CN101814859B – Wave Power Piezoelectric Generating Device – Google Patents

Neurocirugia_Vol2_Cap18 In the foregoing description, each piezoelectric vibrator 18 can adopt with each scribing 19 and be a layer arrangement, and promptly the piezoelectric vibrator on each layer 18 is positioned at same horizontal plane with scribing 19, and number is identical; Each piezoelectric vibrator 18 can also adopt arrangement mode (as shown in Figure 6) with each scribing 19, and promptly the form that rises in the shape of a spiral each other of the every row piezoelectric vibrator 18 on generator leg 10 is carried out the changing of the relative positions, and the scribing 19 on the power transmission shaft 13 keeps being the mode that layer is arranged. In the foregoing description, supporting floating body 3 is wrapped in buoyancy aid 4 wherein, and connects through a rigid links 17 (as shown in Figure 2) at the opening part of the supporting floating body that is n shape 3, and then through the reflection incoming wave, improves the efficient that wave energy collection device 1 is collected wave energy.

Suffering, pain, pain. Patent number mainly is made up of floating buoyancy aid and one group of piezoelectric patches across the sea for the piezoelectric Wave energy converter in the design of US4685296 patent.Buoyancy aid compresses in the process of moving up and down and the stretching piezoelectric patches, makes it that strain take place, and at the mounted on surface electrode of material, utilizes the exportable electric energy of the distinctive piezoelectric property of material.U.S. Said scribing adopts nickel, steel or steel alloy to process, or adopts a magnet to process; Said piezoelectric vibrator is connected by two kinds of materials to be processed; Adopted epoxy resin, polysulfones or aluminum alloy materials by said piezoelectric patches institute region covered on it; All the other adopt cast zinc alloy, copper alloy, silicon, steel or alloy steel material near the zone of end, and the natural frequency of said piezoelectric vibrator is 10~120Hz; Perhaps fixing respectively another piece magnet on the upper surface both sides of said piezoelectric vibrator end forms the piezo-electric generating unit of non-contact type magnetic with the said scribing of being processed by magnet.
