Description

Technical Field

[0001] The present invention belongs to the technical field of cultural relics safety protection devices, and in particular, relates to a cultural relic cabinet with three-dimensional seismic isolation and cultural relic anti-overturning protection functions, which is applied to the field of storage cultural relics protection. Technical Background

[0002] At present, most of the cultural relics in the collection are placed in the cabinets by floating, and few cabinets and the cultural relics in the cabinets are seismically isolated. And the cultural relics generally have the attribute of being historical and cultural heritage and cannot be replicated. Therefore, when an earthquake occurs, it is urgent to reduce the damage of the earthquake to the movable collection of cultural relics that carry a wide range of cultural history and artistic heritage, are large in number, and are difficult to protect.

[0003] According to the existing storage cabinets and the placement of cultural relics in the cabinets, most of the storage cultural relics have not taken any shock-absorbing and seismic isolation measures, and some fragile cultural relics are even placed on wooden shelves without any protection measures. When an earthquake occurs, the storage cabinets and the cultural relics in the cabinets will shake or slip, and may fall out of the cabinets. In high-magnitude areas, the cabinets may even overturn, which makes the cabinets and the cultural relics in the cabinets extremely vulnerable to earthquakes. Such cabinets usually need to be replaced with seismic isolation cabinets.

[0004] Due to the rarity of cultural relics, the places where they are stored and the shock-absorbing and isolating devices should not produce toxic and harmful gases and liquids to avoid polluting the environment in the warehouse and damaging the cultural relics; the dampers and connectors have good durability and need to remain intact and in working condition for a long time; when designing shock-absorbing brackets and connectors, it is necessary to ensure that the cultural relic cabinets are not punched or glue is used, which may damage the cabinets. At the same time, the construction should be simple and fast to minimize interference with the warehouse environment.

[0005] Existing cultural relic cabinets (such as those with authorization publication numbers CN112971461B and CN112932206B) are mostly designed for exhibition-type cultural relics. However, in fact, the number of cultural relics in storage is far greater than that of cultural relics on display. Taking the Forbidden City as an example, cultural relics on display only account for 2% of the cultural relics collection. A large number of cultural relics in storage have suffered heavy losses in previous earthquakes due to the lack of effective protection. For example, the 2013 Lushan earthquake caused damage to museums and cultural management offices in the affected areas, more than 100 cultural relics protection units were affected, and nearly 300 cultural relics in the collection were damaged. It can be seen that it is more important to provide protection for cultural relics in storage. Summary of the invention

[0006] Due to the above technical problems currently existing, the technical problem to be solved by the present invention is to provide a cultural relic cabinet with three-dimensional seismic isolation and cultural relic anti-overturning protection functions.

[0007] To achieve the above object, the present invention adopts the following scheme:

[0008] Since most of the cultural relics cabinets in storage and the cultural relics in the cabinets are not equipped with any shock-absorbing and seismic isolation measures, the related technical problem to be solved by the present invention is to provide a cultural relics cabinet with three-dimensional seismic isolation and cultural relics anti-overturning protection functions. The present invention protects the cultural relics in the cabinet in stages according to the order in which the earthquake waves arrive. In addition, the present invention can connect the cultural relics cabinets into a group of cultural relics cabinets to jointly resist the effects of earthquakes, thereby achieving better protection effects on the cultural relics in storage.

[0009] A cultural relic cabinet with three-dimensional seismic isolation and cultural relic anti-overturning protection functions, comprising: a cultural relic cabinet body connection device 1, a threaded galvanized pipe 2 that can be spliced, a shock-absorbing and supporting device 3 at the bottom of the cultural relic cabinet, a cultural relic box base 4 with a shock-absorbing function, and a cultural relic cabinet body 5.

[0010] Compared with the prior art, the present invention has the following advantages and effects:

[0011] 1. The present invention sets three lines of defense according to the order of arrival of seismic waves. After the longitudinal wave reaches the surface, the shock-absorbing and supporting device at the bottom of the cultural relic cabinet first provides vertical protection for the cultural relics; then the transverse wave, the cultural relic box base with shock-absorbing function and the shock-absorbing and supporting device at the bottom of the cultural relic cabinet cooperate to protect the cultural relic cabinet and the cultural relics in the cabinet; finally, the body wave and the surface wave, the cultural relics in the cabinet are strengthened through the cultural relic box base with shock-absorbing function inside the cultural relic cabinet.

[0012] 2. The cultural relic cabinets in the present invention can be connected by a cultural relic cabinet connecting device to form a "rigid body" to jointly resist earthquake effects.

[0013] 3. All devices in the present invention do not produce toxic and harmful gases and liquids, thus avoiding pollution of the environment in the warehouse and damage to cultural relics;

[0014] 4. When installing various devices, the cultural relics cabinets are not moved, holes are not drilled, glue is not used, and other technical methods are not used. The modular assembly method is used to ensure simple and fast construction, while reducing interference with the warehouse environment.

[0015] 5. The durability of the damper and connectors is good, meeting the requirements of not being damaged and being able to maintain working condition for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
