Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a photovoltaic power generation device with an easy-to-store structure. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, has been widely used. However, existing photovoltaic power generation equipment has many limitations in practical use. Traditional photovoltaic power generation equipment typically uses fixed photovoltaic panel arrays, which have a large and fixed overall structure, making them difficult to store and move. When the equipment needs to be transported, moved to a different location, or stored for a long time, its large size not only occupies a lot of space but also increases transportation costs and difficulties. In some space-limited application scenarios, such as small courtyards or temporary facilities, the excessively large size of the equipment also restricts its installation and use. During transportation or storage, traditional photovoltaic (PV) power generation equipment is prone to surface scratches and damage from shaking and collisions, affecting power generation efficiency and even causing equipment malfunctions. Furthermore, traditional PV power generation equipment lacks convenient mobility mechanisms; moving the equipment to different locations with varying sunlight often requires additional handling tools or multiple people, significantly reducing the flexibility and convenience of equipment use. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic power generation device with a convenient storage structure, comprising: The base plate has a retractable mechanism installed on its top. The retractable mechanism can reduce the height of the equipment and reduce the vertical space occupied. A fixed frame is fixedly installed on the top of the retractable mechanism. Universal wheels are fixedly installed at the four corners of the bottom of the base plate. The universal wheels allow the equipment to move flexibly and make it easy to adjust its position in different places and adapt to different lighting environments. A storage mechanism is installed on top of a fixed frame. The storage mechanism horizontally stores the photovoltaic panels, reducing the floor space occupied. The storage mechanism includes a fixed frame plate, which is fixedly installed on the top of a fixed frame. A main photovoltaic panel is fixedly installed on the upper surface of the fixed frame plate. A storage component is installed on the side of the fixed frame plate, and a secondary photovoltaic panel 1 and a secondary photovoltaic panel 2 are installed on the storage component. The secondary photovoltaic panel 1 and the secondary photovoltaic panel 2 are symmetrically arranged on both sides of the main photovoltaic panel. The secondary photovoltaic panel 2 is located above the secondary photovoltaic panel 1. The length of the secondary photovoltaic panel 2 and the secondary photovoltaic panel 1 is half that of the main photovoltaic panel. A connecting component 1 and a connecting component 2 are respectively installed on the side of the two secondary photovoltaic panels 2. The connecting component 1 and the connecting component 2 are interlocked and adapted. The photovoltaic panel is used to receive solar energy and convert it into electrical energy.

[0004] Preferably, protective pads are fixedly installed on the lower surfaces of both the first and second auxiliary photovoltaic panels. During storage, when the first and second auxiliary photovoltaic panels overlap, the protective pads can effectively prevent direct contact and friction between the photovoltaic panels, avoid damage to the photovoltaic panel surface, and protect the power generation performance of the photovoltaic panels. A cover plate is rotatably installed on the side of the second auxiliary photovoltaic panel via a pivot. After the storage mechanism has finished storing the photovoltaic panel, it rotates to cover the photovoltaic panel, protecting it from pollution and erosion by external dust, rainwater, debris, etc., and extending the service life of the photovoltaic panel.

[0005] Preferably, the storage component includes a first rotating shaft, a first connecting rod, and a second connecting rod. The first rotating shaft is rotatably mounted on the side of the fixed frame plate. A transmission gear and an L-shaped rod are fixedly mounted on the outer surface of the first rotating shaft. The first rotating shaft is located at the bend of the L-shaped rod. The second rotating shaft is rotatably mounted on one end of the L-shaped rod. The second rotating shaft is fixedly mounted on the side of the first auxiliary photovoltaic panel.

[0006] Preferably, a rotating shaft four and a rotating shaft five are rotatably installed at both ends of the connecting rod one, the rotating shaft four is fixedly installed on the side of the fixed frame plate, the rotating shaft five is fixedly installed on the side of the secondary photovoltaic panel two, and a rotating shaft three is rotatably installed in the middle of the connecting rod one, the rotating shaft three is fixedly installed on the side of the secondary photovoltaic panel one.

