Description

An end support structure and a flexible photovoltaic support system

[0001] This application claims priority to Chinese Patent Application No. 202411456515.2, filed on October 18, 2024, entitled "An End Support Structure and Flexible Photovoltaic Support System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of photovoltaic technology, and in particular to an end support structure and a flexible photovoltaic support system. Background Technology

[0003] A cable-stayed photovoltaic (PV) support structure is a type of support frame for solar power plant modules. It mainly consists of end supports, a central support, and the supporting central cables and wind-resistant system. The end supports, as crucial components supporting the main cables, primarily constrain both ends of the main cables and provide the tensioning conditions for prestressing. The end supports typically consist of columns, compression piles, tie rods, and tension piles. The columns, through pin joints at their heads, convert the tension of the main cables into the diagonal tension of the tie rods, and the lower ends of the tie rods are connected to the tension piles.

[0004] In the existing technology, the end support usually has two columns, which are connected to the main cable through the column head pin node respectively. However, since the two columns are independent of each other, the wind resistance and stability of the entire end support are poor, and its adaptability to complex terrain is weak. At the same time, its unstable installation structure will also cause certain risks during the tensioning of the main cable.

[0005] In addition, the column head is usually fixed at the top of the column by welding or bolting. The column head is then connected to the connecting components of the main cable and the cable tie. This connection method usually requires processing such as cutting steel plates, bolting, and welding steel plates. The manufacturing process is relatively complex and involves a large number of parts, resulting in low assembly quality and efficiency, and high cost.

[0006] Therefore, how to improve the assembly efficiency of the end bracket while ensuring its stability has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the purpose of this application is to provide an end bracket structure that improves the assembly efficiency of the end bracket while ensuring the stability of the end bracket.

[0008] Another objective of this application is to provide a flexible photovoltaic support system having the aforementioned end support structure.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] An end support structure, comprising:

[0011] A connecting assembly includes a main shaft and a limiting member. The main shaft is used for the main cable to pass through, and the limiting member is sleeved on the outside of the main cable to prevent the main cable from coming off the main shaft. The main shaft has a limiting notch that cooperates with the limiting member. The bottom wall of the limiting notch is a plane so that the limiting member abuts against the bottom wall of the limiting notch.

[0012] The column has a mounting cavity for accommodating the connecting assembly. The two opposite side walls of the mounting cavity have through holes for the main shaft to pass through. Both ends of the main shaft pass through the through holes and are locked by safety pins.

[0013] There are two columns, and at least two reinforcing members are connected between the two columns, with the two reinforcing members intersecting at a preset angle.

[0014] Optionally, in the above-described end support structure, the reinforcing member is movably connected to the column, and a locking mechanism is provided between the reinforcing member and the column, the locking mechanism being used to lock the connection between the reinforcing member and the column.

[0017] Optionally, in the above-described end bracket structure, there are multiple first mounting holes and multiple second mounting holes, and in the height direction of the column, the number of first mounting holes is greater than the number of second mounting holes.

[0018] Optionally, in the above-described end support structure, the connecting sleeve is a U-shaped structure, and the connecting sleeve has an opening for connecting with the column, and the reinforcing member is hinged to the side of the connecting sleeve opposite to the opening.

[0019] Optionally, the above-described end support structure includes a diagonal brace, which is rotatably connected to the main shaft via a diagonal sleeve. Optionally, in the above-described end support structure, the diagonal sleeve includes a connecting plate and two hinge bolts. The two hinge bolts are symmetrically arranged on the connecting plate and locked to it, and the open ends of the two hinge bolts are symmetrically sleeved at both ends of the main shaft.

[0020] Optionally, the above-mentioned end support structure further includes a first pile body and a second pile body, the column is disposed on the first pile body, the inclined tie is fixed on the second pile body, and the first pile body and the second pile body are connected by a reinforcing beam.

[0021] Optionally, in the above-described end bracket structure, the limiting member includes an end head, which is a stepped structure, and the small-diameter end of the end head is used to abut against the bottom wall of the limiting notch, while the large-diameter end of the end head is exposed in the mounting cavity. Optionally, in the above-described end bracket structure, a reinforcing cover plate is further provided on the column, and the reinforcing cover plate is provided with reinforcing holes that are adapted to the through hole.

[0022] Optionally, in the above-described end support structure, the end of the inclined tie member is cast into the second pile body for fixed connection with the second pile body.

