[0002] Currently, the main method for connecting precast concrete pipe piles to the bearing platform is to insert a steel reinforcement cage into the inner cavity of the pipe pile and then pour slightly expanding concrete to form core-filled concrete. However, due to the inability to ensure the compaction degree and pouring quality of the core-filled concrete, the connection strength between the precast concrete pipe pile and the bearing platform is insufficient, resulting in engineering problems such as the core-filled concrete being pulled out, which affects the anti-pull quality, endangers the safety of the building, and poses potential safety hazards. Therefore, there is room for improvement. Summary of the Utility Model

[0003] This application aims to at least solve the technical problem in the related art that it is difficult to ensure the connection strength between precast concrete pipe piles and the bearing platform. To this end, this application proposes a support device, a photovoltaic support, and a photovoltaic system, which can change the connection method between the pile foundation and the bearing platform and improve the connection strength between the pile foundation and the bearing platform.

[0004] In a first aspect, this application provides a support device applied to a photovoltaic support, including:

[0008] The adapter, the pile foundation, and the bearing platform together form a support device, providing a stable and safe support structure for the photovoltaic support, ensuring the efficient and reliable operation of the photovoltaic system. At the same time, by setting an adapter at the top of the pile foundation, the connection method between the pile foundation and the bearing platform can be changed, improving the connection strength between the pile foundation and the bearing platform, thereby improving the reliability of the connection between the pile foundation and the bearing platform.

[0009] According to an embodiment of this application, the inner wall of the installation groove is provided with a protruding first connecting rib, and the second protruding portion includes a second connecting rib, and the second connecting rib is connected to the first connecting rib.

[0011] According to an embodiment of the present application, the second protruding portion is provided with a third protruding portion that is cross-connected to the second protruding portion.

[0012] The cross-connection design of the second protruding portion and the third protruding portion on the adapter can enhance the structural strength of the adapter, provide additional connection points and fixing mechanisms, and ensure the stability and safety of the support device under various environmental conditions.

[0013] According to an embodiment of the present application, concrete is filled between the adapter and the inner wall of the installation groove, and the second protruding portion is buried in the concrete.

[0042] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0043] The present application aims to solve at least the technical problem that it is difficult to ensure the connection strength between precast concrete pipe piles and the bearing platform in the related art. For this purpose, the present application proposes a support device, a photovoltaic bracket and a photovoltaic system, which can change the connection mode between the pile foundation and the support platform and improve the connection strength between the pile foundation and the support platform.

[0044] The following refers to Figures 1 - 3 Describe the support device 1 according to the embodiment of the present application.

[0045] As Figure 1 shown, the support device 1 includes: an adapter 10, a pile foundation 20 and a support platform 30. Among them, the adapter 10 is a key component in the support device 1 for connecting the pile foundation 20 and the support platform 30. It usually has a specific shape and interface to firmly connect the pile foundation 20 and the support platform 30 together to form a stable support structure, playing a role in transmitting loads and enhancing the structural stability. The pile foundation 20 is the basic part of the support device 1, usually buried deep in the ground to provide sufficient bearing capacity and stability, bearing all the weight and load from the photovoltaic bracket and firmly fixing the photovoltaic bracket on the ground to ensure the safe and reliable operation of the photovoltaic system. The support platform 30 is the platform part of the support device 1 for supporting and fixing the photovoltaic bracket, and is used to accommodate and fix the adapter 10 and the pile foundation 20.

[0046] The adapter 10 is designed to be tubular, having a first protruding portion 110 protruding inward and a second protruding portion 120 protruding outward, forming certain protrusions on the inner wall and outer wall of the tubular structure respectively. The pile foundation 20 can be a precast pile, such as a concrete pile, a steel pipe pile, etc. The adapter 10 is sleeved outside the pile foundation 20, and the first protruding portion 110 is located inside the pile foundation 20. By increasing the contact area and friction with the pile foundation 20, the connection stability between the adapter 10 and the pile foundation 20 is improved. At the same time, it can also play a role of positioning or guiding to ensure that the adapter 10 can be correctly sleeved on the pile foundation 20. The support platform 30 is usually designed with an installation groove 310 for accommodating and fixing the adapter 10, and the second protruding portion 120 is connected to the support platform 30, serving as the main connection point between the adapter 10 and the support platform 30, so that the support platform 30 can be stably fixed on the adapter 10 and achieve a firm connection through the second protruding portion 120, forming a stable support system.

