[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, please refer to Figure 1 - Figure 5 , a folding solar photovoltaic power generation device with ventilation and heat - dissipation functions, including: Box body 1, inside which a partition board 10 is fixedly connected. There are two partition boards 10 in total. A base 9 is fixedly connected between the two partition boards 10. A lower photovoltaic panel 2 is slidably connected inside the base 9. The top end of the lower photovoltaic panel 2 is fixedly connected with a handle 4. A positioning block 8 is fixed between the two partition boards 10; The upper photovoltaic panel 3 is fixedly connected with two connecting plates 11 at the bottom. Both sides of the two connecting plates 11 are hinged with vertical support rods 12 and L-shaped support rods 13. The bottoms of the two vertical support rods 12 and the two L-shaped support rods 13 are hinged on the sides of the two partition plates 10. On the inner and outer sides of the hinge joints between the two vertical support rods 12 and the partition plates 10, a first worm gear 503 and a first intermediate gear 504 are respectively fixed. The L-shaped part of the L-shaped support rod 13 is below the partition plate 10, which can support the upper photovoltaic panel 3 and reduce part of the weight of the rotating support rod 507. On the inner and outer sides of the hinge joints between the two L-shaped support rods 13 and the partition plates 10, a second intermediate gear 506 and a second worm gear 505 are respectively fixed. Cavities 502 are provided on both sides of the lower photovoltaic panel 2. Tooth segments 501 are assembled in the two cavities 502. During the process of the lower photovoltaic panel 2 moving outwards, the cavities 502 on both sides move along with the lower photovoltaic panel 2, and the tooth segments 501 cause the first intermediate gear 504 and the second intermediate gear 506 to rotate, thereby driving the vertical support rod 12 and the L-shaped support rod 13 to perform circular motion in the direction opposite to that of the lower photovoltaic panel 2. The first intermediate gear 504 drives the roller 512 on its outer side to rotate synchronously. The rotating support rod 507 can contact the ground, share the weight of the upper photovoltaic panel 3, and provide support, improving the stability of the upper photovoltaic panel 3; Large gears 509 are fixedly connected to the outer sides of the two connecting plates 11. The two large gears 509 are in transmission connection with the rotating support rod 507 through transmission components. The transmission components include large gears 509, large gears 511, rollers 512, belts 510, and small gears 513. Rollers 512 are fixedly connected to the sides of the two large gears 509 and the two large gears 511. Belts 510 are assembled between every two rollers 512. Small gears 513 are meshed above the two large gears 511. Rotating support rods 507 are fixedly connected to the outer sides of the two small gears 513. The belt 510 assembled on the roller 512 rotates, driving the subsequent roller 512 to rotate, causing the second intermediate gear 506 to rotate, and the second intermediate gear 506 drives the meshed small gear 513 to rotate. The small gear 513 is fixedly connected to the rotating support rod 507, and the small gear 513 can drive the rotating support rod 507 to rotate and unfold. The belt 510 for transmitting power has the advantages of high efficiency and quietness. Grooves 508 are provided on the left and right sides of the upper photovoltaic panel 3. The rotating support rod 507 can be retracted into the grooves 508, ensuring the portability of the box body 1 and also avoiding damage to the rotating support rod 507.

