[0015] This invention provides a foldable solar photovoltaic power generation device with ventilation and heat dissipation functions. It has the following beneficial effects:

[0016] (1) This foldable solar photovoltaic power generation device with ventilation and heat dissipation function only requires the force generated when the lower photovoltaic panel is pulled by the handle to make the intermediate gear 1 and intermediate gear 2 meshed in the teeth rotate, thereby driving the vertical support rod and L-shaped support rod to move, making the intermediate gear 1 at the top of the L-shaped support rod rotate, and the roller on one side of the intermediate gear also rotates, so that the belt on the roller is transmitted to the intermediate gear 2, making the large gear drive the meshing small gear to rotate, and the rotating support rod driven by the small gear rotates, so that it contacts the ground and improves the stability of the upper photovoltaic panel. At the same time, only the lower photovoltaic panel needs to be pulled open, and the upper photovoltaic panel and the rotating support rod can be unfolded synchronously, improving the folding convenience.

[0017] (2) This foldable solar photovoltaic power generation device with ventilation and heat dissipation function, by pulling the photovoltaic by hand, the worm gear one and worm gear two fixed on the outer side of the lower end of the vertical support rod and the L-shaped support rod rotate, driving the meshing worm to rotate, so that the horizontal plates at both ends of the worm make circular motion, the horizontal plates will abut against the protruding parts of the T-shaped rack and pinion slide and the T-shaped vertical slide, so that it makes a downward motion, thereby inserting the pin installed at the bottom into the soil, fixing the entire box and preventing it from shifting due to accident.

[0018] (3) This foldable solar photovoltaic power generation device with ventilation and heat dissipation function moves the upper photovoltaic panel upward by pulling the photovoltaic panel by hand, thereby raising the shading plates on both sides below the photovoltaic panel, allowing the external heat dissipation holes on the box to flow through. At the same time, as the lower photovoltaic panel moves, the medium gear three drives the shading plate downward, opening the large guide hole. The wind collector on the outside of the large guide hole can also collect more wind, forming a wind channel, which can better alleviate the heat generated by the photovoltaic panel during operation.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1, please refer to Figure 1 - Figure 5A foldable solar photovoltaic power generation device with ventilation and heat dissipation functions, comprising:

[0033] Box 1, with partition plates 10 fixedly connected inside the box 1. There are two partition plates 10. A base 9 is fixedly connected between the two partition plates 10. A lower photovoltaic panel 2 is slidably connected inside the base 9. A handle 4 is fixedly connected to the top of the lower photovoltaic panel 2. A positioning block 8 is fixed between the two partition plates 10.

[0034] The upper photovoltaic panel 3 has two connecting plates 11 fixedly connected to its bottom. Vertical support rods 12 and L-shaped support rods 13 are hinged to the sides of both connecting plates 11. The bottoms of the two vertical support rods 12 and the two L-shaped support rods 13 are hinged to the sides of two partition plates 10. Worm gears 503 and medium gears 504 are fixed to the inner and outer sides of the hinge points between the two vertical support rods 12 and the partition plates 10, respectively. The L-shaped L-shaped support rods 13 are located below the partition plates 10, serving to support the upper photovoltaic panel 3 and reducing some of the weight of the rotating support rod 507. The inner and outer sides of the hinge points between the two L-shaped support rods 13 and the partition plates 10 are... The lower photovoltaic panel 2 is fixed with a medium gear 506 and a worm gear 505. Cavities 502 are opened on both sides of the lower photovoltaic panel 2. Teeth 501 are installed in both cavities 502. As the lower photovoltaic panel 2 moves outward, the cavities 502 on both sides move with the lower photovoltaic panel 2. The teeth 501 cause the medium gear 1 504 and the medium gear 2 506 to rotate, thereby driving the vertical support rod 12 and the L-shaped support rod 13 to make circular motion in the opposite direction to the lower photovoltaic panel 2. The medium gear 1 504 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, thereby improving the stability of the upper photovoltaic panel 3.

[0035] Large gear 509 is fixedly connected to the outer side of both connecting plates 11. The two large gears 509 are connected to the rotating support rod 507 through a transmission component. The transmission component includes large gear 509, large gear 511, roller 512, belt 510, and small gear 513. Rollers 512 are fixedly connected to the sides of both large gears 509 and large gear 511. A belt 510 is installed between each pair of rollers 512. Small gears 513 are meshed above both large gears 511. The rotating support rod 507 is fixedly connected to the outer side of both small gears 513. The belt 510 mounted on the roller 512 rotates, driving the roller 512 behind it to rotate, causing the intermediate gear 506 to rotate, which in turn drives the meshing pinion 513 to rotate. The pinion 513 is fixedly connected to the rotating support rod 507. The pinion 513 can drive the rotating support rod 507 to rotate and unfold. The belt 510 has the advantages of high efficiency and quiet operation in transmitting power. Grooves 508 are provided on both the left and right sides of the upper photovoltaic panel 3, and the rotating support rod 507 can be retracted into the grooves 508, ensuring the portability of the housing 1 and preventing damage to the rotating support rod 507.

