The built-in transformer substation is used as a module to be built into other functional buildings, and meanwhile, the functions of the built-in buildings, such as living or business, are reserved, so that the land requirement of the transformer substation in the urban dense area is relieved. In the related art, a vibration isolation device is arranged between the substation equipment and a bearing surface where the substation equipment is located, so that the influence of earthquake action on the substation equipment is avoided, and meanwhile vibration noise generated by the operation of the substation equipment is controlled. However, in the built-in substation, on one hand, after the substation equipment goes upstairs, the vertical movable range of the vibration isolation device needs to be further improved because of the amplifying effect of the building where the substation equipment is located on the earthquake. On the other hand, the building in which the vibration isolator is positioned has control requirements on environmental vibration and noise, and the vibration isolation performance of the vibration isolator needs to be further improved.
The vibration isolation devices commonly used at present are mainly divided into rubber vibration isolators and metal vibration isolators. The rubber vibration isolator has good vibration isolation performance, and can realize vibration control of substation equipment so as to meet the vibration stability requirement of the equipment and the vibration and noise control requirement of a building where the equipment is located. However, the rubber vibration isolator has a small vertical movement range, and can possibly cause adverse effects when in extreme loads such as earthquake, so that the rubber vibration isolator cannot adapt to the amplification effect of buildings on the earthquake. The vertical movable range of the metal vibration isolator is larger than that of the rubber vibration isolator, and the metal vibration isolator can adapt to the amplifying effect of buildings on earthquake. However, the vibration isolation performance of the metal vibration isolator is weaker than that of the rubber vibration isolator, and the current metal vibration isolator (such as a spring type vibration isolator, a steel wire rope vibration isolator and the like) cannot meet the control requirements of buildings on vibration and noise. In summary, when the current vibration isolation device is applied to an attached transformer substation, the current vibration isolation device cannot meet the control requirements of buildings on vibration and noise while adapting to the amplification effect of the buildings on the earthquake.
Aiming at the problems in the related art, the embodiment of the application provides a vibration isolation device which is suitable for the amplifying effect of a building on the earthquake action and meets the control requirement of the building on vibration and noise.

In some embodiments, referring to fig. 1 to 3, embodiments of the present application provide a vibration isolation apparatus 100 including a first support plate 10, a second support plate 20, and a vibration isolation structure 30. The first support plate 10 is used for carrying a to-be-supported member (not shown), the second support plate 20 is arranged at intervals from the first support plate 10 along a first direction (z direction in the figure), and the second support plate 20 is used for being arranged on a carrying surface. The vibration isolation structure 30 is respectively connected to the first support plate 10 and the second support plate 20 at two sides of the first direction, the vibration isolation structure 30 includes a plurality of vibration isolators 31, and each vibration isolator 31 includes a hollow cylinder 311 and an energy dissipation layer 312 coated on the surface of the hollow cylinder 311. The center axis of the vibration isolator 31 is perpendicular to the first direction, and the vibration isolator 31 is configured to be elastically deformable in the radial direction thereof. The two axial sides of the hollow cylinder 311 are respectively provided with a plurality of first notches 3111 and a plurality of second notches 3112, and the first notches 3111 and the second notches 3112 are alternately arranged along the circumferential direction of the hollow cylinder 311, so as to form a vibration propagation path extending in a meandering manner on the hollow cylinder 311. Optionally, the first direction is parallel to the direction of gravity.
When the vibration isolation device 100 is applied to an attached transformer substation, the first support plate 10 carries transformer substation equipment, the second support plate 20 is arranged on a bearing surface where the transformer substation equipment is located in a building, the vibration isolation structure 30 elastically connects the first support plate 10 and the second support plate 20, and the vibration isolator 31 can elastically deform along the radial direction of the vibration isolator 31 to provide a vertical movable range required by the vibration isolation device 100 during working. In the vibration isolator 31, a tortuous vibration propagation path is formed on the hollow cylinder 311 through a first notch 3111 and a second notch 3112 provided on the hollow cylinder 311, and dissipation of energy in the vibration propagation process is achieved through the energy dissipation layer 312 coated on the surface of the hollow cylinder 311. As such, when the distance between the first support plate 10 and the second support plate 20 is fixed, the propagation path through which the vibration passes in the process of being transferred between the substation equipment and the building is longer, and the dissipated energy is more, so that the amplitude of the transferred vibration is lower. The vibration isolation device 100 has a wide vertical movement range and good vibration isolation effect, can adapt to the amplification effect of the building on the earthquake effect, and can meet the control requirement of the building on vibration and noise.
In addition, in the vibration isolation device 100 of the present application, by setting the number and arrangement of the vibration isolators 31 in the vibration isolation structure 30 and the parameters such as the thickness, the axial dimension, the radial dimension, etc. of the hollow cylinder 311 in each vibration isolator 31, the vertical rigidity of the vibration isolation device 100 can be adjusted to avoid the excellent frequency range of the earthquake motion, thereby avoiding the vibration isolation device 100 from resonating with the earthquake motion. Alternatively, in some embodiments, the thickness of the hollow cylinder 311 is 5mm, and the axial and radial dimensions of the hollow cylinder 311 are 200mm.
