Description

Technical Field

[0001] The present invention relates to an electrical cabinet, belongs to the field of electrical equipment, and in particular to an electrical cabinet with vibration reduction and noise reduction functions. Background Art

[0002] As specialized devices for housing electrical components such as circuit breakers and contactors, electrical cabinets are often constructed of metal. These enclosures offer reliable dust and moisture resistance, effectively protecting internal wiring and components and ensuring stable operation of the electrical system. However, traditional electrical cabinets generally lack shock-absorbing structures. In industrial settings, vibrations generated by machine operation are transmitted to the cabinet body through the ground or brackets in a rigid manner. Because electrical cabinets typically utilize rigid mounting methods, vibration energy directly impacts internal components, causing loose terminals and poor contact, leading to circuit failures. Long-term, continuous vibrations can also cause the cabinet structure to deform and mounting screws to loosen, reducing the protective performance of the enclosure. Dust and moisture are more likely to infiltrate the interior of the cabinet, further accelerating the aging rate and failure probability of electrical components, creating a vicious cycle that impacts equipment reliability. Therefore, electrical cabinets without shock-absorbing structures pose significant safety risks when used in long-term vibration environments.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. An electrical cabinet with shock-absorbing and noise-reducing functions according to the present invention comprises a cabinet body and a shock-absorbing device; the shock-absorbing device comprises a first fixed seat and a second fixed seat arranged horizontally opposite to each other, and the second fixed seat is provided with at least two slide grooves extending in the horizontal direction on the side of the first fixed seat facing the first fixed seat, and the slide grooves are parallel to each other. A limit column is provided in the slide groove along the horizontal direction, and the two ends of the limit column are fixedly abutted against the two end faces of the slide groove respectively, and the outer wall of the limit column is sleeved with a slider sliding along the limit column and a first spring, one end of the first spring is connected to the side of the slider, and the other end is fixedly connected to the end face of the slide groove, the slide groove and the slider clamp the first spring on the limit column, the top of the slider is rotatably connected to one end of the rotating plate, and the other end of the rotating plate is rotatably connected to the side of the first fixed seat facing the second fixed seat. During application, the second fixing seat is in direct contact with the ground or fixed to the ground by means of anchor bolts or other devices, while the first fixing seat is fixed to the bottom of the cabinet by bolts, anti-slip gaskets, and nuts to prevent the two from sliding relative to each other. If the cabinet is in a high-frequency vibration environment, epoxy structural adhesive can be injected into the gap between the cabinet and the first fixing seat to form a rigid support after curing. When external vibration is transmitted to the electrical cabinet, the vibration of the cabinet will be quickly transmitted to the first fixing seat. The vibration of the first fixing seat is transmitted to the slider of the second fixing seat through the rotating plate, causing the slider to slide horizontally along the limit column. During this process, the first spring sleeved on the limit column is compressed or stretched, and part of the vibration energy is absorbed and converted through the dynamic change of elastic potential energy. At the same time, since the top of the slider is rotatably connected to one end of the rotating plate, and the other end of the rotating plate is rotatably connected to the first fixing seat, the sliding of the slider will drive the rotating plate to swing at multiple angles. With its flexible rotating structure, the rotating plate disperses the vibration force in multiple directions, realizing secondary transmission of vibration energy, effectively attenuating the vibration amplitude, and significantly reducing the impact of vibration on the electrical cabinet and the electrical components inside the cabinet. Therefore, the present invention can operate stably in a long-term vibration environment and has low safety risks.

