Abstract

The invention discloses a piezoelectric power generation system for collecting wave energy based on flexure enhancement. The system comprises an ellipsoidal shell, a variable cross-section sandwich structure cantilever beam, a bottom balancing weight, a cantilever beam free end balancing weight and a support. Mechanical energy carried in the water flow movement process of rivers, oceans and the like is converted into electric energy, then continuous electric energy is provided for all river engineering monitoring equipment or systems, and an important guarantee is provided for achieving an online real-time monitoring system. The system has the characteristics of wide frequency band, all-weather operation, high energy density, simple structure, easiness in industrial production and realization of miniaturization and integration.

Description

technical field [0001] The invention belongs to the field of environmental energy collection and utilization, in particular to a piezoelectric power generation system for collecting wave energy based on deflection enhancement. Background technique [0002] With the intensification of the energy crisis, people began to explore the development and utilization of new clean energy (such as solar energy, ocean wave energy, wind energy and river water energy, etc.). The movement of rivers on the surface "carries" abundant mechanical energy. It has a high energy density and is not affected by rainy weather, so it can provide all-weather energy supply. Traditional river hydropower generation is mainly based on the construction of large dams, with the help of corresponding devices to drive motors to convert water energy into electrical energy. These water energy conversion devices have complex structures and high maintenance costs. On the other hand, in recent years, the country ha...
