Description

Technical Field

[0001] This application relates to the technical field of energy-saving control of switching power supplies, and more particularly, to an outdoor anti-theft power cabinet. Background Art

[0002] As an important device in the communication power system, the switching power cabinet provides stable and reliable power for communication devices, lighting devices, etc. It is the basis for the control and protection of the contemporary power system, and thus a large number of advanced scientific and technological applications are used.

[0003] Currently, in the prior art, the cabinet of the switching power cabinet mainly includes a cabinet body and a protective eaves. The traditional cabinet eaves are mostly directly welded inside the cabinet or pre-fastened to the cabinet body from the inside, and cannot be disassembled or are extremely difficult to disassemble. When unit modules need to be placed on the top of the cabinet in some usage scenarios, this traditional method cannot meet the usage requirements. If conventional techniques are used, the protective eaves are buckled on the top of the power cabinet and directly connected and fixed to the power cabinet through bolts. Since the bolts are exposed outside the power cabinet and the protective eaves, the protective eaves are extremely easy to disassemble, and there is a risk that the unit modules on the top of the cabinet body are stolen or maliciously damaged.

[0016] In an exemplary embodiment of the present application, the fixing structure is a bolt, and the bolt passes through the fixing plate and is threadedly connected to the side wall of the cabinet body.

[0017] In an exemplary embodiment of the present application, the fixing structure is a snap-fit structure, and after the fixing plate moves horizontally to abut against the front side of the cabinet body, it forms a snap-fit fixation with the cabinet body.

[0018] In an exemplary embodiment of the present application, it further includes an external cabinet switch power supply module, the external cabinet switch power supply module is installed outside the cabinet body, and after the protective brim is fixed, it can completely shield the wiring terminals on the upper part of the external cabinet switch power supply module.

After closing the cabinet door, lock the cabinet body with a safety lock, so that the fixing plate is located between the cabinet body and the cabinet door. Also, because the first matching structure and the second matching structure are located between the protective cap brim and the cabinet body, therefore, no structure for installing the protective cap brim is exposed on the outside. And when it is necessary to disassemble the protective cap brim, the safety lock and the cabinet door must be opened first. Therefore, through the above structure, it is difficult for the protective cap brim to be directly opened from the outside, so the risk of the power cabinet being stolen or maliciously damaged is effectively reduced.

[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 "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second" are used only as labels and are not a limitation on the quantity of their objects.

[0041] Refer to Figure 1 and Figure 2 As an embodiment of the present application, an outdoor anti-theft power cabinet is provided, including a cabinet body 1, a power supply compartment 11 for placing a power distribution unit is arranged in the cabinet body 1, and a battery compartment 12 for placing a storage battery 16, and further includes:

[0042] An external cabinet switch power supply module 13, at least one is provided, and is installed on the outer side of the cabinet body 1;

[0043] An internal cabinet switch power supply module 14, at least one is provided, and is installed inside the cabinet body 1 and around the power supply compartment 11;

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

[0045] In the embodiment of the present application, the power supply compartment 11 and the battery compartment 12 are arranged vertically inside the cabinet body 1, and the power supply compartment 11 is located directly above the battery compartment 12, but this layout is not fixed. It is also possible that the battery compartment 12 is placed above the power supply compartment 11, or the two can be arranged horizontally, and the power supply compartment 11 is located on one side of the battery compartment 12. The diversity of this design ensures the adaptability and practicability of the device in different scenarios.

[0046] In the embodiments of the present application, when the external environmental temperature is on the high side, the staff or the system can selectively activate the power supply module 13 outside the cabinet and simultaneously turn off the power supply module 14 inside the cabinet, thereby reducing the temperature around the storage battery 16 and avoiding overheating from affecting the performance of the storage battery 16. Conversely, when the external environmental temperature is on the low side, the staff or the system can selectively activate the power supply module 14 inside the cabinet and simultaneously reduce the power of the power supply module 13 outside the cabinet to zero, using the heat naturally dissipated when the power supply module 14 inside the cabinet operates to effectively increase the temperature of the environment around the storage battery 16 and ensure that the battery operates within a suitable temperature range. In addition, the staff or the system can also activate the power supply module 14 inside the cabinet and the power supply module 13 outside the cabinet simultaneously and flexibly adjust the power ratio between the two to achieve different temperatures at which the power supply module 14 inside the cabinet dissipates different amounts of heat, thereby providing different levels of temperature environments for the storage battery 16. This structure not only avoids the need for additional installation of air-conditioning equipment but also meets the environmental protection requirements of energy conservation and emission reduction.

