[0022] See also Figure 1-4 , a fixed fire extinguishing device with a rotatable sprinkler head, including an external pipe 1, which is connected to the alarm device. When a fire occurs, water will be poured into the device through the external pipe 1, and a connecting water pipe 11 is provided at the lower end of the external pipe 1, and the other end of the connecting water pipe 11 is connected to the sprinkler head 12, so that water is transmitted to the sprinkler head 12 for spraying. When the connecting water pipe 11 is connected to the sprinkler head 12, the inside of the sprinkler head 12 is provided with a rotating mounting structure in the lawn rotary sprinkler head in the prior art, which will not be repeated here;

[0023] A linkage gear 6 is provided in the outer wall of the external tube 1, and the linkage gear 6 is rotatably mounted on the mounting frame 2, and the mounting frame 2 is mounted on a wall or roof to fix the entire device. A motor 4 is provided on one side of the upper end of the mounting frame 2, and a rotating gear 5 is provided at the lower end of the motor 4. When the motor 4 is started, the linkage gear 6 can be rotated together. The motor 4 is connected to the alarm, and when the alarm is started, the motor 4 will be started synchronously.

[0024] At the lower end of the linkage gear 6 are provided two connecting columns 7, the inner wall of the connecting column 7 is installed with a movable rod 8, and the movable rod 8 is also plugged into the extension tube 10, and the extension tube 10 is plugged into the inner wall of the connecting column 7. When in use, a connecting screw 9 is provided at the bottom end of the movable column 8, and the connecting screw 9 is first threadedly connected to the extension tube 10. By pulling the connecting screw 9, the extension tube 10 can be extended at the same time. The movable column 8 moves downward, and after reaching the appropriate position, the connecting screw 9 is rotated to extend in the inner wall of the extension tube 10 through the characteristics of the threaded connection, and when the movable column 8 is rotated, the connecting screw 9 is extended in the inner wall of the extension tube 10. The movable column 8 also rotates in the connecting column 7. When installing the nozzle 12, the rotating connecting screw 9 is threadedly connected to the connecting turntable 14 in the mounting shell 3 to lock the connecting turntable 14 and the nozzle 12. When the mounting shell 3 is pushed, the extension tube 10 will retract into the connecting column 7. At this time, the bottom of the mounting shell 3 and the mounting frame 2 overlap and can be fixed by the bolt 13. When rotating, the linkage gear 6 rotates to drive the two connecting columns 7 to rotate. After the connecting column 7 rotates, it drives the lower end extension tube 10, i.e., the connecting screw 9, to rotate, and the connecting turntable 14 is rotated, thereby rotating the nozzle 12.

[0025] When disassembling, just remove the bolts 13 and pull the mounting shell 3 to gradually remove it for replacement.

[0026] The working principle of the present invention is as follows: as shown in the figure, it includes an external pipe 1, which is connected to the alarm device. When a fire occurs, water will be poured into the device through the external pipe 1, and a connecting water pipe 11 is provided at the lower end of the external pipe 1. The other end of the connecting water pipe 11 is connected to the sprinkler 12, so that water is transmitted to the sprinkler 12 for watering. When the connecting water pipe 11 is connected to the sprinkler 12, the sprinkler 12 is provided with a rotating mounting structure in the sprinkler head of the lawn rotary water spraying in the prior art, which will not be described in detail here.

[0027] A linkage gear 6 is provided in the outer wall of the external tube 1, and the linkage gear 6 is rotatably mounted on the mounting frame 2, and the mounting frame 2 is mounted on a wall or roof to fix the entire device. A motor 4 is provided on one side of the upper end of the mounting frame 2, and a rotating gear 5 is provided at the lower end of the motor 4. When the motor 4 is started, the linkage gear 6 can be rotated together. The motor 4 is connected to the alarm, and when the alarm is started, the motor 4 will be started synchronously.

[0028] At the lower end of the linkage gear 6 are provided two connecting columns 7, the inner wall of the connecting column 7 is installed with a movable rod 8, and the movable rod 8 is also plugged into the extension tube 10, and the extension tube 10 is plugged into the inner wall of the connecting column 7. When in use, a connecting screw 9 is provided at the bottom end of the movable column 8, and the connecting screw 9 is first threadedly connected to the extension tube 10. By pulling the connecting screw 9, the extension tube 10 can be extended at the same time. The movable column 8 moves downward, and after reaching the appropriate position, the connecting screw 9 is rotated to extend in the inner wall of the extension tube 10 through the characteristics of the threaded connection, and when the movable column 8 is rotated, the connecting screw 9 is extended in the inner wall of the extension tube 10. The movable column 8 also rotates in the connecting column 7. When installing the nozzle 12, the rotating connecting screw 9 is threadedly connected to the connecting turntable 14 in the mounting shell 3 to lock the connecting turntable 14 and the nozzle 12. When the mounting shell 3 is pushed, the extension tube 10 will retract into the connecting column 7. At this time, the bottom of the mounting shell 3 and the mounting frame 2 overlap and can be fixed by the bolt 13. When rotating, the linkage gear 6 rotates to drive the two connecting columns 7 to rotate. After the connecting column 7 rotates, it drives the lower end extension tube 10, i.e., the connecting screw 9, to rotate, and the connecting turntable 14 is rotated, thereby rotating the nozzle 12.

[0029] When disassembling, just remove the bolts 13 and pull the mounting shell 3 to gradually remove it for replacement.
