Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent. Background Technology

[0002] Stacked energy storage cabinets save floor space by vertically stacking multiple lithium battery boxes. However, when a cell in a battery box experiences thermal runaway, fire and high temperature can easily spread rapidly between the sealed and closely adjacent boxes, causing the entire energy storage system to fail or even triggering a serious fire.

[0003] Traditional external fire suppression methods require the extinguishing agent to penetrate the external barrier of the cabinet to reach the internal fire source. In stacked structures, flames and high temperatures in the upper battery compartments tend to spread upwards, severely hindering the effective delivery of the extinguishing agent to the lower ignition points.

[0004] Patent CN121035491A discloses a lithium-ion battery energy storage cabinet with fire extinguishing function and its usage method. The above patent achieves extremely high safety and reliability. When the fire detection unit issues an early warning, the fire extinguishing agent is sprayed to the fire point through the fire extinguishing agent release pipeline and nozzle to quickly extinguish the open flame.

[0005] The aforementioned patent continuously cools the high-temperature battery module through atomizing nozzles, solving the problem of lithium-ion batteries being prone to reignition.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 One embodiment of the present invention provides a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent, comprising an upper box 1, wherein a fire extinguisher 3 and a water tank 4 are placed in the upper box 1. A primary solenoid valve 8 is provided on the side wall of the fire extinguisher 3, and a fire-fighting pipe 9 is provided on the side wall of the primary solenoid valve 8. A first connector 10 is fixedly installed on the side wall of the fire-fighting pipe 9, and a primary pipe 6 is fixedly installed on the side wall of the first connector 10. A secondary solenoid valve 5 is fixedly connected to the side wall of the primary pipe 6, and a secondary pipe 7 is fixedly connected to the side wall of the secondary solenoid valve 5. A second connector 14 is fixedly installed on the side wall of the secondary pipe 7. The second connector 14 is fixedly connected to the side wall of the battery box 2, and the second connector 14 is fixedly connected to the side wall of the fire extinguishing pipe 15. The water storage tank 4 is connected to the circulation pump 11 through a pipe. The circulation pump 11 is fixedly connected to the side wall of the outlet pipe 12, and the outlet pipe 12 is fixedly connected to the side wall of the circulation pipe 17. The secondary solenoid valve 5 is fixedly connected to the side wall of the upper box 1. The water storage tank 4 is fixedly connected to the side wall of the connecting pipe 13. The circulation pump 11 is fixedly connected to the side wall of the connecting pipe 13. The connecting pipe 13 and the outlet pipe 12 pass through the battery box 2. The second connector 14 is fixedly connected to the side wall of the battery box 2, and the first connector 10 is fixedly connected to the side wall of the upper box 1.

[0036] Furthermore, the fire extinguisher 3 is a steel cylinder containing a non-chemical plant-based extinguishing agent. The fire extinguisher 3 is located in the uppermost compartment 1 of the stacked energy storage cabinet, with battery boxes 2 stacked sequentially. The fire extinguisher 3 is placed on top of the uppermost battery box 2. When a battery pack 16 in a battery box 2 begins to experience thermal runaway due to an internal short circuit or other reasons, the temperature of the battery pack 16 rises sharply, possibly accompanied by smoke. After the temperature sensor or smoke detector located in the battery box 2 detects the abnormal signal, it is transmitted to the control host 29. The control host 29 immediately issues a command to open the primary solenoid valve 8 at the outlet of the fire extinguisher 3. Simultaneously, according to the... At the location where the abnormal signal is sent, only the secondary solenoid valve 5 of the branch circuit where the burning battery box 2 is located is opened, so that the secondary pipeline 7 of the branch circuit where the burning battery box 2 is located is connected to the primary pipeline 6. The compressed non-chemical plant-based fire extinguishing agent in the fire extinguisher 3 cylinders, driven by its own pressure, flows through the already opened primary solenoid valve 8, sequentially through the fire pipeline 9, the first connector 10, and the primary pipeline 6, and then through the secondary solenoid valve 5 to the secondary pipeline 7 and the second connector 14 of the target battery box 2. The fire extinguishing agent is sprayed out at high speed from the nozzle of the fire extinguishing pipeline 15 that extends into the battery box 2, covering the battery cell that is opening or about to open the explosion-proof pressure relief valve, thereby extinguishing the fire.

