Description

Technical Field

[0001] This utility model relates to the field of moisture-proof technology for energy storage containers, and in particular to a moisture-proof device for energy storage containers. Background Technology

[0002] As the core equipment of an energy storage system, the stability of the internal environment of the energy storage container is a key factor affecting the energy storage performance. Among them, humidity control of the internal environment of the energy storage container is crucial. If the humidity inside the energy storage container is too high, the electronic components inside the energy storage container are easily affected by moisture, which will lead to a decrease in energy storage performance, a reduction in service life, and even serious safety hazards.

[0003] Currently, there are two main methods for moisture control inside energy storage containers: The first is to place desiccants inside the container, utilizing their adsorption properties to remove moisture from the air. However, the adsorption capacity of desiccants is limited, requiring regular manual replacement and resulting in high maintenance costs. The second method uses mechanical ventilation devices and vents on the container to periodically ventilate and dehumidify the interior. However, in practice, opening and closing these vents largely relies on manual operation, which is cumbersome and prone to human error. For example, if vents are not closed during non-ventilation periods, external moisture and dust can enter the container, affecting its energy storage performance. Therefore, there is an urgent need to develop a new type of moisture control device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a moisture-proof device for energy storage containers, which aims to solve the technical problems of existing methods for moisture-proofing the interior of energy storage containers, such as the method of placing desiccant inside the energy storage container, which requires manual replacement periodically and has high maintenance costs; and the method of regularly ventilating the interior of the container through mechanical ventilation moisture-proof devices and ventilation vents on the energy storage container, which requires manual opening and closing of ventilation vents, which is cumbersome and prone to human error.

[0005] The purpose of this utility model is to provide a moisture-proof device for an energy storage container. The energy storage container includes a container body, the container body includes a frame, two doors rotatably connected to the frame, and a first side plate opposite to the two doors. The first side plate is provided with two first ventilation openings, and the doors are provided with second ventilation openings.

[0006] The moisture-proof device includes a fan assembly, a first cover plate assembly, a transmission assembly connected to the first cover plate assembly, and a second cover plate assembly linked to the transmission assembly. The fan assembly is disposed near the air inlet of the first vent, and the first cover plate assembly is used to cover the air outlet of the second vent.

[0007] The second cover plate assembly includes multiple fins and a connecting rod connected to the top of the multiple fins. The end of the connecting rod is provided with the transmission assembly. The bottom end of the fin is rotatably connected to the bottom end of the second vent through a second torsion spring. When the second torsion spring is in its natural state, the surfaces of the multiple fins are partially stacked to cover the second vent.

[0008] Compared to existing technologies, the beneficial effects of this utility model's moisture-proof device for energy storage containers are as follows: By setting a transmission component to achieve precise linkage between the first cover assembly and the second cover assembly, the first and second cover assemblies can automatically close the first and second ventilation openings during non-ventilation periods. Specifically, during ventilation periods, a fan assembly introduces dry air from the outside, and the fan airflow drives the first cover assembly to open. Under the action of the transmission component, the second cover assembly is driven to open, realizing the circulation of air inside the container with dry air from the outside, quickly and effectively reducing the humidity inside the container. During non-ventilation periods, the upper and lower cover plates of the first cover assembly can automatically cover the first ventilation opening under the return force of the first torsion spring, and the multiple fins of the second cover assembly can automatically overlap to cover the second ventilation opening under the return force of the second torsion spring. This effectively prevents external moisture from entering the container through the first and second ventilation openings during non-ventilation periods, ensuring that the container remains dry at all times. The entire process requires no manual intervention, effectively preventing external moisture and dust from entering the container during non-ventilation periods, thus ensuring the energy storage performance of the energy storage container.

[0009] In addition, the moisture-proof device for energy storage containers according to the present invention may also have the following additional technical features:

[0010] Furthermore, the first cover plate assembly includes an upper cover plate and a lower cover plate. The upper cover plate and the lower cover plate are rotatably connected to the upper and lower sides of the air outlet of the first vent via a first torsion spring. A gap is provided between the upper cover plate and the lower cover plate. When the first torsion spring is in its natural state, the upper cover plate and the lower cover plate respectively cover the upper and lower ends of the first vent.

[0011] Furthermore, the transmission assembly includes a transmission plate and two transmission rods respectively connected to both ends of the transmission plate, with one end of the transmission rod away from the transmission plate connected to the side of the upper cover plate opposite to the fan assembly.

[0012] Furthermore, the transmission rod includes a first transmission rod portion, a second transmission rod portion connected to the first transmission rod portion, a third transmission rod portion connected to the second transmission rod portion, and a fourth transmission rod portion connected to the third transmission rod portion.

