Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a photovoltaic power generation device that is easy to store. Background Technology

[0002] With the increasing global demand for renewable energy, solar photovoltaic power generation technology has been widely used. In addition to large-scale fixed photovoltaic power plants, portable and mobile photovoltaic power generation devices are playing an increasingly important role in outdoor activities, emergency disaster relief, military operations, and temporary power supply scenarios.

[0003] Most portable devices use traditional rigid solar panel designs. Due to the lack of a targeted storage mechanism, existing devices are often loose after storage, lacking a unified fixing and protection structure. On the one hand, during transportation, the photovoltaic panels may shake or collide, causing edge damage or loosening of internal circuit connections, affecting the device's lifespan. On the other hand, the loose panel structure makes it difficult for a single person to carry conveniently, especially in scenarios requiring rapid relocation such as emergency rescue and field operations, increasing manpower burden and deployment time. Therefore, we propose a method for easily storing photovoltaic power generation devices to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for easily storing photovoltaic power generation devices. This solves the problem that traditional photovoltaic devices lack an effective storage and fixing structure, resulting in the folded panels being in a loose state. This not only makes the components prone to damage during handling due to shaking and collisions, but also exposes defects such as inconvenience in carrying and low deployment efficiency in emergency scenarios, seriously restricting the practicality and reliability of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic power generation device that is easy to store, including a photovoltaic module;

[0006] The photovoltaic module consists of multiple sets of photovoltaic panels, and a connector is provided between two adjacent sets of photovoltaic panels, allowing the two sets of photovoltaic panels to rotate relative to each other around a first axis.

[0007] A storage mechanism is located on one side of the photovoltaic module and is used to store the photovoltaic module.

[0008] Preferably, the connecting component is a hinge, a bushing hinge, or a snap-fit ​​shaft.

[0009] Preferably, the storage mechanism is a foldable storage design, and the storage mechanism includes a storage box disposed on one side of the photovoltaic module. One side of the photovoltaic module is connected to the storage box via a hinge. Multiple photovoltaic panels of the photovoltaic module can be folded into the cavity of the storage box via connectors. A limiting cover is provided at the opening of the storage box, and locking members arranged symmetrically are installed between the limiting cover and the storage box.

[0010] Preferably, the locking component includes pin seats fixed on both sides of the limiting cover plate. The pin seats have circular holes with bolt rods inside. The storage box has a threaded hole on one side that matches the bolt rod. One end of the bolt rod passes through the circular hole and is screwed into the threaded hole for connecting and locking the limiting cover plate and the storage box.

[0011] Preferably, a handle is fixedly installed on the upper surface of the storage box.

[0012] Preferably, the storage mechanism is a roller-type storage design. The storage mechanism includes symmetrically arranged limiting plates on one side of the photovoltaic module. A roller shaft is rotatably installed between the two sets of limiting plates via bearings. One side of the photovoltaic module is connected to the roller shaft via a hinge. A symmetrically arranged binding strap is fixedly installed at the other end of the photovoltaic module.

[0013] Preferably, the tightening strap adopts a belt-type design, including a belt body, a buckle disposed at one end of the belt body, and a plurality of meshing teeth or a series of through holes disposed in the other direction of the belt body.

[0014] Beneficial effects

[0015] This invention provides a method for easily storing photovoltaic power generation devices. Compared with existing technologies, it has the following advantages:

[0016] This easily stored photovoltaic power generation device utilizes two innovative storage methods: multi-panel folding and stacking, and roller winding, to significantly reduce the volume of the photovoltaic modules. The folding and stacking scheme allows multiple photovoltaic panels to form a "panel-like stack" with a thickness only a few times that of a single panel. The roller winding scheme tightly winds flexible or segmented photovoltaic modules around a roller shaft. Both methods greatly reduce the space occupied by the device when not in use, allowing it to be flexibly stored in various narrow areas. While significantly improving space utilization and portability, it effectively avoids component damage during transportation and storage, perfectly solving the pain points of traditional photovoltaic equipment being inconvenient to carry and occupying too much space in mobile scenarios such as outdoor travel and emergency power supply. This improves the effectiveness of this structure and meets practical usage needs. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figures 1-5 As shown:

[0028] A photovoltaic power generation device that is easy to store includes a photovoltaic module 1;

[0029] Photovoltaic module 1 consists of multiple sets of photovoltaic panels, and there is a connector between two adjacent sets of photovoltaic panels, which enables the two sets of photovoltaic panels to rotate relative to each other around a first axis. The connector is a hinge, a bushing hinge, or a snap-on rotating shaft.

