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] Currently, large-scale 5G construction is underway. Because 5G has a higher frequency band and a larger bandwidth, more dense sites are needed. 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, the construction process faces the problem that the space of traditional base stations is limited and there is no space to add new equipment; the switching power supply and power distribution capacity in the base station is limited, making it difficult to expand the capacity; the "entanglement" between the operator's base station construction and property and various interference factors continues to exist, making it difficult to build sites.

[0003] The ambient temperature has a great influence on the charging and discharging characteristics of the battery pack in the power cabinet. The optimal operating temperature is 25℃±5℃, so measures should be taken to adjust the temperature of the battery pack.

[0004] At present, the method adopted by the power cabinet is to directly open an air outlet on one side of the battery and install an exhaust fan at the air outlet, so that the heat around the battery is discharged through the exhaust fan.

[0005] Although this method can effectively and quickly discharge the heat generated by the battery to achieve a cooling effect when the battery needs to be cooled, when the outside temperature is low, the exhaust fan stops rotating and cold air will enter directly from the air outlet, causing the battery to have a defect of too low an operating temperature. Utility Model Content

[0006] The purpose of the present application is to provide a low-carbon temperature-controlled power supply cabinet, aiming to solve the problem in the related art that cold air easily enters directly from the air outlet, causing the battery operating temperature to be too low.

[0007] Additional aspects and advantages of the present application will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the present application.

[0008] According to the present application, a low-carbon temperature-controlled power supply cabinet is provided, comprising a cabinet body, wherein a battery compartment for storing batteries is arranged in the cabinet body, and batteries are placed in the battery compartment, and further comprising:

[0009] There is at least one switch power supply module in the cabinet, which is installed inside the cabinet and located around the battery;

[0010] A base is installed at the bottom of the cabinet, the bottom of the cabinet is provided with an air outlet for penetrating the base, and a side wall of the base is provided with an exhaust port;

[0011] An exhaust fan is installed in the base and is located directly below the air outlet. The exhaust fan has an air outlet side facing the air outlet and is used to exhaust the hot air in the cabinet from the air outlet.

[0012] In an exemplary embodiment of the present application, an air duct is provided in the battery compartment for guiding the hot air to the exhaust fan. The air duct is vertically arranged directly above the air outlet. A heat conduction channel is formed in the air duct, and the heat conduction channel is connected to the air outlet. A gap is left between the top of the air duct and the inner top wall of the battery compartment.

[0013] In an exemplary embodiment of the present application, a wind shield is arranged in the air outlet, the top of the wind shield is fixedly connected to the air guide cover, and the heat conduction channel is connected to the interior of the wind shield; the bottom of the wind shield is fixedly connected to the exhaust fan, and the air suction side of the exhaust fan is located in the wind shield.

[0014] In an exemplary embodiment of the present application, the exhaust fan and the wind shield are detachably connected.

[0015] In an exemplary embodiment of the present application, a shutter is provided between the exhaust fan and the exhaust port.

[0016] In an exemplary embodiment of the present application, it is characterized in that an air inlet for communicating with the base is opened at the bottom of the cabinet, and an air inlet is opened through the side wall of the base.

[0017] In an exemplary embodiment of the present application, a dustproof device for preventing dust from entering is provided at the air inlet and / or the air intake.

[0018] In an exemplary embodiment of the present application, a thermal insulation layer is attached to the interior of the battery compartment.

[0019] In an exemplary embodiment of the present application, it further includes an external switch power supply module, which is arranged outside the cabinet.

[0021] The exemplary embodiments of the present application may have some or all of the following beneficial effects:

[0022] In a low-carbon temperature-controlled power supply cabinet provided in an example implementation of the present application, a base is added at the bottom of the cabinet and an exhaust fan is arranged in the base. When hot air needs to be exhausted, the exhaust fan is started, and the exhaust fan can draw the hot air from the outlet into the base, and then exhaust it from the exhaust port. When the outside temperature is low, since the exhaust port and the outlet are not directly connected, cold air is not easy to flow into the battery compartment, so that the operating temperature of the battery is not easy to be too low.

