Description
Technical field
The present invention relates to a kind of Rainwater Quality and analyze multi-access-like segment sampler.
Background technology
Due to improving constantly of industrialization and urbanization level, waste gas containing elements such as a large amount of sulfur, carbon enters air, these pollutions are brought into ground by rainfall, so the quality problems of rainwater are always between urban area public hazards and global environmental hazard, wherein especially prominent is exactly acid rain problem.At present, the research of acid rain is all attached great importance in countries in the world, the Crack cause including acid rain and the pollution to environment thereof.Rainwater matter quantifier elimination should be not only limited to acid rain by us, comprise other various indexs and various can to the factor of environmental effects.When current rugged environment problem causes haze weather, people always look forward to raining taking away haze, hardly realize that the rainwater being contaminated also is very large to endangering produced by environment and the mankind.
The quality of water is closely bound up with the life and health of the mankind.Along with the development of urban construction, the pollution in city is also increasingly severe.Most of people lack correct cognition for polluting of rainwater.China has carried out the research to city rainfall runoff pollution of area source in phase early 1980s in Beijing, starts late.In order to allow more people recognize the rainwater pollution to environment, it is necessary to what allow everybody regains consciousness recognizes so clean unlike in the imagination of rainwater (including snow).Simultaneously again in order to better control the various pollutions of rainwater, it is necessary to understand pollution in rainwater and be how that produce and pollutant levels variation characteristic, grasp its Changing Pattern.And; the task of top priority of two Conferences in this year is promptly to revise Law on Environmental Protection; and atmospheric pollution, water pollution and prevention and control of environmental pollution by solid wastes method; accelerate to formulate the laws such as soil temperature and soil moisture content; formulate and improve relevant environment standard, improve Topics on Topics Amount Control Of Pollutant Discharged and pollution control franchise operation system.Measuring and studying its impact on environment rainwater quality, has responded two Conferences and has striven substantially solving with 10-20 the call of China's problem of environmental pollution.
At present, a lot of cities are rain rainfall detecting instrument all, but the rainwater quality determination being a lack of a system is collected instrument and rainwater is collected, and rainwater quality carries out the mensuration in later stage.It would therefore be desirable to have rainwater is collected by a device, and can collecting the rainwater of rainy different periods, the rainwater of different periods is carried out rain matter measurement by the later stage, thus studying rainwater to the pollution of environment and impact.
Summary of the invention
The present invention is directed to the problem that current rainwater rainfall detecting instrument lacks rainwater Fractional Collections, it is proposed that the Rainwater Quality of a kind of energy Fractional Collections rainwater analyzes multi-access-like segment sampler.
Rainwater Quality of the present invention analyzes multi-access-like segment sampler, it is characterized in that: include raingauge receiver, drainage system, sampler, casing with side door, it is fixed on casing upper end bottom described raingauge receiver, and described raingauge receiver is connected with the sampler being placed on cabinet base by the drainage system being placed in casing；Described drainage system includes the arm for connecting, shunt conduit for connecting with sampler with raingauge receiver, described arm is along the multiple tapping hole of arm axial arranging, the corresponding shunt conduit of each tapping hole, the bottom outlet of every shunt conduit is furnished with a sampler, and along arm front end water inlet to shunt conduit water inlet increasing height corresponding to arm outlet water at tail end mouth.
The axis of described arm and horizontal angle are acute angle, and water inlet distance base in arm front end is apart from minimum.
Described shunt conduit equidistant arrangement, and all of shunt conduit be arranged in parallel.
Described arm is equipped with corresponding barb with corresponding shunt conduit intersection.
Described raingauge receiver is flared structure, and the cross section of described raingauge receiver upper end water inlet and lower end outlet is circle.
Described base is provided with the groove for placing sampler.
Described sampler is the sampling bottle with sealing rubber plug.
Concrete, whole instrument height 1.6m, the water inlet cross-sectional diameter d of wherein said raingauge receiver1For 1m, raingauge receiver outlet d2The circular outlets that cross section is diameter 20cm, and the height h of raingauge receiver1For 0.3m；Described arm axis and horizontal line angle α are 26.565 degree, and length to height ratio is 2:1, and the spacing d of adjacent shunt conduit3For 6cm；The height h of described casing21.3m, long 1m, wide 0.5m；The diameter d of described arm and described shunt conduit4For 2mm；The long I of described base11.2m, wide I20.5m, described base is provided with 8 grooves for placing sampler, groove diameter d5For 6cm；Described casing side door length 0.6m, high 0.3m.
Work process: before raining, first has to put into sampler in the base groove of this device.Rainwater enters device by raingauge receiver, flows in the shunt conduit that water inlet height is minimum again through arm, and when the sampling bottle corresponding to this pipeline takes after completely, rainwater will overflow, and flow to next isocon, allows next one sampling water bottle be sampled.Constantly go on successively, the rainwater of different periods is collected.
The invention has the beneficial effects as follows: realize the rainwater of different periods is carried out quantitative collection, adopt the device of pipeline shunt, rainwater is carried out according to quantity segmentation；It is capable of the rainwater of different periods is collected, collects the rainy initial stage, rain mid-term, the rainwater in later stage of raining.Can be taken away by rainwater owing to air being mingled with pollutant, by the collection of rainwater is measured by these different periods, be more beneficial for research rainwater to the impact of environment and pollution level.
