Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module take-up and take-down device. Background Technology

[0002] Currently, the goal of using photovoltaic (PV) modules with corresponding devices is to achieve optimal module storage and protection, as well as maximize power generation when deployed. However, some PV module support designs, in pursuit of better storage, have adopted complex and cumbersome structures. While this improves the ease of deployment, it neglects the optimal angle of sunlight exposure for the modules. The design of supporting devices increasingly restricts the movement trajectory of the modules, thus limiting their deployed position. However, for the actual effectiveness of PV modules, storage and deployment are not the ultimate design objectives. The ultimate goal of PV module design remains maximizing the surface area exposed to sunlight and maximizing power generation efficiency.

[0003] Therefore, it is necessary to further improve the structure to address this design flaw, so that it can be more convenient to deploy and retract without affecting the light-receiving surface of the photovoltaic module and maintaining power generation efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the existing technology, this utility model provides a photovoltaic module storage and deployment device, which can realize convenient storage and quick deployment of modules. While ensuring the convenience of storage, this device can optimize the deployment angle of the modules to maximize the power generation efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a photovoltaic module deployment and retraction device, including a supporting handle, a planetary gear assembly, and a photovoltaic module body; the planetary gear assembly includes an external gear ring, a sun gear, and several planetary gears, the external gear ring is rotatably mounted on the top of the supporting handle, the sun gear is rotatably mounted at the center of the external gear ring and is driven to rotate by the supporting handle, the several planetary gears mesh with the sun gear and the external gear ring respectively, when the external gear ring rotates clockwise relative to the supporting handle, each planetary gear rotates clockwise synchronously; a module support arm is fixed on each planetary gear, the outer end of the module support arm is hinged to the photovoltaic module body; the outer circumference of the external gear ring is provided with support ramps at intervals equal to the number of planetary gears, the support ramps are provided on both sides of the support ramps, the guide ramps are provided with guide inclined surfaces, the guide inclined surfaces are connected to the support ramps, the guide inclined surfaces guide the photovoltaic module upwards along the planetary gear assembly until it is supported by the upper surface of the support ramps.

[0006] In the above scheme, through the planetary gear assembly, when the outer gear ring rotates clockwise relative to the supporting handle, each planetary gear rotates clockwise synchronously. At this time, the outer edge of the photovoltaic module body contacts the guide ramp of the guide auxiliary block as it moves synchronously with the planetary gears. Since the photovoltaic module is hinged to the module support arm, it is guided upward by the guide ramp and folds up along the hinge axis, realizing the unfolding of the photovoltaic module body. In this way, the photovoltaic module can be quickly unfolded and stored by rotating the outer gear ring clockwise and counterclockwise relative to the supporting handle.

[0007] Furthermore, the cross-section of the supporting inclined platform and the guide auxiliary blocks on both sides along the length of the supporting handle is an isosceles trapezoid, and the two sides of the isosceles trapezoid are the guide inclined surfaces.

[0008] Furthermore, the photovoltaic module has a flat plate structure. When the photovoltaic module body is in free fall, the outermost ends of both sides of the flat plate structure are not lower than the outer edge of the guide slope, and the highest point of the support slope is not lower than the hinge position between the outer end of the module support arm and the photovoltaic module body.

[0009] Preferably, the angle formed between the upper surface of the supporting inclined platform and the planetary gear rotation plane is not less than 20°, so that the photovoltaic module body generates an elevation angle of not less than 20° after unfolding, which facilitates solar exposure and ensures power generation efficiency.

[0010] Preferably, the component support arm is a Z-shaped bent structure, with one end fixed to a planetary gear and the other end having a hinge bearing. A hinge pin is fixed to the photovoltaic module body, and the hinge pin engages with the hinge bearing. Through the engagement of the hinge pin and the hinge bearing, the photovoltaic module body is effectively connected to the component support arm, and the photovoltaic module body also has a certain degree of freedom of movement, allowing for angle changes relative to the hinge axis, facilitating unfolding and folding operations.

[0011] Furthermore, several sets of planetary gears are evenly distributed around the sun gear at equal angles.

[0012] Preferably, the number of planetary gears is three and the number of photovoltaic module bodies is three.

[0013] The beneficial effects of this utility model are that the photovoltaic module storage and unfolding device of this utility model has a reasonable structural design and utilizes the motion principle of planetary gears to realize the convenient storage and quick unfolding of the module. While ensuring the convenience of storage, this device can realize the unfolding and angle optimization of the module, laying a good foundation for maximizing power generation efficiency. Compared with conventional devices, it reduces the restriction on the degree of freedom of the module mechanism, and the unfolded appearance is beautiful and has good practicality.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0021] like Figures 1 to 4 The photovoltaic module take-up and take-down device shown is the preferred embodiment of this utility model.

[0022] The photovoltaic module deployment and retraction device includes a support handle 1, a planetary gear assembly, and a photovoltaic module body 3.

[0023] Specifically, the planetary gear assembly includes an external gear ring 101, a sun gear 104, and three planetary gears 2. The external gear ring 101 is rotatably mounted on top of the supporting shank 1. The sun gear 104 is rotatably mounted at the center of the external gear ring 101, and is connected to and driven by the supporting shank 1. The three planetary gears 2 mesh with the sun gear 104 and the external gear ring 101, respectively.

