Description

Technical Field

[0001] This utility model relates to the field of energy battery technology, and in particular to a battery fire box. Background Technology

[0002] During the production process, due to improper design, manufacturing defects, or some external factors, batteries may overheat and release uncontrollable explosive electrical energy, producing smoke, flammable gases, and heat as high as 600℃~1000℃, which cannot be completely extinguished in a short time.

[0003] Currently, battery fire suppression methods primarily employ burying in sand and water spray cooling. Sand burying relies on suffocation, cooling the battery by isolating it from external oxygen. However, this method cannot prevent the chemical reactions of the positive and negative electrode materials inside the battery. Therefore, this method is time-consuming and has poor cooling effectiveness. Water spray cooling relies on a water pump and nozzles to create a high-pressure spray, expanding the spray area so that the water mist completely covers the battery and exchanges heat, achieving evaporative cooling. However, this method requires specialized spray equipment, which is complex, increasing both initial investment and subsequent maintenance costs. Utility Model Content

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0064] This application provides a battery fire-fighting box for fire-fighting cooling of batteries.

[0065] The following detailed description of specific embodiments of the battery fire extinguisher box of this application, in conjunction with the accompanying drawings, provides a comprehensive overview.

[0066] Figure 1 This is a schematic diagram of the battery fire extinguisher box in its first state in this embodiment. Figure 2 for Figure 1 A structural diagram of the battery-powered fire extinguisher box from another direction. Figure 3 This is a schematic diagram of the battery fire box in the second state in this embodiment.

[0067] refer to Figures 1-3 The battery fire extinguishing box includes a box body 1, a box cover 2, and at least one box door 3. The interior of the box body 1 is hollow, forming a cavity for accommodating batteries. The top of the box body 1 and at least one side along the circumference have openings communicating with the cavity. The box cover 2 is located at the top opening of the box body 1 and is hinged to the box body 1. The box cover 2 is used to open and close the top opening of the box body 1. Each opening along the circumference of the box body 1 is provided with one of the aforementioned box doors 3. The box doors 3 are rotatably connected to the box body 1 and are used to open and close the side openings of the box body 1. The box door 3 or the box body 1 is provided with a water inlet 35 and a drain outlet 16. The water inlet 35 is used to connect the cavity to an external coolant source, and the drain outlet 16 is used to discharge waste liquid from the cavity to the outside.

[0068] In this application, the opening on the body 1 of the battery fire extinguisher box allows batteries to enter and exit the accommodating cavity. In practical applications, the opening of the body 1 can be exposed by opening the cover 2 or the door 3 to facilitate the loading and unloading of batteries. In addition, the openable door 3 also allows waste inside the body 1 to be directly removed from the side opening of the body 1, facilitating waste disposal.

[0069] Furthermore, since the inlet 35 can connect the accommodating cavity and the external coolant source, coolant can be directly injected into the accommodating cavity through the inlet 35. The coolant can then irrigate and submerge the battery located in the accommodating cavity, thus continuously immersing the battery in liquid cooling. The coolant exchanges heat with the battery to directly remove the battery's heat, thereby achieving the purpose of rapid cooling of the battery. Moreover, this method does not require additional complex equipment, simplifying the structure of the battery fire box, and is easy and simple to operate, reducing costs.

[0070] In addition, the battery fire box in this application is also provided with a drain outlet 16, which allows the waste liquid in the containment cavity to be discharged outward through the drain outlet 16 after the battery cooling work is completed, so as to facilitate the centralized treatment of the waste liquid.

[0071] It should be noted that the first state of the battery fire extinguisher box in this article refers to the state when both the box cover 2 and the box door 3 are closed at the opening of the box body 1, and the second state of the battery fire extinguisher box refers to the state when the box cover 2 or the box door 3 is open and the opening of the box body 1 is exposed.

[0072] The coolant can be water. Alternatively, other liquids can also be used.

[0073] refer to Figures 1-3 The housing 1 has a hollow interior forming a cavity for accommodating the battery. The housing 1 also has an opening communicating with the cavity, which allows for the placement and removal of the battery. Exemplarily, the top of the housing 1 and at least one side along the circumference have openings communicating with the cavity. In practical applications, the battery can be placed into or removed from the cavity through any of these openings for ease of operation. Specifically, the top of the housing 1 and one side along the circumference have openings communicating with the cavity.

[0074] For ease of description, it is hereby defined that, with the battery fire box in its first state as the reference, the direction facing the inside of box 1 is defined as inside, and the direction away from the inside of box 1 is defined as outside.

[0075] Figure 4 This is a schematic diagram of the battery fire box in the third state in this embodiment.

[0076] It should be noted that the third state of the battery fire box in this article refers to the state when both the box cover 2 and the box door 3 are open.

