[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0024] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted.

[0025] In recent years, the global carbon neutrality goal has been clear, and photovoltaics is expected to lead the rapid development of renewable energy. Moreover, with the explosive growth of the photovoltaic industry, flexible photovoltaic brackets have also shown great advantages in the construction of power stations in complex terrain.
[0026] Flexible photovoltaic bracket is a large-span photovoltaic module support structure designed based on the tension structure system. It adopts the method of prestressing steel wire rope or steel strand between the fixed points at both ends, and provides support reaction force through rigid structure and outer inclined steel strand, so as to achieve the characteristics of large span, high clearance and long column distance. Compared with traditional rigid brackets, flexible photovoltaic brackets have significant structural advantages; however, during the use of flexible photovoltaic brackets, affected by environmental factors, some parts need to be replaced and maintained regularly to ensure the reliability and firmness of the bracket. However, when replacing parts, existing flexible photovoltaic brackets need to use large equipment or support devices, and stabilize the bracket through multi-person collaboration. To replace the corresponding parts, the whole process not only has a large investment cost, but also has high safety risks and slow replacement efficiency.
[0027] In order to solve the above technical defects, the inventor provides a photovoltaic flexible bracket oblique structure and method.
[0028] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-Figure 6As shown, in an embodiment of the present invention, a first aspect provides a photovoltaic flexible bracket inclined structure, the inclined structure comprising an end support 1 and an anchor plate 9, the end support 1 and the anchor plate 9 are arranged relative to each other, the end support 1 is connected to the photovoltaic flexible bracket (not shown in the figure), and the photovoltaic flexible bracket is supported; a hooking device comprises a first hooking assembly and a second hooking assembly, one end of the first hooking assembly and the second hooking assembly are connected to the end support 1, and the other end is connected to the anchor plate 9, and the first hooking assembly is located above the second hooking assembly, and the end support 1 is connected to the anchor plate 9 by using the first hooking assembly and the second hooking assembly, so as to form a stable triangular inclined structure with high stability. When checking and replacing parts in the first hook assembly or the second hook assembly, the hook assembly that has not undergone parts replacement can still keep the end support 1 stable and support the photovoltaic flexible frame; at the same time, due to the effect of the hook assembly that has not undergone parts replacement, there is no need to use large equipment or support devices, and the bracket can be stabilized and the corresponding parts can be replaced through the collaboration of multiple people, thus reducing the cost and labor input; the limiting device is arranged on the top of the anchor plate 9, and is used to limit the first hook assembly and the second hook assembly, forming a double limiting mechanism, which not only improves the overall stability of the structure, but also effectively prevents structural instability caused by the failure of a single limiting point. Figure 1 As shown, the limiting device includes a first limiting component and a second limiting component. One end of the first hook component is connected to the end support 1, and the other end is connected to the anchor plate 9 through the first limiting component; one end of the second hook component is also connected to the end support 1, and the other end is connected to the anchor plate 9 through the second limiting component. In this structural composition, the first limiting component and the second limiting component provide double support points for the end support 1, which enhances the stability of the entire structure, and can more effectively disperse and transfer stress, and in the subsequent replacement of some parts, it can avoid the collapse or tilt of the end support 1. Specifically, Figure 1 and Figure 2 As shown, the first hook assembly includes a manual fall chain 3 and a steel wire rope 7, the second hook assembly includes a cable 2, the first limit assembly includes a clamping hook plate 10, and the second limit assembly includes a bolt 4 and a clamp 16; wherein, one end of the manual fall chain 3 is connected to the top of the end support 1 through the steel wire rope 7, and during this connection process, in order to improve the firmness of the connection, a fixed block 8 is installed on the steel wire rope 7, and the end of the fixed block 8 protrudes outward, and a movable groove is provided on the protrusion, and the hook at one end of the manual fall chain 3 close to the end support 1 is movably connected to the movable groove; a reinforced clamp 6 is installed on the side of the top of the end support 1 away from the manual fall chain 3, and the steel wire rope 7 is connected to the reinforced clamp 6; the other end of the manual fall chain 3 is connected to the clamping hook plate 10 through an interlocking assembly, and the end of the clamping hook plate 10 is connected to the top of the anchor plate 9. As shown Figure 2 and Figure 3As shown, bolts 4 are arranged at both ends of the inclined cable 2, and the end of one of the bolts 4 is connected to a tension plate 5, which is connected to the top of the end support 1 and the side away from the reinforcing clamp 6; and the end of the other bolt 4 is also connected to the top of the anchor plate 9, and clamps 16 are arranged on both bolts 4. The load of the inclined cable 2 is dispersedly