Description

Technical Field

[0001] This invention relates to the field of power supply cabinets, and more particularly to a medium-frequency power supply cabinet module box device. Background Technology

[0002] Medium-frequency power supply cabinets, as power supply devices that convert industrial frequency AC power into specific medium-frequency AC power, are widely used in industrial fields such as metal smelting, heat treatment, and welding. With the continuous improvement of equipment integration and power density, modern medium-frequency power supply cabinets generally adopt a modular design, integrating core power conversion, control, and filtering functional units into independent module boxes, which are then installed in the overall power supply cabinet. This design facilitates production assembly, functional expansion, fault diagnosis, and maintenance / replacement.

[0003] However, in practical application and maintenance, the existing modular box installation structure has revealed the following technical defects that urgently need to be addressed: The modular enclosure has weak vibration damping and impact resistance: Medium-frequency power supply cabinets are often installed in industrial workshops, where mechanical vibration and impact are unavoidable. These vibrations may originate from the switching action of their own power devices, the operation of nearby large equipment, or vehicle transportation. In existing technologies, the modular enclosure and the cabinet are often connected rigidly or isolated by simple rubber gaskets, offering limited vibration damping. Continuous vibration can easily cause loosening or fatigue damage to precision electronic components and terminals inside the modular enclosure, reducing the reliability of electrical connections and even causing malfunctions. Furthermore, the lack of effective vibration damping allows vibration to be transmitted within the cabinet structure, potentially generating noise and affecting the lifespan of other components. While some designs consider vibration damping, their damping elements are usually independent of the installation structure, resulting in a less compact overall structure. Alternatively, the damping elements are prone to displacement or damage during frequent assembly and disassembly, making it difficult to simultaneously meet the requirements of convenient maintenance and long-term stable vibration damping.

[0004] In summary, existing modular enclosure devices for medium-frequency power supply cabinets have significant shortcomings in terms of effective vibration damping stability, which affects the long-term operational reliability and lifespan of the modules and the entire cabinet in harsh industrial environments. Therefore, there is an urgent need for an innovative modular enclosure device that can integrate an efficient and reliable vibration damping mechanism to meet the high reliability and maintainability requirements of modern industry for medium-frequency power supply equipment.

[0021] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] according to Figures 1-10 As shown, a medium-frequency power supply cabinet module box device includes a support and shock absorber and a first locking member. The support and shock absorber are on the module box 2, which facilitates the sliding installation of the module box 2 and provides shock absorption on the power supply cabinet 1. The first locking member is on the module box 2 to lock the module box 2 on the power supply cabinet 1.

[0023] The supporting vibration damping components include a first supporting vibration damping component and a second supporting vibration damping component 26. The first supporting vibration damping component and the second supporting vibration damping component 26 are symmetrically distributed on both sides of the module box 2, which facilitates the sliding installation and vibration damping of the module box 2 on the power cabinet 1. The second supporting vibration damping component 26 has the same structure as the first supporting vibration damping component.

[0024] The first support and vibration damping component includes a support mounting component and a first vibration damping component. The support mounting component is disposed on the side of the module box 2, and the first vibration damping component is disposed on the support mounting component. It is used to reduce the vibration force transmitted from the power cabinet 1 to the module box 2, so as to reduce the damage of external vibration to the electrical components inside the module box 2.

[0025] The supporting mounting component includes a mounting base 3, a convenient mounting component, and a second shock absorber. The mounting base 3 is disposed on the module box 2. The convenient mounting component facilitates the installation of the module box 2 onto the power cabinet 1. The second shock absorber provides support and vibration damping for the convenient mounting component. Furthermore, the mounting base 3 is generally rectangular in shape, and the slot of the mounting base 3 is installed on one side of the module box 2.

[0026] The convenient installation component includes a support block 4, a rotating shaft 5, and rollers 6. The support block 4 is connected to the mounting base 3 via the second and first shock absorbers. One end of the rotating shaft 5 passes through the first through hole 7 on the bottom surface of the mounting base 3 and is horizontally fixed to one side of the support block 4. The rollers 6 are rotatably mounted on the other end of the rotating shaft 5. Four sets of the convenient installation component are provided, and the four sets are distributed in a matrix at the four corners of the mounting base 3. The first through hole 7 is elongated, allowing the rotating shaft 5 to move longitudinally along the first through hole 7. When the module box 2 is installed into the power cabinet 1, the rollers 6 of the four sets of convenient installation components roll into the mounting bases 8 on both sides respectively. The mounting bases 8 are fixedly installed inside the power cabinet 1, facilitating the portable installation and disassembly of the module box 2.

[0027] The second shock absorber includes a shock absorber block 9, a first pad, and a second pad 10. One side of the shock absorber block 9 is connected to the side of the support block 4. One side of the first pad is fixedly disposed on the other side of the shock absorber block 9. One side of the second pad is fixedly disposed on the outer side of one side of the module box 2, and the other side of the second pad slides against the other side of the first pad.

[0028] Two shock absorbers 9 are provided, symmetrically distributed on both sides of the support block 4. Two first pads are provided, one on each of the two shock absorbers 9. Two second pads 10 are provided, the other being disposed on the bottom surface of the mounting base 3 groove, and the two second pads slide in contact with the two first pads. The shock absorbers 9 are made of an elastic polymer (highly elastic material) with shock absorption function.

[0029] Alternatively, the second pad is larger than the first pad, and the upper part of the second pad is thicker than the lower part of the second pad, so that the other side of the second pad is sloping. When the first pad slides upward, it will apply a compressive force to the shock absorber 9 through the second pads 10 on both sides to adjust the lateral shock absorption force of the shock absorber 9.

