Summary of the invention
The technical matters that the utility model will solve provides and a kind ofly not only when gathering water sample, meets the environmental monitoring standard, and simple in structure, easy to operate, be easy to clean and water-quality sampler that sampling efficiency is high.
For solving the problems of the technologies described above; The utility model adopts a kind of like this water-quality sampler; It comprises that a sampling cylinder with opening end and one are fixed on suspension bracket said opening end, that be used for suspension cord; This water-quality sampler comprises that also one can be opened sampling cylinder bottom, the water sample automatic acquisition device that after water sampling is accomplished, can close the sampling cylinder bottom automatically automatically when gathering water sample.
A kind of preferred implementation as the utility model; The bottom of said sampling cylinder offers a through hole; Described water sample automatic acquisition device is by the piston that is arranged on said through hole, the piston seat that is arranged on said sampling cylinder bottom outside and can cooperates with said piston seal, and is arranged on said sampling cylinder bottom inside and is used for go up and down guiding and spacing piston guide of said piston and be configured to; Said piston seat is connected with said sampling cylinder bottom seals.
In the utility model; Described piston preferably is inversed taper platform shape; Said piston seat is provided with a size and the suitable inversed taper platform shape through hole of said piston, the arc that said piston guide frame axially is provided with by three said sampling cylinders in edge be arranged on baffle plate said arc top, that extend radially inwardly along said sampling cylinder and constitute; The bottom of said arc is fixedly connected with the bottom of said sampling cylinder, and the internal diameter of the cylindrical cavity that said three arcs constitute and the stub end diameter of said piston are suitable, and said piston seat is connected with said sampling cylinder bottom seals through sealing gasket.
After adopting said structure; Because being provided with one, the utility model when gathering water sample, can open the sampling cylinder bottom automatically;, water sampling can close the water sample automatic acquisition device of sampling cylinder bottom after accomplishing automatically; This device is preferably by the piston that is arranged on sampling cylinder bottom through-hole place, the piston seat that can cooperate with piston seal and be used for that piston goes up and down to lead and spacing piston guide is configured to, and piston seat is connected with the sampling cylinder bottom seals.Like this when entering river, lake, ocean etc. and gather water sample, because deadweight when sinking under the water, piston floats along the piston guide frame under buoyancy when sampling cylinder; In piston come-up time,, water sample gets into from the through hole of sampling cylinder bottom, when sampling cylinder is filled when moving upward under water sample and the traction at rope; Piston is sealed and matched along the sinking of piston guide frame and with piston seat under the effect of hydraulic pressure, thereby accomplishes the collection of water sample, therefore; The water sample that the utility model is gathered not only meets the environmental monitoring standard, and sampling efficiency is high, has improved the accuracy and the sampling efficiency of sampling; And simple in structure, easy and simple to handle, clean also very convenient.
