Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguishing devices, and in particular relates to an intelligent device for starting a fire extinguishing agent based on a driven thermal line. Background Art

[0002] Existing communication equipment cabinets, various electrical cabinets, cabinets with fire hazards, relatively closed pipeline corridors, small warehouses, small spaces for transportation and power, etc. are most likely to have fire hazards, and are also most likely to cause property losses and even endanger people's lives due to fires caused by circuit short circuits such as old cables. These places still attach great importance to fire protection, but because there are many points to be deployed, from the perspective of cost and electrical characteristics of the venue, etc., generally, S-type aerosol (or perfluorohexanone, etc.) fire extinguishing devices with thermal wires are installed. The thermal wires are ignited by the fire source to start the S-type aerosol (or perfluorohexanone, etc.) to spray gas diffuse fire extinguishing agents for automatic fire extinguishing.

[0003] This method of automatically extinguishing fire by installing an S-type aerosol (or perfluorohexanone, etc.) with a heat-sensitive wire, igniting the heat-sensitive wire through the fire source to start the S-type aerosol (or perfluorohexanone, etc.) to spray the fire extinguishing agent, has the following problems:

[0004] First, the activation condition of the thermistor line is that the fire source reaches (180±10)℃ before it can be ignited. To achieve such conditions in the cabinet, the fire has already occurred and the fire is already very fierce and even affects the surrounding equipment or environment. Even if the S-type aerosol (or perfluorohexanone, etc.) is successfully activated to spray and extinguish the fire, the effect is very limited or even ineffective!

[0005] Second, this fire-fighting method involves passively igniting a thermal wire to activate the fire extinguishing agent. This method is based on the discovery and disposal of fires in the later stages, and cannot resolve fires in the best discovery and disposal period when fires are in their infancy. This method cannot effectively deal with the occurrence of fires.

[0006] Third, this type of fire-fighting method has been installed in many monitoring sites for many years, but it is a post-treatment device. If it is removed and some more advanced early warning monitoring and fire-fighting devices with "early detection and early treatment" functions are installed, the cost will inevitably increase. Utility Model Content

[0007] The utility model aims to provide an intelligent device for starting a fire extinguishing agent based on driving a thermal wire, so as to solve the problem that the fire extinguishing device with a thermal wire conventionally installed in the existing cabinet cannot provide fire warning and handle the fire in time.

[0008] The technical solution adopted by the utility model is as follows:

[0009] An intelligent device for starting a fire extinguishing agent based on driving a thermistor line comprises a device body installed in a cabinet, the device body comprises an MCU main control module, the MCU main control module is electrically connected to a CO gas detection module, the MCU main control module is electrically connected to a smoke detection module, the MCU main control module is also electrically connected to a heating wire drive circuit, and the heating wire drive circuit is electrically connected to a heating wire.

[0010] Furthermore, the heating wire driving circuit is provided in multiple groups.

[0011] Furthermore, the CO gas detection module is a CO gas detector.

[0012] Furthermore, the dense smoke detection module is a smoke detector.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the heating wire is connected to the thermistor line of the aerosol (or perfluorohexanone) fire extinguishing device with a thermosensitive wire originally installed in the cabinet. The MCU main control module monitors the CO gas generated by the smoldering of the fire hazard in the cabinet and the thick smoke generated by the smoldering or burning of the fire hazard based on the CO gas detector and the smoke detector. After detecting the typical characteristics of these fire hazards, the MCU main control module determines that a fire hazard has occurred or a fire has occurred, and relies on the heating wire driving circuit to heat the heating wire, triggering the aerosol (or perfluorohexanone) fire extinguishing device with a thermosensitive wire originally installed in the cabinet, and actively spraying the fire extinguishing agent to extinguish the fire. Without disassembling the original fire extinguishing device in the cabinet, the fire protection system function is upgraded at a relatively low cost, which not only solves the problem of continued reuse of the original fire extinguishing device, but also achieves the purpose of early discovery of fire hazards, early warning, active disposal of fires, and avoidance of fires, and effectively solves the problem that the fire extinguishing device with a thermosensitive wire conventionally installed in the existing cabinet cannot provide fire warning and untimely disposal of fires.

[0015] 2. In the utility model, a plurality of groups of heating wire driving circuits are provided, and corresponding heating wires are provided, so that the aerosol (or perfluorohexanone) fire extinguishing device with thermistor wire originally installed in the multi-channel cabinet can be externally controlled to realize the linkage control and driving of the fire extinguishing device.

[0016] 3. In the present invention, the MCU main control module can make a comprehensive judgment through a preset program combined with the detected information to achieve early prediction of the fire situation and graded warning, and actively trigger the original fire extinguishing device to spray fire extinguishing agent to implement fire extinguishing according to the fire situation.
