[0002] A pole-mounted transformer substation is a power distribution device installed on a utility pole. When large currents flow through the electrical components and wiring inside the substation, heat is inevitably generated. Excessive temperature can negatively impact the performance and lifespan of the insulation materials. Therefore, ventilation holes are provided on the sides of the pole-mounted substation to facilitate heat dissipation. However, since the pole-mounted substation is at a certain height from the ground, during thunderstorms, water spray (such as rain or splashes) can enter the substation through these ventilation holes, affecting the safe operation of the power system.

[0003] Therefore, how to provide a heat dissipation hole protection structure that can prevent water sprayed from all directions from entering the power distribution box while ensuring heat dissipation inside the box is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Another objective of this invention is to provide a benchtop transformer substation that includes the aforementioned heat dissipation hole protection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation hole protection structure is installed on the enclosure of a benchtop transformer substation. It includes a cover shell, one side of which is an open side for sealing connection with the enclosure and covering the heat dissipation holes.

[0012] Preferably, the second side of the highest guide plate facing the opening abuts against the second end of the flange facing the cover shell; the side of the baffle away from the lowest guide plate abuts against the second end of the flange facing the cover shell.

[0018] Preferably, the guide plate has a rotating shaft at both ends along its center line, the two rotating shafts are respectively inserted on both sides of the cover shell along its length, one of the rotating shafts is connected to a driver, and the driver is connected to a host computer via a signal.

[0019] A benchtop transformer substation includes a housing and a heat dissipation hole protection structure as described in any of the above claims.

[0029] 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.

[0030] The core of this utility model is to provide a heat dissipation hole protection structure, which can prevent water sprayed from all directions from entering the power distribution box while taking into account the heat dissipation inside the power distribution box.

[0031] Another core aspect of this utility model is to provide a benchtop transformer substation that includes the aforementioned heat dissipation hole protection structure.

[0032] It should be noted that in this embodiment, the width direction of the cover shell 1 is the front-to-back direction, the length direction of the cover shell 1 is the left-to-right direction, and the height direction of the cover shell 1 is the up-to-down direction. Furthermore, the orientations or positional relationships indicated by "up", "down", "front", "back", "left", and "right" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of describing this application and simplifying the description. They are not intended to 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 this application.

[0033] Please refer to Figure 1 and Figure 3 This application provides a heat dissipation hole protection structure, which is installed on the box of a benchtop transformer substation. It includes a cover shell 1. One side of the cover shell 1 in the width direction is set as an open side for sealing connection with the box body and covering the heat dissipation hole. A plurality of guide plates 4 are provided between the two inner sides in the length direction of the cover shell 1. The plurality of guide plates 4 are spaced apart along the height direction of the cover shell 1 and the first side facing away from the open side is inclined towards the bottom end of the cover shell 1. An exhaust port 5 is provided at the top of the cover shell 1 near the other side in the width direction of the cover shell 1. A first drain port is provided at the bottom end of the cover shell 1.

[0034] Specifically, the rear side of the cover shell 1 is designed as an open side, which is sealed to the enclosure to cover the ventilation holes of the enclosure and to allow communication between the interior of the enclosure and the interior of the cover shell 1. This also prevents water spray from entering the enclosure from the connection between the cover shell 1 and the enclosure. The top of the cover shell 1 has an exhaust port 5, which connects to the interior of the cover shell 1, the open side of the cover shell 1, and the ventilation holes of the enclosure to form a heat dissipation channel. This allows hot air inside the enclosure to be discharged through the heat dissipation channel, thereby achieving heat dissipation inside the distribution box. Furthermore, since the top of the cover shell 1 has an exhaust port 5, external water spray can enter the cover shell 1 through the exhaust port 5. The interior of the cover shell 1 is connected to the interior of the housing through the opening side and heat dissipation holes. To ensure that the water spray entering through the exhaust port 5 cannot enter the interior of the housing, several guide plates 4 are arranged alternately from top to bottom between the left and right inner walls of the cover shell 1. The front side (i.e., the first side facing away from the opening side) of each guide plate 4 slopes downwards towards the bottom of the cover shell 1, making the rear side (i.e., the second side adjacent to the opening side) of each guide plate 4 higher than its... The exhaust port 5 is located on the front side of the top of the cover shell 1, so that the exhaust port 5 is far away from the opening side of the cover shell 1. As a result, most of the sprayed water will be discharged from the first drain port at the bottom along the front side of the inside of the cover shell 1 through the exhaust port 5. Even if some sprayed water splashes towards the rear side (i.e., the opening side) of the inside of the cover shell 1, due to the design of the guide plate 4 which is high at the rear and low at the front, the sprayed water will naturally flow from the rear (higher) side to the front (lower) side along the guide plate 4, and then fall down and be discharged from the first drain port at the bottom, thus ensuring that the sprayed water entering from the exhaust port 5 cannot enter the inside of the box. Moreover, except for the sprayed water at the top, the sprayed water in the other circumferential directions of the cover shell 1 can be blocked by the shell wall of the cover shell 1 to prevent the sprayed water from entering the inside of the box.

