Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation supporting technology, and more specifically, to a photovoltaic power generation ground pile. Background Art

[0002] Among photovoltaic power generation supporting facilities, helical ground piles are a new type of solar photovoltaic supporting product, which is suitable for various solar photovoltaic, wind power and construction industries, such as solar power station pile foundations, billboard pile foundations, sign flag pile foundations, wooden house pile foundations, etc. They are suitable for various geological conditions, such as clay, Gobi Desert, gravel, etc., and have high load performance, stability, anti-settlement and anti-pull-out properties.

[0003] Publication No. CN219825242U discloses a photovoltaic support ground pile. It includes a ground pile body, comprising a lower fixing part and an upper connecting part. The connecting part is characterized by a connecting pin and a lightning protection grounding component, while the fixing part is equipped with a fixing mechanism, which is a segmented grounding spiral or a steel reinforcement frame. By segmenting the grounding spiral, the function of uniformly distributed spiral blades is achieved while reducing material loss from the spiral blades. To ensure more stable fixation of the ground pile in sandy soil conditions, a steel reinforcement frame can be added to the fixing part and connected to the concrete foundation pile. However, in the prior art, if the soil is loose after the ground pile is rotated and inserted into the ground, the surrounding soil may become unstable during the rotation process, making the ground pile less secure and affecting the subsequent installation of the photovoltaic support. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a photovoltaic power generation ground pile that can improve the stability of the ground pile after it is inserted into the ground.

[0005] A photovoltaic power generation ground pile includes a ground pile body with a pointed tip at the lower end. A spiral plate is fixed to the outer wall of the ground pile body. The upper end of the ground pile body is recessed downward to form an installation space. A horizontal insertion mechanism is provided in the installation space. At least two elongated holes communicating with the installation space are opened on the side wall of the ground pile body. The horizontal insertion mechanism includes an insertion plate that slides on the bottom wall of the installation space. The insertion plate is provided with a cutting edge that slides in the elongated holes. The horizontal insertion mechanism also includes a rotating rod that is rotatably connected to the bottom wall of the installation space. The rotating rod is provided with a threaded part. An installation ring is threadedly connected to the rod body located at the threaded part. A push block adapted to the number and position of the insertion plate is fixed to the side wall of the installation ring. An inclined surface is opened on the insertion plate.

[0006] Furthermore, the number of insert plates is adapted to the number of elongated holes.

[0007] Furthermore, a first limiting groove is provided on the inner wall of the installation space, a positioning rod with its free end sliding in the first limiting groove is fixedly connected to the side wall of the installation ring, and a roller is rotatably connected to the push block.

[0008] Furthermore, the lowest point of the inclined plane is located on the side closer to the push block.

[0009] Furthermore, the rotating rod is coaxial with the ground pile body.

[0010] Furthermore, a second limiting groove is provided on the bottom wall of the installation space, and a limiting slider adapted to the second limiting groove is fixedly connected to the lower end of the insert plate. The limiting slider slides within the second limiting groove.

[0011] Furthermore, the insert plate has several grooves at equal intervals at the blade portion.

[0012] Furthermore, a positioning ring is fitted onto the rotating rod, and a connecting rod connects the positioning ring to the mounting space.

[0013] Furthermore, a hexagonal head is fixed to the upper end of the rotating rod.

[0014] Furthermore, a connecting plate is provided at the upper end of the ground pile body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, after the pile body is drilled into the ground, the rotating rod is rotated. Under the constraint of the first limiting groove and the positioning rod, the mounting ring can move downward. When the roller contacts the inclined surface, as the mounting ring continues to move downward, the roller pushes the insert plate through the elongated hole and inserts it into the stratum, so that the pile body and the stratum form a lateral contact, thereby improving the stability of the pile body.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment:

[0025] like Figure 1-4 As shown, a photovoltaic power generation ground pile includes a ground pile body 1, with a spiral blade 2 fixedly connected to the outer wall of the ground pile body 1. A pointed tip 3 is provided at the lower end of the ground pile body 1 for drilling into the ground. A connecting plate 4 is provided at the upper end of the ground pile body 1 for connecting to the output end of a pile driving machine (the connection method is a conventional technique and will not be described in detail here). The upper surface of the ground pile body 1 is recessed downwards to form an installation space 5. A horizontal insertion mechanism 6 is provided within the installation space 5. At least two elongated holes 7 are opened on the side wall of the ground pile body 1, and the elongated holes 7 are connected to the installation machine. Within the installation space 5, the horizontal insertion mechanism 6 includes an insertion plate 61 that slides on the bottom wall of the installation space 5. The insertion plate 61 is provided with a blade 611, which slides within an elongated hole 7. At least two insertion plates 61 are provided, and the number of insertion plates 61 matches the number of elongated holes 7. After the pile body 1 is drilled into the ground, the insertion plate 61 slides through the elongated hole 7 and is inserted into the stratum, so that the pile body 1 forms a lateral contact with the stratum and reduces the amplitude of the pile body 1's swaying due to geological loosening, thereby improving the stability of the pile after it is inserted into the ground.

