[0034] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1 to 13 :

[0036] A highly stable flexible photovoltaic bracket comprises a first bearing portion 1 for mounting on the ground, and a photovoltaic mounting frame 2 for mounting photovoltaic panels, wherein the first bearing portion 1 comprises a fixing frame 11, a plurality of fixing legs 111 are arranged around the fixing frame 11, a vertical main support frame 12 is arranged at the center of the fixing frame 11, a universal adjustment portion 3 is arranged on the top of the main support frame 12, the main support frame 12 is connected to the photovoltaic mounting frame 2 through the universal adjustment portion 3, and the universal adjustment portion 3 adjusts the inclination angle and direction of the photovoltaic mounting frame 2; a plurality of flexible steel wire ropes 4 are arranged on the first bearing portion 1, and the flexible steel wire ropes 4 are connected to the photovoltaic mounting frame 2; The first bearing part 1 and the photovoltaic mounting frame 2 are connected, and the flexible steel wire rope 4 stably supports the inclination angle of the photovoltaic mounting frame 2. The first bearing part 1 is provided with a tensioning regulator 13 for adjusting the tension of the flexible steel wire rope 4; a plurality of mounting bases 21 are provided at the bottom of the photovoltaic mounting frame 2, and a plurality of wind flow guide plates 5 and an angle locking unit 51 for locking the angle of the wind flow guide plate 5 are rotatably installed in the mounting base 21. The flexible steel wire rope 4 is transmission-connected to the angle locking unit 51, and the tensioning regulator 13 drives the angle locking unit 51 to lock the wind flow guide plate 5 when the flexible steel wire rope 4 is tightened.

[0037] When the present invention is in use, the fixing frame 11 of the first bearing part 1 is installed on the ground through the fixed legs 111 on the circumferential side to achieve stable fixation of the first bearing part 1. The main support frame 12 is vertically set in the center of the fixing frame 11, and the photovoltaic mounting frame 2 is installed on the top of the main support frame 12 through the universal adjustment part 3. Several photovoltaic panels are installed on the upper surface of the photovoltaic mounting frame 2. Then, according to the initial installation requirements, the universal adjustment part 3 makes preliminary adjustments to the tilt angle and direction of the photovoltaic mounting frame 2. As the position of the sun changes throughout the day, the tilt angle and direction of the photovoltaic mounting frame 2 can be adjusted through the universal adjustment part 3 so that the photovoltaic panels can face the sunlight as directly as possible, thereby improving the utilization rate of solar energy. When it is necessary to further stabilize the tilt angle of the photovoltaic mounting frame 2, the tension of the flexible steel wire rope 4 is adjusted through the tensioning regulator 13 to relax the flexible steel wire rope 4. When the flexible steel wire rope 4 is tightened, it can play a stabilizing supporting role for the tilt angle of the photovoltaic mounting frame 2. On the other hand, the flexible steel wire rope 4 is in transmission connection with the angle locking unit 51, which drives the angle locking unit 51 to lock the wind flow guide plate 5. In a windy environment, if the flexible steel wire rope 4 is in a relaxed state, the wind flow guide plate 5 can be affected by the wind and rotate within the mounting base 21. By rotating and adjusting its own angle, it adapts to the wind direction, thereby reducing the impact of the wind on the photovoltaic mounting frame 2. When the flexible steel wire rope 4 is tightened, the angle locking unit 51 locks the angle of the wind flow guide plate 5, keeping it in the appropriate position, further enhancing the stabilization effect on the photovoltaic mounting frame 2 and preventing it from tipping over in harsh environments such as strong winds. In this embodiment, the provision of the universal adjustment part 3 allows the tilt angle and direction of the photovoltaic mounting frame 2 to be flexibly adjusted, and the direction and angle of the photovoltaic panel can be adjusted in real time according to changes in sunlight. This overcomes the shortcomings of traditional photovoltaic brackets that have a single and fixed direction and cannot adjust themselves with sunlight, improves the utilization rate of solar energy, and is more conducive to the storage of solar energy. The first bearing part 1 is stably mounted by a fixed frame 11 and fixed legs 111. A plurality of flexible steel cables 4 are provided to connect the first bearing part 1 and the photovoltaic mounting frame 2. The tension is adjusted by a tensioning regulator 13, which can provide stable support for the photovoltaic mounting frame 2. This greatly improves the stability of the entire device in harsh environments such as wind, effectively preventing the photovoltaic mounting frame 2 and the photovoltaic panels mounted thereon from tipping over or being damaged, and improving the performance and service life of the device. The wind flow guide plate 5 and the angle locking unit 51 are provided within the mounting base 21 at the bottom of the photovoltaic mounting frame 2. In a windy environment, the wind flow guide plate 5 can rotate to adapt to the wind direction and reduce the impact of the wind. When the flexible steel cables 4 are tightened, their angles can be locked, further enhancing the stabilizing effect on the photovoltaic mounting frame 2. Furthermore, the transmission connection between the flexible steel cables 4 and the angle locking unit 51 achieves linkage between the two, improving the automation and stability of the device.