[0030] Storage mechanism 2 is located on one side of photovoltaic module 1 and is used to store photovoltaic module 1. Storage mechanism 2 is a foldable storage design and includes a storage box 201 located on one side of photovoltaic module 1. One side of photovoltaic module 1 is connected to storage box 201 by a hinge. Multiple photovoltaic panels of photovoltaic module 1 can be folded into the cavity of storage box 201 through connectors. A limiting cover 202 is provided at the opening of storage box 201. A locking device is installed between the limiting cover 202 and storage box 201 in a symmetrical arrangement.

[0031] The locking component includes pin seats 203 fixed on both sides of the limiting cover plate 202. The pin seats 203 have circular holes and bolt rods 204 are provided in the circular holes. The storage box 201 has a threaded hole 205 on one side that matches the bolt rod 204. One end of the bolt rod 204 passes through the circular hole and is screwed into the threaded hole 205 for connecting and locking the limiting cover plate 202 and the storage box 201. A handle 206 is fixedly installed on the upper surface of the storage box 201.

[0032] In this implementation plan: When the photovoltaic power generation device is in use, it is confirmed that the device is in a non-working state and the connection between the photovoltaic module 1 and the external electrical equipment is disconnected. At this time, the multiple photovoltaic panels of the photovoltaic module 1 are connected by connectors, which can be hinges, bushings, or snap-on shafts. Hinges are preferred to improve the smoothness of rotation and keep the device in the unfolded state. The limiting cover 202 is locked to the storage box 201 by locking components. The handle 206 on the storage box 201 is designed to facilitate subsequent handling.

[0033] Hold the end of the bolt rod 204 and rotate it counterclockwise to gradually unscrew the bolt rod 204 from the threaded hole 205 on the side wall of the storage box 201 until the bolt rod 204 is completely disengaged from the threaded hole 205. Then temporarily remove the bolt rod 204 from the pin seats 203 on both sides. At this time, the locking state between the limiting cover plate 202 and the storage box 201 is released. The limiting cover plate 201 can be flipped open around its connecting shaft or hinge with the storage box 201 to expose the internal cavity of the storage box 201.

[0034] Starting with the photovoltaic panel furthest from the storage box 201, adjacent photovoltaic panels are sequentially rotated relative to each other around the first axis of the connector. For example, if photovoltaic module 1 consists of 3 sets of photovoltaic panels, the outermost 3rd set of photovoltaic panels is first folded towards the middle 2nd set of photovoltaic panels, so that the backs of the two sets of photovoltaic panels are in contact. Then, the folded "2nd and 3rd sets of photovoltaic panels" are folded towards the 1st set of photovoltaic panels closer to the storage box 201, so that the 3 sets of photovoltaic panels completely overlap, forming a "plate-like stack" with a thickness only a few times that of a single photovoltaic panel. During this process, the connector must ensure smooth rotation while limiting the rotation angle of the photovoltaic panels to avoid excessive rotation that could damage the edges of the photovoltaic panels or the connecting wires.

[0035] Push the folded "plate-like stack" into the internal cavity of the storage box 201, ensuring that the photovoltaic module 1 is completely inside the cavity and that the hinge connecting it to the storage box 201 is in its natural state without excessive pulling. Then, replace the limiting cover 202 on the opening of the storage box 201, aligning the pin seats 203 on both sides with the threaded holes 205 on the storage box 201; pass the bolt shank 204 through the circular hole of the pin seat 203 and screw it clockwise into the threaded hole 205 until the head of the bolt shank 204 is tightly fitted with the pin seat 203, thus locking the limiting cover 202 and the storage box 201. At this point, the photovoltaic module 1 is stably confined inside the storage box 201 and can be easily moved using the handle 206.

[0036] If you need to use the device, simply reverse the steps above. First, unlock and open the limiting cover 202, then take out the photovoltaic module 1 from the storage box 201 and unfold it one by one. Finally, connect it to the external power equipment to generate photovoltaic power.

[0037] Example 2:

[0038] like Figure 6 As shown:

[0039] A photovoltaic power generation device that is easy to store includes a photovoltaic module 1;

[0040] Photovoltaic module 1 consists of multiple sets of photovoltaic panels, and a connector is provided between two adjacent sets of photovoltaic panels, allowing the two sets of photovoltaic panels to rotate relative to each other around a first axis. The connector is a hinge, a bushing hinge, or a snap-fit ​​shaft. Storage mechanism 2 is located on one side of photovoltaic module 1 and is used to store photovoltaic module 1. Storage mechanism 2 is a roller-type storage design. Storage mechanism 2 includes symmetrically arranged limiting plates 207 on one side of photovoltaic module 1. A roller shaft 208 is rotatably installed between two sets of limiting plates 207 via bearings. One side of photovoltaic module 1 is connected to roller shaft 208 via a hinge. The other end of photovoltaic module 1 is fixedly installed with symmetrically arranged tightening straps 209. The tightening straps 209 adopt a belt-type design, including a belt body, a buckle at one end of the belt body, and multiple meshing teeth or a series of through holes in the other direction of the belt body.

