[0045] Example 2
[0046] Based on the first embodiment, and different from the first embodiment,
[0047] A building fire automatic alarm sprinkler device, further comprising:
[0048] The rotating assembly 600 is used to drive the mounting plate 200 to rotate.
[0049] The rotating assembly 600 includes a forward and reverse motor 601 fixed on the upper surface of the sliding plate 501, and a driving gear 602 is fixed at the output end of the forward and reverse motor 601, and a driven gear 603 is fixed on the outer surface of the rotating tube 401 and meshed with the driving gear 602. The rotation of the mounting plate 200 can be achieved by the forward and reverse rotation of the forward and reverse motor 601.
[0050] The forward and reverse motor 601 is electrically connected to the PLC controller 407 via wires.
[0051] In this embodiment, by providing the rotating assembly 600, the purpose of rotary spraying fire extinguishing can be achieved when a fire occurs, and the uniformity and range of the spraying are effectively improved, which is highly practical.
[0052] When the device is in operation, when it is installed, a mounting groove can be first opened on the ceiling of the building corridor, and the mounting box 100 can be installed in the mounting groove so that the lower surface of the mounting box 100 is flush with the top wall of the ceiling. When a fire occurs, the smoke sensor 408 transmits a signal to the PLC controller 407, and the PLC controller 407 automatically controls the alarm 4014, the drive motor 502, the water pump 402 and the small dual-axis motor 4011 to start. The rotation of the drive motor 502 drives the threaded column 503 to rotate, and the rotation of the threaded column 503 drives the sliding plate 501 to move downward, thereby driving the mounting plate 200 to move downward and out of the rectangular opening 300. At the same time, the small dual-axis motor 4011 rotates, driving the two lead screws 4012 to rotate, and the rotation of the two lead screws 4012 drives the two sliders 4013 to move to both sides at the same time, thereby driving the two L-shaped tubes 405 and the atomizing nozzle 406 to move out of the sliding cavity 404, and the water pump 402 will pump the water in the tap pipe. The water is transported to the rotating tube 401 through the water delivery hose 409, and after entering the channel 403, it is transported to the L-shaped tube 405 through the connecting hose 4010 and sprayed out through the atomizing nozzle 406 to achieve automatic fire extinguishing. At the same time, an alarm is sounded through the alarm 4014, so that the device can be installed inside the ceiling to avoid damage to the device due to collision with objects, ensuring that it can normally extinguish fire in case of fire. Moreover, when extinguishing a fire, the atomizing nozzle 406 can be automatically moved out of the installation box 100 for fire extinguishing, which is highly practical. In addition, when a fire occurs, the PLC controller 407 automatically controls the rotation of the forward and reverse motor 601. The rotation of the forward and reverse motor 601 drives the active gear disc 602 to rotate. The rotation of the active gear disc 602 drives the driven gear disc 603 and the rotating tube 401 to rotate, thereby driving the mounting plate 200 to rotate forward and reverse, thereby achieving the purpose of rotary spray fire extinguishing, effectively improving the uniformity and range of spraying, and being highly practical.
