Description
One, technical field
This demonstration device relates to field of electric control, the demonstration device of especially a kind of oil depot, refuelling station's No Mobile Phones principle.
Two, background technology
Can use mobile phone in occasions such as oil depot, refuelling stations, have necessarily dispute.
Available theory is thought, if the gasoline leakage rate of an oil depot, refuelling station can reach explosive range, then close the door for a long time and rectified in oil depot, refuelling station; Two, the evidence of U.S. science popularization program Discovery is arranged, and in the refuelling station's explosion chamber in being modeled to reality, mobile phone has rung and had not also set off an explosion in tens minutes; Three, at home and abroad, the refuelling station's explosion accident that is proved because using mobile phone to cause exists hardly.
Forbidding says and thinks that gasoline is volatile combustible that oil tank and pipeline thereof gasoline may occur leak; When the refuelling station added gasoline by oil gun to the fuel tank notes, oily vapour just outwards flew away, thereby oil depot, refuelling station's oil vapour density are increased suddenly.Mobile phone is widely used radio communication instrument, and the electromagnetic wave signal that it is launched when running into metallic conductor, electromagnetic induction occurs, and produces induced voltage, when induced voltage runs up to a certain degree, point discharge can occur, and produces spark.Therefore, use the explosion caused possibility of mobile phone very large in occasions such as oil depot, refuelling stations.
Through preliminary inquiry, not yet find works or the document of demonstration " oil depot, refuelling station's No Mobile Phones principle ".
Three, summary of the invention
Invent the purpose of this demonstration device, provide the demonstration device of a kind of oil depot, refuelling station's No Mobile Phones principle.
The demonstration device of oil depot, refuelling station's No Mobile Phones principle, it is by direct supply, the incoming call prompting circuit, control circuit, high-pressure generating circuit, explosive release forms.It is characterized in that direct supply accesses respectively incoming call prompting circuit, high-pressure generating circuit, the incoming call prompting circuit output end is connected with the control circuit input end, the control circuit output terminal is connected with the high-pressure generating circuit power input, the high-tension electricity that high-pressure generating circuit produces is incorporated in the explosive release by electrode.Explosive release is the device that the effluve spark is ignited the gaseous state combustible, high-field electrode links to each other with the high-pressure generating circuit output terminal, pass flat board after, become most advanced and sophisticated relatively adjacent states, the wide mouth cup that presets the gaseous state combustible covers on the high-field electrode, and wide mouth cup is fastened on flat board with thin and soft wire.
This demonstration device is when standby, in case mobile phone is dialed or is received in demonstration device actual induction scope, the incoming call prompting circuit is namely sensed the signal of enabling of mobile phone, its output terminal output high level, make the control circuit conducting, high-pressure generating circuit gets electric, produces high pressure, and then the generation point discharge, ignite the gaseous state combustible that is preset in the wide mouth cup.Thereby simulated oil depot, refuelling station and used the principle that mobile phone may be explosion caused---when electromagnetic wave signal that mobile phone launches runs into metallic conductor, electromagnetic induction occurs, produce induced voltage, when induced voltage runs up to a certain degree, point discharge occurs, produce spark, cause oily vapour blast.
The beneficial effect of this demonstration device is:
1. after this demonstration device is sensed mobile phone signal, namely produce high-voltage spark, and then ignite the gaseous state combustible.By demonstration, further warn people at the place No Mobile Phones of the oily steam packing collection such as oil depot, refuelling station, in order to avoid accidents caused.
2. highly versatile.The gaseous state combustible that is detonated can be inflammable gas, volatile flammable liquid and fly away flammable solid; Be suitable for the 1. demonstration of oil depot, refuelling station's No Mobile Phones principle; 2. the teaching of junior middle school chemistry " burning and blast " content; 3. the occasion such as entertainment is used.
3. principle of device science, rational in infrastructure can be reused quickly and easily.

Five, embodiment
Embodiment 1
Below in conjunction with accompanying drawing 2, this demonstration device is done further narration.
The demonstration device of oil depot, refuelling station's No Mobile Phones principle is formed by direct supply 1, incoming call prompting circuit, control circuit, high-pressure generating circuit, explosive release.
Direct supply 1 is 4-8V ac-dc conversion power supply.
Explosive release is the device that the effluve spark is ignited the gaseous state combustible, high-field electrode links to each other with the high-pressure generating circuit output terminal, pass flat board after, become most advanced and sophisticated relatively adjacent states, the wide mouth cup that presets the gaseous state combustible covers on the high-field electrode, and wide mouth cup is fastened on flat board with thin and soft wire.Wide mouth cup is the transparent toughness material.
The connected mode of this demonstration device is as follows:
1. civil power access ac-dc conversion power circuit produces direct current.
2. direct current accesses respectively incoming call prompting circuit, high-pressure generating circuit.
3. the incoming call prompting circuit output end is connected with the control circuit input end.
4. the control circuit output terminal is connected with the high-pressure generating circuit power input.
5. the high-tension electricity that produces of high-pressure generating circuit is incorporated in the explosive release by two electrodes.
The using method of this demonstration device:
1. demonstration device plugged.
2. after spraying into an amount of gasoline mist to wide mouth cup, immediately wide mouth cup is covered on the high-field electrode.
3. without hindrance under state between demonstration device and mobile phone, centered by demonstration device, in 1.5 meters scopes of radius, enable mobile phone and (1. dial or receipt of call; 2. send or receive note).
At this moment, can see that the gasoline that is preset in the wide mouth cup is blasted at once.
