Summary of the invention
The technical problem to be solved in the present invention is: providing a kind of can sample and the simple water quality monitoring sampler of structure by the set depth in waters, and provides a kind of sampling method adopting aforementioned sampler.
In order to solve the problems of the technologies described above, water quality monitoring sampler of the present invention comprises shank, sampling jar and the floating drum for keeping afloat, sampling jar comprises valve body, spool and bottle, the top of bottle is provided with water inlet, valve body comprises cylinder shell, the end face of housing is provided with lifting hole(eyelet), the sidewall of housing is provided with window of receiving water, the lower end of housing is connected with the threaded upper ends of bottle, what spool was up and down is arranged in housing, floating drum connects spool by the bracing wire through lifting hole(eyelet), fishing rod connects valve body by fishline, when spool moves to lowermost position in housing, spool blocks the water inlet of bottle, when spool moves to upper in housing, window of receiving water on housing is communicated with the water inlet of bottle, the density of each parts of sampling jar is all greater than the density of water, the gravity of sampling jar is greater than sampling jar and is in completely under water and the buoyancy of bottle suffered by sampling jar during empty bottle, the gravity of bottle and valve body is greater than sampling jar and is in completely under water and the buoyancy of bottle suffered by bottle during empty bottle and valve body.
For preventing bottle prestoring water in water inlet front valve shell, the lower end of described window of receiving water extends to the position that housing is threaded with bottle.
Tilt to prevent sampling jar, described sampling jar also includes spider, spider is fixed on the end face of housing, spider comprises multiple leg, the upper end of all legs links together, scatter outwardly in the lower end of all legs, the lower end of each leg of spider is all fixed on the end face of housing, the upper end tie point of the leg of spider is positioned at directly over housing end face center, fishline is fixed on the upper end tie point of the leg of spider, fishline is connected with valve body by spider, the two ends of bracing wire connect the center of spool end face and the center of floating drum bottom surface respectively.
In order to be suitable for different sampling depth samplings, described bracing wire is length-adjustable line.The length of bracing wire can be regulated according to the sampling depth of setting, thus make a sampler can get the sample of the multiple degree of depth.
For the ease of observing whether get full sample, described floating drum is marked with full water graticule, sampling jar and floating drum are put into water, and when sampling jar submerged fills water and full water graticule on floating drum reaches the water surface, suffered by sampling jar and floating drum, buoyancy of water equals the gravity of the two.When there is no full water graticule, can by observing the draft of floating drum, when the draft of floating drum stablize constant after, illustrate and get full sample.
Water quality monitoring sampling method of the present invention, comprise the steps: that (1) adopts aforesaid sampler, fish sampling jar with fishing rod, the point that sampling jar is selected from waters puts into water, floating drum floats on the surface, (2) bottle to be sampled drops to bracing wire pulling spool, and bottle continues to decline with valve body, and bottle water inlet is communicated with window of receiving water on valve body, water enters bottle, when the full water graticule on floating drum reaches the water surface, fill water in bottle, mention fishing rod and fish out sampling jar.
The invention has the beneficial effects as follows: sampler of the present invention controls the closedown of sampling water inlet by spool, and spool and valve body relative position are controlled by floating drum, make use of the buoyancy of each parts and the relation of gravity fully to reach a kind of self-equilibrating, realize automatic sampling, and calculate each part dimension according to setting sampling depth, thus reach and sample at set depth, due to bottle water inlet of the present invention from being opened between closedown, the bottle degree of depth has certain floating, therefore, setting sampling depth is not an exact value but a very little scope, the present invention is suitable for having requirement to sampling depth and require it is not use under point-device condition.The present invention does not need electrical control, and structure is simple, and sampling is convenient.
