Description
Technical field
The utility model relates to environmental protection tests and scientific research apparatus field, relates in particular to a kind of water sample acquisition device that is applicable to the surface water bodies such as river, lake and reservoir.
Background technology
Water sampling is basis and the key link in the work such as water quality investigation, water quality monitoring, polluted-water improvement, and the standardization of acquisition operations and the data obtained whether accurate directly affects normally carrying out of follow-up work.
In water body, the difference of the depth of water can cause the difference of each layer of water body character.In same water body, the physical propertys such as the intensity of illumination under different water depth, water temperature, transparency are different; The biochemical indicators such as dissolved oxygen content, micro organism quantity and kind, dissolved organic matter kind also present different; In polluted-water, concentration and the form of some pollutant change along with the variation of the depth of water.The water quality condition of investigation different depth, the material of analyzing each layer of water body form, the form of research material and the Transport And Transformation rule of content between each layer of water body etc. have proposed high requirement to the accuracy of hydrophore and standardization.
At present, lake, the river hydrophore of Environmental Protection in China mechanism and librarian use is of a great variety, and by operation complexity, lake, most river hydrophore can be divided into two classes, and simple type hydrophore and mechanical type hydrophore, be partly seldom intelligent hydrophore.Although simple type hydrophore uses simply, cost of manufacture is lower, the sampling error of himself is larger, and accuracy is difficult to ensure card, and the water sample of collection does not have particular representative; Mechanical type hydrophore is improved compared with simple type at aspects such as adopting the sealing of water receptacle, sampling at set depth, and sampling error is lower, but still exists some component of machine installation complexity, complex operation, device to carry the problems such as inconvenience; Intelligent hydrophore is used for the long-term ocean weather station observation of water body, and sampling acquired results precision is very high, but the support equipments such as it is produced and maintenance cost is expensive, equipment itself and electric power supply carry inconvenience, is more difficultly applied to that field is mobile samples.
At present the domestic hydrophore with synchronous depthkeeping stratified sampling function is few.Once a kind of water sample acquisition device of utility model (license number: CN202599716 U) of the people such as Fu Huifang, this device has the function of depthkeeping and stratified sampling, but adopt water receptacle, in the position on connecting pipe, fix, can not set and adopt the water receptacle degree of depth of living according to actual demand; And in this device, each is adopted water receptacle and is connected by hollow connecting pipe, is interconnected, the water sample in container easily mixes; Moreover, because communicating pipe is stereoplasm tube and can not shrinking, carry inconvenience.Utilize this device to gather water sample, not only can not set the position of adopting water receptacle according to actual needs, and the water sample of respectively adopting in water receptacle is easily mixed.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of synchronously depthkeeping to gather the hydrophore of multilayer water sample, the utility model assembly and disassembly are simple, easy to carry, operation is easily gone, the water sample of different depth under can the same section of synchronous acquisition, in adopting water process, stability is high, closed performance good, systematic error is less.
The purpose of this utility model is achieved through the following technical solutions: a kind of synchronously depthkeeping gathers the hydrophore of multilayer water sample, and it comprises: handle, reel, rope, load-bearing band, buoyancy aid, adopt water unit and great trust, wherein, described handle is fixedly connected with reel, and load-bearing band head end connects reel, removably connects successively from top to bottom buoyancy aid and some water units of adopting, and tail end connects great trust, on load-bearing band, there is scale and a plurality of fixed orifice, adopt water unit by cross pipe support, sampling bottle, ball and cork form, cross pipe support is fixed on load-bearing band, two closure of openings in its horizontal direction, two openings in vertical direction open wide, two sampling bottles respectively screw thread are screwed on two openings of the horizontal both wings of cross pipe support, sampling bottle top bottleneck is water inlet, end bottleneck is water delivering orifice, each sampling bottle is built-in with a ball, the diameter of ball is not less than the internal diameter of the water inlet of sampling bottle, cork is filled in the opening of cross pipe support vertical direction, the diameter of cork is not less than the internal diameter of pipe, the length of cork equals the vertical height of cross pipe support, all corks of adopting water unit connect and compose rope by short rope successively, rope head end is fixed on handle.
Water sampling device is mainly subject to great trust Action of Gravity Field that device is sunk, and the suffered buoyancy of buoyancy aid makes device floating.After the stable no longer sinking of device, upwards lift cord, cork is drawn out the cross pipe support of adopting water unit, water starts to inject in sampling bottle, light plastic ball is along with the water surface in sampling bottle rises gradually near sampling bottle top mouthful, sampling bottle is full of after water, and light plastic ball is blocked sampling bottle top mouthful just, and now water inlet is closed by light plastic ball sealing.In whole sampling process, the suffered buoyancy of whole device is greater than suffered gravity, and buoyancy aid can be bubbled through the water column always.Lift load-bearing band, whole hydrophore is drawn out the water surface, and in sampling bottle, water sample is required water sample, and the water sample degree of depth is buoyancy aid and adopt water unit fixing difference of scale on load-bearing band.
The beneficial effects of the utility model are:
1, water sample that can the same vertical profile different depth of synchronous acquisition water body.
2, intending collection water sample number and sampling depth all can adjust as required.
3, device can guarantee good sealing property in the process that enters water, water inlet, water outlet.
4, buoyancy aid can freely be inflated (venting).
5, each member can be realized quick on-the-spot installation and removal, easy to carry during field operation.