[0047] It can be understood that the adapter 10, the pile foundation 20 and the support platform 30 together constitute the support device 1, providing a stable and safe support structure for the photovoltaic bracket, ensuring that the photovoltaic system can operate efficiently and reliably. At the same time, by reasonably selecting and installing the adapter 10, it can be ensured that the photovoltaic modules can receive solar radiation at a predetermined angle and direction, thereby improving the power generation efficiency of the photovoltaic system.

[0048] During the actual working process, the second protruding portion 120 of the adapter 10 can be first aligned with the installation groove 310 of the support platform 30 and installed in place, and then concrete is filled between the inner wall of the adapter 10 and the installation groove 310 to bury the second protruding portion 120 in the concrete to form an integral body. Then, the bottom of the pile foundation 20 is deeply buried in the ground and fixed to ensure its stability and bearing capacity. Then, the integral structure formed after connecting the adapter 10 and the installation groove 310 is sleeved on the top of the pile foundation 20, and the pile foundation 20 is driven into the adapter 10 by preloading or hammering, so that the first protruding portion 110 is located inside the pile foundation 20 to enhance the connection strength. After successfully installing the support device 1, the photovoltaic bracket is installed on the support platform 30 and fixed at a predetermined position.

[0049] It is also possible to first drive the pile foundation 20 into the adapter 10 by preloading or hammering, so that the first protruding portion 110 is located inside the pile foundation 20 to enhance the connection strength and form an integral body. Then, the second protruding portion 120 of the adapter 10 is aligned with the installation groove 310 of the support platform 30 and installed in place, and then concrete is filled between the inner wall of the adapter 10 and the installation groove 310 to bury the second protruding portion 120 in the concrete. Then, the bottom of the pile foundation 20 of the assembled support device 1 is deeply buried in the ground and fixed. Finally, the photovoltaic bracket is installed on the support platform 30 and fixed at a predetermined position, providing stable and reliable support to ensure the normal operation of the photovoltaic system.

[0050] In the related art, the precast concrete pile foundation 20 and the support platform 30 are mainly connected by inserting a steel cage into the inner cavity of the pile foundation 20 and then pouring micro-expansive concrete to form core-filled concrete. However, since the density and quality of the core-filled concrete cannot be guaranteed, the connection strength between the precast concrete pile foundation 20 and the support platform 30 is insufficient, and engineering problems such as the core-filled concrete being pulled out may occur, which affect the pull-out resistance quality. The inventors set an adapter 10 on the top of the pile foundation 20 to change the connection method between the pile foundation 20 and the support platform 30, thereby improving the connection strength between the concrete pile foundation 20 and the support platform 30.

[0051] According to the support device 1 provided in the embodiment of the present application, the adapter 10, the pile foundation 20 and the support platform 30 together constitute the support device 1, which provides a stable and safe support structure for the photovoltaic bracket, ensuring that the photovoltaic system can operate efficiently and reliably. At the same time, by arranging the adapter 10 on the top of the pile foundation 20, the connection method between the pile foundation 20 and the support platform 30 can be changed, and the connection strength between the pile foundation 20 and the support platform 30 can be improved, thereby improving the reliability of the connection between the pile foundation 20 and the support platform 30.

[0052] In some embodiments, Figures 1 - 3 As shown, the inner wall of the mounting groove 310 is provided with a protruding first connecting rib 320, and the second protruding portion 120 includes a second connecting rib 121, which is connected to the first connecting rib 320, and can enhance the connection strength and stability between the support platform 30 and the adapter 10.

[0053] The inner wall of the mounting groove 310 is provided with a protruding first connecting rib 320, the main function of which is to provide an additional contact point and a locking mechanism to ensure that the adapter 10 can be firmly positioned in the mounting groove 310 and prevent sliding or rotation. The second protrusion 120 is located on the outer wall of the adapter 10, including a second connecting rib 121. The second connecting rib 121 can be connected to the first connecting rib 320 so that it can fit tightly during the installation process and interact with the first connecting rib 320 to make the connection between the support platform 30 and the adapter 10 more secure.

[0054] During the installation process, the adapter 10 is inserted into the installation groove 310 of the support platform 30 until the second connecting rib 121 meets and docks with the first connecting rib 320. After the second connecting rib 121 docks with the first connecting rib 320, further fixed connection can be achieved through appropriate fastening methods, such as welding or sleeve connection, to ensure that the connection part can remain stable and not loose when subjected to external force.

