[0001] This application relates to the field of battery technology, and more particularly to a fireproof door and a box-type power supply. Background Technology

[0002] As an energy storage device, a box-type power supply can be used as a power unit, energy storage device, etc. Box-type power supplies are large in size and contain many battery modules, making them weigh several tons or even tens of tons. They are equipped with fire doors to improve safety. Box-type power supplies are generally moved by hoisting; if the fire doors are not strong enough, they are prone to bending and deformation after hoisting. Utility Model Content

[0003] This application provides a fire door and a box-type power supply.

[0004] The fire door of this application includes a door frame and a door body, the door body and the door frame being rotatably connected, the door body including a first door panel and a second door panel disposed opposite to each other, a reinforcing member and filler, the reinforcing member being disposed between the first door panel and the second door panel; at least part of the filler is filled between the first door panel and the second door panel and surrounds the reinforcing member.

[0005] In the fire door of this application embodiment, at least part of the filler is filled between the first door panel and the second door panel and surrounds the reinforcing member, so that the door body can be formed as a whole. The filler and the reinforcing member work together to strengthen the door body. After the fire door is hoisted, the risk of the fire door bending is reduced.

[0006] In some embodiments, the door body further includes a fireproof plate located between the first door panel and the second door panel and disposed on the first door panel, and the reinforcing member connects the fireproof plate and the second door panel.

[0007] In this way, fireproof boards can not only improve the fire resistance of fire doors, but also further enhance the strength of the door body.

[0008] In some embodiments, the reinforcing member has an I-shaped cross-section and includes a first connecting portion, a second connecting portion, and a third connecting portion connected in sequence. The widths of the first connecting portion and the third connecting portion are both greater than the width of the second connecting portion. The first connecting portion is connected to the second door panel, and the third connecting portion is connected to the fireproof board.

[0009] In this way, the I-shaped reinforcing members have strong bending resistance, which can improve the strength of the door.

[0010] In some embodiments, the reinforcing members extend from the top to the bottom of the door body, and there are multiple reinforcing members arranged at intervals along the width direction of the door body. This arrangement of multiple reinforcing members at intervals along the width direction of the door body strengthens the door body at various locations, comprehensively improving its overall strength.

[0011] In some embodiments, there are two doors, with the side of the two doors furthest from each other rotatably connected to the door frame. Each door is equipped with a lock, which locks or unlocks the side of the two doors closest to each other.

[0012] Thus, the door is designed as a double door structure, and the door lock locks or unlocks the two doors on the side that is close to each other, making it convenient for the fire door to open or close.

[0013] In some embodiments, the door lock has a keyhole and a cover that is movable relative to the door lock to cover or open the keyhole. Thus, by covering the keyhole, the cover reduces the entry of foreign objects, allowing the door lock to function normally and extending its lifespan.

[0014] In some embodiments, the door lock or the door body is provided with a door handle, which is detachably connected to the door lock or the door body. This allows the door handle to facilitate opening and closing of the door. Furthermore, the detachable connection of the door handle to the door lock or the door body allows it to be removed when not in use, preventing interference such as collisions with external objects and improving the ease of use of the fire door.

[0015] In some embodiments, a first seal is provided on the side of the two doors that are close to each other, and the first seal seals the gap between the two doors on the side that are close to each other. In this way, the first seal can reduce the passage of foreign objects such as liquids through the fire door from the side of the two doors that are close to each other, thereby improving the sealing performance of the fire door.

[0016] In some embodiments, the door body further includes a sealing plate disposed on the side of the first door panel and the second door panel near the door frame, and a second sealing member is provided between the sealing plate and the door frame to seal the gap between the sealing plate and the door frame. Thus, the second sealing member can seal the gap between the door body and the door frame, thereby reducing the passage of liquids or other foreign objects through the gap between the door body and the door frame into the fire door, and improving the sealing performance of the fire door.

[0017] In some embodiments, at least a portion of the outer surfaces of the door frame and the door body are coated with an anti-corrosion layer. This anti-corrosion layer improves the corrosion resistance of the fire door, thereby extending its lifespan.

[0018] In some embodiments, the fireproof board has a flexural strength ≥10 MPa. This high flexural strength improves the door's resistance to bending, making it less prone to deformation.

[0019] In some embodiments, the fireproof board comprises a calcium silicate board. Thus, the fireproof board has good fire resistance and high strength, improving both its fire resistance and flexural strength.

[0020] In some embodiments, the filler is a biodegradable filler. This allows the filler to decompose easily, improving the environmental performance of the fire door.