[0024] The end support structure provided in this application connects at least two reinforcing members between two columns, with the two reinforcing members intersecting at a predetermined angle to form a triangular frame structure between the reinforcing members and the columns. Simultaneously, a mounting cavity for accommodating connecting components is provided on the columns, allowing the two ends of the main shaft to pass through perforations on opposite side walls of the mounting cavity and be locked by safety pins. Furthermore, the main cable passes sequentially through the main shaft and a limiting member to fix the main cable to the columns. A limiting notch is provided on the main shaft to mate with the limiting member, and the bottom wall of the limiting notch is flat, allowing the limiting member to abut against the bottom wall of the limiting notch. As can be seen from the above example, the end support structure provided in this application, through at least two reinforcing members intersecting at a predetermined angle between the two columns, connects the two columns, ensuring the stability of the columns and thus improving the wind resistance and stability of the entire end support. At the same time, by providing mounting cavities for accommodating connecting components on the columns, no additional parts are needed to adapt to the connecting components, reducing the number of parts, simplifying the installation process, ensuring assembly quality, and improving assembly efficiency. In addition, by abutting against the bottom wall of the limiting component and the limiting notch, the limiting component and the main shaft have a large contact area, ensuring the stability of the main cable connection.

Detailed Implementation

[0034] The core of this application is to provide an end bracket structure that improves the assembly efficiency of the end bracket while ensuring its stability.

[0035] Another core aspect of this application is to provide a flexible photovoltaic support system with the aforementioned end support structure.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] A cable-stayed photovoltaic (PV) support structure is a type of support frame for solar power plant modules. It mainly consists of end supports, a central support, and the supporting central cables and wind-resistant system. The end supports, as crucial components supporting the main cables, primarily constrain both ends of the main cables and provide the tensioning conditions for prestressing. The end supports typically consist of columns, compression piles, tie rods, and tension piles. The columns, through pin joints at their heads, convert the tension of the main cables into the diagonal tension of the tie rods, and the lower ends of the tie rods are connected to the tension piles.

[0038] In the existing technology, the end support usually has two columns, which are connected to the main cable through the column head pin node respectively. However, since the two columns are independent of each other, the wind resistance and stability of the entire end support are poor, and its adaptability to complex terrain is weak. At the same time, its unstable installation structure will also cause certain risks during the tensioning of the main cable.

[0039] In addition, the column head is usually fixed at the top of the column by welding or bolting. The column head is then connected to the connecting components of the main cable and the cable tie. This connection method usually requires processing such as cutting steel plates, bolting, and welding steel plates. The manufacturing process is relatively complex and involves a large number of parts, resulting in low assembly quality and efficiency, and high cost.

[0040] Therefore, as shown in Figure 1, this application discloses an end support structure, including columns 200 and connecting components 401. By having at least two reinforcing members 201 intersecting at a predetermined angle between the two columns 200, the two columns 200 are interconnected, ensuring the stability of the columns 200 and thus improving the wind resistance and stability of the entire end support. Simultaneously, by creating an installation cavity 202 on the column 200 to accommodate the connecting components 401, no additional parts are needed to fit the connecting components 401, reducing the number of parts, simplifying the installation process, ensuring assembly quality, and improving assembly efficiency. Furthermore, by having a limiting member 403 abut against the bottom wall of the limiting notch 4021, the limiting member 403 and the main shaft 402 have a large contact area, ensuring the stability of the main cable 500 connection.

[0041] The end bracket structure disclosed in the embodiments of this application will be explained and described in detail below with reference to Figures 1 to 6.

[0042] As shown in Figures 1 to 3, two columns 200 are installed on the first pile body 100. At least two reinforcing members 201 are connected between the two columns 200. The two reinforcing members 201 are intersecting at a preset angle so that the reinforcing members 201 and the columns 200 form a triangular frame structure. This allows the two columns 200 to be connected to each other, ensuring the stability of the columns 200 and improving the wind resistance and stability of the entire end support.

[0043] In some embodiments, as shown in Figures 1 and 2, the column 200 serves as the main supporting component of the end support structure. It is preferably made of square steel pipe with high strength steel to give the column 200 good load-bearing capacity and wind resistance. The bottom of the column 200 is equipped with a connecting part 205. The column 200 can be fixedly connected to the first pile body 100 through the connecting part 205. The connecting part 205 is usually made of steel plate or cast steel to ensure sufficient strength and durability. Compared with the column 200, the connecting part 205 is a small component, which allows for better structural design freedom. The connecting part 205 includes a reinforcing plate 2052 disposed opposite to both sides of the column 200 and a connecting base plate 2051 located on the bottom surface of the column 200. The two sides of the reinforcing plate 2052 can be bent to form a bending part, so that an installation space for installing the reinforcing plate 2052 is formed between the two bending parts. This makes it easy to fix the reinforcing plate 2052 to one side of the column 200 with fasteners such as bolts. At the same time, the connecting base plate 2051 can be fixed to the bottom surface of the column 200 by welding. The bending parts of the two opposite reinforcing plates 2052 form a clearance space for fixing the connecting base plate 2051 to the first pile body 100. This makes it easy to fix the connecting base plate 2051 to the first pile body 100 with fasteners such as bolts, thereby realizing the fixation of the column 200 and the first pile body 100. Of course, the reinforcing plate 2052 can also be fixed to one side of the column 200 by welding, or four reinforcing plates 2052 can be used and respectively set on the four sides of the column 200. This article does not limit this. It should be noted that the column 200 can also be made of round steel pipe or other metal pipes depending on the actual situation. This article does not limit this.