[0017] 2. In an electrical cabinet with a shock-absorbing and noise-reducing function according to the present invention, an L-shaped holding rack is fixedly connected to the left and right outer walls of the cabinet body, and a sound-absorbing panel is provided in the space formed by the vertical section of the holding rack and the outer wall of the cabinet body, and the lower end of the sound-absorbing panel abuts against the horizontal section of the holding rack. When in use, the sound-absorbing panel is installed on the side of the cabinet body through the limited space formed between the holding rack and the outer wall of the cabinet body, and the sound-absorbing panel absorbs and attenuates sound waves through its internal porous structure; on the one hand, the sound-absorbing panel can effectively absorb external noise, reduce the interference of external noise on the cabinet body, and reduce the transmission of external noise vibration, thereby reducing the vibration impact on the cabinet body; on the other hand, the sound-absorbing panel can also play a good role in blocking and absorbing the noise generated by the internal components of the electrical cabinet during operation, creating a low-noise operating environment for the electrical cabinet. Therefore, the present invention not only achieves dual suppression of internal and external noise by installing the sound-absorbing panel on the side of the cabinet body using the holding rack, but also can reduce the vibration impact on the cabinet body to a certain extent.

[0018] 3. In an electrical cabinet with a vibration reduction and noise reduction function of the present invention, a clamping device for fixing a sound-absorbing panel is provided on the upper side of the cabinet body, plug-in blocks are provided at both the left and right ends of the clamping device, and a slot that matches the plug-in block is provided at the upper end of the sound-absorbing panel; the clamping device includes a fixed block provided on the upper side of the cabinet body, the plug-in blocks are provided on the left and right sides of the fixed block, and the plug-in blocks are slidably connected to the fixed block, one end of the plug-in block is outside the fixed block and slidably connected to the slot, and the other end of the plug-in block is inside the fixed block; the rear side of the fixed block is slidably connected to the movable column, the tail end of the movable column is placed outside the rear side of the fixed block, and the movable column is provided at the upper end of the fixed block. The front end is inserted into the fixed block and fixedly connected to the connecting plate, the lower side of the connecting plate is fixedly connected to the upper side of the movable block, the front side of the connecting plate is penetrated by a limit rod fixedly connected to the front side of the inner surface of the fixed block, and the limit rod is inserted into the movable column and slidably connected to the movable column, the outer wall of the limit rod is sleeved with a second spring, one end of the second spring is fixedly connected to the front side of the inner surface of the fixed block, and the other end is fixedly connected to the front side of the connecting plate; the movable block is provided with an oblique groove in the area on both sides of the connecting plate, the inner surface of the oblique groove is slidably connected to the lower end of the guide column, and the upper end of the guide column is sleeved in one end of the insert block located inside the fixed block. When in use, the fixed block is fixedly connected to the upper side of the cabinet. When the sound-absorbing panel needs to be installed, the movable column is pushed forward first. The movable column will slide along the limit rod and compress the second spring at the same time. As the movable column moves, the connecting plate at its front end will also move forward, thereby driving the movable block on the lower side of the connecting plate to move forward together. The movement of the movable block causes the guide column to slide in the inclined groove. Since the outer wall of the guide column is connected to the plug-in block, the sliding of the guide column will drive the plug-in block to slide in the fixed block, prompting the plug-in block to move toward the inside of the fixed block. Then the sound-absorbing panels are placed on both sides of the cabinet by the rack and The insert is aligned with the slot in the space formed by the outer wall of the cabinet, and the movable column is released. Under the elastic force of the second spring, the insert is pushed out and inserted into the slot, thus completing the installation. Similarly, when the sound-absorbing panel needs to be removed or replaced, the movable column is pushed to disengage the insert from the slot, and the sound-absorbing panel is then removed from the storage rack. The sound-absorbing panel can be firmly fixed by the engagement of the insert and the slot through the clamping device, effectively preventing the panel from falling due to external impact, vibration, etc. At the same time, the linkage structure of the movable column, spring, and inclined slot enables convenient removal and replacement of the sound-absorbing panel. Therefore, by providing a clamping device on the upper side of the cabinet, the present invention achieves a stable installation of the sound-absorbing panel, reduces the risk of falling due to external factors, and at the same time takes into account the convenience of removal and replacement.