[0021] In some embodiments, the fire door includes a latch mounted on the door body, the latch being detachably engaged with the top and / or bottom of the door frame. This allows the door to remain closed under the action of the latch, improving the stability of the door when closed.

[0022] The box-type power supply in this application includes the fire door described in any of the above embodiments.

[0029] Please see Figures 1-3 The fire door 100 of this application includes a door frame 10 and a door body 20. The door body 20 is rotatably connected to the door frame 10. The door body 20 includes a first door panel 21, a second door panel 22, a reinforcing member 24, and a filler 25. The first door panel 21 and the second door panel 22 are arranged opposite to each other. The reinforcing member 24 is disposed between the first door panel 21 and the second door panel 22. At least part of the filler 25 is between the first door panel 21 and the second door panel 22 and surrounds the reinforcing member 24.

[0030] Fire door 100 can be used in box-type power supplies, or in other words, box-type power supplies include fire door 100. Box-type power supplies, such as energy storage cabinets, have internal components that easily generate heat and are susceptible to temperature fluctuations. Therefore, fire door 100 can prevent external fire from entering the box-type power supply, improving its safety.

[0031] The box-type power supply can be placed on a ship for transport to its destination. Understandably, due to its considerable weight, it typically requires hoisting for movement. Therefore, the flexural strength of the box-type power supply is extremely important, especially against fire doors of grade 100.

[0032] In the fire door 100 of this application embodiment, at least part of the filler 25 is between the first door panel 21 and the second door panel 22 and surrounds the reinforcing member 24, so that the door body 20 can be formed as a whole. The filler 25 and the reinforcing member 24 work together to strengthen the strength of the door body 20. After hoisting, the risk of the fire door 100 bending is reduced by using the box-type power supply of the fire door 100.

[0033] Specifically, the door frame 10 is a structure used to install the door body 20. The door frame 10 can be formed by bending sheet metal. To improve the strength of the door frame 10, it includes square tubes located inside the door frame 10. In one example, the sheet metal and square tubes of the door frame 10 can be made of steel to improve the strength of the door frame 10 and effectively resist lateral or vertical loads. For example, the material of the sheet metal and square tubes of the door frame 10 is Q235B.

[0034] In one example, the square tube is 6mm thick and contains filler 25 to enhance the strength of the door frame 10.

[0035] like Figure 1 As shown, the door body 20 can be rotatably connected to the door frame 10 via hinges 30. To improve the corrosion resistance of the hinges 30, they can be made of SUS316L material. The first door panel 21 and the second door panel 22 are the panels on both sides of the door body 20 in the thickness direction, forming the maximum surface of the door body 20. The first door panel 21 and the second door panel 22 can be made of steel to improve the strength of the door panels. For example, the steel used for the first door panel 21 and the second door panel 22 is Q235B steel.

[0036] The first door panel 21 can be the outer panel of the door body 20, and the second door panel 22 can be the inner panel of the door body 20. Alternatively, the first door panel 21 can face the outer side of the fire door 100, and the second door panel 22 can face the inner side of the fire door 100.

[0037] The reinforcing member 24 can improve the strength of the door body 20, and the reinforcing member 24 can be fixed to the second door panel 22 by welding.

[0038] The filler 25 is generally made of lightweight material, such as fire-resistant filler. The filler 25 can improve the fire resistance of the fire door 100 on the one hand, and reduce the weight of the fire door 100 on the other hand, which is beneficial for the opening and closing of the door 20.

[0039] In one example, the fire door 100 can meet the average daily hoisting requirement of the box-type power supply and has a strong resistance to bending moment loads.

[0040] Please see Figures 1-3 In some embodiments, the door body 20 further includes a fireproof plate 23, which is located between the first door panel 21 and the second door panel 22 and is disposed on the first door panel 21. The reinforcing member 24 connects the fireproof plate 23 and the second door panel 22. In this way, the fireproof plate 23 can not only improve the fireproof effect of the fire door 100, but also further improve the strength of the door body 20.

[0041] Specifically, the fireproof board 23 is a fire-resistant board material. The fireproof board 23 can be fixed to the first door panel 21 by means of adhesive or other methods. The fireproof board 23 not only provides fire protection but also increases the strength of the door body 20.

[0042] Please see Figure 3 In some embodiments, the cross-section of the reinforcing member 24 is I-shaped and includes a first connecting portion 241, a second connecting portion 242 and a third connecting portion 243 connected in sequence. The widths of the first connecting portion 241 and the third connecting portion 243 are both greater than the width of the second connecting portion 242. The first connecting portion 241 is connected to the second door panel 22 and the third connecting portion 243 is connected to the fireproof board 23.

