[0002] Energy storage containers are a type of electric energy storage equipment that consists of multiple battery modules, and the number of battery modules can be set according to specific needs. Considering land costs and other reasons, the distance between adjacent energy storage containers is relatively close. Once a battery module catches fire or explodes, it will be difficult to extinguish it immediately, and it is likely to have an adverse effect on adjacent energy storage containers, and even cause thermal runaway fire.

The cabinet is equipped with a battery module and is located above the fire water tank. The cabinet is connected to the lifting end of the lifting mechanism. When the battery module in the cabinet thermally runs away and catches fire, the cabinet can be driven by the lifting mechanism to descend into the fire water tank, so that the battery module can be cooled by the water in the fire water tank, so that the fire can be extinguished in time at the early stage of the fire, and the fire can be prevented from spreading to adjacent energy storage cabinets.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0031] Combine the following Figures 1 to 3 The fire extinguishing device provided by the utility model is introduced with reference to specific embodiments. The fire extinguishing device can isolate the energy storage container 100 that is on fire and deflagration to avoid affecting the adjacent energy storage containers 100.

[0032] Specifically, the fire extinguishing device is contained in a receiving groove, which is provided at the bottom of the inspection passage between adjacent energy storage containers 100. In this embodiment, the energy storage container 100 is placed on a horizontal plane, and the receiving groove is provided on the horizontal plane. Figure 1 As shown, the fire extinguishing device includes a lifting mechanism 1 and a fire baffle 2, wherein the lifting mechanism 1 is fixedly arranged in the receiving groove, and the fire baffle 2 includes an insulation layer 21, and the insulation layer 21 is connected to the lifting end of the lifting mechanism 1 so that the insulation layer 21 can be movably passed through the opening of the receiving groove in the vertical direction.

[0033] Through the fire extinguishing device, when the energy storage container 100 is in normal operation, the fire baffle 2 is in a retracted state and buried under the horizontal plane, and does not occupy the maintenance passage between the energy storage containers 100, thereby ensuring the maintenance efficiency and quality; when the energy storage container 100 catches fire, the lifting mechanism 1 can control the fire baffle 2 to rise, and isolate the energy storage container 100 that is on fire and deflagration from the normal energy storage container 100, and the heat insulation layer 21 can prevent the heat generated by thermal runaway from spreading to the adjacent energy storage container 100, thereby avoiding the risk of thermal runaway of the adjacent energy storage container 100.

[0034] Furthermore, inspection passages are arranged around the energy storage container 100, and a receiving groove is provided at the bottom of each inspection passage, and a fire-fighting device is arranged in each receiving groove, so that when the energy storage container 100 catches fire, the fire baffles 2 in the fire-fighting devices around it rise out of the ground to surround the burning and deflagrated energy storage container 100, to prevent the fire from being further intensified due to the wind force at the scene, and to ensure that the fire can be quickly extinguished under the condition of enclosure.

[0035] In this embodiment, the energy storage container 100 is further provided with a sensor 110 and a controller 120. The sensor 110 may be a smoke sensor 110, a flame sensor, a temperature sensor or a humidity sensor, etc., and the utility model is not limited thereto. The controller 120 is electrically connected to the sensor 110 and the lifting mechanism 1 located around the energy storage container 100. Through the above arrangement, when the sensor 110 detects a fire signal, the sensor 110 automatically sends a detection signal to the controller 120, so that the controller 120 can timely control the lifting mechanisms 1 around to simultaneously rise out of the ground, and enclose the energy storage container 100, thereby improving the immediacy of the fire extinguishing device, ensuring that the fire baffle 2 can timely and effectively block the fire, and further avoiding the spread of the fire.

[0036] Specifically, refer to Figure 2 As shown, the lifting mechanism 1 includes a lifting motor 11 and a lifting rod 12. The lifting motor 11 is arranged in the receiving groove. The fixed end of the lifting motor 11 is connected to the controller 120, and its output end is connected to the lifting rod 12 in a transmission manner. The outer surface of the lifting rod 12 is provided with an external thread structure, and the interior of the fire damper 2 has an internal thread hole, and the external thread structure is threadedly connected in the internal thread hole. When the sensor 110 detects a fire signal, the controller 120 can control the lifting motor 11 to start, and the output end of the lifting motor 11 can drive the lifting rod 12 to rotate around its own axis, thereby driving the fire damper 2 to rise and fall along the axis of the lifting rod 12, so that the fire extinguishing device can automatically respond to the fire without manual intervention, thereby improving the efficiency of emergency fire handling, and according to the size of the fire, the lifting height of the fire damper 2 can be adjusted by the lifting rod 12, so as to flexibly respond to the fire extinguishing needs under different circumstances.

[0037] It should be noted that, in this embodiment, each fire damper 2 can be lifted and lowered by a plurality of lifting mechanisms 1 to ensure the stability of the fire damper 2 when it is lifted and lowered. For example, a lifting mechanism 1 is provided at each end of each fire damper 2.

