An earthquake protection device for preventing false touch on cultural relics and a use method thereof

Abstract

This invention discloses an earthquake protection device for preventing accidental contact with cultural relics and its usage method. The device includes a frame assembly, which comprises a shell with a top cover. An inertial block is located inside the shell, and multiple sets of bullseye bearings are movably mounted at the bottom of the inertial block. A slot is formed through the top of the top cover. The device is first installed inside a seismic isolation platform, where a stop pin locks the upper plate of the platform. During an earthquake, the inertial block shakes inside the shell, relying on the bullseye bearings. In this process, the inertial block impacts the rotational connection points of connecting rods one and two, and connecting rods one and three, causing connecting rod three to open. The spring force of spring two then moves the mechanism baffle, causing the stop pin to engage with the slot and trigger the vibration warning. This structure avoids accidental external contact that could cause the upper plate of the seismic isolation platform to shake, thus preventing false warning triggering and improving the stability of the warning trigger.

Description

Technical Field

[0001] This invention relates to the field of earthquake protection technology for cultural relics, and in particular to an earthquake protection device for preventing accidental contact with cultural relics and its usage method. Background Technology

[0002] Currently, specialized seismic isolation platforms are widely used in the field of earthquake protection for cultural relics to ensure their safety. These platforms consist of two main components: a rigid connection at the bottom to the ground to ensure overall structural stability, and a top that directly supports the relics. When external vibrations occur or the platform detects abnormal shaking, the system immediately triggers an early warning mechanism, notifying relevant personnel to take timely action. Furthermore, the seismic isolation platform possesses excellent vibration reduction and stability performance. Even under external disturbances, the area on top supporting the relics will not experience large-scale or violent shaking, effectively preventing damage or displacement of the relics caused by vibration. This dual protection mechanism, combining real-time early warning and physical seismic isolation, significantly enhances the safety and stability of cultural relics during storage, providing more reliable technical protection for precious cultural heritage.

[0003] However, when visitors or staff accidentally touch the load-bearing platform, causing it to shake, the existing seismic isolation platform will also trigger the alarm mechanism, leading to several problems: First, there is a risk of false triggering; accidental touching of the artifact placement platform can easily trigger a false alarm, resulting in a decrease in the overall reliability of the system. Second, the earthquake protection mechanism has limitations; traditional devices mostly rely on a single sensor for vibration detection, making it difficult to effectively distinguish between vibrations caused by human touch and strong vibrations caused by an earthquake. During an earthquake, response delays or misjudgments may cause the artifact protection function to fail. Third, the reset mechanism lacks security; some devices equipped with automatic reset functions can be reset arbitrarily by unauthorized personnel, posing a security vulnerability. A touch-proof sliding pin device that can accurately distinguish between human touch and earthquake vibration and requires manual authorization for reset is needed to improve the reliability and safety of artifact protection. Therefore, designing an earthquake protection device to prevent accidental touch of artifacts and solve the above problems is particularly important. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an earthquake protection device for preventing accidental contact with cultural relics and a method of using it.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] An earthquake protection device to prevent accidental contact with cultural relics includes a frame assembly, the frame assembly including an outer shell, a top cover on the top of the outer shell, an inertial block inside the outer shell, multiple sets of bullseye bearings movably arranged at the bottom of the inertial block, a slot through the top of the top cover, and an early warning component inside the slot, the early warning component being used to provide warning during an earthquake.

[0007] An opening and closing component is provided inside the outer shell near the center of the inertial block. The opening and closing component is used to control the early warning component to issue an alarm.

[0008] A reset component is provided inside the upper cover near one side, and the reset component is used to control the reset of the warning component after the warning is issued.

[0009] The upper cover is provided with a control component, which is used to control the movement of the reset component.

[0010] According to the earthquake protection device for preventing accidental contact with cultural relics, the early warning component includes a second spring abutting against the bottom of the upper cover. The end of the second spring away from the upper cover abuts against a mechanism baffle. A stop pin is provided on the side of the mechanism baffle near the second spring, and the stop pin is movably disposed inside the slot.

[0011] According to the earthquake protection device for preventing accidental contact with cultural relics, the opening and closing component includes a base fixedly connected to the bottom of the inner side of the outer shell. The base has an inverted "T" shaped cross section. A linear sliding sleeve is movably arranged outside the base. Multiple sets of connecting rods are movably arranged outside the linear sliding sleeve. A connecting rod is movably arranged at the end of the connecting rod away from the linear sliding sleeve.