DETAILED DESCRIPTION

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed descriptions will be omitted. In addition, the drawings are only schematic illustrations of the present application and are not necessarily drawn to scale.

[0039] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the diagram to another component, these terms are used in this specification only for convenience, such as according to the direction of the examples in the drawings. It is understood that if the device of the diagram is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0040] The terms "a", "an", "the" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" are used merely as labels and are not intended to limit the quantity of their objects.

[0041] Reference Figure 1 and Figure 2 As a low-carbon temperature-controlled power supply cabinet provided in this embodiment, the cabinet includes a cabinet body 1, wherein a power supply compartment 11 for placing a power distribution unit and a battery compartment 12 for placing a storage battery 16 are provided in the cabinet body 1, and further includes:

[0042] There is at least one external switch power supply module 13 installed outside the cabinet 1;

[0043] There is at least one switch power supply module 14 in the cabinet, which is installed inside the cabinet 1 and located around the power supply compartment 11;

[0044] The storage battery 16 is located in the battery compartment 12 and is electrically connected to the external switch power module 13 and the internal switch power module 14 .

[0045] In the embodiment of the present application, the power supply compartment 11 and the battery compartment 12 are arranged in a vertical direction inside the cabinet 1, and the power supply compartment 11 is located directly above the battery compartment 12, but this layout is not fixed. The battery compartment 12 can also be placed above the power supply compartment 11, or the two can be arranged in a horizontal direction, with the power supply compartment 11 located on one side of the battery compartment 12. This design diversity ensures the adaptability and practicality of the device in different scenarios.

[0046] In the embodiment of the present application, when the external environment temperature is high, the staff or system can selectively start the switch power module 13 outside the cabinet and turn off the switch power module 14 inside the cabinet, so as to reduce the temperature around the battery 16 and avoid overheating affecting the performance of the battery 16. On the contrary, when the external environment temperature is low, the staff or system can selectively start the switch power module 14 inside the cabinet and reduce the power of the switch power module 13 outside the cabinet to zero, and use the heat naturally emitted when the switch power module 14 inside the cabinet works to effectively increase the temperature of the environment around the battery 16 and ensure that the battery operates within a suitable temperature range. In addition, the staff or system can also start the switch power module 14 inside the cabinet and the switch power module 13 outside the cabinet at the same time, and flexibly adjust the power ratio of the two to achieve the temperature at which the switch power module 14 inside the cabinet emits different heat, thereby providing different levels of temperature environment for the battery 16. This structure not only avoids the need to install additional air-conditioning equipment, but also realizes the environmental protection needs of energy saving and emission reduction, and meets environmental protection needs.

[0047] Reference Figure 3 Furthermore, the present application does not specifically limit the installation method between the external switch power supply module 13 and the cabinet 1, and provides a variety of flexible fixing schemes. Welding can be used to achieve a stable connection, or bolt connection can be selected. The flexibility of this design is intended to meet the needs of different application scenarios, taking into account the convenience of installation and maintenance.

[0048] Reference Figure 3 , Figure 4 and Figure 5 As the optimal solution in the embodiment of the present application, the switch power supply module 13 outside the cabinet is connected to the outer wall of the cabinet 1 through the connection component 2. The connection component 2 includes:

[0049] A fixing frame 21 is fixedly connected to the outer wall of the cabinet 1, and a slot 211 is provided on the fixing frame 21 from top to bottom, and the slot 211 passes through the top of the fixing frame 21 but does not pass through the bottom of the fixing frame 21;

[0050] The connecting frame 22 is fixedly connected to the back of the switch power supply module 13 outside the cabinet, and the connecting piece is provided with a plug-in board 221 which is plugged and matched with the slot 211.

[0051] In the embodiment of the present application, the slot 211 and the plug board 221 are provided with a matching angle, so that when the staff installs the switch power supply module 13 outside the cabinet, the plug board 221 can be easily inserted into the slot 211, thereby facilitating the installation work of the staff.

[0052] The connection between the fixing frame 21 and the cabinet 1 can be welding or bolting, which is not limited; the same is true for the connection between the connecting frame 22 and the switch power supply module 13 outside the cabinet. Of course, in order to facilitate the disassembly of the fixing frame 21 and the connecting frame 22, bolting is preferably used.

