Description

Technical Field

[0001] This invention relates to the field of photovoltaic charging equipment technology, specifically to a transformer substation charging device with a photovoltaic panel lifting structure. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific cable laying scheme. It is typically laid underground using direct burial or conduit protection. Cable heads are made at both ends and crimped with terminals, then the cables are threaded through pre-drilled openings into the substation. High-voltage and low-voltage cables are connected to the corresponding high-voltage incoming and low-voltage outgoing cabinets inside the substation, respectively. The prefabricated structure is particularly suitable for urban power grid construction and renovation. With the global energy structure transformation, solar energy has become a key development direction due to its clean and renewable characteristics. The maturity of photovoltaic power generation technology and its continuously decreasing costs provide a technological foundation for charging devices. Utilizing the steel structure box as support, photovoltaic panels are fixed to the top via brackets, forming a "solar canopy" structure. This is currently the most common approach to achieving "photovoltaic + charging" integration. This method requires no additional land acquisition and can utilize the substation's own space for self-generation and self-consumption, making it particularly suitable for land-scarce urban streets and small parking lots.

[0003] The wind resistance of existing fixed photovoltaic transformer substations relies heavily on the passive strength of the support structure. Once they encounter strong winds exceeding the design reference period, not only will the photovoltaic system itself face devastating damage, but it will also trigger a chain of safety risks such as electric shock, fire, and falling objects from heights, posing a huge threat to people's lives and property. This greatly limits the promotion and application of integrated photovoltaic, energy storage, and charging transformer substations in windy areas and inland areas with strong winds.

One end of the spring is fixedly connected to one side of the outer wall of the support seat, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0007] Preferably, a connecting column is fixedly connected to the bottom center of the disc base, and a movable hole is opened through the top of the support base corresponding to the connecting column. A limiting plate is fixedly connected to the bottom of the connecting column, and the top of the limiting plate slides against the inner wall of the top of the support base. The outer diameter of the limiting plate is larger than the inner diameter of the movable hole.

[0008] Preferably, a tension spring is fixedly connected to the bottom of the limiting plate, and a connecting block is fixedly connected to the bottom of the tension spring. A snap-fit ​​block is fixedly connected to the bottom of the connecting block, and the bottom of the snap-fit ​​block extends through the bottom of the support base to the outside. A snap-fit ​​groove is opened on the inner wall of the slide groove corresponding to the snap-fit ​​block, and the extended end of the snap-fit ​​block is slidably connected to the inner wall of the snap-fit ​​groove.

[0009] Preferably, the inner wall of the support base is fixedly connected with springs two at equal intervals, and the other end of spring two is fixedly connected to the top inclined surface of the connecting block with an inclined direction facing downward.

[0010] Preferably, the horizontal return component includes: The inner wall of the connecting groove has symmetrically opened grooves. A spring three is fixedly connected to the inner wall of the groove, and a locking post is fixedly connected to the other end of the spring three. The other end of the locking post is frustum-shaped. A lifting rod is fixedly connected to the bottom of the mounting plate, and the bottom of the lifting rod extends through the top of the box and into its interior.

[0011] Preferably, a mounting plate is fixedly connected to one end of the fixed shaft located at the rear side of the frame, and a torsion spring is fixedly connected to one end face of the mounting plate facing the sleeve, and the other end of the torsion spring is fixedly connected to one side outer wall of the sleeve.

