The present invention provides a large tidal current energy generating device and an assembly platform () thereof. At least one horizontal axis hydro-generator () is installed in the assembly platform (). The assembly platform () includes at least four fixed piles (), at least two force-bearing blocks (), at least two force-bearing supports (), and supports (). The at least four fixed piles are connected through 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 fixed pile is driven to be fixed to a seabed and the other end 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 each column of the fixed piles is arranged along the water flow direction. 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 horizontal axis hydro-generator below the water surface, respectively. Ends of the at least two force-bearing supports are respectively mounted on the left and right sides of the horizontal axis hydro-generator relative to the water flow direction and the other ends are respectively against the corresponding force-bearing blocks.

Large tidal current energy generating device and assembly platform thereof

The disclosure provides a sealing system applicable for an ocean power generation device, which includes at least one first seal and a water leakage protection device. The water leakage protection device is located at a side of at least one first seal away from seawater, and includes a sealed water storage tank and a drain pipe. The sealed water storage tank collects and stores seawater leaked from the at least one first seal. One end of the drain pipe is communicated with the sealed water storage tank, and the seawater stored in the sealed water storage tank is discharged through the drain pipe.

Sealing system for ocean power generation equipment

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.

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.
