Description

Technical Field

[0001] The utility model relates to the technical field of emergency power supply, in particular to an air-cooled emergency lighting power supply box. Background Art

[0002] Emergency lighting refers to a type of lighting that can effectively illuminate and display evacuation routes, or can continuously illuminate without interruption when the normal lighting power supply fails. It is widely used in public places and places where lighting cannot be interrupted. Emergency lighting requires the use of a power supply box for centralized power supply. Most of the existing centralized power supply boxes used for emergency lighting are set in a closed space;

[0003] In the Chinese utility model patent document with the announcement number: CN220233811U, the patent name is a waterproof air-cooled emergency lighting power supply box, a technical solution is proposed: an air inlet mechanism and an air outlet mechanism are arranged in the power supply box, and the air in the box is facilitated to circulate through the cooperation of the air inlet mechanism and the air outlet mechanism, so that the various electronic devices in the box can be cooled to ensure the stability of their working environment;

[0004] However, the above technical solution has the following disadvantages:

[0005] 1. The water inlet and outlet shells used in the air inlet and outlet mechanisms assembled on both sides of the power supply box are fixed to the side walls of the inner cavity of the power supply box by welding. When the power supply box is produced and assembled, the welding and fixing assembly method increases the difficulty of assembling the air inlet and outlet mechanisms, and prolongs the assembly time of the power supply box during the production process;

[0006] 2. The power supply box is provided with air inlet and outlet holes on its side wall. In a dangerous environment, external water can easily enter the water-blocking compartment shell through the air inlet and outlet holes. After the water level drops, the emergency drain port needs to be manually operated to discharge the remaining water in the water-blocking compartment shell, thereby ensuring the heat dissipation performance of the device. The manual drainage method increases the complexity of the product during use, resulting in inconvenience in the application of the product. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: an air-cooled emergency lighting power supply box, comprising a box body 1, a box door 2 for closing the box body 1 is hingedly connected to the front side wall of the box body 1, a switch lock is installed between the box door 2 and the box body 1, and the box door 2 and the box body 1 are closed and locked by the set switch lock, a battery 3 is fixedly installed at the bottom of the inner cavity of the box body 1, and the battery 3 is used to power emergency lighting equipment, and an equipment mounting frame 4 is fixedly installed in the inner cavity of the box body 1, and the equipment mounting frame 4 is used for assembling electrical equipment such as switches.

[0021] like Figure 2 As shown in the figure, assembly holes 5 are respectively opened on the left and right side walls of the box body 1, and the assembly holes 5 on both sides are respectively used for the installation and fixation of the air guide mechanism 6. The assembly holes 5 on both sides are distributed in a position with the left side lower and the right side higher. With the opening position of the assembly holes 5 with the left side lower and the right side higher, the air entering the box body 1 is circulated in the box body 1 and then discharged, so as to fully dissipate the heat of the switch electrical equipment and the battery 3 in the equipment mounting frame 4.

[0022] like Figure 3 As shown in the figure, the air guide mechanism 6 includes an assembly shell 61, in which an assembly groove 62 is integrally formed, and there is a certain distance between the assembly groove 62 and the side wall of the assembly shell 61. A ventilation hole 63 penetrating the assembly shell 61 is provided at the bottom of the assembly groove 62, and the size of the assembly shell 61 is adapted to the size of the assembly hole 5. A fan mounting frame 64 is fixedly assembled in the assembly groove 62 by fixing bolts, and an emergency chamber 65 is formed between the fan mounting frame 64 and the assembly shell 61. A fan 66 is fixedly assembled in the fan mounting frame 64, and the fan 66 is electrically connected to an external power supply. The external air is sucked into the box body 1 from the ventilation hole 63 through the fan 66, or the air in the box body 1 is discharged from the ventilation hole 63. A sealing component 7 is assembled in the fan mounting frame 64, and the fan mounting frame 64 is sealed by the provided sealing component 7, thereby enhancing the waterproof performance of the emergency chamber 65 and the box body 1 as a whole.

[0023] Compared with the traditional products, this product modularizes the structure of ventilation and heat dissipation inside the box 1, adopts the method of matching and assembling the assembly shell 61 with the fan mounting frame 64, and then the assembly shell 61 and the box 1 are fixed by snap connection, and it is no longer necessary to adopt the traditional connection method of setting the air inlet and outlet water-blocking bin and its installation position for welding and fixing, which simplifies the overall installation process of the box 1 and improves the assembly efficiency of the product;

[0024] Secondly, this product adopts the design of hidden ventilation holes 63. Compared with the traditional ventilation and heat dissipation method of opening air inlet and air outlet holes on the side wall of the power supply box, the hidden ventilation holes 63 are more conducive to waterproofing the external environment, and simplify the drainage process. There is no need to set up an emergency drain port to manually drain the device. The water that enters between the fan mounting bracket 64 and the assembly shell 61 can be directly discharged through the ventilation holes 63.

[0025] like Figure 3 As shown in the figure, the sealing assembly 7 includes a first installation cavity 71 and a second installation cavity 72. The first installation cavity 71 and the second installation cavity 72 are respectively opened in the left and right side walls of the fan mounting frame 64. The left and right side walls of the fan mounting frame 64 are respectively opened with annular holes connected with the inner cavity thereof. The annular holes are used for the fluid of air. The first installation cavity 71 and the second installation cavity 72 are respectively embedded with a sealing film 73. The sealing film 73 adopts a waterproof and breathable film with flame retardant properties. The sealing film 73 is provided to seal the fan mounting frame 64, thereby improving the overall waterproof performance of the box body 1. The sealing film 73 can waterproof the box body 1 without blocking the passage of air, which is convenient for the air to circulate in the box body 1 and dissipate heat in the box body 1.

[0026] The fan blades of the fan 66 located in the air guide mechanism 6 on the left and right sides of the box 1 are set in a direction that one side drives the external air from the outside into the box 1, and the other side discharges the air in the box 1 to the outside, thereby realizing the internal circulation of air in the box 1.

[0027] Working principle: During use of the device, the battery 3 arranged in the box body 1 is used to power the emergency lighting equipment, and the equipment mounting frame 4 is used for the assembly of switches and other control electrical equipment. Through the action of the fan 66 in the air guide mechanism 6 arranged on the left and right side walls, the air is driven to circulate and be discharged from the box body 1, and the electronic equipment assembled in the box body 1 is cooled to ensure the stability of its working environment. The air guide mechanism 6 and the box body 1 are installed in a modular manner, which improves the overall assembly and installation efficiency of the box body 1. At the same time, a hidden ventilation hole 63 is provided to cooperate with the emergency cavity 65 formed between the fan mounting frame 64 and the assembly shell 61. When an external water source flows into the emergency cavity 65 in a dangerous environment, the water can be temporarily stored through the emergency cavity 65, effectively preventing external water from entering the box body 1, and the water can be automatically discharged to the outside through the ventilation hole 63 after the water level drops. There is no need to manually drain the water through the emergency drain port, which further improves the overall waterproof performance of the box body 1.
