Abstract
Description
Technical Field
[0001] This application relates to the field of fire-fighting equipment technology, and in particular to a Pack-level fire suppression device. Background Technology
[0002] Risk control of batteries in energy storage power stations has become a key public safety concern. Fire suppression devices within battery packs can prolong thermal runaway and protect property. Compared to extinguishing agents such as hexafluoropropane and aerosols, perfluorohexanone, as an inhibitor in fire suppression devices, has advantages such as low extinguishing concentration, high extinguishing efficiency, high safety factor, non-conductivity, no residue, and environmental friendliness.
[0003] Most existing energy storage pack-level fire suppression devices are vertical pressure storage devices, which have limitations in installation layout. Furthermore, due to the vertical installation and the concave structure at the bottom of the pressure storage bottle, the suppressant inside the bottle is completely discharged, resulting in serious waste. In addition, the fire suppression device is poorly fixed inside the battery pack, and it may collide with the battery pack due to shaking when the suppressant is released, posing a safety hazard. Utility Model Content
[0004] In view of this, this application provides a Pack-level fire suppression device that can extinguish fires within the battery pack, effectively reducing agent residue, increasing the efficiency of the fire suppression device, and reducing the radial and axial forces generated by the horizontal storage cylinder during the vaporization of the suppressant, preventing collisions with the battery pack and eliminating safety hazards.
[0005] Specifically, the following technical solutions are included:
[0006] This application provides a Pack-level fire suppression device, which includes a horizontal pressure storage bottle, a bottle head valve body, a liquid outlet pipe, a horizontal siphon pipe, a lower shell, an upper cover, a fixing plate, and multiple saddle clamps;
[0007] The bottle head valve body is installed at the mouth of the horizontal storage bottle and has a release port. The release port and the liquid outlet pipe located on the bottle head valve body are connected to the interior of the horizontal siphon tube located inside the horizontal storage bottle. The horizontal siphon tube includes a vertical part and a bent part. The vertical part is perpendicular to the side of the lower shell near the mouth of the horizontal storage bottle. The bent part has a horizontal cut at the end away from the vertical part, extending to the bottom of the horizontal storage bottle. The liquid outlet pipe has a liquid outlet.
[0008] The horizontal pressure storage bottle is placed in the space formed by the lower shell and the upper cover. The lower shell has an opening on the side near the bottle mouth of the horizontal pressure storage bottle so that the liquid outlet tube can pass through.
[0009] The fixing plate includes fixing part one and fixing part two. Fixing part one is fixedly connected to one side of the lower shell. The saddle clip is fastened to the body of the horizontal pressure storage bottle and is fixedly connected to fixing part one.
[0010] In some embodiments, the length of the vertical portion accounts for 40-50% of the height of the horizontal pressure storage bottle, and the bending angle of the bent portion is 120-150°.
[0011] In some embodiments, the fire suppression device is mounted below the battery pack.
[0012] In some embodiments, the bottle head valve body further includes a filling port and a drain port.
[0013] In some embodiments, the fire suppression device further includes a safety relief valve and a release adapter, wherein the safety relief valve is located at the relief port and the release adapter is located at the release interface.
[0014] In some embodiments, the fire suppression device further includes a start driver mounted on the bottle head valve body.
[0015] In some embodiments, the fire suppression device further includes a PCB control board, a communication interface, and a pressure feedback module mounted on the bottle head valve body.
[0016] In some embodiments, the fire suppression device further includes a push-pull handle disposed on the side of the lower housing near the bottle opening of the horizontal pressure storage bottle.
[0017] In some embodiments, the fire suppression device further includes a plurality of fixing lugs located on the lower housing.
[0018] In some embodiments, the fire suppression device further includes a waterproof and breathable valve installed on the side of the lower housing near the bottle opening of the horizontal pressure storage bottle, the waterproof and breathable valve communicating with the space formed by the lower housing and the upper cover.
[0019] The beneficial effects of the technical solutions provided in this application include at least the following:
[0020] This application provides a Pack-level fire suppression device. During use, because the internal pressure of the horizontal storage cylinder is greater than the external pressure, the liquid suppressant flows through the bend in the horizontal siphon tube, through the vertical section, and reaches the outlet pipe on the cylinder head valve. Finally, it vaporizes and releases from the outlet of the outlet pipe, thus extinguishing a fire in the battery pack. Because the horizontal siphon tube has a bend with a horizontal cut, a negative pressure is created at the outlet as the liquid suppressant flows through the horizontal siphon tube, further propelling the liquid suppressant to continue flowing until it is exhausted, effectively reducing residue and increasing the efficiency of the fire suppression device. During the vaporization of the suppressant, the fixing part one of the fixing plate cooperates with multiple saddle clips to reduce the radial force generated by the vaporization of the suppressant in the horizontal storage cylinder, and the fixing part two reduces the axial force generated by the vaporization of the suppressant in the horizontal storage cylinder, thereby limiting and fixing the horizontal storage cylinder, preventing collisions with the battery pack, and eliminating safety hazards.

