Description

Technical Field

[0002] Containerized energy storage systems are integrated energy storage systems developed to meet the needs of the mobile energy storage market. They integrate battery cabinets, battery management systems, and container environmental monitoring systems, and can also integrate energy storage converters and energy management systems according to customer needs. Containerized energy storage systems have the characteristics of simplified infrastructure construction costs, short construction cycles, high modularity, and easy transportation and installation. They are suitable for applications such as thermal power, wind power, solar power, and other power plants, as well as islands, residential areas, schools, research institutions, factories, and large load centers.

[0003] Containerized energy storage systems, due to their internal battery compartments (including batteries, battery racks, BMS control cabinets, etc.), typically require fireproofing of the storage containers to ensure isolation from the outside environment in the event of a fire, thus preventing impact on surrounding containers. Existing energy storage container doors usually only provide fireproofing at the joint between the door body and frame or on the inside of the door. However, in the event of a fire, smoke and flames can easily escape through gaps in the top of the container, causing the fire to spread further. Therefore, this application proposes a fireproof door and an energy storage container incorporating it to reduce the spread of fire during a fire, improve the protective effect of the fireproof door, and minimize the impact on surrounding containers.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0060] Figure 1 This is a structural schematic diagram of a fire door according to one embodiment of the present application. The fire door can be used in containers and includes: a frame 1; at least two door bodies 2 configured to be rotatably mounted on the inner side of the frame 1 at one end and connected to each other at the other end to close the frame 1; an inner fireproof component 3; an outer fireproof component 4 disposed on the outer side of the joint of the two door bodies 2 and configured to form a baffle groove to block the extension of fire when heated; and a top fireproof unit 5. The inner fireproof component 3 is configured to include at least an expansion member 31 disposed in the gap between the door body 2 and the frame 1, and an inner fireproof unit 32 installed on the inner side of the joint of the two door bodies 2. The top fireproof unit 5 is pressed against the top of the inner fireproof unit 32 and connected to the frame 1, and is configured to expand when heated to seal the gap between the inner fireproof unit 32 and the frame 1.

[0061] Under this arrangement, refer to Figure 1 and Figure 2The fire door described in this article, by incorporating an internal fire-resistant component 3, effectively prevents fire damage to the gaps between the door body 2 and the frame 1, as well as the gaps between adjacent door body 2, through the expansion member 31 and the internal fire-resistant unit 32 located on the inner side of the connection between the two door bodies 2. The external fire-resistant component 4 located on the outer side of the connection between the two door bodies 2 facilitates the formation of a groove to block the spread of fire when heated, thus preventing the spread of fire to a wider area when the internal fire-resistant unit is damaged, thereby effectively improving the protective effect of the fire door. The top fire-resistant unit 5 facilitates the sealing of the connection between the internal fire-resistant component 3 and the frame 1, and expands when heated to seal the gap between the internal fire-resistant unit 32 and the frame 1, further ensuring the fire resistance of the door body 2 and reducing the impact on surrounding equipment.

[0062] It is understood that the aforementioned fire doors can be used in energy storage containers. By improving the fire resistance of the fire doors, effective fire prevention can be achieved inside the energy storage container. In the event of thermal runaway or fire in the container, the fire inside the container can be effectively contained, thereby reducing the risk of fire spreading over a wider area.

[0063] It should be noted that the fire door described above can also be applied to ordinary containers. The fire door can effectively reduce the risk of fire spread in the event of a fire in the container. Of course, the fire door described above can also be applied to energy storage cabinets or other electrical equipment. Therefore, the specific application scenarios of this fire door are not limiting provisions of this embodiment.

[0064] The following will illustrate further specific implementations or refinements of the board enclosure assembly through exemplary description, in order to further improve it or for other improvement considerations.

