Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic support equipment, and more specifically, it relates to a photovoltaic power generation buffer bracket. Background Art

[0002] As a key support structure of a photovoltaic power generation system, a photovoltaic power generation bracket is mainly used to fix and adjust the spatial attitude of photovoltaic modules to achieve efficient light energy capture and conversion. Traditional photovoltaic power generation brackets usually consist of columns, crossbeams, angle adjustment devices and fastening connection components, and their design needs to take into account structural strength, environmental adaptability, installation convenience and cost control.

[0003] A photovoltaic power generation buffer bracket is a bracket structure with a buffering function. It is generally applicable to windy installation scenarios. Through its own buffering effect, it can resist problems such as vibration caused by strong wind weather and can play a good protective role for photovoltaic panels. However, for existing buffer brackets for multiple small photovoltaic panels, their buffering methods generally only set buffer damping components at the connection points. Such buffer damping components can only resist relatively small wind forces. In windy areas of desert plains, if the wind force is strong and lasts for a long time, it may damage the photovoltaic panels, resulting in relatively large losses. Summary of the Invention

[0004] The purpose of the present invention is to provide a photovoltaic power generation buffer bracket to solve the above-mentioned technical problems.

[0005] The present invention solves the above-mentioned existing technical problems through the following technical solutions:

[0006] The present invention provides a photovoltaic power generation buffer bracket, including: a main frame body, a plurality of mounting frames linearly and evenly arranged on the main frame body, and a rotation driving component;

[0007] The top of the main frame body is provided with shrinkage grooves having the same number as the mounting frames, and a wind force monitoring component is arranged on its outer side;

[0008] Each mounting frame is connected to the main frame body through a buffer component. The buffer component includes a support base rotatably mounted on the main frame body and a photovoltaic panel fixing component arranged at the top of the mounting frame. Both sides of the support base are connected to the bottom of the mounting frame through buffer damping components, and its top is hinged to the bottom of the support seat through a universal connection component;

[0009] The photovoltaic panel fixing component includes a connecting frame body rotatable on the top of the mounting frame and a transmission member, and the transmission member makes the connecting frame body rotate synchronously when the mounting frame is folded;

[0010] The rotation driving component is in transmission connection with the rotating ends of all support bases;

[0011] When the wind force value exceeds the threshold, the rotary drive component drives the mounting frame to fold into the contraction groove, and the connecting frame body synchronously folds towards one side of the mounting frame under the driving action of the transmission component, so that the photovoltaic panels are attached end to end in sequence to form a parallel flat panel.

[0012] Preferably, the transmission component includes a driving portion and a transmission portion fixed on the main frame body, and the rotating end of the connecting frame body is in transmission connection with the driving portion through the transmission portion, so that the photovoltaic panel rotates synchronously when the mounting frame folds.

[0013] Preferably, the driving portion is a bevel gear ring arranged on one side of the main frame body, and the transmission portion includes a first rotating rod connected to the rotating end of the connecting frame body and a second rotating rod rotating on the mounting frame. A first bevel gear is fixed on the outer side of the first rotating rod, and second bevel gears are fixed at both ends of the second rotating rod. The two second bevel gears are respectively meshed with the bevel gear ring and the first bevel gear.

[0014] Preferably, a stabilizing member is provided at one end of the second bevel gear close to the bevel gear ring, and a limiting shaft is provided on one side thereof; a first annular groove for sliding in cooperation with the limiting shaft is provided on one side of the bevel gear ring.

[0015] Preferably, an arc-shaped plate is fixed on one side of the main frame body, a second annular groove for sliding in cooperation with the arc-shaped plate is provided on one side of the bevel gear ring, and the bevel gear ring is fixed to the main frame body through a locking screw.

[0016] Preferably, the rotary drive component includes a drive motor and a sprocket group, and the sprocket group is simultaneously connected to the rotating ends of a plurality of support bases, and the drive motor is used to drive the sprocket group to move.

[0017] Preferably, the drive motor is a servo motor, and two are provided, which are respectively connected to the support bases at both ends of the main frame body.

[0018] Preferably, the support base is of an inverted U-shaped structure, a rotating shaft is provided at the bottom thereof, an assembly groove adapted to the rotating shaft is provided at the top of the main frame body, and the rotating shaft is detachably connected to the main frame body through a fixing rod.

[0019] Preferably, the buffer damping component is a spring damper, and its bottom end is detachably connected to the end of the rotating shaft.

[0020] Preferably, the universal connection component includes a hinged ball head and a ball seat, and the top of the support base is connected to the bottom of the photovoltaic panel fixing component through the hinged ball head.

