Description

Technical Field

[0001] The utility model relates to the technical field of power cabinets, in particular to an EPS power cabinet convenient for maintenance. Background Technique

[0002] EPS refers to an emergency power supply, which is an emergency power supply adopted for emergency lighting, accident lighting, and fire-fighting facilities in important buildings nowadays. It mainly consists of an input unit, an output unit, a charging module, an EPS battery pack, an inverter, a monitor, an output switching device, etc. This system can provide emergency power supply in an emergency state.

[0003] The factors affecting the performance of EPS are not only closely related to circuit design and component quality, but also have a significant relationship with the structure of the EPS cabinet. As a support system for circuit modules, the cabinet structure plays an important role in the EPS power supply system. For example, a modular EPS cabinet disclosed in Patent CN205960775U provides an EPS cabinet with clear wiring, convenient maintenance, good heat dissipation effect, and high modularity.

[0004] However, in the prior art, due to the large weight of the EPS battery pack of medium and large-sized EPS power supplies and the power control module itself, when it is necessary to repair the EPS battery pack and the power control module of the EPS power supply, it is necessary to manually disassemble these devices from the cabinet, which is time-consuming and laborious, thus reducing work efficiency and being inconvenient for people to use. Therefore, we propose an EPS power cabinet convenient for maintenance. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides two technical solutions: Embodiment 1

[0025] An EPS power supply cabinet convenient for maintenance, including a power supply cabinet body 1, and a plurality of installation components 2 for installing EPS battery packs are sequentially arranged from top to bottom in the power supply cabinet body 1;

[0026] The installation component 2 includes a bearing frame 21 fixed to the inner wall of the power supply cabinet body 1, a tray 23 is slidably installed on the bearing frame 21 through a slide rail component 22, two brackets 24 are arranged above the tray 23, and a limit frame 25 is fixed on the brackets 24 for clamping and fixing the two sides of the EPS battery pack;

[0027] One bracket 24 is fixed on the tray 23, and the other bracket 24 is driven to move by a moving mechanism 26 arranged on the tray 23;

[0028] The sliding rail assembly 22 includes a first sliding groove 221 formed on the inner side wall of the bearing frame 21 and a first sliding block 222 fixed to the bottom end of the tray 23. The first sliding block 222 is slidably clamped in the first sliding groove 221. A second sliding groove 223 is formed at the top of the bearing frame 21. A sliding locking assembly 224 is connected to the bottom of the tray 23 through a connecting rod for slidably clamping and locking with the second sliding groove 223. Embodiment 2

[0029] The main difference from Embodiment 1 is that:

[0030] An EPS power cabinet convenient for maintenance. The sliding locking assembly 224 includes a triangular frame 2241 fixed to the connecting rod at the bottom of the tray 23. A locking bolt 2242 is threadedly connected to the triangular frame 2241. The bottom end of the locking bolt 2242 is connected to a second sliding block 2243 that is movably clamped inside the second sliding groove 223. The use of the second sliding block 2243 movably clamped inside the second sliding groove 223 facilitates the sliding of the second sliding block 2243 in the second sliding groove 223 and can lock and fix the triangular frame 2241 and the bearing frame 21 by tightening the locking bolt 2242 on the triangular frame 2241, facilitating the locking and installation of the position of the bearing frame 21 after movement and adjustment; the inner surface size of the limiting frame 25 is adapted to the outer surface size of the EPS battery pack. Both ends of the EPS battery pack are respectively embedded and clamped inside the limiting frame 25, and the EPS battery pack is supported and clamped and fixed by the limiting frame 25; the moving mechanism 26 includes a limiting sleeve 262 rotatably installed on the tray 23 through a bearing and a limiting rod 261 fixed to the bottom of the bracket 24. The limiting rod 261 is movably sleeved on the limiting sleeve 262. A cylinder 263 is fixed to the tray 23. The output end of the cylinder 263 is connected to one of the brackets 24. Starting the cylinder 263 can drive the bracket 24 to move, thereby driving the limiting frame 25 to move, and further clamping and fixing the EPS battery pack through the cooperation of the two limiting frames 25; a plurality of heat dissipation nets 3 are respectively installed on the outer walls on both sides of the power cabinet body 1 for ventilation and heat dissipation inside the power cabinet body 1. The heat dissipation nets 3 penetrate through the housing of the outer walls on both sides of the power cabinet body 1; a maintenance door 4 is hingedly installed on one side of the front of the power cabinet body 1 through a hinge. A handle is fixedly installed on the front of the maintenance door 4, facilitating the later maintenance and repair of the inside of the power cabinet body 1.

[0031] When the EPS power cabinet that is convenient for maintenance is in use, a plurality of installation components 2 are arranged in the power cabinet body 1 for installing the EPS battery pack. The installation component 2 includes a bearing frame 21, a slide rail component 22, etc. By setting the slide rail component 22, the first slider 222 slides in the first chute 221, and the sliding locking component 224 slides in the second chute 223, which can facilitate the extraction of the tray 23 from the inner side of the power cabinet body 1 during maintenance, so as to extract the EPS battery pack installed above the tray 23, facilitating people to carry out maintenance. In addition, two brackets 24 are installed above the tray 23 of the present utility model. One bracket 24 is fixed, and one bracket 24 is driven to move by the moving mechanism 26. Thus, the limiting frames 25 on the two brackets 24 cooperate to clamp and fix the EPS battery pack. Through the setting of the limiting frames 25, the EPS battery pack can be quickly released from the fixation and removed after being extracted by using snap-in installation, facilitating people to carry out maintenance.
