Abstract
Description
Technical Field

[0002] Emergency power supplies are devices that provide power when the main power supply fails or is unavailable. They are mainly used to provide continuous power to mission-critical loads to ensure uninterrupted operation of important equipment and services.
[0003] In order to cope with various application scenarios, the types of emergency power supplies have also developed in a diversified manner. Among them, EPS emergency power supply is an emergency power supply device that is mainly used for fires in buildings or other emergency situations to provide centralized power supply for various lamps such as emergency lighting (including single-input and single-output metal halide lamps and sodium lamps). Common EPS emergency power supplies usually include a power supply box and a power system component placed in the power supply box. Among them, the power system component is the core part of the EPS emergency power supply. When the EPS emergency power supply is used for a long time, the power system components in the power supply box will generate high heat. At present, most EPS emergency power supplies only use blinds on the power supply box for passive heat dissipation. In an environment with poor air flow or high outside air temperature, it is difficult to meet the heat dissipation requirements of the power system components by relying solely on blinds for ventilation and heat exchange. Over time, it is easy to cause damage to the power system components in the power supply box. Utility Model Content

[0030] The utility model provides an emergency power supply box structure. Compared with the prior art, ventilation gaps 103 are set on the left and right side walls of the box body 1, exhaust holes 102 are set on the rear side wall of the box body 1, and negative pressure fans 4 are set at positions corresponding to the exhaust holes 102 inside the box body 1. When it is necessary to dissipate heat and cool down the power system components inside the box body 1, the negative pressure fans 4 are started to actively discharge the hot air inside the box body 1 through the exhaust holes 102, so that negative pressure is generated inside the box body 1, and then the air with lower external temperature can continuously enter the box body 1 through the ventilation gaps 103 to form a flowing air flow to dissipate heat and cool down the power system components, thereby improving the heat dissipation efficiency of the power system components.

A plate body 2 is arranged in parallel, and the lower end of the second longitudinal plate 33 is connected to the upper end of the inclined plate 32.

Through the above arrangement, when encountering rainy weather, rainwater will be blocked by the inclined plate 32 and the second longitudinal plate 33 after passing through the ventilation gap 103, and will be discharged from the ventilation gap 103 downward along the inclined plate 32 under the guidance of the inclined plate 32, thereby preventing rainwater from entering the interior of the box body 1 through the ventilation channel 104.
[0032] For further information, see Figures 1 to 3 In order to prevent some foreign matter from entering the box body 1 along with the air flow, a filter screen 5 is provided between the first plate body 2 and the first longitudinal plate 31. In this embodiment, the filter screen 5 completely covers the ventilation gap 103, and the upper end of the filter screen 5 overlaps the first plate body 2 and is fixed to the first plate body 2 by welding, and the lower end of the filter screen 5 overlaps the first longitudinal plate 31 and is fixed to the first longitudinal plate 31 by welding. In this embodiment, the filter screen 5 is provided to filter the air, which can effectively reduce the foreign matter entering the box body 1.
[0033] In some embodiments, see Figures 2 to 5A connecting block 6 is provided between the first plate body 2 and the second longitudinal plate 33, that is, the connecting block 6 is arranged in the ventilation channel 104. In the present embodiment, the connecting block 6 is a rectangular block structure, the length of the connecting block 6 is equivalent to the width of the first block, the connecting block 6 is fixedly connected to the front and rear side walls of the box body 1 by bolts, and the connecting block 6 is also fixedly connected to the first plate body 2 and the second longitudinal plate 33 by bolts.

In the present embodiment, the number of the ventilation holes 61 is multiple, and the multiple ventilation holes 61 are arranged at intervals along the length direction of the connecting block 6. Specifically, the ventilation holes 61 include a first hole body 611 and a second hole body connected from bottom to top. 612, wherein the first hole body 611 is used to connect the ventilation gap 103, and the second hole body 612 is used to connect the storage space 101 in the box body 1. The first hole body 611 and the second hole body 612 are coaxially arranged circular holes. The first hole body 611 and the second hole body 612 have a certain length, and the ratio of the cross-sectional area of the first hole body 611 to the cross-sectional area of the second hole body 612 is not less than 4:1. Through the above arrangement, the cross-sectional area of the first hole body 611 is much larger than the cross-sectional area of the first hole body 611.

[0034] Optional, see Figures 2 to 3 A guide hole 613 is connected between the first hole body 611 and the second hole body 612. In this embodiment, the side wall of the guide hole 613 is inclined from the first hole body 611 side to the second hole body 612 side, so that the cross-sectional area of the guide hole 613 gradually decreases from the first hole body 611 side to the second hole body 612 side. The guide hole 613 reduces the flow resistance of the airflow and increases the airflow rate.
[0035] In some embodiments, see Figure 2A baffle plate 7 is provided inside the box body 1. The baffle plate 7 is connected between the front side wall and the rear side wall of the box body 1 and is correspondingly arranged above the ventilation channel 104. The baffle plate 7 is used to guide the airflow flowing into the box body 1 from the ventilation channel 104 to flow downwardly into the storage space 101. In the present embodiment, the baffle plate 7 includes a first guide plate 71 and a second guide plate 72 connected to each other, wherein a first end of the first guide plate 71 is connected to the first plate body 2, and a second end of the first guide plate 71 is arranged toward the inside of the storage space 101 and tilted upwardly, a first end of the second guide plate 72 is connected to a second end of the first guide plate 71, and a second end of the second guide plate 72 is arranged toward the inside of the storage space 101 and tilted downwardly, so that the first guide plate 71 and the second guide plate 72 form an inverted V-shaped structure, guiding the airflow to turn back upward and then flow downward.
[0036] Furthermore, in order to reduce the resistance of the airflow passing through the deflector 7, an arc plate 73 is connected between the first guide plate 71 and the second guide plate 72. The transition of the arc plate 73 can reduce the resistance of the airflow. Optionally, the first guide plate 71, the second guide plate 72 and the arc plate 73 are integrally processed and formed.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
