Sea bed nutrient lifting device and method based on solar energy and wave energy

Abstract

The invention discloses a sea bed nutrient lifting device and a method based on solar energy and wave energy. In the prior art, the sea bed nutrient lifting method is difficult to implement and has a high energy consumption. The device comprises a sea surface platform, underwater heat-insulating guide tubes and a sea bed heat-absorbing device, wherein the sea surface platform is formed by a top surface and a bottom surface, a compressible plastic heat-insulating water bag surrounds the sea surface platform to form closed space, a support plate is arranged at the middle of the closed space to divide the closed space into two chambers, the two chambers are communicated with each other, the underwater heat-insulating guide tubes are connected to the bottom surfaces of the chambers, and the two underwater heat-insulating guide tubes are communicated through the sea bed heat-absorbing device. Under the action of sea surface waves, the compressible plastic heat-insulating water bag pushes the upper-layer high-temperature sea water to flow into the lower-layer sea bed heat-absorbing device, resulting in heat exchange. The lower-layer sea water absorbs heat energy to lead to temperature rise and density drop and floats up under the action of buoyancy, so that the nutrient-enriched sea water deep in the sea is lifted up to the sea surface. The device and the method have the advantages of high efficiency and low energy consumption and are clean and environment-friendly.

Description

technical field [0001] The invention belongs to the field of marine equipment technology and marine fishery, and relates to a seabed nutrient salt lifting device and method using solar energy and wave energy. Background technique [0002] Marine economy has become an important part of our country's national economy, and the development and utilization of marine fishery resources is an important part of marine economy. However, with the continuous increase of fishing intensity, my country's marine fishery resources have declined seriously in recent years, which has seriously threatened the sustainable development of my country's marine fishery. If the environmental conditions of the seawater fish food chain can be effectively improved, the sustainable development of marine fisheries can be guaranteed fundamentally. Nutrients in seawater are indispensable nutrients for the growth of phytoplankton and fish. However, compared with deep seawater, the concentration of nutrients i...

AI Technical Summary

Problems solved by technology

This method has a fast improvement speed but has great limitations: first, this method is difficult to implement, and it has greater instability when used in a complex marine environment; second, this method requires a large amount of energy consumption

At the same time, there is no domestic device that can lift nutrients from the seabed to the surface of the ocean.
