Description of drawings
Fig. 1 is the schematic diagram of a kind of portable cabin air ambient alarm of the utility model.
Embodiment
Below in conjunction with preferred embodiment, the utility model is described in further details.As shown in Figure 1, a kind of portable cabin air ambient alarm mainly comprises three parts, is respectively Portable alarm body, monitoring means and signal transmission device.
The Portable alarm body comprises oxygen sensor, switchgear, battery and alarm; The Portable alarm body can be arranged to the profile that cap, wrister or knapsack etc. are convenient to carry.
due to the different place of the frequent discrepancy of staff, working environment is complicated and changeable, one or more hazardous gas sensors are set merely and can't guarantee being perfectly safe of air ambient, only be provided with oxygen sensor on this alarm, only in the detecting air environment to the content of the most important oxygen of human body, after the first signal transmitter of the data that sensor is surveyed through being arranged on Portable alarm inside is transferred to monitoring means, compare with the program of storing in central processing unit, oxygen content in enclosure space is abnormal, sudden fast rush appears or when reducing suddenly, represent that unknown variation has occured air ambient, monitoring means calls the alarm program in central processing unit, send signal, the portable cabin air horn that the staff carries sends actuation of an alarm, the prompting staff breaks off an action, withdraw the scene.
This alarm is provided with abundant warning means, as the acoustic alarm device, and light crossing-signal and vibrations alarm, the staff can arrange according to different demands different warning means, with in the face of working environment complicated and changeable, really plays the effect of safety instruction.
In order to be convenient for carrying, alleviate the weight of alarm, the battery of Portable alarm has been selected the lithium ion battery of lightweight, lithium ion battery light and stablely also provide portion to ensure reliably for the normal operation of alarm and staff's safety.
Monitoring means can be arranged in ship control chamber or captain's cabin, and monitoring means comprises central processing unit, control device, power supply and liquid crystal display, and the secondary signal transmitter is connected with central processing unit, bears the effect that signal transmits and receives.Monitoring means has been set up liquid crystal display, has facilitated the visual of information, is convenient to reading and typing of information, has improved the work efficiency of monitoring means.
It is 0-40 ℃ in environment temperature, ambient atmosphere pressure is 80kPa-110kPa, in environment when surrounding air relative humidity is not more than 95%, a kind of portable cabin air ambient alarm, the scope of oxygen concentration can be set to 20%-21%, the oxygen content that detects when the Portable alarm body has exceeded this scope, sends at once alerting signal, reminds the staff to take care.