transferred to the end support 1 and the anchor plate 9 through the bolts 4, avoiding the situation where a single point is subjected to excessive force. This dispersed load transfer method helps to protect the inclined cable 2 from damage and improves the bearing capacity of the structure. Figure 2-Figure 5 As shown, a pull plate 5 is also provided on the top of the anchor plate 9, and the pull plate 5 is vertically installed on the top of the anchor plate 9, and another bolt 4 is rotatably connected to the pull plate 5; there are two clamping hook plates 10, and the two clamping hook plates 10 are symmetrically arranged on both sides of the pull plate 5, and the two clamping hook plates 10 are both composed of a clamping plate 18; the first limiting component also includes a pin 11 and a connecting column 19; wherein, one end of the two clamping hook plates 10 is provided with a socket 20 and a pin hole 21, and the two sockets 20 are connected by a connecting column 19, and the connecting column 19 is a hollow structure; in the connecting column 19, a horizontal axis 15 is rotatably connected, and the two ends of the horizontal axis 15 are connected by a semicircular rod 14, and the semicircular rod 14 is connected to the interlocking component; and, the pin hole 21 is installed with the pin 11; its As can be seen from the figure, the interlocking assembly includes two large circular rings 12, both of which are U-shaped structures, and the blocking ends of the two large circular rings 12 are movably connected, and the open end of one of the large circular rings 12 cooperates with the hook at the end of the manual fall chain 3, and the hook is locked by the anchor 13; and the outer side of the other end of the two clamping hook plates 10 is provided with a horizontal axis 15, and the two horizontal axes 15 are connected by a semicircular rod 14, and the open end of the other large circular ring 12 cooperates with the semicircular rod 14, and the semicircular rod 14 is also locked by the anchor 13. In the locking process, the outer side of the other bolt 4 abuts against the inner side of the two clamping hook plates 10. To a certain extent, the first limit assembly and the second limit assembly limit each other. Figure 2-Figure 4 The bolt 4 is a structure with one end open and the other end blocked, and a clamp 16 is arranged on the open end of the bolt 4. At the same time, a fastening nut 17 is also arranged on the open end of the bolt 4. The clamp 16 and the fastening nut 17 work together to effectively prevent the inclined cable 2 from being separated and broken. Figure 3-Figure 6 As shown, the clamping hook plate 10 is an L-shaped structure, and one end of the pin 11 is set between the two clamping hook plates 10, close to the anchor plate 9; the L-shaped clamping hook plate 10 can better fit and hook the edges of the bolt 4 and the anchor plate 9, providing a greater limiting force. Finally, the plate includes a flat plate, which is set on the top of the end support 1 and is used to place a digital angle ruler. After the parts in the first hook assembly or the second hook assembly are replaced, the digital angle ruler is used to detect whether the vertical angle between the end support 1 and the ground has changed, so as to determine whether the end support 1 has a risk of tilting or collapse.
[0029] In a second aspect, an embodiment of the present invention provides a method for using a photovoltaic flexible bracket oblique structure, wherein the method is performed using the photovoltaic flexible bracket oblique structure as described above. Figure 7 As shown, including: S101. Use the first hook assembly and the second hook assembly to connect the end support pillar and the anchor plate; illustratively, the anchor plate 9 is embedded in advance, and then one end of the first hook assembly and the second hook assembly are connected to the end support pillar 1, and the other end is connected to the anchor plate 9, thereby forming a double support structure.
[0030] S102. While recording the verticality of the end support, pull the first hook assembly to check and replace the parts in the second hook assembly; illustratively, after the end support 1 and the anchor plate 9 are fixed, first install a flat plate at the bottom of the end support 1, and then place a digital angle ruler at the bottom of the flat plate to record the vertical angle between the current end support 1 and the ground; at this time, if it is detected that some parts in the first hook assembly or the second hook assembly need to be replaced, for example, when replacing the inclined cable 2, the bolt 4 and the clamp 16, first manually operate the manual fall chain 3 to make the manual fall chain 3 apply a certain tension to the end support 1 until the tension can replace the tension of the inclined cable 2 on the end support 1, and then immediately disassemble and replace the original inclined cable 2, bolt 4 and clamp 16; and, while disassembling and replacing, install the new inclined cable 2, bolt 4 and clamp 16; it is worth noting that the replacement of other parts is the same as the above-mentioned replacement steps and will not be elaborated in detail.
[0031] S103, after the inspection and replacement, loosen the first hook assembly and observe whether the verticality of the end support has changed. For example, when the parts that need to be replaced are replaced, in order to avoid the end support 1 being affected by the parts replacement factor during the subsequent photovoltaic flexible support support process, thereby causing the end support 1 to tilt or collapse; first slowly loosen the first hook assembly to release the excess tension, and then use the digital angle ruler again to check the verticality of the end support 1 and the ground. If the verticality of the second test is the same as the initial verticality, it means that the replacement operation is successfully completed.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
