Embodiment Construction

[0015] The principle and structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 , figure 2 and image 3 As shown, a shallow sea pipeline type subsea nutrient salt gas injection lifting device is provided with a sea surface gas injection device, a gas transmission pipeline 3 and a nutrient salt lifting device in sequence from top to bottom. The sea surface gas injection device communicates with one end of the gas transmission pipeline 3, and the other end of the gas transmission pipeline 3 communicates with the nutrient salt lifting device.

[0017] Such as image 3 and Figure 5 As shown, the sea surface gas injection device includes an air pump system 1 and a floating platform 2 . The air pump system 1 includes an air pump 7, a flow control valve 8 and a flow meter 9. The air outlet of the air pump 7 is connected to the input port of the flow control valve 8, and the output port of the ...

Abstract

The invention relates to a shallow sea pipeline seafloor nutrient salt gas injecting and elevating device which is sequentially provided with a sea surface gas injection device, a gas conveying pipeline and a nutrient salt elevating device from top to bottom, wherein the sea surface gas injection device is communicated with one end of the gas conveying pipeline; the other end of the gas conveying pipeline is communicated with the nutrient salt elevating device; the sea surface gas injection device comprises an air pump system and a floating platform; the air pump system comprises an air pump, a flow control valve and a flow meter; the inside of the floating platform is hollow to form a gas storage chamber; the nutrient salt elevating device comprises a seafloor air chamber and a plurality of nutrient salt elevating pipelines; and the seafloor air chamber is communicated with the plurality of nutrient salt elevating pipelines. The shallow sea pipeline seafloor nutrient salt gas injecting and elevating device has high efficiency and low energy consumption, and can play an important role in cultivating and recovering fishing grounds.

Description

technical field [0001] The invention belongs to the field of marine equipment technology and marine fishery, and relates to a shallow sea pipeline type submarine nutrient salt gas injection lifting device. Background technique [0002] Marine economy has become an important part of our national economy. After more than 50 years of development, my country's marine fishery has doubled the annual catch of aquatic products through technological progress, expansion of production sea areas and equipment renewal. The rich seafood has made a significant contribution to improving the living standards of our people. However, as the power of fishing boats continues to increase, the contradiction between strong fishing capacity, limited fishing grounds, and fragile resource base has become increasingly acute, resulting in a serious decline in my country's marine fishery resources, and the deterioration of the ecological environment in coastal waters has not been effectively controlled. ...
