Referring to fig. 1, the present embodiment provides an extremely early automatic fire extinguishing apparatus 100, mainly comprising a detection module 110, a control module 120 and a fire extinguishing module 130, wherein the detection module 110 comprises a suction pump 111, a detection chamber 112, and a smoke detector 113 and a CO detector 114 disposed in the detection chamber 112. The control module 120 includes a main control circuit board 121 connected to the smoke detector 113 and the CO detector 114. The fire extinguishing module 130 includes a fire extinguishing container 131 for containing fire extinguishing agent, a release pipe 132 for releasing fire extinguishing agent, and a valve 133 connected between the fire extinguishing container 131 and the release pipe 132 for controlling release of fire extinguishing agent; the suction pump 111 sucks air in the protected space into the detection chamber 112, the smoke detector 113 and the CO detector 114 detect the concentration of smoke particles and the CO content in the air respectively, the main control circuit board 121 sends out a fire extinguishing signal when the concentration of smoke particles and/or the CO content exceeds the standard, and controls the valve 133 to open, so that the fire extinguishing agent is released through the release pipe 132, a nozzle is arranged on the release pipe 132, and the fire extinguishing agent is sprayed out at a high speed through the nozzle to extinguish the fire source.
The above-mentioned detection module 110 adopts the suction pump 111, the detection chamber 112 and the smoke detector 113 and the CO detector 114 disposed in the detection chamber 112 to detect fire, which belongs to active fire detection, and continuously sucks ambient air through the suction pump 111, if fire occurs, the smoke detector 113 and the CO detector 114 can sensitively detect the concentration of smoke particles in the air and the CO content even if the fire source is in the initial smoldering stage, and when the concentration of smoke particles and the CO content exceed the standard, the main control circuit board 121 in the control module 120 determines that fire has occurred, and simultaneously sends out a fire extinguishing signal to control the fire extinguishing module 130 to release the fire extinguishing agent for extinguishing fire.
The embodiment adopts the active fire detection technology, can realize extremely early automatic detection, automatic fire confirmation and automatic fire extinguishing, eliminates fire hidden danger in smoldering stage, greatly reduces the occurrence rate of fire accident, and effectively ensures the life and property safety of people.
In addition, the fire extinguishing module 130 further includes a fire detecting device 134, where the fire detecting device 134 includes a fire detecting tube connected to the valve 133, and a glass tube that is easily broken by heat is connected to an end of the fire detecting tube, and the fire extinguishing agent is adapted to be released from the fire detecting tube after the glass tube is broken.
The fire detecting device 134 is a passive fire detecting and extinguishing device, and when a fire occurs, the surrounding air temperature is heated and raised, and the temperature sensing liquid in the glass tube is heated and expanded to squeeze and burst the glass tube. The glass tube is internally provided with a plug for blocking the outlet of the fire detection tube, so that the fire extinguishing agent in the fire detection tube cannot overflow, and when the glass tube bursts, the plug is extruded by the high-pressure fire extinguishing agent, and the fire extinguishing agent is sprayed out to extinguish the fire source, thereby achieving the aim of extinguishing the fire.
Meanwhile, the fire extinguishing module 130 further comprises a mechanical actuation device 135, the mechanical actuation device 135 comprising a button adapted to manually open the valve 133. When a person finds a fire but the very early automatic fire extinguishing apparatus of the present embodiment does not detect it, the person can open the valve 133 by pressing the button to spray the fire extinguishing agent from the release pipe 132, thereby performing a function of manually starting fire extinguishing.
Preferably, the valve 133 is a three-way solenoid valve, one of which is connected to the fire extinguishing container 131, one of which is connected to the release pipe 132, and the other of which is connected to the fire detecting pipe, and has an independent control function, so that when the smoke detector 113, the CO detector 114, the fire detecting device 134 and the mechanical starting device 135 detect a fire, the valves can be controlled respectively and opened appropriately to connect the required pipes for extinguishing the fire.
Therefore, in this embodiment, the signal input end of the main control circuit board 121 is respectively connected with the smoke detector 113, the CO detector 114, the fire detecting device 134 and the mechanical starting device 135, the signal output end is connected with the valve 133, and when all three of the smoke detector 113, the CO detector 114 and the fire detecting device 134 emit fire extinguishing signals, the main control circuit board 121 controls the valve 133 to only switch on one of the release pipe 132 and the fire detecting pipe; when the smoke detector 113, the CO detector 134 and the mechanical starting device 135 all emit fire extinguishing signals, the main control circuit board 121 controls the valve 133 to be connected with the release pipe 132. Thus, when both the active detection and the passive detection detect a fire, the valve 133 is only connected with one of the release pipe 132 and the fire detecting pipe, so that the waste of fire extinguishing agent is avoided, and meanwhile, the fire extinguishing effect is prevented from being influenced by too small pressure of the fire extinguishing agent caused by the simultaneous operation of the release pipe 132 and the fire detecting pipe. Similarly, when the smoke detector 113, the CO detector 114 and the mechanical starting device 135 all emit fire extinguishing signals, the main control circuit board 121 controls the valve 133 to be connected to the release pipe 132, and the fire extinguishing agent is released through the release pipe 132.
In addition, the control module 120 of the present embodiment further includes a power supply 122, where the power supply 122 is connected to and supplies power to the main control circuit board 121, the smoke detector 113, the CO detector 114, and the valve 133, respectively. Therefore, the very early automatic fire extinguishing apparatus 100 can normally detect fire and extinguish fire even if power fails without using an external power source, and can be placed in a place where no commercial power is set up, thereby having a wider range of applications.
In order to further improve the sensitivity of fire detection, the embodiment is further provided with a sampling pipe network in the detection chamber 112, the sampling pipe network is provided with a plurality of sampling holes, and the smoke enters the smoke detector 113 and the CO detector 114 through the sampling pipe network. The sampling pipe network is a specially calculated pipeline system with sampling holes on the pipeline, and the finally determined sampling hole diameter is verified by test effect. The smoke detector 113 and the CO detector 114 sense the air sucked into the sampling hole, and because the air in the sampling hole simulates the surrounding air environment, the concentration of smoke particles and the content of CO are completely the same as those in the surrounding air, thereby ensuring the detection accuracy, improving the detection sensitivity and avoiding the situations of false alarm and missing alarm.
Likewise, the smoke detector 113 in this embodiment adopts a blue-ray electronic filter screen detector, and the pore size of the filter screen can be adjusted by software, so that the interference such as dust and water vapor can be automatically removed, and the smoke detector has the characteristics of high sensitivity, strong false alarm preventing capability and the like. The CO detector 114 comprises an electrochemical sensor, a sensor assembly with a built-in microcontroller and a software linear compensation algorithm, and can detect CO content of 0-1000 ppm.
In addition, the early automatic fire extinguishing apparatus 100 of the present embodiment further has a feedback interface 123 for connecting with a conventional alarm system to alert a manager or related personnel that a fire has been detected and that the apparatus has automatically extinguished the fire, and a communication interface 124. The communication interface can be used for people in the fire scene to communicate with a manager or a fire department and report the current disaster situation or fire extinguishing situation so as to know the scene in time.
Through the selection and the arrangement of the hardware components, the air suction pump 111 is utilized to continuously pump air from the inside of the surrounding protection space to be sent into the detection chamber for detection, and compared with the traditional passive detector, the reaction time is 10-20 times faster, so that the fire can be effectively and timely extinguished, and the hidden danger of the fire can be eliminated.
