DETAILED DESCRIPTION
[0016] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 4 As shown, an automatic fire fighting system for a reach stacker of this embodiment comprises a protective housing 1 and a plurality of lithium battery groups 2, wherein the plurality of lithium battery groups 2 are fixedly mounted in the protective housing 1, and the protective housing 1 covers and protects the lithium battery 2. A fire extinguishing system is arranged in the middle of the inner side of the protective housing 1, comprising a controller 3, and the controller 3 is connected to a fire detector assembly 9, a fire extinguishing assembly and a sealing assembly; The fire detector assembly 9 is distributed on the outer surface and the outer side of the lithium battery 2; the fire extinguishing assembly includes a fire extinguishing tank 4, which is connected to a plurality of fire extinguishing agent nozzles 6 through a delivery pipe 5, and the fire extinguishing agent nozzles 6 are arranged in the middle of the upper end of the lithium battery 2, and a plurality of fire extinguishing agent nozzles 7 are equidistantly installed in the middle of the bottom end of the fire extinguishing agent nozzle 6; the sealing assembly includes a plurality of sealing plates 11, and the sealing plates 11 are used to seal and cover the outer side of the protective shell 1. Driving assemblies are arranged at both ends of the sealing plate 11, and the driving assemblies are used to drive the sealing plate 11 to perform lifting and lowering movements.
[0017] Among them, the fire detector component 9 can be used to detect the fire situation inside the protective shell 1 in real time. When the controller 3 receives a fire signal, it will immediately start the fire extinguishing component to extinguish the fire. At the same time, the sealing component will be started to cover and seal the air vents 10 of the shell to reduce air circulation and prevent the fire from spreading.
[0018] The driving assembly includes two groups of chains 13, which are respectively arranged at the middle of both ends of the sealing plate 11. A connecting plate 12 is arranged in the middle of both ends of the sealing plate 11, and the connecting plate 12 is fixedly connected to the chain 13. A sprocket 14 is arranged in the middle of both ends of the chain 13, and the sprocket 14 is driven to rotate by a driving motor 15.
[0019] The sprocket 14 is driven to rotate by the driving motor 15, thereby driving the chain 13 to rotate. The rotation of the chain 13 can drive multiple sets of sealing plates 11 to move up and down, thereby covering and sealing the air holes 10 of the shell or opening them for ventilation.
[0020] A limiting slide groove 16 is provided in the middle of both ends of the sealing plate 11. The limiting slide groove 16 is installed on the inner side of the protective shell 1 and is located in the middle of both ends of the shell air vent 10. The connecting plate 12 is slidably installed in the inner middle of the limiting slide groove 16. The setting of the limiting slide groove 16 limits the sliding of the connecting plate 12, thereby preventing the sealing plate 11 from shifting and failing to accurately cover and seal the shell air vent 10.
[0021] In some examples, a sound and light alarm 17 is installed on the top of the protective shell 1, and the sound and light alarm 17 is electrically connected to the controller 3. When the controller 3 receives a fire signal, the sound and light alarm 17 is activated to warn.
[0022] In some examples, the fire detector assembly 9 includes a smoke detector, a temperature detector, and a combustible gas detector; wherein the temperature detector is mounted on the outer surface of the lithium battery 2 .
[0023] In some examples, multiple groups of fire extinguishing agent nozzles 6 are suspended and installed on the inner top of the protective shell 1, and the inlet ends of the multiple groups of fire extinguishing agent nozzles 6 are correspondingly provided with solenoid valves 8, which are controlled to open by the controller 3.
[0024] In some examples, a pressurizing drive module is pre-installed inside the fire extinguisher tank 4, and the fire extinguishing agent in the tank is stored in liquid form, so that the fire extinguisher tank 4 is "zero" pressure during transportation, installation, and operation, and is safe and risk-free.
[0025] In some examples, the present invention uses perfluorohexanone fire extinguishing agent, which vaporizes rapidly when heated, and takes away a large amount of heat through the strong thermal motion of molecules. The flame temperature drops from 150°C to 20°C within 2S, achieving the effect of rapid cooling; at the same time, it has the function of capturing free radicals and inhibiting the chemical chain reaction that causes the spread of flames, thereby preventing the development of fire. The fire extinguishing agent can be completely vaporized after spraying, and has the advantages of no stains, no traces, no color or taste, no damage to electronic components, and no need for cleaning.
[0026] The working principle of the present invention is: The lithium battery 2 is detected by the fire detector assembly 9. When a fire is detected in the lithium battery 2, the fire detector assembly 9 transmits the fire signal to the controller 3 for processing. The controller 3 controls the fire extinguishing tank 4 to open. The fire extinguishing agent in the fire extinguishing tank 4 is driven by the internal pre-installed boost drive module to be transported outward to the fire extinguishing agent nozzle 6, and finally sprayed out through the fire extinguishing agent nozzle 7 at the bottom, thereby realizing the fire extinguishing of the lithium battery 2; At the same time, when receiving a fire signal, the controller 3 sends a start command to the drive motor 15, and the drive motor 15 drives the sprocket 14 to rotate, thereby driving the chain 13 to rotate. When the chain 13 rotates counterclockwise, it can drive multiple sets of sealing plates 11 to slide down. When the sealing plates 11 and the air holes 10 of the shell are in an overlapping state, the air holes 10 of the shell can be covered and sealed, and the internal air of the protective shell 1 is isolated from the external air. Without the combustion-supporting oxygen, with the help of the fire extinguishing agent, the efficiency of fire extinguishing is further improved. In addition, the controller 3 will also control the sound and light alarm 17 to start, which serves as an alarm for the staff and reminds the staff to escape to avoid injury.
[0027] In addition, by providing a solenoid valve 8 at the inlet end of the fire extinguishing agent nozzle 6, when a fire occurs, the fire detector assembly 9 will locate the location of the fire, so that the controller 3 can fully open the solenoid valve 8 at the inlet end of the fire extinguishing agent nozzle 6 above the fire, while the solenoid valves 8 at other positions are half opened for flow limiting, so that the fire extinguishing agent can be sprayed on the fire point for fire extinguishing, achieving precise fire extinguishing, avoiding the consumption of the fire extinguishing agent at other positions, resulting in insufficient fire extinguishing agent in the end, and the fire cannot be completely extinguished; During the fire extinguishing process, the solenoid valves 8 at other positions can be gradually fully opened to spray and extinguish the lithium battery 2 in all directions, thereby effectively preventing the fire from reigniting.
[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
