Description

Technical Field

[0001] This utility model relates to the field of low-voltage power distribution technology, and in particular to a vibration and noise reduction device for low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear, as a key piece of equipment in low-voltage power distribution systems, is used for centralized control, protection, and distribution of low-voltage electrical energy. It assembles circuit breakers, contactors, relays, and various low-voltage electrical components in a closed or semi-closed metal cabinet according to a specific electrical circuit scheme. In various industrial sites, commercial buildings, and residential areas, low-voltage switchgear plays a crucial role in rationally distributing the low-voltage electrical energy output from transformers to different electrical equipment or areas. It realizes the functions of circuit start-up and shutdown control, fault protection, and operating parameter monitoring, ensuring the safe, stable, and efficient operation of the power system and providing reliable power support for the normal operation of various electrical equipment.

[0003] When using existing switchgear, if the internal layout of the switchgear needs to be changed or new functional modules are added, the partitions will block maintenance personnel from fully accessing the internal components. If deep components need to be repaired, multiple other parts need to be removed, which is a cumbersome process and can easily damage surrounding components. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a shock-absorbing and noise-reducing device for low-voltage switchgear, which aims to improve the problem of difficulty in maintaining internal components in existing switchgear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shockproof and noise-reducing device for a low-voltage switchgear, comprising a housing, wherein multiple second sliding grooves are provided on both the left and right sides of the inner wall of the housing, and a movable plate is slidably connected between two adjacent second sliding grooves, and a sliding block is slidably connected to the inner wall of each of the multiple movable plates, a first sliding groove is provided on the top of each of the multiple sliding blocks, and a locking element is slidably connected in each of the multiple first sliding grooves, and two tension springs are fixedly connected to the rear side of each of the multiple sliding blocks, and the rear ends of each of the multiple tension springs are fixedly connected to the inner wall of an adjacent movable plate, and a base is provided at the bottom of the housing, and buffer components are provided at the four corners of the top of the base, the buffer components being used to buffer collisions.

[0006] Preferably, the buffer assembly includes a fixing member, which is rotatably connected to the base. A movable ring is threaded onto the surface of the fixing member. A spring is provided at the top of the movable ring. A connecting member is fixedly connected to the top of the spring. A damping rod is fixedly connected to the inner diameter of the fixing member. The top of the damping rod is fixedly connected to the connecting member. The top of the connecting member is rotatably connected to the outer shell.

[0007] Preferably, a connecting block is fixedly connected to the bottom of the outer shell, and the bottom of the connecting block is fixedly connected to the base.

[0008] Preferably, two hinges are fixedly connected to the front side of the outer casing, and a cover plate is fixedly connected between the two hinges.

[0009] Preferably, multiple limiting grooves are provided on both the left and right sides of the inner wall of the outer shell.

[0010] Preferably, a plurality of sound-insulating cotton is fixedly connected to the inner wall of the outer shell, and a sound-absorbing felt is fixedly connected to the front side of the outer shell.

[0011] Preferably, the plurality of locking elements extend through and to the outside of the adjacent movable plate on the side away from the sliding block, and the plurality of locking elements are slidably connected to the adjacent movable plate.

[0012] Preferably, each of the sliding blocks has a pull plate fixedly connected to its bottom, and the bottom of each pull plate extends through and to the bottom of the adjacent movable plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the sliding block is moved by pulling the bottom plate. When the sliding block moves, the tension spring is stretched. At this time, the locking parts on both sides slide in the first sliding groove. At this time, the locking parts are disengaged from the limiting groove. Pulling the moving plate can pull the moving plate out. Maintenance personnel can directly access the inside of the equipment without complicated operations or the use of a lot of tools, which greatly reduces the difficulty of maintenance, saves maintenance time, and improves maintenance efficiency.