[0044] In the above embodiments, as shown in Figures 1 and 2, the first pile 100 serves as a support base, which may be a precast concrete pile, a steel pile, or other types of piles, and the first pile 100 is typically partially buried underground to provide stable support.

[0045] In some embodiments, as shown in Figures 1 and 2, there are two reinforcing members 201, and the two reinforcing members 201 intersect at the same intersection point of the column 200 at a predetermined angle, so that the reinforcing members 201 and the column 200 form an integral triangular frame structure. The predetermined angle can be 30°, 45°, 60°, etc. For ease of assembly, the reinforcing members 201 and the column 200 can be movably connected, and a locking mechanism is provided between the reinforcing members 201 and the column 200 to lock the connection between them.

[0046] In some embodiments, as shown in Figures 1 and 2, a connecting sleeve 203 is provided at the end of the reinforcing member 201. The connecting sleeve 203 forms a space to accommodate the column 200, and the connecting sleeve 203 slides in conjunction with the column 200. Meanwhile, the locking mechanism includes a first mounting hole on the column 200 and a second mounting hole on the connecting sleeve 203. The second mounting hole is adapted to the first mounting hole so that the column 200 and the connecting sleeve 203 can be connected and fixed by bolts or other fasteners. To ensure the reliability of the connection between the connecting sleeve 203 and the column 200, multiple second mounting holes are distributed on both opposite sides of the connecting sleeve 203. Simultaneously, multiple first mounting holes adapted to the second mounting holes are provided at positions corresponding to the second mounting holes on the column 200. This allows the column 200 and the connecting sleeve 203 to be connected and fixed by multiple bolts or other fasteners, thereby improving the connection strength between the connecting sleeve 203 and the column 200 and ensuring the reliability of the connection between them. In addition, to facilitate the assembly of the reinforcing member 201, the number of first mounting holes on the column 200 in the height direction can be greater than the number of second mounting holes on the connecting sleeve 203, so that when the reinforcing member 201 is installed, the installation position of the end of the reinforcing member 201 can be adjusted, which facilitates the assembly of the reinforcing member 201.

[0047] In some embodiments, the locking mechanism may also employ a spring protrusion within the first mounting hole. When the reinforcing member 201 is assembled with the column 200, simply move the connecting sleeve 203 on the column 200. When the connecting sleeve 203 contacts the spring protrusion, continue moving the connecting sleeve 203. At this time, the spring protrusion is compressed into the first mounting hole until the second mounting hole on the connecting sleeve 203 aligns with the first mounting hole. Then, the spring protrusion returns to its natural state under the action of elasticity, and simultaneously engages with the second mounting hole on the connecting sleeve 203. When it is necessary to adjust the end position of the reinforcing member 201, simply press the spring protrusion into the first mounting hole while moving the connecting sleeve 203, so that the spring protrusion engages with the second mounting hole at the target position. It should be noted that in the above embodiments, the number of first mounting holes on the column 200 corresponding to the second mounting holes can be one, and a spring protrusion is provided in the first mounting hole. Meanwhile, the number of second mounting holes on the connecting sleeve 203 can be two, three, four, or more, and each second mounting hole can be arranged vertically along the connecting sleeve 203, i.e., along the height direction of the column 200, so that the connecting sleeve 203 can be moved along the height direction of the column 200 to adjust the mounting position of the end of the reinforcing member 201. Alternatively, the number of first mounting holes on the column 200 corresponding to the second mounting holes can also be two, three, four, or more, and spring protrusions can be provided in some or all of the first mounting holes. Simultaneously, the second mounting holes of the connecting sleeve 203 are corresponding to the first mounting holes, and the number of second mounting holes distributed vertically along the connecting sleeve 203 can be greater than the number of first mounting holes, so that the connecting sleeve 203 can be moved and adjusted along the height direction of the column 200.