[0030] The second shock absorber is provided in four sets, and the four sets of the second shock absorber are provided one-to-one with the four sets of the convenient installation components, which are used to provide lateral shock absorption for the convenient installation components respectively.

[0031] The first shock absorber includes a third shock absorber, a shock absorber adjustment component, and a second locking component. The third shock absorber is disposed on the mounting base 3 and connected to the support block 4. The shock absorber adjustment component is disposed on the mounting base 3 and is drivenly connected to the third shock absorber to adjust the shock absorption of the support block 4 by the third shock absorber. The second locking component is on the mounting base 3 to lock the shock absorber adjustment component.

[0032] The third shock absorber includes a first spring 11, a second spring 12, and a first push block 13. One end of the first spring 11 is connected to the top surface of the support block 4, and the other end of the first spring 11 is connected to a groove wall on one side of the mounting base 3. One end of the second spring 12 is connected to the bottom surface of the support block 4. The first push block 13 is vertically slidably disposed within the mounting base 3, and the top surface of the first push block 13 is connected to the other end of the second spring 12. The bottom surface of the first push block 13 is inclined.

[0033] Furthermore, a first sliding groove on one side of the first push block 13 fits onto a first slider 14 on one side of the module box 2, the longitudinal direction of which is parallel to the axes of the first spring 11 and the second spring 12. A second sliding groove on the other side of the first push block 13 fits onto a second slider on the bottom surface of the mounting base 3, the longitudinal direction of which is parallel to the axes of the first spring 11 and the second spring 12. Four sets of the third shock absorber are provided, and the four sets of the third shock absorber are sequentially mounted on the four sets of convenient mounting components.

[0034] The shock-absorbing adjustment component includes a second push block 15 and a screw 16. One end of the screw 16 rotates and passes through the groove walls on both sides of the mounting base 3. The internal threaded hole on the second push block 15 fits onto the screw 16. One inclined surface of the second push block 15 slides against the inclined surface on the bottom surface of one of the first push blocks 13, and the other inclined surface slides against the inclined surface on the first push block 13 below it. Two second push blocks 15 are provided, each corresponding to one of the four sets of the third shock-absorbing components. Furthermore, the second push block 15 is generally trapezoidal in shape, and the other end face of the screw 16 is provided with an internal hexagonal hole.

[0035] When the screw 16 is rotated in the forward direction, it pushes the second push block 15 to the left through the internal threaded hole. The second push block 15, moving to the left, presses the upper first push block 13 upward, causing it to slide. The first push block 13 then compresses the second spring 12. The pressure exerted by the second spring 12 on the support block 4 improves the vertical damping efficiency. Simultaneously, the second push block 15, moving to the left, presses the lower first push block 13 downward, again improving the vertical damping efficiency through the pressure exerted by the second spring 12 on the support block 4.

[0036] The second locking component includes a locking seat 17, a locking shaft 18, a ratchet 19, a locking plate 20, and a third spring 21. The locking seat 17 is fixedly mounted on one side of the outer surface of the mounting base 3 groove. One end of the locking shaft 18 passes through a second through hole in the locking seat 17. The ratchet 19 is fixedly fitted onto the other end of the screw 16. The locking plate 20 is fixedly mounted on one end of the locking shaft 18, and the helical teeth on the inner side of the locking plate 20 can abut against the ratchet teeth on the ratchet 19 to unidirectionally limit the ratchet 19, thereby circumferentially locking the bolt. One end of the third spring 21 is connected to the top surface of the locking seat 17, and the other end of the third spring 21 is connected to the other end of the locking shaft 18. The third spring 21 is a tension spring. When the screw 16 rotates in the forward direction, the ratchet 19 will lift the locking plate 20, thereby enabling the screw 16 to rotate. When the screw 16 is subjected to a reverse rotational force, the ratchet 19 will abut against the helical teeth of the locking plate 20 to prevent the screw 16 from rotating in the reverse direction, thereby achieving locking.

[0037] The first locking component includes a locking shell 22, a locking tongue 23, a locking rod, a gear, and a locking groove 24. The locking shell 22 is fixedly mounted on the mounting base 3. The bottom end of the locking tongue 23 is horizontally and axially slidably embedded in one end tube of the locking shell 22. One end of the locking rod rotates through a third through hole on the side wall of the locking shell 22. The other end of the locking rod is provided with a handle 25. The gear is fixedly mounted on one end of the locking rod and meshes with the gear teeth on the side wall of the locking tongue 23. One end of the locking groove 24 is fixedly mounted on the mounting base 8.

[0038] Furthermore, the vertical width of the groove at the other end of the locking slot 24 is greater than the vertical width of the locking tongue 23. A rubber ring is provided on the inner ring of one end of the locking slot 24, so that the locking tongue 23 and the locking slot 24 are elastically connected through the rubber ring. When the module box 2 is pushed into the predetermined position in the power cabinet 1, the top of the locking tongue 23 is pushed by the gear and inserted into the locking slot 24 to lock the module box 2 in the predetermined position in the power cabinet 1.

[0039] Alternatively, the first locking element can be replaced with bolts and guide rail clips. Operators use special tools to tighten the bolts one by one onto the mounting base 8 to install the module box 2 inside the power cabinet 1.

[0040] As described above, the medium-frequency power supply cabinet module box device of the present invention directly integrates a first support vibration damping component and a second support vibration damping component on the module box. When the module box is installed into the power supply cabinet, the first support vibration damping component and the second support vibration damping component can work together to effectively absorb and isolate mechanical vibrations and impacts from the outside and inside of the cabinet, preventing vibration energy from being transmitted to the inside of the module box, thereby protecting the stability of the precision electronic components, power devices and electrical connections inside the box, significantly improving the long-term working reliability and service life of the module and the whole cabinet in harsh industrial vibration environments, and reducing the failure rate caused by vibration.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
