Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a spiral ground pile photovoltaic support. Background Art

[0002] With the development of solar power generation in my country, high-quality land resources with good sunshine, flat terrain, and favorable construction conditions are becoming increasingly scarce. Land with less favorable conditions, such as mountainous areas, has gradually become the primary land resource for construction. When constructing a solar photovoltaic power generation system in mountainous areas, it is necessary to set up photovoltaic racks in the construction area and install solar panels on them.

[0003] Traditional photovoltaic racking installation typically requires drilling equipment to drive multiple piles into the construction area at intervals. The tops of these piles together form the mounting area for the solar panels. However, the piles have a small outer diameter. When localized forces are applied to the piles, the exposed portion of the piles can easily bend, leading to unstable solar panel installation. Utility Model Content

[0004] In view of the above problems, the utility model provides a spiral ground pile photovoltaic support.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is as follows:

The support comprises two spiral piles arranged at intervals, one end of the spiral pile being provided with a drill bit for driving into the ground, the other end of the spiral pile being provided with a flange for cooperating with and being mounted on a drilling device, spiral leaves being provided on the outer wall of the end of the spiral pile close to the drill bit, and a truss being connected between the two spiral piles via a connecting piece.

[0007] Furthermore, the truss includes two mutually parallel mounting rods and multiple web members, the two mounting rods are arranged between two spiral piles from top to bottom, the multiple web members are arranged between the two mounting rods along the length direction of the mounting rods, and two adjacent web members are combined into a V shape on a plane parallel to the two mounting rods, and both ends of the mounting rods are connected to the corresponding spiral piles through connecting parts.

[0008] Furthermore, the connecting piece is a long cylindrical hoop, which is sleeved on the outer wall of the spiral pile away from the spiral blade, and the two ends of the mounting rod are respectively connected to the long cylindrical hoop of the two spiral piles.

[0009] Furthermore, the long cylindrical clamp includes two clamps symmetrically arranged on the outer wall of the spiral pile, and the clamps are provided with an arc surface for fitting with the outer wall of the spiral pile. The two clamps are provided with clamping parts for driving themselves to clamp on the outer wall of the spiral pile, and the two ends of the mounting rod are respectively connected to the clamps of the two spiral piles.

[0010] Furthermore, the portion of the splint that contacts the outer wall of the screw pile is coated with inorganic zinc-rich paint.

[0011] Furthermore, the clamping member includes multiple sets of limiting bolts and limiting nuts, and the clamping plates extend from the outer wall of the spiral pile on both sides parallel to the axis of the spiral pile. The clamping plates are provided with multiple through holes for the limiting bolts to pass through at the positions extending from the outer wall of the spiral pile. After passing through the through holes on the two clamping plates, the multiple limiting bolts are threadedly connected with the corresponding limiting nuts.

[0012] Furthermore, the connecting parts are two short cylindrical hoops, which are spaced apart and sleeved on the outer wall of the spiral pile at one end away from the spiral blade. The same ends of the two mounting rods are respectively connected to the two short cylindrical hoops of the same spiral pile.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] The present application discloses a spiral ground pile photovoltaic support, referring to Figure 1 and Figure 2 The invention comprises two spaced-apart screw piles 1. A drill bit 11 for driving into the ground is integrally fixed to one end of each pile. A flange 12 for mounting on ground-drilling equipment is welded to the other end. Spiral blades 13 are welded to the outer wall of the end of the pile 1 closest to the drill bit 11. A truss 2 is connected between the two piles 1 via a connector.

[0023] In the embodiment of the present application, depending on the length of the truss 2, construction workers can use ground drilling equipment to rotate and drive the two spiral piles 1 into the ground in sequence, and then install the truss 2 through the connectors on the part of the two spiral piles 1 that is exposed above the ground. After the photovoltaic bracket array is installed in the construction area, the solar electrode panel can be installed on the top of the spiral piles 1. A spiral ground pile photovoltaic bracket of the present application can connect the two spiral piles 1 into a whole through the truss 2, thereby enhancing the bending resistance of the part of the spiral piles 1 that is exposed above the ground and improving the stability of the solar panel installation.