[0037] During normal operation, the control unit 29 starts the circulation pump 11, which pumps cold water from the storage tank 4 into the outlet pipe 12. The cold water passes through the outlet pipe 12 and the circulation pipe 17, absorbing heat, and then returns to the storage tank 4 through the connecting pipe 13. A cooling unit such as a fan-cooled radiator can be installed on the connecting pipe 13, allowing the warm water in the connecting pipe 13 to dissipate heat to the outside air of the energy storage cabinet. The cooled water then returns to the storage tank 4. Thus, when the temperature of the battery pack 16 in the battery box 2 continuously exceeds the preset safety threshold due to normal operating heat generation, but is far from reaching the level of thermal runaway or triggering the smoke detector, the water is cooled by the circulation pipe 17, etc. The system enables preventative cooling, intervening before a fire occurs to bring the temperature of battery pack 16 back to a safe range, preventing thermal runaway. It also keeps battery pack 16 operating within its optimal temperature range, thus extending battery cycle life. Upon detection of open flames, large amounts of smoke, or a rapid temperature spike, extinguishing agents are sprayed through fire extinguisher 3, primary battery valve 8, and secondary battery valve 5 to cool and extinguish the fire. Simultaneously, cold water flows through the entire energy storage cabinet via circulation pipe 17 and other structures, absorbing heat from the surrounding battery pack 16 that is not directly on fire but is being baked by the high temperature, preventing heat spread and reducing the risk of reignition. This enhances the stacked energy storage cabinet's ability to cope with battery thermal runaway accidents.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7An embodiment of the present invention provides a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent, comprising an upper cabinet 1 and a battery cabinet 2. The upper cabinet 1 is equipped with a fire extinguisher 3, a water storage tank 4, a primary battery valve 8, a fire-fighting pipe 9, a first connector 10, a primary pipe 6, a secondary pipe 7, a secondary battery valve 5, and a circulation pump 11. The battery cabinet 2 is equipped with a second connector 14, a fire extinguishing pipeline 15, a circulation pipe 17, a connecting pipe 13, and a water outlet pipe 12. The bottom of the outer wall of the circulation pipe 17 has an opening groove 27, a sealing ring gasket 24 is fixedly connected to the outer wall of the circulation pipe 17, a protective shell 18 is fixedly connected to the outer wall of the sealing ring gasket 24, an outflow groove 26 is opened at the bottom of the outer wall of the protective shell 18, and the battery cabinet 2 is fixedly connected to the top of the outer wall of the protective shell 18. The outflow groove 26 is located directly below the opening groove 27.

[0039] Furthermore, the sealing ring gasket 24 is made of a low-temperature melting material, such as plastic with a specific melting point. It has sealing properties at room temperature, but it will quickly soften, melt, or rupture under the high temperature generated by the flame. When the battery pack 16 inside the battery box 2 continues to heat up and produces an open flame, the sealing ring gasket 24 on the outside of the circulation pipe 17 above the burning battery pack 16 will rupture under the action of the flame. The ruptured sealing ring gasket 24 will no longer block the opening groove 27, allowing the water in the circulation pipe 17 to fall into the protective shell 18 through the opening groove 27, and then fall onto the battery box 2 through the outflow groove 26 at the bottom of the protective shell 18, forming a water curtain coverage. This effectively prevents the spread of high temperature and flame to adjacent battery boxes 2, avoiding the escalation of the accident. Moreover, the water will absorb a large amount of heat after contacting the flame, lowering the temperature and destroying the combustion conditions. The extinguishing agent in the fire extinguisher 3 passes through the fire pipe 9, the first connector 10, and the first... The primary pipeline 6, through the secondary battery valve 5, flows to the secondary pipeline 7, the second connector 14, and the fire extinguishing pipeline 15 of the burning battery box 2, spraying out the extinguishing agent to extinguish the fire. By setting up structures such as the sealing ring gasket 24, it is triggered when an open flame appears, preventing the spread of the fire and thus providing more time for the entire extinguishing process of the extinguishing agent. This prevents the fire from being too large and the sprayed extinguishing agent from being insufficient to extinguish the fire quickly, causing the fire to spread to adjacent battery boxes 2. The dual protection of the passive water curtain structure such as the sealing ring gasket 24 and the active fire extinguishing structure such as the fire extinguisher 3 achieves rapid and reliable fire control, creating the best conditions for the extinguishing agent to extinguish the fire, and further enhancing the ability of the stacked energy storage cabinet to cope with battery thermal runaway accidents. The protective shell 18 can protect the sealing ring gasket 24, preventing external forces from damaging the sealing ring gasket 24 and causing the sealing ring gasket 24 to break prematurely.