[0007] Preferably, a rotating shaft six and a rotating shaft seven are rotatably installed at both ends of the connecting rod two, with the rotating shaft six fixedly installed on the side of the sub-photovoltaic panel one and the rotating shaft seven fixedly installed on the side of the sub-photovoltaic panel two.

[0008] Preferably, there are two rotating shafts, and the two rotating shafts are symmetrically arranged on both sides of the fixed frame plate. The two transmission gears mesh with each other. The end of the L-shaped rod away from the rotating shaft is rotatably connected to a push-pull rod through a rotating shaft. The other end of the push-pull rod is rotatably mounted with a rotating shaft eight. There are two push-pull rods, and the ends of the two push-pull rods away from the L-shaped rod are rotatably connected through a rotating shaft eight. A handle is fixedly installed at the end of the rotating shaft eight. The meshing of the transmission gears ensures that the rotating shafts on both sides rotate synchronously, so that the secondary photovoltaic panel one and the secondary photovoltaic panel two can be symmetrically and smoothly unfolded or retracted.

[0009] Preferably, the L-shaped rod, connecting rod one, and connecting rod two are arranged in parallel, and are symmetrically arranged on both sides of the fixed frame plate. When the handle is pulled, the push-pull rod drives the L-shaped rod to rotate around the rotating axis one, and the L-shaped rod pulls the sub-photovoltaic panel one to move. At this time, connecting rod one and connecting rod two rotate, and sub-photovoltaic panel two moves. When the docking part one and docking part two are engaged, sub-photovoltaic panel two and sub-photovoltaic panel one overlap with the main photovoltaic panel, which greatly reduces the horizontal footprint.

[0010] Preferably, the first docking component includes a first docking block, the outer surface of the first docking block is provided with a trapezoidal groove, the two sides of the first docking block are provided with sliding grooves, a sliding rod is slidably installed inside the sliding groove, a fixing plate is fixedly installed at the end of the sliding rod, a return spring is fixedly connected between the fixing plate and the side of the first docking block, and the return spring is sleeved on the outer surface of the sliding rod.

[0011] Preferably, the second docking component includes a second docking block. A trapezoidal block is fixedly installed on the outer surface of the second docking block. The trapezoidal block is engaged with a trapezoidal groove, and the trapezoidal groove is pressed against a sliding rod. Slots are provided on both sides of the trapezoidal block, and the slots are engaged with the sliding rod. When the two secondary photovoltaic panels approach each other, the trapezoidal block of the second docking block is inserted into the trapezoidal groove of the first docking block. At the same time, the trapezoidal block presses against the sliding rod, causing it to slide in the groove and stretch the return spring. When the trapezoidal block is fully inserted into the trapezoidal groove, the sliding rod is reset and ejected under the action of the return spring, and is engaged in the slots on both sides of the trapezoidal block, thus achieving a stable connection between the two secondary photovoltaic panels and ensuring the structural stability of the photovoltaic panel assembly after storage.

[0012] Preferably, the retraction mechanism includes a cylinder, a first fixed plate, and a second fixed plate. The first fixed plate and the second fixed plate are respectively fixedly installed on both sides of the base plate. The top of the first fixed plate and the second fixed plate are respectively fitted with a first sleeve plate and a second sleeve plate. A connecting rod is fixedly connected between the opposite surfaces of the first sleeve plate and the second sleeve plate. The cylinder is fixedly installed on the top of the base plate. A telescopic rod is fixedly connected to the telescopic end of the cylinder. The top of the telescopic rod is fixedly connected to the lower surface of the connecting rod. Driven by the cylinder, the first sleeve plate and the second sleeve plate slide up and down along the first fixed plate and the second fixed plate, driving the fixed frame to rise and fall synchronously. The first sleeve plate and the second sleeve plate are respectively installed inside the first sleeve plate and the second sleeve plate. The first cushioning spring and the second cushioning spring are respectively fixedly connected to the top of the first fixed plate and the second fixed plate. The cushioning springs can absorb the impact force during the movement, reduce equipment vibration, and protect the internal structure and photovoltaic panel from damage.

