Description

Technical Field

[0001] This utility model relates to the field of emergency power supply cabinet technology, specifically an EPS fire emergency power supply cabinet. Background Technology

[0002] An EPS emergency power supply system mainly consists of a rectifier charger, battery bank, inverter, transfer switch, and system controller. The inverter is the core component, typically using a DSP or single-chip CPU for SPWM modulation control to achieve a good AC waveform output. The rectifier charger charges the battery bank when the mains input is normal. The inverter converts the DC power stored in the battery bank into AC power when the mains power is abnormal, providing a stable and continuous power supply to the load equipment. The transfer switch ensures smooth switching between mains power and inverter output. The system controller provides real-time control of the entire system, can issue fault alarm signals and receive remote linkage control signals, and can be remotely monitored by a host computer via a standard communication interface.

[0003] EPS fire emergency power supply cabinets integrate various electrical components such as inverters, battery packs, transfer switches, and control modules. Power transmission and signal connections between these components, as well as between the equipment and external loads, require numerous cables. However, current EPS fire emergency power supply cabinets on the market have significant shortcomings in cable management: the numerous cables inside the cabinet are often not clearly separated, and cables with different functions, such as power cables, control cables, and signal cables, are often mixed together.

[0004] This lack of differentiation in cable arrangement not only leads to a chaotic internal cabinet layout and increases the difficulty of later maintenance and repair, but more importantly, during equipment installation, commissioning, and daily use, cables are prone to tangling, compression, and pulling. When components inside the cabinet shift due to vibration, temperature changes, or minor external impacts, the pulling force acts directly on the interface between the cable and the connector. Over time, this can easily cause cable joints to loosen, poor contact, or even cause the cable to detach from the connected component. Once such problems occur, they may cause power transmission interruptions, signal loss, and other malfunctions. In severe cases, it can prevent the EPS fire emergency power supply cabinet from starting or operating normally in emergencies, losing its emergency protection function and posing a significant fire safety hazard. Summary of the Invention

[0005] The purpose of this utility model is to provide an EPS fire emergency power supply cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an EPS fire emergency power supply cabinet, comprising a cabinet body, an installation cavity being provided inside the cabinet body, a plurality of cable inlets being provided on the bottom surface of the installation cavity, and a cable protection assembly being fixedly installed on the lower part of the inner wall of the installation cavity at a position opposite to the cable inlets. The cable protection assembly includes a mounting base, a fixing block, a lower clamp, and an upper clamp. The mounting base is fixedly installed on the inner wall surface of the installation cavity, and a buffer groove is provided on the surface of the mounting base. The fixing block is movably connected in the buffer groove, and the top and bottom of the fixing block are connected to the inner wall of the buffer groove through the buffer assembly. The lower clamp is fixedly connected below the front end of the fixing block, and the upper clamp is movably connected to the front end surface of the fixing block directly above the lower clamp.

[0007] Preferably, the mounting base surface is provided with a sliding groove above the lower clamp, and the rear end of the upper clamp is fixedly connected to a slider adapted to the sliding groove, and the slider is slidably connected in the sliding groove.

[0008] Preferably, the lower clamping body has a rotating position on its surface, and the upper clamping body has a locking opening at a position opposite to the rotating position. A locking element for locking in conjunction with the locking opening is rotatably connected within the rotating position.

[0009] Preferably, the buffer assembly includes a guide rod and a buffer spring. The guide rod is fixedly connected to the upper and lower ends of the surface of the fixed block. A guide hole for the movement of the guide rod is opened in the buffer groove. A buffer spring is sleeved on the surface of the guide rod, and the upper and lower parts of the buffer spring resist the surface of the buffer groove and the surface of the fixed block, respectively.

[0010] Preferably, both the lower clamp and the upper clamp have arc-shaped openings facing each other, and the upper clamp is fixedly connected to a clamping block at the arc-shaped opening by a compression spring.

[0011] Preferably, the locking element includes a threaded rod and a locking block. The threaded rod rotates within a rotating position below its surface. The threaded rod rotates towards the locking port through the rotating position and is threadedly connected to the locking block. The bottom surface of the locking block contacts the top surface of the upper clamping body.

[0012] Preferably, the inner wall of the mounting cavity is longitudinally arranged and snapped with multiple support plates above the cable protection assembly, and the front and rear surfaces of the cabinet are fixedly connected to a door by hinges at opposite positions in the mounting cavity, with a storage box fixedly installed inside the door.

[0013] Beneficial effects

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by installing cable protection components inside the cabinet, can clearly distinguish and secure cables with different functions, such as power cables, control cables, and signal cables, entering the cabinet. The mating structure of the lower and upper clamps can adaptively clamp the cables according to their size characteristics, achieving classified cable arrangement. This classified management method completely changes the chaotic situation of mixed cable arrangement in traditional cabinets, making the cabinet space layout more orderly and significantly improving the utilization rate of the cabinet space, reserving sufficient and reasonable space for the installation and operation of other electrical components.

