[0002] In today's telecommunications industry, with the promotion and application of green energy, more and more communication base stations are installing photovoltaic (PV) equipment to achieve energy conservation and emission reduction goals. However, traditional outdoor integrated cabinet PV equipment installation faces the following technical challenges and shortcomings:

[0003] I. Customized Installation of Photovoltaic Mounting Mounts: Outdoor photovoltaic mounting systems often require specialized design and customization based on factors such as latitude, cabinet orientation, and surrounding environmental conditions. This customization not only increases installation time and cost but also limits the rapid deployment and widespread use of photovoltaic equipment.

[0004] 2. Fixed Photovoltaic Module Angle: Existing photovoltaic support systems are typically set at a fixed angle, making it impossible to adjust according to seasonal changes or the sun's position throughout the day. This results in low power generation efficiency for the photovoltaic modules, especially under suboptimal lighting conditions, where they cannot fully realize their performance.

[0005] III. High Temperature Issues with Server Racks: In summer, outdoor integrated server racks are directly exposed to sunlight and are prone to high temperatures, leading to frequent high-temperature alarms. Solving this problem requires increased investment in the cooling system, thus increasing energy consumption and operating costs. Summary of the Invention

[0006] This invention provides a photovoltaic cabinet to solve the problems of existing photovoltaic cabinets, which require customized installation of photovoltaic modules, resulting in complex installation, inflexible adjustment, and high temperature issues.

[0014] Furthermore, the fixed bracket includes a rectangular frame and reinforcing beams disposed inside the area surrounding the rectangular frame. The rectangular frame has multiple second mounting points for connecting to the cabinet body, and the multiple second mounting points are symmetrically distributed on two frame beams in the width direction of the rectangular frame.

[0015] Furthermore, the angle adjustment bracket is an isosceles triangular frame structure, which includes a base frame, a support frame, and two symmetrical side frames. The two side frames are connected to the base frame sequentially end to end. One end of the support frame is connected to the intersection of the two side frames, and the other end of the support frame is connected to the middle position of the base frame.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 5 As shown, an embodiment of the present invention provides a photovoltaic cabinet, which includes a cabinet body 10, a bracket assembly 20 and a photovoltaic module 30. The bracket assembly 20 is disposed on one side of the cabinet body 10 and its installation position on the side of the cabinet body 10 is adjustable. The photovoltaic module 30 is disposed on the bracket assembly 20 and its installation position on the bracket assembly 20 is adjustable, so that the photovoltaic module 30 covers at least part of the top of the cabinet body 10.

[0036] The bracket assembly 20 is rotatably configured to adjust the azimuth angle of the photovoltaic module 30 in the horizontal direction. The photovoltaic module 30 is mounted on the bracket assembly 20, and the tilt angle of the photovoltaic module 30 in the vertical direction is adjustable.

[0037] This photovoltaic (PV) cabinet solution achieves flexible installation and multi-degree-of-freedom adjustment of the PV modules 30 through adjustments to the mounting position of the bracket assembly 20 on one side of the cabinet body 10, the rotation of the bracket assembly 20, and the tilt angle of the PV modules 30. Compared to traditional fixed brackets for mounting PV modules 30 on one side of the cabinet body 10, this solution eliminates the need for custom-made fixed brackets for each location on the cabinet body 10, simplifying the installation process, shortening the construction cycle, and reducing costs. It also improves the applicability of the PV modules 30, making them adaptable to different regions, outdoor cabinet body 10 locations, and cabinet body 10 orientations. This allows the PV modules 30 to adjust to the optimal light reception angle based on different environmental factors (latitude, seasonal changes, etc.), thereby improving solar energy conversion efficiency and maximizing power generation. Furthermore, the PV modules 30 cover at least part of the top of the cabinet body 10, providing partial shading. This reduces heat conduction from direct sunlight on the top of the cabinet body 10 while the PV modules 30 generate electricity, contributing to energy conservation.

[0038] The photovoltaic cabinet also includes a first fastening component 41. One side of the cabinet body 10 has multiple first transition areas distributed along the length and / or height of the cabinet body 10. The bracket assembly 20 is detachably installed in one of the first transition areas by means of the first fastening component 41; or, the bracket assembly 20 is fixed in one of the first transition areas by means of the first fastening component 41.

