Description

Technical Field

[0001] The present invention relates to the technical field of marine batteries, and particularly to an anti-corrosion cell module and energy storage battery for marine vessels. Background Art

[0002] With the global emphasis on environmental protection and sustainable development, the shipbuilding industry is gradually moving towards green and electrified directions. Lithium-ion batteries have become an important choice for ship power systems due to their high energy density, long cycle life, and environmental friendliness.

[0003] Due to the high humidity, high salt mist, and strong corrosiveness of the marine environment, extremely high requirements are imposed on the sealing performance of the battery. Existing battery boxes mostly adopt external anti-corrosion coatings or simple sealing structures. However, during long-term use, salt mist may still seep into the interior of the box through gaps, corroding the cell tabs and connecting components, resulting in a decline in battery performance or even failure; traditional sealing designs often conflict with the heat dissipation requirements. For example, the outer frame of the cell module tightly wraps the internal cells, and a sealing layer for wrapping multiple cell modules layer by layer is also provided inside the battery case. This excessive sealing will hinder heat dissipation, while an open heat dissipation design is difficult to meet the anti-corrosion requirements. Summary of the Invention

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

Detailed implementation manners

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Please refer to Figures 1 to 5 , the present invention provides a technical solution: an anti-corrosion cell module for marine ships, the cell module 1 includes a main outer frame 101 and a cylindrical cell 4, and further includes a reference inner frame 2 and a plurality of movable inner frames 3. The reference inner frame 2 remains unchanged at the central position of the main outer frame 101. The plurality of movable inner frames 3 are symmetrically distributed on both sides of the reference inner frame 2 and are installed on the main outer frame 101 with limited sliding. A cylindrical cell 4 can be detachably installed in both the reference inner frame 2 and the plurality of movable inner frames 3; when the plurality of movable inner frames 3 change positions equidistantly on both sides of the reference inner frame 2, the distance between two adjacent cylindrical cells 4 can be adjusted.

[0054] Two sets of Z-axis retaining frames 7 are symmetrically arranged on the main outer frame 101. Driven by the pushing assembly, the two sets of Z-axis retaining frames 7 move linearly towards each other to push the moving inner frame 3 into close fit with the reference inner frame 2. Magnetic sheets 5 are fixedly arranged on the side walls of the Z-axis retaining frames 7, the reference inner frame 2, and the moving inner frame 3. Repulsive forces are generated between adjacent pairs of magnetic sheets 5 to push the moving inner frame 3 to quickly expand towards both sides of the reference inner frame 2. When the Z-axis retaining frames 7 are in contact with the reference inner frame 2 and the moving inner frame 3, the multiple cylindrical battery cells 4 are in a completely sealed state. When the Z-axis retaining frames 7 are separated from the reference inner frame 2 and the moving inner frame 3, the multiple cylindrical battery cells 4 are in an independent heat dissipation state.

[0055] A boss 6 is fixedly arranged on the side of the Z-axis retaining frame 7 close to the moving inner frame 3. The boss 6 is engaged at the opening of the assembly groove. The boss 6 and the side wall of the Z-axis retaining frame 7 form a stepped shape, which can better seal the side wall of the battery cell module 1.

[0056] Furthermore, through the design of the main outer frame 101, the reference inner frame 2, the multiple moving inner frames 3, and the Z-axis retaining frames 7, the outer frame of the battery cell module 1 with a modular structure is formed, which can independently assemble the multiple cylindrical battery cells 4. When the reference inner frame 2, the multiple moving inner frames 3, and the Z-axis retaining frames 7 are assembled together, it can provide a primary sealing effect on the cylindrical battery cells 4. When the multiple moving inner frames 3 are successively away from the reference inner frame 2, the multiple cylindrical battery cells 4 are separated from each other, and each cylindrical battery cell 4 can obtain a uniform ventilation and heat dissipation effect.