[0012] Preferably, the offset tracking component includes a drive motor fixedly mounted on the top of the mounting plate. One end of the drive motor's output shaft is fixedly connected to a drive gear, and the top of the drive gear is meshed with a driven gear. One end face of the driven gear is fixedly connected to one end of a fixed shaft located on the front side of the frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. During the photovoltaic power generation operation of this charging device, under normal operating conditions, the locking block at the bottom of the support base is firmly embedded in the locking groove at the top of the housing under the action of spring two, providing basic support force. When encountering low-intensity wind, the wind pressure acts on the surface of the photovoltaic module and is transmitted to the disc base through the connecting rod, thereby causing the locking block to detach through the tension spring. At this time, spring two will prevent the locking block from detaching and will be compressed, converting the impact kinetic energy of the wind into elastic potential energy, allowing the photovoltaic module to make slight swaying within a limited range, thus effectively avoiding the rigid structure from being damaged by wind. To prevent metal fatigue fracture caused by vibration, when the wind force is too strong, the tension spring pulls the locking block out of the locking slot, allowing the photovoltaic module to fall into the top space of the box. This not only lowers the overall center of gravity of the photovoltaic module, but also uses the top space of the box to protect the photovoltaic module, blocking hard objects such as sand, gravel and branches blown by the wind and preventing them from impacting the solar cells at high speed. At the same time, during the descent, the spring can provide a reverse deceleration force to ensure a soft landing of the photovoltaic module, protecting the glass cover and solar cells from damage, thus helping to ensure the stability of the device.

[0014] 2. During the photovoltaic power generation process of this charging device, under normal power generation conditions, the photovoltaic module can be slowly tilted and offset by the drive motor according to a preset program or light sensor feedback, so that the incident angle of the oblique sunlight during the morning and evening hours is closer to vertical, which can effectively improve the power generation efficiency during low light periods.

[0015] 3. During the photovoltaic power generation process of this charging device, when the photovoltaic module is lowered due to excessive wind, the locking post design allows the mounting plate to disengage from the connecting rod simultaneously upon separation. This disengages the drive gear from the driven gear, and the torsion spring then corrects the photovoltaic module's offset angle to a horizontal position, preventing it from tilting and falling and causing impacts. This ensures that the photovoltaic module smoothly and without jamming completely sinks into the top space of the housing, thus contributing to the stability of the device.

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figures 1-9 The present invention provides a box-type substation charging device with a photovoltaic panel lifting structure, including a box 1, a substation room 2 installed inside the box 1, and a frame 3 set on the top of the box 1, with a photovoltaic module 4 installed inside the frame 3.

[0020] The top of the housing 1 is provided with a buffer protection component 5. The buffer protection component 5 includes fixed shafts 501 fixedly connected to the middle of the front and rear sides of the frame 3 respectively. The outer walls of the two fixed shafts 501 are rotatably connected with sleeves 502, and the two sides of the sleeves 502 are respectively hinged with connecting rods 503. The bottom of the connecting rods 503 is provided with a movable release component.

[0021] Furthermore, the detachable components include: A connecting column 510 is fixedly connected to the bottom center of the disc base 504. A movable hole 511 is opened through the top of the support base 505 corresponding to the connecting column 510. A limiting plate 512 is fixedly connected to the bottom of the connecting column 510. The top of the limiting plate 512 slides against the inner wall of the top of the support base 505. The outer diameter of the limiting plate 512 is larger than the inner diameter of the movable hole 511.

[0022] A tension spring 513 is fixedly connected to the bottom of the limiting plate 512, and a connecting block 514 is fixedly connected to the bottom of the tension spring 513. A snap-fit ​​block 515 is fixedly connected to the bottom of the connecting block 514, and the bottom of the snap-fit ​​block 515 extends to the outside through the bottom of the support base 505. A snap-fit ​​groove 516 is opened on the inner wall of the slide groove 506 corresponding to the snap-fit ​​block 515. The extended end of the snap-fit ​​block 515 is slidably connected to the inner wall of the snap-fit ​​groove 516. A second spring 517 is fixedly connected at equal intervals to the inner wall of the support base 505, and the other end of the second spring 517 is fixedly connected to the top inclined surface of the connecting block 514 with an inclined downward orientation.

[0023] In this embodiment, during the photovoltaic power generation process of this charging device, a connecting column 510 is fixedly connected to the bottom center of the disc base 504. The top of the support base 505 is provided with a movable hole 511 through the connecting column 510. The bottom of the connecting column 510 is fixedly connected to a limiting disk 512, and the top of the limiting disk 512 slides against the inner wall of the top of the support base 505. The outer diameter of the limiting disk 512 is larger than the inner diameter of the movable hole 511. Thus, when encountering a low-intensity wind, the wind pressure acts on the surface of the photovoltaic module 4 and is transmitted to the disc base 504 through the connecting rod 503, causing the disc base 504 to move in the direction of the wind on the top surface of the support base 505.