[0047] Referring to Figure 3 , further, for the installation method between the power supply module 13 outside the cabinet and the cabinet body 1, the present application does not make special limitations and provides a variety of flexible fixing schemes. It can either be firmly connected by welding or bolt connection can be selected. The flexibility of this design aims to meet the requirements of different application scenarios and takes into account the convenience of installation and maintenance.

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

[0049] A fixing frame 21, fixedly connected to the outer wall of the cabinet body 1. The fixing frame 21 is provided with a slot 211 along the up-and-down direction, and the slot 211 penetrates the top of the fixing frame 21 but does not penetrate the bottom of the fixing frame 21;

[0050] A connecting frame 22, fixedly connected to the back of the power supply module 13 outside the cabinet. The connecting member is provided with a plug-in board 221 that is adaptively inserted into the slot 211.

[0051] In the embodiments of the present application, an angle is provided between the slot 211 and the plug-in board 221 to facilitate the staff to easily insert the plug-in board 221 into the slot 211 when installing the power supply module 13 outside the cabinet. This further facilitates the installation work of the staff.

[0052] The connection between the fixing bracket 21 and the cabinet body 1 can be welding or bolt connection, and there is no limitation in this regard; the same applies to the connection between the connecting bracket 22 and the external switch power supply module 13 of the cabinet. Of course, for the convenience of disassembling the fixing bracket 21 and the connecting bracket 22, the bolt connection method is preferably adopted.

[0053] To improve the stability of the external switch power supply module 13 after installation, two slots 211 are provided. The two slots 211 are respectively located on both sides of the side of the fixing bracket 21 facing away from the cabinet body 1, and two plug-in boards 221 are also provided on the corresponding connecting bracket 22.

[0054] Furthermore, a top plate 222 is fixedly provided at the top of the connecting bracket 22. When the plug-in board 221 is completely inserted into the slot 211, the lower surface of the top plate 222 is completely attached to the top of the fixing bracket 21.

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

[0056] When the external switch power supply module 13 is stably installed on the side wall of the cabinet body 1, the two plug-in boards 221 are in close contact with the bottom wall of the slot 211, and the top plate 222 abuts against the top wall of the fixing bracket 21, effectively increasing the contact area between the connecting bracket 22 and the fixing bracket 21, avoiding stress concentration, significantly improving the structural stability between the two, and ensuring the reliability of the equipment operation. In the embodiment of the present application, to ensure the power supply power 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 and the back of the cabinet body 1. Of course, the number and installation position of the external switch power supply module 13 are not restrictive.

[0057] Reference body 1 and Figure 3, in an embodiment of the present application, a cavity 15 that is recessed inward toward the battery compartment 12 is provided on the outer wall of the cabinet body 1 around the power supply compartment 11. The number of cavities 15 matches the number of the external switch power supply modules 13 outside the cabinet, ensuring that each external switch power supply module 13 is located within a cavity 15. The top of the cavity 15 penetrates through the top of the cabinet body 1, providing a smooth installation path for the external switch power supply modules 13. When the external switch power supply modules 13 are installed within the cavities 15, their outer surfaces do not protrude beyond the edges of the cavities 15, which means that the depth of the cavities 15 is not less than the thickness of the external switch power supply modules 13. Regarding the structure of the cavities 15, no special restrictions are imposed in the embodiments of the present application, as long as the external switch power supply modules 13 can be completely placed within them. Preferably, the left wall, right wall, and lower wall of the cavity are all provided as inclined surfaces to facilitate the heat dissipation of the switch power supply modules and improve the heat dissipation effect of the external switch power supply modules.

