When the device works, the galloping energy collecting device based on dynamic magnetic coupling is placed in fluid, and a pair of piezoelectric composite fiber material sheets are connected with an external circuit through a lead. When fluid flows through the semi-cylindrical blunt body, a relaxation force with a negative damping effect is generated. Under the action of the galloping vibration, the elastic beam generates transverse vibration to drive the pair of piezoelectric composite fiber material sheets to deform and output voltage, so that the kinetic energy of the fluid is converted into electric energy, and further the galloping vibration energy collection is realized.
In this process, a dynamic magnetic repulsion force is generated between the pair of bar permanent magnets a and the pair of bar permanent magnets B. Under the action of dynamic magnetic repulsion, the elastic beam can jump frequently between the two magnetic force potential energy traps more easily, so that the pair of piezoelectric composite fiber material sheets are in a buckling state, and large-amplitude strain energy is converted into electric energy. By moving the energy conversion mechanism, the distance between the pair of bar permanent magnets a and the pair of bar permanent magnets B can be adjusted, thereby coarsely adjusting the dynamic magnetic repulsion. The specific coarse adjustment process is as follows: first, the pair of compression nuts B is loosened. Then, the rectangular pressing plate is vertically moved, and the rectangular pressing plate drives the pair of square-head bolts B, the pair of compression nuts B, the elastic beam, the pair of piezoelectric composite fiber material sheets, the pair of strip-shaped permanent magnets A and the semi-cylindrical blunt body to vertically move together, so that the distance between the pair of strip-shaped permanent magnets A and the pair of strip-shaped permanent magnets B is changed. And (4) when the pair of strip-shaped permanent magnets A move to the designated position, screwing the pair of compression nuts B. By adjusting the dynamic magnetic potential energy adjusting mechanism, the distance between the pair of strip permanent magnets A and the pair of strip permanent magnets B and the supporting force of the supporting spring can be adjusted, so that the dynamic magnetic repulsion force is finely adjusted. The specific fine adjustment process is as follows: the cylindrical housing is rotated so that the pair of spiral chutes are rotated. Under the drive of a pair of spiral spout, a pair of spacing projection A removes to vertical section from the horizontal segment of a pair of L shape spout earlier, rises along the vertical section of a pair of L shape spout again, drives circular tray A from this and rises, and circular tray A promotes circular tray B through supporting spring and rises, drives a pair of spacing projection B and a pair of bar permanent magnet B from this and rises to make the distance between a pair of bar permanent magnet A and a pair of bar permanent magnet B reduce. When the pair of limiting convex columns B rise to the narrowing positions of the pair of L-shaped sliding grooves, the circular tray B stops rising, the circular tube-shaped shell continues to rotate at the moment, the circular tray A continues rising, the supporting spring is shortened, and the supporting force of the supporting spring is increased.
Based on the process, compared with the traditional galloping energy collecting device, the galloping energy collecting device based on dynamic magnetic coupling widens the flow speed range for realizing large-amplitude vibration response by utilizing the magnetic coupling bistable state on one hand, and introduces an elastic supporting mode on the other hand, so that the potential energy barrier height and the coupling frequency are reduced. Therefore, in low-speed and variable-speed fluid, the invention can realize large-amplitude interwell vibration response and convert large-amplitude vibration energy into electric energy, thereby effectively widening the working flow velocity range and effectively improving the energy collection efficiency.
The galloping energy collecting device is reasonable in structure and ingenious in design, effectively solves the problem that the energy collecting efficiency of the traditional galloping energy collecting device in low-speed and variable-speed fluid is low, and is suitable for galloping energy collection.
