Description

Protective survey warning system that Ship Building and Repairing welding personnel is wireless

Technical field

The utility model relates to a kind of monitoring system, is the wireless protective survey warning system of a kind of Ship Building and Repairing welding personnel.

Background technology

Ship Building and Repairing industry belongs to labour and technology-intensive industry, and in hull construction, account for 30% ~ 40% during hull construction chief engineer during Welder, welding cost accounts for 30% ~ 50% of hull construction total cost.Ship Welding workload is very large, and the butt-weld of ton oil carrier is at about 20KM; Ten ton oil carriers, butt-weld is at about 50KM; In addition, the large ships such as ton container ship, bulk carrier, car carrier, butt-weld is reaching about 30KM.

China's Ship Building and Repairing welding is main mainly with human weld, mechanism scholar (the Xu Yan such as Peking University in 2012, Gong Manman, Wang Jiao etc. electric welding UV radiation is to workman's harm and safeguard procedures cross-sectional investigation [J]. Peking University's journal (medicine), 2012,44(3): 448-453) investigate with regard to the harm of electric welding UV radiation to operating personnel.Study carefully the effective questionnaire of common acquisition 828 parts, wherein electric welder 721 people, auxiliary work 107 people.The symptom of facial skin lesions and sign incidence are scorching hot shouting pain (48.7%) from high to low successively, skin is itched (39%), pigmentation (31.9%), flush (25.4%), insensitive numbness (12%), macula papule (10.1%), verrucous vegetation (3.7%).In investigated workman, the people of 90% in the previous year in there is electric ophthalmia, the symptom of ophthalmic injuries by incidence be ocular pain (61.5%) from high to low successively, photophobia sheds tears (61.4%), blurred vision (50.2%), burn feeling (35.9%, foreign body sensation (32%), eyes twitch (12.2%).The incidence 438 workman's eye health check-ups being found to phacoscotasmuies is 15.8%, and the incidence of eyeground pathological changes is 2.5%.

It is second largest occupational illness outside pneumoconiosis that welder's electric ophthalmia that welding arc light causes is listed in, the risk factor not wearing face guard is 1.8 times that wear face guard, and carrying out the occasion of weld job many people simultaneously, be not engaged in the personnel of weld job, be equally easily subject to the injury of circumference arc optical radiation.Behavior when welding frequently appears in Ship Building and Repairing enterprise not with safety goggles or welding mask, arc light, splashing causes impaired vision, and skin histology injures even cutaneum carcinoma, has had a strong impact on healthy and work efficiency.The behavior do not sought fame and wealth for this violation weld job safety management specification, consciousness of self-protection must effectively monitor and manage, and stops the health hazards caused thus.
