Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic power generation facility construction technology, and in particular to a rapid construction module for photovoltaic foundations suitable for complex terrain. Background Technology
[0002] With the increasing global demand for renewable energy, photovoltaic power generation, as an important component of clean energy, is expanding in scale and its application scenarios are gradually extending to areas with complex terrain and harsh environments.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: cast-in-place concrete foundations require on-site excavation, formwork, steel reinforcement binding, pouring and curing, resulting in a long construction cycle, high dependence on the transportation of water and building materials, and large-scale excavation will seriously damage the original vegetation and soil structure, causing soil erosion. Although prestressed pipe piles can reduce earthwork excavation, they require the entry of large piling equipment, which is difficult to operate on steep, soft or rocky foundations, and is costly and poses safety hazards. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of traditional photovoltaic foundation construction in areas with complex terrain, such as terrain and geological limitations, difficulty in accessing mechanical equipment, and great damage to the ecological environment. To this end, we propose a rapid construction module for photovoltaic foundations suitable for complex terrain.
[0005] To achieve the above objectives, this application adopts the following technical solution: a rapid construction module for photovoltaic foundations suitable for complex terrain, comprising a spiral steel pile, a first flange fixed to the top of the spiral steel pile, a second flange disposed on the top of the first flange, the first flange and the second flange being of the same size, a plurality of bolts installed on the top of the second flange, the bolts being evenly distributed circumferentially around the axis of the second flange, and the bottom end of the bolts being threaded through the first flange and connected to a nut.
[0006] Preferably, a universal joint is fixed to the top of the second flange.
[0007] Preferably, a first expansion base is provided on one side of the spiral steel pile, and a second expansion base is provided on the other side of the spiral steel pile. The facing surfaces of the first expansion base and the second expansion base are both provided with arc-shaped grooves. The diameter of the arc-shaped grooves is larger than the diameter of the spiral steel pile. The first expansion base and the second expansion base are both located at the bottom of the first flange.
[0008] Preferably, three insertion posts are fixed on both sides of the second extension chassis near the end of the first extension chassis, and three insertion holes that are slidably connected to the insertion posts are opened on both sides of the first extension chassis near the end of the second extension chassis.
[0009] Preferably, both the bottom of the first and second extended chassis are fixed with a fixing cone.
[0010] Preferably, a counterweight is installed on the top of the first extended chassis, and a through hole is opened in the middle of the counterweight, the diameter of which is larger than the diameter of the second flange.
[0011] Preferably, hooks are fixed on both sides of the top of the counterweight.
[0012] The technical effects and advantages of this utility model are as follows: In this utility model, the main support force is provided by spiral steel piles, which are anchored underground. This can avoid large-scale earthwork excavation, protect the fragile ecology, adapt to varied geology, and adapt to various geological conditions such as slope, rock, and soft soil. It solves the problems of cast-in-place concrete foundations requiring on-site excavation, formwork, steel bar binding, pouring and curing, resulting in long construction cycles and high dependence on the transportation of water and building materials. In this invention, when the spiral steel pile is halfway anchored underground, the first and second expansion base plates are connected, allowing the insertion post to be inserted into the insertion hole, thus connecting the insertion post and the second expansion base plate. When the spiral steel pile is fully anchored underground, the fixing cones at the bottom of the first and second expansion base plates are inserted into the ground. By setting up the first and second expansion base plates, a larger base plate is added to the bottom of the first flange to distribute the pressure and prevent sinking. Attached Figure Description

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.
[0016] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a photovoltaic foundation rapid construction module suitable for complex terrain, including a spiral steel pile 1, a first flange 2 fixed to the top of the spiral steel pile 1, a second flange 3 set on the top of the first flange 2, the first flange 2 and the second flange 3 having the same size, a plurality of bolts 4 installed on the top of the second flange 3, the bolts 4 being evenly distributed circumferentially around the axis of the second flange 3, the bottom end of the bolts 4 penetrating the first flange 2 and threadedly connected to a nut 5, and a universal joint 6 fixed to the top of the second flange 3; Specifically: The operator first connects to the first flange 2 using specialized equipment, then uses the equipment to rotate and drive the spiral steel pile 1 into the ground. After that, the connection between the equipment and the first flange 2 is disconnected, and the second flange 3 is installed on top of the first flange 2, thereby fixing the position of the universal joint 6. The universal joint 6 can be used to finely adjust the angle and level, perfectly fit the uneven ground, and ensure the flatness of the upper support. The spiral steel pile 1 provides the main support force and anchors underground, avoiding large-scale earthwork excavation, protecting the fragile ecology, and adapting to various geological conditions such as slope, rock, and soft soil. It solves the problems of long construction cycles and high dependence on water and building material transportation for cast-in-place concrete foundations, which require on-site excavation, formwork, steel bar binding, pouring, and curing.
