DETAILED DESCRIPTION

[0025] The intelligent assembled hybrid multi-energy dissipation active vibration control support device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] See also Figure 1 The present invention discloses an intelligent assembled hybrid multi-energy dissipation active vibration control support device, comprising a steel frame 1, an electrorheological damping anti-buckling support 2, a data acquisition unit, a control unit 3 and a photovoltaic curtain wall 4. The steel frame 1 comprises a support plate 11 and a support column 12, and the support plate 11 and the support column 12 are assembled in a modular manner to form a main structure of the building. The electrorheological damping anti-buckling support 2 is installed on the steel frame 1, the data acquisition unit is arranged at a key position node of the building, and the photovoltaic curtain wall 4 is surrounded by the outside of the steel frame 1, and the electrorheological damping anti-buckling support 2, the data acquisition unit and the photovoltaic curtain wall 4 are respectively connected to the control unit 3.

[0027] See also Figure 2 Four electrorheological damping anti-buckling supports 2 connected in an "X" shape are installed between two support columns 12 and a support plate 11 in a steel frame 1. The electrorheological damping anti-buckling support 2 includes an electrorheological damper structure and an anti-buckling support structure. The electrorheological damper structure absorbs low-frequency and medium-frequency vibration energy through viscoelastic adjustment, and the anti-buckling support structure dissipates high-intensity vibration energy through plastic deformation, thereby achieving multiple energy dissipation effects.

[0028] See also Figure 3 and Figure 4 The electrorheological damper structure includes a sleeve 211, a first piston 212, a second piston 213 and a piston rod 214, and the sleeve 211 is filled with an electrorheological fluid 215. The first piston 212 and the second piston 213 are slidably installed in the sleeve 211, and a throttle hole 216 is provided on the first piston 212 and the second piston 213, and the flow path of the electrorheological fluid 215 is regulated by the throttle hole 216 provided on the piston. The number and size of the throttle holes 216 can be designed according to the actual building vibration characteristics to optimize the flow path and damping performance of the electrorheological fluid 215, so as to adapt to the external force of various earthquake intensities and frequencies.

[0029] See also Figure 4 and Figure 5The electrorheological damper structure also includes an end plate 217, a connecting plug 218 and a current wire 219. The piston rod 214 sequentially connects the first piston 212, the second piston 213 and the end plate 217. The end plate 217 is clamped on the first port of the sleeve 211. The connecting plug 218 is arranged on the end plate 217 and exposed outside the sleeve 211. The current wire 219 is arranged in the sleeve 211. The current wire 219 passes through the second piston 213 and the end plate 217 and is connected to the control unit 3. The electrorheological fluid 215 is a fluid with adjustable viscosity. The viscosity of the electrorheological fluid 215 is adjusted by the control unit 3 applying a voltage to generate an electric field. The electrorheological fluid 215 changes its viscosity under the action of the electric field, thereby dynamically adjusting the damping force to achieve an efficient dissipation effect of vibration energy.

[0030] See also Figure 3 and Figure 5 The buckling-resistance support structure includes an outer tube 221, an inner core 222 and a connecting plate 223. The two ends of the inner core 222 are respectively connected to the connecting plate 223. The sleeve 211 is respectively arranged at the two ends of the inner core 222. The outer tube 221 is sleeved on the inner core 222 and the sleeve 211. The connecting plate 223 is close to the second port of the sleeve 211, and the second port of the sleeve 211 is closed. The outer tube 221 is an outer circular steel tube, and the inner core 222 is a cross steel core. The outer tube 221 is used to provide buckling constraints to prevent the internal steel core from buckling and instability. The inner core 222 is used to bear tensile and compressive loads and absorb vibration energy through plastic deformation.

[0031] Four electrorheological damping anti-buckling supports 2 connected in an "X" shape are installed between the two support columns 12 and the support plate 11 in the steel frame 1. One end of the electrorheological damping anti-buckling support 2 is connected to the support plate 11 or the support column 12 through a connecting plug 218, and the other end of the electrorheological damping anti-buckling support 2 is connected to the force distribution plate 5 through a connecting plug 218. The positions where the support plate 11 and the support column 12 are connected to the connecting plug 218 are respectively provided with hinged plates and bolts, and the connecting plug 218 is connected to the support plate 11 or the support column 12 through the hinged plates and bolts. Similarly, the connecting plug 218 is also connected to the force distribution plate 5 through a hinged plate and bolts.

[0032] Between the two support columns 12 and the support plate 11 in the steel frame 1, four electrorheological damping anti-buckling supports 2 connected in an "X" shape are symmetrically arranged on the left and right. The two electrorheological damping anti-buckling supports 2 located above are connected to the upper support plate 11 through a connecting plug 218, and the two electrorheological damping anti-buckling supports 2 located below are connected to the support columns 12 on both sides through a connecting plug 218.

[0033] The electrorheological damping anti-buckling brace 2 is used to enhance the seismic performance of the steel frame 1. Based on multiple energy dissipation mechanisms, vibration control is achieved through the synergistic effect of the electrorheological damper structure and the anti-buckling brace structure. The electrorheological damper structure uses the rheological properties of the electrorheological fluid 215 to actively dissipate velocity-related vibration energy by adjusting the damping force, and the anti-buckling brace structure absorbs displacement-related vibration energy through plastic deformation. The combination of the two realizes the separate dissipation of velocity energy and displacement energy, thereby significantly improving seismic performance and dynamic stability.

