Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to an anti-tipping device. Background Technology

[0002] With the increasing popularity of solar energy as a clean energy source, photovoltaic (PV) power generation systems have been widely deployed globally. PV modules, as the core component of the system, are typically installed on large scale on supports in open outdoor areas to maximize sunlight absorption. These support structures that hold the PV modules are the foundation for the safe and stable operation of the entire PV power plant.

[0003] In current technological practices, in order to control costs, save floor space, and facilitate transportation and installation, the design of photovoltaic module support systems often pursues structural simplification, and the coverage area of ​​the bottom support base or support feet is usually designed to be relatively limited. This compact design can meet basic load-bearing requirements under ideal conditions.

[0004] However, when these support structures are installed in windy or geologically challenging environments, their structural shortcomings become apparent. Due to their small support area, the overall center of gravity of the device is high, making it less resistant to overturning moments. Once subjected to strong winds, gusts, or other lateral forces, the device is highly susceptible to swaying or even complete collapse. This not only directly damages the photovoltaic modules but can also trigger a domino effect of damage within the array, resulting in significant economic losses and safety hazards.

[0005] Therefore, this utility model proposes an anti-tipping device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing anti-tipping devices, such as the instability of the overall structure due to the limited area of ​​the support base, making them prone to tipping over under external forces, this utility model aims to provide an anti-tipping device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an anti-tipping device, including: a first fixing plate, a second fixing plate, a bracket, a photovoltaic panel; as well as a support mechanism and a limiting mechanism.

[0008] The support mechanism includes a rotating shaft, gears, racks, a movable plate, a fixed plate, a connecting rod, a telescopic rod, and a support chamber. The limiting mechanism includes a support column, a fixed column, a fixed plate, a movable plate, a damping column, a spring, a connecting column, a connecting plate, a rotating chamber, a pressure plate, and a damping rod.

[0009] Furthermore, fixed plates are fixedly connected to the left and right sides of fixed plate one, and brackets are fixedly connected to the top of the two fixed plates two. A rotating shaft is rotatably connected to the inner wall of fixed plate one, a gear is fixedly connected to the rotating shaft, a rack is meshed with the rotating shaft, a movable plate is fixedly connected to the rack and slidably connected to the inner wall of fixed plate one, a fixed plate three is fixedly connected to the movable plate, a connecting rod is rotatably connected to fixed plate three, a telescopic rod is rotatably connected to the opposite side of the connecting rod and slidably disposed on the inner wall of the support chamber, and the support chamber is rotatably connected to the inner wall of fixed plate two. Simultaneously, a support column is fixedly connected to the top of fixed plate two, a fixed column is fixedly connected to the top of the support column, a fixed plate is fixedly connected to the inner wall of the fixed column, a movable plate is slidably disposed inside the fixed column, and the two ends of a damping column are fixedly connected to the adjacent side of the movable plate and the left and right sides of the fixed plate, respectively. A spring two is sleeved on the outside of the damping column, with its two ends abutting against the fixed plate and the movable plate, respectively. A connecting column is fixedly connected to the opposite side of the movable plate, a connecting plate is rotatably connected to the connecting column, and a connecting plate is fixedly connected to the outside of the rotating chamber. The pressure plate is slidably connected to the inner wall of the rotating chamber, while the two ends of the damping rod are fixedly connected to the bottom end of the pressure plate and the bottom inner wall of the rotating chamber, respectively.

[0010] Preferably, the rack includes two racks that mesh with the front and rear sides of the rotating shaft respectively. These two racks are configured to move horizontally in opposite directions when the rotating shaft rotates. This symmetrical transmission structure makes the unfolding action of the support mechanism on both sides more stable and synchronous.

[0011] Preferably, the support mechanism further includes an auxiliary mechanism, which has a control plate fixedly connected to the top of the rotating shaft and a positioning nut threadedly connected to the inner wall of the control plate. The positioning nut can be detachably threadedly connected to the inner wall of the top of the fixed plate, thereby achieving reliable locking of the rotating shaft position.

[0012] Preferably, the auxiliary mechanism further includes a connecting shaft, which is rotatably connected to the inner wall of the support chamber and fixedly connected to the front and rear inner walls of the two fixed plates, providing a stable and reliable central fulcrum for the rotation of the support chamber.