[0065] Further reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The internal fireproof unit 32 includes a first pressure plate 321 and a first expansion member 322. The first pressure plate 321 is configured such that one end is fixedly connected to the inner wall of one of the two door bodies 2, and the other end extends to a position opposite to the gap at the joint of the two door bodies 2 and is spaced a distance from the door body 2. The first expansion member 322 is fixedly installed on the side of the first pressure plate 321 near the door body 2 and opposite to the gap between the two door bodies 2, and is configured to expand when heated to seal the gap between the two door bodies 2. Both the first pressure plate 321 and the first expansion member 322 extend from the bottom end to the top end of the door body 2.

[0066] It is easy to see that by setting the first pressure plate 321, a structural foundation is provided for the installation of the first expansion member 322, so that the first expansion member 322 can expand when heated, thereby sealing the gap between the first pressure plate 321 and the door body 2, so as to achieve effective sealing of the inner side between two adjacent door bodies 2, and ensure that fire or smoke will not flow out from between the two door bodies 2.

[0067] Furthermore, refer to Figure 2 , Figure 4 , Figure 7 and Figure 9 The external fireproof component 4 includes: a second pressure plate 41 and a second expansion member 42. The second pressure plate 41 is configured such that one end is fixedly connected to the outer wall of one of the two door bodies 2, and the other end extends to the outside of the other of the two door bodies 2 and forms a gap with the door body 2. The second expansion member 42 is fixedly installed on the side of the second pressure plate 41 near the door body 2 and located in the aforementioned gap, and is configured to expand when heated to seal the gap between the second pressure plate 41 and the door body 2. The second pressure plate 41 protrudes outward at the middle position to splice with the second expansion member 42 when it expands to form the partition groove. Both the second pressure plate 41 and the second expansion member 42 extend from the bottom end to the top end of the door body 2.

[0068] It can be understood that by setting the second pressure plate 41, it is convenient to assist in the installation of the second expansion member 42. By utilizing the gap formed between the other end of the second pressure plate 41 and the door body 2, it is convenient to install the second expansion member 42 on the side of the door body 2 at the other end. The second pressure plate 41 protrudes outward at the middle position, so that when the inner fireproof unit 32 fails, the protruding structure can still be used to block the fire, so as to prevent the internal fire from spreading rapidly to the surrounding equipment, thereby reducing the impact on the surrounding equipment.

[0069] It should be noted that both the second expansion member 42 and the second pressure plate 41 extend from the bottom to the top of the door body 2, thereby achieving external protection between the two door bodies 2 from bottom to top. When the second expansion member 42 expands, it can cooperate with the second pressure plate 41 to form a groove structure, which not only reduces the risk of fire spreading outward, but also effectively reduces the amplification effect of external wind on the gap of the door body 2 in the event of a fire, further improving the reliability of the fire door.

[0070] In one embodiment, reference is made to... Figure 4 , Figure 5 and Figure 6 The top fireproof unit 5 includes: a fireproof expansion strip 51 fixedly attached to the side of the first pressure plate 321 away from the door body 2 and configured to have its top end in contact with the expansion member 31; and a pressing member 52 fixedly pressed onto the side of the fireproof expansion strip 51 away from the first pressure plate 321 and configured to have its top end abut against the inner wall of the top of the frame 1.

[0071] It can be seen that the fire-resistant expansion strip 51 can effectively seal the gap between the inner top of the door body 2 and the frame 1. The fire-resistant expansion strip 51 is connected to the expansion member 31 by the pressing member 52, thereby sealing the gap at the inner top of the adjacent door body 2 and effectively sealing the gap between the top of the door body 2 and the frame 1. This reduces the risk of smoke or flames escaping from the top of the door body 2. Furthermore, the pressing member 52 further fixes and presses the top of the two door bodies 2 at the connection, further improving the pressure resistance of the top of the door body 2 and reducing the deformation that may be caused by smoke and gas pressure, thereby improving the fire resistance effect at the connection of the top of the adjacent door bodies 2.

[0072] It should be noted that the aforementioned top fireproof unit 5 can also extend along the bottom end of the door 2 to the top end, thereby providing further sealing and pressure for the inner fireproof unit 32 on the inside. Its specific form and structure are not limiting provisions of this embodiment.

