Description

Technical Field

[0001] The invention belongs to the technical field of shockproof devices, and in particular relates to a shockproof base for cultural relics used in museums. Background Art

[0002] Cultural relics, as crucial vehicles for historical heritage and cultural research, are both irreplaceable and unique, holding an irreplaceable position in the development of spiritual civilization. As the primary venues for the preservation and display of cultural relics, museums have a core responsibility to ensure their safety and integrity.

[0003] Currently, the mainstream fixing methods are wire bolts and brackets. Wire bolts use thin wires to secure the narrow neck of an artifact to the four corners of the display case, while brackets secure the artifact between multiple brackets. However, natural disasters such as earthquakes pose a serious threat to the safety of museum artifacts, and both methods still have drawbacks in terms of earthquake protection. With wire bolts, ordinary nylon wire has limited tension and can break in strong earthquakes. With brackets, gaps between the brackets and the artifact can cause the artifact to sway, and prolonged vibration can damage the artifact's surface. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a shock-proof base for cultural relics for museums to solve the defects of the existing fixing method proposed in the background art.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a shock-proof base for cultural relics for museums, including tempered glass, a shock-absorbing mechanism and a main base. The shock-absorbing mechanism is arranged on the main base, and the tempered glass is arranged above the shock-absorbing mechanism. The tempered glass is used to display cultural relics and provide transparent protection; the shock-absorbing mechanism is the core shock-proof component, responsible for absorbing and dissipating earthquake energy; the main base provides a stable basic support for the entire base.

[0006] Furthermore, the shock-absorbing mechanism includes a structural base, a carrying frame, a skirt, a shock-proof system and a traction system. The structural base is fixedly connected to the main base, the carrying frame is arranged above the structural base, the skirt is fixedly connected to the side wall of the carrying frame, the traction system is arranged in the carrying frame, the shock-proof system is connected to the carrying frame, the structural base is connected to the main base and supports the upper structure; the carrying frame constitutes the main frame of the shock-absorbing mechanism and provides a layered installation platform; the skirt is used to shield the internal structure and beautify the appearance; the shock-proof system directly supports the cultural relics and provides the main passive shock-absorbing function; the traction system provides flexible constraints on the upper part of the cultural relics.

[0007] Furthermore, the carrying frame includes a bottom partition, a middle partition, a top partition, a lower pillar and an upper pillar. The bottom partition is fixed to the structural base through an inserted rod. The four corners of the bottom partition are fixed to the lower pillar. The middle partition is fixed to the top of the lower pillar. The four corners of the middle partition are fixed to the upper pillar. The top partition is fixed to the top of the upper pillar. A shock-absorbing pillar is provided in the middle of the bottom partition. The bottom of the bottom partition and the top of the structural base are both honeycomb steel structures. The honeycomb steel structure gives the bottom partition and the structural base excellent lightweight, high strength and energy dispersion capabilities, effectively absorbing and dispersing impact force.

[0008] Furthermore, the traction system includes a top connecting piece, a top ring, a top wheel, a bottom ring, a bottom wheel and a bottom connecting piece, the top connecting piece is threadedly connected to the middle partition, the bottom connecting piece is threadedly connected to the bottom partition, the top ring is connected to the top connecting piece, the top wheel is rotatably arranged in the top ring, the lower end of the bottom ring is connected to the bottom connecting piece, and the bottom wheel is arranged in the bottom ring.

[0009] Furthermore, the top connecting member and the bottom connecting member have the same working principle. The top connecting member includes a fixed joint, a damping spring, a connecting rod and an anti-vibration hammer. The fixed joint is threadedly connected to the middle partition, and the connecting rod is slidingly connected to the fixed joint. One end of the damping spring is fixed to the fixed joint, and the other end of the damping spring is fixed to the connecting rod. The anti-vibration hammer is arranged on the connecting rod. The damping spring absorbs longitudinal impact energy through compression / tensile deformation to buffer vibration; the connecting rod transmits tension and is installed with the anti-vibration hammer; the anti-vibration hammer uses inertia to generate reverse vibration opposite to the vibration direction, effectively offsetting lateral vibration energy, preventing the flexible connecting line from breaking due to resonance or overload, and together with the damping spring to achieve "double energy dissipation".

[0010] Furthermore, the shockproof system includes a shock-absorbing outer cabin and a carrying platform. The shock-absorbing outer cabin is fixedly connected to the shock-absorbing pillar through an energy dissipation damper. The carrying platform is arranged on the top of the shock-absorbing outer cabin. Transition connectors are provided at the four corners of the carrying platform.

[0011] Furthermore, the transition connector includes a transition spring, a transition channel and a transition connecting rod. The transition channel is fixedly connected to the mounting platform, the transition connecting rod is slidingly connected to the transition channel, one end of the transition spring is connected to the transition connecting rod, and the other end of the transition spring is connected to the transition channel.

[0012] Furthermore, a damping pendulum is movably connected to the bottom of the carrying platform, and a magnetic pole is connected to the bottom of the damping pendulum. A damping magnet is provided on the inner wall of the shock-absorbing outer cabin. The damping pendulum uses its inertia to swing in the opposite direction of the vibration during horizontal vibration, thereby offsetting the horizontal vibration energy. When the damping magnet is installed, the N pole of the damping magnet is set toward the center of the inner side of the shock-absorbing outer cabin, and the lower end (N extreme end) of the magnetic pole of the damping pendulum is set downward. When the magnetic pole swings with the damping pendulum, the damping magnet and the magnetic pole generate mutually repulsive magnetic fields to form magnetic damping, which actively suppresses the swing amplitude of the pendulum, prevents it from swinging excessively due to resonance and hitting the cabin wall, and protects the cultural relics from violent shaking.