[0013] Preferably, a spring is sleeved on the outside of the telescopic rod, and the side of the spring is fixedly connected to the outside of the telescopic rod by a movable ring. Both the spring and the movable ring are auxiliary mechanisms. This design utilizes the elasticity of the spring to provide buffering and auxiliary restoring force for the movement of the telescopic rod.

[0014] Preferably, the auxiliary mechanism further includes a rotating plate and a support column, wherein the rotating plate is rotatably connected to one end of the telescopic rod, and the support column is fixedly connected to the inner wall of one side of the telescopic rod.

[0015] Preferably, a groove is provided on the inner wall of the rotating chamber on the adjacent side, and the pressure plate is slidably connected to the inner wall of the rotating chamber through the cooperation of the groove. The clear guiding structure makes the lifting and lowering movement of the pressure plate more precise and stable during the clamping process.

[0016] Preferably, the damping column is configured to extend and retract along its own axis when the moving disk moves. This extension and retraction can effectively absorb and dissipate the impact energy during the movement of the moving disk, thereby playing a key damping and buffering role in the clamping action and preventing damage to the components due to excessive impact force.

[0017] This utility model relates to an anti-tipping device. 1. This utility model solves the problem of insufficient overall stability and easy to tip over under external force caused by the small support surface and thin structure of existing photovoltaic installation devices by setting up a support mechanism that is linked by gears, racks, connecting rods and telescopic rods.

[0018] 2. This utility model solves the problems of poor adaptability of existing clamping devices to photovoltaic panels of different sizes and easy damage to the panels due to rigid impact during the clamping process by setting an adaptive limiting mechanism that integrates damping column, damping rod and spring. The mechanism uses spring to provide continuous clamping force and is buffered by double damping structure. It achieves the technical effect of stable, flexible and adaptive clamping of photovoltaic panels of different specifications, effectively protects the photovoltaic panels and ensures that they are firmly fixed.

[0019] 3. By adding a control plate and a locking structure with a positioning nut to the support mechanism, this utility model solves the problem that the deployable support mechanism is unstable after deployment and is easily retracted due to vibration. It achieves the technical effect of accurately and reliably locking the support mechanism in any working position, ensuring long-term auxiliary support function. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] The embodiment of this application is as follows: Please refer to Figures 1 to 7 This utility model provides an anti-tipping device, which aims to solve the problems of insufficient structural stability of existing photovoltaic panel installation devices, which are prone to tipping over, poor adaptability of the clamping mechanism to photovoltaic panels of different sizes, and lack of buffering during the clamping process.

[0025] like Figure 1 As shown, the anti-tipping device includes a fixed plate 1 as the installation base, and fixed plates 2 respectively fixedly connected to the left and right sides of the fixed plate 1. The top of the two fixed plates 2 are fixedly connected to a bracket 4 for supporting the photovoltaic panel 6. The anti-tipping device also includes a support mechanism 3 for enhancing the overall structural stability, and a limiting mechanism 5 for clamping and fixing the photovoltaic panel 6. The support mechanism 3 is mainly located between the fixed plate 1 and the fixed plate 2, while the limiting mechanism 5 is located at the top of the fixed plate 2 and works in cooperation with the bracket 4.

[0026] Reference Figures 1 to 3The support mechanism 3 includes a rotating shaft 31 rotatably connected to the inner wall of the fixed plate 1. A gear 32 is fixedly connected to the rotating shaft 31. The rotating shaft 31 is also meshed with two racks 33 located at its front and rear sides respectively. When an external power drives the gear 32 to rotate the rotating shaft 31, the two racks 33 will move horizontally in opposite directions. A movable plate 34 is fixedly connected to the opposite side of each rack 33. The movable plate 34 is slidably connected to the inner wall of the fixed plate 1, so that the movable plate 34 can slide stably with the rack 33. A fixed plate 3 is fixedly connected to the opposite side of the movable plate 34. 35. A connecting rod 36 is rotatably connected to the outer side of the fixed plate 35; a telescopic rod 38 is rotatably connected to the outer side of the connecting rod 36. The telescopic rod 38 is slidably disposed on the inner wall of the support chamber 37, and one end of the support chamber 37 is rotatably connected to the inner wall of the fixed plate 2. Thus, when the rack 33 moves, the thrust is transmitted through the linkage of the moving plate 34, the fixed plate 35 and the connecting rod 36, which can drive the telescopic rod 38 to extend and retract within the support chamber 37, and finally drive the support chamber 37 to rotate outward around its connection point with the fixed plate 2, forming an auxiliary support for the entire device.

