The cylinder 1 serves as a power source, drives the push rod 4 to quickly eject the battery pack 6 from the battery cabin. In the embodiment, the force receiving unit includes a square support point 9.
[0031] Specifically, as shown in Figure 4 The cylinder 1 includes a cylinder rod 2 and a cylinder barrel 3.

The two ends of the inclined rod are respectively connected with one end of the two straight rods, for example, the inclined rod and the straight rod are fixed by welding. The two straight rods are parallel to each other, so that the movement trajectory of the push rod 4 is a straight line, thereby ensuring that the battery pack 6 can be smoothly and linearly ejected from the battery cabin. The two straight rods transmit the thrust of the cylinder 1 to the inclined rod, and the inclined rod uniformly distributes the thrust to the battery pack 6, thereby smoothly pushing the battery pack 6.

[0034] Please refer to Figures 1-3 In the embodiment, the conduction unit includes a pulley 5 and a pulley groove 8, and the pulley 5 is installed in the pulley groove 8. The pulley groove 8 provides accurate guidance for the pulley 5, so as to ensure the correct direction of the battery pack 6 during the ejection process.
[0035] As an example, the pulley 5 has a plurality of pulley strips, which can be better guided.
[0036] Further, a limiting member (not shown) is arranged at one end of the pulley strip inside the device, so that the pulley 5 strip does not come off the pulley groove 8. It can be understood that the limiting member is a prior art, which will not be described in detail here.
[0037] In addition, the ejection mechanism also includes a support column 7, and the pulley groove 8 is installed on the support column 7.

[0038] In application, the battery pack 6 is arranged on the pulley 5 and located at the front side of the push rod 4. When the air cylinder 1 works, the battery pack 6 can be smoothly ejected through the push rod 4.
[0039] The utility model also provides a kind of PACK level fire-fighting device for energy storage system, including above-mentioned battery pack ejection mechanism, still include battery cabin, hydraulic mechanism, fire-fighting detection mechanism, main control mechanism, liquid cooling mechanism and spraying mechanism.The hydraulic mechanism, the fire-fighting detection mechanism, the liquid cooling mechanism and the spraying mechanism are all connected with the main control mechanism.
[0040] Specifically, the battery cabin includes cabin body 10, hatch 11, fixed hinge 12 and telescopic rod 13. The support column 7 and the square supporting point 9 are arranged in the cabin body 10;The fixed hinge 12 is installed on the upper edge of the cabin body 10, and the hatch 11 is connected with the cabin body 10 by the fixed hinge 12;One end of the telescopic rod 13 is connected with the hatch 11, and the other end is connected with the support column 7. The telescopic rod 13 connects the hatch 11 and the support column 7, which facilitates to provide support when the hatch 11 is opened, prevents the hatch 11 from sagging due to self-weight or affecting the normal work of the device when closed, so as to ensure the stable opening and closing of the hatch 11.
[0041] The telescopic rod 13 includes hydraulic rod 14 and hydraulic cylinder 15, as shown in Figure 5 The other end of the hydraulic rod 14 is also provided with a square mounting structure. The combination design of the hydraulic cylinder 15 and the hydraulic rod 14 can realize smooth telescopic motion, so that the opening and closing process of the hatch 11 is more stable.
[0042] In a preferred embodiment, the battery cabin also includes a slide rail (not shown in the figure), and the spraying mechanism is installed on the slide rail.
[0043] In the embodiment, the battery pack ejecting mechanism and the hydraulic mechanism are installed in the cabin 10. One end of the hydraulic mechanism is connected with the main control mechanism, and the other end is connected with the cylinder 1. The hydraulic mechanism provides power to the cylinder 1 under the control of the main control mechanism, so that the push rod 4 can push the battery pack 6, and then eject the battery pack 6 from the cabin 10.
[0044] In a specific embodiment, the fire detection mechanism is installed in the battery pack 6, which is used to collect fire signals such as temperature and smoke in real time, and send them to the main control mechanism. The main control mechanism is composed of an embedded device, such as a single-chip microcomputer or a microcontroller (MCU), which is installed outside the cabin 10.
[0045] In addition, the PACK-level fire-fighting device also includes a liquid cooling mechanism and a spraying mechanism. The liquid cooling mechanism is installed in the cabin 10, and the liquid cooling mechanism is connected with the main control mechanism, which is used to reduce and stabilize the temperature in the cabin 10. The spraying mechanism is installed on the top of the cabin 10, and the spraying mechanism is provided with a thermal imaging device and a high-pressure spraying device. The thermal imaging device accurately detects the position of the ejected battery pack 6, and the high-pressure spraying device performs fire-fighting on the ejected battery pack 6.
[0046] Preferably, the spraying mechanism is installed in the slide rail on the top of the cabin 10, and the spraying mechanism is adjusted according to the abnormally high temperature area identified by the thermal imaging device, i.e. the position of the ejected battery pack 6, and moves to the position closest to the ejected battery pack 6, so as to ensure that the spraying mechanism can most effectively cover the battery pack 6 that needs to be cooled or extinguished.
[0047] During the operation of the entire device, the fire detection mechanism collects fire signals such as temperature and smoke in real time, and sends them to the main control mechanism. When one or more battery packs 6 have a fault or a fire occurs, the fire detection mechanism detects corresponding data such as temperature and smoke that abnormally rises, and transmits the information to the main control mechanism. The main control mechanism controls the telescopic rod 13 to open the hatch 11, disconnects the high-voltage switch corresponding to the battery pack 6, reports the fire signal to the fire control center, and increases the power of the liquid cooling mechanism to rapidly cool the cabin 10. At the same time, the main control mechanism controls the battery pack ejecting mechanism to eject the abnormal battery pack 6 from the battery cabin through the pulley 5. After the battery pack 6 is ejected, the main control mechanism controls the telescopic rod 13 to close the hatch 11. The spraying mechanism detects the position of the abnormal battery pack 6 through the thermal imaging device, starts the high-pressure spraying device, and accurately performs fire-fighting on the abnormal battery pack 6.
[0048] In summary, the battery pack ejecting mechanism ejects the faulty or abnormal battery pack 6 from the battery compartment quickly through the rapid action of the ejecting cylinder unit, realizes rapid isolation from normal battery units, and effectively prevents potential fire or fault spread.
[0049] Further, the spraying mechanism can determine the specific position of the battery pack 6 outside the battery compartment through the set thermal imaging device, and start the high-pressure spraying device to accurately extinguish the faulty or abnormal battery pack 6. Since the battery pack 6 is extinguished outside the compartment, the damage to other normal battery units and electrical equipment in the compartment can be reduced, the economic loss caused by fire or fault can be reduced, the service life of the entire energy storage system can be prolonged, the maintenance and replacement costs can be reduced, and the economic benefits can be improved.
[0050] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