[0035] Therefore, the heat dissipation hole protection structure provided in the above embodiments can fully cover the heat dissipation holes of the box while taking into account the heat dissipation inside the distribution box, which can prevent water spray from entering the distribution box, thereby improving the protection level of the box and ensuring the safety of electrical operation.

[0036] It should be noted that in certain severe weather conditions, such as gales, water will be sprayed into the cover 1 from the first drain outlet at the bottom of the cover 1 to further improve the effect of preventing water from entering the distribution box.

[0037] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 and Figure 3 The first side of the lowest guide plate 4 is connected to a baffle 6 extending toward the opening side to form a V-shaped guide plate 9; a second drain port 7 is provided at the bottom of the other side in the width direction of the cover shell 1, and / or, a third drain port 8 is provided at the bottom of both sides in the length direction of the cover shell 1.

[0038] Specifically, the front side of the lowest guide plate 4 is connected to the baffle 6. The side of the baffle 6 away from the guide plate 4 extends backward at an angle to the opening side of the cover shell 1, so that the baffle 6 and the lowest guide plate 4 form a V-shaped guide plate 9. Even though the open end of the V-shaped guide plate 9 faces the rear side of the cover shell 1, the tip of the V-shaped guide plate 9 faces the front side of the cover shell 1.

[0039] In a first specific embodiment, a second drain outlet 7 is provided at the bottom front side of the cover shell 1. Therefore, if water is accidentally sprayed into the cover shell 1 from the first drain outlet at the bottom, the baffle 6 of the V-shaped guide plate 9 can prevent the water from entering the housing. After being blocked by the baffle 6, the water can be discharged from the second drain outlet 7 on the front side. Furthermore, if water is sprayed into the cover shell 1 from the front through the second drain outlet 7, the baffle 6 of the V-shaped guide plate 9 can prevent the water from entering the housing. After being blocked by the baffle 6, the water can be discharged from the first drain outlet below.

[0040] In the second specific embodiment, third drain ports 8 are provided on both the bottom left and bottom right sides of the cover plate. Therefore, if water is accidentally sprayed into the cover shell 1 from the first drain port at the bottom, the baffle 6 of the V-shaped guide plate 9 can prevent the water from entering the housing. After being blocked by the baffle 6, the water can be discharged from the third drain ports 8 on both sides. Furthermore, if water is sprayed into the cover shell 1 from the left or right direction through the third drain ports 8, the baffle 6 of the V-shaped guide plate 9 can prevent the water from entering the housing. After being blocked by the baffle 6, the water can be discharged from the first drain port below.

[0041] In the third specific embodiment, a second drain outlet 7 is provided at the bottom front side of the cover shell 1, and third drain outlets 8 are provided at the bottom left and bottom right sides of the cover plate. Therefore, if water accidentally sprays into the cover shell 1 from the first drain outlet at the bottom, it can be simultaneously discharged from the second drain outlet 7 at the front and from the third drain outlets 8 on the left and right sides after being blocked by the baffle 6 of the V-shaped guide plate 9. This arrangement facilitates the rapid discharge of water accumulated at the bottom of the cover shell 1, preventing excessive water accumulation and entry into the box body.

[0042] Therefore, the V-shaped guide plate 9 provided in the above embodiment can effectively block water sprayed into the first drain port by chance. Once water sprays into the first drain port below, it can be discharged from the front or left and right sides in time, thereby preventing water spray from entering the box through the lower drain port. Moreover, water sprayed in from the front and left and right directions can also be discharged from the lower drain port.

[0043] In summary, the cover 1 of this application covers the heat dissipation holes of the box, which can prevent water sprayed from the top and bottom of the cover 1 from entering the box, as well as prevent water sprayed from the circumference (front, left or right) of the cover 1 from entering the box, thereby effectively preventing water sprayed from all directions from entering the distribution box.

[0044] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The inner circumference of the opening side of the cover shell 1 is provided with a flange 2, and the first end of the flange 2 facing away from the inside of the cover shell 1 is provided with a seal.

[0045] Specifically, flange 2 is welded to the inner circumference of the opening side of the cover shell 1. Flange 2 typically has bolt holes, and bolts pass through the side wall of the enclosure, connecting to the bolt holes on flange 2. The bolts are tightened inside the enclosure to fix flange 2 to the side wall. Flange 2 has a sealing element facing the rear end of the enclosure, located between flange 2 and the enclosure, which seals the cover shell 1 and the enclosure together, preventing external water spray from entering the enclosure through the connection between cover shell 1 and the enclosure. Furthermore, using flange 2 to connect cover shell 1 and the enclosure not only ensures a secure connection but also facilitates later maintenance, replacement, or adjustment of cover shell 1. Additionally, the bolts are tightened from inside the distribution box during installation to prevent unauthorized removal and ensure safety.

[0046] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The first end of the flange 2 is provided with a groove 3 around the flange 2, and the sealing element is a waterproof rubber strip embedded in the groove 3.