[0053] 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 away from the cabinet body 1 , and two plug-in boards 221 are also provided on the corresponding connecting frame 22 .

[0054] Furthermore, a top plate 222 is fixedly provided on 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 fitted with the top of the fixing frame 21 .

[0055] When installing the external switch power module 13, the staff only needs to align the connection frame 22 with the cabinet 1, ensure that the connection frame 22 is located directly above the fixing frame 21, and then slowly lower the external switch power module 13 until the plug board 221 is accurately embedded in the slot 211, and the connection between the external switch power module 13 and the cabinet 1 can be easily completed. This installation process is simple and fast, greatly improving work efficiency. When it is necessary to disassemble the external switch power module 13, it is only necessary to move the external switch power module 13 upward to easily release the connection, which provides the same convenience for the staff's disassembly work.

[0056] When the external switch power supply module 13 is firmly installed 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, which effectively increases the contact area between the connecting frame 22 and the fixing frame 21, avoids stress concentration, significantly improves the structural stability between the two, and ensures 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 switch power supply modules 13 is set to three, and the three external switch 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 switch power supply modules 13 are not restrictive.

[0057] Reference 1 and Figure 3 In the embodiment of the present application, the outer wall of the cabinet 1 is provided with a cavity 15 concave in the direction of the battery compartment 12 around the power compartment 11, and the number of the cavities 15 matches the number of the external switch power modules 13, ensuring that each external switch power 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 switch power module 13. When the external switch power 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 switch power module 13. As for the structure of the cavity 15, the embodiment of the present application does not make any special restrictions, as long as the external switch power module 13 can be completely placed in itself. Preferably, the left wall, right wall and lower wall of the cavity are all set to be inclined surfaces to facilitate the heat dissipation of the switch power module and improve the heat dissipation effect of the external switch power module.

[0058] 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 a sufficient distance is left 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.

[0059] Reference Figure 3 and Figure 6In the embodiment of the present application, the cabinet 1 has a heat dissipation port 111 on the side wall of the power supply compartment 11, and a heat dissipation device 112 for discharging hot air in the power supply compartment 11 is provided in the power supply compartment 11. The heat dissipation device 112 includes:

[0060] The cooling fan 1121 has a 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;

[0061] 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 out from the inside of the fixed cover 1122 .

[0062] The continuous blowing of the heat dissipation fan 1121 can effectively and quickly discharge the hot air in the power supply compartment 11 from the heat dissipation port 111, thereby achieving a significant cooling effect on the inside of the power supply compartment 11. The fixed cover 1122 forms a seal around the heat dissipation port 111 to prevent the hot air that is not discharged from the heat dissipation port 111 from flowing back into the power supply compartment 11, thereby ensuring the high efficiency of the heat dissipation process and significantly improving the cooling effect on the power supply compartment 11.

[0063] In the embodiment of the present application, the heat dissipation fan 1121 and the fixed cover 1122 are detachably connected. Similarly, the fixed cover 1122 and the cabinet 1 are also detachably connected, ensuring the independence and interchangeability of each component. When the heat dissipation fan 1121 fails, the staff can easily remove the fixed cover 1122 and the heat dissipation fan 1121 from the side wall of the cabinet 1, and then remove the heat dissipation fan 1121 from the fixed cover 1122 alone, which is convenient for replacement or repair. The detachable connection greatly facilitates the maintenance of the equipment and improves the maintenance efficiency.

[0064] Reference Figure 2 and Figure 7 , the power cabinet in the embodiment of the present application also includes:

[0065] 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 air outlet 32.

[0066] 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 exhaust the hot air in the cabinet 1 from the air outlet 32 ​​.

[0067] 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, and the exhaust fan 4 will draw the hot air in the battery compartment 12 from the air outlet 31, introduce it into the base 3, and then discharge 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 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, 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 insulation effect, ensuring that the battery operates within a suitable temperature range, and improving the reliability and efficiency of the equipment.

