Abstract
The utility model relates to a sediment interstitial water collection device for a laboratory. The device comprises a soil solution sampler and a container which is used for containing sediments, wherein a collection hole is formed in the container; the soil solution sampler comprises a water taking head which is inserted into the container from the collection hole and a plastic pipe which is connected at the rear end of the water taking head, wherein the periphery of a connecting part between the water taking head and the plastic pipe is sleeved with an elastic rubber sleeve; the elastic rubber sleeve is tightly bonded with the inner wall of the collection hole when the water taking head is inserted into the collection hole. During the collection of interstitial water, the periphery of the connecting part between the water taking head and the plastic pipe is sleeved with the elastic rubber sleeve which is inserted into the collection hole and can be tightly bonded with the inner wall of the collection hole, so that the collection hole is completely sealed by the elastic rubber sleeve. Thus, the whole collection device has the good sealing performance, i.e.,, the leakage of the water and the sediments in the container is avoided. Therefore, the clean environment of the laboratory is maintained. The device provided by the utility model is suitable for collecting the sediment interstitial water under laboratory conditions.
Description
Technical field
The utility model relates to the harvester of sediment interstitial water, particularly a kind of use for laboratory sediment interstitial water harvester.
Background technology
Sediment interstitial water is the important parameter of water/sediment interface mass exchange, Interstitial Water in sediment can discharge various nutriments in overlying water, the composition of Interstitial Water increases and constantly changes with the degree of depth, and the material of the different layerings of research Interstitial Water changes the situation of change that can understand whole water environment system.
The device that gathers at present sediment interstitial water is mostly on-the-spot in-situ acquisition far away, heavier, gathers and once can upset afterwards the original structure of sediment, and acquisition range is meticulous not, and the sealing situation of collection sediment interstitial water is very undesirable.Under laboratory condition, collection is obtained sediment interstitial water and can be used Soil moisture sampler, Soil moisture sampler is inserted in the sediment in the container of simulated field environment and just can obtain Interstitial Water, but, between Soil moisture sampler and container, can, because poorly sealed and cause and leak, leak sediment, to laboratory environment, cause destruction.
Utility model content
In order to overcome above-mentioned technical matters, the purpose of this utility model is to provide a kind of use for laboratory sediment interstitial water harvester, and this device can Quick Acquisition Interstitial Water under laboratory condition, and device sealing, can not cause Lou water and sediment seepage.
The technical scheme that the utility model adopts is:
A kind of use for laboratory sediment interstitial water harvester, comprise Soil moisture sampler and for placing sedimental container, described container is provided with and gathers hole, described Soil moisture sampler comprises the plastic tube that inserts the water intake in container and be connected to water intake rear end from gathering hole, the periphery of described water intake and plastic tube junction is arranged with elastic rubber sleeve, described water intake inserts while gathering hole, and elastic rubber sleeve fits tightly with collection hole inwall.
As the further improvement of technique scheme, described elastic rubber sleeve be length range at the rubber tube of 7-9mm, and the length that is sheathed on the rubber tube pipeline section of water intake and plastic tube periphery is all no less than 3mm.
As the further improvement of technique scheme, the tail end of described plastic tube is provided with collecting unit.
As the further improvement of technique scheme, described collecting unit comprises vacuum test tube and is connected to the injection needle on plastic tube, and the needle point of described injection needle front end inserts from the oral area of vacuum test tube.
The beneficial effects of the utility model are: when gathering Interstitial Water, the elastic rubber sleeve that utilization is set in water intake and plastic tube junction periphery inserts collection hole, make it and gather hole inwall and fit tightly, thereby reach with elastic rubber sleeve and will gather the complete totally enclosed object in hole, make the favorable sealing property of whole harvester, can there is not seepage in the water and sediment in container, kept the environment that laboratory is clean.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram of A part in Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of use for laboratory sediment interstitial water harvester, comprises Soil moisture sampler and for placing sedimental container 1, container 1 is provided with collection hole 2 near the position of bottom.Container 1 is mainly used in simulating sedimental site environment, and sediment is equipped with in its underpart, and sedimental top is overlying water.Soil moisture sampler comprises water intake 3 and plastic tube 4.The diameter of water intake 3 is 2mm, and its pore footpath is 1.5 μ m, and when gathering Interstitial Water, water intake 3 inserts sediment from gathering hole 2.The rear end of water intake 3 is connected to plastic tube 4, and the tail end of plastic tube 4 is provided with collecting unit.
In the present embodiment, collecting unit comprises vacuum test tube 6 and is connected to the injection needle 7 on plastic tube 4, and this injection needle 7 is the supporting syringe needle of common injection needles cylinder.The needle point of injection needle 7 front ends inserts from the oral area of vacuum test tube 6, utilizes negative pressure to gather Interstitial Water.
In order to guarantee that water intake 3 inserts the rear water and sediment of container 1 and can not reveal from gathering hole 2, the sheathed elastic rubber sleeve 5 of periphery at water intake 3 with plastic tube 4 junctions, after elastic rubber sleeve 5 is inserted in, its slightly larger in diameter is in the diameter that gathers hole 2.Water intake 3 inserts while gathering hole 2, elastic rubber sleeve 5 is screwed in and gather hole 2 and fit tightly with gathering hole 2 inwalls, utilizes the elastic deformation sealing of elastic rubber sleeve 5 to gather hole 2, as shown in Figure 2.
In the present embodiment, the rubber tube that elastic rubber sleeve 5 is 7-9mm, and the length that is sheathed on the rubber tube pipeline section of water intake 3 and plastic tube 4 peripheries is all no less than 3mm.The rubber tube pipeline section that is sheathed on water intake 3 peripheries is between rubber tube and water intake 3, plastic tube 4, to produce enough large friction force in order to guarantee, while preventing elastic rubber sleeve 5 screw-in, relative displacements occur elastic rubber sleeve 5.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