[0048] In some embodiments, as shown in Figures 1 and 2, the connecting sleeve 203 may adopt a U-shaped structure and have an opening 2031 for connecting the connecting sleeve 203 to the column 200. Simultaneously, the reinforcing member 201 is hinged to the side of the connecting sleeve 203 opposite to the opening 2031. Specifically, a support plate 2012 is vertically arranged on the side of the connecting sleeve 203 opposite to the opening 2031, and the support plate 2012 can be fixed to the connecting sleeve 203 by welding. Meanwhile, an ear plate 2011 can be fixed to the end of the reinforcing member 201, and the ear plate 2011 is hinged to the support plate 2012. This allows for relative displacement between the reinforcing member 201 and the column 200, absorbing and dispersing loads under earthquakes, wind, and other loads, thereby improving the safety of the end support structure and reducing stress concentration in the end support structure, which is beneficial for improving the stability and toughness of the end support structure. It should be noted that, in order to ensure the overall stability of the connecting sleeve 203 and the support plate 2012, multiple reinforcing ribs can be welded between the support plate 2012 and the connecting sleeve 203 to improve the connection strength between the connecting sleeve 203 and the support plate 2012, thereby ensuring the overall stability of the connecting sleeve 203 and the support plate 2012.

[0049] In the above embodiments, the number of reinforcing members 201 can be, but is not limited to, two, three, four or more. Each reinforcing member 201 can be connected end-to-end, with adjacent reinforcing members 201 arranged at a predetermined angle. Alternatively, the reinforcing members 201 can be arranged in pairs, forming an intersection point in the middle, thus creating a scissor frame structure. The specific structural form and number of reinforcing members 201 can be determined according to actual conditions, and are not limited herein.

[0050] It should be noted that in the above embodiments, the reinforcing member 201 can be made of hollow steel pipe, I-beam, channel steel, etc., and this article does not limit it.

[0051] As shown in Figures 3 to 6, the column 200 is provided with a mounting cavity 202 to accommodate the connecting assembly 401, and the connecting assembly 401 includes a main shaft 402 and a limiting member 403. A through hole is provided at the center of the main shaft 402 to allow the main cable 500 to pass through. Simultaneously, through holes for the main shaft 402 are provided on two opposite side walls of the mounting cavity 202, and a strip-shaped hole 2021 for the main cable 500 to pass through is provided on the side wall of the mounting cavity 202 perpendicular to the surface of the through holes. During assembly, both ends of the main shaft 402 are passed through the through holes and locked by safety pins 4022 to prevent the main shaft 402 from dislodging from the through holes, thereby fixing the main cable 500 to the column 200. Meanwhile, a limiting member 403 is sleeved at the end of the main cable 500. By passing the main cable 500 through the limiting member 403, the main cable 500 is prevented from coming out of the through hole of the main shaft 402, thereby ensuring the reliability of the main cable 500 connection. As can be seen from the above embodiment, by providing an installation cavity 202 on the column 200 to accommodate the connecting component 401, there is no need to add additional parts to adapt to the connecting component 401, reducing the number of parts, simplifying the installation process, ensuring assembly quality, improving assembly efficiency, and reducing costs. It should be noted that the strip hole 2021 can be a strip-shaped round hole, a rectangular hole, etc., or a round hole or a square hole for the main cable 500 to pass through can be provided on the side wall of the installation cavity 202 perpendicular to the surface where the through hole is located, as long as the main cable 500 and the limiting member 403 can move within a certain angle range, this article does not limit it.

[0052] In the above embodiments, the opening on the column 200 can be made by, but is not limited to, laser cutting, or by steel structure hot cutting, flame cutting, cold cutting or water cutting, etc., which are not limited here.

[0053] In some embodiments, as shown in Figures 5 and 6, a limiting notch 4021 is provided on the main shaft 402 to cooperate with the limiting member 403. The through hole of the main shaft 402 is located on the bottom wall of the limiting notch 4021, so that the main cable 500 passes through the through hole of the limiting notch 4021 and the limiting member 403 in sequence, and abuts against the bottom wall of the limiting notch 4021 through the limiting member 403 to lock the main cable 500 and prevent the main cable 500 from coming out of the through hole on the main shaft 402. The bottom wall of the limiting notch 4021 is flat, thereby ensuring that the limiting member 403 and the bottom wall of the limiting notch 4021 have a large contact area, avoiding stress concentration and keeping the main cable 500 in a stable locked state.