[0077] refer to Figure 3 and Figure 4 The housing 1 includes a chassis 11 and three fixed walls 12. The three fixed walls 12 are arranged circumferentially on the chassis, and the three fixed walls 12 are connected in sequence and enclose the chassis 11 to form a receiving cavity with an opening at the top and one side of the circumference.

[0078] The chassis 11 includes a bottom frame 111 and a bottom plate 112. Specifically, the bottom frame 111 has a rectangular frame structure. The bottom plate 112 is fixed to the top of the bottom frame 111.

[0079] In this embodiment, the bottom frame 111 is provided with a slot 113 on its periphery. The slot 113 is used to cooperate with tools such as forklifts to realize the transfer of the battery fire box.

[0080] The fixed wall 12 includes a fixed plate 121 and a plurality of reinforcing beams 122. Specifically, the fixed plate 121 is erected on the chassis 11. The plurality of reinforcing beams 122 are arranged at intervals on the outer side of the fixed plate 121, thereby strengthening the fixed wall 12.

[0081] The fixed wall 12 is sealed to the chassis 11, which improves the sealing performance of the battery fire box.

[0082] The housing 1 also includes four uprights 13, which are arranged one-to-one with the four corners of the chassis 11, and the uprights 13 extend vertically. At this time, an upright 13 is arranged at each of the opposite ends of each fixed wall 12.

[0083] The box body 1 also includes multiple top beams 14, with one top beam 14 fixed to the top of each fixed wall 12, and each top beam 14 connected between two adjacent columns 13. At this time, each reinforcing beam 122 of the fixed wall 12 is also connected between the chassis 11 and the corresponding top beam 14, which can further enhance the structural strength of the fixed wall 12.

[0084] refer to Figures 1-3 The lid 2 is located on top of the box body 1 and is used to open and close the top opening of the box body 1.

[0085] The lid 2 is sealed to the body 1. Specifically, the inner side of the lid 2 is provided with a first sealing element 51. When the lid 2 is closed at the opening of the body 1, the first sealing element 51 is pressed and fitted to the body 1 to fill the gap between the lid 2 and the body 1, thereby achieving a sealed connection between the lid 2 and the body 1.

[0086] For example, the first sealing member 51 includes a first sealing portion and a second sealing portion that are in contact with each other, wherein an included angle is formed between the first sealing portion and the second sealing portion, the first sealing portion is connected to the cover 2, and the second sealing portion is used to press and fit against the box body 1. That is, the cross-section of the first sealing member 51 is V-shaped.

[0087] Figure 5 for Figure 3 Side view of the battery-operated fire extinguisher box along the AA direction. Figure 6 for Figure 1 A cross-sectional view of the battery fire extinguisher box along the BB direction.

[0088] refer to Figures 1-3 , Figure 5 and Figure 6 In this embodiment, the lid 2 includes a first lid body 21 and a second lid body 22, which are used to open and close the opening of the box 1 together. By dividing the lid 2 into two parts, the first lid body 21 and the second lid body 22, each part is lightweight and can be operated by one person, making operation convenient and simple, and saving manpower.

[0089] The first end of the first cover 21 is hinged to the housing 1, and the first cover 21 rotates outward to open a partial opening in the housing 1. Specifically, the first end of the first cover 21 is hinged to the outer side of a top beam 14, so that when the first cover 21 is closed, the inner side of the first end of the first cover 21 can fit against the top of the top beam 14. Exemplarily, the first cover 21 can be hinged to the housing 1 by means of a hinge, etc.

[0090] The first cover 21 is sealed to the box body 1. Specifically, the inner side of the first cover 21 is provided with a first sealing element 51 along the circumferential direction. When the first cover 21 is closed, the first sealing element 51 is pressed and fitted against the top beam 14 and the top of the box door 3.

[0091] Figure 7 for Figure 6 Enlarged structural diagram at point C.

[0092] refer to Figure 6 , Figure 7 The first cover 21 includes a support portion 2124, which is located at the second end of the first cover 21, and a support surface is formed on the support portion 2124.

[0093] The first cover 21 includes a frame 212 and a top plate 211. The frame 212 has a rectangular frame structure and includes four end-to-end support beams 2121. The top plate 211 covers the outer side and periphery of the frame 212. Optionally, a support surface is formed on the support beam 2121 located at the second end of the top plate 211. Specifically, the support beam 2121 includes a fixing part 2122, a connecting part 2123, and a support part 2124. The fixing part 2122 and the support part 2124 are located on the inner and outer sides of the connecting part 2123, and at opposite ends of the connecting part 2123. The fixing part 2122 is located at the first end of the connecting part 2123 and is fixed to the top plate 211. The support part 2124 is located at the second end of the connecting part 2123 and extends inward beyond the inner side of the remaining support beams 2121.

