The utility model provides an underwater shafting rotating protection device for tidal current energy power generation and a tidal current power generation device. The underwater shafting rotating protection device for tidal current energy power generation is suitable for protecting underwater shafting, the shafting comprises a rotary shaft and at least one bearing, and the rotary shaft is sleeved with the bearings. The underwater shafting rotating protection device for tidal current energy power generation comprises a lubricant storage box, at least two sealing rings and a guide pipe. Lubricant is stored in the lubricant storage box, and the lubricant storage box is located on the water face. The rotary shaft is sleeved with the at least two sealing rings, and a lubricant cavity is formed among the two sealing rings and the shafting. One end of the guide pipe is communicated with the lubricant storage box, and the other end of the guide pipe is communicated with the lubricant cavity. The underwater shafting rotating protection device for tidal current energy power generation can effectively prevent outside impurities, especially sediment in water, from entering the shafting, and therefore normal work of the bearings is effectively protected.
