[0002] In current chemical formation system production lines, multiple fire water tanks are typically installed to ensure fire safety during production. Currently, the industry generally adopts an independent fire water tank solution, where each fire water tank is configured as a separate device.

[0003] A typical chemical formation system production line requires at least 10 fire-fighting water tanks. Not only is the equipment itself expensive, but its installation, commissioning, and subsequent maintenance costs are also high. Furthermore, a large number of freestanding water tanks occupy a significant amount of floor space, resulting in wasted space. For example... Figure 1 One related technology shown involves setting up multiple static shelves, with an independent fire water tank installed around each of the static shelves. Furthermore, a working space for a stacker crane needs to be reserved between the fire water tank and the static warehouse, which occupies a large amount of space and results in low space utilization. Utility Model Content

[0004] In view of this, the present invention provides a fire-fighting static storage warehouse for lithium battery production lines to solve the problems of large floor space and high equipment cost of fire-fighting water tanks.

[0005] In a first aspect, this utility model provides a fire-resistant storage warehouse for a lithium battery production line, including shelves and a fire protection system: the shelves have at least two storage locations, one of which is a fire-resistant storage location for handling batteries that catch fire, and the rest are storage locations for storing batteries; the fire protection system includes fire-resistant pipes, which include a first fire-resistant branch and a second fire-resistant branch, the first fire-resistant branch extending to the fire-resistant storage location and the second fire-resistant branch extending to the storage location.

[0006] Beneficial Effects: The fire-fighting static storage warehouse for lithium battery production lines provided in this embodiment integrates two functions: battery fire handling and battery storage. The shelving is divided into fire-fighting and static storage areas, making full use of the factory's vertical space, reducing floor space, and improving space utilization. Furthermore, since the fire-fighting and static storage areas are integrated into one shelving unit, centralized management and monitoring are facilitated, reducing the workload of operators and improving work efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In such Figure 1 In one related technology shown, multiple stationary shelves 4 are installed in the factory building, and an independent fire water tank 3 is installed around each of the stationary shelves 4. Furthermore, working space for a stacker crane needs to be reserved between the fire water tank 3 and the stationary shelves 4. Figure 1 As shown by the dotted line, this layout occupies a lot of space, resulting in low space utilization.

[0021] The following is combined with Figures 2 to 8 The following describes embodiments of the present invention.

[0022] According to an embodiment of the present invention, in a first aspect, a fire-resistant storage warehouse for a lithium battery production line is provided, comprising a shelf 1 and a fire-fighting system 2. The shelf 1 has at least two storage locations 11, one of which is a fire-resistant storage location 111 for handling batteries that catch fire, and the other is a storage location 112 for storing batteries; the fire-fighting system 2 includes a fire-fighting pipe 21, which includes a first fire-fighting branch 212 and a second fire-fighting branch 213, the first fire-fighting branch 212 extending to the fire-fighting storage location 111, and the second fire-fighting branch 213 extending to the storage location 112.

[0023] The fire-fighting storage unit for lithium battery production lines provided in this embodiment of the invention is a rack 1 divided into fire-fighting storage space 111 and storage space 112, integrating both battery fire handling and battery storage functions. It fully utilizes the vertical space of the factory, reduces the floor space occupied, and improves space utilization. Furthermore, since the fire-fighting storage space 111 and storage space 112 are integrated into one rack 1, centralized management and monitoring are facilitated, reducing the workload of operators and improving work efficiency. The fire-fighting storage space 111 and storage space 112 are each equipped with a separate fire branch, allowing for independent maintenance, reducing the complexity and cost of daily maintenance, improving system reliability, and lowering investment and operating costs.

[0024] In some embodiments, the fire storage location 111 is located below the stationary storage location 112 and at the corner of the shelf 1.

[0025] Specifically, the shelf 1 can be set with multiple storage locations 11 along the height direction or along the horizontal direction.

[0026] When a shelf 1 is equipped with multiple storage locations 11 along its height, this arrangement can effectively utilize the vertical space of the factory and reduce the floor space occupied.

[0027] When a shelf 1 is set with multiple storage locations 11 along the horizontal direction, the fire-fighting storage locations 111 are distributed at both ends or either end of the shelf 1.

[0028] Setting the fire storage location 111 at the corner of the shelf 1 can reduce the impact on the batteries stored in other stationary storage locations 112, and is more conducive to the storage and operation of the stacker crane.

[0029] In some embodiments, the fire storage compartment 111 includes partitions 113 spaced apart along the height direction of the shelf 1, side panels 114 connected between two partitions 113, and a back panel 115 connected to both the two partitions 113 and the two side panels 114. The side opposite to the back panel 115 is the open side.