[0073] In another embodiment, reference is made to... Figure 10 and Figure 11 The door body 2 includes: an inner panel 21, an outer panel 22 that is fitted and installed next to the inner panel 21, and a door panel insulation layer 23 that is filled inside the inner panel 21 and the outer panel 22.

[0074] It is easy to see that by setting the door body 2 as an inner panel 21, an outer panel 22 and a door panel insulation layer 23, the fire resistance of the door body 2 can be effectively improved. The door panel insulation layer 23 can effectively control heat conduction, reduce the heat transfer between the inner panel 21 and the outer panel 22 when a fire occurs, and further reduce the risk of fire spread.

[0075] Based on this, the inner plate 21 and the outer plate 22 are distributed in parallel, and the ends of the two near the outer side wall are fixed by spot welding.

[0076] It should be noted that by distributing the inner panel 21 and the outer panel 22 in parallel and fixing them together by spot welding, the heat transfer between the inner panel 21 and the outer panel 22 can be effectively reduced, thereby reducing the risk of heat spread when a fire occurs inside the door 2.

[0077] Further reference Figure 10 and Figure 11 It also includes: multiple reinforcing ribs 24 disposed inside the inner panel 21 and the outer panel 22 and arranged at intervals, and the door panel insulation layer 23 filling the gap between two adjacent reinforcing ribs 24.

[0078] It is easy to see that by using multiple reinforcing ribs 24 inside the inner panel 21 and the outer panel 22, the structural strength of the door body 2 can be improved, and it is also convenient to fill the door panel insulation layer 23 inside. In addition, it can further improve the fire resistance in the event of a fire inside the door body 2.

[0079] Furthermore, along the width direction of the door body 2, the reinforcing ribs 24 inside the inner panel 21 and the outer panel 22 are staggered, and the door panel insulation layer 23 inside the inner panel 21 and the outer panel 22 is staggered.

[0080] It can be understood that by staggering the reinforcing ribs 24 inside the inner panel 21 and the outer panel 22, the door panel insulation layer 23 inside the inner panel 21 and the outer panel 22 can be staggered along the width direction of the door body 2. As a result, the projection of the door panel insulation layer 23 is continuous on the projection surface along the width direction of the door body 2. Therefore, in the event of a fire, the door panel insulation layer 23 will always exist along the width direction of the door body 2 to block heat, thereby further preventing heat transfer from the door body 2 and reducing the risk of fire spread.

[0081] In one embodiment, the reinforcing rib 24 is configured to extend from one end of the door body 2 to the other end along the length direction, and both ends of the reinforcing rib 24 are provided with notches.

[0082] It is easy to see that by setting the reinforcing rib 24 to extend along the length of the door body 2, it is convenient to use it to support the door body 2 along the length direction. In addition, the notches set at both ends of the reinforcing rib 24 can reduce the heat transfer between the inner panel 21 and the outer panel 22, and improve the fire resistance of the door body 2 structure itself.

[0083] For example, the above-mentioned door panel insulation layer 23 can be a thermal insulation material such as rock wool, aerogel, or nano-insulation board, which can achieve heat insulation between the inner panel 21 and the outer panel 22 while ensuring the thermal insulation effect of the door body 2. Of course, other thermal insulation materials can also be selected, but this embodiment does not make specific limitations here.

[0084] For example, in addition to adopting a two-layer structure, the door body 2 can also be provided with decorative steel plates or thermal insulation cotton as needed. Regarding its specific structure, this embodiment does not make specific limitations here.

[0085] In another embodiment, reference is made to... Figure 7 and Figure 8The frame 1 includes an outer frame 11 and an inner frame 12. The inner frame 12 is fixedly connected to the inner side of the outer frame 11 and is configured to extend beyond the outer frame 11 along the width direction of the door 2 and form a corner with the outer frame 11. One end of the door 2 is accommodated in the corner and is rotatably connected to the outer frame 11. The expansion member 31 is fixed to the inner frame 12 located at the corner and is configured to expand when heated to seal the gap between the inner frame 12 and the door 2.

