Description

Technical Field

[0001] This invention relates to the field of flexible stents, specifically to a flexible stent. Background Technology

[0002] Photovoltaic modules, or solar panels, are the core component of a solar power generation system. They require photovoltaic support structures for installation, and the installation method and structure of these structures have a significant impact on the efficiency and stability of the entire system. Flexible support structures can be used for elevated installations, large spans, and secondary land use, and are characterized by high safety, reliability, economy, and applicability.

[0003] Existing flexible photovoltaic supports mostly use suspension cables as the supporting load-bearing structure, and usually use multiple parallel suspension cables to suspend the photovoltaic panels, with the photovoltaic panels directly overlapping and set on each suspension cable.

[0004] Regarding the aforementioned technologies, existing flexible photovoltaic panel supports are prone to swaying in harsh environments such as strong airflow due to the elasticity of the suspension cables. Furthermore, the wind direction may change constantly, and the force exerted on the photovoltaic panels by the wind is not constant. This makes the existing suspension cables or their connections prone to being torn apart by strong winds. In summary, existing flexible supports are not suitable for stably suspending photovoltaic panels. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a flexible support to solve the technical problem of unstable suspension of photovoltaic panels by existing flexible supports.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible support, comprising at least two opposing frames, each frame having a fixed platform fixedly connected to its top center, and two second damping elastic elements connected to the fixed platforms at their respective ends facing the frames. Fixed pulleys are provided at both ends of the top of each frame. A rotating frame is rotatably connected to the middle of the two frames, with slings connected to both ends of the rotating frame. The ends of the slings pass over the fixed pulleys and are connected to the second damping elastic elements. A rotating frame is rotatably connected between the two frames, with a slider rotatably connected to the middle of each frame. Slide grooves are provided on both sides of the rotating frame, and the slider is slidably connected within the slide grooves. First damping elastic elements are provided between both ends of the slider and the inner wall of the slide groove. The rotating frame is inclined between the two frames, and its top and bottom ends are connected to the frames via slings.

[0007] By adopting the above technical solution, under severe weather conditions with strong airflow, the rotating frame equipped with photovoltaic panels can reduce the windward area by rotating, thereby reducing the overall stress on the frame. The damping elastic element on the frame can play a good role in buffering when the airflow exerts force on the rotating frame, effectively preventing the suspension cable from being torn or the connection of the suspension cable from breaking. When the rotating frame is subjected to strong airflow, it can slide relative to the slider, causing the rotation axis of the sliding frame to deviate towards the windward direction, further improving the stability of the rotating frame in the windward state.

[0008] The present invention is further configured such that a slide rail is provided at the top of the frame, a protective box is slidably connected in the slide rail, and positioning blocks for positioning the protective 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 element.

[0010] The invention is further configured such that the portion of the second damping elastic element connected to the sling is slidably connected between the inner wall of the protective box and the frame.

[0011] By adopting the above technical solution, the end of the second damping elastic element can slide along the axial direction, which plays a guiding role for the end of the second damping elastic element.

[0012] The present invention is further configured such that wind baffles are fixedly connected to both the top and bottom ends of the rotating frame, the wind baffle at the top of the rotating frame is disposed on the top surface of the rotating frame, and the wind baffle at the bottom of the rotating frame is disposed on the bottom surface of the rotating frame.

[0013] By adopting the above technical solution, the wind deflector can be made to rotate the rotating frame quickly in a preset direction to adjust the angle after being subjected to airflow, thus avoiding the situation where the rotating frame rotates uncontrollably under the influence of airflow.

[0014] The present invention is further configured such that each of the wind deflectors has a ventilation opening in the middle for ventilation.

[0015] By adopting the above technical solution, the vent is used to reduce the wind resistance of the baffle when the airflow speed is too fast, and to avoid excessive increase in the external force on the frame due to the installation of the baffle.

[0016] The present invention is further configured such that there are a total of three frames, and two rotating frames are rotatably connected between the three frames.

[0017] By adopting the above technical solution, the required number of frames can be added between the frames on both sides according to the design requirements.

[0018] The invention is further configured such that the middle part of the frame located in the middle is rotatably connected to the frames on both sides, and fixed platforms are fixedly connected to both sides of the top.

[0019] By adopting the above technical solution, in addition to the frames located on both sides, the other frames are equipped with sliders, fixed pulleys and fixed platforms on both sides.

[0020] In summary, the present invention has the following main beneficial effects:

[0021] 1. This invention provides a damping elastic element within the frame, connecting one end of the sling to the damping elastic element and the other end to the rotating frame, allowing the middle of the rotating frame containing the photovoltaic panel to be rotatably connected to the frame. In severe weather conditions with strong airflow, the rotating frame containing the photovoltaic panel can reduce its windward area by rotating, thereby reducing the overall stress on the frame. The damping elastic element on the frame can provide good buffering when the airflow exerts force on the rotating frame, effectively preventing the sling from being torn or the connection of the sling from breaking.

[0022] 2. The present invention uses a structure with a groove and a slider inside the rotating frame. Damping elastic elements are set at both ends of the slider inside the groove. When the rotating frame is subjected to strong airflow, it can slide relative to the slider, causing the rotation axis of the sliding frame to be biased towards the windward direction, thereby further improving the stability of the rotating frame in the windward state.

