The large-scale tidal current energy electric generation device is internally provided with at least one horizontal shaft water turbine electric generator, the assembly platform comprises supports, at least four fixed piles, at least two nested parts and at least two force-bearingsupporting parts, wherein the fixed piles are connected into a whole through the supports and form an installation space in a surrounding manner, the at least one electric generator is installed inside the installation space, one end of each fixed pile is piled and fixed to a seabed, the other end of each fixed pile extends above the water surface, the at least four fixed piles are arranged in left and right two columns in the water flow direction, and the at least two fixed piles in each column are arranged in the water flow direction in sequence and the at least one fixed pile of the at least two fixed piles in each column is taken as a main load pile; the at least two nested parts are separably arranged on the main load piles on the left and right two sides of the at least one electricgenerator in a sleeving manner correspondingly; and one ends of the at least two force-bearing supporting parts are installed on the left and right two sides in the water flow direction of a horizontal shaft water turbine correspondingly, and the other ends of the at least two force-bearing supporting parts are respectively provided with the nested parts correspondingly to withstand the impact force of water flow on the at least one horizontal shaft water turbine electric generator.
Description
Technical field [0001] The invention belongs to the field of tidal energy power generation, and particularly relates to a large-scale tidal energy power generation device and an assembly platform thereof. Background technique [0002] Ocean energy (including tidal energy, wave energy, temperature difference energy, salinity difference energy, ocean current energy, etc.) is a clean and pollution-free renewable energy with abundant reserves and wide distribution, which has excellent development prospects and value. Nowadays, energy is increasingly scarce, the greenhouse effect is becoming more and more serious, and energy needs to be low-carbon. Therefore, clean energy such as wind energy and ocean energy is the development direction of future energy. However, these clean energy power generation equipment, in addition to the relatively mature utilization of wind energy, the utilization of ocean energy is still in its infancy, and there is no universal and mature equipment, and the ...