It should be noted that, the application scenario of the vibration isolation device 100 of the present application is not limited to an attached transformer substation, that is, the object to be supported is not limited to transformer substation equipment, and the bearing surface is not limited to a building where the transformer substation equipment is located. In other embodiments, the vibration isolation apparatus 100 may also be used to support other devices having vibration isolation requirements, which are not limited in this application.
In some embodiments, the hollow cylinder 311 is made of spring steel, and the energy dissipation layer 312 is made of polymer damping material, such as polyacrylate, polyurethane, epoxy, butyl rubber, nitrile rubber, and the like. The high molecular damping material can convert mechanical vibration energy or acoustic energy into thermal energy to dissipate and can prevent or lighten the damage of the mechanical vibration to the component. In addition, the energy dissipation layer 312 is coated on the surface of the hollow cylinder 311, so that the hollow cylinder 311 can be isolated from air to reduce corrosion of spring steel, thereby prolonging the service life of the hollow cylinder 311 and keeping the performance stable.
In some embodiments, hollow cylinder 311 is formed from sheet spring steel end-to-end. Specifically, the sheet spring steel is provided with a first notch 3111 and a second notch 3112 at two sides in the width direction, the first notch 3111 and the second notch 3112 are alternately arranged along the length direction of the spring steel, and the spring steel is connected end to form the hollow column 311 shown in fig. 2. It will be appreciated that when the spring steel length is fixed, the smaller the dimensions of the first gap 3111 and the second gap 3112, the smaller the gap between adjacent first gap 3111 and second gap 3112, the more the number of bends in vibration propagation; the larger the width of the spring steel, the longer the linear propagation distance at the time of vibration propagation. Therefore, by reducing the sizes of the first gap 3111 and the second gap 3112, the gaps between the adjacent first gap 3111 and second gap 3112, and increasing the width of the spring steel, the total length of the vibration propagation path can be increased, and the vibration amplitude after transmission can be reduced, so that vibration control of the substation equipment is realized to meet the vibration stability requirement of the equipment itself and the vibration and noise control requirement of the building where the equipment is located.
Fig. 4 shows a schematic structural diagram of a barrier unit in one embodiment of the present application.
In some embodiments, referring to fig. 1 and 4, the vibration isolation structure 30 includes at least one vibration isolation layer unit. When the number of the vibration isolation layer units is plural, the plural vibration isolation layer units are arranged along the first direction. Each vibration isolation layer unit comprises a plurality of vibration isolators 31, and the central axes of the vibration isolators 31 are positioned on the same reference plane A perpendicular to the first direction. In this way, under the condition that the structure of the single vibration isolator 31 is determined, the overall height, the vertical movable range and the vertical rigidity of the vibration isolation structure 30 can be controlled by setting the number of the vibration isolation layer units and the number of the vibration isolators 31 in each vibration isolation layer unit so as to adapt to the vibration isolation design requirements of different transformer substation equipment and buildings where the transformer substation equipment is located, thereby reducing the manufacturing difficulty of the vibration isolation device 100 and improving the applicability of the vibration isolation device 100.
In some embodiments, in each vibration isolation layer unit, the central axis of one portion of the vibration isolator 31 is parallel to the second direction (x direction in the drawing), and the central axis of the other portion of the vibration isolator 31 is parallel to the third direction (y direction in the drawing). The first direction, the second direction, and the third direction are perpendicular to each other. It will be appreciated that the central axis of the hollow cylinder 311 coincides with the central axis of the vibration isolator 31. As can be seen from the structure of the hollow cylinder 311, the rigidity of the hollow cylinder 311 in the axial direction is greater than that in the radial direction. If the central axes of the hollow columns 311 are parallel to the same direction, the rigidity of the vibration isolation structure 30 in the radial direction of the hollow columns 311 perpendicular to the first direction is too small, so that the first support plate 10 and the second support plate 20 may slide horizontally, and the stability of the substation equipment during operation is affected. By the arrangement, the vibration isolation structure 30 can have stronger rigidity in each direction perpendicular to the first direction, and the first support plate 10 and the second support plate 20 are prevented from horizontally sliding, so that the stability of the transformer substation equipment in operation is ensured.
Further, the vibration isolator 31 having the central axis parallel to the second direction is defined as a transverse body 31a, and the vibration isolator 31 having the central axis parallel to the third direction is defined as a longitudinal body 31b. In each vibration isolation layer unit, the number of the lateral bodies 31a is equal to the number of the longitudinal bodies 31b. In particular to the embodiment shown in fig. 4, the central axis m1 of the transverse body 31a is parallel to the x-direction and the central axis m2 of the longitudinal body 31b is parallel to the y-direction. In this way, the rigidity of the vibration isolation structure 30 in the second direction is equal to that in the third direction, and the rigidity in other directions perpendicular to the first direction is stronger and similar, so that the stability of the substation equipment during operation is further ensured.
