Description

Construction Device and Method for Photovoltaic Support Foundation Based on Adaptive Adjustment Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and specifically to a photovoltaic support foundation construction device and method based on adaptive adjustment. Background Technology

[0002] With the continuous growth of global demand for clean energy, photovoltaic (PV) power generation, as an important renewable energy source, has been widely applied and developed rapidly. In the construction of PV power plants, the construction quality of the PV support foundation is crucial, directly affecting the stability of the PV support and the power generation efficiency of the PV modules. However, in complex terrain conditions, such as uneven terrain, mountainous areas with significant slope differences, and spoil heaps with highly random and uneven soil textures, traditional PV support foundation construction devices and methods face numerous challenges. Most often, pre-embedded cement pillars are used in conjunction with the PV support installation. By rationally designing the foundation dimensions and depth, various loads borne by the PV support can be effectively resisted, including self-weight, wind load, and snow load. This not only allows for better adaptation to different terrain changes based on ground elevation variations, ensuring that the PV modules maintain a suitable installation angle to maximize solar radiation reception, but also guarantees the stability of the PV support under complex terrain conditions.

[0003] To address this, this application designs a photovoltaic support foundation construction device and method based on adaptive adjustment. Existing photovoltaic supports, when installed with pre-embedded cement pillars, usually require manual installation and alignment. Due to the generally large size of photovoltaic supports, it is difficult to calibrate the coaxiality between the photovoltaic support and the pre-embedded cement pillars, resulting in high labor costs and cumbersome, time-consuming, and labor-intensive installation procedures. After the photovoltaic support is installed, some support connectors need to be removed when replacing the photovoltaic panels. Since existing photovoltaic supports mostly use bolt fixing, secondary disassembly and reassembly can lead to bolt stripping and photovoltaic support deformation, increasing replacement costs. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a photovoltaic support foundation construction device and method based on adaptive adjustment. This effectively solves the problems in existing technologies, such as the difficulty in calibrating the coaxiality between the photovoltaic support and the pre-embedded cement pillar due to the generally large size of photovoltaic supports, high labor costs, and cumbersome, time-consuming, and labor-intensive installation procedures; the need to dismantle some support connectors when replacing photovoltaic panels, and the fact that secondary disassembly and reassembly of existing photovoltaic supports, which often use bolt fixing, can lead to bolt stripping, photovoltaic support deformation, and increased replacement costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a photovoltaic support foundation construction device and method based on adaptive adjustment, comprising:

[0007] Several pre-embedded support bodies are provided. A positioning plate is fixedly sleeved on the lower side of the outer wall of the pre-embedded support body. A docking column is installed on the upper end of the pre-embedded support body. A sliding sleeve is movably sleeved in the middle of the outer wall of the pre-embedded support body. A support plate is provided on the upper end of the docking column. A photovoltaic panel body is provided above several support plates. An angle adjustment part is provided on each adjacent sliding sleeve and support plate. An installation alignment part is provided on each adjacent docking column and support plate.

[0008] The angle adjustment part includes guide rods symmetrically installed on the outer wall of the sliding sleeve. The upper ends of the guide rods on both the front and rear sides slide through the support plate. Columns are symmetrically installed on the upper part of the support plate. A purlin support plate is provided on the upper side between the columns on the left and right sides. An adjustment group is provided on both the guide rods on the front and rear sides and the purlin support plate.

[0009] The installation alignment part includes a torsion sleeve installed at the lower end of the sliding sleeve. The lower end of the torsion sleeve is provided with a clamp, which consists of clamp plates on both sides, a hinge shaft and fastening components. The upper end of the hinge shaft of the clamp is installed through the torsion sleeve.

[0010] Furthermore, the adjustment assembly includes a front diagonal brace and a diagonal brace sleeve hinged at the front and rear ends of the purlin support plate, respectively. The end of the diagonal brace sleeve away from the purlin support plate is provided with a receiving groove. A rear diagonal brace is slidably installed on the inner wall of the receiving groove by a tension spring. The ends of the front diagonal brace and the rear diagonal brace away from the purlin support plate are respectively hinged to the side wall on the lower side of the corresponding guide rod.

