Abstract
Description
Technical Field
[0001] This invention relates to the field of switchgear technology, and more specifically, to a vibration-isolated switchgear. Background Technology
[0002] Switchgear is a crucial electrical device in power systems, primarily used in power generation, transmission, distribution, and energy conversion. It performs opening and closing operations on circuits and provides control and protection functions. Switchgear contains numerous precision electrical components, which are frequently exposed to various vibration sources, such as machine operation in industrial plants, structural vibrations in high-rise buildings, and seismic waves in earthquake-prone areas. If these vibrations are not isolated, they will be transmitted to the switchgear, causing components to loosen, wear more rapidly, develop poor contacts, or even become damaged. This affects the stable operation of the switchgear, increases the probability of malfunctions, threatens power supply safety and reliability, and shortens the equipment's lifespan.
[0003] Currently, most existing switchgear typically uses traditional rigid support structures, such as simple metal brackets or feet. These support structures directly connect the cabinet to the ground or mounting foundation, with almost no vibration isolation measures. When external vibrations occur, the vibrations are transmitted to the inside of the switchgear through the support structure, causing vibration and shaking of internal components. Even if some switchgear uses rubber pads as support and buffer, the vibration isolation effect they provide is limited. Rubber pads are prone to aging and loss of elasticity, and their vibration damping performance drops significantly after long-term use.
[0004] Therefore, we propose a vibration-isolated switchgear. Summary of the Invention
[0005] This invention provides a vibration-isolated switchgear, which, by incorporating a damping device and a stabilizing component formed by combining damping components and elastic elements at the bottom of the base, along with a bottom support, effectively isolates the switchgear from vibrations generated by various vibration sources such as the operation of machinery in industrial plants and the slight movement of high-rise building structures, thereby solving the problems mentioned in the background art. Existing switchgear vibration isolation measures are insufficient. Traditional rigid supports or simple rubber pads cannot effectively cope with complex vibration environments, causing internal components to loosen and wear due to vibration, affecting equipment stability, lifespan, and power supply safety.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A vibration-isolated switch cabinet includes a base, a cabinet body is fixedly connected to the top of the base, a plurality of damping components are fixedly connected to the bottom of the base, a plurality of stabilizing components are provided at the bottom of the damping components, and a support is fixedly connected between the bottoms of the plurality of stabilizing components. An elastic element is provided between the damping component and the base, and the damping component and the elastic element are combined to form a damping device.
[0007] In the above scheme, the damping component includes a cylinder, a piston is provided inside the cylinder, a rod is provided at the end of the piston, the top of the rod is fixedly connected to the base, and an air pipe is provided on the outer wall of the cylinder, the air pipe being a U-shaped pipe connecting the upper and lower chambers of the cylinder.
[0008] Preferably, the outer edge of the piston is arc-shaped, and a gap is left between the piston and the air pipe port.
[0009] Based on this, rotating rods are provided on all four outer walls of the cylinder body, and the stabilizing component is rotatably connected to the outer wall of the rotating rods.
[0010] Preferably, the stabilizing component includes two support plates, which are fixedly connected to the top of the support. A support rod is coaxially connected between the two support plates and the outer wall of the rotating rod, and the ends of the two support rods are coaxially connected through a rotating shaft.
[0011] In this technical solution, the bottom of the base has a concave structure, and the damping component is supported inside the groove on the bottom surface of the base.
[0012] Preferably, a support member is fixedly connected between the bottom of the base and the support. The support member has an overall square corrugated tube structure and is hollow. Multiple damping components, elastic components and stabilizing components are located inside the support member. The support member is made of rubber.
[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In a vibration isolation switchgear, a damping device is formed by combining multiple damping components and elastic elements at the bottom of the base, and a stabilizing component is set at the bottom of the damping components and connected to the support. At the same time, a synergistic vibration isolation system is constructed by using a support component made of rubber with a square corrugated tube structure between the base and the support. When external vibration sources such as the operation of machinery in industrial plants or the slight movement of structures in high-rise buildings generate vibration, the vibration is transmitted to the switch cabinet. First, the support components provide initial buffering and shock absorption. Then, the elastic components in the damping device play an elastic deformation role to buffer the vibration energy. The piston, cylinder, air pipe and other structures in the damping assembly cooperate to further consume the vibration energy through the movement of the piston in the cylinder and its cooperation with the air pipe.
