a hull 1, a separation cabin 2, a cargo area, a bow 4, a living cabin 11, and a photovoltaic energy storage system for the ship.

[0033] Specifically, a living area 10 is formed at the rear end of the hull 1 (the front end is where the bow is located), and the living cabin 11 is arranged in the living area 10. The separation cabin 2, the cargo area, and the bow 4 can all be arranged on the hull 1, and the living area 10, the separation cabin 2, the cargo area, and the bow 4 are arranged side by side in sequence along the longitudinal direction of the hull 1, so that the separation cabin 2 is located between the living area 10 and the cargo area.

[0034] In this embodiment, the cargo area is used to install the LNG tank 3. In some other embodiments, the cargo area can be used to install or place other goods, such as a cargo hold, a container hold, etc.

[0035] Therefore, in this embodiment, the separation cabin 2 is located between the living cabin 11 and the LNG tank 3, so that the separation cabin 2 can be used to isolate the living cabin 11 and the LNG tank 3, and prevent the LNG tank 3 from being affected when an accident occurs in the living cabin 11.

[0036] In addition, the bow 4 is located at the front end of the advancing direction of the hull 1, so as to be used to set up a cab, etc., which is convenient for the crew to drive.

[0037] It should be noted that the LNG tank 3 can be used to store LNG, and can also be used to store other combustible gases, such as liquefied petroleum gas, etc.

[0038] In addition, in this embodiment, an equipment cabin 101 is provided at the rear end of the hull 1, and the living area 10 is formed above the equipment cabin 101.

[0046] Specifically in this embodiment, the living cabin 11 is arranged on the top of the equipment cabin 101. At this time, the top structure of the equipment cabin 101 constitutes the deck of the living area 10. In other embodiments, when the living cabin 11 is directly arranged on the main deck of the hull 1, the deck of the living area 10 is the main deck of the hull 1.

[0047] Refer to Figure 4 , in this embodiment, the second support column 22 can be fixed on the rear side wall of the living cabin 11 and protrude backward from the rear side wall, so as to avoid connecting the bottom of the second support column 22 to the splint of the living area 10, and further make the terrace of the living area 10 have a larger space.

[0048] Specifically, the second support column 22 may include a vertical section 221 and a horizontal section 222.

The lower end of the vertical section 221 is connected to the end of the horizontal section 222, and the vertical section 221 and the horizontal section 222 are vertically arranged. At the same time, one end of the horizontal section 222 away from the vertical section 221 is welded to the rear side wall of the living cabin 11 and is located at the top of the rear side wall, thereby fixing the second support column 22 on the living cabin 11.

[0049] It should be noted that the support assembly 20 may further include a support beam 23. The support beam 23 extends along the transverse direction of the hull 1, and the support beam 23 is used to connect between the support assembly 20 and the photoelectric conversion unit 30 to facilitate the installation of the photoelectric conversion unit 30. Specifically, there are two support beams 23, and the two support beams 23 are respectively connected to the tops of the first support column 21 and the second support column 22 to connect the photoelectric conversion unit 30.

[0051] Refer to Figure 2 and Figure 3 , the ship may further include two third support columns 24. Among them, the two third support columns 24 are arranged at intervals along the transverse direction of the hull 1 and are located on both sides of the second support column 22 to support the photoelectric conversion unit 30.

Specifically, the top of the third support column 24 is also connected to the support beam 23, so that the photoelectric conversion unit 30 can be connected to the third support column 24 through the support beam 23, thereby ensuring that the photoelectric conversion unit 30 is stably connected within the living area 10.

[0052] In addition, in this embodiment, the first support column 21, the second support column 22, and the third support column 24 can all be set as square steel, so that the first support column 21, the second support column 22, and the third support column 24 can stably support the photoelectric conversion unit 30, thereby improving the anti-sea-wind ability of the support assembly 20 and the photoelectric conversion unit 30.

[0053] Figure 5 is Figure 1 a schematic exploded view of the photoelectric conversion unit of the ship.

[0054] Refer to Figure 5 , the photoelectric conversion unit 30 can be used to convert light energy into electrical energy and supply the generated electrical energy to the electrical equipment on the ship, such as the electrical equipment in the living cabin 11, thereby replacing the diesel generator for power supply.

[0055] Specifically, the photoelectric conversion unit 30 can include a mounting frame 31 and a photovoltaic panel 32. The bottom of the mounting frame 31 is connected to the support assembly 20, the photovoltaic panel 32 matches the mounting frame 31, and the mounting frame 31 fits on the bottom edge of the photovoltaic panel 32, so that the mounting frame 31 can fix the photovoltaic panel 32 and form a support for the photovoltaic panel 32 to prevent the photovoltaic panel 32 from deforming.

[0056] Refer to Figure 2 and Figure 3 , multiple photoelectric conversion units 30 can be provided, and the multiple photoelectric conversion units 30 are arranged side by side along the transverse direction of the hull 1 to shield the upper part of the terrace in the living area 10 and the energy storage busbar cabinet 40. At the same time, setting multiple photoelectric conversion units 30 can improve the overall power generation efficiency to meet the power consumption requirements of the ship.

[0057] In this embodiment, the photoelectric conversion unit 30 is inclined downward from front to back, and the front side of the photoelectric conversion unit 30 extends upward beyond the top of the living cabin 11, and the front side of the photoelectric conversion unit 30 covers at least part of the top of the living cabin 11, so that the multiple photoelectric conversion units 30 can shield the upper part of a part of the terrace in the living area 10, so that the photoelectric conversion unit 30 can shield rain and sunlight for this part of the terrace, thereby improving the function of the photoelectric conversion unit 30.

[0058] In this embodiment, the energy storage busbar cabinet 40 can be electrically connected to the photoelectric conversion unit 30 and the electrical equipment to supply the electrical energy generated by the photoelectric conversion unit 30 to the electrical equipment. The energy storage busbar cabinet 40 is installed on the deck of the living area 10 and is located below the photoelectric conversion unit 30, so that the photoelectric conversion unit 30 can shield rain for the energy storage busbar cabinet 40.

[0059] In addition, the energy storage busbar cabinet 40 can include an energy storage module and a busbar assembly. Among them, the busbar assembly is used to busbar the output current of the energy storage module and supply it to the electrical appliances on the ship. In this embodiment, the busbar assembly can be set as a busbar.

[0060] Specifically, the energy storage module can be set as a battery pack for storing electrical energy. The battery pack is used to store the excess electrical energy generated by the photoelectric conversion unit 30, and when the photoelectric conversion unit 30 cannot meet the power supply, the battery pack provides electrical energy for the electrical equipment, thereby ensuring the power consumption requirements of the living cabin 11.

[0061] The energy storage busbar cabinet 40 may further include a photovoltaic inverter integrated machine, which is used to convert the direct current generated by the energy storage module into marine alternating current for use by the electrical equipment on the ship.

Among them, the load-bearing beam 12 is installed at the bottom of the deck of the living area 10, so that the load-bearing beam 12 can enhance the structural strength of the deck of the living area 10 and the structural strength of the terrace of the living area 10, and further enable the splint of the living area 10 to stably support the support assembly 20 and ensure the stability of the installation of the photoelectric conversion unit 30. Specifically, the load-bearing beam 12 is connected to the side wall of the equipment cabin 101 and extends backward to be able to expand the deck of the living area 10 and increase the area of the terrace.
