Description

Technical Field

[0001] This utility model relates to the field of UPS power supply technology, and in particular to a UPS power supply dual-machine hot standby switching device. Background Technology

[0002] UPS, or Uninterruptible Power Supply, is a system designed to solve the problem of uninterrupted power supply. It connects a battery to the main unit and uses the main unit's inverter and other module circuits to convert AC power into DC power. It is mainly used to provide a stable and uninterrupted power supply to a single computer, computer network system, or other power electronic equipment, and has three basic functions: voltage stabilization, filtering, and uninterruption.

[0003] In circulating water and wastewater treatment systems, equipment such as pumps, fans, and control systems (e.g., PLCs and instruments) are susceptible to problems such as process interruption, water quality deterioration, and equipment damage if a power outage occurs suddenly. UPS systems instantly switch to battery power when the power grid fails or voltage fluctuates, ensuring uninterrupted equipment operation and maintaining process continuity. In the field of circulating water and wastewater treatment, UPS is not only a "backup power supply" but also a core infrastructure that ensures process safety, environmental compliance, and equipment lifespan. Its value lies in transforming the risk of power outages from "catastrophic shutdowns" to "controllable emergency transitions" through the triple functions of "continuous power supply, power optimization, and safety control," making it an indispensable part of industrial automation and green production.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing UPS uninterruptible power supply devices with redundant dual units usually require the same model and capacity, and parallel operation needs to be achieved through communication protocols and complex control strategies. This leads to the need to match the original model when expanding or replacing equipment in practical applications, and it is difficult to be compatible between different brands. Then, multiple sets of bolts are used to fix it. In scenarios such as upgrading old equipment and integrating heterogeneous systems, there are limitations such as poor adaptability and high transformation costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the redundant dual units of the existing UPS uninterruptible power supply must be of the same model and capacity, the equipment is realized through communication and control, and it also needs to be fixed by multiple sets of bolts to ensure the normal operation of the UPS uninterruptible power supply. To this end, we propose a UPS power supply dual-unit hot standby switching device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a UPS power supply dual-machine hot standby switching device, comprising: a power supply assembly, a fixing assembly installed inside the power supply assembly, the power supply assembly including a protective box, a partition plate fixedly connected to the inner wall of the protective box, a mounting plate fixedly connected to one end of the partition plate, the mounting plate being disposed inside the protective box, a static switch fixedly connected to one side of the mounting plate, one end of the static switch being electrically connected to the UPS power supply body, the UPS power supply body being disposed inside the protective box, a box cover being installed on the upper end of the protective box, the fixing assembly including a limit strip, a fixing frame slidably connected to the outer surface of the limit strip, a movable groove being opened inside the fixing frame, a fixing plate being installed in the movable groove, a spring being elastically connected between the inner bottom surface of the fixing frame and the fixing plate, a lower pressure plate being disposed above the limit strip, an adjusting rod being disposed at the upper end of the lower pressure plate, and a box cover being threadedly connected to the upper end of the adjusting rod.

[0007] Preferably, a fan is installed on the inner wall of the protective box, ventilation slots are provided at both ends of the protective box and filter plates are installed in the ventilation slots, mounting holes A are opened on the partition plate and mounting holes B are opened on the mounting plate, the fan corresponds to the filter plate, and the filter plate corresponds to mounting holes A and B.

[0008] This is to increase the heat dissipation performance of the entire device, so that during use, the air inside the protective box can circulate with the outside air through the fan and filter plate.

[0009] Preferably, an anti-slip pad is fixedly connected to the bottom of the protective box, and the UPS power supply body is placed on the anti-slip pad;

[0010] This is used to increase the friction between the protection box and the UPS power supply body, preventing the UPS power supply body from shaking inside the protection box.

[0011] Preferably, the limit strips are provided in multiple sets, and each set of limit strips is provided with a pair, so that the limit strips can be easily installed on the inner wall of the protective box and the outer surface of the partition plate;

[0012] It is designed to facilitate the installation of the mounting bracket in a designated location, while also allowing operators to easily disassemble it.

[0013] Preferably, a limiting plate is fixedly connected to one end of the fixed plate, the movable groove corresponds to the limiting plate, and a protective strip is fixedly connected to the other end of the fixed plate, with multiple sets of grooves opened on the protective strip;

[0014] This is used to limit the position of the mounting plate while increasing the friction between the mounting plate and the UPS power supply body.

[0015] Preferably, the lower pressure plate has four sets of through slots, the limit strip corresponds to the through slots, and a soft pad is fixedly connected to the bottom surface of the lower pressure plate, with the UPS power supply body corresponding to the soft pad.

[0016] While facilitating the normal vertical linear movement of the pressure plate, the soft pad prevents the pressure plate from directly contacting the UPS power supply body, thus preventing the pressure plate from scratching the UPS power supply body casing.