[0013] Furthermore, an electromagnetic lock is provided under the top partition. Under normal power supply state, the electromagnetic lock adsorbs and locks the carrying platform, providing rigid support to keep the cultural relics stable; when an earthquake causes a power outage, it is automatically unlocked, allowing the carrying platform to instantly break away from the constraints of the top partition and switch to a flexible shock absorption mode jointly acted by the lower shockproof system and traction system, to prevent the earthquake energy from being directly transmitted through the rigid connection to damage the cultural relics.

[0014] Furthermore, the outer corner of the shock-absorbing outer cabin is rotatably connected to the side rotating wheel, and the upper end of the bottom ring is rotatably connected to the traction line, which passes around the top rotating wheel, the bottom rotating wheel and the side rotating wheel in sequence, and the traction line is also fixed to the lower end of the transition connecting rod.

[0015] The beneficial effects of the museum cultural relic shockproof base provided by this solution are as follows: (1) A multi-level energy dissipation mechanism is adopted. Through the dual energy dissipation design of the damping spring and the anti-vibration hammer of the traction system, the earthquake impact energy is effectively absorbed. The damping spring buffers the longitudinal impact by deformation, and the anti-vibration hammer uses inertial reverse vibration to offset the lateral vibration, thereby reducing the risk of flexible connecting line breakage. (2) The bottom partition and structural base adopt honeycomb steel structure, which has both lightweight and high strength characteristics, improving the overall compression resistance and energy dispersion capacity of the base; (3) By combining a damping pendulum, a magnetic pole, and a damping magnet, the inertia of the pendulum is used to offset horizontal vibrations, while the repulsion of the magnetic poles actively suppresses the swing amplitude to avoid resonance damage to cultural relics. (4) When the power is off (triggered by an earthquake), the electromagnetic lock automatically releases the rigid connection between the carrying platform and the top partition, and instantly switches to a flexible shock absorption mode to avoid rigid conduction damage; (5) Through the traction line, linked side wheels, wheel group and transition connecting rod, the cultural relics can maintain multi-directional force balance during vibration and suppress the risk of overturning.

One end of the transition spring 227 is connected to the transition connecting rod 229, and the other end of the transition spring 227 is connected to the transition channel 228. A damping pendulum 230 is movably connected to the bottom of the carrying platform 225, and a magnetic pole 231 is connected to the bottom of the damping pendulum 230.

The upper end of the bottom collar 209 is rotatably connected to the traction line 212. The traction line 212 passes through the top wheel 208, the bottom wheel 210, and the side wheels 236 in sequence. The traction line 212 is also fixed to the lower end of the transition link 229.

[0023] When in use, the cultural relic is first placed on the carrying platform 225, and then the thin neck of the cultural relic and the transition connecting rods 229 at the four corners are connected by flexible connecting lines. The top connecting piece 206 and the bottom connecting piece 211 are rotated to make the top connecting piece 206 and the bottom connecting piece 211 approach the middle partition 218 and the bottom partition 217 respectively. The traction line 212 is tightened as a whole, and the tempered glass 1 is closed to complete the installation of the cultural relic. The traction system 205 is used to provide traction to the top of the cultural relic, and the anti-seismic system 204 provides support for the cultural relic. When an earthquake occurs, the electromagnetic lock 234 is powered off, and the electromagnetic lock 234 stops adsorbing the carrying The platform 225 is separated from the top partition 219. The impact energy is first transmitted to the main base 3, and then transmitted to the top connector 206 by the main base 3. Affected by the impact energy, the top connector 206 and the carrying frame 202 keep synchronous vibration. When the impact energy is transmitted to the carrying frame 202; the top connector 206 and the bottom connector 211 absorb the impact energy transmitted to the traction system 205. The top connector 206 and the bottom connector 211 have the same working principle. The impact energy is transmitted to the fixed joint 213, and the fixed joint 213 vibrates and squeezes the damping spring 214. The damping spring The spring 214 is squeezed and shortened by the fixed joint 213, and the deformation of the damping spring 214 is used to absorb the impact energy. When the impact energy is transmitted to the connecting rod 215 and the connecting rod 215 vibrates, the anti-vibration hammer 216 will vibrate in the opposite direction to the connecting rod 215 due to inertia, thereby offsetting the impact energy transmitted to the connecting rod 215. The damping spring 214 and the anti-vibration hammer 216 offset the impact energy transmitted to the traction system 205, which can ensure that the traction line 212 is balanced and avoids breakage. In addition, when the impact energy is transmitted to the bottom partition 217, the shock absorbing pillar 223 is subjected to the transmitted impact energy, and the shock absorbing outer cabin The impact energy is offset between 224 and the shock-absorbing strut 223 through the energy dissipation damper 233. At the same time, the horizontal impact energy transmitted to the shock-absorbing outer capsule 224 is transmitted to the damping pendulum 230. The damping pendulum 230 swings under the influence of inertia. The swing direction of the damping pendulum 230 is opposite to the vibration direction (horizontal vibration) of the shock-absorbing outer capsule 224. During the swinging process of the damping pendulum 230, the repulsive force of the damping magnet 232 on the magnetic pole 231 is used to reduce the swing amplitude of the damping pendulum 230, thereby preventing the swing amplitude of the damping pendulum 230 from increasing, thereby causing the damping pendulum 230 to hit the shock-absorbing outer capsule 224.