[0040] Please see Figure 3 , Figure 4 , Figure 5 and Figure 7One embodiment of the present invention provides a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent. The upper cabinet 1 is equipped with a fire extinguisher 3, a water tank 4, a primary solenoid valve 8, a fire-fighting pipe 9, a first connector 10, a primary pipe 6, a secondary pipe 7, a secondary solenoid valve 5, a circulation pump 11, a battery box 2, a second connector 14, a fire extinguishing pipeline 15, a circulation pipe 17, a connecting pipe 13, and a water outlet pipe 12. The bottom of the outer wall of the circulation pipe 17 has an opening groove 27. A sealing ring gasket 24 is fixedly connected to the outer wall of the 7. A protective shell 18 is fixedly connected to the outer wall of the sealing ring gasket 24. An outflow groove 26 is opened at the bottom of the outer wall of the protective shell 18. A battery box 2 is fixedly connected to the top of the outer wall of the protective shell 18. A connecting frame 19 is fixedly connected to the bottom of the outer wall of the battery box 2. A flow-blocking block 20 is fixedly connected to the bottom of the outer wall of the connecting frame 19. A trapezoidal groove 28 is opened on the side wall of the flow-blocking block 20. A connecting groove 21 is opened on the side wall of the flow-blocking block 20. The flow-blocking block 20 is located directly below the outflow groove 26.

[0041] Furthermore, when the battery pack 16 inside the battery box 2 continues to heat up due to thermal runaway or other reasons, and the temperature reaches a certain threshold, a thermal runaway reaction occurs inside the battery, generating open flames and high-temperature gases. The sealing ring gasket 24 above the burning battery pack 16 ruptures under the high temperature of the flame. The ruptured sealing ring gasket 24 no longer seals the opening slot 27 at the bottom of the circulation pipe 17. The water in the circulation pipe 17 falls into the protective shell 18 through the opening slot 27 and continues to fall through the outflow slot 26. Before the water falls into the battery box 2, it first falls onto the baffle block 20 and then into the trapezoidal slot 28 of the baffle block 20. Under the action of the trapezoidal slot 28, the water is evenly distributed. The water is directed to the perimeter of the baffle block 20. As the water accumulates on the trapezoidal groove 28, the water level in the trapezoidal groove 28 gradually rises. When the water level is higher than the trapezoidal groove 28, the water falls through the connecting groove 21, thereby evenly guiding the outflowing water to the perimeter of the battery pack 16. This transforms the concentrated single stream of water into a uniform, continuous, and complete water curtain surrounding the battery pack 16, preventing the local sealing ring gasket 24 from breaking and thus ensuring a uniform water curtain around the battery pack 16. This prevents the water curtain from failing to form a complete isolation ring, ensuring uniform coverage, improving the effect of preventing the spread of fire, and solving the problem that local drainage cannot form effective protection.

[0042] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7One embodiment of the present invention provides a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent. The outer wall of the protective shell 18 is movably fitted with a displacement ring 39. A connecting block 40 is connected to the side wall of the displacement ring 39. A connecting piece 25 is fixedly connected to the side wall of the connecting block 40. A sealing ring gasket 24 is fixedly connected to the side wall of the connecting piece 25. A fireproof strip 23 is fixedly connected to the side wall of the displacement ring 39. A coil spring mechanism 22 is fixedly connected to the side wall of the fireproof strip 23. A battery box 2 is fixedly connected to the side wall of the coil spring mechanism 22. A locking block 30 is fixedly connected to the side wall of the fireproof strip 23. A fixed frame 38 is fixedly connected to the bottom of the outer wall of the box 2. A fixed cylinder 36 is fixedly connected to the side wall of the fixed frame 38. A piston plate 37 is movably fitted inside the fixed cylinder 36. A movable rod 35 is fixedly connected to the side wall of the piston plate 37. A movable plate 33 is fixedly connected to the side wall of the movable rod 35. A symmetrical plate 34 is symmetrically fixedly connected to the side wall of the movable plate 33. An abutment plate 32 is fixedly fixedly connected to the side wall of the symmetrical plate 34. The abutment plates 32 are symmetrically arranged on both sides of the fireproof strip 23. A first airbag 41 is fixedly connected to the inner wall of the fixed cylinder 36. A positioning block 31 is movably fitted to the outer wall of the locking block 30.

