Description

Technical Field

[0001] This invention relates to the field of solar panel support technology, and more specifically to a solar panel rotating support. Background Technology

[0002] Solar power generation is the process of converting solar energy into electrical energy. It mainly includes two categories: photovoltaic power generation and solar thermal power generation. In photovoltaic power generation, solar panels (also known as photovoltaic panels) are required. In order to achieve optimal solar irradiance reception, support structures are usually used to tilt the solar panels at a fixed optimal angle according to the current latitude (for example, in Nanjing, the tilt angle is kept at 32 degrees). However, this fixed-tilt installation method can only adapt to the solar altitude angle during a certain period (such as the annual average) or a specific season, and cannot cope with the huge changes in azimuth and altitude angles caused by the sun rising in the east and setting in the west throughout the day. Therefore, most of the time, sunlight does not strike the solar panels perpendicularly, resulting in reduced solar irradiance and suboptimal power generation efficiency.

[0003] To improve energy capture efficiency, automatic solar tracking systems (also known as "sun tracking systems") have emerged. However, existing solar tracking brackets mainly use single-axis trackers. Single-axis trackers typically rotate only around one axis (usually the north-south polar axis or the east-west horizontal axis) to track the sun's diurnal motion trajectory. The structure is relatively simple and the cost is low, but it cannot simultaneously optimize the tracking of the sun's altitude angle, resulting in limited overall gains throughout the year. However, the current mainstream method usually uses an independent motor driven under each mounting bracket, combined with a complex gear, linkage or push rod mechanism to achieve rotation. This design has some significant drawbacks: firstly, its mechanical structure is relatively complex, resulting in high manufacturing and maintenance costs; secondly, the coordination and control requirements of multi-point independent drive are high, and the system reliability faces challenges.

[0004] Therefore, how to simplify the structural design of the tracking bracket, reduce manufacturing costs and maintenance difficulty while ensuring efficient and reliable solar tracking functions has become a technical problem that urgently needs to be solved in this field. In order to solve the above problems, this invention provides a solar rotating bracket. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a solar rotating support that can automatically and reliably drive the mounting frame to rotate in one direction throughout the day, following the sunrise and sunset of the sun, thereby tracking the sun's azimuth angle and improving power generation efficiency. Furthermore, it achieves the above functions through a simplified and robust tension drive structure, effectively reducing the complexity and cost of system manufacturing and maintenance.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a solar rotating bracket, comprising: support; Multiple mounting brackets are rotatably mounted on a support for mounting solar panels, and the mounting brackets are provided at an angle to the horizontal plane; The tensioning assembly is located below both ends of the mounting frame and is used to adjust the height of both ends of the mounting frame, thereby adjusting the angle of the mounting frame; A locking mechanism, which is installed inside the mounting frame and is triggered by the tensioning assembly.

[0007] Preferably, the support includes: A first support rod and multiple second support rods, wherein the height of the second support rod is greater than the height of the first support rod; Multiple fixed shafts, with the mounting bracket rotatably sleeved on the fixed shafts; A fixed shaft is fixedly installed between the first support rod and the second support rod, and a fixed shaft is also fixedly installed between two adjacent second support rods, and the multiple fixed shafts are parallel to each other.

[0008] Preferably, the tensioning assembly includes two sets of take-up and release mechanisms, and the two sets of take-up and release mechanisms are symmetrically distributed with respect to the axis of the fixed shaft. The take-up and release mechanism includes: Multiple lower fixed pulleys are fixedly installed on a bracket and fixedly connected to a support rod. Multiple upper fixed pulleys are fixedly installed on the lower side of the mounting frame; An electric winch, which is mounted on a support rod; A tension sensor, which is mounted on the lower side of a corresponding mounting bracket; A steel wire rope, one end of which is fixedly connected to an electric winch, and the other end of which passes sequentially around multiple lower fixed pulleys and multiple upper fixed pulleys and is fixedly connected to a tension sensor. In this system, the two electric winches in the two sets of take-up and release mechanisms start and stop synchronously, but rotate in opposite directions.

[0009] Preferably, the upper fixed pulley is rotatably mounted with a slider via shafts fixedly connected to both sides. The slider is slidably mounted in a groove provided on the side wall of the mounting base. The mounting base is fixedly connected to the mounting frame. A first spring is connected between the upper end of the groove wall and the corresponding slider. The first spring has an elastic force that pulls the slider upward.

[0010] Preferably, the locking mechanism is installed inside the mounting base, the upper end of the locking mechanism passes through the corresponding mounting base and mounting bracket and abuts against the locking rod that is slidably installed inside the mounting bracket, and the end of the locking rod away from the corresponding locking mechanism passes through the mounting bracket and fits against the fixed shaft.

