Embodiment 1
[0040] Such as figure 1 Shown is a stacked column type asphalt pavement energy harvesting device, the upper surface top plate 1 and the lower surface top plate 8 are circular with a radius of 11 cm and a thickness of 5 mm. The size of the encapsulation layer 2 is a cylinder with a base radius of 11 cm and a height of 1.6 cm filled with asphalt sand. Between the top plate 1 on the upper surface and the top plate 8 on the lower surface, 21 piezoelectric ceramic column units 3 are densely arranged, wherein the piezoelectric ceramic column unit 3 is formed by stacking three piezoelectric ceramic column bodies 4, and the piezoelectric ceramic column units 3 and A metal sheet 5 is directly provided on the surface top plate, and a metal sheet 5 is provided between each piezoelectric ceramic column body 4 . The piezoelectric ceramic column body 4 , the top plate 1 on the upper surface and the top plate 8 on the lower surface are all bonded by the adhesive layer 6 . The bonding layer...
Embodiment 2
[0046] Such as figure 1 Shown is a stacked column type asphalt pavement energy harvesting device (except that the piezoelectric ceramic column unit 3 is composed of four piezoelectric ceramic column bodies 4, and the other structures are the same as figure 1 same), the top plate 1 on the upper surface and the top plate 8 on the lower surface are circular with a radius of 15 cm and a thickness of 10 mm. The size of the encapsulation layer 2 is a cylinder with a base radius of 15 cm, a height of 8 cm and filled with asphalt sand. Fifteen piezoelectric ceramic column units 3 are densely arranged between the upper surface top plate 1 and the lower surface top plate 8, wherein the piezoelectric ceramic column unit 3 is formed by stacking four piezoelectric ceramic column bodies 4, and the piezoelectric ceramic column units 3 and A metal sheet 5 is directly provided on the surface top plate, and a metal sheet 5 is provided between each piezoelectric ceramic column body 4 . The pie...
