Abstract
The utility model discloses a coal gas alarm device, it constitutes as follows: casing (1), coal gas sensor (2), alarm (3), controller (4), hair -dryer (5), suction fan (6), motor (7), door and window push rod (8) and cut out cock (10), coal gas sensor (2) link to each other with controller (4) input, and alarm (3), hair -dryer (5), motor (7) link to each other with controller (4) output, controller (4) are the AT89S52 singlechip, realize timing control with the singlechip, and the circuit is simple, low price, good reliability, coal gas alarm device simple structure, intelligence effectual avoid because of coal gas misuse for the problem that the masses brought life and property safety, economic value and social value have.
Description
Technical field
The utility model relates to structural design and the applied technical field of warning device, specifically provides a kind of gas alarm device.
Background technology
At present, coal gas becomes essential instrument in people's daily life, but, because coal gas improper use causes the case of the person and property of common occurrence to the masses.
People urgently wish to obtain the excellent gas alarm device of a kind of technique effect.
Utility model content
Order of the present utility model is to provide a kind of gas alarm device.
Described gas alarm device is constructed as follows: housing 1, gas sensor 2, alarm 3, controller 4, hair-dryer 5, suction fan 6, motor 7, door and window push rod 8 and roof-cut resistence 10, described gas sensor 2 is connected with controller 4 input end, alarm 3, hair-dryer 5, motor 7 is connected with controller 4 output terminal with roof-cut resistence 10, described roof-cut resistence 10 is connected with gas fitting, after gas sensor 2 detects unusual condition, gas fitting is closed by controller 4 and roof-cut resistence 10, get rid of disaster, controller 4 is AT89S52 single-chip microcomputer, use chip microcontroller timing controlled, circuit is simple, low price, good reliability, motor 7 is connected with door and window push rod 8, door and window push rod 8 is connected with door and window, door and window push rod 8 is the Hollow circular beam of diameter 5cm, ensure that door and window can effectively be pushed open by door and window push rod on the one hand, on the other hand, weight reduction, gas sensor 2, alarm 3, controller 4, suction fan 6 and motor 7 are positioned at housing 1, the upper end of described housing 1 is provided with trumpet-shaped ventilation port 9, suction fan 6 is positioned at ventilation port 9 place, hair-dryer 5 is positioned at the lower end of housing 1.Ventilation port 9 is made horn-like, increase the contact area with air, because coal gas is heavier relative to air, ventilation port 9 is placed in housing 1 upper end and adopts suction fan 6 to carry out air draught, be conducive to when gas leak occurs, leakage coal gas detected more timely sooner, security is higher, after ventilation port 9 suction gas, gas sensor 2 detects the concentration of wherein coal gas, when exceeding the concentration preset, controller 4 controls alarm 3 and gives the alarm, simultaneously, controller 4 starter motor 7 works, motor 7 promotes door and window push rod 8 by opening of doors and windows, thus play the object of dilution gas concentration.
Gas alarm device structure described in the present embodiment is simple, and intelligence effectively avoids the problem because coal gas improper use brings life and property safety to the masses, has economic value and social value.
Accompanying drawing explanation
Fig. 1 is gas alarm device structural representation.