[0026] like Figure 1-4As shown, the horizontal insertion mechanism 6 also includes a rotating rod 62 rotatably connected to the bottom wall of the installation space 5. The rotating rod 62 is coaxial with the ground pile body 1. The rotating rod 62 is provided with a threaded part 63. An installation ring 64 is threadedly connected to the rod body of the rotating rod 62 at the threaded part 63. A first limiting groove 51 is opened in the inner wall of the installation space 5. A positioning rod 65 with its free end sliding in the first limiting groove 51 is fixedly connected to the side wall of the installation ring 64. Through the cooperation of the first limiting groove 51 and the positioning rod 65, when the rotating rod 62 is rotated, the installation ring 64 can move along the length direction of the rotating rod 62. A push block 66 adapted to the number and position of the insertion plates 61 is fixedly connected to the side wall of the installation ring 64. An inclined surface 612 with the lowest point located near the push block 66 is opened on the insertion plate 61. A roller 67 is rotatably connected to the push block 66. After the pile body 1 is drilled into the ground, the rotating rod 62 is rotated. Under the constraint of the first limiting groove 51 and the positioning rod 65, the mounting ring 64 can move downward. When the roller 67 contacts the inclined surface 612, as the mounting ring 64 continues to move downward, the roller 67 pushes the insert plate 61 through the elongated hole 7 and inserts it into the stratum, so that the pile body 1 forms a lateral contact with the stratum, thereby improving the stability of the pile body 1.

[0027] like Figure 1-4 As shown, the bottom wall of the installation space 5 is provided with a second limiting groove 52 with an inverted T-shaped cross section. The lower end of the insert plate 61 is fixedly connected to a limiting slider 68 that is adapted to the second limiting groove 52. The limiting slider 68 slides in the second limiting groove 52 to improve the movement stability of the insert plate 61. After the installation ring 64 moves downward so that the roller 67 passes the lowest point of the inclined plane 612 and does not contact the inclined plane 612, the push block 66 abuts against the side wall of the insert plate 61 on the side closest to the insert plate 61, so that the insert plate 61 will not retract into the installation space 5 under the pressure of the stratum.

[0028] like Figure 1-4 As shown, the insert plate 61 is also provided with several grooves 613 at equal intervals at the blade 611. By setting the grooves 613 in the blade 611, the contact area between the insert plate 61 and the formation is increased, and the stability is further improved.

[0029] like Figure 1-4 As shown, a positioning ring 8 is fitted on the rotating rod 62. A connecting rod 9 is connected between the positioning ring 8 and the inner wall of the installation space 5. One end of the connecting rod 9 is fixedly connected to the positioning ring 8, and the other end is fixedly connected to the inner wall of the installation space 5. By setting the positioning ring 8, the stability of the rotating rod 62 during rotation can be improved and the probability of its shaking can be reduced.

[0030] like Figure 1-4 As shown, a hexagonal head 10 is fixedly connected to the upper end of the rotating rod 62. The operator can use a wrench to engage with the hexagonal head 10 to facilitate the rotation of the rotating rod 62.

[0031] like Figure 1-4 As shown, the spiral blades 2 are segmented on the pile body 1 to reduce the lateral resistance between the spiral cross section and the underground soil layer, thereby reducing the drilling difficulty.

[0032] The working principle of a photovoltaic power generation ground pile in this embodiment is as follows: In use, the connecting plate 4 is connected to the output end of the pile driver, and the pile driver drills the ground pile body 1 into the ground. After the ground pile body 1 is drilled into the ground, it is engaged with the hexagonal head 10 by a wrench. The rotating rod 62 is rotated by the wrench. Under the constraint of the first limiting slide groove 51 and the positioning rod 65, the mounting ring 64 can move downward. When the roller 67 contacts the inclined surface 612, as the mounting ring 64 continues to move downward, the roller 67 pushes the insert plate 61 through the elongated hole 7 and inserts it into the ground. After the mounting ring 64 moves downward and the roller 67 passes the lowest point of the inclined surface 612 and does not contact the inclined surface 612, the push block 66 abuts against the side wall of the insert plate 61 on the side close to the insert plate 61 and the vertical side wall of the insert plate 61. This prevents the insert plate 61 from retracting into the installation space 5 under the pressure of the ground, so that the ground pile body 1 forms a lateral contact with the ground, thereby improving the stability of the ground pile body 1.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