[0038] In order to achieve the purpose of multi-angle adjustment of the photovoltaic installation frame 2, the following features are specifically set:

[0039] A vertically extending shaft cylinder 121 is provided on the main support frame 12, and the universal adjustment part 3 includes a rotating seat 31 coaxially installed on the shaft cylinder 121, and a first rotation driver 32 for driving the rotating seat 31 to rotate around the axis of the shaft cylinder 121; a connecting seat 33 is hingedly installed above the rotating seat 31, and the connecting seat 33 is fixedly connected to the bottom center position of the photovoltaic mounting frame 2, and the rotation axis of the connecting seat 33 is horizontally arranged. The universal adjustment part 3 also includes a second rotation driver 34 for driving the connecting seat 33 to rotate.

[0040] A limiting shaft 311 is coaxially arranged at the bottom of the rotating seat 31, and the limiting shaft 311 is rotatably installed in the shaft cylinder 121. A driven gear 312 is coaxially installed on the limiting shaft 311. The first rotating driver 32 is fixedly installed on the main support frame 12. The rotating axis of the first rotating driver 32 is arranged parallel to the shaft cylinder 121. A first driving gear 321 is coaxially installed on the rotating end of the first rotating driver 32, and the first driving gear 321 is meshed and connected with the driven gear 312.

[0041] A first hinge portion 313 is provided at the top of the rotating seat 31, and a second hinge portion 331 is provided at the bottom of the connecting seat 33. The first hinge portion 313 and the second hinge portion 331 are coaxially rotatably connected. The outer wall of the second hinge portion 331 is provided with teeth and grooves distributed around the axis of the second hinge portion 331. The second rotation driver 34 is fixedly installed on the top of the rotating seat 31. The rotation axis of the second rotation driver 34 is parallel to the axis of the second hinge portion 331. A second driving gear 341 is coaxially installed on the rotation axis of the second rotation driver 34, and the second driving gear 341 is meshed with the teeth and grooves 332.

[0042] In this embodiment, when the tilt angle of the photovoltaic mounting frame 2 needs to be adjusted, the second rotary actuator 34 is activated. The second drive gear 341 on the rotating shaft of the second rotary actuator 34 begins to rotate. Because the second drive gear 341 meshes with the tooth grooves 332 distributed around the axis of the outer wall of the second hinge portion 331, it drives the second hinge portion 331, the connecting seat 33, and the photovoltaic mounting frame 2 to rotate, thereby adjusting the tilt angle of the photovoltaic mounting frame 2. When the direction of the tilt surface of the photovoltaic mounting frame 2 needs to be adjusted, the first rotary actuator 32 is activated. The first drive gear 321 on the rotating end of the first rotary actuator 32 begins to rotate. Because the first drive gear 321 meshes with the driven gear 312 on the limiting shaft 311, the driven gear 312 rotates with the rotation of the first drive gear 321. The limiting shaft 311 is coaxially mounted on the driven gear 312 and rotatably mounted within the shaft barrel 121. Therefore, the limiting shaft 311 drives the rotating seat 311 to rotate about the axis of the shaft barrel 121. Because the connecting base 33 is hingedly mounted above the rotating base 31 and fixedly connected to the center of the bottom of the photovoltaic mounting frame 2, the photovoltaic mounting frame 2 also rotates horizontally, thereby adjusting the tilt of the photovoltaic mounting frame 2. In this embodiment, the first rotating actuator 32 and the second rotating actuator 34 can be servo motors. Through the coordinated operation of the first rotating actuator 32 and the second rotating actuator 34, the photovoltaic mounting frame 2 can be flexibly adjusted at multiple angles, allowing it to better adapt to changes in sunlight and achieve the optimal solar energy reception angle.