[0057] Such as Figures 3 - 5As shown in the figure, both the movable inner frame 3 and the reference inner frame 2 are provided with assembly grooves for accommodating cylindrical battery cells 4. Side slots 301 are provided on both the front and rear sides of the movable inner frame 3. The side slots 301 communicate with the assembly grooves. A plugging column 302 is provided in the side slots 301. A through hole 3021 is provided through the plugging column 302 in the front and rear directions. Through the cooperation of the driven assembly, the plugging column 302 can adaptively perform forward and reverse rotational movements according to the change in the position of the movable inner frame 3. The driven assembly includes a central shaft 303, a moving gear 304, and a fixed rack 305. The upper end of the central shaft 303 extends into the side slot 301 and is coaxially fixedly connected to the plugging column 302. The lower end of the central shaft 303 extends into the main outer frame 101 and is coaxially fixedly connected to the moving gear 304. A long chute matching with the moving gear 304 is provided on the upper surface of the bottom wall of the main outer frame 101. The fixed rack 305 is fixedly arranged on the side wall of the long chute. When the movable inner frame 3 fits with the reference inner frame 2, the plugging column 302 rotates clockwise, and the through hole 3021 on it is staggered from the side slot 301. At this time, the side slot 301 is plugged. When the movable inner frame 3 moves away from the reference inner frame 2, the plugging column 302 rotates clockwise, and the through hole 3021 on it coincides with the side slot 301. At this time, the side slot 301 is opened, so that ventilation can also be carried out on both the front and rear sides of the movable inner frame 3, further improving the heat dissipation effect of the cylindrical battery cells 4.

[0058] As Figure 4 and Figure 5 shown, the plugging column 302 is rotationally installed on the movable inner frame 3 through the central shaft 303 for limiting. The lower end of the plugging column 302 extends into the main outer frame 101 and is fixedly connected to a moving gear 304. A long chute for accommodating the moving gear 304 is provided on the upper surface of the bottom wall of the main outer frame 101. A fixed rack 305 meshing with the moving gear 304 is fixedly arranged in the long chute. A through hole 3021 is provided through the plugging column 302 in the front and rear directions.

[0059] When the movable inner frame 3 fits with the reference inner frame 2, the plugging column 302 on the left side of the reference inner frame 2 rotates clockwise by 90°, and the plugging column 302 on the right side of the reference inner frame 2 rotates counterclockwise by 90°. The through holes 3021 on them are all staggered from the assembly groove, thereby plugging the side slot 301. Refer to Figure 1 ; when the movable inner frame 3 moves away from the reference inner frame 2, the plugging column 302 on the left side of the reference inner frame 2 rotates counterclockwise by 90°, and the plugging column 302 on the right side of the reference inner frame 2 rotates clockwise by 90°. The through holes 3021 on them all coincide with the assembly groove, thereby opening the side slot 301. Refer to Figure 2 , which can further increase the ventilation volume of a single battery cell.

[0060] As Figure 2 and Figure 4As shown, two groups of main push blocks 10 are installed in the upper limit sliding manner on the main outer frame 101, and the main push blocks 10 are pushed up and down by external force and act on the push assembly; the push assembly includes a cylindrical pin 8 and a vertical push bar 9, and the vertical push bar 9 is installed on the main outer frame 101 in a limited sliding manner. One end of the vertical push bar 9 extends into the Z-axis block frame 7 and is fixedly connected with the cylindrical pin 8, and the other end of the vertical push bar 9 is fixedly connected to the main push block 10, and an oblique groove 701 for accommodating the cylindrical pin 8 is opened through the side wall of the Z-axis block frame 7. By setting the cylindrical pin 8 and the vertical push bar 9 to be used in conjunction with the oblique groove 701, the up and down movement of the main push block 10 can be converted into the horizontal opposite movement of the two groups of Z-axis block frames 7, so that the battery module 1 can quickly switch between the two states of sealing and ventilation and heat dissipation.

