As shown in fig. 1 to fig. 9, the working principle of the intelligent fire-proof sealing control system based on the internet of things provided by this embodiment is as follows:
the intelligent fire-proof sealing control system based on the internet of things is a quick response device taking water as power, when a fire disaster is detected by the fire detection equipment 20, the valve of the electromagnetic valve 414 is opened by the control equipment 30, the water can drive the fire-proof roller shutter 411 to fall down, when the fire-proof roller shutter 411 falls to the bottom, the mesh plate 4111 sprays water, and when spraying water, the energy storage mechanism 42 stores energy, and after the valve of the electromagnetic valve 414 is closed, the fire-proof roller shutter 411 automatically rises. The design aims to drive the device to operate only by the kinetic energy of water when no power supply is available in an unexpected situation.
When the valve of the solenoid valve 414 is opened, water flows through the valve into the left piston chamber 434. Water simultaneously flows through the spiral reel 432 into another piston chamber 434. Both pistons 416 travel downward simultaneously. Causing the wire drum 417 to rotate. While the fire curtain 411 descends. When the piston 416 descends to the bottom, the fire curtain 411 descends to the bottom at the same time. The piston 416 pushes down the lift valve plate 433, and when the piston 416 is lowered to the bottom, the piston 416 stops moving, and water flows through the piston core 4162 of the piston 416 through the lift valve plate 433 into the interior of the nozzle 431.
Since the fire curtain 411 has been lowered to the bottom and engages the bottom nozzle 431, water flows through the nozzle 431 into the interior of the fire curtain 411 and is sprayed out through the mesh plate 4111. The purposes of isolating the fire source and extinguishing fire are achieved.