[0058] In the present application, the depth of the cavity 15 is greater than the thickness of the external switch power supply modules 13. The connection component 2 is used to make the outer surface of the external switch power supply modules 13 flush with the outer wall of the cabinet body 1 at the cavity 15, forming a neat and unified appearance. Moreover, there is enough distance between the outer wall of the cabinet body 1 at the cavity 15 and the external switch power supply modules 13 to ensure the heat dissipation requirements of the external switch power supply modules 13 themselves.

[0059] Referring to Figure 3 and Figure 6 , in an embodiment of the present application, a heat dissipation opening 111 is provided on the side wall of the cabinet body 1 at the power supply compartment 11, and a heat dissipation device 112 for exhausting the hot air in the power supply compartment 11 is provided inside the power supply compartment 11. The heat dissipation device 112 includes:

[0060] A heat dissipation fan 1121, with the blowing side facing the heat dissipation opening 111, for exhausting the hot air in the power supply compartment 11 from the heat dissipation opening 111;

[0061] A fixing cover 1122, installed at the heat dissipation opening 111 and provided with an opening on the side facing the heat dissipation opening 111. The heat dissipation fan 1121 is located inside the fixing cover 1122, and the air suction side of the heat dissipation fan 1121 extends out from the inside of the fixing cover 1122.

[0062] Through the continuous blowing of the heat dissipation fan 1121, the hot air in the power supply compartment 11 can be effectively and quickly exhausted from the heat dissipation opening 111, thereby achieving a significant cooling effect on the inside of the power supply compartment 11. The fixing cover 1122 forms a closure around the heat dissipation opening 111, preventing the hot air that fails to be exhausted from the heat dissipation opening 111 from flowing back into the power supply compartment 11, ensuring the efficiency of the heat dissipation process and significantly improving the cooling effect on the power supply compartment 11.

[0063] In an embodiment of the present application, a detachable connection is adopted between the cooling fan 1121 and the fixing cover 1122. Similarly, a detachable connection is also adopted between the fixing cover 1122 and the cabinet body 1, ensuring the independence and interchangeability of each component. When the cooling fan 1121 fails, the staff can easily detach the fixing cover 1122 together with the cooling fan 1121 from the side wall of the cabinet body 1 first, and then detach the cooling fan 1121 separately from the fixing cover 1122, which is convenient for replacement or maintenance. The detachable connection greatly facilitates the maintenance work of the equipment and improves the maintenance efficiency.

[0064] Referring to Figure 2 and Figure 7 , the power cabinet in the embodiment of the present application further includes:

[0065] A base 3, installed at the bottom of the cabinet body 1. An air outlet 31 for communicating with the base 3 is provided at the bottom of the cabinet body 1, and an air exhaust port 32 is penetrated through the side wall of the base 3;

[0066] An exhaust fan 4, installed inside the base 3 and located directly below the air outlet 31. The air outlet side of the exhaust fan 4 faces the air exhaust port 32, and is used to discharge the hot air in the cabinet body 1 from the air exhaust port 32.

[0067] In an embodiment of the present application, when the temperature in the battery compartment 12 reaches an excessive threshold and further cooling is required, the exhaust fan 4 will be started. The exhaust fan 4 sucks the hot air in the battery compartment 12 from the air outlet 31, conducts it into the interior of the base 3, and then discharges it from the air exhaust port 32. This process effectively realizes the further cooling of the battery compartment 12 and ensures the stable operation of the equipment. It should be noted that the air exhaust port 32 and the battery compartment 12 are not in a direct connection structure. This design has significant advantages: when the external environmental temperature is low and the temperature in the battery compartment 12 needs to be increased, 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 heat preservation effect, ensuring that the battery works within an appropriate temperature range, and improving the reliability and efficiency of the equipment.

