Description

The artificial upwelling of Self Adaptive Control gushes riser
Technical field
The invention belongs to Yu Haiyang equipment technology and Ocean Fishery Field, the artificial upwelling that relates to a kind of Self Adaptive Control gushes riser.
Background technology
Nature upwelling is a crucial Ocean physical process, it can take the deep sea water that is rich in nutritive salt at the middle and upper levels to, make Upwelling Region become the higher region of fecundity of the sea in the world, can improve fishery production so on the one hand, can improve on the other hand the marine eco-environment.
Artificial upwelling is a kind of earth engineering method, utilizes some devices by lower deep layer temperature and contain rich eutrophic deep sea water and be promoted to surface, upper strata is contained compared with the area of Low nutrients and supplemented, and forms the exchange of the upper and lower water.The fishing capacity that China's fishery is at present powerful and limited operation fishing ground, the contradiction between fragile resource base is becoming increasingly acute, and causes China's marine fishery resources slump of disastrous proportions, immediate offshore area deterioration of the ecological environment intensifying trend.The method of using artificial upwelling is improved the ecotope of shoal of fish self-sow, expands fishing ground scope, forms new fishing ground and becomes an important means.
The nutritive salt in marine site is the indispensable nutrition of phytoplankton and fish growth, and the key that therefore seawater fish increases production is naturally to improve the environmental condition of seawater fish food chain, focuses on supplementing of euphotic layer maritime interior waters nutrient component.In the euphotic layer of ocean, there are phytoplankton growth and breeding, they constantly absorb nutritive salt, and especially at neritic zone, during due to summer, the Growth and Reproduction of phytoplankton is vigorous, makes the nutritive salt approach exhaustion in superficial water; And under the euphotic layer of ocean, nutrient concentrations increases sharply with the degree of depth.If nutritive salt can be gushed and rise to the place that marine superstructure light can arrive by seawater, make plankton volume increase through photosynthesis, as other halobiontic food, this marine site has just become halobiontic fertile soil.
Based on artificial upwelling in transformation the important meaning aspect marine ecology, artificial upwelling becomes focus and the forward position of domestic and international scientific research of seas, but how the nutritious deep sea water promoting is stabilized in to thermocline, be unlikely to because density is deposited to below euphotic layer greatly and very soon, and then lose the meaning that promotes plankton breeding, domestic is still blank to the research of this problem.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide the artificial upwelling of Self Adaptive Control to gush riser.The present invention is gushed the degree of depth of riser apart from sea by automatic adjusting, the deep sea water that makes to promote mixes with surface seawater and is stabilized in afterwards thermocline, thereby make the contained nutritive salt of deep sea water be stabilized in euphotic layer, increase production through photosynthesis promotion plankton, improve the ecotope of shoal of fish self-sow, guarantee the sustainable development of fishery resources, and then improve the marine economy income of China.
The present invention is by wave gas collecting apparatus, wireway, magnetic valve, air bag, gush riser, anchor block, measuring transducer group and instrument room composition, wave gas collecting apparatus is connected with one end of wireway, another end yoke of wireway is divided into two branch roads of giving vent to anger, wherein the branch road of giving vent to anger is connected with air bag top by magnetic valve, another branch road of giving vent to anger stretches into and gushes riser near bottom position from gushing riser sidewall, air bag bottom by load-bearing cable with gush riser and be connected, measuring transducer group is fixed on gushes riser upper end, measuring transducer group, magnetic valve is all connected with the control module in instrument room by transfer cable wire, described instrument room is positioned at and gushes riser sidewall, power module in instrument room is to control module, the power supply of measuring transducer group, anchor block is fixed on and gushes riser lower end.
Wave gas collecting apparatus, along with wave motion is inflated up and down, is transferred to gas to gush riser and air bag by wireway.Temperature, the degree of depth, the ocean current speed of riser mouth are gushed in the measurement of measuring transducer group, and these parameters are transferred to control module, gush the residing optimum depth of riser by calculative determination.Control module control magnetic valve opens and closes to regulate the aeration quantity of air bag, thereby gushes the riser degree of depth by buoyancy control, while gushing riser arrival optimum depth, after the eutrophy deep sea water in lifting mixes with surface seawater, will be stabilized in thermocline.
The present invention is before use first by extremely certain airbag aeration atmospheric pressure, make air bag first across the sea floating, again by the parameter acquisition of measuring transducer group, Autonomous determination gushes the applicable degree of depth of riser mouth, the aeration quantity that regulates again air bag by controlling the switching of magnetic valve, makes to gush riser and is independently adjusted to appropriate depth.
The present invention can be gushed by adjusting the degree of depth of riser, make the deep sea water that is rich in nutritive salt elevating through being stabilized in thermocline after mixing with surface seawater, can not be deposited to very soon euphotic layer once, make the nutrient concentration of euphotic layer increase, significantly improve the facilitation of artificial upwelling to phytoplankton growth.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram that gushes riser for the artificial upwelling of Self Adaptive Control;
Fig. 2 is the flow chart that gushes the control of riser depth adaptive.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the artificial upwelling of Self Adaptive Control gushes riser system and comprises wave gas injection device 1, air bag 4, wireway 2, magnetic valve 3, head-rope 5, gushes riser 6, balancing weight 7, profile survey sensor group 8, instrument room 9.
