[0002] Solar energy is one of the important new energy sources developed by countries around the world to cope with the energy crisis. Solar energy refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. In modern times, it is generally used to generate electricity or provide energy for water heaters. Solar cells are also called "solar chips" or "photovoltaic cells". They are a type of optoelectronic semiconductor wafer that uses sunlight to directly generate electricity. When using solar panels, the angle needs to be adjusted according to changes in sunlight to achieve the best light reception effect and improve power generation efficiency.

[0032] See also Figure 1-Figure 8The folding mechanism 9 shown in the figure includes a lifting block 10 that is slidably connected to the inner wall of the support tube 2. The upper side of the lifting block 10 in the support tube 2 is used to store liquid. The folding mechanism 9 is used to control the height of the lifting block 10, so that the liquid pressure in the support tube 2 changes, driving the second photovoltaic panel 6 and the third photovoltaic panel 7 to rotate and open and close. The control mechanism 11 is installed on the base 1, and is used to release the connection between the rotating member 8 and the support tube 2 when the second photovoltaic panel 6 and the third photovoltaic panel 7 are in a folded state, so that the support tube 2 can automatically change its direction due to wind, thereby reducing wind resistance and making full use of the surrounding light energy.

[0033] See also Figure 3-Figure 6 The folding mechanism 9 shown in the figure also includes three groups of first fixing buckles 12 fixedly installed on the second photovoltaic panel 6 and the third photovoltaic panel 7 respectively, and the three groups of first fixing buckles 12 are rotatably connected to the sliding rods 13 respectively, and three groups of second fixing buckles 14 are fixedly connected to the mounting block 3. The outer wall of the sliding rod 13 is movably sleeved with a sleeve tube 15, and the sleeve tube 15 is connected to a rotating tube 16 rotatably connected to the second fixing buckle 14. The support tube 2 is connected to a connecting tube 17 connected to the rotating tube 16, and the support tube 2 is provided with a control member 18 for controlling the sliding state of the lifting block 10 according to the wind force.

[0034] In this embodiment, when the external wind force is small, by controlling the lifting block 10 to move upward, the liquid in the support tube 2 is pushed upward into the connecting tube 17, and is input into the sleeve tube 15 through the rotating tube 16, thereby pushing the sliding rod 13 to move, and the sliding rod 13 pushes the second photovoltaic panels 6 on both sides and the third photovoltaic panel 7 on the upper side to flip around the hinge to a position flush with the first photovoltaic panel 5, so that the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 form a large solar energy receiving surface (such as Figure 2 ), fully receiving the irradiation of light to achieve the purpose of charging and energy storage. When the sleeve tube 15 rotates, the top ends of the rotating tube 16 and the connecting tube 17 rotate with each other and always remain connected.

[0035] When the wind force is greater than the set value, the control member 18 controls the lifting block 10 to move downward, and the liquid in the sleeve tube 15 is pumped into the support tube 2 through the rotating tube 16 and the connecting tube 17, thereby driving the sliding rod 13 to slide toward the inside of the sleeve tube 15, pulling the second photovoltaic panel 6 and the third photovoltaic panel 7 to flip and fold, so that the side edges of the two groups of second photovoltaic panels 6 and the edges of the third photovoltaic panel 7 fit each other (such as Figure 1), and at the same time, the connection drive of the support tube 2 is released through the control mechanism 11, so that the support tube 2 can rotate freely under the wind force. At this time, the wind force blows to rotate the first photovoltaic panel 5. Since the position where the two groups of second photovoltaic panels 6 and the third photovoltaic panel 7 are attached is conical, the wind resistance is small, and the wind will blow the whole to rotate the support tube 2, always ensuring that the tip of the cone is facing the direction of the wind. This process does not require motor control, which saves energy while effectively reducing the influence of wind resistance. At the same time, the frame structure composed of the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 can effectively utilize the surrounding light, greatly improving the utilization rate of light energy in the folded state.

[0036] Example 2

[0037] See also Figure 1-Figure 12 Embodiment 2 is described. This embodiment further describes embodiment 1. The control member 18 shown in the figure includes multiple groups of first rotating rods 21 rotatably connected to the rotating disk 19. The outer wall of the support tube 2 is evenly rotatably connected to multiple groups of second rotating rods 22. The first rotating rod 21 is slidably connected to the second rotating rod 22. A pressure sensor 23 for sensing the thrust of the second rotating rod 22 is fixedly connected to the first rotating rod 21. A lifting member 24 for controlling the lifting state of the lifting block 10 is provided in the base 1. The lifting member 24 includes an electric telescopic rod 36 fixedly installed in the base 1. The telescopic end of the electric telescopic rod 36 is fixedly connected to a lifting rod 37. The upper end of the lifting rod 37 is rotatably connected to the lifting block 10 through a rotating buckle. The lifting rod 37 is used to drive the lifting block 10 to move up and down.