[0061] Specifically, when the main push block 10 is pushed upward by an external force, the vertical push bar 9 also drives the cylindrical pin 8 thereon to move upward, and the cylindrical pin 8 acts on the oblique groove 701, and the cylindrical pin 8 moves from the left end (such as Figure 3 ) moves to the right end of the oblique slot 701 (as shown in Figure 2 As shown in the figure, because the cylindrical pin 8 only moves up and down, and its left and right positions remain unchanged, the position of the Z-axis baffle frame 7 will be moved from protruding from the main outer frame 101 to inside the main outer frame 101 due to the limiting extrusion of the cylindrical pin 8; that is, the Z-axis baffle frame 7 is subjected to force and pushes the movable inner frame 3 to move toward the direction of the reference inner frame 2. At this time, the reference inner frame 2, multiple movable inner frames 3 and the Z-axis baffle frame 7 fit each other. At the same time, driven by the moving gear 304, the fixed rack 305 and the central axis 303, the blocking column 302 blocks the side slot 301, so that the battery module 1 is in a completely closed state, which has a sealing protection effect on the cylindrical battery cell 4. Figure 1 ;

[0062] When the external force cancels the squeezing force on the main push block 10, under the action of the repulsive force generated between the adjacent magnetic sheets 5, the Z-axis baffle frame 7 releases the pushing force on the movable inner frame 3, and the multiple movable inner frames 3 are also equidistantly translated and unfolded on both sides of the reference inner frame 2, and the oblique groove 701 of the Z-axis baffle frame 7 acts on the cylindrical pin 8, so that the vertical push bar 9 is forced to drive the main push block 10 to move downward. At the same time, under the action of the moving gear 304, the fixed rack 305 and the central axis 303 again, the blocking column 302 opens the side slot 301, and the battery module 1 can be ventilated and cooled in the four directions of front, back, left and right. Figure 3 .

[0063] like Figures 6 - 12As shown in the figure, an anti-corrosion energy storage battery for marine vessels includes a plurality of cell modules 1, an intermediate housing 11, and an outer housing 12; the self-frame of the cell module 1 provides a primary sealing protection for the cylindrical cells 4; a plurality of cell modules 1 are arranged inside the intermediate housing 11, and the number of cell modules 1 is set to be an odd number. The main outer frame 101 of the cell module 1 located in the exact middle remains fixed; the cell modules 1 on both sides thereof can move as a whole; and the plurality of cell modules 1 perform an equidistant translational movement driven by a main driving component for realizing the ventilation and heat dissipation of the cell module 1 itself; the intermediate housing 11 wraps the plurality of cell modules 1 as a whole to achieve a secondary sealing protection for the cylindrical cells 4; the outer housing 12 is arranged outside the intermediate housing 11, and the outer housing 12 is in a long-sealed state to achieve a triple sealing protection for the cylindrical cells 4.

[0064] Furthermore, Z-axis through grooves 13 and X-axis through grooves 14 are successively formed on both sides of the Z-axis and both sides of the X-axis of the intermediate housing 11 to achieve the ventilation and heat dissipation of the intermediate housing 11; an X-axis plug plate 15 is clamped in the X-axis through groove 14, and the X-axis plug plate 15 is fixedly arranged on the adjacent cell module 1. When the Z-axis blocking frame 7 on the cell module 1 expands outwards, it can block the Z-axis through groove 13; with such a setting, the intermediate housing 11 and the cell module 1 are in an alternating sealing state.

[0065] The advantages of this energy storage battery are as follows: the outer housing 12 is set in a long-closed state to form a permanent barrier, ensuring that the core area of the battery is always in a high protection state and preventing the intrusion of salt spray, moisture, and corrosive gases; and the second and first sealing structures work alternately. Under normal working conditions, the intermediate housing 11, as the second sealing structure, is opened, and the first sealing structure is closed, and a ventilation channel is formed between the intermediate housing 11 and the outer housing 12, which can dissipate heat from the whole cell module 1; in the case of a sharp increase in the internal heat of the cell module 1, the intermediate housing 11, as the second sealing structure, is closed, and the first sealing structure is opened, and the unit frames in the cell module 1 are separated from each other, so that each single cell can be evenly ventilated and cooled.

