Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic ground piles, and more specifically, to a composite photovoltaic ground pile with a spiral anti-pull-out structure. Background Technology
[0002] Photovoltaic ground piles are used to fix photovoltaic support frames. In terrains such as loose soft soil, sandy land, and swamps, ground piles are usually used with photovoltaic support frames during installation. Driving the ground piles into the ground provides stable and reliable foundation support for the photovoltaic support frame, improving the stability of the photovoltaic support frame and photovoltaic panels. However, in related photovoltaic support frame ground pile technology, the overall structure of the ground pile is relatively simple, consisting of a simple ground insert with a helical blade. In actual use, the helical blade can only prevent the ground pile from being pulled out. The simple pull-out resistance structure results in limited pull-out resistance of the ground pile, making it easy to pull out. It is not suitable for use in terrains such as loose soft soil, sandy land, and swamps. Utility Model Content
[0003] To overcome the above shortcomings, this application provides a composite photovoltaic ground pile with a spiral anti-pull-out structure, which aims to improve the problem that the ground pile has limited pull-out resistance due to the single pull-out structure, making it easy to pull out and unsuitable for use in loose soft soil, sandy land and swampy terrain.
[0004] This application provides a composite photovoltaic ground stake with a spiral anti-pull-out structure, including a ground insert and a limiting component.
[0005] The ground insert is externally fixed with a spiral blade, and a first through groove is opened on both sides of the spiral blade. The spiral blade is set in an inverted cone shape.
[0006] The limiting assembly includes connecting rods, connecting blocks, double-ended bolts, and limiting plates. Two connecting rods are provided, both rotatably connected to the floor plug. The two connecting rods are slidably inserted into the interior of both sides of the floor plug. Each connecting rod corresponds to one of the two first through slots. The top of each connecting rod is rotatably connected to a connecting block. The two ends of the double-ended bolt are threaded through the bodies of the two connecting blocks. Two limiting plates are provided, both arc-shaped, and fixedly connected to the bottom ends of the two connecting rods. Both limiting plates are slidably inserted into the interior of the floor plug.
[0007] In one specific implementation, the top of the ground plug is provided with a connecting plate, and the bottom of the ground plug is set in a conical shape.
[0008] In one specific implementation, the connecting plate has a plurality of connecting holes, which are evenly distributed in a circular pattern.
[0009] In one specific implementation, the top of the ground plug is provided with a second through groove, the top ends of the two connecting rods are rotatably inserted into the interior of the second through groove, the rods of the two connecting rods are fixedly penetrated by a rotating shaft, and the two ends of the two rotating shafts are respectively rotatably connected to the groove walls on both sides of the second through groove.
[0010] In one specific implementation, slots are provided on both sides of the ground plug, the two slots are symmetrically arranged, the top of the two slots are connected to the second through slot, and the rods of the two connecting rods are respectively rotatably inserted into the interior of the two slots.
[0011] In one specific implementation, both connecting blocks are located inside the second through groove, and the double-ended bolt is rotatably inserted into the second through groove, with one end of the double-ended bolt having a hexagonal head.
[0012] In one specific implementation, one side of one of the connecting blocks is provided with a limiting rod, and the block body of the other connecting block is slidably sleeved on the rod body of the limiting rod.
[0013] In one specific implementation, a limiting groove is provided at the bottom of both slots, and both limiting grooves are set in an arc shape. The two limiting plates are respectively rotatably inserted into the two slots.
[0014] The beneficial effects of this utility model are as follows: The composite photovoltaic ground stake with a spiral anti-pull-out structure obtained by the above design can be used by rotating the ground stake and the spiral blades. The spiral blades can drive the ground stake into the ground. Then, the double-headed bolt can be rotated, which drives the two connecting blocks to move relative to each other, thereby driving the top ends of the two connecting rods to move relative to each other. The two connecting rods will rotate, thereby causing the bottom ends of the two connecting rods and the two limiting plates to move in opposite directions. This allows the limiting plates to detach from the ground stake and enter the soil. The spiral blades and the two limiting plates can prevent the ground stake from being pulled out. Furthermore, the spiral blades are designed with an inverted conical shape, which can improve the pull-out resistance of the ground stake, making it difficult for the ground stake to be pulled out. Therefore, it is suitable for use in loose soft soil, sandy land, and swampy terrain. Attached Figure Description

[0025] Please see Figure 1-3The top of the ground plug 100 is provided with a connecting plate 110, and the bottom of the ground plug 100 is set in a conical shape. The plate body of the connecting plate 110 has a number of connecting holes 111, which are evenly distributed in a circle to fix the photovoltaic support frame on the connecting plate 110. The ground plug 100 is fixedly fitted with a spiral blade 120. The spiral blade 120 has a first through groove 121 on both sides and is set in an inverted conical shape.
[0026] Please see Figure 1-5 The limiting component 200 includes a connecting rod 210, a connecting block 220, a double-headed bolt 230, and a limiting plate 240. There are two connecting rods 210, and both connecting rods 210 are rotatably connected to the ground plug 100. The top of the ground plug 100 is provided with a second through groove 101. The top ends of the two connecting rods 210 are rotatably inserted into the interior of the second through groove 101. The rod body of the two connecting rods 210 is fixedly penetrated by a rotating shaft 211. The two ends of the two rotating shafts 211 are rotatably connected to the groove walls on both sides of the second through groove 101, respectively.
[0027] In the specific setup, two connecting rods 210 are slidably inserted into the interior of the two sides of the floor plug 100. Slots 102 are provided on both sides of the floor plug 100. The two slots 102 are symmetrically arranged. The two slots 102 are respectively connected to the two first through slots 121. The top of the two slots 102 are connected to the second through slot 101. The rods of the two connecting rods 210 are rotatably inserted into the interior of the two slots 102. The two connecting rods 210 are respectively corresponding to the two first through slots 121. The connecting rods 210 can rotatably pass through the interior of the first through slots 121.
[0028] In this application, the top ends of the two connecting rods 210 are rotatably connected to connecting blocks 220. The two ends of the double-ended bolts 230 are threaded through the blocks of the two connecting blocks 220 respectively. The two connecting blocks 220 are located inside the second through groove 101. The double-ended bolts 230 are rotatably inserted into the second through groove 101. One end of the double-ended bolts 230 is provided with a hexagonal head 231. One side of one connecting block 220 is provided with a limit rod 221. The block of the other connecting block 220 is slidably sleeved on the rod of the limit rod 221.
[0029] In this embodiment, two limiting plates 240 are provided. Both limiting plates 240 are arc-shaped.

[0030] Specifically, the working principle of this composite photovoltaic ground pile with a spiral anti-pull-out structure is as follows: During use, the ground insert 100 and the spiral blade 120 can be rotated. The spiral blade 120 drives the ground insert 100 into the ground. Then, the hexagonal head 231 and the double-ended bolt 230 can be rotated. The double-ended bolt 230 drives the two connecting blocks 220 to move relative to each other, which in turn drives the top ends of the two connecting rods 210 to move relative to each other. This allows the bottom ends of the two connecting rods 210 and the two limiting plates 240 to... Reverse movement allows the limiting plate 240 to disengage from the limiting groove 103, allowing it to enter the soil. The photovoltaic support frame can then be fixed to the connecting plate 110. The spiral blade 120 and the two limiting plates 240 prevent the ground plug 100 from being pulled out. The spiral blade 120 is designed with an inverted conical shape, which improves the pull-out resistance of the ground plug 100, making it less likely to be pulled out. This makes it suitable for use in loose soft soil, sandy land, and swampy terrain.
