[0002] In a photovoltaic power generation system, the photovoltaic support frame is a key component that supports the photovoltaic panels. By adjusting the angle of the photovoltaic support frame, the photovoltaic panels can be made as perpendicular to the sunlight as possible, thereby improving the photovoltaic panels' absorption efficiency of solar energy and increasing power generation. In severe weather, damage can be reduced by adjusting the angle.

[0003] Based on the above, the photovoltaic brackets currently in use mainly achieve transmission through a rotatable transmission method, which has a limited rotation angle, making it inconvenient to adjust the position according to weather and sunlight, and is not conducive to movement and adjustment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an angle adjustment drive device for photovoltaic brackets, which solves the problem mentioned in the background art that the existing photovoltaic brackets mainly achieve transmission through a rotatable transmission method, which has a limited rotation angle, is inconvenient to adjust the position according to the weather and sunlight, and is not conducive to movement and adjustment.

[0005] The purpose and function of the angle adjustment drive device for photovoltaic brackets of this utility model are achieved by the following specific technical means:

[0006] An angle adjustment drive device for a photovoltaic support includes a base frame, on which two sets of side supports are fixedly installed on the top two sides. A vertical sliding groove structure is formed in the middle of the adjacent surfaces of the two sets of side supports. A photovoltaic panel has downwardly extending transmission frames fixedly installed on both sides of its edges. A tube shaft is rotatably mounted in the middle of each transmission frame in conjunction with a bearing. A lifting frame is fixedly installed outside each tube shaft, and the lifting frames slide vertically within the sliding grooves of one set of side supports. A worm gear A is rotatably mounted inside the transmission frame, and a worm wheel A is fixedly mounted outside the tube shaft. The worm gear A and worm wheel A are connected in a transmission manner.

[0007] Furthermore, side racks are fixedly installed on both sides of the interior of the side support frame.

[0008] Furthermore, a receiving frame is fixedly installed on the top of the base frame, and the photovoltaic panel can be fitted and accommodated in the receiving frame.

[0009] Furthermore, two sets of worm gears B are rotatably installed on the upper outer side of the lifting frame; a buckle is fixedly installed on the outside of the lifting frame, and two sets of worm wheels B and lifting gears are rotatably installed between the lifting frame and the buckle; the worm wheels B and the lifting gears are coaxially connected, the worm wheels B are drivenly connected to the worm gears B, and the lifting gears mesh with the side rack.

[0010] Furthermore, a drive base is fixedly installed at the bottom of the photovoltaic panel, and drive shafts A and B are rotatably installed on both sides of the drive base. Two sets of motors are installed outside the drive base to provide power to drive shafts A and B respectively.

[0011] Furthermore, the drive shaft A and the worm gear A are connected by a bevel gear transmission.

[0012] Furthermore, the drive shaft B passes through the tube shaft and is connected to the two sets of worm gears B by bevel gear transmission.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the motor is directly controlled by a program to achieve precise adjustment of the angle and height of the photovoltaic panel. The angle adjustment allows the photovoltaic panel to be aligned with the sun in real time, and can be adjusted according to environmental needs to make full use of sunlight resources and significantly improve photovoltaic power generation efficiency. In addition, the height of the photovoltaic panel can be adjusted, and photovoltaic panels in different positions can be moved to different heights as needed for operation.

[0016] This utility model adopts a modular and vulnerable design to reduce maintenance costs. The side support is treated as an independent vulnerable component.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides an angle adjustment drive device for photovoltaic brackets, including a base frame 1, two sets of side supports 101 are fixedly installed on the top two sides of the base frame 1, and a vertical sliding groove structure is opened in the middle of the adjacent surfaces of the two sets of side supports 101; a photovoltaic panel 3, a downwardly extending transmission frame 301 is fixedly installed on both sides of the photovoltaic panel 3, a tube shaft 303 is rotatably installed in the middle of the transmission frame 301 in cooperation with the bearing, and a lifting frame 5 is fixedly installed on the outside of the tube shaft 303. The lifting frame 5 slides vertically in the sliding groove of a set of side supports 101; a worm gear A302 is rotatably installed inside the transmission frame 301, and a worm wheel A304 is fixedly installed on the outside of the tube shaft 303. The worm gear A302 and the worm wheel A304 are connected in a transmission connection.

[0028] Side racks 102 are fixedly installed on both sides of the interior of the side support frame 101.

[0029] The base frame 1 is fixedly equipped with a receiving frame 2, and the photovoltaic panel 3 can be fitted and accommodated in the receiving frame 2.

[0030] Two sets of worm gears B501 are rotatably installed on the upper outer side of the lifting frame 5; a buckle 502 is fixedly installed on the outside of the lifting frame 5; two sets of worm wheels B503 and lifting gears 504 are rotatably installed between the lifting frame 5 and the buckle 502; the worm wheels B503 and lifting gears 504 are coaxially connected, the worm wheels B503 are connected to the worm gears B501 for transmission, and the lifting gears 504 mesh with the side rack 102.

[0031] Among them, a drive base 4 is fixedly installed at the bottom of the photovoltaic panel 3, and drive shafts A401 and B402 are rotatably installed on both sides of the drive base 4. Two sets of motors are installed outside the drive base 4 to provide power to drive shafts A401 and B402 respectively.