[0012] According to the earthquake protection device for preventing accidental contact with cultural relics, the connecting rods are arranged in a circular array in multiple groups. One of the connecting rods is movably connected to one end of the connecting rod three. The connecting rod three is movably provided with a connecting rod fixing plate near the position of the connecting rod one. The connecting rod fixing plate is located outside the base.

[0013] According to the earthquake protection device for preventing accidental contact with cultural relics, another part of the connecting rod one is movably provided with a connecting rod two at the end away from the linear sliding sleeve, and the end of the connecting rod two away from the connecting rod one is movably provided outside the connecting rod fixing plate. A spring one is fixedly connected between the linear sliding sleeve and the base.

[0014] According to the earthquake protection device for preventing accidental contact with cultural relics, the reset component includes a push block movably disposed inside the upper cover near the slot. The push block is U-shaped, and a sloping groove is provided inside the push block near the center of the upper cover. A pushing groove is provided on the side of the push block away from the center of the upper cover.

[0015] According to the earthquake protection device for preventing accidental contact with cultural relics, the control component includes a plunger pin, a plunger sleeve is movably disposed outside the plunger pin, and a spring is fixedly connected inside the plunger sleeve at a position opposite to the plunger pin.

[0016] According to the earthquake protection device for preventing accidental contact with cultural relics, the upper cover is provided with a reset component two. The reset component two includes a sliding groove opened inside the upper cover near the push block. A spring four is provided on the side of the push block opposite to the sliding groove.

[0017] According to the earthquake protection device for preventing accidental contact with cultural relics, the third connecting rod is arranged with an "L"-shaped opening at the end away from the first connecting rod and near the connecting rod fixing plate.

[0018] A method for preventing accidental touches specifically includes the following steps:

[0019] S1. The outer shell needs to be installed between the seismic isolation platforms first. When an earthquake occurs and causes shaking, the outer shell shakes synchronously with the artifact shelf. The inertial block inside the outer shell is displaced by the bottom bullseye bearing. After the inertial block is displaced, it will trigger the opening and closing component, causing the warning component controlled by the opening and closing component to move down, thereby unlocking the seismic isolation platform.

[0020] S2. When the inertial block moves and shakes, it will impact the rotating connection between connecting rod 1 and connecting rod 3, causing the end of connecting rod 1 near the linear sliding sleeve to rotate, which in turn causes connecting rod 3 to rotate around the connecting rod fixing plate and open. After connecting rod 3 opens, spring 2 will push the mechanism baffle down at the bottom of the upper cover, which will then cause the stop pin to slide along the inside of the groove. The stop pin will then disengage from the top plate of the vibration isolation platform, thus enabling the vibration isolation platform to achieve the effects of alarm and protection of cultural relics.

[0021] S3. When the connecting rod is open, the connecting rod one can form a rotatable connection with the connecting rod fixing plate through the connecting rod two, which ensures the structural stability of the connecting rod fixing plate and the linear sliding sleeve during displacement, and provides a guarantee for the reset operation in the subsequent use stage of the device.

[0022] S4. When resetting, insert the plunger pin along the outside of the upper cover near the push block. The spring three inside the plunger sleeve pushes the plunger pin so that it is embedded in the push groove. Then the plunger pin drives the push block to slide along the inside of the upper cover, lifting the stop pin embedded in the groove along the ramp groove, allowing the stop pin to reset, and then driving the mechanism baffle to compress the spring two.

[0023] S5. During the fourth step of the operation, the displaced push block will squeeze the spring four in the sliding groove, causing the spring four to contract. The push block slides into the sliding groove to complete the reset. After the plunger pin is removed from the top cover, the spring four will push the push block to complete the reset in the sliding groove.

[0024] S6. After the limit baffle is disengaged from the connecting rod three, the spring one drives the linear sliding sleeve to slide along the outside of the base. Then the linear sliding sleeve drives the connecting rod one, as well as the connecting rod two and connecting rod three which are rotatably connected to the connecting rod one to complete the reset. After that, the connecting rod three abuts against the limit baffle through its own groove to ensure that the stop pin has extended from the groove position.