[0015] The transmission plate has inclined surfaces at both ends along the width direction of the frame. The top of the inclined surface is located outside the edge of the second vent, and the bottom of the inclined surface extends beyond the edge of the second vent and is located inside the space where the second vent is located. One end of a connecting rod is provided diagonally above the inclined surface.

[0016] Furthermore, the fan assembly includes a mounting frame and a fan disposed inside the mounting frame. One end of the mounting frame is fixedly connected to the side of the first side plate opposite to the door. The fan is positioned facing the second vent, and there is a gap between the fan and the first cover plate assembly.

[0017] Furthermore, the fin plate includes a rotating rod portion, a fin plate portion connected to the rod body of the rotating rod portion, and a connecting rod portion disposed at the top of the rotating rod portion. The angle between the plate surface of the fin plate portion and the axial direction of the connecting rod portion is an obtuse angle. One end of the connecting rod portion away from the rotating rod portion is fixedly connected to the connecting rod. The bottom end of the rotating rod portion is rotatably connected to the bottom end of the second vent through the second torsion spring.

[0018] Furthermore, the box body also includes a top plate at the top of the box frame, a bottom plate at the bottom of the box frame, and two second side plates on opposite sides of the box frame.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] Please see Figures 1 to 8The image shows a moisture-proof device for an energy storage container according to the present invention. The energy storage container includes a container body 10, which includes a frame 11, two doors 12 rotatably connected to the frame 11, a first side plate 13 opposite to the two doors 12, a top plate 15 at the top of the frame 11, a bottom plate 16 at the bottom of the frame 11, and two second side plates 14 on two opposite sides of the frame 11. The top plate 15, bottom plate 16, two second side plates 14, two doors 12, and first side plates 13 together form a storage space for storing various energy storage devices. Specifically, in this embodiment, one side of the door 12 is rotatably connected to the frame 11 via a connecting shaft, so that the two doors 12 can be opened and closed flexibly. When the two doors 12 are closed, the opposite sides of the two doors 12 are tightly abutted, and the remaining side doors on the two doors 12 are tightly fitted to the frame 11. The door 12 is provided with a second ventilation opening 102. Furthermore, the first side plate 13 is provided with two first ventilation openings 101, which are arranged side by side along the width direction of the frame 11.

[0034] In this embodiment, the moisture-proof device includes a fan assembly 20, a first cover plate assembly 30, a transmission assembly 40 connected to the first cover plate assembly 30, and a second cover plate assembly 50 linked with the transmission assembly 40. The fan assembly 20 is located near the air inlet of the first vent 101. The fan assembly 20 includes a mounting frame 21 and a fan 22 located inside the mounting frame 21. One end of the mounting frame 21 is fixedly connected to the side of the first side plate 13 facing away from the door 12. The fan 22 is located facing the second vent 102, and there is a gap between the fan 22 and the first cover plate assembly 30. By activating the fan 22, dry air from the outside is introduced into the box 10 to promote air circulation inside the box 10, thereby effectively reducing the humidity inside the box 10.

[0035] As an example, the first cover assembly 30 is used to cover the air outlet of the second vent 102. The first cover assembly 30 includes an upper cover 31 and a lower cover 32. The upper cover 31 and the lower cover 32 are rotatably connected to the upper and lower sides of the air outlet of the first vent 101 via a first torsion spring 33. There is a gap between the upper cover 31 and the lower cover 32. When the first torsion spring 33 is in its natural state, the upper cover 31 and the lower cover 32 cover the upper and lower ends of the first vent 101 respectively, preventing external moisture from entering the interior of the housing 10 when not ventilated. When the fan 22 is started, the pressure generated by the airflow overcomes the elastic force of the first torsion spring 33, causing the upper cover 31 to flip upward and the lower cover 32 to flip downward, no longer covering the first vent 101, thus achieving the purpose of ventilation.

[0036] As an example, the transmission assembly 40 includes a transmission plate 42 and two transmission rods 41 respectively connected to both ends of the transmission plate 42. One end of each transmission rod 41, away from the transmission plate 42, is connected to the side of the upper cover 31 opposite to the fan assembly 20. In this embodiment, as... Figure 3 and Figure 4 As shown, the transmission rod 41 includes a first transmission rod portion 411, a second transmission rod portion 412 connected to the first transmission rod portion 411, a third transmission rod portion 413 connected to the second transmission rod portion 412, and a fourth transmission rod portion 414 connected to the third transmission rod portion 413. Specifically, the first transmission rod portion 411 is arranged along the width direction of the frame 11, and the rod body of the first transmission rod portion 411 is fixedly connected to the middle part of the side of the upper cover plate 31 away from the fan assembly 20, so as to ensure that the first transmission rod portion 411 can move upward synchronously with the upper cover plate 31 as it flips upward during the upward flipping process. The second transmission rod 412 is arranged along the height direction of the housing frame 11, the third transmission rod 413 is arranged along the length direction of the housing frame 11, and the fourth transmission rod 414 is arranged along the width direction of the housing frame 11. The end of the fourth transmission rod 414 away from the third transmission rod 413 is connected to the transmission plate 42. It should be understood that this multi-segment transmission rod 41 structure with different directions is designed according to the internal spatial layout of the housing 10. While ensuring that the force can be effectively transmitted, it does not occupy the space inside the housing 10 used for placing energy storage devices, thus greatly improving the space utilization rate inside the housing 10.

