Active feathering type chimney enclosure structure capable of resisting strong wind and operation method
The invention provides an active feathering type strong-wind-resistant chimney enclosure structure and an operation method, and belongs to the technical field of chimney protection.The chimney enclosure structure comprises a plurality of blade element enclosure structures used for being arranged on the outer side of a chimney in a sleeving mode and a plurality of sliding rails used for being fixedly arranged on the outer side of the chimney in a sleeving mode; each slide rail comprises a first slide way with an upward opening and a second slide way with a downward opening; the blade element enclosure structure is in a streamline body shape, the top of the blade element enclosure structure is provided with a first pulley block matched with the first sliding way, and the bottom of the blade element enclosure structure is provided with a second pulley block matched with the second sliding way. According to the invention, the streamline body appearance is adopted, so that vortex shedding is not generated when wind flows through the surface of the blade element, the transverse wind load generated by vortex shedding is effectively reduced, and the vortex-induced resonance phenomenon can be avoided.
本发明提供了一种主动顺浆式可抗强风的烟囱围护结构及作业方法，属于烟囱防护技术领域，所述烟囱围护结构包括：用于套设在烟囱外侧的多个叶素围护结构以及用于套设固定在烟囱外侧的多条滑轨，每条滑轨均包括开口朝上的第一滑道和开口朝下的第二滑道；叶素围护结构为流线体状，叶素围护结构的顶部设有与第一滑道配合的第一滑轮组，叶素围护结构的底部设有与第二滑道配合的第二滑轮组。本发明采用的流线体外形使得风流过叶素表面时不产生漩涡脱落，有效降低了因漩涡脱落产生的横向风荷载，并且可规避涡激共振现象。