[0094] That is, in this embodiment, the support beam 2121 located at the second end of the top plate 211 is a Z-shaped beam.

[0095] In other embodiments, the support beam 2121 located at the second end of the top plate 211 can also be made of square steel tube, U-shaped beam, I-beam, etc., and a support plate can be fixed on the outside of the support beam 2121.

[0096] In this embodiment, the first end of the second cover 22 is hinged to the housing 1, and the first cover 21 and the second cover 22 rotate outward to open the opening of the housing 1. Specifically, the first end of the second cover 22 is hinged to the outer side of a top beam 14, so that when the second cover 22 is closed, the inner side of the first end of the second cover 22 can fit against the top of the top beam 14. Exemplarily, the second cover 22 can be hinged to the housing 1 by means of a hinge, etc.

[0097] The second cover 22 is sealed to the box body 1. Specifically, the inner side of the second cover 22 is provided with a first sealing element 51 along the circumferential direction. When the second cover 22 is closed, the first sealing element 51 is pressed and fitted against the top beam 14 and the top of the box door 3.

[0098] When the first cover 21 and the second cover 22 are closed at the top opening of the box 1, the second end of the first cover 21 overlaps with the second end of the second cover 22. Specifically, the inner side of the second end of the second cover 22 is in contact with the support surface. At this time, since the support part 2124 extends inward beyond the inner side of the remaining support beams 2121 of the frame 212 of the first cover 21, when the first cover 21 and the second cover 22 overlap and close at the opening of the box 1, the first cover 21 and the second cover 22 can be in the same plane, ensuring that the first end of the first cover 21 and the first end of the second cover 22 can fit with the corresponding top beam 14, thus ensuring the sealing performance of the battery fire box.

[0099] The support portion 2124 is sealed to the second cover 22. Specifically, a sealing gasket 53 is provided on the support surface of the support portion 2124, and the inner side of the second cover 22 is pressed against the sealing gasket 53 to compress the sealing gasket 53, thereby achieving a sealed connection between the support beam 2121 and the second cover 22.

[0100] Specifically, the structure of the second cover 22 is roughly the same as that of the first cover 21, both including a frame 212 and a top plate 211. It should be noted that the four supporting beams 2121 of the frame 212 of the second cover 22 are all made of square tubular steel.

[0101] refer to Figure 3 , Figure 4 and Figure 5 The battery fire extinguishing box also includes a lifting member 6, which is hinged between the inner side of the box body 1 and the inner side of the box cover 2. In this embodiment, there are two lifting members 6, which are arranged in a one-to-one correspondence with the first cover 21 and the second cover 22.

[0102] For example, the lifting member 6 includes a guide arm 61 and a free arm 62. A guide groove is formed on the guide arm 61, and the free arm 62 is at least partially located in the guide groove and slidably connected to the guide arm 61. Specifically, the guide arm 61 is hollow inside and open at one end to form the guide groove.

[0103] The guide arm 61 and the free arm 62 are sealed together. Specifically, the end of the free arm 62 located within the guide groove is provided with a sealing guide sleeve, the outer periphery of which fits tightly against the inner wall of the guide groove. Furthermore, a sealing ring is provided at the opening of the guide arm 61, and the sealing ring is fitted around the outer periphery of the free arm 62. That is, the sealing guide sleeve and the sealing ring fill the gap between the guide arm 61 and the free arm 62.

[0104] The outer diameter of the free arm 62 is smaller than the inner diameter of the guide arm 61, so that there is a gap between the free arm 62 and the guide arm 61. Under the sealing action of the sealing guide sleeve and the sealing ring, the sealing guide sleeve can divide the guide groove into two cavities. The cavity located on the side of the sealing guide sleeve away from the sealing ring is filled with compressed gas to increase the pressure in the cavity, so that there is a pressure difference between the two cavities.

[0105] The guide arm 61 is hinged to the inside of the cover 2, and the hinge is located at the end of the first cover 21 away from the door 3. The free arm 62 is hinged to the inside of the box 1, specifically to the upper part of the inside of a fixed wall 12, which is distributed opposite to the door 3.

[0106] In practical applications, the guide arm 61 and the free arm 62 can rotate with the rotation of the box cover 2, and the free arm 62 and the guide arm 61 can slide relative to each other to extend or shorten the length of the lifting member 6.