[0054] In some embodiments, as shown in Figures 4 to 6, the limiting member 403 may include an end 4031, and the end 4031 may be designed in a stepped manner so that the small-diameter end of the end 4031 can extend into the mounting cavity 202 through the strip hole 2021 and abut against the bottom wall of the limiting notch 4021, while the large-diameter end of the end 4031 is exposed on the outside of the mounting cavity 202, so as to facilitate the connection and fixation between the end 4031 and the main cable 500 by threaded engagement.

[0055] As shown in Figure 3, the end support structure includes a tie rod 400, which has two oppositely arranged ends. For ease of understanding, the two ends of the tie rod 400 are defined as the first end and the second end, respectively. The first end of the tie rod 400 is connected to the second pile 300, and the second end of the tie rod 400 is rotatably connected to the main shaft 402 via a tie sleeve 404 to form a cable-stayed structure. This cable-stayed structure design allows the load to be transferred to the column 200, enabling the flexible photovoltaic support system to have a large span capacity and thus adapt to various terrains and complex geological conditions. Specifically, one end of the tie sleeve 404 is rotatably connected to the main shaft 402, and the other end of the tie sleeve 404 tightens the tie rod 400 to provide the required tension. The tie rod 400 is rotatably connected to the main shaft 402, which helps to absorb and disperse loads caused by wind loads, earthquakes, etc., thereby improving the wind resistance and seismic resistance of the end support structure.

[0056] In the above embodiments, the inclined tie member 400 may be a component that can provide a certain preload, such as a tie cable, a wire rope, an inclined tie steel pipe, or an inclined tie steel bar. This article does not limit the type of component.

[0057] In some embodiments, as shown in Figure 3, the second pile 300 has the same structure and properties as the first pile 100, with a portion of it also embedded underground. The first end of the diagonal brace 400 can be cast into the second pile 300 for fixed connection, while the second end of the diagonal brace 400 is rotatably connected to the main shaft 402 via a diagonal brace sleeve 404. Furthermore, to ensure the overall stability of the pile foundation, the first pile 100 and the second pile 300 can be connected by a reinforcing beam 301. This reinforcing beam can be made of reinforced concrete, steel, or other materials to connect the first pile 100 and the second pile 300, thus ensuring the overall stability of the pile foundation. Alternatively, the first piles 100 at the bottom of the two columns 200 can be connected by a reinforcing beam 301, and the two second piles 300 can also be connected by a reinforcing beam 301 to improve the overall stability and bearing capacity of the pile foundation, reduce uneven settlement, and thus ensure the overall stability of the end support structure.

[0058] In some embodiments, as shown in FIG4, the diagonal tie sleeve 404 may include a connecting plate 4041 and two hinge bolts 4042. The connecting plate 4041 serves as the central force-bearing component of the diagonal tie sleeve 404, and can be used to transmit the force of the diagonal tie member 400 to the connecting assembly 401. The connecting plate 4041 may be made of metal to provide sufficient strength and rigidity, while the two hinge bolts 4042 are symmetrically arranged on the connecting plate 4041 for fixing the diagonal tie sleeve 404 to the spindle 402. The open ends 4043 of the two hinge bolts 4042 are symmetrically fitted onto both ends of the spindle 402. The design structure of the hinge bolts 4042 allows for a certain degree of adjustment of the distance and tension of the diagonal tie member 400 in the length direction. As can be seen from the above embodiments, the tension force of the diagonal tie member 400 is transmitted to the main shaft 402 through the diagonal tie sleeve 404 and then acts on the main cable 500. The diagonal tie member 400 is directly connected to the connecting plate 4041, while the two hinge bolts 4042 transmit the tension force to the symmetrical ends of the main shaft 402. This structure applies a more uniform tension to the main cable 500, making the main cable 500 more stable.

[0059] In some embodiments, as shown in Figures 3 and 4, a reinforcing cover plate 204 is also provided on the top of the column 200, and a reinforcing hole is provided on the reinforcing cover plate 204 at a position corresponding to the through hole of the mounting cavity 202, so that the spindle 402 can pass through the reinforcing hole and be locked by the safety pin 4022. The width of the reinforcing cover plate 204 can be determined according to the width of the column 200. The reinforcing cover plate 204 can be fixed to the column 200 by welding to strengthen the column 200 after the hole is opened, improve the overall stability of the top of the column 200, and prevent the column 200 from becoming unstable after the hole is opened. At the same time, the reinforcing cover plate 204 reinforces the opening on the side of the column 200, increases the contact area between the spindle 402 and the through hole on the side of the column 200, and prevents the steel plate on the side of the column 200 from yielding and deforming under stress.

[0060] This application also discloses a flexible photovoltaic support system, including a main cable 500 and an end support structure, and an end support structure is provided at at least one end of the main cable 500. The end support structure is the end support structure disclosed in the above embodiment.