[0043] Thus, the I-beam-shaped reinforcing member 24 has strong bending resistance, which can improve the strength of the door body 20. Specifically, the reinforcing member 24 is elongated. The first connecting part 241, the second connecting part 242, and the third connecting part 243 are integrally formed structures. The reinforcing member 24 can be an I-beam, for example, the material of the reinforcing member 24 is Q355B steel. The first connecting part 241, the second connecting part 242, and the third connecting part 243 can be connected to form an I-beam shape.

[0044] In one example, during the transportation of the box-type power supply, the reinforcement 24 enables the fire door 100 to withstand external loads greater than 10KN / ㎡, and when installed on the deck, it effectively resists the frontal impact and external force impact from the waves.

[0045] Please see Figure 3In some embodiments, the reinforcing members 24 extend from the top to the bottom of the door body 20, and there are multiple reinforcing members 24 arranged at intervals along the width direction of the door body 20. For example, the number of reinforcing members 24 may be 3, 4, 5, 6, etc. In this way, the multiple reinforcing members 24 are arranged at intervals along the width direction of the door body 20 and extend from the top to the bottom of the door body 20, which can strengthen the strength of the door body 20 at all locations and comprehensively improve the strength of the door body 20.

[0046] In one example, there are 5 reinforcing members 24 on each door body 20, and the spacing between two adjacent reinforcing members 24 is 200mm.

[0047] Please see Figure 1 and Figure 2 In some embodiments, there are two door bodies 20. The side of the two door bodies 20 that is far apart from each other is rotatably connected to the door frame 10. The door body 20 is provided with a door lock 261, which locks or unlocks the side of the two door bodies 20 that is close to each other.

[0048] Thus, the door 20 is configured as a double door structure, and the door lock 261 locks or unlocks the two door bodies 20 on the side that is close to each other, making it convenient for the fire door 100 to open or close.

[0049] Specifically, each door body 20 is connected to the door frame 10 via multiple hinges 30, and each door body 20 can rotate 180° relative to the door frame 10. The door lock 261 can be locked or unlocked by a key. In one example, the door lock 261 can be opened from the outside of the door body 20 using a key, thereby allowing the door body 20 to rotate.

[0050] Please see Figure 1 and Figure 2 In some embodiments, the door lock 261 has a keyhole and a cover 262 that is movable relative to the door lock 261 to cover or open the keyhole. Thus, by covering the keyhole, the cover 262 reduces the entry of foreign objects into the keyhole, allowing the door lock 261 to function normally and extending its lifespan.

[0051] Specifically, during the use or transportation of the box-type power supply, liquids (such as seawater) may enter the keyhole and corrode the door lock 261, preventing it from opening properly. Therefore, the shield 262 can prevent liquid from entering the keyhole, reducing the risk of corrosion to the door lock 261.

[0052] In one example, the obstruction 262 is, for instance, a cover, which is detachably mounted on the door lock 261. The cover protrudes from the outer surface of the first door panel 21. When it is necessary to open the keyhole, the obstruction 262 can be pried open using an object such as a key, allowing the key to be inserted into the keyhole.

[0053] Please see Figures 1-3 In some embodiments, a door handle 263 is provided on the door lock 261 or the door body 20, and the door handle 263 is detachably connected to the door lock 261 or the door body 20. In this way, the door handle 263 can facilitate the opening and closing of the door body 20. In addition, the detachable connection between the door handle 263 and the door lock 261 or the door body 20 allows the door handle 263 to be removed when not in use, avoiding interference such as collisions between the door handle 263 and external objects, and improving the ease of use of the fire door 100.

[0054] Specifically, the door handle 263 is bent, allowing the door 20 to be opened after the key is inserted into the lock. In one example, with the door 20 closed, removing the door handle 263 ensures that it will not interfere with adjacent power supply units if multiple box-type power supplies are arranged side-by-side. The door handle 263 can be made of high-strength stainless steel to prevent rust and corrosion from prolonged outdoor exposure.

[0055] In one example, the thickness of the door frame 10 is no more than 50mm, which increases the internal usable area of ​​the box-type power supply while the door lock 261 does not protrude from the outer surface of the box-type power supply.