[0011] Preferably, the locking mechanism further includes an arc-shaped spring plate, which is mounted inside the mounting base by a second spring and located above the corresponding upper fixed pulley, with the opening of the arc-shaped spring plate facing downwards; Two abutting rods are fixedly installed at both ends of the arc-shaped spring plate and slidably installed on the mounting base. The lower ends of the two abutting rods are wedge-shaped and folded towards each other. A top rod is fixedly installed on the arch of the arc-shaped spring plate, and the upper end of the top rod passes through the corresponding mounting seat and mounting bracket and abuts against the locking rod that is slidably installed inside the mounting bracket.

[0012] Preferably, the end of the locking rod near the fixed shaft is wedge-shaped, and the fixed shaft is provided with a groove that matches the locking rod.

[0013] Preferably, each of the second support rods is also vertically provided with an electric lifting column for adjusting the tilt angle of the mounting frame. The output end of the electric lifting column is connected to the mounting frame with a universal joint bearing for realizing the left-right and up-down tilt adjustment of the solar panel. A universal joint bearing is also connected to the top of the first support rod, and the first support rod is connected to the mounting bracket through the universal joint bearing.

[0014] The locking mechanism also includes a brake electric winch and another set of steel wire ropes driven by the brake electric winch. One end of the steel wire ropes is connected to the winding and releasing roller of the brake electric winch, and the other end passes through a fixed pulley set below the mounting frame. A second tension sensor is connected to the tail end of the steel wire ropes. The second tension sensor monitors the tension of the steel wire ropes by being fixed to the ground or a bracket.

[0015] At both ends of the fixed shaft below the mounting frame, electro-hydraulic brake discs are respectively connected to the connection areas of the first support rod and the second support rod. When the electric winch is running, the electro-hydraulic brake discs are released, and when the electric winch stops running, the electro-hydraulic brake discs are tightened to lock the mounting frame.

[0016] Preferably, the bracket is provided with a mounting arm, the mounting arm is provided with a touch switch, and the bracket is also provided with a wind speed sensor.

[0017] Preferably, both ends of the mounting bracket are equipped with sunlight sensors.

[0018] The beneficial effects of this invention are as follows: 1. This technical solution utilizes two symmetrically arranged retraction mechanisms working in tandem to drive the mounting frame to rotate smoothly and precisely around a fixed axis, achieving automatic tracking of the solar azimuth angle. This ensures the solar panels remain oriented towards the sun throughout the day, effectively increasing the amount of direct solar irradiance received and thus significantly improving power generation efficiency. Furthermore, this solution combines an independently adjustable electric lifting column with a universal joint bearing, allowing the tilt angle of the mounting frame to be adjusted according to the season or instructions, achieving a composite tracking mode of "single-axis rotation + adjustable tilt angle." This mode partially compensates for changes in the solar altitude angle without excessively increasing system complexity, achieving a higher overall annual power generation gain compared to traditional fixed single-axis tracking systems.

[0019] 2. This invention innovatively adopts a tensioning drive system composed of a central electric winch, wire rope, and pulley block, replacing the multiple motors, precision gearboxes, and complex linkage mechanisms that are dispersed in traditional tracking supports. The design of this scheme has outstanding economy and practicality. This scheme requires only two electric winches as the main power source for a single row of installation frames, which greatly simplifies the mechanical structure and reduces material and processing costs. The wire rope transmission system has relatively relaxed requirements for installation accuracy, and the on-site construction speed is fast, reducing installation costs and technical requirements. Daily maintenance is mainly carried out on a few electric winches and wire ropes, without the need for frequent calibration or replacement of widely distributed precision transmission components. The workload of operation and maintenance is small, the cost is low, and the operability is strong.

[0020] 3. This solution is based on a distributed control scheme using radio communication, which allows for the deployment of a small number of sensors and control units at intervals in a large photovoltaic power plant, thereby enabling the synchronous operation of a large area of ​​support structures, greatly saving the cost of laying control cables and reducing system complexity.

[0021] 4. To address the safety risks of tracking brackets under harsh conditions such as strong winds and drive failure, this invention integrates a complete protection mechanism from early warning and braking to emergency locking, resulting in significantly superior system safety and reliability compared to traditional designs. This solution uses a wind speed sensor to monitor in real time. When the wind speed exceeds the limit, the system can automatically command the electric winch to stop working and immediately trigger the electro-hydraulic brake disc to lock the fixed shaft, effectively preventing the mounting frame from swaying under wind load.

