Abstract
A gas alarm safety helmet relates to a safety warner of coal mine detection gas concentration, which consists of a charger (1) with a handle (3) on the safety helmet (8), a control box and a control circuit. The charger (1) on the control box (9) is provided with a telescopic charging plug (4). The output end of the charger is connected with a lithium polymer battery (2). The output end of the battery is 6V and is connected with the control circuit. When the gas concentration is low and does not reach a certain value, the conductivity between A and B of an air-sensitive component (6) is very small. Because the output voltage of the slide contact of a potential device (12) is less than 0.7V, the fourth pin of an integrated block (11) is forcibly reset, an oscillator does not work and an alarm horn does not produce sound. When the gas concentration of surrounding air reaches a certain value, the conductivity between A and B of the air-sensitive component (6) is increased quickly, the third pin of the integrated block (11) becomes high frequency, an oscillating circuit vibrates, the horn sends out alarm sound, emergency measures are taken at once and life and property loss is avoided.
Description
Technical field
The utility model relates to a kind of colliery and detects the gas density safety alarm.
Background technology
Present known coal mine gas from explosion is very big safety problem, is mostly to cause great misfortune by reporting to the police untimely, causes life and property loss.
Summary of the invention
In order in time to report to the police, the utility model provides a kind of gas alarming safety cap, workman's work that puts on a safety helmet, and whether the concentration that just can detect gas whenever and wherever possible exceeds standard, and reaches the purpose of timely warning.
Its technical scheme of the technical problems to be solved in the utility model is: by the charger of band handle on the safety cap with control box is housed and control circuit is formed.Its structure is: the inserted sheet that cooperates with control box is arranged on behind the safety cap, the control box inner bottom surface is equipped with the collapsible charging plug of band handle, the output of charger is connected with lithium polymer battery, it above the battery control circuit, the output of battery is that 6V is connected with control circuit, gas sensor is contained in the stainless steel guard of control box, gas density that potentiometer is adjustable height, when gas density low, when not reaching certain value, gas sensor A, conductance is very little between the B, because the output voltage of potentiometer sliding contact is less than 0.7V, 4 pin of integrated package are forced to reset, oscillator is in off position, alarm sounding not, when the gas density in the surrounding air reaches certain value, gas sensor A, conductance between the B increases sharply, 3 pin of integrated package become high electricity frequently, the oscillating circuit starting of oscillation, just send chimes of doom, emergency disposal at once.
The beneficial effects of the utility model are: the miner puts on the utility model gas alarming safety cap in underground work, can both detect the concentration of gas or other pernicious gas whenever and wherever possible, just in time report to the police in case exceed standard, dispose immediately, avoid heavy casualties and property loss.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a gas alarming safety cap schematic diagram.
Fig. 2 is gas alarming safety cap power supply reason figure.
In Fig. 1,2: 1, charger, 2, lithium polymer battery, 3, handle, 4, collapsible charging plug, 5, the control box end face, 6, gas sensor, 7, the stainless steel guard, 8, safety cap, 9, control box, 10, inserted sheet, 11, integrated package, 12, potentiometer.
The specific embodiment:
The inserted sheet (10) that cooperates with control box (9) is arranged on safety cap (8) back, the control box inner bottom surface is equipped with the collapsible charging plug (4) of band handle (3), the output of charger (1) is connected with lithium polymer battery, it above the battery control circuit, the output of battery is that 6V is connected with control circuit, gas sensor (6) is installed in the stainless steel guard (7) of control box (9), potentiometer (12) can be regulated the gas density height, when gas density low, when not reaching certain value, gas sensor (6) A, conductance is very little between the B, because the output voltage of potentiometer (12) sliding contact is less than 0.7V, 4 pin of integrated package (11) are forced to reset, oscillator is not worked, alarming horn is sounding not, when the gas density in the surrounding air reaches certain value, and gas sensor (6) A, conductance between the B increases sharply, 3 pin of integrated package (11) become high electricity frequently, chimes of doom is just sent in oscillating circuit starting of oscillation, loudspeaker, should reach disposal at once.
Claims (1)
1. gas alarming safety cap, going up the charger (1) of band handle (3) and control box and control circuit by safety cap (8) forms, it is characterized in that: the inserted sheet (10) that cooperates with control box (9) is arranged on safety cap (8) back, the control box inner bottom surface is equipped with the collapsible charging plug (4) of band handle (3), the output of charger (1) is connected with lithium polymer battery (2), it above the battery control circuit, the output of battery is that 6V is connected with control circuit, gas sensor (6) is installed in the stainless steel guard (7) of control box (9), and trimmer potentiometer (12) is housed on the circuit.
