Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and in particular to a slope-adaptive support platform for mountain photovoltaic arrays. Background Technology

[0002] With the growth of global energy demand and the improvement of environmental awareness, photovoltaic power generation has been widely used as a clean and renewable energy source. Photovoltaic power generation mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. Mountainous and hilly areas are the main installation areas for photovoltaic power generation equipment.

[0003] In practical applications, due to the complex surfaces of mountainous and hilly terrains, existing flat-ground photovoltaic installation brackets cannot effectively adapt to these surfaces. It is necessary to weld installation brackets on-site to accommodate the undulating terrain, resulting in low installation efficiency. To address this issue, Chinese Patent Publication No. CN223859095U discloses "A Photovoltaic Bracket Adapted to Mountainous Slopes." This bracket, after fixing the support rod to the mountain surface, rotates the first adjusting block to push the support screw upwards, adjusting four sets of fixing plates to the same horizontal plane. This facilitates the rapid installation and fixing of the support beam and mounting plates, making it adaptable to different mountainous and hilly surfaces and effectively improving photovoltaic panel installation efficiency.

[0004] However, in actual use, when photovoltaic arrays are pre-buried in mountainous areas, the angles of the components are often inconsistent due to positional deviations and settlement, which affects the calibration accuracy and reduces power generation efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as inconsistent component angles due to positional deviations and settlement, which affect calibration accuracy and reduce power generation efficiency. Therefore, this invention proposes an adaptive slope mountain photovoltaic array support platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an adaptive slope mountain photovoltaic array support platform, including a base and a support frame, wherein the base is located below the support frame and is covered with a cement layer; The base includes a pre-embedded part and an adaptive part; The adaptive part is connected to the support frame, and the lower end of the adaptive part is provided with a mounting plate. The pre-embedded part is installed on the mounting plate, and the support frame is also provided with a tie rod structure.

[0007] Furthermore, the adaptive portion includes: A support plate is fixedly mounted on the mounting plate. The support plate is connected to a support ring via a universal joint. A lifting platform is mounted on the support ring. The support frame is connected to the lifting platform.

[0008] Furthermore, the gimbal unit includes: A support frame is fixedly mounted on the support ring and the support plate. A connecting unit is provided between the support ring and the support plate, and both ends of the connecting unit are rotatably connected to the support frame.

[0009] Furthermore, the connecting unit consists of a support rod and hinge seats rotatably connected to its two ends. The hinge seats are rotatably connected to the support frame. A motor that is poweredly connected to the hinge seats is installed on the support frame. An angle sensor is installed on the support ring.

[0010] Furthermore, a sleeve is fixedly installed on the support ring, and a plug rod that is movably inserted into the sleeve is fixedly installed on the lifting platform. A support frame and a hinge seat are provided in the middle of both the lifting platform and the support plate, and a linear motor is rotatably connected between the two hinge seats.

[0011] Furthermore, the pre-embedded portion includes: A connecting component is fixedly mounted on the mounting plate, and a pre-embedded part is provided below the connecting component.

[0012] Furthermore, the connection component includes A connecting column is fixedly installed on the mounting plate. A spherical cover is integrally formed on the connecting column. The spherical cover has an opening. A ball is rotatably arranged inside the spherical cover. A fixing column is fixedly installed on the ball. The fixing column passes through the opening and is connected to the embedded part.

[0013] Furthermore, the connecting column has a threaded hole that communicates with the interior of the spherical cover. A positioning element is threaded into the threaded hole, and the lower end of the positioning element contacts the ball.

[0014] Furthermore, the support frame includes a rod body and an extension rod, both of which are provided with a support plate for mounting photovoltaic modules, and the tie rod structure is provided on the rod body.

[0015] Furthermore, the pull rod structure includes a pull rod, a connecting shaft is fixedly mounted on the rod body, one end of the pull rod is rotatably connected to the connecting shaft, and a pre-embedded part is installed at the end of the pull rod away from the connecting shaft.

