Description

Technical Field

[0001] This utility model relates to the field of ventilation structure technology, specifically a ventilation structure for a box-type substation. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are typically built on a foundation on the ground, with a protective enclosure erected on top. Inside the enclosure are multiple transformers and other electronic components. Through the cooperation of these components, the transformer operation is completed. Due to their compact structure, ventilation and heat dissipation are particularly important, especially in harsh weather conditions. If heat dissipation and cooling cannot be achieved quickly, the normal operation of the equipment cannot be guaranteed, and the safety and stability of the power grid may even be compromised, resulting in significant economic losses.

[0003] A search revealed Chinese patent CN217720440U, which discloses a ventilation structure and a prefabricated substation for a box-type substation, belonging to the field of electrical equipment. The structure includes a box body with a concrete base fixedly cast on its lower surface. A door is slidably connected to the side of the box body via a rotating shaft. A box top is welded to the upper surface of the box body. A mounting frame is fixedly cast on the upper surface of the concrete base. This ventilation structure and prefabricated substation for a box-type substation, by fixing the box body and mounting frame to the upper surface of the concrete base, can securely fix the box body and mounting frame. The design of the concrete base isolates the mounting frame from contact with the box body, preventing electrical leakage from causing the box body to become electrified and posing a safety hazard. By tightening bolts on the inner wall of the box, the fixing blocks are brought into close contact with the inner wall, facilitating the disassembly, replacement, and cleaning of the ventilation windows. The design of the rain shield prevents rainwater from entering the box body through the air outlet, thus preventing damage to the electrical equipment.

[0004] However, the above design still has shortcomings. In the above design, the heat dissipation window is directly fixed to the inner wall of the box and is fixed with traditional bolts. This means that when the operators need to remove the heat dissipation window for cleaning and maintenance, they must open the box door of the box substation and disassemble it from the inside of the box, which is quite inconvenient.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a ventilation structure for a prefabricated substation to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ventilation structure for a box-type substation, applied to a substation enclosure, wherein support blocks are fixedly connected to the four corners of the bottom of the substation enclosure, mounting grooves are provided on both outer walls of the substation enclosure, heat dissipation vents are provided on the inner side of the mounting grooves and are connected to the interior of the substation enclosure, a second magnetic plate is fixedly installed inside the mounting groove, a first magnetic plate is magnetically connected to the two second magnetic plates on the side away from each other, a heat dissipation window is fixedly connected to the two first magnetic plates on the side away from each other, a protective frame is provided on the top of the heat dissipation window, and a cooling fan is installed inside the heat dissipation window.

[0012] As a further embodiment of this utility model: connecting rods are fixedly connected to both sides of the top of the substation box, and a baffle plate is fixedly connected to the top of the connecting rods.

