DETAILED DESCRIPTION

[0033] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0034] Embodiment 1, as Figure 1-Figure 10As shown, a container-type lithium battery energy storage group comprises a battery box shell 1, wherein fixing frames 2 are equidistantly fixed inside the battery box shell 1, and lithium battery packs 3 are arranged between the fixing frames 2. A door cover 4 is arranged in front of the battery box shell 1, and a rain blocking block 5 is fixed to the back of the upper end of the battery box shell 1. The inner sleeve of the rain blocking block 5 is connected to a limit shaft 6, and the upper and lower ends of the side of the limit shaft 6 are respectively fixed with through-hole blocks 7, and the through-hole block 7 is semicircular. A ventilation block 8 is fixed inside the through-hole block 7, and a convex rod 9 is connected inside the ventilation block 8. A filter mesh block 10 sleeved inside the through-hole block 7 is fixed at the other end of the convex rod 9, and a desiccant bag 12 is placed between the ventilation block 8 and the filter mesh block 10. A heat dissipation fan 13 corresponding to the filter mesh block 10 is fixed on the rain blocking block 5. By closing the door cover 4 and then starting the heat dissipation fan 13, the heat dissipation fan 13 guides the cold air from the outside through the filter mesh block 10. The gas entering the through-hole block 7 contacts with the desiccant bag 12, so that the filter mesh block 10 filters the dust in the air, and the desiccant bag 12 absorbs moisture from the gas. The gas after moisture absorption enters the battery box shell 1 through the breathable block 8. The gas entering the battery box shell 1 cools down the lithium battery pack 3 through the fixing frame 2, so that the gas becomes hot. Then the heated gas enters the through-hole block 7 through the breathable block 8 in the lower through-hole block 7. At this time, the heated gas can dry the desiccant bag 12 in the lower through-hole block 7. The gas is then discharged through the breathable block 8 inside the lower through-hole block 7, so that the gas can recoil and clean the breathable block 8. Such a design enables the device not only to filter and moisture-proof the lithium battery pack 3, but also to rotate the limit shaft 6 to exchange the positions of the two through-hole blocks 7, dry the desiccant bag 12, and recoil and clean the dust from the breathable block 8.

[0035] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0036] Embodiment 2, as Figure 6-Figure 10 As shown, a second fixed block 22 is fixedly connected to the side of the through-hole block 7, a convex ring 23 is movably sleeved inside the second fixed block 22, a hollow rod 24 is fixedly connected to the top of the convex ring 23, and rotating blades 25 are respectively fixedly connected to the two ends of the outer surface of the hollow rod 24, and the other end of the rotating blades 25 is in contact with the filter mesh block 10. When the hollow rod 24 rotates, the hollow rod 24 drives the rotating blades 25 to deflect. At this time, since the heat dissipation fan 13 has been blowing air to the filter mesh block 10, the heat dissipation fan 13 will blow the second fixed block 22 and the through-hole block 7 to one side as a whole through the deflected rotating blades 25, the hollow rod 24 and the convex ring 23, thereby achieving the purpose of rotating the through-hole block 7.

[0037] A spiral groove 26 is provided inside the hollow rod 24, and an iron plug rod 21 is sleeved inside the hollow rod 24. A round-headed protrusion 27 is fixed to the side of the iron plug rod 21, and the other end of the round-headed protrusion 27 extends to the inside of the spiral groove 26. Through the design of the spiral groove 26 and the round-headed protrusion 27, when the iron plug rod 21 moves downward, the iron plug rod 21 drives the round-headed protrusion 27 to move downward along the inner wall of the spiral groove 26, and then the round-headed protrusion 27 drives the hollow rod 24 and the rotating fan blade 25 to deflect through the spiral groove 26.

[0038] The lower end of the iron plug rod 21 passes through the second fixed block 22 and is fixedly sleeved with the movable block 18. The bottom of the movable block 18 is fixedly connected with the second rigid spring 19. The lower end of the second rigid spring 19 is fixedly connected with the first fixed block 20. The side of the first fixed block 20 is fixedly connected to the side of the through-hole block 7. At this time, the second rigid spring 19 is in a stretched state, so that the second rigid spring 19 can pull the iron plug rod 21 downward through the movable block 18, thereby achieving the purpose of moving the iron plug rod 21 downward.

