Abstract
Description
Technical Field
[0001] This invention relates to a highly stable photovoltaic column, belonging to the field of photovoltaic support technology. Background Technology
[0002] With the continued growth of global demand for clean energy, solar photovoltaic power generation, as a clean and renewable energy source, has been widely used and vigorously developed. As a key supporting structure of photovoltaic power generation systems, the stability and adaptability of photovoltaic brackets directly affect the safe operation and power generation efficiency of the power generation system. The columns, as the basic components connecting the photovoltaic brackets to the ground, play a crucial role in this process.
[0003] Currently, conventional ground pile structures have many limitations in the application of photovoltaic power station construction. To improve the grip of ground piles on the soil, existing ground piles usually have several sets of ground spikes at their bottom. The ground spikes are inserted into the soil to enhance the anchoring effect. For example, patent publication number CN219041673U discloses a photovoltaic support with high stability. The ground piles are inserted deep into the soil. On this basis, the setting of the insertion rod and the inverted pile spikes adds another layer of fixed insurance measures to the ground pile spikes, further enhancing the stability of the photovoltaic support.
[0004] However, in the aforementioned patents, the insertion of the ground spikes relies on a screw drive to achieve downward insertion. But relying solely on the downward pressure transmitted by the screw to drive the ground spikes into the ground makes it difficult for the ground spikes to overcome soil resistance and reach the designed depth in hard soil, frozen soil, and strata containing many obstacles. This results in the ground spikes not reaching the required insertion depth, affecting the installation quality. Secondly, in the aforementioned patents, the multiple ground spikes are set at fixed intervals. In geology with hard soil or a lot of gravel, the ground piles are difficult to insert smoothly, increasing the construction difficulty and cost, and making it difficult to effectively adapt to complex and changing geological conditions. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention provides a highly stable photovoltaic pillar that uses a drive mechanism to rotate the ground spikes, making them easier to insert into the soil. Furthermore, the adjustable spacing of the ground spikes allows for flexible adjustment of the spike layout according to different geological conditions and engineering requirements.
[0006] The technical solution adopted by the present invention to solve its technical problem is: a highly stable photovoltaic column, comprising: a column, a fixing plate fixed to the top of the column, and a photovoltaic bracket fixed to the top of the fixing plate, a through hole opened inside the column, and several sets of notches opened on the outside of the through hole, a disc arranged in the through hole, and several sets of fixing rods fixed to the outside of the disc, a sliding sleeve sleeved on the fixing rod, and a spiral ground spike rotatably connected to the bottom of the sliding sleeve; An adjustment mechanism is also provided in the through hole, which is used to drive the disk to move vertically; Several sets of mounting plates are fixed on the upper outer side of the column, and a driven wheel is rotatably connected to the top of the mounting plate. A drive sleeve is provided below the driven wheel, and a drive rod is provided above the spiral ground spike, with the top of the drive rod located inside the drive sleeve. A drive mechanism is also provided above the column, which is used to drive the driven wheel to rotate.
[0007] Preferably, the column is fixed with a cone.
[0008] Preferably, the fixing rod passes through the sliding sleeve and is slidably connected to it, and a locking bolt is provided at one end of the sliding sleeve.
[0009] Preferably, the bottom of the driven wheel is connected to the drive sleeve via a universal coupling, and the spiral ground spike is connected to the drive rod via a universal coupling.
[0010] Preferably, the inner wall of the drive sleeve and the cross-section of the drive rod are both polygonal.
[0011] Preferably, the adjusting mechanism includes a lead screw, which is vertically disposed in a through hole, and guide rods are fixed at both ends inside the through hole. The lead screw and guide rods both pass through the disc, and the lead screw and the disc are connected by a thread. A motor is fixed at the top of the column, and the output end of the motor is connected to the lead screw.