[0043] In order to solve the problem of how the flexible steel wire rope 4 supports the photovoltaic installation frame 2 that is rotated to any direction and tilted, thereby reducing the pressure on the working end of the second rotary driver 34, the following features are specifically set:

[0044] The bottom of the photovoltaic mounting frame 2 is provided with a plurality of opposite groups of rope end fixers 22, each group of rope end fixers 22 is respectively fixedly connected to the two ends of a flexible steel wire rope 4, and the connection line of the two opposite rope end fixers 22 is perpendicular to the axis of the second hinge part 331; the main rotating bracket 14 is rotatably mounted on the first bearing part 1, and the main rotating bracket 14 includes a limiting ring 141 and a plurality of mounting beams 142 in the limiting ring 141, and a fixing frame 11 is provided with a fixing frame 11 on the same axis as the shaft cylinder 121 The annular limit frame 112, the limit ring 141 is coaxially rotatably installed in the annular limit frame 112, and the mounting beam 142 is connected to the rotating seat 31 by a number of connecting arms 314; the mounting beam 142 is provided with the same number of fixed pulleys 143 as the rope end fixer 22, and the fixed pulleys 143 are respectively located on both sides of the tensioning adjuster 13, and the axis of the fixed pulley 143 is parallel to the axis of the second hinge part 331, and the flexible steel rope 4 is connected to the rope end fixer 22 through the guidance of the fixed pulley 143.

[0045] In this embodiment, the ends of the flexible steel cable 4 are fixed to the rope end holders 22 at the bottom of the photovoltaic mounting frame 2, which are located opposite each other. Simultaneously, the flexible steel cable 4 passes around the fixed pulleys 143 on the mounting beam 142. The fixed pulleys 143 are located on either side of the tensioning adjuster 13, with their axes parallel to the axis of the second hinge 331. This allows the flexible steel cable 4 to generate tension on the two ends of the photovoltaic mounting frame 2 at the high and low positions. When the first rotary actuator 32 drives the rotating base 31 to rotate about the axis of the shaft cylinder 121, the main rotating bracket 14 rotates synchronously with the photovoltaic mounting frame 2, as the mounting beam 142 and the rotating base 31 are connected by the connecting arm 314, and the limiting ring 141 is coaxially mounted within the annular limiting frame 112. During rotation, the flexible steel cable 4 is always guided by the fixed pulley 143, providing stable support for the photovoltaic mounting frame 2. When the tension of the flexible steel wire rope 4 is locked by the tension regulator 13, the photovoltaic mounting frame 2 tilts to any direction, and the flexible steel wire rope 4 forms a pulling support force on the photovoltaic mounting frame 2 through the guiding effect of the fixed pulley 143. This support force can share part of the gravity of the photovoltaic mounting frame 2 and the lateral force generated by the tilt, thereby reducing the pressure acting on the working end of the second rotary actuator 34 and reducing the load on the second rotary actuator 34. Through the specific layout of the rope end fixer 22 and the guiding setting of the fixed pulley 143, the main rotating bracket 14 is connected to the rotating seat 31 through the connecting arm 314 in this technical solution, ensuring that the main rotating bracket 14 can keep consistent with the rotation of the photovoltaic mounting frame 2, so that no matter what direction and angle the photovoltaic mounting frame 2 rotates to, the flexible steel wire rope 4 can effectively support it.

[0046] In order to achieve the purpose of reducing the tension of the flexible steel rope 4 on the photovoltaic installation frame 2 when adjusting the tilt angle of the photovoltaic installation frame 2, the following features are specifically set:

[0047] The tensioning adjuster 13 is arranged below the main support frame 12, and the tensioning adjuster 13 includes two winding rods 131. The winding rods 131 extend in a horizontal direction parallel to the axis of the second hinged part 331, and all the flexible steel ropes 4 pass through the two winding rods 131; the two ends of the winding rod 131 are fixedly connected by a connecting head 132, and the connecting head 132 is provided with a central axis 133 parallel to the winding rod 131, and the central axis 133 is inserted into a fixed sleeve 144 provided on the mounting beam 142, and a third rotation driver 134 is fixedly installed on the mounting beam 142. The working end of the third rotation driver 134 is transmission-connected to the central axis 133, and the third rotation driver 134 drives the two winding rods 131 to rotate around the axis of the central axis 133 to wind the flexible steel rope 4.