[0021] The beneficial effects of the present invention are as follows:

[0022] This solution uses wind monitoring components to detect environmental wind force in real time. When the wind force is lower than the threshold, the buffer damping component offsets the swing of the mounting frame through elastic deformation to maintain the stability of the photovoltaic panel. When the wind force exceeds the limit, the control system drives the rotary drive component to drive the mounting frame to fold into the contraction groove. At the same time, the bevel gear ring in the transmission part engages with the bevel gear set for transmission, forcing the connecting frame to rotate and fold synchronously, so that each photovoltaic panel fits end to end to form a rigid plane parallel to the main frame, reducing the wind-exposed area and the impact of wind vibration. After folding, the photovoltaic panels support each other to form an overall structure, combined with the contraction groove to adapt to the contour of the mounting frame, which not only reduces the impact of wind load, but also takes into account the stability of daily operation and the wind resistance in extreme weather through dual-mode adaptive switching, thereby improving the reliability and service life of the bracket in harsh environments.

[0032] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0033] Please refer to Figures 1 to 3 , a photovoltaic power generation buffer bracket, comprising: a main frame body 2, a plurality of mounting frames 3 linearly and uniformly arranged on the main frame body 2, and a rotating drive component 5. The number of mounting frames 3 shown in the figure is five, but is not limited to five. The mounting frame 3 is in the shape of a right triangle and is welded with high-strength steel. The top of the main frame body 2 is provided with shrinkage grooves 21 having the same number as the main frame body 2. The shrinkage grooves 21 are adaptively arranged with the mounting frames 3 and serve as the shrinkage and folding areas of the mounting frames 3. A wind monitoring component 6, which is a wind sensor, is arranged outside the main frame body 2 and is connected to the control system of the photovoltaic power station for obtaining the wind force magnitude around the bracket in real time. Each mounting frame 3 is connected to the main frame body 2 through a buffer component 4. The buffer component 4 includes a support base 41 rotatably mounted on the main frame body 2 and a photovoltaic panel fixing component 42 arranged at the top of the mounting frame 3. Both sides of the support base 41 are connected to the bottom of the mounting frame 3 through buffer damping components 43, and its top is hinged to the bottom of the support seat through a universal connection component 44. The buffer damping component 43 is a spring damper. The universal connection component 44 includes a hinged ball head and a ball seat. The top of the support base 41 is connected to the bottom of the photovoltaic panel fixing component 42 through the hinged ball head. The photovoltaic panel fixing component 42 includes a connecting frame body 421 rotatable on the top of the mounting frame 3 and a transmission member. The transmission member includes a driving part fixed to the main frame body 2 and a transmission part. The rotating end of the connecting frame body 421 is in transmission connection with the driving part through the transmission part in cooperation; the rotating drive component 5 is simultaneously in transmission connection with the rotating ends of each support base 41 in cooperation.

[0034] It should be noted that when the above scheme is in use, the wind force around the bracket is monitored in real time through the wind monitoring component 6. When the wind force value is lower than the set threshold, the buffering effect of the buffer damping component 43 itself can be used to maintain the stability of the photovoltaic panel 1 and reduce the shaking of the photovoltaic panel 1; and when the wind force value is greater than the set threshold, the control system starts to control the rotation drive component 5 to start, and drives the plurality of mounting frames 3 to rotate synchronously into the corresponding contraction groove 21 through the rotation drive component 5. At the same time, the connecting frame body 421 is synchronously folded and contracted to one side of the mounting frame 3 under the driving action of the transmission member, so that the plurality of photovoltaic panels 1 are sequentially fitted head to tail to form a flat plate parallel to the top of the main frame body 2, such as Figure 8 As shown, an overall protective form with a continuous support surface is formed. The folded state significantly reduces the impact of wind load by reducing the windward area, and at the same time utilizes the truss effect generated by the mutual support between the panels to enhance the structural stability. This design enables the bracket to maintain the stability of the power generation surface under normal wind force, and quickly convert to a wind-resistant form when encountering strong winds, achieving an effective balance between environmental adaptability and structural safety. In this way, the buffer bracket has two usage modes, which are adapted to wind forces in different situations, thereby improving the adaptability of the buffer bracket and enabling the photovoltaic panel 1 to remain in normal use even in harsh environments.

[0035] Please refer to Figures 3 to 5 In order to realize the function that the photovoltaic panel 1 can synchronously adapt to the folding during the rotation and contraction of the mounting frame 3, the present invention designs a transmission member, specifically: the driving part is a bevel gear ring 422, an arc plate 4211 is fixed on one side of the main frame 2, and a second annular groove 4212 is provided on one side of the bevel gear ring 422 to slide with the arc plate 4211. The arc plate 4211 slides with the second annular groove 4212, so that the bevel gear ring 422 can rotate on one side of the main frame 2. The bevel gear ring 422 is fixed to the main frame 2 by a locking screw 427, and a number of screw holes evenly distributed around the circumference are provided on the bevel gear ring 422. By threading the locking screw 427 with screw holes at different positions, the angle of the connecting frame 421 can be adjusted, and the angle of the photovoltaic panel 1 can be adjusted separately. The transmission part includes a first rotating rod 423 connected to the rotating end of the connecting frame 421 and a second rotating rod 424 rotating on the mounting frame 3. A first bevel gear 425 is fixed to the outer side of the first rotating rod 423, and second bevel gears 426 are fixed at both ends of the second rotating rod 424. The two second bevel gears 426 are respectively meshed with the bevel gear ring 422 and the first bevel gear 425.