[0068] In the 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 along the vertical direction. The cross section of the deflector 5 is designed to be L-shaped, which is cleverly fitted 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 is tightly fitted to the inner bottom wall of the battery compartment 12, and the top of the deflector 5 maintains a certain gap with the inner top wall of the battery compartment 12. This design makes the heat conduction channel 51 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 structure of the cross section of the deflector 5 is not limited to L-shaped, but can also be "U"-shaped, "concave"-shaped, etc., to meet the needs of different scenarios and improve the adaptability and flexibility of the equipment.

[0069] 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 in the battery compartment 12 naturally gathers at the top of the battery compartment 12. When the exhaust fan 4 is started, the hot air is drawn in from the top of the air guide cover 5, and then the hot air is guided to the air outlet 31 through the heat conduction channel 51, and finally the hot air is discharged from the air outlet 32. This process fully utilizes the structural advantages of the air guide cover 5, effectively improves the cooling efficiency of the exhaust fan 4 on the battery compartment 12, and ensures the precise control of the internal temperature of the battery compartment 12.

[0070] In the embodiment of the present application, in order to further improve the exhaust efficiency of the exhaust fan 4 for hot air, a wind shield 41 is specially provided at the air outlet 31. The top of the wind shield 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 wind shield 41 and the side wall at the bottom of the air deflector 5. This design allows the heat conduction channel 51 to be directly connected to the inside of the wind shield 41, ensuring smooth flow of hot air. The bottom of the wind shield 41 is connected and fixed to the exhaust fan 4, and the air suction side of the exhaust fan 4 is installed in the wind shield 41, while the air outlet side is installed outside the wind shield 41. Through the setting of the wind shield 41, the hot air transported by the heat conduction channel 51 can directly reach the side of the exhaust fan 4 where the exhaust fan 4 sucks air, effectively avoiding the diffusion of hot air in the base 3, further improving the exhaust efficiency of the exhaust fan 4 for hot air, and ensuring the stable operation and efficient heat dissipation of the equipment.

[0071] There are no strict restrictions on the connection between the wind shield 41 and the air guide 5, and the connection between the wind shield 41 and the exhaust fan 4. The connection can be made by gluing, welding, bolting, etc., but bolting is preferred. The bolting method not only ensures the stability and reliability of the structure, but also facilitates the maintenance or replacement of the exhaust fan 4, thereby improving the maintenance convenience and flexibility of the equipment.

[0072] In an embodiment of the present application, a shutter 42 is provided between the exhaust fan 4 and the exhaust port 32, and the shutter 42 further enhances the temperature control capability of the device. The shutter 42 can be controlled by electric or non-electric means, and we have not set strict restrictions on this in order to meet 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 is automatically opened by the wind force to ensure smooth discharge of hot air. When the exhaust fan 4 stops blowing air, the shutter 42 can be automatically closed, further preventing cold air from entering the cabinet 1 from the exhaust port 32.

[0073] Reference Figure 2In the embodiment of the present application, the cabinet 1 is provided with an air inlet 33 which is connected with the base 3 at the bottom wall of the battery compartment 12, and an air inlet 34 is provided through 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.

[0074] For the cleanliness of the interior of the cabinet 1, a dustproof device 6 is provided at the air inlet 33 or the air inlet 34. Of course, a dustproof device 6 can also be provided at both the air inlet 33 and the air inlet 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. No special restrictions are set for 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.

[0075] In the embodiment of the present application, in order to further isolate the influence of the external temperature on the temperature inside the battery compartment 12, a thermal insulation layer is pasted on the inner wall of the battery compartment 12. The thermal insulation layer is made of thermal insulation cotton, which has good thermal insulation performance, can effectively reduce the influence of external temperature fluctuations on the internal temperature of the battery compartment 12, and ensure that the battery works stably within a suitable temperature range. The setting of the thermal insulation layer not only improves the thermal insulation performance of the equipment, but also reduces the energy consumption of the equipment, improves the energy utilization efficiency, and provides a guarantee for the long-term stable operation of the equipment.

