Embodiment
Below in conjunction with embodiment and comparative example, technical scheme of the present invention is described further, but should not be construed as limitation of the present invention:
embodiment 1
Fig. 1 is structural representation of the present invention, Fig. 2 is supporting pipe elevational schematic of the present invention, Fig. 3 is the cross-sectional schematic diagram of supporting pipe of the present invention, Fig. 4 is slip intake pipe partial schematic diagram of the present invention, composition graphs 1, Fig. 2, Fig. 3, shown in Fig. 4, water body hierarchical synchronization sampling aut.eq., this device comprises supporting pipe 1, slip intake pipe 2, connecting pipe 3, sampling bottle 5 and vacuum pump 7, wherein, mark on graduated supporting pipe 1 and longitudinally have strip crevice, make water body freely can enter into supporting pipe inner, supporting pipe material is stainless steel thin-wall pipe.Slip intake pipe 2 is multiple, and each slip intake pipe 2 one end to be stuck in strip crevice by slide block and can to slide up and down, and the other end is connected with sampling bottle 5 lower water inlet respectively by connecting pipe 3, gas outlet, sampling bottle 5 top connection vacuum pump 7.Slip intake pipe is organic glass pipe, is adjusted and fix the position of slip intake pipe by slide block, thus controls sampling depth.Sampling bottle is for collecting each layer water sample, and the air in sampling bottle is extracted in the effect of vacuum pump out, is convenient to water sample and flows into.Because variant deep slip intake pipe is connected to each sampling bottle respectively, make water body each layer sampling process synchronous.
In order to prevent water sample from refluxing, described connecting pipe 3 is provided with tongs 4.
Owing to having multiple to the sampling bottle of water body stratified sampling, conveniently multiple sampling bottle is connected with vacuum pump, and described sampling bottle 5 is connected with vacuum pump 7 by four-way piece 6.
In order to be fixed supporting pipe, bottom described supporting pipe 1, base is housed, base bottom is equipped with rivet, is convenient to supporting pipe fixing in water body.
embodiment 2
Adopt a method of sampling for water body hierarchical synchronization sampling aut.eq., the method comprises the following steps:
(1) water surface scale is read by supporting pipe 1;
(2) take out supporting pipe 1, regulate the position of slip intake pipe 2 with the degree of depth of corresponding stratified pumping;
(3) open tongs 4 and vacuum pump 7, realize each water layer synchronized sampling to sampling bottle 5;
(4) sampling terminates rear tongs 4 and clamps connecting pipe 3.
comparative example
CN101446525A discloses a kind of hand-operated stratified fixed-depth water sampler, although can gather different depth water sample, repeatability is high, and can not hierarchical synchronization sample, repetitive operation easily causes disturbance to water body, and sampling efficiency is also lower.And this device can hierarchical synchronization be sampled, do not need repeatedly repetitive operation, can well solve the problem.
A kind of stratified sampler of water samples disclosed in CN101551304A, different water levels water sample can be gathered, but each sampling bottle is all positioned at below the water surface, the synchronized sampling of each sampling bottle more difficult control during operation, and be difficult to obtain the following certain depth water sample of the water surface, after terminating owing to sampling, sampling bottle will take out water body, and one time sampling volume is less.Water body hierarchical synchronization sampling aut.eq. of the present invention and the method for sampling overcome the problem of existing hydrophore, realize water body hierarchical synchronization efficient sampling, simultaneously owing to adopting vacuum pump suction, each sampling bottle is made to be positioned at more than the water surface, synchronism is good, and hold slip intake pipe due to supporting pipe and connecting pipe enters in water body, and little to water body interference, be convenient to carry out hierarchical synchronization sampling to water body.
To sum up, this device synchronously can carry out efficient sampling automatically to each water layer, meets the water quality environment monitoring sample requirement of different water body, overcomes existing water body sampling device synchronism poor, large to the disturbance of water body, is difficult to the problem gathering original position water sample.