[0068] 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 flow guide cover 5 is specifically provided in the battery compartment 12 along the vertical direction. The cross-section of the flow guide cover 5 is designed as an L shape, which is cleverly fitted to the inner corner of the cabinet body 1 and firmly connected to the inner wall of the cabinet body 1 by welding, ensuring the stability and reliability of the structure. A heat conduction channel 51 is formed between the flow guide cover 5 and the inner wall of the cabinet body 1. The bottom of the flow guide cover 5 is closely attached to the inner bottom wall of the battery compartment 12, while its top maintains a certain gap from 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 structure of the cross-section of the flow guide cover 5 is not limited to the L shape, and can also be a "return" shape, a "concave" shape, etc., to meet the requirements in different scenarios and improve the adaptability and flexibility of the equipment.

[0069] In an 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 accumulates 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 flow 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 exhaust port 32. This process makes full use of the structural advantages of the flow guide cover 5, effectively improving the cooling efficiency of the exhaust fan 4 for the battery compartment 12 and ensuring the precise control of the internal temperature of the battery compartment 12.

[0070] In an embodiment of the present application, in order to further improve the exhaust efficiency of the exhaust fan 4 for the hot air, a wind shield 41 is specifically provided at the air outlet 31. The top of the wind shield 41 is closely connected and fixed to the bottom of the flow guide cover 5, ensuring the stability and reliability of the structure. A through hole 411 is formed through the side walls between the top of the wind shield 41 and the bottom of the flow guide cover 5. This design enables the heat conduction channel 51 to be directly communicated with the inside of the wind shield 41, ensuring the smooth flow of hot air. The bottom of the wind shield 41 is connected and fixed to the exhaust fan 4. The air suction side of the exhaust fan 4 is installed inside 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 conveyed 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 the hot air, and ensuring the stable operation and efficient heat dissipation of the equipment.

[0071] Regarding the connection method between the wind shield 41 and the flow guide cover 5, and the connection method between the wind shield 41 and the exhaust fan 4, there are no strict restrictions. The connection method can adopt various methods such as gluing, welding, bolt connection, etc., but bolt connection is preferably adopted. The bolt connection method not only ensures the stability and reliability of the structure, but also facilitates the maintenance or replacement of the exhaust fan 4, 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 improves the temperature control ability of the device. The control method of the shutter 42 can be electric or non-electric, and we have not set strict restrictions on this to meet the requirements of different application scenarios. In the present application, a non-electric shutter 42 is selected. When the exhaust fan 4 blows air towards the shutter 42, the shutter 42 is automatically opened under the action of the wind force to ensure the smooth discharge of hot air. When the exhaust fan 4 stops blowing air, the shutter 42 can automatically close to further prevent cold air from entering the cabinet 1 through the exhaust port 32.

[0073] Referring to Figure 2 , in an embodiment of the present application, an air inlet 33 communicating with the base 3 is provided on the bottom wall of the battery compartment 12 of the cabinet 1, and an air inlet 34 is penetrated through the side wall of the base 3. This design ensures the smooth flow of air. When the exhaust fan 4 is started, hot air is discharged from the exhaust port 32, and a negative pressure environment is formed in the battery compartment 12. Then, the outside cold air is first inhaled into the base 3 through the air inlet 34, and then inhaled into the battery compartment 12 through the air inlet 33. Thus, the effect of air replacement in the battery compartment 12 is achieved. It should be noted that during the 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 direct-through structure. This design has significant advantages: when the outside ambient temperature is relatively low and it is necessary to heat the battery compartment 12, the exhaust fan 4 is not started at this time. Therefore, a negative pressure environment will not occur in the battery compartment 12, and cold air is not easily inhaled into the battery compartment 12, thereby effectively maintaining the temperature of the battery compartment 12, achieving a good heat preservation effect, ensuring that the battery works within an appropriate temperature range, and improving the reliability and efficiency of the device.

[0074] For the cleanliness inside the cabinet 1, a dust-proof device 6 is provided at the air inlet 33 or the air inlet 34. Of course, the dust-proof device 6 can also be provided at both the air inlet 33 and the air inlet 34 to achieve double protection. The dust-proof device 6 filters the air entering the cabinet 1, effectively preventing the intrusion of dust and impurities, and ensuring the cleanliness inside the cabinet 1 and the stable operation of the device. There are no special restrictions on the specific structure of the dust-proof device 6 to meet the requirements of different application scenarios. In the present application, a dust-proof cotton is used, which has good filtering effect and durability, can effectively block dust and impurities, and ensure the long-term cleanliness inside the power cabinet.

