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 relative to a water flow direction, and at least two fixed piles in each column are arranged in sequence along the water flow direction;
• at least two force-bearing blocks, wherein the at least two force-bearing blocks are fixed to the corresponding fixed piles or supports and located on left and right sides of the at least one horizontal axis hydro-generator below the water surface, respectively;
• 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 relative to the water flow direction, and other ends of the at least two force-bearing supports are respectively connected with the corresponding force-bearing blocks so as to resist an impact force of a water flow on the at least one horizontal axis hydro-generator;
• and
• at least one personnel passage, wherein one end of the at least one personnel passage is located above the water surface, and another end of the personnel passage communicates with the horizontal axis hydro-generator, one of the force-bearing supports, or one of the force-bearing blocks, enabling access below the water surface through the at least one personnel passage to perform maintaining or fixing operations.
