Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0037] As Figures 1 - 6 shown, the anti-falling component disclosed in the present invention includes an anti-falling net 300 and a photovoltaic tetrahedron 600. Any side of the anti-falling net 300 is fixed by at least three nodes, including two end nodes and at least one middle node. The two end nodes are respectively arranged on the first bracket 100 and the second bracket 200, and the middle node is arranged on the photovoltaic tetrahedron 600 connected to the main cable 900. Specifically, the two end nodes and at least one middle node can form a three-point support for the anti-falling net 300, so that the anti-falling net 300 can be horizontally arranged below the photovoltaic module after connection to receive the photovoltaic module. Specifically, along the length direction of the anti-falling net 300, a plurality of photovoltaic tetrahedrons 600 can be arranged so that the anti-falling net 300 is in a tensioned state after installation, thereby ensuring the wind resistance of the anti-falling component. The anti-falling component provided by the present invention, the anti-falling net 300 is connected to the first bracket 100 and the second bracket 200 and is arranged below the photovoltaic module 400. When encountering extreme weather such as strong winds that cause the photovoltaic module 400 to fall, the anti-falling net 300 can receive the falling photovoltaic module 400 and play a buffering role, thereby protecting the photovoltaic module 400 from being damaged, and at the same time playing an anti-falling role for the photovoltaic module 400 to prevent it from falling from a high place and injuring people or passing vehicles, causing economic losses. Therefore, the safety of the photovoltaic system is improved.

[0038] To optimize the above technical solution, the four corners of the photovoltaic square pyramid 600 are respectively connected to the main cables 900, and its vertex is connected to the anti-falling net 300. Specifically, the main cables 900 of the photovoltaic modules are parallel to the length direction of the anti-falling net 300 and are the inherent structures of the photovoltaic modules. During use, the photovoltaic square pyramid 600 is inverted, and the four corners of its bottom respectively pass through two main cables 900 arranged in parallel with a group of photovoltaic modules and are connected to the main cables 900, and its vertex is connected to the anti-falling net 300 through a U-shaped bolt, thereby connecting the main cable 900 and the anti-falling net 300 together and improving the connection stability of the anti-falling net 300. Further, in the actual application environment, usually multiple groups of photovoltaic modules are arranged in parallel, and each group of photovoltaic modules includes two main cables 900. Therefore, there can be various connection methods between the photovoltaic square pyramid 600 and the anti-falling net 300. For example, the photovoltaic square pyramids 600 arranged in series on the main cables 900 of the same group of photovoltaic modules can be respectively connected to two adjacent anti-falling nets 300, so that multiple anti-falling nets 300 are arranged below multiple groups of photovoltaic modules of the flexible photovoltaic system, thereby improving the overall wind resistance of the anti-falling components and enabling them to resist extreme weather conditions such as strong winds.

[0039] In some embodiments of the present invention, the anti-falling component further includes a connecting member 700, a first ear plate 500, a second ear plate 501 and a steel wire rope 502. The first ear plate 500 is fixed to the first bracket 100, the second ear plate 501 is fixed to the second bracket 200, the first ear plate 500 and the second ear plate 501 are arranged opposite to each other, the first end of the steel wire rope 502 is connected to the first ear plate 500, the second end of the steel wire rope 502 is connected to the second ear plate 501, the anti-falling net 300 is connected to the steel wire rope 502 through the connecting member 700, and the steel wire rope 502 is connected to the main cable 900 through the photovoltaic square pyramid 600. That is, steel wire ropes 502 are arranged on both sides in the length direction of one anti-falling net 300, but at least one side of both sides in the length direction of one anti-falling net 300 is also connected to the vertex of the photovoltaic square pyramid 600, so as to form a structural form in which the anti-falling net 300 is not only connected to the steel wire rope 502 but also connected to the main cable 900 of the already installed and fixed photovoltaic module, thereby improving the wind resistance of the anti-falling component. Specifically, the first ear plate 500 and the second ear plate 501 can be respectively welded to the first bracket 100 and the second bracket 200. During use, the arrangement and extension direction of the steel wire rope 502 is parallel to the length direction of the anti-falling net 300, and the steel wire rope 502 is connected to the long side of the anti-falling net 300 to fix the anti-falling net 300. Such an arrangement can improve the connection stability of the anti-falling net 300, enable it to resist extreme weather conditions such as strong winds, and thus be able to support the photovoltaic module 400 and improve the safety of the photovoltaic system.

