DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is a structural diagram of a shock-absorbing and seismic isolation mounting structure for a building provided by an embodiment of the present invention, including a vibration sensor 3 and a controller 20. The shock-absorbing and seismic isolation mounting structure for a building also includes a base 4, on which a protective cover 8 is fixedly installed, and an exciter 14 is fixedly installed in the protective cover 8. A dynamic damping mechanism is fixedly connected to the protective cover 8, and the dynamic damping mechanism is used to suppress the vibration of the ceiling 1. The controller 20 is electrically connected to the dynamic damping mechanism, the vibration sensor 3 and the exciter 14 through a cable 2.

[0018] In an embodiment of the present invention, during installation, the base 4 is installed on the ceiling 1. When in use, the position of the earthquake source is detected by evenly distributed vibration sensors 3, and multiple exciters 14 are controlled by the controller 20 to vibrate to offset the vibration caused by the earthquake source. On this basis, in order to avoid the vibration of the ceiling 1 causing the vibration of the suspended ceiling, a dynamic damping mechanism is provided. The dynamic damping mechanism automatically adjusts the vibration filtering frequency according to the vibration of the earthquake source, thereby achieving accurate vibration filtering and reducing noise generation.

[0019] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the dynamic damping mechanism includes a mounting tube 5, which is fixedly mounted on the protective cover 8, an electromagnet 15 is fixedly mounted in the inner cavity of the mounting tube 5, an end of the mounting tube 5 away from the protective cover 8 is detachably connected to a tube cover 12, a connecting rod 13 is arranged in the mounting tube 5, an end of the connecting rod 13 close to the protective cover 8 is fixedly connected to a baffle, a dynamic damping block 17 is sleeved on the outer periphery of the connecting rod 13, an end of the baffle close to the electromagnet 15 is fixedly connected to a magnetic block 16, the connecting rod 13 passes through the tube cover 12, and the end away from the magnetic block 16 is fixedly connected to a connecting seat 6, and the connecting seat 6 is connected to the ceiling through bolts 7.

[0020] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the end of the connecting rod 13 away from the magnetic block 16 is fixedly connected to the first damper 9, the first damper 9 is fixedly connected to the second damper 10, the second damper 10 is fixedly connected to the third damper 11, the connecting seat 6 is fixedly installed on the third damper 11, and the first damper 9 is connected to the cylinder cover 12 by a spring 19.

[0021] In this embodiment, the first damper 9, the second damper 10 and the third damper 11 are respectively a low-frequency damper, a medium-frequency damper and a high-frequency damper, and their damping ranges are 1-5Hz, 5-30Hz and 30-100Hz, respectively, which are used to filter vibrations of different frequencies; when in use, the vibration of the ceiling 1 is detected by the vibration sensor 3, and the controller 20 determines the location of the source according to the detection data of each vibration sensor 3, and then controls the operation of the exciter 14 in the corresponding area, and drives the ceiling 1 to vibrate through the exciter 14 to offset the vibration generated by the source. In order to reduce the transmission of vibration, according to the vibration condition of the ceiling 1, the electromagnet 15 is started to generate a magnetic field through the electromagnet 15. The magnetic field generated by the electromagnet 15 will repel the magnetic block 16, and the magnetic block 16 is installed on the baffle, so the baffle has There is a tendency to move away from the electromagnet 15, the baffle will gradually approach the cylinder cover 12, and the distance between the cylinder cover 12 and the baffle will be reduced, then the dynamic damping block 17 will be squeezed, resulting in a change in its density. Due to the change in density, its damping range will also change accordingly. Therefore, its damping range can be actively adjusted according to the vibration information of the earthquake source to achieve precise damping control and suppress the transmission of vibration to the greatest extent; when the vibration of the earthquake source is large, such as its amplitude exceeds the preset value, it is difficult to eliminate its transmission only through the damper. At this time, the magnetic pole of the electromagnet 15 is changed to make it adsorb the baffle, then the baffle will move to the side close to the electromagnet 15, and the baffle is in a state of being separated from the dynamic damping block 17. At this time, only the cylinder cover 12 is directly connected to the first damper 9 through the spring 19, so it will greatly reduce the direct transmission of vibration and play a role in seismic isolation.

