Description

Technical Field

[0001] The present invention relates to the technical field of earthquake protection and equipment vibration isolation, and specifically to a three-dimensional intelligent vibration isolation platen system based on earthquake early warning. Background Art

[0002] An earthquake, also known as ground motion or ground vibration, is a natural phenomenon in which vibrations are caused during the rapid release of energy in the earth's crust, during which seismic waves are generated. The mutual extrusion and collision between plates on the earth cause dislocation and rupture at the edges and within the plates, which is the main cause of earthquakes. The location where an earthquake begins is called the hypocenter, and the ground directly above the hypocenter is called the epicenter. The area with the most intense ground vibration during a destructive earthquake is called the meizoseismal area, which is often the area where the epicenter is located. Earthquakes often cause serious casualties, can trigger fires, floods, leakage of toxic gases, diffusion of bacteria and radioactive substances, and may also cause secondary disasters such as tsunamis, landslides, collapses, and ground fissures.

[0003] Existing large-scale supercomputers, as the core equipment for high-performance computing, have extremely high requirements for the operating environment. In traditional computer vibration isolation equipment, most adopt passive vibration isolation methods. The passive vibration isolation system cannot perceive the occurrence of an earthquake in advance and can only start to play a vibration isolation role when seismic waves reach the equipment. Since the propagation speed of seismic waves is relatively fast, when the equipment senses the vibration, the seismic waves may have already caused an initial impact on the equipment. Therefore, a three-dimensional intelligent vibration isolation platen system based on earthquake early warning is proposed. Summary of the Invention

[0005] To achieve the above purpose, the present invention provides the following technical solution: A three-dimensional intelligent vibration isolation platen system based on earthquake early warning, including a wireless vibration sensor, an earthquake early warning module, and a control module;

[0006] The wireless vibration sensor is used to monitor the ground vibration situation in real time;

[0007] The earthquake early warning module is used to receive the vibration data from the wireless vibration sensor. After judging that an earthquake is about to occur, the earthquake early warning module sends a warning signal to the control module;

[0008] The control module is used to adjust the working height of the support plate according to the instructions of the earthquake early warning module;

[0009] A computer is provided on one side of the wireless vibration sensor, and a support plate is installed at the bottom of the computer;

[0016] Preferably, baffles are fixed around the top of the bottom plate, and a sliding rod inserted into one side of the sliding block is fixed between one side of the baffle and the fixing frame.

[0022] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0023] 1. After the earthquake early warning module receives the vibration signal detected by the wireless vibration sensor, it can quickly send an early warning signal to the control module, enabling the hydraulic cylinder to start working in time, gaining time for subsequent earthquake prevention measures, and making protective preparations before the seismic wave reaches the computer equipment, effectively reducing the risk of damage to the computer caused by the earthquake.

[0024] 2. Horizontally, the sliding table slides within the sliding groove, causing the first spring to undergo elastic deformation. Through the combination of sliding and elastic deformation, the vibration energy in the horizontal direction can be absorbed, reducing the impact of horizontal vibration on the computer.

[0037] Embodiment

[0038] Please refer to Figure 1-8 , the present invention provides a technical solution: a three-dimensional intelligent vibration isolation table board system based on earthquake early warning, including a wireless vibration sensor 8, an earthquake early warning module and a control module;

[0039] The wireless vibration sensor 8 is used to monitor the ground vibration situation in real time;

[0040] The earthquake early warning module is used to receive the vibration data from the wireless vibration sensor 8. After judging that an earthquake is about to occur, the earthquake early warning module sends a warning signal to the control module;

[0041] The control module is used to adjust the working height of the support plate 2 according to the instruction of the earthquake early warning module;

[0042] The wireless vibration sensor 8 is connected to the earthquake early warning module, and the earthquake early warning module is connected to the control module. One side of the bottom of the wireless vibration sensor 8 is installed on one side of the top of the support plate 2. The number of the support columns 4 and the hydraulic cylinders 5 is four each. The support columns 4 and the hydraulic cylinders 5 are arranged at intervals, and a support beam 3 is fixed to the bottom of the support plate 2.

[0043] On one side of the wireless vibration sensor 8, there is a computer 1, and a support plate 2 is installed at the bottom of the computer 1; at the bottom of the support plate 2, there are respectively a support column 4 and a hydraulic cylinder 5; at the push rod end of the hydraulic cylinder 5, there is a buffer assembly 6 for isolating vibration of the computer 1 during an earthquake;

[0044] The buffer assembly 6 includes a bottom plate 61. At the center of the top of the bottom plate 61, a fixing frame 615 is fixed. At the top of the fixing frame 615, there is a top plate 64 located below the support plate 2. On one side of the bottom plate 61, there are four chutes 67 opened. Inside the chutes 67, a sliding table 66 is slidably connected. At the top of the sliding table 66, a slider 65 is fixed.

[0045] Around the top of the bottom plate 61, baffles 62 are fixed. Between one side of the baffle 62 and the fixing frame 615, a slide rod 63 inserted into one side of the slider 65 is fixed. Outside the slide rod 63, a first spring 68 is sleeved. The two sides of the first spring 68 are respectively connected to one side of the slider 65 and the fixing frame 615. The first spring 68 is used to transmit, absorb, and consume the vibration energy transmitted by the upper structure. The vibration generated on the ground is transmitted to the buffer assembly 6 through the support column 4. In the horizontal direction, the sliding table 66 slides in the chute 67, and the first spring 68 undergoes elastic deformation to absorb the vibration energy in the horizontal direction; in the vertical direction, the shock absorber 610 and the second spring 611 work together to absorb the vibration energy in the vertical direction, thereby reducing the impact of the earthquake on the computer 1 and protecting the safety of the computer 1.

