Description

Technical Field

[0001] The present application relates to the technical field of energy-saving control of switching power supplies, and in particular to a low-carbon temperature-controlled power supply cabinet. Background Art

[0002] Large-scale 5G deployment is currently underway. Because 5G offers higher frequency bands and greater bandwidth, sites need to be densely populated. However, the power consumption of a single 5G site is 2.5 to 3.5 times that of a single 4G site. As the number of devices increases, construction faces challenges: limited space within traditional base stations, making it difficult to add new equipment; limited switching power supplies and power distribution capacity within base stations, making expansion difficult; and persistent conflicts between operators' base station construction, property management, and various interference factors, making site construction difficult.

[0003] The ambient temperature has a significant impact on the charge and discharge characteristics of the battery pack in the power cabinet. The optimal operating temperature is 25°C ± 5°C, so measures must be taken to regulate the temperature of the battery pack.

[0004] Currently, power cabinets use air conditioners to control the temperature of equipment, which results in high power consumption, high power usage effectiveness (PUE), and severe energy loss. Utility Model Content

[0058] Reference Figure 1 and Figure 2As a low-carbon temperature-controlled power supply cabinet provided in this embodiment, the cabinet includes a cabinet body 1, wherein the cabinet body 1 is provided with a power supply compartment 11 for accommodating a power distribution unit, and a battery compartment 12 for accommodating a battery 16, and further includes:

[0059] There is at least one external switching power supply module 13 installed outside the cabinet 1;

[0060] There is at least one in-cabinet switching power supply module 14 installed inside the cabinet 1 and located around the power supply compartment 11;

[0061] The battery 16 is located in the battery compartment 12 and is electrically connected to the external switching power supply module 13 and the internal switching power supply module 14 .

[0062] In the embodiment of the present application, the power supply compartment 11 and the battery compartment 12 are arranged vertically within the cabinet 1, with the power supply compartment 11 located directly above the battery compartment 12. However, this layout is not fixed. Alternatively, the battery compartment 12 may be placed above the power supply compartment 11, or the two may be arranged horizontally, with the power supply compartment 11 located to one side of the battery compartment 12. This design diversity ensures the adaptability and practicality of the device in different scenarios.

[0063] In an embodiment of the present application, when the external ambient temperature is high, a staff member or system can selectively activate the external switching power module 13 while simultaneously deactivating the internal switching power module 14, thereby reducing the temperature around the battery 16 and preventing overheating from affecting the performance of the battery 16. Conversely, when the external ambient temperature is low, a staff member or system can selectively activate the internal switching power module 14 while simultaneously reducing the power of the external switching power module 13 to zero. This utilizes the heat naturally dissipated by the internal switching power module 14 during operation to effectively raise the temperature around the battery 16 and ensure that the battery operates within an appropriate temperature range. Furthermore, a staff member or system can simultaneously activate the internal switching power module 14 and the external switching power module 13 and flexibly adjust the power ratio between the two to achieve different temperatures at which the internal switching power module 14 dissipates heat, thereby providing different temperature levels for the battery 16. This structure not only avoids the need to install additional air conditioning equipment but also achieves energy conservation and emission reduction, thus meeting environmental protection requirements.

[0064] Reference Figure 3 Furthermore, this application does not impose any specific restrictions on the installation method between the external switching power supply module 13 and the cabinet body 1, and provides a variety of flexible fixing solutions. Welding can be used to achieve a stable connection, while bolting can also be used. This design flexibility is intended to meet the needs of different application scenarios, taking into account the convenience of installation and maintenance.

[0065] Reference Figure 3、 Figure 4 and Figure 5 As the optimal solution in the embodiment of the present application, the external switch power supply module 13 is connected to the outer wall of the cabinet 1 through the connection component 2. The connection component 2 includes:

[0066] The fixing frame 21 is fixedly connected to the outer wall of the cabinet 1. The fixing frame 21 has a slot 211 formed in a direction from top to bottom. The slot 211 passes through the top of the fixing frame 21 but does not pass through the bottom of the fixing frame 21.

[0067] The connecting frame 22 is fixedly connected to the back of the external switch power supply module 13 , and the connecting frame is provided with a plug-in board 221 that is plugged and adapted to the slot 211 .