[0014] 2. In a vibration-isolated switchgear, the stabilizing component ensures the stability of the overall structure during vibration by rotating it with the cylinder rod and linking it with its own support plate, support rod and other structures. This effectively isolates the vibration from being transmitted to the inside of the switchgear, overcoming the problem of insufficient vibration isolation measures in existing switchgear.
[0015] 3. In a vibration-isolated switchgear, vibration is effectively isolated through the coordinated linkage of the above-mentioned components. This prevents the numerous precision electrical components inside the switchgear from becoming loose, experiencing increased wear, poor contact, or even being damaged due to vibration. This ensures that the components can work in a relatively stable environment, thereby ensuring the stable operation of the switchgear, reducing the probability of failure, extending the service life of the equipment, and changing the situation in the prior art where the equipment is easily affected due to poor vibration isolation.
[0016] 4. In a vibration-isolated switchgear, a square corrugated rubber support is installed between the bottom of the base and the support. The support is hollow and encloses the cylinder, elastic component, and stabilizing component. The elasticity of the rubber material is used to further absorb vibration energy, while forming physical protection for the internal vibration isolation components, isolating them from external dust and liquid corrosion, improving the applicability of the equipment in harsh environments, and improving the shortcomings of the vibration isolation components in the prior art that are susceptible to environmental influences.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example
[0020] Currently, existing vibration isolation measures for switchgear are insufficient. Traditional rigid supports or simple rubber pads cannot effectively cope with complex vibration environments, leading to internal components being prone to loosening and wear due to vibration, affecting equipment stability, lifespan, and power supply safety. Please refer to [link / reference needed]. Figures 1-4 The vibration isolation switch cabinet shown includes a base 11, characterized in that: a cabinet body 1 is fixedly connected to the top of the base 11, a plurality of damping components 14 are fixedly connected to the bottom of the base 11, a plurality of stabilizing components 16 are provided at the bottom of the damping components 14, and a support 12 is fixedly connected between the bottoms of the plurality of stabilizing components 16. An elastic element 15 is provided between the damping component 14 and the base 11, and the damping component 14 and the elastic element 15 are combined to form a damping device.
[0021] When implementing, refer to Figure 5 and Figure 6 As shown, the damping assembly 14 includes a cylinder 140, a piston 142 is provided inside the cylinder 140, a rod 141 is provided at the end of the piston 142, the top of the rod 141 is fixedly connected to the base 11, and an air pipe 143 is provided on the outer wall of the cylinder 140. The air pipe 143 is a U-shaped pipe connecting the upper and lower chambers of the cylinder 140.
[0022] When there is vibration from external sources such as the operation of machinery in an industrial plant, the vibration is transmitted to the switch cabinet, and the base 11 will move up and down or in other directions accordingly; since the rod 141 is connected to the base 11, the piston 142 will reciprocate accordingly in the cylinder 140. When piston 142 moves upward within cylinder 140, it compresses the gas in the upper part of cylinder 140. This compressed gas then flows through air pipe 143 to the lower part of cylinder 140. Due to the narrow inner wall of air pipe 143, the gas flow generates some resistance, thus consuming some vibration energy. Similarly, when piston 142 moves downward, the gas in the lower part of cylinder 140 is compressed and flows through air pipe 143 to the upper part of cylinder 140. Energy is also consumed during the gas flow due to the flow-limiting effect of air pipe 143. Through the reciprocating motion of piston 142 in cylinder 140 and the directional flow and obstruction of gas in air pipe 143, the vibration energy transmitted from the outside is gradually consumed. This, together with other components such as elastic element 15 and stabilizing component 16 in the entire vibration isolation switchgear, effectively isolates the transmission of vibration to the inside of the switchgear, avoids loosening and wear of internal components due to vibration, and ensures the stability, service life and power supply safety of the equipment.
