Description

Technical Field

[0001] This utility model relates to the field of photovoltaic flexible support technology, and in particular to a high-load-bearing micro-motion wear photovoltaic flexible support. Background Technology

[0002] Currently, flexible photovoltaic supports come in two-cable and three-cable structures. Two-cable structures can only be used in areas with small spans and low loads, while three-cable structures are suitable for areas with large spans and high loads. However, traditional three-cable structures only have inclined stay cables set in the direction outside the axis corresponding to the component cables, which places extremely high demands on the end columns and end piles. The cross-sectional dimensions of the end columns and end piles are very large, which is not conducive to production, transportation, and construction. This has resulted in persistently high costs for flexible photovoltaic supports and frequent collapse accidents. Regardless of whether it is a two-cable or three-cable structure, both are made of black iron that has been processed and then hot-dip galvanized, resulting in high production costs, low production efficiency, and the inability to standardize or modularize production, as well as significant difficulties in dimensional adjustment.

[0003] Traditional flexible support structures suffer severe wear at the anchoring nodes of the end columns and at the crossbeams of the middle columns, significantly impacting their strength and jeopardizing the safety and reliability of the entire row of flexible supports. Furthermore, the load-bearing cables of traditional flexible supports are one to two sizes larger than the component cables. In high-load areas and large-span applications, the required specifications for the load-bearing cables exceed the maximum specifications of steel strands currently available on the market, necessitating customized production, which results in low production efficiency. Moreover, the variety of steel strand specifications and the need for numerous matching anchors increase the difficulty of construction and installation, requiring more tensioning equipment, and incurring significant time, labor, and material costs. Additionally, the anchors of traditional flexible supports have weak corrosion resistance, making them prone to fatigue breakage and stripping.

[0004] Therefore, those skilled in the art have provided a high-load-bearing, micro-motion wear photovoltaic flexible support to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-load-bearing, micro-abrasion-resistant photovoltaic flexible support. This is achieved by adding inclined stay cables to the load-bearing cables and diagonal braces under the end beams to enhance load-bearing capacity. The use of zinc-aluminum-magnesium cold-formed thin-walled steel reduces costs and improves production efficiency. Wear-resistant structures are installed at the end columns and middle beams to ensure the safety and reliability of the support. Optimizing the steel strand specifications in high-load areas saves costs and simplifies construction, reducing the probability of anchoring errors and the need for different types of tensioning equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-load-bearing, micro-abrasion-resistant photovoltaic flexible support includes a central support, module cables, load-bearing cables, and end supports. The end supports include multiple end piles, end beams, a first steel column, a second steel column, a first diagonal brace, a second diagonal brace, a first stay cable, a second stay cable, a third stay cable, multiple anchor piles, and multiple first anchors. A first steel column is located at the center of the upper surface of one end pile on one front side, and a second steel column is located at the center of the upper surface of the other end pile on the other front side. A first diagonal brace is hinged to the other side of the lower end of the first steel column, and a second diagonal brace is hinged to one side of the lower end of the second steel column. The upper ends of the first and second diagonal braces... All are hinged to the middle of the lower surface of the end beam. The two sides of the outer wall of the end beam are respectively hinged to the outer walls of the upper sides of the first steel column and the second steel column. A fixing plate is fixedly connected to the middle of the upper surface of the end beam. The front end and rear end of the fixing plate are provided with first anchors. The rear end of the upper part of the first steel column and the second steel column are fixedly connected with first anchors. Multiple first anchors are provided in the middle of the upper surface of the rear end pile. U-bolts are fixedly connected to the outer wall of the rear end of the first anchor. The first anchor, the fixing plate, the first steel column, the second steel column and the end pile are all fixedly connected by U-bolts and fixing nuts.

[0008] The above technical solutions allow for the use of zinc-aluminum-magnesium cold-formed thin-walled steel to replace hot-dip galvanized steel for various steel columns, inclined beams, and braces. In particular, the use of zinc-aluminum-magnesium cold-formed thin-walled steel composite sections reduces production costs and increases production efficiency. It also facilitates bolt connections, improves construction efficiency, and reduces construction costs.

[0009] Furthermore, each end beam is provided with two component cables at its front end, and a load-bearing cable is provided at the middle of the front end of the first anchor. A first diagonal brace and a second diagonal brace are provided under the end beam to which the load-bearing cable is anchored. A tie rod is provided between the first diagonal brace and the second diagonal brace. The tie rod includes an angle iron. The angle iron, the first bolt, and the second bolt connect the first diagonal brace, the second diagonal brace, and the tie rod.

