The invention discloses a drag reduction device and a breeding platform, and relates to the technical field of drag reduction devices.The drag reduction device is used for drag reduction when the breeding platform sails, the drag reduction device is used for being installed at the stern of the breeding platform, the drag reduction device comprises a pipeline and a sealing assembly, and an inner cavity is formed in the pipeline; openings communicating with the inner cavity are formed in the two ends of the pipeline. The sealing assembly comprises a first control part, a plurality of first sealing plates and a plurality of second sealing plates, the first sealing plates are all mounted at an opening in one side of the pipeline, and the second sealing plates are all mounted at an opening in the other side of the pipeline; the first control part is used for driving the first sealing plates and the second sealing plates to move towards the centers of the openings or move away from the centers of the openings so as to close or open the openings in the two sides of the pipeline. In this way, seawater can enter the pipeline during sailing, the effect of reducing flow resistance can be achieved, and therefore the sailing speed of the breeding platform is increased.
本发明公开了一种减阻装置及养殖平台,涉及减阻装置技术领域,其中,减阻装置用于养殖平台在航行时的减阻,且减阻装置用于安装于养殖平台的船尾,减阻装置包括管道和密封组件,管道形成有内腔,且管道的两端均形成有与内腔相互连通的开口;密封组件包括第一控制部件、多个第一密封板和多个第二密封板,多个第一密封板均安装于管道一侧的开口,多个第二密封板均安装于管道另一侧的开口,第一控制部件用于驱动多个第一密封板和多个第二密封板均朝开口的中心移动或远离开口的中心移动,以关闭或打开管道两侧的开口。这样航行时,海水就会进入管道中,这样能够起到降低流阻的作用,从而提高养殖平台的航速。
