Abstract
The invention discloses a test measuring cylinder device capable of simulating groundwater level variation influences. The test measuring cylinder device is characterized by comprising a measuring cylinder, an observation pipe, a water storage tank, a foam maker, a blow-off pipe, a rubber pipe, a first switch, a second switch, a fixing hoop and a third switch. The observation pipe is fixed to and communicated with the measuring cylinder, the measuring cylinder is communicated with the water storage tank through the rubber pipe, and the blow-off pipe is arranged at the bottom of the measuring cylinder; the foam maker is fixed to the water storage tank through the fixing hoop and communicated with the water storage tank through the rubber pipe; the first switch, the second switch and the third switch are arranged at an outlet of the water storage tank, the end of the observation pipe and an opening of the blow-off pipe respectively. According to the test measuring cylinder device, a communicating vessel is actually formed through the foam maker, the water storage tank and the measuring cylinder, then the position height of the foam maker determines the water level in the measuring cylinder, and thus the amount of supply water needed for irrigation can be known.
Description
Technical field
The present invention relates to a kind of test and surveys cartridge, concretely relate to a kind of can the examination of simulated groundwater fluctuation of water table
Test cartridge.
Background technology
Along with widespread pollution from the overuse of fertilizers and pesticides in rural area preventing and treating is increasingly paid attention to by people, to the basic scientific research of farmland nitrogen and phosphorus loss also the deepest
Entering, rainfall also obtains many achievements to the influence research of the elements such as nitrogen phosphorus in agricultural land soil.But Study of The Underground water water level becomes
Moving goes back seldom to Nitrogen In Soils P elements Transport, and particularly higher at south groundwater level, crop is tight by stain evil
The area of weight, subsoil water high water level frequently changes the impact utilizing the conversion of nitrogen phosphorus transfer and Crop and also rarely has research.
Meanwhile, how to facilitate the situation simulating the variation of subsoil water high water level accurately, how particularly water level can reach accurately
To the water level of a certain setting, become the key factor of impact test.
The research in the past having, has plenty of by toward surveying pouring in cylinder, improving groundwater level by infiltrating, or uses height
The outlet that pressure passes water through bottom survey cylinder supplements, and these methods all will be through the just meeting of seepage flow after a while due to water
Arrive, therefore can not determine, at the initial stage of pouring water, the water yield required supplementation with, be easily caused situation about filling or fill less more and occur, take
Time laborious, and precision is the highest.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides one to become by simulated groundwater water level
Cartridge is surveyed in the test of dynamic impact.
Technical scheme: for solve above-mentioned technical problem, the present invention provide a kind of can simulated groundwater fluctuation of water table impact
Cartridge is surveyed in test, including survey cylinder, sighting tube, storage tank, foam maker, adjutage, rubber tube, the first switch, the
Two switches, clips, the 3rd switch, described sighting tube is fixed with surveying cylinder and connects, and surveys cylinder and passes through rubber tube with storage tank
Connection, described adjutage is located at bottom survey cylinder；Described foam maker is fixed on storage tank by clips and passes through rubber tube
Connect with storage tank；Described first switch, second switch and the 3rd switch are respectively provided at storage tank exit, observation pipe end
Portion and water discharging spout.
Further, described clips is fixed by fixed screw, it is preferable that described fixed screw is butterfly screws.
Foam maker is the effect of air inlet, and outside air enters storage tank by foam maker.
Further, described storage tank top is provided with water storage case lid.
Further, described sighting tube is fixed by support.
Beneficial effect: the present invention possesses advantages below in terms of existing technologies:
After apparatus of the present invention connection, by adjusting the position of foam maker, open the first switch, second switch, closedown the 3rd
Switch, can make the water in storage tank add to survey in cylinder by law of connected vessels, and the water level surveyed in cylinder eventually arrives
Reach the position with foam maker, simple to operate, time saving and energy saving.Due to storage tank with survey cylinder be to be connected by rubber tube, removable
Unload, it is possible to convenient operation current are from surveying the test that cylinder 1 top is infiltrated.
Additionally, in substance form a linker by foam maker and storage tank with survey cylinder, therefore the position of foam maker is high
Degree determines survey cylinder middle water level height such that it is able to learn the rate of water make-up needing to irrigate.
Accompanying drawing explanation
Fig. 1 be the present invention a kind of can simulated groundwater fluctuation of water table impact test survey cartridge structural representation.
Fig. 2 is that the present invention is a kind of testing of simulated groundwater fluctuation of water table impact can survey the structural representation of clips in cartridge
Figure.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
Shown in Fig. 1 a kind of can simulated groundwater fluctuation of water table impact test survey cartridge, by survey cylinder 1, sighting tube 2,
Storage tank 3, foam maker 4, adjutage 5, rubber tube 6, support 7, switch 8, switch 9, water storage case lid 10, solid
Surely bind round 11, switch 13 compositions.Survey cylinder 1 to connect with sighting tube 2 and adjutage 5, storage tank 3 by rubber tube 6 and
Sighting tube 2 other end connects, and foam maker 4 is connected with storage tank 3 by rubber tube 6, and is fixed to by clips 11
On storage tank 3, at the adjutage 5 of storage tank 3 outlet, sighting tube 2 other end and survey cylinder 1, set first respectively open
Pass 8, second switch the 9, the 3rd switch 13.
Fig. 2 is that the present embodiment is a kind of the test of simulated groundwater fluctuation of water table impact can be surveyed the structure of clips in cartridge and shows
It is intended to, is made up of clips 11 and fixed screw 12；The preferred butterfly screws of fixed screw 12, facilitates hand operation.
Foam maker 4 is placed in clips 11 one end, by adjusting the position of clips 11, makes foam maker 4 arrive the water level set
Highly, fixed by fixed screw 12.
When needs simulated groundwater water level rises to a certain height, water can be filled in storage tank 3, after noting filling
Tighten water storage case lid 10, prevent from producing aeration accuracy in linker.By foam maker 4 being fixed on and surveying cylinder
Water level equal-height position set by 1, opens the first switch 8, second switch 9, closes the 3rd switch 13.Pass through linker
Principle, can make to survey the water level in cylinder 1 and sighting tube 2 and all can reach foam maker 4 height and position, close the first switch 8,
Second switch 9.When simulated groundwater water level reduces, foam maker 4 position can be reduced, open the first switch 8,
Two switches 9 get final product lowering of watertable.If needing sampling, then can pass through intake 5, opening the 3rd switch 13 and fetching water.
Owing to storage tank 3 is attached, therefore when needs simulated rainfall or irrigation by connection rubber tube 6 with surveying cylinder 1
During situation, second switch 9 can be closed, and rubber tube 6 is extracted, raise storage tank 3, rubber tube 6 is put into survey cylinder 1
Upper place, opens the first switch 8, adjusts foam maker 4 position, can realize the situation of rainfall or irrigation, infiltrate etc.
Test.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for those skilled in the art
For, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications are also
Should be regarded as protection scope of the present invention.
