Adaptive-control artificial upwelling pipe

Abstract

The invention relates to an adaptive-control artificial upwelling pipe. A wave air collection device is connected with one end of an air guide pipe, the other end of the air guide pipe is divided into two outlet branches, one of the outlet branches is connected with the upper portion of an airbag through a solenoid valve, and other outlet branch extends into the upwelling pipe from the position, close to the bottom, of the side wall of the upwelling pipe. The lower portion of the airbag is connected with the upwelling pipe through a bearing cable. A measuring sensor is fixed to the upper end of the upwelling pipe, the measuring sensor and the solenoid valve are connected with a control module in an instrument cabin through transmission cables, the instrument cabin is disposed on the side wall of the upwelling pipe, and a power module in the instrument cabinet supplies power for the control module and the measuring sensor. An anchor block is fixed at the lower end of the upwelling pipe. By means of regulation of depth of the upwelling pipe, raised deep sea water rich in nutritive salt is stabilized at the thermocline after being mixed with surface sea water, and promotion effect of artificial upwelling to growth of phytoplankton is improved remarkably.

Description

technical field [0001] The invention belongs to the field of marine equipment technology and marine fishery, and relates to an adaptively controlled artificial upwelling riser. Background technique [0002] Natural upwelling is a key ocean physical process, which can bring nutrient-rich deep seawater to the middle and upper layers, making the upwelling area the most productive area in the world's oceans. It can improve the marine ecological environment. [0003] Artificial upwelling is a geoengineering method that uses some devices to lift the deep seawater with low temperature and rich nutrients to the surface, so that the upper layer contains lower nutrient salts to be replenished, forming the exchange of upper and lower layers of water. At present, the contradiction between the strong fishing capacity of my country's fishery and the limited operating fishery and fragile resource base has become increasingly acute, resulting in a serious decline in my country's marine fis...

Problems solved by technology

[0005] Based on the significance of artificial upwelling in the transformation of marine ecology, artificial upwelling has become a hot spot and frontier of marine scientific research at home and abroad, but how to stabilize the elevated nutrient-rich deep seawater in the thermocline, so as not to It will soon sink below the euphotic layer, and then lose the significance of promoting the reproduction of plankton. Domestic research on this issue is still blank
