Description

Technical Field

[0001] This invention relates to the field of seismic damping devices for buildings, specifically a novel damping device suitable for seismic resistance in buildings. Background Technology

[0002] Dampers are devices that provide resistance to motion and reduce the energy of motion. Various types of dampers have long been used in aerospace, aviation, military, gun and artillery, automobile and other industries to reduce vibration and dissipate energy. Since the 1970s, people have gradually applied these technologies to structural engineering such as buildings, bridges and railways, and their development has been very rapid.

[0003] Chinese patent CN209397759U discloses a building damper, including a horizontally arranged support plate. A cross-shaped magnetic isolation track is opened in the center of the support plate. Each of the four arm ends of the magnetic isolation track is equipped with a strip-shaped permanent magnet. Two parallel strip-shaped permanent magnets face each other with the same pole. A fixed seat is fitted on each strip-shaped permanent magnet. The outer side of the fixed seat is hinged to one end of a telescopic rod. The other end of the telescopic rod is fixedly connected to a horseshoe. A first ball joint support is installed on the other side of the horseshoe. The first ball joint support is located above the support plate. The outer side of the fixed seat is also hinged to one end of a compression spring. The other end of each compression spring is hinged to a bottom support through a second ball joint support. This damper provides uniform mechanical properties in all horizontal directions and can provide multi-directional damping for the structure. It can provide various resistance mechanisms such as shear and axial resistance. Moreover, it has a simple structure and low cost.

[0004] In actual use, the damper of the aforementioned patent only uses a telescopic rod and spring to buffer the impact force when reducing the vibration of the building. Its ability to reduce the impact force is poor, and the device has poor toughness in the process of reducing the impact force, making it easy to be damaged when subjected to a large instantaneous impact force. Summary of the Invention

[0005] The purpose of this invention is to provide a novel damper suitable for earthquake resistance in buildings. The invention involves a main extrusion plate compressing glycerin within a main glycerin storage chamber, a first secondary glycerin storage chamber, and a second secondary glycerin storage chamber. During this compression, the glycerin flows through buffer holes into the first and second secondary glycerin storage chambers, respectively, and then compresses the secondary extrusion plate. The buffer holes and secondary extrusion plate provide further buffering and damping effects. Furthermore, the buffer holes reduce the instantaneous pressure on the main extrusion plate, preventing damage to the device due to excessive instantaneous pressure.

[0016] Preferably, the data processing module calculates the swaying frequency and swaying force of the building exterior, including the following steps:

[0017] Step 1: Based on the rotation direction, frequency, and duration of the transmission gears, determine the sway acceleration of the building's exterior and construct the sway response equation for the building's exterior:

[0018] M*v+C*v+K*v=-M*Z;

[0019] Where M represents the mass diagonal matrix at different damping locations on the exterior of the building. m xy C represents the damped mass at coordinates (x, y); C represents the damping matrix. c xy This represents the damping coefficient at coordinates (x, y); K represents the external stiffness matrix of the building. k xy Z represents the building stiffness at the building's external location with damping at coordinates (x, y); Z represents the building sway matrix. h xy This represents the sway coordinates of the damper at its external position (x, y) on the building.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. This invention provides secondary damping medium storage frames at both the top and bottom of the main damping medium storage frame. Each secondary damping medium storage frame contains a secondary extrusion plate. A pair of buffer through-holes are located at both the top and bottom of the main damping medium storage frame. In actual use, glycerol is transferred from the building to the device and, through the main extrusion plate, extrudes the glycerol in the main storage chamber, the first secondary glycerol storage chamber, and the second secondary glycerol storage chamber. As the glycerol is extruded and flows through both ends of the main extrusion plate, it flows through the buffer through-holes into the first and second secondary glycerol storage chambers respectively. It then enters the first and second secondary glycerol storage chambers and extrudes the secondary extrusion plate. The buffer through-holes and secondary extrusion plates provide further buffering and damping effects. Furthermore, the buffer through-holes reduce the instantaneous pressure borne by the main extrusion plate, preventing damage to the device due to excessive instantaneous pressure.

