The system is composed of a sprinkler, a sensing alarm valve group and other components, and also includes a pipeline and a water supply facility.

[0003] The patent with publication number CN214808061U discloses an "indoor fire-fighting automatic water spray fire extinguishing system, which relates to the field of indoor fire-fighting automatic water spray fire extinguishing systems and is composed of a mounting plate, a first water pipe, a water blocking disc, a directional water spray head and a smoke sensor. One end of the mounting plate is provided with the first water pipe, which includes a steel pipe. The lower surface of the steel pipe is fixedly connected with an annular protruding portion. The water blocking disc is threadedly connected to the bottom of the mounting plate. The inner wall of the water blocking disc is threadedly connected with the directional water spray head.

[0031] After the multi-stage electric push rod 44 is retracted, the adapter between the ball seat 3 and the ball 31 can adjust the inclination angle of the directional water spraying pipe 32 and the spray head 33. When the motor 4 operates, the rotating disc 42 will rotate, and the rotating disc 42 after rotation will drive the rotating block 43 at the edge to move in the circumferential direction.

[0036] The implementation principle of the automatic water spraying fire extinguishing system in the embodiment is as follows:

[0037] In use, when a fire occurs, smoke will be generated. After the smoke sensor 2 senses the smoke of the fire, it will alarm and automatically open the large-area spraying mechanism 11 and the water spraying mechanism to spray water to prevent the spread of the fire.

After the multi-stage electric push rod 44 extends and retracts, the connection between the ball seat 3 and the ball 31 is matched, and the inclination angle of the directional water spraying pipe 32 and the spray head 33 can be adjusted.

[0039] When the motor 4 operates, the rotating disc 42 is driven to rotate, and the rotating block 43 at the edge is driven to move in the circumferential direction. At this time, the multi-stage electric push rod 44 is matched to extend and retract, and the directional water spraying pipe 32 is driven to rotate in the circumferential direction, so that the direction and position of the spray head 33 can be quickly adjusted. The spray head 33 can be used to spray water on different positions of the fire source, and the large-area spraying mechanism 11 can be used to spray water on a large area, so that the fire source can be extinguished in time to save losses.
