Description

Technical Field

[0001] This utility model relates to combined anti-seismic bolts, and more particularly to an anti-seismic bolt for power equipment. Background Technology

[0002] Earthquakes possess powerful energy release and seismic effects. They can impact, vibrate, and displace equipment and buildings, leading to damage, breakage, tilting, or even failure. Therefore, the impact of earthquakes on equipment should be taken seriously, and corresponding vibration reduction designs should be implemented to ensure stable equipment operation. Highly flexible power equipment has low damping and is prone to excessive vibration under external excitation, which not only causes malfunctions and shutdowns but also reduces the fatigue performance of the equipment itself. Therefore, vibration control of power equipment has become one of the key technical challenges that the new energy industry urgently needs to solve. Currently, vibration reduction technology for power equipment has received considerable research attention and yielded valuable results, but there are still shortcomings in vibration control. Therefore, a seismic-resistant bolt for power equipment is proposed.

[0003] The equipment's vibration damping design enhances its resistance and flexibility to earthquake-induced shocks and vibrations. Through rigorous structural design, high-quality material selection, and proper installation methods, the equipment possesses sufficient rigidity, strength, and stability to withstand strong earthquake vibrations. Furthermore, the vibration damping design must fully consider factors such as the equipment's own weight and operating load, vibration absorption, and damping measures to minimize earthquake damage to the equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide an anti-vibration bolt for power equipment. Its unique self-resetting performance improves the energy dissipation capacity and service life of ordinary bolts, and can significantly reduce the impact of environmental factors such as earthquakes, wind vibrations or other vibrations on facility vibration, thus ensuring the safety of personnel and property.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A seismic-resistant bolt for power equipment, by incorporating a self-resetting module, enables ordinary seismic-resistant bolts to possess self-resetting capabilities. This product employs a unique structure and materials, effectively absorbing and dispersing energy from earthquakes, wind vibrations, or other vibrations while achieving self-resetting, thus reducing the vibration and displacement of structures or equipment. The bolt includes a threaded rod, an energy-dissipating element and an inner sleeve fitted onto the threaded rod, and an outer sleeve fitted around the energy-dissipating element and the inner sleeve. Multiple nuts are fitted onto the outer side of the inner sleeve and the lower outer side of the threaded rod. A bolt head is located at the top of the threaded rod, and a self-resetting module is positioned between the bolt head and the outer sleeve. The outer diameter of the threaded rod is smaller than the inner diameter of the inner sleeve, the energy-dissipating element, and the upper cap of the outer sleeve, and the inner side of the outer sleeve and the inner and outer sides of the energy-dissipating element are smooth surfaces to allow the threaded rod to slide. The inner diameter of the outer sleeve is larger than the outer diameter of the energy-dissipating element and the inner sleeve, allowing the outer sleeve to slide. The outer side of the inner sleeve is threaded for connection with the outer sleeve, and the inner side of the inner sleeve is a sliding surface. These anti-seismic bolts feature self-resetting, easy disassembly and assembly, and can be configured to achieve vibration reduction and energy dissipation effects under various requirements.

[0007] A further improvement of this invention is that the energy-consuming element includes, but is not limited to, metal or rubber.

[0008] A further improvement of this utility model is that the self-resetting module can be connected to the outer sleeve and bolt head by welding or bolting.

[0009] A further improvement of this utility model is that the self-resetting module includes, but is not limited to, a spring, a disc spring, a memory metal, or rubber.

[0010] A further improvement of this invention lies in the fact that the seismic bolt has a self-resetting function. After an earthquake, wind vibration, or other vibration, it can quickly return to its original position through the self-resetting module. The residual deformation of the energy-dissipating element of the seismic bolt is very small, thereby improving the energy dissipation capacity and service life of the seismic bolt, and greatly enhancing its energy dissipation performance and durability. Depending on the load-bearing capacity requirements, the self-resetting capability of the bolt can be improved by changing the material and number of the self-resetting module.