[0022] 5. In the event of an extreme failure such as wire rope breakage, the system automatically triggers protection through pure mechanical linkage. The use of an arc-shaped spring plate, a clamping rod, and a push rod provides emergency protection in case of wire rope breakage. When the wire rope breaks, the upper fixed pulley moves upward under the action of the first spring, pushing the clamping rod and the arc-shaped spring plate, which in turn drives the push rod to quickly wed the locking rod into the slot of the fixed shaft. This process requires no electricity or signal triggering, is rapid and absolutely reliable, and can instantly achieve rigid locking of the mounting frame and support, preventing uncontrolled rotation and collision. Simultaneously, the broken wire rope is pressed and fixed by the clamping rod, preventing it from swinging and hitting the battery panel, thus achieving dual protection of "structural locking" and "wire rope constraint."

[0042] 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.

[0043] This invention provides a solar-powered rotating support, such as... Figures 1 to 17 As shown.

[0044] Example 1: A solar panel rotating support includes a support frame installed on the ground at a designated location (fixed at the designated location by piling, the location being determined by prior measurements of the array distribution of solar panels). The support frame includes a first support rod 2 and multiple second support rods 3, wherein the height of the second support rods 3 is higher than that of the first support rod 2. A fixed shaft 4 is fixedly installed between the first support rod 2 and its adjacent second support rod 3, and a fixed shaft 4 is also fixedly installed between two adjacent second support rods 3. The multiple fixed shafts 4 are parallel to each other, and a mounting frame 1 is rotatably sleeved on the fixed shaft 4. The mounting frame 1 is used to install solar panels, and the mounting frame 1 forms an angle with the horizontal plane (this angle can be adjusted according to the latitude of the specific location, for example, in Nanjing, the tilt angle is maintained at 32 degrees, thereby improving the power generation efficiency).

[0045] Tensioning components are provided at the bottom of both ends of the mounting frame 1. The tensioning components are used to adjust the height of both ends of the mounting frame 1, thereby causing the mounting frame 1 to rotate around the corresponding fixed axis 4. Adjusting the angle of the mounting frame 1 allows it to rotate according to the angle of the sun throughout the day, ensuring that the sunlight is perpendicular to the solar panels on the mounting frame 1, thus ensuring the efficiency of power generation.

[0046] The tensioning assembly includes two sets of take-up and release mechanisms, which are symmetrically distributed on both sides of the axis of the fixed shaft 4. The take-up and release mechanism includes multiple lower fixed pulleys 5, multiple upper fixed pulleys 6, an electric winch 7, and a tension sensor 8. Among them, multiple lower fixed pulleys 5 and multiple upper fixed pulleys 6 are distributed alternately, and the lower fixed pulleys 5 are fixedly installed on the support rod, the support rod is fixedly connected to the bracket, and the multiple upper fixed pulleys 6 are fixedly installed on the lower side of the mounting frame 1.

[0047] The electric winch 7 is installed on the corresponding support rod, and the tension sensor 8 is installed on the corresponding mounting bracket 1. The electric winch 7 contains a steel wire rope 9. One end of the steel wire rope 9 is fixedly connected to the mounting bracket 1, and the other end passes through the lower fixed pulley 5 and the upper fixed pulley 6 in sequence before being connected to the tension sensor 8.

[0048] In this technical solution, fixed pulleys 6 are installed on the solar panel fixing brackets set on the first support rod 2 and the second support rod 3. The solution uses an electric winch 7 to tighten the steel wire rope 9 wound on the fixed pulleys 6, thereby fixing the solar panel and preventing it from swaying in the wind. When the tensioning component is started, when the solar panel needs to rotate, one side of the electric winch 7 tightens while the other side of the electric winch 7 relaxes (one rotates forward and the other in reverse) in a synchronized action. The electric winches 7 in the two sets of winding and unwinding mechanisms rotate in opposite directions synchronously. The angle is adjusted by controlling the height difference between the two ends of the mounting bracket 1 of the two steel wire ropes 9. When the solar panel rotates to be perpendicular to the sunlight, the reverse electric winch 7 stops moving, while the other forward-rotating electric winch 7 continues moving until the tension sensor 8 reaches the set tension value, at which point the electric winch stops moving, ensuring the tension on the steel wire rope 9, ensuring the steel wire rope 9 is tightened, and ensuring that the solar panel does not sway in the wind.

