Technical Field

[0001] The present invention relates to the technical field of solar power generation for ships, and in particular to a ship-used photovoltaic lithium battery stacking integrated device. Background Art

[0002] International shipping and trade are a vital component of the global economy, with nearly 90% of global trade conducted by sea. As the primary means of transporting goods in today's international trade, ships consume vast quantities of fossil fuels and generate significant environmental pollution. Solar energy plays a crucial role in clean energy, and with the continuous advancement of new energy technologies, solar-powered ships have become one of the most promising green vessels.

[0003] Due to the intermittent nature of photovoltaic power generation, the low power generation of a single group, and the single power generation mode, which is limited to operating in sunny weather, it cannot be effectively integrated into the ship's power grid. However, the centralized stacking of photovoltaic lithium batteries makes it difficult to disconnect each group of lithium batteries, increasing the risk of a single fault fire leading to a collective fire and explosion, and thus lacking safety. Therefore, to address the above issues, a ship-based photovoltaic lithium battery stacking integrated device is proposed. Summary of the Invention

[0024] See also Figure 1-8 As shown, a marine photovoltaic lithium battery stacking integrated device includes a plurality of photovoltaic modules 1 distributed on a shelf 6, a lithium battery placement frame 2, and an explosion-proof hanging and detaching mechanism 4 for hanging a lithium battery pack 3. Power generation photovoltaic panels 110 are installed on both sides of the lightweight right-angle plate 120 located in each photovoltaic module 1, and the middle of the back of the lightweight right-angle plate 120 is respectively connected to the two ends of the same rope 520. The middle part of the rope 520 is wound on a single groove wheel 512 located inside a drive box 510, and a generator module 5 is installed on one end of a linkage shaft 511 located in the middle of the single groove wheel 512. The side walls around the lithium battery placement frame 2 are in sliding contact with the inner wall of the rectangular hole 910, and the top wall of the lithium battery placement frame 2 is distributed and installed with the explosion-proof hanging and detaching mechanism 4, and each of the explosion-proof hanging and detaching mechanisms 4 is hung with one of the lithium battery packs 3. Each end of the cross rod 410 located in each of the anti-explosion hanging and detaching mechanisms 4 is connected to a solution expansion glass tube 430, and each rod body of the cross rod 410 is respectively provided with a spring 420 and an L-shaped plug 440 from the inside out. One end of the solution expansion glass tube 430 is interconnected with the corresponding triangular plate 310 located at the top of the lithium battery pack 3, and one end of the L-shaped plug 440 is slidably plugged into the plug tube 320 distributed at the top of the lithium battery pack 3.

[0025] Specific structure Figure 6 As shown, a connecting column 450 is installed in the middle of the cross rod 410, and a flange 451 is installed on the top of the connecting column 450. The other end of the L-shaped plug 440 is provided with a hole structure, and the hole structure is in sliding contact with the corresponding rod body part of the cross rod 410; The flange 451 can be used to fix the top of the lithium battery placement frame 2; the hole structure opened at the other end of the L-shaped plug 440 can slide in contact with the corresponding rod part of the cross rod 410, so that the L-shaped plug 440 can move along the corresponding rod part on the cross rod 410 under the expansion and contraction of the spring 420.

[0026] Specific combination Figure 7 As shown, the middle portion of the solution expansion glass tube 430 is provided with a solution chamber 431, and a plug-in groove 432 is provided in the middle position of the other end surface of the solution expansion glass tube 430. The solution chamber 431 is used to contain liquid that expands due to heat. By providing the plug-in groove 432, the solution expansion glass tube 430 and the corresponding end of the cross rod 410 can be plugged together. At the same time, the other end of the solution expansion glass tube 430 is connected to the triangular plate 310 located at the top of the lithium battery pack 3, thereby enhancing the stability of the connection to the lithium battery pack 3 and preventing the lithium battery pack 3 from swinging.

[0027] Combine Figure 1 and Figure 2 As shown, a connecting hole 121 is provided at the corner of the lightweight right-angle plate 120, and the inside of the connecting hole 121 is rotatably connected to the corresponding connecting rod 610 located on the shelf 6 through a bearing. Wiring tubes 7 are distributed on both sides of the shelf 6. The lightweight right-angle plate 120 is used, and is rotatably connected to the connecting rod 610 through a bearing in combination with the connecting hole 121. It can be used to install a lightweight photovoltaic panel 110 at 45° for photovoltaic power generation in a windless environment, and can also use the wind to put the lightweight right-angle plate 120 in a reciprocating swing state and drive the generator module 5 to generate electricity through the rope 520 and its connecting structure.

[0028] Specific combination Figure 8As shown, the bottom ends of both sides of the shelf 6 are connected to a lateral rotation adjustment assembly 8, which includes a worm 810, a worm wheel 820 and a motor 830. The worm 810, which is meshed and connected to the worm wheel 820, is rotatably installed inside the U-shaped plate 10, and one end of the worm 810 is connected to the motor 830 located on one side of the U-shaped plate 10. The shaft located in the middle of the worm wheel 820 is respectively connected to the bearing seat 12 and the bottom end of the corresponding side of the shelf 6; The operation of the motor 830 drives the worm 810 to rotate, so that the worm wheel 820 connected to the worm 810 drives the connected shelf 6 to be in a synchronous side rotation state, thereby achieving the effect of adjusting the position angle of the shelf 6, and also facilitating folding and laying flat to avoid adverse natural environmental conditions.