[0011] Furthermore, the adjustment group also includes a connecting sleeve plate installed at the lower end of several guide rods. The connecting sleeve plate is simultaneously movably fitted onto several pre-embedded support bodies through several clearance holes. Electric push rods are installed on the upper ends of the leftmost and rightmost positioning plates, and the telescopic ends of the electric push rods are fixedly connected to the connecting sleeve plate.

[0012] Furthermore, the installation alignment part also includes multiple sets of slots on the outer wall of the docking column. Each set of slots consists of several slots evenly distributed from top to bottom. The inner wall of the torsion sleeve is provided with installation grooves corresponding to several slots. A card plate is slidably installed on the inner wall of the installation groove by means of a compression spring.

[0013] Furthermore, the upper ends of several purlin support plates are fixedly connected to the corresponding photovoltaic panel bodies, and purlins are slidably installed through the upper ends of several purlin support plates. Strong magnets are embedded in the ends of the purlins away from the photovoltaic panel bodies corresponding to several purlin support plates.

[0014] Furthermore, a support shaft is slidably installed on several columns and several purlin plates. Both ends of the support shaft are detachably fitted with limit rings, and a limit plate is detachably installed on the upper end of the guide rod.

[0015] Furthermore, the inner wall of the sliding sleeve is fitted with a number of balls evenly distributed in a circle, and the inner walls of the several clearance holes on the connecting sleeve plate are also fitted with a number of balls evenly distributed in a circle.

[0016] In addition, a photovoltaic support foundation construction method based on adaptive adjustment, using a photovoltaic support foundation construction device based on adaptive adjustment, includes the following steps:

[0017] S1: During the sliding sleeve installation stage, the connecting sleeve plate is first movably fitted onto the outer wall of several pre-embedded support pillars, and then the pre-prepared photovoltaic bracket is movably fitted onto the outer wall of the corresponding pre-embedded support pillar.

[0018] S2: During the installation of the torsion sleeve, the torsion sleeve is movably fitted onto the outer wall of the docking column, so that several clamping plates are inserted into the corresponding clamping slots, and the clamps are controlled to lock and tightly fit onto the outer wall of the corresponding pre-embedded support body for fastening installation.

[0019] S3: During the photovoltaic panel installation stage, the support shaft is installed in sequence, and the two purlins are initially positioned and connected. Several photovoltaic panels are then placed on several purlin support plates and purlins in sequence, and several photovoltaic panels are then securely installed on the purlin support plates in sequence.

[0020] S4: During the photovoltaic panel tilt angle adjustment stage, the connecting sleeve is controlled to move up or down, which drives several photovoltaic supports to move up or down synchronously until several purlins drive the corresponding photovoltaic panels to rotate synchronously at the corresponding angle for adjustment.

[0021] S5: During the maintenance and replacement phase, remove several photovoltaic panel bodies, support shafts, and two purlins in sequence. Then, release the locking effect of the torsion sleeve and the docking column, and control the clamp to release the locking and loosen the outer wall of the corresponding pre-embedded support body. Then, several photovoltaic brackets can be removed in sequence for replacement.

[0022] The technical solution provided by this invention has the following advantages compared with the prior art:

[0023] This invention provides a photovoltaic support foundation construction device and method based on adaptive adjustment. When the torsion sleeve is movably fitted onto the outer wall of the docking column, several clamping plates will retract into their corresponding installation grooves for clearance. After the lower end of the sleeve is tightly fitted to the upper end of the docking column, the construction personnel rotate the torsion sleeve. At this time, the torsion sleeve will simultaneously drive several clamping plates to rotate synchronously, and the clamping plates will be inserted into their corresponding slots, thereby achieving a quick snap-fit ​​effect between the torsion sleeve and the docking column. Afterwards, the construction personnel control the clamp to lock and tightly fit it onto the outer wall of the corresponding pre-embedded support body for secure installation, further enhancing the connection stability between the photovoltaic support and the pre-embedded support body. The installation method of quick snap-fit ​​between the torsion sleeve and the docking column, and further locking the connection with the clamp, can quickly and conveniently carry out the installation work while ensuring the coaxiality of the photovoltaic support and the pre-embedded support body. This avoids the problems of difficult coaxiality calibration between the conventional photovoltaic support and the pre-embedded support body, high labor costs, and cumbersome, time-consuming, and labor-intensive installation steps.