[0019] 4. In an electrical cabinet with a shock-absorbing and noise-reducing function according to the present invention, two support plates are provided on the top of the slider, which are opposite to each other in the horizontal direction and perpendicular to the slider. The end of the rotating plate is clamped in the middle by the two support plates and is rotatably connected to the two support plates. When in use, the two support plates and the rotating plate are provided with coaxial circular through holes. By passing the rotating shaft through the through holes of the two support plates and the rotating plate in sequence, the rotation connection of the three is achieved. When the electrical cabinet encounters a vibration shock, thanks to this connection structure between the support plate and the rotating plate, the rotating plate can swing within a larger angle range, so that the rotating plate can better drive the slider and spring connected thereto to work together, quickly converting the vibration energy into the elastic potential energy of the spring, and enhancing the effect of buffering and dispersing the vibration energy. Therefore, the rotation angle of the rotating plate in the present invention is large, so that it can better buffer and absorb the vibration energy, further improving the shock absorption performance.

[0020] 5. In an electrical cabinet with shock absorption and noise reduction functions according to the present invention, a damper is provided between the first fixed seat and the second fixed seat, one end of the damper is vertically connected to the area of ​​the second fixed seat where no slide groove is provided, and the other end is vertically connected to the first fixed seat. When in use, the damper adopts a hydraulic structure with a built-in special damping medium. When the electrical cabinet encounters vibration, the piston reciprocates in the damper cylinder, and the damping medium generates a strong damping force through the throttle hole, quickly consuming the vibration energy. The damper cooperates with shock-absorbing components such as springs, sliders, and rotating plates to effectively reduce the shaking amplitude of the cabinet and further enhance the overall shock absorption performance. Therefore, the present invention further improves the overall shock absorption performance by adding a damper between the first fixed seat and the second fixed seat and forming a multi-stage shock absorption system with components such as sliders, springs, and rotating plates.

[0031] An L-shaped holding rack 5 is fixedly connected to the left and right outer walls of the cabinet 1 , and a sound-absorbing panel 6 is provided in the space formed by the vertical section of the holding rack 5 and the outer wall of the cabinet 1 , and the lower end of the sound-absorbing panel 6 abuts against the horizontal section of the holding rack 5 .

[0032] A clamping device 7 for fixing the sound absorbing panel 6 is provided on the upper side of the cabinet 1 , and plug blocks 71 are provided at both left and right ends of the clamping device 7 . A slot 61 cooperating with the plug block 71 is provided at the upper end of the sound absorbing panel 6 .

[0033] The clamping device 7 includes a fixed block 72 arranged on the upper side of the cabinet 1, and the plug-in block 71 is arranged on the left and right sides of the fixed block 72, and the plug-in block 71 is slidably connected to the fixed block 72, one end of the plug-in block 71 is outside the fixed block 72 and slidably connected to the slot 61, and the other end of the plug-in block 71 is inside the fixed block 72.

[0034] The rear side of the fixed block 72 is slidably connected to the movable column 73, and the tail end of the movable column 73 is placed outside the rear side of the fixed block 72. The front end of the movable column is inserted into the fixed block 72 and fixedly connected to the connecting plate 74. The lower side of the connecting plate 74 is fixedly connected to the upper side of the movable block 75. The front side of the connecting plate 74 is penetrated by a limiting rod 76 fixedly connected to the front side of the inner surface of the fixed block 72, and the limiting rod 76 is inserted into the movable column 73 and slidably connected to the movable column 73. The outer wall of the limiting rod 76 is provided with a second spring 77. One end of the second spring 77 is fixedly connected to the front side of the inner surface of the fixed block 72, and the other end is fixedly connected to the front of the connecting plate 74; The movable block 75 is provided with an oblique groove 78 in the area on both sides of the connecting plate 74.

[0035] The inclined groove 78 is an obliquely arranged long strip groove body, and the inclination angle of the inclined groove 78 is 30 degrees to 60 degrees.