[0010] Through the above technical solutions, by also setting corresponding stay cables for the load-bearing cables under the component cables, and setting diagonal braces under the end beams where the load-bearing cables are anchored, the load-bearing capacity of the flexible support is improved. Furthermore, tie rods can be set between the diagonal braces, and the diagonal braces and tie rods can be connected by angle irons and bolts to enhance the stability of the diagonal, reduce the cross-sectional area of ​​the diagonal braces, and save costs. Moreover, zinc-aluminum-magnesium cold-formed thin-walled steel can be used instead of hot-dip galvanized materials for various steel columns, diagonal beams, diagonal braces, and other components, thereby reducing production costs and improving production efficiency. Through the above technical design, while improving the load-bearing capacity of the end support, the requirements for steel columns are reduced, the cross-sectional size can be reduced, the weight is reduced, and it is easier to install manually, resulting in a significant reduction in material and construction costs.

[0011] Furthermore, the first and second steel columns are provided with wear-resistant steel strand anchoring nodes at their upper ends. Each steel strand anchoring node includes a column cap, which includes an end cap plate connected to a first stiffening plate. A first pad is provided at the upper end of the column cap, and the first pad is fixed to the first stiffening plate. The upper surfaces of the first pad and the first stiffening plate are flush, and the vertical height of the first pad is less than or equal to that of the first stiffening plate. Each steel strand anchoring node has a component cable at its front end, and the component cable has vertical space for vertical routing along the stiffening plate. The first pad has a through hole on its outer wall and a groove on its outer wall. A second anchor is placed inside each groove. The outer wall of the column cap is fixedly connected to a first ear plate and a second ear plate. The first ear plate and the first pad are centered and perpendicular. The first ear plate is hinged to the first anchor at the end of the first and second stay cables through a hole. The U-bolt in the first anchor passes through the hole. The second ear plate is fixedly connected to the column cap. The second ear plate is perpendicular to the first stiffening plate. The center line of the second ear plate coincides with the center line of the column cap.

[0012] Through the above technical solution, wear-resistant steel strand anchoring nodes are set at the upper end of the end column, thereby avoiding wear of the component cable at this point and ensuring the safety and reliability of the flexible support. The column cap has an end sealing plate, which is connected to the stiffening plate. The anchor plate and stiffening plate are fixed at a vertical height less than or equal to the stiffening plate. The component cable has vertical space for vertical routing in the stiffening plate to avoid wear caused by contact between the steel strand and the steel component at this position. The anchor plate has through holes to facilitate the passage of the component cable. The anchor plate is provided with grooves for precise placement of the first anchor. The first ear plate is fixed to the column cap. The first ear plate and the pad are centered and vertical. The first ear plate is hinged to the first anchor at the end of the stay cable through a hole. The U-bolt in the first anchor passes through the hole. The second ear plate is fixed to the column cap. The second ear plate is perpendicular to the stiffening plate, and the center line of the second ear plate coincides with the center line of the column cap.

[0013] Furthermore, both the component cable and the load-bearing cable are equipped with a steel strand fretting wear axial sliding device on the support. The steel strand fretting wear axial sliding device includes a second pad, and a middle crossbeam is fixedly connected to the middle of the lower surface of the second pad. The middle crossbeam is fixed to the second pad by bolts or welding. A horn tube is provided at the upper end of the second pad, and the horn tube is fixedly connected to the second pad. Both ends of the horn tube are horn mouths. An inner liner tube is provided inside the horn tube. The inner wall of the inner liner tube is sprayed with a polyurea coating. The steel strand fretting wear axial sliding device includes a component cable or a load-bearing cable. The outer layer of the second steel strand of the component cable or load-bearing cable is coated with a polyurea coating. The component cable or load-bearing cable passes through the inner liner tube. A second stiffening plate is tightly attached to the middle of the upper end of the horn tube. The second stiffening plate is fixedly connected to the upper surface of the second pad.

[0014] Through the above technical solution, in high-load areas, the load-bearing cable and component cable can be optimized to be steel strands of the same specification, and the steel strands are smaller in size. This saves on steel strand costs, simplifies construction, and only requires tensioning and anchoring of one specification of steel strand, avoiding errors in anchoring multiple specifications of steel strands. It also reduces the need for tensioning equipment models, requiring only one model.

[0015] Furthermore, the second anchor includes an anchor cup, which clamps the first steel strand with a clamping plate. The second anchor includes a pressure plate and a fatigue-resistant ring. The lower surface of the pressure plate is fixedly connected to the upper surface of the fatigue-resistant ring. A protective tube is fixedly connected to the lower end of the anchor cup.

[0016] Through the above technical solution, the first anchor has high corrosion resistance and fatigue resistance. The anchor cup holds the steel strand with clamps. The protective cover protects the steel strand, clamps, and anchor cup in a relatively sealed environment, protecting the anchor section steel strand and clamps from wind and rain erosion. The fatigue-resistant ring is made of wear-resistant high-strength plastic to prevent the steel strand from coming into contact with steel at the bottom hole of the anchor cup, thereby preventing fatigue fracture of the steel strand at this point. The pressure plate presses down on the fatigue-resistant ring, and the protective tube protects the PE stripped section of the steel strand and is fixed to the bottom of the anchor cup.
