Description
Technical field
The utility model relates to a kind of steady arm for water sample acquisition device, specifically a kind of depthkeeping original state water sample sampling steady arm.
Background technology
Along with the development of the modern industry, environmental pollution produces thereupon, and water pollution is also more and more taken seriously, in order to ensure the sustainable development of water resource, to the detection of water body with investigated into requisite work.To in waters containing in the water quality process of analyzing and researching of volatile matter, oxygen sensitivity material, collecting Hi-Fi water sample sample is the prerequisite truly reflecting sample characteristic, and this also just has higher requirement to water sampling system.
Existing sampling apparatus is normally inserted sampling container in water and is drafted the degree of depth, after water sample enters and is full of sampling container, is left the water and pours in sampling bottle and preserve.But in sampling process, current can cause certain impact to sampler, make sampler shake, and depart from the position of drafting, thus cause larger error to water sampling.
Utility model content
The purpose of this utility model is just to provide a kind of depthkeeping original state water sample sampling steady arm, easily shakes and cause the problem that institute's water sampling error is large with the sampler solving existing harvester when gathering water sample.
The utility model is achieved in that a kind of depthkeeping original state water sample sampling steady arm, comprises interpolation pole, is socketed in sliding sleeve on described interpolation pole and some extension rods;
Described interpolation pole is stainless pipe, and be connected in one end of described interpolation pole and prick rifle head, the root size of described bundle rifle head is greater than the external diameter of described interpolation pole, and be sealed with end at the other end of described interpolation pole stifled, the center stifled at described end has screw;
Described extension rod be isometric with described interpolation pole, etc. thick stainless pipe, described in every root, two ends of extension rod are all sealed with to hold and block up, the center stifled at described end has screw, and the butt end between described interpolation pole and described extension rod or the butt end between two described extension rods are all linked together by wire rod thread;
Described sliding sleeve comprises sleeve pipe and is fixed in the baffle of described its lower end, and described sleeve pipe is all slidably socketed on described interpolation pole, and described baffle is positioned at the top of described bundle rifle head; The tube wall of described sleeve pipe has sampler fixed orifice.
The xsect of described baffle is fusiformis, comprise the end facing water all in cusped edge shape and backwater end, the two sides of baffle with the place plane of end facing water and backwater end for axial plane is symmetrical, the length of described baffle is 4 times of described sleeve outer, the breadth extreme of described baffle equals the external diameter of described sleeve pipe, the axis of described sleeve pipe is near the backwater end side of described baffle, and the lower edge of described baffle presents curved arc to backwater end.
Described sampler fixed orifice is arranged on the top of described baffle backwater end, has one can insert the perps that screwdriver carries out tightening operation in the tube wall side of the relatively described sampler fixed orifice of described sleeve pipe.
Be provided with rolling disc in the centre of described screw mandrel, the hand of thread spiral be positioned on the screw mandrel of described rolling disc both sides is contrary.
When carrying out sample collection, first sampler being screwed is connected on sliding sleeve, then compound rod is connected to form with interpolation pole again after being connected successively by some extension rods, the total length of compound rod is a bit larger tham from sampling work face to the distance intending sampling water body bottom surface, the bundle rifle head of interpolation pole is inserted water body bottom surface certain depth, keep compound rod motionless, the sliding sleeve being connected with sampler is steadily picked up, make baffle downward, sleeve pipe is slowly enclosed within extension rod topmost, and make sampler side towards the direction in river downstream, transfer sliding sleeve, sliding sleeve is slowly gone downwards on interpolation pole along extension rod, thus sampler is slipped into together with sliding sleeve in water body, draft the degree of depth, sampling can be started after water body environment restores balance.
The utility model is mainly used in the collection of depthkeeping original state water sample in torrent waters, can effectively prevent in sample collection process sampling apparatus by current punching partially or the situation of rocking occur, operate miss when reducing or avoid sample collection; And smart structural design of the present utility model, current slowly change at the streamline at this steady arm place, can avoid because producing air pocket and cause the situation that the volatile matter in water overflows in sampler water inlet, thus raising gather the fidelity of water sample.