[0024] During maintenance and replacement, if the photovoltaic bracket and photovoltaic panel body need to be disassembled and replaced after long-term use, the construction personnel first remove several photovoltaic panel bodies, support shafts, and two purlins in sequence. Then, the construction personnel rotate the torsion sleeve in the opposite direction. At this time, the torsion sleeve will simultaneously drive several clamping plates to rotate in the opposite direction. The clamping plates will exit from their corresponding slots and retract into their corresponding installation slides, thereby achieving the effect of quickly releasing the clamping effect between the torsion sleeve and the connecting column. Then, the construction personnel control the clamp to release the lock and loosen the outer wall of the corresponding pre-embedded support body. Several photovoltaic brackets composed of sliding sleeves, support plates, angle adjustment parts, and installation alignment parts can be removed one by one for replacement. This can achieve quick and convenient disassembly of photovoltaic panel bodies and photovoltaic brackets, and can avoid the problems of bolt stripping, photovoltaic bracket deformation, and increased replacement costs caused by secondary disassembly and reassembly due to the conventional bolt fixing method.

[0037] The present invention will be further described below with reference to embodiments.

[0038] Example:

[0039] Please refer to Figures 2-9. This invention provides a technical solution: a photovoltaic support foundation construction device and method based on adaptive adjustment, comprising:

[0040] Several pre-embedded support bodies 1 are evenly distributed from left to right and have different lengths. A positioning plate 2 is fixedly sleeved on the lower side of the outer wall of the pre-embedded support body 1. A docking column 3 is installed on the upper end of the pre-embedded support body 1, and a sliding sleeve 4 is movably sleeved in the middle of the outer wall of the pre-embedded support body 1. A support plate 5 is provided on the upper end of the docking column 3. The support plate 5 is composed of an annular plate and two extension plates at the front and rear. A photovoltaic panel body 6 is provided above several support plates 5. An angle adjustment part 7 is provided on each adjacent sliding sleeve 4 and support plate 5. An installation alignment part 8 is provided on each adjacent docking column 3 and support plate 5.

[0041] The angle adjustment part 7 includes guide rods 71 ​​symmetrically installed on the outer wall of the sliding sleeve 4. The guide rods 71 ​​and the sliding sleeve 4 are integrated into a single structure. The upper ends of the guide rods 71 ​​on both the front and rear sides slide through the support plate 5. The upper end of the support plate 5 is symmetrically installed with columns 72 on the left and right sides. A purlin support plate 73 is provided on the upper side between the columns 72 on the left and right sides. An adjustment group 74 is provided on the guide rods 71 ​​and the purlin support plate 73 on both the front and rear sides.

[0042] The mounting alignment part 8 includes a torsion sleeve 81 installed at the lower end of the sliding sleeve 4. A clamp 82 is provided at the lower end of the torsion sleeve 81. The clamp 82 consists of clamp plates on both sides, a hinge shaft and a fastening assembly. The upper end of the hinge shaft of the clamp 82 is installed through the torsion sleeve 81.

[0043] The adjustment assembly 74 includes a front diagonal brace 741 and a diagonal brace sleeve 742, which are respectively hinged to the front and rear ends of the purlin support plate 73. The diagonal brace sleeve 742 has a receiving groove at the end away from the purlin support plate 73. A rear diagonal brace 743 is slidably installed on the inner wall of the receiving groove by a tension spring. The ends of the front diagonal brace 741 and the rear diagonal brace 743 away from the purlin support plate 73 are respectively hinged to the side wall on the lower side of the corresponding guide rod 71.

