Abstract

The invention relates to a marine instrument and meter power supply device based on sea wave energy capture. The traditional piezoelectric generating device has low generating efficiency. The device comprises a seal ball, metal cantilever beams, a mass block, a rectifying circuit and a super-capacitor, wherein the mass block is arranged at a ball center in the seal ball; six strip flaky metal cantilever beams are arranged in the seal ball along the space three-dimensional axial direction; two metal cantilever beams are arranged in each axial direction and positioned at both sides of the mass block; one end of each metal cantilever beam is fixed to the inside wall of the seal ball, and the other end extends into a rectangular groove which is correspondingly opened on the mass block; the metal cantilever beams and the rectangular grooves form slide fit; the upper surface and the lower surface of each metal cantilever beam are correspondingly provided with energy converting devices, the outputs of the energy converting devices are connected with the input of the rectifying circuit, and the output of the rectifying circuit is connected with the super-capacitor. The invention can obtain persistent power supply by utilizing the endless motion of waves.

Description

technical field [0001] The invention belongs to the technical field of energy and electronics, and in particular relates to a power supply device for marine instruments and meters based on ocean wave energy capture. Background technique [0002] The ocean has played a huge role in the economic and social development of my country's eastern coastal areas. The ocean is the main carrier for the transportation of goods and commodities, and it is also the treasure house of the most abundant material resources on the earth. Marine resources have great potential for development. At present, my country has increased investment and development in the field of marine technology, but in the power supply system of marine equipment and instruments that require their own power supply, solar cells, lithium-ion batteries and fuel cells are currently being researched and applied. Solar cells can provide long-term power supply for offshore instruments and equipment placed outdoors, but they a...
