Abstract
The invention discloses a multi-layer sampler for an underflow layer. The multi-layer sampler comprises a conical head, an outer pipe, an inner pipe, sampling pipes, a sampling bottle, a manual air extracting device, a protective cover and a hammer. The multi-layer sampler is characterized in that the upper part of the conical head is connected with the outer pipe and the inner pipe; the sampling bottle is respectively connected with the inner pipe and the manual air extracting device through the sampling pipes; the protective cover additionally covers the top end of the outer pipe; and the protective cover is knocked by the hammer to enable the inner pipe and the outer pipe to enter the underflow layer. The sampling pipes are fixedly arranged in small groove regions (with different heights) inside the inner pipe according to a sampling requirement so as to collect water samples at different heights. During sampling, the water samples are sucked from the inner pipe to the sampling bottle under the negative pressure which is generated by extracting air in the sampling bottle by using the air extracting device. The multi-layer sampler for the underflow layer is mainly applied to the collection of underflow layer water samples of rivers, lakes and invertebrates, and is particularly applied to the layered collection of underwater underflow layer water samples.
Description
Technical field
The present invention applies to the collection of river and lake undercurrent layer water sample and invertabrate, is particularly useful for the layering collection of undercurrent layer water sample under water.
Background technology
At present, the utilization of undercurrent layer sampling thief is mainly seen in abroad, does not domesticly see relevant device.Retrieval correlative study document, the method for undercurrent layer sampling has mainly experienced following several stages: directly dig pit at sampled point and gather the water sample (Chappuis 1942) that flows in the hole; The vertical tube sampling is installed water sample (the Bou and Rouch 1967 that vertical tube extracts certain depth at sampled point; Palmer and Strayer 1996); (Williams and Hynes 1974) gathered earth and the water sample of sampled point in core pipe sampling (Core sampling) together; Freezing sampling (Freeze coring) is freezed back integral body with sample area and is taken (Stocker and Williams 1972 away; Hynes 1974; Bretschko 1985); Settle the method (Tabacchi 1990) of artificial matrix at sampling site.
Wherein using is the vertical tube sampling method more widely, and the Bou-Rouch sampling thief is vertical tube sampling thief the earliest, is designed by Bou and Rouch.Bou-Rouch sampling thief and modified thereof (Valeria Lencioni 2008; Oana Teodora Moldovan 2011) all can not gather the water sample of different depth simultaneously, also be not suitable for underwater undercurrent layer sampling (the process mesexine water that inserts the undercurrent layer can influence sampled result in the inflow pipe), and limited by undercurrent layer water cut.
Summary of the invention
The present invention not only can gather valley flat and reach the undercurrent layer water sample of a certain degree of depth under water, also can gather the water sample of different depth simultaneously, and is subjected to the restriction of undercurrent layer water cut less.
For realizing above-mentioned functions, the present invention adopts following technical scheme: undercurrent layer multi-layer sampling thief comprises conehead, outer tube, interior pipe, sampling pipe, sampling bottle, air extractor, protective cover and hammer.
Conehead is stainless steel, links to each other by screw thread with interior pipe bottom, and outer tube sleeve is stuck in the smooth of the recessed section of conehead outside interior pipe, and conehead helps to insert the undercurrent layer.
Inner and outer pipes, be stainless steel, interior pipe is than the short 200mm of outer tube, keeps 2-4mm between the inner and outer pipes at interval, interior pipe 4 the little troughed belts that distribute at various height, between two bands every 100mm, little troughed belt is by wide 5mm, long 10mm, and the vertical array sulculus of 5mm at interval constitutes, pipe in the water of undercurrent layer is flowed into by these sulculuses, interior pipe bottom tool female thread portion links to each other with conehead; Outer tube mainly is safeguard function, bears downward pressure on the one hand in the process of inserting the undercurrent layer, pipe in also the prevention river bed water is invaded in the process of inserting simultaneously, and outer wall has the scale of display depth.Water sample is gathered from interior pipe, and sampling pipe stretches into and be fixed on corresponding height from interior pipe top, can gather the undercurrent layer water sample of a certain degree of depth during sampling simultaneously, also can gather the water sample of different depth simultaneously.Owing to adopt the method for gathering water sample in the pipe in sampling pipe stretched into, with piston pump is directly installed in compare the inconvenience when having avoided undercurrent layer moisture content less like this on the pipe.
Sampling pipe is the PVC flexible pipe, is divided into two sections, pipe certain height in first section one end is fixed on, and the other end links to each other with sampling bottle; Second section connects sampling bottle and air extractor.
Sampling bottle is glass or PVC material, has one two interface to link to each other with sampling pipe on the bottle cap, and one links to each other with air extractor.Sampling bottle can be changed different volumes according to the research needs.
Air extractor adopts two-way manual suction pump, produces negative pressure by the gas that extracts in the sampling jar, and the water sample of interior pipe is extracted in the sampling jar.
Protective cover is stainless steel, is installed in the outer tube top, plays protective action in the process of vertical tube being pounded the undercurrent layer, and protective cover leaves 4 strias that supply sampling pipe to stretch out.
Hammer is used for inner and outer pipes is knocked in the undercurrent layer, selects suitable hammer as required.
The invention has the beneficial effects as follows, inner and outer pipes is being inserted in the process of undercurrent layer that outer tube can stop the water on the riverbed to flow into interior pipe influences sample effect, manages sulculus in silt stops up in the process that also can prevent from inserting simultaneously.When being inserted into the degree of depth to be measured, outer tube is mentioned, a little more than little troughed belt to be measured, must guard against fully and take out, can cause the water on the riverbed to pour in sampling well when taking out fully.By the sampling pipe that is fixed on different little troughed belts can be more convenient the water sample of in-situ acquisition different depth, simultaneously since the big limit of outer tube prevented the interference of river bed water to institute's water sampling, sample can react the physicochemical property of undercurrent layer water sample preferably.
