Abstract: The present invention provides an assembly platform of a large tidal current energy generating device. The assembly platform is internally provided with at least one horizontal axis hydro-generator. The assembly platform includes supports, at least four fixed piles, at least two sleeving members and at least two force-bearing supports. The fixed piles are connected through the supports to form an installation space. The hydro-generator is installed inside the installation space, one end of each fixed pile is driven to be fixed to a seabed and the other end extends to be above a water surface. Ends of the at least two force-bearing supports are respectively mounted on the left and right sides of the horizontal axis hydro-generator along the water flow direction and the other ends are respectively provided with corresponding sleeving members so as to resist an impact force of a water flow on the horizontal axis hydro-generator.

Abstract: This invention provides a rolling bearing protection device and a vertical-axis tidal current energy generating device applying the same. The vertical-axis tidal current energy generating device includes a frame, a vertical-axis hydraulic generator, a rolling bearing, and a rolling bearing protection device. The vertical-axis hydraulic generator includes a main shaft disposed vertical to a horizontal surface, one end of the main shaft is rotatably disposed at a bottom of the frame. The rolling bearing is sleeved on one end of the main shaft. The rolling bearing protection device is disposed above the rolling bearing. The rolling bearing protection device includes a first sealing protection device, a first water leak-proof chamber, and a second sealing protection device disposed in sequence along a gravity direction.
