Description

Technical Field

[0001] This utility model belongs to the field of battery cabinet technology, and in particular relates to a UPS power supply cabinet. Background Technology

[0002] UPS, or Uninterruptible Power Supply, is a type of uninterrupted power supply containing energy storage. It is primarily used to provide uninterrupted power to equipment with high power stability requirements. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load; in this state, the UPS functions as an AC voltage regulator while simultaneously charging its internal battery. When the mains power is interrupted (power outage), the UPS immediately switches from the battery's DC power to the load via an inverter, continuing to supply 220V AC power to maintain normal operation and protecting the load's hardware and software from damage.

[0003] Patent No. CN223333894U discloses a UPS centralized power supply battery cabinet, including a main cabinet and two sets of semi-open auxiliary cabinets. The main cabinet includes two sets of covers and a back panel. The two sets of covers are arranged vertically with their opening sides facing each other. The back panel is fixedly connected to the middle rear side of the two sets of covers. A protective door is hinged to the front side of the lower cover, and a locking device is connected to the upper cover. Four main casters are fixedly connected to the four corners of the lower cover. The two auxiliary cabinets are arranged horizontally inside the main cabinet. However, in this technical solution, the batteries are placed directly flat on the rack, and the wires and signal lines connected to the batteries are laid directly on top of the batteries. This makes it very inconvenient for staff to perform operations such as battery positioning, monitoring, maintenance, and replacement. Furthermore, there is a risk of short circuits and fires caused by incorrect wiring connections during replacement. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when multiple batteries are stored in an existing battery cabinet, it is difficult to organize the connecting wires of the multiple batteries, which hinders the subsequent maintenance and replacement of the batteries.

[0005] The technical solution of this utility model is as follows: a UPS power supply cabinet includes a cabinet body and a cabinet door with multiple placement cavities inside, and a battery compartment. The battery compartment contains batteries and battery sensors. The battery compartment is equipped with a signal network port and a power interface. The battery compartments are evenly placed in the placement cavities of the cabinet body. A wire harness mounting rod is provided above each placement cavity.

[0027] like Figures 1-3 As shown, this embodiment provides a UPS power supply cabinet, including a cabinet body 1 with multiple internal placement cavities 3 and a cabinet door 2, and a battery compartment 4. The battery compartment 4 contains batteries 7 and battery sensors 8. The battery compartment 4 is equipped with a signal network port 5 and a power interface 6. The input line of the battery sensor 8 is connected to the positive and negative output terminals of the battery 7, the output line of the battery sensor 8 is connected to the signal network port 5, and the positive and negative terminals of the battery 7 are electrically connected to the power interface 6. The battery compartment 4 is evenly placed within the placement cavities 3 of the cabinet body 1. This embodiment encapsulates the batteries 7 and battery sensors 8 into a single unit using the battery compartment 4. When power supply maintenance or replacement is required, the faulty battery compartment 4 can be directly removed for individual repair. During this repair process, interference from other battery 7 connection harnesses can be effectively avoided, improving repair efficiency and reducing safety hazards caused by messy harnesses. Each placement cavity 3 has a harness mounting rod 9 above it. The wiring harness mounting rod 9 has a wiring harness groove 10, in which a signal transmission harness 11 and a power transmission harness 12 are fixedly laid. Each battery compartment 4 has a connecting branch line 13 for the signal transmission harness 11 and the power transmission harness 12. The tail end of the connecting branch line 13 is provided with a communication conversion connector 26 and a power connector 27, respectively. Each battery compartment 4 has a wire through hole 14 on the wiring harness mounting rod 9. The connecting branch line 13 passes through the wire through hole 14 and is plugged into the power interface 6 and the signal network port 5 on the battery compartment 4. By pre-burying the signal transmission harness 11 and the power transmission harness 12 in the wiring harness mounting rod 9, the above two types of harnesses do not need to be disassembled and repaired unless necessary. These connecting harnesses usually do not fail, allowing the staff to concentrate on the battery compartment 4, which has a higher failure rate, during maintenance. The one-to-one plugging of the connecting branch line 13 into the battery compartment 4 also facilitates the subsequent disassembly and replacement of individual battery compartments 4.

[0028] Both the battery sensor 8 and the battery 7 mentioned above can be directly purchased from commercially available mature products. Their hardware structure and working principle are existing technologies, so they will not be elaborated on in this article.

