Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is that the carbon-dioxide fire engine sacurity alarm system of the utility model milling equipment is formed block scheme.
Fig. 2 is the carbon-dioxide fire engine sacurity alarm system control principle block scheme of the utility model milling equipment.
Embodiment
Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of carbon-dioxide fire engine sacurity alarm system, structure, feature and the effect thereof according to the milling equipment that the utility model proposes, describe in detail as after.
See also Fig. 1, this milling equipment carbon-dioxide fire engine sacurity alarm system 100 is to improve on original fire automatic fire extinguishing system basis, and original fire automatic fire extinguishing system comprises " venting is not gone into " pilot lamp 31 and the acoustooptic alarm 32 in the smothering zone of Fire Autoalarm 3 in the fire self-extinguishing switch board and cabinet top rotating light 2 thereof, first LED display, carbon-dioxide fire engine bottle group, nitrogen steel cylinder, pressure switch, device fabrication line.The carbon-dioxide fire engine sacurity alarm system 100 of this milling equipment of the present utility model comprises this automatic alarm controller 3 and the cabinet top rotating light 2 thereof in this original fire self-extinguishing switch board, gas concentration lwevel automatic tester 10, control module 20, alarm device 30, LED display 40 is the general designation of this first LED display or this second LED display among first LED display or second LED display 40(Fig. 1) and connection line, as shown in Figure 1, this gas concentration lwevel automatic tester 10 is installed in the fire extinguishing zone, alarm device can utilize fire extinguishing zone " venting is not gone into " pilot lamp 31 and acoustooptic alarm 32 outdoors of original fire automatic fire extinguishing system, also alarm device can be installed separately; This second LED display 40 is newly added equipment, also can utilize original this first LED display to improve; The control module of newly establishing 20 is installed in original self-extinguishing switch board 1, its technical indicator accomplishes to carry out compatibility with original automatic alarm control system fully, and this control module 20 is electrically connected respectively with LED display 40, gas concentration lwevel automatic tester 10, " venting is not gone into " pilot lamp 31 and acoustooptic alarm 32.
The carbon-dioxide fire engine sacurity alarm system 100 of this milling equipment has automatic detection, reports to the police and the LED Presentation Function automatically, and the warning system control principle as shown in Figure 2.
See also Fig. 1 and Fig. 2, when fire takes place, Fire Autoalarm 3 in original fire automatic fire extinguishing system is sent alerting signal, the LED display 40 that starts production equipment master OPS shows " so-and-so regional gas concentration lwevel higher personnel do not enter ", and starts this zone " venting is not gone into " pilot lamp 31 and acoustooptic alarm 32 outdoors.Simultaneously; when gas concentration lwevel automatic tester 10 detects flame failure protection district concentration of carbon dioxide arrival dangerous values; gas concentration lwevel automatic tester 10 also can output alarm signal; to self-extinguishing switch board 1 interior this control module 20; start the rotating light 2 on the switch board 1, the LED display 40(demonstration " so-and-so regional gas concentration lwevel higher personnel do not enter " of production equipment main operation pulpit), and start this zone " venting is not gone into " pilot lamp 31 and acoustooptic alarm 32 outdoors.Perhaps, not breaking out of fire, as the CO valve leak takes place, at this moment, when concentration of carbon dioxide arrives dangerous values in gas concentration lwevel automatic tester 10 detects the zone, gas concentration lwevel automatic tester 10 also can output alarm signal, to self-extinguishing switch board 1 interior this control module 20, start the rotating light 2 on the switch board 1, the LED display 40(of production equipment main operation pulpit shows " so-and-so regional gas concentration lwevel higher personnel do not enter "), and start this zone " venting is not gone into " pilot lamp 31 and acoustooptic alarm 32 outdoors.
Fire extinguishing finishes, artificial mandatory the automatic fire alarm control system is resetted, and at this moment the All Ranges sound and light alarm is removed.But; when fire self-extinguishing switch board 1 inner control module 20 receives " high concentration carbon dioxide warning " signal of gas concentration lwevel automatic tester 10 outputs; the rotating light 2, the production equipment master that start on the switch board 1 are controlled the indoor LED display 40 of system; this LED display shows " so-and-so put out a fire the higher personnel of regional gas concentration lwevel do not enter " and " venting is not gone into " pilot lamp 31 and the audible-visual annunciator 32 that starts this protection zone.
In case the gas concentration lwevel in the fire extinguishing zone falls the end during to safety value; gas concentration lwevel detector 10 will be removed alerting signal to this control module 20; " so-and-so put out a fire the higher personnel of regional gas concentration lwevel do not enter " that cause the rotating light 2 on switch board 1 top to extinguish, the production equipment master control that the indoor LED display of system 40 shows disappears, and " venting is not gone into " pilot lamp 31 of this protection zone and " acoustooptic alarm " 32 recover normal operating conditionss automatically.Maintainer's relieved safe work in this zone of can freely coming in and going out.
In sum, the carbon-dioxide fire engine sacurity alarm system of milling equipment of the present utility model not only can guarantee original automatic fire alarm function, has increased the warning function to high concentration carbon dioxide simultaneously, has guaranteed personnel's safety.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