[0055] It can be understood that by the tight fit between the first connecting ribs 320 on the inner wall of the installation groove 310 and the second connecting ribs 121 on the outer wall of the adapter 10, the connection strength between the support platform 30 and the adapter 10 can be enhanced, making the entire support device 1 more stable and reliable, and the installation process can be simplified without additional fasteners or complex operation steps.

[0056] In some embodiments, the second protrusion 120 is provided with a third protrusion that cross-connects with the second protrusion 120.

[0057] The second protrusion 120 of the adapter 10, as the main part connected to the support platform 30, can be designed in the form of a rib plate, and the rib plate can provide an additional support surface. The second protrusion 120 is provided with a third protrusion that cross-connects with the second protrusion 120. The third protrusion is arranged on the second protrusion 120 in the form of a stud, and the connection method can be welding, riveting or threaded connection, etc., for enhancing the grip effect with the concrete. At the same time, a stable frame structure is formed through the cross-connection method, dispersing the stress and load on the adapter 10, which can enhance the overall rigidity and torsional resistance of the adapter 10, and help reduce the risk of deformation or damage caused by unidirectional stress.

[0058] One end of the second protrusion 120 can be provided with a enlarged head. The enlarged head is a structure with a locally increased size, similar to an enlarged head or protrusion, which can play an anti-overturning role during the construction process and further enhance the anchoring effect of the pile top after completion.

[0059] During the construction process, the enlarged head can serve as a temporary support point or stabilizer to prevent the adapter 10 from overturning or sliding during the installation process, which helps to ensure the safety and smooth progress of the construction. After the support device 1 is installed, the enlarged head can be further embedded in the concrete filled between the support platform 30 and the pile foundation 20, thereby enhancing the anchoring effect of the pile foundation 20 and helping to improve the stability and bearing capacity of the support device 1.

[0060] It can be understood that the cross-connection design of the second protrusion 120 and the third protrusion on the adapter 10 can enhance the structural strength of the adapter 10, provide additional connection points and fixing mechanisms, and ensure the stability and safety of the support device 1 under various environmental conditions.

[0061] In some embodiments, concrete is filled between the adapter 10 and the inner wall of the installation groove 310, and the second protrusion 120 is buried in the concrete, which can enhance the connection stability and overall structural strength between the adapter 10 and the installation groove 310.

[0062] The concrete filled between the adapter 10 and the inner wall of the installation groove 310 can form a solid whole, eliminating the gap between the two, reducing the risk of connection failure caused by loosening or vibration. Moreover, the adhesive force of the concrete can firmly connect the adapter 10 and the support platform 30 together, improving the stability of the connection. At the same time, as a high-strength material, the concrete can significantly enhance the overall structural strength of the support device 1. When the second protruding portion 120 of the adapter 10 is buried in the concrete, the second protruding portion 120 is additionally reinforced, enabling it to withstand greater loads and stresses. The concrete filling can also play a role in resisting environmental factors such as wind, rain, corrosion, etc., protecting the adapter 10 and the support platform 30 from external environmental erosion and extending the service life of the support device 1.

[0063] During the actual working process, the adapter 10 and the support platform 30 are correctly installed and positioned, and then the inner wall of the installation groove 310 and the outer wall of the adapter 10 are cleaned to remove impurities and oil stains to ensure that the concrete can bond fully. Then, the mixed concrete is filled into the gap between the adapter 10 and the inner wall of the installation groove 310. During the filling process, a vibrator or a similar tool can be used for vibration to remove the air bubbles in the concrete and ensure its density. While filling the concrete, the second protruding portion 120 of the adapter 10 is completely buried in the concrete so that the second protruding portion 120 forms a tight bond with the concrete, further enhancing the stability of the connection.

[0064] It can be understood that filling the concrete between the adapter 10 and the inner wall of the installation groove 310 and burying the second protruding portion 120 in the concrete can effectively enhance the connection stability and structural strength of the support device 1.

[0065] In some embodiments, as Figure 3 shown, the first protruding portion 110 includes a first rib plate 111 protruding from the inner wall of the adapter 10.