[0044] The adjustment group 74 also includes a connecting sleeve plate 744 installed at the lower end of several guide rods 71. The connecting sleeve plate 744 is simultaneously movably fitted onto several pre-embedded support bodies 1 through several clearance holes. Electric push rods 745 are installed on the upper ends of the leftmost and rightmost positioning discs 2. The telescopic ends of the electric push rods 745 are fixedly connected to the connecting sleeve plate 744.

[0045] The mounting alignment part 8 also includes multiple sets of slots on the outer wall of the docking column 3. The multiple sets of slots are evenly distributed in a circle. Each set of slots consists of several slots evenly distributed from top to bottom. The inner wall of the torsion sleeve 81 is provided with mounting grooves corresponding to several slots. The mounting plate 83 is slidably mounted on the inner wall of the mounting groove by a compression spring. The slots, mounting grooves and mounting plate 83 are all arc-shaped structures, and the inner wall of the slots and the outer wall of the mounting plate 83 are all rounded.

[0046] Several purlin support plates 73 are fixedly connected to the corresponding photovoltaic panel body 6 at their upper ends. A purlin strip 731 is slidably installed through the upper ends of several purlin support plates 73. A strong magnet 732 is embedded in each of the several purlin support plates 73 at the end of the purlin strip 731 away from the photovoltaic panel body 6.

[0047] A support shaft 9 is slidably installed on several columns 72 and several purlin support plates 73. Both ends of the support shaft 9 can be detachably fitted with limit rings, and the upper end of the guide rod 71 can be detachably installed with a limit plate.

[0048] The inner wall of the sliding sleeve 4 is fitted with several balls 10 that are evenly distributed in a circle, and the inner walls of several clearance holes on the connecting sleeve plate 744 are also fitted with several balls 10 that are evenly distributed in a circle.

[0049] In practice:

[0050] Firstly, this application employs an angle adjustment unit 7 and an installation alignment unit 8 in conjunction with each other to install the photovoltaic bracket. The angle adjustment unit 7 is used to adjust the angle of the photovoltaic panel body 6 for sunlight tracking, while the installation alignment unit 8 assists in the installation of the angle adjustment unit 7 and can also adjust the installation height of the angle adjustment unit 7 to adapt to different ground elevations, thereby achieving the effect of freely adjusting the installation height of the photovoltaic panel body 6. It should be noted that before constructing the foundation of the photovoltaic bracket, based on the ground elevation, the foundation dimensions and burial depth should be reasonably designed, and several pre-embedded support pillar bodies 1 of different lengths should be evenly distributed from left to right and pre-embedded. They should be positioned on the ground using a positioning plate 2. The positioning plate 2 can play a positioning role during the pre-embedding process, ensuring the accuracy of the burial depth and position of the pre-embedded support pillar body 1, while increasing the contact area between the pre-embedded support pillar body 1 and the soil, thereby improving the stability of the photovoltaic bracket after installation.

[0051] During the installation of the sliding sleeve 4, it should be noted that the upper ends of the leftmost and rightmost positioning plates 2 are initially pre-installed with electric push rods 745, and several photovoltaic brackets consisting of sliding sleeves 4, support plates 5, angle adjustment parts 7, and installation alignment parts 8 need to be prepared in advance. The front and rear guide rods 71 ​​slide through the corresponding extension plates of the support plates 5, and the upper ends of the front and rear guide rods 71 ​​are equipped with detachable limiting plates. First, the construction personnel simultaneously and movably mount the connecting sleeves 744 onto the outer walls of several pre-embedded pillar bodies 1, and then fix the telescopic ends of the left and right electric push rods 745 onto the connecting sleeves 744 in sequence. Then, the construction personnel sequentially and movably mount the pre-prepared photovoltaic brackets onto the corresponding pre-embedded pillar bodies 1. During this process, several ball bearings 10 can reduce the friction between the sliding sleeves 4 and connecting sleeves 744 and the pre-embedded pillar bodies 1, so that they can slide up and down smoothly along the outer walls of the pre-embedded pillar bodies 1 for installation.

