Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation system. Background Technology

[0002] Photovoltaic power generation is a technology that uses solar cells to convert sunlight into electrical energy. The core principle is the photovoltaic effect, where photons excite electrons to form an electric current. When sunlight shines on a solar cell, the photon energy is absorbed by the semiconductor material, causing electrons to be excited from covalent bonds and forming electron-hole pairs. These electrons and holes are separated under the influence of the electric field inside the semiconductor and form a current in the external circuit, thus converting light energy into electrical energy.

[0003] Chinese Patent Application No. 2022225090026 discloses a photovoltaic power generation device, including a solar panel, a support plate, an adjusting plate, a connecting beam, a support column, and a base. The solar panel is rotatably connected to the support plate, which has an adjusting groove. The adjusting plate is installed within the adjusting groove and can slide along it. One end of the connecting beam is rotatably connected to the back of the solar panel, and the other end is rotatably connected to the adjusting plate. The support column is located on the side of the support plate facing away from the connecting beam and is perpendicularly connected to the support plate. The base has an annular groove, and the support column is installed within it and can slide along it to rotate the support plate relative to the base. When the adjusting plate slides along the adjusting groove, it moves the connecting beam, thereby causing the solar panel to rotate relative to the support plate.

[0004] The aforementioned photovoltaic power generation device is fixed on a base, making it difficult to move and inconvenient to transport. Therefore, we propose a foldable photovoltaic power generation system that is easy to transport. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a photovoltaic power generation system. The system involves driving the photovoltaic module to rotate around a rotating rod, adjusting the angle of the photovoltaic panel to make it vertically downwards, loosening the first bolt, and then moving the sliding seat to one end of the moving frame. Next, the second bolt is removed to move it away from the third threaded hole. Then, the U-shaped frame is rotated and placed in a horizontal position. The photovoltaic power generation mechanism is then folded onto the moving frame, reducing the volume of the photovoltaic power generation system and facilitating its transport to a suitable location for photovoltaic power generation.

A second bolt 407 is provided in the second through hole 4061 and threadedly connected to the third threaded hole 3011.

[0037] In this embodiment, the photovoltaic module 31 is driven to rotate around the rotating rod a303, and the angle of the photovoltaic panel 312 is adjusted so that it is vertically downward. At this time, the first bolt 405 is loosened, and the sliding seat 401 is moved to one end of the moving frame 1. Then, the second bolt 407 is removed so that it leaves the third threaded hole 3011. Then, the U-shaped frame 301 is rotated and placed in a horizontal state. At this time, the photovoltaic power generation mechanism 3 is folded on the moving frame 1, which reduces the volume of the photovoltaic power generation system and makes it easier to transport the photovoltaic power generation system to a suitable location for photovoltaic power generation.

[0039] Move the sliding seat 401 to adjust the position of the photovoltaic power generation mechanism 3 on the moving frame 1. By moving the photovoltaic power generation mechanism 3 to a suitable position, tighten the first bolt 405 to fix the sliding seat 401 on the moving frame 1, thereby fixing the photovoltaic power generation mechanism 3 on the moving frame 1.

[0040] Example 2: Figures 1-8 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0041] The photovoltaic module 31 includes an outer frame 311, a photovoltaic panel 312 is installed inside the outer frame 311, and a second T-shaped groove 3111 is opened on the outer side of the outer frame 311.

[0044] In this embodiment, the initial state is as follows: Figure 1 As shown, the photovoltaic panel 312 absorbs sunlight and converts solar energy into electrical energy. Moving the moving frame 1 orients the photovoltaic panel 312 toward the direction of sunlight, while simultaneously loosening the nut 325 with a wrench, the moving mounting sleeve 323 is moved, and the screw 322 slides in the arc groove 3021. The second T-shaped block 321 slides in the second T-shaped groove 3111, driving the photovoltaic module 31 to rotate around the rotating rod a303. The angle of the photovoltaic panel 312 is adjusted as needed. Tightening the nut 325 with a wrench drives the nut 325 to press against the fixed seat 302, limiting the photovoltaic module 31. At this time, the angle of the photovoltaic module 31 is constant, preventing the photovoltaic module 31 from rotating.

[0045] Work steps

[0046] Step 1, Angle Adjustment: Initial state as follows Figure 1As shown, the photovoltaic panel 312 absorbs sunlight and converts solar energy into electrical energy. Moving the movable frame 1 orients the photovoltaic panel 312 towards the sunlight, while simultaneously loosening the nut 325 with a wrench. At this time, the movable mounting sleeve 323 moves, and the screw 322 slides within the arc-shaped groove 3021. The second T-shaped block 321 slides within the second T-shaped groove 3111, driving the photovoltaic module 31 to rotate around the rotating rod a303. The angle of the photovoltaic panel 312 can be adjusted as needed. Tightening the nut 325 with a wrench causes the nut 325 to press against the fixed base 302, limiting the position of the photovoltaic module 31. At this time, the angle of the photovoltaic module 31 remains constant, preventing rotation of the photovoltaic module 31.

[0047] Step 2, Folding process: Drive the photovoltaic module 31 to rotate around the rotating rod a303, adjust the angle of the photovoltaic panel 312 to make it vertical and downward, at this time loosen the first bolt 405, then move the sliding seat 401 to move it to one end of the moving frame 1, then remove the second bolt 407 to make it leave the third threaded hole 3011, then rotate the U-shaped frame 301 and place the U-shaped frame 301 in a horizontal state. At this time, the photovoltaic power generation mechanism 3 is folded on the moving frame 1, which reduces the volume of the photovoltaic power generation system and makes it easier to transport the photovoltaic power generation system to a suitable location for photovoltaic power generation.

[0048] When needed, the photovoltaic power generation mechanism 3 is rotated to a vertical position, the third threaded hole 3011 corresponds to the second through hole 4061, the second bolt 407 passes through the second through hole 4061 and is threadedly connected to the third threaded hole 3011 to limit the U-shaped frame 301.

[0049] Move the sliding seat 401 to adjust the position of the photovoltaic power generation mechanism 3 on the moving frame 1. By moving the photovoltaic power generation mechanism 3 to a suitable position, tighten the first bolt 405 to fix the sliding seat 401 on the moving frame 1, thereby fixing the photovoltaic power generation mechanism 3 on the moving frame 1.
