Description
Technical field:
The utility model relates to joint noise reducing apparatus, particularly relates to the special noise reducing apparatus of a kind of factory.
Background technology:
Sound is caused by object vibration, propagates in certain medium (as solid, liquid, gas) with the form of ripple.Usually the sound heard is air-borne sound.Generally, the frequency of sound wave that people's ear can be heard is 20 ~ 20,000Hz, is called audible sound; Lower than 20Hz, be called infrasonic wave; Higher than 20,000Hz, be called ultrasound wave.Hear that the height of the tone of sound depends on sound wave frequency, high frequency sound sounds sharp-pointed, and all-bottom sound is comparatively dull to the sensation of people.The size of sound is determined by the power of sound.From physical viewpoint, noise is by various different frequency, the making a noise of varying strength, irregularly combines; Musical sound is then harmonious sound.
Judge whether a sound belongs to noise, only judge it is inadequate from physics angle, subjective factor often plays conclusive effect.Such as, beautiful music concerning being just musical sound the people of music appreciating, but may be a kind of noise for the people learning, have a rest or concentrate one's energy to ponder a problem.Even if same sound, when people is in different conditions, different mood, also can produce different subjective judgements to sound, now sound may become noise or musical sound.Therefore, from physiological point, every interference people have a rest, the sound of study and work, and namely unwanted sound, is referred to as noise.When noise on human and surrounding environment cause harmful effect, just form noise pollution.
Every obstruction people normally have a rest, the sound of study and work, and the sound that people will listen are produced to the sound of interference.In this sense, the source of noise is a lot, and e.g., the sound that the voice in the automobile sound on street, quietly library, the machine sound of building ground and neighbours' televisor are excessive is all noise.Research shows, when noise is 90 decibels, in people's retina, the susceptibility of rod cell difference luminance brightness starts to decline, and identifies that the reaction time of the low light level extends; When reaching 95 decibels, pupil can expand; When reaching 115 decibels, eyes can reduce by 207 to the adaptability of luminance brightness.
In addition, the people of Long Term Contact noise, the phenomenon such as kopiopia, ophthalmodynia, blurring of vision the most easily occur and shed tears.The noise produced in transport facility driving process belongs to traffic noise.There are two features: 1. exist very extensive.Car noise is the main source of city noise; Developing rapidly of air traffic, improves the noise level of airport close region; 2. volume is all very large usually.The noise loudness of near airports is greatly between 75dB-95dB.Noise for workshop a lot of in enterprise is huge, and workers with long time as wherein causing irreversible damage to hearing in the course of time, and damages spirit.
Utility model content:
The utility model provides and a kind ofly to improve on the basis of traditional full-enclosed crash helmet; enable to protect workman's hearing healthy by increasing noise insulation equipment simultaneously; reduce the proper communication healthy negative effect brought not being affected simultaneously to workman, improve the technical scheme of safety production efficiency:
The special noise reducing apparatus of a kind of factory, main body is full-enclosed crash helmet, crash helmet both sides ear position is provided with denoising device, denoising device comprises division board and mounting box, division board is hemisphere face sheet metal, and division board indent side is movably arranged on mounting box one end in a spiral manner, and mounting box is right cylinder, run through and be arranged at crash helmet both sides ear position, mounting box and crash helmet sidewall keep vertical.
As preferably, division board diameter is greater than mounting box diameter of section 5 ~ 20mm, and rubber-coated limit, division board edge also and retains the space of 1 ~ 10mm between crash helmet surface.
As preferably, mounting box inside is provided with the cavity running through mounting box upper and lower surface, and cavity inside is provided with dividing plate, is filled with Sound-proof material between dividing plate side and division board in gap, and the mounting box sidewall of dividing plate opposite side is provided with several through holes.
As preferably, also comprise annular protection pad, the mounting box that protection pad is fixedly installed, near arranging on the end face of through hole, is provided with soft inserts in protection pad.
As preferably, also comprise separation layer, separation layer is fixedly installed on crash helmet inside, separation layer filled with gas, and separation layer and mounting box outer wall are interconnected.
The beneficial effects of the utility model are:
(1) the utility model structure is simple; the basis of traditional full-enclosed crash helmet is improved; enable to protect workman's hearing healthy by increasing noise insulation equipment simultaneously; reduce the proper communication healthy negative effect brought not being affected simultaneously to workman, improve safety production efficiency.
(2) the utility model division board diameter is greater than mounting box diameter of section 5 ~ 20mm, rubber-coated limit, division board edge and and retain the space of 1 ~ 10mm between crash helmet surface, its isolation effect is better, reduces outside sound wave and conducts to user ear by crash helmet outer wall.
(3) in the utility model, mounting box inside is provided with the cavity running through mounting box upper and lower surface, cavity inside is provided with dividing plate, be filled with Sound-proof material in gap between dividing plate side and division board, optimize soundproof effect further, reduce user ear and be directly subject to external noise stimulation.
(4) also comprise annular protection pad in utility model, avoid user in use owing to wearing the stimulation caused ear skin for a long time, improve experience.
(5) also comprise separation layer in utility model, the external sound source that whole crash helmet can receive is isolated by separation layer, and soundproof effect is outstanding.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