[0013] This invention provides a photovoltaic power generation device with an easy-to-store structure. It has the following beneficial effects: I. This photovoltaic power generation equipment, featuring an easy-to-store structure, utilizes a retraction mechanism. The cylinder's telescopic end drives a telescopic rod up and down, which pulls or pushes a connecting rod, thereby causing sleeve plates one and two to slide on fixed plates one and two, achieving the lifting and lowering of the fixed frame and upper structure. During this lifting and lowering process, buffer springs one and two compress or extend. The retraction mechanism allows for flexible adjustment of the equipment height. When the equipment is stored and needs to be placed, its height can be lowered, reducing the vertical footprint and facilitating storage and transportation. Buffer springs one and two provide cushioning and shock absorption during lifting and lowering, protecting the internal structure and photovoltaic panels, extending the equipment's lifespan, and improving its stability and reliability.

[0014] II. This photovoltaic power generation equipment features a convenient storage structure. Through its storage mechanism, pulling the handle causes an L-shaped rod to rotate around a pivot axis via a push-pull rod. The L-shaped rod pulls the secondary photovoltaic panel, while connecting rods one and two rotate, causing the secondary photovoltaic panel two to move as well. This causes the secondary photovoltaic panel one and two to overlap with the main photovoltaic panel. At this point, the connecting piece one and connecting piece two engage. After storage, the cover plate rotates to close the photovoltaic panel. This storage mechanism allows the secondary photovoltaic panel one and two to be stored when the equipment is not in use or needs to be transported, significantly reducing the horizontal footprint of the equipment and facilitating its handling, storage, and management.

[0015] Third, this photovoltaic power generation equipment with an easy-to-store structure, through the setting of docking parts one and two, allows for a secure connection of the two secondary photovoltaic panels during storage. When the two secondary photovoltaic panels approach and overlap each other, the trapezoidal block on docking part two inserts into the trapezoidal groove of docking part one. The trapezoidal groove compresses the sliding rod, causing it to slide within the groove and stretching the return spring. When the trapezoidal block is fully inserted, the sliding rod, under the action of the return spring, is engaged in the slots on both sides of the trapezoidal block. Docking parts one and two achieve a stable connection of the secondary photovoltaic panels in the stored state, ensuring the structural stability of the photovoltaic panel assembly after storage, preventing damage caused by photovoltaic panel shaking or collisions, and ensuring the safety of the equipment.

[0016] Fourth, this photovoltaic power generation equipment with an easy-to-store structure, through the setting of protective pads, ensures that when the auxiliary photovoltaic panels one and two overlap with the main photovoltaic panel during the storage process, the protective pads on the lower surfaces of the auxiliary photovoltaic panels one and two contact the surface of the main photovoltaic panel, preventing direct friction and collision between the auxiliary photovoltaic panels and the main photovoltaic panel during the storage and overlapping process, avoiding damage to the photovoltaic materials on the surface of the photovoltaic panel, protecting the power generation performance of the photovoltaic panel, and extending the service life of the photovoltaic panel.

[0017] Fifth, this photovoltaic power generation equipment, with its easy-to-store structure, features casters that allow for easy movement in all directions when needed. Once the target location is reached, the casters can be locked to secure the equipment. The casters provide excellent mobility, facilitating flexible movement in different locations and under varying lighting conditions to obtain optimal sunlight and improve power generation efficiency.

