DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] The present utility model provides as Figures 1 to 3A screw ground pile with adjustable installation height of the column is shown, including a column body 1. A spiral blade 2 is fixedly connected to the outside of the column body 1, and the spiral blade 2 is located in the lower half of the column body 1. By setting the spiral blade 2, when the column body 1 is driven into the ground, the spiral-shaped spiral blade 2 can be better anchored in the soil, providing greater uplift resistance.
[0021] A threaded groove 3 is opened on the upper surface of the column body 1. A round groove 4 is opened at the bottom of the threaded groove 3. The diameter of the round groove 4 is larger than that of the threaded groove 3. A threaded rod 5 is threadedly connected inside the threaded groove 3. A flange 14 is fixedly connected to the top of the threaded rod 5. A sliding plate 6 is slidably connected inside the round groove 4, and the sliding plate 6 is rotatably connected to the bottom end of the threaded rod 5.
[0022] Before use, the threaded rod 5 is retracted inside the threaded groove 3, which is convenient for handling and transferring.
[0023] By rotating the threaded rod 5 through the flange 14, the threaded rod 5 can be extended from the threaded groove 3, which is convenient for use; at the same time, the overall height of the screw ground pile can be adjusted, improving the flexibility of the screw ground pile in use; and the friction coefficient between the threaded rod 5 and the threaded groove 3 is large, and it will not rotate randomly. At the same time, installation holes are opened on the flange 14, which is convenient for docking and installing with the photovoltaic bracket.
[0024] To improve the stability of the screw ground pile, a ring box 7 is fixedly connected to the outside of the column body 1. A second gas passage 12 is opened inside the column body 1. One end of the second gas passage 12 penetrates through the inner wall of the round groove 4, and the other end of the second gas passage 12 penetrates through the inner wall of the ring box 7. The ring box 7 is communicated with the round groove 4 through the second gas passage 12. A square tube 8 is fixedly connected to the outer ring of the ring box 7. A plurality of square tubes 8 are provided, and the plurality of square tubes 8 are evenly distributed around the outer ring of the ring box 7. A first gas passage 11 is opened inside the wall body of the square tube 8. One end of the first gas passage 11 penetrates through the inner wall of the ring box 7, and the other end of the first gas passage 11 penetrates through the inner wall of the square tube 8. The square tube 8 is communicated with the ring box 7 through the first gas passage 11. A sliding rod 9 is slidably arranged inside the square tube 8, and the sliding rod 9 penetrates through the end of the square tube 8 far away from the ring box 7.
[0025] To facilitate the gas in the round groove 4 to enter the inside of the ring box 7, the ring box 7 is located at the connection of the threaded groove 3 and the round groove 4.
[0026] After the column 1 is driven into the ground, the threaded rod 5 is rotated through the flange 14. The threaded rod 5 extends out of the thread groove 3, increasing the overall height of the screw pile for easy use and allowing the height to be adjusted according to specific usage conditions. During the upward movement of the threaded rod 5, the sliding plate 6 is driven to move upward inside the circular groove 4, and the gas in the circular groove 4 is pressed into the inside of the square cylinder 8 through the second gas passage 12, the ring box 7, and the first gas passage 11, causing the sliding rod 9 to extend outward and embed into the soil, improving the stability of the screw pile during use. When the flange 14 is rotated in the reverse direction, the sliding rod 9 can be retracted, facilitating handling and transfer.
[0027] By providing structures such as the threaded rod 5 and the square cylinder 8, the threaded rod 5 is retracted inside the thread groove 3, facilitating handling and transfer. During use, the column 1 is driven into the ground, and the threaded rod 5 is rotated through the flange 14. The threaded rod 5 extends out of the thread groove 3, increasing the overall height of the screw pile for easy use and allowing the height to be adjusted according to specific usage conditions. At the same time, the sliding rod 9 extends outward and embeds into the soil, improving the stability of the screw pile during use.
[0028] To improve the efficiency of the sliding rod 9 embedding into the soil, a pointed block 10 is fixedly connected to the end of the sliding rod 9 located outside the square cylinder 8.
[0029] A reinforcing plate 13 is fixedly connected to the bottom of the square cylinder 8, and the reinforcing plate 13 is embedded in the ground to prevent the screw pile from rotating randomly when the flange 14 is rotated.
