Abstract
The utility model provides a combustible gas safety alarm which is suitable for occasions of households, industrial and mining establishments, and other any occasions where combustible gas (the specific gravity of the combustible gas is larger than the specific gravity of air) can leak. The combustible gas safety alarm comprises a sealed float box, a mercury pipe lever which is filled with mercury, a support shaft, a support seat, an announciator, a mercury switch, etc., wherein, the mercury pipe lever is arranged on the support shaft, and both ends of the mercury pipe lever are respectively provided with the float box and the announciator. The mercury pipe lever is also provided with a leveller and a mercury switch which is connected with the announciator. The support shaft is arranged on the support seat arranged on a base. The utility model has the advantages of simple structure, high sensitivity, reliable work and convenient allocation.
Description
The utility model provides a kind of inflammable gas safety alarm, and it is applicable to family, industrial and mining enterprises and other any places that the inflammable gas leakage might take place.The inflammable gas of present specification indication is the inflammable gas of proportion greater than air, as the inflammable gas of forming by methane, propane and other stable hydrocarbon, and example: liquefied gas, natural gas, biogas, Device in Gas etc.
Use liquefied gas in the family, might produce leakage, methane gas is arranged in the mine.When reaching certain content (ratio) in air, these inflammable gases just might blast.The purpose of this utility model is exactly: just report to the police when inflammable gas reaches certain content, thereby people just take measures to avoid blast after hearing warning.The utility model utilizes the law of buoyancy and lever law to make the inflammable gas warning device.
The technical solution of the utility model is such: the inflammable gas alarm contains signalling means (8), the buoyancy tank of enclosure-type (1), the mercury tube lever (2) of mercury is housed, fulcrum (3), bearing (4), pointer (6), direction board (5), mercury cut-off (7), base (9) etc., connection assembly relation between them is: mercury tube lever (2) is contained on the fulcrum (3), its two ends are mounted with buoyancy tank (1) and signalling means (8) respectively, signalling means (8) connects with lead with mercury cut-off (7), mercury cut-off (7) is placed on the mercury tube lever (2), mercury tube lever (2) also is equipped with leveller (12) and pointer (6), fulcrum (3) is contained on the bearing (4), and bearing (4) is contained on the base (9).The two ends of mercury tube lever (2) also is equipped with regulating block (10), (11).Direction board (5) is contained on the bearing (4).
Advantage of the present utility model is: simple in structure, highly sensitive, and reliable operation, it is convenient to settle.
Fig. 1 is an inflammable gas safety alarm structural drawing.
In conjunction with the accompanying drawings the utility model is further described.The inflammable gas safety alarm is by signalling means (8), enclosure-type buoyancy tank (1), the mercury tube lever (2) of mercury is housed, fulcrum (3), bearing (4), pointer (6), direction board (5), mercury cut-off (7), base (9), leveller (12), regulating block (10), (11) etc. parts are formed, connection assembly relation between them is: mercury tube lever (2) is contained on the fulcrum (3), its two ends are mounted with buoyancy tank (1) and signalling means (8) respectively, signalling means (8) is the HYPER-8 type, connect with lead with mercury cut-off (7), mercury cut-off (7) is placed on the mercury tube lever (2), mercury tube lever (2) also is equipped with leveller (12) and pointer (6), fulcrum (3) is contained on the bearing (4), and bearing (4) is contained on the base (9).The two ends of mercury tube lever (2) also is equipped with regulating block (10), (11), and direction board (5) is contained on the bearing (4).
The utility model has used lever law and Archimedes's the law of buoyancy.Using method is as follows: this alarm is placed on the smooth plane, is not having under the situation of inflammable gas, adjust leveller (12) and regulating block (10), (11), pointer (6) is parked on the middle zero-bit of direction board (6).The suffered buoyancy of buoyancy tank (1) this moment is assumed to be x.When being mixed with proportion greater than the inflammable gas of air in the air, the suffered buoyancy of buoyancy tank (1) is assumed to be y.Clearly, y is greater than x.The y value changes with the aerial ratio of inflammable gas, ratio is big more, the y value is big more, because y is greater than x, buoyancy tank (1) upwards lifts, and mercury tube lever (2) tilts to signalling means (8) end, when tilting to a certain degree, mercury in the mercury tube lever (2) flows into mercury cut-off (7), connects the circuit of mercury cut-off (7) and signalling means (8), and signalling means (8) sends persistent signal and reports to the police.Alerting signal can be sound or the two combination of light.The utility model is an acousto-optic generator.The size of buoyancy tank (1) volume can design with different purposes according to different inflammable gases, it with the proportion of inflammable gas with when reporting to the police in the air minimum content of inflammable gas corresponding.Embodiment of the present utility model, that home-use is 0.005m
3, that mine is used is 0.05m
3When harmful gas content reaches 7% in the air, just report to the police.The utility model alarm only is applicable to the inflammable gas of proportion greater than air.
Claims (2)
1, the inflammable gas safety alarm, contain signalling means, of the present utility model being characterised in that: it also contains the buoyancy tank (1) of enclosure-type, the mercury tube lever (2) of mercury is housed, fulcrum (3), bearing (4), pointer (6), mercury cut-off (7), connection assembly relation between them is: mercury tube lever (2) is contained on the bolster (3), its two ends are mounted with buoyancy tank (1) and signalling means (8) respectively, signalling means (8) connects with lead with mercury cut-off (7), mercury cut-off (7) is placed on the mercury tube lever (2), also be mounted with leveller (12) and pointer (6) on the mercury tube lever (2), fulcrum (3) is contained on the bearing (4), and bearing (4) is contained on the base (9).
2, alarm according to claim 1 is characterized in that the two ends of mercury tube lever (2) also is equipped with regulating block (10), (11).