[0024] Specifically, the truss 2 includes two parallel mounting rods 21 and multiple web members 22. The two mounting rods 21 are spaced apart from each other from top to bottom between two screw piles 1. The multiple web members 22 are spaced apart along the length of the mounting rods 21, and adjacent web members 22 are combined to form a V-shape on a plane parallel to the mounting rods 21. Both ends of the mounting rods 21 are connected to the corresponding screw piles 1 via connectors.

[0025] In the embodiment of the present application, the mounting rod 21 and the web 22 can distribute the bending moment on the exposed portion of the screw pile 1, further improving the bending resistance of the exposed portion of the screw pile 1. The web 22 can be mounted on the mounting rod 21 by screws.

[0026] Specifically, the connecting piece is a long cylindrical hoop 3 , which is sleeved on the outer wall of the spiral pile 1 away from the spiral blade 13 , and both ends of the mounting rod 21 are respectively connected to the long cylindrical hoop 3 of the two spiral piles 1 .

[0027] In the embodiment of the present application, after driving two screw piles 1, the construction workers can install the long cylindrical clamp 3 on the part of the screw pile 1 exposed to the ground, and then install the two ends of the mounting frame on the corresponding long cylindrical clamp 3. The long cylindrical clamp 3 can withstand external forces together with the screw pile 1, further improving the bending resistance of the screw pile 1.

[0028] Specifically, the long cylindrical clamp 3 includes two clamping plates 31 symmetrically arranged on the outer wall of the screw pile 1. Each clamping plate 31 has an arc-shaped surface for contacting the outer wall of the screw pile 1. The two clamping plates 31 are mounted with clamping members 4 for clamping themselves to the outer wall of the screw pile 1. The two ends of the mounting rod 21 are respectively connected to the clamping plates 31 of the two screw piles 1.

[0029] In the embodiment of the present application, two clamps 31 can be installed on the part of the screw pile 1 exposed to the ground through the clamping member 4, and then the bolts are passed through the mounting rod 21 and the clamps 31, and the nuts are tightened to install the mounting rod 21 on the clamps 31.

[0030] In order to increase the friction between the splint 31 and the outer wall of the screw pile 1 , the portion of the splint 31 that is in contact with the outer wall of the screw pile 1 is coated with an inorganic zinc-rich paint.

[0031] Specifically, the clamping member 4 includes multiple sets of limiting bolts 41 and limiting nuts 42. The clamping plates 31 extend from the outer wall of the screw pile 1 on both sides parallel to the axis of the screw pile 1. The clamping plates 31 are provided with multiple through holes for the limiting bolts 41 to pass through at the locations where they extend from the outer wall of the screw pile 1. The limiting bolts 41 pass through the through holes of the two clamping plates 31 and then threadably engage with the corresponding limiting nuts 42. By tightening the multiple sets of limiting bolts 41 and limiting nuts 42, the clamping plates 31 can be securely mounted on the screw pile 1.

[0032] The implementation principle of Example 1 is as follows: Depending on the length of the truss 2, construction workers can use ground drilling equipment to rotate and drive two spiral piles 1 into the ground in sequence, and then install the truss 2 using connectors on the part of the two spiral piles 1 that is exposed above the ground. After the photovoltaic bracket array is installed in the construction area, the solar electrode panel can be installed on the top of the spiral piles 1. The spiral ground pile photovoltaic bracket of the present application can connect the two spiral piles 1 into a single body through the truss 2, thereby enhancing the bending resistance of the part of the spiral piles 1 that is exposed above the ground and improving the stability of the solar panel installation.

[0033] Example 2

[0034] Reference Figure 3 The difference between Example 2 and Example 1 is that the connecting members are two short cylindrical clamps 5, which are spaced apart and sleeved on the outer wall of the end of the screw pile 1 away from the spiral blade 13. The same end of the two mounting rods 21 is respectively connected to the two short cylindrical clamps 5 of the same screw pile 1. The distance between the two mounting rods 21 can be adjusted by adjusting the spacing between the two short cylindrical clamps 5.

[0035] In this embodiment of the present application, after the construction workers drive two screw piles 1 into the ground, they can install two short cylindrical clamps 5 at intervals on the exposed portion of the screw piles 1. By increasing the spacing between the two short cylindrical clamps 5, the distance between the two mounting rods 21 can be increased. After the distance between the two mounting rods 21 is adjusted, multiple web members 22 can be nailed to the two mounting rods 21, thereby increasing the size of the truss 2 and further improving the bending resistance of the screw piles 1.