[0036] Two support plates 226 are provided on the top of the slider 223 , which are opposite to each other in the horizontal direction and perpendicular to the slider. The end of the rotating plate 225 is clamped between the two support plates 226 and is rotatably connected to the two support plates 226 .

[0037] A damper 8 is provided between the first fixing seat 21 and the second fixing seat 22 .

[0038] The supplementary technical features of the present invention are as follows: In this design, it is preferred that two first springs 224 are sleeved on the limiting column 222 in each slide groove 221, and the two first springs 224 are symmetrically distributed on both sides of the slider 223, firmly clamping the slider 223 on the limiting column 222 to form a bidirectional elastic buffer structure. This design can effectively enhance the buffering ability of the shock absorbing device against vibrations in different directions through the synergistic effect of the double springs, and can provide a stable rebound force during the sliding process of the slider, thereby ensuring the reliability and durability of the shock absorbing performance.

[0039] The sound-absorbing panel 6 used in this design is a widely used noise reduction material, but it has an inherent defect that its sound absorption performance will decay due to long-term use. As the use time increases, the porous structure inside the sound-absorbing panel 6 will gradually lose its sound absorption efficiency due to factors such as dust accumulation and fiber aging. If it is not replaced in time, it will be difficult to continue to effectively absorb and block the noise generated by the operation of electrical equipment. This design constructs an integrated solution for the stable installation and convenient replacement of the sound-absorbing panel 6 by providing a storage rack 5 and a clamping device 7.

[0040] In the present design, a plurality of evenly distributed small holes are preferably provided on the side of the holding rack 5. These small holes can effectively increase the contact area between the sound-absorbing panel 6 and the external noise, significantly improving the effect of the sound-absorbing panel 6 in absorbing the external noise, and avoiding the problem of poor noise reduction effect caused by placing the sound-absorbing panel 6 inside the holding rack 5 and relying only on the upper half of the holding rack 5 to absorb noise.

[0041] Example 1: See also Figure 1 — Figure 5An electrical cabinet with a shock-absorbing and noise-reducing function comprises a cabinet body 1 and a shock-absorbing device 2; the front side of the cabinet body 1 is rotatably connected to the cabinet door 3, the front side of the cabinet door 3 is fixedly connected to the handle 4, and the shock-absorbing device 2 is arranged on the lower side of the cabinet body 1; the shock-absorbing device 2 comprises a first fixing seat 21 and a second fixing seat 22 which are arranged horizontally opposite to each other, the cabinet body 1 is arranged on the first fixing seat 21, and the second fixing seat 22 is provided with at least two horizontally extending slide grooves 221 on the side facing the first fixing seat 21, and the slide grooves 221 are parallel to each other, and a limit column 2 is arranged in the horizontal direction in the slide groove 221. 22, the two ends of the limiting column 222 are fixedly abutted against the two end faces of the slide groove 221 respectively, and the outer wall of the limiting column 222 is provided with a slider 223 sliding along the limiting column and a first spring 224, one end of the first spring 224 is connected to the side of the slider 223, and the other end is fixedly connected to the end face of the slide groove 221, the slide groove 221 and the slider 223 clamp the first spring 224 on the limiting column 22, the top of the slider 223 is rotatably connected to one end of the rotating plate 225, and the other end of the rotating plate 225 is rotatably connected to the side of the first fixing seat 21 facing the second fixing seat 22.