[0052] Specifically, during the process of the pre-prepared photovoltaic bracket being movably fitted onto the outer wall of the corresponding pre-embedded support body 1, the sliding sleeve 4 will be movably fitted onto the outer wall of the pre-embedded support body 1 via the ball bearings 10, while the torsion sleeve 81 will be movably fitted onto the outer wall of the connecting column 3. Assuming that the embedment depth of several pre-embedded support bodies 1 is consistent, until the lower end of the sliding sleeve 4 is tightly fitted against the upper end of the connecting column 3, it should be noted that before this, to ensure that the torsion sleeve 81 can be smoothly fitted onto the outer wall of the connecting column 3, the construction personnel need to control the orientation of the torsion sleeve 81, so that several clamping plates 83 on the inner wall of the torsion sleeve 81 are misaligned with several clamping grooves on the outer wall of the connecting column 3. When the torsion sleeve 81 is movably fitted onto the outer wall of the connecting column 3, several clamping plates 83 will be squeezed by the connecting column 3 and retract into their corresponding installation grooves to avoid contact. After the lower end of the sliding sleeve 4 is tightly fitted against the upper end of the connecting column 3, the construction personnel will then remove the torsion sleeve 81. Rotating 45 degrees causes the torsion sleeve 81 to simultaneously rotate several clamping plates 83 by 45 degrees. Under the action of the compression spring, the clamping plates 83 extend out of their respective installation grooves and insert into their respective slots, thus achieving a quick snap-fit ​​between the torsion sleeve 81 and the docking column 3. Afterward, the construction personnel use the fastening components of the clamp 82 to control the clamp 82 to lock and tightly fit onto the outer wall of the corresponding pre-embedded support body 1 for fastening installation. This further enhances the connection stability between the photovoltaic bracket and the pre-embedded support body 1. The installation method of quick snap-fit ​​between the torsion sleeve 81 and the docking column 3, and further locking connection with the clamp 82, can ensure the coaxiality of the photovoltaic bracket and the pre-embedded support body 1 while allowing for quick and convenient installation. This avoids the problems of difficult coaxiality calibration between the conventional photovoltaic bracket and the pre-embedded support body 1, high labor costs, and cumbersome, time-consuming, and labor-intensive installation steps.

[0053] It should also be noted that after several photovoltaic brackets are installed, the construction personnel need to fasten several guide rods 71 ​​to the connecting sleeve plate 744 in sequence using bolts (not shown in the figure) and other connecting parts, so that they can move synchronously with the connecting sleeve plate 744, which facilitates the subsequent angle adjustment of the photovoltaic panel body 6.

[0054] During the photovoltaic panel body 6 installation stage, the construction personnel then connect the support shaft 9 by passing it through several purlin support plates 73 in sequence. During this process, the construction personnel can manually adjust the angles of the other photovoltaic brackets to ensure the smooth installation of the support shaft 9. Removable limiting rings are fitted on both the left and right ends of the support shaft 9. The support shaft 9 can enhance the connection strength and stability between several purlin support plates 73, and the limiting rings can prevent the support shaft 9 from falling off the purlin support plates 73, ensuring the reliability of the entire photovoltaic bracket structure.

[0055] Subsequently, the two electric push rods 745 on the left and right sides work together to move the connecting sleeve 744 synchronously upward or downward. Since the sliding sleeves 4 on several photovoltaic brackets are at the same horizontal height at this time, and the positions of several support plates 5, torsion sleeves 81 and clamps 82 are fixed, the connecting sleeve 744 will drive several photovoltaic brackets to move synchronously upward or downward. During this period, under the coordinated action of the front diagonal brace 741, diagonal brace sleeve 742 and rear diagonal brace 743, the photovoltaic brackets will jointly drive the corresponding purlin support plate 73 to perform adaptive rotation compensation around the support shaft 9. The tilt angle of the purlin support plate 73 will also change accordingly until the tilt angle of several purlin support plates 73 is in a position that facilitates the installation of photovoltaic panels. At the angle of the main body 6, the two electric push rods 745 on the left and right are stopped. Then, the construction personnel slide the two purlins 731 through and install them on the front and rear sides of the upper end of several purlin support plates 73, until several strong magnets 732 on the purlins 731 are magnetically connected to the corresponding purlin support plates 73 for preliminary positioning and connection. This facilitates installation and disassembly while ensuring the stability of the connection. Finally, the construction personnel place several photovoltaic panel bodies 6 on several purlin support plates 73 and purlins 731 in sequence, and use connectors to fasten the photovoltaic panel bodies 6 to the corresponding purlin support plates 73 and purlins 731 in sequence, so that several photovoltaic panel bodies 6 are stably installed on purlin support plates 73.