[0017] Preferably, a mounting sleeve is fixedly connected to the upper surface of the lower pressure plate, and a mounting ring is fixedly connected to the lower end of the adjusting rod, with the mounting ring installed inside the mounting sleeve;

[0018] This is used to ensure that when the adjusting rod is rotated, the lower pressure plate will not rotate with it, but will only move up and down in a straight line.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] In this utility model, during actual use, the fixing bracket is first installed in the designated position using the limiting strip. Then, the UPS power supply body is placed inside the protective box, and the protective box, power cord, and static switch are connected together. Next, the box cover is installed on the protective box, and the adjusting rod is rotated to drive the lower pressure plate downward. The lower pressure plate applies a downward force to the UPS power supply body, while the fixing plate provides support to both sides of the UPS power supply body, thereby achieving the limiting operation of the UPS power supply body.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a UPS power supply dual-machine hot standby switching device, including: a power supply assembly 1, a fixing assembly 2 installed inside the power supply assembly 1, the power supply assembly 1 including a protection box 11, a partition plate 12 fixedly connected to the inner wall of the protection box 11, a mounting plate 13 fixedly connected to one end of the partition plate 12, the mounting plate 13 being disposed inside the protection box 11, a static switch 14 fixedly connected to one side of the mounting plate 13, and a UPS power supply body 15 electrically connected to one end of the static switch 14. The power supply body 15 is located inside the protection box 11. The protection box 11 is equipped with a box cover 17. The fixing component 2 includes a limiting strip 21. A fixing frame 22 is slidably connected to the outer surface of the limiting strip 21. A movable groove 23 is opened inside the fixing frame 22. A fixing plate 24 is installed in the movable groove 23. A spring 25 is elastically connected between the bottom surface of the fixing frame 22 and the fixing plate 24. A lower pressure plate 26 is provided above the limiting strip 21. An adjusting rod 27 is provided at the upper end of the lower pressure plate 26. The upper end of the adjusting rod 27 is threadedly connected to the box cover 17.

[0030] First, remove the cover 17. Then, use the limiting strip 21 to limit the installation of the fixing frame 22. Next, install the UPS power supply body 15 into the protective box 11. During installation, connect the UPS power supply body 15 to the external connection cable and the static switch 14. When installing the UPS power supply body 15 into the protective box 11, the UPS power supply body 15 will press against the fixing plate 24, and then the fixing plate 24 will retract into the movable groove 23. Then, under the action of the spring 25, a reverse force is applied to the fixing plate 24, thereby performing a preliminary clamping and fixing operation on the UPS power supply body 15. Then, install the cover 17 onto the protective box 11. After the cover 17 is installed, rotate the adjusting rod 27. The adjusting rod 27 drives the lower pressure plate 26 to move downward. Finally, the lower pressure plate 26 applies a downward force to the UPS power supply body 15, thereby fixing the UPS power supply body 15 a second time. Because of the static switch 14, the operator can use UPS power supply bodies 15 of different specifications together.

[0031] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a UPS power supply dual-machine hot standby switching device, a fan 16 is installed on the inner wall of the protection box 11, ventilation slots are provided at both ends of the protection box 11 and filter plates 111 are installed in the ventilation slots, mounting holes A121 are opened on the partition plate 12 and mounting holes B131 are opened on the mounting plate 13, the fan 16 corresponds to the filter plate 111, the filter plate 111 corresponds to the mounting holes A121 and B131, an anti-slip pad 112 is fixedly connected to the bottom surface of the inner wall of the protection box 11, the UPS power supply body 15 is placed on the anti-slip pad 112, multiple sets of limit strips 21 are provided, each set of limit strips 21 is provided with a pair, and the limit strips 21 are convenient to be installed on the inner wall of the protection box 11 and the outer surface of the partition plate 12.

[0032] When assembling the power supply unit, the installer can choose to add various inspection instruments and sensors according to the actual usage. When the internal temperature of the protection box 11 is too high, the fan 16 starts to accelerate the airflow inside the protection box 11. Because of the filter plate 111, the air entering the protection box 11 can be filtered. And because of the mounting holes A121 and B131, the air inside the protection box 11 can circulate normally. By setting the anti-slip pad 112, the friction between the bottom surface of the protection box 11 and the UPS power supply body 15 can be effectively increased.

[0033] Reference Figures 1 to 5As shown, this utility model provides a technical solution: a UPS power supply dual-machine hot standby switching device, a limiting plate 241 is fixedly connected to one end of a fixed plate 24, a movable groove 23 corresponds to the limiting plate 241, a protective strip 242 is fixedly connected to the other end of the fixed plate 24, a plurality of grooves 243 are provided on the protective strip 242, four through grooves 261 are provided on the lower pressure plate 26, a limiting strip 21 corresponds to the through grooves 261, a soft pad 263 is fixedly connected to the bottom surface of the lower pressure plate 26, the UPS power supply body 15 corresponds to the soft pad 263, an installation sleeve 262 is fixedly connected to the upper surface of the lower pressure plate 26, an installation ring 271 is fixedly connected to the lower end of the adjusting rod 27, and the installation ring 271 is installed inside the installation sleeve 262.

[0034] By adding a limiting plate 241 to the fixed plate 24, the fixed plate 24 can be effectively limited. Then, a protective strip 242 is added to the other end of the fixed plate 24. The protective strip 242 is made of elastic material, which not only increases the friction between the fixed plate 24 and the UPS power supply body 15, but also effectively prevents the fixed plate 24 from scratching the UPS power supply body 15. At the same time, with the cooperation of the through groove 261 and the limiting strip 21, the lower pressure plate 26 can not only move up and down, but also be guided. With the help of the mounting sleeve 262 and the mounting ring 271, the lower pressure plate 26 can only move in a straight line up and down.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
