The invention relates to a self-powered underwater navigation flow velocity measurement and illumination device and method, the device is formed by welding a metal frame, and a partition plate in the middle of the metal frame divides the device into a flow-induced vibration module and an electromagnetic module. The flow-induced vibration module is located in a large area on the left side of the partition plate and comprises three serial rhombic columns supported by springs and a waterproof rubber diaphragm. When water flow passes through the rhombic column, a vortex street is formed behind the rhombic column, pressure difference is generated, the rubber diaphragm deforms, the permanent magnet is driven to horizontally move and shuttle the coil, and electric energy is generated. Meanwhile, the deformation degree of the rubber diaphragm reflects the flow speed flowing into the metal frame, and the actual flow speed of the ocean current can be obtained by subtracting the running speed of the underwater robot from the flow speed.
本发明涉及一种自供能水下航行测流速与照明的装置及方法,装置由金属框架焊接组成,金属框架中间的隔板将装置分为流致振动模块和电磁模块两部分。流致振动模块位于隔板左侧较大的区域,包含三根由弹簧支撑的串列菱形柱和一块防水的橡胶隔膜。电磁模块位于隔板右侧,当水流通过菱形柱时,在菱形柱后方会形成涡街,产生压差,使橡胶隔膜变形,带动永磁铁平移穿梭线圈,产生电能。同时,橡胶隔膜的变形程度反映了流入金属框架流速的大小,由该流速减去水下机器人自身的运行速度,即可得到海流的实际流速。
