Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to an end support structure and a flexible photovoltaic support system. Background Technology

[0002] 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.

[0003] 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.

[0004] Therefore, how to improve the stability of the end support has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0040] The core of this application is to provide an end support structure to improve the stability of the end support.

[0041] Another core aspect of this application is to provide a flexible photovoltaic support system with the aforementioned end support structure.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Therefore, such as Figure 1 As shown in the illustration, this application discloses an end support structure, including a first pile body 100, a column 200, a second pile body 300, and a tie rod 400. 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 component 401, no additional parts are needed to adapt to the connecting component 401, reducing the number of parts, simplifying the installation process, and improving assembly efficiency. Furthermore, by fixing the tie rod 400 to the main cable 500 to form a cable-stayed structure, the load can be transferred to the column 200, giving the flexible photovoltaic support system a large span capacity, thus adapting to various terrains and complex geological conditions.

[0046] The following will combine Figures 1 to 6 The end support structure disclosed in the embodiments of this application will be explained and described in detail.

[0047] Among them, such as Figures 1 to 3As shown, the column 200 is installed on the first pile body 100, and there are two columns 200. 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 column 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 thus improving the wind resistance and stability of the entire end support.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the column 200, as the main supporting component of the end support structure, is preferably made of square steel pipe with high strength steel so that the column 200 has good load-bearing capacity and wind resistance. The bottom of the column 200 is equipped with a connecting part 205, through which the column 200 can be fixedly connected to the first pile body 100. It 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, and its structural design has a greater degree of 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 metal pipe, etc., depending on the actual situation. This article does not limit this.

[0049] In the above embodiments, such as Figure 1 and Figure 2 As shown, the first pile 100 serves as a support base, which can be a precast concrete pile, a steel pile, or other types of piles, and the first pile 100 is usually partially buried underground to provide stable support.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, 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 a 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.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, 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 fit 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 distributed along the height direction on the column 200 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.

[0052] 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 within the column 200. When the connecting sleeve 203 contacts the spring protrusion, continue moving the connecting sleeve 203. At this point, 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 simultaneously moving the connecting sleeve 203, causing the spring protrusion to engage 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, 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.

[0053] In some embodiments, such as Figure 1 and Figure 2As shown, the connecting sleeve 203 can adopt a U-shaped structure, and the connecting sleeve 203 has an opening 2031 to connect the connecting sleeve 203 to the column 200. At the same time, 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. At the same time, an ear plate 2011 can be fixed to the end of the reinforcing member 201. The ear plate 2011 is hinged to the support plate 2012, so that there is a relative displacement between the reinforcing member 201 and the column 200, so as to absorb and disperse the load under the action of earthquake, wind and other loads, thereby improving the safety of the end support structure, reducing the stress concentration of the end support structure, and 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.

[0054] 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.

[0055] 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.

[0056] like Figure 3 As shown, the cable tie 400 has two opposite ends, which are defined as the first end and the second end for ease of understanding. The first end of the cable tie 400 is connected to the second pile 300, and the second end is fixedly connected to the main cable 500 via a connecting assembly 401 to form a cable-stayed structure. A mounting cavity 202 for accommodating the connecting assembly 401 is provided on the column 200, eliminating the need for additional parts to fit the connecting assembly 401, reducing the number of parts, simplifying the installation process, and improving assembly efficiency. Furthermore, by fixing the cable tie 400 to the main cable 500 to form a cable-stayed structure, the load can be transferred to the column 200, giving the flexible photovoltaic support system a large span capacity, thus adapting to various terrains and complex geological conditions.

[0057] 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.

[0058] In some embodiments, such as Figure 3 As shown, 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 tie rod 400 can be cast into the second pile 300 for fixed connection, while the second end of the tie rod 400 is fixed to the main cable 500 via a connecting assembly 401 to tighten the main cable 500. 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.

[0059] In some embodiments, such as Figure 4As shown, the connecting assembly 401 includes a main shaft 402, a limiting member 403, and a diagonal sleeve 404. A through hole is provided at the center of the main shaft 402 to allow the main cable 500 to pass through. A through hole for the main shaft 402 is provided on the opposite side wall 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 through hole. During assembly, both ends of the main shaft 402 are passed through the through holes and locked with safety pins 4022 to prevent the main shaft 402 from coming out of the through holes, thereby fixing the main cable 500 to the column 200. Simultaneously, a limiting member 403 is provided 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 main shaft 402, thus ensuring the reliability of the main cable 500 connection. Furthermore, the diagonal bracing member 400 can be rotatably connected to the main shaft 402 via the diagonal bracing sleeve 404. Specifically, one end of the diagonal bracing sleeve 404 is rotatably connected to the main shaft 402, and the other end of the diagonal bracing sleeve 404 tightens the diagonal bracing member 400 to provide the required tension. The diagonal bracing member 400 can be rotatably connected to the main shaft 402, which is beneficial for absorbing and dispersing loads caused by wind loads, earthquakes, etc., thereby improving the wind resistance and seismic resistance of the end support structure. 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 can be provided on the side wall of the mounting cavity 202 perpendicular to the surface where the through hole is located for the main cable 500 to pass through, as long as the main cable 500 and the limiting member 403 can move within a certain angle range. This article does not impose any restrictions on this.

[0060] 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.

[0061] In some embodiments, such as Figures 4 to 6 As shown, the limiting member 403 includes an end 4031, and simultaneously as Figure 5 and Figure 6As shown, a limiting notch 4021 is provided on the main shaft 402 to mate with the end 4031. 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 end 4031 in sequence, and abuts against the bottom wall of the limiting notch 4021 through the end 4031 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, which ensures that the end 4031 and the bottom wall of the limiting notch 4021 have a large contact area, avoids stress concentration, and keeps the main cable 500 in a stable locked state. The end 4031 can adopt a stepped design 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 outside the mounting cavity 202 so that the end 4031 and the main cable 500 can be connected and fixed by threaded engagement.

[0062] In some embodiments, such as Figure 4 As shown, 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 main shaft 402. The open ends 4043 of the two hinge bolts 4042 are symmetrically fitted onto both sides of the main shaft 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 inclined tie member 400 is transmitted to the main shaft 402 through the inclined tie sleeve 404 and then acts on the main cable 500. The inclined tie member 400 is directly connected to the connecting plate 4041, while the two hinge bolts 4042 transmit the tension force to the symmetrical positions on both sides of the main shaft 402. This structure applies a more uniform tension to the main cable 500, making the main cable 500 more stable.

[0063] In some embodiments, such as Figure 3 and Figure 4As shown, 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 the 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.

Therefore, the end support structure has all the technical effects of the above end support structure, which will not be elaborated here.