[0107] Specifically, when the lid 2 is closed at the opening of the box body 1, the length of the lifting member 6 is at its minimum. At this time, the pressure inside the cavity filled with compressed gas reaches its maximum due to the compression of space, increasing the pressure difference between the two cavities. During the process of pulling the lid 2 outward to open it, the pressure difference on both sides of the sealing guide sleeve of the lifting member 6 enables the movement of the sealing guide sleeve and the free arm 62, automatically extending the length of the lifting member 6. This assists in the rotation of the first cover 21 and the second cover 22, saving the external force applied when manually pulling to open the first cover 21 and the second cover 22, thus facilitating operation. In addition, after the first cover 21 and the second cover 22 are opened, the lifting member 6 can also adapt to support the first cover 21 and the second cover 22 to maintain the open state of the first cover 21 and the second cover 22.

[0108] In this embodiment, the lifting member 6 is a gas spring. However, this application is not limited to this; in other embodiments, the lifting member 6 may also be a hydraulic cylinder, a mechanical spring, etc.

[0109] The battery fire extinguishing box also includes a positioning element 71, which is hinged to the inside of the box cover 2 and can rotate relative to the box cover 2. The end of the positioning element 71 furthest from the box cover 2 is detachably connected to the box body 1. In practical applications, after the box cover 2 is opened, the positioning element 71 can be connected to the box body 1 to position and support the open box cover 2, further improving the stability of the open box cover 2. When it is necessary to close the box cover 2, the positioning element 71 can be easily and simply removed from the box body 1.

[0110] In this embodiment, there are two positioning members 71, and each positioning member 71 corresponds to one of the two lifting members 6. Optionally, the positioning member 71 and the first cover 21 can be hinged together by a hinge pin used for hinged connection between the lifting member 6 and the first cover 21. That is, one hinge pin simultaneously enables the hinge connection between the positioning member 71 and the first cover 21, and between the lifting member 6 and the box cover 2. The connection between the positioning member 71 and the second cover 22 adopts the above-described method.

[0111] Specifically, the positioning member 71 is provided with a snap-fit ​​part 711, and the fixed wall 12 of the housing 1 is provided with a retaining ring 72. The positioning member 71 and the housing 1 are connected by snapping the snap-fit ​​part 711 with the retaining ring 72. Optionally, multiple snap-fit ​​parts 711 can be provided on the positioning member 71 at intervals, so that one of the snap-fit ​​parts 711 can be selected to engage with the retaining ring 72 as needed to adjust the opening degree of the first cover 2 or the second cover 2 (relative to the rotation angle of the housing 1).

[0112] In this embodiment, both the first cover 21 and the second cover 22 are provided with pull rings 10. By pulling the pull rings 10, the first cover 21 or the second cover 22 can be rotated. That is, the pull rings 10 can be used as the force application point for the first cover 21 and the second cover 22 to facilitate operation by the operator.

[0113] refer to Figure 2 and Figure 4 The battery fire extinguishing box includes at least one door 3. A door 3 is provided at each opening along the circumference of the box body 1. The door 3 is rotatably connected to the box body 1 and is used to open and close the side openings of the box body 1. Specifically, there is one door 3. In other embodiments, there may be multiple doors 3, as long as the doors 3 are sequentially connected end-to-end to the fixed wall 12 and can be enclosed with the chassis 11 to form a top opening.

[0114] The first end of the door 3 is hinged to the box body 1, so that the door 3 can rotate outward or inward relative to the box body 1 with the hinge as the rotation center, so as to open or close the side opening of the box body 1.

[0115] In this embodiment, the battery fire extinguisher box includes at least two rotating components 20, and each box door 3 is rotatably connected to the box body 1 through at least two rotating components 20.

[0116] Figure 8 This is a partial structural diagram of the battery fire box in this embodiment.

[0117] refer to Figure 8 For example, each rotating component 20 includes a first hinge seat 201, a second hinge seat 202, a first hinge block 203, and a second hinge block 204. The first hinge seat 201 is located at the side opening end of the housing 1. The second hinge seat 202 is located at the end of the door 3. The first hinge block 203 is hinged to the first hinge seat 201. The two opposite ends of the second hinge block 204 are respectively hinged to the second hinge seat 202 and the first hinge block 203. The first hinge seat 201, the second hinge seat 202, the first hinge block 203, and the second hinge block 204 are used together to realize the rotation of the door 3 relative to the housing 1 in the horizontal plane.

[0118] Specifically, the first hinge seat 201 and the first hinge block 203 are hinged together by the first hinge shaft 205, the first hinge block 203 and the second hinge block 204 are hinged together by the second hinge shaft 206, and the second hinge block 204 and the second hinge seat 202 are hinged together by the third hinge shaft 207. The first hinge shaft 205, the second hinge shaft and the third hinge shaft 207 are parallel to each other.