[0019] During use, for the foldable solar photovoltaic power generation device with ventilation and heat dissipation functions, when in the folded state, manual effort is required to pull the lower photovoltaic panel 2 outward from the side through the handle 4, causing the lower photovoltaic panel 2 to move horizontally. During the outward movement of the lower photovoltaic panel 2, the cavities 502 on both sides move along with the lower photovoltaic panel 2. Since the teeth 501 are fixedly connected to the bottom of the cavities 502, the teeth 501 also move outward. During the outward movement, the medium gear one 504 and the medium gear two 506 located at the hinge of the vertical support rod 12 and the L-shaped support rod 13 at the partition plate 10 are inside the cavities 502 and are tightly engaged with the teeth 501 before being pulled. When the lower photovoltaic panel 2 moves outward, the teeth 501 cause the medium gear one 504 and the medium gear two 506 to rotate, thereby driving the vertical support rod 12 and the L-shaped support rod 13 to perform circular motion in the direction opposite to the lower photovoltaic panel 2. During the outward circular motion of the upper photovoltaic panel 3, at the hinge at the top of the L-shaped support rod 13, the large gear one 509 located outside the connecting plate 11 rotates synchronously during the rotation process. The large gear one 509 drives the roller 512 outside it to rotate synchronously. The belt 510 assembled on the roller 512 rotates, driving the roller 512 behind to rotate, causing the large gear two 511 to rotate. The large gear two 511 meshes with the small gear 513, causing the large gear two 511 to drive the engaged small gear 513 to rotate. The small gear 513 is fixedly connected to the rotating support rod 507, and the small gear 513 can drive the rotating support rod 507 to rotate and unfold. The rotating support rod 507 can contact the ground to share the weight of the upper photovoltaic panel 3 for support, improving the stability of the upper photovoltaic panel 3. At the same time, only by pulling the lower photovoltaic panel 2, the upper photovoltaic panel 3 and the rotating support rod 507 can be unfolded synchronously, improving the folding convenience.

[0020] Example 2, please refer to Figure 1 - Figure 6The two worm gears 503 and 505 are meshed with worms 606 at the bottom. The two worm gears can generate greater force, so that the pin 601 can penetrate deeper into the soil, making the box body 1 more stable and not accidentally overturned. The two partition plates 10 are fixedly connected to the outside with brackets 604. The brackets 604 are on each worm 606. There are two of them, which are equal in size and shape, for a total of four. The ends of the two worm gears 606 are fixedly connected to the cross plates 607. The front and rear outer sides of the two partition plates 10 are opened. There are slide grooves 609, and the tops of the four slide grooves 609 are fixedly connected to the top plates 605, and the bottoms of the four top plates 605 are fixedly connected to the springs 603. When the cross plate 607 rotates in the opposite direction, the springs 603 can rely on the elastic force to move the two T-shaped vertical slides 602 and the two T-shaped rack slides 608 upward to the initial position, and the two front end slide grooves 609 are slidably connected to the T-shaped vertical slides 602, and the two rear end slide grooves 609 are slidably connected to the T-shaped rack slides 608, and the two T-shaped vertical slides 602 are slidably connected to the T-shaped rack slides 608. 02 and the lower part of the two T-shaped rack slides 608 are fixedly connected with a pin 601, and the worm gear 1 503 and the worm gear 2 505 rotate to make the meshing worm 606 rotate, and there are horizontal plates 607 at the ends of the worm 606, which will rotate while making the horizontal plates 607 rotate, and the rotating horizontal plates 607 will press against the protruding parts of the T-shaped vertical slide 602 and the T-shaped rack slide 608, so that the entire T-shaped vertical slide 602 and the T-shaped rack slide 608 are lowered, so that the T-shaped vertical slide 602 and the T-shaped rack slide 608 are lifted. The pins 601 fixed under the strip slide 608 will extend out of the box body 1 and be firmly inserted into the soil under the box body 1. There are three pins 601 under the two T-shaped vertical slides 602 and the two T-shaped rack slides 608, totaling twelve pins, which are arranged vertically. Multiple pins 601 can make the box body 1 inserted tighter, improving the stability of the box body 1. At the same time, the pins 601 can be recovered into the box body 1 at any time, which improves the portability of the box body 1 and can also prevent sharp spikes from hurting people and causing unnecessary casualties.

[0021] In use, on the basis of the first embodiment, while pulling the lower photovoltaic panel 2, the applied force causes the medium gear 1 504 and the medium gear 2 506 to rotate, and the worm gear 1 503 and the worm gear 2 505 rotate accordingly, causing the engaged worm 606 to rotate. There are cross plates 607 at both ends of the worm 606, and the cross plates 607 will rotate during rotation. The rotating cross plates 607 were parallel to the protruding parts of the T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608 before. When the cross plates 607 rotate, they will resist the protruding parts of the T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608, causing the entire T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608 to descend. As a result, the pins 601 fixed below the T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608 will protrude from the box body 1 and firmly insert into the soil below the box body 1, making the entire box body 1 more stable. When recycling, the worm gear 1 503 and the worm gear 2 505 rotate in the opposite direction, causing the worm 606 to rotate in the opposite direction. The cross plates 607 at the ends of the worm 606 return to the initial state, and the entire T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608 will be pulled back to the initial state under the action of the spring 603 above. In this way, the fixing method of the entire box body 1 is stable. At the same time, the box body 1 is a cube when recycled, which can be transported and moved more conveniently.

