Abstract
The utility model relates to a novel mine lamp cap which comprises a singlechip circuit powered by a DC (direct current) power supply and arranged in a cap main body, a gas sampling circuit, an alarm circuit, wherein the gas sampling circuit and the voice alarm circuit are respectively connected with the singlechip circuit; the gas sampling circuit detects gas density which is transmitted to the singlechip circuit; a critical value of the safety gas density is internally set to the singlechip circuit; the singlechip circuit compares the detected density with the internally set critical value; when the detected density is larger than or equal to the critical value, the singlechip circuit sends out a logic alarm signal to the alarm circuit; and the alarm circuit receives the alarm signal and then gives an alarm. The utility model has the advantages of simple structure, easy manufacture and low cost, and can give an alarm in time, thereby providing effective life safety guarantee for workers.
Description
Technical field
The utility model relates to down-hole mining and uses miner light cap, relates in particular to a kind of novel miner's lamp cap that can report to the police when gas density exceeds standard.
Background technology
Miner light cap is the instrument that underground work must be equipped with as a kind of portable equipment, protects workman's head to exempt from injury first, second uses as illumination.In recent years, the gas explosion of mine happens occasionally, and seriously influences people's life security.Yet existing miner light cap does not also have the function of gas alarming.
The utility model content
The utility model is at the above-mentioned defective of prior art, and a kind of novel miner's lamp cap that can exceed standard and report to the police gas density is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of novel miner's lamp cap, it comprises the cap main body, be arranged at the illuminating lamp holder of body front end, and place dc source in the main body, illuminating lamp holder is connected with dc source with lead, also comprise the single chip circuit that is arranged in the main body by DC power supply, the gas sample circuit, warning circuit, the gas sample circuit is connected with single chip circuit respectively with the language alarm circuit, described gas sample circuit detects gas density, and this concentration value is sent to single chip circuit, the built-in safety gas concentration of described single chip circuit critical value, single chip circuit is with detected concentration value and built-in critical value comparison, when detected concentration value during more than or equal to critical value, single chip circuit sends the logic alarm signal to warning circuit, and warning circuit is carried out warning after receiving alarm signal.
Preferably, described warning circuit comprises audio alert unit and LED alarm unit, and described warning circuit is carried out when reporting to the police, and the audio alert unit sends " gas exceeding limit, danger! Withdraw soon! " alarm voice, LED alarm unit control LED flicker is lighted, the LED periphery encapsulates with red transparent material.
As can be seen from the above technical solutions, the utility model will increase gas sample circuit and warning circuit in the miner light cap, when detected gas density greater than or single chip circuit in margin of safety the time, the control warning circuit is carried out sound and light alarm, has increased the gas alarming function of miner light cap.When the gas density in the mine exceeded standard, the utility model can in time be reported to the police, and provided effective safety guarantee to the workpeople.In sum, the utility model is simple in structure, makes easily, and cost is low, and dark tool practicality.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram;
Fig. 2 is the utility model shape assumption diagram.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
Referring to shown in Figure 1, the control circuit that the utility model is arranged in the miner light cap comprises: dc source 1, LED lighting circuit 2, single chip circuit 3, gas sample circuit 4, warning circuit 5, dc source is connected with other four circuit respectively provides dc source, and the LED lighting circuit mainly comprises lead and the interior bulb of lamp holder that is connected between dc source and the miner light cap front end lamp holder; The gas sample circuit is connected with single chip circuit, detects the concentration of gas in the air, and this concentration value is sent to single chip circuit; Single chip circuit also is connected with warning circuit, the margin of safety of the built-in gas density of single chip circuit, and constantly with the gas concentration and margin of safety comparison that detect, when detect concentration value during more than or equal to margin of safety, send the logic alarm signal to warning circuit; Warning circuit receives this quotation signal and carries out warning.
Because the explosion ratio of gas is 5%～16%, and gas density was above 16% o'clock, oxygen content is not enough to breathe for the workman in the air, therefore, the margin of safety that the utility model is set in single-chip microcomputer is 4%, guaranteeing safety of workers, and this critical value can be finely tuned under special circumstances.
As preferred implementation of the present utility model, described warning circuit 5 comprises audio alert unit and LED alarm unit, and described warning circuit is carried out when reporting to the police, and the audio alert unit sends " gas exceeding limit, danger! Withdraw soon! " similar audio alert, simultaneously, LED alarm unit control LED flicker is lighted, and the material of packaged LED is red transparent material on the miner light cap.
Again referring to shown in Figure 2, the novel miner's lamp cap comprises cap main body 44, be arranged at the illuminating lamp holder 11 of body front end and place dc source (not shown) in the main body 44, and illuminating lamp holder 11 is connected with dc source with lead 22.Cap main body 44 tops are provided with red LED alarm lamp 33.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
Claims (2)
1. novel miner's lamp cap, it comprises the cap main body, is arranged at the illuminating lamp holder of body front end and places the interior dc source of main body, illuminating lamp holder is connected with dc source with lead, it is characterized in that: comprise also being arranged in the main body that the gas sample circuit is connected with single chip circuit respectively with warning circuit by single chip circuit, gas sample circuit, the warning circuit of DC power supply.