[0011] Compared with the prior art, this utility model has outstanding self-resetting features, higher energy consumption capacity, and longer service life.

[0012] The beneficial effects of this utility model are: the seismic bolt has self-resetting performance under earthquakes, wind vibrations or other vibrations, the energy dissipation capacity and durability of the seismic bolt are greatly improved, it is easy to install, has a good vibration reduction effect, occupies little space, does not require changes to the main structure construction method, and is easy to maintain.

[0019] like Figure 1 As shown, a seismic-resistant bolt for power equipment not only resists earthquakes and wind vibrations and absorbs and disperses impact forces, but also has a self-resetting function, significantly reducing the destructive impact of earthquakes, wind vibrations, and other vibrations on the equipment. With the help of this seismic-resistant bolt, the equipment's earthquake and wind resistance is improved, while also providing more stable and reliable protection for the power facilities it is attached to.

[0020] This seismic-resistant bolt consists of a self-resetting module, a bolt, a threaded rod, a sleeve, a nut, and an energy-dissipating element. The self-resetting component is made of a spring, disc spring, shape memory alloy, or metal. The bolt includes a nut and a bolt head. The sleeve is assembled from an outer sleeve and an inner sleeve, used to dissipate energy through the energy-dissipating element. An energy-dissipating element 7 and an inner sleeve 3 are fitted onto the threaded rod 2. An outer sleeve 4 is fitted around the energy-dissipating element 7 and the inner sleeve 3. Multiple nuts 6 are fitted onto the outer side of the inner sleeve 3 and the lower outer side of the threaded rod 2. A bolt head 1 is located at the top of the threaded rod 2. A self-resetting module 8 is located between the bolt head 1 and the outer sleeve 4. This seismic-resistant bolt has a self-resetting function, and multiple self-resetting modules can be added as needed to adjust the bolt's self-resetting performance and energy dissipation capacity. Compared to traditional seismic bolts, this seismic bolt features a self-resetting function, rapidly returning to its original position after earthquakes, wind-induced vibrations, or other vibrations. This minimizes residual deformation of the energy-dissipating components, thereby enhancing the bolt's energy dissipation capacity and service life, significantly improving its energy dissipation performance and durability. This seismic bolt boasts self-resetting capabilities, convenient assembly and disassembly, and easy installation. The self-resetting function is achieved by connecting a self-resetting module in parallel to the energy-dissipating component. Different degrees of self-resetting effect can be achieved by configuring self-resetting components of varying materials and quantities. In earthquake, wind-induced vibration, or other vibration environments, this seismic bolt absorbs and disperses impact forces and vibrations while reducing residual strain through the self-resetting module, thus mitigating the impact of earthquakes, wind-induced vibrations, or other vibrations on equipment. By adopting this seismic bolt, the vibration reduction and wind resistance performance of electrical facilities is improved, while also enhancing the safety of related supporting facilities. The seismic bolt has a simple structure, with robust and reliable connections between components, ensuring efficient vibration reduction and seismic resistance even under vibration conditions, facilitating its widespread application.

[0021] The self-resetting module of the seismic-resistant bolt can be composed of different materials and different numbers of self-resetting elements. Adjusting the material and number of the self-resetting module changes the self-resetting performance of the seismic-resistant bolt under earthquakes, wind vibrations, or other vibrations. The self-resetting module is connected to the bolt head 1 and the outer sleeve 4 by bolts or welding. When the equipment vibrates, the seismic-resistant bolt can quickly return to its original position after earthquakes, wind vibrations, or other vibrations. The residual deformation of the energy-dissipating elements of the seismic-resistant bolt is very small, thereby improving the energy dissipation capacity and service life of the seismic-resistant bolt, greatly enhancing its energy dissipation performance and durability.

[0022] The springs, disc springs, shape memory metals, or rubbers in the self-resetting module can be arranged in multiples around the perimeter or through the screw.

[0023] Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention as defined by the appended claims.
