Anti-vibration power distribution cabinet

Abstract

This utility model relates to the field of power distribution cabinet technology, and in particular to an anti-vibration power distribution cabinet, including a mounting base. A lower power distribution cabinet is movably connected to the mounting base, and an upper power distribution cabinet is fixedly installed on the top of the lower power distribution cabinet. Multiple dampers are detachably installed in a square frame arrangement on the bottom inner wall of the mounting base. The top of the dampers is detachably installed to the bottom of the lower power distribution cabinet. When the lower and upper power distribution cabinets are weakened by the dampers to reduce the direct impact of ground vibration, the first and second square frame clamps and other structures reinforce the lower and upper power distribution cabinets without hindering the vibration reduction effect. This makes the power distribution cabinet significantly stronger in the event of extreme weather such as strong winds and heavy rains due to the additional structural constraints, preventing it from tipping over due to wind pressure and other factors, thus ensuring the integrity of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an anti-vibration power distribution cabinet. Background Technology

[0002] Distribution cabinets are important equipment in power systems, used for the distribution, control, protection and monitoring of electrical energy. They are widely used in industrial, commercial, civil buildings and infrastructure, and are a key link in ensuring the safe, stable and efficient operation of power supply.

[0003] When deploying distribution cabinets in complex environments such as along highways, railways, or construction sites, special attention must be paid to the impact of vibration on the equipment. Vibrations generated by passing vehicles, trains, or construction activities can be transmitted to the distribution cabinet body through the ground. This continuous mechanical vibration may not only interfere with its normal operation but also cause mechanical impact and fatigue damage to the internal circuit components. Over a long period of time, this can easily lead to faults such as poor contact and insulation failure, thereby affecting the reliability and service life of the equipment.

[0004] To address this issue, dampers are typically installed at the bottom of the distribution cabinet in engineering practice. These dampers effectively absorb and dissipate vibration energy, reducing the impact intensity of mechanical vibration on the equipment body to a safe range. This technique not only significantly reduces the direct damage of vibration to internal components but also reduces the risk of potential failures caused by mechanical fatigue.

[0005] When installing dampers at the bottom of the distribution cabinet, a mounting base is required to form a "vibration isolation" structure between the distribution cabinet and the foundation ground. In this case, the distribution cabinet and the base are only elastically connected through the damper. This design can effectively reduce the direct impact of ground vibration on the distribution cabinet through the deformation energy dissipation mechanism of the damper. However, the damper itself does not have rigid support or anti-overturning capacity. In outdoor scenarios, when the distribution cabinet encounters extreme weather such as strong winds and heavy rain, its lateral force resistance performance is significantly reduced due to the lack of additional structural constraints. It may overturn due to factors such as wind pressure, which may lead to equipment damage. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides the following technical solution: an anti-seismic distribution cabinet, including a mounting base, a lower distribution cabinet is movably connected to the mounting base, an upper distribution cabinet is fixedly installed on the top of the lower distribution cabinet, and multiple dampers are detachably installed in a square frame arrangement on the bottom inner wall of the mounting base, with the top of the dampers detachably installed to the bottom of the lower distribution cabinet.

[0007] A reinforcement mechanism for increasing the stability of the upper power distribution cabinet is fixedly installed in a square frame between the mounting base and the lower power distribution cabinet.

[0008] As an improvement to the above technical solution, the reinforcement mechanism includes a square-shaped rubber pad, a first inclined block, a second inclined block, a first square-shaped retaining plate, and a second square-shaped retaining plate. The square-shaped rubber pad is fixedly installed on the outside of the lower distribution cabinet. The outside of the square-shaped rubber pad is in contact with the inner walls of the mounting base. A first inclined groove is provided on all four sides of the outside of the mounting base. The left end of the first inclined groove passes through the square-shaped rubber pad. A second inclined groove is provided on all four sides of the outside of the lower distribution cabinet. The left end of the second inclined groove passes through the inner wall of the lower distribution cabinet. The first inclined block is movably engaged in the first inclined groove, and the second inclined block is movably engaged in the second inclined groove. The first and second inclined blocks are fixedly installed. A first limiting groove is provided on the top of the first inclined block and on the outside of the mounting base. A second limiting groove is provided on the top of the second inclined block and on the inside of the lower distribution cabinet. The first square-shaped retaining plate is movably engaged in the first limiting groove, and the second square-shaped retaining plate is movably engaged in the second limiting groove.

[0009] As an improvement to the above technical solution, the top four sides of the mounting base near the inner wall are all designed with rounded corners.

[0010] As an improvement to the above technical solution, the height of the top of the lower distribution cabinet is higher than the height of the top of the mounting base.

[0011] As an improvement to the above technical solution, L-shaped grooves are provided on the outer perimeter of the second square frame plate and near the second inclined block, and buffer rubber pads are fixedly installed on the inner wall of the L-shaped grooves.