[0040] To optimize the above technical solution, the anti-falling component further includes a hoop. The number of hoops is multiple. The first ear plate 500 is connected to the first bracket 100 through the hoop, and the second ear plate 501 is connected to the second bracket 200 through the hoop. Specifically, when the hoop is used to connect the first ear plate 500 to the first bracket 100 or the second ear plate 501 to the second bracket 200, the first ear plate 500 and the second ear plate 501 do not need to be welded to the first bracket 100 and the second bracket 200. As a result, the hoop, the first ear plate 500, the second ear plate 501, and the steel wire rope 502 are all detachable structures. When installation, maintenance, or replacement is required, only the hoop needs to be tightened or loosened, thereby improving the maintainability and usage flexibility of the anti-falling component.

[0041] It should be noted that the main cable 900 is a connecting rope for connecting the photovoltaic quadrangular pyramids 600. Its first end is connected to the first bracket 100, then passes through the photovoltaic quadrangular pyramid 600 and is connected to the second bracket 200. Moreover, both ends of the main cable 900 can also be connected to the first bracket 100 and the second bracket 200 through ear plates. The main cable 900 is used to assist in fixing the photovoltaic quadrangular pyramid 600. During use, the vertices of one or more photovoltaic quadrangular pyramids 600 are connected to the steel wire rope 502 to form a dot-shaped fixation for the anti-falling net 300. By changing the arrangement positions and quantities of the photovoltaic quadrangular pyramids 600, the shape of the anti-falling net 300 after installation can be adjusted, so as to improve the usage flexibility of the anti-falling net 300 and prevent the photovoltaic modules 400 from scattering and tumbling on the anti-falling net 300 after falling, thereby further enhancing the safety of the photovoltaic system.

[0042] To optimize the above technical solution, the number of connecting pieces 700 is multiple. Each connecting piece 700 includes a pipe hoop 701 and a hanging buckle 702. The pipe hoop 701 is connected to the steel wire rope 502, and the hanging buckle 702 is connected to the anti-falling net 300. The pipe hoop 701 and the hanging buckle 702 are arranged in a double-loop buckle form. Specifically, the connecting pieces 700 are evenly arranged along the steel wire rope 502. During use, the pipe hoop 701 tightens the outer circumference of the steel wire rope 502, and the hanging buckle 702 is hooked to the anti-falling net 300 to achieve the movable connection between the steel wire rope 502 and the anti-falling net 300, as well as the multi-point connection to the anti-falling net 300, thereby improving the connection stability of the anti-falling net 300 and enabling it to resist harsh working conditions such as strong winds.

[0043] In some other embodiments of the present utility model, the anti-falling component further includes a first connecting plate, a second connecting plate and a slider 801. The first connecting plate is fixedly connected to the first bracket 100, and the second connecting plate is fixedly connected to the second bracket 200. A chute is provided in the length direction of the first connecting plate and the second connecting plate. The slider 801 is matched with the chute and can slide along the chute. The slider 801 is fixedly connected to the anti-falling net 300. Specifically, the chute can be in a form where the bottom of the chute is close to the first bracket 100 or the second bracket 200, and the two chute walls protrude and are bent relatively, so that the slider 801 can be clamped into the chute, and the two chute walls hold the slider 801, making it not easy to escape from the chute during the sliding process. During use, the slider 801 slides along the chute, driving the anti-falling net 300 to unfold or retract. The operator can determine the final arrangement position of the slider 801 according to the use requirements to adjust the laying area of the anti-falling net 300, thereby improving the application flexibility of the anti-falling component while ensuring the stable connection of the anti-falling net 300.

