[0003] The core of fire prevention and control is to "prevent a disaster from happening", and to efficiently and quickly extinguish the fire source at the first time when the fire occurs, so as to minimize personnel casualties and property losses. At present, the fire-fighting regulations have clearly stipulated that personnel-intensive buildings must be equipped with fire-fighting and fire extinguishing facilities, especially in personnel-intensive places, an automatic fire extinguishing spraying system needs to be installed.

[0004] In the prior art, the automatic fire extinguishing spraying system generally adopts a passive fire extinguishing water spraying mode, that is, water is automatically sprayed to extinguish the fire after the fire occurs, but this mode has the following problems:

The fire control alarm console is provided with PC and APP data synchronization functions, and can realize remote control. When the fire source is extinguished, the sensor 804 outputs a signal through the central control circuit board to close the electromagnetic valve, stop water output, stop the alarm signal, reset the fire extinguisher, and complete the fire extinguishing work.

[0095] As shown in FIGS. 6-8, the stator 1 is provided with a fixing piece 13, and the top of the fixing piece 13 is provided with a fixing bracket 14. The fixing piece 13 and the fixing bracket 14 can be used to fix the stator on the installation wall.

[0096] In order to remotely know the state of the fire extinguishing equipment, a communication module can also be installed on the fire extinguishing equipment, and the communication module transmits to the control console, so that the PC or APP can synchronously display the data. The communication technology of the communication module is a conventional technology on the market, which is not described in detail here.

[0097] Referring to FIGS. 1-8, the working principle of the present application is described as follows:

[0098] When a fire occurs, the sensor 804 senses the fire, and the sensor 804 sends a fire signal to the central control circuit board. The central control circuit board sends a signal to the control circuit board 6, so that the control circuit board 6 controls the rotor 2 to start rotating. The rotor 2 drives the nozzle 41 to rotate through the support 80. When the nozzle 41 rotates to a specified position, the central control circuit board sends a signal to control the control circuit board 6 to control the adjustment power source 81 to start. The adjustment power source 81 drives the nozzle 41 to rotate through the transmission structure 82, so that the nozzle 41 faces the fire. Then, the central control circuit board sends a signal to control the electromagnetic valve 12 to open. The fire extinguishing medium passes through the water inlet pipe 11, the medium passage 4 and the nozzle 41 in turn, and is finally sprayed from the nozzle 41 to extinguish the fire.

[0099] Embodiment 2

[0100] Referring to FIG. 9, the difference between the present embodiment and the above-mentioned embodiments is that in the present embodiment, the rotor and the mover are provided with a rotation limiting structure 23 for limiting the rotation angle of the rotor. The rotation limiting structure 23 includes a limiting protrusion 231 arranged on the stator and a cooperating protrusion 232 arranged on the rotor 2 corresponding to the limiting protrusion 231.

[0101] In the present embodiment, the limiting protrusion 231 and the cooperating protrusion 232 limit the rotation angle of the rotor 2, so as to ensure that the rotor 2 can only rotate back and forth by 360°, and the rotor 2 will not be excessively rotated.

[0102] Embodiment 3

[0103] Referring to FIG. 10, the difference between the present embodiment and the above-mentioned embodiments is that in the present embodiment, the rotation structure 23 further includes two proximity switches 233. The two proximity switches 233 are installed on the end cover 21 and symmetrically distributed about the connecting line of the center point of the stator 1 and the limiting protrusion 231. In the process of rotation of the rotor 2, the proximity switch 233 will be moved, and the proximity switch 233 will sense the contact and passing of the cooperating protrusion 232.

[0104] The embodiment sends a signal before the cooperating protrusion 232 on the rotor 2 and the limiting protrusion 231 hard contact, and provides a signal for the brake device 5 to brake the rotor 2, reduces the impact force generated by the collision between the limiting protrusion 231 and the cooperating protrusion 232, and prolongs the service life of the stator 1 and the rotor 2.

[0105] Embodiment 4

[0106] Referring to FIGS. 11-15, the difference between the embodiment and the above-mentioned embodiments is that a protective cover 801 is installed on the bracket 80 in the embodiment, the protective cover 801 is provided with a spray hole 802, a plugging piece 803 corresponding to the spray hole 802 is installed on the spray head 41, and the spray head 41 drives the plugging piece 803 to rotate synchronously when the spray head 41 is adjusted up and down.

[0107] The embodiment protects the motor and the spray head 41 by the protective cover 801, prevents external substances from directly impacting the motor or the spray head 41, ensures that the fire extinguishing medium can be sprayed from the spray hole 802 to extinguish the fire, and prevents a large amount of dust from directly contacting the motor to affect the service life of the motor by the setting of the plugging piece 803.

[0108] Referring to FIGS. 11-15, the plugging piece 803 includes a connecting plate 8031 fixedly installed on the spray head 41 by welding or the like, and an arc-shaped baffle 8032 installed on the connecting plate 8031, which corresponds to the spray hole 41.

[0109] The embodiment synchronously drives the arc-shaped baffle 8032 to rotate by fixing the connecting plate 8031 on the spray head 41, and the arc-shaped baffle 8032 is used to plug the spray hole 41 to prevent dust from entering the spray hole 41 and reduce internal dust by the setting of the arc-shaped baffle 8032. It needs to be particularly pointed out that the advancing end of the arc-shaped baffle 8032 is provided with a slope, that is, the end of the arc-shaped baffle 8032 away from the spray head 41 is provided with a slope, which can effectively prevent the arc-shaped baffle 8032 from interfering with the protective cover 801 during rotation. Simply speaking, when the fire extinguishing medium needs to be sprayed to extinguish the fire, the spray head 41 will rotate, which will drive the arc-shaped baffle 8032 to rotate synchronously, and the end of the arc-shaped baffle 8032 away from the spray head 41 is the advancing end at this time.

[0110] Referring to FIGS. 11-15, in the embodiment, the normal projection of the spray head 41 on the second plane and the normal projection of the connecting plate 8031 on the second plane form an opening angle facing the arc-shaped baffle 8032; when the spray head 41 rotates to any angle, the normal projection of the spray head on the second plane does not coincide with the normal projection of the connecting plate on the second plane, so that when the spray head 41 sprays the fire extinguishing medium, the fire extinguishing medium will not hit the arc-shaped baffle 8032, and the fire extinguishing medium can be sprayed onto the fire source to extinguish the fire.

[0111] The above embodiments are illustrative of the present application, not limiting the present application, and any simple transformation of the present application also belongs to the protection scope of the present application.
