Abstract
The utility model provides a fault alarm device for an open-circuit type air respirator and belongs to the technical field of safe labor protection. The utility model aims to provide an acousto-optic alarm device which can send out alarming signals when the open-circuit type air respirator is in failure or the quality of sucked air can not reach a standard. The open-circuit type air respirator comprises a controller, a combustible gas monitoring probe, a poisonous gas monitoring probe, a pressure sensor, an acousto-optic alarm, and a portable wireless acousto-optic alarm. The fault alarm device for the open-circuit type air respirator can monitor the concentration of combustible gases and poisonous gases nearby the gas inlet of the open-circuit air respirator, and monitors the pressure of compressed air in the open-circuit type air respirator; when the concentration of the combustible gases or the poisonous gases nearby the gas inlet exceeds a standard value or the pressure of the compressed air is lower than the set value of the open-circuit type air respirator, the acousto-optic alarm and the portable wireless acousto-optic alarm send out acousto-optic alarming signals for prompting operators.
Description
Technical field
The utility model belongs to safe labour protection field; relate to open type air respiratorresuscitator accident warning device, specifically when open type air respiratorresuscitator breaks down shutdown or air amount quality dissatisfaction, can send a kind of device that sound and light alarm signal reminds operating personnel to note.
Background technology
In the daily productions of industrial department such as oil, chemical industry, boats and ships, metallurgy and building materials and the emergency repair disaster relief, the use of open type air respiratorresuscitator is more and more extensive.But the restriction due to environment for use, the air inlet air quality of open type air respiratorresuscitator is very unstable, often there is the phenomenon that toxic gas or fuel gas exceed standard, as reminded not in time operating personnel's aborting job, can damage respirator user of service's health.And the power set of open type air respiratorresuscitator also may break down, the interruption that causes breathe air to be supplied with, as informed not in time, operating personnel withdraws, and asphyxiation hazard may occur.
Summary of the invention
The purpose of this utility model is to provide a kind of acoustic-optic alarm, and this device can send sound and light alarm signal when open type air respiratorresuscitator breaks down shutdown or air amount quality dissatisfaction.
The technical solution of the utility model is as follows:
Open type air respiratorresuscitator accident warning device of the present utility model comprises controller, combustible gas monitoring probe, monitoring poisonous gas probe, pressure sensor, audible-visual annunciator, portable radiotelephone audible-visual annunciator.The cable that passes through of combustible gas monitoring probe, monitoring poisonous gas probe, pressure sensor and audible-visual annunciator is connected with controller, and controller is communicated with portable radiotelephone audible-visual annunciator by radio signal.Controller has wireless signal transmission antenna, when monitoring the abnormal signal that combustible gas monitoring probe, monitoring poisonous gas probe and pressure sensor are transmitted, except by cable to audible-visual annunciator sends enabling signal, also to portable radiotelephone audible-visual annunciator, send radio enabling signal.Audible-visual annunciator and portable radiotelephone audible-visual annunciator send sound and light alarm signal after receiving enabling signal.
The beneficial effects of the utility model are, can monitor open type air respiratorresuscitator air inlet neighbouring combustable gas concentration and concentration of toxic gases, and the compressed-air actuated pressure of open-circuit formula air respiratorresuscitator is monitored, near combustable gas concentration air inlet or the concentration of toxic gases value of being above standard, or when compressed-air actuated pressure sets value lower than open type air respiratorresuscitator, audible-visual annunciator and portable radiotelephone audible-visual annunciator send sound and light alarm signal, remind in time operating personnel.
Accompanying drawing explanation
Fig. 1 is formation schematic diagram of the present utility model.
Each parts in figure: 1. controller, 2. combustible gas monitoring probe, 3. monitoring poisonous gas probe, 4. pressure sensor, 5. audible-visual annunciator, 6. portable radiotelephone audible-visual annunciator.
The specific embodiment
embodiment mono-:
(1) controller of the utility model open type air respiratorresuscitator accident warning device is switched on power, (2) combustible gas monitoring probe and (3) monitoring poisonous gas are popped one's head in and be fixed near open type air respiratorresuscitator air inlet, (4) pressure sensor is arranged on the compressed air conveying pipeline of open type air respiratorresuscitator, (5) audible-visual annunciator is placed on air respiratorresuscitator operating personnel visible location, and (6) portable radiotelephone audible-visual annunciator is carried by operating personnel.
Open (1) controller power source, wait for that (2) combustible gas monitoring probe and the preheating of (3) monitoring poisonous gas probe complete, device enters duty, and operating personnel can start operation.
When the fuel gas of open type air respiratorresuscitator air inlet or toxic gas exceed standard, or open type air respiratorresuscitator breaks down, cause the gas pressure in supply air line to be less than while setting value, (5) (6) portable audible-visual annunciator that audible-visual annunciator and operating personnel carry sends sound and light alarm signal, reminds operating personnel to withdraw rapidly deathtrap.
After the end of job, closing controller power supply, this open type air respiratorresuscitator accident warning device quits work.
Claims (2)
1. open type air respiratorresuscitator accident warning device, comprise controller, combustible gas monitoring probe, monitoring poisonous gas probe, pressure sensor, audible-visual annunciator, portable radiotelephone audible-visual annunciator, it is characterized in that: the cable that passes through of combustible gas monitoring probe, monitoring poisonous gas probe, pressure sensor and audible-visual annunciator is connected with controller, and controller is communicated with by radio signal with portable radiotelephone audible-visual annunciator.
2. open type air respiratorresuscitator accident warning device according to claim 1, it is characterized in that controller has wireless signal transmission antenna, when monitoring the abnormal signal that combustible gas monitoring probe, monitoring poisonous gas probe and pressure sensor are transmitted, except by cable to audible-visual annunciator sends enabling signal, also to portable radiotelephone audible-visual annunciator, send radio enabling signal.