[0030] Since fire spreads upwards, the two partitions 113 spaced apart in the vertical direction serve as the main fire barriers, effectively preventing the spread of flames and high temperatures.

[0031] Side panels 114 and back panels 115 are tightly connected to partitions 113, making storage compartment 11 enclosed on five sides, which serves as a high-temperature shield to prevent high temperatures from spreading to other storage compartments 11. Storage compartment 11 has only one opening, which can be used to place battery trays 117.

[0032] In some embodiments, the back panel 115 is provided with a first mounting hole, through which the first fire branch 212 extends into the fire storage compartment 111.

[0033] The first fire branch 212 extends through the back panel 115 into the fire compartment 111, thus branching off from the second fire branch 213, facilitating initial installation and subsequent maintenance. Technicians can directly access the pipes from one side of the back panel for inspection or repair without disassembling numerous other components.

[0034] In some embodiments, the fire storage compartment 111 is provided with at least one support plate 119, which divides the interior of the fire storage compartment 111 into at least two fire spaces along the height direction. The support plate 119 is provided with a hollow structure to allow adjacent fire spaces to be connected.

[0035] By installing the support plate 119, batteries can be placed in layers inside the fire-fighting storage compartment 111, facilitating the subsequent disposal of used batteries. The support plate 119 rationally divides the limited space, making full use of vertical space and increasing the processing capacity of the fire-fighting storage compartment 111 without increasing its floor space.

[0036] Because the support plate 119 has a hollow structure, the adjacent fire-fighting spaces are interconnected. That is, when the fire-fighting storage space 111 is used for fire sprinkler, the sprinkler water can continue to flow downward through the hollow structure of the support plate 119, ensuring the fire-fighting effect in the fire-fighting storage space 111.

[0037] In some embodiments, in the fire-fighting storage compartment 111, the partition 113, side panel 114, and back panel 115 are all fireproof boards.

[0038] Since fire storage compartment 111 is used to handle batteries that catch fire, it has higher fire protection requirements. The partitions 113, side panels 114 and back panels 115 of fire storage compartment 111 are all made of fireproof boards, which can form an effective five-sided enclosed fireproof structure to prevent the fire and heat from spreading to other storage compartments and effectively improve the fire protection effect of the fire storage compartment.

[0039] Specifically, fireproof boards include one or a combination of several of the following: gypsum board, calcium silicate board, perlite fireproof board, vermiculite fireproof board, or composite fireproof board (composed of multiple layers of different materials, such as metal foil, fire-resistant fiber, flame-retardant plastic, etc.).

[0040] In some embodiments, the opposite side walls of the fire storage compartment 111 are provided with support frames 118, and the two support frames 118 constitute a support platform for supporting the battery tray 117; when the battery tray 117 is placed on the support platform, the battery tray 117 and the partition 113, the side plate 114 and the back plate 115 are spaced apart.

[0041] The support frame 118 is located on both sides of the storage location 11, forming a stable support platform that can support the battery tray 117. At the same time, it can reduce the space occupied by the support frame 118 in the storage location 11. The support frame 118 is reasonably designed, which makes it easy for operators to quickly access the battery tray 117, reduces access time, and improves work efficiency.

[0042] In some embodiments, a drip tray 116 is also included, which is located at the bottom of the fire storage compartment 111.

[0043] The primary function of the drip tray 116 is to collect any leaked liquid that may occur after a battery fire. By directing this liquid into the drip tray 116, it is effectively prevented from flowing onto the ground or other areas, avoiding pollution or damage to the environment and facilities. Leaking battery liquid is concentrated in a specific area, facilitating regular cleaning and disposal. Maintenance personnel only need to inspect and clean the drip tray 116, reducing workload and improving work efficiency.

[0044] In some embodiments, the fire protection system 2 further includes a first sprinkler head 22 located in the fire storage location 111 and a second sprinkler head 23 located in the stationary storage location 112. The first sprinkler head 22 is connected to the first fire branch 212, and the second sprinkler head 23 is connected to the second fire branch 213. The first sprinkler head 22 is a normally open sprinkler head; and / or, the second sprinkler head 23 is a normally closed sprinkler head.

[0045] The fire-fighting storage compartment 111 is equipped with a first sprinkler head 22, and the stationary storage compartment 112 is equipped with a second sprinkler head 23. The two sprinkler heads are connected to the fire-fighting pipeline 21, enabling rapid response and precise fire suppression. In the event of a fire, the sprinkler system can be quickly activated to reduce fire damage.