[0076] Reference Figure 2A placement plate 121 for placing the battery 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 battery 16. In the embodiment of the present application, four brackets 122 are provided, and the four brackets 122 are 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, to form a stable support structure, thereby improving the stability and reliability of the equipment. The placement plates 121 can be set in different numbers 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 and heat dissipation effect of the batteries 16.

[0077] It is worth noting that in order to improve the heat dissipation effect of the battery 16, a plurality of air holes 1211 are provided through the placement plate 121, which not only help to dissipate heat from the bottom of the battery 16, but also ensure the ventilation effect in the battery compartment 12. The provision of the air holes 1211 improves the heat dissipation efficiency of the battery compartment 12, reduces the temperature in the battery compartment 12, and increases the service life of the power cabinet.

[0078] Reference Figure 1 , reference Figure 8 and Fig. 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;

[0079] 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 1 for fixing.

[0080] The first matching structure is arranged on a side away from the front of the cabinet 1 after the protective cap brim 7 is installed on the top of the cabinet 1;

[0081] The second matching structure is arranged on a side of the cabinet 1 away from the cabinet door 17, and forms a fixed match with the first matching structure when the protective cap brim 7 is installed on the top of the cabinet 1, and is hidden between the cabinet 1 and the protective cap brim 7 together with the first matching structure;

[0082] A fixing plate 73 is fixedly connected to a 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;

[0083] The fixing structure is disposed between the cabinet 1 and the fixing plate 73 , and is used to connect and fix the fixing plate 73 to the cabinet 1 .

[0084] In this embodiment, no specific restrictions are imposed on the structure of the security lock 171. The security lock 171 can be in various forms, and can use a traditional mechanical lock to ensure its stability and reliability; it can also use an advanced Bluetooth lock to achieve remote control and intelligent management; it can also be a high-precision fingerprint lock to provide personalized security protection to meet the security needs in different scenarios.

[0085] In the 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 stable 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 by 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 to form 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 by 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 top unit module of the cabinet 1, and provides a solid guarantee for equipment safety.

[0086] In an embodiment of the present application, in order to significantly improve the convenience of installation between the protective brim 7 and the cabinet 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 the reliability and durability of long-term use. More importantly, the design of the clip-on structure fully considers the simplicity and cost-effectiveness, making the connection operation simple and convenient, greatly improving the work efficiency, and bringing great convenience to the staff. The clip-on structure has various forms, which can be a slot-type clip-on structure, which realizes 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 protection through the gripping force of the claw. No special restrictions are imposed on the specific form of the clip-on structure.

[0087] 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 snap-fitted by horizontally moving the protective brim 7 to 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. Through the above structure, not only the operating efficiency is improved, but also the stability of the connection between the protective brim 7 and the cabinet 1 is ensured, which provides great convenience for the staff when installing the protective brim 7, and significantly improves the work efficiency and installation experience.

[0088] 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 at the top of the cabinet 1.

[0089] The clamping plate 71 is provided with a clamping part 72 or a hole structure that is clamped and adapted to the second matching structure. Specifically, when the second matching structure adopts a hole structure, the clamping part 72 is provided on the clamping plate 71, and the clamping cooperation between the clamping part 72 and the hole structure is realized to achieve a firm connection between the protective brim 7 and the cabinet 1; conversely, when the second matching structure is a clamping part 72, a hole structure is provided on the clamping plate 71, and the stability and reliability of the connection are also ensured by the precise docking of the clamping part 72 and the hole structure. In the actual installation process, when the protective brim 7 is buckled and placed on the top of the cabinet 1, the clamping part 72 will be accurately inserted into the hole structure, and then the protective brim 7 can be easily clamped and fixed by simply pushing it horizontally.

[0090] Furthermore, in the embodiment of the present application, a better connection effect and convenient operation are achieved. Specifically, a hole structure is provided on the clamping plate 71, and the hole structure runs through the clamping plate 71, that is, the second matching structure is a clamping member 72, which complements the hole structure on the clamping plate 71 and together constitutes a clamping structure. The clamping plate 71 is arranged inside the protective visor 7, and the second matching structure, that is, the clamping member 72, is arranged on the top wall of the cabinet 1. This layout not only optimizes space utilization, but also ensures the smoothness and stability of the clamping process.

