Description

Technical Field

[0001] This utility model relates to the field of seismic isolation technology, and more specifically, to a vibration isolation and seismic protection platform for power equipment. Background Technology

[0002] Small electrical equipment (such as reactors) often exhibit vibration during operation. This vibration not only affects comfort but can also adversely impact the safety of building structures in special circumstances.

While this method is theoretically effective, improper handling of certain details during implementation can lead to poor vibration isolation. Furthermore, existing equipment lacks protection mechanisms in the event of accidental loads, such as strong earthquakes, making it impossible to ensure the safety of the equipment.

Example

[0029] This embodiment provides a vibration isolation and seismic protection platform 100 for power equipment, referring to... Figure 1 As shown, it includes a base 110, and the side walls of the base 110 are provided with a plurality of elastic seats 120 and a plurality of limiting seats 130 at intervals.

[0030] A flexible connector 111 is provided on the top of the base 110 for connecting to the device above. For example... Figure 2 and Figure 3 As shown, the elastic seat 120 includes an upper support plate 121 and a lower support plate 122. The upper support plate 121 is connected to the base 110, and the lower support plate 122 is connected to the lower structure 200. An elastic connector 111 is provided between the upper support plate 121 and the lower support plate 122. Multiple elastic seats 120 support the base 110, forming an isolation gap between the bottom surface of the base 110 and the lower structure 200. The lower structure 200 can be a ground, floor slab, or other structure, and can be installed on a suitable horizontal surface, allowing for a certain degree of tilt. During slight vibration, the elastic seat 120 can effectively absorb vibration and maintain the stability of the base 110.

[0031] like Figure 4 and Figure 5 As shown, the limiting seat 130 includes an upper limiting plate 131 and a lower limiting plate 132. The upper limiting plate 131 is connected to the base 110, and the lower limiting plate 132 is connected to the lower structure 200. The upper limiting plate 131 and the lower limiting plate 132 are spaced apart and connected by threaded parts. In the event of accidental load, the limiting seat 130 can restrict the movement of the base 110, ensuring the safety of the equipment above the base 110.

[0032] like Figure 3 As shown, the elastic connector 111 includes a spring 123, and nested outer cylinder 124 and inner cylinder 125. The outer cylinder 124 is connected to the upper support plate 121, and the inner cylinder 125 is connected to the lower support plate 122. The outer cylinder 124 and inner cylinder 125 together form an inner cavity, which is filled with damping fluid. The spring 123 is disposed within the inner cavity. The spring 123 achieves flexible isolation between the base 110 and the upper isolated equipment and the lower structure 200, reducing the natural frequency of the upper structure to achieve the effect of vibration isolation. During vibration isolation, the damping fluid absorbs the kinetic energy of the spring 123 and converts it into heat energy, thus dissipating vibration energy. An elastic pad 126 is provided at the bottom of the lower support plate 122. The elastic pad 126 can further buffer the lower support plate 122 and the lower structure 200, enhancing the absorption of vibration.

[0033] Furthermore, the upper support plate has a downwardly protruding first limiting ridge 1211, and the lower support plate has an upwardly protruding second limiting ridge 1221. The spring 123 is sleeved on the outside of the first limiting ridge 1211 and the second limiting ridge 1221. The first limiting ridge 1211 and the second limiting ridge 1221 are annular, and their outer diameter is slightly smaller than the inner diameter of the spring 123, which can limit the horizontal misalignment of the spring 123.

[0034] like Figure 4 and Figure 5As shown, a pair of vertical support plates 1321 are provided on both sides of the lower limit plate 132. The pair of vertical support plates 1321 are located at the bottom of the lower limit plate 132 and are fixedly connected to the lower structure 200. The lower limit plate 132 and the pair of vertical support plates 1321 form an inner frame. A pair of protective plates 1311 are provided on both sides of the upper limit plate 131. The pair of protective plates 1311 are located at the bottom of the upper limit plate 131. The upper limit plate 131 and the pair of protective plates 1311 form an outer frame. The outer frame is fitted over the inner frame, and a gap is formed between the two frames. In addition to their respective supporting and protective functions, the vertical support plates 1321 and the protective plates 1311 can limit the large-scale horizontal displacement of the base 110 under accidental loads by using the abutment limit between them. The vertical support plate 1321 has a buffer pad 133 on the side facing the protective plate 1311, which can provide a certain degree of buffering when the vertical support plate 1321 and the protective plate 1311 come into contact.

