[0032] First embodiment
[0033] Please refer to Figure 1 The embodiment provides an intelligent fire detection spray head 100, which comprises a rotating spray head 10 and a fire detection piece 20. The rotating spray head 10 is provided with a spraying cavity 15. The two ends of the spraying cavity 15 are respectively communicated with a water inlet 112 and a spraying port 122. The water inlet 112 is used for inputting fire-fighting water into the spraying cavity 15. The spraying port 122 is used for spraying fire-fighting water to extinguish fire. Specifically, the rotating spray head 10 can rotate while spraying water, and the spraying range 50 of the fire-fighting water is expanded by the centrifugal action of the water flow.
[0034] Please refer to Figure 1 and Figure 2The fire detection member 20 is arranged at one end of the rotary nozzle 10 where the spray opening 122 is arranged. The fire detection member 20 is used to detect the fire at the side of the rotary nozzle 10. Specifically, in the embodiment, the rotary nozzle 10 is arranged downwardly, and the fire detection member 20 can detect the fire below the rotary nozzle 10. The detection range 40 of the fire detection member 20 is consistent with the spray range 50 of the spray opening 122. It can be understood that the fire detection member 20 is consistent with the orientation of the spray opening 122. In actual use, a plurality of intelligent fire detection nozzles 100 are arranged at intervals on the top of the indoor space, so that the spray range 50 and the detection range 40 of the plurality of intelligent fire detection nozzles 100 can completely cover the planar area of the indoor space. When a fire occurs at a certain place in the indoor space, the fire detection member 20 above the place detects the fire, and the rotary nozzle 10 at the place is started to spray and extinguish the fire below. When the fire is extinguished, the fire detection member 20 detects that the fire is extinguished, and the rotary nozzle 10 is turned off to stop the spraying and extinguishing of the fire. The intelligent fire detection nozzle 100 of the embodiment integrates the fire detection member 20 in the rotary nozzle 10, so that the fire detection member 20 and the rotary nozzle 10 are one-to-one corresponding, the fire can be detected in time and the nozzle can be started to extinguish the fire, and the most appropriate nozzle in the range can be started to extinguish the fire accurately after the fire occurs.
[0035] Please refer to Figure 1 Specifically, the rotary nozzle 10 includes a mounting pipe 11 and a nozzle body 12. The mounting pipe 11 and the nozzle body 12 are connected through a bearing 13. The water inlet 112 is arranged at one end of the mounting pipe 11 away from the nozzle body 12. The spray opening 122 is arranged at one end of the nozzle body 12 away from the mounting pipe 11. It can be understood that the mounting pipe 11 is used to be connected with the water supply pipeline. The nozzle body 12 is movably connected with the mounting pipe 11 and can rotate relative to the mounting pipe 11.
[0036] One side of the bearing 13 is clamped with the side wall of the mounting pipe 11. A clamping groove is formed in the side wall of the mounting pipe 11. The bearing 13 is arranged in the clamping groove, so that the position of the bearing 13 and the mounting pipe 11 is fixed. The other side of the bearing 13 is fixedly connected with the nozzle body 12 through a locking member. In the embodiment, the bearing 13 is arranged as a steel ball. The fastener 14 is arranged as a screw. Specifically, a plurality of steel balls are placed in the clamping groove, and the steel balls can roll in the clamping groove. The steel balls are fixed relative to the nozzle body 12 by the screw. The nozzle body 12 and the steel balls rotate around the mounting pipe 11.
[0037] Further, the installation pipe 11 is provided with a water inlet cavity 111. The nozzle body 12 is provided with a spray cavity 121 which is in communication with the water inlet cavity 111. It can be understood that the water inlet cavity 111 and the spray cavity 121 jointly form the spray cavity 15. The inner wall of the spray cavity 121 is inclined relative to the axis of the spray port 122. It can be easily understood that when the fire-fighting water in the spray cavity 121 is sprayed out of the spray port 122, the high-pressure fire-fighting water is sprayed out at an angle relative to the axis of the spray port 122, and the reaction force of the high-pressure fire-fighting water on the nozzle body 12 pushes the nozzle body 12 to rotate relative to the installation pipe 11. In addition, the inclined spray of the fire-fighting water can expand the spray range 50.
[0038] Please refer to Figure 4 In another alternative embodiment, the number of spray ports is multiple. The multiple spray ports are arranged around the fire condition detecting member. The spray direction of the spray port forms an angle with the radial direction of the rotary nozzle. Specifically, the spray port is arranged on the side wall of the rotary nozzle. The spray port is formed by opening a hole on the side wall of the rotary nozzle. It should be noted that the radial direction of the rotary nozzle refers to the direction from the rotation center of the rotary nozzle to the periphery of the rotary nozzle. It can be understood that the spray of the fire-fighting water by the spray port provides a reaction force on the rotary nozzle in the opposite direction of the spray direction. The tangential component of the reaction force on the side wall of the rotary nozzle causes the rotary nozzle to rotate circumferentially. In this embodiment, the direction of the spray port is adjusted so that the rotary nozzle can rotate under the reaction force of the water spray without the need for an additional motor drive.