[0034] The data acquisition unit includes a vibration sensor, an acceleration sensor and a displacement sensor, which are evenly arranged at key nodes of the building. For example, the vibration sensor and the acceleration sensor are installed at the top and bottom of the building and at the end of the support plate 11 and the top of the support column 12 of each floor, and the displacement sensor is installed at the connection between the support plate 11 and the support column 12. The data acquisition unit is used to collect real-time vibration data of the building and send the building vibration data to the control unit 3.

[0035] The control unit 3 is used to apply voltage to the electrorheological fluid 215 to generate an electric field according to the vibration data of the building, and dynamically change the viscosity of the electrorheological fluid 215 by adjusting the intensity of the electric field to adjust the damping performance. The control unit 3 applies voltage to the electrorheological fluid 215 in the sleeve 211 through the current conductor 219 to generate an electric field in the electrorheological fluid 215. The control unit 3 can also use an adaptive control algorithm to predict future vibration trends according to the vibration intensity and adjust the damping performance in advance.

[0036] The control unit 3 controls the intensity of the electric field and the viscosity of the electrorheological fluid 215 by adjusting the voltage difference. When the vibration amplitude is small, the electric field applied by the control unit 3 is weak, and the viscosity of the electrorheological fluid 215 is low, allowing the electrorheological damping anti-buckling support 2 to provide a smaller damping force to reduce the rigid response of the building. When the vibration amplitude increases, the control unit 3 increases the intensity of the electric field, increases the viscosity of the electrorheological fluid 215, and improves the damping force, effectively limiting the deformation of the building and absorbing more vibration energy.

[0037] When the building is subjected to vibration load, the main structure vibrates, the support plate 11 and the support column 12 of the steel frame 1 vibrate, and the electrorheological damping anti-buckling support 2 connected to the support plate 11 or the support column 12 through the connecting plug 218 also vibrates accordingly. The end plate 217 of the electrorheological damper structure drives the first piston 212 and the second piston 213 to move. The electrorheological fluid 215 flows through the throttle hole 216 in the sleeve 211. The data acquisition unit collects vibration data and sends it to the control unit 3. The control unit 3 adjusts the electric field strength by changing the voltage to control the damping effect of the electrorheological damping anti-buckling support 2 to achieve vibration control.

[0038] The present invention adopts multiple energy dissipation mechanisms, which work together to disperse vibration energy step by step. In the electrorheological damper structure, the vibration energy during small and medium earthquakes is dissipated by adjusting the viscoelasticity of the electrorheological fluid 215. The inner core 222 of the buckling-resistance support structure enters plastic deformation during high-intensity earthquakes to absorb the energy generated by large vibrations. The support plate 11 and support column 12 of the steel frame 1 absorb the remaining energy through node energy dissipation and elastic deformation.

[0039] The photovoltaic curtain wall 4 is used to provide energy support for the control unit 3. As an important component, the photovoltaic curtain wall 4 integrates the photovoltaic power generation function and the structural support function, and uses solar energy resources to provide power support for the control unit 3, reducing the dependence on external power sources and improving independence and sustainability. The photovoltaic curtain wall 4 is also equipped with a backup power supply, which is used to provide backup energy for the control unit 3 in emergency situations. When an earthquake occurs, the photovoltaic curtain wall 4 ensures that the control unit 3 can continue to operate and supports real-time adjustment of the viscosity of the electrorheological fluid 215.

[0040] See also Figure 6 In the specific implementation process, when an earthquake occurs, the data acquisition unit collects earthquake vibration signals in real time, and transmits the vibration data to the control unit 3. The control unit 3 determines whether the building meets the control standard based on the earthquake vibration signals obtained in real time. When the control unit 3 determines that the vibration signal does not meet the control standard, it will perform dynamic adjustment, adjust the rheological properties of the electrorheological fluid 215 through the electrorheological damper structure, actively consume vibration energy, and thus achieve effective vibration control.

[0041] In addition, the performance of the supporting device is further optimized through the main structure vibration data collected in real time. After collecting more main structure vibration data, the control unit 3 uses the model to judge these data and further adjust the performance of the supporting device to ensure the stability and safety of the building under external vibrations such as earthquakes. If the vibration signal meets the control standard after adjustment, the adjustment is terminated. The present invention can respond to vibration signals in real time and achieve accurate vibration control through intelligent control methods, thereby improving the earthquake resistance and structural safety of the building.

[0042] In summary, the present invention adopts an assembled steel structure frame, with a high degree of component standardization, high on-site construction efficiency, and convenient installation, which conforms to the trend of modern building industrialization. The assembled design improves construction efficiency and scope of application, and can be adapted to high-rise buildings, bridges, large-span structures and other scenes with high requirements for vibration control.

[0043] The present invention combines the plastic energy dissipation of the anti-buckling support structure and the active adjustment advantages of the electrorheological damper structure. Through the synergistic effect of passive energy dissipation and active control, it can not only absorb displacement-related energy, but also adjust speed-related energy consumption in real time, adapt to various vibration conditions, and significantly improve vibration control efficiency and structural stability.

[0044] The present invention uses photovoltaic curtain walls to achieve efficient utilization of renewable energy. The excess electricity generated can be stored and equipped with a backup power supply to ensure the operational stability of the entire device. The power required by the entire intelligent assembled hybrid multi-energy consumption active vibration control support device can be fully provided by the photovoltaic curtain wall, saving electricity costs and achieving energy conservation and environmental protection.
