Abstract
The invention relates to a deep water type water quality measurement multi-point sampler comprising a power supply, a display instrument, a control switch, an upper-and-lower linkage valve, a liquid level transducer, and a sampler main body consisting of four sampling bottles; the sampling bottles are fixed by fixing rings, and then fixedly connected to the steel cable part at the bottom end of the cable connecting wire; the liquid level transducer at the bottom end of the cable conductor converts a water body signal in the sampling bottles into an electrical signal which is transferred to the display instrument for display through the integrated control switch; and the upper-and-lower linkage valve is merged into the cable conductor through a linkage valve control wire, and then connected to the control switch. The arrangement of the upper-and-lower linkage valve overcomes the technical difficulty in gas discharging in the prior deep water sampling; due to the modularized composition, the sampler is convenient and quick to assemble; the quantificational water sampling can be carried out at definite depth; the problem that the prior single-port water collection causes damage to the flow field is solved; and meanwhile, the valve can be switched on or off instantaneously, and the leak prevention effect is good. Therefore, the efficiency and the accuracy of deep water sampling are improved. With good practicability, the invention is easy to popularize and apply.
Description
Technical field
The present invention relates to environmental water quality monitoring and hydrology measuring technology, relate to a kind of novel sampler of deep water type water quality measurement multiple spot that is used for monitoring analysis water body quality particularly.
Background technology
Along with the increasing of the intensity of water resources development and utilization and speed and the enhancing day by day of people's ecologic environment consciousness, both at home and abroad water environmental problems is paid attention to gradually, at present domesticly estimate in the related work all water environment as emphasis at environmental protection and project environment.Whether healthy as the water quality key element of water environment evaluation index is to weigh waters destructiveness and potable water important indicator, and water-quality guideline can provide reliable foundation for environmental protection accurately, and wherein water sampling is an important working link.It is not simply to carry out water sample to collect, and as representative for the water sample of analyzing, and can accurately reflect the concentration of water quality parameter and index [Chi Jing etc. the quality assurance measure in the environmental water sample gatherer process [J]. environmental monitoring management and technology, 2007,2:57～59].The factor that influences water sampling has a lot, as preservation of sampled point, sampling instrument, sampling volume, the method for sampling and even water sample etc., the variation of any one factor all may cause analysis result change [Zhang Jingdong. the step-water sampling [J] that water quality monitoring can not be despised. the Yunnan environmental science, 1996,6:59～60].So how to make the water sample of collection reflect the water quality situation truely and accurately, be the problem that monitoring analysis work at first must solve.Because ocean, lake bottom water body have decisive influence [yellow classics for the absorption and the release of pollutant, Li Jia etc. silt content is to water body oxygen consumption organic pollutant degradation oxygen consumption influence [J]. people the Changjiang river, 2005,4:55～57], and pollutant also is the important indicator [Li Hong of reflection water pollution situation at the Changing Pattern of the vertical depth of water, Li Jia etc. the fractal surface of silt and FRACTAL ADSORPTION MODEL [J]. the water conservancy journal, 2003,3:14～17], therefore can carry out matter of utmost importance and the technological difficulties that water sampling is a monitoring water environment by depthkeeping.
China has the maximum hydraulic power potentials in the world, and particularly the scale of west area hydroelectric development enlarges year by year.Build the power station and just form huge deep water reservoir, and just bring many environmental problems thus.Wherein, the formation of reservoir has changed the distribution of water temperature rule in original river course, lower and the vertical water temperature of profundal zone water temperature of nearly bottom of the reservior has obvious variation, this irrigation to hydrobiont growth and breedings such as fish and littoral crops can produce very and seriously influence [Deng Yun, Li Jia etc. reservoir temperature difference density current Study of model [J]. the water conservancy journal, 2003,7:7～11].Simultaneously, influenced by water temperature delamination and the variation of the Pollutants Diffusion rule that causes; Nearly bottom of the reservior bed mud all is crucial research topic to the pollutant release rule; And the reservoir life-span is produced material impact because the reservoir that flood season, silt caused includes the athletic meeting of husky muddy water.Therefore dye the variation of thing Diffusion Law at above-mentioned water ring; Nearly bottom of the reservior bed mud all is crucial research topic to the pollutant release rule; And the reservoir life-span is produced material impact because the reservoir that flood season, silt caused includes the athletic meeting of husky muddy water.Therefore at above-mentioned water environmental problems, must behind reservoir Cheng Ku, carry out sample analysis and study index [Deng Yun such as temperature, silt content and pollutant load water body, Li Jia etc. enter the silt carrying flow three-dimensional motion characteristic research [J] in lake. hydrodynamics research and progress A, 2001,9:295～302].This also just need be to the observation of taking a sample than the deep water body, traditional sampling means can only obtain surface water, lacks reliable means and carries out the deep water water sampling, and part adopts the mode efficient of the acquisition water sample that draws water lower, and the depthkeeping effect is relatively poor, and the analysis and research of water sample are afterwards had a negative impact.The robotization sampling machinery of external existing certain applications Yu Haiyang, but involve great expense and the engineering philosophy complexity, the maintenance cost height is difficult to promote.
Along with the development of China's western mountainous areas water power, mining industry equal energy source industry, also in order to satisfy an urgent demand of environmental protection, just press for that a kind of cost is reasonable, the simple acquisition instrument of principle of work, and enforcement of the present invention also just had real application value.