[0043] Furthermore, when the battery pack 16 inside the battery box 2 generates open flames and high-temperature gases, the temperature inside the burning battery box 2 continues to rise, causing the gas temperature in the sealed space inside the fixed cylinder 36 above the burning battery pack 16 to gradually increase. The gas in the sealed space inside the first airbag 41 on the fixed cylinder 36 expands due to heat, causing the first airbag 41 to expand. This first airbag 41 then pushes the piston plate 37 inside the fixed cylinder 36. The piston plate 37 drives the movable rod 35 to move, which in turn drives the movable plate 33 to move, causing the movable plate 33 to gradually approach the fireproof strip 23. Plate 33 drives symmetrical plate 34 to move, and symmetrical plate 34 drives abutment plate 32 to move, causing abutment plate 32 to gradually move away from locking block 30. The contact area between abutment plate 32 and locking block 30 gradually decreases. When the two abutment plates 32 are no longer in contact with locking block 30, the abutment plates 32 no longer abut against locking block 30. The elastic potential energy stored in the coiling spring mechanism 22 drives fireproof strip 23 to rewind through torque. Fireproof strip 23 drives displacement ring 39 to move, displacement ring 39 drives connecting block 40 to move within outflow groove 26, and connecting block 40 drives connecting piece 25. The connecting piece 25 pulls on the sealing ring gasket 24, thereby forcibly tearing or pulling off the sealing ring gasket 24. Simultaneously, as the sealing ring gasket 24 above the burning battery pack 16 partially ruptures under the high temperature of the flame, the connecting piece 25 further ruptures it, allowing more openings 27 to connect with the outflow groove 26. This causes a large amount of water to flow out of the circulation pipe 17, accelerating the outflow speed. A large amount of water falls onto the baffle block 20 and quickly distributes around the trapezoidal groove 28. By accelerating the accumulation of water on the trapezoidal groove 28, the water... The water flows out quickly from the trapezoidal groove 28, thus quickly and timely forming a complete water curtain around the battery pack 16, further preventing the spread of fire and avoiding the problem of fire spreading due to the inability of the water curtain to form in time; before the locking block 30 moves, the locking block 30 contacts the positioning block 31, and the abutment plate 32 abuts the locking block 30. The positioning block 31 is fitted on one side of the locking block 30 to fix the side of the locking block 30 that is not connected to the fireproof strip 23, so as to prevent the abutment plate 32 from moving while driving the locking block 30 to move, causing the abutment plate 32 to continuously abut the locking block 30.

[0044] Please see Figure 3 , Figure 4 , Figure 6 and Figure 8 An embodiment of the present invention provides: a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent, wherein the battery box 2 is provided with a displacement ring 39, a connecting block 40, a fireproof strip 23, a coil spring mechanism 22, a fixing frame 38, a piston plate 37, a movable rod 35, a symmetry plate 34, a contact plate 32, a moving plate 33, and a first airbag 41; a second airbag 42 is fixedly connected to the side wall of the first airbag 41, a fixing cylinder 36 is fixedly connected to the side wall of the second airbag 42, a spike 43 is fixedly connected to the inner wall of the fixing cylinder 36, and a self-expanding substance 44 is provided inside the second airbag 42.

[0045] Furthermore, the battery pack 16 inside the battery box 2 generates an open flame, causing a fire. The temperature inside the battery box 2 continues to rise, causing the gas in the sealed space of the first airbag 41 in the fixed cylinder 36 above the battery pack 16 to expand due to heat. The expansion of the first airbag 41 pushes the piston plate 37 inside the fixed cylinder 36. The expansion of the first airbag 41 pushes the second airbag 42, causing the second airbag 42 to gradually approach and squeeze the spike 43. When the spike 43 punctures the second airbag 42, the self-expanding substance 44 inside the second airbag 42 overflows. The self-expanding substance 44 expands after contacting the air inside the fixed cylinder 36, thereby squeezing the first airbag 41. This causes the first airbag 41 to further squeeze and push the piston plate 37, thus pushing the piston plate 37 further. The piston plate 37 drives the movable rod 3. 5. When the movable plate 33, symmetrical plate 34, and abutting plate 32 no longer abut against the locking block 30, the coil spring mechanism 22 drives the fireproof belt 23 to rewind. The fireproof belt 23 drives the displacement ring 39, connecting block 40, and connecting piece 25. The connecting piece 25 pulls the sealing ring gasket 24, causing the sealing ring gasket 24 to rupture. The water in the circulation pipe 17 flows out through the opening groove 27 and the outflow groove 26. By setting the second airbag 42, self-expanding substance 44, and spike 43, when the second airbag 42 is squeezed and ruptured, the self-expanding substance 44 overflows and expands rapidly, generating additional pressure. It can generate huge thrust in an instant, further squeezing the first airbag 41, ensuring that the piston plate 37, abutting plate 32, and other structures have sufficient stroke, and ensuring that the abutting plate 32 releases its fixation on the locking block 30.