[0029] The U-shaped plate 10 and the bearing seat 12 are both installed on the same hatch cover 9, and an integrated intelligent control switch module 11 is installed on the back side of the hatch cover 9. Through the integrated intelligent control switch module 11, the electrical control connection between the power generation photovoltaic panel 110, the generator module 5 and the lithium battery pack 3 can be completed.

[0030] Furthermore, the rectangular hole 910 is opened on one side of the hatch cover 9 , and a frame 920 is installed at the hole opening at the bottom of the rectangular hole 910 .

[0031] Furthermore, a reinforcement cover plate 210 is installed on the top of the lithium battery placement frame 2 , and lifting handles 220 are provided on both sides of the top of the reinforcement cover plate 210 .

[0032] Furthermore, the frame opening of the lithium battery placement frame 2 is always facing downward, and the lithium battery packs 3 located inside the lithium battery placement frame 2 are isolated from each other by a flame retardant plate structure.

[0033] The specific operation workflow is as follows: Process 1: Combination Figure 8 As shown, the motor 830 drives the worm 810 to rotate, so that the worm wheel 820 connected to the worm 810 drives the connected shelf 6 to be in a synchronous sideways rotation state, thereby achieving the effect of adjusting the position angle of the shelf 6 and facilitating the folding and laying flat to avoid adverse natural environmental conditions; Process 2: Combination Figure 1 and Figure 2 As shown, when the rack 6 is in an upright state, the photovoltaic panel 110 is exposed to the sun to generate photovoltaic power. At the same time, the sun is accompanied by wind, which causes the lightweight right-angle plate 120 to swing with the connecting rod 610 as the center point of lateral rotation. In combination with the ropes 520 connected to both sides of the back of the lightweight right-angle plate 120, the ropes 520 are also in a reciprocating pulling state, causing the single groove wheel 512 and the linkage shaft 511 connected to the ropes 520 to rotate, thereby driving the generator module 5 connected via the linkage shaft 511 to operate and generate electricity, thereby increasing the power generation capacity. Process 3: Combination Figure 5 、 Figure 6 and Figure 7 As shown, when a circuit fault occurs in one or more lithium battery packs 3 and causes a fire, the lithium battery packs 3 located inside the lithium battery placement frame 2 are isolated from each other by the flame-retardant plate structure. Therefore, a circuit fault in each lithium battery pack 3 will not cause a fire to other lithium battery packs 3 for a period of time. Therefore, under the high-temperature environment, the special liquid in the solution chamber 431 expands to its limit, causing the entire solution to expand and the glass tube 430 to burst instantly. The spring 420 extends and pushes the L-shaped plug 440 to move outward along the corresponding rod of the cross rod 410, so that the corresponding end of the L-shaped plug 440 is quickly separated from the plug tube 320 located at the top of the lithium battery pack 3. The length of the corresponding end of the L-shaped plug 440 entering the plug tube 320 is one-fourth of the length of the spring 420 after compression and expansion, which can ensure unobstructed instant separation. Process 4: After the explosion prevention hooking and detaching mechanism 4 has completely released the lithium battery pack 3, the lithium battery pack 3 that caused the fire and smoke falls from the lithium battery placement frame 2 to a predetermined fire extinguishing area, such as a river, with the frame opening of the lithium battery placement frame 2 always facing downward. This avoids triggering fire and explosion of other normal lithium battery packs 3, thereby improving the safety of stacking lithium batteries.

[0034] Compared with the existing technology, the differences are: By rupturing the liquid expansion glass tube 430 that explodes under high temperature, the connection between the anti-explosion hanging and detaching mechanism 4 and the corresponding lithium battery pack 3 is released. In addition, the frame opening of the lithium battery placement frame 2 is always facing downward, so that the lithium battery pack 3 that causes fireworks can be quickly detached and dropped. At the same time, the lithium battery packs 3 inside the lithium battery placement frame 2 are isolated from each other by the flame-retardant plate structure, thereby preventing other normal lithium battery packs 3 from catching fire or exploding, thereby improving the safety of stacking lithium batteries. The lightweight right-angle plate 120 is rotatably connected to the connecting rod 610 through a bearing in conjunction with the connecting hole 121. It can be used to install a lightweight photovoltaic panel 110 at a 45-degree angle for photovoltaic power generation in a windless environment. Furthermore, the lightweight right-angle plate 120 can be put into a reciprocating swing state by means of wind power, and the rope 520 and its connecting structure can be used to drive the generator module 5 to operate and generate electricity, thereby increasing the diversity of the overall power generation and ensuring the power generation capacity. By providing a plug-in slot 432, the solution expansion glass tube 430 can be plugged into the corresponding end of the cross rod 410, and the other end of the solution expansion glass tube 430 is connected to the triangular plate 310 located at the top of the lithium battery pack 3, thereby enhancing the stability of the connection to the lithium battery pack 3 and preventing the lithium battery pack 3 from swinging.