[0024] Next, a tension spring 513 is fixedly connected to the bottom of the limiting plate 512, and a connecting block 514 is fixedly connected to the bottom of the tension spring 513. A snap-fit ​​block 515 is fixedly connected to the bottom of the connecting block 514, and the bottom of the snap-fit ​​block 515 extends outward through the bottom of the support base 505. A snap-fit ​​groove 516 is opened on the inner wall of the slide groove 506 corresponding to the snap-fit ​​block 515. The extended end of the snap-fit ​​block 515 is slidably connected to the inner wall of the snap-fit ​​groove 516. Springs 517 are fixedly connected at equal intervals to the inner wall of the support base 505, and the other end of the springs 517 is fixedly connected to the top of the connecting block 514 at an angle downward. When the disc base 504 moves horizontally, the tension spring 513 is stretched, providing a lifting force to the snap-fit ​​block 515 located in the snap-fit ​​groove 516 that varies with the wind intensity. At this time, through the setting of several springs 517, during the process of the tension spring 513 driving the snap-fit ​​block 515 to disengage, the several springs 517 will be compressed to prevent the snap-fit ​​block 515 from disengaging, converting the impact kinetic energy of the wind into elastic potential energy, allowing the photovoltaic module 4 to make micro-swaying within a limited range, thereby effectively avoiding metal fatigue fracture caused by wind-induced vibration of the rigid structure.

[0025] Furthermore, a disc base 504 is hinged to one end of the connecting rod 503. A support seat 505 is slidably connected to the bottom of the disc base 504. A groove 506 is provided on the top of the housing 1 corresponding to the support seat 505. The outer wall of the support seat 505 is slidably connected to the groove 506. A slide rod 507 is fixedly connected to one side of the outer wall of the support seat 505. A limiting groove 508 is provided on the inner wall of the groove 506 corresponding to the slide rod 507. The outer wall of the slide rod 507 is slidably connected to the inner wall of the limiting groove 508. A spring 509 is provided on the outer wall of the slide rod 507. One end of the spring 509 is fixedly connected to one side of the outer wall of the support seat 505, and the other end of the spring 509 is fixedly connected to the inner wall of the groove 506.

[0026] Specifically, when the wind force is too strong, the tension spring 513 pulls the locking block 515 out of the locking groove 516. At this time, the two sets of connecting rods 503 will open and move downward, so that the photovoltaic module 4 will fall into the top space of the box 1. This not only lowers the overall center of gravity of the photovoltaic module 4, but also uses the top space of the box 1 to protect the photovoltaic module 4, blocking hard objects such as sand and branches blown by the wind and preventing them from impacting the battery cells at high speed. At the same time, during the descent, the spring 509 can provide a reverse deceleration force to ensure that the photovoltaic module 4 lands softly, protecting the glass cover and battery cells from damage, thus helping to ensure the stability of the device.

[0027] In Example 2, based on the above examples, the top of the housing 1 is further provided with an offset tracking component 7.

[0028] Furthermore, the offset tracking component 7 includes a drive motor 701 fixedly mounted on the top of the mounting plate 601. One end of the drive motor 701 is fixedly connected to a drive gear 702, and the top of the drive gear 702 is meshed with a driven gear 703. One end face of the driven gear 703 is fixedly connected to one end of a fixed shaft 501 located on the front side of the frame 3.

[0029] Specifically, under normal power generation conditions, the drive motor 701, which is fixedly installed on the top of the mounting plate 601, has a drive gear 702 fixedly connected to one end of its output shaft. The drive gear 702 is meshed with a driven gear 703 at its top. One end of the driven gear 703 is fixedly connected to one end of the fixed shaft 501 located on the front side of the frame 3. This allows the drive motor 701 to drive the frame 3 to shift left and right through the drive gear 702 and the driven gear 703. Then, according to a preset program or light feedback, the photovoltaic module 4 is slowly tilted, so that the incident angle of the oblique sunlight during the morning and evening hours is closer to vertical, which can effectively improve the power generation efficiency during low light periods.

