Description

Technical Field

[0001] The present invention relates to a viscous damper, in particular to a viscous damper with an early warning function which is applied in the field of general building construction. Background Art

[0002] Traditional building structures are earthquake-resistant by enhancing the seismic performance of the structure itself to resist natural disasters such as earthquakes, wind, snow, and tsunamis. Due to the uncertainty of the intensity and characteristics of natural disasters, the structures designed by traditional earthquake-resistant methods do not have the ability to self-regulate, so when an earthquake occurs, it often causes significant economic losses and casualties. The development and application of viscous energy-dissipating dampers is equivalent to installing "airbags" on buildings or bridges. When an earthquake occurs, the damper absorbs and consumes the impact energy of the earthquake on the building structure to the maximum extent, greatly alleviating the impact and damage caused by the earthquake to the building structure. However, traditional viscous dampers have no early warning function, and there are still major safety hazards when an earthquake occurs.

[0003] In order to solve the problem of no earthquake warning function, a certain viscous damper on the market adopts a whistle structure design and has a certain market share.

[0004] The specification of Chinese invention patent application CN119288102A discloses a new type of viscous damper with early warning function, including a first connecting component, a piston component, an early warning device and a second connecting component, wherein the piston component includes a first piston rod, a second piston rod, a seal, silicone oil, a piston and an oil cylinder, wherein the first piston rod is fixedly connected to the first connecting component, and seals for sealing the first piston rod, the second piston rod and the silicone oil are fixed at both ends of the oil cylinder, and two groups of the seals are respectively slidably connected to the first piston rod and the second piston rod, and a piston is matched in the inner wall gap of the oil cylinder; the early warning component includes a permanent magnet, an RGB three-color lamp, a copper wire and a rear connecting pipe, and the other end of the first piston rod is wound with a copper wire, and the copper wire is electrically connected to the RGB three-color lamp. A second connecting component is provided, which can change the installation angle and position, and realize installation more conveniently, and can convert vibration energy into electric current, and use the RGB three-color lamp for alarm prompt.

[0005] Although the above technology solves the problem that the viscous damper cannot generate earthquake warning while buffering the earthquake when an earthquake occurs, the actual condition of the viscous damper itself is unclear after the earthquake. This requires a lot of manpower and material resources to repair it, which not only increases the difficulty of maintaining the viscous damper and increases its application cost, but also brings certain risks due to the low maintenance efficiency. When an earthquake occurs again within a short time interval, it is difficult to effectively ensure the safety of buildings and residents. Therefore, enhancing the early warning function of the viscous damper on its own status has become one of the important issues that need to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0038] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0039] The first implementation method:

[0040] Figure 1 - Fig.12 A viscous damper with an early warning function is shown, comprising a building wall 1 and a damper maintenance platform. A plurality of mounting grooves 11 are provided on the building wall 1. Wall supports 3 are fixedly installed on the upper and lower inner walls of the mounting grooves 11. A damper body 2 is hinged between the two wall supports 3. A monitoring sheath 4 is provided at the outer end of the damper body 2.

[0041] The damper body 2 includes a cylinder body 21, a piston cylinder 23 is slidably arranged in the cylinder body 21, and the left end of the piston cylinder 23 extends to the outside of the cylinder body 21, a piston 22 is fixedly connected to the piston cylinder 23 and is in sealing and sliding cooperation with the inner wall of the cylinder body 21, and the left end of the piston cylinder 23 and the right end of the cylinder body 21 are both fixedly connected with a hinge block 24 that cooperates with the wall support 3;

[0042] A pair of linkage reaction components 5 are embedded at both ends of the cylinder body 21, and the two linkage reaction components 5 on the same side are respectively distributed on the left and right sides of the piston 22, and a plurality of frequency contact blocks 6 matching the linkage reaction components 5 are fixedly connected to the inner wall of the monitoring sheath 4;

[0043] The damper maintenance platform is equipped with a linkage warning system, which includes a linkage warning processing unit. The input end of the linkage warning processing unit is connected to the damping anti-seismic parameter input unit, the application life parameter unit, the damping state linkage unit and the vibration frequency sensing unit. The output end of the linkage warning processing unit is connected to the epicenter warning unit, the post-earthquake warning unit and the anti-seismic data output unit.