[0031] 2. This invention features a first transmission rod at one end of a transmission roller. The first transmission rod has a receiving groove inside, and the receiving groove itself contains a transmission tooth groove. A transmission gear is located at the upper end of the transmission tooth groove. During actual use, as the main extrusion plate slides laterally within the main damping medium storage frame to dampen vibrations, the transmission roller adjusts its lateral position. This adjustment drives the transmission gear to rotate. The rotation is recorded by a rotation recording module, and the damping data is stored by a data storage module. This facilitates user operation and allows for the extraction and manual recording of the damper's usage frequency and process during subsequent maintenance. Based on the recorded usage frequency, consideration can be given to adding or removing dampers from the building to improve building safety. Furthermore, the damper can be maintained in equal amounts according to its usage frequency.

[0032] 3. This invention provides secondary damping medium storage frames at both the top and bottom of the main damping medium storage frame. A secondary extrusion plate is located in the middle of the secondary damping medium storage frame, and active return springs are located on both sides of the secondary extrusion plate. During actual damping, the lateral movement of the main extrusion plate actively pushes the glycerol inside the main glycerol storage chamber to flow into the first and second secondary glycerol storage chambers respectively. Flowing into the secondary damping medium storage frame adjusts the lateral position of the secondary extrusion plate. After the damper is used, the return springs push the secondary extrusion plate to reset, actively pushing the glycerol inside the secondary damping medium storage frame back into the main glycerol storage chamber and resetting the main extrusion plate.

[0045] To address the technical issues of existing dampers in practical use, which rely solely on telescopic rods and springs to buffer impact forces during building vibration reduction, resulting in poor impact mitigation capabilities and low device resilience, making them prone to damage under large instantaneous impacts, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides the following technical solution:

[0046] The main damping medium storage frame 10 has a glycerin main storage cavity 23 inside, and a main extrusion plate 29 inside the glycerin main storage cavity 23. The outside of the main extrusion plate 29 is connected to the internal slot of the main damping medium storage frame 10.

Buffer through holes 28 are provided at the upper and lower ends of both sides of the glycerin main storage cavity 23. The buffer through holes 28 penetrate the main damping medium storage frame 10 and extend into the interior of the first glycerin secondary storage cavity 24.

[0047] Specifically, the load-bearing capacity of the damper can be improved through the buffer through-hole 28, avoiding the load-bearing capacity relying solely on the damping effect of glycerin penetrating the main extrusion plate 29.

[0048] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides the following technical solution:

[0049] Sealing rings 12 are provided on both sides of the main damping medium storage frame 10. The sealing rings 12 are fixedly connected to the main damping medium storage frame 10 by bolts. A transmission rod 11 is provided on one side of the outer side of the sealing ring 12, and the transmission rod 11 is in a sealed sliding connection with the inside of the sealing ring 12. The transmission rod 11 is welded and fixed to the main extrusion plate 29. A first transmission rod 13 is provided at one end of the transmission rod 11.

[0050] Specifically, the lateral movement of the external structure can push the main extrusion plate 29, causing it to move laterally within the glycerin main storage chamber 23 and extrude glycerin, thereby generating damping.

[0051] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides the following technical solution:

[0052] The first transmission rod 13 has a receiving groove 14 inside, and a transmission tooth groove 15 is provided at the lower end of the receiving groove 14. The transmission tooth groove 15 is welded and fixed to the receiving groove 14. A transmission gear 16 is provided at the upper end of the transmission tooth groove 15 outside, and the outside of the transmission gear 16 is meshed with the outside of the transmission tooth groove 15.

[0053] Specifically, the damping can be detected by the lateral movement of the first transmission rod 13 in conjunction with the meshing connection between the auxiliary extrusion plate 26 and the transmission tooth groove 15.