[0016] The adaptive slope mountain photovoltaic array support platform proposed in this invention has the following advantages: In this invention, by combining the universal unit in the adaptive part with the lifting platform and the sleeve insertion rod structure, the tilt angle can be detected in real time and the support ring angle can be adjusted by the motor drive, so that the lifting platform drives the support frame to adapt to the slope change. The linear motor in the middle of the lifting platform and the support plate further fine-tunes the angle to ensure that the photovoltaic module always maintains the optimal tilt angle, effectively offsetting the pre-embedded deviation and settlement effect, and avoiding uneven photovoltaic array modules. Secondly, in this invention, by connecting the components and the embedded parts, the spherical beads inside the spherical cover allow the fixed column to rotate within a certain range, changing the embedding angle of the embedded parts, thereby avoiding areas unfavorable for construction, and enhancing the overall resistance to deformation through the tie rod structure of the support frame.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-6 An adaptive slope mountain photovoltaic array support platform includes a base 1 and a support frame 2, wherein the base 1 is disposed below the support frame 2 and is covered with a cement layer 3; The base 1 includes a pre-embedded part 4 and an adaptive part 5; The adaptive part 5 is connected to the support frame 2. The lower end of the adaptive part 5 is provided with a mounting plate 6. The pre-embedded part 4 is installed on the mounting plate 6. The support frame 2 is also provided with a tie rod structure 7.

[0021] In this invention, the pre-embedded part 4 is first placed in the installation pit on the hillside. Due to the complex mountainous terrain, there are positional deviations and slope undulations in each pit, making manual leveling extremely difficult and inaccurate. Therefore, before pouring cement, the spatial position and angle of the support frame 2 are automatically changed by the adaptive part 5, so that the support frames 2 of multiple photovoltaic arrays reach a consistent positional reference. After adjustment, the cement layer 3 is poured into the pit to completely solidify and seal the entire base 1, including the adaptive part 5 and the pre-embedded part 4, transforming it into a high-strength rigid foundation. At this time, the base 1 loses its mobility, and the subsequent tracking and angle adjustment of the photovoltaic modules is completed by the existing adjustment mechanism such as the photovoltaic tracker installed on the support frame 2.

[0022] Furthermore, in this embodiment, the adaptive portion 5 includes: A support plate 51 is fixedly installed on the mounting plate 6. The support plate 51 is connected to a support ring 53 through a universal unit 52. A lifting platform 54 is provided on the support ring 53. The support frame 2 is connected to the lifting platform 54. Specifically, the support plate 51 is fixed to the mounting plate 6 and connected to the support ring 53 through the universal unit 52. The lifting platform 54 is set on the support ring 53, and the support frame 2 is connected to the lifting platform 54, providing the support frame 2 with multi-angle adjustment capability.

[0023] Furthermore, in this embodiment, the universal unit 52 includes: A support frame 531 is fixedly mounted on the support ring 53 and the support plate 51. A connecting unit 532 is provided between the support ring 53 and the support plate 51. Both ends of the connecting unit 532 are rotatably connected to the support frame 531. Specifically, the support frame 531 is fixed to the support ring 53 and the support plate 51, and the connecting unit 532 connects the two, with both ends rotatably connected to the support frame 531; thus enabling the support ring 53 to rotate in multiple directions relative to the support plate 51.

[0024] It should be noted that, in this embodiment, the connecting unit 532 consists of a support rod 533 and a hinge seat 534 rotatably connected to both ends. The hinge seat 534 is rotatably connected to the support frame 531. A motor 535 that is poweredly connected to the hinge seat 534 is installed on the support frame 531. An angle sensor is installed on the support ring 53. Specifically, before pouring the cement layer 3, the two ends of the support rod 533 are rotatably connected to the support frame 531 through the hinge seat 534. The motor 535 drives the hinge seat 534, and the tilt sensor detects the angle to realize angle adjustment and real-time monitoring. Both the motor 535 and the tilt sensor are connected to an external controller.

