Technical field
The utility model belongs to ocean equipment technology and Ocean Fishery Field, relates to a kind of seabed nutritive salt gas injection lifting device.
Background technology
Marine economy has become the important component part of Chinese national economy.Through 50 years of development, the sea fishery of China is by expansion of technological progress, production marine site and renewal of the equipment, aquatic products year amount of fishing be doubled and redoubled, abundant marine product has been made major contribution for the living standard that improves China people.But, continuous increase along with fishing boat power, contradiction between powerful fishing capacity and limited operation fishing ground, the fragile resource base is becoming increasingly acute, cause China's marine fishery resources slump of disastrous proportions, immediate offshore area deterioration of the ecological environment trend fails effectively to be contained, the sustainable development of serious threat China sea fishery.For example, as the concentrated producing region of the main economic fish of China, Zhoushan Fishing Ground economic fish in recent years can not form fishing season substantially.How effectively to contain immediate offshore area deterioration of the ecological environment trend, carry out fishing off season, improve the ecotope of shoal of fish self-sow, enlarge the fishing ground scope, form new fishing ground and also begin to become important means with manual method except utilizing administrative way.
The key that the seawater wild fish increases production naturally is to improve the environmental condition of seawater fish food chain, pays attention to replenishing of photic zone maritime interior waters nutrient component.The nutritive salt in marine site is the indispensable nutrition of phytoplankton and fish growth.In the euphotic layer of ocean, phytoplankton growth and breeding are arranged, they constantly absorb nutritive salt, especially at neritic zone, because the breeding of phytoplankton and grow vigorously during summer makes the nutritive salt approach exhaustion in the superficial water; And under the euphotic layer of ocean, nutrient concentrations increases sharply with the degree of depth.Rise to ocean surface if nutritive salt can be gushed by seawater, produce a large amount of planktons through photosynthesis, this marine site has just become halobiontic fertile soil.So main in the world fishing ground is distributed in upwelling mostly frequent marine site takes place.If can be in the marine site that natural upwelling lacks, take manually to produce the mode of upwelling, a large amount of deep layer eutrophy sea brines are promoted to the place that marine superstructure light can arrive, cooperate carbonic acid gas, photosynthesis takes place make the phytoplankton volume increase, as other halobiontic food, form food chain, can create new fishing ground.Reach deep sea water is evacuated to marine superstructure to produce the fishing ground, can adopt different technology.At present, domestic do not have as yet a kind ofly can realize that seabed, shallow sea nutritive salt is gushed the device that is raised to ocean surface by gas injection under water to appear on the market.
Summary of the invention
The purpose of this utility model is to overcome the influence of the immediate offshore area deterioration of the ecological environment to the fishery resources sustainable development, the marine site that while lacks at natural upwelling, with duct type seabed, shallow sea nutritive salt gas injection lifting device nutritive salt is gushed by seawater and to rise to ocean surface, produce a large amount of planktons through photosynthesis, thereby improved the ecotope of shoal of fish self-sow, enlarged the fishing ground scope, guaranteed the sustainable development of fishery resources, improve the people's living standard, and then improved the marine economy income of China.
The concrete scheme that the utility model technical solution problem is taked is:
The utility model is disposed with sea gas injection device, gas delivery tube road and nutritive salt lifting device from top to bottom.The sea gas injection device is communicated with an end in gas delivery tube road, and the other end in gas delivery tube road is communicated with the nutritive salt lifting device.
The sea gas injection device comprises air pump system and floating platform.Described air pump system comprises air pump, flow control valve and flowmeter, and the gas outlet of air pump is connected with the input port of flow control valve, and the delivery outlet of flow control valve is connected to floating platform, and the pipeline between flow control valve and the floating platform is provided with flowmeter.Described floating platform inner hollow forms air storage chamber.
The nutritive salt lifting device comprises seabed air chamber and Duo Gen nutritive salt riser tubing, sidewall has a plurality of through holes around the air chamber of described seabed, the nutritive salt riser tubing is communicated with the seabed air chamber by corresponding through hole, described nutritive salt riser tubing is radiation around the seabed air chamber and distributes, and every nutritive salt riser tubing has the venthole of opening towards the sea.
Duct type seabed, the shallow sea nutritive salt gas injection lifting device efficient height that the utility model adopts, energy consumption is low, can be the fishing ground cultivation of China and recovers to have given play to important effect.The utility model can be the ocean dynamoelectric equipment of biphase gas and liquid flow and provides fundamental basis and technological accumulation, simultaneously seabed nutritive salt under water the involved theoretical result of gas injection lifting means also will obtain using more widely in fields such as plant equipment such as the deicing equipment of marine environment reforming equipment, northern harbour or river water conservancy project system, sewage treatment equipments.