[0068] In the embodiment of the present application, the slot 211 and the plug board 221 are arranged at a mutually matching angle, so that when the staff installs the switch power supply module 13 outside the cabinet, they can easily insert the plug board 221 into the slot 211, thereby facilitating the installation work of the staff.

[0069] The connection between the fixing frame 21 and the cabinet body 1 can be welding or bolting, which is not limited to this; the same is true for the connection between the connecting frame 22 and the external switching power supply module 13. Of course, in order to facilitate the disassembly of the fixing frame 21 and the connecting frame 22, the bolting method is preferably used.

[0070] To improve the stability of the external switch power module 13 after installation, two slots 211 are provided. The two slots 211 are respectively located on both sides of the fixing frame 21 facing away from the cabinet body 1 , and two plug-in boards 221 are also provided on the corresponding connecting frame 22 .

[0071] Furthermore, a top plate 222 is fixed to the top of the connecting frame 22 . When the plug-in board 221 is fully inserted into the slot 211 , the lower surface of the top plate 222 is completely in contact with the top of the fixing frame 21 .

[0072] When installing the external switching power supply module 13, the operator simply aligns the connecting bracket 22 with the cabinet 1, ensuring that the connecting bracket 22 is directly above the fixing bracket 21. The operator then slowly lowers the external switching power supply module 13 until the plug-in board 221 precisely fits into the slot 211. This easily completes the connection between the external switching power supply module 13 and the cabinet 1. This simple and quick installation process greatly improves work efficiency. When the external switching power supply module 13 needs to be removed, the operator simply moves the external switching power supply module 13 upward to easily disconnect it, providing the same convenience for the operator's removal work.

[0073] When the external switching power supply module 13 is securely mounted on the side wall of the cabinet 1, the two plug-in boards 221 fit tightly against the bottom wall of the slot 211, and the top plate 222 abuts against the top wall of the fixing frame 21, effectively increasing the contact area between the connecting frame 22 and the fixing frame 21, avoiding stress concentration, significantly improving the structural stability between the two, and ensuring the reliability of equipment operation. In the embodiment of the present application, in order to ensure the power supply of the power cabinet, the number of external switching power supply modules 13 is set to three, and the three external switching power supply modules 13 are respectively arranged on both sides of the cabinet 1 and the back of the cabinet 1. Of course, the number and installation position of the external switching power supply modules 13 are not restrictive.

[0074] Reference 1 and Figure 3 In an embodiment of the present application, the outer wall of the cabinet 1 is provided with a cavity 15 concave inwardly toward the battery compartment 12 around the power supply compartment 11. The number of cavities 15 matches the number of external switching power supply modules 13, ensuring that each external switching power supply module 13 is located in a cavity 15. The top of the cavity 15 passes through the top of the cabinet 1, providing a smooth installation path for the external switching power supply module 13. When the external switching power supply module 13 is installed in the cavity 15, its outer surface and the edge of the cavity 15 do not protrude outward, which means that the depth of the cavity 15 is not less than the thickness of the external switching power supply module 13. As for the structure of the cavity 15, the embodiment of the present application does not impose any special restrictions, as long as the external switching power supply module 13 can be completely placed inside itself. Preferably, the left wall, right wall, and lower wall of the cavity are all set to be inclined surfaces to facilitate heat dissipation of the switching power supply module and improve the heat dissipation effect of the external switching power supply module.

[0075] In the present application, the depth of the cavity 15 is greater than the thickness of the external switching power supply module 13. The outer surface of the external switching power supply module 13 is flush with the outer wall of the cabinet 1 at the cavity 15 through the connecting component 2, forming a neat and unified appearance, and there is sufficient distance between the external switching power supply module 13 and the outer wall of the cabinet 1 at the cavity 15 to ensure the heat dissipation requirements of the external switching power supply module 13 itself.

[0076] Reference Figure 3 and Figure 6 In the embodiment of the present application, a heat dissipation vent 111 is provided on the side wall of the cabinet 1 at the power supply compartment 11, and a heat dissipation device 112 is provided in the power supply compartment 11 for discharging hot air in the power supply compartment 11. The heat dissipation device 112 includes:

[0077] The cooling fan 1121 has its blowing side facing the cooling vent 111 and is used to discharge the hot air in the power supply compartment 11 from the cooling vent 111;

[0078] The fixed cover 1122 is installed at the heat dissipation port 111 and is set as an opening on the side facing the heat dissipation port 111 . The heat dissipation fan 1121 is located in the fixed cover 1122 , and the air suction side of the heat dissipation fan 1121 extends from the interior of the fixed cover 1122 .