[0032] The drive shaft A401 and the worm gear A302 are connected by a bevel gear transmission.

[0033] The drive shaft B402 passes through the tube shaft 303 and is connected to the two sets of worm gears B501 by bevel gear transmission.

[0034] Photovoltaic panel height adjustment principle: After setting the height parameters through the program, the motor starts and drives the drive shaft B402 to rotate.

[0035] Bevel gear steering transmission: Drive shaft B402 changes the power direction through bevel gear set, transmitting rotational power to worm gear B501.

[0036] Worm gear meshing transmission: When the worm B501 rotates, it drives the worm wheel B503 to rotate synchronously, and the two achieve power transmission through meshing.

[0037] Gear and rack linkage: The rotation of the worm gear B503 drives the coaxial lifting gear 504 to rotate. The teeth of the lifting gear 504 engage with the side rack 102, generating a vertical force through the meshing relationship of the gear and rack.

[0038] Height adjustment: The side rack 102 is fixedly connected to the photovoltaic panel 3. When the gear rotates, it pushes the rack to move up and down, thereby driving the photovoltaic panel 3 to achieve height adjustment.

[0039] Gear and rack transmission characteristics: Utilizing the principle of converting gear rotation into linear motion, the photovoltaic panel height can be smoothly raised and lowered by precisely controlling the gear speed and direction, and the transmission process has high precision and load capacity.

[0040] Closed-loop control: The motor speed and number of rotations are monitored in real time by the program, combined with sensor feedback (such as a height encoder) to ensure that the photovoltaic panel 3 stays at the target height and avoids overshoot or position deviation. Example 2

[0041] Severe weather protection mechanisms;

[0042] Angle Repositioning: Upon detecting severe weather signals (such as hail or sandstorm), the program controls photovoltaic panel 3 to rotate 180 degrees, switching it from normal power generation to... Figure 2 The plane is facing downwards, which reduces the windward area and the risk of panel exposure.

[0043] Height Reduction: After the angle of photovoltaic panel 3 is adjusted, drive shaft B402 starts, and through gear and rack transmission, photovoltaic panel 3 is slowly lowered until it falls into the receiving frame 2 (e.g., Figure 3 state).

[0044] Containment and protection: The structural design of the containment frame 2 can wrap the photovoltaic panel 3 to form a physical protective barrier to prevent the panel surface from being directly impacted or eroded by wind and sand; at this time, only the side support frame 101 is exposed, which has a simple structure, low cost, and is easy to replace and maintain later.

[0045] Active risk avoidance logic: Through a combination of "angle flipping + height reduction + package containment", the delicate photovoltaic panel 3 components are incorporated into the protective structure to minimize the probability of damage from severe weather.

[0046] Cost optimization strategy: The side frame 101 is designed independently as a vulnerable component, sacrificing some structural costs in exchange for the safety of the core power generation components, which is in line with the economic principle of engineering protection.

[0047] Mechatronics control: The program-preset parameters are combined with mechanical transmission to achieve automatic adjustment of angle and height, reducing manual intervention.

[0048] Self-locking characteristics of the transmission chain: The self-locking function of the worm gear transmission (such as fixing the worm wheel when adjusting the angle) ensures that the photovoltaic panel 3 remains stable in the non-adjusted state and avoids shaking due to external forces such as wind.

[0049] Modular protection design: The housing frame 2 is separated from the transmission mechanism, which can quickly perform the storage action when protecting, and does not affect the power generation efficiency of the photovoltaic panel 3 when working normally.

[0050] The specific usage and function of this embodiment are as follows:

[0051] In this utility model, the base frame 1 is fixed to the ground, and multiple sets are arranged in an array;

[0052] When the angle needs to be adjusted, the motor can be directly controlled to rotate the drive shaft A401 through a program. The drive shaft A401, in conjunction with the bevel gear, drives the worm gear A302 to rotate. The worm gear A302 and the worm wheel A304 generate a transmission effect. Since the worm wheel A304 is fixed, a reaction force is generated, causing the photovoltaic panel 3 to rotate itself, thus achieving angle adjustment. The maximum rotation angle is controlled by the program to not exceed 180 degrees.

[0053] When the height of the photovoltaic panel 3 needs to be adjusted, the motor is controlled by the program to drive the drive shaft B402 to rotate. The drive shaft B402, in conjunction with the bevel gear, drives the worm gear B501 to rotate. During the rotation of the worm gear B501, the worm wheel B503 is driven to rotate, and the lifting gear 504 rotates synchronously. During the rotation of the lifting gear 504, it engages with the side rack 102 to generate force to achieve up and down lifting, thereby adjusting the height of the photovoltaic panel 3.

[0054] In case of severe weather, you can choose to rotate the photovoltaic panel 3 180 degrees and adjust it to... Figure 2The photovoltaic panel 3 is then lowered into the receiving frame 2 via a rack and pinion drive. Figure 3 In this state, the containment frame 2 completely protects the photovoltaic panel 3, preventing damage to the photovoltaic panel 3 from severe weather such as hail or sandstorms; only the side support 101 may be affected by severe weather, and the side support 101 has a simple structure, low cost, and is easy to replace.
