Description

Technical Field

[0001] This invention belongs to the field of photovoltaic equipment technology, specifically relating to a flexible support structure and method for building photovoltaics. Background Technology

[0002] Flexible photovoltaic (PV) brackets are an innovative support system for solar photovoltaic (PV) modules, characterized by their lightweight, flexibility, and ease of installation. These brackets are typically made of weather-resistant materials, allowing them to adapt flexibly to various terrains and environmental conditions, reducing the weight and cost of fixed supports while also facilitating transportation and installation. Flexible PV brackets are widely used in rooftops, temporary power stations, and other variable installation scenarios, enhancing the overall efficiency and applicability of PV systems.

[0003] The reason why flexible photovoltaic (PV) mounting systems are suitable for building rooftops lies in their lightweight and flexible design. These systems require no complex infrastructure or reinforcement and can be directly installed on existing roofs, thus reducing the burden on the building structure. At the same time, the installation process of flexible systems is relatively simple, enabling rapid response to site conditions and needs, and maximizing the use of available roof space.

[0004] Chinese patent application number 202510525566.4 discloses a flexible photovoltaic support based on a large-span steel cable structure, comprising: two symmetrically distributed main support members, with two symmetrically distributed steel cables fixedly connected between the two main support members, and several photovoltaic panels jointly mounted on the two steel cables; a mounting base disposed between the two main support members; two symmetrically distributed fixed columns, each fixedly connected to the mounting base; and two symmetrically distributed second support frames, each disposed on adjacent fixed columns. The second support frames are provided with sliding grooves, and fixed members are slidably connected to the sliding grooves of the second support frames. Elastic liquid bladders are fixedly connected to the fixed members, and compression rings are slidably connected to the fixed members. This patent buffers the vibration of the steel cables by deforming the compression rings and the elastic liquid bladders, reducing the vibration amplitude of the steel cables, thereby weakening the dynamic stress superposition of the steel cables at adjacent compression rings, alleviating fatigue effects, and improving the overall structural stability.

[0005] When using flexible photovoltaic (PV) brackets on building rooftops, individual PV panels are typically fixed to steel cables. This not only takes up space but also leaves large gaps between panels, failing to provide rain protection and hindering residents' use of the rooftop space. While some compact installations meet some rain protection needs, the swaying structure of the steel cables makes the panels prone to collisions and damage. Furthermore, while some fixed, integrated PV panel installations meet rain protection needs, they are difficult to adjust, hinder drying during dry seasons, and are inconvenient for individual installation, disassembly, and maintenance. Additionally, if a single panel is damaged and repair is needed without a spare, direct disassembly compromises the stability of the PV panel and fails to maintain its rain protection effect, affecting residents' use of the rooftop. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a flexible support structure and method for building-integrated photovoltaics (BIPV). Through the cooperation of the installation mechanism and the photovoltaic panel, this invention maintains the independent connection of each photovoltaic panel, facilitating installation and disassembly while achieving seamless rain protection. It is suitable for installation on building roofs and ensures the buffer stability of each photovoltaic panel, preventing damage. Furthermore, through the cooperation of temporary limiting components with the photovoltaic panel and installation mechanism, this invention allows for rapid disassembly and maintains the stability of the photovoltaic panel while preserving its rain-protection effect in the event of accidental damage to a single photovoltaic panel without a spare. Finally, through the cooperation of the column and deflection mechanism, this invention facilitates the installation and shaping of the photovoltaic panel's sloping roof and allows for easy posture adjustment, improving safety and significantly enhancing the convenience of residents' drying activities.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Furthermore, the slider is fixedly provided with blocking blocks at both ends, and the blocking blocks are provided with drainage holes; the outer end of the abutment plate is fixedly connected with a rubber strip, and multiple second buffer springs are evenly fixed on the side wall of the slider above the abutment plate, and the ends of the second buffer springs are fixedly provided with buffer plates.