[0039] This configuration allows for adjustment of the mounting position of the bracket assembly 20 in both the horizontal and vertical directions. When the position of the photovoltaic module 30 needs to be adjusted, the first fastening component 41 is loosened or removed to loosen or disconnect the connection between the bracket assembly 20 and the cabinet body 10. After moving the bracket assembly 20 to the new first transition area, the first fastening component 41 is tightened again, thus completing the adjustment of the mounting position of the bracket assembly 20 and the position of the photovoltaic module 30. The first fastening component 41 enables a flexible connection between the bracket assembly 20 and the cabinet body 10, ensuring structural stability and providing adjustability of the mounting position. This improves the adaptability and maintenance convenience of the photovoltaic cabinet, allowing for quick and convenient adjustment of the position of the photovoltaic module 30 without damaging the original structure.

[0040] In this embodiment, multiple first transition areas are arranged in m rows and n columns, where the values ​​of m and n can be adjusted according to actual conditions. One side of the cabinet body 10 has multiple first transition areas distributed along the length of the cabinet body 10. These multiple first transition areas are spaced apart or at least partially overlap. The installation height of the bracket assembly 20 within any of the first transition areas is adjustable (this can be understood as the multiple first transition areas in this embodiment being arranged in 1 row and 3 columns, and the installation position of the bracket assembly 20 along the height direction in the same column of first transition areas being adjustable). Each first transition area includes multiple first mounting points, and one side of the bracket assembly 20 has multiple second mounting points distributed circumferentially along that side. The multiple first mounting points in the same first transition area are detachably connected to the multiple second mounting points via a first fastening component 41. This configuration, through the matching connection of multiple second mounting points with multiple first mounting points, achieves precise positioning and secure fixing of the bracket assembly 20 on the first transition areas of the cabinet body 10, enhancing the stability of the installation and the overall structure of the photovoltaic cabinet.

[0041] like Figures 1 to 4 As shown, the bracket assembly 20 includes a fixed bracket 21 disposed on one side of the cabinet body 10 and with an adjustable mounting position. The fixed bracket 21 includes a rectangular frame 211 and reinforcing beams 212 disposed within the area surrounding the rectangular frame 211. The rectangular frame 211 has multiple second mounting points for connecting to the cabinet body 10, and the multiple second mounting points are symmetrically distributed on two frame beams in the width direction of the rectangular frame 211. This arrangement enhances the structural strength of the fixed bracket 21 through the reinforcing beams 212, while the symmetrically distributed second mounting points provide a stable connection to the cabinet body 10, which helps to improve the overall structural stability of the photovoltaic cabinet and ensures the safe operation of the photovoltaic modules even under extreme weather conditions.

[0042] In this embodiment, the cabinet body 10 has 18 first mounting points on one side, arranged in 6 columns, with each column including 3 first mounting points. The left two columns of first mounting points form a first transition area, the middle two columns form a first transition area, and the right two columns form a first transition area. The three first transition areas are spaced apart. The rectangular frame 211 is sized to fit one of the first transition areas and has 6 second mounting points on it. When the rectangular frame 211 is installed directly on one of the first transition areas, the 6 first mounting points connect via the first... A fastening component 41 is detachably connected to six second mounting points in a one-to-one correspondence. When it is necessary to adjust the mounting position of the rectangular frame 211 on the first transition area, the rectangular frame 211 is simply moved upward during installation. The two uppermost second mounting points of the rectangular frame 211 protrude out of the largest area formed by all the first transition areas. The remaining four second mounting points of the rectangular frame 211 are detachably connected to the four first mounting points in the corresponding first transition areas in a one-to-one correspondence (that is, the two second mounting points at the top of the rectangular frame 211 and the two first mounting points at the bottom of the first transition area are not connected in a corresponding manner).

[0043] In another embodiment (not shown), the first transition areas of two adjacent columns may partially overlap, that is, the first transition area of ​​the previous column and the first transition area of ​​the next column share the same first mounting point. Compared with the above embodiment, the number of first mounting points in this embodiment is 12 (4 columns, 3 first mounting points per column), while ensuring that three first transition areas are formed.

[0044] It should be noted that the dimensions and shape of the rectangular frame 211, the number and distribution of the reinforcing beams 212, the number and distribution of the second installation points, the number and distribution of the first transition area, and the number and distribution of the first installation points included in the first transition area can all be adjusted adaptively according to the actual situation.

[0045] Preferably, in this embodiment, the first fastening component 41 is an adapter and an adapter screw.

