Description
Technical Field
[0001] This utility model relates to the field of energy storage device technology, and in particular to an energy storage box and energy storage system. Background Technology
[0002] In an energy storage system, batteries are installed inside an energy storage box. During the charging and discharging process of the batteries, a large amount of heat is released.

Driven by the fans, outside air enters the energy storage tank through the ventilation holes to achieve air cooling. During the cooling process, external dust particles and other impurities can easily enter the energy storage tank through the ventilation holes, leading to dust accumulation over prolonged use. This can potentially cause safety risks such as battery short circuits, reducing the safety and reliability of the energy storage tank. Utility Model Content

[0043] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0046] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0047] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0048] This embodiment proposes an energy storage system, which includes an energy storage box, a battery, and a control component. The battery is installed inside the energy storage box, and the control component is used to control the charging and discharging operations of the battery. Since energy storage systems are existing technology, the specific components of the energy storage system will not be described in detail.
[0049] Existing energy storage boxes have ventilation holes on their side walls and install cooling components such as fans inside. The fans draw outside air into the box through these holes for air cooling. However, during this process, dust particles and other impurities can easily enter the box through these holes, leading to dust accumulation over time. This can cause safety risks such as battery short circuits, reducing the safety and reliability of the energy storage box.
[0050] To solve the above problems, such as Figures 1-5As shown, this embodiment also proposes an energy storage box. The energy storage device includes a box body 1, a ventilation mechanism 2, and an exhaust mechanism. The box body 1 has heat dissipation holes 11 and an air outlet 12. The ventilation mechanism 2 includes a drive component (not shown) and a heat dissipation window 21 movably mounted on the heat dissipation holes 11. The drive component is driven to the heat dissipation window 21 to open or close the heat dissipation holes 11. The exhaust mechanism includes a fan 3, a dust collection box 4, and a filter screen 5. The filter screen 5 is installed inside the dust collection box 4, which is connected to the air outlet 12. The fan 3 is configured to draw air from the box body 1 into the dust collection box 4, filter it through the filter screen 5, and then discharge it from the air outlet 12. The drive component of the ventilation mechanism 2 drives the heat dissipation window 21 to open the heat dissipation holes 11 of the box body 1, allowing external air to enter and exit the box body 1 through the heat dissipation holes 11, thereby removing heat from the box body 1 and achieving air cooling of the energy storage box. The exhaust fan 3 draws air from the housing 1 into the dust collection box 4 and exhausts it through the air outlet 12, further improving the air-cooling performance of the energy storage box. Simultaneously, dust particles and other impurities inside the housing 1 enter the dust collection box 4 with the air and are retained there by the filter screen 5. This achieves the filtration and collection of dust particles and other impurities, preventing dust accumulation inside the housing 1, reducing safety risks such as battery short circuits, and improving the safety and reliability of the energy storage box.
[0051] like Figure 1 and Figure 2 As shown, the front end of the enclosure 1 is open along the front-to-back direction. A cover is rotatably mounted on the enclosure 1, allowing it to be opened or closed. Multiple carrier plates 14 are installed inside the enclosure 1 along its height (vertical direction in the figure), supported by columns 15 to allow batteries to be placed on them. A temperature sensor 16 and a controller 17 are also installed inside the enclosure 1. Both the drive unit and the temperature sensor 16 are electrically connected to the controller 17. The temperature sensor 16 detects the temperature inside the enclosure 1 and transmits the temperature value to the controller 17. The controller 17 controls the drive unit to open or close based on the received temperature value. If the temperature sensor 16 detects that the temperature inside the enclosure 1 is higher than a specific value (which can be flexibly set according to actual operating conditions), the controller 17 controls the drive unit to open, thereby opening the ventilation holes 11 in the heat dissipation window 21, achieving air cooling of the enclosure 1.
[0052] In optional embodiments, such as Figure 2 As shown, both sides of the housing 1 along the left and right directions are provided with heat dissipation holes 11, and the two heat dissipation holes 11 are symmetrically arranged. When the two heat dissipation windows 21 open their corresponding heat dissipation holes 11, the outside air enters the housing 1 through the two heat dissipation holes 11 and carries away the heat inside the housing 1 (the air inside the housing 1 can be discharged from the two heat dissipation holes 11), thus achieving air cooling of the housing 1. In other embodiments, the number and installation position of the heat dissipation holes 11 can be flexibly adjusted according to the heat dissipation requirements, and are not specifically limited here.
[0053] It should be noted that a second dust filter 13 is provided on the outside of the housing 1, and the second dust filter 13 covers the heat dissipation hole 11. By providing the second dust filter 13, the air entering the housing 1 is filtered, reducing the amount of dust particles and other impurities entering the housing 1 through the heat dissipation hole 11, thereby improving the cleanliness of the air.