[0016] 2. The buffer assembly in the cable protection system plays a crucial role in cushioning and shock absorption. When components inside the cabinet shift due to vibration, temperature changes, or minor external impacts, the fixing block, through the buffer assembly, moves within the buffer groove to absorb and mitigate the impact of external forces. Simultaneously, the lower and upper clamps firmly hold the cables in place, and the elasticity of the clamping blocks and compression springs prevents cables from becoming tangled, squeezed, or pulled within the cabinet. This fundamentally reduces the probability of loose cable joints, poor contact, and cables detaching from connected components, ensuring the stability of power transmission and signal connections. It also ensures the equipment can operate stably and continuously in emergencies such as abnormal mains power, fully leveraging its emergency protection function. Attached Figure Description

[0029] like Figure 1-4 This is a structural schematic diagram of an EPS fire emergency power supply cabinet according to a preferred embodiment of the present invention. In this embodiment, the EPS fire emergency power supply cabinet includes a cabinet body 1, which is made of high-quality cold-rolled steel plate, possessing good mechanical strength and protective performance, effectively resisting external impacts and dust intrusion. An installation cavity 11 is provided inside the cabinet body 1. The spatial layout of the installation cavity 11 facilitates disassembly and replacement during later maintenance and repair. Multiple support plates 13 are arranged longitudinally and interlocked, dividing the cavity into upper and lower main areas. These support plates 13 are made of insulating material, possessing good electrical insulation performance, effectively preventing the risk of leakage between electrical components. A cable inlet 12 is provided on the bottom surface of the installation cavity 11 to facilitate the introduction of various cables. Multiple support plates 13 are arranged longitudinally and interlocked above the cable protection assembly 2 on the inner wall of the installation cavity 11.

[0030] In this embodiment, the front and rear surfaces of the cabinet 1 are fixedly connected to the door 3 via hinges at opposite positions in the mounting cavity 11. The door 3 adopts a double-layer steel plate structure with fireproof and heat-insulating material filled in between, which not only has good fire resistance but also provides a certain degree of sound and heat insulation. This is existing technology and will not be described in detail. A storage box 31 is fixedly installed on the inside of the door 3. The storage box 31 is used to store some commonly used maintenance tools and spare parts, such as screwdrivers, wrenches, spare fuses, etc., for easy access by staff during on-site maintenance and repair.

[0031] In this embodiment, the cable protection assembly 2 is installed on the lower part of the inner wall of the mounting cavity 11, opposite to the inlet 12, for protecting and classifying the cables entering the cabinet. It mainly consists of a mounting base 21, a fixing block 22, a lower clamp 23, and an upper clamp 24.

[0032] Mounting base 21 is fixedly installed on the inner wall surface of mounting cavity 11. It is made of high-strength aluminum alloy, which is lightweight and high-strength. A buffer groove 211 is provided on the surface of mounting base 21. The shape and size of buffer groove 211 are adapted to fixed block 22, and fixed block 22 can move freely in buffer groove 211.

[0033] The top and bottom of the fixing block 22 are connected to the inner wall of the buffer groove 211 via a buffer assembly 26. The buffer assembly 26 can effectively absorb and mitigate the impact of external forces on the cable. A lower clamp 23 is fixedly connected to the lower front end of the fixing block 22. The lower clamp 23 is made of insulating rubber material, which has good flexibility and anti-slip properties, and can effectively protect the cable sheath from scratches. An upper clamp 24 is movably connected to the front surface of the fixing block 22 directly above the lower clamp 23. The upper clamp 24 is also made of insulating rubber material.

[0034] In this embodiment, the surface of the mounting base 21 is located above the lower clamp 23 and has a groove 221. The rear end of the upper clamp 24 is fixedly connected to a slider 242 that matches the groove 221, and the slider 242 is slidably connected within the groove 221. This connection method allows the upper clamp 24 to slide up and down along the groove 221, facilitating the adjustment of the distance between the upper clamp 24 and the lower clamp 23 according to the diameter of the cable, thereby achieving clamping and fixing of cables of different specifications.

[0035] In this embodiment, the lower clamping body 23 has a rotating position 231 on its surface, and the upper clamping body 24 has a locking opening 241 located opposite to the rotating position 231. A locking member 25 for engaging with the locking opening 241 is rotatably connected within the rotating position 231. In this embodiment, the locking member 25 includes a threaded rod 251 and a locking block 252.

[0036] When it is necessary to clamp the cable, first place the cable on the lower clamp 23, and then slide the upper clamp 24 along the slide groove 221 via the slider 242, so that the upper clamp 24 is close to the lower clamp 23 and clamps the cable. Next, rotate the threaded rod 251, and the threaded rod 251 rotates through the rotating position 231 to flip towards the locking port 241 and is threadedly connected to the locking block 252. The bottom surface of the locking block 252 contacts the top surface of the upper clamp 24, thereby firmly locking the upper clamp 24 onto the lower clamp 23 and preventing the cable from loosening.

[0037] In this embodiment, the buffer assembly 26 includes a guide rod 261 and a buffer spring 262. The guide rod 261 is fixedly connected to the upper and lower ends of the surface of the fixing block 22, and a guide hole 212 for the movement of the guide rod 261 is provided in the buffer groove 211. The buffer spring 262 is sleeved on the surface of the guide rod 261, and the upper and lower parts of the buffer spring 262 resist the surface of the buffer groove 211 and the surface of the fixing block 22, respectively.

[0038] When components inside the cabinet shift due to vibration, temperature changes, or minor external impacts, the fixed block 22 will move within the buffer groove 211 under the action of the buffer assembly 26. The guide rod 261 slides within the guide hole 212, providing guidance and ensuring smooth movement of the fixed block 22. The buffer spring 262 absorbs and mitigates the impact of external forces, effectively protecting the cable from excessive external pulling and preventing problems such as loose cable joints and poor contact.

[0039] In this embodiment, both the lower clamp 23 and the upper clamp 24 have arc-shaped openings 27 facing each other. The shape of the arc-shaped openings 27 is adapted to the shape of the cable, which can better fit the cable and improve the clamping effect. The upper clamp 24 is fixedly connected to the clamping block 271 at the arc-shaped opening 27 by a compression spring 272.

[0040] The clamping block 271 is made of soft rubber material. Under the action of the compression spring 272, the clamping block 271 can press firmly against the cable, further enhancing the clamping force on the cable. At the same time, the elasticity of the compression spring 272 can also adapt to the cable's thickness variation within a certain range, ensuring a good clamping effect for cables of different specifications.

[0041] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
