Description

Technical Field

[0001] The present invention belongs to the technical field of shock absorption and vibration isolation, and particularly relates to an intelligent vibration reduction control device and monitoring system for buildings. Background Art

[0002] Today, with the rapid development of social economy and industry, environmental vibrations caused by urban traffic, industrial production, etc. have had an undeniable impact on the safety and applicability of buildings, the lives and work of relevant residents, and even pose serious hazards to human health. This has attracted people's attention. Internationally, vibration pollution has been listed as one of the seven major environmental pollutions. People have been constantly seeking effective vibration reduction means, but the current vibration reduction means are single and have little effect.

[0003] In recent years, solid physics research has shown that when elastic waves in certain vibration frequency bands propagate in a periodic structure, due to the action of its internal periodic structure, the elastic waves in this frequency band cannot pass through the periodic structure. Therefore, by utilizing this characteristic of the periodic structure and applying it to machine vibration reduction research, more efficient vibration reduction can be achieved, thereby reducing the impact of machine vibration on buildings. However, the application of most periodic structures lacks intelligence and a feedback adjustment mechanism, making it difficult to perform large-scale and adjustable vibration reduction. Therefore, it is urgent to solve. Summary of the Invention

This system can not only isolate the impact of machine vibration on buildings, but also automatically adjust the properties of the corresponding most effective vibration reduction materials according to the current frequency of machine vibration, and can block vibration waves more controllably and over a larger range.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0013] Preferably, the coverage rate of the elastic waves in the vibration frequency band generated by the vibration of the machine by the first periodic structure is less than the coverage rate of the elastic waves in the vibration frequency band generated by the vibration of the machine by the second periodic structure.

[0014] Preferably, a Fourier transform data processing system is provided inside the controller.

[0015] Preferably, the driving motor is electrically connected to the controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In the present invention, a machine that generates vibrations is installed on a horizontal support frame. The two sides of the horizontal support frame are sleeved on two columns fixedly installed on the ground. At the same time, rollers are provided below the horizontal support frame, and at least two periodic structures with different bandgaps are provided below the rollers. The rollers are slidably connected to the upper surface of one of the periodic structures, and the side of the periodic structure is connected to a transmission track. Driven by the transmission track, the periodic structure can be replaced below the rollers, thereby improving the coverage rate of the bandgap of the periodic structure for the machine vibration wave. In addition, a magnet block is provided on the top of the machine. The magnet block faces the Hall element at a distance. The Hall element is electrically connected to a controller. A Fourier transform data processing system is provided in the controller. At the same time, the controller is also connected to the drive motor of the transmission track. When the controller determines that the frequency of the vibration wave generated by the vibration of the machine has exceeded or is about to exceed the range of elastic waves that can be covered by the bandgap of the first periodic structure, the controller controls the drive of the transmission track, and can push the first periodic structure and the second periodic structure to move horizontally along the bottom of the machine. Thus, the first periodic structure at the bottom of the machine is replaced by the second periodic structure, so as to better isolate the vibration wave generated by the machine vibration from the building, and play a good protective effect on the building.

[0018] (2) In the present invention, by providing a horizontal support frame and columns, the horizontal support frame is sleeved on the columns, and rollers are provided at the bottom of the horizontal support frame, so that when the periodic structure at the bottom of the horizontal support frame is moved and replaced, the machine will not move horizontally and will not affect the operation of the machine.

Then, the magnetic field change information is processed by the Fourier transform data processing system in the controller. Finally, the drive motor of the transmission track is controlled by the processed data, realizing the replacement of different periodic structures at the bottom of the machine. Such a design not only solves the influence of the machine vibration wave on the building, but also realizes intelligent adjustment, which is convenient and efficient and plays a better protective effect on the building.

