[0002] An energy storage prefabricated substation is a type of power distribution device that houses high-voltage switchgear, distribution transformers, low-voltage power distribution equipment, and battery packs within a steel structure enclosure. Because the substation generates a significant amount of heat during operation, a forced ventilation structure is required to ensure the stable operation of the various power distribution devices within the enclosure. In existing technologies, the forced ventilation structure typically consists of a fan mounted on the top cover, air inlets on the side walls, and air outlets on the top cover. The fan draws outside air into the enclosure through the inlets and exhausts it through the outlets, creating airflow and carrying away heat. However, in this structure, dust from the outside can directly enter the enclosure through the air inlets, leading to dust accumulation over time and affecting the normal operation of the power distribution equipment.
[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] As shown in the figure, an energy storage box-type substation includes a box body 1. Transformers, power distribution equipment, and battery packs are arranged inside the box body 1. A top cover 2 is provided on the top of the box body 1, and a fan 3 is installed inside the top cover 2. An air outlet 21 is provided on the top cover 2. A first air inlet 11 is provided on the side plate of the box body 1. A dustproof box 4 is located on one side of the first air inlet 11 and is attached to the inner wall of the box body 1. Vertical partitions 41 are provided inside the dustproof box 4. The partition 41 divides the internal space of the dustproof box 4 into a first air guide cavity 42 and a second air guide cavity 43. A second air inlet 44 is provided on the lower part of the side plate of the dustproof box 4 near the inner wall of the box body 1 so that the first air guide cavity 42 is connected to the first air inlet 11. A third air inlet 45 is provided on the upper part of the partition 41 so that the first air guide cavity 42 and the second air guide cavity 43 are connected. A fourth air inlet 46 is provided on the lower part of the side plate of the dustproof box 4 away from the inner wall of the box body 1 so that the second air guide cavity 43 is connected to the interior of the box body 1.
[0025] In the above structure, the operation of the fan 3 creates a negative pressure state inside the housing 1. Air outside the housing 1, under the pressure difference between the inside and outside of the housing 1, enters the dustproof housing 4 through the first air inlet 11 and the second air inlet 44. The air entering the dustproof housing rises upwards in the first air guide cavity 42. During this upward rise, dust particles carried in the air are released from the air by gravity and fall, reducing the dust content in the air that rises to the third air inlet 45 and enters the second air guide cavity 43. The air entering the second air guide cavity 43 then enters the housing 1 through the fourth air inlet 46, and flows towards the fan 3 within the housing 1. The upward movement of the fan allows the heat generated inside the enclosure 1 to be carried away and then into the top cover 2 via the fan 3. Finally, the heat generated inside the enclosure 1 is discharged from the air outlet 21 on the top cover 2, ensuring the normal operation of the power distribution equipment inside the enclosure 1. During the process of discharging heat from the enclosure 1, the air outside the enclosure 1 is protected by the dustproof box 4 before entering the enclosure 1, which reduces the amount of dust carried in the air and thus reduces the amount of dust entering the enclosure 1. This provides a certain degree of dust protection and reduces the accumulation of dust inside the enclosure 1, ensuring the normal operation of the power distribution equipment inside the enclosure 1. Furthermore, the dust protection achieved by the dustproof box 4 is low-cost, maintenance-free, and easy to use.
[0026] Furthermore, based on the above structure, a first dust baffle plate 47 and a second dust baffle plate 48 are fixedly connected to the inner wall of the first air guide cavity 42 and are staggered above the second air inlet 44. The ends of the first dust baffle plate 47 and the second dust baffle plate 48 are inclined downward. As the air outside the box 1 enters the first air guide cavity 42 through the first air inlet 11 and the second air inlet 44 and rises upward, the dust carried in the air hits the first dust baffle plate 47 and the second dust baffle plate 48 and falls under the action of gravity, further reducing the dust that passes through the third air inlet 45 with the air, thereby achieving a better dust prevention effect.
[0027] In addition, based on the above structure, a dust discharge port 12 is provided on the side plate of the box 1, which is located below the first air inlet 11 and communicates with the first air inlet cavity. Dust entering the first air guide cavity 42 with the air falls to the bottom of the first air guide cavity 42 under the action of gravity and is discharged from the box 1 in time through the dust discharge port 12, preventing dust from accumulating in the dustproof box 4.
[0028] In addition, based on the above structure, a first dust discharge guide plate 49 located below the second air inlet 44 is fixedly connected to the inner wall of the first air guide cavity 42. The end of the first dust discharge guide plate 49 is inclined downward and extends out of the dust discharge port 12. A windproof plate 13 located on one side of the dust discharge port 1 is fixedly connected to the outer wall of the side plate of the box body 1. The dust falling to the bottom of the first air guide cavity 42 falls onto the first dust discharge guide plate 49 and is discharged from the box body 1 along the first dust discharge guide plate 49. The first dust discharge guide plate 49 ensures that the falling dust can be smoothly discharged from the box body 1. The windproof plate 13 located on one side of the dust discharge port 12 blocks the crosswind outside the box body 1, ensuring that the dust will not be affected by the crosswind and will not retreat back into the box body 1 when it is discharged from the box body 1, thus ensuring that the dust can be smoothly discharged from the box body 1.
[0029] In addition, based on the above structure, the upper end of the first dust discharge guide plate 49 is fixedly connected to an insect-proof plate 50 located between the first air inlet 11 and the dust discharge outlet 12. The insect-proof plate 50 has several dust discharge holes. Falling dust falls through the dust discharge outlet 12 on the insect-proof plate 50 onto the first dust discharge guide plate 49 and is discharged from the box 1. The insect-proof plate 50 can prevent small animals such as insects and rodents on the ground from entering the dust box 4 through the lower dust discharge outlet 12, thus playing the role of preventing insects and rodents.
[0030] Furthermore, based on the above structure, several air guide plates 51 located on one side of the fourth air inlet 46 are fixedly connected to the outer wall of the side panel of the dustproof box 4 away from the inner wall of the box body 1. The ends of the air guide plates 51 are inclined upwards. After passing through the fourth air inlet 46, the air in the second air guide cavity 43 is guided by the air guide plates 51 and flows upwards in the box body 1. The air guide plates 51 guide the air flow and ensure that the air rises upwards, carries away the heat and is discharged from the box body 1, thereby improving the heat dissipation efficiency.
[0031] Furthermore, based on the above structure, a number of mounting feet are formed on the outer wall of the dustproof box 4. The mounting feet are connected to the box body 1 by bolts to realize the fixed connection between the dustproof box 4 and the box body 1. The dustproof box 4, which is installed by mounting feet and bolts, is easy to disassemble and assemble, which facilitates the overall processing of the energy storage box substation. Moreover, it does not require excessive processing of the existing energy storage substation. A better dustproof effect can be achieved by installing the dustproof box 4.
[0032] In addition, based on the above structure, two second-row dust guide plates 22 are fixedly installed inside the top cover, respectively inclined on both sides of the fan 3. The higher end of the second-row dust guide plate 22 is close to the fan 3, and the air outlet 21 is located on the lower end side of the second-row dust guide plate 22. After the air entering the box 1 through the dustproof box 4 carries heat and is discharged into the top cover 2 by the fan 3, a small amount of dust that may still be carried in the air falls onto the second-row dust guide plate 22 and slides down along the second-row dust guide plate 22 and is discharged from the top cover 2 through the air outlet 21, reducing the accumulation of dust in the top cover 2 and achieving a better dustproof effect.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