[0048] In this embodiment, the third rotary actuator 134 can be a servo motor fixedly mounted on the mounting beam 142, with its working end in driving connection with the central shaft 133 on the connector 132. Upon activation, the third rotary actuator 134 drives the two winding rods 131 to rotate about the central shaft 133. Because the winding rods 131 extend horizontally parallel to the axis of the second hinged portion 331, and the entire flexible steel wire 4 passes between the two winding rods 131, the rotation of the winding rods 131 winds the flexible steel wire 4 around them. As the winding progresses, the effective length of the flexible steel cord 4 decreases, and the tension on the photovoltaic mount frame 2 increases accordingly. When the tilt angle of the photovoltaic mount frame 2 needs to be adjusted, before activating the first rotary actuator 32 and the second rotary actuator 34 of the universal adjustment unit 3, the third rotary actuator 134 is first activated to rotate in the opposite direction. The winding rod 131 rotates to unwind the flexible steel cord 4, increasing the effective length of the flexible steel cord 4 and reducing the tension on the photovoltaic mount frame 2 accordingly. This reduces the tension of the flexible steel cord 4 on the photovoltaic mount frame 2, allowing the angle adjustment of the photovoltaic mount frame 2 to be performed more smoothly. After the photovoltaic mount frame 2 is adjusted to the appropriate tilt angle, the third rotary actuator 134 is activated again to restore the tension of the flexible steel cord 4 to stably support the photovoltaic mount frame 2. In this embodiment, the third rotary actuator 134 drives the winding rod 131 to wind the flexible steel cord 4, which can effectively reduce the tension of the flexible steel cord 4 on the photovoltaic mount frame 2 when adjusting the tilt angle of the photovoltaic mount frame 2. This can prevent the angle adjustment of the photovoltaic installation frame 2 from being hindered by excessive tension in the flexible steel wire rope 4, making the angle adjustment smoother and improving the efficiency and flexibility of the adjustment.

[0049] In order to achieve the purpose of automatically rotating and adjusting the direction of the wind flow guide plate 5 under the action of wind force, the following features are specifically set:

[0050] A circular mounting cavity 211 is provided in the mounting base 21, and a turntable 212 is coaxially installed in the mounting cavity 211. A shaft 213 is provided at the axis of the turntable 212. The turntable 212 is connected to a horizontal panel 214 provided on the outside of the mounting base 21 through the shaft 213. A plurality of airflow guide plates 5 are arranged at equal intervals on the side of the horizontal panel 214 away from the shaft 213; a plurality of balls 215 are rotatably installed on the side of the turntable 212 that is in contact with the inner wall of the mounting cavity 211.

[0051] When there is wind, the wind will blow toward the wind deflector plate 5. Since the wind deflector plate 5 is mounted on the horizontal panel 214, and the horizontal panel 214 is connected to the turntable 212 via the shaft 213, the force exerted by the wind on the wind deflector plate 5 is transmitted to the turntable 212 via the horizontal panel 214 and the shaft 213. Under the action of the wind, the turntable 212 overcomes the friction between the ball bearings 215 and the inner wall of the mounting cavity 211 and rotates around the axis of the shaft 213. As the turntable 212 rotates, the horizontal panel 214 and the wind deflector plate 5 mounted thereon also rotate accordingly, thereby enabling the wind deflector plate 5 to automatically adjust its direction so that its plate surface is as parallel to the wind direction as possible, thereby reducing the impact of the wind on the photovoltaic mounting frame 2. In this embodiment, by providing structures such as the turntable 212, the shaft 213, and the ball bearings 215, the wind deflector plate 5 can automatically rotate and adjust its direction under the action of wind. This automatic adjustment function does not require human intervention and can adapt to changes in wind direction in real time, effectively reducing the impact of wind on the photovoltaic mounting frame 2, and improving the stability and wind resistance of the photovoltaic support in windy environments.

[0052] In order to achieve the purpose of driving the angle locking unit 51 to lock the angle of the wind flow guide plate 5 when the flexible steel rope 4 is tightened, the following features are specifically set:

[0053] The angle locking unit 51 includes a push rod 511, which is inserted into an insertion hole 216 provided on the mounting base 21 and extending radially along the mounting cavity 211. When the push rod 511 is in contact with the outer wall of the turntable 212, the turntable 212 is restricted from rotating. One end of the push rod 511 located outside the mounting base 21 is fixedly connected to the external frame 512. A spring 513 is sleeved on the push rod 511. The spring 513 elastically connects the outer wall of the mounting base 21 and the external frame 512. The elastic force of the spring 513 causes the push rod 511 to move toward the side away from the turntable 212. Movement; the insertion hole 216 is set on the side of the mounting base 21 away from the connecting seat 33, and a horizontal connecting rod 514 is set at one end of the external frame 512 close to the connecting seat 33. The external frame 512 and the connecting rod 514 are connected by a connecting rope 515. The connecting rope 515 is hung on the hanging rope rod 23 set at the bottom of the photovoltaic mounting frame 2. The flexible steel wire rope 4 passes through the upper side of the connecting rope 515. When the flexible steel wire rope 4 is wound on the winding rod 131, the connecting rod 514 is pulled down to make the top rod 511 move along the insertion hole 216 toward the turntable 212.

