Abstract
The invention relates to a shallow water quality sampler and aims at solving the problem of insufficient representativeness of a water sample caused by the damage of a sampling bottle of the existing water sampler to a water flow field. The shallow water quality sampler comprises a handheld rod, wherein a sampling bottle is arranged at the bottom end of the handheld rod in a clamping manner. The shallow water quality sampler is characterized in that a sampling bottle body is perpendicular to the handheld rod and arranged horizontally, and two sides of the sampling bottle are respectively provided with a water inlet valve which can be opened and closed. According to the shallow water quality sampler, a universal connection structure is adopted for fixing the sampling bottle, so that the direction of the sampling bottle can be automatically adjusted along with the water flow. The sampling bottle is arranged horizontally at the bottom of the handheld rod, and the water inlet direction is conformed to the direction of the water flow and the stability of the water flow field is maintained, so that the representativeness of the water sample is high; and a universal adjustable fixing mode is adopted for fixing the sampling bottle, so that the direction of the sampling bottle can be adjusted along with the water flow when water at a part in which the water flow is difficult to judge is sampled, and the stability of the water flow field is maintained; and two ends of the top of the horizontal sampling bottle are respectively provided with an exhaust valve which is capable of smoothly and safely exhausting gas during water sampling, so that the water is prevented from being affected by the gas in the sampling bottle.
Description
Technical field
The present invention relates to a kind of water quality monitoring technology apparatus field, specifically a kind of shallow water water sampler.
Technical background
With interior shallow waters, sampler both domestic and external mainly is divided into full-automatic unmanned sampling equipment and manpower sampling equipment for the 5m degree of depth.Full-automatic unmanned sampling equipment cost and maintenance cost are expensive, and the manpower sampling equipment adopts the single port vial more, can't solve the technological difficulties of sampler exhaust in water, a kind of water sampler of CN2833554Y patent such as Patent Office of the People's Republic of China's bulletin on November 1st, 2006, the CN201935826U patent that on August 17th, 2011 was announced: a kind of water sampler, the water sampler that above-mentioned two patent documents are put down in writing all adopts the single port bottle to be fixed on the handle and fetches water, the single port bottle is difficult to the air of sampling jar is emptying in the water intaking process, and stop at the bottom of current are subjected to bottle in the single port bottle water intaking process, destroy water flow field, affected the representativeness of water sample.
And the CN101464226A patent document of Patent Office of the People's Republic of China's bulletin on June 24th, 2009, name is called shallow water type water quality measurement sampler, this device adopts the up and down sampling jar of both ends open, solve to a certain extent sampling jar exhausting problem in water, but this invention sampler Inlet and outlet water is above-below direction, vertical with water (flow) direction, destroyed water flow field in the water intaking process, same Shortcomings aspect water sample representativeness and reliability.
Summary of the invention
The object of the invention is to destroy the problem that water flow field causes the representative deficiency of water sample for the sampling jar of present water sampler, a kind of shallow water water sampler that can comply with water (flow) direction is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of shallow water water sampler, comprise holding rod, and the bottom of holding rod is folded with sampling jar, and the sampling jar body is vertical with holding rod to be horizontal placement, and the both sides of sampling jar are respectively equipped with water intaking valve to be opened/closed.Holding rod is stretched in the water the predetermined degree of depth, the both sides Parallel to the flow direction of sampling jar band valve is placed, open water intaking valve after, current flow in the sampling jar, cross certain hour after valve-off mention holding rod, sampling is finished.Current turnover sampling jar direction is consistent with water (flow) direction in the sampling process, makes the process of sampling jar water sampling not destroy water flow field, and water sample is more representative.
As preferably, described holding rod comprises interconnective shaft and geometrical clamp, and sampling jar adopts universal connection structure to be installed in the bottom of geometrical clamp.In the water intaking of the zone of some streamflow regime more complicated, water (flow) direction is difficult to accurate judgement, inconsistent with the water (flow) direction placement when adopting the sampling jar of fixed-direction probably to fetch water, destroy water flow field, sampling jar adopts universal connection structure to install, when device for fetching water from stretches in the water behind the certain hour, the sampling jar opening direction is regulated with water (flow) direction automatically, guarantees that water sample is representative.
As preferably, described geometrical clamp and shaft are rotationally connected, and geometrical clamp rotates take shaft as axle, and described geometrical clamp and sampling jar adopt the flexible connection that can swing up and down.Being rotationally connected of geometrical clamp and shaft, sampling jar can be done rotation on the surface level with fixed mount according to water (flow) direction, and sampling jar can swing up and down fine setting according to flow direction simultaneously.
As preferably, the bottom of described shaft adopts ball pivot to be connected with the top of geometrical clamp.Ball pivot not only can rotate but also have certain swing degree of freedom, and have very high sensitivity, can regulate rapidly the sampling jar direction.
As preferably, the swing activity point of view of described ball pivot is in 60 degree.Limiting swinging angle avoids the strength of current to cause the undue perk of geometrical clamp to affect the water intaking degree of depth and the water intaking angle of sampling jar.
As preferably, the two ends of the upper side of described sampling jar are respectively equipped with vent valve to be opened/closed.Sampling jar is horizontal when arranging, the top of sampling jar is gathered easily bubble and is difficult for discharging, especially the bore of water intaking valve is less than the size of sampling jar body, the very difficult discharge of the top gas of sampling jar and bubble accumulate in the both ends of sampling jar top side easily, therefore at the upper side two ends of sampling jar vent valve is set respectively, vent valve is controlled by backguy, opens and closes vent valve and carry out exhaust in the process of water sampling.
As preferably, a backguy synchro control switching is adopted in the interlock of the water intaking valve of described sampling jar both sides.
As preferably, be provided with the backguy runner on the holding rod, the upper end of described backguy is fixed on the runner, and described geometrical clamp is provided with deconcentrator, and the lower end of backguy connects respectively two water intaking valves by deconcentrator.
As preferably, the outside of described water intaking valve also is provided with the screen pack that stops foreign material.
As preferably, described holding rod shaft is provided with scale and indicates.
Sampling jar of the present invention is horizontal setting in the holding rod bottom, makes into water direction-adapting water (flow) direction, keeps water flow field stable, and water sample is more representative; The universal adjustable fixed form of the fixedly employing of sampling jar is difficult to judgement place water intaking at current, and sampling jar can be regulated direction with current, keeps water flow field stable; At horizontal two ends, sampling jar top vent valve is set, can smoothly fully exhaust in the water intaking process, avoid the gas in the sampling jar that water sample is exerted an influence.