[0066] The first protruding portion 110 is located on the inner wall of the adapter 10, that is, on the side facing the pile foundation 20, and includes the first rib plate 111. The first rib plate 111 protrudes in the form of a plate-like structure, which can be a plurality of parallel plate-like structures distributed along the circumferential direction of the tubular adapter 10, and the cross-section of the plate-like structure along the axial direction of the adapter 10 is rectangular to meet the connection requirements with the pile foundation 20.

[0067] The first protruding portion 110 can improve the connection stability between the adapter 10 and the pile foundation 20 by increasing the contact area and friction force with the pile foundation 20, helping to prevent the adapter 10 from sliding or loosening on the pile foundation 20. The first protruding portion 110 can also play a role in positioning and guiding to ensure that the adapter 10 can be correctly sleeved on the pile foundation 20 and maintain a stable installation position.

[0068] In some embodiments, as Figure 3 shown, the second protruding portion 120 includes a second rib plate 122 protruding from the outer wall of the adapter 10.

[0069] The second protruding portion 120 is located on the outer wall of the adapter 10, that is, on the side facing the support platform 30, and includes a second rib plate 122. The second rib plate 122 also protrudes in the form of a plate structure, but its shape and size are different from those of the first protruding portion 110. The second protruding portions 120 are also a plurality of parallel plate structures distributed along the circumferential direction of the tubular adapter 10, but the cross-section of the plate structure along the axial direction of the adapter 10 is trapezoidal to adapt to the connection requirements with the support platform 30.

[0070] The second protruding portion 120 is the main connection point between the adapter 10 and the support platform 30. The support platform 30 can be firmly fixed to the adapter 10 by being embedded in the mounting groove 310, connected to the first connecting rib 320 or other means. As an outwardly protruding plate structure, the second protruding portion 120 can also enhance the overall structural strength of the adapter 10, and to a certain extent, resist external loads and stresses, protecting the adapter 10 from damage.

[0071] It can be understood that setting the first protruding portion 110 and the second protruding portion 120 as plate structures protruding from the wall surface of the adapter 10 can improve the connection stability and structural strength between the adapter 10 and the pile foundation 20 and the support platform 30 respectively, and can also ensure the overall stability and reliability of the support device 1, and effectively resist the influence of external environmental factors, ensuring the normal operation of the photovoltaic system.

[0072] In some embodiments, as Figure 3 shown, the cross-sectional area of the second protruding portion 120 gradually increases from one end to the other end.

[0073] The second protruding portions 120 are evenly distributed on the outer wall surface of the tubular adapter 10, and the cross-section along the axial direction of the adapter 10 is trapezoidal. The trapezoidal cross-section can provide a larger embedding area when the second protruding portion 120 is connected to the mounting groove 310. As the cross-sectional area gradually increases, the embedding force is also correspondingly enhanced, thereby improving the connection stability and reliability. At the same time, when bearing an external load, the trapezoidal cross-section can effectively disperse the stress, reduce the risk of local stress concentration, and improve the overall load-bearing capacity of the adapter 10.

[0074] In a photovoltaic system, the adapter 10 and the support structure may need to resist the overturning moment caused by wind force and other external factors. The trapezoidal cross-section design can increase the stability of the second protrusion 120 in the vertical direction, reduce loosening or damage caused by the overturning moment. At the same time, the inclined surface on the second protrusion 120 can serve as a guiding structure, playing a guiding and positioning role during the installation process, ensuring that the adapter 10 is accurately inserted into the installation groove 310 and achieving a tight connection with other structures.

[0075] It can be understood that the second protrusion 120 with a trapezoidal cross-section design can enhance the anchoring and bearing capacity, thereby improving the overall performance and reliability of the support device 1 and ensuring the stable operation of the photovoltaic system.

[0076] In some embodiments, as Figure 3 shown, the first protrusion 110 is radially aligned with one of the second protrusions 120 along the adapter 10.

[0077] The radial alignment of the first protrusion 110 and the corresponding second protrusion 120 can reduce the gaps and misalignments during the connection process, improve the stability and reliability of the connection. And in the photovoltaic system, the adapter 10 needs to bear various loads from the photovoltaic modules and the photovoltaic brackets. When the first protrusion 110 and the second protrusion 120 are radially aligned, these loads can be more effectively transmitted and dispersed, balancing the forces on the adapter 10 in different directions, thereby reducing the risk of deformation or damage caused by uneven stress distribution, helping to reduce local stress concentration, improving the overall bearing capacity of the adapter 10. The radially aligned design can also simplify the installation process of the adapter 10, ensure the accurate docking between the first protrusion 110 and the second protrusion 120, and contribute to improving the construction efficiency.