[0086] It can be seen that by setting the frame 1 as an outer frame 11 and an inner frame 12, and forming an angle between the two, it is not convenient to use the angle to realize the rotation installation of the door 2. The expansion member 31 is fixed on the side of the inner frame 1 close to the door 2 so that it can expand and seal the gap between the inner frame 1 and the door 2 when heated.

[0087] Based on this, refer to Figure 7 and Figure 8 It also includes: screws 13 that pass through the inner frame 12 and the outer frame 11 in sequence along the thickness direction, and / or a frame insulation layer 14 configured to fill the interior of the inner frame 12 and the outer frame 11.

[0088] It is easy to see that the screws 13, which are sequentially connected to the inner frame 12 and the outer frame 11, facilitate the installation and shaping of the frame 1. The frame insulation layer 14 filled inside both can further improve the heat insulation effect of the frame, reduce the heat transfer between the frame 1 and the outside when a fire occurs inside the door 2, further reduce the fire resistance of the fire door, and enhance the stability and sealing of the entire fire door system.

[0089] In practical applications, this embodiment should be referenced. Figure 7 , Figure 8 and Figure 9 It also includes: a waterproof component 6 configured to fill the gap between the door body 2 and the frame 1 and / or the gap at the connection of two adjacent door bodies 2, and / or a locking rod 7 disposed on the outside of the door body 2 and connected to the door body 2 in a one-to-one correspondence, the locking rod 7 being configured to connect to the locking block on the door body 2 to fix the two door bodies 2.

[0090] It should be noted that by filling the gaps between the door body 2 and the frame 1, as well as the gaps at the connection between two adjacent door bodies 2, the waterproof component 6 can effectively waterproof the gaps between the door body 2 and the frame 1, as well as the gaps at the connection between two door bodies 2, thus avoiding the impact of external water or debris on the interior of the door body 2.

[0091] In addition, the locking rod 7 and locking block can effectively fix the door 2, further enhancing the structural strength of the door 2 in the event of a fire.

[0092] For example, the expansion member 31 is configured as a fire-resistant expansion strip, and / or the waterproof member 6 is configured as a waterproof sealing strip. The first expansion member 41 and the second expansion member 42 can both be fire-resistant expansion strips. Of course, the above-mentioned expansion member 31, the first expansion member 41 and the second expansion member 42 can also be other types of fire-resistant components, as long as they can deform when heated and achieve fireproof sealing of the corresponding gaps. The specific types of expansion member 31, the first expansion member 41, the second expansion member 42 and the waterproof member 6 are not limiting provisions of this embodiment.

[0093] This embodiment also provides an energy storage container, including: a container body and a fireproof door installed on the container body as described above.

[0094] It can be seen that by applying the above-mentioned fireproof doors to energy storage containers, the gaps between the door body 2 and the frame 1, as well as the gaps between the adjacent door bodies 2, can be effectively prevented through the expansion member 31 and the inner fireproof unit 32 set inside the connection between the two door bodies 2. This not only meets the fire safety requirements of energy storage containers, but also effectively reduces the risk of fire spread when a fire occurs in the energy storage container, and ensures the stability and continuous operation capability of the energy storage system under extreme conditions.

[0095] Furthermore, by utilizing the external fireproof component 4 located on the outside of the connection between the two door bodies 2, a groove structure is formed to block the spread of fire when heated. This prevents the fire from spreading to a wider area when the inner fireproof unit 32 is damaged, thus effectively improving the protective effect of the fire door. By setting the top fireproof unit 5, it is easy to seal the top connection between the inner fireproof component 3 and the frame 1. When heated, it expands to seal the gap between the inner fireproof unit 32 and the frame 1, thereby reducing the impact on the surrounding energy storage containers.

[0096] The above examples primarily illustrate the fireproof door of this application and the energy storage container including the fireproof door. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