[0119] In other words, this application uses a three-axis rotating assembly 20 to achieve a rotatable connection between the door 3 and the body 1. Compared to using a two-axis or one-axis assembly, which has disadvantages such as a very fixed motion trajectory and poor adjustability, in the three-axis rotating assembly 20 used in this application, the first hinge seat 201 and the first hinge block 203 can rotate relative to each other independently of other components, the first hinge block 203 and the second hinge block 204 can rotate relative to each other independently of other components, and the second hinge block 204 and the second hinge seat 202 can also rotate relative to each other independently of other components. This allows for rotation between the first hinge seat 201 and the first hinge block 203, between the first hinge block 203 and the second hinge block 204, and between the second hinge block 204 and the second hinge seat 202. The relative angles of the two second hinge seats 202 can be adjusted separately. The rotation component 20 can increase the range of rotation angles of the door 3 relative to the box body 1, thereby increasing the direction of rotation adjustment of the door 3 through the rotation component 20. Furthermore, through the above-mentioned angle adjustment, the door 3 can also be extended and translated in the direction perpendicular to the first hinge axis 205, so that the door 3 moves closer to or away from the box body 1, thereby adjusting the relative position between the door 3 and the box body 1, improving the adjustability of the door 3, so that the inner side of the door 3 is tightly attached to the side opening end of the box body 1, thereby improving the sealing performance of the fire battery box.

[0120] The first hinge seat 201 has a first groove on the side away from the housing 1, one end of the first hinge block 203 is accommodated in the first groove, and the first hinge shaft 205 passes through the ends of the first hinge seat 201 and the first hinge block 203 located in the first groove to realize the hinge of the first hinge seat 201 and the first hinge block 203.

[0121] The second hinge block 204 has a second groove at one end, and the end of the first hinge block 203 facing away from the first hinge seat 201 is accommodated in the second groove. The second hinge shaft 206 passes through the ends of the second hinge block 204 and the first hinge block 203 located in the second groove, so as to realize the hinge of the first hinge seat 201 and the second hinge block 204.

[0122] The second hinge seat 202 is provided with a third groove. One end of the second hinge block 204 away from the first hinge block 203 is accommodated in the third groove. The third hinge shaft 207 passes through the ends of the second hinge seat 202 and the second hinge block 204 located in the third groove, so as to realize the hinge of the second hinge seat 202 and the second hinge block 204.

[0123] In this embodiment, the door 3 is detachably connected to the body 1 to facilitate locking and unlocking between the door 3 and the body 1. Optionally, the battery fire extinguisher box further includes at least one locking assembly 8, through which the second end of the door 3 is detachably connected to the body 1. In this case, the first end of the door 3 is hinged to one of the uprights 13 located at the opening end of the body 1, and the second end of the door 3 is detachably connected to another upright 13 located at the opening end of the body 1. Here, the second end refers to the end opposite to the first end of the door 3.

[0124] refer to Figure 2 The upper and lower ends and the first end of the door 3 can also be detachably connected to the box body 1 by at least one locking component 8 to increase the connection strength between the door 3 and the box body 1.

[0125] refer to Figure 8 Each locking assembly 8 includes a locking member 81 and a pressing member 82. Specifically, the locking member 81 is rotatably disposed at the side opening end of the housing 1, and the locking member 81 can rotate relative to the housing 1. The pressing member 82 is disposed at the edge of the door 3 and protrudes outward from the door 3. The pressing member 82 is provided with an outwardly opening snap-fit ​​interface 821, which is used to snap-fit ​​with the locking member 81, thereby realizing a detachable connection between the door 3 and the housing 1.

[0126] The locking assembly 8 further includes a connecting base 84 and a pin 85. The connecting base 84 is fixed to the column 13 of the housing 1, and a receiving groove is formed on the connecting base 84 to accommodate the end of the locking member 81. The pin 85 passes vertically through the connecting base 84 and the locking member 81 to achieve a rotatable connection between the locking member 81 and the connecting base 84.

[0127] The locking assembly 8 also includes a locking member 83, which is movably connected to the end of the locking member 81 away from the housing 1. When the locking member 81 engages with the card slot 821, the locking member 83 is located outside the pressing member 82. The outer diameter of the locking member 83 is larger than the diameter of the card slot 821. Because the locking member 83 can move relative to the locking member 81, it can move towards the housing door 3 to abut against the pressing member 82, thereby pressing the pressing member 82 against the housing 1 to lock the housing door 3.