[0025] The above-mentioned solution has the following beneficial effects:

[0026] 1. First, install the device inside the seismic isolation platform, allowing the stop pin to lock the upper plate of the seismic isolation platform. When an earthquake occurs, the inertial block can shake inside the outer shell by relying on the bullseye bearing. During this process, the inertial block can strike the rotational connection position of connecting rod 1 and connecting rod 2, and connecting rod 1 and connecting rod 3, causing connecting rod 3 to open. Then, the elastic force of spring 2 can drive the mechanism baffle to move, allowing the stop pin to be embedded in the slot to complete the vibration warning trigger. This structure can avoid the problem of the upper plate of the seismic isolation platform shaking due to external accidental contact, thus improving the stability of the warning trigger.

[0027] 2. After the early warning mechanism is triggered, the system achieves a coordinated response of key components through the sliding of the push block: When the push block slides along the predetermined motion trajectory, guided by the structure of the inclined slide, the stop pin is smoothly pushed out of its embedded slot by the component force generated by the inclined surface. During this process, the stop pin moves and compresses the second spring, allowing it to accumulate elastic potential energy. As the stop pin continues to move, it drives the connected mechanism baffle to move synchronously, causing the mechanism baffle to disengage from the limiting area of ​​the linkage three. After the mechanism baffle disengages from the limit, the originally constrained spring one releases the stored elastic potential energy, causing the linear slide sleeve to quickly reset to the initial position, and allowing the stop pin to lock the upper plate of the vibration isolation platform again, completing the automatic reset process of the mechanism. After the reset is completed, the linkage three, through the slotted structure set at the top, re-forms an effective constraint and positioning of the mechanism baffle, restoring the entire early warning device to a ready state that can be triggered again. This coherent and precise mechanical action process not only ensures the timely response of the early warning function, but also significantly improves the reset reliability and reusability of the early warning device during multiple uses.

[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0049] Continue reading Figure 7 The upper cover 12 is provided with a reset component 2 6. The reset component 2 6 includes a sliding groove 61 opened inside the upper cover 12 near the push block 41. A spring 4 62 is provided on the side opposite to the push block 41 and the sliding groove 61.

[0050] One method to prevent accidental touches, such as Figure 9 As shown, the specific steps include:

[0051] S1. The outer shell 11 needs to be installed between the seismic isolation platforms first. When an earthquake occurs and causes shaking, the outer shell 11 shakes synchronously with the artifact shelf. The inertial block 13 inside the outer shell 11 is displaced by the bottom bullseye bearing 14. After the inertial block is displaced, it will trigger the opening and closing component 2, causing the warning component 3 controlled by the opening and closing component 2 to move down, thereby unlocking the seismic isolation platform.

[0052] When the inertial block 13 moves and vibrates, it will impact the rotating connection between the first connecting rod 24 and the third connecting rod 27, causing the end of the first connecting rod 24 near the linear sliding sleeve 23 to rotate, which in turn causes the third connecting rod 27 to rotate around the connecting rod fixing plate 26 and open. After the third connecting rod 27 opens, the second spring 32 will push the mechanism baffle 31 down at the bottom of the upper cover 12, which will cause the stop pin 33 to slide along the inside of the slot 15. The stop pin 33 will then disengage from the top plate of the vibration isolation platform, so that the vibration isolation platform can achieve the effects of alarm and protection of cultural relics.

[0053] S3. When the third connecting rod 27 is opened, the first connecting rod 24 can be rotatably connected to the connecting rod fixing plate 26 through the second connecting rod 25, which ensures the structural stability of the connecting rod fixing plate 26 and the linear sliding sleeve 23 during displacement, and provides a guarantee for the reset operation in the subsequent use stage of the device.

[0054] S4. When resetting, insert the plunger pin 51 along the outside of the upper cover 12 near the push block 41. The spring 3 53 inside the plunger sleeve 52 pushes the plunger pin 51 to embed it into the push groove 15. Then, the plunger pin 51 drives the push block 41 to slide along the inside of the upper cover, lifting the stop pin 33 embedded in the groove along the inclined slide groove 42, allowing the stop pin 33 to reset, thereby driving the mechanism baffle 31 to compress the spring 2 32.

[0055] S5. During the fourth step of the operation, the displaced push block 41 will squeeze the spring 62 in the sliding groove 61, causing the spring 62 to contract. The push block 41 will slide into the sliding groove 61 to complete the reset. After the plunger pin 51 is removed from the upper cover 12, the spring 62 will push the push block 41 to complete the reset in the sliding groove 61.

