阅读说明：本技术 一种低流速水力发电机 (Low-flow-speed hydroelectric generator ) 是由 李亦博 李宏春 李锋 于 2018-11-21 设计创作，主要内容包括：一种低流速水力发电机,属于电力设备技术领域。该水力发电机含有承重体,与所述承重体连接的水力转轮,经所述水力转轮直接或间接驱动的发电机；所述承重体与所述水力转轮之间构成轴向约束的水平转动副；所述承重体或所述水力转轮含有浮力装置,所述浮力装置能产生消减所述承重体或所述水力转轮自重的浮力,因而提高发电效率,省去现有潮汐能发电中建堤造库的成本。(A low-flow-speed hydroelectric generator belongs to the technical field of power equipment. The hydroelectric generator comprises a bearing body, a hydroelectric runner connected with the bearing body and a generator directly or indirectly driven by the hydroelectric runner; an axially restrained horizontal rotating pair is formed between the bearing body and the hydraulic rotating wheel; the bearing body or the hydraulic runner contains a buoyancy device which can generate buoyancy for reducing the self weight of the bearing body or the hydraulic runner, thereby improving the power generation efficiency and saving the cost of building a bank in the conventional tidal power generation.)