[0035] In addition, the upper limit plate 131 has a back plate 1312 on the side facing the base 110. The back plate 1312 is located between a pair of protective plates 1311 and is connected to the base 110, increasing the contact area between the outer frame and the base 110 and improving connection stability. The lower limit plate 132 has a rear support plate 1322 on the side facing the base 110. The rear support plate 1322 is located between a pair of vertical support plates 1321. By using the abutment and limiting action between the rear support plate 1322 and the back plate 1312, horizontal displacement in another direction can be restricted. Similarly, the rear support plate 1322 also has a buffer pad 133 on the side facing the back plate 1312.

[0036] The threaded components include a tension bolt 134 and a tension nut 135. The upper limit plate 131 and the lower limit plate 132 are respectively provided with a first mating hole and a second mating hole for engaging with the tension bolt 134. The tension bolt 134 passes through the first and second mating holes and extends into the inner frame. The tension nut 135 is located inside the inner frame and is threadedly connected to the tension bolt 134. The tension nut 135 maintains a certain distance from the bottom of the lower limit plate 132, and the size of the distance can be adjusted according to specific needs. When an accidental load occurs, if the upper limit plate 131 and the lower limit plate 132 experience vertical displacement (i.e., the upper limit plate 131 moves upward), it will cause the tension bolt 134 to move upward synchronously until the tension nut 135 abuts against the lower limit plate 132. The tension nut 135 can limit the continued upward movement of the upper limit plate 131, thereby maintaining the safety of the equipment above.

[0037] Furthermore, the threaded component also includes a lock nut 136, which is located below the tension nut 135 and is threadedly connected to the tension bolt 134. The lock nut 136 is tightened to abut against the tension nut 135, thereby reinforcing the tension nut 135.

[0038] like Figure 1 As shown, the base 110 includes a long, narrow base body 112 and a pair of extensions 113 extending to both sides along the width of the base body 112. The base body 112 and the extensions 113 form a cross-shaped structure, thereby achieving better stability. The base 110 is constructed from channel steel and is internally filled with mass blocks 114 to increase its self-weight. There are four elastic seats 120, located at the four corners of the base body 112; and four limiting seats 130, with one limiting seat 130 on each side of each extension 113, located at the end of the extension 113 furthest from the base body 112. This distribution better balances the forces and provides better vibration isolation.

[0039] The base body 112 has connecting plates 115 at each of its four corners, and the connecting plates 115 are connected to the extensions 113. The extensions 113 correspond one-to-one with the elastic seats 120, and the middle part of the extensions 113 is fixedly connected to the upper support plate 121 by connecting bolts. The connecting plates 115 are connected to both the base body 112 and the extensions 113, which serves to strengthen and reinforce the connection, improving its reliability and stability.

[0040] In summary, this utility model embodiment provides a vibration isolation and seismic protection platform 100 for power equipment, which includes a base 110. Multiple elastic seats 120 are spaced apart on the sidewalls of the base 110. Each elastic seat 120 includes an upper support plate 121 and a lower support plate 122. The upper support plate 121 is connected to the base 110, and the lower support plate 122 is connected to the lower structure 200. An elastic connector 111 is provided between the upper support plate 121 and the lower support plate 122. The multiple elastic seats 120 support the base 110, forming an isolation gap between the bottom surface of the base 110 and the lower structure 200. Multiple limiting seats 130 are also spaced apart on the sidewalls of the base 110. Each limiting seat 130 includes an upper limiting plate 131 and a lower limiting plate 132. The upper limiting plate 131 is connected to the base 110, and the lower limiting plate 132 is connected to the lower structure 200. The upper limiting plate 131 and the lower limiting plate 132 are spaced apart and connected by threaded components. During mild vibrations, the elastic seat 120 can effectively absorb the vibrations and maintain the stability of the base 110; while in the event of an accidental load, the limiting seat 130 can restrict the movement of the base 110 and ensure the safety of the equipment above the base 110.