[0054] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides the following technical solution:

[0055] A rotation detection module 17 is provided at the front end of the transmission gear 16. The rotation detection module 17 is responsible for uploading the detected rotation frequency of the transmission gear 16 to the rotation recording module 30, data processing module 31, data storage module 32 and data extraction module 33 inside the rotation detection module 17.

[0056] The rotation recording module 30 is used to record the rotation direction, rotation frequency and rotation time of the transmission gear 16;

[0057] The data processing module 31 is used to process and calculate the data recorded by the rotation recording module 30, and to calculate and know the swaying frequency and swaying force of the building exterior.

[0058] Data storage module 32 is used to store the data recorded and calculated by data processing module 31 and rotation recording module 30;

[0059] The data extraction module 33 is used by maintenance personnel to extract vibration reduction data for the required time period from the data processing module 31.

[0060] The data processing module 31 calculates the swaying frequency and swaying force of the building exterior, including the following steps:

[0061] Step 1: Based on the rotation direction, rotation frequency, and rotation time of the transmission gear 16, determine the sway acceleration of the building exterior and construct the sway response equation of the building exterior:

[0062] M*v+C*v+K*v=-M*Z;

[0063] Where M represents the mass diagonal matrix at different damping locations on the exterior of the building. m xy C represents the damped mass at coordinates (x, y); C represents the damping matrix. c xy This represents the damping coefficient at coordinates (x, y); K represents the external stiffness matrix of the building. k xy Z represents the building stiffness at the building's external location with damping at coordinates (x, y); Z represents the building sway matrix. h xy This represents the sway coordinates of the damper at its external position (x, y) on the building.

[0064] Step 2: Determine the building's sway frequency based on the building's sway response coefficient.

[0065]

[0066] Wherein, ε(h) xy ) represents the coordinate function of the building's swaying; ω represents the swaying frequency of the building;

[0067] Step 3: Determine the swaying force of the building based on the building sway response coefficient.

[0068]

[0069] Where F represents the building's sway intensity; This represents the sway coordinate value of the i-th damper at the position (x, y); m i Let represent the mass of the i-th damper.

[0070] Specifically, in the process of calculating the building sway frequency and sway force, this invention is mainly based on the installation position of the damper and the mass of the damper at different positions. In this process, the transmission gear in the new type of damper plays a calculation and measurement function. First, under the action of neutral force, the rotation speed of the gear determines the sway acceleration of the building detected by the new type of damper. Because the new damper is calculated for the building, it cannot be just a single damper. Therefore, this invention uses a focusing matrix method for calculation. In the focusing matrix, the mass of the new damper is different at different coordinates. The damping coefficient of the new damper, the stiffness of the building, and the external acceleration of the building are calculated using the mass coefficient to construct the building's sway response equation. This is because the intensity of the sway is only highly related to these three parameters. Based on the detected sway response parameters, this invention introduces models for calculating the building's sway frequency and sway intensity, respectively. In the sway frequency calculation model, the derivative introduced in this invention determines the sway frequency, which is the ratio of the sway parameters within one cycle, by using the ratio of the building's sway coordinate function under the action of gravity g to the total sway response coefficient. The sway force is calculated by calculating the ratio of the building's sway response coefficient to the number of dampers under different new types of dampers' mass coefficients, thereby calculating the building's sway intensity. The sway intensity is then used to determine the building's sway force. There are corresponding sway conversion tables for both sway intensity and sway frequency. The sway conversion tables determine the sway force and sway frequency under different sway intensities. Through the above method, the sway force and frequency can be determined more accurately.

[0071] Specifically, the rotation recording module 30, data processing module 31, data storage module 32, and data extraction module 33 detect and process the data, and record the processed data to facilitate subsequent inspection by maintenance personnel.