[0054] like Figure 3 and Figure 4 As shown, the heat dissipation window 21 includes a rotating shaft 211 and blades 212. Multiple rotating shafts 211 are arranged side-by-side along the height direction of the housing 1 within the heat dissipation hole 11. Each rotating shaft 211 is equipped with blades 212. A driving component is connected to the rotating shaft 211 to drive the rotating shaft 211 to rotate the corresponding blades 212 relative to the heat dissipation hole 11, thereby opening or closing the heat dissipation hole 11. This arrangement makes the heat dissipation window 21 a louver structure, allowing the heat dissipation hole 11 to be closed or opened through the synchronous rotation of multiple blades 212.
[0055] In an optional embodiment, pulleys 2110 are provided at both the first and second ends of the rotating shaft 211 along its axial direction. Among three adjacent rotating shafts 211, a transmission belt 213 is fitted between the pulley 2110 at the first end of the rotating shaft 211 located in the middle position and the pulley 2110 at the first end of the adjacent rotating shaft 211, and a transmission belt 213 is fitted between the pulley 2110 at the second end of the rotating shaft 211 located in the middle position and the pulley 2110 at the second end of the adjacent rotating shaft 211. The driving component is connected to one of the rotating shafts 211. The driving force of the driving component is transmitted through the transmission belt 213, resulting in a simple structure, low cost, and ease of installation and maintenance. Simultaneously, the transmission belt 213 operates smoothly and with low noise when transmitting driving force. Furthermore, along the height direction of the housing 1, multiple transmission belts 213 are staggered and distributed on the left and right sides of multiple rotating shafts 211 to achieve sequential transmission of driving force among the multiple rotating shafts 211, ensuring synchronous rotation of the multiple rotating shafts 211, thereby achieving synchronous flipping of the multiple blades 212.
[0056] like Figure 4 As shown, the driving component is a rotary motor. The output end of the rotary motor is connected to a first bevel gear 22 via a reducer. The first bevel gear 22 meshes with a second bevel gear 22. The gear shaft of the second bevel gear 22 is coaxially connected to the transmission shaft to drive the transmission shaft to rotate. The two meshing bevel gears 22 achieve power transmission between shafts that intersect at 90°, reducing the space occupied by the transmission components and achieving a compact arrangement of the ventilation mechanism 2.
[0057] like Figure 5 and Figure 6As shown, the dust collection box 4 includes a box body 41 and a box cover 42. The box body 41 has an installation hole 411 for the filter screen 5 to pass through. The filter screen 5 is detachably installed inside the box body 41, dividing the interior of the box body 41 into a first cavity and a second cavity. The fan 3 is configured to draw air from the box body 1 into the first cavity, and the second cavity is connected to the air outlet 12. One end of the box cover 42 is movably installed on the box body 41 and has an open position for opening the installation hole 411 and a closed position for closing the installation hole 411. The filter screen 5 divides the box body 41 into the first cavity and the second cavity, so that under the suction force of the fan 3, the air from the box body 1 is drawn into the first cavity, filtered by the filter screen 5, and then enters the second cavity. Finally, the air is discharged from the box body 1 through the air outlet 12. At the same time as the air is discharged, the air is filtered and dust is removed, so that dust particles and other impurities in the box body 1 are collected into the first cavity, avoiding the problem of dust accumulation in the box body 1.
[0058] like Figure 5 As shown, a mounting hole 411 is provided at the front end of the box body 41, and one end of the box cover 42 is pivotally mounted to the front end of the box body 41. Both the box cover 42 and the box body 41 are equipped with magnetic components 43. When the box cover 42 closes the mounting hole 411 of the box body 41, the magnetic components 43 of the box cover 42 and the box body 41 are attracted to each other, ensuring the airtightness of the box body 41 and preventing dust particles and other impurities collected in the first cavity from leaking out through the mounting hole 411. The box cover 42 can be opened manually, making operation simple and convenient for timely cleaning of dust particles and other impurities in the first cavity, and also facilitating quick replacement of the filter screen 5.
[0059] In an optional embodiment, a fan 3 is installed on both the left and right sides of the dust collection box 4 to increase the air circulation rate within the housing 1, thereby enhancing the air-cooling effect. In other embodiments, the number of fans 3 may be one or more.