[0038] Optionally, continue to refer to Figure 2 As shown, the lifting mechanism 1 provided in this embodiment further includes a guide seat 13 and a guide rod 14. The guide seat 13 is fixedly arranged in the receiving groove, a guide channel is vertically provided in the guide seat 13, the end of the guide rod 14 is fixedly connected to the fire damper 2, and the guide rod 14 is slidably arranged in the guide channel. By providing the guide seat 13 and the guide rod 14, the stability of the fire damper 2 during the lifting movement can be increased, and the lateral deflection can be prevented, thereby ensuring the isolation and blocking effect on the fire.

[0039] Furthermore, in this embodiment, each fire damper 2 is provided with a plurality of guide seats 13 and a plurality of guide rods 14 to further enhance the lifting stability of the fire damper 2. For example, a guide seat 13 and a guide rod 14 are provided at each end of each fire damper 2.

[0040] Optionally, the fire extinguishing device provided in this embodiment further includes a locking assembly, which is arranged on a horizontal plane and can lock and limit the fire damper 2 to prevent the fire damper 2 from falling when the fire is not completely extinguished.

[0041] Specifically, in this embodiment, a lock hole is provided on the outer side of the fire damper 2; the locking assembly includes a lock seat, a lock block, a stopper, a pull ring and a spring. The lock seat is fixedly arranged on a horizontal plane, a lock path is provided in the lock seat in a horizontal direction, the lock path is relatively arranged to the lock hole, and a through hole is provided at one end of the lock seat away from the lock hole, the through hole is connected to the lock path, the lock block is slidably arranged in the lock path, the stopper and the spring are both located in the lock path, one side of the stopper is fixedly connected to the lock block through the spring, the other side of the stopper is fixedly connected to the pull ring through the through hole, and the spring is configured to be in a compressed state.

[0042] Through the above arrangement, when the lock block is not inserted into the lock hole, the lock is fastened and connected to the fire damper 2. When the fire damper 2 rises to a preset height, the lock hole can be arranged relative to the lock block. At this time, the lock block is inserted into the lock hole under the thrust of the spring, thereby realizing the locking and limiting function of the fire damper 2. In addition, the above locking assembly requires the operator to manually pull the pull ring to remove the lock block from the lock hole, thereby releasing the restriction on the fire damper 2. In this way, compared with relying on electricity or other control systems to achieve automatic locking or automatic unlocking, the failure of the locking or unlocking function caused by power failure can be avoided, thereby ensuring the reliability of the use of the locking assembly.

[0043] Specifically, refer to Figure 3 As shown, the fire baffle 2 provided in this embodiment also includes a cooling layer 22 attached to the heat insulation layer 21, and the cooling layer 22 is provided on at least one side of the heat insulation layer 21. The cooling layer 22 can cool the heat insulation layer 21 to prevent the heat insulation layer 21 from overheating, thereby further improving the safety of the adjacent energy storage container 100. Preferably, a cooling layer 22 is provided on both opposite sides of the heat insulation layer 21 to achieve the maximum cooling effect on the heat insulation layer 21.

[0044] More specifically, in this embodiment, the cooling layer 22 includes a cooling plate 221, a liquid infusion tube 222 and a valve. The cooling plate 221 is fitted on the heat insulation layer 21, and the cooling plate 221 has a water absorption hole and is made of non-flammable material. For example, the cooling plate 221 can be a rock wool board or a glass fiber board. The two ends of the liquid infusion tube 222 are respectively connected to the water absorption hole and the liquid storage tank. The valve is arranged on the liquid infusion tube 222. In this embodiment, the valve is electrically connected to the controller 120 so that the controller 120 can automatically control the closing of the valve. After the fire baffle 2 rises, the valve can be opened immediately, so that the coolant (such as cooling water) in the liquid storage tank can be transmitted to the cooling plate 221 along the liquid infusion tube 222, and the cooling plate 221 is maintained in a saturated state, thereby achieving a cooling effect. At the same time, the fire baffle 2 can reduce the temperature of the adjacent energy storage container 100 without directly spraying water on the adjacent energy storage container 100, avoiding the risk of insulation abnormality caused by direct water spraying.

[0045] In this embodiment, the cooling layer 22 is arranged closer to the energy storage container 100 than the insulation layer 21, which not only makes the fire extinguishing effect more obvious, but also protects the entire fire damper 2 to keep it in a safe state, which helps to extend the service life of the entire fire damper 2.

[0046] Preferably, the thermal insulation layer 21 is made of thermal insulation ceramic board. The thermal insulation ceramic material has excellent thermal insulation performance and high temperature resistance, and is relatively lightweight as a whole, and can meet the thermal insulation requirements under most fire conditions.

[0047] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
