Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a fire sprinkler device, including a first water pipe 1, a second water pipe 2, a third water pipe 3, and a nozzle 4. The outer sides of both the first water pipe 1 and the second water pipe 2 are provided with toothed grooves 18. The large end of the nozzle 4 is fixedly connected to the output end of the first water pipe 1. A first motor 5 and a second motor 6 are fixedly mounted on the outer sides of both the second water pipe 2 and the third water pipe 3. Worms 7 are rotatably connected to the interiors of both the second water pipe 2 and the third water pipe 3. The outer side of the worm 7 meshes with the inner side of the toothed grooves 18. An angle sensor 8 is fixedly mounted on the outer side of the worm 7. A first transmission disc 9 and a second transmission disc 10 are coaxially fixed to both ends of the worm 7. A third transmission disc 11 is slidably connected to the outer side of the output shaft of the first motor 5, and the third transmission disc 11 meshes with the first transmission disc 9. A fourth transmission disc 12 is slidably connected to the outer side of the output shaft of the second motor 6, and the fourth transmission disc 12 meshes with the second transmission disc 10. In the transmission, a spring 13 abuts against the side of the fourth transmission disc 12 away from the worm 7. Two connecting plates 14 are fixed on the outer circumference of the fourth transmission disc 12. Two connecting lines 15 are fixed between the two connecting plates 14 and the second motor 6. Two blades 16 are fixed on the outer side of the second motor 6. A connecting rod 17 is slidably connected inside the worm 7. The two ends of the connecting rod 17 are rotatably connected to the outer sides of the third transmission disc 11 and the fourth transmission disc 12, respectively. The first water pipe 1 is rotatably connected to the second water pipe 2, and the second water pipe 2 is rotatably connected to the third water pipe 3. The axis of the worm 7 is on the same axis as the axis of the first motor 5 and the second motor 6. The worm 7 is located between the first motor 5 and the second motor 6. The positions of the two blades 16 correspond to the positions of the two connecting lines 15, respectively. The axis of the connecting rod 17 is on the same axis as the axis of the third transmission disc 11 and the fourth transmission disc 12. One end of the spring 13 abuts against the outer side of the second motor 6.

[0023] The first motor 5 meshes with the first transmission disc 9 on the worm gear 7 via the third transmission disc 11, thereby driving the worm gear 7 to rotate. The worm gear 7 rotates via the toothed grooves 18 on the first water pipe 1 and the second water pipe 2. Since the rotation directions of the first water pipe 1 and the second water pipe 2 are horizontal and vertical respectively, the horizontal and vertical angles of the nozzle 4 are controlled. When the first motor 5 malfunctions due to prolonged inactivity, the angle sensor 8 on the worm gear 7 does not detect rotation within a specified time. At this time, the second motor 6 is started, and the second motor 6 drives the fourth transmission disc 12 to rotate. The connecting wire 15 on the upper part comes into contact with the blade 16 and breaks. Then, under the push of the spring 13, the fourth transmission disc 12 and the second transmission disc 10 mesh with each other. At the same time, the fourth transmission disc 12 pushes the third transmission disc 11 and the first transmission disc 9 to separate from each other through the connecting rod 17, so as to prevent the second transmission disc 10 from jamming when the first motor 5 jams. Through the above process, when one motor fails, the other motor can be replaced in time, improving the fault tolerance of the device and solving the problem that idle motors may fail when not used for a long time, thus affecting the normal operation of the fire monitor.

[0024] The specific usage and function of this embodiment: In this utility model, the first motor 5 meshes with the first transmission disk 9 on the worm gear 7 through the third transmission disk 11, thereby driving the worm gear 7 to rotate. The worm gear 7 drives the first water pipe 1 and the second water pipe 2 to rotate through the toothed grooves 18 on the first water pipe 1 and the second water pipe 2. Since the rotation directions of the first water pipe 1 and the second water pipe 2 are horizontal and vertical respectively, the horizontal and vertical angles of the nozzle 4 are controlled. When the first motor 5 is idle for a long time and malfunctions, the angle sensor 8 on the worm gear 7 does not detect rotation within a specified time. At this time, The second motor 6 is started, which drives the fourth transmission disk 12 to rotate. The connecting wire 15 on the fourth transmission disk 12 comes into contact with the blade 16 and breaks. Then, under the push of the spring 13, the fourth transmission disk 12 and the second transmission disk 10 mesh with each other. At the same time, the fourth transmission disk 12 pushes the third transmission disk 11 and the first transmission disk 9 to separate from each other through the connecting rod 17, so as to prevent the second transmission disk 10 from jamming when the first motor 5 jams. Through the above process, the other motor can be replaced in time when one motor fails, improving the fault tolerance of the device.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