[0014] (1) Through the structural design of heat dissipation window, first magnetic plate, heat dissipation fan, heat dissipation port, mounting groove and second magnetic plate, the heat dissipation window can be easily disassembled and assembled, the operation is simple and the disassembly and assembly efficiency is high. At the same time, it can blow the high heat inside the box to the outside of the box, and the outside air enters the box through the heat dissipation hole, thereby achieving the purpose of ventilation and heat dissipation. This solves the problem that the heat dissipation window is directly fixed to the inner wall of the box and is fixed with traditional bolts. This means that when the operators need to remove the heat dissipation window for cleaning and maintenance, they must open the box door of the box substation and disassemble it from the inside of the box, which is quite inconvenient.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figure 1-8 An embodiment of this utility model provides a ventilation structure for a box-type substation, applied to a substation box 5. Connecting rods 1 are fixedly connected to both sides of the top of the substation box 5, and a baffle plate 4 is fixedly connected to the top of the connecting rods 1. Support blocks 3 are fixedly connected to the four corners of the bottom of the substation box 5. Mounting grooves 14 are opened on the outer walls of both sides of the substation box 5. Heat dissipation vents 13 are provided on the inner side of the mounting grooves 14, and the heat dissipation vents 13 are connected to the interior of the substation box 5. A second magnetic plate 20 is fixedly installed inside the mounting grooves 14. A first magnetic plate 11 is magnetically connected to the side of the two second magnetic plates 20 that are far apart from each other. A heat dissipation window 7 is fixedly connected to the side of the two first magnetic plates 11 that are far apart from each other. A protective frame 2 is provided on the top of the heat dissipation window 7, and a heat dissipation fan 12 is installed inside the heat dissipation window 7.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, when it is necessary to disassemble the heat dissipation window 7, move the heat dissipation window 7 along the outside to separate the first magnetic plate 11 from the second magnetic plate 20, thereby completing the disassembly of the heat dissipation window 7. Similarly, the heat dissipation window 7 can be installed. The operation is simple and the disassembly and assembly efficiency is high. At the same time, the wind force generated by the rotation of the cooling fan 12 can blow the high heat inside the box to the outside of the box, and the outside air enters the box through the heat dissipation hole 15, thereby achieving the purpose of ventilation and heat dissipation. This solves the problem that the heat dissipation window 7 is directly fixed to the inner wall of the box and is fixed with traditional bolts. This means that when the operator needs to remove the heat dissipation window 7 for cleaning and maintenance, the box door of the box substation must be opened and disassembled from the inside of the box, which is quite inconvenient.

[0032] A threaded groove 19 is provided at the frame opening of the heat dissipation window 7. A first threaded cover 8 is threadedly connected to the inner wall of the threaded groove 19. A first mounting hole 9 is provided through the surface of the first threaded cover 8. A first filter screen 10 is fixedly installed inside the first mounting hole 9. A substation box door 6 is rotatably provided on the front end face of the substation box 5. A plurality of heat dissipation holes 15 are provided through the surface of the substation box door 6. A second threaded cover 16 is threadedly connected to the inner wall of the heat dissipation hole 15. A second mounting hole 17 is provided through the surface of the second threaded cover 16. A second filter screen 18 is fixedly installed inside the second mounting hole 17.

[0033] Specifically, such as Figure 3 , Figure 6 and Figure 7 As shown, when it is necessary to disassemble and clean the first filter screen 10 and the second filter screen 18, the first threaded cover 8 can be rotated to disengage from the threaded groove 19, and the second threaded cover 16 can be rotated to disengage from the heat dissipation hole 15, thereby completing the disassembly of the first filter screen 10 and the second filter screen 18. Similarly, after the first filter screen 10 and the second filter screen 18 are cleaned, they can be easily installed. By making it easy to disassemble, clean and install the first filter screen 10 and the second filter screen 18, the filtration effect can be effectively guaranteed.

[0034] Working principle: In this application, when the heat dissipation window 7 needs to be disassembled, the heat dissipation window 7 is moved along the outer side, so that the first magnetic plate 11 and the second magnetic plate 20 are separated, thereby completing the disassembly of the heat dissipation window 7. Similarly, the heat dissipation window 7 can be installed. The operation is simple and the disassembly and assembly efficiency is high. At the same time, the wind force generated by the rotation of the cooling fan 12 can blow the high heat inside the box to the outside of the box, and the outside air enters the box through the heat dissipation hole 15, thereby achieving the purpose of ventilation and heat dissipation. Secondly, when the first filter screen 10 and the second filter screen 18 need to be disassembled and cleaned, the first threaded cover 8 can be rotated to disengage from the threaded groove 19, and the second threaded cover 16 can be rotated to disengage from the heat dissipation hole 15, thereby completing the disassembly of the first filter screen 10 and the second filter screen 18. Similarly, after the first filter screen 10 and the second filter screen 18 are cleaned, it is easy to install the first filter screen 10 and the second filter screen 18. By making it easy to disassemble, clean and install the first filter screen 10 and the second filter screen 18, the filtration effect can be effectively guaranteed.
