Abstract
The utility model provides an electric shock preventive helmet with a voice alarm function, which can send warning voice such as 'Danger, electric shock risk' when being close to charged objects or live lines. The helmet comprises a helmet body, and is characterized in that an induction electrode, an electronic trigger circuit, a voice alarm circuit, a loudspeaker, a power amplifier circuit, a power switch, a rechargeable battery and a charging socket are mounted in the helmet body. When a person wearing the helmet is close to the live circuits or devices, charged field intensity is induced by the induction electrode, the electronic trigger circuit is triggered after the field intensity is input to the electronic trigger circuit, and then a voice module can send warning sound such as 'danger, electric shock risk' to warn operators at any places and any time, thereby preventing accidental electric shock.
Description
Technical field
The utility model relates to safety cap, relates in particular to a kind of safety cap of energy audio alert.
Background technology
At present, known safety cap is mainly used in waterproof or protection etc.Its protective effect is very limited.Especially when operating personnel are in the operation of peripheral band electrical environment, do not have timely prompting operating personnel and prevent the purpose of its accidental shock.Particularly operating personnel are when pole-climbing or mine underground work, and various electrical wirings are crisscross, and operating personnel are on tenterhooks during the repairing circuit, and electric shock accidents very easily takes place.And safety cap that operating personnel wore can not send alarm signal and reminded operating personnel to take care this moment, to prevent accidental shock.
Summary of the invention
In order to overcome the deficiency of existing safety cap, the utility model provides a kind of safety cap that can send the caution voice of " electricity is arranged, and Danger! Keep Away " and so near charged object or circuit the time.So that remind operating personnel to take care timely, reach the purpose that prevents accidental shock.
The technical solution adopted in the utility model is: it comprises safety cap cap body, it is characterized in that, induction electrode, electronics circuits for triggering, voice alarm circuit, loudspeaker, power amplifier, power switch, rechargeable battery and charging socket are installed in safety cap cap body; Their annexation is: induction electrode connects electronics circuits for triggering input, and electronics circuits for triggering output connects voice alarm circuit, power amplifier and loudspeaker successively.Rechargeable battery has been connected respectively to the operating voltage end of foregoing circuit.
Its operation principle is: in the time of near operating personnel are in alive circuit or electrical equipment, induction electrode is sensed charged field intensity, and this field intensity is input to the electronics circuits for triggering, and the electronics circuits for triggering can be triggered, and voice module can the output alarm voice.Alarm voice is exported from loudspeaker after the power amplifier audio power amplifies.Reached and made the clear loud and clear effect of alarm voice.Rechargeable battery provides suitable operating voltage for above circuit.Rechargeable battery external charge socket can be its charging by external suitable charger.
Good effect of the present utility model is: on circuit or electrical equipment have forceful electric power, light current to exist, safety cap will send " having electricity dangerous; please don't be close " near about tens centimetres of these lines the time, caution sound, remind operating personnel to take care whenever and wherever possible, reach the purpose that prevents accidental shock.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Among the figure: A--induction electrode, B--electronics circuits for triggering, C--voice alarm circuit, D--power amplifier.
The specific embodiment
As shown in Figure 1, induction electrode A, electronics circuits for triggering B, voice alarm circuit C and power amplifier D at first are installed in the safety cap body.Induced voltage electronics circuits for triggering B is made up of 555 integrated circuits, resistance and electric capacity etc.Voice alarm circuit C is made up of BA08 type voice module, resistance and electric capacity etc.Power amplifier D is made up of LM386 power amplifier chip, resistance and electric capacity etc.Loudspeaker is selected the little high-decibel loudspeaker of volume for use.Induction electrode A area is big more, and distance of reaction is big more, sensitivity is high more.Be integrated with the alarm voice of " electricity is arranged, and Danger! Keep Away " in the BA08 type voice module among the voice alarm circuit C.Power amplifier D has selected for use the LM386 audio power to amplify chip.Power switch K is connected in total current supply circuit.All the other elements are selected, are connected enforcement for use by circuit theory diagrams and get final product.Foregoing circuit is common circuit, is not described in detail at this.
Claims (2)
1. protection against electric shock audio alert safety cap, it comprises safety cap cap body, it is characterized in that, induction electrode, electronics circuits for triggering, voice alarm circuit, loudspeaker, power amplifier, power switch, rechargeable battery and charging socket are installed in safety cap cap body; Their annexation is: induction electrode connects electronics circuits for triggering input, and electronics circuits for triggering output connects voice alarm circuit, power amplifier and loudspeaker successively, and rechargeable battery has been connected respectively to the operating voltage end of foregoing circuit.
2. protection against electric shock audio alert safety cap as claimed in claim 1 is characterized in that voice alarm circuit is made up of BA08 type voice module, resistance and electric capacity.
