The number of the damping mechanisms 4 of the upper damping mechanism and the lower damping mechanism is at least one, and the installation direction of each group of the damping mechanisms 4 is the same as the auxiliary direction of the guide rail 1 on the same bottom plate 7.
Each set of damping mechanisms 4 contains 1 damper shear 401, 1 damping fluid reservoir 402, and 2 damping fluid seals 403. The damping fluid container 402 is filled with damping fluid, the damper shearing part 401 is composed of an upper flat plate 404, an intermediate connecting vertical plate 405 and a lower flat plate 406, the lower flat plate 406 is immersed in the damping fluid, and the damping fluid is filled in a closing-in inner cavity 407 in the damping fluid container 402.

The working method of the invention comprises the following steps: the movement directions of the upper shock absorption mechanism and the lower shock absorption mechanism of the cultural relic shock isolation device are perpendicular to each other, namely in the working process, the upper shock absorption mechanism and the lower shock absorption mechanism are respectively responsible for processing the components of the earthquake action in the respective directions, for example, the upper shock absorption mechanism, when the upper shock absorption mechanism is subjected to the earthquake action in the movement direction, the panel 5 and the middle plate 6 (also can be the bottom plate 7 of the upper shock absorption mechanism) move relatively under the action of inertia force to buffer the earthquake impact. In the process, the damper shearing part 401 and the damping fluid container 402 also move relatively, the lower end plate of the damper shearing part 401 does shearing motion in the damping fluid to generate damping force opposite to the motion direction, and kinetic energy is converted into heat energy to achieve the energy consumption effect.
Meanwhile, the moving parts 304 of the reset mechanism 3 also move relatively on the guiding cylindrical bars 302, wherein one moving part 304 increases the compression amount of the corresponding compression spring 303 in the moving process, on the other hand, the other moving part 304 on the same guiding cylindrical bar 302 reduces the compression amount of the corresponding compression spring 303, and when the moving distance reaches a certain value, the compression spring 303 is in a completely relaxed state. The restoring mechanism 3 provides restoring force to the cultural relic vibration isolation device by forming the difference of the compression spring 303 force through the different compression amount of the compression springs 303 at the two ends, and when the compression spring 303 at one side is in a completely relaxed state, the restoring force is provided by the compression spring 303 at the other side.
The function of the buffer 305 is that when the relative displacement exceeds a certain value, the buffer 305 on the moving element 304 is in a disengaged state with the compression spring 303. The relative displacement is gradually reduced by the restoring force, and the buffer pad 305 on the moving member 304 again contacts and compresses the compression spring 303, and in the process, the buffer pad 305 can relieve the impact when the compression spring 303 is contacted again.
In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