[0056] During the tilt angle adjustment stage of the photovoltaic panel body 6, it should be noted that the photovoltaic panel body 6 is initially tilted. At this time, several rear diagonal braces 743 are initially retracted into their corresponding receiving grooves, and the telescopic ends of the two left and right electric push rods 745 are retracted. The connecting sleeve 744 and several sliding sleeves 4 are all located at the bottom. Since the power generation of the photovoltaic panel body 6 directly depends on the intensity of solar radiation it receives, in order to maximize the reception of solar radiation energy and thus improve the power generation efficiency, it is usually necessary to adjust the tilt angle of the photovoltaic panel body 6.

[0057] The two electric push rods 745 on the left and right sides work together to move the connecting sleeve 744 upwards synchronously. The connecting sleeve 744 will simultaneously move several guide rods 71 ​​upwards synchronously. Similarly, since the sliding sleeves 4 on several photovoltaic brackets are at the same horizontal height, and the positions of several support plates 5, torsion sleeves 81, and clamps 82 are fixed, the connecting sleeve 744 will move several photovoltaic brackets upwards synchronously. During this process, under the combined action of the front diagonal brace 741, diagonal brace sleeve 742, and rear diagonal brace 743, the photovoltaic brackets will jointly drive the corresponding purlin support plate 73 to perform adaptive rotation compensation around the support shaft 9. The tilt angle of the purlin support plate 73 will also change accordingly until several purlin support plates 73 drive the corresponding photovoltaic brackets. The photovoltaic panel body 6 rotates synchronously at the corresponding angle to ensure that sunlight shines as perpendicularly as possible onto the surfaces of several photovoltaic panels 6, thereby improving power generation efficiency. During this process, the rear diagonal brace 743 will gradually extend the corresponding diagonal brace sleeve 742 for stroke compensation. The angles between the front diagonal brace 741, the diagonal brace sleeve 742, and the rear diagonal brace 743 and the corresponding guide rod 71 and purlin support plate 73 will also be adaptively compensated to ensure the stability of the photovoltaic support. By using the cooperation of the front diagonal brace 741, the rear diagonal brace 743, and the diagonal brace sleeve 742, the tilt angle of the purlin support plate 73 and the photovoltaic panel body 6 can be freely adjusted to adapt to different lighting conditions, thereby improving the power generation efficiency of the photovoltaic panel and the overall structural stability of the photovoltaic support.

[0058] During maintenance and replacement, if the photovoltaic bracket and photovoltaic panel body 6 need to be disassembled and replaced after long-term use, the construction personnel shall first use the connectors to loosen the fastening connections between several photovoltaic panel bodies 6 and the corresponding purlin support plates 73 and purlins 731, and then remove several photovoltaic panel bodies 6, support shafts 9 and two purlins 731 in sequence. Several guide rods 71 ​​and connecting sleeve plates 744 (bolts not shown in the figure) also need to be removed to loosen the fastening connections. Then, the construction personnel shall rotate the torsion sleeve 81 45 degrees in the opposite direction. At this time, the torsion sleeve 81 will simultaneously drive several clamping plates 83 to rotate 45 degrees in the opposite direction. The clamping plates 83 will be simultaneously subjected to the pressing force of the connecting column 3 and will then disengage. Simultaneously, the corresponding slot retracts into the corresponding installation groove, thereby achieving the effect of quickly releasing the locking between the twist sleeve 81 and the docking column 3. Then, the construction personnel control the clamp 82 to release the locking and loosen the outer wall of the corresponding pre-embedded support body 1 through the fastening components of the clamp 82. Several photovoltaic brackets composed of the sliding sleeve 4, support plate 5, angle adjustment part 7 and installation alignment part 8 can be taken out one by one and replaced. Finally, the above installation steps are repeated to install the new photovoltaic panel body 6 and photovoltaic bracket. This can achieve quick and convenient disassembly of the photovoltaic panel body 6 and photovoltaic bracket, and can avoid the problems of bolt stripping, photovoltaic bracket deformation, and increased replacement costs caused by the conventional bolt fixing method and secondary disassembly and assembly.