[0044] The input ends of the damping anti-seismic parameter input unit and the application life parameter unit are both connected to the data port signal set on the damper maintenance platform, the input end of the damping state linkage unit is connected to the linkage reaction component 5 signal, the input end of the vibration frequency sensing unit is connected to the frequency contact block 6 signal, the output end of the epicenter warning unit is connected to the alarm signal set at the right end of the cylinder body 21, and the output ends of the post-earthquake warning unit and the anti-seismic data output unit are both connected to the data port signal set on the damper maintenance platform. Through the cooperation of the linkage reaction component 5, the frequency contact block 6 and the linkage warning system, the real-time status of the damper body 2 can be effectively collected. On the one hand, it can generate earthquake warning in time during the anti-seismic action of the damper body 2, effectively remind residents to take safe response actions, and effectively improve the safety of the damper body 2 during its application; on the other hand, it can display the status of the damper body 2 after the damper body 2 has completed its anti-seismic action, and promptly issue early warning prompts for abnormal damper bodies 2, effectively reducing the difficulty of maintaining the damper body 2 after the earthquake, reducing the labor intensity of maintenance personnel, promoting the timeliness and effectiveness of replacement and maintenance of the damper body 2, effectively ensuring the safety of buildings and residents, and thereby effectively promoting the application and development of the damper body 2.

[0045] Figure 3 - Fig.12 It is shown that sealing blocks are embedded at the left end of the cylinder body 21 and the right side of the inner wall of the cylinder body 21, the piston cylinder 23 and the sealing block are in sealed sliding cooperation, the inside of the cylinder body 21 is filled with hydraulic oil 26 between the piston 22 and the sealing block on the left side, and the inside of the cylinder body 21 is filled with damping medium 25 between the piston 22 and the sealing block on the right side. The damping medium 25 and the hydraulic oil 26 can effectively buffer the vibration, effectively enhance the earthquake resistance of the building, and improve the safety of the building.

[0046] Figure 1 and Fig.10 - Fig.12It is shown that the hinge block 24 on the left is hingedly matched with the wall support 3 on the upper side, and the hinge block 24 on the right is hingedly matched with the wall support 3 on the lower side. The wall support 3 is hinged with the cylinder body 21 and the piston cylinder 23 through the hinge block 24, so that when an earthquake occurs, the vibration can be effectively transmitted. The sliding of the piston cylinder 23 and the piston 22 in the cylinder body 21, as well as the buffering effect of the hydraulic oil 26 and the damping medium 25, achieve an anti-seismic effect, and effectively improve the safety of the building.

[0047] Figure 3 - Fig. 9 The linkage reaction assembly 5 is shown to include a sealing plug shell 51 that is sealed and embedded in the cylinder body 21, and an early warning slider 52 is provided in the sealing plug shell 51 for sealing and sliding. The end of the early warning slider 52 close to the piston cylinder 23 is fixedly connected to a linkage push rod 53, and the end of the linkage push rod 53 close to the piston cylinder 23 extends into the cylinder body 21 and is slidably matched with the cylinder body 21. The end of the early warning slider 52 away from the piston cylinder 23 is fixedly connected to a reaction feeler rod 54, and the reaction feeler rod 54 extends to the outside of the sealing plug shell 51 away from the piston cylinder 23 and cooperates with the frequency contact block 6. The early warning slider 52, the linkage push rod 53 ... The cooperation between the moving push rod 53 and the reaction contact rod 54 can effectively realize the visualization of the changes in the pressure of the hydraulic oil 26 and the damping medium 25. Through the up and down sliding action of the moving push rod 53 in the sealing plug shell 51 and the triggering feedback of the frequency contact block 6, the real-time data collection of the state of the cylinder body 21 during the earthquake resistance process can be effectively realized. On the one hand, it can promote the effective collection and response of the real earthquake data. On the other hand, it can also judge the state of the damper body 2 according to the data after the earthquake, and can carry out timely and effective maintenance on it to ensure its subsequent safety.

[0048] Figure 3 - Fig. 9 It is shown that an elastic fuse strip 531 is fixedly connected between the end of the early warning slider 52 close to the piston cylinder 23 and the inner wall of the sealing plug shell 51 close to the piston cylinder 23, and the elastic sleeve 541 is fixedly connected between the end of the early warning slider 52 away from the piston cylinder 23 and the inner wall of the sealing plug shell 51 away from the piston cylinder 23, and the elastic sleeve 541 is fixedly connected between the end of the early warning slider 52 away from the piston cylinder 23 and the inner wall of the sealing plug shell 51 away from the piston cylinder 23.