[0039] The upper end of the iron plug rod 21 is movably sleeved with a card hole block 29, and a magnet block 28 is fixed to the top of the card hole block 29. The side of the magnet block 28 is fixedly connected to the side of the battery box shell 1. Through the design of the iron plug rod 21, the card hole block 29 and the magnet block 28, the magnet block 28 can attract the iron plug rod 21 to the inside of the card hole block 29 to fix the second fixing block 22 and the through hole block 7, thereby achieving the purpose of fixing the through hole block 7.

[0040] A side notch 14 is provided inside the through hole block 7, and an inclined semi-ring block 16 for placing the desiccant bag 12 is movably sleeved inside the side notch 14, and a moving block 15 is fixed at the bottom of the inclined semi-ring block 16, and one end of the moving block 18 extends into the side notch 14 and is fixedly connected to the moving block 15. When the desiccant bag 12 inside the through hole block 7 becomes heavier due to dehumidification of the gas, the desiccant bag 12 will squeeze the inclined semi-ring block 16 and move downward, and then the inclined semi-ring block 16 will push the moving block 18 to move downward along the inner wall of the side notch 14 through the moving block 15, and then the moving block 18 will drive the iron plug rod 21 to move downward, and at this time, the second rigid spring 19 can pull the moving block 18 to move downward, so that the moving block The movable block 18 can more easily pull the iron rod 21 out of the inside of the card hole block 29, thereby releasing the fixing effect on the through hole block 7. At the same time, the iron rod 21 will drive the hollow rod 24 and the rotating fan blades 25 to rotate through the round head protrusion 27 and the spiral groove 26, so that the heat dissipation fan 13 that has been blowing air to the filter mesh block 10 can blow the rotating fan blades 25 and the hollow rod 24, and then the hollow rod 24 drives the through hole block 7 to rotate to one side through the convex ring 23 and the second fixed block 22, so that the two through hole blocks 7 can be rotated and exchanged by the force of the heat dissipation fan 13 blowing the rotating fan blades 25 and the gravity of the desiccant bag 12 itself, and then the through hole block 7 drives the limit shaft 6 to rotate along the inner wall of the rain blocking block 5.

[0041] Based on the second embodiment, the solution in the second embodiment is further detailed in combination with the following specific working method, as described below for details.

[0042] Embodiment three, as Fig.10As shown, a sloped push block 17 is fixedly connected to the middle part of the lower end of the filter block 10, and the other end of the sloped push block 17 is in contact with the slope of the sloped semi-ring block 16. When the filter block 10 is blocked by external dust, the heat dissipation fan 13 will push the filter block 10 to move along the inner wall of the through-hole block 7, and then the filter block 10 will drive the sloped push block 17 to push the sloped semi-ring block 16 to move downward, so that the sloped semi-ring block 16 drives the iron plug rod 21 to move downward through the moving block 15 and the movable block 18, so that the iron plug rod 21 is separated from the inside of the card hole block 29, and the iron plug rod 21 drives the hollow rod 24 and the rotating fan blade 25 to rotate through the spiral groove 26 and the round head protrusion 27, so that the heat dissipation fan 13 can push the through-hole block 7 to rotate and adjust through the rotating fan blade 25. When the iron plug rod 21 is separated from the magnet block 28, the second rigid spring 19 will pull the iron plug rod through the movable block 18 21 moves downward, thereby causing the iron plug rod 21 to pull the round head protrusion 27 to move the lowest end of the spiral groove 26, so that the iron plug rod 21 drives the rotating blade 25 to rotate ninety degrees through the round head protrusion 27 and the spiral groove 26, thereby causing the rotating blade 25 to correspond horizontally to the heat dissipation fan 13, so that the other through-hole block 7 drives the rotating blade 25 to rotate when it can cut the gas blown to the filter screen block 10 by the heat dissipation fan 13, and then when the other through-hole block 7 drives the iron plug rod 21 to rotate to the magnet block 28 through the second fixing block 22, the magnet block 28 will attract the iron plug rod 21 into the inside of the card hole block 29 to fix the through-hole block 7, and at the same time, the iron plug rod 21 will drive the hollow rod 24 and the rotating blade 25 to rotate through the round head protrusion 27 and the spiral groove 26, so that the rotating blade 25 vertically corresponds to the heat dissipation fan 13, thereby achieving the purpose of automatically replacing the through-hole block 7 when the filter screen block 10 is blocked.