[0056] S6. After the limiting baffle 31 disengages from the connecting rod 27, the spring 22 drives the linear sliding sleeve 23 to slide along the outside of the base 21. Then the linear sliding sleeve 23 drives the connecting rod 24, the connecting rod 25 and the connecting rod 27 which are rotatably connected to the connecting rod 24 to complete the reset. After that, the connecting rod 27 abuts against the limiting baffle 31 through its own groove to ensure that the stop pin 33 has extended from the groove 15.

[0057] Working principle: First, during the usage phase, the outer shell 11 must be securely installed between the upper and lower plates of the seismic isolation platform, and the stop pin 33 should be embedded inside the upper plate. When an earthquake occurs, causing the ground and the artifact shelf to shake, since the outer shell 11 is rigidly connected to the artifact shelf, it will move or swing synchronously with the artifact shelf. The inertial block 13 set inside the outer shell 11 tends to maintain its original static or moving state under the action of inertia and will not move synchronously with the outer shell 11 immediately. At this time, the inertial block 13 can slide or roll relative to the outer shell 11 through the bullseye bearing 14 configured at the bottom, effectively reducing frictional resistance, so that the inertial block 13 can respond sensitively to the small vibrations caused by the earthquake. When the inertial block 13 generates a displacement inside the outer shell 11 that meets the triggering conditions, it will touch or drive the opening and closing component 2 linked with it. After the opening and closing component 2 is activated, it will further drive the early warning component 3 mechanically connected to it, so that the early warning component 3 moves quickly from the initial high position to the preset low position, thereby unlocking the upper plate of the seismic isolation platform, realizing the functions of earthquake early warning and artifact protection.

[0058] In the second step, when the inertial block 13 is displaced by external vibration, its motion will directly impact the rotating connection between connecting rod 1 24 and connecting rod 3 27. This impact will push the end of connecting rod 1 24 near the linear sleeve 23 to rotate around the connection point. At the same time, since connecting rod 3 27 is connected to the connecting rod fixing plate 26 through a rotating joint, under the drive of connecting rod 1 24, connecting rod 3 27 will open outward. During the opening process of connecting rod 3 27, its structural change will further act on spring 2 32, causing spring 2 32 to generate at the bottom of the upper cover 12. The downward thrust pushes the mechanism baffle 31 to move downward in the vertical direction; the downward movement of the mechanism baffle 31 will drive the stop pin 33 linked with it to move synchronously, causing the stop pin 33 to slide along the pre-set slot 15 of the shell to complete the sliding displacement. After the above series of mechanical linkage processes, the initial sway of the inertial block 13 caused by the earthquake is finally converted into a significant displacement change of the stop pin 33. The stop pin 33 will disengage from the upper plate positioning position of the seismic isolation platform, thereby unlocking the seismic isolation platform to perform its protective function and triggering the earthquake early warning signal.

[0059] Third, during the opening of link 3 27, link 1 24 always maintains effective linkage through the rotational connection structure between link 2 25 and link fixing plate 26. This rotational connection method not only ensures the coordination of relative motion between the links, but also significantly improves the stability and reliability of the entire mechanism when link fixing plate 26 and linear sliding sleeve 23 undergo synchronous displacement. When the device completes one work cycle and needs to be put into use again, the operator can perform a reset operation to restore the device to the initial ready position, ensuring accurate execution of the next trigger action and maintaining the continuous operation of the system as a whole.

[0060] Fourth step, during reset, firstly, the plunger pin 51 is precisely inserted into the corresponding position of the push block 41 on the outside of the upper cover 12; after the plunger pin 51 is inserted, the spring 3 53 inside the plunger sleeve 52 will output a thrust based on its own elastic potential energy, pushing the plunger pin 51 forward, so that the plunger pin 51 is embedded in the push groove 43 of the push block 41. When the plunger pin 51 and the push groove 43 are engaged, the push block 41 will move smoothly along the preset sliding track inside the upper cover 12. During the sliding process of the push block 41, the inclined slide groove 42 on its structure contacts the stop pin 33 and applies an upward force, so that the stop pin 33, which was originally embedded in the groove 15, is gradually lifted along the inclined slide groove 42, completing the reset of the stop pin 33. After the above actions are completed, the reset stop pin 33 drives the connected mechanism baffle 31 to move synchronously, applying a compressive force to the spring 2 32 to keep it in a compressed state, preparing for the subsequent operation of the mechanism;

