Description

Technical Field

[0001] The present invention relates to the technical field of maintenance of dual - power supply, and particularly to a dual - power supply system for a thermal control power cabinet. Background Art

[0002] Currently, a dual - power switching device is set in the thermal control power cabinet of the existing desulfurization, denitrification and dust removal projects: one is a UPS power supply, and the other is a mains power supply. Since the commonly selected dual - power switching device cannot reach the millisecond level; when one power supply fails and automatically switches to the other power supply, it will cause a temporary power outage, resulting in the restart of the DCS device, and the consequences are very serious.

[0003] By canceling the dual - power switching device in the thermal control power cabinet and directly taking a UPS power supply for power supply. The DCS cabinet still uses dual - power supply, one is the feeder line of the thermal control power cabinet, and the other is the mains power supply. Since the dual - power supply used in the DCS system is at the millisecond level, seamless switching can be achieved. However, the existing power switching device is not convenient for maintenance. Most of the power switching devices are separately set at the bottom of the thermal control cabinet. To maintain the power switching device, the parts at the bottom of the thermal control cabinet need to be removed first, and then the power switching device can be overhauled. At this time, the maintenance personnel need to remove and take out the power switching device, and then install the power switching device after the overhaul, which makes the operation complicated. Summary of the Invention

Detailed Embodiments

[0018] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0019] Please refer to Figures 1 to 3, the present invention provides a dual - power - supply system for a thermal - control power cabinet, including a cabinet body 1, a power - supply switching box 2, and a mounting device 3. In this embodiment, the cabinet body 1 is hollow inside, the power - supply switching box 2 is a dual - power - supply switching device and is arranged inside the cabinet body 1. The dual - power - supply switching device 2 adopts a millisecond - level switching device, which can achieve non - interference switching of dual power supplies and does not affect the safety of the system, so that the power supply of the thermal - control power cabinet will not cause the failure of restarting the system due to mains failure or switching the power supply of the thermal - control power cabinet.

[0020] The mounting device 3 includes a support cover plate 31, a cover - plate moving component 32, a bottom slide rail 33, a first inclined connecting frame 34, a top slide rail 35, a second inclined connecting frame 36, a mounting cover plate 37, and a support limiting component 38. The support cover plate 31 is connected to the cabinet body 1 through the cover - plate moving component 32. The cover - plate moving component 32 drives the support cover plate 31 to move. The bottom slide rail 33 is fixedly installed on the support cover plate 31 and is located on one side of the support cover plate 31. One side of the first inclined connecting frame 34 is slidably connected to the bottom slide rail 33, and the other side of the first inclined connecting frame 34 is slidably connected to the top slide rail 35. One side of the second inclined connecting frame 36 is slidably connected to the bottom slide rail 33, and the other side of the second inclined connecting frame 36 is slidably connected to the top slide rail 35. The mounting cover plate 37 is fixedly installed on the top slide rail 35, and the power - supply switching box 2 is fixedly installed on the mounting cover plate 37.

[0021] The cover - plate moving component 32 includes a moving slide rail 321 and a moving slide seat 322. The moving slide rail 321 is fixedly installed on the cabinet body 1 and is located on the side of the cabinet body 1 close to the power - supply switching box 2. The moving slide seat 322 is slidably connected to the moving slide rail 321 and is fixedly connected to the support cover plate 31. In this embodiment, the moving slide rail 321 is of two - section type, and the fixed section of the moving slide rail 321 is installed on the cabinet body 1. The moving slide seat 322 is slidably installed on the moving slide rail 321, and then drives the moving slide seat 322 to slide on the moving slide rail 321, thereby driving the support cover plate 31 to move away from the cabinet body 1, and enabling the power - supply switching box 2 to be taken out.

[0022] A notch for installing the support cover plate 31 is formed on the outer side surface of the bottom of the cabinet body 1. The support cover plate 31 is matched with the notch on the side surface of the bottom of the cabinet body 1, so as to integrally seal the cabinet body 1. The cross section of the support cover plate 31 is in an "L" shape, and the horizontally extending part faces the direction of the cabinet body 1 for installing the bottom slide rail 33. The support cover plate 31 is slidably installed on the cabinet body 1 through the cover plate moving assembly 32. The cover plate moving assembly 32 drives the support cover plate 31 to move towards the side surface of the cabinet body 1. Since the power switch box 2 is installed on the support cover plate 31 through the installation cover plate 37, the power switch box 2 is driven to move out of the interior of the cabinet body 1. The support and limit assembly 38 is arranged between the support cover plate 31 and the installation cover plate 37 for connecting the support cover plate 31 and the installation cover plate 37, and enabling the installation cover plate 37 to move linearly when moving towards or away from the support cover plate 31, while keeping the installation cover plate 37 parallel to the support cover plate 31.

And the first inclined connecting frame 34 and the second inclined connecting frame 36 are cross - arranged. Thus, when maintenance is required, the installation cover plate 37 is pulled out in the direction away from the cabinet body 1 until the power switch box 2 is completely moved out of the cabinet body 1. The support and limit assembly 38 is opened, and the installation cover plate 37 installed with the power switch box 2 is lifted upwards, so that the angles of the first inclined connecting frame 34 and the second inclined connecting frame 36 are changed and they slide on the bottom slide rail 33 and the top slide rail 35 until the power switch box 2 moves to a suitable height, and then the first inclined connecting frame 34 and the second inclined connecting frame 36 are locked through the support and limit assembly 38, so as to facilitate the maintenance personnel to perform maintenance operations on the power switch box 2.

[0023] The first inclined connecting frame 34 includes a first inclined connecting rod 341 and a first sliding seat member 342. The first inclined connecting rod 341 is connected with the top slide rail 35 and the bottom slide rail 33 respectively through the first sliding seat member 342, and the first sliding seat member 342 drives the first inclined connecting rod 341 to slide.