[0039] Alternatively, the spray direction of the spray port in this embodiment is in the horizontal plane. In other embodiments, the spray direction of the spray port can be arranged at an angle with the horizontal plane. It is only necessary to ensure that the projection of the spray direction of the spray port on the horizontal plane forms an angle with the radial direction of the rotary nozzle.
[0040] Please refer to Figure 1In order to fix the fire detection element 20, the intelligent fire detection sprinkler 100 further comprises a fixing frame 30. One end of the fixing frame 30 is used for installing the fire detection element 20, and the other end of the fixing frame 30 is connected with the installation pipe 11. It can be understood that the end of the fixing frame 30 used for installing the fire detection element 20 is fixedly arranged at the spray opening 122, so that the sensing head of the fire detection element 20 and the spray opening 122 are arranged in the same plane. The fixing frame 30 is internally provided with a lead cavity 31. The lead cavity 31 is used for accommodating a lead 32. One end of the lead 32 is electrically connected with the fire detection element 20. The other end of the lead 32 extends out of the installation pipe 11 along the fixing frame 30, and is used for wiring the fire wire detector. It can be understood that the fixing frame 30 is located inside the spray cavity 15, and can isolate the fire-fighting water, so as to facilitate the electrical connection of the fire detection element 20 in the spray cavity 15. Further, it can be understood that the fixing frame 30 is fixedly connected with the installation pipe 11, so that the wiring end of the lead 32 is fixed, and when the rotary sprinkler 10 rotates, the wire harness located outside the installation pipe 11 is prevented from being wound.
[0041] Further, one end of the fixing frame 30 close to the installation pipe 11 is provided with a connector 33. The end of the lead 32 away from the fire detection element 20 is connected with the connector 33. It can be understood that when the fire connector needs to be electrically connected, only the external wire harness needs to be connected with the connector 33. The installation of the connector 33 can relatively close the lead 32 inside the fixing frame 30, so as to prevent the lead 32 from being damaged.
[0042] Further, one end of the fixing frame 30 close to the installation pipe 11 is provided with a connector 33. The end of the lead 32 away from the fire detection element 20 is connected with the connector 33. It can be understood that when the fire connector needs to be electrically connected, only the external wire harness needs to be connected with the connector 33. The installation of the connector 33 can relatively close the lead 32 inside the fixing frame 30, so as to prevent the lead 32 from being damaged.
[0043] The fire detection element 20 is an infrared sensor or an ultraviolet sensor, which can detect infrared rays or ultraviolet rays generated when the fire occurs, and send a fire generation signal. When the fire is extinguished, a fire extinguishing signal can be sent. In the embodiment, an infrared sensor with smaller volume is adopted. In other embodiments, an ultraviolet sensor or a smoke sensor can also be arranged, which can detect the fire.
[0044] Second embodiment
[0045] Please refer to Figure 3The embodiment provides a spray fire extinguishing system 200, which comprises the intelligent fire detecting spray head 100 of the first embodiment and a fire water pipe 201. The fire water pipe 201 is used for supplying water to the intelligent fire detecting spray head 100. The fire water pipe 201 is fixed above a ceiling 203. Specifically, in the embodiment, the fire water pipe 201 is fixed on a top wall of the room through a fixing support 204. The ceiling 203 is used for shielding the fire water pipe 201 and plays a decorative role. The intelligent fire detecting spray head 100 extends out of the ceiling 203 and is located below the ceiling 203. It can be understood that the intelligent fire detecting spray head 100 is used for detecting a fire condition below the ceiling 203, that is, in the room. When a fire occurs, the intelligent fire detecting spray head 100 is used for spraying downward.
[0046] In the embodiment, the fire water pipe 201 is provided with an overhauling valve 205 and a valve 202. When the intelligent fire detecting spray head 100 fails, the overhauling valve 205 is closed, water supply is stopped, and the intelligent fire detecting spray head 100 is maintained or replaced. The valve 202 is used for supplying water to the intelligent fire detecting spray head 100 in normal use or stopping water supply.
[0047] Further, the spray fire extinguishing system 200 of the embodiment further comprises a control box 206. The control box 206 is electrically connected with the valve 202 and the intelligent fire detecting spray head 100. Specifically, the valve 202 is an electromagnetic valve. The control box 206 is electrically connected with the valve 202. Meanwhile, the control box 206 is electrically connected with the flame detector. In the embodiment, one end of the control box 206 is connected with the connector 33 on the mounting pipe 11 through a wire harness. When a fire occurs, the fire condition detecting piece 20 detects the flame generation and sends a flame generation signal to the control box 206, the control box 206 sends an opening signal to the valve 202, the valve 202 is opened, the rotary spray head 10 sprays to extinguish the fire. When the flame is extinguished, the fire condition detecting piece 20 sends a flame extinguishing signal to the control box 206, the control box 206 sends a closing signal to the valve 202, the valve 202 is closed, water supply is stopped, and the rotary spray head 10 stops spraying.