[0075] In an 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 heat-insulating layer is pasted on the inner wall of the battery compartment 12. The heat-insulating layer is made of heat-insulating cotton and has good heat-insulating performance, which can effectively reduce the influence of external temperature fluctuations on the temperature inside the battery compartment 12 and ensure that the battery operates stably within an appropriate temperature range. The setting of the heat-insulating layer not only improves the heat-insulating performance of the device, but also reduces the energy consumption of the device, improves the energy utilization efficiency, and provides guarantee for the long-term stable operation of the device.

[0076] Referring to Figure 2 , a placement plate 121 for placing the storage battery 16 and a bracket 122 for fixing the placement plate 121 are provided in the battery compartment 12, which ensures the stable placement and efficient heat dissipation of the storage battery 16. In the embodiment of the present application, there are four brackets 122, and the four brackets 122 are all arranged vertically and located at the four corners of the placement plate 121, ensuring the stability and balance of the placement plate 121. Both 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 and improving the stability and reliability of the device. The placement plate 121 can be correspondingly set with different numbers according to the actual number of storage batteries 16 placed in the battery compartment 12 as required to meet the requirements 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 storage batteries 16.

[0077] It should be noted that, in order to improve the heat dissipation effect of the storage battery 16, a plurality of ventilation holes 1211 are formed through the placement plate 121. The ventilation holes 1211 not only contribute to the heat dissipation at the bottom of the storage battery 16, but also ensure the ventilation effect inside the battery compartment 12. The setting of the ventilation holes 1211 improves the heat dissipation efficiency of the battery compartment 12, reduces the temperature inside the battery compartment 12, and improves the service life of the power cabinet.

[0078] Referring to Figure 1 、Referring to Figure 8 and Figure 9 , in the embodiment of the present application, the outdoor anti-theft power cabinet further includes: a protective eaves 7 buckled on the top of the cabinet body 1;

[0079] a cabinet door 17 arranged on the front side of the cabinet body 1 for closing the inside of the cabinet body 1, and a safety lock 171 for fixing is arranged between the two;

[0080] a first mating structure arranged on the side away from the front of the cabinet body 1 after the protective eaves 7 is installed on the top of the cabinet body 1;

[0081] The second mating structure is disposed on the side of the cabinet body 1 away from the cabinet door 17, and forms a fixed fit with the first mating structure when the protective eaves 7 is installed on the top of the cabinet body 1, and is hidden between the cabinet body 1 and the protective eaves 7 together with the first mating structure;

[0082] The fixing plate 73 is fixedly connected to the side of the protective eaves 7 close to the front of the cabinet body 1. After the protective eaves 7 is installed on the top of the cabinet body 1, the fixing plate 73 is located between the cabinet door 17 and the cabinet body 1;

[0083] The fixing structure is disposed between the cabinet body 1 and the fixing plate 73 and is used for fixedly connecting the fixing plate 73 and the cabinet body 1.

[0084] In this embodiment, no specific restrictions are imposed on the structure of the safety lock 171. The form of the safety lock 171 can be diversified. It can either follow the traditional mechanical lock to ensure its stability and reliability; or adopt an advanced Bluetooth lock to achieve remote control and intelligent management; or even 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 eaves 7, first, through the precise docking of the first mating structure and the second mating structure, a stable connection between one side of the protective eaves 7 and the back of the cabinet body 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 body 1 by using the fixing structure, and then the fixation of the other side of the protective eaves 7 and the front side of the cabinet body 1 is completed, 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 body 1 and the cabinet door 17, ensuring that the installation structure of the protective eaves 7 is completely not exposed, avoiding unnecessary safety hazards. The subtlety of this structure lies in that if it is necessary to disassemble the protective eaves 7, the cabinet door 17 must be opened first through the safety lock 171. This mechanism greatly improves the safety level of the power cabinet and effectively prevents the risk of theft or malicious damage to the unit module at the top of the cabinet body 1, providing a solid guarantee for the safety of the equipment.

