Description

Technical Field

[0001] The utility model relates to the field of intelligent fire sprinkler devices for high-rise buildings, and specifically refers to an intelligent fire sprinkler device for high-rise buildings. Background Art

[0002] The fire sprinkler system is a fire extinguishing device and a widely used fixed fire fighting facility. It is generally installed under the indoor ceiling and consists of a sprinkler pipe network and multiple sprinkler heads connected thereto. Since the sprinkler system is always filled with a large amount of water, and due to weather changes and temperature drops, the water in the sprinkler pipes and sprinkler heads is also very likely to freeze, resulting in the sprinkler system being blocked by ice when water spraying is needed to extinguish the fire. The sprinkler head cannot spray water and the sprinkler cannot be effectively used for fire extinguishing. In addition, the general sprinkler head is set vertically downward. When a fire occurs, the heat is transferred to the thermistor through the thermosensitive solution in the thermosensitive glass tube blocked at the nozzle. The volume of the thermosensitive solution expands and shatters the glass tube, so that the blocked water flow is ejected from the nozzle. On the one hand, the sprayed water almost never covers downward, or is blocked from below by a baffle and splashes around. No matter which method is used, there is always a possibility of dead corners for the spray water to cover. On the other hand, the glass slag that falls after the explosion of the glass tube can easily injure people. Therefore, a smart fire sprinkler device for high-rise buildings is needed.

It is used to monitor the amount of water in the water tank 13. A heating chamber 19 is connected to the bottom of the water tank 13 to keep the water in the water tank 13 at a constant temperature. A plurality of support frames 20 are connected to the heating chamber 19 to wind an electric heating element 21. The support frames 20 are connected to the electric heating element 21 to provide heat for the heating chamber 19 and the water tank 13. A power supply device 22 that cooperates with the heating element is downwardly connected to one side of the bottom end of the water tank 13 to provide power for the operation of the heating element. A partition 15 is connected to the top of the heating chamber 19 of the water tank 13 to isolate the water in the water tank 13 from the electric heating element 21 below.

[0019] A thermal sensor 12 is downwardly connected to one side of the bottom end of the water tank 13 for sensing the indoor temperature. A water pipe 2 is connected to the bottom end of the water tank 13 for transporting the water in the water tank 13 to the nozzle 4. A water pump 11 matching the thermal sensor 12 is connected to the water pipe 2 for pumping the water in the water tank 13 out and sending it to the nozzle 4 for spraying. Nozzles 4 are connected to both sides of the bottom end of the water pipe 2. The nozzles 4 are the nozzles 4 provided on the spray device. A No. 2 tee pipe 17 is connected between the water pipe 2 and the nozzles 4. The No. 2 tee pipe 17 is a 45-degree inclined tee pipe setting, so that the nozzles 4 connected on both sides are tilted downward. The nozzles 4 cooperate with each other to connect the water pipe 2 and the nozzles 4 on both sides. The nozzles 4 are rotatably connected with a transmission shaft 7 for Drive the fan plate 8 to rotate, the nozzle 4 is connected with a motor 23 matched with the transmission shaft 7 to provide power for the rotation of the transmission shaft 7, the nozzle 4 is connected with a motor box 5 and a motor frame 10 matched with the motor 23, which are used to support and protect the motor 23 placed in the nozzle 4 filled with water, the transmission shaft 7 is respectively connected with a sealing bearing 6 between the motor box 5 and the nozzle 4, which is used for sealing to prevent water leakage at the connection, thereby affecting the operation of the motor 23, the transmission shaft 7 extends to the bottom end of the nozzle 4 and is connected with a connecting block 18, the connecting block 18 is connected with a plurality of fan plates 8 matched with the nozzle 4, when rotating below the water outlet of the nozzle 4, it is used to disperse the water sprayed from the nozzle 4, the fan plate 8 is connected with a plurality of through holes 9, so that part of the water falls through the through holes 9.