[0022] Embodiment 3, please refer to Figure 1 - Figure 8, on the basis of the first and second embodiments, external heat dissipation holes 701 are provided on both sides of the box body 1, external heat dissipation holes 701 are provided on the partition plate 10, and large diversion holes 705 are provided at the opposite ends of the handle 4. Wind enters from the external heat dissipation holes 701 and blows inside. Since the front is closed, the wind will pass through above the lower photovoltaic panel 2 or blow into the internal heat dissipation holes 707, pass through the intervals inside the partition plate 10 and the box body 1, and finally blow out from the external heat dissipation holes 701, forming an air duct to fully dissipate heat from the entire box body 1. A wind collecting cover 704 is fixedly connected to the outer periphery of the large diversion hole 705. There are two wind collecting covers 704, arranged symmetrically left and right, which can collect wind into the large diversion hole 705. A baffle 703 is assembled below the inner side of the large diversion hole 705. Medium gears three 702 are fixedly connected to the left and right sides of the baffle 703. The medium gears three 702 are engaged with the T-shaped rack slide plate 608 on the right side. Shading hole plates 706 are fixedly connected to the left and right sides of the upper photovoltaic panel 3. A baffle groove 708 is provided at the end of the lower photovoltaic panel 2 away from the handle 4. The upper photovoltaic panel 3 moves upward, so that the shading hole plates 706 fixedly connected to both sides below the upper photovoltaic panel 3 rise, enabling the external heat dissipation holes 701 on the box body 1 to achieve through-flow. The T-shaped rack slide plate 608 moves downward, causing the medium gears three 702 engaged with the T-shaped rack slide plate 608 to rotate. The rotation of the medium gears three 702 drives the baffle 703 to move downward, opening the large diversion hole 705 and realizing an air duct to improve the heat dissipation efficiency. A total of thirty-six external heat dissipation holes 701 are provided in the external heat dissipation holes 701 of the box body 1, and internal heat dissipation holes 707 are provided in the two partition plates 10, with a total of eleven internal heat dissipation holes 707. This prevents dust from entering through the heat dissipation holes when the device is not in use and improves the heat dissipation efficiency.

[0023] In use, on the basis of the first and second embodiments, first place the box body 1 with the position of the large diversion hole 705 facing the direction from which the wind blows. In this way, an air duct will be formed inside the box body 1, and the lower photovoltaic panel 2 will move outward, causing the vertical support rod 12 and the L-shaped support rod 13 to rotate, and the upper photovoltaic panel 3 to move upward. As a result, the shielding plates 706 fixedly connected to both sides below the upper photovoltaic panel 3 will rise, enabling the external heat dissipation holes 701 on the box body 1 to achieve through-flow. At the same time, as the worm 606 rotates, the T-shaped rack slide 608 moves downward, causing the medium gear three 702 engaged with the T-shaped rack slide 608 to rotate. The rotation of the medium gear three 702 drives the shielding plate 703 to move downward, opening the large diversion hole 705. The air collecting hood 704 outside the large diversion hole 705 can also collect more wind, forming an air duct. The wind enters from the large diversion hole 705 and exits from the internal heat dissipation hole 707 and the external heat dissipation hole 701, which can better relieve the heat generated by the photovoltaic panel during operation. When retracting, the shielding plate 703 moves downward, the upper photovoltaic panel 3 retracts into the box body 1, blocking the external heat dissipation hole 701. The medium gear three 702 rotates, causing the shielding plate 703 to move upward, blocking the large diversion hole 705. The lower part of the shielding plate 703 will also be stuck into the shielding plate groove 708, preventing dust from entering due to the open state of the external heat dissipation hole 701 and the large diversion hole 705 when the device is idle, thus damaging the internal components, and at the same time improving the heat dissipation efficiency.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