A secondary photovoltaic panel 43 and a secondary photovoltaic panel 44 are installed on the storage component 49. The secondary photovoltaic panel 43 and the secondary photovoltaic panel 44 are symmetrically arranged on both sides of the main photovoltaic panel 42. The secondary photovoltaic panel 44 is located above the secondary photovoltaic panel 43. The length of the secondary photovoltaic panel 44 and the secondary photovoltaic panel 43 is half that of the main photovoltaic panel 42. A first docking component 46 and a second docking component 47 are respectively installed on the side of the two secondary photovoltaic panels 44. The first docking component 46 and the second docking component 47 are interlocked and adapted. The photovoltaic panel is used to receive solar energy and convert it into electrical energy. Protective pads 48 are fixedly installed on the lower surfaces of both auxiliary photovoltaic panels 43 and 44. During storage, when auxiliary photovoltaic panels 43 and 44 overlap, the protective pads 48 can effectively prevent direct contact and friction between the photovoltaic panels, avoid damage to the photovoltaic panel surface, and protect the power generation performance of the photovoltaic panels. A cover plate 45 is rotatably installed on the side of auxiliary photovoltaic panel 44 via a pivot. After storage is completed, the cover plate 45 is rotated to cover the photovoltaic panel, protecting it from external dust, rainwater, debris, and other contaminants, thus extending the service life of the photovoltaic panel. The storage component 49 includes a first rotating shaft 4901, a first connecting rod 4908, and a second connecting rod 4911. The first rotating shaft 4901 is rotatably mounted on the side of the fixed frame plate 41. A transmission gear plate 4902 and an L-shaped rod 4903 are fixedly mounted on the outer surface of the first rotating shaft 4901. The first rotating shaft 4901 is located at the bend of the L-shaped rod 4903. A second rotating shaft 4904 is rotatably mounted on one end of the L-shaped rod 4903. The second rotating shaft 4904 is fixedly mounted on the side of the first auxiliary photovoltaic panel 43. Rotating shaft 4906 and rotating shaft 4907 are rotatably installed at both ends of connecting rod 4908. Rotating shaft 4906 is fixedly installed on the side of fixed frame plate 41, and rotating shaft 4907 is fixedly installed on the side of secondary photovoltaic panel 44. Rotating shaft 4905 is rotatably installed in the middle of connecting rod 4908. Rotating shaft 4905 is fixedly installed on the side of secondary photovoltaic panel 43. The two ends of the connecting rod 2 4911 are respectively rotatably mounted with rotating shaft 6 4909 and rotating shaft 7 4910. Rotating shaft 6 4909 is fixedly installed on the side of the auxiliary photovoltaic panel 1 43, and rotating shaft 7 4910 is fixedly installed on the side of the auxiliary photovoltaic panel 2 44. There are two rotating shafts 4901, and the two rotating shafts 4901 are symmetrically arranged on both sides of the fixed frame plate 41. The two transmission gears 4902 mesh with each other. The end of the L-shaped rod 4903 away from the rotating shaft 4904 is rotatably connected to the push-pull rod 4912 through the rotating shaft. The other end of the push-pull rod 4912 is rotatably mounted with the rotating shaft 4914. There are two push-pull rods 4912, and the ends of the two push-pull rods 4912 away from the L-shaped rod 4903 are rotatably connected through the rotating shaft 4914. The end of the rotating shaft 4914 is fixedly mounted with a handle 4913. The meshing of the transmission gears 4902 ensures that the rotating shafts 4901 on both sides rotate synchronously, so that the auxiliary photovoltaic panel 43 and the auxiliary photovoltaic panel 44 can be symmetrically and smoothly unfolded or retracted. L-shaped rod 4903, connecting rod one 4908, and connecting rod two 4911 are arranged in parallel, and are symmetrically arranged on both sides of the fixed frame plate 41. When the handle 4913 is pulled, the push-pull rod 4912 drives the L-shaped rod 4903 to rotate around the rotating shaft one 4901. The L-shaped rod 4903 pulls the secondary photovoltaic panel one 43 to move. At this time, connecting rod one 4908 and connecting rod two 4911 rotate, and the secondary photovoltaic panel two 44 moves. When the first docking part 46 and the second docking part 47 are engaged, the secondary photovoltaic panel two 44 and the secondary photovoltaic panel one 43 overlap with the main photovoltaic panel 42, which greatly reduces the horizontal footprint.