[0049] The stiffness coefficient of the elastic fuse strip 531 is smaller than that of the elastic sleeve 541. When the piston 22 and the piston cylinder 23 are in a stationary state, the elastic fuse strip 531 and the elastic sleeve 541 are both in a contracted state.

[0050] Elastic trigger protrusions 55 are fixedly connected to the left and right inner walls of the sealing plug shell 51, and when the piston 22 and the piston cylinder 23 are in a stationary state, the elastic trigger protrusion 55 is located on the side of the early warning slider 52 away from the piston cylinder 23, and is in abutment with the early warning slider 52. The input end of the damping state linkage unit is connected to the elastic trigger protrusion 55 signal. The semi-compression effect of the elastic sleeve 541 and the elastic fuse strip 531 can effectively ensure the balance between the early warning slider 52, the linkage push rod 53 and the reaction touch rod 54 and the pressure of the damping medium 25 or the hydraulic oil 26, thereby effectively realizing the real-time display of the pressure changes in the damping medium 25 or the hydraulic oil 26, and can also be used after the earthquake. Whether leakage abnormality occurs is determined based on the data of whether the elastic trigger protrusion 55 is continuously triggered by the early warning slider 52, thereby further promoting the maintenance of the damper body 2 and playing an effective early warning role in the future. In addition, with the cooperation of the elastic trigger protrusion 55 and the damping state linkage unit, effective data collection of the position of the early warning slider 52 is achieved, and the pressure change data of the damping medium 25 and the hydraulic oil 26 are further displayed, thereby improving the accuracy of the state monitoring of the damper body 2 and the reliability of the data, effectively reducing the difficulty of maintenance, and providing effective data support for the subsequent research and development and manufacturing of the damper body 2, thereby promoting the development and improvement of the damper body 2.

[0051] Figure 3 - Fig.12 It is shown that the monitoring sheath 4, the sealing plug shell 51, the early warning slider 52, the linkage top rod 53, the reaction touch rod 54 and the frequency touch block 6 are all made of heat-conducting materials, and the elastic fuse strip 531 is made of an elastic fuse material. The elastic fuse strip 531 can be made of low-melting-point metals and their alloys or organic polymer materials, for example, lead-zinc alloy, bismuth-indium alloy, polycaprolactone, and low-melting-point agarose. It can maintain its elastic effect when it is lower than 50°C to 60°C, and produce a fusing effect when the temperature approaches or reaches 50°C to 60°C, thereby effectively producing a high-temperature early warning effect. The elastic fuse strip 531 can be made into a spiral In the application process, the linkage push rod 53 can conduct the temperature in the cylinder body 21, and conduct the heat to the elastic fuse strip 531 through the thermal conductivity of the early warning slider 52 and the sealing plug shell 51. The fusing characteristics of the elastic fuse strip 531 can effectively display whether the damping medium 25 and the hydraulic oil 26 have temperature abnormalities during the earthquake resistance process, and produce an early warning prompt after the earthquake, so as to focus on the maintenance of the damper body 2 with temperature abnormalities after the earthquake, thereby improving the timeliness and effectiveness of maintenance, effectively avoiding the risks caused by low maintenance efficiency, and further promoting the safety protection function of the damper body 2.

[0052] It should be noted that, in the process of the damper body 2 resisting earthquakes, its internal temperature data can be analyzed and judged according to its anti-seismic effect. When the reference environment is about 20°C, if the earthquake intensity is small, the deformation and movement amplitude of the viscous damper are relatively small, the friction and shearing effect between molecules are weak, and the heat generated is small. At this time, its internal temperature may be only a few degrees higher than the ambient temperature. The temperature inside the damper body 2 is generally between 20°C and 25°C. If the earthquake intensity is moderate, the movement speed and deformation degree of the viscous damper will increase. , the friction and internal friction between molecules increase, so that the internal temperature has a significant increase. In this case, the internal temperature may be about 10℃~30℃ higher than the ambient temperature, and the internal temperature of the damper body 2 may be between 30℃~50℃; if under the action of a strong earthquake, the viscous damper needs to withstand large deformation and high-speed movement, and the violent friction and collision between molecules will generate a lot of heat, causing the internal temperature to rise sharply. At this time, the internal temperature of the damper body 2 may be 30℃-50℃ higher than the ambient temperature or even higher, and may reach 60℃~80℃ or higher. However, when the internal temperature of the damper body 2 is too high, its material properties, internal structure and performance parameters will be damaged, so it needs to be replaced or maintained. In this embodiment, 50℃~60℃ is selected as the safety fuse temperature, which can directly and effectively send an early warning reminder to the maintenance personnel after the earthquake, so that they can replace or maintain the damper body 2 in a timely and effective manner, ensure the safety of the damper body 2 during application, and promote the timeliness of the maintenance personnel's safety maintenance of the damper body 2.

