Abstract
The utility model relates to a language alarming safety helmet at the moment of a person nearing electricity, which is used for the wearing of a high voltage electric worker in working. The utility model is made of integrated electronic components based on the principle of electric field induction. The utility model is composed of a safety helmet and a language alarm 2. The language alarm is fixed on the top of the safety helmet. The language alarm is composed of aninduction coil, an electric field testing circuit, a language circuit, a self-testing circuit, an amplifying circuit, and a power supply. When workers worn the utility model enter an electrified area in mistake and reach a definite distance, the utility model can send out the alarm of 'Danger, keep away please. ' automatically to avoid the casualty accident caused by the electric shock of the body of a person.
Description
The utility model relates to a kind of near electric language alarm safety helmet of wearing during for high-voltage electrical apparatus staff operation.
At present still do not have desirable electrician and protect facility; general examination and repair for high-pressure circuit is to carry out after having a power failure; at the circuit complex area; the operation of mistakenly entering into charged district will cause life danger; Chinese patent 2125932U discloses " the formula electrician cap of speaking " its electonic speech system multiple functions such as recording self check, warning, loop playback, de-noising and storage; its complex structure, the cost height is difficult for popularizing.
The purpose of this utility model is to overcome the weak point in the background technology and provides a kind of simple in structure, in light weight, and static power consumption is low, the languages type safety helmet capable of giving alarm near electricity that cost is low.
The purpose of this utility model is achieved in that it is made up of safety helmet and language alarm two parts, language alarm is curved, place the top of safety helmet, language alarm is made up of inductive coil, electric field sensing circuits, language circuit, self-checking circuit, amplifying circuit, power supply, inductive coil connects the electric field sensing circuits input end, electric field sensing circuits output termination language circuit 3 pin, language circuit 4 pin meet the BG of amplifying circuit
3Base stage, self-checking circuit, electric field sensing circuits, language circuit are connected with power supply.
The purpose of this utility model can also realize by following measure: electric field sensing circuits is by resistance R
1, R
2, triode BG
1, BG
2Form BG
1Base stage and variable resistor R

2Base stage, BG
2Collector connects 3 pin of language circuit, and emitter connects power cathode; Resistance R of series connection between 5 pin of language circuit and 6 pin
3, also resistance in series R not
1Inductive coil places the inner ring of safe cap.
Its principle of work is: energized does not have electric field signal as if in the inductive coil, then BG
1Be low resistive state, BG
2End, the language IC circuit can not trigger, and be the state of alert this moment.
BG when having electric field signal to flow through in the inductive coil and reaching certain intensity
1Be high-impedance state, BG
2Trigger IC after the conducting
3Pin, by 4 pin output language signals through BG
3Amplify the back and promote the warning that loudspeaker sends " please don't be close, electricity danger is arranged ".R
1Be used for high speed sensitivity, it is decided by the distance of alarming in short range of electric power, R
2Be BG
2Inclined to one side value resistance, R
3Be oscillation resistance, the height of its decision language tone.
It is little, in light weight that the utility model has volume compared to existing technology; The static power consumption is low, only about 5 μ A; Circuit is simple, and low cost and other advantages is for the workman of examination and repair for high-pressure electric wire provides safety assurance.

3, amplifying circuit is by a triode BG
3Form with loudspeaker, language circuit 4 pin meet BG
3Base stage, self-checking circuit AN, electric field sensing circuits, language circuit and connect power cathode.Its electric field sensing circuits is by resistance R
1, R
2, triode BG
1, BG
2Form BG
1Base stage and variable resistor R
1, inductive coil G connects, collector meets BG
2Ground level, BG