Detailed Implementation
[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] This application provides a Pack-level fire suppression device, see [link to relevant documentation] Figures 1 to 3 The fire suppression device includes a horizontal pressure storage bottle 1, a bottle head valve body 2, an outlet pipe 3, a horizontal siphon pipe 4, a lower shell 5, an upper cover 6, a fixing plate 7, and multiple saddle clamps 8.
[0029] The bottle head valve body 2 is installed at the mouth of the horizontal storage bottle 1 and has a release interface. The release interface and the liquid outlet pipe 3 located on the bottle head valve body 2 are connected to the interior of the horizontal siphon pipe 4 located inside the horizontal storage bottle 1. The horizontal siphon pipe 4 includes a vertical part 41 and a bent part 42. The vertical part 41 is perpendicular to the side of the lower housing 5 near the mouth of the horizontal storage bottle 1. The bent part 42 has a horizontal cut 421 at the end away from the vertical part 41, which extends to the bottom of the horizontal storage bottle 1. The liquid outlet pipe 3 has a liquid outlet 31.
[0030] The valve body 2 is a key component connecting the horizontal storage bottle 1 to the outside world. The release port of the valve body 2 connects the outlet pipe 3 located on the valve body 2 outside the horizontal storage bottle 1 to the interior of the horizontal siphon pipe 4 inside the bottle. The horizontal siphon pipe 4, the release port, and the outlet pipe 3 provide a release channel for the inhibitor, thus ensuring successful vaporization of the inhibitor. The horizontal siphon pipe 4, including a bend 42 extending to the bottom of the horizontal storage bottle 1 with a horizontal cut 421, can fit snugly against the bottom of the bottle 1, thereby completely discharging the inhibitor, avoiding waste due to inhibitor residue, and increasing the efficiency of the fire suppression device.
[0031] A horizontal pressure storage bottle 1 is placed in the space formed by the lower housing 5 and the upper cover 6. The lower housing 5 has an opening near the bottle neck of the horizontal pressure storage bottle 1 for the outlet pipe 3 to pass through. The space formed by the lower housing 5 and the upper cover 6 provides installation space for the horizontal pressure storage bottle 1, facilitating its installation within the battery pack. It also provides a certain degree of gas barrier, preventing mutual interference between the battery and the horizontal pressure storage bottle 1, and preventing the direct adhesion of the vaporized inhibitor to internal components, ensuring the normal release of the inhibitor. The opening near the bottle neck of the lower housing 5 for the outlet pipe 3 ensures that one end of the outlet pipe 3 is located within the space formed by the lower housing 5 and the upper cover 6, while the other end exits through the opening in the lower housing 5, allowing the inhibitor to be released outside the space formed by the lower housing 5 and the upper cover 6. The horizontal structure of the horizontal pressure storage bottle 1 effectively matches the length dimensions of a battery pack, facilitating battery pack layout.
[0032] The fixing plate 7 includes a fixing part 1 71 and a fixing part 2 72. The fixing part 1 71 is fixedly connected to one side of the lower housing 5. The saddle clips 8 are fastened to the body of the horizontal pressure storage bottle 1 and are fixedly connected to the fixing part 1 71. The fixing part 1 71 of the fixing plate 7 cooperates with multiple saddle clips 8 to reduce the radial force generated by the suppression of drug vaporization in the horizontal pressure storage bottle 1. The fixing part 2 72 reduces the axial force generated by the suppression of drug vaporization in the horizontal pressure storage bottle 1, thereby achieving the limiting and fixing of the horizontal pressure storage bottle 1, preventing collision with the battery pack, and eliminating safety hazards.
[0033] See Figure 2 When this fire suppression device is in use, because the internal pressure of the horizontal storage cylinder is greater than the external pressure, the liquid suppressant can flow through the bend 42 of the horizontal siphon 4, through the vertical section 41, and reach the outlet pipe 3 on the cylinder head valve body 2. Finally, it vaporizes and is released from the outlet 31 of the outlet pipe 3, thus extinguishing the fire in the battery pack. Because the horizontal siphon 4 has a bend 42 with a horizontal cut 421, a negative pressure is formed at the outlet 31 when the liquid suppressant flows through the horizontal siphon 4, further... The liquid suppressant is continuously propelled until it is exhausted, thereby effectively reducing residue and increasing the efficiency of the fire suppression device. During the vaporization of the suppressant, the fixing part 71 of the fixing plate 7 cooperates with multiple saddle clips 8 to reduce the radial force generated by the vaporization of the suppressant in the horizontal pressure storage bottle 1, and the fixing part 72 reduces the axial force generated by the vaporization of the suppressant in the horizontal pressure storage bottle 1, thereby achieving the limiting and fixing of the horizontal pressure storage bottle 1, preventing collision with the battery pack and eliminating safety hazards.
