Description
Technical field
The utility model relates to a kind of PM2.5 monitoring equipment, particularly a kind of PM2.5 monitoring equipment that has utilized sun power to power, have environmental protection concept.
Background technology
In recent years, problem of environmental pollution often causes occurring the inclement weathers such as grey haze, haze, and PM2.5 also progressively pays close attention to for people and payes attention to.PM is the abbreviation of " particulate matter ", can be suspended in the air for a long time.Above-mentioned PM2.5 fine particle claims again particulate, fine grained, can enter the lung particle, refers to that particle diameter is less than or equal to 2 μ m(in the atmosphere sometimes use less than 2.5 μ m, i.e. PM2.5) particle.Although fine particle is content component seldom in the earth atmosphere composition, it has important impact to air quality and visibility etc.Compare with thicker particle, PM2.5 is rich in a large amount of poisonous and harmful substances, threat to health is larger, very easily be attached to deep lung, and can in atmosphere, stop the longer time, fed distance is also farther, and is also larger on the impact of atmospheric environment and health, is the main assailant who causes black lung, grey haze and haze weather.
The Enemy of the State that PM2.5 has now become is widely known, the look of what is said or talked about becomes is in time announced the PM2.5 data, will be conducive to guide better the public health trip, allows everybody for different air quality states, takes different safeguard measures, reduces as far as possible harm.In February, 2012, also increased especially the fine particle monitoring index in " ambient air quality " of the new revision of State Council.In February, 2013, national scientific and technical terminology validation board claims: PM2.5 intends definite designation and is " fine particle ", and PM2.5 mainly comes from tail gas, smoke stack emission, soil airborne dust, sandstorm and the volcanic debris of the truck of burning diesel oil.
In view of PM2.5 can damage respiratory system and cardiovascular system; cause asthma, lung cancer, angiocardiopathy, inborn defect and dead too early; now popular very high to the PM2.5 attention rate; also need in time to understand the information of this respect; with the measure of properly protecting; protect the health of self, thus, the PM2.5 monitoring equipment also begins to install successively in each city.
But traditional PM2.5 monitoring equipment generally need to provide power supply by alternating current, and owing to use out of doors, long-time experience is exposed to the sun and rain, and causes easily the damage of monitoring equipment, has affected monitoring effect and measuring accuracy, also can shorten the serviceable life of product.
Along with the in recent years frequent outburst of energy crisis; the exploitation of the clean environmental protection such as sun power, regenerative resource, utilization come into one's own day by day; and the PM2.5 monitoring equipment generally all is arranged on eminence; the present position has the advantages that lighting effect is good, the solar cell output power is high, thereby makes sun power have good using value in this field.
Summary of the invention
The utility model is exactly the weak point for existing PM2.5 monitoring equipment, and a kind of PM2.5 monitoring equipment that has adopted solar powered pattern, environment-friendly type is provided.
For achieving the above object, the utility model provides following technical scheme.