[0128] Furthermore, since the rotating assembly 20 can move the door 3 closer to or further away from the box body 1, during the process of closing the door 3 at the side opening of the box body 1, the gap between the inner side of the door 3 and the side opening of the box body 1 can be adjusted by rotating the assembly 20. Then, the locking member 83 of the locking assembly 8 can be moved relative to the locking member 81 to adapt to the door 3 after the gap has been adjusted. That is, the locking assembly 8 and the rotating assembly 20 can cooperate to make the locking force of the door 3 adjustable, thereby ensuring that the door 3 can be pressed against the side opening of the box body 1 when closed, so as to improve the sealing performance of the battery fire box.

[0129] Similarly, in the above design, the locking member 83 can also move away from the door 3 and have a gap between it and the pressing member 82, so as to rotate the locking member 81 to release the engagement between the locking member 81 and the pressing member 82, thereby unlocking the door 3. The above operation is convenient and simple, can be performed by one person, and can quickly unlock and lock the door 3.

[0130] For example, the outer periphery of the locking member 81 is provided with an external thread, the locking member 83 is provided with a locking groove, and the inner peripheral wall of the locking groove is provided with an internal thread adapted to the external thread. The internal thread and the external thread are screwed together to realize the movable connection between the locking member 81 and the locking member 83.

[0131] The locking assembly 8 may further include a washer 86, which is sleeved on the outer periphery of the crimping member 82 and located between the locking member 83 and the connecting base 84. When the locking member 81 engages with the snap-fit ​​interface 821, the washer 86 is located on the outside of the crimping member 82. The outer diameter of the washer 86 is larger than the outer diameter of the locking member 83, and the outer diameter of the washer 86 is larger than the opening diameter of the snap-fit ​​interface 821. In practical applications, as the locking member 83 moves toward the door 3, the locking member 83 can abut against the washer 86, and the washer 86 abuts against the outside of the crimping member 82. This increases the contact area with the crimping member 82 and improves the locking effect on the door 3.

[0132] In this embodiment, there can be multiple locking components 8, which are distributed at intervals along the circumference of the door 3. This allows the door 3 to be locked in the circumference, improving the locking effect of the door 3 and reducing the gap between the door 3 and the box body 1 in the circumference, thereby improving the sealing performance of the battery fire box.

[0133] The door 3 is sealed to the body 1, which improves the sealing performance of the battery fire extinguisher box. (Reference) Figure 4 For example, the inner side of the door 3 is provided with a second sealing member 52. When the door 3 is closed at the opening of the box body 1, the second sealing member 52 is pressed and fitted with the box body 1 to fill the gap between the door 3 and the box body 1, thereby achieving a sealed connection between the door 3 and the box body 1.

[0134] Exemplarily, the door 3 includes a frame 32 and a panel 31. The frame 32 has a rectangular frame structure. The panel 31 is fixed to the inner side of the frame 32. The door 3 may also include multiple reinforcing beams 33, which are spaced apart on the outer periphery of the panel 31 to enhance the structural strength of the door 3. Each reinforcing beam 33 extends vertically, and its upper and lower ends are connected to the frame 32. Adjacent reinforcing beams 33 can also be connected by at least one connecting beam 34. The reinforcing beams 33 located at the edges can also be connected to the frame 32 by at least one connecting beam 34, and each connecting beam 34 is connected to the outer side of the panel 31, thereby further enhancing the structural strength of the door 3.

[0135] refer to Figures 1-5 The door 3 or the body 1 is provided with a water inlet 35 and a drain outlet 16. The water inlet 35 is used to connect the accommodating cavity and the external coolant source, and the drain outlet 16 is used to discharge the waste liquid in the accommodating cavity to the outside.

[0136] refer to Figure 2 , Figure 4 The inlet 35 is specifically located at the top of the door 3, which allows the liquid to flow from top to bottom inside the housing 1 to gradually fill the cavity. Compared with the bottom liquid inlet method, the top liquid inlet method in this application can avoid the hydraulic pressure of the coolant already stored inside the housing 1 affecting the liquid outlet of the inlet 35, so as to ensure the smoothness and stability of the liquid flow from the inlet 35 into the housing 1.

[0137] In this embodiment, a first connecting connector 41 is connected to the water inlet 35. The first connecting connector 41 is used for detachable connection with an external coolant supply device, which facilitates quick connection and disconnection between the battery fire box and the external coolant supply device, making operation convenient and simple. For example, the first connecting connector 41 is a fire hose connector.

[0138] The drain outlet 16 is specifically located at the bottom of the housing 1, which facilitates the complete discharge of waste liquid in the containment cavity and improves the waste discharge effect.

[0139] Figure 9 for Figure 3 Enlarged structural diagram at point D.

[0140] refer to Figure 9 In this embodiment, a second connecting joint 42 is provided at the drain outlet 16. The second connecting joint 42 is used for detachable connection with an external waste liquid collection device, which facilitates quick connection and disconnection between the battery fire extinguisher box and the external waste liquid collection device, making operation convenient and simple. A valve 43 is provided on the second connecting joint 42 to control the opening and closing of the drain outlet 16. For example, the second connecting joint 42 is a fire extinguisher connector.