[0023] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 5 and Figure 6As shown, the docking component 46 includes a docking block 461. A trapezoidal groove 462 is formed on the outer surface of the docking block 461. Sliding grooves 463 are formed on both sides of the docking block 461. A sliding rod 464 is slidably installed inside the sliding groove 463. A fixing plate 465 is fixedly installed at the end of the sliding rod 464. A return spring 466 is fixedly connected between the fixing plate 465 and the side of the docking block 461. The return spring 466 is sleeved on the outer surface of the sliding rod 464. The second docking component 47 includes a second docking block 471. A trapezoidal block 472 is fixedly installed on the outer surface of the second docking block 471. The trapezoidal block 472 is engaged with the trapezoidal groove 462 and is pressed against the slide rod 464. The trapezoidal block 472 has slots 473 on both sides, which are engaged with the slide rod 464. When the two secondary photovoltaic panels 44 approach each other, the trapezoidal block 472 of the second docking block 471 is inserted into the trapezoidal groove 462 of the first docking block 461. At the same time, the trapezoidal block 472 presses the slide rod 464, causing it to slide in the groove 463 and stretch the return spring 466. When the trapezoidal block 472 is fully inserted into the trapezoidal groove 462, the slide rod 464 is reset and popped out under the action of the return spring 466, and is engaged in the slots 473 on both sides of the trapezoidal block 472, thus realizing a stable connection between the two secondary photovoltaic panels 44 and ensuring the stability of the photovoltaic panel assembly structure after storage. The retraction mechanism 2 includes a cylinder 21, a first fixing plate 23, and a second fixing plate 24. The first fixing plate 23 and the second fixing plate 24 are respectively fixedly installed on both sides of the base plate 1. A first sleeve plate 25 and a second sleeve plate 26 are respectively fitted onto the top of the first fixing plate 23 and the second fixing plate 24. A connecting rod 27 is fixedly connected between the opposing surfaces of the first sleeve plate 25 and the second sleeve plate 26. The cylinder 21 is fixedly installed on the top of the base plate 1. A telescopic rod 22 is fixedly connected to the telescopic end of the cylinder 21. The top of the telescopic rod 22 is fixedly connected to the connecting rod 27. On the lower surface, driven by cylinder 21, sleeve plate 1 25 and sleeve plate 26 slide up and down along fixed plate 1 23 and fixed plate 24, driving fixed frame 3 to rise and fall synchronously. Buffer spring 1 28 and buffer spring 29 are respectively installed inside sleeve plate 1 25 and sleeve plate 26. Buffer spring 1 28 and buffer spring 29 are respectively fixedly connected to the top of fixed plate 1 23 and fixed plate 24. The buffer springs can absorb the impact force during the movement, reduce equipment vibration, and protect the internal structure and photovoltaic panel from damage.

[0024] When the equipment is stored, the operator pulls the handle 4913. The handle 4913 drives the push-pull rod 4912 through the rotating shaft 4914. The push-pull rod 4912 drives the L-shaped rod 4903 to rotate around the rotating shaft 4901. Since the transmission gears 4902 on the two rotating shafts 4901 are meshed, the two L-shaped rods 4903 will rotate synchronously. The L-shaped rod 4903 pulls the auxiliary photovoltaic panel 43 to rotate, moving it closer to the main photovoltaic panel 42. At the same time as the auxiliary photovoltaic panel 43 moves, the connecting rod 4908 and the connecting rod 4911 rotate, driving the auxiliary photovoltaic panel 44 to rotate, also moving it closer to the main photovoltaic panel 42. When the second auxiliary photovoltaic panel 44 and the first auxiliary photovoltaic panel 43 move to overlap with the main photovoltaic panel 42, the first docking piece 46 and the second docking piece 47 engage. During docking, the trapezoidal block 472 on the second docking block 471 inserts into the trapezoidal groove 462 of the first docking block 461. At the same time, the trapezoidal groove 462 presses against the sliding rod 464, causing it to slide within the sliding groove 463 and stretching the return spring 466. When the trapezoidal block 472 is fully inserted into the trapezoidal groove 462, the sliding rod 464, under the action of the return spring 466, engages into the slots 473 on both sides of the trapezoidal block 472, completing the engagement and fixation. After storage, rotate the cover plate 45 on the side of the secondary photovoltaic panel 44 to cover the photovoltaic panel and provide protection. When cylinder 21 is activated, the telescopic end of cylinder 21 drives telescopic rod 22 to move downward. Telescopic rod 22 pulls connecting rod 27, which in turn causes sleeve 1 25 and sleeve 26 to slide downward on fixed plate 1 23 and fixed plate 24. Buffer spring 1 28 and buffer spring 29 are compressed, and the fixed frame 3, the storage mechanism 4 above, and the photovoltaic panel as a whole are lowered, reducing the height of the equipment and the vertical footprint. The equipment can be easily moved by casters 5 and placed in a suitable position.