[0042] When in use, the second fixing seat 22 is directly placed on the ground, or is fixedly connected to the ground by means of anchor bolts or the like, and the first fixing seat 21 is fixed to the bottom of the cabinet body 1 by bolts, anti-slip gaskets, and nuts; when the electrical cabinet is subjected to external vibration impact, the vibration of the cabinet body 1 will be quickly transmitted to the first fixing seat 21, and the vibration of the first fixing seat 21 will be transmitted to the slider 223 of the second fixing seat 22 through the rotating plate 225, causing the slider 223 to slide horizontally along the limit column 222. During this process, the first spring 224 sleeved on the limit column 222 is compressed or stretched, and part of the vibration energy is absorbed and converted through the dynamic change of elastic potential energy; at the same time, since the top of the slider 223 is rotatably connected to one end of the rotating plate 225, and the other end of the rotating plate 225 is rotatably connected to the first fixing seat 21, the sliding of the slider 223 will drive the rotating plate 225 to swing at multiple angles. The rotating plate 225, with its flexible rotating structure, disperses the vibration force to multiple directions, thereby realizing secondary conduction of vibration energy.

[0043] Example 2: The basic content is the same as Example 1, except that: Preferably, there are four slide grooves 221. On the side of the second fixed seat 22 facing the first fixed seat 21, the four slide grooves 221 are grouped in twos, and are distributed in groups near the two opposite side lines on the side of the second fixed seat 22 facing the first fixed seat 21, and the two slide grooves 221 in each group are collinear and parallel to the side lines; preferably, the structures of the first fixed seat 21 and the second fixed seat 22 are completely consistent, the two groups of slide grooves of the first fixed seat 21 are positioned opposite to the two groups of slide grooves 221 of the second fixed seat 22, and the other end of the rotating plate 225 connected to the top of the slider 223 in each slide groove 221 of the second fixed seat 22 is rotatably connected to the top of the slider in the other slide groove in the group opposite to the first fixed seat 21, and the rotating plates 225 connected to the two slide grooves 221 in each group are cross-structured, and the intersection of the two rotating plates 225 is a rotatable connection.

[0044] During application, when external vibration is transmitted to the electrical cabinet, the cabinet body 1 is first subjected to force and drives the first fixed seat 21 to swing up and down. Since the first fixed seat 21 and the second fixed seat 22 are linked by two sets of rotating plates 225 connected by cross rotation, the up and down displacement of the first fixed seat 21 will force the two sets of rotating plates 225 to change the crossing angle. When the first fixed seat 21 swings up or down, the intersection of the two sets of rotating plates 225 will rise or fall, driving the sliders 223 at both ends of the rotating plate 225 to slide on the limit column 222, stretching or compressing the first spring 224 sleeved on the limit column 222 and storing elastic potential energy, forming a multi-stage conduction mechanism of "cabinet body 1→first fixed seat 21→rotating plate 225→slider 223→first spring 224", which converts the vertical vibration of the cabinet body 1 into horizontal sliding of the slider 223, thereby realizing graded absorption and buffering of vibration energy.

[0045] Example 3: The basic content is the same as Example 1, except that: An L-shaped holding rack 5 is fixedly connected to the left and right outer walls of the cabinet 1. A sound-absorbing panel 6 is provided in the space formed by the vertical section of the holding rack 5 and the outer wall of the cabinet 1. The lower end of the sound-absorbing panel 6 abuts against the horizontal section of the holding rack 5.

[0046] When in use, it is preferred to open a plurality of evenly distributed small holes on the side of the holding rack 5 to increase the contact area between the sound-absorbing panel 6 and the external noise; when the electrical cabinet generates noise during operation or external noise is introduced, the sound-absorbing panel 6 can effectively absorb the sound waves by virtue of the sound-absorbing characteristics of its porous structure.