Further, in each vibration insulating layer unit, the lateral bodies 31a and the longitudinal bodies 31b are alternately arranged in the second direction and the third direction. In this way, the vibration isolation structure 30 has a uniform stiffness distribution, avoiding localized damage caused by too low localized stiffness, thereby helping to extend the useful life of the vibration isolation device 100 and maintaining its performance stable.
In particular to the embodiment shown in fig. 1 and 4, the vibration isolation structure 30 includes two vibration isolation layer units, and in each vibration isolation layer unit, the number of the transverse bodies 31a and the longitudinal bodies 31b is two. In this way, the vibration isolation apparatus 100 has a wide vertical range of motion, and can accommodate the amplification effect of the earthquake action by the building. Meanwhile, the rigidity of the vibration isolation structure 30 in each direction perpendicular to the first direction is greater than that in the first direction, so that the vibration isolation device 100 mainly deforms vertically in the working process, the first support plate 10 and the second support plate 20 are prevented from sliding horizontally, and the working stability of substation equipment is ensured.
Further, two lateral bodies 31a and two longitudinal bodies 31b form a square array, and the two lateral bodies 31a are located on one diagonal and the two longitudinal bodies 31b are located on the other diagonal. In this way, the vibration isolation structure 30 has a uniform stiffness distribution, avoiding localized damage caused by too low localized stiffness, thereby helping to extend the useful life of the vibration isolation device 100 and maintaining its performance stable.
In some embodiments, referring to fig. 2, hollow cylinder 311 includes two connections 3113 and two extensions 3114. The two connection portions 3113 are arranged at intervals along the first direction, two ends of one extension portion 3114 are connected to one side of the two connection portions 3113, and two ends of the other extension portion 3114 are connected to the other side of the two connection portions 3113. A first notch 3111 and a second notch 3112 are formed on the extension 3114. In this way, the hollow cylinder 311 can be stably coupled with other members by the coupling portion 3113, and vibration is transmitted by the extension portion 3114 to lengthen a vibration propagation path.
In some embodiments, referring to fig. 1, vibration isolation structure 30 includes a plurality of vibration isolation layer units, where vibration isolation structure 30 has vibration isolators 31 therein that are adjacent in a first direction. Two vibration insulators 31 adjacent in the first direction are connected by a connecting portion 3113. Specifically, the connection portion 3113 of the hollow cylinder 311 is provided with connection holes 3115, and bolts are inserted through the connection holes 3115 of the two connection portions 3113 to fix the two vibration insulators 31 together.
In some embodiments, one side of the vibration isolation structure 30 in the first direction is connected to the first support plate 10 by means of the connection 3113, and the other side of the vibration isolation structure 30 in the first direction is connected to the second support plate 20 by means of the connection 3113. Specifically, the connection portion 3113 at the top of the hollow cylinder 311 is fixed with the first support plate 10 by means of a bolt penetrating the connection hole 3115, and the connection portion 3113 at the bottom of the hollow cylinder 311 is fixed with the second support plate 20 by means of a bolt penetrating the connection hole 3115.
In some embodiments, with continued reference to fig. 2, the hollow cylinder 311 is configured as a hollow cylinder. In this way, on one hand, the hollow column 311 can be prevented from being partially damaged due to stress concentration, and on the other hand, the force transmission can be ensured to be continuous and smooth. Of course, in other embodiments, the hollow cylinder 311 may be configured as a hollow prism, which is not limited in this application.
In some embodiments, referring to fig. 1, the vibration isolation apparatus 100 further includes a first fastener 40 and a second fastener 50, where the member to be supported is fixed to the first support plate 10 by the first fastener 40, and the second support plate 20 is fixed to the bearing surface by the second fastener 50. So, substation equipment can stably set up on first backup pad 10, and second backup pad 20 can stably set up on the loading surface, avoids the phenomenon such as slip, toppling to appear because of self vibration or seismic action in the substation equipment working process to substation equipment's job stabilization nature has been guaranteed. Alternatively, bolts may be used for the first fastener 40 and the second fastener 50, and the number of the first fastener 40 and the second fastener 50 is 4.
In summary, the vibration isolation apparatus 100 in the embodiment of the present application includes the first support plate 10, the second support plate 20, the vibration isolation structure 30, the first fastener 40, and the second fastener 50. The first backup pad 10 bears substation equipment, and the second backup pad 20 sets up on the loading surface that substation equipment is located in the building, and vibration isolation structure 30 carries out elastic connection to first backup pad 10 and second backup pad 20, and vibration isolator 31 can radially elastic deformation in order to provide vibration isolation device 100 at the required vertical range of motion of during operation along self. In the vibration isolator 31, a tortuous vibration propagation path is formed on the hollow cylinder 311 through a first notch 3111 and a second notch 3112 provided on the hollow cylinder 311, and dissipation of energy in the vibration propagation process is achieved through the energy dissipation layer 312 coated on the surface of the hollow cylinder 311. The transformer substation equipment is fixedly arranged on the first supporting plate 10 by means of the first fastening piece 40, the second supporting plate 20 is fixedly arranged on the bearing surface by means of the second fastening piece 50, and phenomena of slipping, overturning and the like caused by vibration or earthquake action of the transformer substation equipment in the working process are avoided.