[0086] In the embodiments of the present application, in order to significantly improve the convenience of installing the protective brim 7 and the cabinet body 1, the first mating structure and the second mating structure form a snap-fit structure. This snap-fit structure not only supports repeated installation and disassembly, but also does not cause any damage to the parts during the operation, ensuring the reliability and durability of long-term use. More importantly, the design of the snap-fit structure fully considers simplicity and cost-effectiveness, making the connection operation simple and convenient, greatly improving the work efficiency and bringing great convenience to the staff. The forms of the snap-fit structure are diverse. It can be a slot-type snap-fit structure, which realizes a stable connection through precise slot design; it can also be a hook-type snap-fit structure, which utilizes the flexibility of the hook to ensure quick installation and disassembly; it can also be a claw-type snap-fit structure, which provides additional safety through the gripping force of the claws. There are no special restrictions on the specific form of the snap-fit structure.

[0087] In the embodiments of the present application, the snap-fit structure between the protective brim 7 and the cabinet body 1 is further optimized. Specifically, the first mating structure and the second mating structure can be easily snap-fitted by horizontally moving the protective brim 7 towards the rear side of the cabinet body 1. This means that when the staff places the protective brim 7 on the top of the cabinet body 1, simply pushing the protective brim 7 horizontally backward can automatically complete the precise docking of the first mating structure and the second mating structure, forming a stable snap-fit state. Through the above structure, not only the operation efficiency is improved, but also the stability of the connection between the protective brim 7 and the cabinet body 1 is ensured, providing great convenience for the staff when installing the protective brim 7 and significantly improving the work efficiency and installation experience.

[0088] In a specific implementation manner in the embodiments of the present application, it aims to achieve a stable connection between the protective brim 7 and the cabinet body 1 while ensuring the simplicity and efficiency of the installation process. Specifically, the second mating structure is a hole structure or a snap-fit member 72; and the first mating structure includes a snap-fit plate 71, which is fixedly connected to the bottom of the protective brim 7. The snap-fit plate 71 can be coplanar with the side wall of the protective brim 7 or located inside the protective brim 7 and perpendicular to the side wall of the protective brim 7. When the snap-fit plate 71 is arranged inside the protective brim 7, the second mating structure is located on the top wall of the cabinet body 1; when the snap-fit plate 71 is arranged coplanar with the side wall of the protective brim 7, the second mating structure is arranged on the side wall of the top of the cabinet body 1.

[0089] The clamping plate 71 is provided with a clamping member 72 or a hole structure that is clamped and adapted to the second mating structure. Specifically, when the second mating structure adopts a hole structure, the clamping plate 71 is provided with a clamping member 72. Through the clamping cooperation between the clamping member 72 and the hole structure, a firm connection between the protective cap brim 7 and the cabinet body 1 is achieved. Conversely, when the second mating structure is a clamping member 72, the clamping plate 71 is provided with a hole structure. Through the precise docking between the clamping member 72 and the hole structure, the stability and reliability of the connection are also ensured. During the actual installation process, after the protective cap brim 7 is buckled on the top of the cabinet body 1, the clamping member 72 will accurately insert into the hole structure, and then by simply pushing the protective cap brim 7 horizontally, the clamping fixation can be easily achieved.

[0090] Furthermore, in the embodiment of the present application, to achieve a better connection effect and operation convenience. Specifically, the hole structure is provided on the clamping plate 71, and the hole structure penetrates the clamping plate 71. That is to say, the second mating structure is a clamping member 72, which forms a complement with the hole structure on the clamping plate 71 and together constitutes a clamping structure. The clamping plate 71 is arranged inside the protective cap brim 7, and the second mating structure, that is, the clamping member 72, is arranged on the top wall of the cabinet body 1. This layout not only optimizes the 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 body 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 body 1), and the other end is integrally and fixedly connected to the clamping portion 722, ensuring the stability and reliability of the connection. It should be noted that the cross-sectional dimension of the clamping portion 722 needs to be larger than that of the connecting portion 721. In the embodiment of the present application, the cross-sections of both the clamping portion 722 and the connecting portion 721 are circular. The connection method between the connecting portion 721 and the top wall of the cabinet body 1 is not particularly limited and can be welding, or bonding or threaded connection, etc.