[0044] In some embodiments, the anti-falling component further includes bolts. A plurality of through holes are evenly provided in the chute walls of the chute, and positioning holes are provided in the side walls of the slider 801. The bolts are used to connect the through holes and the positioning holes. Specifically, the through holes and / or the positioning holes are threaded holes. During use, the operator slides the slider 801 inside the chute. When the slider 801 reaches the preset position, bolts are used to pass through the through holes and the positioning holes and tightened, so as to fix the slider 801 inside the chute, realizing the positioning of the anti-falling net 300. Such an arrangement enables the operator to judge the displacement of the slider 801 according to the interval distance of the through holes, so as to be able to position the relative positions of the two relatively arranged sliders 801, improve the unfolding efficiency of the anti-falling net 300, accurately calculate the unfolding area and position during installation, improve the installation efficiency of the anti-falling component, and at the same time improve the application flexibility of the anti-falling component.

[0045] Such as Figure 7 and Figure 8As shown, in some other embodiments, the chute is an inverted "convex" - shaped groove 800. A plurality of first arc - shaped teeth 802 are arranged at the bottom of the chute, and second arc - shaped teeth 803 are arranged on the side wall of the slider 801. The first end of the second arc - shaped tooth 803 is hinged to the side wall of the slider 801, and the second end hangs freely. When the slider 801 reaches a preset position, the first arc - shaped tooth 802 abuts against the second arc - shaped tooth 803. Specifically, the slider 801 slides on the step of the "convex" - shaped groove 800. Specifically, at least two sliders 801 are arranged in the same chute. The shapes of the first arc - shaped teeth 802 are in opposite directions. For example, when looking straight at the chute, the lower end of the first arc - shaped tooth 802 on the left side of the chute is fixed to the bottom of the groove, and its upper end extends to the left. The lower end of the first arc - shaped tooth 802 on the right side of the chute is fixed to the bottom of the groove, and its upper end extends to the right. At the same time, the arrangement of the second arc - shaped tooth 803 of the slider 801 on the left side is the same as that of the first arc - shaped tooth 802 on the left side of the chute, and the arrangement of the second arc - shaped tooth 803 of the slider 801 on the right side is the same as that of the first arc - shaped tooth 802 on the right side of the chute. When in use, because the first end of the second arc - shaped tooth 803 is hinged to the side wall of the slider 801 and the second end hangs freely, when the slider 801 on the left side slides to the left, the second arc - shaped tooth 803 slides across a plurality of first arc - shaped teeth 802 until the slider 801 on the left side reaches the preset position on the left side. At this time, the second arc - shaped tooth 803 on the slider 801 is on the left side of the first arc - shaped tooth 802. When the slider 801 has a tendency to move to the right, the first arc - shaped tooth 802 will abut against the second arc - shaped tooth 803, thereby limiting the position of the slider 801. It should be noted that the cooperation between the above - mentioned first arc - shaped tooth 802 and second arc - shaped tooth 803 can be understood by referring to the cooperation mode of ratchet and pawl. Further, a first fixing hole is opened on the slider 801, and a second fixing hole is opened at the bottom of the "convex" - shaped groove 800. When the first arc - shaped tooth 802 abuts against the second arc - shaped tooth 803, an operator can insert a rod - shaped object with a head into the fixing hole to further limit the position of the slider 801. Such an arrangement can reduce the steps of screwing to fix the slider 801 and the chute, thereby simplifying the installation process of the anti - falling component and improving its installation efficiency.

[0046] To optimize the above - mentioned technical solution, closing plates are arranged at both ends of the chute. The closing plates are detachably connected to the first connecting plate and / or the second connecting plate and are used to close the ends of the chute. Specifically, the closing plates are used to prevent the slider 801 from sliding out of both ends of the chute. That is, when encountering harsh working conditions such that the slider 801 is not fixed by the fixing device or the fixing device is damaged, the closing plates can serve as the last layer of fixing parts to catch the slider 801, thereby ensuring that the anti - falling net 300 can always be located below the photovoltaic module 400, and further improving the safety of the photovoltaic system.

The first end of the main cable 900 is connected to the first bracket 100, and its second end is connected to the second bracket 200.