[0079] The continuous blowing of the cooling fan 1121 effectively and rapidly expel the hot air inside the power supply compartment 11 through the heat dissipation vents 111, thereby significantly cooling the interior of the power supply compartment 11. The fixed cover 1122 seals the heat dissipation vents 111, preventing hot air that is not promptly exhausted from the heat dissipation vents 111 from flowing back into the power supply compartment 11, ensuring efficient heat dissipation and significantly improving the cooling effect on the power supply compartment 11.

[0080] In the embodiment of the present application, a detachable connection is employed between the cooling fan 1121 and the fixed cover 1122. Similarly, a detachable connection is employed between the fixed cover 1122 and the cabinet 1, ensuring the independence and interchangeability of each component. In the event of a malfunction in the cooling fan 1121, a worker can easily remove the fixed cover 1122 and the cooling fan 1121 from the side wall of the cabinet 1, and then remove the cooling fan 1121 from the fixed cover 1122 alone, facilitating replacement or repair. The detachable connection greatly facilitates equipment maintenance and improves maintenance efficiency.

[0081] Reference Figure 2 and Figure 7 , the power cabinet in the embodiment of the present application also includes:

[0082] The base 3 is installed at the bottom of the cabinet 1. The bottom of the cabinet 1 is provided with an air outlet 31 for penetrating the base 3. The side wall of the base 3 is provided with an exhaust port 32.

[0083] The exhaust fan 4 is installed in the base 3 and is located directly below the air outlet 31 . The air outlet side of the exhaust fan 4 faces the air outlet 32 and is used to discharge the hot air in the cabinet 1 from the air outlet 32 .

[0084] In the embodiment of the present application, when the temperature in the battery compartment 12 reaches a threshold value that is too high and needs to be further cooled, the exhaust fan 4 will be started. The exhaust fan 4 draws the hot air in the battery compartment 12 from the air outlet 31, guides it into the interior of the base 3, and then discharges it from the exhaust port 32. This process effectively achieves further cooling of the battery compartment 12 and ensures the stable operation of the device. It is worth noting that the exhaust port 32 and the battery compartment 12 are not directly connected. This design has significant advantages: when the external ambient temperature is low and the battery compartment 12 needs to be heated, cold air is not easy to directly enter the battery compartment 12, thereby effectively maintaining the temperature of the battery compartment 12, achieving a good thermal insulation effect, ensuring that the battery operates within an appropriate temperature range, and improving the reliability and efficiency of the device.

[0085] In an embodiment of the present application, in order to further improve the exhaust efficiency of the exhaust fan 4 for the hot air in the battery compartment 12, a deflector 5 is provided in the battery compartment 12 in the vertical direction. The cross-section of the deflector 5 is designed to be L-shaped, which fits neatly at the inner corner of the cabinet 1 and is firmly connected to the inner wall of the cabinet 1 by welding, ensuring the stability and reliability of the structure. A heat conduction channel 51 is formed between the deflector 5 and the inner wall of the cabinet 1. The bottom of the deflector 5 fits tightly against the inner bottom wall of the battery compartment 12, while its top maintains a certain gap with the inner top wall of the battery compartment 12. This design enables the heat conduction channel 51 to be directly connected to the air outlet 31, effectively guiding the flow of hot air and improving the heat exhaust efficiency of the exhaust fan 4. Of course, the cross-sectional structure of the deflector 5 is not limited to L-shaped, but can also be "U"-shaped, "Cao"-shaped, etc., to meet the needs of different scenarios and improve the adaptability and flexibility of the equipment.

[0086] In the embodiment of the present application, based on the natural principle that cold air flows downward and hot air flows upward, the hot air within the battery compartment 12 naturally gathers at the top of the battery compartment 12. When the exhaust fan 4 is activated, the hot air is drawn in from the top of the air deflector 5, then guided to the air outlet 31 through the heat conduction channel 51, and finally exhausted from the air outlet 32. This process fully utilizes the structural advantages of the air deflector 5, effectively improving the cooling efficiency of the exhaust fan 4 on the battery compartment 12 and ensuring precise control of the internal temperature of the battery compartment 12.