[0053] Figure 1 - Fig.12It is shown that the damper maintenance platform can be installed separately on a single-building location composed of a building wall 1, or it can be installed in the overall park. According to needs, the status of the damper body 2 on the independent building or the status of the damper body 2 on each building in the entire park can be monitored, so it can be effectively applied to applications with different needs and effectively promote the application and development of the damper body 2. During the application of the damper maintenance platform and the damper body 2, relevant technical personnel can input seismic parameters about the damper body 2 to the damping seismic parameter input unit through the data port of the damper maintenance platform. These parameters include but are not limited to seismic temperature data, vibration pressure change data, vibration frequency data, earthquake level data, building height data, and data and position of the damper body 2 in the building and other related data. The damping seismic parameter input unit transmits these seismic data to the linkage early warning processing unit, and the linkage early warning processing unit can process and apply these seismic parameters. Relevant technical personnel transmit relevant parameter data about the application life of the damper body 2 to the application life parameter unit through the data port of the damper maintenance platform. These data include but are not limited to the size, stroke, pressure, age, vibration effectiveness range and various intensities of the damper body 2 and other related data. The application life parameter unit transmits the life parameters of the damper body 2 to the linkage early warning processing unit, and the linkage early warning processing unit processes and applies these data.

[0054] During the anti-vibration operation of the damper body 2, the vibration will occur until the piston cylinder 23 drives the piston 22 to move left and right in the cylinder body 21. When the piston cylinder 23 drives the piston 22 to move left, the space of the hydraulic oil 26 is compressed, causing the pressure in the hydraulic oil 26 to increase, and the space of the damping medium 25 is released, causing the pressure in the damping medium 25 to decrease.

[0055] Therefore, the linkage push rod 53 located at the hydraulic oil 26 moves toward the side away from the piston cylinder 23 when the hydraulic oil 26 is pressurized, driving the early warning slider 52 to move toward the side away from the piston cylinder 23 in the sealing plug shell 51, and then the reaction touch rod 54 moves toward the side away from the piston cylinder 23 under the linkage of the early warning slider 52. At this time, the elastic fuse strip 531 is elongated and deformed, and the elastic sleeve 541 is compressed. When the early warning slider 52 continues to move toward the side away from the piston cylinder 23, it gradually moves away from the elastic trigger protrusion 55 and is in contact with the elastic trigger After the protrusion 55 is out of contact, the damping state linkage unit can obtain the signal that the elastic triggering protrusion 55 is not triggered by the warning slider 52 at this time, and obtain the data of the left disconnection; and when the vibration amplitude is large, causing the pressure in the hydraulic oil 26 to increase to a larger range, the linkage push rod 53 will drive the reaction contact rod 54 to continuously move toward the side away from the piston cylinder 23 through the warning slider 52, until the upper end of the reaction contact rod 54 contacts the frequency contact block 6, and the vibration frequency sensing unit receives the contact signal transmitted by the frequency contact block 6, and obtains the data of the left contact;

[0056] Therefore, when the damping medium 25 is decompressed, the linkage push rod 53 located at the damping medium 25 reduces the contraction pressure of the elastic sleeve 541, and the elastic sleeve 541 is elongated and deformed. Therefore, the elastic sleeve 541 can squeeze and push the early warning slider 52, and the elastic sleeve 541 drives the early warning slider 52 and the reaction contact rod 54 to move toward the side close to the piston cylinder 23, thereby driving the linkage push rod 53 to move toward the side close to the piston cylinder 23, and compressing the elastic fuse bar 531, and the elastic fuse bar 531 is contracted and deformed. At the same time, in the process of the early warning slider 52 moving toward the side close to the piston cylinder 23, it gradually moves away from the elastic trigger protrusion 55 and does not contact the elastic trigger protrusion 55. The damping state linkage unit can obtain the disconnection signal transmitted by the elastic trigger protrusion and the disconnection data on the right side. Moreover, because the reaction contact rod 54 moves toward the side close to the piston cylinder 23 under the linkage of the early warning slider 52, the vibration frequency sensing unit receives the signal that the frequency contact block 6 is not triggered at this time, and obtains the data that the right side is not triggered.

