Abstract

The invention discloses a deep sea current fluctuation energy piezoelectric power generation device. The device comprises a box, sector structures and connecting rods. The box is a cube having an internal cavity, and one end of each connecting rod is fixedly connected on each external surface of the cube and the other end of each connecting rod is connected with each sector structure. Each sectorstructure comprises four piezoelectric power generation parts and a fixing part, and the piezoelectric power generation parts are evenly arranged on the external side surface of the fixing part. Eachpiezoelectric power generation part comprises a plate which is fixedly connected with the external side surface of the fixing part, an S-shaped blade which is fixedly connected with the plate and piezoelectric ceramic sheets which are fit on the upper and lower surfaces of the plate. When the device works, the box, the sector structures and the connecting rods form a multi-degree-of-freedom motionsystem to generate relative motion under excitation of the current fluctuation energy and realize conversion of the mechanical energy to the electric energy through the direct piezoelectric effect ofthe piezoelectric ceramic sheets so that the blank of the self-powered deep sea probe can be filled, the number of the motion modes is high and the energy utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of ocean current wave energy power generation, in particular to a deep ocean current wave energy piezoelectric power generation device. Background technique [0002] Ocean current wave energy is one of the most abundant energy sources in ocean energy, and it exists in the form of mechanical energy. The development process has little impact on the environment and is the highest quality ocean energy. [0003] With the development of modern science and technology, various self-powered detectors based on piezoelectric sea surface floating have been proposed, but the generator principle of the above-mentioned self-powered detectors is complicated, the movement mode is small, and the energy utilization rate is low, and it is only applicable to the sea surface Floating power generation. Contents of the invention [0004] The object of the present invention is to provide a deep ocean current wave energy piezoelec...
