Description

Technical Field

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

[0002] EPS is an emergency power supply that converts DC power into AC power, consisting of a charger, inverter, battery, isolation transformer, and transfer switch. It is mainly used to provide centralized power to emergency lighting and other lamps and important electrical equipment in the event of a fire or other emergency. Compared with UPS uninterruptible power supply, which has lower conversion efficiency and operates continuously for a long time, EPS emergency power supply has a higher performance-price ratio.

[0003] EPS emergency power supplies generate significant heat from some core components during operation, and high operating temperatures inevitably affect their lifespan. Therefore, EPS emergency power supplies should possess excellent heat dissipation and cooling capabilities. However, cabinet structures designed with air-cooling mechanisms often suffer from the problem that while the ventilation holes facilitate heat dissipation, they also allow large amounts of dust from the outside air to directly enter, leading to severe dust accumulation that significantly impacts equipment operation. This necessitates the installation of dust-blocking nets and other components. In harsh climates, these nets require frequent cleaning and replacement, but frequent opening of the cabinet also affects the internal equipment. Furthermore, existing EPS fire emergency power supply cabinets and heat dissipation mechanisms suffer from difficulties in production and assembly, as well as inconvenient periodic maintenance and repair. Utility Model Content

[0004] The purpose of this utility model is to provide an EPS fire emergency power supply cabinet structure, which facilitates the cleaning and maintenance of the heat dissipation components inside the emergency power supply cabinet by setting a double-layer side plate structure and a heat dissipation mechanism with a filter screen.

[0005] The technical solution adopted by this utility model is as follows: an EPS fire emergency power supply cabinet structure, including a cabinet frame, a hinged door and side panels. The side panels include an inner panel located on both sides of the cabinet frame and a mesh panel located on the outside of the inner panel and detached from the cabinet frame. A heat dissipation fan is provided in the cavity between the inner panel and the mesh panel. An exhaust structure is provided at the bottom of the cabinet frame. A pin structure is provided on the inner side of the inner panel to connect with the cabinet frame.

[0006] As a further feature of the above solution, the opening and closing door includes an operation door located on the front of the cabinet frame and a maintenance door located on the back. Both the operation door and the maintenance door include a lockable door body and an inner bolt door body with the same bolt structure as the inner panel. The lockable door body and the inner bolt door body are respectively hinged to the cabinet frame on one side.

[0007] As a further feature of the above solution, both the mesh plate and the inner plate are provided with air vents, and a filter screen is provided inside the air vents on the mesh plate.

[0008] As a further feature of the above scheme, the exhaust structure includes an airflow chamber, a vent located at the top of the airflow chamber and connecting to the inner cavity of the cabinet frame, and an exhaust port located on the outer wall of the airflow chamber and connecting to the outside.

[0009] As a further feature of the above scheme, the cabinet frame includes a main beam and several mounting plates with bolt holes.

[0010] Beneficial effects: The EPS fire emergency power supply cabinet structure of this utility model, by setting an openable door structure on the front and back, combined with a side panel structure that is easy to disassemble during assembly and maintenance, can facilitate the disassembly and assembly of the cabinet. Furthermore, the side panel is set as a double-layer structure, and the heat dissipation component of the cabinet in this embodiment is set in the double-layer cavity.

[0019] like Figure 1-6 The EPS fire emergency power supply cabinet structure shown includes a cabinet frame 1, a hinged door 2, and side panels 3. The side panels 3 include an inner panel 31 located on both sides of the cabinet frame 1 and a mesh panel 32 located on the outer side of the inner panel 31 and detached from the cabinet frame 1. A cooling fan 34 is provided in the cavity 33 between the inner panel 31 and the mesh panel 32. An exhaust structure 12 is provided at the bottom 11 of the cabinet frame 1. A pin structure 4 is provided on the inner side of the inner panel 31 to connect with the cabinet frame 1.

[0020] As a further provision of the above scheme, the opening and closing door 2 includes an operation door 21 located on the front of the cabinet frame 1 and a maintenance door 22 located on the back. Both the operation door 21 and the maintenance door 22 include a lockable door body 25 and an inner bolt door body 26 with the same bolt structure 4 as the inner panel 31. The lockable door body 25 and the inner bolt door body 26 are respectively hinged to the cabinet frame 1 on one side.

[0021] As a further feature of the above scheme, both the mesh plate 32 and the inner plate 31 are provided with air holes 30, and a filter screen 35 is provided inside the air holes 30 on the mesh plate 32.

