Description

Fire spread prevention device {FIRE SPREAD PREVENTION DEVICE}

The present invention relates to a fire spread prevention device, and more specifically, to a fire spread prevention device that detects a fire in an ESS electrical room, prevents the spread of fire, and extinguishes the fire.

In the case of existing ESS (Energy Storage System) electrical rooms, when a fire breaks out during the day or night, most of the electrical rooms are completely burned down. In particular, the ESS electrical rooms have densely placed battery racks, so when a fire breaks out, the fire spreads to surrounding battery racks and burns down. It's a situation.

Until recently, there were no legal regulations on the internal structure of the ESS electrical room, so it was inevitable to place as many battery racks as possible in the space provided inside the electrical room, which inevitably increased the damage caused by fire.

Considering these problems, regulations have recently been created to regulate the spacing of battery racks in ESS electrical rooms, and battery racks are installed at a certain distance apart.

However, even if the ESS electrical room forms a safe distance between battery racks, if a fire occurs, the problem remains that it cannot prevent the fire from spreading to the surrounding area and increasing damage because the battery cells generate high temperatures and heat.

Through this, the upper surface of the horizontal moving part 159 can fix the corrugated pipe member 14 by contacting one side of the lower surface of the corrugated pipe lowering weight 141 of the corrugated pipe member 14 based on a control signal in normal times. On the other hand, in the event of a fire, the horizontal moving part 159 moves horizontally in the direction of the driving motor 155 along the screw 157 when the driving motor 155 is operated based on the control signal to release the fixation of the corrugated pipe member 14. I do it.

Meanwhile, the solenoid valve 161 is connected to the drive motor 155 by wire and is provided to supply power to the drive motor 155, and is installed on the upper surface of the first holder 151 or on one inner side of the exhaust duct main body 13.

The transmitting and receiving unit 1631 is for transmitting and receiving various information with the comprehensive control device 5 under the control of the control unit 1633. It has low power consumption and complies with the IEEE 80215 standard to be suitable for short-distance wireless communication in the automation field at home or industrial sites. It is a wireless personal area network standard based on , and can have a relatively low transmission speed of 20 to 250 kbps.

The control unit 1633 may generate and output a driving signal for controlling the operation of the solenoid valve 161 according to the control signal received through the transmitting and receiving unit 1631. And the control unit 1633 compares the device-specific identification information of each solenoid valve 161 included in the received control signal with the identification information of the corresponding solenoid valve 161 and sends a solenoid on-off driving signal to the solenoid current controller 1635. Can be printed.

And when the control unit 1633 receives a control signal that is the on-driving signal of the solenoid valve 161, it operates the drive motor 155 electrically connected to the solenoid valve 161. In this case, the horizontal moving part 159 is driven. As the motor 155 moves horizontally in the direction of the drive motor 155, the corrugated pipe member 14 is unfastened, and the corrugated pipe member 14 is lowered by the weight of the corrugated pipe lowering weight 141, thereby lowering the case (C). ) can be covered.

After the case (C) is covered, the control unit 1633 applies power to the opening and closing valves (21-1, 21-2) to open them, thereby allowing the fire extinguishing agent to flow through the plurality of spray nozzles (22-1, 22-2). The fire can be extinguished by being sprayed through the spray.

And the control unit 1633 uses the power unit 1637 to send a blowing fan driving control signal to the first blowing fan (25) after a certain period of time is delayed after the fire extinguishing agent is sprayed through the plurality of spray nozzles (22-1, 22-2). ) and the second blowing fan 26 to drive the first blowing fan 25 and the second blowing fan 26. Additionally, the control unit 1633 may generate a damper drive signal for the damper 24 and transmit it to a motor connected to the damper 24 to control the damper 24 to be opened by the operation of the motor. At this time, the damper 24 of the other flow pipe 12 is maintained in a closed state rather than opened, thereby preventing contaminated air from flowing into the other flow pipe 12. To this end, the control unit 1633 may be provided to be electrically connected to the first blowing fan 25, the second blowing fan 26, and the damper 24.

The solenoid current controller 1635 can control the current supplied to the solenoid from the power source of the power supply unit 1637.
