Embodiment 1
[0042] refer to Figure 1-12 , a multi-stage anti-seismic and anti-overturning linkage device for a bridge, comprising a bridge deck 1 and a single bridge pier 2, there are several single bridge piers 2 equidistantly arranged at the bottom of the bridge deck 1, and the two sides of the single bridge pier 2 are respectively fixedly connected with rigid extensions Plate 3, a vibration-damping support device 4 and an electromagnetic support device-5 are arranged between the top side of the rigid extension plate 3 and the bottom side of the bridge deck 1, and the vibration-damping support device 4 is located at the side of the electromagnetic support device-5 away from the single pier 2 On one side, a cable-stayed support device 6 is provided between the single pier 2 and the bottom edge of the bridge deck 1, and the top of the cable-stayed support device 6 is located vertically above the middle of two adjacent single bridge piers 2, A mercury switch one 7 and a mercury switch two...
Embodiment 2
[0057] Such as image 3 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the internal gears 4112 in the internal gear set 411 of the vibration-damping support device 4 mesh with each other, and the outer large gear ring 4111 drives the internal gear 4112 and the central shaft gear 4113 in turn.
[0058] In this embodiment, the mechanical energy generated by the upper bridge is amplified by the gear set 411 and then transmitted to the generator 413 .
Embodiment 3
[0060] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the inside of the electromagnetic box 504 is fixed with a cylindrical solid steel-505 with coils, and the material of the cylindrical solid steel-505 iron core is iron-aluminum alloy, and the internal coils are uniform. It is a copper coil, the number of turns is between 3000-7000, and the diameter is between 100-300mm.
[0061] In this embodiment, it is convenient for efficient transmission of electric current and generation of electromagnetic attraction and repulsion.
