Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a prefabricated prefabricated substation with a vertical ventilation and heat dissipation structure. Background Technology

[0002] Prefabricated substations, also known as prefabricated substations, have a compact structure and are particularly suitable for urban power grid construction and renovation. They are a new type of substation that has developed rapidly after civil engineering substations.

[0003] Prefabricated substations, also known as prefabricated transformer substations, currently employ vertical ventilation for heat dissipation. However, during the heat dissipation process, the airflow blows upwards from the bottom of the prefabricated substation. Therefore, the ventilation method of reserving heat dissipation slots on both sides of the prefabricated substation causes eddies to form when hot air rises to the top of the prefabricated substation and comes into contact with the corners. As a result, some hot air in the prefabricated substation cannot be discharged through the heat dissipation slots in time, affecting the subsequent heat dissipation effect and efficiency inside the prefabricated substation, resulting in poor overall practicality.

[0004] Therefore, we propose a prefabricated box-type transformer with a vertical ventilation and heat dissipation structure to solve the above problems. Utility Model Content

This solves the problem mentioned in the background section: box-type substations, also known as prefabricated substations, currently employ vertical ventilation for heat dissipation. However, during the heat dissipation process, because the airflow blows upwards from the bottom of the prefabricated box-type substation, the ventilation method of reserving heat dissipation slots on both sides of the substation causes hot air to rise to the top and contact the corners, creating vortices. This results in some hot air not being able to be discharged through the heat dissipation slots in time, affecting the subsequent heat dissipation effect and efficiency inside the prefabricated box-type substation, and ultimately leading to poor overall practicality.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an embodiment of the present invention proposes a prefabricated box-type transformer with a vertical ventilation and heat dissipation structure, including a box-type transformer body 1, a box door 2 connected to the front surface of the box-type transformer body 1 by a hinge, and an arc-shaped flow guide seat 3 provided at the top corner of the inner cavity of the box-type transformer body 1. The arc-shaped flow guide seat 3 is symmetrically distributed along the vertical center line of the box-type transformer body 1.

[0029] A fixed base 4 is fixedly provided at the top center of the transformer substation body 1, and a vertical ventilation pipe 5 is fixedly connected to the top center of the fixed base 4. The bottom of the fixed base 4 is connected to the transformer substation body 1. An axial flow fan 6 is fixedly provided in the inner cavity of the fixed base 4. A sealing mechanism is provided in the inner cavity of the vertical ventilation pipe 5. A top cover 11 is fixedly connected to the top of the fixed base 4, and a diversion seat 12 is fixedly provided at the bottom center of the top cover 11. The contact surface between the diversion seat 12 and the top cover 11 is arc-shaped. A guide groove 13 is provided on one side of the bottom of the top cover 11. The guide groove 13 is equidistantly distributed along the center point of the top cover 11, and the guide groove 13 and the top cover 11 form an integrated structure.

[0030] During use, the hot air generated by the operation of electrical components inside the transformer substation body 1 flows towards the top of the body. The hot air then flows along the arc-shaped guide seat 3. The inner arc surface of the guide seat 3 facilitates effective airflow guidance, preventing eddies from forming when the hot air contacts the corners of the transformer substation body 1, which would affect subsequent heat dissipation. Simultaneously, the axial flow fan 6 generates suction, drawing the hot air from the transformer substation body 1 into the fixed seat 4. The connection between the fixed seat 4 and the vertical ventilation pipe 5 allows the hot air to be discharged through the vertical ventilation pipe 5. The air discharged through the vertical ventilation pipe 5 is then diverted by the diversion seat 12. The diverted hot air then flows along the diversion grooves on the surface of the diversion seat 12 and into the guide groove 13, thereby improving the overall heat dissipation effect and enhancing overall practicality.

[0031] like Figure 3 As shown, in some embodiments, the sealing mechanism includes a fixed retaining ring 7, a return spring 8, a sealing plug 9, and a through hole 10. The fixed retaining ring 7 is fixedly disposed on the inner side of the top end of the vertical ventilation pipe 5, and the bottom of the fixed retaining ring 7 is fixedly connected to the return spring 8. A hole is opened at the center of the fixed retaining ring 7. The other end of the return spring 8 is fixedly connected to the sealing plug 9. The outer diameter of the sealing plug 9 is adapted to the inner diameter of the through groove opened on the inner side of one end of the vertical ventilation pipe 5. A through hole 10 is opened on the side wall of the sealing plug 9.