[0038] See also Figure 2-Figure 12 The rotating member 8 shown in the figure includes a plurality of fixed shafts 25 uniformly fixedly mounted on the rotating ring 20, and a ratchet 26 is rotatably connected to the fixed shaft 25. A driving motor 27 is fixedly connected inside the base 1, and the driving motor 27 is preferably of model YYHS-40. A gear 28 capable of meshing with the ratchet 26 is coaxially fixedly connected to the output end of the driving motor 27. The control mechanism 11 is used to control the rotation state of the ratchet 26. The rotating member 8 also includes a light sensor 38 fixedly mounted on the third photovoltaic panel 7. The light sensor 38 is used to sense the light intensity and control the driving motor 27 to rotate, so that the first photovoltaic panel 5 rotates toward the direction with the strongest light.

[0039] In this embodiment, the lifting and lowering of the lifting rod 37 is controlled by the electric telescopic rod 36, so that the lifting block 10 is lifted and lowered. When the wind force is small, the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 are subjected to small thrust by the wind, and the support tube 2 has relatively uniform thrust on the second rotating rod 22 on all sides. The pressure sensor 23 is subjected to small thrust, and the electric telescopic rod 36 is controlled to move the lifting block 10 upward, and the control mechanism 11 makes the ratchet 26 swing and engage to one side of the gear 28, and the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 are unfolded, and the light sensor 38 senses the light intensity, and the gear 28 is driven to rotate by the drive motor 27, thereby driving the ratchet 26 to drive the rotating ring 20 and the rotating disk 19 to rotate, and the rotating disk 19 drives the support tube 2 and the mounting block 3 to rotate, thereby adjusting the direction of the first photovoltaic panel 5 and improving the light energy receiving efficiency.

[0040] When the wind force is greater than the set value, the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 are pushed by the unilateral wind force, causing the support tube 2 to slightly deviate in the direction of the wind. At this time, the second rotating rod 22 on this side slides a longer distance in the first rotating rod 21, and the thrust on the pressure sensor 23 is greater than the set value, thereby controlling the electric telescopic rod 36 to pull down the lifting block 10 through the control program, driving the second photovoltaic panel 6 and the third photovoltaic panel 7 to flip and fold. When the lifting block 10 moves down to the set position, the control mechanism 11 drives the ratchet 26 to rotate to the side away from the gear 28, releasing the connection between the gear 28 and the ratchet 26. Thereafter, the rotation of the rotating ring 20 and the support tube 2 is not mechanically driven, and the positions of the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7 can be automatically adjusted according to the wind direction, which saves energy while effectively reducing the influence of wind resistance, making the equipment run more stably and greatly extending the service life of the equipment.

[0041] Example 3

[0042] See also Figure 7-Figure 12 Embodiment 3 is described. This embodiment further describes Embodiment 1. The control mechanism 11 shown in the figure includes a bellows 29 fixedly mounted on the bottom of the lifting block 10. The bottom end of the bellows 29 is fixedly connected to the bottom of the support tube 2. A storage chamber 30 is provided in the rotating disk 19. The bottom of the bellows 29 is connected to a delivery pipe 31 that is connected to the storage chamber 30. A swinging member 32 is provided in the rotating disk 19 for controlling the swinging state of the ratchet 26 according to the air pressure in the storage chamber 30.

[0043] See also Figure 7-Figure 12 The swinging member 32 shown in the figure includes a connecting shaft 33 fixedly mounted on the ratchet 26, and an arc rod 34 is fixedly connected to the connecting shaft 33. A plurality of arc grooves 35 connected to the storage chamber 30 are provided in the rotating disk 19, and the arc rod 34 is slidably connected to the inner wall of the arc groove 35.

[0044] In this embodiment, when the lifting block 10 moves upward, it will drive the upper side of the bellows 29 to pull upward, so that the gas in the storage chamber 30 is sucked into the bellows 29, so that the air pressure in the storage chamber 30 is reduced, and the arc rod 34 is pulled to slide into the arc groove 35, so that the ratchet 26 can rotate to one side of the gear 28. At this time, when the gear 28 rotates unidirectionally, it can drive the ratchet 26 to drive the rotating ring 20 to rotate. When the lifting block 10 moves downward, the bellows 29 is compressed downward, and the gas is filled into the storage chamber 30 through the delivery pipe 31, so that the air pressure in the arc groove 35 increases, and the arc The shaped rod 34 is pushed out in all directions, thereby driving the ratchet 26 to rotate around the fixed axis 25 through the connecting shaft 33, and the ratchet 26 rotates to the side away from the gear 28 to release the meshing with the gear 28. After that, the rotation of the support tube 2 will cause the rotating disk 19 to rotate together with the rotating ring 20 on the base 1, and will not drive the rotation of the lifting rod 37, the electric telescopic rod 36 and the gear 28, thereby reducing the resistance to the rotation of the support tube 2 to the greatest extent, making it possible to more sensitively sense the wind direction and switch the orientation of the first photovoltaic panel 5, the second photovoltaic panel 6 and the third photovoltaic panel 7, thereby reducing the impact of wind resistance on the equipment.