[0057] When the piston cylinder 23 drives the piston 22 to move rightward, the space of the hydraulic oil 26 is released, causing the pressure in the hydraulic oil 26 to decrease, and the space of the damping medium 25 is compressed, causing the pressure in the damping medium 25 to increase;

[0058] Therefore, when the hydraulic oil 26 of the piston cylinder 23 is depressurized, the pressure of the elastic sleeve 541 to contract is reduced, and the elastic sleeve 541 is elongated and deformed. Therefore, the elastic sleeve 541 can push the early warning slider 52, and the elastic sleeve 541 drives the early warning slider 52 and the reaction contact rod 54 to move toward the side close to the piston cylinder 23, thereby driving the linkage push rod 53 to move toward the side close to the piston cylinder 23, and compressing the elastic fuse bar 531, and the elastic fuse bar 531 is contracted and deformed. At the same time, in the process of the early warning slider 52 moving toward the side close to the piston cylinder 23, it gradually moves away from the elastic trigger protrusion 55 and does not contact the elastic trigger protrusion 55. The damping state linkage unit can obtain the disconnection signal transmitted by the elastic trigger protrusion and the disconnection data on the right side. Moreover, because the reaction contact rod 54 moves toward the side close to the piston cylinder 23 under the linkage of the early warning slider 52, the vibration frequency sensing unit receives the signal that the frequency contact block 6 is not triggered at this time, and obtains the data that the right side is not triggered.

[0059] Therefore, when the damping medium 25 is pressurized, the linkage push rod 53 at the damping medium 25 moves toward the side away from the piston cylinder 23, driving the early warning slider 52 to move toward the side away from the piston cylinder 23 in the sealing plug shell 51, and then the reaction touch rod 54 moves toward the side away from the piston cylinder 23 under the linkage of the early warning slider 52. At this time, the elastic fuse strip 531 is elongated and deformed, and the elastic sleeve 541 is compressed. When the early warning slider 52 continues to move toward the side away from the piston cylinder 23, it gradually moves away from the elastic trigger protrusion 55 and is in contact with the elastic trigger After the protrusion 55 is out of contact, the damping state linkage unit can obtain the signal that the elastic trigger protrusion 55 is not triggered by the early warning slider 52 at this time, and obtain the data of the left disconnection; and when the vibration amplitude is large, causing the pressure in the hydraulic oil 26 to increase to a larger range, the linkage push rod 53 will drive the reaction touch rod 54 through the early warning slider 52 to produce a continuous movement toward the side away from the piston cylinder 23 until the upper end of the reaction touch rod 54 and the frequency contact block 6 produce a contact effect, and the vibration frequency sensing unit receives the contact signal transmitted by the frequency contact block 6 to obtain the data of the left side contact.

[0060] During the anti-seismic process of the damper body 2, as the piston cylinder 23 drives the piston 22 to move left and right in the cylinder body 21, the changes and triggering states of the linkage reaction component 5 are continuously cycled as described above, so that the damping state linkage unit and the vibration frequency sensing unit can effectively obtain relevant data.