[0046] The first sprinkler head 22 is a normally open sprinkler head. Normally open sprinkler heads remain open under normal circumstances. Once a fire signal is detected (such as increased temperature or smoke), the sprinkler system can immediately activate and begin spraying water. Compared to traditional closed sprinkler heads, normally open sprinkler heads do not require waiting for the heat-sensitive element to melt or break, enabling a more rapid response to a fire and reducing the time it takes for the fire to spread. Because the sprinkler head is always open, there is no activation delay, ensuring timely fire suppression in the early stages of a fire and minimizing the damage caused by the fire.

[0047] The second sprinkler head 23 is a normally closed sprinkler head. Normally closed sprinkler heads remain closed under normal circumstances and only automatically open when a fire signal (such as increased temperature, smoke, or flame) is detected. Normally closed sprinkler heads are equipped with heat-sensitive elements (such as glass bulbs or fusible metals). When the ambient temperature reaches a set threshold, these elements rupture or melt, thereby opening the sprinkler head to spray water. The sprinkler head's built-in automatic start mechanism can respond quickly and open in the event of a fire, ensuring timely water supply for firefighting. The sprinkler head can continuously supply water through the fire-fighting pipeline 21 until the fire is extinguished or manually shut off, ensuring a stable water flow during the firefighting process and enhancing the firefighting effect.

[0048] In some embodiments, a flue gas recovery pipe is also included, one end of which extends into the fire-fighting storage compartment 111, and the other end of which is connected to the flue gas recovery system.

[0049] The flue gas recovery pipe can promptly extract harmful fumes generated during a fire from the fire-fighting storage area, reducing the harm of toxic gases to internal fire-fighting equipment and rescue personnel, and meeting the environmental protection requirements of the factory. Simultaneously, rapid smoke extraction helps lower the temperature inside the factory, mitigating the impact of the fire on batteries stored in other areas.

[0050] In some embodiments, the stationary storage location 112 includes partitions 113 spaced apart along the height direction of the shelf 1, side panels 114 connected between two partitions 113, and a back panel 115 connected to both the two partitions 113 and the two side panels 114. The side opposite to the back panel 115 is an open side. The side panel 114 is provided with a second mounting hole, and a second fire branch 213 extends through the second mounting hole into the stationary storage location 112.

[0051] Each storage location 11 is equipped with a five-sided fireproof structure, which ensures that each storage location 11 is independent of each other and effectively prevents the spread of fire and high temperature.

[0052] For the stationary storage location 112, unlike the installation route of the first fire branch 212, the second fire branch 213 extends into the stationary storage location 112 through the second installation hole. In this way, the first fire branch 212 and the second fire branch 213 are installed independently without interfering with each other. The pipeline route is reasonable and the layout is clear. The first fire branch 212 and the second fire branch 213 can operate independently of each other, ensuring the fire protection effect.

[0053] The fire-resistant storage warehouse for the lithium battery production line provided in this embodiment is equipped with a dedicated fire-resistant storage location 111 for handling batteries that catch fire. Both the fire-resistant storage location 111 and the storage location 112 are fire-resistant zones, effectively isolating potential fire sources and preventing the fire from spreading to other storage locations 11, thus ensuring the safety of the entire production line.

[0054] Furthermore, in some embodiments, in order to further improve the fireproof isolation effect, a joint sealing plate can be provided in the gap between the partition 113 and the side plate 114, and in the gap between the partition 113 and the back plate 115, to fill the gap between the two adjacent plates.

[0055] In some embodiments, the fire protection pipeline 21 includes a water distribution pipe 211, which is located on one side of the shelf 1 and extends along the height direction of the shelf 1. A first fire branch 212 connects the first sprinkler head 22 to the water distribution pipe 211, and a second fire branch 213 connects the second sprinkler head 23 to the water distribution pipe 211.

[0056] Fire-fighting storage location 111 and static storage location 112 are connected to the water distribution pipe 211 via different fire-fighting branch lines and are each equipped with a control valve, enabling independent fire protection for fire-fighting storage locations 111 and static storage locations 112, and allowing independent control of the sprinkler heads in different storage locations 11. In the event of a fire, only the sprinkler heads in the affected storage location 11 can be activated according to the actual situation, avoiding unnecessary waste of water resources and improving the system's flexibility and response speed.

[0057] The first fire branch 212 connects to the first sprinkler head 22, and the second fire branch 213 connects to the second sprinkler head 23, thus achieving multi-point water supply and ensuring that each sprinkler head can obtain sufficient water, thereby enhancing the timeliness and effectiveness of fire extinguishing.