[0030] In Example 3, based on the above examples, a disengagement and return component 6 is provided on the top of the housing 1.

[0031] Furthermore, the detachment and return component 6 includes a mounting plate 601 located on the front side of the frame 3. The two ends of the mounting plate 601 are provided with connecting grooves 602 corresponding to the connecting rods 503, and a horizontal return component is provided inside the connecting grooves 602. The photovoltaic module 4 can fall horizontally when the wind force changes through the horizontal return component.

[0032] Furthermore, the horizontal return component includes: The inner wall of the connecting groove 602 has symmetrically opened grooves 603. A spring 604 is fixedly connected to the inner wall of the groove 603, and a locking post 605 is fixedly connected to the other end of the spring 604. The other end of the locking post 605 is frustoconical. A lifting rod 606 is fixedly connected to the bottom of the mounting plate 601, and the bottom of the lifting rod 606 extends through the top of the box 1 into its interior.

[0033] A mounting plate 607 is fixedly connected to one end of the fixed shaft 501 located on the rear side of the frame 3, and a torsion spring 608 is fixedly connected to one end face of the mounting plate 607 facing the sleeve 502. The other end of the torsion spring 608 is fixedly connected to the outer wall of one side of the sleeve 502.

[0034] In this embodiment, under normal circumstances, the mounting plate 601 has connecting grooves 602 at both ends corresponding to the connecting rods 503, and the inner walls of the connecting grooves 602 have symmetrical grooves 603. The inner walls of the grooves 603 are fixedly connected to springs 604, and the other end of the springs 604 is fixedly connected to a locking post 605. The other end of the locking post 605 is frustoconical. Thus, the mounting plate 601 can be fixed to the outer walls of the two connecting rods 503 located on the front side of the frame 3 through the cooperation of the connecting grooves 602 and the locking post 605, thereby supporting the drive motor 701 and ensuring stable transmission between the drive gear 702 and the driven gear 703.

[0035] Furthermore, when the photovoltaic module 4 descends due to excessive wind force, the separation of the two connecting rods 503 compresses the locking post 605, causing it to contract. At this point, the mounting plate 601 separates from the connecting rods 503. A lifting rod 606 is then fixedly connected to the bottom of the mounting plate 601, and its bottom extends through the top of the housing 1 into its interior. With the assistance of the lifting rod 606, the module descends normally. During this time, the driving gear 702 and the driven gear 703 disengage. A mounting plate 607 is fixedly connected to one end of the fixed shaft 501 located on the rear side of the frame 3. A torsion spring 608 is fixedly connected to one end of the mounting plate 607 facing the sleeve 502. The other end of the torsion spring 608 is fixedly connected to the outer wall of one side of the sleeve 502. Thus, the torsion spring 608 can correct the offset angle of the photovoltaic module 4 to the horizontal position, avoid tilting and falling and causing bumps, and ensure that the photovoltaic module 4 is smoothly and without jamming completely sunk into the top space of the box 1, thereby helping to ensure the stability of the device.

[0036] The working principle of this invention is as follows: When there is no wind or the wind speed is lower than the set threshold, the snap-fit ​​block 515 at the bottom of the support base 505 is firmly embedded in the snap-fit ​​groove 516 at the top of the housing 1 under the downward thrust of multiple springs 517. At this time, the support base 505 cannot move horizontally relative to the housing 1. The connecting rod 503, sleeve 502 and fixed shaft 501 form a rigid triangular support structure, which stably lifts the frame 3 and photovoltaic module 4 above the top of the housing 1. At the same time, the mounting plate 601 in the return component 6 is disengaged and locked onto the outer wall of the two front connecting rods 503 through the connecting groove 602 and the frustum-shaped end of the snap-fit ​​post 605. This ensures that the drive motor 701, the active gear 702 and the driven gear 703 maintain precise meshing. The entire system is in a rigid locked state and can withstand normal wind pressure and its own weight, ensuring the structural stability during normal power generation.