[0061] Fifth, when performing the fourth step, after the push block 41 begins to move, its structure will simultaneously apply pressure to the spring 62 inside the sliding groove 61, causing the spring 62 to be compressed and deformed. At the same time, since the push block 41 is a U-shaped structure, its two arms can be stably embedded in the sliding groove 61 and slide smoothly along the inner wall of the sliding groove 61 to reach the designated position in the groove. After all the actions in the reset stage are completed, the plunger pin 51, which was originally limited inside the upper cover 12, can be released and removed. At this time, the spring 62 has accumulated elastic potential energy due to the previous compression. After losing external constraints, it will generate a reverse thrust inside the sliding groove 61, actively pushing the U-shaped push block 41 back to the initial position along the original path, realizing the automatic reset of the push block 41.

[0062] Finally, after the connection between the mechanism baffle 31 and the connecting rod 27 is completely disengaged, the spring 22, which is in a compressed state, will release the stored elastic potential energy and push the linear sleeve 23 connected to it to slide axially along the outer surface of the base 21. This sliding action causes the linear sleeve 23 to move, which in turn pulls the connecting rod 24, which is fixedly connected to the linear sleeve 23, to change position. Since the connecting rod 24 is connected to the connecting rod 25 and the connecting rod 27 respectively through a rotating joint, the entire linkage mechanism will gradually return to its initial state under the action of the spring force. After the reset process is completed, the guide groove structure on the connecting rod 27 will accurately abut against the corresponding position of the mechanism baffle 31 to form a stable mechanical limit. This structure not only ensures the positioning accuracy of the entire linkage mechanism, but also ensures that the stop pin 33 can smoothly and reliably extend completely from the slot 15 to effectively lock the relevant components or trigger the next working stage.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

10. A method for preventing accidental touches, using a cabinet stamping die as described in any one of claims 1-9, specifically comprising the following steps: S1. The outer shell (11) needs to be installed between the seismic isolation platforms first. When an earthquake occurs and causes shaking, the outer shell (11) shakes synchronously with the artifact shelf. The inertial block (13) inside the outer shell (11) is displaced by the bottom bullseye bearing (14). After the inertial block is displaced, it will trigger the opening and closing component (2), causing the warning component (3) controlled by the opening and closing component (2) to move down, thereby unlocking the seismic isolation platform. S2. When the inertial block (13) is displaced and shakes, it will hit the rotating connection between the first link (24) and the third link (27), causing the first link (24) to rotate near the end of the linear sliding sleeve (23), which in turn causes the third link (27) to rotate around the link fixing plate (26) and open. After the third link (27) opens, the second spring (32) will push the mechanism baffle (31) down at the bottom of the upper cover (12), which will cause the stop pin (33) to slide along the inside of the slot (15). The stop pin (33) will disengage from the top plate of the vibration isolation platform, so that the vibration isolation platform can achieve the effects of alarm and protection of cultural relics. S3. When the third link (27) is opened, the first link (24) can be rotated to the second link (25) and the link fixing plate (26) to ensure the structural stability of the link fixing plate (26) and the linear sliding sleeve (23) during displacement, and provide a guarantee for the reset operation in the subsequent use stage of the device. S4. When resetting, insert the plunger pin (51) along the outside of the upper cover (12) near the push block (41). The spring three (53) inside the plunger sleeve (52) pushes the plunger pin (51) so that it is embedded in the push groove (15). Then the plunger pin (51) drives the push block (41) to slide along the inside of the upper cover, lifting the stop pin (33) embedded in the groove along the ramp slide (42) so that the stop pin (33) is reset, thereby driving the mechanism baffle (31) to compress the spring two (32). S5. During the fourth step of the operation, the displacement push block (41) will squeeze the spring four (62) in the sliding groove (61), causing the spring four (62) to contract. The push block (41) will slide into the sliding groove (61) to complete the reset. After the plunger pin (51) is removed from the top cover (12), the spring four (62) will push the push block (41) to complete the reset in the sliding groove (61). S6. When the limiting baffle (31) disengages from the connecting rod three (27), the spring one (22) drives the linear slide sleeve (23) to slide along the outside of the base (21). Then the linear slide sleeve (23) drives the connecting rod one (24), and the connecting rod two (25) and connecting rod three (27) rotatably connected to the connecting rod one (24) to complete the reset. After that, the connecting rod three (27) abuts against the limiting baffle (31) through its own groove to ensure that the stop pin (33) has extended from the groove (15).