[0012] Furthermore, a limiting ring is fixedly provided at one end of the limiting nut, and the limiting ring abuts against the buffer spring; the end of the screw has a screw opening and a limiting baffle is provided below the end, and the limiting baffle is fixed to the end of the screw by screws.

[0013] Furthermore, the blocking block is fixedly provided with an ear plate, and the two ends of the elastic rope are fixedly provided with buckles, which are fastened to the ear plate.

[0014] Furthermore, the structure also includes a temporary limiting component, which includes a temporary limiting plate. The width of the temporary limiting plate is twice the width of the limiting plate, and two pairs of second screws are fixedly provided at the bottom of the temporary limiting plate.

[0015] Furthermore, the column includes a column body, the top of which is provided with a threaded circular groove, and a threaded column is screwed into the threaded circular groove; the top of the threaded column is provided with a T-shaped groove, and a T-shaped block is fixedly provided at the bottom of the support plate, the T-shaped block being rotatably connected to the T-shaped groove; the side wall of the column body is symmetrically provided with threaded holes, which communicate with the threaded circular groove; a limit screw is screwed into the threaded hole.

[0016] Furthermore, a fixing plate is fixedly provided at the bottom of the column body, and the fixing plate is fixedly connected to the building roof by anchor bolts around its perimeter.

[0017] A method for supporting a building-integrated photovoltaic (BIPV) flexible support structure includes the following steps:

[0018] S1. During installation, multiple pairs of columns and corresponding deflection mechanisms are installed at equal intervals on the building roof. One end of the steel wire rope group is connected to one of the deflection mechanisms, and then multiple installation mechanisms are threaded through it. The other end of the steel wire rope group is then connected to another deflection mechanism. Next, the limit plate above the installation mechanism is pulled to hang the straight slot of the photovoltaic panel on the limit rod. The limit plate is then loosened and the limit nut is tightened. Finally, the installation mechanism behind the array is connected to the adjacent front installation mechanism through the elastic rope.

[0019] S2. When it rains, the deflection mechanism deflects the photovoltaic panels at the rear of the array so that the lower part of each panel is directly above the higher part of the adjacent front photovoltaic panel to block the rain. When it is not raining, the deflection mechanism simultaneously opens all photovoltaic panels clockwise, increasing the gap between the photovoltaic panels on adjacent pairs of columns to facilitate drying. When it is windy, the photovoltaic panels on the even-numbered arrays are rotated clockwise first, and then the photovoltaic panels on the odd-numbered arrays are rotated counterclockwise to achieve an integrated wave structure.