[0025] In this embodiment, a sleeve is fixedly provided on the support ring 53, and a plug rod 55 that is movably inserted into the sleeve is fixedly provided on the lifting platform 54. A support frame 531 and a hinge seat 534 are provided in the middle of both the lifting platform 54 and the support plate 51. A linear motor 56 is rotatably connected between the two hinge seats 534. Specifically, the sleeve is fixed to the support ring 53, and the insertion rod 55 is movably inserted into the sleeve to guide the lifting platform 54 and prevent it from shifting horizontally. The lifting platform 54 and the support plate 51 are provided with a support frame 531 and a hinge seat 534 in the middle. The linear motor 56 is connected to the two hinge seats 534. Before the concrete is poured and cured, the linear motor 56 extends or shortens to drive the lifting platform 54 to rise and fall relative to the support plate 51. With the help of the universal unit 52, it can achieve precise micro-adjustment of multiple degrees of freedom to ensure that the support frame 2 reaches the perfect installation tilt angle. After the micro-adjustment is completed, it is locked by the cement curing.

[0026] Furthermore, in this embodiment, the pre-embedded portion 4 includes: A connecting component 41 is fixedly installed on the mounting plate 6, and a pre-embedded part 42 is provided below the connecting component 41 to realize the pre-embedded fixing of the base 1 and the pre-embedded angle adjustment.

[0027] Specifically, in this embodiment, the connection component 41 includes: A connecting column 411 is fixedly installed on the mounting plate 6. A spherical cover 412 is integrally formed on the connecting column 411. The spherical cover 412 has an opening. A ball bead 413 is rotatably installed inside the spherical cover 412. A fixing column 414 is fixedly installed on the ball bead 413. The fixing column 414 passes through the opening and is connected to the embedded part 42, allowing the embedded part 42 to rotate within a certain range to adapt to different embedment angles.

[0028] In detail, in this embodiment, the connecting column 411 is provided with a threaded hole, which communicates with the interior of the spherical cover 412. A positioning member 415 is threadedly connected to the threaded hole. The lower end of the positioning member 415 contacts the ball 413. The positioning member 415 limits and fixes the adjusted ball 413 to maintain the embedding angle of the embedded part 42.

[0029] In this embodiment, the support frame 2 includes a rod 21 and an extension rod 22. Both the rod 21 and the extension rod 22 are provided with a support plate 23 for mounting photovoltaic modules. The support plate 23 provides an installation platform for the photovoltaic modules. The angle between the support plate 23 and the photovoltaic modules is adjustable. The specific adjustment structure is a conventional and mature technology in the field, such as a photovoltaic tracker, which will not be described in detail here. The tie rod structure 7 is provided on the rod 21 to provide an installation platform for the photovoltaic modules and enhance the overall structural strength.

[0030] More specifically, in this embodiment, the tie rod structure 7 includes a tie rod 71, a connecting shaft 72 is fixedly provided on the rod body 21, one end of the tie rod 71 is rotatably connected to the connecting shaft 72, and a pre-embedded part 42 is installed at the end of the tie rod 71 away from the connecting shaft 72 to enhance the deformation resistance of the support frame 2 and adapt to the mountainous environment.

[0031] Working method: During operation, the pre-embedded part 4 is placed in the pit on the hillside. The ball bearing 413 of the connecting component 41 is rotated to adapt to the undulation of the pit bottom and is initially fixed. Before pouring the cement layer 3, the tilt sensor detects the tilt data and feeds it back to the controller. The controller drives the motor 535 to drive the universal unit 52 to deflect in multiple directions. At the same time, the linear motor drives the lifting platform 54 to make pitch fine adjustments, thereby automatically eliminating position deviations and making each support frame 2 reach the installation benchmark with consistent height. After automatic leveling is completed, the cement layer 3 is poured into the pit to completely seal and solidify the entire base 1.
