Figure 4 is a perspective view for explaining a fire control device according to embodiments of the present disclosure. Hereinafter, for convenience of explanation, description of matters substantially the same as those described with reference to FIGS. 1A, 1B, and 1C will be omitted, and differences will be described in detail.

Referring to FIG. 4, the fire control device according to embodiments of the present disclosure includes a spray device (i.e., a spray device) that sprays fire extinguishing material (i.e., fire extinguishing agent) into the space formed by the fire cover 100 when a fire associated with the target device is detected. 400) may further be included. At this time, extinguishing substances include, for example, carbon dioxide (CO ₂ ), aluminum sulfate (Al ₂ (SO ₄ ) ₃ ), ammonium phosphate ((NH ₄ ) ₄ PO ₄ ), Halon 1211, Halon 1301, Halon 2402, and water. It may include at least one of (H ₂ O).

The spray device 400 may include pipes that move and spray extinguishing substances. According to embodiments, the injection device 400 includes a first injection pipe 410 for spraying fire extinguishing material to the upper surface of the target device, a second spray pipe 420 for spraying fire extinguishing material to the side of the target device, and a first spray It may include a first valve 430 that controls the pipe 410 and the second injection pipe 420. At this time, the first injection pipe 410 and the second injection pipe 420 may be arranged in various ways so that the extinguishing material is sprayed to the top or side of the target device, and their positions and shapes are not limited to those shown.

According to other embodiments, the first injection pipe 410 may spray fire extinguishing material from above the target device, and the second spray pipe 420 may spray fire extinguishing material from the side of the target device. At this time, the first injection pipe 410 and the second injection pipe 420 may be disposed above or on the side of the target device, and the direction in which the extinguishing material is sprayed is not limited to that shown.

According to an example shown in FIG. 4, the first injection pipe 410 may extend along the second direction (y). At this time, the second injection pipe 420 is connected to the first injection pipe 410 and extends along the first direction (x), and then bends adjacent to the frame 300 and extends along the third direction (z). It can be. According to embodiments, a plurality of second injection pipes 420 may be provided, and each of the plurality of second injection pipes 420 may be disposed adjacent to the first portion 310 of the frame 300. .

Each of the first injection pipe 410 and the second injection pipe 420 may have at least one opening through which the extinguishing material is sprayed. For example, the opening of the first injection pipe 410 may face the upper surface of the rack (R), and the opening of the second injection pipe 420 may face the side of the rack (R). For example, the diameter of the opening of the first injection pipe 410 may be larger than the diameter of the opening of the second injection pipe 420. Additionally, for example, the shape of the opening of the first injection pipe 410 may be different from the shape of the opening of the second injection pipe 420. According to embodiments, the openings of each of the first injection pipe 410 and the second injection pipe 420 may protrude from each of the first injection pipe 410 and the second injection pipe 420. Meanwhile, by forming the first and

second injection pipes

410 and 420 in this way, the fire extinguishing material can be sprayed into each part of the target device, and a large amount of fire extinguishing material can be sprayed simultaneously so that the target device can be sprayed on the fire extinguishing material in a short period of time. It can be locked in time. On the other hand, when the target device includes a battery cell of an energy storage device, a large amount of fire extinguishing material sprayed through the first injection pipe 410 can lower the temperature of the target device and is discharged through the second injection pipe 420. The sprayed extinguishing material can directly contact the battery cell, helping to directly extinguish the fire in the battery cell.

The first valve 430 may control at least one of whether to inject fire extinguishing material through each of the first injection pipe 410 and the second injection pipe 420, the injection amount, and the injection speed. The first valve 430 may be, for example, a solenoid valve that opens and closes by a current signal.

According to embodiments, as the spray device 400 sprays the fire extinguishing material, the fire extinguishing material may fill the space formed by the fire cover 100. At this time, at least some of the target devices may be submerged in the filled fire extinguishing material. That is, the fire cover 100 may form a water tank filled with extinguishing substances, and at least some of the target devices may be submerged in the water tank.

According to the fire control device and its control method according to embodiments of the present disclosure, the oxygen supply is blocked by deploying the fire cover 100 to prevent the oxygen concentration in the area adjacent to the target device from reaching the oxygen concentration required for combustion. In addition to using a suffocation fire extinguishing method, a cooling fire extinguishing method is used to prevent the temperature of the target device from reaching the flash point (i.e., ignition point) by using state change energy by spraying fire extinguishing material into the space formed by the fire cover 100. By using it, you can prevent the spread of fire and minimize damage from fire.

That is, when the raising of the fire cover 100 is completed (that is, when the deployment of the fire cover 100 is completed), the fire cover sensor can control the spray device 400 to spray the fire extinguishing material.

More specifically, when the fire cover 100 is raised above a certain height, at least one of direct input and indirect input may be transmitted to the fire cover sensor, and accordingly, the fire cover sensor may send a signal for controlling the injection device 400. can be created. A case where a direct input is transmitted to the fire cover sensor may be, for example, a case where the fire cover 100 directly contacts the fire cover sensor. Additionally, when an indirect input is transmitted to the fire cover sensor, for example, at least one of an electrical signal and a mechanical signal regarding the rising height of the fire cover 100 may be transmitted to the fire cover sensor. However, this is only an example and the present disclosure is not limited thereto, and even if the rise of the fire cover 100 is not completed (i.e., even if the fire cover 100 is not fully deployed), a spray device ( Extinguishing material may be sprayed from 400). The fire cover sensor may be placed on at least one of the rack (R) where the target device is placed, the target device, the fire cover 100, the deployment device 200, and the frame 300.

Meanwhile, according to embodiments, the fire cover sensor may perform an operation for fire control after the fire cover 100 is deployed when the space formed by the fire cover 100 satisfies set conditions. For example, if a part of the target device that requires fire control is located in the space formed by the deployed fire cover 100, the fire cover sensor can control the spray device 400 to spray the fire extinguishing material, and The fire in the target device can be controlled by the extinguishing agent filling the space. In this way, the fire cover sensor can check the part requiring fire control, and in response, check whether the fire cover 100 has been deployed to the extent that fire control can be performed, and the spray device 400 can detect the fire extinguishing agent. can be effectively controlled to spray.

Additionally, according to embodiments, the fire cover sensor may check whether the fire cover 100 is deployed by detecting the operating state of the deployment device 200. For example, when the deployment device 200 includes a fluid cylinder 210, the fire cover sensor detects whether the fluid cylinder 210 has operated to the extent necessary for deployment of the fire cover 100 and detects whether the fire cover 100 is operated to the extent necessary to deploy the fire cover 100.

That is, when the extinguishing agent reaches the level corresponding to the level sensor 500, the level sensor 500 can control the spraying device 400 to stop spraying the extinguishing agent. Additionally, the discharge device 600 may be controlled to discharge the extinguishing material according to the detection signal of the level sensor 500.