[0020] S3. When one of the photovoltaic panels is damaged, remove the limiting nuts on both sides of the mounting mechanism of the damaged photovoltaic panel, and quickly remove the photovoltaic panel and the limiting plate; then remove the elastic rope at the end of the mounting mechanism on the corresponding array, and push the photovoltaic panel of the corresponding array so that the two mounting mechanisms at the point where the photovoltaic panel was removed are still attached together; then reconnect the two mounting mechanisms by replacing the temporary limiting plate, and adjust the clamps on the wire rope group for limiting; finally, reconnect all the elastic ropes for quick adjustment.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This invention, through the cooperation of the installation mechanism and the photovoltaic panel, can maintain the independent connection of a single photovoltaic panel, which is convenient for installation and disassembly, and can also achieve seamless rain protection. It is suitable for installation on building roofs and can also ensure the buffer stability of each photovoltaic panel so as not to be damaged. Specifically, during installation, multiple pairs of columns and corresponding deflection mechanisms are installed at equal intervals on the building roof. One end of the steel wire rope group is connected to one of the deflection mechanisms, and then multiple installation mechanisms are passed through. Then the other end of the steel wire rope group is connected to another deflection mechanism. Next, the limiting plate above the installation mechanism is pulled, and the straight groove of the photovoltaic panel is hung on the limiting rod. The limiting plate is loosened and the limiting nut is tightened. In this way, the photovoltaic panel can be installed independently through the movable limiting of the limiting rod and the elastic clamping of the limiting plate. When it is necessary to disassemble independently, the limiting nuts on the installation mechanisms on both sides of the photovoltaic panel can be removed to quickly remove the photovoltaic panel and the limiting plate for easy disassembly. At the same time, through the cooperation of the limiting plate, the abutment plate, and the rubber strip, a blocking space can be formed. When rainwater flows between two photovoltaic panels, the water will enter the abutment plate, The space between the rubber strips, and because the lower part of the photovoltaic panel at the rear of the array is directly above the higher part of the adjacent front photovoltaic panel, all water flowing out is caught by the lower photovoltaic panel, achieving a seamless rainproof effect. This is suitable for installation on building roofs and for residents' activities and drying clothes. Furthermore, while ensuring independent connection and seamless rainproofing, each photovoltaic panel is not rigidly fixed. In the event of strong winds or swaying of the steel cable assembly causing adjacent photovoltaic panels to collide, the limiting plate and buffer spring can cushion the photovoltaic panels from being damaged by the collision. At the same time, the limiting rod can also slightly hook the straight groove of the photovoltaic panel. Together with the limiting plate, it plays a buffer connection role. No matter how the photovoltaic panel shakes, under the limiting stroke of the buffer spring, the straight groove of the photovoltaic panel can never be disengaged from the limiting rod, further preventing the photovoltaic panel from falling off and being damaged. At the same time, the elastic rope connects the installation mechanism at the rear of the array with the adjacent front installation mechanism into a whole, so that the individual photovoltaic panel has a certain buffering effect in the up, down, left, right, and front and back, greatly improving the buffering stability and thus preventing damage.

[0023] (2) This invention, through the cooperation of temporary limiting components with photovoltaic panels and installation mechanisms, enables rapid disassembly and maintenance of the stability of photovoltaic panels when a single photovoltaic panel is accidentally damaged and no spare panel is available, while maintaining the rainproof effect. Specifically, when one photovoltaic panel is damaged, the limiting nuts on both sides of the installation mechanism of the damaged photovoltaic panel are removed, and the photovoltaic panel and limiting plate are quickly removed for easy repair. However, if there is no spare photovoltaic panel at this time, it cannot be replaced immediately. At this time, the photovoltaic panel area already has a gap, which greatly reduces the overall stability and is very likely to cause a chain of damage problems. Moreover, the rain leakage problem caused by the gap affects the residents' use of the roof. At this time, since each photovoltaic panel of this application is movable, For independent installations, simply remove the elastic ropes from the ends of the mounting mechanisms on the corresponding array and push the photovoltaic panels of the corresponding array so that the two mounting mechanisms at the point where the photovoltaic panels were removed are still attached together. Then, by replacing the second screw of the temporary limiting plate and inserting it into the limiting holes of the two mounting mechanisms, the two mounting mechanisms are reconnected, and the clamps at both ends of the wire rope group are adjusted for limiting. Finally, reconnecting all the elastic ropes allows for quick adjustment, enabling the photovoltaic panels to quickly become a whole again and maintain the stability of the photovoltaic panels. Furthermore, the rubber strips between the two connected mounting mechanisms seal against each other, forming a barrier space and preventing rain leakage, thus maintaining the rainproof effect and not affecting residents' use of the rooftop.

