Present offshore waters or the enclosed seawater pond semiclosed enclosure device that ecological study adopts that experimentizes, constitute support with timber and blue or green bamboo, with plastic-coated high density polyethylene (HDPE) woven cloth is the water proof material, with its encirclement and be fixed on the support, form a semiclosed enclosure, but the spatial variations of flexible material parcel is big, produces drift along with the variation of current and wind, therefore, the water body consumption that can not meticulous control be comprised in each experiment enclosure; In addition, under guiding such as current, wind, be easy to generate the phenomenon of local displacement, the stability of influence bottom environment can not be carried out experimental implementation smoothly; In the water body of semiclosed enclosure device, the gas exchange rate variance of atmosphere and water body is unfavorable for cultivating biological normal growth, thereby makes pilot office be limited to the research that comprises water body in the enclosure, can not carry out the research at the ecosystem or food chain; And can't solve and change water problems and cleaning problem in experiment and the running.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can be in offshore waters or enclosed seawater pond when experimentizing ecological study, the water body consumption that is comprised in each experiment enclosure of the meticulous control of energy, guarantee the stability of bottom environment, experimental implementation can be carried out smoothly, research be can carry out, and the semi-closed barricading device and the using method thereof of changing the water problems and the problem of cleaning in experiment and the running solved smoothly at the ecosystem or food chain.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of semi-closed barricading device, comprise semiclosed enclosure, described semiclosed enclosure adopts plastic plate to surround semi-enclosed polyhedral structure, top at described semiclosed enclosure is provided with the operating platform that is made of plastic plate, on described operating platform, be provided with and detect sample adding device and stir gas charging system, establish the replacing water device at the middle hypomere of described semiclosed enclosure.
Described polyhedral structure is triangle, square or hexagon.
Described stirring gas charging system comprises connecting axle, gas exhausting stone and breather pipe.
The described water device that changes is apart from bottom 10-20 centimetre.
Put the imbedded and perched shellfish in a suitable place to breed in the test of the bottom of described semiclosed enclosure device, the centre of described semiclosed enclosure is a water body, in described water body, cultivate the bait plankton of shellfish, described semiclosed enclosure top is operating platform, carry out the detection and the regulation and control of water body at described operating platform, the research experiment ecological law when experiment beginning and end, is opened or is closed the described water device that changes and advance water and draining.
Compared with prior art, the invention has the advantages that: owing to adopt plastic plate to connect into triangle, square or hexagonal polyhedral structure, each plate is closely arranged each other, make semi-closed barricading device can not produce drift along with the variation of current and wind, can overcome under guiding such as current, wind, the local displacement phenomenon that produces, therefore in offshore waters or enclosed seawater pond when experimentizing ecological study, the water body consumption that is comprised in each experiment enclosure of the meticulous control of energy, guarantee the stability of bottom environment, experimental implementation is carried out smoothly; Owing in semiclosed enclosure device, the stirring gas charging system is set, overcome the problem of atmosphere and water body gas exchange rate variance in the semiclosed enclosure device, help cultivating the normal growth of biology, can carry out research at the ecosystem or food chain; Owing to be provided with in the middle and lower part of semiclosed enclosure device and change the water device, solved and changed water problems and cleaning problem in experiment and the running.
Description of drawings
Fig. 1 is semiclosed enclosure device schematic diagram.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
1, the structure of semi-closed barricading device:
At first, the employing material is PVC, thickness is 10 millimeters, structure and specification is 1 square metre a square plastic plate, with 5 millimeters plastic welding rods, under the high temperature of plastic welding gun, 4 plastic plates are welded to each other the semiclosed enclosure 1 of squarely structure, each plastic plate takes " yi word pattern " closely to arrange each other, forms semi-closed structure; Inwardly inlay width on the top of semiclosed enclosure 1 and be 10 centimetres, thickness and be 10 millimeters PVC plastic plate, be welded to each other with plastic welding rod and form operating platform 2; 30 centimetres of argillo arenaceous are inserted in semiclosed enclosure 1 bottom that forms.
Then, opening an aperture in distance semiclosed enclosure 1 bottom 20 centimeters is 10 millimeters circular hole, installs at tapping and changes water device 3.
Then, in semiclosed enclosure device, place gas exhausting stone 5, gas exhausting stone 5 is placed on the bottom of semiclosed enclosure device 1, require 1 gas exhausting stone 5 of each square metre placement, be communicated with air pump by breather pipe 6, and inflation is started from the bottom, forms inflation stirring system 4, is connected and fixed by connecting axle 7 and operating platform 2.
At last, installation and measuring sample adding device 8 on operating platform detects sample adding device 8 by the pmma material preparation, is placed on the place, angle of operating platform 2, and injection port is positioned at operating platform 2 and underwater.
2, semiclosed enclosure device using method:
The bottom of above-mentioned semiclosed enclosure device 1 is absorbed in argillo arenaceous, the bottom that forms can be tested and be put the imbedded and perched shellfish in a suitable place to breed, semiclosed enclosure 1 part broad in the middle is a water body, cultivate plankton, as the bait of shellfish, top is operating platform 2, carry out the detection and the regulation and control of water body, the material that adds nutritional factors or suppress to grow is regulated and control planktonic kind and biomass, the research experiment ecological law.
When experiment beginning and end, open or close the switch that is positioned at above-mentioned semiclosed enclosure bottom of device, can independently advance water and draining, at corner's mark height of semiclosed enclosure device, to determine water level.
Place gas exhausting stone 5 in semiclosed enclosure device, gas exhausting stone 5 is placed on the bottom of enclosure, is communicated with air pump, stir and inflate, and inflation is to start from the bottom, the process that has longer air water to mix mutually, mixing effective.In experimentation, take corresponding the stirring and inflation according to planktonic biomass, in one day, stir with inflation usually at noon during high-temperature time section 11-14, morning is during 3-6, stir every day and inflation 6 hours, by stirring and inflation, improve the dissolved oxygen levels of water body, stir with the degree of inflation and exceed with the as seen tangible wave of water surface, perhaps adopt the dissolved oxygen of directly measuring water body, general requirement reaches 4 mg/ml.
In experimentation, extract the water sample of different water layers at any time, detect plankton kind and biomass in the water body; Add formula nutritional salt such as nitrogen, phosphorus and silicon, the regulation and control plankton is formed by population; Extract the shellfish of bottom, determine upgrowth situation.According to the proportion of nutrient solution and natural water, determine the method for application of sample, if the proportion of nutrient solution greater than the proportion of natural water, can be added in the surface of natural water,, in whole water body, evenly distribute by natural diffusion; If the proportion of nutrient solution less than the proportion of natural water, can be added in the bottom of natural water,, in whole water body, also can evenly distribute by natural diffusion.