[0047] The seal is located in the groove 3 of flange 2. Groove 3 effectively prevents the seal from shifting during use, improves the stability of the seal, and ensures the seal between the cover shell 1 and the housing. Furthermore, the seal uses a waterproof strip, which is waterproof and can be used for extended periods under various climatic conditions.

[0048] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 The second side of the highest guide plate 4 facing the opening abuts against the second end of the flange 2 facing the cover shell 1; the side of the baffle 6 away from the lowest guide plate 4 abuts against the second end of the flange 2 facing the cover shell 1.

[0049] Specifically, as mentioned above, the rear side of each guide plate 4 is higher than its front side, with the rear side of the highest guide plate 4 abutting against the front face of the flange 2. This prevents gap one between the highest guide plate 4 and the flange 2, thus preventing water sprayed through the exhaust port 5 from entering the box through gap one. Furthermore, the baffle 6, located away from the rear side of the lowest guide plate 4, abuts against the front face of the flange 2, preventing gap two between the baffle 6 and the flange 2. This prevents water sprayed through the first drain port / second drain port 7 / third drain port 8 from entering the box through gap two. Therefore, the above arrangement further prevents water sprayed from all directions from entering the distribution box.

[0050] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The exhaust port 5 is elongated and there are two exhaust ports 5, which are spaced apart along the length of the cover shell 1. This arrangement maximizes the size of the exhaust port 5, reduces exhaust resistance, and achieves efficient discharge of hot air.

[0051] Based on the above embodiments, as a further preferred embodiment, the first drain outlet is in the shape of a circular hole, and multiple first drain outlets are arranged in an array. The circular hole shape of the drain outlet can evenly distribute water pressure, avoid localized stress concentration, and ensure long-term stability. Furthermore, the smooth inner wall of the circular hole can reduce dirt accumulation and ensure smooth drainage. The array arrangement of multiple circular hole-shaped drain outlets can increase the drainage area, quickly guide water flow, and reduce the risk of blockage.

[0052] Similarly preferred, such as Figure 2 As shown, the second drain outlet 7 can also be in the shape of a circular hole, and multiple second drain outlets 7 can be arranged in an array; the third drain outlet 8 can also be in the shape of a circular hole, and multiple third drain outlets 8 can be arranged in an array. The second drain outlet 7 and the third drain outlet 8 configured in this way have the same effect as the first drain outlet mentioned above, and will not be described again.

[0053] Based on the above embodiments, as a further preferred embodiment, the center line of the guide plate 4 extends along the length direction of the cover shell 1, and the guide plate 4 can be rotatably disposed between the two inner sides of the cover shell 1 along its center line.

[0054] The air deflector 4 is designed to be rotatable. On the one hand, the angle of the air deflector 4 can be adjusted according to the actual heat dissipation requirements inside the distribution box to achieve dynamic adjustment of wind resistance and ensure good heat dissipation efficiency. On the other hand, the angle of the air deflector 4 can be adjusted according to the actual weather conditions to adjust the air deflector 4 to the optimal waterproof angle and enhance the waterproof effect.

[0055] Based on the above embodiments, as a further preferred embodiment, the guide plate 4 is provided with a rotating shaft at both ends along its center line. The two rotating shafts are respectively inserted on both sides of the cover shell 1 in the length direction. One rotating shaft is connected to the driver, and the driver signal is connected to the host computer.

[0056] It should be noted that the host computer (such as a computer control system) can remotely control the equipment's actions according to a preset program to achieve automated control.

[0057] The guide plate 4 has rotating shafts at both ends along its centerline. The left and right sides of the cover shell 1 have two opposing mounting holes. The two rotating shafts pass through these holes with a clearance fit, allowing the guide plate 4 to rotate around its centerline. One of the rotating shafts is connected to a driver (e.g., a motor). The driver is connected to a host computer via a cable, allowing the user to remotely control the output shaft of the driver to rotate, thus rotating the guide plate 4 to a suitable angle. This achieves automatic adjustment of the guide plate 4's angle while ensuring precise adjustment.

[0058] This utility model also provides a benchtop transformer substation, including a cabinet and the heat dissipation hole protection structure disclosed in the above embodiments. The cabinet has heat dissipation holes on one side, and the cover shell 1 in the heat dissipation hole protection structure covers the heat dissipation holes. The heat dissipation hole protection structure can prevent water spraying from all directions from entering the interior of the transformer substation while ensuring heat dissipation inside the substation. The structure of other parts of this benchtop transformer substation is described in the prior art and will not be repeated here.

[0059] Further optimized, the cabinet has two ventilation holes arranged vertically on one side, namely an upper ventilation hole and a lower ventilation hole, each covered by a cover shell 1. This design provides a natural convection channel. When the temperature inside the cabinet rises, hot air is discharged from the upper cover shell 1. During the airflow inside the cabinet, a negative pressure is formed at the bottom of the cabinet, which can draw in cool air from outside through the lower cover shell 1, thereby achieving a good natural convection cooling effect without the need for an additional fan, reducing energy consumption.

[0060] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The above provides a detailed description of the platform-mounted transformer distribution box and its heat dissipation hole protection structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
