Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a vibration-resistant low-voltage switchgear, including a switchgear assembly 100, including a base 110, a vibration-resistant assembly 200, a buffer assembly 210 located on the front and back of the base 110, a limiting plate 220 fixed to the front and back of the base 110, and a hydraulic damper 230 fixed to both sides of the base 110. The buffer assembly 210 includes a base plate 211, a fixed plate 212 located on the top of the base plate 211 and fixedly connected to the base 110, damping springs 213 located on both sides of the inner cavity of the base plate 211, a movable plate 214 located on the top of the damping springs 213, a positioning bolt 215 located on the top of the movable plate 214, a positioning nut 216 located on the top of the fixed plate 212, and guide plates 217 fixed to both sides of the bottom of the fixed plate 212. The positioning nut 216 is threadedly connected to the positioning bolt 215.

[0025] like Figure 1-5As shown, when external vibrations occur, the vibration energy is first transmitted to the base 110, and then to the buffer assembly 210. At this time, the damping spring 213 exerts its elasticity and restoring force to buffer and disperse the vibration. The movable plate 214 moves up and down under the action of the damping spring 213, thereby absorbing and offsetting part of the vibration energy. At the same time, the threaded connection structure of the positioning bolt 215 and the positioning nut 216 restricts the excessive movement of the movable plate 214, ensuring that it is buffered within a certain range. The guide plate 217 guides the movement direction of the movable plate 214 to prevent it from deviating or tilting. The limiting plate 220 and the hydraulic damper 230 further enhance the vibration resistance. The limiting plate 220, by being fixed to the front and back of the base 110, restricts the displacement of the switch cabinet assembly 100 in the vibration direction. This reduces the impact of vibration on the internal structure of the switchgear. The hydraulic damper 230 dampens the vibration through its internal hydraulic oil, further consuming vibration energy and ensuring the stability and safety of the switchgear in a vibration environment. The damping spring 213, movable plate 214, positioning bolt 215 and positioning nut 216 in the buffer assembly 210 form an adjustable elastic buffer mechanism. Combined with the synergistic effect of the limit plate 220 and the hydraulic damper 230, it can effectively absorb external vibration energy and prevent the switchgear structure from loosening or components from being damaged due to vibration, thereby ensuring the stable operation of the internal electrical components. The guide plate 217 is slidably connected to the inner cavity of the base plate 211 to ensure that the buffer assembly 210 maintains a vertical direction of movement during operation, avoiding skewness or instability and improving the overall structural reliability.

[0026] Example 2

[0027] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, the switch cabinet assembly 100 also includes a mounting frame 120 fixed to the top of the base 110. The inner cavity of the mounting frame 120 is provided with a plurality of mounting chambers, and each mounting chamber is fixedly connected to a support plate.

[0029] Side plates 130 are fixedly connected to both sides of the mounting frame 120, and a top plate 140 is fixedly connected to the top of the mounting frame 120. Both the side plates 130 and the top plate 140 are fixed to the mounting frame 120 by bolts.

[0030] The surface of the mounting frame 120 and the front of each mounting chamber are bolted with a protective plate 150. Both sides of the front of the mounting frame 120 are hinged with door panels 160. The back of the mounting frame 120 is bolted with a back plate 170.

[0031] The switch cabinet assembly 100 also includes a ventilation assembly 180, which includes a fan 181 mounted on the surface of the back panel 170 and a ventilation slot 182 formed on the surface of the side panel 130.

[0032] like Figure 1-3 As shown, the mounting chambers within the mounting frame 120 are separated by support plates, ensuring that each electrical component has an independent mounting space, improving the organization and neatness of the switchgear's internal structure. The support plates within the mounting chambers are fixed to the mounting frame 120 via elastic connectors, absorbing resonance generated by the busbars. The protective plate 150 not only protects the electrical components within the mounting chambers from external environmental influences but also enhances the overall strength of the switchgear. The door panel 160 is hinged to the mounting frame 120, facilitating inspection and maintenance of the switchgear's interior. The fixed connection of the back panel 170 strengthens the structural stability of the mounting frame 120. The ventilation assembly 180 meets the heat dissipation requirements of the switchgear's interior, the fan 181 accelerates airflow within the switchgear, and the ventilation slot 182 provides an air intake and exhaust channel, effectively preventing damage to electrical components caused by excessively high temperatures within the switchgear.

[0033] Example 3

[0034] Reference Figure 4 and 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] In this embodiment, the fixed plate 212 is fixedly connected to the base 110, one end of the damping spring 213 is fixedly connected to the base plate 211, and the other end of the damping spring 213 is fixedly connected to the movable plate 214.

[0036] The end of the positioning bolt 215 away from the movable plate 214 passes through the fixed plate 212 and extends into the inner cavity of the positioning nut 216. The end of the guide plate 217 away from the fixed plate 212 extends into the inner cavity of the base plate 211 and is slidably connected to the inner cavity of the base plate 211.

[0037] like Figure 4 and 5As shown, the stable connection between the fixed plate 212 and the base 110 ensures that the buffer assembly 210 can stably bear and disperse vibration energy. The two ends of the damping spring 213 are fixedly connected to the base plate 211 and the movable plate 214 respectively, so that the damping spring 213 can effectively exert its elasticity and restoring force when subjected to vibration to buffer the vibration. At the same time, the tight fit of the positioning bolt 215 and the positioning nut 216 not only enhances the overall structural strength of the buffer assembly 210, but also ensures the stability of the movable plate 214 during the buffering process. The sliding connection between the guide plate 217 and the inner cavity of the base plate 211 improves the reliability and durability of the buffer assembly 210 during operation, ensuring that it can still maintain a good buffering effect under long-term vibration environment.

[0038] In use, when external vibrations occur, the vibration energy is first transmitted to the base 110, and then to the buffer assembly 210. At this time, the damping spring 213 exerts its elasticity and restoring force to buffer and disperse the vibration. The movable plate 214 moves up and down under the action of the damping spring 213, thereby absorbing and offsetting part of the vibration energy. At the same time, the threaded connection structure of the positioning bolt 215 and the positioning nut 216 restricts the excessive movement of the movable plate 214, ensuring that it buffers within a certain range. The guide plate 217 guides the movement direction of the movable plate 214 to prevent it from deviating or tilting. The limiting plate 220 and the hydraulic damper 230 further enhance the vibration resistance effect. Position plate 220, fixed to the front and back of base 110, restricts the displacement of switch cabinet assembly 100 in the vibration direction, thereby reducing the impact of vibration on the internal structure of switch cabinet. Hydraulic damper 230 dampens vibration through its internal hydraulic oil, further consuming vibration energy. The damping spring 213, movable plate 214, positioning bolt 215 and positioning nut 216 in buffer assembly 210 form an adjustable elastic buffer mechanism. Combined with the synergistic effect of limit plate 220 and hydraulic damper 230, it can effectively absorb external vibration energy, prevent the switch cabinet structure from loosening or components from being damaged due to vibration, thereby ensuring the stable operation of internal electrical components.

[0039] Meanwhile, the mounting chambers within the mounting frame 120 are separated by support plates, ensuring that each electrical component has an independent mounting space, which improves the organization and neatness of the internal structure of the switchgear. The protective plate 150 not only protects the electrical components in the mounting chamber from the influence of the external environment, but also enhances the overall strength of the switchgear. The ventilation component 180 meets the heat dissipation requirements inside the switchgear, effectively preventing damage to electrical components inside the switchgear due to excessive temperature.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field.

Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention.