[0027] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The limiting mechanism 5 includes a support column 51 fixedly connected to the top of the fixed plate 2. The top of the support column 51 is fixedly connected to a fixed column 52, which serves as the core load-bearing component. A fixed plate 53 is fixedly connected to the inner wall of the middle section of the fixed column 52. A movable plate 55 is slidably arranged in the internal space of the fixed column 52. The adjacent side of the movable plate 55 is fixedly connected to the left and right sides of the fixed plate 53 through a damping column 54. The damping column 54 is configured to extend and retract along its own axis when the movable plate 55 moves, so as to provide damping buffer for the movement of the movable plate 55. At the same time, a spring 502 is sleeved on the outside of the damping column 54. The two ends of the spring 502 abut against the surface of the fixed plate 53 and the surface of the movable plate 55, respectively. The elastic potential energy of the spring 502 provides a continuous and recoverable elastic force to the movable plate 55.

[0028] A connecting post 56 is fixedly connected to the opposite side of the movable disk 55, and a connecting plate 57 is rotatably connected to the opposite side of the connecting post 56. The connecting plate 57 is fixedly connected to the outside of the rotating chamber 58. A sliding groove is provided on the inner wall of the adjacent side of the rotating chamber 58. A pressure plate 501 is slidably connected to the inner wall of the rotating chamber 58 through cooperation with the sliding groove. A damping rod 59 is also fixedly connected to the bottom end of the pressure plate 501, and the other end of the damping rod 59 is fixedly connected to the bottom inner wall of the rotating chamber 58. In the assembled state, the pressure plate 501 is located on the bracket 4. Above, when subjected to the force of the photovoltaic panel 6, it can slide smoothly along the groove under the damping buffer provided by the damping rod 59. Through the transmission of the rotating chamber 58, the connecting plate 57 and the connecting column 56, it finally pushes the moving plate 55 to move, thereby compressing or stretching the second spring 502 and causing the damping column 54 to move. This linkage structure that integrates spring force and dual damping (damping rod 59 and damping column 54) ensures that the clamping force on the photovoltaic panel 6 is both stable and continuous, and has a good buffering effect, which greatly improves the reliability and safety of clamping.

[0029] As a preferred embodiment, refer to Figure 1 , Figure 5 and Figure 6 The auxiliary mechanism 39 includes a control plate 396 fixedly connected to the top of the rotating shaft 31, and a positioning nut 397 threadedly connected to the inner wall of the control plate 396. When the support chamber 37 is unfolded to the predetermined position, the control plate 396 can be rotated so that the positioning nut 397 is aligned with the pre-set thread structure on the inner wall of the top of the fixed plate 1 and tightened, thereby detachably fixing the rotation position of the rotating shaft 31 and achieving reliable locking of the unfolded state of the entire support mechanism 3. The support mechanism 3 also includes a connecting shaft 391 rotatably connected to the inner wall of the support chamber 37. The two ends of the connecting shaft 391 are respectively fixedly connected to the front and rear inner walls of the two fixed plates 2. The connecting shaft 391 belongs to the auxiliary mechanism 39, which provides a fixed rotation center for the support chamber 37, ensuring its unfolding... To ensure the stability and structural strength of the telescopic rod 38, a spring 393 is fitted around its exterior. The adjacent side of the spring 393 is fixedly connected to the exterior of the telescopic rod 38 via a movable ring 392. Both the spring 393 and the movable ring 392 are auxiliary mechanisms 39. When the telescopic rod 38 extends or retracts, the spring 393 is correspondingly compressed or stretched, thus providing a buffer and assisting in its return to its original position. A rotating plate 394 is rotatably connected to the adjacent end of the telescopic rod 38, and a support column 395 is fixedly connected to the inner wall of its adjacent side. Both the rotating plate 394 and the support column 395 are auxiliary mechanisms 39. The support column 395 enhances the structural rigidity of the telescopic rod 38, while the rotating plate 394 allows the connecting components to adaptively adjust their angles during movement.

[0030] The sliding connection between the pressure plate 501 and the rotating chamber 58 is achieved by opening a groove on the inner wall of the adjacent side of the rotating chamber 58. The corresponding structure on the pressure plate 501 slides along the groove. This structure limits the movement trajectory of the pressure plate 501, making its movement more stable and precise.