[0022] In one embodiment of the present invention, an adjustment gasket 18 is provided between the cylinder cover 12 and the dynamic damping block 17 .

[0023] In this embodiment, since different installation heights require controlling the distance between the base 4 and the connecting seat 6, an internal thread is provided on the cylinder cover 12, and an external thread is provided on the mounting cylinder 5. The two are connected by threads. When the distance between the base 4 and the connecting seat 6 needs to be adjusted, it can be achieved by rotating the cylinder cover 12. Since the size of the dynamic damping block 17 is fixed, an adjusting gasket 18 can be provided in the mounting cylinder 5, and the gap can be filled by adding multiple adjusting gaskets 18.

[0024] In one embodiment of the present invention, when the shock-absorbing and seismic isolation installation structure for buildings is in operation, the vibration information of the ceiling 1 is recorded by the vibration sensor 3, the frequency distribution bandwidth of the vibration information is identified, and the electromagnet 15 is energized according to the frequency distribution bandwidth. The electromagnet 15 repels the magnetic block 16, and the magnetic block 16 squeezes the dynamic damping block 17 through the baffle. The density of the dynamic damping block 17 is changed by squeezing, and the vibration is filtered by the dynamic damping block 17.

[0025] In this embodiment, a plurality of vibration sensors 3 are installed on the ceiling 1. Since the ceiling 1 is a plane, a plurality of vibration sensors 3 are set on the plane. The vibration of the ceiling 1 will be transmitted to the surroundings with the earthquake source as the center. During the transmission process, the vibration energy gradually decreases. When vibration occurs, three vibration sensors 3 with the strongest vibration signals are selected. Based on the installation position relationship of the vibration sensors 3, a two-dimensional coordinate system is constructed. Then the coordinates of each vibration sensor 3 are determined accordingly. The distance between any two vibration sensors 3 is known. Then the coordinates of the earthquake source are set to (x, y). Then the distances between the earthquake source and the three vibration sensors 3 with the strongest vibration signals can be calculated, which are L1, L2 and L3 respectively. According to the attenuation formula of the vibration intensity ,in, is the vibration intensity at the source, r is the distance between the source and the vibration sensor 3, and n is the attenuation coefficient, which can be 2. Three sets of equations are constructed to obtain the three unknowns, x, y and The solution is performed to obtain the position and intensity of the earthquake source, and the frequency of the vibration can be obtained according to the vibration sensor 3. According to its position, the adjacent exciter 14 is mobilized. According to the position of the exciter 14, the vibration intensity and frequency information when the vibration generated by the earthquake source is transmitted to the corresponding exciter 14 can be calculated, and the corresponding exciter 14 can be controlled to vibrate, thereby offsetting the vibration of the ceiling 1 caused by the earthquake source. In order to suppress the vibration of the exciter 14 from being transmitted to the suspended ceiling below, the dynamic damping block 17 and a plurality of dampers can be used to avoid the transmission of vibration. When the vibration of the ceiling 1 is not large, the exciter 14 can be disabled, and the vibration of the suspended ceiling caused by the slight vibration of the ceiling 1 can be eliminated only by the dynamic damping block 17 and a plurality of dampers, so as to play a role in seismic isolation and shock reduction.

[0026] The present invention also provides an installation method for the above-mentioned shock-absorbing and seismic isolation mounting structure for a building, the method comprising fixing the shock-absorbing and seismic isolation mounting structure for a building on the ceiling 1 through a base 4, and installing multiple groups of shock-absorbing and seismic isolation mounting structures for a building on the ceiling 1 in a matrix distribution manner, with four shock-absorbing and seismic isolation mounting structures for a building as a group to form a minimum rectangle, and a vibration sensor 3 is arranged at the center of the rectangle, the vibration sensor 3 is connected to the controller 20 through a cable 2, the controller 20 is electrically connected to all the shock-absorbing and seismic isolation mounting structures for a building, and the spacing between adjacent shock-absorbing and seismic isolation mounting structures for a building in the same row or column is the same.
