However, if the battery falls from the shelf into the aisle during the taking and placing process, there is no corresponding fire extinguishing measure in the aisle, and the battery continues to burn in the aisle after falling and catching fire, which will burn the stacker slide wire and the surrounding equipment near the fire position, and will cause a serious chain reaction, thereby causing a large safety risk.

[0020] The embodiments of the present application will be described below in combination with Figures 1 to 4 The embodiments of the present application will be described below in combination with

[0021] According to the embodiments of the present application, on the one hand, a storage warehouse bottom fire extinguishing device is provided, which comprises a stereoscopic shelf 1, a bottom fire pipe 3 and a first fire nozzle 4.

[0022] The stereoscopic shelf 1 comprises a plurality of layers of storage positions; one side of the stereoscopic shelf 1 is provided with an aisle 2; the bottom fire pipe 3 is arranged below the bottom layer of the stereoscopic shelf 1, and a fire extinguishing agent is introduced into the bottom fire pipe 3; the first fire nozzle 4 is connected to the bottom fire pipe 3, and the first fire nozzle 4 is arranged towards the aisle 2. The aisle 2 is a space for transporting batteries or for personnel to walk, or a space beside a storage position for placing batteries.

[0023] The storage warehouse bottom fire extinguishing device has the bottom fire pipe 3 arranged at the bottom of the stereoscopic shelf 1, the bottom fire pipe 3 is connected to the first fire nozzle 4, the first fire nozzle 4 is arranged towards the aisle 2, and the battery is stored in the storage position of the stereoscopic shelf 1. One side of the stereoscopic shelf 1 is the aisle 2, when the battery falls into the aisle 2 and catches fire during the taking and placing process, the first fire nozzle 4 sprays the fire extinguishing agent, which can extinguish the fire source in time, prevent the fire from spreading, and thus can avoid burning the stacker slide wire and the surrounding equipment near the fire position, which is beneficial to improving the safety of the storage warehouse.

[0024] In some optional embodiments, the bottom fire pipe 3 is introduced with fire water, and when the aisle 2 catches fire, the first fire nozzle 4 sprays water towards the aisle 2 to extinguish the fire source in time.

[0025] In some optional embodiments, the first fire nozzle 4 comprises a passive nozzle. The passive nozzle refers to a nozzle that can automatically open and start spraying water to extinguish the fire when the fire occurs. The first fire nozzle 4 adopts the passive nozzle, and when the fire source appears in the aisle 2 and the temperature or generated smoke reaches the opening condition of the passive nozzle, the first fire nozzle 4 sprays water, which can effectively prevent false triggering; at the same time, when the open fire appears, the first fire nozzle 4 directly sprays water towards the fire point in the aisle 2, the first fire nozzle 4 is sensitive and timely in response, and can effectively extinguish the fire source in time.

[0026] Optionally, in some embodiments, the passive sprinkler comprises a glass bulb sprinkler. The glass bulb sprinkler breaks directly to spray the ignition point after the appearance of an open fire in the aisle 2, and the sprinkler is sensitive and timely in response. The storage warehouse for storing the batteries comprises a normal temperature static storage and a high temperature static storage, and the normal temperature static storage and the high temperature static storage have different optimal response temperatures for opening the sprinkler when a fire source appears in the storage warehouse. The glass bulb sprinkler is a standard part, which has multiple different action temperatures, and the action temperature is close to the optimal response temperature for opening the sprinkler of the normal temperature static storage and the high temperature static storage. The glass bulb sprinkler can open the sprinkler at the optimal response temperature for opening the sprinkler of the normal temperature static storage and the high temperature static storage, which is conducive to timely extinguishing the fire source and can keep the normal temperature static storage and the high temperature static storage in a suitable temperature range. The glass bulb sprinkler does not need to be controlled by the system judgment of the fire signal and the control system to start the first fire sprinkler 4, and the first fire sprinkler 4 is sensitive and timely in response, which can greatly reduce the response time of the first fire sprinkler 4, so as to effectively extinguish the fire source in time.

[0027] In other embodiments, the passive sprinkler comprises a fusible alloy sprinkler or an induction sprinkler, and optionally, the induction sprinkler comprises a smoke sprinkler.