[0024] (3) This invention, through the cooperation of the column and the deflection mechanism, can facilitate the installation and shaping of the photovoltaic panel at an angle, and also facilitate posture adjustment, thereby improving safety and greatly enhancing the convenience of residents' drying life. Specifically, before installation, the height can be quickly changed by rotating the threaded column and locking the limit screw. After installation, since the lower part of the photovoltaic panel in the array direction needs to be directly above the higher part of the adjacent front photovoltaic panel and the photovoltaic panel is at an angle, in order to avoid the subsequent deflection collision problem of the deflection mechanism, there are strict requirements on the height of each pair of columns. If the height cannot be adjusted after installation, it will bring adjustment difficulty. In this application, if the height is found to be unsuitable after the photovoltaic panel is installed, the threaded column can be rotated slightly by external tools. At this time, due to the safety of the installation, the height of the photovoltaic panel at an angle can be adjusted. The installation mechanism and photovoltaic panels are already installed and have a limiting function. Therefore, the rotation of the threaded column can only change the height of the deflection mechanism without affecting the position of the photovoltaic panels, thus facilitating posture adjustment. Furthermore, when it rains, the deflection mechanism ensures that the lower part of the photovoltaic panels at the rear of the array is directly above the higher part of the adjacent front photovoltaic panels, providing rain protection. When it is not raining, the deflection mechanism simultaneously opens all photovoltaic panels clockwise, increasing the gap between photovoltaic panels on adjacent pairs of columns for easier drying. When it is windy, the photovoltaic panels on the even-numbered arrays are rotated clockwise first, and then the photovoltaic panels on the odd-numbered arrays are rotated counterclockwise, creating an integrated wave structure that reduces the contact area with the wind and greatly improves the windproof effect. This adjustment method improves safety while greatly enhancing the convenience of residents' drying activities. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items. Example

[0039] like Figures 1-10 As shown, a flexible support structure for building-integrated photovoltaics (BIPV) includes multiple pairs of columns 100 fixedly installed on the roof of a building. Each pair of columns 100 is equipped with a deflection mechanism 300, and each pair of deflection mechanisms 300 is fixedly connected to a steel wire rope group 800. Multiple installation mechanisms 400 are slidably connected to the steel wire rope group 800, and photovoltaic panels 200 are installed between adjacent installation mechanisms 400. The height of each pair of columns 100 increases sequentially in the array direction, and the photovoltaic panels 200 on each pair of columns 100 have the same tilt angle. The lower part of the photovoltaic panel 200 at the rear in the array direction is directly above the higher part of the adjacent front photovoltaic panel 200, and the installation mechanism 400 at the rear of the array is connected to the adjacent front installation mechanism 400 by an elastic rope 700. The installation mechanisms 400 at both ends of each steel wire rope group 800 are limited by clamps 820 on the steel wire rope group 800.

[0040] This invention, through the cooperation of the installation mechanism 400 and the photovoltaic panel 200, can maintain the independent connection of each photovoltaic panel 200, which is convenient for installation and disassembly, while also achieving seamless rain protection. It is suitable for installation on building roofs and can also ensure the buffer stability of each photovoltaic panel 200 so that it is not damaged; a detailed description will follow.

[0041] Furthermore, the deflection mechanism 300 includes a support plate 310 mounted on the top of the column 100. A rotating groove 320 is fixedly connected to the middle of the top of the support plate 310, and a deflection rod 330 is rotatably connected to the rotating groove 320 via a rotating shaft. A hydraulic telescopic rod 500 is hinged to one side of the top of the support plate 310 via a hinge groove 510, and the other end of the hydraulic telescopic rod 500 is hinged to one side of the deflection rod 330 via the hinge groove 510. Through holes 331 are provided at both ends of the deflection rod 330. The wire rope assembly 800 includes two wire ropes 810, the ends of which pass through the through holes 331 and are limited by a clamp 820.

[0042] By extending and retracting the hydraulic telescopic rod 500, the deflection rod 330 is controlled to deflect synchronously, thereby driving the wire rope 810 and the photovoltaic panel 200 to rotate synchronously.

[0043] It is worth noting that the hydraulic telescopic rod 500 of the present invention is powered by an external power source, which is a conventional setting and will not be described in detail here.

