In order to avoid the circuit interruption of the emergency fire extinguishing unit 2 in a fire, specifically, a standby power supply 4 is arranged inside the emergency fire extinguishing unit 2, as shown in fig. 4-5, when the circuit is interrupted in the fire, the standby power supply 4 supplies power to the electric elements inside the emergency fire extinguishing unit 2, so as to ensure the power supply;
the emergency fire extinguishing unit 2 is normally standby (only during the process of monitoring fire), the emergency fire extinguishing unit 2 is powered by an external line, but when the fire occurs, in order to avoid that the external line of the emergency fire extinguishing unit 2 is blown by fire (as shown in fig. 15 and 16, WBXL represents the external line), the line lap joint causes the burning out of the electrical elements inside the emergency fire extinguishing unit 2, the external line is required to be automatically disconnected, and the emergency fire extinguishing unit 2 is powered by the standby power supply 4;
therefore, the device can be additionally provided with a structure capable of disconnecting the external line from the standby power supply 4, specifically, the water pipe 222 is led into the interior of the suspension rod 17, the support column 6 is inserted into the interior of the suspension rod 17, the disconnected first lead 9 and the disconnected second lead 10 are arranged inside the support column 6, one end of the support column 6 is inserted into the interior of the water pipe 222 (as shown in fig. 9), the support column 6 positioned inside the water pipe 222 is slidably connected with the slider 8 through the first spring 7, the support column 6 above the slider 8 is slidably connected with the first movable plate 11 through the second spring 13, and the inner side wall of the first movable plate 11 is provided with the first conductor 12 communicated with the first lead 9; a second movable plate 14 is connected to the supporting column 6 below the slider 8 in a sliding manner through a third spring 16, and a second conductor 15 communicated with the second lead 10 is arranged on the inner side wall of the second movable plate 14;
the state of power supply switching of the emergency fire extinguishing unit 2 corresponding to the external circuit and the standby power supply 4 is as follows:
the first state: when the emergency fire extinguishing unit 2 is in a standby state, the water inside the water pipe 222 is in a static state, at this time, the slider 8 is subjected to upward elastic force of the first spring 7, the slider 8 pushes the first movable plate 11 to slide upwards (the second spring 13 is in a compressed state), so that the first conductor 12 connects the first conducting wire 9 (as shown in fig. 15), the external circuit supplies power to all the electrical elements inside the emergency fire extinguishing unit 2 for operation, at this time, the second conducting wire 10 is in an off state, and the standby power supply 4 does not work;
and a second state: when the fire detection module 21 detects a fire, the water pipe 222 conveys liquid to the high-pressure nozzle 221, at this time, the slider 8 receives downward water impact force (as shown by an arrow in fig. 10), so that the slider 8 slides downward against the elastic force of the first spring 7, the upward jacking force of the slider 8 on the first movable plate 11 is eliminated, the elastic force of the second spring 13 drives the first movable plate 11 to reset and slide downward, so that the first conductor 12 is disconnected from the first conducting wire 9, at this time, the external circuit is in a disconnected state, during the sliding process, the slider 8 slides downward against the second movable plate 14 (the third spring 16 is in a compressed state), so that the second conductor 15 connects the second conducting wire 10 (as shown in fig. 16), and the standby power supply 4 starts to supply power to all the electrical components inside the emergency fire extinguishing unit 2;