[0049] In this technical solution, each second support rod 3 is also vertically provided with an electric lifting column 26 for adjusting the tilt angle of the mounting frame 1. The output end of the electric lifting column 26 is connected to the mounting frame 1 with a universal joint bearing 27 for realizing the left and right and up and down tilt adjustment of the solar panel. The top of the first support rod 2 is also connected to a universal joint bearing 27. The first support rod 2 is connected to the mounting frame 1 through the universal joint bearing 27, which further realizes the degree of freedom of the mounting frame 1 to swing.

[0050] Example 2: Based on Embodiment 1, in order to prevent the mounting frame 1 from deflecting when the wire rope 9 breaks, which would damage the solar power panels installed on it, a locking mechanism is provided inside the mounting frame 1. The locking mechanism can press against the fixed shaft 4 when the wire rope 9 breaks, so that the angle of the mounting frame 1 is fixed.

[0051] To ensure a stable triggering of the locking mechanism when the wire rope 9 breaks, sliders 10 are rotatably mounted on both sides of the upper fixed pulley 6. The sliders 10 are rotatably connected to shafts fixedly mounted on the side of the upper fixed pulley 6. The sliders 10 are slidably mounted in a groove 12 provided on the side wall of the mounting base 11. The mounting base 11 is fixedly connected to the mounting frame 1. A first spring 13 is provided between the slider 10 and the top wall of the groove 12. The first spring 13 has an elastic force that pulls the first spring 13 upward. When the wire rope 9 breaks, the upper fixed pulley 6 loses its tension, and the slider 10 moves upward under the tension of the first spring 13, thereby triggering the locking mechanism.

[0052] The locking mechanism is installed on the mounting base 11. The upper end of the locking mechanism passes through the corresponding mounting base 11 and mounting bracket 1 and abuts against the locking rod 15 which is slidably installed inside the mounting bracket 1. The end of the locking rod 15 away from the corresponding locking mechanism passes through the mounting bracket 1 and is in contact with the fixed shaft 4.

[0053] The locking mechanism includes: an arc-shaped spring plate 18 with its opening facing downwards. The arch of the arc-shaped spring plate 18 is mounted inside the mounting base 11 via a second spring 19 and is located above the upper fixed pulley 6. Both ends of the arc-shaped spring plate 18 are fixedly connected to abutment rods 20. The two abutment rods 20 are slidably mounted on the mounting base 11. The arch of the arc-shaped spring plate 18 is fixedly connected to a top rod 21. The upper end of the top rod 21 passes through the corresponding mounting base 11 and mounting frame 1 and abuts against the locking rod 15 slidably mounted inside the mounting frame 1. The lower ends of the two abutment rods 20 are both wedge-shaped and folded towards each other.

[0054] When the wire rope 9 breaks, the upper fixed pulley 6 loses tension, and the slider 10 moves upward under the tension of the first spring 13, causing the upper fixed pulley 6 to move the wire rope 9 upward. At this time, the clamping rod 20 will clamp the wire rope 9. As the clamping rod 20 moves upward, it will drive the top rod 21 to rise through the arc-shaped spring plate 18. The top rod 21 pushes the locking rod 15, causing the locking rod 15 to clamp the fixed shaft 4. This can fix the angle of the mounting frame 1 and prevent the mounting frame 1 from rotating unrestrictedly due to the breakage of the wire rope 9, which could cause damage to the solar panels on it due to collision.

[0055] As a further technical solution in the implementation of this technical solution, the locking mechanism also includes a brake electric winch 29 and another set of steel wire ropes 9 driven by the brake electric winch 29. One end of the steel wire rope 9 is connected to the winding and releasing roller of the brake electric winch 29, and the other end passes through the fixed pulley 5 set below the mounting frame 1. The tail end of the steel wire rope 9 is connected to a second tension sensor 30, which monitors the tension of the steel wire rope by being fixed to the ground or the bracket.

[0056] At both ends of the fixed shaft 4 below the mounting frame 1, an electric hydraulic brake disc 28 is respectively connected to the connection area of ​​the first support rod 2 and the second support rod 3. When the electric winch 7 is running, the electric hydraulic brake disc 28 is released and when the electric winch 7 stops running, the electric hydraulic brake disc 28 is tightened and locked to the mounting frame 1.

[0057] When the top rod 21 pushes the locking rod 15, the arc-shaped spring plate 18 is subjected to a reaction force, which causes the two clamping rods 20 to clamp the steel wire rope 9 at an angle. This allows the clamping rods 20 to better fix the steel wire rope 9 and prevent the steel wire rope 9 from being thrown out and colliding with the solar panel, which would cause the solar panel to be damaged by the collision.