[0028] As shown in Figure 1 , Figure 2 and Figure 4 , in some embodiments, the bottom fire pipe 3 comprises a main pipe 31 and a plurality of branch pipes 32, the main pipe 31 extends along the length direction of the stereoscopic shelf 1; the branch pipes 32 communicate with the main pipe 31, and the plurality of branch pipes 32 are arranged at intervals along the length direction of the main pipe 31; the first fire sprinkler 4 is provided in plurality, and the plurality of first fire sprinklers 4 are arranged one by one on the branch pipes 32. The bottom fire pipe 3 communicates the plurality of branch pipes 32 through one main pipe 31, and one first fire sprinkler 4 is arranged on each branch pipe 32, so that water supply of the plurality of first fire sprinklers 4 can be realized through one main pipe 31, and the structure of the bottom fire device can be simplified. Figure 1 and Figure 2 , the main pipe 31 extends along the length direction (the left-right direction in Figure 1 ) of the stereoscopic shelf 1, and the branch pipes 32 are arranged at intervals along the length direction of the main pipe 31, so as to arrange the plurality of first fire sprinklers 4 at intervals in the length direction of the stereoscopic shelf 1. When the battery falls into the aisle 2 to ignite, the first fire sprinkler 4 close to the ignition point breaks to spray the ignition point, which is convenient for arranging full fire points in the length direction of the aisle 2.

[0029] In some embodiments, the end of the branch pipe 32 away from the main pipe 31 is inclined downward. This arrangement allows the end of the branch pipe 32 connected to the first fire sprinkler head 4 to be inclined downward. When the main pipe 31 and the branch pipe 32 are filled with fire water, and when a fire breaks out in the tunnel 2 and the temperature reaches the rupture temperature of the first fire sprinkler head 4, the downward inclination of the branch pipe 32 is more conducive to the automatic spraying of fire water under the action of gravity.

[0030] Optionally, in some embodiments, the branch pipe 32 is tilted downward at an angle of 'a', 30°≤a≤60°. The downward tilt angle of the branch pipe 32 is moderate, which can ensure the spray angle and spray range of the nozzle while facilitating water output from the nozzle.

[0031] In other embodiments, the branch pipe 32 is arranged horizontally.

[0032] In some embodiments, the height of the bottom slab of the ground floor from the ground is H, and the distance of the first fire sprinkler head 4 from the ground is h. This setting ensures the height of the first fire sprinkler head 4, preventing it from being too low and affecting its spray range, thus guaranteeing the spraying effect of the first fire sprinkler head 4.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, along the length of the automated shelving 1, adjacent first fire sprinklers 4 are positioned below different storage locations, and adjacent first fire sprinklers 4 are spaced apart by at least one storage location. Since the spray range of the first fire sprinklers 4 is relatively wide, and adjacent first fire sprinklers 4 are spaced apart by at least one storage location, the number of first fire sprinklers 4 can be reduced while ensuring that the spray range of the sprinklers can effectively extinguish the fire, thus saving costs.

[0034] Optionally, in some embodiments, two adjacent first fire sprinklers 4 are spaced apart by one storage space, and the spray range of the two adjacent first fire sprinklers 4 covers the alleyway 2 area in front of the storage space between them.

[0035] In some embodiments, such as Figure 4 As shown, there are two branch pipes 32, located at both ends of the main pipe 31. The bottom fire pipe 3 has a simple and reliable structure. Each main pipe 31 spans three storage locations, and the two branch pipes 32 at both ends of each main pipe 31 are spaced one storage location apart, which facilitates the placement of the first fire sprinkler head 4 at the spaced storage locations.

[0036] In some alternative embodiments, the branch pipe 32 is integrally formed with the main pipe 31, and the bottom fire-fighting pipe 3 has a stable and reliable structure. In some implementations, the branch pipe 32 is perpendicular to the main pipe 31.

[0037] In some embodiments, the stereoscopic shelf 1 comprises a support frame 5, and the bottom fire pipe 3 is connected to the support frame 5. The bottom fire pipe 3 is connected and fixed by using the existing support frame 5 structure of the stereoscopic shelf 1, so that the bottom fire pipe 3 is conveniently and quickly fixed, and no additional space is occupied outside the stereoscopic shelf 1, and the bottom fire of the stereoscopic shelf 1 is increased without increasing the additional occupied space.

[0040] In some optional embodiments, as shown in Figure 2 The warehousing vertical store bottom fire device further comprises an agent inlet pipe, one end of the agent inlet pipe is an agent inlet end, and the other end is an agent outlet end, the fire extinguishing agent enters through the agent inlet end and is discharged through the agent outlet end after extinguishing. The bottom fire pipe 3 is communicated with the agent inlet pipe, and the bottom fire device uses the fire pipe of the warehousing vertical store fire fighting system to introduce fire water, so that the bottom fire device and the water inlet pipe of the fire in the storage location can simplify the pipeline arrangement of the entire warehousing vertical store fire fighting system.

[0041] The warehousing vertical store fire fighting system is used for fire fighting in each storage location, and good control of fire in the storage location is realized.

[0042] In some embodiments, the warehousing vertical store fire fighting system further comprises a manual control valve, a water flow indicator, a terminal water testing device and a drain valve.

[0043] In some embodiments, the manual control valve is arranged at the front end of the agent inlet pipe, and fire water can enter the warehousing vertical store fire fighting system by opening the manual control valve.
