Document Type and Number:
WIPO Patent Application WO/2021/196243
Kind Code:
A1
Abstract:
A port channel navigation warning device, comprising a floating plate (1), wherein a housing (2) is fixedly connected to the top of the floating plate (1), and the inner walls of two sides of the housing are rotationally provided with the same rotating shaft (3). By providing a solar cell panel (6), the rectangular floating plate (1) and a motor (11), the navigation warning device can generate electric energy and does not need to continuously supplement energy consumed by light emission of the navigation warning device, and the use thereof is thus convenient. In addition, a navigation mark warning lamp will be automatically turned off when electric energy is supplemented in the daytime, which reduces unnecessary energy wastage.
