Wind energy is a clean energy with abundant reserves and zero cost. It is a clean energy without pollution. It utilizes the inexhaustible and inexhaustible wind energy in nature to generate electricity. It is the best choice for windy areas, especially remote areas. An economical and feasible power supply method, the traditional wind power generation device mainly captures wind energy from a single direction. Low and cannot effectively use wind energy for power generation

The invention discloses a tumbler-type non-linear magnetic disturbance multi-wind direction wind piezoelectric power generation device, which relates to the technical field of new energy power generation and can capture wind energy in any direction for piezoelectric power generation. This device consists of two parts of the power generation unit: the first part is the magnetic vibration power generation part. The wind from any direction exerts an excitation on the cylindrical rigid body. Under this excitation, the cylindrical rigid body drives the tumbler stabilizer to swing, and the piezoelectric vibrator is generated under the disturbance of the magnetic force. Non-linear vibration response, converting wind energy into electrical energy; the second part is the collision power generation part, the swing of the tumbler stabilizer and the magnetic disturbance make the balance beads in the tumbler stabilizer roll, hit the piezoelectric fiber layer, and the piezoelectric fiber layer generates deformation to generate electricity. The invention not only adapts well to the natural wind environment, but also adopts a circular array arrangement to improve power generation efficiency, and solves the limitation and low efficiency problem that the piezoelectric power generation device can only receive wind from a single direction in the past.
Description
technical field [0001] The invention belongs to the field of energy capture of nonlinear magnetic vibration power generation and piezoelectric power generation, and specifically relates to a tumbler-type nonlinear magnetic disturbance multi-wind wind piezoelectric power generation device. Background technique [0002] With the rapid development of the electromechanical industry, wireless sensor technologies such as micro-electromechanical systems (MEMS) and low-power embedded technologies are increasingly becoming integrated, intelligent, and miniaturized. Therefore, higher demand has been put forward for its energy supply industry. However, due to the stagnation of the traditional energy supply industry, the shortcomings of battery power supply have gradually emerged (small capacity, short life, difficult recycling, easy to cause heavy metal pollution) , seriously restricting the development of wireless sensing technology. Using clean energy to power low-energy electronic ...