[0012] The beneficial effects of this utility model are as follows: When the lower and upper power distribution cabinets are weakened by the damper to reduce the direct impact of ground vibration, the first and second square frame plates and other structures reinforce the lower and upper power distribution cabinets without hindering the vibration reduction effect. This makes the power distribution cabinets more resistant to lateral forces when they encounter extreme weather such as strong winds and rainstorms, due to the additional structural constraints, and they will not be overturned due to wind pressure or other factors, thus ensuring the integrity of the equipment.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an anti-seismic distribution cabinet, including a mounting base 1, a lower distribution cabinet 11 is movably connected to the mounting base 1, an upper distribution cabinet 12 is fixedly installed on the top of the lower distribution cabinet 11, and multiple dampers 13 are detachably installed in a square frame arrangement on the bottom inner wall of the mounting base 1, and the top of the dampers 13 is detachably installed to the bottom of the lower distribution cabinet 11.

[0021] A reinforcement mechanism for increasing the stability of the upper distribution cabinet 12 is fixedly installed in a square frame between the mounting base 1 and the lower distribution cabinet 11.

[0022] In this implementation scheme, when the lower-level distribution cabinet 11 and the upper-level distribution cabinet 12 are weakened by the damper 13 to reduce the direct impact of ground vibration, the reinforcement mechanism is used to reinforce the lower-level distribution cabinet 11 and the upper-level distribution cabinet 12 without hindering the vibration reduction effect. This makes the distribution cabinets significantly stronger in terms of resistance to lateral forces when they encounter extreme weather such as strong winds and rainstorms, due to the additional structural constraints, and they will not be overturned due to wind pressure or other factors.

[0023] Specifically, the reinforcement mechanism includes a square-shaped rubber pad 2, a first inclined block 23, a second inclined block 24, a first square-shaped clamping plate 27, and a second square-shaped clamping plate 28. The square-shaped rubber pad 2 is fixedly installed on the outside of the lower distribution cabinet 11. The outside of the square-shaped rubber pad 2 is in contact with the inner walls of the mounting base 1. The outer sides of the mounting base 1 are provided with first inclined grooves 21, the left end of which passes through the square-shaped rubber pad 2. The outer sides of the lower distribution cabinet 11 are provided with second inclined grooves 22, the left end of which passes through the lower distribution cabinet 11. On the inner wall of cabinet 11, the first tilting block 23 is movably engaged in the first tilting groove 21, and the second tilting block 24 is movably engaged in the second tilting groove 22. The first tilting block 23 and the second tilting block 24 are fixedly installed. The top of the first tilting block 23 and the outer side of the mounting base 1 are provided with a first limiting groove 25. The top of the second tilting block 24 and the inner side of the lower distribution cabinet 11 are provided with a second limiting groove 26. The first square frame plate 27 is movably engaged in the first limiting groove 25, and the second square frame plate 28 is movably engaged in the second limiting groove 26.

[0024] In this embodiment, by cooperating with the internal structure of the reinforcement mechanism, the overall stability of the distribution cabinet is increased without hindering the reduction of vibration on the distribution cabinet.

[0025] Specifically, the top of the mounting base 1 has rounded corners around the inner wall.

[0026] In this embodiment, it is convenient for the square rubber pad 2 to be inserted into the mounting base 1.

[0027] Specifically, the height of the top of the lower distribution cabinet 11 is higher than the height of the top of the mounting base 1.

[0028] In this embodiment, the mounting base 1 is used to prevent it from affecting the upper power distribution cabinet 12, so that the upper power distribution cabinet 12 can be opened normally.

[0029] Specifically, L-shaped grooves are provided around the outer perimeter of the second square frame plate 28 and near the second inclined block 24, and buffer rubber pads are fixedly installed on the inner wall of the L-shaped grooves.

[0030] In this embodiment, multiple buffer rubber pads are used to reduce the vibration force transmitted from the second tilting block 24.

[0031] In use, the mounting base 1 is fixed in the designated position. The damper 13 is installed on the bottom inner wall of the mounting base 1. The lower distribution cabinet 11 is then inserted into the mounting base 1, so that the perimeter of the square rubber pad 2 is in contact with the inner wall of the mounting base 1, thereby reducing the vibration force transmitted by the mounting base 1. The top of the damper 13 is then installed with the bottom of the lower distribution cabinet 11. At this time, the first inclined groove 21 and the second inclined groove 22 are aligned. Multiple first inclined blocks 23 are then inserted into the corresponding first inclined grooves 21, so that the first inclined blocks 23 drive the second inclined blocks 24 to be inserted into the corresponding second inclined grooves 22. At this time, the first square clamping plate 27 is inserted into multiple first limiting clamping slots 25, and the second square clamping plate 27 is inserted into the multiple first limiting clamping slots 25. Plate 28 is inserted into multiple second limiting slots 26, and the first tilting block 23 and the second tilting block 24 are fixed by the first square frame plate 27 and the second square frame plate 28, thereby reinforcing the lower distribution cabinet 11 and the upper distribution cabinet 12. When the lower distribution cabinet 11 and the upper distribution cabinet 12 are weakened by the damper 13, the structure of the first square frame plate 27 and the second square frame plate 28 reinforces the lower distribution cabinet 11 and the upper distribution cabinet 12 without hindering the vibration reduction effect. When the distribution cabinet encounters extreme weather such as strong winds and rain, its resistance to lateral forces is significantly enhanced due to the additional structural constraints, and it will not be overturned due to wind pressure or other factors, thus ensuring the integrity of the equipment.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