[0046] Optionally, the adjustment of the mounting position of the bracket assembly 20 on one side of the cabinet body 10 can be achieved in other ways while ensuring the stability of the photovoltaic module 30. For example, in other embodiments not shown in the figure, one side of the cabinet body 10 has a first slide rail that passes through multiple first transition areas. The bracket assembly 20 is correspondingly provided with a first sliding member. One end of the first sliding member extends into the first slide rail and is slidably disposed to adjust the bracket assembly 20 to one of the first transition areas. The first fastening component 41 is used to fix the bracket assembly 20 at one of the first transition areas. In this embodiment, the bracket assembly 20 is slidably mounted on one side of the cabinet body 10 and tightened or loosened by the first fastening component 41. When the first fastening component 41 is loosened or removed, the bracket assembly 20 slides along the first slide rail to the required first transition area. Then, the first fastening component 41 is used to lock or restrict its sliding to complete the position adjustment. Through the cooperation of the first slide rail and the first sliding member, smooth movement on the side of the cabinet body 10 is achieved, which facilitates quick adjustment of the position of the bracket assembly 20, simplifies the installation and adjustment process of the photovoltaic module 30, and improves work efficiency. The structure and fit of the first slide rail and the first sliding member can be adapted to the actual situation. It is only necessary to ensure that the first sliding member will not easily come out of or shift from the first slide rail. The selection of the first fastening component 41 and its relative tightness to the bracket assembly 20 and the cabinet body 10 can also be designed and adjusted according to the actual situation. For example, at least two second mounting holes are provided near each first transition area, the bracket assembly 20 has a corresponding number of first mounting holes, and the first fastening component 41 is an adapter seat and an adapter screw. After the bracket assembly 20 is slid to the first transition area to be installed, the two are connected by multiple first fastening components 41 to avoid relative rotation and relative sliding between the two.

[0047] Specifically, the photovoltaic cabinet also includes a second fastening component 42 and a hinge component 44. The photovoltaic module 30 has multiple second transition areas distributed along the length and / or width direction of the photovoltaic module 30. The bracket assembly 20 is detachably hinged to one of the second transition areas via the hinge component 44 and the second fastening component 42; or, the bracket assembly 20 is hinged to the photovoltaic module 30 via the hinge component 44 and fixed to one of the second transition areas via the second fastening component 42. This configuration allows for adjustment of the installation position of the photovoltaic module 30 on the bracket assembly 20. The hinge component 44 enables flexible connection between the photovoltaic module 30 and the bracket assembly 20, facilitating adjustment of the tilt angle of the photovoltaic module 30 according to the light angle. The second fastening component 42 is used to limit the connection position of the photovoltaic module 30 on the bracket assembly 20, ensuring the stability of the photovoltaic module.

[0048] The multiple second transition areas can also be arranged in m rows and n columns, and the values ​​of m and n can be adjusted according to the actual situation. In this embodiment, the photovoltaic module 30 has multiple second transition areas distributed along the width direction of the photovoltaic module 30. The multiple second transition areas are spaced apart or at least partially overlapped. The installation height of the bracket assembly 20 in any first transition area is adjustable (it can be understood that the multiple first transition areas in this embodiment are distributed in 1 row and 3 columns, and the installation position of the bracket assembly 20 in the same column of first transition areas along the height direction is adjustable). Any second transition area includes multiple third mounting points, and the top of the bracket assembly 20 has multiple fourth mounting points spaced apart along the same direction. The multiple third mounting points in the same second transition area are detachably connected to the multiple fourth mounting points through the hinge assembly 44 and the second fastening assembly 42. With this configuration, the precise installation and angle adjustment of the photovoltaic module 30 on the bracket assembly 20 are achieved through the matching connection of the third and fourth mounting points and the transition of the hinge assembly 44, thereby enhancing the installation accuracy and stability of the photovoltaic module 30.

[0049] Preferably, the position of the photovoltaic module 30 in the length direction within any second transition area is adjustable (which can be understood as the multiple second transition areas in this embodiment being distributed in 1 row and 2 columns, and the installation position of the bracket assembly 20 in the length direction of the same column of the first transition area being adjustable, wherein the row is the width direction and the column is the length direction).