[0046] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An embodiment of the present invention provides: a stacked energy storage cabinet with a non-chemical plant-based fire extinguishing agent, wherein the upper cabinet 1 is provided with a fire extinguisher 3, a water storage tank 4, a primary solenoid valve 8, a fire pipe 9, a first connector 10, a primary pipe 6, a secondary pipe 7, a secondary solenoid valve 5, a circulation pump 11, a battery box 2, a second connector 14, a fire extinguishing pipeline 15, a circulation pipe 17, a connecting pipe 13, and a water outlet pipe 12; the circulation pipe 17 is provided with an opening groove 27, a sealing ring gasket 24, and a protective shell 18; the flow deflector 20 is provided with a trapezoidal groove 28 and a connecting groove 21; the battery box 2 is provided with a displacement ring 39, a connecting block 40, a fireproof strip 23, a coil spring mechanism 22, a fixing frame 38, a piston plate 37, a movable rod 35, a symmetrical plate 34, a contact plate 32, a moving plate 33, a first airbag 41, and a fixing cylinder 36; the side wall of the battery box 2 is detachably connected to a push plate 45.

[0047] Furthermore, when the battery pack 16 inside the battery box 2 generates open flames and high-temperature gases, the partial sealing ring gasket 24 above the burning battery pack 16 ruptures under the high temperature of the flames. At the same time, the open flames and high-temperature gases cause the temperature inside the burning battery box 2 to continue to rise, causing the first airbag 41 inside the fixed cylinder 36 above the burning battery pack 16 to expand. The first airbag 41 pushes the piston plate 37 inside the fixed cylinder 36. The piston plate 37 drives the movable rod 35, the moving plate 33, the symmetrical plate 34, and the abutment plate 32 to move, so that the abutment plate 32 no longer abuts the locking block 30. The coil spring mechanism 22 drives the fireproof strip 23, the connecting block 40, and the connecting piece 25. The connecting piece 25 tears the sealing ring gasket 24. When the flame directly burns the sealing ring gasket 24 at a certain position, causing part of the sealing ring gasket 24 to initially rupture, the flames cause the entire battery box 2 to heat up. By setting multiple coil spring mechanisms 22 and fixed frames, Structures such as 38 and 36 can further tear the sealing ring gasket 24 around the broken position, and tear the other intact sealing ring gaskets 24, so that the opening slots 27 at various positions on the circulation pipe 17 are opened, and the water in the circulation pipe 17 flows out further, forming an annular water curtain around the battery pack 16; the connecting pipe 13 and the water outlet pipe 12 include their respective pipes and quick connectors. When it is necessary to move the stacked upper box 1 and battery box 2, the push plate 45 on the battery box 2 is moved to open the operation window on the battery box 2. At this time, the battery box 2 can be inserted to operate the connecting pipe 13 and the water outlet pipe 12 inside the battery box 2. By pressing and other actions, the quick connectors are operated to separate the pipes and quick connectors. The connecting pipe 13 and the water outlet pipe 12 of the upper and lower battery boxes 2 are separated, and the secondary pipe 7 and the second connector 14 are further separated. At this time, the battery box 2 can be moved.

[0048] Working principle: When the battery pack 16 in the battery box 2 produces an open flame, the sealing ring gasket 24 breaks under the high temperature of the flame, and the opening groove 27 is connected to the outflow groove 26. The water in the circulation pipe 17 flows out and falls onto the baffle block 20. It is evenly distributed to the perimeter of the baffle block 20 through the trapezoidal groove 28. After the water overflows from the trapezoidal groove 28, it falls through the connecting groove 21, forming a water curtain around the battery pack 16 to suppress the spread of fire.

[0049] The first airbag 41 inside the fixed cylinder 36 expands due to heat. The first airbag 41 drives the piston plate 37, the movable rod 35, the moving plate 33, the symmetrical plate 34, and the abutment plate 32 to move. When the abutment plate 32 no longer abuts the locking block 30, the coil spring mechanism 22 drives the fireproof strip 23, the connecting block 40, and the connecting piece 25. The connecting piece 25 tears the sealing ring gasket 24, causing the sealing ring gasket 24 to break further, and further causing the water in the circulation pipe 17 to flow out.

[0050] When the secondary solenoid valve 5 and the primary solenoid valve 8 are opened, the extinguishing agent in the fire extinguisher 3 flows through the fire pipe 9, the first connector 10, and the primary pipe 6, and through the secondary solenoid valve 5 to the secondary pipe 7, the second connector 14, and the fire extinguishing pipe 15 of the burning battery box 2. The nozzle of the fire extinguishing pipe 15 sprays out the extinguishing agent to extinguish the fire.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
