Problems solved by technology

[0004] However, the direct damping method of the elastic element usually used in the prior art has two disadvantages: first, the stability is poor, the spring reduces the impact by reducing the vibration frequency and expanding the amplitude, and the stability of this linear damping method is relatively poor , although it can play a shock-absorbing effect, the effect is limited by the spring structure and is not ideal. The second is that the energy dissipation problem is less considered. The impact energy brought by vibration is fixed, and the energy concentration is relieved by the spring Although the release effect is a conventional method, it is far less effective than dissipating the vibration energy as soon as possible

Embodiment 1

[0041] The ratio of the width and thickness of the shock absorbing ring 11 is between 0.5-2 and the thickness of the shock absorbing ring 11 is greater than 5 millimeters. At this time, the rigidity of the shock absorbing ring 11 is relatively large, and the longitudinal flexible hinge 15 and the horizontal hinge on the shock absorbing ring 11 The flexible hinge 16 plays a role of rotation, and the four parts connected by the vertical flexible hinge 15 and the horizontal flexible hinge 16 of the shock absorbing ring 11 play the role of a rigid link frame. Enhance the stability of the overall structure.

Embodiment 2

[0043] The ratio of the width and thickness of the shock absorbing ring 11 is between 0.5-2 and the thickness of the shock absorbing ring 11 is at 3-5 millimeters. At this moment, the rigidity of the shock absorbing ring 11 is less, and the longitudinal flexible hinge 15 on the shock absorbing ring 11 And the horizontal flexible hinge 16 plays a role of rotation, the main body of the shock absorbing ring 11 plays a part of the elastic effect, and the four parts connected by the vertical flexible hinge 15 and the horizontal flexible hinge 16 of the shock absorbing ring 11 play the role of an elastic link frame, reducing The installation quantity of shock ring 11 is not less than 4, to enhance the stability of the overall structure.

Embodiment 3

[0045] The ratio of the width to the thickness of the shock absorbing ring 11 is greater than 3. At this time, the stiffness of the shock absorbing ring 11 is small, and the vertical flexible hinge 15 and the horizontal flexible hinge 16 on the shock absorbing ring 11 play a role of rotation, and the main body of the shock absorbing ring 11 plays a role of rotation. To achieve a part of the elastic effect, the four parts connected by the vertical flexible hinge 15 and the horizontal flexible hinge 16 of the shock absorbing ring 11 play the role of an elastic link frame and have an orientation function. The number of shock absorbing rings 11 installed is not less than 2, To enhance the stability of the overall structure.

Abstract

The invention discloses a power cabinet with a nonlinear damping platform, comprising a power cabinet body composed of hot-dip galvanized lace angle iron and a sheet metal skin, the bottom of the power cabinet body is embedded with an upper opening cavity structure The base of the power cabinet is equipped with an organ-shaped damping unit at the center of the bottom of the base. The damping unit can efficiently consume vibration energy in multiple directions. Multiple nonlinear damping units are set around the bottom of the base of the power cabinet. , the nonlinear damping unit uses flexible hinges to improve sensitivity and stability. The four parts of the damping ring in the nonlinear damping unit are connected by longitudinal flexible hinges and transverse flexible hinges to play the role of the link frame. The link frame structure is folded The non-linear stiffness vibration isolation effect is generated between the shrinkage and elastic elements. The power cabinet base, the damping shock-absorbing unit and multiple nonlinear shock-absorbing units are combined into a nonlinear shock-absorbing platform, which is designed through a nonlinear structure. It has good bearing capacity and stability.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a power cabinet with a nonlinear damping platform. Background technique [0002] The power cabinet is a commonly used power infrastructure. It is equipped with a large number of power components. The power cabinet has the characteristics of long-term continuous operation. The power cabinet is generally placed in the open air, so the external weather conditions may affect the environment inside the power cabinet. Since the electrical components inside the power cabinet are operated continuously for a long time, the electrical devices in the cabinet will generate heat during operation, and the heat will affect the rubber insulating material in the power cabinet, resulting in accelerated aging and reduced insulation performance. Severe aging may lead to short circuit of internal electrical components, resulting in accidents, and the electrical components placed in the cabinet...