[0050] like Figures 1 to 3As shown, the support assembly 20 also includes an angle adjustment bracket 22 and an elevation angle adjuster 23. The angle adjustment bracket 22 is mounted on the fixed bracket 21 and its rotation angle relative to the fixed bracket 21 is adjustable. The photovoltaic module 30 is hinged to the angle adjustment bracket 22 in an adjustable position via a hinge assembly 44 and a second fastening assembly 42. One end of the elevation angle adjuster 23 is hinged to the angle adjustment bracket 22, and the other end of the elevation angle adjuster 23 is slidably hinged to the photovoltaic module 30 to adjust the tilt angle of the photovoltaic module 30. This configuration allows for omnidirectional angle adjustment of the photovoltaic module 30 via the angle adjustment bracket 22 and the elevation angle adjuster 23 to adapt to different lighting conditions, thereby improving the power generation efficiency of the photovoltaic module 30 and achieving optimal light reception in various environments. The angle adjustment bracket 22 is an isosceles triangular frame structure, comprising a base frame 221, a support frame 223, and two symmetrical side frames 222. The two side frames 222 are sequentially connected to the base frame 221 end-to-end. One end of the support frame 223 is connected to the intersection of the two side frames 222, and the other end of the support frame 223 is connected to the middle position of the base frame 221. The side of the base frame 221 facing away from the support frame 223 has multiple fourth mounting points for connecting to the photovoltaic module 30. These fourth mounting points are distributed at least at the transition points between the base frame 221 and one of the side frames 222, between the base frame 221 and the support frame 223, and between the base frame 221 and the other side frame 222. This arrangement utilizes the stability of the isosceles triangular frame structure, achieving secure fixing and angle adjustment of the photovoltaic module 30 through multiple fourth mounting points. It also facilitates the hinged rotation adjustment of the photovoltaic module 30, improving the installation accuracy and stability of the photovoltaic module 30 and enhancing the overall structural strength of the photovoltaic cabinet. On the other hand, the photovoltaic module 30 includes a photovoltaic support 31 and a photovoltaic panel 32 mounted on the photovoltaic support 31. The photovoltaic support 31 has multiple rows of third mounting points on the side facing the support assembly 20 for connection with the support assembly 20. The multiple rows of third mounting points are spaced apart along the width direction of the photovoltaic support 31, and the support assembly 20 is hinged to one of the rows of third mounting points. The multiple rows of third mounting points enable precise connection and angle adjustment between the photovoltaic module 30 and the support assembly 20, improving the installation accuracy and stability of the photovoltaic module 30.

[0051] In this embodiment, the photovoltaic bracket 31 has two long brackets 311 at its bottom and three short brackets 312 spaced apart between the two long brackets 311. At least one third mounting point is formed in the middle of any one of the short brackets 312. The three short brackets 312 correspond to at least one set of second transition areas. The base frame 221 has three fourth mounting points. When the angle adjustment bracket 22 is directly opposite the second transition area mounted on one of the photovoltaic brackets 31, the three fourth mounting points are detachably hinged to the three third mounting points in the same set of second transition areas via hinge components 44 and second fastening components 42. When it is necessary to adjust the installation position of the photovoltaic module 30 along the length of the second transition area, the photovoltaic bracket 31 is simply moved along the length of the base frame 221 during installation, so that one of the third mounting points protrudes from the base frame 221, and the other two third mounting points are detachably hinged to the two fourth mounting points in the corresponding second transition areas.

[0052] Preferably, the short support 312 has a limiting slide 3121, and the elevation adjuster 23 includes an adjusting rod and two adapter seats. The two ends of the adjusting rod are hinged to the two adapter seats respectively. One adapter seat is mounted on the support frame 223, and the other adapter seat is slidably mounted within the limiting slide 3121. The elevation adjuster 23 can adjust the tilt angle of the photovoltaic module 30 relative to the horizontal plane within the range of 10° to 30°. The number of photovoltaic panels 32 can be adjusted according to actual conditions.

[0053] It should be noted that the composition of the photovoltaic bracket 31, the selection and distribution of the third installation point and the second transition area, the composition of the angle adjustment bracket 22, and the selection and distribution of the fourth installation point can all be adapted according to the actual situation, and will not be listed one by one here.

[0054] Preferably, in this embodiment, the second fastening component 42 is an adapter screw, and the hinge component 44 is a hinge seat.

[0055] Optionally, the adjustment of the installation position of the photovoltaic module 30 on the bracket assembly 20 can also be achieved in other ways. For example, in other embodiments not shown in the figure, on the basis of ensuring the stability of the photovoltaic module 30, one side of the cabinet body 10 has a second slide rail and a second sliding member slidably disposed in the second slide rail. The bracket assembly 20 is hinged to the second sliding member by the hinge assembly 44, and the second fastening assembly 42 is used to fix the bracket assembly 20 at one of the second transition areas.