[0061] Since when the damper body 2 is in a stationary state, the elastic trigger protrusion 55 is located on the side of the warning slider 52 away from the piston cylinder 23, and is in abutment with the warning slider 52, and the elastic trigger protrusion 55 is in a connected state, so when the warning slider 52 moves toward and away from the piston cylinder 23, the warning slider 52 can exert a deformation and squeezing effect on the elastic trigger protrusion 55 during the movement, so that the elastic trigger protrusion 55 can maintain the connected effect for a period of time, and when the warning slider 52 moves toward and close to the piston cylinder 23, it will directly cause the non-contact disconnection between the elastic trigger protrusion 55 and the warning slider 52, and then the left disconnection signal received by the damping state linkage unit will be later than the right disconnection signal. The damping state linkage unit can judge the movement state of the piston cylinder 23 in the cylinder body 21 at this time according to the acquired data gap, and then analyze and process the movement state data. The linkage warning processing unit transmits the state data of the pressure change of the damping medium 25 and the hydraulic oil 26 in the cylinder 21 to the linkage warning processing unit. The linkage warning processing unit determines whether it is in an earthquake state at this time and the size and frequency data of the earthquake fluctuations according to the state data. After the linkage warning processing unit determines that an earthquake has occurred, it sends an epicenter warning control to the epicenter warning unit, so that the epicenter warning unit starts the alarm located at the right end of the cylinder 21, directly warning the residents in the building, reminding the residents to avoid danger in time and ensure their safety. The linkage warning processing unit will also transmit the state data of the damper body 2 during earthquake resistance to the damper maintenance platform through the earthquake resistance data output unit and the data port. On the one hand, it can remind the maintenance personnel of the earthquake situation, and on the other hand, it can also provide real-time data feedback to assist the maintenance personnel in obtaining the safety status of the building at this time, effectively playing a timely and effective emergency response;

[0062] The vibration frequency sensing unit receives data on whether the left and right side contacts are triggered or not, and obtains the frequency at which the frequency contact block 6 is triggered. According to the frequency at which the frequency contact block 6 is triggered, the stroke data of the offset movement of the piston cylinder 23 is effectively obtained at this time, and then the vibration amplitude data can be judged. The data is then transmitted to the linkage early warning processing unit. The linkage early warning processing unit can judge the level of the earthquake at this time based on the vibration amplitude data, and then transmit real and effective earthquake data to the seismic data output unit to assist in subsequent emergency repairs and rescue operations.

[0063] When the earthquake intensity is large, causing the piston cylinder 23 to move frequently and with a large stroke, as the piston cylinder 23 and the piston 22 move, the buffering and pressure changes of the damping medium 25 and the hydraulic oil 26 will cause the temperature in the damping medium 25 and the hydraulic oil 26 to continue to rise. The rising temperature will be transmitted to the sealing plug shell 51 through the linkage push rod 53, the sealing plug shell 51 and the early warning slider 52, and will act on the elastic fuse strip 531. Therefore, after the elastic fuse strip 531 absorbs heat, when the temperature on it reaches the melting temperature of the elastic fuse strip 531, the elastic fuse strip 531 will produce a melting effect, and then directly disconnect, and the contact with the The elastic resistance of the elastic sleeve 541 causes the elastic sleeve 541 to produce a fully extended deformation, which in turn causes a sudden decrease in the connection frequency of the elastic trigger protrusion 55 and the triggering frequency of the frequency contact block 6 in the subsequent pressure change process of the damping medium 25 and the hydraulic oil 26. Therefore, at the epicenter, the linkage warning processing unit can judge that the cylinder body 21 is in an abnormally high temperature state at this time through the sudden change data transmitted by the damping state linkage unit and the vibration frequency sensing unit. On the one hand, a high-frequency alarm effect is generated through the epicenter warning unit, and on the other hand, the state data of the damper body 2 in the building is transmitted to the outside world through the earthquake resistance data output unit;

[0064] Then, after the earthquake, due to the disconnection of the elastic fuse strip 531, the early warning slider 52 cannot produce an effective reset effect. The early warning slider 52 does not contact the elastic trigger protrusion 55 under the elongation of the elastic sleeve 541, so that the damping state linkage unit obtains the non-contact data of the elastic trigger protrusion 55, and then transmits it to the linkage early warning processing unit. The linkage early warning processing unit determines that the damper body 2 has an abnormal temperature at the epicenter based on the data that the elastic trigger protrusion 55 does not contact at this time, and then transmits the post-earthquake early warning data to the post-earthquake early warning unit, so that the post-earthquake early warning unit sends an early warning signal to the damper maintenance platform through the data port, so that the maintenance personnel can give priority to the maintenance and replacement of the abnormal damper body 2, and then the maintenance personnel perform maintenance and maintenance on the damper body 2 in turn according to the epicenter data of other damper bodies 2 transmitted by the earthquake-resistant data output unit, thereby effectively reducing the maintenance difficulty and maintenance work intensity, improving the timeliness and effectiveness of the maintenance work, and effectively ensuring the safety of the damper body 2.