[0028] Embodiment

[0029] As Figure 1 shown, an intelligent vibration damping control device and monitoring system for a building, characterized in that it includes machine A; machine A is installed on a limiting component, and the limiting component is installed on the ground, and the limiting component is used to limit the horizontal movement of machine A. A vibration isolation component is arranged below the limiting component, and the vibration isolation component is used to isolate the vibration of machine A, and the vibration isolation component is slidably connected to the lower part of the limiting component, and the vibration isolation component is connected to a moving component, and the moving component is installed on the ground and drives the vibration isolation component to move horizontally;

[0030] It also includes a magnet block 41 and a Hall element 31; the Hall element 31 is arranged on the limiting component; the magnet block 41 is installed at the top of machine A and is spaced opposite to the Hall element 31; the controller 70 is electrically connected to both the Hall element 31 and the moving component, and the Hall element 31 transmits the magnetic field vibration information of the magnet block 41 on machine A to the controller 70, and a Fourier transform data processing system is provided inside the controller 70.

[0031] The Fourier transform data processing system in the controller 70 determines whether the elastic wave in the vibration frequency band generated by the vibration of machine A can be isolated by the vibration isolation component through the magnetic field vibration information of the magnet block 41. If it cannot be isolated, it controls the moving component to replace the vibration isolation component below machine A, so as to avoid the impact of the elastic wave generated by the vibration of machine A on the buildings near machine A.

[0032] In actual implementation, the seismic isolation component consists of a first periodic structure 51 and a second periodic structure 52, and the coverage rate of the elastic waves in the vibration frequency band generated by the vibration of machine A by the first periodic structure 51 is less than that of the elastic waves in the vibration frequency band generated by the vibration of machine A by the second periodic structure 52. The first periodic structure 51 and the second periodic structure 52 are both horizontally placed on the ground to isolate the elastic waves generated by the vibration of machine A and prevent the elastic waves from affecting the buildings near machine A. The sides of the first periodic structure 51 and the second periodic structure 52 are both connected to the moving component, and the tops of the first periodic structure 51 and the second periodic structure 52 are slidably connected to the limiting component at the bottom of machine A.

[0033] The limiting component consists of a horizontal support frame 10 and two vertical columns 20. The two vertical columns 20 are respectively vertically arranged on both sides of machine A, the bottom ends of the vertical columns 20 are fixedly connected to the ground, and the top ends of the vertical columns 20 are connected to both ends of the detection bridge 30. The detection bridge 30 is arranged as an arc-shaped horizontal rod, both ends of the horizontal rod are respectively connected to the top ends of the two vertical columns 20, and the Hall element 31 is installed on the horizontal rod.

[0034] Machine A is installed above the horizontal support frame 10. Both sides of the horizontal support frame 10 are sleeved on the vertical columns 20, and the sleeved parts can slide up and down along the vertical direction of the vertical columns 20. A roller 11 is arranged below the horizontal support frame 10, and the roller 11 is placed on the top of the first periodic structure 51 or the second periodic structure 52.

[0035] The moving component consists of a gear 61 and a transmission track 62. The gear 61 is installed on the base of the vertical column 20 and is connected to the rotating shaft of the driving motor arranged inside the vertical column 20. The driving motor is electrically connected to the controller 70.

[0036] The transmission track 62 includes a sliding track and a transmission strip. There are two sliding tracks, which are respectively located on both sides of the first periodic structure 51 and the second periodic structure 52 and are connected to the ground by bolts; the transmission strip is clamped in the sliding track and forms a sliding connection with it.

[0037] A transmission tooth is arranged on one side of the transmission strip. The transmission tooth forms a gear transmission with the gear 61, and the other side of the transmission strip is a plane, and the plane is connected to the sides of the first periodic structure 51 and the second periodic structure 52.

[0038] When the controller 70 receives the vibration information of the magnetic field of the magnet block 41 above machine A transmitted by the Hall element 31, the Fourier transform data processing system in the controller 70 processes the magnetic field vibration information. If the controller 70 determines that the frequency of the vibration wave generated by the vibration of machine A has exceeded or is about to exceed the range of elastic waves that the first periodic structure 51 can cover, the controller 70 controls the driving motor to rotate the gear 61, which can then push the first periodic structure 51 and the second periodic structure 52 to move horizontally along the bottom end of machine A. As a result, the first periodic structure 51 at the bottom end of machine A is replaced by the second periodic structure 52, thus better isolating the vibration wave generated by the vibration of machine A from the building and achieving a good protection effect on the building.