[0023] 3. By setting wind deflectors at the top and bottom of the rotating frame, the present invention enables the rotating frame to rotate better along the preset direction under the action of external airflow and causes the rotation axis of the rotating frame to deviate from the center position. This is beneficial for the rotating frame to quickly reach a stable state in strong winds and effectively avoids the rotating frame from being subjected to strong airflow and causing uncontrollable continuous rotation along the rotation axis.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of the present invention will now be described.

[0034] Example 1

[0035] A flexible stent, such as Figure 1-7 As shown, the system includes at least two opposing frames 1. Each frame 1 has a fixed platform 13 fixedly connected to the middle of its top. Each fixed platform 13 has two second damping elastic elements 14 connected to its two ends facing the frame 1. Each of the top ends of the frame 1 has a fixed pulley 11, which changes the direction of the tension of the sling 15. The middle of the two frames 1 is rotatably connected to a rotating frame 2. A photovoltaic panel body 3 is fixedly connected inside the rotating frame 2. Each end of the rotating frame 2 is connected to a sling 15, and the end of the sling 15 passes over the fixed pulley 11 and is connected to the second damping elastic element 14.

[0036] Please see Figure 1-6 The top of the frame 1 is provided with a slide rail 9, and a protective box 10 is slidably connected in the slide rail 9. Both ends of the frame 1 are fixedly connected with positioning blocks 12 for positioning the protective box 10. The protective box 10 can provide good protection for the second damping elastic member 14. Specifically, when installing the protective box 10, the protective box 10 is first slidably connected in the slide rail 9 at the top of the frame 1, and then the positioning blocks 12 are fixedly connected to both ends of the protective box 10 at the top of the frame 1. Specifically, the positioning blocks 12 are connected to the frame 1 by screws. The part of the second damping elastic member 14 connected to the sling 15 is slidably connected between the inner wall of the protective box 10 and the frame 1, so that the end of the second damping elastic member 14 can slide along the axial direction, which plays a guiding role for the end of the second damping elastic member 14.

[0037] Example 2

[0038] A flexible support includes at least two opposing frames 1, with a rotating frame 2 rotatably connected between the two frames 1. A slider 5 is rotatably connected to the middle of the frame 1. Slide grooves 4 are provided on both sides of the rotating frame 2. The slider 5 is slidably connected in the slide grooves 4. A first damping elastic element 6 is provided between both ends of the slider 5 and the inner wall of the slide groove 4. Specifically, the first damping elastic element 6 and the second damping elastic element 14 are both damping springs. The rotating frame 2 is inclined between the two frames 1, and its top and bottom ends are respectively connected to the frame 1 by suspension cables 15.

[0039] Please see Figure 2-4 Both the top and bottom of the rotating frame 2 are fixedly connected to wind deflectors 7. The wind deflector 7 at the top of the rotating frame 2 is set on the top surface of the rotating frame 2, and the wind deflector 7 at the bottom of the rotating frame 2 is set on the bottom surface of the rotating frame 2. When the wind deflector 7 is subjected to airflow, it can make the rotating frame 2 rotate quickly in a preset direction to adjust the angle, so as to avoid the rotating frame 2 rotating uncontrollably under the action of airflow. The middle part of the wind deflector 7 is provided with a vent 8 for ventilation. When the airflow speed is too fast, the vent 8 is used to reduce the wind resistance of the wind deflector 7, so as to avoid the frame 1 being subjected to excessive external force due to the setting of the wind deflector 7.

[0040] Example 3

[0041] A flexible stent, such as Figure 1-7 As shown, based on Embodiment 2, the difference from Embodiment 2 is that there are a total of three frames 1, and two rotating frames 2 are rotatably connected between the three frames 1. According to the design requirements, the required number of frames 1 can be added between the frames 1 on both sides. The number of frames 1 is always one more than the number of rotating frames 2. The middle part of the middle frame 1 is rotatably connected to the frames 1 on both sides, and fixed platforms 13 are fixedly connected to both sides of the top. Except for the frames 1 on both sides, the other frames 1 are provided with sliders 5, fixed pulleys 11 and fixed platforms 13 on both sides, and the two ends of the fixed platforms 13 are also connected to the second damping elastic members 14.

[0042] The working principle of this invention is as follows: In severe weather with strong airflow, when the front of the photovoltaic panel body 3 faces the wind, the airflow moves upward along the front of the photovoltaic panel body 3. The wind deflector 7 at the top of the rotating frame 2 blocks part of the airflow, causing the top of the rotating frame 2 to press down and the bottom to lift up. At the same time, the slider 5 slides downward relative to the slide groove 4, compressing the first damping elastic element 6 in the slide groove 4. Meanwhile, the suspension cable 15 connected to the top of the rotating frame 2 is stretched, which in turn pulls the second damping elastic element 14. As the top of the rotating frame 2 rotates downward, the rotating shaft moves forward, reducing the windward area of ​​the rotating frame 2 and preventing the rotating frame 2 from rotating uncontrollably. The first damping elastic element 6 and the second damping elastic element 14 will play a buffering role when compressed or stretched, effectively preventing the suspension cable 15 from breaking.