[0041] In this implementation plan: it is confirmed that the photovoltaic module 1 has been disconnected from the external connection and is in a non-working state. At this time, the photovoltaic module 1 is in an unfolded state, with one side of it fixedly connected to the roller shaft 208 by a hinge. The roller shaft 208 is mounted between two sets of symmetrically arranged limit plates 207 through bearings and can rotate freely; the two sets of binding straps 209 at the other end of the photovoltaic module 1 are in a loose state and are not bound.

[0042] The operator holds both ends of the roller shaft 208 with both hands and rotates the roller shaft 208 in the preset winding direction. Since the photovoltaic module 1 is connected to the roller shaft 208 by a hinge, the rotation of the roller shaft 208 will drive the connecting end of the photovoltaic module 1 to rotate synchronously, so that the photovoltaic module 1 gradually winds around the outer circumference of the roller shaft 208. During the winding process, it is necessary to keep the winding direction of the photovoltaic module 1 flat to avoid wrinkles or deviation. The two sets of limit baffles 207 can prevent the photovoltaic module 1 from sliding to both sides of the roller shaft 208, ensuring that the wound photovoltaic module 1 is concentrated on the roller shaft 208 between the two sets of limit baffles 207.

[0043] When the photovoltaic module 1 is completely wrapped around the roller shaft 208, that is, when the free end of the photovoltaic module 1 is close to the outer circumference of the roller shaft 208, stop rotating the roller shaft 208. Then take out the two sets of binding straps 209 at the free end of the photovoltaic module 1. Wrap one set of straps around the assembled photovoltaic module 1 and roller shaft 208 after winding, so that the meshing teeth or through holes on the strap are aligned with the buckles of the other set of straps. Lock the straps by fastening them with buckles, such as press-type buckles or pin-type buckles, to ensure that the straps fit tightly against the assembled body and prevent the photovoltaic module 1 from loosening and unfolding during transportation.

[0044] Unlock the fasteners of the binding strap 209 and remove the strap from the assembly; then rotate the roller shaft 208 counterclockwise to gradually unfold the photovoltaic module 1 from the roller shaft 208 until all the photovoltaic panels of the photovoltaic module 1 are on the same plane. Finally, connect the external power equipment and it can be put into use.

[0045] This invention significantly reduces the volume of photovoltaic modules through two innovative storage methods: multi-panel folding and stacking, and roller winding. The folding and stacking scheme allows multiple photovoltaic panels to form a "panel-like stack" with a thickness only a few times that of a single panel. The roller winding scheme tightly winds flexible or segmented photovoltaic modules around a roller shaft. Both methods greatly reduce the space occupied by the device when not in use, allowing it to be flexibly stored in various narrow areas. While significantly improving space utilization and portability, it effectively avoids component damage during transportation and storage. This perfectly solves the pain points of traditional photovoltaic equipment being inconvenient to carry and taking up too much space in mobile scenarios such as outdoor travel and emergency power supply, improving the effectiveness of this structure and meeting practical usage needs.

[0046] like Figure 7 As shown:

[0047] Example 3:

[0048] In an optional embodiment, the photovoltaic module 1 consists of three rows of several groups of photovoltaic panels, and the photovoltaic panels in the middle row are connected to each other by a fabric hinge. The other two groups of photovoltaic panels are connected to the corresponding photovoltaic panels in the middle row by a fabric hinge on one side, and the photovoltaic panel at the head of the middle row is connected to the storage box 201 in the storage mechanism 2.

[0049] In this implementation plan: the photovoltaic panels located on both sides are folded onto the corresponding photovoltaic panel located in the middle through the fabric hinge, and then the photovoltaic panels arranged in a row after being folded are folded together and folded into the storage box 201, and stored by the storage mechanism 2.

[0050] It should be noted that each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is a mature existing technology and is well known to those in the field, so it will not be elaborated further here.

[0051] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0052] It is important to understand that solar panels are connected using male and female connectors for positive and negative connections.

[0053] The MPPT module has its input terminal connected to the output terminal of photovoltaic module 1. The input voltage is matched with the output voltage of photovoltaic module 1 after series and parallel connection, and is used to track the maximum power output point of photovoltaic module 1.

[0054] The inverter module, whose input is connected to the output of the MPPT module, is used to convert DC power into 220V, 50Hz standard household AC power.

[0055] The external socket module, whose input end is connected to the output end of the inverter module, is used to charge the car and supply power to 220V electrical appliances. The MPPT module, inverter module, and external socket module are all installed on the storage mechanism 2.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