[0141] Figure 10 for Figure 3 Enlarged structural diagram at point E in the middle.

[0142] refer to Figure 3 , Figure 4 and Figure 10 Multiple support beams 17 are spaced apart on the bottom wall inside the housing 1. These beams collectively support the battery and position it above the bottom wall of the housing 1. In practical applications, the space between the battery and the bottom wall of the housing 1 can accommodate coolant, allowing the coolant to contact the bottom of the battery. This increases the contact area between the battery and the coolant, ensuring the battery is completely submerged in the coolant for rapid cooling and improved efficiency. Furthermore, the support beams 17 prevent damage to the bottom wall of the housing 1 from excessive force during battery insertion, thus protecting the housing 1. Specifically, the support beams 17 are spaced apart on the top of the base plate 112. Optionally, each support beam 17 is arranged parallel to and spaced apart from the water inlet 35.

[0143] In this embodiment, each supporting beam 17 is provided with a through hole 171 for the flow of liquid within the accommodating cavity. In practical applications, during the injection of coolant into the accommodating cavity, the coolant can quickly and evenly fill the gap between adjacent supporting beams 17 through the through hole 171. When discharging waste liquid, the waste liquid can also gradually flow towards the drain outlet 16 through the through hole 171, thus further ensuring that the waste liquid within the accommodating cavity can be completely discharged.

[0144] Each supporting beam 17 can have one through hole 171. Optionally, the through holes 171 on each supporting beam 17 are arranged aligned with the water inlet 35, so that the waste liquid flowing through the through holes 171 can flow directly to the drain outlet 16, which can improve the efficiency of liquid flow to a certain extent.

[0145] In other embodiments, multiple through holes 171 may be provided at intervals on each supporting beam 17 to improve the efficiency of liquid flow.

[0146] In this embodiment, each load-bearing beam 17 has a concave surface on one side. That is, the cross-section of the load-bearing beam 17 is C-shaped, which allows the load-bearing beam 17 to effectively distribute the load, reduce stress concentration, and improve the load-bearing capacity of the load-bearing beam 17. Specifically, the opening direction of the concave surface of each load-bearing beam 17 is consistent.

[0147] refer to Figure 2 In this embodiment, the battery fire box also includes at least one support component 9, and at least one support component 9 is provided on the outer side of the second end of each box door 3.

[0148] Figure 11 This is a schematic diagram of the structure of the support component 9 in this embodiment.

[0149] refer to Figure 11 The support assembly 9 includes a connecting rod 91 and a support wheel 92. The connecting rod 91 is connected to the door 3, and the support wheel 92 is rotatably connected to the bottom of the connecting rod 91. The support wheel 92 extends downward beyond the bottom of the door 3. The support wheel 92 can roll along the outer bearing surface as the door 3 rotates, thus providing support and traction for the opening and closing of the door 3, assisting the door 3 in rotating during the opening and closing process, saving the external force applied when manually pulling to open the door 3, and making operation more convenient.

[0150] The external bearing surface mentioned above can be the ground or any other plane.

[0151] Optionally, the support assembly 9 may further include a first positioning frame 93, a second positioning frame 94, and a screw 95. The first positioning frame 93 and the second positioning frame 94 are vertically spaced on the door 3. The screw 95 passes vertically through the first positioning frame 93. The connecting rod 91 passes vertically through the second positioning frame 94. The screw 95 is threadedly connected to the first positioning frame 93, and the connecting rod 91 is slidably connected to the second positioning frame 94. The top of the connecting rod 91 abuts against or is fixed to the bottom of the screw 95. The screw 95 can rotate relative to the first positioning frame 93 and move vertically up and down relative to the first positioning frame 93 to adjust the vertical position of the support wheel 92.

[0152] The above design allows for adjustable position of the support wheel 92, enabling it to better adapt to the external bearing surface and improving its auxiliary rotation and support functions. Furthermore, the adjustable height of the support wheel 92 also assists in supporting the second end of the door 3 after height adjustment, ensuring the door 3 is completely closed at the side opening of the box body 1 and that the side of the second seal 52 facing away from the door 3 is fully pressed against the side opening of the box body 1, thus improving the sealing effect of the battery fire extinguisher box. Simultaneously, after the door 3 is locked to the box body 1 by the locking assembly 8, the height of the support wheel 92 can be adjusted to lift it upwards and remove it from the bearing surface, preventing damage from prolonged contact and extending its service life.