[0012] Preferably, the driving mechanism includes a gear ring, which is sleeved on the column above by a bearing and meshes with several sets of driven wheels. A second motor is fixed at the bottom of the fixed plate, and a drive wheel is provided at the output end of the second motor, which meshes with the gear ring.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The drive mechanism drives multiple driven wheels to rotate, and the power is transmitted to the drive sleeve through universal coupling one. Then, through the polygonal drive rod and universal coupling two, the spiral spike is driven to rotate. At the same time, the adjustment mechanism drives the disc and the fixed rod to move down, so that the rotating spiral spike gradually cuts into the soil. Compared with the static insertion of the comparative case, the rotational cutting insertion can directly break up the clumps and small obstacles in hard soil and frozen soil, significantly reducing the insertion resistance and ensuring that the spike accurately reaches the design depth. This solves the problem of difficulty in insertion and insufficient depth in hard soil layers in the comparative case, which relies on the downward pressure of the screw. The spiral spikes are slidably connected to the fixed rod via a sliding sleeve. The spacing between adjacent spikes can be easily adjusted with the help of locking bolts. When there are obstacles such as gravel, bricks, or hard soil blocks at the bottom of the pit, the locking bolts of the corresponding sliding sleeves of a single spiral spike can be loosened, and its radial position can be adjusted along the fixed rod to avoid the obstacles before tightening the locking bolts to fix it. Compared with the fixed-spacing spikes in the comparison case, which cause the whole spikes to jam when one is blocked during insertion, independent adjustment can ensure that other spikes can be inserted normally, avoiding the interruption of the overall construction due to local obstacles, and greatly improving the construction pass rate under complex geological conditions. The driven wheel and drive sleeve, and the spiral spike and drive rod are connected by universal couplings, which can adapt to the angle changes of the spiral spike during the adjustment of the spacing, ensuring that the spiral spike can transmit power to it in all positions. This adjustability allows the column to flexibly adapt to different geological conditions and load requirements, improving construction efficiency and installation quality under complex geological conditions.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-4 The present invention provides a technical solution: A highly stable photovoltaic column includes: a column 1, a fixing plate 2 fixed to the top of the column 1, and a photovoltaic bracket 3 fixed to the top of the fixing plate 2. The column 1 has a through hole inside, and several sets of notches are opened on the outside of the through hole. A disc 5 is provided in the through hole, and several sets of fixing rods 6 are fixed on the outside of the disc 5. A sliding sleeve 7 is sleeved on the fixing rod 6, and a spiral ground spike 8 is rotatably connected to the bottom of the sliding sleeve 7. An adjustment mechanism 10 is also provided in the through hole, which is used to drive the disc 5 to move vertically; Several sets of mounting plates 11 are fixed on the upper outer side of the column 1, and a driven wheel 12 is rotatably connected to the top of the mounting plate 11. A drive sleeve 14 is provided below the driven wheel 12, and a drive rod 15 is provided above the spiral ground spike 8, with the top of the drive rod 15 located inside the drive sleeve 14. A drive mechanism 17 is also provided above the column 1, which is used to drive the driven wheel 12 to rotate.
[0019] Furthermore, the column 1 serves as the main support structure, with the photovoltaic bracket 3 supported at the top by the fixing plate 2. The disc 5 in the through hole inside the column 1 is connected to the sliding sleeve 7 by the fixing rod 6. The spiral ground spike 8 at the bottom of the sliding sleeve 7 extends out of the notch on the outside of the column 1. During operation, the adjusting mechanism 10 drives the disc 5 to move vertically, causing the spiral ground spike 8 to rise and fall. At the same time, the driving mechanism 17 drives the driven wheel 12 on the mounting plate 11 to rotate. The power is transmitted to the spiral ground spike 8 through the driving sleeve 14 and the driving rod 15, causing it to rotate and insert into the soil. The anchoring stability of the column 1 is enhanced by the combination of rotation cutting and vertical feeding.
[0020] In this implementation: the column 1 is fixed with a cone 4.
[0021] Furthermore, the cone 4 fixed at the bottom of the column 1 plays a guiding role in the initial stage of column 1 installation, and the tip of the cone structure reduces the resistance when inserting into the foundation pit.
[0022] In this embodiment: the fixing rod 6 passes through the sliding sleeve 7 and is slidably connected to it, and a locking bolt 9 is provided at one end of the sliding sleeve 7.
[0023] Furthermore, the fixing rod 6 passes through the sliding sleeve 7 and forms a sliding fit. When the locking bolt 9 is loosened, the sliding sleeve 7 can slide along the fixing rod 6 to adjust the spacing of the spiral spikes 8. After the adjustment is completed, the locking bolt 9 is tightened to fix the position of the sliding sleeve 7, so as to realize the flexible adjustment of the spacing of the spikes and adapt to different soil conditions.
[0024] In this embodiment: the bottom of the driven wheel 12 is connected to the drive sleeve 14 via a universal coupling 13, and the spiral spike 8 is connected to the drive rod 15 via a universal coupling 16.
[0025] Furthermore, the driven wheel 12 is connected to the drive sleeve 14 via universal coupling 13, and the spiral spike 8 is connected to the drive rod 15 via universal coupling 2 16. When the pitch of the spiral spike 8 is adjusted, causing the angle to change, universal coupling 13 and universal coupling 2 16 can adaptively deflect to ensure that the rotational power is stably transmitted from the driven wheel 12 to the spiral spike 8.
