Description
Technical field
The present invention relates to a kind of sampler, specifically refer to a kind of water body sampler.
Background technology
Water sampling is the modal work of the department such as environmental protection, epidemic prevention, and mostly current water sampling is to be undertaken by sample bucket or sampling cup.With the sample bucket used at present or sampling cup when carrying out water sampling, if operation is relatively easy when locality going up water surface sample, hand-held mode direct sample can be adopted.But when gathering some human bodies and cannot contacting the water body sample of the water surface, as the water body sample of deep well, often need by pulling rope sample bucket or sampling cup to be put to sample to water body.According to epidemic prevention standard, the water body taking out the distance water surface 2-5 rice degree of depth is needed to chemically examine as sample to the sampling of Character in Drinking Well Water, and adopting traditional sampling apparatus due to the effect of buoyancy, sample bucket or sampling cup are difficult to the degree of depth of being down to water surface following provisions, do not reach the object of deep water sampling.Application number: 201120544166.1, title: deep water sampling bucket, following technical scheme is disclosed: deep water sampling bucket in this patent document, comprise a staving, bung fixes pulling rope, it is characterized in that: described staving, its density of material is greater than water-mass density, is provided with crosspiece at bung, manhole is had bottom staving, through hole is provided with cover plate, cover plate and staving bottom resilient hinged, on the cover board steady brace, pull bar extends upwardly to bung, a hinged hook on pull bar top, hang on the crosspiece of bung, hook is provided with the rope that breaks off relations.This deep water sampling bucket owing to being provided with through hole bottom staving, and the impact that can overcome water body buoyancy utilizes the weight of staving to sink in water, is namely plugged within sample bucket when reaching sampling water layer rear enclosed through hole water sample.But there is following technical matters in this deep water sampling bucket: 1, the folding of staving bottom cover plate is controlled by the hook on pull bar top, and hook and the clutch of bung crosspiece adopt, and breaking off relations restricts controls, in actual mechanical process, break off relations when rope is transferred with pulling rope and be easy to produce winding, after being wound around, pulling unhook rope to be easy to cause and to break off relations unsuccessfully, directly causing water sampling failure; Drawing being easy to cause break off relations to restrict in the process of rope with pulling rope below that break off relations in addition, after pulling rope hose tool, staving bottom cover plate closes by mistake, causes staving to enter water failure by mistake.2, this deep water sampling bucket is adopted to be difficult to accurately control the sampling depth of water body, although scale can be arranged to be indicated on pulling rope rope body, but when carrying out deep well sampling, if the height of water surface distance well head can not be learnt, the underwater penetration of sample bucket cannot be calculated.
Summary of the invention
For overcoming the technical matters that the deep water sampling bucket that uses at present in use exists, the invention provides a kind of rational in infrastructure, water body sampler that automaticity is higher.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: water body sampler, comprise a sampling cup, the bottom of sampling cup has manhole, through hole is provided with cover plate, cover plate and staving bottom resilient hinged, it is characterized in that: also comprise sampling glass stand, it is inner that sampling cup is positioned at sampling glass stand, fixes pulling rope at the top of sampling glass stand; Described pulling rope is provided with the magnetic induction cover that can be free to slide, and the floatability of magnetic induction cover is on the water surface, and fix some Hall elements in the inside of pulling rope successively by setpoint distance, each Hall element is electrically connected with the controller of pulling rope tail end respectively; Bottom sampling glass stand, be provided with a magnetic induction coil, be provided with a magnetic post at the back side of described cover plate, after cover plate opens, the top of magnetic post and magnetic induction coil is just right, and the electric power conductor of described magnetic induction coil is electrically connected with controller through pulling rope inside; The density of material of described sampling cup, sampling glass stand is greater than water-mass density.