[0044] Further, the installation mechanism 400 includes a slider 420; a set of sliding holes 422 are provided through the side wall of the slider 420 and are slidably connected to the wire rope assembly 800; a pair of limiting holes 421 are provided through the top of the slider 420, a limiting plate 410 is provided above the slider 420, a pair of screws 411 are fixedly connected to the bottom of the limiting plate 410, the screws 411 pass through the limiting holes 421 and the ends are screwed with limiting nuts 490; a buffer spring 480 is sleeved between the limiting nut 490 and the slider 420; an abutment plate 430 is symmetrically fixedly connected to the middle of the side wall of the slider 420, a pair of limiting rods 470 are symmetrically fixedly connected to the top of the abutment plate 430; a frame 210 is fixedly installed around the photovoltaic panel 200, and straight slots 211 are symmetrically opened on both sides of the frame 210, the straight slots 211 are hung on the limiting rods 470.

[0045] Furthermore, the slider 420 is fixedly provided with blocking blocks 440 at both ends, and the blocking blocks 440 are provided with drainage holes 441; the outer end of the abutment plate 430 is fixedly connected with a rubber strip 460, and multiple second buffer springs 450 are evenly fixed on the side wall of the slider 420 above the abutment plate 430, and the end of the second buffer spring 450 is fixedly provided with a buffer plate 451.

[0046] During installation, multiple pairs of columns 100 and corresponding deflection mechanisms 300 are installed at equal intervals on the building roof. One end of a steel wire rope assembly 800 is connected to one of the deflection mechanisms 300, and then multiple installation mechanisms 400 are threaded through it. The other end of the steel wire rope assembly 800 is then connected to another deflection mechanism 300. Next, the limiting plate 410 above the installation mechanism 400 is pulled to hang the straight slot 211 of the photovoltaic panel 200 on the limiting rod 470. The limiting plate 410 is then released and the limiting nut 490 is tightened. Thus, the limiting rod 470 and the limiting plate 410 are used to limit the movement of the limiting rod 470 and the spring of the limiting plate 410. The photovoltaic panel 200 is clamped in place, allowing for independent installation. When independent disassembly is required, the limiting nuts 490 on both sides of the mounting mechanism 400 of the photovoltaic panel 200 can be removed to quickly remove the photovoltaic panel 200 and the limiting plate 410 for easy disassembly. Simultaneously, the limiting plate 410, the abutment plate 430, and the rubber strip 460 work together to create a blocking space. When rainwater flows between two photovoltaic panels 200, the water enters the space between the abutment plate 430 and the rubber strip 460. Furthermore, because the lower part of the rear photovoltaic panel 200 in the array direction is located at the adjacent front photovoltaic panel... Located directly above the photovoltaic panels 200 at a height of 200 meters, all water flowing out is caught by the photovoltaic panels 200 below, achieving a seamless rainproof effect. This is suitable for installation on building roofs and for residents' activities and drying of clothes. Furthermore, while ensuring independent connection and seamless rainproofing, each photovoltaic panel 200 is not rigidly fixed. In the event of strong winds or swaying of the steel cable assembly 800 causing adjacent photovoltaic panels 200 to collide, the limiting plate 410 and the buffer spring 480 can cushion the photovoltaic panels 200 from being damaged by the collision, while the limiting rod 470 can also slightly hook the photovoltaic panels 200. The straight slot 211 of the photovoltaic panel 200, together with the limiting plate 410, serves as a buffer connection. At the same time, no matter how the photovoltaic panel 200 is shaken, under the limiting stroke of the buffer spring 480, the straight slot 211 of the photovoltaic panel 200 can never be separated from the limiting rod 470, further preventing the photovoltaic panel 200 from falling off and being damaged. Meanwhile, the elastic rope 700 connects the mounting mechanism 400 behind the array with the adjacent mounting mechanism 400 in front to form a whole, so that the individual photovoltaic panel 200 has a certain buffering effect in the up and down, left and right, and front and back, which greatly improves the buffering stability and prevents it from being damaged.