[0054] A guide rod 516 extending parallel to the axis of the insertion hole 216 is provided on the external frame 512 . The guide rod 516 is inserted into a guide sleeve 217 provided on the outer wall of the mounting base 21 .

[0055] Friction grooves are provided on the circumference of the turntable 212 .

[0056] In this embodiment, when the photovoltaic mounting frame 2 adjusts its tilt angle, the tensioning regulator 13 places the flexible steel wire rope 4 in a relatively relaxed state. At this time, the spring 513 is in a natural state, and its elastic force causes the top rod 511 to move to the side away from the turntable 212. At this time, the top rod 511 does not contact the turntable 212, and the turntable 212 can rotate freely. The wind flow guide plate 5 can automatically rotate and adjust its direction under the action of wind. When it is necessary to fix the photovoltaic mounting frame 2, the third rotary driver 134 is started to drive the winding rod 131 to wind the flexible steel wire rope 4. As the flexible steel wire rope 4 is wound, its length shortens and its tension increases. Since the flexible steel wire rope 4 is located on the upper side of the connecting rope 515, when the tension of the flexible steel wire rope 4 increases, it will pull down the connecting rope 515, and the connecting rope 515 will then pull the connecting rod 514, thereby driving the external frame 512 to move in the direction close to the turntable 212. The movement of the external frame 512 overcomes the elastic force of the spring 513, causing the push rod 511 to move along the insertion hole 216 toward the turntable 212. When the push rod 511 abuts the outer wall of the turntable 212, the turntable 212 is restricted from rotating, thereby locking the angle of the airflow guide plate 5. During the movement of the push rod 511, the guide rod 516 on the external frame 512 is inserted into the guide sleeve 217 on the outer wall of the mounting base 21. The guide rod 516 and the guide sleeve 217 serve as a guide, ensuring that the push rod 511 can accurately move along the axis of the insertion hole 216, preventing the push rod 511 from deflecting or getting stuck during movement. The friction grooves provided on the side of the turntable 212 increase the friction between the push rod 511 and the outer wall of the turntable 212. When the push rod 511 abuts the outer wall of the turntable 212, the rotation of the turntable 212 can be more effectively restricted, improving the reliability of the angle locking. This embodiment utilizes the coordinated operation of the flexible steel cord 4, connecting cord 515, connecting rod 514, external frame 512, top rod 511, and spring 513 to automatically drive the angle locking unit 51 to lock the angle of the airflow guide plate 5 when the flexible steel cord 4 is tightened. This automatic locking function eliminates the need for additional control devices, simplifies the operation process, and improves the device's intelligence and ease of use.

[0057] Working Principle: During use, the fixing frame 11 of the first supporting part 1 is mounted on the ground using the surrounding fixing legs 111 to ensure stable fixation of the first supporting part 1. The main support frame 12 is vertically positioned at the center of the fixing frame 11, and the photovoltaic mounting frame 2 is mounted on top of the main support frame 12 using the universal adjustment unit 3. Several photovoltaic panels are installed on the upper surface of the photovoltaic mounting frame 2. The universal adjustment unit 3 then makes preliminary adjustments to the tilt angle and direction of the photovoltaic mounting frame 2 based on the initial installation requirements. As the position of the sun changes throughout the day, the universal adjustment unit 3 can be used to adjust the tilt angle and direction of the photovoltaic mounting frame 2 so that the photovoltaic panels face the sunlight as directly as possible, thereby improving the utilization of solar energy. When the tilt angle of the photovoltaic mounting frame 2 needs to be further stabilized, the tension of the flexible steel wire 4 is adjusted using the tensioning adjuster 13 to loosen the flexible steel wire 4. When the flexible steel wire 4 is tightened, it provides stable support for the tilt angle of the photovoltaic mounting frame 2. On the other hand, the flexible steel cable 4 is in transmission connection with the angle locking unit 51, which drives the angle locking unit 51 to lock the wind deflector 5. In a windy environment, if the flexible steel cable 4 is in a relaxed state, the wind deflector 5 can be affected by the wind and rotate within the mounting base 21. By rotating, the wind deflector 5 adjusts its angle to adapt to the wind direction, thereby reducing the impact of the wind on the photovoltaic mounting frame 2.