[0023] In order to optimize the gas flow characteristics within the damping assembly 14, so that it can form a stable airflow buffering effect during vibration, and avoid the damping effect failure or sudden airflow due to the piston 142 completely blocking the air pipe 143 port, thereby improving the adaptability of the damping assembly 14 to vibrations of different frequencies and the energy consumption efficiency; wherein, the outer edge of the piston 142 is arc-shaped, and a gap is left between the piston 142 and the air pipe 143 port; The arc-shaped structure on the outside of piston 142 reduces gas flow resistance and turbulence, allowing gas to pass more smoothly through the port of air pipe 143 during the reciprocating motion of piston 142. When piston 142 moves upward, the gas compressed in the upper part of cylinder 140 is guided by the arc-shaped edge of piston 142, flowing smoothly into air pipe 143 and towards the lower part of cylinder 140; similarly, when piston 142 moves downward, the gas in the lower part flows into air pipe 143 and towards the upper part of cylinder 140 through the arc-shaped edge. This guiding effect avoids airflow impact and uneven energy loss that may be caused by right-angled edges, making the gas flow more uniform and the damping effect more stable. The gap between piston 142 and the port of air pipe 143 ensures the continuity of gas flow, meaning that piston 142 does not completely block the port of air pipe 143. Even if piston 142 moves to a position close to the port of air pipe 143, the gap can still maintain a certain air flow, avoiding the instantaneous disappearance of damping force due to piston 142 completely blocking the port.
[0024] Based on this, refer to Figure 7 As shown, the cylinder body 140 has rotating rods on all four outer walls, and the stabilizing assembly 16 is rotatably connected to the outer wall of the rotating rods.
[0025] The stabilizing assembly 16 includes two support plates 160, which are fixedly connected to the top of the support 12. Support rods 161 are coaxially connected between the two support plates 160 and the outer wall of the rotating rod. The ends of the two support rods 161 are coaxially connected through a rotating shaft.
[0026] When vibration is transmitted and causes vertical displacement of the cylinder 140, the stabilizing component 16 can rotate around the shaft due to the connection between the rotating rod, support rod 161, and rotating shaft. This allows the cylinder 140 to move smoothly up and down vertically, ensuring that the elastic element 15 can properly perform its vibration damping function. In the horizontal direction, this structure effectively limits the cylinder 140, restricting its lateral displacement or swaying caused by vibration. It prevents lateral forces on the elastic element 15 caused by irregular movement of the cylinder 140, avoiding bending, deformation, or even failure of the spring in the elastic element 15 due to lateral force. This ensures that the entire vibration isolation system can stably and continuously isolate the cabinet 1 from broadband vibration, maintain the stability of the cabinet 1 in a vibration environment, and protect the internal electrical components from vibration.
[0027] Additionally, see Figure 3 As shown, the bottom of the base 11 has a concave structure, and the damping component 14 is supported inside the groove on the bottom surface of the base 11.
[0028] The groove structure provides a certain degree of physical protection for the damping component 14, reducing its exposed area to the external environment and lowering the risk of impact and scratches from external objects. This helps maintain the appearance integrity and normal performance of the internal structure of the damping component 14, extending its service life to ensure the continuity of the vibration isolation function. Furthermore, without increasing the overall floor space of the switch cabinet, the space under the base 11 is used to install the damping component 14, while creating reasonable spatial layout conditions for the arrangement of other vibration isolation components such as the elastic element 15 and the stabilizing component 16. This allows the entire vibration isolation system to be compactly and orderly integrated at the bottom of the cabinet 1, thereby improving space utilization.
[0029] Among them, a support member 13 is fixedly connected between the bottom of the base 11 and the support 12. The support member 13 has a square corrugated tube structure and is hollow. Multiple damping components 14, elastic components 15 and stabilizing components 16 are located inside the support member 13. The support member 13 is made of rubber.
[0030] When external vibrations are transmitted, firstly, the elasticity of the rubber itself provides initial buffering, absorbing some vibration energy and reducing the intensity of the vibration transmitted to cabinet 1. Secondly, the corrugated pipe structure can undergo corresponding expansion and contraction deformation under vibration, using this deformation to further dissipate vibration energy. Furthermore, during the expansion and contraction process, internal mechanisms such as friction between rubber molecules also convert some vibration energy into heat energy for dissipation. Thirdly, the support component 13, as an integral protective structure, protects the key internal vibration isolation components, isolating them from external dust, moisture, and other impurities, preventing these impurities from affecting the normal operation of the vibration isolation components, ensuring the stable operation of the entire vibration isolation system. Finally, in conjunction with the elastic component 15, damping component 14, and stabilizing component 16, it more effectively achieves broadband vibration isolation of cabinet 1, ensuring that the electrical components inside the switchgear can still operate normally under complex vibration environments, maintaining equipment stability, extending service life, and ensuring power supply safety.