[0078] It can be understood that the radial alignment of the first protrusion 110 and one of the second protrusions 120 along the adapter 10 can balance the forces on the adapter 10 in different directions, help reduce local stress concentration, and improve the overall bearing capacity of the adapter 10.

[0079] In some embodiments, as Figure 3 shown, the first protrusion 110 includes a plurality of circumferentially spaced apart around the adapter 10, and the second protrusion 120 includes a plurality of circumferentially spaced apart around the adapter 10.

[0080] A plurality of first protruding portions 110 are arranged at a certain angle along the circumferential direction of the adapter 10, and this angle can be between 30° and 45°, so as to increase the contact area and connection points between the adapter 10 and the pile foundation 20, which helps to disperse stress, improve the stability and reliability of the connection, and enhance the positioning ability of the adapter 10 on the pile foundation 20, ensuring a tight connection and stable support with the pile foundation 20. The outer ribs of the adapter are provided with outwardly extending stiffening rib plates at intervals.

[0081] A plurality of second protruding portions 120 are arranged at a certain angle along the circumferential direction of the adapter 10, and this angle can be between 30° and 45°, so as to provide more support points and connection surfaces, which helps to enhance the connection strength between the adapter 10 and the support platform 30, improve the bearing capacity and stability of the support device 1. When bearing an external load, the plurality of second protruding portions 120 can more effectively disperse stress, reduce the risk of local stress concentration, help to extend the service life of the adapter 10 and the support device 1, and reduce the risk of damage caused by excessive stress.

[0082] It can be understood that the first protruding portions 110 and the second protruding portions 120 can be arranged at intervals along the circumferential direction of the adapter 10 separately, or they can both be arranged at intervals along the circumferential direction of the adapter 10. When both the first protruding portions 110 and the second protruding portions 120 are arranged at intervals along the circumferential direction of the adapter 10, combining the advantages of the separate arrangements of the first protruding portions 110 and the second protruding portions 120, the adapter 10 can have higher structural strength and connection stability, and can better adapt to complex and changeable application scenarios and load conditions.

[0083] Next, the embodiments of the present application will be specifically described from three different implementation perspectives.

[0084] I. The second protruding portion 120 protruding outward from the adapter 10 includes a second connecting rib 121

[0085] The second protruding portion 120 is located on the outer wall of the adapter 10 and includes a second connecting rib 121. The second connecting rib 121 can be connected to the first connecting rib 320 so as to be closely matched during the installation process and interact with the first connecting rib 320 to make the connection between the support platform 30 and the adapter 10 more firm.

[0086] During the installation process, the adapter 10 is inserted into the installation groove 310 of the support platform 30 until the second connecting rib 121 meets and docks with the first connecting rib 320. After the second connecting rib 121 and the first connecting rib 320 are docked, further fixed connection can be achieved through appropriate fastening methods, such as welding or sleeve connection, to ensure that the connection part remains stable and does not loosen when subjected to external forces.

[0087] II. The second protruding part 120 protruding outward from the adapter 10 includes a second rib plate 122

[0088] The second protruding part 120 is located on the outer wall of the adapter 10 and includes a second rib plate 122. The second rib plate 122 is a plurality of parallel plate-like structures distributed along the circumferential direction of the tubular adapter 10, and the cross-sectional area of the second rib plate 122 gradually increases from one end to the other end to meet the connection requirements with the support platform 30.

[0089] The second rib plate 122 is the main connection point between the adapter 10 and the support platform 30. During the installation process, the adapter 10 is inserted into the installation groove 310 of the support platform 30, and the second rib plate 122 can be connected to the first connecting rib 320 by welding. As an outwardly convex plate-like structure, the second protruding part 120 can also enhance the overall structural strength of the adapter 10 and resist external loads and stresses to a certain extent, protecting the adapter 10 from damage.

[0090] III. The second protruding part 120 protruding outward from the adapter 10 includes a second connecting rib 121 and a second rib plate 122

[0091] The second protruding part 120 is located on the outer wall of the adapter 10 and includes a second connecting rib 121 and a second rib plate 122. The second connecting rib 121 can be connected to the first connecting rib 320 so as to be closely matched during the installation process and interact with the first connecting rib 320 to make the connection between the support platform 30 and the adapter 10 more firm.
