Description
Technical field
The utility model relates to a kind of experimental provision, particularly a kind of green damp enclosure experimental provision.
Background technology
Green tide is a kind of harmful algal bloom generally occurring in world coastwise contries, is also a kind of ecological anomaly that can cause secondary environment harm simultaneously.All there is fairly large green tide in many coastal states, and is difficult to so far control, becomes global problem.Since two thousand seven, extensive green tide is broken out in continuous 6 years in China's Huanghai Sea offshore sea waters, and maximum relates to area and reaches 60000km
2, accumulation area coverage reaches 2700km
2, green damp area big and form can be rated as soon the first in the world, the littoral marine eco-environment and Ecosystem Service are caused to generation heavy damage, cause tremendous economic loss.For the extensive green tide of China's Huanghai Sea, break out, home and abroad all goes into overdrive to study, even employed satellite remote sensing tracking, because the green tide of China's Huanghai Sea breaks out suddenly and break out background more complicated, part scientist has proposed some deductions and hypothesis, but the green tide of China's Huanghai Sea breaks out source and outbreak mechanism is also not fully aware of, the difficult point place of the green damp present Research of Zhe Yeshi China so far.
Seawater eutrophication, the unique biological property of green damp algae self, Ecological Suitability are that green tide breaks out three important elements.The green damp algae propagation characteristic of more concerns both at home and abroad at present and growth conditions, and enclosure experiment is also method conventional in research process, experimental technique is roughly: device and assembly thereof are transported to green tide and break out sea area, by experimenter, device is assembled, before adding green damp algae, first green damp algae weight in wet base and physiological factor are measured, be added to after device, then routine observation and mensuration.
Current experimental provision used or inside and outside water body is separated, otherwise gauze aperture is too large, and green damp algae is spilt, and the result that experiment obtains still can not be broken out the upgrowth situation of the green damp algae in sea area by the green tide of complete reaction; And this experimental provision is commonly expensive large-scale experimental device, experiment field condition is required high, and operation on the sea has certain risk.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of green damp enclosure experimental provision, and this device can better be simulated the actual environment that green tide breaks out marine site, and its cost is low, easy to assembly.
The utility model is achieved through the following technical solutions:
A green damp enclosure experimental provision, comprises tank and algae bucket; The top of described tank is provided with water inlet, and the sidewall of close bottom is provided with delivery port; The opening part of described algae bucket is provided with pore gauze cover, and described pore gauze Zhao center is provided with opening; The delivery port of described tank is connected with one end of water pipe, and the other end of described water pipe is placed in the top of pore gauze cover opening; On described water pipe, be also provided with flow control valve.
Wherein, described pore gauze cover comprises that the framework of falling funnel type and aperture are the transparent screen cloth of 20 object, and described framework is made with hard material, and its upper shed is little, and under shed is large, and described transparent screen cloth is fixed on described framework.
Wherein, described tank is placed on the chopping board higher than algae bucket.
Wherein, described water pipe is the Multi-head water pipe that has two outlet pipes at least, and each outlet pipe is provided with flow control valve.
Wherein, described tank is that capacity is the vinyon bucket of 1000 liters.
Wherein, the vinyon box that described algae bucket body is the high 70cm of being respectively of length and width, 40cm, 50cm.
This device also comprises water storage box, and described water storage box is connected with the water inlet of tank with water pipe by water pump.
The beneficial effects of the utility model are:
1) condition of culture breaks out the actual environment in marine site closer to green tide, can provide strong data supporting for disclosing the aspects such as green damp outbreak mechanism;
2) realize the parallel laboratory test of many groups, make experimental data more according to convincingness;
3) experiment material easily obtains, and cost is low, and experimental provision can be assembled, convenient in carrying and can repeating
Utilize, cost performance is high;
4) utilize flow-control valve regulation water velocity to simulate marine hydrodynamics circulating;
5) opening part of algae bucket is provided with the pore gauze cover that transparent network cloth is made, and stops that green tide overflows with current, guarantees that experimental data is true and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-tank, 2-algae bucket, 3-pore gauze cover, 4-water pipe, 5-chopping board, 6-water storage box.
Embodiment
Below in conjunction with specific embodiments and the drawings, further set forth the utility model.
As shown in Figure 1, a kind of green damp enclosure experimental provision, comprise tank 1, algae bucket 2 and water storage box 6, the top of tank 1 is provided with water inlet, sidewall near bottom is provided with delivery port, water storage box 6 is connected with the water inlet of tank 1 with water pipe by water pump, the opening part of algae bucket 2 is provided with pore gauze cover 3, this pore gauze cover 3 comprises that the framework of falling funnel type and aperture are the transparent screen cloth of 20 object, the framework of falling funnel type is made with hard material, its upper shed is little, under shed is large, transparent screen cloth is fixed on the framework of falling funnel type, one end of the delivery port water receiving pipe 4 of tank 1, the other end of water pipe 4 is placed in the opening part of pore gauze cover 3, water pipe 4 is provided with flow control valve.
