Description

Diffuse transmission type voice chemical industry safety warning device

The utility model relates to commercial production and the other field diffuse transmission type voice chemical industry safety warning device that occasion points out the field staff and report to the police that easily has an accident.

Some studies show that, in modern commercial production and work, be easy to occur occasion dangerous and that have an accident for some, use the double action of acousto-optic to the sense of hearing and vision generation, may or imminent peril circulate a notice of clearly to the field staff particularly necessary, for reducing and avoiding the generation of peril can play active and effective effect.But, still do not have at present the safety warning device of the strong good warning effect of a kind of applicability in the industrial circle.On the other hand, the rapid alert sound that on vehicles such as fire-fighting, public security, rescue, is provided with and the audible-visual annunciator of monochromatic flash of light, the simple voice prompting device that use the level crossing, the voice suggestion board that power department uses, and with the utility model immediate with alert sound do the poster sound accompaniment warning device (patent No. 91230104.X) though etc. tool have certain effect, but there is following shortcoming: one, the alarm song of specific connotation only is applicable to specific occasions; Its two, rapid chimes of doom is dull sharp-pointed, and people are had stronger stimulation and certain interference; Its three, usually the direct-injection type playback modes directive property that adopts is very strong, sound field is inhomogeneous on every side, influence caution effect; Its four, monochromatic flicker ruddiness obviously reduces in its warning of steam smog occasion; Its five, simple voice suggestion warning is not strong, and alert sound is done the two phase mutual interference of sound accompaniment of poster, warns indeterminately, therefore, is not suitable as the widely used effective and safe attention device of industrial circle.

The purpose of this utility model is to provide and is suitable for the widely used diffuse transmission type voice chemical industry safety warning device with strong audiovisual caution effect of industrial circle, so that efficiently and effectively improves the security of production and work.

The purpose of this utility model is realized by following scheme: have a casing 10, be installed on loudspeaker 6 in the casing, playback opening part at casing is installed on sound reflection lid 9, cover at casing side or sound reflection flash caution lamp 7 is installed, loudspeaker is connected with the speech generating circuit that can send alert sound poster signal chronologically.

In the such scheme, speech generating circuit includes sound-compound-circuit 3 and the coupled power amplification circuit that has regulator 45, flash caution lamp 7 can be made of two or more lampions, wherein there is one to be amber light, to produce the secondary color flash of light, strengthen the excitement of vision in the smog occasion, and yellowly have the connotation of " warning " and " attention " in safety color, warning is stronger.

Press in the such scheme, when the utility model enters alert status, open the flash caution lamp on the one hand and launch the secondary color flash of light towards periphery, from visually giving the field staff with the caution effect, loudspeaker sends rapid sound such as alert sound or bell earlier with certain time sequence simultaneously, make the field staff produce of short duration alerting stimulus and attention, then express the content and the character of caution with simple and clear poster, reminds people is taked corresponding action, the above-mentioned sound language of repeat playing again in a moment pauses, form the circulation in sounding cycle, further strengthen warning function.Therefore it is ear-piercing and connotation not clear and confused weak point appears in alert sound poster simultaneously to have avoided flat, the permanent alert sound of simple voice suggestion, overcomes the shortcoming in the prior art, has reached alert and is not tired of, shows and not unconcerned clearly caution effect.The scattering sound reproduction structure that the utility model adopts casing to combine with the sound reflection lid, make sound wave in casing, reverberate reflection phase shift paraphase, tonequality improves, being dispersion shape after sound wave fills the air in case propagates from the interval of reflection lid and casing towards periphery, around attention device, constitute uniform sound field, make the interior personnel of caution scope can both hear to clear and definite the prompting of alert sound poster, cause enough vigilance inwardly, avoid and prevent the generation of accident, reach the purpose of safety.In addition, because all even tone quality improving of sound field, and the characteristics with adjustable power, the utility model also can reduce the interference to surrounding environment to greatest extent.
