The utility model discloses a voice structure of a portable mining intrinsically safe type annunciator. The voice structure of the portable mining intrinsically safe type annunciator comprises a cavity body, wherein the outer side of the cavity body is provided with an intrinsically safe button switch and an aviation plug for charging, one side of the cavity body is provided with a rear cover, the other side of the cavity body is provided with a voice horn and a red organic glass transparency window, the top end of the cavity body is provided with a lithium ion battery intrinsically safe power supply module, the bottom of the cavity body is provided with a caution voice chip, an amplification circuit board is installed between the caution voice chip and the lithium ion battery intrinsically safe power supply module, and the top of the cavity body is provided with a handle. The voice structure of the portable mining intrinsically safe type annunciator is reasonable in design, simple in structure and convenient to install. The bottom of the cavity body is provided with an intrinsically safe type signal lamp shell, the intrinsically safe type signal lamp shell is provided with a high brightness light emitting diode (LED) lamp panel, the high brightness LED lamp panel is provided with a high brightness LED lamp bulb, thus the voice structure of the portable mining intrinsically safe type annunciator is simple to maintain and safe and reliable in function, and plays an effectively safeguard and caution role.
Description
Technical field:
The utility model relates to a kind of mining signal device, is specifically related to a kind of phonetic structure of Portable mining essential safe type signalling means.
Background technology:
The signalling means that use for a long time in the transport place under the coal mine mostly is greatly the mining general signalling means, and stream time is short, reliability is relatively poor, sound is little, can not use in the environment of damp is arranged, and can not adapt to the needs that coal mine downhole safety is produced; Need to carry out technological innovation and transformation.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of phonetic structure of Portable mining essential safe type signalling means is provided, so just solved the mining general signalling means, stream time is short, reliability is relatively poor, can not in the environment of damp is arranged, use, can not adapt to the problem of the needs of coal mine downhole safety production.
The utility model solution is as follows:
A kind of phonetic structure of Portable mining essential safe type signalling means, include a cavity, the outside of described cavity is provided with intrinsic safety press button and charging aviation plug, one side of described cavity is provided with bonnet, the opposite side of described cavity is provided with speech horn and red plexiglass transparency window, the top is provided with lithium-ions battery intrinsically safe power supply assembly in the described cavity, the bottom is provided with the phonetic warning chip in the described cavity, be provided with magnification circuit plate between described phonetic warning chip and the lithium-ions battery intrinsically safe power supply assembly, described cavity top is provided with handle.
Also be provided with the red plexiglass transparency window on the described bonnet.
Its operating principle is: the outside of cavity is provided with intrinsic safety press button and charging aviation plug; one side of cavity is provided with bonnet; the opposite side of cavity is provided with speech horn and red plexiglass transparency window; the top is provided with lithium-ions battery intrinsically safe power supply assembly in the cavity; the bottom is provided with the phonetic warning chip in the cavity; be provided with magnification circuit plate between phonetic warning chip and the lithium-ions battery intrinsically safe power supply assembly; the cavity top is provided with handle; the signalling means working power voltage is DC7.4V; lithium-ions battery intrinsically safe power supply assembly adopts the dual guard shield; has overcurrent; overvoltage; short circuit; overcharge and over; output DC7.4V; 1.6A intrinsic safety electric source is to speech chip DT588D able to programme; TDA2003 audio power amplifier circuit and two groups of high-brightness LED lamp assemblies provide intrinsic safety electric source; sound circuit able to programme can generate and store several audio alert signals; and select one of them audio alert signal to export; also be provided with the red plexiglass transparency window on the bonnet; like this will be so that product maintenance be simple; stream time is long; performance safety is reliable, plays effective safeguard protection warning function.
The utility model is reasonable in design; simple in structure; easy for installation; the bottom of cavity is provided with intrinsic safety signal lamp shell; be provided with the high-brightness LED lamp plate in the intrinsic safety signal lamp shell, the high-brightness LED lamp plate is provided with the high-brightness LED bulb, like this will be so that product maintenance is simple; performance safety is reliable, plays effective safeguard protection warning function.