[0092] Specifically, the hole structure is arranged on the clamping plate 71, and the hole structure is a series of holes 711. The series of holes 711 includes a first hole 7111 and a second hole 7112. It should be noted that the first hole 7111 is located on the side of the second hole 7112 away from the cabinet body 1 and the two are interconnected. The size of the first hole 7111 needs to be not less than the size of the clamping portion 722, and the size of the second hole 7112 needs to be less than the size of the clamping portion 722 but not less than the size of the connecting portion 721; the size of the connection between the first hole 7111 and the second hole 7112 is not less than the size of the connecting portion 721.

[0093] When the staff buckles the protective brim 7 above the top of the cabinet body 1, the second matching structure is located at the first hole 7111, the connecting part 721 is located inside the first hole 7111, and the clamping part 722 passes through from above the first hole 7111. After the staff pushes the protective brim 7, the connecting part 721 and the clamping part 722 are located at 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, realizing the clamping of the second matching structure and the first matching structure, thereby fixing the protective brim 7 above the cabinet body 1.

[0094] In the embodiment of the present application, after the first matching structure and the second matching structure are clamped, the fixing structure is used to fix the fixing plate 73 and the cabinet body 1.

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

[0096] Refer to Figure 10 , in another preferred embodiment of the present application, the fixing structure adopts a clamping structure, and the specific implementation method is not limited. One feasible implementation method is as follows: On the side wall of the cabinet body 1 facing the fixing plate 73 at the top, a rotatable clamping block is installed, and the clamping block is rotatably connected to the side wall of the cabinet body 1. The fixing plate 73 is designed with a through hole matching the clamping block. After the clamping block passes through the through hole, by rotating the clamping block, it forms a clamped state with the through hole, thereby realizing a firm connection between the fixing plate 73 and the cabinet body 1. The shape of the clamping block has diversity and can be rectangular, triangular or special-shaped to meet the requirements of different application scenarios. This clamping structure not only facilitates rapid assembly but also ensures the firmness and convenience of the connection.

[0097] Refer to Figure 11 , in the embodiment of the present application, the top of the off-cabinet switch power supply module 13 is provided with a terminal block 131. The terminal block 131 can be accurately inserted into the protective brim 7. This design not only effectively prevents the risk of malicious plugging and unplugging of the terminal block 131 but also significantly improves the safety protection performance of the terminal block 131. The shielding effect of the protective brim 7 provides additional protection for the terminal block 131, avoiding damage caused by external factors and ensuring the stable operation and safety performance of the power cabinet in the outdoor environment.

[0098] In the embodiment of the present application, in order to improve the waterproof performance and stability of the external cabinet switching power supply module 13, a waterproof shell 8 and a pressing plate 9 are provided at the top of the external cabinet switching power supply module 13. The waterproof shell 8 is ingeniously arranged between the pressing plate 9 and the external cabinet switching power supply module 13 to form multiple waterproof barriers, significantly enhancing the waterproof effect of the module. One side of the pressing plate 9 and the waterproof shell 8 are sequentially passed through by bolts and are threadedly connected to the top of the cabinet body 1, ensuring the firm fixation of the entire structure. The other end of the pressing plate 9 tightly presses on the bottom of the wiring terminal, not only providing stability for the waterproof shell 8, but also providing 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 supply module in various environments. This design not only improves the waterproof effect, but also enhances the stability and reliability of the structure, providing a solid guarantee for the long-term stable operation of the power supply module. In addition, after the installation of the protective eaves 7, the bottom of the protective eaves 7 is flush with the waterproof shell 8 to prevent rainwater from flowing back to the top of the cabinet body 1 when it rains.