[0047] Furthermore, a limiting ring 491 is fixedly provided at one end of the limiting nut 490, and the limiting ring 491 abuts against the buffer spring 480; the end of the screw 411 is provided with a screw hole and a limiting baffle 492 is provided below the end, and the limiting baffle 492 is fixed to the end of the screw 411 by screws.

[0048] The limiting baffle 492 further prevents the limiting nut 490 from falling off, preventing it from loosening and falling off after a long period of use; and, even after the limiting nut 490 falls off, the blocking block 440 can still play a certain limiting role on the photovoltaic panel 200 due to its structural design, preventing the photovoltaic panel 200 from falling and breaking directly.

[0049] Furthermore, an ear plate 442 is fixedly provided on the blocking block 440, and a locking buckle 720 is fixedly provided at both ends of the elastic rope 700, the locking buckle 720 fastening onto the ear plate 442. The structural design of the locking buckle 720 facilitates quick disassembly and installation.

[0050] Furthermore, the structure also includes a temporary limiting component 900, which includes a temporary limiting plate 910. The width of the temporary limiting plate 910 is twice the width of the limiting plate 410, and two pairs of second screws 920 are fixedly provided at the bottom of the temporary limiting plate 910.

[0051] This invention, through the cooperation of the temporary limiting component 900 with the photovoltaic panel 200 and the mounting mechanism 400, enables rapid disassembly and maintains the stability of the photovoltaic panel 200 while preserving its rain-proof effect when a single photovoltaic panel 200 is accidentally damaged and no spare panel is available. Specifically, when one photovoltaic panel 200 is damaged, the limiting nuts 490 on both sides of the mounting mechanism 400 of the damaged photovoltaic panel 200 are removed, and the photovoltaic panel 200 and the limiting plate 410 are quickly removed for easy repair. However, if no spare photovoltaic panel 200 is available, it cannot be replaced immediately. At this time, the area of ​​the photovoltaic panel 200 has a gap, which greatly reduces the overall stability and is very likely to cause cascading damage. Moreover, the rain leakage caused by the gap affects residents' use of the roof. In this case, since each photovoltaic panel 200 in this application is independently and movable, Simply remove the elastic rope 700 from the end of the mounting mechanism 400 on the corresponding array and push the photovoltaic panel 200 of the corresponding array so that the two mounting mechanisms 400 at the point where the photovoltaic panel 200 was removed are still attached together; then, by replacing the second screw 920 of the temporary limiting plate 910 and inserting it into the limiting hole 421 of the two mounting mechanisms 400, the two mounting mechanisms 400 are reconnected, and the clamps 820 at both ends of the wire rope group 800 are adjusted for limiting; finally, by reconnecting all the elastic ropes 700, the photovoltaic panel 200 can be quickly adjusted to quickly become a whole again, and the stability of the photovoltaic panel 200 can always be maintained; in addition, the rubber strip 460 between the two connected mounting mechanisms 400 is sealed together, forming a blocking space, which can also prevent rain leakage and maintain the rainproof effect, thus not affecting the residents' use of the roof.

[0052] Furthermore, the column 100 includes a column body 110, the top of which is provided with a threaded circular groove 112, and the threaded circular groove 112 is screwed onto a threaded column 140; the top of the threaded column 140 is provided with a T-shaped groove 141, and the bottom of the support plate 310 is fixedly provided with a T-shaped block 340, which is rotatably connected to the T-shaped groove 141; the side wall of the column body 110 is symmetrically provided with threaded holes 111, which communicate with the threaded circular groove 112; a limit screw 130 is screwed onto the threaded hole 111.

