Abstract
The utility model discloses a kind of anti-explosion fuel gas automatic alarm exhaust apparatus.It comprises the combustible gas probe for detecting gas leakage and the exhaust fan for getting rid of leakage combustion gas, and the air outlet of exhaust fan connects gas exhaust duct; Be provided with the audible-visual annunciator that can give the alarm according to the detection information of combustible gas probe in combustible gas probe, also comprise the sound and light controlled delay switch that can receive the alerting signal that audible-visual annunciator sends, sound and light controlled delay switch is connected with exhaust fan.After adopting above-mentioned structure, when combustible gas leakage, given the alarm by sound and light alarm after the combustion gas of combustible gas probe detecting leakage and warning information is transferred to sound and light controlled delay switch action, thus make vent fan work forced exhaust, be vented also continuous in the continuous situation of warning, thereby eliminate complete hidden danger.
Description
Technical field
The utility model relates to a kind of device for preventing to warn gas leakage, specifically a kind of anti-explosion fuel gas automatic alarm exhaust apparatus.
Background technology
The inflammable gas of clean energy resource is widely used in daily life, bring very large facility, meanwhile, due to inflammable gas colorless and odorless, not easily discover just in case leak, inflammable gas also has inflammable and explosive characteristic simultaneously, meet naked light (walk about and produce electrostatic) and will heavy explosion be caused, make it have very large harmfulness, a domestic liquified gas bomb brisance is equivalent to 3000 antitank grenades, 150 kilograms of TNT explosives, restaurant, restaurant are larger by large-scale liquid gas storage tank brisance, can explode a few floor that collapses; Such as: blast in 6.11 office building dining rooms, Suzhou one home fuel gas company living quarters, cause three layers of office building of about 400 squares to cave in, imbed 20 people, dead more than half, its extent of injury has some idea of.
Summary of the invention
Technical matters of the present utility model is to provide a kind of anti-explosion fuel gas automatic alarm exhaust apparatus that can detect combustible gas leakage and also eliminate safe hidden trouble in real time.
In order to solve the problems of the technologies described above, anti-explosion fuel gas automatic alarm exhaust apparatus of the present utility model, comprises the combustible gas probe for detecting gas leakage and the exhaust fan for getting rid of leakage combustion gas, and the air outlet of exhaust fan connects gas exhaust duct; Be provided with the audible-visual annunciator that can give the alarm according to the detection information of combustible gas probe in combustible gas probe, also comprise the sound and light controlled delay switch that can receive the alerting signal that audible-visual annunciator sends, sound and light controlled delay switch is connected with exhaust fan.
The height of described gas exhaust duct is more than 5 meters.
Described exhaust fan is provided with manual switch.
After adopting above-mentioned structure, due to the combustible gas probe arranged, sound and light controlled delay switch and exhaust fan, when combustible gas leakage, given the alarm by sound and light alarm after the combustion gas of combustible gas probe detecting leakage and warning information is transferred to sound and light controlled delay switch action, thus make vent fan work forced exhaust, be vented also continuous in the continuous situation of warning, thereby eliminate complete hidden danger, the manual switch simultaneously arranged can be used for strengthening air circulation at ordinary times, also can be urgently needed when automatic switch is malfunctioning, the gas exhaust duct of more than 5 meters arranged forms nature draft, decrease the chance that gas leakage is piled up, effectively prevent the generation of explosion accident further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-explosion fuel gas automatic alarm exhaust apparatus.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model anti-explosion fuel gas automatic alarm exhaust apparatus is described in further detail.
As shown in the figure, anti-explosion fuel gas automatic alarm exhaust apparatus of the present utility model, comprise the combustible gas probe 3 for detecting gas leakage and the exhaust fan 5 for getting rid of leakage combustion gas, combustible gas probe 3 is connected on power circuit 1, the alternating current of said power circuit access 220V50Hz, the air outlet of exhaust fan 5 connects gas exhaust duct 6; The audible-visual annunciator that can give the alarm according to the detection information of combustible gas probe is provided with in combustible gas probe 3, also comprise the sound and light controlled delay switch 4 that can receive the alerting signal that audible-visual annunciator sends, sound and light controlled delay switch 4 is connected with exhaust fan 5 and in incoming transport electricity, can be controlled the switch of exhaust fan thus by the break-make of sound and light controlled delay switch 4; Wherein, preferably the height of gas exhaust duct 6 is set to more than 5 meters, thus when nature draft can be formed without any when external force or power, decreases gas leakage and pile up.
Further, be provided with hand switch 2 before said exhaust fan 5 and the input circuit of sound and light controlled delay switch 4, that is exhaust fan 5 is directly linked in alternating current, directly can be controlled the switch of exhaust fan thus by controlled switch.
Claims (3)
1. an anti-explosion fuel gas automatic alarm exhaust apparatus, is characterized in that: comprise the combustible gas probe (3) for detecting gas leakage and the exhaust fan (5) for getting rid of leakage combustion gas, and the air outlet of described exhaust fan (5) connects gas exhaust duct (6); The audible-visual annunciator that can give the alarm according to the detection information of combustible gas probe is provided with in described combustible gas probe (3), also comprise the sound and light controlled delay switch (4) that can receive the alerting signal that audible-visual annunciator sends, described sound and light controlled delay switch (4) is connected with exhaust fan (5).
2. according to anti-explosion fuel gas automatic alarm exhaust apparatus according to claim 1, it is characterized in that: the height of described gas exhaust duct (6) is more than 5 meters.
3. according to anti-explosion fuel gas automatic alarm exhaust apparatus according to claim 1, it is characterized in that: described exhaust fan (5) is provided with hand switch (2).
