The invention discloses an underwater mooring type ocean current energy power generation system which comprises a buoyancy stabilizing unit, a transmission cabin connected with the buoyancy stabilizing unit, an impeller connected with the transmission cabin, an anchor chain connected with the transmission cabin and an anchor connected with the anchor chain. An olive-shaped main engine room is arranged in the buoyancy stabilizing unit, and the olive-shaped main engine room is used for reducing water flow resistance; the generator and the gear box are arranged in a vertical olive-shaped main engine room, an impeller main shaft and other transmission bearings are designed in a non-watertight mode, and the friction resistance of the main shaft is reduced. According to the system, a high-pressure air sealing technology is used, part of water is allowed to enter the bottom of a main engine room, other parts of the main engine room adopt airtight design, high-pressure gas is filled into the olive-shaped main engine room, the water level of the main engine room is kept at a preset position, and condensate water in the main engine room flows to the bottom along the wall of the olive-shaped engine room and is discharged under the action of the high-pressure gas in the engine room. The energy conversion efficiency of the generator is improved, the cost is reduced, and the sea adaptability is improved.

    本发明公开了一种水下系泊式海流能发电系统,包括浮力稳定单元、与所述浮力稳定单元相连的传动舱、与所述传动舱相连的叶轮、与所述传动舱相连的锚链以及与所述锚链相连的锚;浮力稳定单元内设置有橄榄型主机舱,主机舱采用橄榄型,目的在于减少水流阻力;发电机和齿轮箱至于直立的橄榄型主机舱内,叶轮主轴和其他传动轴承采用非水密设计,降低主轴摩擦阻力。系统使用高压空气密封技术,主机舱除了底部允许部分进水外,其他部位采用气密设计,在橄榄型主机舱内部充入高压气体,使主机舱的水位保持在预定位置,主机舱内冷凝水则沿橄榄型舱壁流到底部,在舱内高压气体的作用下排出。本发明提高发电机能量转换效率,降低成本,提高海域适应性。