[0047] Example 4: The basic content is the same as Example 3, except that: The upper side of the cabinet 1 is provided with a clamping device 7 for fixing the sound-absorbing panel 6. The left and right ends of the clamping device 7 are provided with plug blocks 71. The upper end of the sound-absorbing panel 6 is provided with a slot 61 that cooperates with the plug block 71. The clamping device 7 includes a fixed block 72 provided on the upper side of the cabinet 1. The plug blocks 71 are provided on the left and right sides of the fixed block 72, and the plug blocks 71 are slidably connected to the fixed block 72. One end of the plug block 71 is outside the fixed block 72 and slidably connected to the slot 61, and the other end of the plug block 71 is inside the fixed block 72. The rear side of the fixed block 72 is slidably connected to the movable column 73, the tail end of the movable column 73 is placed outside the rear side of the fixed block 72, and the front end of the movable column is inserted into the fixed block 72 and connected When the locking cam 75 is in the unlocked position, the locking cam 78 is engaged with the locking cam 76, and the master lock 73 is engaged with the master lock 76. When the locking cam 76 is engaged, the master lock 73 is engaged with the master lock 76, and the master lock 73 is engaged with the master lock 76. When the locking cam 76 is engaged, the master lock 73 is engaged with the master lock 76. When the locking cam 76 is engaged, the master lock 73 is engaged with the master lock 76

[0048] When in use, the fixed block 72 is fixedly connected to the upper side of the cabinet 1. When the sound-absorbing panel 6 needs to be installed, the movable column 73 is pushed forward first. The movable column 73 will slide along the limit rod 76 and compress the second spring 77 at the same time. As the movable column 73 moves, the connecting plate 74 at its front end will also move forward, thereby driving the movable block 75 on the lower side of the connecting plate 74 to move forward together. The movement of the movable block 75 causes the guide column 79 to slide in the inclined groove 78. Since the outer wall of the guide column 79 is connected to the plug block 71, the sliding of the guide column 79 will drive The insert block 71 slides in the fixed block 72, causing the insert block 71 to move toward the inside of the fixed block 72, and then the sound-absorbing panel 6 is placed in the space formed by the receiving rack 5 and the outer wall of the cabinet 1 on both sides of the cabinet 1 and the insert block 71 is aligned with the slot 61, and then the movable column 73 is released. Under the elastic force of the second spring 77, the insert block 71 will be pushed out and inserted into the slot 61, thereby completing the installation; when the sound-absorbing panel 6 needs to be removed and replaced, the movable column 73 is pushed to disengage the insert block 71 from the slot 61, and then the sound-absorbing panel 6 can be taken out of the receiving rack 5.

[0049] Example 5: The basic content is the same as Example 1, except that: Two support plates 226 are provided on the top of the slider 223 , which are opposite to each other in the horizontal direction and perpendicular to the slider. The end of the rotating plate 225 is clamped between the two support plates 226 and is rotatably connected to the two support plates 226 .

[0050] When in use, the two support plates 226 and the rotating plate 225 are all provided with coaxial circular through holes. By passing the rotating shaft through the through holes of the two support plates 226 and the rotating plate 225 in sequence, the three are connected in a rotational connection. When the electrical cabinet encounters a vibration shock, thanks to the connection structure between the support plate 226 and the rotating plate 225, the rotating plate 225 can swing within a larger angle range, so that the rotating plate 225 can better drive the slider 223 and the first spring 224 connected thereto to work together, quickly converting the vibration energy into the elastic potential energy of the first spring 224, thereby enhancing the effect of buffering and dispersing the vibration energy.

[0051] Example 6: The basic content is the same as Example 1, except that: A damper 8 is provided between the first fixing seat 21 and the second fixing seat 22 . One end of the damper 8 is vertically connected to the area of ​​the second fixing seat 22 where the sliding groove 221 is not provided, and the other end is vertically connected to the first fixing seat 21 .

[0052] When in use, the damper 8 adopts a hydraulic structure and has a built-in special damping medium. When the electrical cabinet encounters vibration, the piston reciprocates in the cylinder of the damper 8, and the damping medium generates a strong damping force through the throttle hole, quickly consuming the vibration energy. The damper 8 cooperates with the first spring 224, the slider 223, the rotating plate 225 and other shock-absorbing components to effectively reduce the shaking amplitude of the cabinet 1 and further enhance the overall shock-absorbing performance.
