Protecgulum Rear Cover Adds Filter Screen

Laser and lights 2) a kind of flexible piezoelectric power generator based on Karman vortex street effect of the present invention, each composition is as outside Shell, protecgulum, stream stent and fixed link etc. 5) a kind of flexible piezoelectric power generator based on Karman vortex street effect of the present invention, by the way that the device is pacified On pile body loaded on aircraft wing, hull or hydraulic engineering structure, wind energy can be converted but also convert current energy, had a wide range of application It is general. It will These energy collections are applied in the micro radio electronics equipment in the harsh severe place of condition, have not only saved the energy but also have cleaned without dirt Dye, but since the Collection utilization difficulty of these energy is big, and the efficiency converted is than relatively low, so wideless to its utilization at present It is general.The common piezoelectric device to generate electricity now with fluid motion is all to drive shaking for piezoelectrics by the mechanical oscillation of object Dynamic, this collection principle is there are many problems, and if output power is not high, transformation efficiency is relatively low, and manufacture cost is higher, and technology is multiple It is miscellaneous, the problems such as application range is more narrow.

Certainly, the above is only presently preferred embodiments of the present invention, it is impossible to be construed as limiting the implementation to the present invention Example scope.The present invention is also not limited to the example above, and those skilled in the art are in the essential scope of the present invention Interior made all the changes and improvements etc. This device exhibited only aerodynamic flutter. Some oscillating forces were felt by the hand holding the tensioning line at the bottom of the device. Fig. 6 is the schematic diagram that the present invention is mounted in hull bottom face.

One coupling included a metal rod having one end taped to near the bottom fixed point of the tensioning rope, a magnet connected to the rod, and the rod extending horizontally traversing the coil. Preferably, power generator installation number is streamed for two groups, and later group streams chassis plane apart from the flexible pressure of previous group The end of electric piece 2 at least keeps the spacing of 4D, just can guarantee the non-interference influence of effect for streaming generation.

Preferably, flexible piezoelectric piece 2 uses PVDF piezoelectric membranes, if 2 width of flexible piezoelectric piece is D, adjacent two flexible pressures The spacing of electric piece 2 is at least 0.5D, ensures that adjacent two flexible piezoelectrics piece 2 is non-interference, flexible piezoelectric piece 2 and stream stent 1 it Between using directly bonding or hang fix. Further, the opening inner wall of protecgulum and rear cover is also bonded with filter screen, and filter screen is less than 0.1D using diameter Filament work out.The grid spacing of filter screen is D, for preventing that foreign matter of the size more than D enters the device in fluid. Shell 7 be thin wall hollow cylinder, be made of organic material or alloy in lightweight, as PVC plastic, organic glass or Person’s aluminium alloy etc.The device further includes protecgulum 5 and rear cover 3, and protecgulum 5 and rear cover 3 are made of organic material or alloy in lightweight;Outside It is fixed between shell 7 and protecgulum 5 and rear cover 3 using mechanical coupling fashion, stability is high and is easy to dismount.Protecgulum 5 and rear cover 3 are opened Inner wall is also bonded with filter screen 6 at mouthful, and filter screen 6 is worked out using filament of the diameter less than 0.1D.Between the grid of filter screen 6 Away from for D, for preventing that foreign matter of the size more than D enters the device in fluid.