[0032] In use, when the axial flow fan 6 blows air into the inside of the vertical ventilation duct 5, the air pressure will push the sealing plug 9. At this time, the sealing plug 9 moves longitudinally inside the vertical ventilation duct 5, causing one end of the sealing plug 9 to separate from the inside of one end of the vertical ventilation duct 5. As the sealing plug 9 splits, the through hole 10 opened on the side wall of the sealing plug 9 can be used to facilitate the subsequent connection of the entire vertical ventilation duct 5. Then, the hot air drawn by the axial flow fan 6 will be discharged through the vertical ventilation duct 5. It is worth noting that when the sealing plug 9 moves longitudinally, it will cause the return spring 8 to deform, thereby generating a reverse force. Then, when the pressure applied to the sealing plug 9 disappears, the reverse force generated by the deformation of the return spring 8 will assist the sealing plug 9 to reset. When the sealing plug 9 resets and seals the vertical ventilation duct 5, it can not only prevent outside air from entering the inside of the transformer body 1 through the vertical ventilation duct 5, but also effectively prevent dust.

[0033] like Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, a grid groove 14 is provided on one side of the bottom of the transformer body 1. The grid groove 14 is symmetrically distributed along the vertical center line of the transformer body 1. A drying plate 15 is installed on the inner side of the bottom of the transformer body 1. A heat dissipation fan 16 is distributed above the drying plate 15. A grid mesh plate 17 is distributed above the heat dissipation fan 16. Multiple holes are equidistantly opened on the surface of the grid mesh plate 17.

[0034] In use, the cooling fan 16 draws air into the bottom inner side of the transformer substation body 1 through the grille slots 14 opened on both sides of the bottom. The air then passes through the drying plate 15 to dry the air. After drying, the air is blown into the inner side of the transformer substation body 1 through the grille plate 17 by the cooling fan 16, which facilitates the subsequent use of the air blown into the transformer substation body 1 to dissipate heat from the inner side of the transformer substation body 1.

[0035] like Figure 2 and Figure 5 As shown, in some embodiments, the arc-shaped flow guide seat 3 is symmetrically distributed along the vertical center line of the transformer body 1, and one end surface of the arc-shaped flow guide seat 3 is arc-shaped.

[0036] When in use, since one end of the arc-shaped guide seat 3 has an arc shape, when hot air flows along the arc surface of the arc-shaped guide seat 3, it can effectively prevent the generation of eddies and improve the flow efficiency of hot air.

[0037] like Figure 3 As shown, in some embodiments, the sealing plug 9 is slidably connected to the vertical ventilation pipe 5 by the return spring 8, and the through holes 10 are symmetrically distributed along the vertical center line of the sealing plug 9.

[0038] When in use, when the sealing plug 9 moves longitudinally, it will compress the return spring 8, thereby deforming the return spring 8 to generate a reverse force, which facilitates the subsequent rebound of the auxiliary sealing plug 9. The through hole 10 facilitates the subsequent flow of hot air.

[0039] like Figure 3 and Figure 4 As shown, in some embodiments, the flow divider 12 is generally conical, and the bottom outer ring surface of the flow divider 12 has multiple flow divider grooves distributed at equal intervals along the center point;

[0040] When in use, since the overall shape of the diverter seat 12 is conical and the bottom outer ring surface of the diverter seat 12 is provided with diverter grooves at equal intervals, the diverter seat 12 can be used to facilitate the effective diversion of the exhaust hot air.

[0041] In summary, the cooling fan 16 draws air into the bottom inner side of the transformer substation body 1. The air then passes through the drying plate 15 and is blown into the inner side of the transformer substation body 1 by the cooling fan 16. As the cool air enters, the hot air flows to the top of the transformer substation body 1 and circulates along the arc-shaped guide seat 3. At this point, the inner arc surface of the arc-shaped guide seat 3 can be used to facilitate the effective guidance of hot air, preventing the formation of vortices when hot air comes into contact with the corner of the transformer body 1, which would affect the subsequent normal heat dissipation. Simultaneously, the axial flow fan 6 generates suction, which can draw the hot air from the transformer body 1 into the fixed seat 4. When the axial flow fan 6 blows air into the inner side of the vertical ventilation duct 5, the air pressure will push the sealing plug 9. The sealing plug 9 will then move longitudinally within the vertical ventilation duct 5, causing one end of the sealing plug 9 to separate from the inner side of the vertical ventilation duct 5. With the diversion of the sealing plug 9, the through hole 10 on the side wall of the sealing plug 9 facilitates the subsequent connection of the entire vertical ventilation duct 5. The hot air drawn by the axial flow fan 6 will then... The vertical ventilation duct 5 is discharged. It is worth noting that when the sealing plug 9 moves longitudinally, it will cause the return spring 8 to deform, thereby generating a reverse force. Then, when the pressure applied to the sealing plug 9 disappears, the reverse force generated by the deformation of the return spring 8 will assist the sealing plug 9 in resetting. When the sealing plug 9 resets and seals the vertical ventilation duct 5, it can not only prevent outside air from entering the inside of the transformer body 1 through the vertical ventilation duct 5, but also effectively prevent dust. The air discharged through the vertical ventilation duct 5 will be diverted by the diversion seat 12. The hot air after diversion will be diverted along the diversion groove opened on the surface of the diversion seat 12 and enter the guide groove 13 along the flow of the diversion groove, thereby improving the heat dissipation effect of the entire structure.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
