Abstract
The utility model relates to a liquid collecting device, in particular to a soil leakage solution extraction device. The device comprises a percolating pipe and a liquid suction pipe and is characterized in that the liquid suction pipe and an air suction pipe are inserted on a bottleneck of a closed solution collecting bottle, wherein the other end of the liquid suction pipe is inserted into the percolating pipe; and the other end of the air suction pipe is connected with a negative-pressure air suction device. In the technical scheme of the utility model, the special percolating pipe is adopted, therefore, the straight leakage water in the soil can automatically flow into the percolating pipe by virtue of the logging-injecting pressure and can be converged at the bottom of the percolating pipe; meanwhile, the negative pressure system is adopted for collecting the soil solution converged at the bottom of the percolating pipe in the collecting bottle in a centralized way, so as to realize various relevant chemical analysis and measurement directly without filtration. The soil leakage solution extraction device has the characteristics of simple and practical structure and larger amount of the collected soil solution.
Description
Technical field
The utility model relates to the liquid acquisition device, particularly soil percolation solution extraction element.
Background technology
The soil liquid and the holard are the important research objects in soil science, plant nutrient and the Research of Environmental Sciences field, and the success of its sample is obtained whole research is had very important significance.Present domestic soil liquid acquisition method only has the scientific research personnel of Nanjing Soil Inst., Chinese Academy of Sciences through exploring, developed the device of the direct extracting soil liquid of a kind of original position, adopt porosint to be made into percolating pipe, by percolating pipe is applied negative pressure, after solution in the soil is filtered by porosint, enter in the percolating pipe, then the solution sucking-off in it.Because above-mentioned porosint is more expensive, and need negative pressure to draw, so just make whole soil liquid collection process very complicated, and soil liquid extraction rate is slower, is difficult to satisfy the test of the bigger index of some demand water sample amounts.
Summary of the invention
It is fast that the purpose of this utility model provides a kind of solution extraction rate, soil percolation solution extraction element easy to use.
For achieving the above object, the technical solution of the utility model is: a kind of soil percolation solution extraction element, comprise percolating pipe and pipette, it is characterized in that on the bottleneck of airtight solution receiving flask, being inserted with pipette and air intake duct, wherein the other end of pipette is inserted in the percolating pipe, and the other end of air intake duct links to each other with negative pressure air-suction device.
Above-mentioned percolating pipe is the pipe of lower end closed, and being made progress by the lower end has the inlet opening on the tube wall of 10-30cm, is wrapped with filter cloth at the perforate position of percolating pipe.
Above-mentioned negative pressure air-suction device is made up of with the vacuum pump that links to each other with surge flask airtight surge flask.
In the technical solution of the utility model, adopted distinctive percolating pipe, make the straight infiltration in the soil flow in the percolating pipe automatically by surveying consolidation pressure, and collect in bottom the percolating pipe, utilize negative pressure system simultaneously, the soil liquid centralized collection that collects in percolating pipe bottom behind receiving flask, just can directly be carried out various relevant chemical analyses, mensuration, need not filtration.It is simple in structure, practical that this device has, and the bigger characteristics of amount of soil liquid collection.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model percolating pipe.
Embodiment
As shown in Figure 1, this device is made up of percolating pipe 5, pipette 6, air intake duct 7, solution receiving flask 4; The structure of percolating pipe 5 as shown in Figure 2, percolating pipe 5 is the pipe of lower end closed, and the uniform inlet opening 5-1 that has on the tube wall about the 20cm of distance lower end enters in the percolating pipe for preventing the particle in the soil, be wrapped with filter cloth 5-2 at the perforate position, filter cloth can adopt nonwoven fabrics.Gather straight infiltration soil depth in the soil during use as required, percolating pipe is placed in the soil, make the position of inlet opening just in time be positioned at the degree of depth that needs, and the upper end that makes percolating pipe bassets about 30, simultaneously an end of pipette 6 is inserted in the bottom of percolating pipe, the other end of pipette is inserted in the solution receiving flask 4.Also be inserted with air intake duct 7 in the solution receiving flask, the other end of air intake duct links to each other with negative pressure air-suction device.Airtight between the outer wall of above-mentioned pipette and air intake duct and the solution receiving flask bottleneck, when the soil liquid in the needs extraction percolating pipe, the negative pressure air-suction device that will link to each other with air intake duct is opened, make and produce negative pressure in the solution receiving flask, the soil liquid of percolating pipe bottom is inhaled in the solution receiving flask by pipette like this.
When needs carry out the sampling of multiple spot, different depth, after air intake duct in a plurality of said apparatus 7 can being concentrated connection, be connected with the air entry 2 of negative pressure air-suction device, above-mentioned negative pressure air-suction device is made up of the interface 1 that links to each other with vacuum pump on airtight surge flask 3 and the surge flask, be connected in interface 1 and air entry 2 and the airtight surge flask, by vacuum pump when taking out negative pressure in the surge flask, just can make a plurality of solution receiving flasks produce negative pressure simultaneously by a surge flask, thereby can take a sample to the liquid in the percolating pipe in a plurality of measurement points, very easy to use.
According to the needs of sampling amount, the distance of inlet opening and percolating pipe lower end can be about 10-30cm on the percolating pipe, and the distance of inlet opening and percolating pipe lower end has determined the water amount in the percolating pipe.