[0036] It should be noted that when the above transmission parts are in use, during the process of the rotary drive component 5 driving the mounting frame 3 to rotate, the entire fixed component and the photovoltaic panel 1 rotate together, and the second bevel gear 426 connected to the bevel gear ring 422 starts to rotate along the outer side of the bevel gear ring 422. The first bevel gear 425 starts to rotate under the driving action of the second bevel gear 426, and the connecting frame body 421 rotates synchronously under the driving action of the first rotating rod 423. Finally, the photovoltaic panel 1 can rotate and fold towards the mounting frame 3. When the mounting frame 3 rotates and is clamped into the contraction groove 21, the photovoltaic panel 1 also rotates to be flush with the top of the mounting frame 3. At this time, the photovoltaic panel 1 fits close to the main frame body 2, reducing its height. The parallel state can reduce the wind force, and with the support of multiple photovoltaic panels 1 for each other, the contracted photovoltaic panel 1 can remain stable under the action of the wind force.

[0037] As can be seen from the above, the transmission part realizes multi-stage linkage adjustment through the sliding fit between the bevel gear ring 422 and the arc-shaped plate 4211 of the main frame body 2. Among them, the locking screw 427 is matched with the circumferential screw hole of the bevel gear ring 422 to accurately adjust the initial angle of the connecting frame body 421; during the folding process, when the second bevel gear 426 moves circumferentially along the bevel gear ring 422, it drives the first rotating rod 423 to rotate synchronously through meshing transmission, so that the photovoltaic panel 1 is axially retracted along the track of the contraction groove 21 with the mounting frame 3, and finally forms a compact layout parallel to the main frame body 2. This design, through the meshing transmission between the first bevel gear 425 and the second bevel gear 426 and the mechanical limit of the second annular groove 4212, while ensuring the synchronization of the rotary drive component 5 during linkage folding, utilizes the interlocking support between the plates to enhance the wind resistance stability.

[0038] Please refer to Figures 4 to 5 In order to increase the connection stability between the second rotating rod 424 and the bevel gear ring 422, the present invention further optimizes the above solution. Specifically: a stabilizing member 428 is provided at one end of the second bevel gear 426 close to the bevel gear ring 422, and a limiting shaft 429 is provided on one side thereof; a first annular groove 4210 is provided on one side of the bevel gear ring 422 for sliding cooperation with the limiting shaft 429.

[0039] It should be noted that the working process of the above solution is as follows: when the mounting frame 3 rotates, the second bevel gear 426 starts to rotate along one side of the bevel gear ring 422, and the stabilizing member 428 rotates together with the second rotating rod 424, so that the limiting shaft 429 slides along the first annular groove 4210. Under the limiting action of the stabilizing member 428, the second bevel gear 426 and the bevel gear ring 422 can be stably meshed and move.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 7In order to realize the synchronous rotation and contraction of multiple mounting frames 3 into the corresponding contraction grooves 21, the present invention specifically designs a rotating component, specifically: the rotating driving component 5 includes a driving motor 51 and a sprocket group 52, the sprocket group 52 is connected to the rotating ends of several support bases 41 at the same time, the driving motor 51 is used to move with the sprocket group 52, the driving motor 51 is a servo motor, two of which are arranged in this embodiment, respectively connected to the support bases 41 located at both ends of the main frame 2, and the sprocket group 52 is composed of a chain and a sprocket group 52 with the same number as the mounting frame 3, the sprocket is connected to the support base 41 correspondingly, and the chain drives all the sprockets together, and the rotation of the driving motor 51 can drive the sprocket connected thereto to rotate, and under the transmission action of the chain, multiple support bases 41 and the mounting frame 3 can be rotated together.

[0041] Please refer to Figure 7 The support base 41 is an inverted U-shaped structure, which is adapted to the main frame 2. A rotating shaft 411 is provided at the bottom, and an assembly groove 412 adapted to the rotating shaft 411 is provided at the top of the main frame 2. The outer side of the rotating shaft 411 is detachably connected to the main frame 2 through a fixing rod 413.

[0042] When installing the support base 41, the rotating shaft 411 is directly clamped in the assembly groove 412, and the bottom end of the fixing rod 413 is threadedly fixed to the main frame body 2. The design of the support base 41 not only realizes the stable installation between the mounting frame 3 and the main frame body 2, but also facilitates the rapid assembly of the support base 41, which is convenient for subsequent maintenance and replacement.

[0043] The embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms, which are all within the protection of the present invention.