[0026] In this embodiment: the inner wall of the drive sleeve 14 and the cross-section of the drive rod 15 are both polygonal.
[0027] Furthermore, the inner wall of the drive sleeve 14 and the cross-section of the drive rod 15 are both polygonal. The two transmit torque through the interlocking of their edges. When the spacing of the spiral spikes 8 is adjusted, causing the angle between the drive sleeve 14 and the drive rod 15 to change, the drive rod 15 can adaptively move inside the drive sleeve 14 to ensure power transmission.
[0028] In this embodiment: the adjusting mechanism 10 includes a lead screw 1001, which is vertically arranged in a through hole, and guide rods 1002 are fixed at both ends inside the through hole. The lead screw 1001 and the guide rods 1002 both pass through the disc 5, and the lead screw 1001 and the disc 5 are connected by a thread. A motor 1003 is fixed at the top of the column 1, and the output end of the motor 1003 is connected to the lead screw 1001.
[0029] Furthermore, the motor 1003 drives the lead screw 1001 to rotate. Since the lead screw 1001 is threadedly connected to the disc 5 and the guide rod 1002 restricts the rotation of the disc 5, the disc 5 moves vertically as the lead screw 1001 rotates, thereby driving the spiral spikes 8 to rise and fall synchronously.
[0030] In this embodiment: the drive mechanism 17 includes a gear ring 1701, which is sleeved on the column 1 via a bearing and meshes with several sets of driven wheels 12. A second motor 1702 is fixed at the bottom of the fixed plate 2, and a drive wheel 1703 is provided at the output end of the second motor 1702, which meshes with the gear ring 1701.
[0031] Furthermore, motor 1702 drives drive wheel 1703 to rotate, drive wheel 1703 meshes with gear ring 1701 to make it rotate, gear ring 1701 simultaneously meshes with multiple sets of driven wheels 12 to achieve synchronous rotation of multiple sets of spiral ground spikes 8, ensuring balanced force during insertion and improving construction efficiency.
[0032] The workflow of this embodiment is as follows: Align the cone 4 at the bottom of the column 1 with the foundation pit, insert the column 1 into the foundation pit to the preset depth to complete the foundation positioning, and then adjust the position of the spiral ground spike 8 individually according to the soil conditions at the bottom of the foundation pit, such as whether there are obstacles such as gravel or hard soil clods. Loosen the locking bolt 9 on the corresponding sliding sleeve 7 to allow the sliding sleeve 7 to slide along the fixed rod 6, thereby changing the radial position of the spiral ground spike 8. When there is an angular deviation in the adjustment of the position of the spiral ground spike 8, the universal coupling 13 and the universal coupling 16 can adaptively deflect. After adjusting the spiral spike 8 to a position that avoids obstacles or is suitable for soil hardness, tighten the locking bolt 9 to fix the position of the sliding sleeve 7 and the spiral spike 8, ensuring that each spike is in the optimal working position. Then start the motor 1702, whose output end drives the drive wheel 1703 to rotate. The drive wheel 1703 meshes with the gear ring 1701, causing the gear ring 1701 to rotate around the column 1. The gear ring 1701 meshes with multiple sets of driven wheels 12 on the mounting plate 11, transmitting rotational power to the driven wheels 12, so that all driven wheels 12 rotate synchronously. The rotation of wheel 12 is transmitted to drive sleeve 14 via universal coupling 13. Drive sleeve 14 rotates synchronously with driven wheel 12. Since the inner wall of drive sleeve 14 and the cross-section of drive rod 15 are both polygonal, drive sleeve 14 drives drive rod 15 to rotate. The rotation of drive rod 15 is transmitted to spiral ground spike 8 via universal coupling 16, causing spiral ground spike 8 to generate a rotational cutting action. Then, motor 1003 is started, and its output end drives lead screw 1001 to rotate in the through hole of column 1. Since lead screw 1001 is threadedly connected to disc 5, disc 5... The disc 5 moves vertically downward along the guide rod 1002. The disc 5 drives the sliding sleeve 7 and the spiral spike 8 to move down synchronously through the fixing rod 6, so that the spiral spike 8 is inserted into the soil at the bottom of the foundation pit. The spiral spike 8 rotates and breaks up the soil particles, overcomes the resistance of hard soil and frozen soil, and gradually penetrates into the soil until the preheating depth. After the spiral spike 8 is inserted into the soil, it forms a spiral interlocking structure with the soil. Multiple spikes work together from different positions. Combined with the initial fixation of the cone 4, the pull-out resistance and overturning resistance of the column 1 are significantly improved, and the stable installation of the photovoltaic column is completed.
