Free liquid level air suction vortex eliminating device
The invention relates to the field of hydraulic and hydroelectric engineering facilities, and discloses a free liquid surface air suction vortex eliminating device which comprises a buoyancy cover plate 4 floating on a free liquid surface, and a top cover 2 higher than the liquid surface is arranged on the buoyancy cover plate 4; a driving assembly and a driven assembly are arranged in the second through hole 21. The driving assembly comprises a hollow driving shaft sleeve 10, blades 7 fixed to the outer wall of the driving shaft sleeve 10 and located below the buoyancy cover plate 4 and a driving transmission assembly. The driven assembly comprises a driven rotating shaft 11, a vortex lifting spiral wheel 12 and a driven transmission assembly; a spiral blade of the vortex lifting spiral wheel 12 is opposite to a water flow vortex in direction; the blade 7 drives the vortex lifting spiral wheel 12 to rotate, and rotation of free liquid surface suction vortexes is restrained and eliminated. Power is provided for eliminating or weakening negative influences caused by vortexes by means of strong rotating flowing of the part, close to the water surface, of free liquid level vortexes, and the device has the advantages of being environmentally friendly, self-powered, simple in structure, flexible in operation, safe, stable, efficient and durable in operation.
本发明涉及水力水电工程设施领域，其公开了一种自由液面吸气漩涡消除装置，包括漂浮于自由液面的浮力盖板4，浮力盖板4上设有高于液面的顶盖2；第二通孔21内设有主动组件和从动组件，主动组件包括中空的主动轴套10、固定于主动轴套10外壁且位于浮力盖板4下方的叶片7以及主动传动组件；从动组件包括从动转轴11、提涡螺旋轮12和从动传动组件；提涡螺旋轮12的螺旋形叶片与水流漩涡方向相反；叶片7带动提涡螺旋轮12旋转，抑制消除自由液面吸气漩涡的转动。本发明依靠自由液面漩涡靠近水面部分的强旋转流动提供动力消除或者减弱漩涡造成的消极影响，具有绿色环保，动力自给，结构简单，运行灵活，安全稳定且高效持久运行的特点。