[0087] In an embodiment of the present application, in order to further improve the exhaust efficiency of the exhaust fan 4 for hot air, a windshield 41 is provided at the air outlet 31. The top of the windshield 41 is tightly connected and fixed to the bottom of the air deflector 5, ensuring the stability and reliability of the structure. A through-hole 411 is provided between the top of the windshield 41 and the side wall of the bottom of the air deflector 5. This design allows the heat conduction channel 51 to be directly connected to the interior of the windshield 41, ensuring smooth flow of hot air. The bottom of the windshield 41 is connected and fixed to the exhaust fan 4, and the air suction side of the exhaust fan 4 is installed inside the windshield 41, while the air discharge side is installed outside the windshield 41. Through the provision of the windshield 41, the hot air transported by the heat conduction channel 51 can directly reach the air suction side of the exhaust fan 4, effectively preventing the hot air from diffusing in the base 3, further improving the exhaust efficiency of the exhaust fan 4 for hot air, and ensuring stable operation and efficient heat dissipation of the equipment.

[0088] There are no strict restrictions on the connection between the windshield 41 and the air guide 5, or between the windshield 41 and the exhaust fan 4. Various methods can be used, such as gluing, welding, and bolting, but bolting is preferred. Bolting not only ensures structural stability and reliability but also facilitates repair or replacement of the exhaust fan 4, improving the equipment's ease of maintenance and flexibility.

[0089] In the embodiment of the present application, a shutter 42 is provided between the exhaust fan 4 and the exhaust port 32. The shutter 42 further enhances the temperature control capability of the device. The shutter 42 can be controlled electrically or non-electrically. We have not set strict restrictions on this in order to adapt to the needs of different application scenarios. In the present application, a shutter 42 of a non-electric structure is selected. When the exhaust fan 4 blows air toward the shutter 42, the shutter 42 automatically opens due to the wind force, ensuring that the hot air is discharged smoothly. When the exhaust fan 4 stops blowing, the shutter 42 can automatically close, further preventing cold air from entering the cabinet 1 from the exhaust port 32.

[0090] Reference Figure 2In the embodiment of the present application, the cabinet 1 is provided with an air inlet 33 on the bottom wall of the battery compartment 12 that is connected to the base 3, and an air inlet 34 is provided on the side wall of the base 3. This design ensures smooth air circulation. When the exhaust fan 4 is started, hot air is discharged from the air outlet 32, and the battery compartment 12 is in a negative pressure environment. The cold air from the outside is first sucked into the base 3 through the air inlet 34, and then sucked into the battery compartment 12 through the air inlet 33. Thus, the effect of ventilation in the battery compartment 12 is achieved. It is worth noting that during the air intake process, the cold air first enters the base 3 through the air inlet 34, and then enters the battery compartment 12 through the air inlet 33, rather than a straight-through structure. This design has significant advantages: when the external ambient temperature is low and the battery compartment 12 needs to be heated, the exhaust fan 4 is not started at this time, so there will be no negative pressure environment in the battery compartment 12, and cold air will not be easily sucked into the battery compartment 12, thereby effectively maintaining the temperature of the battery compartment 12, achieving a good thermal insulation effect, ensuring that the battery operates within an appropriate temperature range, and improving the reliability and efficiency of the equipment.

[0091] In order to ensure the cleanliness of the interior of the cabinet 1, a dustproof device 6 is provided at the air inlet 33 or the air intake 34. Of course, a dustproof device 6 can also be provided at both the air inlet 33 and the air intake 34 to achieve double protection. The dustproof device 6 filters the air entering the cabinet 1, effectively preventing the invasion of dust and impurities, ensuring the cleanliness of the interior of the cabinet 1 and the stable operation of the equipment. There are no special restrictions on the specific structure of the dustproof device 6 to meet the needs of different application scenarios. In this application, dustproof cotton is used, which has good filtering effect and durability, can effectively block dust and impurities, and ensure the long-term cleanliness of the interior of the power cabinet.

[0092] In the embodiments of the present application, to further isolate the temperature inside the battery compartment 12 from the effects of external temperatures, an insulation layer is attached to the inner wall of the battery compartment 12. Made of thermal insulation cotton, the insulation layer offers excellent thermal insulation properties, effectively reducing the impact of external temperature fluctuations on the internal temperature of the battery compartment 12 and ensuring stable operation of the battery within a suitable temperature range. The provision of the insulation layer not only improves the thermal insulation performance of the device but also reduces its energy consumption, improving energy efficiency and ensuring long-term stable operation of the device.

