In order to enable personnel in a building to quickly and accurately observe an escape arrow, specifically, the escape indication module 23 includes a laser 231 for emitting an arrow mark beam, the laser 231 is fixedly installed inside the emergency fire extinguishing unit 2, when the laser 231 is started, the laser 231 vertically emits an arrow mark beam downwards, the arrow mark beam can be clearly projected on the ground of an escape route, a lens 232 is fixedly installed below the laser 231, a metal film 233 for splitting the arrow mark beam and a reflector 234 for adjusting the projection direction of the arrow mark beam are installed inside the lens 232 to split the arrow mark beam into a plurality of arrow mark beams and project the arrow mark beams onto the escape route and the route wall, as shown in fig. 14, the number of the metal films 233 is two, the arrow mark projected downwards by the laser 231 passes through the lens 232 and the two metal films 233, at this time, the two metal films 233 split the arrow mark to two sides respectively, and the reflector 234 is matched to project the arrow mark light beam onto the channel wall (as shown in fig. 11-13), and the technology of splitting the light beam by the metal films 233 is the prior art, which is not a necessary technical feature of the present invention, and therefore is not described in detail, and in addition, in order to make the arrow mark light beam more striking, the arrow mark light beam emitted by the laser 231 may flash at a certain frequency.
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;
when a fire occurs, in order to avoid that the external line of the emergency fire extinguishing unit 2 is blown out by a big 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 needs to be automatically disconnected, and the emergency power supply 4 supplies power to the emergency fire extinguishing unit 2 for operation;
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 first wire 9 and the second wire 10 which are disconnected are arranged in 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 in the interior of the water pipe 222 is connected with the slider 8 through the first spring 7 in a sliding manner, the support column 6 above the slider 8 is connected with the first movable plate 11 through the second spring 13 in a sliding manner, and the inner side wall of the first movable plate 11 is provided with the first conductor 12 communicated with the first wire 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 external circuit and the emergency power supply 4 supply power to the emergency fire extinguishing unit 2 and switch the state:
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;