[0060] It should be noted that in this embodiment, the dust collector box 4 is installed on the inner top wall of the housing 1 using fasteners such as screws. An air outlet 12 is provided at the top of the housing 1, and two heat dissipation holes 11 are located in the lower half of the housing 1. When the fan 3 is turned on, a cooling channel is formed inside the housing 1 from the heat dissipation holes 11 to the air outlet 12, allowing external air to enter the housing 1 through the heat dissipation holes 11 and then enter the dust collector box 4 from bottom to top along the height direction, thereby improving the ventilation and heat dissipation efficiency of the energy storage box.
[0061] like Figure 1 , Figure 5 and Figure 6As shown, the housing 41 is equipped with an air outlet 46. One end of the air outlet 46 is connected to the second cavity, and the other end is connected to the air outlet 12. In this embodiment, there are two air outlets 46, and two air outlets 12 are correspondingly opened at the top of the housing 1. The two air outlets 46 are respectively connected to the corresponding air outlets 12 to exhaust the air in the second cavity from the housing 1, thereby improving the air-cooling efficiency. In other embodiments, the number and size of the air outlets 46 can be flexibly adjusted according to the heat dissipation requirements.
[0062] In an optional embodiment, a first dustproof net 47 is provided at the other end of the air outlet duct 46. By providing the first dustproof net 47, external dust particles and other impurities can be prevented from entering the dust collection box 4 through the air outlet duct 46 after the fan 3 is turned off, thus preventing the air outlet duct 46 from becoming blocked and ensuring the normal use of the dust collection box 4.
[0063] like Figure 6 As shown, the dust collector box 4 also includes a limiting block 44 and a locking assembly 45. The limiting block 44 is disposed within the box body 41. The locking assembly 45 is disposed within the box body 41 and has a locking position and a releasing position. When the locking assembly 45 is in the locking position, the locking assembly 45 clamps the filter screen 5 with the limiting block 44. When the locking assembly 45 is in the releasing position, the locking assembly 45 disengages from the filter screen 5, allowing the filter screen 5 to separate from the box body 41. Through the cooperation of the locking assembly 45 and the limiting block 44, the filter screen 5 can be quickly installed and removed from the box body 41, facilitating the replacement and maintenance of the filter screen 5 and ensuring the dust removal effect.
[0064] In an optional embodiment, the top end of the filter screen 5 abuts against the inner top wall of the housing 41, and the bottom end of the filter screen 5 abuts against the inner bottom wall of the housing 41. The limiting block 44 and the locking assembly 45 are spaced apart along the front-rear direction on the inner bottom wall of the housing 41. When the filter screen 5 is assembled, the rear side of the bottom of the filter screen 5 abuts against the limiting block 44. When the locking assembly 45 is in the locked position, the front side of the bottom of the filter screen 5 contacts the locking assembly 45, so that the locking assembly 45 and the limiting block 44 clamp the filter screen 5. The locking assembly 45 is moved to the release position by external force (e.g., manual pressing) to release the limiting of the filter screen 5, allowing the filter screen 5 to be removed from the housing 41.
[0065] like Figure 6 and Figure 7As shown, the locking assembly 45 includes a base 451, a clamping block 452, and a resetting member 453. The base 451 is disposed on the housing 41. The clamping block 452 is slidably disposed on the base 451 and has a locked position and a released position. When the clamping block 452 slides to the locked position, it clamps the filter screen 5 with the limiting block 44. When the clamping block 452 slides to the released position, it disengages from the filter screen 5. The resetting member 453 is clamped between the base 451 and the clamping block 452, and the resetting member 453 is configured to ensure that the clamping block 452 always tends to slide to the locked position. The base 451 is fixedly installed on the housing 41 by welding or fasteners such as screws. Driven by the resetting member 453, the clamping block 452 can be stably held in the locked position so that the clamping block 452 and the limiting block 44 jointly clamp the filter screen 5.
[0066] By manually pressing the clamping block 452, the reset member 453 is pressed, and the clamping block 452 moves towards the base 451 to the release position. At this time, the clamping block 452 disengages from the filter screen 5, thereby releasing the restriction on the filter screen 5. The locking component 45 described above has a simple structure. By manually pressing, the clamping block 452 is moved from the locked position to the release position, and the reset member 453 returns the clamping block 452 from the release position to the locked position. The operation is simple and easy, improving the efficiency of filter screen 5 installation and removal.
[0067] In this embodiment, the reset component 453 is a spring. The spring has a simple structure and is easy to install and use. The base 451 is provided with a guide post, the spring is sleeved on the guide post, and one end of the clamping block 452 is sleeved on the guide post. One end of the spring is connected to the clamping block 452. Under the action of the elastic reset force of the spring, the clamping block 452 always remains in the locked position. When the clamping block 452 is compressed, it can compress the spring and move towards the base 451 until the clamping block 452 disengages from the filter screen 5, at which point the filter screen 5 can be removed.
[0068] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments.
