Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a shock-resistant high and low voltage power distribution cabinet. Background Technology

[0002] High and low voltage switchgear are important electrical equipment used in power systems for power distribution, control and cable connection. They are widely used in important hubs such as substations and power supply bureaus and are an indispensable part of the power supply system.

[0003] In the existing technology, high and low voltage distribution cabinets often lack seismic resistance design. If they encounter vibrations caused by external factors (such as earthquakes) during installation and use, they are prone to damage to the internal electrical components, resulting in circuit failures and adversely affecting the power transmission for production and daily life. To address this issue, we propose a seismic-resistant high and low voltage distribution cabinet. Utility Model Content

[0005] The technical solution of this utility model is: an anti-vibration high and low voltage distribution cabinet, including a cabinet body, a cabinet door hinged to the side wall of the cabinet body, a plurality of symmetrically arranged airbags fixedly connected to the inner wall of the cabinet body, a storage battery placed on the inner bottom surface of the cabinet body, and a triggering device fixedly connected to the upper surface of the cabinet body.

[0006] Preferably, the triggering device includes a cross-shaped box, the lower surface of which is fixedly connected to the upper surface of the cabinet. A weak magnetic ball seat is provided on the inner bottom surface of the cross-shaped box, and a plurality of symmetrically arranged grooves are provided on the inner bottom surface of the cross-shaped box. A copper ball is provided on the inner wall of the weak magnetic ball seat, and a first conductive sheet is fixedly connected to the inner wall of the groove. A plurality of symmetrically arranged springs are fixedly connected to the inner top surface of the cross-shaped box, and a second conductive sheet is fixedly connected to the other end of each of the plurality of springs.

[0007] Preferably, the negative terminal of the battery is fixedly connected to the negative terminal of the adjacent airbag via a wire, the positive terminal of the battery is electrically connected to the surface of the second conductive sheet on the left side via a wire, and the plurality of second conductive sheets are electrically connected to each other via wires.

[0008] Preferably, a plurality of the first conductive sheets are fixedly connected to the positive end of the adjacent airbags by wires, and the distance between the second conductive sheet and the first conductive sheet is less than the diameter of the copper ball.

[0009] Preferably, the sidewalls of the multiple airbags penetrate the inner wall of the cabinet and extend to the outside.

[0010] Preferably, the side wall of the cabinet door is fixedly connected to a plurality of symmetrically arranged display screens, and the side wall of the cabinet door is fixedly connected to a plurality of symmetrically arranged indicator lights.

[0011] This utility model provides an improved earthquake-resistant high and low voltage distribution cabinet technology, which has the following improvements and advantages compared with the prior art:

[0012] Firstly, this utility model can detect the tilting situation when the cabinet vibrates through a triggering device on the upper surface of the cabinet. If the cabinet tilts beyond the range, it will trigger the movement of the copper ball. The copper ball will then come into contact with the first and second conductive plates, connecting the cabinet airbag to the battery circuit. The airbag will then pop out to protect the power distribution cabinet.

[0013] Secondly, this utility model installs protective airbags on all four sides of the distribution cabinet, so that when the distribution cabinet is vibrated and tilted, the airbags can be deployed in all four directions, achieving the function of shock-resistant protection for the distribution cabinet.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved earthquake-resistant high and low voltage distribution cabinet. The technical solution of this utility model is as follows:

[0022] like Figure 1 - Figure 3 As shown, an anti-vibration high and low voltage distribution cabinet includes a cabinet body 1, a cabinet door 2 hinged to the side wall of the cabinet body 1, a plurality of symmetrically arranged airbags 3 fixedly connected to the inner wall of the cabinet body 1, a storage battery 4 placed on the inner bottom surface of the cabinet body 1, and a triggering device fixedly connected to the upper surface of the cabinet body 1.

[0023] Furthermore, the triggering device includes a cross-shaped box 5, the lower surface of which is fixedly connected to the upper surface of the cabinet 1. A weak magnetic ball seat 6 is provided on the inner bottom surface of the cross-shaped box 5, and a plurality of symmetrically arranged grooves 7 are provided on the inner bottom surface of the cross-shaped box 5. A copper ball 8 is provided on the inner wall of the weak magnetic ball seat 6, and a first conductive sheet 9 is fixedly connected to the inner wall of the groove 7. A plurality of symmetrically arranged springs 10 are fixedly connected to the inner top surface of the cross-shaped box 5, and a second conductive sheet 11 is fixedly connected to the other end of each of the plurality of springs 10. The characteristic is that the copper ball 8 moves to whichever end in the cross-shaped box 5, whichever end triggers the corresponding airbag of the cabinet to work.

[0024] Furthermore, the negative terminal of the battery 4 is fixedly connected to the negative terminal of the adjacent airbag 3 via a wire, and the positive terminal of the battery 4 is electrically connected to the surface of the second conductive sheet 11 located on the left side via a wire. Multiple second conductive sheets 11 are electrically connected to each other via wires. The feature is that the circuit design is simplified and wire redundancy is reduced by electrically interconnecting the second conductive sheets 11 with wires.

[0025] Furthermore, multiple first conductive sheets 9 are fixedly connected to the positive end of adjacent airbags 3 via wires, and the distance between the second conductive sheet 11 and the first conductive sheet 9 is less than the diameter of the copper ball 8. The characteristic feature is that the copper ball 8 can smoothly roll in the cross-shaped box when it is working.

[0026] Furthermore, the side walls of multiple airbags 3 penetrate the inner wall of the cabinet 1 and extend to the outside. The characteristic is that the connection circuit of the airbags 3 can be installed inside the cabinet to protect the cables.

[0027] Furthermore, multiple symmetrically arranged display screens 12 are fixedly connected to the side wall of the cabinet door 2, and multiple symmetrically arranged indicator lights 13 are fixedly connected to the side wall of the cabinet door 2. The feature is that the working status of the power distribution cabinet can be clearly and intuitively viewed through the display screens 12 and indicator lights 13.

[0028] Working principle: When the distribution cabinet is tilted due to vibration caused by external factors, the copper ball 8 in the cross-shaped box 5 detaches from the weak magnetic ball seat 6 and is placed in the groove 7 on one side of the cross-shaped box 5, making contact with the first conductive piece 9 and the second conductive piece 11. This closes the circuit between the battery 4, the airbag 3, and the cross-shaped box 5, triggering the airbag on the corresponding side of the cabinet 1 to pop out, thereby playing the role of shockproof protection for the distribution cabinet.

[0029] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention.