[0093] Reference Figure 2A placement plate 121 for placing the batteries 16 and a bracket 122 for fixing the placement plate 121 are provided in the battery compartment 12, ensuring the stable placement and efficient heat dissipation of the batteries 16. In the embodiment of the present application, four brackets 122 are provided, and the four brackets 122 are all arranged in the vertical direction and located at the four corners of the placement plate 121, ensuring the stability and balance of the placement plate 121. The two ends of the bracket 122 are fixedly connected to the top wall and the bottom wall of the battery compartment 12 respectively, forming a stable support structure, which improves the stability and reliability of the equipment. The placement plates 121 can be set in different quantities according to the number of batteries 16 actually placed in the battery compartment 12 as needed to meet the needs of different application scenarios. In the present application, taking the setting of two placement plates 121 as an example, the two placement plates 121 are parallel to each other, ensuring the uniform distribution of the batteries 16 and the heat dissipation effect.

[0094] It is worth noting that to improve the heat dissipation of the battery 16, the placement plate 121 is provided with a plurality of ventilation holes 1211. The ventilation holes 1211 not only help dissipate heat from the bottom of the battery 16 but also ensure ventilation within the battery compartment 12. The provision of ventilation holes 1211 improves the heat dissipation efficiency of the battery compartment 12, reduces the temperature within the battery compartment 12, and increases the service life of the power cabinet.

[0095] Reference Figure 1 , reference Figure 8 and Figure 9 In the embodiment of the present application, the low-carbon temperature-controlled power supply cabinet further includes: a protective brim 7, buckled on the top of the cabinet body 1;

[0096] A cabinet door 17 is provided at the front side of the cabinet body 1 and is used to close the interior of the cabinet body 1. A safety lock 171 is provided between the cabinet door and the cabinet body for fixing.

[0097] The first matching structure is provided on a side of the protective cap brim 7 away from the front of the cabinet 1 after the protective cap brim 7 is installed on the top of the cabinet 1;

[0098] The second matching structure is provided on a side of the cabinet body 1 away from the cabinet door 17, and is fixedly matched with the first matching structure when the protective visor 7 is installed on the top of the cabinet body 1, and is hidden between the cabinet body 1 and the protective visor 7 together with the first matching structure;

[0099] A fixing plate 73 is fixedly connected to the side of the protective brim 7 close to the front of the cabinet 1. After the protective brim 7 is installed on the top of the cabinet 1, the fixing plate 73 is located between the cabinet door 17 and the cabinet 1;

[0100] The fixing structure is provided between the cabinet 1 and the fixing plate 73 , and is used to connect and fix the fixing plate 73 to the cabinet 1 .

[0101] In this embodiment, there are no specific restrictions on the structure of the security lock 171. The security lock 171 can have various forms, including a traditional mechanical lock to ensure stability and reliability, an advanced Bluetooth lock to achieve remote control and intelligent management, or a high-precision fingerprint lock to provide personalized security protection to meet the security needs of different scenarios.

[0102] In an embodiment of the present application, when installing the protective brim 7, first, through the precise docking of the first matching structure and the second matching structure, a firm connection between one side of the protective brim 7 and the back of the cabinet 1 is achieved, laying the foundation for the protective structure. Subsequently, the fixing plate 73 is tightly connected to the front side of the cabinet 1 using the fixing structure, thereby completing the fixation of the other side of the protective brim 7 to the front side of the cabinet 1, forming a stable structure. When the cabinet door 17 is closed, the fixing structure and the fixing plate 73 are cleverly hidden between the cabinet 1 and the cabinet door 17, ensuring that the installation structure of the protective brim 7 is completely not exposed, avoiding unnecessary safety hazards. The subtlety of this structure is that if the protective brim 7 needs to be removed, the cabinet door 17 must first be opened through the safety lock 171. This mechanism greatly improves the safety level of the power cabinet, effectively prevents the risk of theft or malicious damage to the unit module on the top of the cabinet 1, and provides a solid guarantee for equipment safety.

