WIPO Patent Application WO/2023/082225
Kind Code:
A1
Abstract:
A lifting fin device, comprising an enclosure (1), a fin plate (2), a guide assembly (3), and a locking mechanism (4). The bottom portion of the enclosure (1) is provided with an opening. The fin plate (2) is slidably arranged in the enclosure (1) in the vertical direction. The bottom portion of the fin plate (2) can extend out of the enclosure (1) by means of the opening. The guide assembly (3) comprises a sliding rail (31), a sliding block (32) and an elastic member (33); the sliding rail (31) is disposed in the enclosure (1) in the vertical direction; two ends of the elastic member (33) are connected to the fin plate (2) and the sliding block (32), respectively; and the sliding block (32) is slidably arranged on the sliding rail (31). The locking mechanism (4) is disposed in the enclosure (1). A locking end of the locking mechanism (4) is provided to lock the fin plate (2) in a working position. The lifting fin is configured by using described means, so that a fin plate under ocean flow impact may be cushioned, and the problem that when the fin plate descends, the fin plate is damaged due to the effect of ocean flow and collision with a sliding rail may be solved.