[0065] When the damping medium 25 and the hydraulic oil 26 in the cylinder body 21 leak abnormally after the shock, the pressure of the damping medium 25 and the hydraulic oil 26 will decrease, and then the elastic force of the elastic sleeve 541 will be released, resulting in elongation deformation, and then driving the warning slider 52 to move toward the side close to the piston cylinder 23, so that the warning slider 52 is away from the elastic trigger protrusion 55, and the elastic trigger protrusion 55 is no longer triggered. The damping state linkage unit obtains the non-contact data of the elastic trigger protrusion 55, and then transmits it to the linkage warning processing unit. The linkage warning processing unit receives the non-contact data of the elastic trigger protrusion 55 at this time. The data touched by the earthquake can be used to determine whether the damper body 2 may have abnormal leakage after the earthquake, and then the post-earthquake warning data can be transmitted to the post-earthquake warning unit, so that the post-earthquake warning unit can send a warning signal to the damper maintenance platform through the data port, so that the maintenance personnel can give priority to the maintenance and replacement of the abnormal damper body 2, and then the maintenance personnel will maintain and service the damper body 2 in turn according to the epicenter data of other damper bodies 2 transmitted by the earthquake-resistant data output unit, thereby effectively reducing the difficulty and intensity of maintenance work, improving the timeliness and effectiveness of maintenance work, and effectively ensuring the safety of the damper body 2.

[0066] Second implementation method:

[0067] Figure 1 - Fig.12 A viscous damper with an early warning function is shown, in which a monitoring sleeve 4 is fixedly provided on the outer end of the cylinder body 21, and a support bar fixedly connected to the cylinder body 21 is fixedly connected inside the monitoring sleeve 4. The monitoring sleeve 4 can not only protect the cylinder body 21 to avoid damage during installation and maintenance, but also effectively promote heat dissipation during the anti-vibration process of the damper body 2, thereby ensuring the continuous effectiveness of the anti-vibration action of the damper body 2.

[0068] Figure 1 - Fig.12 It is shown that the monitoring sheath 4 is made of a transparent material, and the inner wall of the monitoring sheath 4 is coated with an electrochromic coating, and the electrochromic coating is made of an irreversible color-changing material with a one-way color change. The irreversible color-changing material with a one-way color change can be a polyaniline coating, an organic-inorganic composite coating containing transition metal ions, and some special organic dye polymer coatings, etc. Those skilled in the art can select them according to actual needs;

[0069] An elastic trigger switch is embedded in the frequency contact block 6. The elastic trigger switch extends to the outside of the frequency contact block 6 away from one end of the cylinder body 21, and is fixedly connected to a conductive contact piece that abuts the electrochromic coating. When the frequency contact block 6 is abutted and triggered by the reaction contact rod 54 to produce squeezing, the elastic trigger switch will conduct current on the conductive contact piece, so that the current can be transmitted to the electrochromic coating through the conductive contact piece, causing it to produce an irreversible color change effect. In the subsequent maintenance personnel, according to the color change of the monitoring sheath 4, they can intuitively and effectively judge the seismic state of the damper body 2, and focus on the maintenance of the color-calibrated damper body 2 to ensure its application safety in the subsequent seismic process.

[0070] Figure 1 - Fig.12 It is shown that during the earthquake resistance of the damper body 2, as the reaction contact rod 54 moves toward the side away from the piston cylinder 23 and contacts the frequency contact block 6, the elastic trigger switch in the frequency contact block 6 is closed, and current is passed into the electrochromic coating, so that the electrochromic coating produces a color change reaction and an irreversible color change phenomenon, that is, when the frequency contact block 6 is not contacted and the elastic trigger switch in it is disconnected, the electrochromic coating still maintains the color change phenomenon. In the process of the frequency contact block 6 being continuously contacted, current is passed into the electrochromic coating, and the color of its color change image will gradually deepen. Then, during the maintenance of the damper body 2 by the maintenance personnel, the linkage warning processing unit does not transmit the warning data about the damper body 2 to the post-earthquake warning unit in time. The maintenance personnel replace and repair the damper body 2 with a darker color according to the color display of the monitoring sheath 4, so as to avoid the occurrence of unnoticed damage and deformation of the damper body 2 and further improve the safety protection function of the damper body 2.

[0071] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