[0103] In an embodiment of the present application, in order to significantly improve the convenience of installation between the protective visor 7 and the cabinet body 1, the first matching structure and the second matching structure are made into a clip-on structure. This clip-on structure not only supports repeatable installation and disassembly, but also does not cause any damage to the parts during operation, ensuring reliability and durability for long-term use. More importantly, the design of the clip-on structure fully considers simplicity and cost-effectiveness, making the connection operation simple and convenient, greatly improving work efficiency, and bringing great convenience to the staff. The clip-on structure has various forms. It can be a slot-type clip-on structure, which achieves a stable connection through a precise slot design; it can also be a hook-type clip-on structure, which uses the flexibility of the hook to ensure quick installation and disassembly; it can also be a claw-type clip-on structure, which provides additional safety through the gripping force of the claw. No special restrictions are imposed on the specific form of the clip-on structure.

[0104] In the embodiment of the present application, the snap-fit structure between the protective brim 7 and the cabinet 1 is further optimized. Specifically, the first matching structure and the second matching structure can be easily snapped together by horizontally moving the protective brim 7 toward the rear side of the cabinet 1. This means that after the staff places the protective brim 7 on the top of the cabinet 1, they only need to simply push the protective brim 7 backward in the horizontal direction, and the first matching structure and the second matching structure can automatically complete precise docking to form a stable snap-fit state. The above structure not only improves the operating efficiency, but also ensures the stability of the connection between the protective brim 7 and the cabinet 1, providing great convenience for the staff when installing the protective brim 7, significantly improving the work efficiency and installation experience.

[0105] In a specific implementation of the embodiment of the present application, it is intended to achieve a stable connection between the protective brim 7 and the cabinet 1, while ensuring the simplicity and efficiency of the installation process. Specifically, the second matching structure is a hole structure or a clip 72; and the first matching structure includes a clip plate 71, which is fixedly connected to the bottom of the protective brim 7. The clip plate 71 can be coplanar with the side wall of the protective brim 7, or it can be located inside the protective brim 7 and perpendicular to the side wall of the protective brim 7. When the clip plate 71 is arranged inside the protective brim 7, the second matching structure is located on the top wall of the cabinet 1; when the clip plate 71 is arranged coplanar with the side wall of the protective brim 7, the second matching structure is arranged on the side wall of the top of the cabinet 1.

[0106] The clamping plate 71 is provided with a clamping member 72 or a hole structure that is adapted to be clamped with the second matching structure. Specifically, when the second matching structure adopts a hole structure, the clamping member 72 is provided on the clamping plate 71. The clamping member 72 and the hole structure are engaged to achieve a firm connection between the protective brim 7 and the cabinet 1. Conversely, when the second matching structure is a clamping member 72, the clamping plate 71 is provided with a hole structure. The precise docking of the clamping member 72 and the hole structure also ensures the stability and reliability of the connection. During the actual installation process, after the protective brim 7 is buckled and placed on the top of the cabinet 1, the clamping member 72 will be accurately inserted into the hole structure. Then, the protective brim 7 can be easily clamped and fixed by simply pushing it horizontally.

[0107] Furthermore, in the embodiment of the present application, a better connection effect and easier operation are achieved. Specifically, the clamping plate 71 is provided with a hole structure that penetrates the clamping plate 71. In other words, the second matching structure is the clamping member 72, which complements the hole structure on the clamping plate 71 and together constitutes a clamping structure. The clamping plate 71 is provided inside the protective visor 7, and the second matching structure, the clamping member 72, is provided on the top wall of the cabinet 1. This layout not only optimizes space utilization, but also ensures a smooth and stable clamping process.

[0108] Specifically, the clamping member 72 includes a connecting portion 721 and a clamping portion 722. One end of the connecting portion 721 is fixedly connected to the top wall of the cabinet 1 (if the clamping member 72 is provided on the clamping plate 71, one end of the connecting portion 721 will be connected to the side wall of the clamping plate 71 facing the cabinet 1), and the other end forms an integrated fixed structure with the clamping portion 722, thereby ensuring the stability and reliability of the connection. It is worth noting that the cross-sectional dimension of the clamping portion 722 must be larger than the cross-sectional dimension of the connecting portion 721. In the embodiment of the present application, the cross-sections of the clamping portion 722 and the connecting portion 721 are both circular. There is no special restriction on the connection method between the connecting portion 721 and the top wall of the cabinet 1. It can be welding, gluing, or threaded connection.