[0037] Furthermore, the transmission plate 42 is located at the top of the abutment of the two box doors 12. One side of the transmission plate 42 is in close contact with the inner surface of the two box doors 12, and the other side of the transmission plate 42 is fixedly connected to the end of the fourth transmission rod 414 away from the third transmission rod 413. The transmission plate 42 has inclined surfaces at both ends along the width direction of the box frame 11. The top of the inclined surface is located outside the edge of the second vent 102, and the bottom of the inclined surface extends beyond the edge of the second vent 102 and is located inside the space where the second vent 102 is located. One end of the connecting rod 51 is provided diagonally above the inclined surface, and the inclined surface is used to abut against the connecting rod 51. As a specific example, in this embodiment, the transmission plate 42 is a trapezoidal plate structure. The small end of the trapezoidal plate structure is located near the top of the second vent 102, and the end face of the small end is slightly higher than the top end face of the connecting rod 51. The end face of the large end of the trapezoidal plate structure is located below the bottom end face of the connecting rod 51, so that a connecting rod 51 is respectively located above the two inclined surfaces of the trapezoidal plate structure. In this way, when the upper cover plate 31 is flipped upward, the first transmission rod part 411 connected to it moves upward synchronously, driving the second transmission rod part 412 connected to the first transmission rod part 411. Synchronously raised, under the action of force transmission, one end of the third transmission rod 413 that is connected to the second transmission rod 412 is raised accordingly, while the end of the third transmission rod 413 that is away from the second transmission rod 412 moves downward. This causes the end of the fourth transmission rod 414 that is connected to the transmission plate 42 to be raised upward. The inclined surface on the transmission plate 42 abuts against the end of the connecting rod 51, thereby pushing the connecting rod 51 to move horizontally away from the abutment of the two boxes 12, thereby triggering the second cover plate assembly 50 and completing the linkage process between the first cover plate assembly 30 and the second cover plate assembly 50.

[0038] The transmission assembly 40 in this embodiment also includes a sliding seat 43, which is fixed on the first side plate 13 on the side opposite to the door 12. The second transmission rod 412 is slidably inserted into the sliding seat 43. The sliding seat 43 provides guidance and support for the movement of the second transmission rod 412, ensuring a smooth and stable transmission process.

[0039] As an example, the second cover assembly 50 includes multiple fins 52 and a connecting rod 51 connected to the top of the multiple fins 52. The end of the connecting rod 51 is provided with a transmission assembly 40. The bottom end of the fins 52 is rotatably connected to the bottom end of the second vent 102 through a second torsion spring 53. When the second torsion spring 53 is in its natural state, the surfaces of the multiple fins 52 are partially stacked to cover the second vent 102, effectively preventing external moisture from entering the interior of the housing 10 through the second vent 102 during non-ventilation periods. Specifically, the fin 52 includes a rotating rod portion 521, a fin portion 522 connected to the rod body of the rotating rod portion 521, and a connecting rod portion 523 located at the top of the rotating rod portion 521. The angle between the plate surface of the fin portion 522 and the axial direction of the connecting rod portion 523 is an obtuse angle. One end of the connecting rod portion 523 away from the rotating rod portion 521 is fixedly connected to the connecting rod 51. The bottom end of the rotating rod portion 521 is rotatably connected to the bottom end of the second vent 102 through the second torsion spring 53. When the connecting rod 51 moves horizontally under the action of the resistance force of the transmission plate 42, the bottom end of the rotating rod portion 521 of the fin 52 will rotate against the restoring elastic force of the second torsion spring 53, so that the plate surface between two adjacent fins 52 appears for ventilation, thereby realizing the opening of the second vent 102.