[0153] It should be noted that the axis of the connecting rod 91 is arranged parallel to the axis of the screw 95, so that the screw 95 can accurately act on the connecting rod 91, ensuring the transmission effect between the two and improving the structural reliability. In the actual installation process, the axes of the screw 95 and the connecting rod 91 can be slightly offset, as long as the screw 95 can connect or abut with the connecting rod 91.

[0154] In other embodiments, the screw 95 is rotatably connected to the first positioning frame 93, the connecting rod 91 is slidably connected to the second positioning frame 94, and the screw 95 is screwed to the connecting rod 91. The screw 95 can rotate relative to the first positioning frame 93 and the connecting rod 91, so that the connecting rod 91 drives the support wheel 92 to rise and fall vertically. The height adjustment of the support wheel 92 can also be achieved in other forms (e.g., a telescopic rod), depending on the specific needs, and no further restrictions are imposed here.

[0155] In this embodiment, the first positioning frame 93 can be a plate. The second positioning frame 94 can be composed of at least one plate. Specifically, the second positioning frame 94 includes two positioning plates 941 arranged vertically at intervals, and the connecting rod 91 passes through both positioning plates 941 simultaneously. In other embodiments, the first positioning frame 93 and the second positioning frame 94 can also be structures such as sleeves.

[0156] Optionally, the support assembly 9 may further include a reset member 96, which is sleeved on the outer periphery of the connecting rod 91. One end of the reset member 96 is connected to one of the positioning plates 941, and the other end is connected to the connecting rod 91 to limit the position of the reset member 96 on the connecting rod 91. The opposite ends of the reset member 96 can move closer to or further away from each other as the connecting rod 91 rises and falls.

[0157] Specifically, the reset element 96 can be a compression spring. That is, the top end of the reset element 96 is connected to the connecting rod 91, and the bottom end of the reset element 96 is connected to the top of the positioning plate 941 located below, and the reset element 96 is in a compressed state. At this time, the reset element 96 continuously applies an upward thrust to the connecting rod 91 in order to restore its deformation. This makes the connecting rod 91 always abut against the bottom end of the screw 95, so that the connecting rod 91 can slide up and down normally with the position adjustment of the screw 95 to achieve lifting and lowering.

[0158] In other embodiments, the reset member 96 can also be a tension spring. That is, the top end of the reset member 96 is connected to the bottom of the positioning plate 941 located above, the bottom end of the reset member 96 is connected to the connecting rod 91, and the reset member 96 is in a stretched state. At this time, the reset member 96 continuously applies an upward pulling force to the connecting rod 91 in order to restore its deformation. This makes the connecting rod 91 always abut against the bottom end of the screw 95, so that the connecting rod 91 can slide up and down normally with the position adjustment of the screw 95 to achieve lifting and lowering.

[0159] The support assembly 9 may further include a limiting member 97, which is disposed on the outer periphery of the connecting rod 91 and is used to connect with the reset member 96. The reset member 96 may abut against and be limited between the limiting member 97 and the positioning plate 941, or it may be fixed between the limiting member 97 and the positioning plate 941. The limiting member 97 may be annular, or it may be composed of multiple limiting bodies arranged at intervals along the circumference of the connecting rod 91, in which case the multiple limiting bodies work together to abut against or connect to the reset member 96.

[0160] Optionally, the support assembly 9 may also include a rotating handle 98, which is fixed to the top of the screw 95. An external force can be applied to the rotating handle 98 to drive the screw 95 to rotate relative to the first positioning frame 93 for easy operation.

[0161] Based on the above description, it is evident that the battery fire box provided in this application has a structure that facilitates operation, is simple and quick to use, and can be operated by one person, saving manpower and being safe and environmentally friendly.

[0162] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0163] In this application, the opening on the battery fire extinguisher box allows batteries to enter and exit the containment chamber. In practical applications, the opening can be exposed by opening the box cover or door to facilitate battery loading and unloading. Furthermore, the openable door allows waste materials inside the box to be removed directly from the side opening, facilitating waste disposal.

[0164] Furthermore, since the water inlet on the enclosure can connect the housing cavity to the external coolant source, coolant can be directly injected into the housing cavity through the water inlet. The coolant can then irrigate and submerge the battery located in the housing cavity, thus providing continuous immersion liquid cooling for the battery. The coolant exchanges heat with the battery to directly remove the battery's heat, thereby achieving the purpose of rapid cooling of the battery. Moreover, this method does not require additional complex equipment, simplifying the structure of the battery fire box, and is convenient and simple to operate, reducing costs.

[0165] In addition, the battery fire box in this application is also equipped with a drain outlet, which allows the waste liquid in the containment cavity to be discharged outward after the battery cooling work is completed, so as to facilitate the centralized treatment of the waste liquid.

[0166] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
