Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic engineering, in particular to a combined structure of a concrete bent frame and a skeleton-type flexible suspension cable. Background Art

[0002] The span of traditional flexible photovoltaic brackets ranges from 15 to 50 meters. Flexible photovoltaic brackets can be used in scenes such as mountains and hills, fish ponds, and sewage treatment plants. The current flexible photovoltaic brackets are not high. If steel structures are used as flexible photovoltaic brackets, the cost is high and it is difficult to meet the economic requirements. In recent years, many high-energy-consuming enterprises need to carry out green power transformation to meet the relevant national policy requirements. Against this background, many companies have gradually started to build distributed photovoltaics, but there are many technical pain points in the process of promoting distributed photovoltaics. For example, the production workshops of high-energy-consuming companies were built relatively early, and most workshops have suffered varying degrees of structural damage, making it difficult to install photovoltaic panels on them. If photovoltaic panels need to be installed on them, the structure needs to be inspected and identified. For workshops without original drawings, their structures are difficult to restore and structural reinforcement cannot be carried out. Considering the high cost and risk factor of the inspection, identification, reinforcement and transformation of existing buildings, it is of great significance to invent a flexible bracket that can span existing buildings, without interfering with existing buildings, and reducing damage to existing structures.

[0003] Publication No. CN220492889U discloses a fish-belly flexible photovoltaic system, comprising a main cable, a load-bearing cable, and a stabilizing cable. One end of each of the main, load-bearing, and stabilizing cables is secured to a first compression pile; the other ends of each of the main, load-bearing, and stabilizing cables are secured to a second compression pile. The main, load-bearing, and stabilizing cables are arranged in a fish-belly pattern between the first and second compression piles. The fish-belly flexible photovoltaic system provided herein has excellent wind resistance and stability.

[0004] Announcement No. CN219436900U discloses a fish-belly four-cable photovoltaic flexible bracket, including a terminal bracket mechanism and an intermediate bracket mechanism, wherein a first component cable and a second component cable are installed on the top of the terminal bracket mechanism and the intermediate bracket mechanism, and triangular wind-resistant mechanisms are arranged at equal intervals on the first component cable and the second component cable, and a group of photovoltaic panels are installed between two adjacent triangular wind-resistant mechanisms relative to the first component cable and the second component cable; the triangular support frame can be installed and assembled with anti-tension cables and anti-compression cables respectively, so under the action of anti-tension cables and anti-compression cables, the wind suction and wind pressure resistance are effectively enhanced, and the stability is increased. There are at most two U-shaped rope buckles installed on the connecting arm and the bottom of the triangular support frame, and the positions of the U-shaped rope buckles installed on each connecting arm and the bottom of the triangular support frame are different, so the anti-tension cables and anti-compression cables are arranged in a fish-belly style, and the overall structure is more stable.

[0005] The above patents use a fish-belly flexible photovoltaic bracket. The fish-belly structure will affect the lower clearance. The column material uses a steel structure with relatively soft rigidity and high cost. Concrete racks are needed to increase the rigidity of the structure and improve the stress. The cost of concrete is low, and concrete can be prefabricated in the factory to reduce the on-site construction period. Summary of the Invention

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0028] Example 1. A concrete bent frame and skeleton-type flexible suspension cable combined structure, the structure is as follows Figure 1 The structure comprises a skeleton unit, which includes several bents 1 arranged in a row. A set of load-bearing cables 2 arranged at equal heights are connected between the bents 1. Below the load-bearing cables 2 is a set of wind-resistant cables 3, the same number as the load-bearing cables 2. The load-bearing cables 2 and the wind-resistant cables 3 are connected by a number of connecting cables 4. The load-bearing cables 2 are arranged in a catenary shape, and the wind-resistant cables 3 are arranged in a mirror-symmetrical manner with the load-bearing cables 2. The connecting cables 4 are gradually shortened from the bents 1 to the mid-span position. Above the load-bearing cables 2 is a set of leveling cables 5, the same number as the load-bearing cables 2. The leveling cables 5 and the load-bearing cables 2 are connected by a number of rigid struts 6. By arranging the anti-wind cable 3 and the load-bearing cable 2 in a mirror-symmetrical manner, spatial force is formed, thereby increasing the wind-resistant bearing capacity; by arranging the load-bearing cable 2, the anti-wind cable 3 and the leveling cable 5 to cooperate with the rigid strut 6 to form a U-shaped structure, the structural stiffness and deflection of the present application are increased; by arranging the connecting cable 4 and the rigid strut 6, the entire structure forms an over-static structure, thereby further improving the structural stiffness and deflection of the present application.

[0029] The load-bearing cables 2 and the wind-resistant cables 3 are gradually brought together from the rack 1 to the mid-span position. The wind-resistant cables 3 and the load-bearing cables 2 are connected one-to-one by a number of connecting cables 4. The leveling cables 5 are connected by a number of horizontal struts 7. The load-bearing cables 2 are connected by a number of connecting cables 4. The wind-resistant cables 3 are connected by a number of connecting cables 4. By gradually bringing the load-bearing cables 2 and the wind-resistant cables 3 together from the rack 1 to the mid-span position to form a skeleton structure, the structural rigidity is increased, while the wind load area is reduced and the impact of the wind load is reduced. By arranging horizontal struts 7 between each leveling cable 5, connecting cables 4 between each load-bearing cable 2, and connecting cables 4 between each wind-resistant cable 3, the static determinate grade of the entire structure is further improved and the structural rigidity is improved.

[0030] The bent frame 1 comprises two side-by-side concrete columns 8 connected by a concrete beam 9. The use of concrete columns 8 and concrete beams 9 to form the bent frame 1 reduces the overall structural cost compared to using a steel bent frame 1. By utilizing the mass production characteristics of prefabricated components, construction progress can be accelerated and construction costs can be reduced.

[0031] An end cable 10 is provided at the top of the bent frame 1 and on a side away from the load-bearing cable 2, and an end of the end cable 10 away from the bent frame 1 is anchored in the foundation. The provision of the end cable 10 improves the stability of the bent frame 1.

[0032] Example 2. During use, the photovoltaic panels can only be arranged on one frame unit. In order to improve the utilization of space, an improvement is made on the basis of Example 1. The structure is referenced to Figure 3 The several skeleton units are arranged in parallel, and the several skeleton units are connected by stabilizing cables 11, and the stabilizing cables 11 are connected to the mid-span position of the load-bearing cables 2; purlins are laid on the several skeleton units parallel to the direction of the stabilizing cables 11 to form a roof truss system, and then photovoltaic panels are laid on the purlins.

[0033] Obviously, the above is only a partial embodiment of the present invention, not all embodiments. The above embodiments are not intended to limit the present invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any combination, modification, equivalent replacement, improvement, and other embodiments that can be made by those of ordinary skill in the art within the spirit and principles of the present invention shall be within the scope of protection of the present invention.
