The ocean temperature difference energy has the characteristics of huge reserves and relative stability along with time change, so that large-scale and stable electric power is hopefully provided by utilizing the ocean temperature difference energy for power generation. The thermoelectric power generation technology is a technology which uses surface seawater (25-28 ℃) heated by solar energy of the ocean as a high-temperature heat source, uses deep seawater (4-7 ℃) at the depth of 500-l 000 meters as a low-temperature heat source, and uses a thermal circulation system consisting of heat engines to generate power. From a high-temperature heat source to a low-temperature heat source, effective energy with the total temperature difference of about 15-20 ℃ can be obtained. It is possible to obtain energy with an engineering-meaningful temperature difference of 11 c. The existing thermoelectric power generation thermodynamic cycle system is divided into an open cycle, a closed cycle and a mixed cycle, wherein the open cycle and the mixed cycle can produce fresh water as a byproduct. The thermoelectric power generation device has the defects that the energy conversion efficiency is only 5% -10%, and in contrast, the conventional thermal power efficiency exceeds 40%, and the efficiency of a large hydroelectric generating set is up to 90%. The inefficiency, low installed capacity and relatively high cost make ocean thermal energy lack the ability to compete with traditional thermal power and hydropower in shallow offshore water areas. However, ocean temperature difference energy has great development potential in deep sea ocean engineering: on the one hand, on a floating ocean platform far away from land, the traditional energy source is extremely popular; on the other hand, the electric energy generated by the open sea power generation device is high in cost, great in difficulty and low in feasibility when being transmitted back to the continent.

3) The prior art also has the advantages that wave energy power generation, ocean current power generation, solar power generation and other modes are used for supplying energy to the offshore platform, but the power generation mode has the defect of small single-machine power generation power, and the power generation power is greatly influenced by sea conditions.
4) In the prior art, wave-driven temperature difference energy is used for generating electricity, or wave energy electricity generation and wind energy electricity generation are combined, but the wave-driven temperature difference energy and wind energy electricity generation are only a single electricity generation platform and have no other production operation functions.
5) In the prior art, a water taking system of a cold water mass is designed by depending on a culture ship, but the water taking system is only suitable for sea areas with shallow water depth of yellow sea, and the water taking depth is less than 50 meters.