[0109] Specifically, the hole structure is arranged on the clamping plate 71, and the hole structure is a chain hole 711. The chain hole 711 includes a first hole 7111 and a second hole 7112. It is worth noting that the first hole 7111 is located on the side of the second hole 7112 away from the front of the cabinet 1 and the two are connected to each other. The size of the first hole 7111 needs to be no less than the size of the clamping part 722, and the size of the second hole 7112 needs to be smaller than the size of the clamping part 722 but not smaller than the size of the connecting part 721; the size of the connection between the first hole 7111 and the second hole 7112 is no less than the size of the connecting part 721.

[0110] When the staff buckles the protective brim 7 on the top of the cabinet 1, the second matching structure is located at the first hole 7111, the connecting part 721 is located in the first hole 7111, and the clamping part 722 passes through the top of the first hole 7111. After the staff pushes the protective brim 7, the connecting part 721 and the clamping part 722 are located in the second hole 7112, the connecting part 721 passes through the second hole 7112, and the clamping part 722 is located above the second hole 7112. Since the size of the clamping part 722 is larger than the size of the second hole 7112, the clamping part 722 cannot pass through the second hole 7112, thereby realizing the clamping connection between the second matching structure and the first matching structure, thereby fixing the protective brim 7 on the top of the cabinet 1.

[0111] In the embodiment of the present application, after the first matching structure and the second matching structure are completely engaged, the fixing plate 73 and the cabinet 1 are fixed by the fixing structure.

[0112] In the preferred embodiment of this application, the fixing structure utilizes a bolted connection. Specifically, through-holes are provided in the fixing plate 73, while matching threaded holes are provided in the top of the cabinet 1. During assembly, bolts pass through the through-holes in the fixing plate 73 and precisely engage with the threaded holes in the top of the cabinet 1, ensuring a secure connection between the fixing plate 73 and the cabinet 1. This design not only simplifies installation but also ensures a reliable and stable connection.

[0113] Reference Figure 10 In another preferred embodiment of the present application, the fixing structure adopts a snap-in structure, and the specific implementation method is not limited. One feasible implementation method is as follows: a rotatable snap-in block is installed on the side wall of the top of the cabinet 1 facing the fixed plate 73, and the snap-in block forms a rotational connection with the side wall of the cabinet 1. A through hole matching the snap-in block is designed on the fixed plate 73. After the snap-in block passes through the through hole, the snap-in block is rotated to form a snap-in state with the through hole, thereby achieving a stable connection between the fixed plate 73 and the cabinet 1. The shape of the snap-in block is diverse and can be rectangular, triangular or special-shaped to meet the needs of different application scenarios. This snap-in structure not only facilitates quick assembly, but also ensures the firmness and convenience of the connection.

[0114] Reference Figure 11 In this embodiment of the present application, the top of the external switching power supply module 13 is provided with a terminal block 131. Terminal block 131 can be precisely inserted into the protective cap visor 7. This design not only effectively prevents the risk of malicious insertion and removal of terminal block 131, but also significantly improves the safety protection performance of terminal block 131. The shielding effect of the protective cap visor 7 provides additional protection for terminal block 131, preventing damage caused by external factors and ensuring the stable operation and safety performance of the power supply cabinet in outdoor environments.

[0115] In an embodiment of the present application, to enhance the waterproof performance and stability of the external switching power module 13, a waterproof housing 8 and a pressure plate 9 are provided on the top of the external switching power module 13. The waterproof housing 8 is cleverly positioned between the pressure plate 9 and the external switching power module 13, forming a multi-layer waterproof barrier that significantly enhances the module's waterproofing. Bolts penetrate one side of the pressure plate 9 and the waterproof housing 8, respectively, and are threadedly connected to the top of the cabinet 1, ensuring the secure fixation of the entire structure. The other end of the pressure plate 9 presses tightly against the bottom of the plug-in terminal, providing not only stability for the waterproof housing 8 but also a reliable fixation for the terminal 131, effectively preventing any loosening during use and ensuring the stable operation and safety performance of the power module in various environments. This design not only enhances the waterproofing effect but also strengthens the stability and reliability of the structure, providing a solid guarantee for the long-term stable operation of the power module. In addition, after installation, the bottom of the protective visor 7 is flush with the waterproof housing 8, preventing rainwater from flowing back to the top of the cabinet 1 during rain.