[0034] In some embodiments, the length of the vertical portion 41 accounts for 40-50% of the height of the horizontal storage bottle 1, and the bending angle of the bent portion 42 is 120-150°. This configuration allows the inhibitor to be continuously vaporized and released from the horizontal storage bottle 1 using a siphon effect. This range of bending angles facilitates the installation of the horizontal siphon tube 4 and reduces pipeline resistance caused by pipeline bending during the initial start-up release of the inhibitor.
[0035] In some embodiments, the fire suppression device is installed below the battery pack. This arrangement allows the vaporized suppressant to extinguish the fire from top to bottom within the pack, achieving pack-level gas suppression.
[0036] In some embodiments, the inhibitor in the horizontal storage cylinder 1 can be perfluorohexanone, which has the characteristics of low extinguishing concentration, high extinguishing efficiency, high safety factor, non-conductivity, no residue and environmental protection.
[0037] In some embodiments, the lower housing 5 and the upper cover 6 can be fixedly connected by bolts.
[0038] In some embodiments, the lower housing 5 and the upper cover 6 may be foam-sealed to meet a high protection level.
[0039] In some embodiments, the bottle head valve body 2 also has a filling port 21 and a venting port 22. The filling port is used to replenish the suppressant after it is used up, and the venting port 22 facilitates immediate release of pressure in the horizontal storage bottle 1 in case of overpressure, thereby improving the safety of the fire suppression device.
[0040] In some embodiments, the bottle head valve body 2 and the horizontal pressure storage bottle 1 can be connected by threads, and the bottle head valve body 2, the horizontal pressure storage bottle 1 and other devices can form a sealed space.
[0041] In some embodiments, the fire suppression device further includes a safety relief valve 9 and a release adapter 10. The safety relief valve 9 is located at the relief port 22 to allow for timely overpressure relief through the safety relief valve 9. The release adapter 10 is located at the release interface to provide a release path for the suppressing agent from the release interface to the outlet pipe 3.
[0042] In some embodiments, the fire suppression device further includes a start driver 11, which is mounted on the bottle head valve body 2 and is used to receive control commands from the PCB control board 12 to control the opening and closing of the release interface, thereby releasing the suppressing agent as needed.
[0043] In some embodiments, the fire suppression device further includes a PCB control board 12, a communication interface 13, and a pressure feedback module 14 mounted on the bottle head valve body 2. The communication interface 13 is used for communication between the PCB control board 12 and other external terminals. The pressure feedback module 14 is used to detect the pressure inside the horizontal storage bottle 1 and transmit the pressure to the PCB control board 12. The PCB control board 12 is used to control the start-up driver 11 to control the opening and closing of the release interface; receive the pressure transmitted by the pressure feedback module 14; in response to a pressure exceeding a threshold pressure, issue an overpressure warning and control the opening of the safety relief valve 9 for overpressure relief; in response to a pressure below the threshold pressure, issue a reminder to add suppressant to remind the user to refill the suppressant in a timely manner; receive remote control from other external terminals to promptly control the release of suppressant when a fire occurs in the battery; and send the real-time operating status of the fire suppression device to other external terminals to ensure the safe and stable operation of the fire suppression device.
[0044] In some embodiments, the PCB control board 12 may be located inside the lower housing 5 near the bottom of the horizontal storage bottle 1, thereby keeping it away from the environment where the inhibitor releases, so as to prevent the vaporization of the inhibitor from affecting the stable operation of the PCB control board 12.
[0045] In some embodiments, the fire suppression device further includes a push-pull handle 15 disposed on the side of the lower housing 5 near the bottle neck of the horizontal pressure storage bottle 1, and a plurality of fixed hooks 16 located on the lower housing 5. The push-pull handle 15 allows the user to install and remove the fire suppression device, enabling horizontal pull-out installation and removal. The fixed hooks 16 are used to secure the fire suppression device within the battery pack.
[0046] See Figure 3 In some embodiments, the fire suppression device also includes a waterproof and breathable valve 17 installed on the side of the lower housing 5 near the bottle opening of the horizontal pressure storage bottle 1. The waterproof and breathable valve 17 communicates with the space formed by the lower housing 5 and the upper cover 6, thereby realizing the air pressure balance inside and outside the space and the emergency high pressure release function.
[0047] In some embodiments, the horizontal pressure storage bottle 1 may be made of stainless steel to provide it with sealing, pressure resistance and corrosion resistance.
[0048] In summary, the Pack-level fire suppression device provided in this application embodiment can extinguish fires within the battery pack, effectively reduce agent residue, increase the efficiency of the fire suppression device, and reduce the radial and axial forces generated by the horizontal storage bottle during the vaporization of the suppressant, preventing collisions with the battery pack and eliminating safety hazards.