[0037] When encountering a weak wind, the horizontal wind pressure acts on the surface of the large photovoltaic module 4, generating a horizontal thrust. This thrust is transmitted sequentially through the frame 3, the fixed shaft 501, and the sleeve 502 to the four connecting rods 503, and then downwards to the disc base 504. The connecting column 510 at the bottom of the disc base 504 generates a slight horizontal displacement in the movable hole 511 of the support base 505, thereby stretching the tension spring 513 below the limiting disc 512. The tension spring 513 converts the horizontal displacement into an upward pulling force, which acts on the connecting block 514 and the snap-fit ​​block 515, attempting to pull the snap-fit ​​block 515 out of the snap-fit ​​groove 516.

[0038] During this process, multiple springs 517, which are fixed at equal intervals on the inner wall of the support base 505, actively prevent the locking block 515 from disengaging because their other ends are inclined downwards and connected to the top slope of the connecting block 514. When the tension of the tension spring 513 is less than the compression reaction force of the spring 517, the locking block 515 will not completely disengage, but will be in a critical state of partial disengagement. The impact kinetic energy of the wind is converted into elastic potential energy by the repeatedly compressed spring 517, and is consumed as heat energy through the relative sliding friction between the disc base 504 and the support base 505. This design allows the photovoltaic module 4 to perform low-frequency micro-swaying within a limited range, fundamentally avoiding metal fatigue cracks or fractures caused by wind-induced resonance in traditional rigid welded brackets, and significantly extending the structural life. When the wind weakens during the interval between gusts, the elastic potential energy stored in the spring 517 is released, automatically pressing the locking block 515 back to the bottom of the locking groove 516, restoring the fully locked state.

[0039] When the continuous wind force or gust exceeds the design threshold, the tension of the tension spring 513 generated by the horizontal wind pressure will be greater than the maximum compressive bearing capacity of the second spring 517. At this time, the tension spring 513 will force the snap-fit ​​block 515 to be completely pulled out of the snap-fit ​​groove 516. After the snap-fit ​​block 515 is released, the support base 505 loses the horizontal constraint. Under the gravity of the photovoltaic module 4 and the frame 3, the four connecting rods 503 open outward and slide downward at the same time, and the whole thing descends smoothly.

[0040] During descent, the support base 505 moves horizontally along the slide 506, and the spring 509 on the outer wall of the slide rod 507 is compressed, providing a reverse deceleration force proportional to the descent speed. This ensures that the photovoltaic module 4 lands softly at low speed inside the top space of the housing 1. This action provides a triple protection effect: First, it lowers the overall center of gravity of the photovoltaic module 4 from a high place into the housing 1, significantly reducing the wind tilting moment; second, it uses the side walls of the housing 1 to form a natural shelter, preventing hard objects such as sand, gravel, and branches blown by the wind from impacting the photovoltaic panel glass and solar cells at high speed in the horizontal direction; third, the buffering effect of the spring 509 avoids the rigid impact from causing hidden damage to the glass cover and solar cells, thus achieving damage-free self-protection under extreme weather conditions.

[0041] As the photovoltaic module 4 descends, the disengagement and return component 6 operates synchronously. As the two front connecting rods 503 open outward, their rod walls press against the frustum-shaped end of the locking post 605, forcing the locking post 605 to overcome the thrust of the spring 604 and retract into the groove 603. This causes the mounting plate 601 to automatically separate from the connecting rods 503. The mounting plate 601 falls smoothly under the vertical guidance of the lifting rod 606. The drive gear 702 disengages from the driven gear 703, and the drive motor 701 no longer applies any torque.

[0042] Meanwhile, the torsion spring 608 on the rear fixed shaft 501 comes into play. During the previous light tracking process, the deflection of the frame 3 has allowed the torsion spring 608 to store elastic potential energy. The torsion spring 608 releases its potential energy, driving the mounting plate 607 to rotate the fixed shaft 501 in the opposite direction, forcibly returning the frame 3 and photovoltaic module 4 to a horizontal position. After reaching a horizontal position, the photovoltaic module 4 continues to sink in a completely horizontal state, avoiding secondary failures such as the photovoltaic panel edge hitting the side wall of the box, the connecting rod 503 getting stuck, or gear collisions caused by tilting and falling. This ensures that the system remains intact after each strong wind and is easy to reset manually or electrically.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
