The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of paddy soil moisture extraction element, the intake pipe that comprises water intaking bottle and PVC material, the bottom of described intake pipe is provided with and stores layer, described storage floor top is provided with infiltration district, described infiltration district comprises the filtering layer that is arranged on a plurality of water seepage holes on water intaking tube wall and is wrapped in intake pipe outer wall water seepage hole place, described intake pipe upper end open and by the first seal cap sealing, described the first gland bonnet be provided with and the first gland bonnet between the suction hose and the first vacuum-pumping tube that are tightly connected, one end of described the first vacuum-pumping tube is arranged in intake pipe, described water intaking bottle opening is provided with the second seal cap sealing, described the second gland bonnet be provided with and the second gland bonnet between the water inlet pipe and the second vacuum-pumping tube that are tightly connected, one end of described the second vacuum-pumping tube is arranged in water intaking bottle, one end of described suction hose is arranged on and stores in layer, the other end is connected with described water inlet pipe.
Described filtering layer is that multilayer 400 object nylon wires form.
The described height that stores layer is 3~5cm.
Described infiltration district height is 5~10cm.
The diameter of described water seepage hole is 0.5mm, and described water seepage hole tightens solid matter cloth at the water intaking tube wall in described infiltration district.
Adopted the following advantage of the utlity model has of technique scheme:
1, PVC intake pipe is imbedded soil layer, PVC intake pipe can be made the model of multiple height, in order to extract the percolating water of different depth soil layer (0-150cm), accomplish accurately to sample targetedly, when getting percolating water, utilize vacuum draw principle, make the water in intake pipe flow into water intaking bottle, can not take out intake pipe sampling, thereby facilitate sampling operation.
2, on the tube wall of PVC intake pipe bottom, bored many apertures as water seepage hole, like this, can fully guarantee that after placing into the soil, the inside and outside moisture of PVC intake pipe exchanges with heat, plant growth has been down to bottom line impact.
3, the filtering layer that water seepage hole is also enclosed with outward, the Main Function of filtering layer is isolation larger particles, guarantees sampling evenly, hole is not blocked.
4, lightweight, the impact that is not subject to moisture and soil acidity or alkalinity of pvc pipe, does not need any preservative treatment during laying, manpower is required lower, is easy to the sampling operation of wetlands ecosystems.
5, pvc pipe end sealing lid, before water intaking, 4h is evacuated intake pipe, treats that water infiltrates in pipe after 4h, utilizes negative pressure method by holard suction water intaking bottle, and the environmental baseline that makes to fetch water is consistent, has guaranteed sampling precision.
In sum, the utility model adopts that PVC intake pipe has good tension, compressive strength, corrosion resistance, good watertightness, anti-ly gnaws, the lightweight and little feature of volume, is applicable to the soil moisture extraction element in rice field.In addition, the utility model is for the singularity of water paddy soil water, and intake pipe overground part is produced peak level higher than rice field, and the soil sampling district of intake pipe bottom insertion simultaneously part is evenly holed, can guarantee that so the inside and outside moisture of intake pipe exchanges with heat, makes observed result more representative.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1, a kind of paddy soil moisture extraction element, comprises
One PVC intake pipe, diameter 5cm, the storage layer of 3~5cm is arranged at the bottom of intake pipe 1, store layer and be used for preserving solution, on it, the length of 5~10cm forms infiltration district 13, approximately 300, the hole that infiltration district 13 comprises diameter 0.5mm, infiltration district 13 external application filtering layer 14 parcels, filtering layer 14 is 4 layers of nylon wire parcel of approximately 400 screen clothes, and filtering layer 14 also can replace with bolting silk or pot clay end, and intake pipe 1 cleans with diluted acid before use.During use, intake pipe 1 on the ground part exceeds top layer, rice field 30~60cm, the first gland bonnet 11 sealings for top, the first gland bonnet 11 is silica gel sealing lid, on the first gland bonnet 11, be drilled with two holes, suction hose 12 is inserted in one of them hole, and the end of suction hose 12 is concordant with the bottom in infiltration district 13, in another hole, insert the first vacuum-pumping tube 3, the first vacuum-pumping tubes 3 at intake pipe 1 from the about 6~10cm of the first gland bonnet 11.The first gland bonnet 11 and suction hose 12, the first vacuum-pumping tube 3, intake pipe 1 all with sealing strip sealing, are guaranteed good airproof performance with gland bonnet contact position.
