Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a photovoltaic support anchor according to an embodiment of the present invention includes: The anchor pile body 1 is slender and hollow, and its interior forms a receiving cavity 2 with an assembly port 10 at the top. The assembly port 10 is configured to receive and accommodate the bottom connection end of the photovoltaic bracket. Multiple openings 20 are provided on the lower part of the side wall of the anchor pile body 1. Multiple movable wing 21 are rotatably mounted on the lower part of the inner wall of the receiving cavity 2 via a pivot 22. The movable wing 21 has a first position that is housed within the receiving cavity 2 and a second position that extends out of the anchor pile body 1 through the opening 20. When the multiple movable wing 21 are in the second position, they extend outward from the anchor pile body 1 to enhance the anti-slip and anti-pull-out properties of the anchor pile body 1 in the soil. An operating mechanism is located within the accommodating cavity 2 and is drivenly connected to each movable side wing 21. The operating mechanism is configured to cause the multiple movable side wings 21 to move synchronously from a first position to a second position. A fastening assembly is provided at the top of the anchor pile body 1 to fix the bottom connection end of the photovoltaic bracket inserted into the assembly port 10.

[0017] In use, by setting up deployable movable side wings 21 and operating mechanism, the pull-out resistance of the ground anchor after installation can be adjusted, which significantly improves the stability and pull-out resistance of the ground anchor in the soil; the design of the accommodating cavity 2 and the assembly port 10 makes the installation of the photovoltaic bracket more convenient and reliable; the pivot 22 is fixedly set in the accommodating cavity 2 by welding, and the movable side wings 21 are rotatably connected to the pivot 22.

[0018] The operating mechanism includes: a threaded rod 3, which is arranged along the axial direction of the accommodating cavity 2; a disc 30, which is fixedly connected to the bottom end of the threaded rod 3; a rotating part 31, which is connected to the top end of the threaded rod 3; a first reinforcing rod 32 and a second reinforcing rod 33, which are laterally fixed to the inner sidewall of the accommodating cavity 2 and are spaced apart vertically; wherein, the first reinforcing rod 32 is provided with a threaded hole 34 that is threadedly engaged with the threaded rod 3, and the second reinforcing rod 33 is provided with a guide hole 35 through which the threaded rod 3 passes.

[0019] During use, the mating design of the threaded rod 3 and the reinforcing rod provides a stable mechanical transmission method, ensuring the reliability and durability of the operating mechanism. The threaded hole 34 of the first reinforcing rod 32 and the guide hole 35 of the second reinforcing rod 33 work together to ensure the stability and accuracy of the threaded rod 3 during movement. The first reinforcing rod 32 and the second reinforcing rod 33 are fixedly connected to the anchor pile body 1 by welding or other fixing methods, and the outer surfaces of the first reinforcing rod 32 and the second reinforcing rod 33 are adapted to the outer arc surface of the anchor pile body 1. The upper part of the threaded rod 3 has external threads in the section that mates with the threaded hole 34, while the rest is a smooth section, which improves the ease of assembly of the threaded rod 3.

[0020] The disc 30 is positioned below the plurality of movable side wings 21; the bottom end of the threaded rod 3 is fixedly connected to the center of the disc 30.

[0021] In use, the disc 30 is positioned below the movable side wing 21 and fixedly connected to the threaded rod 3. This structural design allows the movable side wing 21 to be deployed synchronously by rotation, making operation simple and mechanical transmission efficient.

[0022] There are three movable side wings 21, which are rotatably mounted on the inner wall of the accommodating cavity 2 via a pivot 22.

[0023] When in use, the symmetrical arrangement of the three movable side wings 21 ensures that the ground anchor is subjected to uniform force in the soil, provides all-round pull-out resistance, and effectively prevents the ground anchor from rotating or shifting in the soil.

[0024] The movable side wing 21 has a vertical parallelogram structure, and a contact slope 23 is formed on the side of the movable side wing 21 that is close to the disk 30. When the movable side wing 21 is in the second position, the contact slope 23 of the movable side wing 21 abuts against the upper surface of the disk 30.

[0025] When in use, the design of the movable side wings 21 of the parallelogram structure and its contact slope 23 ensures that they form a large area of ​​contact with the disk 30 in the unfolded state, resulting in high force transmission efficiency and strong structural stability.

[0026] The fastening assembly includes multiple fastening nuts 11 fixed to the outer periphery of the top of the anchor pile body 1, and multiple fastening holes 12 opened on the side wall of the anchor pile body 1 and coaxially aligned with each fastening nut 11; the fastening holes 12 communicate with the inner holes of the fastening nuts 11 to the receiving cavity 2.

[0027] In use, the mating design of the fastening nut 11 and the fastening hole 12 provides multi-point and multi-directional fastening capability, ensuring the firmness and reliability of the connection between the photovoltaic bracket and the ground anchor; wherein the fastening nut 11 is fixedly connected to the anchor pile body 1 by welding or other fixing methods. The top side wall of the anchor pile body 1 is also provided with at least one pair of coaxially arranged through holes 24, which are located below the fastening nut 11 and pass through the receiving cavity 2.

[0028] In use, the through hole 24 provides an additional connection point, and the connection strength between the photovoltaic bracket and the ground anchor is further enhanced by bolt connection, forming a double protection mechanism.

[0029] The specific working process of this utility model is as follows: First, the anchor pile body 1 is driven or buried into the foundation at a predetermined depth. At this time, the movable side wing 21 is in the storage position (first position) and is completely contained in the accommodating cavity 2. The bottom connecting end of the photovoltaic bracket is inserted into the assembly port 10 of the anchor pile body 1. The rotating part 31 of the tool rotation operating mechanism drives the threaded rod 3 to rotate. During the rotation, the threaded rod 3 generates an upward axial displacement by engaging with the threaded hole 34 of the first reinforcing rod 32 and being guided in the guide hole 35 of the second reinforcing rod 33. The threaded rod 3 drives the disc 30 to move upward, and the disc 30 pushes the movable side wing 21, causing it to rotate around the pivot 22. The movable side wing 21 gradually unfolds, passes through the opening 20 on the anchor pile body 1, and extends into the surrounding soil, reaching a fully unfolded state (second position). During the unfolding process of the movable side wing 21, its parallelogram structure design ensures that the contact slope 23 forms a complete surface contact with the upper surface of the disc 30. Secure the photovoltaic bracket by fastening components: First, pass the external fastener (bolt) through the fastening hole 12 and screw it into the fastening nut 11 to initially tighten the photovoltaic bracket; then, insert the locking bolt through the through hole 24, pass it through the corresponding hole on the photovoltaic bracket, and tighten it with the locking nut to form a through-limiting connection; check whether each connection is secure to complete the installation.