[0036] In use, this foldable solar photovoltaic power generation device with ventilation and heat dissipation function is in a folded state. It requires manual pulling of the lower photovoltaic panel 2 from the side using handle 4, causing the lower photovoltaic panel 2 to move laterally. During this outward movement, 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 this outward movement, the intermediate gears 504 and 506, located at the hinge point of the vertical support rod 12 and the L-shaped support rod 13 at the partition plate 10, are located within the cavities 502 and are tightly engaged with the teeth 501 when not pulled. When the lower photovoltaic panel 2 moves outward, the teeth 501 cause the intermediate gears 504 and 506 to rotate, thereby driving the vertical support rod 12 and the L-shaped support rod 13 to perform a circular motion in the opposite direction to the lower photovoltaic panel 2. During the outward circular motion of the upper photovoltaic panel 3, the large gear 509 at the hinged top of the L-shaped support rod 13, located on the outer side of the connecting plate 11, rotates synchronously. The large gear 509 drives the roller 512 on its outer side to rotate synchronously. The belt 510 mounted on the roller 512 rotates, driving the roller 512 behind it to rotate, causing the large gear 511 to rotate. The large gear 511 meshes with the small gear 513, causing the large gear 511 to drive the meshing small gear 513 to rotate. The small gear 513 is fixedly connected to the rotating support rod 507. The small gear 513 can drive the rotating support rod 507 to rotate and unfold, allowing the rotating support rod 507 to contact the ground, share the weight of the upper photovoltaic panel 3, and provide support, thus improving the stability of the upper photovoltaic panel 3. At the same time, by simply pulling open the lower photovoltaic panel 2, the upper photovoltaic panel 3 and the rotating support rod 507 can be unfolded synchronously, improving the convenience of folding.

[0037] Example 2, please refer to Figure 1 - Figure 6Both worm gears 503 and 505 have worms 606 meshing below them. These worm gears generate greater force, allowing the pin 601 to penetrate deeper into the soil, making the housing 1 more stable and preventing accidental tipping. Supports 604 are fixedly connected to the outer sides of both partition plates 10. There are two supports 604 on each worm 606, of equal size and identical shape, for a total of four. Horizontal plates 607 are fixedly connected to both ends of the two worms 606. Openings are provided on the front and rear outer sides of both partition plates 10. There are four slide grooves 609, and each of the four slide grooves 609 is fixedly connected to a top plate 605. Each of the four top plates 605 is fixedly connected to a spring 603. When the horizontal plate 607 rotates in the opposite direction, the spring 603, through its elastic force, moves the two T-shaped vertical slide plates 602 and the two T-shaped rack slide plates 608 upwards to their initial positions. The two front slide grooves 609 are slidably connected to the T-shaped vertical slide plates 602, and the two rear slide grooves 609 are slidably connected to the T-shaped rack slide plates 608. Pins 601 are fixedly connected to the bottom of 02 and the two T-shaped rack and pinion slides 608. The rotation of worm gear one 503 and worm gear two 505 causes the meshing worm 606 to rotate. Horizontal plates 607 are located at both ends of the worm 606. The rotation of the worm 606 causes the horizontal plates 607 to rotate as well. The rotating horizontal plates 607 abut against the protruding parts of the T-shaped vertical slide 602 and the T-shaped rack and pinion slide 608, causing the entire T-shaped vertical slide 602 and T-shaped rack and pinion slide 608 to descend, thereby lowering the T-shaped vertical slide 602 and T-shaped rack and pinion slide 608. The pins 601 fixed below the slide plate 608 extend out of the box body 1 and are firmly inserted into the soil below the box body 1. There are three pins 601 below each of the two T-shaped vertical slide plates 602 and the two T-shaped toothed slide plates 608, for a total of twelve pins, which are arranged vertically. The multiple pins 601 can make the box body 1 more tightly inserted, improving the stability of the box body 1. At the same time, the pins 601 can be retracted into the box body 1 at any time, improving the portability of the box body 1 and preventing sharp spikes from injuring people and causing unnecessary casualties.