[0040] Furthermore, the moisture-proof device also includes a desiccant assembly 60 located inside the housing 10. The desiccant assembly 60 includes multiple placement boxes 61 and desiccant 62 located inside the placement boxes 61. The desiccant 62 is used to absorb moisture in the internal space of the housing 10 to further reduce the humidity inside the housing 10. The placement boxes 61 are along the length of the housing frame 11, and one side of the placement box 61 is fixedly connected to the surface of the second side plate 14. This arrangement makes reasonable use of the side space of the housing 10, achieving the moisture-proof function without occupying too much effective space inside the housing, ensuring the normal placement and operation space of the energy storage equipment. Furthermore, multiple ventilation holes 601 are provided on the side of the placement box 61 facing away from the second side plate 14. The design of the ventilation holes 601 allows the desiccant 62 to fully contact the air inside the housing, improving the drying efficiency. As a specific example, in this embodiment, three placement boxes 61 are provided on the side where the second side plate 14 is located. The three placement boxes 61 are evenly spaced along the height direction of the frame 11, and the desiccant 62 placed in the placement box 61 is activated carbon.

[0041] In practical use, the working principle of the moisture-proof device for the energy storage container of this utility model is as follows: During non-ventilation periods, the first torsion spring 33 is in its natural state, and the upper cover plate 31 and the lower cover plate 32, under the elastic force of the first torsion spring 33, respectively cover the upper and lower ends of the first ventilation opening 101. At the same time, the second torsion spring 53 is also in its natural state, and the surfaces of the multiple fins 52 in the second cover plate assembly 50 are partially stacked to cover the second ventilation opening 102, effectively preventing external moisture from entering the interior of the container 10. Meanwhile, the desiccant 62 in the desiccant assembly 60 located inside the container 10 will come into contact with the air inside the container through the multiple vents 601 on the placement box 61 to continuously absorb moisture from the air inside the container 10, thereby reducing the humidity inside the container 10.

[0042] When ventilation is required inside the housing 10, the fan 22 can be activated to introduce dry outside air into the housing 10. During air circulation, the pressure on the surfaces of the upper cover 31 and the lower cover 32 will overcome the restoring force of the first torsion spring 33, causing the upper cover 31 to flip upward and the lower cover 32 to flip downward, opening the air outlet of the first vent 101. As the upper cover 31 flips upward, the first transmission rod 411 connected to the upper cover 31 moves upward synchronously. The upward movement of the first transmission rod 411 drives the second transmission rod 412 connected to it to rise upward. The second transmission rod 412 slides upward within the sliding seat 43, ensuring smooth and guided movement. One end of the third transmission rod 413 connected to the second transmission rod 412 also rises. Under the transmission of force, the end of the third transmission rod 413 away from the second transmission rod 412 moves downward, thereby driving the end of the fourth transmission rod 414 connected to the transmission plate 42 to rise upward.

[0043] Next, the inclined surfaces at both ends of the transmission plate 42 will abut against the ends of the corresponding connecting rods 51, causing the connecting rods 51 to move horizontally away from the contact point of the door 12. The movement of the connecting rods 51 drives the connecting rods 523 of the multiple fins 52 connected to them to move. The bottom end of the rotating rod 521 of the fin 52 rotates against the restoring force of the second torsion spring 53, causing the position of the fin 522 to change. A gap for ventilation appears between adjacent fins 52, and the second vent 102 opens, realizing the circulation of air inside the box with dry air outside, and reducing the humidity inside the box.

[0044] During ventilation, the desiccant assembly 60 continues to operate, absorbing any moisture that may still remain inside the chamber after ventilation, further ensuring a dry environment inside the chamber. When the fan 22 stops working and the air pressure disappears, the first torsion spring 33 and the second torsion spring 53 respectively restore the first cover assembly 30 and the second cover assembly 50 to their initial state of covering the vents, preventing external moisture from re-entering.

[0045] In summary, the beneficial effects of the moisture-proof device for energy storage containers of this utility model are as follows: By setting a transmission component to achieve precise linkage between the first cover assembly and the second cover assembly, the first and second cover assemblies can automatically close the first and second ventilation openings during non-ventilation periods. Specifically, during ventilation periods, a fan assembly is used to introduce dry air from the outside, and the fan airflow drives the first cover assembly to open. Under the action of the transmission component, the second cover assembly is driven to open, realizing the circulation of air inside the container with dry air from the outside, and quickly and effectively reducing the humidity inside the container. During non-ventilation periods, the upper and lower cover plates of the first cover assembly can automatically cover the first ventilation opening under the return force of the first torsion spring, and the multiple fins of the second cover assembly can automatically overlap to cover the second ventilation opening under the return force of the second torsion spring. This effectively prevents external moisture from entering the container from the first and second ventilation openings during non-ventilation periods, ensuring that the container remains dry at all times. The entire process requires no manual intervention, effectively avoiding the phenomenon of external moisture and dust entering the container during non-ventilation periods, and ensuring the energy storage performance of the energy storage container.