[0059] In summary, this application has the following advantages:

[0060] Advantage 1: During the installation of the sliding sleeve 4, the construction personnel first movably mount the connecting sleeve 744 onto the outer wall of several pre-embedded support bodies 1, and then fix the telescopic ends of the two left and right electric push rods 745 onto the connecting sleeve 744 in sequence. Then, the construction personnel movably mount the pre-prepared photovoltaic bracket onto the outer wall of the corresponding pre-embedded support body 1 in sequence. During this process, several ball bearings 10 can reduce the friction between the sliding sleeve 4 and the connecting sleeve 744 and the pre-embedded support body 1, so that it can slide up and down smoothly along the outer wall of the pre-embedded support body 1 for installation.

[0061] Secondly, specifically, when the torsion sleeve 81 is movably fitted onto the outer wall of the docking column 3, several locking plates 83 will retract into their respective installation grooves to avoid obstruction. After the lower end of the sliding sleeve 4 is tightly fitted against the upper end of the docking column 3, the construction personnel will rotate the torsion sleeve 81 by 45 degrees. At this time, the torsion sleeve 81 will simultaneously drive several locking plates 83 to rotate synchronously by 45 degrees, and the locking plates 83 will be inserted into their respective slots, thereby achieving the effect of quick engagement between the torsion sleeve 81 and the docking column 3. Afterwards, the construction personnel will control the clamp 82 to lock and tighten it securely. The photovoltaic bracket is fastened to the outer wall of the corresponding pre-embedded support body 1 to further enhance the connection stability between the photovoltaic bracket and the pre-embedded support body 1. The installation method of quick snap-fitting with twist sleeve 81 and docking column 3 and further locking connection with clamp 82 can quickly and conveniently carry out the installation work while ensuring the coaxiality of the photovoltaic bracket and the pre-embedded support body 1. It avoids the problems of difficult coaxiality calibration between the conventional photovoltaic bracket and the pre-embedded support body 1, high labor cost, and cumbersome, time-consuming and labor-intensive installation work.

[0062] Thirdly, during the installation of the photovoltaic panel body 6, the construction personnel will then connect the support shaft 9 by passing it through several purlin support plates 73 in sequence. Removable limiting rings are fitted on both the left and right ends of the support shaft 9. The support shaft 9 can enhance the connection strength and stability between several purlin support plates 73, and the limiting rings can prevent the support shaft 9 from falling off the purlin support plates 73, thus ensuring the reliability of the entire photovoltaic support structure.

[0063] Fourthly, the two electric push rods 745 on the left and right sides are then controlled to drive the connecting sleeve plate 744 to move synchronously upward or downward. The connecting sleeve plate 744 will drive several photovoltaic brackets to move synchronously upward or downward. The purlin support plate 73 will perform adaptive rotation compensation around the support shaft 9 until the tilt angle of several purlin support plates 73 is at an angle that is convenient for installing the photovoltaic panel body 6. Then, the construction personnel will slide two purlins 731 through and install them on the front and rear sides of the upper end of several purlin support plates 73 in sequence until several strong magnets 732 on the purlins 731 are magnetically attracted and connected to the corresponding purlin support plates 73 for preliminary positioning and connection. This facilitates installation and disassembly while ensuring the stability of the connection.