[0029] Specific work process

[0030] In this embodiment, the battery sensor 8 in each battery compartment 4 monitors the output current, voltage, internal resistance, temperature and other information of each battery 7. The monitoring equipment program automatically determines whether the battery 7 is in normal working condition based on this information. When a fault is detected in a battery 7, the monitoring equipment issues an alarm. The number of the battery sensor 8 in the battery compartment 4 can be displayed on the monitoring equipment to help the staff directly locate the faulty battery 7. Then, the staff only needs to disconnect the connecting branch line 13 connected to the battery compartment 4, remove the faulty battery compartment 4, replace the working battery compartment 4 with the working battery compartment 4, and plug in the connecting branch line 13 to complete the maintenance process of the cabinet 1, which is very convenient.

[0031] Specifically, the cabinet 1 also includes a communication box 15. The signal transmission harness 11 and power transmission harness 12 are both connected to the communication box 15. The communication box 15 contains a control module, a wireless transmission module, a signal output network port, and a power output interface. The signal transmission harness 11 and power transmission harness 12 are electrically connected to the control module, as are the wireless transmission module, signal output network port, and power output interface. The control module contains multiple control chips that receive information from the battery 7 collected by the battery sensor 8, generate electrical signals, and simultaneously transmit them wirelessly and wired to the signal output network port. The driving current of the battery 7 is supplied to the control module via the power transmission harness 12 and then transferred by the control module to the power output interface.

[0032] like Figure 4 As shown, specifically in this embodiment, the signal transmission harness 11 connects each battery compartment 4 in series, the multiple batteries 7 on the same layer are connected in series through the power transmission harness 12, and the batteries 7 on different layers are connected in parallel through the power transmission harness 12.

[0033] Specifically, such as Figure 5 As shown, the battery compartment 4 includes a compartment body 16 and a compartment cover 17. The compartment body 16 and the compartment cover 17 are fitted together to form a battery compartment 4 with a cavity structure. A battery sensor 8 and a battery 7 are disposed inside the battery compartment 4. A first abutment block 18 is provided on the inner wall of the battery compartment 4. The first abutment block 18 abuts against the side of the battery 7 to restrict the horizontal movement of the battery 7. A pressure rod 19 is detachably installed above the abutment block. The pressure rod 19 abuts against the top of the battery 7 to restrict the vertical movement of the battery 7. Through the cooperation of the first abutment block and the pressure rod 19, the battery 7 can be effectively fixed to the bottom of the battery compartment 4, preventing it from shaking inside the battery compartment 4 during transportation of the battery compartment 4 or the cabinet 1. The battery 7 is protected from damage caused by bumps, impacts, etc.

[0034] Specifically, the cabinet door 2 is equipped with a main switch 20, which is connected to the power transmission harness 12 and connected in series with the battery 7. In this embodiment, the main switch 20 is an air switch, which is used to provide protection for the power supply line of the battery 7. When the load is too large, causing the power supply of the battery 7 to be too large or the battery 7 to short-circuit, the main switch 20 will automatically trip to protect the circuit and equipment.

[0035] Specifically, the cabinet 1 has a detachable maintenance cover 21 on its surface, which is located above the communication box 15. The maintenance cover 21 can be removed and installed to quickly inspect the communication box 15 and its various structures, and can also be used to quickly test the signal transmission harness 11 and the power transmission harness 12.

[0036] Specifically, the cabinet door 2 is also provided with heat dissipation holes 22 for ventilation and heat dissipation inside the cabinet 1.

[0037] Specifically, such as Figure 6 As shown, the inner side of the cabinet door 2 is provided with a plurality of second abutment blocks 23. The second abutment blocks 23 are used to abut against the side of the battery compartment 4. The second abutment blocks 23 can effectively fix the battery compartment 4 in the cabinet body 1, preventing the battery compartment 4 from colliding with the inside of the cabinet body 1 when the cabinet body 1 moves, and also preventing the battery compartment 4 from sliding in the cabinet body 1 and causing pulling on the signal transmission harness 11 and the power transmission harness 12.

[0038] Specifically, the battery compartment 4 is provided with a handle on the side near the cabinet door 2, which makes it convenient for operators to quickly remove the battery compartment 4 from the cabinet 1.

[0039] Specifically, the cabinet 1 is provided with casters 25 at the bottom for quick movement of the cabinet 1.

[0040] It is worth noting that the control module and wireless transmission module mentioned in this embodiment can be directly purchased from existing mature electronic components on the market. For example, the control module can be a circuit board controlled by an STM32 series MCU; the wireless transmission module can be an industrial-grade CC1101 wireless module. The hardware structure and working principle of the above electronic components are all existing technologies, so they will not be described in detail in this article.

[0041] The above description is a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this utility model, should be covered within the protection scope of the claims of this utility model.