[0058] To better lock the angle of the fixed shaft 4, the end of the locking rod 15 near the fixed shaft 4 is made into a wedge shape, and a groove adapted to the locking rod 15 is provided on the fixed shaft 4. When the locking rod 15 is pressed by the top rod 21, the wedge-shaped end of the locking rod 15 will insert into the corresponding groove, thereby locking the angle of the fixed shaft 4. A return spring 24 is installed between the locking rod 15 and the mounting bracket 1, which can reset the locking rod 15 when the top rod 21 no longer presses against the locking rod 15, so that the wedge-shaped end of the locking rod 15 can exit the groove.

[0059] Example 3: Mounting arms 22 are installed on the bracket, that is, mounting arms 22 are fixedly connected to both sides of the first support rod 2 or both sides of the second support rod 3. The two ends of the mounting arms 22 are equipped with touch switches 14. The touch switches 14 are electrically connected to the tensioning component through the control module 23. The setting of the touch switches 14 can limit the maximum rotation angle of the mounting frame 1 (for example, limit the rotation angle of the mounting frame 1 to 270 degrees) to avoid the rotation angle of the mounting frame 1 being too large and affecting the work.

[0060] A wind speed sensor 17 is also installed on the support. The wind speed sensor 17 is electrically connected to the tensioning component through the control module 23. The wind speed sensor 17 can detect the wind speed in real time. When the wind speed exceeds the set threshold (this value can be modified according to the actual use), the control module 23 can control the tensioning component to stop moving, thereby avoiding excessive wind speed, which would cause it to swing with the wind during rotation and damage the support and mounting frame.

[0061] Two solar sensors 16 are installed at both ends of the mounting frame 1. The solar sensors 16 can detect the difference in sunlight exposure at both ends of the mounting frame 1. The solar sensors 16 are electrically connected to the tensioning component through the control module 23. The control module 23 is installed on the support and can collect the difference between the two solar sensors 16. The operator can control the tensioning component to rotate once every certain period of time by inputting the program into the control module 23 in advance, for example, once every 15 minutes, and rotate until the difference between the two solar sensors 16 is zero. This ensures that the sunlight is perpendicular to the solar panel, thereby ensuring the power generation efficiency of the solar panel.

[0062] In the implementation of this technical solution, each row of solar panels only requires two electric winches 7 and one brake electric winch 29. The steel wire rope 9 is tightened and loosened by the simultaneous forward and reverse rotation of the winches, which in turn drives the solar panels fixed on the bracket to rotate. Within a 5-kilometer diameter range, only two solar sensors, one wind speed sensor, two tension sensors, one controller, and one rotation sensor need to be installed. The remaining electric winches can be controlled synchronously via radio communication. In this technical solution, every two solar sensors 16, one wind speed sensor 17, and one control module 23 form a group of electronic control components. These groups are installed at regular intervals (e.g., every 5 kilometers). See the attached instruction manual for details. Figure 14 .

[0063] Staff can remotely send signals to the control module 23, so that when the sun rises each day, the mounting frame 1 can be controlled to rotate the solar panels on it to face east, so that the solar photovoltaic panels are perpendicular to the sunlight.

[0064] This technical solution uses radio communication with the controller to ensure that the solar panels return to the east, facing the sun, and begin rotating every morning at a set time (based on the sunrise time in different locations), ensuring that all solar panels operate synchronously. In actual operation, all electric winches and rotation sensors can be connected to the controller via radio communication.

[0065] In this solution, an angle sensor 25 is also installed on the bracket. The probe of the angle sensor 25 is connected to the corresponding mounting bracket 1. When adjusting the angle of the mounting bracket 1, the angle sensor 25 can determine whether the angle of the mounting bracket 1 has turned to the adjusted angle, thereby monitoring the rotation angle of the solar panel in real time. Based on the feedback rotation angle, it can determine whether the solar rotation mechanism is damaged and issue an alarm signal in time. In case of failure, it is convenient for staff to repair in time.

[0066] The tension sensor 8, sunlight sensor 16, wind speed sensor 17, control module 23, and angle sensor 25 are all existing technologies and are now widely used. Their specific structures and working principles are not the technical features of this invention, so this invention will not elaborate on them. For example, the tension sensor 8 can be a QLS-10 model, the sunlight sensor 16 can be an ALS-PT19-315C model, the wind speed sensor 17 can be a VMS-FSJT model, the control module 23 can be an IoT module, and the angle sensor 25 can be a GTS200 model.

[0067] The electric winch 7, tension sensor 8, sunlight sensor 16, wind speed sensor 17, control module 23, and angle sensor 25 are electrically connected to an external power source via cables.
