Large tidal current energy generating device and assembly platform thereof

An assembly platform of a large tidal current energy generating device, wherein at least one horizontal axis hydro-generator is installed inside the assembly platform, and the assembly platform of the large tidal current energy generating device comprises:

• supports;
• at least four fixed piles, wherein the at least four fixed piles are connected by the supports to form an installation space, the at least one horizontal axis hydro-generator is installed inside the installation space, one end of each of the at least four fixed piles is driven to be fixed to a seabed, the other end of each of the at least four fixed piles extends to be above a water surface, the at least four fixed piles are arranged in left and right columns along a water flow direction, at least two fixed piles in each column are arranged in sequence along the water flow direction, and at least one of the at least two fixed piles in each column acts as a main bearing pile;
• at least two sleeving members, wherein the at least two sleeving members are detachably sleeved on the main bearing pile on left and right sides of the at least one horizontal axis hydro-generator and are located below the water surface, respectively;
• and
• at least two force-bearing supports, wherein ends of the at least two force-bearing supports are respectively mounted on the left and right sides of the at least one horizontal axis hydro-generator along the water flow direction, and other ends of the at least two force-bearing supports are respectively mounted with corresponding sleeving members so as to resist an impact force of a water flow on the at least one horizontal axis hydro-generator.