[0031] The implementation principle of this application embodiment is as follows: Fixed plates 2 are fixedly connected to both the left and right sides of fixed plate 1. Brackets 4 are fixedly connected to the top of the two fixed plates 2. The rotating shaft 31 in the support mechanism 3 is rotatably connected to the inner wall of the top of fixed plate 1. First, a rotational force is applied to the gear 32 in the device, causing the gear 32 to start rotating. Since the top of the gear 32 is fixedly connected to the bottom of the rotating shaft 31, and the top of the rotating shaft 31 is rotatably connected to the inner wall of the top of fixed plate 1, and the bottom is slidably connected to the inner wall of the bottom of fixed plate 1 through gear 32, the rotation of gear 32 will synchronously drive the rotating shaft 31 to rotate stably on the inner wall of fixed plate 1. During the rotation of the shaft 31, because its front and rear sides are respectively engaged with two racks 33, the gear 32 will drive the two racks 33 to move horizontally in opposite directions along the inner wall of the fixed plate 1 through the rotation of the shaft 31; and because the opposite sides of the two racks 33 are respectively fixedly connected to the moving plate 34, and the outer side of the moving plate 34 is slidably connected to the inner wall of the fixed plate 1, the movement of the racks 33 will synchronously push the corresponding moving plate 34 to maintain stable sliding in the inner wall of the fixed plate 1.

[0032] As the movable plate 34 slides, the fixed plate 35, which is fixedly connected to the opposite side of the two movable plates 34, will move along with the movable plate 34. The opposite side of the fixed plate 35 is rotatably connected to the connecting rod 36. Therefore, the movement of the fixed plate 35 will generate a thrust on the connecting rod 36, causing the connecting rod 36 to rotate around the connection point with the fixed plate 35. Since the opposite side of the connecting rod 36 is rotatably connected to the outside of the telescopic rod 38, and the outside of the telescopic rod 38 is fixedly connected to the inner wall of the support chamber 37, while the inner wall of the support chamber 37 is rotatably connected to the opposite side of the inner wall of the second fixed plate 2, the rotation of the connecting rod 36 will push the telescopic rod 38 to extend and retract within the inner wall of the support chamber 37, thereby causing the support chamber 37 to unfold around the connection point with the second fixed plate 2. During this process, the opposite side of the inner wall of the support chamber 37 is rotatably connected to the connecting shaft 391 in the auxiliary mechanism 39, and the upper and lower ends of the connecting shaft 391 are fixedly connected to the front and rear inner walls of the two second fixed plates 2. The connecting shaft 391 provides a stable fulcrum for the unfolding of the support chamber 37, ensuring that the support chamber 37 can smoothly rotate and unfold around the connecting shaft 391.

[0033] When the telescopic rod 38 extends or retracts, a spring 393 is sleeved on the outer side of its far side, and a movable ring 392 is fixedly connected to the near side of the spring 393. The inner wall of the movable ring 392 is fixedly connected to the outer side of the far side of the telescopic rod 38. The extension and retraction of the telescopic rod 38 will drive the movable ring 392 to move synchronously, so that the spring 393 will be stretched or compressed according to the extension and retraction state of the telescopic rod 38. The elastic potential energy of the spring 393 provides buffer and auxiliary thrust for the movement of the telescopic rod 38, ensuring the smoothness of the movement of the telescopic rod 38. At the same time, a rotating plate 394 is rotatably connected to the near end of the telescopic rod 38, and a support column 395 is fixedly connected to the inner wall of the near side of the telescopic rod 38. The support column 395 provides support for the internal structure of the telescopic rod 38, and the rotating plate 394 can flexibly adjust its angle during the movement of the telescopic rod 38 to avoid rigid collisions between components. After the support chamber 37 is deployed to the preset auxiliary support position, the control plate 396, which is fixedly connected to the top of the rotating shaft 31, is rotated to make the control plate 396 rotate around the rotating shaft 31 until the positioning nut 397 threaded on the inner wall of the control plate 396 is aligned with the threaded structure on the inner wall of the top of the fixed plate 1. Then, the positioning nut 397 is tightened, and the bottom of the positioning nut 397 is tightly threaded to the inner wall of the top of the fixed plate 1. Thus, the position of the rotating shaft 31 is locked by the cooperation between the positioning nut 397 and the control plate 396, thereby fixing the state of the support chamber 37 and keeping the support chamber 37 in the deployed support posture. Finally, the auxiliary support effect of the entire device is achieved, improving the stability of the photovoltaic module after installation and preventing it from tipping over.