[0053] This invention, through the cooperation of the column 100 and the deflection mechanism 300, facilitates the installation and shaping of the photovoltaic panel 200 at an angle, and also facilitates posture adjustment, improving safety and greatly enhancing the convenience of residents' drying activities. Specifically, before installation, the height can be quickly changed by rotating the threaded column 140 and locking the limiting screw 130. After installation, since the lower part of the photovoltaic panel 200 in the array direction needs to be directly above the higher part of the adjacent front photovoltaic panel 200, and the photovoltaic panel 200 is at an angle, strict requirements are needed on the height of each pair of columns 100 to avoid subsequent deflection collisions of the deflection mechanism 300. If the height cannot be adjusted after installation, it will bring adjustment difficulties. However, in this application, if the height is found to be unsuitable after the photovoltaic panel 200 is installed, the threaded column 140 can be slightly rotated using an external tool. At this time, due to the installation mechanism 40 Since the photovoltaic panels 200 and 0 are already installed and have a limiting function, the rotation of the threaded column 140 can only change the height of the deflection mechanism 300 without affecting the position of the photovoltaic panels 200, thus facilitating posture adjustment. Furthermore, when it rains, the deflection mechanism 300 deflects the photovoltaic panels 200 at the rear of the array so that the lower part of each panel is directly above the upper part of the adjacent front panel 200, providing rain protection. When it is not raining, the deflection mechanism 300 simultaneously opens all the photovoltaic panels 200 clockwise, increasing the gap between the photovoltaic panels 200 between adjacent pairs of columns 100, thus facilitating drying. When it is windy, the photovoltaic panels 200 on the even-numbered arrays are rotated clockwise first, and then the photovoltaic panels 200 on the odd-numbered arrays are rotated counterclockwise, creating an integrated wave structure that reduces the contact area with the wind and greatly improves the windproof effect. This adjustment method improves safety while greatly enhancing the convenience of residents' drying activities.

[0054] Furthermore, a fixing plate 120 is fixedly provided at the bottom of the column body 110, and the fixing plate 120 is fixedly connected to the building roof by anchor bolts 121 around its perimeter. The column body 110 is fixed to the building roof through the fixing plate 120 and the anchor bolts 121.

[0055] A method for supporting a building-integrated photovoltaic (BIPV) flexible support structure includes the following steps:

[0056] S1. During installation, multiple pairs of columns 100 and corresponding deflection mechanisms 300 are installed at equal intervals on the building roof. One end of the wire rope group 800 is connected to one of the deflection mechanisms 300, and then multiple installation mechanisms 400 are threaded through it. The other end of the wire rope group 800 is then connected to another deflection mechanism 300. Next, the limiting plate 410 above the installation mechanism 400 is pulled to hang the straight slot 211 of the photovoltaic panel 200 on the limiting rod 470. The limiting plate 410 is then released and the limiting nut 490 is tightened. Finally, the installation mechanism 400 behind the array is connected to the adjacent front installation mechanism 400 through the elastic rope 700.

[0057] S2. When it rains, the deflection mechanism 300 deflects the photovoltaic panels 200 at the rear of the array so that the lower part of each panel is directly above the upper part of the adjacent front photovoltaic panel 200 to block the rain. When it is not raining, the deflection mechanism 300 simultaneously opens all the photovoltaic panels 200 clockwise, increasing the gap between the photovoltaic panels 200 between two pairs of adjacent columns 100 to facilitate drying. When it is windy, the photovoltaic panels 200 on the even-numbered arrays are rotated clockwise first, and then the photovoltaic panels 200 on the odd-numbered arrays are rotated counterclockwise to achieve an integrated wave structure.

[0058] S3. When one of the photovoltaic panels 200 is damaged, remove the limiting nuts 490 on the mounting mechanisms 400 on both sides of the damaged photovoltaic panel 200, and quickly remove the photovoltaic panel 200 and the limiting plate 410; then remove the elastic rope 700 at the end of the mounting mechanism 400 on the corresponding array, and push the photovoltaic panel 200 of the corresponding array so that the two mounting mechanisms 400 at the location where the photovoltaic panel 200 was removed are still attached together; then reconnect the two mounting mechanisms 400 by replacing the temporary limiting plate 910, and adjust the clamp 820 on the wire rope group 800 for limiting; finally, reconnect all the elastic ropes 700 for quick adjustment.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