[0058] When multiple static storage locations 112 are set up, the second sprinkler head 23 in each static storage location 112 is connected to the water distribution pipe 211 through the second fire branch 213.

[0059] In some embodiments, multiple shelves 1 are spaced apart in the horizontal direction; the fire pipeline 21 also includes a water distribution main pipe 214, with each or every two shelves 1 corresponding to a water distribution pipe 211, and each water distribution pipe 211 is connected to the water distribution main pipe 214.

[0060] When multiple rows of shelves 1 are set up, each shelf 1 is equipped with a corresponding water distribution pipe 211, and the multiple water distribution pipes 211 are respectively connected to the main water distribution pipe 214. Alternatively, a water distribution pipe 211 can be set up for every two shelves 1, with the water distribution pipe 211 located between the two shelves 1, and the two shelves 1 sharing a single water distribution pipe 211. The stationary storage positions 112 on both sides of the water distribution pipe 211 are respectively connected to the water distribution pipe 211 through the second fire branch 213.

[0061] In some embodiments, the fire protection system 2 further includes a first control valve 24 and a second control valve 25. The first control valve 24 is located on a first fire branch 212 outside the fire storage location, and the second control valve 25 is located on a second fire branch 213 outside the stationary storage location.

[0062] Specifically, the water distribution pipe 211 is located on one side of the shelf 1. The first fire branch 212, connected to the water distribution pipe 211, extends to the rear of the shelf 1, passes through the back panel 115, and enters the fire storage compartment 111, connecting to the first sprinkler head 22. The second fire branch 213, connected to the water distribution pipe 211, directly passes through the side panel 114 and enters the stationary storage compartment 112, connecting to the second sprinkler head 23. In this way, the two sets of fire pipes in the fire storage compartment 111 and the stationary storage compartment 112 can be rationally arranged to ensure rapid and timely fire suppression.

[0063] By placing the first control valve 24 and the second control valve 25 outside the fire-resistant area, the control valves can be protected from the high temperatures of a fire, ensuring their continued normal operation during a fire. Simultaneously, operators can directly operate these valves from the outside, facilitating inspection and maintenance.

[0064] Furthermore, the first control valve 24 is a valve group structure consisting of a manual control valve and an electric control valve connected in parallel, which enables manual or automatic sprinkler fire suppression.

[0065] In some embodiments, the fire protection system 2 further includes a water flow indicator 26 and a drain valve 27, wherein the water flow indicator 26 is located on the first fire branch 212 and the drain valve 27 is located on the water distribution pipe.

[0066] The water flow indicator 26 can monitor the water flow in the water distribution branch pipe in real time to ensure that there is fire water supply in the fire pipeline 21, thereby ensuring sufficient water supply when fire fighting is required.

[0067] The drain valve 27 can drain accumulated water from the pipes after a fire is extinguished or the system test is completed, preventing corrosion, freezing, and other problems caused by long-term water retention in the pipes, thus extending the service life of the pipes and equipment. At the same time, it simplifies daily maintenance, reduces the need for manual drainage, and lowers maintenance costs and labor intensity.

[0068] In some embodiments, a stacker crane is also included, which is equipped with a fire extinguishing device and is adapted to place batteries in any storage location 11.

[0069] The stacker crane is equipped with a fire extinguishing system that can respond to potential fire risks in real time during handling. If a fire is detected, the fire extinguishing system can be activated immediately to quickly extinguish the initial fire and prevent its spread. Since the stacker crane can move freely within the storage area and place batteries in any storage location 11, it can handle the batteries. Normal batteries are placed in the stationary storage location 112. If a battery catches fire during handling, the stacker crane's fire extinguishing system will activate to initially extinguish the fire and control the fire, while simultaneously moving the burning battery to the fire-fighting storage location 111.

[0070] The stacker crane's flexibility allows it to precisely place batteries in any designated storage location 11 without manual intervention, improving work efficiency and reducing labor costs. Furthermore, the stacker crane can be adjusted according to the specific requirements of different storage locations 11 (such as height and position), flexibly adapting to various storage environments and enhancing the system's applicability.

[0071] When the stacker crane detects an anomaly, it can immediately activate the fire extinguishing system and simultaneously send an alarm signal to the control system, notifying relevant personnel to take further measures, thus improving the speed and efficiency of emergency response. The stacker crane's fire extinguishing system works in conjunction with other fire-fighting facilities within the warehouse area, forming a multi-layered fire safety system that provides more comprehensive protection, further improving the system's fire reliability, simplifying the configuration of fire hydrants, and reducing construction and maintenance costs.

[0072] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