[0056] Please see Figure 3 and Figure 4 In some embodiments, a first seal 27 is provided on the side of the two door bodies 20 that are close to each other, and the first seal 27 seals the gap between the two door bodies 20 on the side that are close to each other. In this way, the first seal 27 can reduce the passage of foreign objects such as liquids through the fire door 100 from the side of the two door bodies 20 that are close to each other, thereby improving the sealing performance of the fire door 100.

[0057] In one example, the first seal 27 can be made of fluororubber (FKM), which has the advantages of oil resistance, chemical corrosion resistance, and excellent high-temperature performance. It is suitable for harsh marine environments and can maintain airtightness and watertightness under high-temperature and fire-resistant conditions. The compression of the first seal 27 is designed to be 20%-30%, which has good resilience and avoids the deformation of the box-type power supply leading to seal failure.

[0058] Please see Figure 3 and Figure 5In some embodiments, the door body 20 further includes a sealing plate 28 disposed on the side of the first door panel 21 and the second door panel 22 near the door frame 10. A second sealing member 29 is provided between the sealing plate 28 and the door frame 10, and the second sealing member 29 seals the gap between the sealing plate 28 and the door frame 10. In this way, the second sealing member 29 can seal the gap between the door body 20 and the door frame 10, thereby reducing the passage of foreign objects such as liquids through the gap between the door body 20 and the door frame 100 through the fire door 100, and improving the sealing performance of the fire door 100.

[0059] Specifically, the sealing plate 28 can be bent. Similarly, the second seal 29 can be made of fluororubber (FKM), which has advantages such as oil resistance, chemical corrosion resistance, and excellent high-temperature performance, making it suitable for harsh marine environments. It can maintain airtightness and watertightness even under high-temperature and fire-resistant conditions. The compression of the second seal 29 is designed to be 20%-30%, providing excellent resilience and preventing seal failure due to deformation of the box-type power supply. The second seal 29 and the first seal 27 can be an integral structure forming a ring. The annular seal can surround the door frame 10 and the door body 20, as well as between the two door bodies 20.

[0060] In some embodiments, at least a portion of the outer surfaces of the door frame 10 and the door body 20 are coated with an anti-corrosion layer (not shown). This anti-corrosion layer can improve the corrosion resistance of the fire door 100, thereby increasing its lifespan.

[0061] In one example, the anti-corrosion layer can be a paint layer, and the paint layer can have multiple layers. In one example, the paint layer has a 3-layer structure, consisting of a zinc-rich primer, an epoxy resin paint, and a polyurethane topcoat, from primer to topcoat. The total thickness of the paint layer is not less than 260μm, which meets the outdoor C5 anti-corrosion rating requirements.

[0062] In some embodiments, the flexural strength of the fireproof board 23 is ≥10 MPa. This high flexural strength of the fireproof board 23 improves the flexural resistance of the door 20, making it less prone to deformation.

[0063] In some embodiments, the fireproof board 23 comprises a calcium silicate board. Thus, the fireproof board 23 has good fire resistance and high strength, and while providing fire protection, it can also improve the flexural strength of the fireproof board 23.

[0064] Specifically, calcium silicate boards are resistant to deformation, have high mechanical strength, and low water absorption, making them suitable for the high-temperature and high-humidity environment of ships. They are also easy to cut and install, thus improving the fire resistance and bending resistance requirements of fire doors 100. In one example, the fireproof board 23 has a thickness of 5-18mm, withstands temperatures up to 1000℃, and meets the A120 fire rating.

[0065] In some embodiments, the filler 25 is a biodegradable filler. Thus, the filler 25 is easily decomposed, improving the environmental performance of the fire door 100. In one example, the filler 25 is a soluble fiber blanket, which, compared to conventional fire-resistant cotton (ceramic fiber), is biodegradable, harmless, and has a lower thermal conductivity.

[0066] Please see Figure 3 , Figure 6 and Figure 7 In some embodiments, the fire door 100 includes a latch 40 disposed on the door body 20, the latch 40 being detachably engaged with the top and / or bottom of the door frame 10. Alternatively, the latch 40 is detachably engaged with at least one of the top and bottom of the door frame 10. Thus, the door body 20 can be held closed by the latch 40, improving the stability of the door body 20 when closed.

[0067] Specifically, the latch 40 can be located inside one of the doors 20. After one of the doors 20 is opened, it can enter the box-type power supply and push the latch 40 so that the other door 20 can also be opened.

[0068] In summary, in one example, the fire door 100 of this application embodiment can meet the maximum deformation of 12mm and satisfy the outdoor A60 fire protection requirement.
