Description
Technical field
The utility model relates to a kind of mesocosm moisture control device, particularly a kind of device that is applicable to marsh wetland underground water observation, control and cyclic test.
Background technology
Mesocosm had both kept the integrality of natural ecosystems, can control factor of influence easily again, was usually used in Wetland ecological research.Often adopt mesocosm to realize that wetland and bog dissolved organic carbon DOC loss process and WATER LEVEL CHANGES are to bog carbon cycle influence research in the world.The common method to set up of mesocosm is: the bog right cylinder that will be under the freezing state is placed in the adiabatic plastic cylinder, keeps complete vegetation, reduces as far as possible the cylindrical interference of bog.
The mesocosm observation that present domestic field test adopts and control phreatic mode and adopt vertical perforation the in top to insert the mode of permeable hollow PVC plastic tube more is infiltrated the moisture height and is understood and systematically descend height of water level by measuring every day in the pipe.Existing this observation and control the problem that phreatic mode exists and be: underground water is that the underground water of different levels is mobile fully up and down for total system by identification in the permeable hollow PVC plastic tube, diffusion and mixing and completeness infiltrate into the result in the PVC plastic tube, in fact, because underground water flows for a long time and can inevitably cause local the obstruction when infiltrating in the PVC plastic tube, simultaneously, PVC plastic tube hollow, the air pressure deviation of in measuring pipe, ignoring during groundwater depth can cause equally have certain deviation between the ground water elevation of surveying and the actual ground water elevation, can reflect system's groundwater depth exactly thereby can't record; In addition, artificially in the system of each repeated measurement underground water table can not to and in time represent intuitively.
The utility model content
Technical problem underlying to be solved in the utility model is, overcomes institute's ground water elevation of surveying that existing mode exists and the deviation between the actual ground water elevation, reduces in a large number artificially repeated labors.The utility model provides the observation of a kind of mesocosm underground water table, control and circulating device:
It comprises that mesocosm steel drum, water inlet system, row control water system and water storage barrel; Described mesocosm steel drum is wall sealing uncovered stainless steel cask, and the bottom is provided with water delivering orifice; Described water storage barrel is arranged at water delivering orifice one side of mesocosm steel drum, and is connected with the mesocosm steel drum by row's control water system; Described water inlet system is arranged on mesocosm steel drum top.
As previously discussed, illustrate further to, described water inlet system comprises the second water-level observation pipe and water inlet and filter sand pocket;
The second water-level observation pipe is length 35cm diameter 90mm stainless-steel pipe, the perforation of hollow steel tube even tube wall;
It is that dual crocus cloth sweeps along particle diameter to place second water-level observation pipe bottom less than the 4mm sandstone that water inlet filters sand pocket, the second water-level observation pipe outside tube wall dual crocus cloth of steel wire bundle, vertically be put in the set system of mesocosm, require to reserve according to system experimentation and be higher than System planes 5～10cm height.
As previously discussed, illustrate further and control water system into, described row and comprise that water delivering orifice filters sand pocket, high pressure valve, white plastic-aluminum aqueduct, water level control hanging ring and water-level observation chi;
It also is that dual cotton gauze wraps up particle diameter less than the filter bag of 4mm grail that water delivering orifice filters sand pocket, places the high pressure valve homonymy;
But high pressure valve is stainless steel high pressure filter-type ball valve, and described white plastic-aluminum aqueduct is white hard sun power tailored version plastic-aluminum aqueduct, is connected with high pressure valve by water pipe head.
Water level control hanging ring and water-level observation chi all are arranged on the mesocosm steel drum sidewall, and water level control hanging ring is the hollow iron hoop, and the water-level observation chi is the vertical rule of portrayal on mesocosm steel drum sidewall.
As previously discussed, illustrate further into, described water storage barrel is 5L white plastic bucket, and with can airtight water cover.
As previously discussed, illustrate further into, described water storage barrel bung perforation and with white plastic-aluminum aqueduct and is connected junction use glass cement encapsulation process.
Beneficial effect:
The utility model is by connecting the white plastic-aluminum aqueduct that filters sand pocket and pass water level control hanging ring at steel drum water delivering orifice place, utilize the principle of linker, height mesocosm underground water table when white plastic-aluminum aqueduct middle water level is static has and in time presents ground water elevation, advantage such as accurate and directly perceived.

Embodiment
Referring to Fig. 1, at first close the high pressure valve 302 of outlet system, in the water inlet system 2 that mesocosm steel drum 1 top arranges, insert water inlet pipe, moisture is subjected to gravity to filter sand pocket 202 downwards and diffusion all around through water inlet, treat that underground water evenly distributes and just in the second water-level observation pipe, 201 converge when oozing no longer down when reaching a certain height, at this moment, open the high pressure valve 302 of outlet system, equally, the gravitate current begin to be flowed out by water delivering orifice 101, at first process is that water delivering orifice filters sand pocket 301, thereby have various root systems during to Groundwater Flow and soil particle has carried out preliminary filtration, current are through high pressure valve 302 then, filter again by its built-in filter, the material that very easily causes line clogging that contain in the underground water this moment significantly reduces, the current further white plastic-aluminum aqueduct through passing water level control hanging ring 304 303 flow in the water storage barrels 4, the fixed position of controlling hanging ring 304 because of water level is desired underground water table in the mesocosm steel drum 1, utilize law of connected vessels, in case underground water table is too high in the microcosm steel drum 1, underground water will slowly import in the water storage barrel 4, maintain an equal level the height of the maximum height water level control hanging ring 304 when this moment, white plastic-aluminum aqueduct 303 interior current were static until the two water level; Underground water table is low excessively in microcosm steel drum 1, and the level height of current can be read by the water-level observation chi in the white plastic-aluminum aqueduct 303.When water in the water storage barrel 4 is full, but whether just temporary close high pressure valve 302 cuts off current, aquifer yield is measured, and selected to refill in the microcosm steel drum 1 according to testing requirements.So just realized the phreatic timely observation of mesocosm, control and circulation.
By reference to the accompanying drawings embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
