Embodiment
Below with reference to the drawings and the specific embodiments, the utility model is elaborated.
As shown in Figure 1, the utility model intelligent environment protection gas cabinet comprises cabinet 10, sensor unit, controller 40, alarm unit and clean unit 70.
Described cabinet 10 is for loading gas cylinder 20, and in the present embodiment, described cabinet 10 can load two gas cylinders 20, and one of them is as main gas cylinder, and another is as bailout bottle, and each gas cylinder 20 is connected to steam line 30 by a lateral 32, outwards carries gas.On described each lateral 32, be connected with an electronic valve 50, described electronic valve 50 is connected with controller 40, and controller 40 is controlled the unlatching of described electronic valve 50 or closed, and makes described lateral 32 be communicated with or end.Understandably, in described cabinet 10, also can only load single air cylinder 20 or more gas cylinder 20.When use, open Single Electron valve 50, outwards carry gas with the gas cylinder 20 that this electronic valve 50 is connected as main gas cylinder, other electronic valve 50 cuts out, and other corresponding gas cylinder 20 is as bailout bottle.For avoiding gas cylinder 20 to rock in cabinet 10, in described cabinet 10, be provided with the fixing described gas cylinder 20 of fixed plate 12, corresponding each gas cylinder 20, forms a breach 14 matching with the profile of gas cylinder 20 and locates gas cylinder 20 on described fixed plate 12.
Described sensor unit is arranged in cabinet 10, comprises multiple sensors, as baroceptor 52, concentration sensor 54 and saturation ratio sensor 56; Described sensor unit is connected with controller 40 and detection architecture is exported to controller 40; Described alarm unit is connected with controller 40, comprise multiple alarms, as air pressure alarm 62, concentration alarm 64 and saturation ratio alarm 66, described in controller 40 analysing and processing sensor unit the testing result of baroceptor 52, concentration sensor 54 and saturation ratio sensor 56, in the time that any testing result exceeds predetermined value, start the warning of corresponding air pressure alarm 62, concentration alarm 64 or saturation ratio alarm 66.
Described baroceptor 52 is for detecting in real time the air pressure in gas cylinder 20, and each gas cylinder 20 is equipped with a baroceptor 52.In the present embodiment, described baroceptor 52 is 2, is installed on respectively on the lateral 32 of a corresponding gas cylinder 20.Each baroceptor 52 is all connected and connects respectively a barometer 60 with controller 40, on each barometer 60, connect an air pressure alarm 62, baroceptor 52 is passed to the pressure information of the corresponding gas cylinder 20 detecting corresponding barometer 60 and show barometer reading on barometer 60.When the air pressure in gas cylinder 20 is during lower than setting value, controller 40 starts air pressure alarm 62 flickers reports to the police, and gas cylinder 20 is changed in prompting; The electronic valve 50 of cutting out with Time Controller 40 on the lateral 32 of the former gas cylinder 20 as main gas cylinder air feed blocks air feed, and open the electronic valve 50 on the lateral 32 of former another gas cylinder 20 as bailout bottle, continue air feed by another gas cylinder 20, thereby realize continual air feed.
Described concentration sensor 54 is installed in cabinet 10, for detecting in real time the gas concentration in cabinet 10, checks whether gas cylinder 20 exists leakage.The gas that described clean unit 70 is revealed for purifying gas cylinder 20, the top that it is installed on cabinet 10, comprises gas purifier 72 and blower fan 74.Corresponding described blower fan 74, described cabinet 10 can be provided with corresponding opening, described blower fan 74 is arranged at described opening, and the exhaust outlet of blower fan 74 can be connected with ventilation duct 76, and blower fan 74 runnings are extracted the gas in cabinet 10 out and are expelled to outdoor by ventilation duct 76.
Described gas purifier 72 is arranged in cabinet 10 and is positioned at the wind inlet position of blower fan 74, is provided with the scavenging material of porous structure in gas purifier 72, as active carbon etc., and the gas of revealing for adsorbing the interior gas cylinder 20 of cabinet 10.Described saturation ratio sensor 56 is arranged in gas purifier 72, for detection of the saturation ratio of the scavenging material of gas purifier 72, in the time that saturation ratio sensor 56 detects that the saturation ratio of the scavenging material of described gas purifier 72 exceedes predetermined value, controller 40 starts saturation ratio alarm 66 and points out caretaker to change in time scavenging material, to ensure the purification function of clean unit 70.
Described concentration sensor 54 is connected with controller 40, the gas concentration information detecting is passed to controller 40, in the present embodiment, described concentration sensor 54 is frequency alarm device, described controller 40 is connected with the blower fan 74 of concentration alarm 64 and clean unit 70 by relay, and with the running of controlling blower fan 74 whether the gas concentration information detecting according to concentration sensor 54 folding that carrys out control relay.According to relay, the folding frequency within the time period of setting shows the startup frequency of blower fan 74 in the mode of flicker to described concentration alarm 64, and caretaker judges the gas leakage situation of gas cylinder 20 according to the flicker frequency of concentration alarm 64.
As shown in the above, the utility model intelligent environment protection gas cabinet can be realized the Real-Time Monitoring of the air pressure to gas cylinder 20 by baroceptor 52, controller 40, electronic valve 50, air pressure alarm 62, in the time that gas cylinder 20 air pressure are not enough, automatic alarm reminds administrative staff to change in time air bottle 20, and the gas cylinder 20 that automatically switches continues air feed, ensure that the continuity of air feed is flat; In addition, can realize the Real-Time Monitoring to the gas concentration in cabinet 10 by concentration sensor, controller 40, blower fan 74, concentration alarm 64, judge whether gas cylinder 20 is revealed, convenient maintenance, in the time of Leakage Gas, start blower fan 74 gas in cabinet 10 is extracted out, make gas in cabinet 10 all the time in comparatively safe environment; Again in addition, be provided with gas purifier 72 at the wind inlet of described blower fan 74 and purify the gas of revealing, can avoid the harmful gas that gas cylinder 20 is revealed to be got rid of to the external world by blower fan 74, to environment; Again in addition, described gas purifier 72 is also connected with saturation ratio sensor 56, described saturation ratio sensor 56, controller 40 and saturation ratio alarm 66, realize the real-time monitoring of the saturated conditions of the scavenging material to purifier 72, and saturation ratio exceed predetermined value alarm remind caretaker change in time scavenging material, ensure purifying effect, guarantee that the gas that blower fan 74 is discharged does not pollute the environment.
So, the utility model intelligent environment protection gas cabinet can be implemented intelligentized management: adopt baroceptor 52 and electronic valve 50 to realize the intelligent conversion to gas cylinder 20, ensure continuous air feed; Adopt gas purifier 72 that the leakage gas in cabinet 10 is removed and purified, realized environment protection effect; Adopt concentration sensor 54 and blower fan 74, the gas leakage situation of gas cylinder 20 is monitored, in the time that the gas concentration in cabinet 10 reaches finite concentration, just start blower fan 74 and turn round, realized energy-saving effect.It should be noted that; the utility model is not limited to above-mentioned mode of execution; according to creative spirit of the present utility model; those skilled in the art can also make other variations; the variation that these do according to creative spirit of the present utility model, within all should being included in the utility model scope required for protection.