[0072] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides the following technical solution:

[0073] The upper end of the rotation detection module 17 is provided with a data display module 18. One end of the data display module 18 is provided with a fixing block 19. A second transmission rod 20 is provided on one side of the fixing block 19. The two sides of the second transmission rod 20 are welded and fixed to the auxiliary damping medium storage frame 21 and the fixing block 19, respectively.

[0074] Specifically, the data display module 18 displays the data from the rotation recording module 30, data processing module 31, data storage module 32, and data extraction module 33, facilitating maintenance by maintenance personnel.

[0075] For further details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment provides the following technical solution:

[0076] A connecting strip 3 is provided on the other side of the first damper bearing end 1 and the second damper bearing end 2. A protective frame 4 is provided on the outside of one of the connecting strips 3. An air flow cavity 8 is provided inside the protective frame 4. An exhaust fan blade 22 is provided on one side inside the air flow cavity 8, and one end of the exhaust fan blade 22 is sealed to one side inside the air flow cavity 8.

[0077] Specifically, by drawing in external air through the exhaust fan blades 22, the external air can enter the airflow cavity 8 inside the protective frame 4, and the airflow cavity 8 can dissipate heat from the damper.

[0078] For further details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment provides the following technical solution:

[0079] The front end of the outer protective frame 4 is provided with a wrapping piece 6. Both sides of the upper end of the wrapping piece 6 are provided with rotating connecting shafts 5, and one side of the rotating connecting shaft 5 is rotatably connected to one side of the upper end of the wrapping piece 6. The front end of the wrapping piece 6 is provided with a pull handle 7, and the pull handle 7 is welded and fixed to the front end of the wrapping piece 6. One side of the outer side of the wrapping piece 6 is connected to one side of the inner side of the protective frame 4 with a slot.

[0080] Specifically, the orientation of the wrapping piece 6 can be adjusted and the air flow cavity 8 can be exposed by rotating it outside the rotating connecting shaft 5. The exposed air flow cavity 8 can directly display the damper and the data display module 18, which is convenient for maintenance personnel.

[0081] Working principle: When using a damper, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5To improve the damping capacity of the device during actual use and to increase the instantaneous damping that the damper can withstand, external force is transmitted to the main extrusion plate 29 via the transmission roller 11. The lateral movement of the main extrusion plate 29 can push the glycerin inside the main damping medium storage frame 10. Some of the glycerin can pass through the main extrusion plate 29 during the extrusion process, while the other part of the glycerin enters the secondary damping medium storage frame 21 through the buffer through hole 28. The first secondary glycerin storage cavity 24 and the second secondary glycerin storage cavity 25 entering the secondary damping medium storage frame 21 can respectively push the secondary extrusion plate 26 to move laterally. The instantaneous impact force generated by multiple auxiliary positions allows the damping effect to be recorded during the use of the damper. While the force is transmitted through the lateral movement of the transmission roller 11, the lateral movement of the transmission roller 11 can drive the first transmission rod 13 to move laterally. The lateral movement of the first transmission rod 13 can drive the transmission gear through the transmission tooth groove 15 inside the receiving groove 14. The rotation of transmission gear 16 is detected and recorded by the rotation recording module 30 inside the rotation detection module 17. The recorded data is then processed by the data processing module 31 to calculate the damper's buffering capacity. Subsequently, the data storage module 32 stores the detected and calculated data, and the data extraction module 33 stores the corresponding data and displays it on the data display module 18. In order to improve the damper's self-reset capability, when the damper stops damping, the active reset springs 27 at both ends of the secondary extrusion plate 26 rebound and actively push the secondary extrusion plate 26 to move to the middle inside the secondary damping medium storage frame 21. During the lateral movement of the secondary extrusion plate 26, it will squeeze the glycerin and make it flow back into the glycerin main storage chamber 23. The glycerin main storage chamber 23 will then push the main extrusion plate 29 to the middle inside the main damping medium storage frame 10 and reset it.