[0017] Reference Figure 3 and Figure 4 As shown in this embodiment: a first expansion base plate 7 is provided on one side of the spiral steel pile 1, and a second expansion base plate 8 is provided on the other side of the spiral steel pile 1. Arc-shaped grooves 12 are opened on the facing surfaces of the first expansion base plate 7 and the second expansion base plate 8. The diameter of the arc-shaped grooves 12 is larger than the diameter of the spiral steel pile 1. The first expansion base plate 7 and the second expansion base plate 8 are both located at the bottom of the first flange 2. Three inserts 9 are fixed on both sides of the second expansion base plate 8 near the end of the first expansion base plate 7. Three insertion holes 10 that are slidably connected to the inserts 9 are opened on both sides of the first expansion base plate 7 near the end of the second expansion base plate 8. A fixing cone 11 is fixed at the bottom of the first expansion base plate 7 and the second expansion base plate 8. Specifically: When the spiral steel pile 1 is halfway anchored underground, the first expansion base plate 7 and the second expansion base plate 8 are connected, so that the insert post 9 is inserted into the interior of the insertion hole 10, connecting the insert post 9 and the second expansion base plate 8. When the spiral steel pile 1 is completely anchored underground, the fixing cone 11 at the bottom of the first expansion base plate 7 and the second expansion base plate 8 is inserted into the ground. Through the setting of the first expansion base plate 7 and the second expansion base plate 8, a larger base plate is added to the bottom of the first flange 2 to distribute the pressure and prevent sinking. The fixing cone 11 can ensure the fixed position of the first expansion base plate 7 and the second expansion base plate 8 and prevent displacement. The insert post 9 and the insertion hole 10 prevent the first expansion base plate 7 and the second expansion base plate 8 from being on the same horizontal plane.
[0018] Reference Figure 1 As shown in this embodiment: a counterweight 13 is installed on the top of the first extended chassis 7, and a through hole 15 is opened in the middle of the counterweight 13. The diameter of the through hole 15 is larger than the diameter of the second flange 3. Hooks 14 are fixed on both sides of the top of the counterweight 13. Specifically: After the spiral steel pile 1 is fully anchored, the counterweight 13 is installed on the top of the first extension chassis 7 and the second extension chassis 8 through the hook 14 to resist the upward pulling force.
[0019] Working principle: The operator first connects to the first flange 2 using specialized equipment, then uses the equipment to rotate and drive the spiral steel pile 1 into the ground. Afterwards, the connection between the equipment and the first flange 2 is released, and the second flange 3 is installed on top of the first flange 2, thus fixing the position of the universal joint 6. The universal joint 6 allows for fine-tuning of angle and level, perfectly conforming to uneven ground and ensuring the upper support is level. When the spiral steel pile 1 is halfway anchored underground, the first extension base plate 7 and the second extension base plate 8 are connected, allowing the insertion post 9 to be inserted into the insertion hole 10, connecting the insertion post 9 and the second extension base plate 8. When fully anchored underground, the fixing cones 11 at the bottom of the first extension base plate 7 and the second extension base plate 8 are inserted into the ground. The installation of the first extension base plate 7 and the second extension base plate 8 adds a larger base plate to the bottom of the first flange plate 2 to distribute the pressure and prevent sinking. The fixing cones 11 can ensure the fixed position of the first extension base plate 7 and the second extension base plate 8 and prevent displacement. The insertion post 9 and the insertion hole 10 prevent the first extension base plate 7 and the second extension base plate 8 from being on the same horizontal plane. After the spiral steel pile 1 is fully anchored, the counterweight block 13 is installed on the top of the first extension base plate 7 and the second extension base plate 8 through the hook 14 to resist the upward pull force.
[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