[0043] like Figure 7 As shown, the outer surface of the convex rod 9 is movably sleeved with a first rigid spring 11 located between the filter mesh block 10 and the air-permeable block 8, one end of the first rigid spring 11 is fixedly connected to the air-permeable block 8, and the other end of the first rigid spring 11 is fixedly connected to the filter mesh block 10. Through the design of the first rigid spring 11, the first rigid spring 11 can apply pressure to the filter mesh block 10, so that the gas blown by the heat dissipation fan 13 cannot blow the filter mesh block 10 to move toward the inside of the through-hole block 7 at will.

[0044] During specific use, in a container-type lithium battery energy storage group, when the filter block 10 is blocked by external dust, the heat dissipation fan 13 will push the filter block 10 to move toward the inside of the through-hole block 7, so that the filter block 10 pushes the inclined semi-ring block 16 downward through the inclined push block 17, so that the inclined semi-ring block 16 drives the iron plug rod 21 to move downward and disengage from the inside of the card hole block 29 through the moving block 15 and the movable block 18, so that the iron plug rod 21 drives the hollow rod 24 and the rotating fan blades 25 to deflect the angle through the spiral groove 26 and the round head protrusion 27. At this time, the heat dissipation fan 13 that has been blowing air on the filter block 10 can blow the hollow rod 24 through the rotating fan blades 25, so that the hollow rod 24 pushes the through-hole block 7 to rotate to one side through the convex ring 23 and the second fixed block 22, so that the two through-hole blocks 7 can be blown by the heat dissipation fan 13. The force of the rotating fan blades 25 The iron plug rod 21 is rotated and exchanged with the gravity of the desiccant bag 12 itself, and the through-hole block 7 drives the limit shaft 6 to rotate along the inner wall of the rain-blocking block 5. When the iron plug rod 21 is separated from the magnet block 28, the second rigid spring 19 pulls the iron plug rod 21 downward through the movable block 18, and then the iron plug rod 21 drives the rotating fan blades 25 to correspond horizontally with the heat dissipation fan 13 through the round head protrusion 27 and the spiral groove 26. When the through-hole block 7 drives the iron plug rod 21 to rotate to the magnet block 28 through the second fixed block 22, the magnet block 28 will attract the iron plug rod 21 into the interior of the card hole block 29 to fix the through-hole block 7, and the iron plug rod 21 drives the hollow rod 24 to rotate through the round head protrusion 27 and the spiral groove 26, so that the rotating fan blades 25 correspond vertically with the heat dissipation fan 13, so as to achieve the purpose of automatically replacing the through-hole block 7 when the filter mesh block 10 is blocked.

[0045] When the desiccant bag 12 inside the through-hole block 7 becomes heavier due to dehumidification of the gas, the desiccant bag 12 squeezes the inclined semi-ring block 16 to move downward, and then the inclined semi-ring block 16 pushes the iron plug 21 downward through the moving block 15 and the movable block 18 to disengage from the inside of the hole block 29, and the iron plug 21 drives the hollow rod 24 to rotate through the round head protrusion 27 and the spiral groove 26, and the rotating fan blade 25 deflects an angle, so that the heat dissipation fan 13 blows the through-hole block 7 to rotate to one side through the rotating fan blade 25, and stops when the other through-hole block 7 drives the iron plug 21 to be adsorbed and fixed by the magnet block 28 and the hole block 29, thereby achieving the purpose of automatically replacing and drying the desiccant bag 12.

[0046] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