[0022] As a further provision of the above scheme, the exhaust structure 12 includes an airflow cavity 121, a vent 132 located in the airflow cavity 121 and connected to the inner cavity of the cabinet frame 1 at the top of the airflow cavity 121, and an exhaust hole 123 located on the outer wall of the airflow cavity 121 and connected to the outside.

[0023] As a further feature of the above scheme, the cabinet frame 1 includes a main beam 13 and several mounting plates 15 with bolt holes 14.

[0024] refer to Figure 1-6 The fire emergency power supply cabinet structure shown in this embodiment features a double side panel 3 structure, placing the ventilation and heat dissipation structure between the inner panel 31 and the mesh panel 32 for easy cleaning by maintenance personnel. The cabinet frame 1 in this embodiment is mainly composed of several main beams 13 connected to form a square frame structure, which is then enclosed on all four sides by opening and closing doors 2 and side panels 3. The top and bottom 11 are fixedly installed with the main beams to form a closed cabinet structure. Figure 1-4The bottom 11 of the embodiment shown is also provided with an exhaust structure 12 with an airflow cavity 121. A vent 132 is opened at the top of the airflow cavity 121, which is the bottom 11 of the cabinet, so that the air inside the cabinet can enter the airflow cavity 121 through the vent 132 and then be discharged through the exhaust hole 123 provided on the side wall of the airflow cavity 121. This exhaust structure and the air inlet provided on the side plate 3 form an exchange of air inside the cabinet, thereby achieving the function of ventilation and cooling.

[0025] It is worth noting that, in the cabinet design of this embodiment, in order to facilitate the overall assembly and later maintenance of the cabinet, the opening and closing door 2 of this embodiment, as shown in the figure, is provided with an operation door 21 and a maintenance door 22. Both the operation door 21 and the maintenance door 22 are equipped with a lockable door body 25 and an inner bolt door body 26. The inner bolt door body 26 of this embodiment is provided with... Figure 5 The bolt structure 4 shown has a bolt body fixed on the inner bolt door 26. The bolt rod extends out relative to the cabinet frame 1 and is inserted into the limit position. The lockable door 25 is equipped with a lock cylinder structure, which locks with the inner bolt door 26. When the staff opens the door, they need to unlock the lock cylinder structure to open the lockable door 25 first. Then, the bolt structure 4 located at the upper and lower ends of the inner bolt door 26 can be released from the inside, so that the front and back of the cabinet can be opened, which is convenient for staff to operate or maintain.

[0026] When necessary, or during regular maintenance and cleaning of the heat dissipation structure, workers can press the elastic inserts with spring structures on the upper sides of the mesh panels 32 of the side panels 3 towards the center. The elastic inserts will release their connection to the cabinet frame 1. Then, the mesh panels 32 can be tilted outwards and lifted upwards, causing the inserts at the bottom of the mesh panels 32 to disengage from the inserts on the cabinet frame 1, thus allowing the mesh panels 32 to be disassembled. It is worth noting that after disassembling the mesh panels 32... Figure 4 As shown, the filter 35 inside the mesh plate 32 can be replaced to prevent dust accumulation from clogging the air vents 30 when the cooling fan 34 draws in outside air through the air vents 30 of the mesh plate 32 and the inner plate 31. In this embodiment, the filter 35 can be quickly replaced by inserting and pulling it out from the side. The cooling fan 34 in this embodiment is as follows: Figure 2 and Figure 3 As shown, a mounting rod is connected to the housing of the cooling fan 34. The mounting rod, as shown, also has bolt holes 14, allowing for installation or removal relative to the main beam 13. The inner plate 31 is installed via... Figure 3 As shown, the inner panel 31 extends from the side to connect to the cabinet frame 1 via a latch structure 4 for installation. When removing it, it is the same as the inner latch door 26. After opening the lockable door 25, it needs to be unlocked from the inside, and then the inner panel 31 can be removed from the side opening.

[0027] like Figure 3The cabinet frame 1 shown in this embodiment includes a main beam 13 and several mounting plates 15 with bolt holes 14. The main beam 13 is provided with several bolt holes 14. The mounting plates 15 are connected and installed on the main beam 13 through the bolt holes 14. Then, devices such as chargers, inverters, batteries, isolation transformers, and switching switches are installed on the mounting plates 15.