[0056] In this embodiment, the photovoltaic bracket 31 is slidably hinged to one side of the angle adjustment bracket 22 via a hinge assembly 44 and tightened / loosened by a second fastening assembly 42. When the second fastening assembly 42 is loosened or removed, the photovoltaic bracket 31 can slide to the desired second transition area. Then, the second fastening assembly 42 is used to lock or restrict its sliding, completing the position adjustment. Through the cooperation of the second slide rail and the second sliding member, smooth movement and adjustment of the photovoltaic module 30 relative to the cabinet body 10 are achieved, improving the flexibility and maintainability of the photovoltaic cabinet. The structure and cooperation of the second slide rail and the second sliding member can be adaptively designed according to actual conditions, as long as the second sliding member does not easily detach or shift from the second slide rail. The selection of the second fastening assembly 42 and its relative tightening / loosening method to the photovoltaic module 30 and the angle adjustment bracket 22 can also be designed and adjusted according to actual conditions.

[0057] like Figures 1 to 3 As shown, the angle adjustment bracket 22 also includes adapter plates 224 disposed at the connection positions of the two side frames 222 and the support frame 223. The fixed bracket 21 includes an adapter seat 213 located on top of the fixed bracket 21. The photovoltaic cabinet also includes a third fastening component 43. The adapter plate 224 has multiple fifth mounting points distributed circumferentially, and the adapter seat 213 has multiple sixth mounting points distributed circumferentially. The multiple fifth mounting points are detachably connected to the multiple sixth mounting points one-to-one through the third fastening component 43. With this configuration, the adapter plate 224 and the adapter seat 213 cooperate to achieve flexible connection and angle adjustment between the angle adjustment bracket 22 and the fixed bracket 21. The third fastening component 43 is used to lock this connection state, improving the flexibility and maintainability of the photovoltaic cabinet, and enabling quick adjustment of the position and angle of the photovoltaic modules without damaging the original structure. Preferably, the third fastening component 43 is a fastening screw.

[0058] In other embodiments (not shown), to ensure the stability of the photovoltaic module 30, the angle adjustment bracket 22 further includes a transition plate 224 disposed at the connection position between the two side frames 222 and the support frame 223. The fixed bracket 21 includes a transition seat 213 located at the top of the fixed bracket 21. The photovoltaic cabinet also includes a third fastening component 43. The transition plate 224 has a third slide rail extending circumferentially, and the transition seat 213 is correspondingly provided with a third sliding member. One end of the third sliding member is disposed within the third slide rail and is slidably disposed. The third fastening component 43 is used to restrict the relative rotation of the transition plate 224 and the transition seat 213. With this configuration, the relative rotation adjustment of the angle adjustment bracket 22 and the fixed bracket 21 can be achieved without disassembling them through the cooperation of the third slide rail and the third sliding member, improving the convenience of adjusting the angle of the photovoltaic module 30. The selection of the third fastening component 43 in this embodiment and its relative tightening method with respect to the transition plate 224 and the transition seat 213 can also be designed and adjusted according to actual conditions, and will not be listed here.

[0059] like Figure 5 As shown, the cabinet body 10 includes a cabinet 11 and a communication power supply 12, communication equipment 13, cabinet door air conditioner 14 and DC bus 15 installed in the cabinet 11. The photovoltaic cabinet also includes a combiner box 51 and an adapter 52. The photovoltaic module 30, adapter 52, combiner box 51 and DC bus 15 are electrically connected in sequence. The DC bus 15 is electrically connected to the communication equipment 13 and the cabinet door air conditioner 14. The communication power supply 12 supplies power to the DC bus 15. The cabinet 11 is made of heat-insulating material or has a heat-insulating design.

[0060] In this embodiment, adapter 52 is a DC / DC converter that boosts the voltage of photovoltaic module 30 to -48V for connection. The system voltage is below the safe voltage, ensuring high safety. Cabinet air conditioner 14 is a DC inverter air conditioner, primarily used during the day, coinciding with solar power generation. This allows it to absorb photovoltaic power, increasing the green electricity ratio of the base station and achieving high energy efficiency. The power generated by photovoltaic module 30 is boosted to -48V by adapter 52 and then connected to DC bus 15 via combiner box 51, ultimately powering communication equipment 13 and cabinet air conditioner 14, achieving self-absorption and efficient utilization of green electricity. Connecting the green electricity generated by photovoltaic module 30 to communication equipment 13 and cabinet air conditioner 14 via DC bus 15 enables direct supply and efficient utilization of green electricity, significantly reducing the energy consumption of the communication base station and achieving energy conservation and emission reduction goals. Furthermore, the photovoltaic cabinet employs heat-insulating materials to reduce heat conduction and achieve energy savings. In the case of multiple photovoltaic panels 32, the power generated by any one photovoltaic panel 32 is stepped up to -48V through a corresponding adapter 52 and then connected in parallel to the combiner box 51.
