[0031] In addition, the device mainly uses an auxiliary positioning mechanism 2 to assist in positioning the solar photovoltaic panel 1, ensuring the stability and flexibility of the photovoltaic panel when installed outside the balcony. Each set of auxiliary positioning mechanisms 2 includes a dual-axis adjustment part 21 and a dual-axis adjustment part 22, which are connected by a U-shaped clamp segment 1 24 and a U-shaped clamp segment 2 25, and are provided with support and angle adjustment capabilities by a supporting torsion spring member 26.

The distance between two adjacent arc-shaped extension parts 213 is smaller than the diameter of the supporting ball 214, which is used to prevent the supporting ball 214 from falling off the annular aperture formed by the plurality of arc-shaped extension parts 213. A sliding ring 215 is fixedly installed at one end of the arc-shaped extension part 213, and the sliding ring 215 is slidably connected to the outer wall of the dual-axis adjustment part 22; liquid storage cotton rings 216 are sleeved at both ends of the dual-axis adjustment part 21 and the dual-axis adjustment part 22 to prevent hand sweat during the adjustment process;

[0035] The rubber connecting tube 212 is fixed at the middle of multiple arc-shaped limit bolts 23, passing through adjacent arc-shaped limit bolts 23 to maintain a fixed spacing between them. The arc-shaped extension part 213 is fixed at both ends of the arc-shaped limit bolts 23 to form an annular aperture, in which multiple support balls 214 are placed to prevent them from falling off. The sliding ring 215 is fixed at one end of the arc-shaped extension part 213 and is slidably connected to the outer wall of the dual-axis adjustment part 22 to ensure its flexible adjustment. The liquid storage cotton ring 216 is sleeved on both ends of the dual-axis adjustment part 1 21 and the dual-axis adjustment part 22 to increase the stability and consistency of the overall structure. This design enables the photovoltaic panel to be stable while achieving multi-angle and flexible adjustment.

[0036] A positioning plate 217 is installed at one end of the central positioning shaft 28 near the dual-axis adjustment part 21 by bolts, and a non-slip rubber ring 218 is fixedly installed on one side of the positioning plate 217; an extension slip ring 219 is fixedly installed at one end of the rubber connecting tube 212, and a plurality of support balls 220 are placed on the inner wall of the rubber connecting tube 212.

[0037] It should be noted that in actual use, one end of the auxiliary positioning mechanism 2 is pre-installed on the periphery of the balcony of the resident. Since the solar photovoltaic panel 1 is positioned outside the balcony, it is not conducive to adjusting the angle in mid-air, resulting in a large number of installation and disassembly times, and outdoor debugging is very cumbersome. This solution pre-positions the solar photovoltaic panel 1 through four auxiliary positioning mechanisms 2, and the auxiliary positioning mechanism 2 is positioned by bolt positioning. After the angle adjustment of the solar photovoltaic panel 1 is completed, it is fixed for the second time. The auxiliary positioning mechanism 2 can be removed or not according to actual needs. This design not only simplifies the installation steps, but also greatly reduces the time and labor costs required for adjusting the angle and position. It is especially suitable for the complex environment of high-rise building balconies. The pre-positioning design takes into account the diversity of different balcony structures and ensures the wide applicability of the device.

[0038] The positioning suction cup 211 is pre-positioned by a suction cup, which has no bearing capacity and is only used as a positioning position. A bolt penetrates the flat support base 221 or the buffer part 222 to fix one end of the auxiliary positioning mechanism 2. The positioning plate 217 and the anti-skid rubber ring 218 at the other end are pre-fixed at the position of the solar photovoltaic panel 1 by bolts. This pre-positioning design makes the entire installation process more accurate and efficient, avoiding the trouble caused by repeated adjustments. The use of the suction cup also provides a convenient temporary fixing method, which makes the user more flexible in the initial adjustment and can quickly determine the best installation position. In addition, the suction cup positioning also reduces the damage to the balcony structure and protects the integrity of the building.

[0039] When adjusting the angle, the deformation of the supporting torsion spring 26 forms the angle adjustment function, wherein the main functions of the supporting ball 220 and the supporting ball 1 214 are to provide multi-directional support and stability, ensuring that the solar photovoltaic panel 1 is both flexible and stable during installation and adjustment. Through this multi-point support design, it is possible to effectively cope with changes in the external environment, especially in the case of strong winds, to ensure that the solar photovoltaic panel 1 is not easy to shake or shift. The supporting ball not only provides mechanical support, but also absorbs part of the external force impact to protect the structural integrity of the entire device. This design takes into account various possibilities in actual use, including stability under extreme weather conditions, and improves the durability and reliability of the device.

[0040] In addition, the electric telescopic part 29 is used for lateral angle adjustment, the arc-shaped limit bolt 23 is used for holding and lateral movement, and the supporting torsion spring part 26 cooperates to form universal movement. Through the cooperation of the auxiliary positioning mechanism 2 and the electric telescopic part 29, not only the installation efficiency of the solar photovoltaic panel 1 is improved, but also its adaptability at different angles and heights is enhanced, so that it can better absorb solar energy and improve the overall power generation efficiency. The universal movement design allows the solar photovoltaic panel 1 to be fine-tuned in multiple dimensions to ensure the best lighting angle, thereby maximizing the power output. By optimizing the adjustment mechanism, the solar photovoltaic panel 1 can always maintain the best angle in different seasons and different time periods, thereby improving the energy utilization efficiency of the overall system.

[0041] This design also takes into account the maintenance and adjustment needs in actual use. By simplifying the disassembly and assembly process, users can clean, repair and adjust the solar photovoltaic panel 1 more conveniently, thereby extending the service life of the solar photovoltaic panel 1 and ensuring its stability and efficiency in long-term use. Considering the complexity in actual operation, the entire device adopts a modular design. Users can replace or maintain a certain module separately as needed without having to disassemble the entire device, which greatly improves maintenance efficiency and economy. The modular design also makes future upgrades and improvements more convenient. Users can continuously optimize the photovoltaic system according to technological progress to maintain its advancement and efficiency.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