[0066] As Figures 9 - 12 shown in the figure, a connecting column 16 is fixedly connected to the bottom of each cell module 1. The connecting column 16 extends into the bottom wall of the intermediate housing 11 and is connected to the main driving component; the main driving component includes a plug cam 17 and an electric push cylinder 18. The plug cam 17 performs a Z-axis linear movement under the push of the electric push cylinder 18. The connecting column 16 is clamped in the wheel groove of the plug cam 17. The plug cam 17 is installed on the intermediate housing 11 with limited sliding, and the wheel groove on the plug cam 17 consists of a straight groove in the middle and a plurality of inclined grooves on both sides. The slopes of the plurality of inclined grooves increase successively in multiples from the inside to the outside.

[0067] Specifically, when the piston rod of the electric push cylinder 18 extends outward and pushes the plug cam 17, the connecting column 16 drives the battery cell module 1 to expand to both sides under the action of the groove of the plug cam 17. At this time, the X-axis plug plate 15 also moves accordingly and blocks the X-axis through groove 14. When the piston rod of the electric push cylinder 18 retracts inward and pulls the plug cam 17, the connecting column 16 drives the battery cell module 1 to close in the middle under the action of the groove of the plug cam 17. At this time, the X-axis plug plate 15 also moves accordingly and opens the X-axis through groove 14.

[0068] As Figures 10 - 12 shown, a linkage assembly is provided on the plug cam 17 for pressing the main push block 10 on the battery cell module 1 in the exact middle. The linkage assembly includes an active push plate 19, a first push block 20, an active toothed plate 21, a spur gear 22, a driven toothed plate 23, and a second push block 24. The active push plate 19 and the active toothed plate 21 are both fixedly connected to the plug cam 17. The first push block 20 and the second push block 24 both push a set of main push blocks 10 upward. One side of the bottom of the first push block 20 and the second push block 24 is shaped like an inclined plane, and a limiting block 25 protrudes on the other side. A return spring 26 is provided above the limiting block 25. The two sides of the spur gear 22 are sequentially meshed with the active toothed plate 21 and the driven toothed plate 23, so that the driven toothed plate 23 moves in the opposite direction to the active push plate 19 and sequentially pushes the second push block 24 and the first push block 20.

[0069] Furthermore, through the design of the active push plate 19, the first push block 20, the active toothed plate 21, the spur gear 22, the driven toothed plate 23, and the second push block 24, the linear motion of the plug cam 17 can be converted into an upward driving force on the two groups of main push blocks 10 on the battery cell module 1 in the exact middle. So that the battery cell module 1 in the exact middle can keep its own position unchanged, and the moving inner frame 3 and the Z-axis blocking frame 7 on it can also be smoothly unfolded, so that the primary sealing structures on all the battery cell modules 1 can be normally opened and closed.

[0070] As Figure 8 and Figure 9 shown, a plurality of active slots 1101 equal in number to the main push blocks 10 are spaced on the bottom wall of the middle housing 11. The lower parts of the main push blocks 10 are all shaped like arcs, and the main push blocks 10 move linearly with the battery cell module 1. When multiple battery cell modules 1 expand to both sides, except for the main push blocks 10 on the battery cell module 1 in the exact middle, all the remaining main push blocks 10 are released from the extrusion effect and just fit into the active slots 1101. At this time, the battery cell modules 1 in cooperation with them are in a ventilation and heat dissipation state. When multiple battery cell modules 1 close in the middle, except for the main push blocks 10 on the battery cell module 1 in the exact middle, all the remaining main push blocks 10 move away from the active slots 1101 and are upwardly extruded by the bottom wall of the middle housing 11. At this time, the battery cell modules 1 in cooperation with them are in a sealed state.

[0071] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
