Description

Technical Field

[0001] The invention relates to the field of flexible brackets, in particular to a flexible bracket cable structure and a flexible bracket. Background Art

[0002] Photovoltaic modules, namely solar panels, are the core part of solar power generation systems and require photovoltaic brackets for installation. The installation method and bracket structure have an important impact on the efficiency and stability of the entire system. Flexible brackets can achieve elevated, large spans, and secondary land utilization, and are safe, reliable, economical, and applicable.

[0003] Existing flexible photovoltaic brackets mostly use suspension cables as supporting load-bearing structures, and usually use multiple parallel suspension cables to suspend photovoltaic panels, and the photovoltaic panels are directly overlapped and set on each suspension cable.

[0004] With respect to the above-mentioned related technologies, the cable structure of the existing photovoltaic panel flexible bracket is prone to causing the photovoltaic panel to shake due to the elastic force of the cable itself in harsh environments such as strong airflows, and the wind direction of the strong airflow may change at any time, and the force exerted by the wind on the photovoltaic panel is not constant, resulting in the existing cable or the connection of the cable being easily torn apart due to strong winds. In summary, the cable structure of the existing flexible bracket is not easy to stably suspend the photovoltaic panel. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a flexible support cable structure and a flexible support to solve the technical problem that the existing flexible support cable structure is not stable enough to suspend photovoltaic panels.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a flexible support cable structure, comprising at least two relatively arranged frames, the middle parts of the top ends of the frames are fixedly connected to a fixed platform, the fixed platforms are respectively connected to two second damping elastic members toward the two ends of the frames, fixed pulleys are provided at both ends of the top of the frames, the middle parts of the two frames are rotatably connected to a rotating frame, the two ends of the rotating frame are connected to a sling, and the ends of the sling are connected to the second damping elastic member after passing the fixed pulley.

[0007] By adopting the above technical solution, in severe weather with strong airflow, the rotating frame equipped with photovoltaic panels can reduce the windward area by rotating, thereby reducing the overall force on the frame. The damping elastic parts on the frame can play a good buffering role when the airflow exerts force on the rotating frame, effectively preventing the sling from being torn off or the connection of the sling from breaking.

[0008] The present invention is further configured such that a slideway is provided at the top of the frame, a protection box is slidably connected in the slideway, and positioning blocks for positioning the protection box are fixedly connected at both ends of the frame.

[0009] By adopting the above technical solution, the protective box can provide good protection for the second damping elastic member.

[0010] The present invention is further configured such that a portion of the second damping elastic member connected to the sling is slidably connected between an inner wall of the protection box and the frame.

[0011] By adopting the above technical solution, the end of the second damping elastic member can slide along the axial direction, thereby guiding the end of the second damping elastic member.

[0012] A flexible bracket comprises at least two frames arranged opposite to each other, a rotating frame is rotatably connected between the two frames, a slider is rotatably connected to the middle of the frame, sliding grooves are arranged on both sides of the rotating frame, the slider is slidably connected in the sliding grooves, a first damping elastic member is arranged between both ends of the slider and the inner wall of the sliding groove, the rotating frame is tiltedly arranged between the two frames, and the top and bottom ends are respectively connected to the frames by slings.

[0013] By adopting the above technical solution, the rotating frame can slide relative to the slider when subjected to strong airflow, so that the rotation axis position of the sliding frame is biased toward the windward direction, further improving the stability of the rotating frame in the windward state.

[0014] The present invention is further configured such that the top and bottom ends of the rotating frame are both fixedly connected with windshields, the windshield at the top end of the rotating frame is arranged on the top surface of the rotating frame, and the windshield at the bottom end of the rotating frame is arranged on the bottom surface of the rotating frame.

[0015] By adopting the above technical solution, after the windshield is affected by the airflow, the rotating frame can be quickly rotated along the preset direction to adjust the angle, thereby avoiding the situation where the rotating frame rotates uncontrollably due to the airflow.

[0016] The present invention is further configured such that a ventilating opening is provided in the middle of each windshield.

[0017] By adopting the above technical solution, the air vents are used to reduce the wind resistance of the wind shield when the air flow velocity is too fast, thereby avoiding excessive increase in external force on the frame due to the installation of the wind shield.

[0018] The present invention is further configured such that there are three frames in total, and two rotating frames are rotatably connected between the three frames.

[0019] By adopting the above technical solution, a required number of frames can be added between the frames on both sides according to design requirements.

[0020] The present invention is further configured such that a middle portion of the frame located in the middle is rotatably connected to the frames on both sides with a sliding block, and both sides of the top are fixedly connected to a fixing platform.

[0021] By adopting the above technical solution, except for the frames located at two sides, both sides of the remaining frames are provided with sliders, fixed pulleys and fixed platforms.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. The present invention arranges a damping elastic member in the frame, connects one end of the sling to the damping elastic member, and connects the other end to the rotating frame, so that the middle part of the rotating frame equipped with the photovoltaic panel is rotatably connected to the frame. In severe weather with strong airflow, the rotating frame equipped with the photovoltaic panel can reduce the windward area by rotating, thereby reducing the force on the entire frame. The damping elastic member on the frame can play a good buffering role when the airflow exerts force on the rotating frame, effectively preventing the sling from being torn off or the connection of the sling from being broken;

[0024] 2. The present invention provides a structure of a slide groove and a slider in the rotating frame, and provides damping elastic members at both ends of the slider in the slide groove. When the rotating frame is subjected to a strong airflow, it can slide relative to the slider, so that the rotation axis position of the sliding frame is biased toward the windward direction, further improving the stability of the rotating frame in the windward state;

[0025] 3. The present invention arranges wind shields facing the wind at the top and bottom of the rotating frame respectively, so that the rotating frame can be better rotated along a preset direction under the action of external airflow and the rotating axis of the rotating frame can be offset from the center position, which is conducive to the rotating frame quickly reaching a stable state in a windy environment and effectively preventing the rotating frame from being subjected to uncontrollable continuous rotation along the rotating axis due to the action of strong airflow.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Embodiment 1

The first damping elastic member 6 and the second damping elastic member 14 will play a buffering role when compressed or stretched, effectively preventing the sling 15 from breaking.