[0034] The top ends of the two fixed plates 2 are respectively fixedly connected to the support columns 51 in the limiting mechanism 5. The basic support of the limiting mechanism 5 is provided by the two support columns 51. The two support columns 51 are respectively fixedly connected to the top ends of the two fixed plates 2. Through the connection between the fixed plates 2 and the overall structure of the device, a stable installation foundation is provided for the entire limiting mechanism 5. The top ends of the support columns 51 are fixedly connected to the fixed columns 52. The fixed columns 52 are the core load-bearing components of the limiting mechanism 5. The fixed plate 53 fixedly connected to the inner wall of the middle section becomes the reference point for the subsequent installation of the damping structure and the elastic structure. When it is necessary to clamp the photovoltaic panel 6, the top of the photovoltaic panel 6 contacts the bottom of the two pressure plates 501. Due to the difference in the number or size of the photovoltaic panels 6, the force exerted on the pressure plates 501 and the required clamping space will change accordingly. At this time, the pressure plates 501 will slide on the inner wall of the adjacent side of the rotating chamber 58 according to the actual state of the photovoltaic panel 6. Because a sliding groove is provided on the adjacent side of the rotating chamber 58, the pressure plates 501 can move flexibly up and down or back and forth along the sliding groove to adapt to the changes in the thickness or width of the photovoltaic panel 6.

[0035] During the sliding process of the pressure plate 501, the two damping rods 59 fixedly connected to the bottom end on opposite sides will move synchronously. The bottom end of the damping rod 59 is fixedly connected to the inner wall of the bottom end of the rotating chamber 58. Through the damping characteristics of the damping rod 59 itself, the sliding speed of the pressure plate 501 can be reduced, avoiding damage to the photovoltaic panel 6 caused by the rapid movement of the pressure plate 501 due to the impact force when the photovoltaic panel 6 is placed. At the same time, it provides stable support for the pressure plate 501, ensuring that it remains stable during the clamping process. A connecting plate 57 is fixedly connected to the outside of the rotating chamber 58. The connecting plate 57 is rotatably connected to the far side of the connecting column 56, while the near side of the connecting column 56 is fixedly connected to the far side of the moving plate 55. When the rotating chamber 58 undergoes a slight adjustment in angle or position due to the force of the pressure plate 501, the connecting plate 57 can rotate around the end of the connecting column 56, causing the connecting column 56 to move synchronously, thereby pushing the moving plate 55 to move in the internal space of the fixed column 52. A damping column 54 is fixedly connected to the near side of the moving plate 55. The near side of the damping column 54 is fixedly connected to the left and right sides of the fixed plate 53. The damping column 54 can extend and retract along its own axis under the push of the moving plate 55, using the damping effect to further buffer the impact force of the moving plate 55, avoiding damage to the components due to rigid collision. At the same time, the extension and retraction of the damping column 54 can adapt to the clamping space adjustment required for photovoltaic panels 6 of different sizes.

[0036] A second spring 502 is also fitted outside the damping column 54. The two ends of the second spring 502 contact the fixed disk 53 and the moving disk 55, respectively. When the moving disk 55 moves away from the fixed disk 53, the second spring 502 is stretched, generating a reverse elastic force that causes the moving disk 55 to tend to return to the fixed disk 53. When the moving disk 55 moves closer to the fixed disk 53, the second spring 502 is compressed, generating a reverse elastic force that limits the excessive movement of the moving disk 55. The elastic force of 02 provides a continuous and adjustable clamping force for the entire clamping structure. The bracket 4 serves as the bottom support for the photovoltaic panel 6 and forms an upper and lower clamping cooperation with the pressure plate 501 of the limiting mechanism 5. Under the synergistic action of the damping rod 59, the damping column 54 and the second spring 502, the pressure plate 501 always fits tightly against the top of the photovoltaic panel 6, ultimately achieving a stable clamping effect for different numbers and sizes of photovoltaic panels 6, preventing the photovoltaic panel 6 from shifting or tipping over during use, and ensuring the normal operation of the photovoltaic module.