[0046] On one side of the top of the four sliders 65, three first connecting rods 69 are ball-jointed. On one side of the first connecting rods 69, a second limiting plate 614 is fixed. On one side of the top of the second limiting plate 614, a shock absorber 610 is installed. The number of shock absorbers 610 is 12, which is used to enhance the load-bearing capacity in the horizontal direction and achieve shock absorption through the combined action of elastic deformation energy storage, damping energy dissipation, and mechanical limiting. One end of the top of the shock absorber 610 is fixed with a first limiting plate 613. On one side of the top of the first limiting plate 613, a second connecting rod 612 ball-jointed to the bottom side of the top plate 64 is fixed; through the combined action of the sliding table 66, the slider 65, the first spring 68, the shock absorber 610, and the second spring 611, the buffer assembly 6 can absorb the vibration energy in both horizontal and vertical directions simultaneously, providing more comprehensive vibration isolation protection.

[0047] Outside the shock absorber 610, a second spring 611 is sleeved. The two sides of the second spring 611 are respectively connected to one side of the first limiting plate 613 and the second limiting plate 614. The bottom of the bottom plate 61 is fixed to the push rod end of the hydraulic cylinder 5. The bottom plate 61 is located at the bottom of the support plate 2. When the wireless vibration sensor 8 does not receive a vibration signal, the push rod end of the hydraulic cylinder 5 retracts, so that the bottom of the support plate 2 contacts the top of the support column 4, and the support column 4 supports the computer 1 and the support plate 2 at its bottom.

[0048] Working principle: When the earthquake early warning module receives the vibration signal detected by the wireless vibration sensor 8, the earthquake early warning module sends an early warning signal to the control module, causing the hydraulic cylinder 5 to receive the signal from the control module and start working, jacking up the support plate 2 and the support beam 3, so that the bottom of the support plate 2 leaves the top of the support column 4, and making the buffer assembly 6 fit against the bottom of the support plate 2; it can sense the earthquake in advance and send out an early warning signal, actively adjust the working height of the support plate 2, and make the buffer assembly 6 get ready in advance, improving the initiative and effectiveness of vibration isolation.

[0049] When an earthquake occurs, the vibration generated on the ground is transmitted to the buffer assembly 6 through the support column 4. In the horizontal direction, the sliding table 66 slides in the sliding groove 67, and the first spring 68 undergoes elastic deformation to absorb the vibration energy in the horizontal direction; in the vertical direction, the shock absorber 610 and the second spring 611 work together to absorb the vibration energy in the vertical direction, thereby reducing the impact of the earthquake on the computer 1 and protecting the safety of the computer 1. Through the coordinated action of the sliding table 66, the sliding block 65, the first spring 68, the shock absorber 610 and the second spring 611, the buffer assembly 6 can absorb the vibration energy in both the horizontal and vertical directions simultaneously, providing more comprehensive vibration isolation protection.

[0050] When the wireless vibration sensor 8 does not receive the vibration signal, the push rod end of the hydraulic cylinder 5 retracts, causing the bottom of the support plate 2 to contact the top of the support column 4. The support column 4 supports the computer 1 and the support plate 2 at its bottom. At the same time, the top plate 64 leaves the bottom of the support plate 2. The support plate 2 is supported by the support column 4 or the hydraulic cylinder 5, and reinforced by the support beam 3, providing a stable support structure for the computer 1 and ensuring the reliability of the system.

[0051] When the wireless vibration sensor 8 does not receive the vibration signal, the push rod end of the hydraulic cylinder 5 retracts, and the bottom of the support plate 2 re - contacts the top of the support column 4. The support column 4 resumes its supporting role for the computer 1 and the support plate 2 at its bottom, ensuring that the computer 1 can be stably placed under normal conditions and maintaining its normal working environment. Subsequently, the top plate 64 leaves the bottom of the support plate 2, enabling the buffer assembly 6 to return to its initial state, preparing for the next earthquake early warning and protection, ensuring that the entire earthquake - proof system can be recycled and improving the reliability of the system.

[0052] In summary, after the earthquake early warning module receives the vibration signal detected by the wireless vibration sensor 8, it can quickly send an early warning signal to the control module, causing the hydraulic cylinder 5 to start working in a timely manner, gaining time for subsequent earthquake - proof measures, making protective preparations before the seismic wave reaches the computer 1 device, and effectively reducing the risk of damage to the computer 1 caused by the earthquake.

[0053] In the horizontal direction, the slide table 66 slides within the chute 67, causing the first spring 68 to undergo elastic deformation. Through the combination of sliding and elastic deformation, the vibration energy in the horizontal direction can be absorbed, reducing the impact of horizontal vibrations on the computer 1. In the vertical direction, the shock absorber 610 and the second spring 611 work together. The shock absorber 610 can absorb and dissipate vibration energy through its own damping characteristics, while the second spring 611 further buffers the impact force in the vertical direction using its elastic deformation. The two cooperate with each other to effectively absorb the vibration energy in the vertical direction, protecting the computer 1 from seismic shocks in all directions. When an earthquake occurs, the bottom of the support plate 2 leaves the top of the support column 4, and the buffer assembly 6 fits against the bottom of the support plate 2, enabling the computer 1 to absorb vibration energy through the buffer assembly 6 during the earthquake and maintaining a relatively stable support state, preventing the computer 1 from toppling or being damaged due to severe vibrations.