[0015] 2. In this utility model, by rotating the movable ring, the movable ring moves on the fixed part. The movable ring compresses the spring, causing the spring to press against the top connecting part. At the same time, the damping rod buffers the connecting part. This allows the spring to absorb some of the vibration energy when encountering vibration or external impact during equipment operation, and the damping rod to further dissipate the vibration, reducing the displacement and swaying of the connecting part caused by vibration, improving the stability of the entire structure, and protecting the connected equipment or components from vibration damage. By rotating the movable ring to move it on the fixed part, the degree of compression on the spring can be precisely adjusted, thereby controlling the spring's support force on the top connecting part.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a shock-absorbing and noise-reducing device for a low-voltage switchgear, comprising a housing 1. Multiple second sliding grooves 13 are provided on both the left and right sides of the inner wall of the housing 1. A movable plate 5 is slidably connected between two adjacent second sliding grooves 13. Sliding blocks 9 are slidably connected to the inner walls of the multiple movable plates 5. A first sliding groove 10 is provided on the top of each of the multiple sliding blocks 9. A locking element 11 is slidably connected within each of the multiple first sliding grooves 10. Two tension springs 12 are fixedly connected to the rear sides of each of the multiple sliding blocks 9. The rear ends of each tension spring 12 are fixedly connected to the inner walls of adjacent movable plates 5. A base 4 is provided at the bottom of the housing 1. Buffer components are provided at the four corners of the top of the base 4 for buffering collisions.

[0026] Specifically, if the user wants to perform maintenance on the inside of the low-voltage switchgear, they only need to pull the pull plate 8 at the bottom of the outer casing 1. The pull plate 8 drives the sliding block 9, which is slidably connected to the inner wall of the movable plate 5, to move. When the sliding block 9 moves, it stretches the tension spring 12 fixedly connected to its rear side. At the same time, the locking piece 11 in the first slide groove 10 at the top of the sliding block 9 slides in the groove and disengages from the limiting groove 14 on the inner wall of the movable plate 5. At this time, the movable plate 5 can be easily pulled out from the second slide groove 13 opened on the left and right sides of the inner wall of the outer casing 1. Thus, without complicated operations and a large number of tools, the user can directly contact the inside of the equipment for maintenance. After maintenance, push the movable plate 5 backward until the locking piece 11 is inserted into the limiting groove 14 to quickly fix the movable plate 5.

[0027] Reference Figure 5 and Figure 6 The buffer assembly includes a fixing member 16, which is rotatably connected to the base 4. A movable ring 17 is threadedly connected to the surface of the fixing member 16. A spring 18 is provided at the top of the movable ring 17. A connector 20 is fixedly connected to the top of the spring 18. A damping rod 19 is fixedly connected to the inner diameter of the fixing member 16. The top of the damping rod 19 is fixedly connected to the connector 20. The top of the connector 20 is rotatably connected to the outer shell 1.

[0028] Specifically, when the user needs to adjust the support force on the top connector 20, the moving ring 17 is rotated. The moving ring 17 moves on the fixed part 16 to compress the spring 18, thereby precisely adjusting the support force of the spring 18 on the top connector 20 and controlling the support state of the connector 20. During the operation of the equipment, if vibration or external impact is encountered, the damping rod 19, which is fixedly connected to the inner diameter of the fixed part 16 and fixedly connected to the connector 20 at its top, will buffer the connector 20. At the same time, the spring 18 absorbs part of the vibration energy, and the damping rod 19 further consumes the vibration, reducing the displacement and shaking of the connector 20 caused by vibration, improving the overall structural stability, and protecting the outer shell 1 connected to the connector 20.

[0029] Reference Figure 5 A connecting block 15 is fixedly connected to the bottom of the outer shell 1, and the bottom of the connecting block 15 is fixedly connected to the base 4.

[0030] Specifically, the connecting block 15 is made of high-strength aluminum alloy, which can withstand greater pressure, ensuring a stable connection between the outer shell 1 and the base 4. It resists various stresses during the operation of the switch cabinet and prevents damage to the connection parts. The aluminum alloy has both good strength and light weight, which ensures the reliability of the connection and reduces the overall weight.

[0031] Reference Figure 1 Two hinges 3 are fixedly connected to the front side of the outer casing 1, and a cover plate 2 is fixedly connected between the two hinges 3.