[0091] 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-sectional dimensions 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, which can be welding, gluing, or threaded connection.

[0092] Specifically, the hole structure is arranged on the clamping plate 71, and the hole structure is a serial hole 711, and the serial 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 portion 722, and the size of the second hole 7112 needs to be smaller than the size of the clamping portion 722 but not smaller than the size of the connecting portion 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 portion 721.

[0093] 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 snap-on 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 snap-on part 722 are located in the second hole 7112, the connecting part 721 passes through the second hole 7112, and the snap-on part 722 is located above the second hole 7112. Since the size of the snap-on part 722 is larger than the size of the second hole 7112, the snap-on part 722 cannot pass through the second hole 7112, thereby realizing the snap-on connection between the second matching structure and the first matching structure, thereby fixing the protective brim 7 on the top of the cabinet 1.

[0094] In the embodiment of the present application, after the first matching structure and the second matching structure are snap-fitted, the fixing plate 73 and the cabinet 1 are fixed by a fixing structure.

[0095] In the preferred embodiment of the present application, the fixing structure adopts a bolt connection method. Specifically, a through hole is designed on the fixing plate 73, and a matching threaded hole is provided on the top of the cabinet 1. During the assembly process, the bolt passes through the through hole on the fixing plate 73 and realizes a precise threaded connection with the threaded hole on the top of the cabinet 1, thereby ensuring a stable connection and fixation between the fixing plate 73 and the cabinet 1. This design not only simplifies the installation steps, but also ensures the reliability and stability of the connection.

[0096] Reference Fig.10 In another preferred embodiment of the present application, the fixing structure adopts a snap-on structure, and the specific implementation method is not limited. One feasible implementation method is as follows: a rotatable snap-on block is installed on the side wall of the top of the cabinet 1 facing the fixed plate 73, and the snap-on block forms a rotational connection with the side wall of the cabinet 1. A through hole matching the snap-on block is designed on the fixed plate 73. After the snap-on block passes through the through hole, the snap-on block is rotated to form a snap-on state with the through hole, thereby achieving a stable connection between the fixed plate 73 and the cabinet 1. The shape of the snap-on block is diverse, and it can be rectangular, triangular or special-shaped to meet the needs of different application scenarios. This snap-on structure not only facilitates quick assembly, but also ensures the firmness and convenience of the connection.

[0097] Reference Fig.11 In the embodiment of the present application, the top of the switch power module 13 outside the cabinet is provided with a terminal 131. The terminal 131 can be accurately inserted into the protective visor 7. This design not only effectively prevents the risk of malicious plugging and unplugging of the terminal 131, but also significantly improves the safety protection performance of the terminal 131. The shielding effect of the protective visor 7 provides additional protection for the terminal 131, avoids damage caused by external factors, and ensures the stable operation and safety performance of the power cabinet in outdoor environments.

[0098] In the embodiment of the present application, in order to improve the waterproof performance and stability of the switch power module 13 outside the cabinet, a waterproof shell 8 and a pressure plate 9 are arranged on the top of the switch power module 13 outside the cabinet. The waterproof shell 8 is cleverly arranged between the pressure plate 9 and the switch power module 13 outside the cabinet, forming a multiple waterproof barrier, which significantly enhances the waterproof effect of the module. The pressure plate 9 and one side of the waterproof shell 8 are passed through by bolts in sequence, and are threadedly connected with the top of the cabinet 1 to ensure the stable fixation of the entire structure. The other end of the pressure plate 9 is tightly pressed on the bottom of the plug-in terminal, which not only provides stability for the waterproof shell 8, but also provides reliable fixation for the wiring terminal 131, effectively avoiding the loosening phenomenon that may occur during use, and ensuring the stable operation and safety performance of the power module in various environments. This design not only improves the waterproof effect, but also enhances the stability and reliability of the structure, and provides a solid guarantee for the long-term stable operation of the power module. In addition, after the installation of the protective visor 7, its bottom is flush with the waterproof shell 8 to prevent rainwater from flowing back to the top of the cabinet 1 when it rains.
