Second, the traditional rigidly expanded photovoltaic panel has structural safety hazards under extreme weather conditions, such as fatigue damage of support structure caused by aerodynamic load generated by strong wind, and stress concentration on the surface of the component and decrease of light transmittance caused by snow accumulation, which seriously affects the service life and operation safety of the equipment.

[0037] The utility model will be further explained in detail in combination with the drawings.

[0038] A double-sided power generation single-wave photovoltaic assembly, comprising a T-shaped support 2. The photovoltaic panel 1 is swingably arranged at the upper end of the support 2. In specific implementation, the upper end of the support 2 is provided with two swingable photovoltaic panels 1, and the two photovoltaic panels 1 are respectively located at the two sides of the support 2. The two photovoltaic panels 1 can swing independently. When the two photovoltaic panels 1 are retracted, the two photovoltaic panels 1 can be A-shaped and attached to the two sides of the support 2.

[0039] The swing frame 4 is swingably arranged at the middle part of the support 2. The electric cylinder 5 connects the swing frame 4 and the support 2, and the two ends of the electric cylinder 5 are respectively hinged to the swing frame 4 and the support 2. The electric cylinder 5, the swing frame 4 and the support 2 form a triangular linkage structure. The support assembly 3 connects the swing frame 4 and the photovoltaic panel 1, and the two ends of the support assembly 3 are respectively hinged to the swing frame 4 and the photovoltaic panel 1. The support assembly 3, the swing frame 4, the photovoltaic panel 1 and the support 2 form a quadrilateral linkage structure. Thus, the photovoltaic panel 1 has a larger swing range.

[0040] Through the above structure, the swing frame 4 driven by the electric cylinder 5 cooperates with the support assembly 3 to adjust the inclination angle of the photovoltaic panel 1, real-time tracks the sun azimuth, maintains the best light receiving angle, and thus maximizes the power generation efficiency.

[0041] ​The specific structure of the support assembly 3 comprises a first support rod 301 and a second support rod 307. The first support rod 301 is hinged with the swing frame 4, and the second support rod 307 is hinged with the photovoltaic panel 1. A guide column 302 is arranged on the first support rod 301. A guide seat 304 is arranged on the second support rod 307, the guide column 302 is inserted into the guide seat 304 and is in sliding connection with the guide seat 304. A spring 303 is sleeved on the outer periphery of the guide column 302, and two ends of the spring 303 are fixedly connected with the first support rod 301 and the second support rod 307 respectively.

[0042] Through the above structure, the support assembly 3 is provided with a spring buffering mechanism. When a transient impact load is encountered, the spring buffering mechanism absorbs impact energy through elastic deformation of the spring 303, and reduces the stress peak value of the key components.

[0043] The specific structure of the support assembly 3 further comprises a detection block 305. The detection block 305 is slidably arranged in the second support rod 307, the detection block 305 is fixedly connected with the guide column 302, and the detection block 305 is fixed to the end of the guide column 302. A proximity sensor 306 is arranged on the second support rod 307, and the proximity sensor 306 can sense the detection block 305. In a specific implementation, the proximity sensor 306 is provided with two along the length direction of the second support rod 307, and the detection block 305 moves between the two proximity sensors 306. The second support rod 307 is a square tube, and the detection block 305 is square. Therefore, the detection block 305 can only slide along the length direction of the second support rod 307.

[0044] The support assembly 3 can detect the external force borne by the photovoltaic panel 1. When abnormal load caused by strong wind, snow and the like is generated, the elastic deformation of the spring 303 is too large, and the detection block 305 moves to the position of the proximity sensor 306. The proximity sensor 306 detects the detection block 305, and the system controls the electric cylinder 5 to automatically adjust the photovoltaic panel 1 to a safe storage state, effectively avoiding structural damage and ensuring the safe operation of the equipment.