[0032] Specifically, the cover plate 2 can rotate around the hinge 3, making it easy to open and close the outer casing 1. When it is necessary to perform operations inside the switch cabinet, such as inspection, maintenance, or checking the status of components, the cover plate 2 can be opened. After the operation is completed, the cover plate 2 can be closed to protect the internal components, prevent dust and foreign objects from entering, and at the same time protect personnel safety to a certain extent.

[0033] Reference Figure 4 Multiple limiting grooves 14 are provided on both the left and right sides of the inner wall of the outer shell 1.

[0034] Specifically, when the locking member 11 is engaged in the limiting groove 14, it can restrict the free sliding of the moving plate 5 in the second slide groove 13, so that the moving plate 5 remains stable under normal working conditions.

[0035] Reference Figure 2 Multiple sound-insulating cotton 6 are fixedly connected to the inner wall of the outer shell 1, and a sound-absorbing felt 7 is fixedly connected to the front side of the outer shell 1.

[0036] Specifically, multiple sound-absorbing cotton 6 are fixedly connected to the inner wall of the outer shell 1, which can effectively absorb the noise generated inside the switch cabinet, dissipate the noise inside the cabinet, and reduce the noise transmission to the outside. Sound-absorbing felt 7 is fixedly connected to the front of the outer shell 1, which can further absorb the noise transmitted from the front of the switch cabinet. The dual settings enhance the sound insulation and noise reduction effect of the entire switch cabinet, reduce noise interference to the surrounding environment, create a quieter working environment for operators, and avoid noise affecting other nearby equipment.

[0037] Reference Figure 3 Multiple locking elements 11 extend through and to the outside of the adjacent movable plate 5 on the side away from the sliding block 9, and multiple locking elements 11 are slidably connected to the adjacent movable plate 5.

[0038] Specifically, the locking element 11 can slide flexibly on the movable plate 5, which is convenient to move the sliding block 9 to drive the locking element 11 to engage or disengage with the limiting groove 14. During normal operation, the locking element 11 slides into the limiting groove 14 to stabilize the position of the movable plate 5 and ensure the stability of the internal structure. When the movable plate 5 needs to be pulled out for maintenance, the locking element 11 can slide out smoothly from the limiting groove 14, providing conditions for the removal of the movable plate 5.

[0039] Reference Figure 2 and Figure 3 Each of the sliding blocks 9 has a pull plate 8 fixedly connected to its bottom, and the bottom of each pull plate 8 extends through and to the bottom of the adjacent movable plate 5.

[0040] Specifically, users can easily move the sliding block 9 by directly pulling the pull plate 8, thereby controlling the position of the locking part 11, allowing the locking part 11 to disengage from the limit groove 14, and conveniently and quickly pulling out the moving plate 5, greatly simplifying the operation process of the moving plate 5.

[0041] Working principle: When the user needs to perform internal maintenance on the low-voltage switchgear, pull the bottom pull plate 8 of the outer shell 1. The pull plate 8 drives the sliding block 9 on the inner wall of the movable plate 5 to move. The sliding block 9 stretches the rear tension spring 12. At the same time, the locking piece 11 in the first slide groove 10 at the top slides away from the limiting groove 14 on the inner wall of the movable plate 5. The movable plate 5 can then be pulled out from the second slide groove 13 on the inner wall of the outer shell 1. Internal maintenance can be performed without complicated operations and a large number of tools. After maintenance, push the movable plate 5 to make the locking piece 11 engage with the limiting groove 14 for fixation.

[0042] Rotating the moving ring 17 can move the compression spring 18 on the fixed part 16 to adjust the support force on the top connector 20. When encountering vibration or external impact during operation, the damping rod 19 buffers the connector 20, the spring 18 absorbs part of the vibration energy, and the damping rod 19 further consumes the vibration to ensure structural stability. The sound insulation cotton 6 on the inner wall of the outer shell 1 and the sound-absorbing felt 7 on the front side reduce noise.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