[0038] In use, based on Embodiment 1, while pulling the lower photovoltaic panel 2, the applied force causes the intermediate gear 1 504 and intermediate gear 2 506 to rotate, and the worm gear 1 503 and worm gear 2 505 rotate accordingly, causing the meshing worm 606 to rotate. The worm 606 has horizontal plates 607 at both ends; as it rotates, the horizontal plates 607 also rotate. Previously, the rotating horizontal plates 607 were parallel to the protruding parts of the T-shaped vertical slide plate 602 and the T-shaped rack slide plate 608. However, when the horizontal plates 607 rotate, they abut against 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 T-shaped rack slide plate 608 to rotate. The box 1 descends, causing the pins 601 fixed below the T-shaped vertical slide plate 602 and the T-shaped rack and pinion slide plate 608 to extend out of the box 1 and firmly insert into the soil below the box 1, making the entire box 1 more stable. When retracting, the worm gear 1 503 and the worm gear 2 505 rotate in opposite directions, causing the worm 606 to rotate in the opposite direction. The horizontal plate 607 at the end of the worm 606 returns to its initial state, and the entire T-shaped vertical slide plate 602 and the T-shaped rack and pinion slide plate 608 are pulled back to their initial state by the action of the spring 603 above. In this way, the entire box 1 is fixed stably, and the box 1 is a cube when retracted, which can be transported and moved more conveniently.

[0039] Example 3, please refer to Figure 1 - Figure 8Based on Embodiments 1 and 2, external heat dissipation holes 701 are provided on both sides of the housing 1. Large airflow guide holes 705 are provided opposite the handle 4. Air enters through the external heat dissipation holes 701 and blows inward. Since the front is closed, the air passes through the upper part of the lower photovoltaic panel 2 or blows into the inner heat dissipation hole 707, through the partition plate 10 and the gap inside the housing 1, and finally blows out through the external heat dissipation holes 701, forming an air duct to fully dissipate heat from the entire housing 1. Two airflow guide holes 704 are fixedly connected to the outer periphery of the large airflow guide hole 705, arranged symmetrically on the left and right sides, to collect air into the large airflow guide hole 705. A baffle plate 703 is installed on the lower inner side of the large airflow guide hole 705. Medium gears 702 are fixedly connected to the left and right sides of the baffle plate 703. The intermediate gear 702 meshes with the T-shaped rack and pinion slide plate 608 on the right side. The upper photovoltaic panel 3 has shading plates 706 fixedly connected to both sides. The lower photovoltaic panel 2 has a shading groove 708 at the end furthest from the handle 4. When the upper photovoltaic panel 3 moves upward, the shading plates 706 fixedly connected to both sides below it rise, allowing airflow through the external heat dissipation holes 701 on the housing 1. The T-shaped rack and pinion slide plate 608 moves downward, causing the intermediate gear 702 meshing with it to rotate. The rotation of the intermediate gear 702 drives the shading plate 703 downward, opening the large airflow guide hole 705, creating an air duct and improving heat dissipation efficiency. The housing 1 has a total of thirty-six external heat dissipation holes 701, and the two partition plates 10 have a total of eleven internal heat dissipation holes 707. This prevents dust from entering the heat dissipation holes when the device is not in use, thus improving heat dissipation efficiency.

[0040] In use, based on Embodiments 1 and 2, first, lower the housing 1 with the large airflow hole 705 facing the direction from which the wind blows. This creates an airflow channel inside the housing 1. The lower photovoltaic panel 2 moves outward, causing the vertical support rod 12 and L-shaped support rod 13 to rotate, which in turn moves the upper photovoltaic panel 3 upward. This raises the shading plates 706 fixedly connected to both sides below the upper photovoltaic panel 3, allowing airflow through the external heat dissipation holes 701 on the housing 1. Simultaneously, as the worm gear 606 rotates, the T-shaped rack and pinion slide 608 moves downward, causing the intermediate gear 702 meshing with the T-shaped rack and pinion slide 608 to rotate. The rotation of the intermediate gear 702 drives the shading plate 703 to move downward, opening the large airflow hole 705. The wind collector shroud 704 outside the large air guide hole 705 can also collect more air to form an air duct. The air enters from the large air guide hole 705 and exits from the inner heat dissipation hole 707 and the outer heat dissipation hole 701, which can better alleviate the heat generated by the photovoltaic panel when it is working. When it is retracted, the cover plate 703 moves down and the upper photovoltaic panel 3 retracts into the housing 1, blocking the outer heat dissipation hole 701. Meanwhile, the intermediate gear 3 702 rotates, causing the cover plate 703 to move upward and block the large air guide hole 705. The lower part of the cover plate 703 will also be stuck into the cover plate groove 708, so that when the device is idle, dust will not enter due to the open state of the outer heat dissipation hole 701 and the large air guide hole 705, which would damage the internal components. At the same time, it can also improve the heat dissipation efficiency.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
