[0032] The modular switchgear assembly proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0033] Reference Figure 1-5 A modular switch cabinet assembly includes a switch cabinet body 1, with multiple partitions 11 fixedly installed on the inner side of the switch cabinet body 1, and drawer-type modules 10 slidably installed on each of the multiple partitions 11; multiple fixed frames 13 are fixedly installed on the inner side of the switch cabinet body 1, and each of the multiple fixed frames 13 is provided with a fixing mechanism on its inner side.

[0034] In this embodiment, fan vents are provided on both the upper and lower sides of the switch cabinet 1, and cooling fans 3 are fixedly installed on the inner side of both fan vents, which can enhance the heat dissipation effect of the switch cabinet 1.

[0035] In this embodiment, heat dissipation vents are provided on both the left and right sides of the switch cabinet 1. Heat sinks 2 are fixedly installed on the inner side of each heat dissipation vent. Each heat sink 2 is in contact with multiple drawer-type modules 10, which facilitates heat dissipation of the drawer-type modules 10.

[0036] In this embodiment, connecting steel plates 6 are fixedly installed at the four bottom corners of the switch cabinet 1, and buffer rubber pads 5 are fixedly installed at the bottom of the four connecting steel plates 6 to ensure the stability of the switch cabinet 1.

[0037] In this embodiment, a shock-absorbing base 4 is fixedly installed on the bottom of each of the four buffer rubber pads 5, and a shock-absorbing chamber is opened on the bottom of each of the four shock-absorbing bases 4 to facilitate the buffering of vibration.

[0038] In this embodiment, polyurethane damping plates 8 are fixedly installed on the inner sides of the four damping chambers. Each of the four polyurethane damping plates 8 has four columnar protrusions on its top. Damping springs 9 are sleeved on the outer sides of the sixteen columnar protrusions. The tops of the sixteen damping springs 9 are fixedly connected to the top inner walls of the corresponding damping chambers. Dampers 7 are fixedly installed on the top inner walls of the four damping chambers. The bottoms of the four dampers 7 are fixedly connected to the tops of the corresponding polyurethane damping plates 8, which can reduce the impact of vibration on the equipment.

[0039] In this embodiment, a fixing metal block 12 is fixedly installed on one side of each of the multiple drawer-type modules 10, and two fixing slots are opened on one side of each of the multiple fixing metal blocks 12 to facilitate fixing the drawer-type modules 10.

[0040] In this embodiment, the fixing mechanism includes a cylinder 14, a pushing metal block 15, and two linkage metal blocks 17. The cylinder 14 is fixedly installed on the inner wall of one side of the fixing frame 13. The pushing metal block 15 is fixedly installed on the piston end of the cylinder 14. A sliding opening is provided on one side of the fixing frame 13. Two linkage metal blocks 17 are slidably installed on the inner side of the sliding opening. Both linkage metal blocks 17 are in contact with the same pushing metal block 15. The pushing metal block 17 can be moved by the cylinder 14.

[0041] In this embodiment, linkage bars 16 are fixedly installed on both sides of the pushing metal block 15, and linkage grooves 18 are opened on one side of the two linkage metal blocks 17. The two linkage bars 16 are slidably installed on the inner side of the corresponding linkage grooves 18, and the corresponding linkage metal blocks 17 can be moved by the two linkage bars 16.

[0042] In this embodiment, a fixing clip 19 is fixedly installed on one side of each of the two linked metal blocks 17. The two fixing clips 19 are respectively adapted to the corresponding fixing grooves, so as to clamp and fix the metal blocks 12.

[0043] Working principle: When installing the drawer-type module 10, the operator places the drawer-type module 10 on the corresponding partition 11 and pushes it to the designated position. A fixing metal block 12 is fixedly installed on one side of the drawer-type module 10. Two fixing slots are opened on one side of the fixing metal block 12. The operator aligns the two fixing clips 19 on the fixing mechanism of the drawer-type module 10 with the corresponding fixing slots, and then slides the two fixing clips 19 into the corresponding fixing slots. Then, the cylinder 14 is activated. The piston of the cylinder 14 drives the metal block 15 to retract. The retraction of the metal block 15 moves the two linkage bars 16. Each of the two linkage metal blocks 17 has a linkage groove 18 on one side, and the two linkage grooves 18 are respectively adapted to the corresponding linkage bars 16. Therefore, when the metal block 15 is pushed to retract the two linkage bars 16, the two linkage metal blocks 17 will move with the corresponding linkage bars 16. The two linkage metal blocks 17 move closer to each other, thereby fixing and clamping the fixing metal block 12. The system secures the drawer-type module 10 to prevent it from shifting. When the drawer-type module 10 is disassembled or installed, the vibration generated by pulling it is first transmitted to the damping base 4 through the switch cabinet body 1, connecting steel plate 6, and buffer rubber pad 5. At this time, part of the vibration is absorbed by the buffer rubber pad 5. Subsequently, the damping base 4 transmits the vibration to the polyurethane damping plate 8. The polyurethane damping plate 8 absorbs part of the vibration energy through elastic compression deformation, attenuating its impact force. The damping spring 9 and the damper 7 jointly bear the vibration transmitted by the polyurethane damping plate 8. The damping spring 9 further buffers the vibration by relying on elastic expansion and contraction, converting kinetic energy into elastic potential energy for storage. The damper 7 consumes the energy of the spring's reciprocating motion through internal fluid friction, causing the vibration to decay rapidly. After multiple stages of attenuation, the energy of the vibration has been greatly reduced, thereby preventing the switch cabinet body 1 from shaking or vibrating, ensuring the stability of the switch cabinet body 1, and preventing the drawer-type module 10 from being affected by vibration and experiencing poor contact.

[0044] The technological advancements achieved by this utility model compared to the prior art are: it can clamp the drawer-type module 10, enhance the connection strength between the drawer-type module 10 and the switch cabinet 1, improve the overall shock resistance, and during equipment vibration or operation, the fixing mechanism can lock the position of the drawer-type module 10 to prevent the drawer-type module 10 from shifting and causing circuit interruption or phase-to-phase short circuit, thereby increasing the stability and safety of the equipment.

[0045] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