[0064] Fifthly, during the tilt angle adjustment stage of the photovoltaic panel body 6, the two electric push rods 745 on the left and right sides work together to drive the connecting sleeve plate 744 to move upward synchronously. The connecting sleeve plate 744 will drive several photovoltaic brackets to move upward synchronously. The photovoltaic brackets will then drive the corresponding purlin support plate 73 to perform adaptive rotation compensation around the support shaft 9, until several purlin support plates 73 drive the corresponding photovoltaic panel body 6 to rotate synchronously at the corresponding angle. This allows sunlight to shine as perpendicularly as possible onto the surface of several photovoltaic panel bodies 6, which is conducive to improving power generation efficiency. By using the cooperation of the front inclined support rod 741, the rear inclined support rod 743, and the inclined support sleeve rod 742, the tilt angle of the purlin support plate 73 and the photovoltaic panel body 6 can be freely adjusted to adapt to different lighting conditions, improve the power generation efficiency of the photovoltaic panel, and enhance the overall stability of the photovoltaic bracket structure.

[0065] Advantage 6: During maintenance and replacement, if the photovoltaic bracket and photovoltaic panel body 6 need to be disassembled and replaced after long-term use, the construction personnel first remove several photovoltaic panel bodies 6, support shafts 9, and two purlins 731 in sequence. Then, the construction personnel rotate the torsion sleeve 81 in the opposite direction by 45 degrees. At this time, the torsion sleeve 81 will simultaneously drive several clamping plates 83 to rotate in the opposite direction by 45 degrees. The clamping plates 83 will exit from their corresponding slots and retract into their corresponding installation grooves, thereby achieving the effect of quickly releasing the clamping between the torsion sleeve 81 and the connecting column 3. Then, the construction personnel control the clamp 82 to release the lock and loosen the outer wall of the corresponding pre-embedded support body 1. Then, several photovoltaic brackets composed of sliding sleeves 4, support plates 5, angle adjustment parts 7, and installation alignment parts 8 can be taken out one by one for replacement. This can achieve quick and convenient disassembly of photovoltaic panel bodies 6 and photovoltaic brackets, and can avoid the problems of bolt stripping, photovoltaic bracket deformation, and increased replacement costs caused by the conventional bolt fixing method and secondary disassembly and assembly.

[0066] Referring to Figure 1, the present invention also provides a photovoltaic support foundation construction method based on adaptive adjustment, which is completed using a photovoltaic support foundation construction device based on adaptive adjustment, and includes the following steps:

[0067] S1: During the installation of the sliding sleeve 4, the connecting sleeve 744 is first movably fitted onto the outer wall of several pre-embedded support body 1, and then the pre-prepared photovoltaic bracket is movably fitted onto the outer wall of the corresponding pre-embedded support body 1.

[0068] S2: During the installation of the torsion sleeve 81, the torsion sleeve 81 is movably fitted onto the outer wall of the docking column 3, so that several clamping plates 83 are inserted into the corresponding clamping slots respectively, and the clamping clamp 82 is controlled to lock and tightly fit onto the outer wall of the corresponding pre-embedded support body 1 for fastening installation.

[0069] S3: During the installation stage of the photovoltaic panel body 6, the support shaft 9 is installed in sequence and the two purlins 731 are initially positioned and connected. Several photovoltaic panel bodies 6 are placed on several purlin support plates 73 and purlins 731 in sequence, and several photovoltaic panel bodies 6 are then securely installed on the purlin support plates 73 in sequence.

[0070] S4: During the tilt angle adjustment stage of the photovoltaic panel body 6, the connecting sleeve 744 is controlled to move up or down, thereby driving several photovoltaic supports to move up or down synchronously, until several purlin support plates 73 drive the corresponding photovoltaic panel body 6 to rotate synchronously at the corresponding angle for adjustment.

[0071] S5: During the maintenance and replacement phase, remove several photovoltaic panel bodies 6, support shafts 9 and two purlins 731 in sequence. Then, release the locking effect between the torsion sleeve 81 and the docking column 3, and control the clamp 82 to release the locking and loosen the outer wall of the corresponding pre-embedded support body 1. Then, several photovoltaic brackets can be removed in sequence for replacement.
