Abstract
The utility model discloses an hourglass-shaped piezoelectric power generation device in the field of piezoelectric power generation. The hourglass-shaped piezoelectric power generation device comprises multiple hourglass-shaped piezoelectric plates which are identical in structure and arranged in parallel. The top parts of the piezoelectric plates are fixedly connected together via a mass plate. The bottom parts of the piezoelectric plates are fixedly connected together via a bottom plate. Each piezoelectric plate comprises upper and lower horizontal pieces and four central inclination pieces. The surfaces of the two ends of each inclination piece are correspondingly pasted with two pairs of piezoelectric sheets. Connection between the horizontal pieces and the inclination pieces and connection between the inclination pieces are realized in a curved-surface way. The hourglass-shaped piezoelectric power generation device is simple in structure, wide in application range, high in power generation amount and high in energy collection efficiency so that the hourglass-shaped piezoelectric power generation device can be applied to occasions with high people and traffic flow like roads, market entrances and pedestrian streets, and can also be applied to vibration occasions like body-building pedals, ships and stages.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), particularly a kind of piezoelectric generating device.
Background technology
Piezo-electric generating is to utilize the direct piezoelectric effect of piezoelectric ceramic to realize the conversion of mechanical energy to electric energy, piezoelectric generating device by special piezoelectric by the collection of energy of vibrating in environment, and to convert thereof into can substituting battery be the electric energy of microelectronic product power supply, become a focus in MEMS research field.
At present, beam type piezoelectric generating device is the oscillatory type energy harvester of commonly using the most, main by the direct piezoelectric effect of piezoelectric ceramic piece, and vibrational energy is changed into electric energy.But beam type piezoelectric generating device has a very serious defect, that is exactly only larger at the local strain ratio near cantilever beam root, paste piezoelectric patches and just can produce larger electric weight, other place is because strain is less, so generally do not paste piezoelectric patches, thereby cause beam type piezoelectric generating device can utilize part few, floor space is large, energy output is little, and is difficult to below occasion that the stream of peoples such as highway, market entrance, shopping mall, vehicle flowrate are larger.And these places often have larger vibrational energy, if can be good at collecting, will produce huge electric weight, not only instead of chemical battery on a large scale, can also, to our power supply of partly living, even solve some electricity consumptions from far-off regions.
Utility model content
