The magnetic repulsion piezoelectric and magnetic flux variable vibration high-efficiency composite power generation device of the invention belongs to the field of generating electric output from mechanical input, including a vibrator and a magnet fixator, a vibrator and a magnet fixator are relatively arranged, one end of an elastic bracket and one end of a piezoelectric plate are fixed on the vibrator and on the side opposite to the magnet fixator, and the elastic bracket and the piezoelectric plate are integrated, and the piezoelectric plate are also fixed. The length of the elastic bracket is less than that of the elastic bracket, and a counterweight magnet is fixed at the other end of the elastic bracket, and a fixed magnet is fixed on the magnet fixing frame, which is opposite to the counterweight magnet. The induction coil is placed between the counterweight magnet and the fixed magnet. The design of the device is reasonable, the electric power conversion efficiency of vibration mechanical energy is higher and the benefit is greater. The piezoelectric plate is replaced by a composite plate structure of sectional and graded thickness, which makes the stress and strain of each part equal or similar. Adding a coil between the counterweight magnet and the fixed magnet can capture the magnetic flux-variable induction energy, which adds a vibration energy generator mechanism and improves the efficiency and benefit of the system.

磁斥压电及磁通变振动高效复合发电装置
本专利技术涉及从机械输入产生电输出的领域,特别涉及磁斥压电及磁通变振动高效复合发电装置。
技术介绍
目前国家主要的电能还是来自于有较大污染排放的煤电行业,为了提高环境质量,需要发现并收集各种无污染可再生能量发电,如自然界中的振动能量工厂机器、交通车辆道路、矿山开采等环境、波动能量水波、海浪、舰船、浮标波动等、摇摆能量大风吹动大树枝叶摇摆、路牌、人工建筑等。由于振动能量在生产环境中大量存在,现有技术中,将振动能量与压电技术及磁电技术相结合发电过程中,压电材料板多为等厚单层板或等厚多层板结构,所以振动源根部压电材料板的应力大于自由端部位的应力,导致压电板不同部位的应变及表面电荷富集不均匀;磁铁设计能降低压电板材料板的固有频率,产生非线性作用力,扩大频宽提高机电耦合参数,但磁场磁通强度的变化特性并没有被充分被利用。