[0024] Based on the synchronous movement of planetary gears 2 driven by the planetary gears 2, each planetary gear 2 is fixed with a component support arm 201. The component support arm 201 has a Z-shaped bent structure, with one end fixed to the planetary gear and the other end having a hinge bearing 202. A hinge pin 301 is fixed on the photovoltaic module body 3, and the hinge pin 301 is connected to the hinge bearing 202. The bent design of the component support arm 201 can effectively improve the support strength, and through the bent design, it can cover more of the support ramp 102 positions, which is convenient for the photovoltaic module to have a larger area of ​​support ramp 102 under the photovoltaic module when it is unfolded to receive sunlight, and a larger contact support area, thereby improving the stability of the support.

[0025] Three support ramps 102 are evenly spaced on the outer circumference of the external gear ring 101. In the initial position, i.e., when the device is not unfolded, there is a support ramp 102 corresponding to the position between two adjacent planetary gears 2. Guide auxiliary blocks 103 are provided on both sides of the support ramps 102. The guide auxiliary blocks 103 are provided with guide ramps, which are connected to the support ramps 102. When the planetary gear assembly rotates, the guide ramps guide the photovoltaic module upwards until it is supported by the upper surface of the support ramps 102. In this way, an approximately hexagonal design is formed on the outer circumference of the upper end of the support handle 1, where three sides correspond to the support ramps 102 and the guide auxiliary blocks 103 on both sides, which are used to realize the unfolding and sun exposure of the module, and the other three sides are left empty to accommodate the photovoltaic module body 3.

[0026] In the actual selection and design, the angle formed between the upper surface of the support ramp 102 and the rotation plane of the planetary gear 2 is not less than 20°, so that the photovoltaic module body 3 can generate an elevation angle of not less than 20° after unfolding, effectively supporting the laying and slightly tilting, so as to ensure solar exposure and power generation efficiency. The cross-section of the support ramp 102 and the guide auxiliary blocks 103 on both sides along the length of the support handle 1 is an isosceles trapezoid, and the two sides of the isosceles trapezoid are the guide ramps. The guide ramps are used to provide an upward force to guide the photovoltaic module after contacting it, so that the photovoltaic module body 3 rotates and folds upward about the axis of the hinge pin 301 as the rotation center, until the photovoltaic module body 3 moves to the support ramp 102, where the support ramp 102 provides stable support force.

[0027] The photovoltaic module body 3 has a flat plate structure. When the photovoltaic module body 3 hangs freely, the outermost ends of both sides of the flat plate structure are not lower than the outer edge of the guide slope, and the highest point of the support slope 102 is not lower than the hinge position between the outer end of the module support arm 201 and the photovoltaic module body 3. Through the cooperation of the hinge pin 301 and the hinge bearing 202, the photovoltaic module body 3 is effectively connected to the module support arm 201. On the other hand, it also allows the photovoltaic module body 3 to have a certain degree of freedom of movement, that is, to change its angle relative to the hinge axis, which facilitates the unfolding and storage operations.

[0028] In this embodiment, the supporting handle 1 serves as the connection structure between the entire device and the ground, and is the most important supporting structure. The supporting handle 1 cooperates with the planetary gear assembly to achieve circular motion of the component in the horizontal plane, ensuring the component's degree of freedom of movement in the horizontal plane. After the planetary gear assembly and the supporting handle 1 cooperate, the photovoltaic component can be tilted up and down relative to the supporting handle 1 in the height direction. Tilting up is achieved by the relative rotation between the supporting handle 1 and the external gear ring 101. Falling occurs after the relative rotation, when the photovoltaic component body 3 rotates to the space between the two supporting ramps 102 and the guide auxiliary block 103, with no secondary support below, and naturally falls under the action of gravity. After the photovoltaic component body 3 is raised relative to the supporting handle 1, the supporting ramps 102 allow the component to lie at an upward angle above them.

[0029] In use, the outer gear ring 101 rotates clockwise relative to the supporting handle 1, and each planetary gear 2 rotates clockwise synchronously. The photovoltaic module body 3 moves synchronously with each planetary gear 2, and the outer edge of the photovoltaic module body 3 contacts the guide slope of the guide auxiliary block 103 when it moves synchronously with the planetary gear 2. Since the photovoltaic module is hinged to the module support arm, after being guided upward by the guide slope, it folds and lifts upward along the hinge axis, realizing the unfolding of the photovoltaic module body 3. In this way, the photovoltaic module can be quickly unfolded and stored by rotating the outer gear ring 101 clockwise and counterclockwise relative to the supporting handle 1. In the actual operation, when the photovoltaic module body 3 moves with the planetary gear 2, it will not only rotate relative to the outer gear ring 101, but also rotate on its own axis. In the practical design of this application, since the outer gear ring 101 itself needs to rotate a very small angle, and the storage and unfolding operations are reciprocating small-amplitude movements, and a guide slope is also designed for guidance, the small rotation generated by the photovoltaic module body 3 during the opening and closing process will not hinder its upward flipping and opening.

[0030] Thus, utilizing the motion principle of planetary gear 2, a device can be achieved for convenient storage and rapid deployment of components. This device ensures convenient storage while optimizing the deployment angle of the components, laying a solid foundation for maximizing power generation efficiency. Compared to conventional devices, its simple structure and lack of complex mechanisms reduce the restrictions on the component's operational freedom, resulting in greater freedom of movement. Furthermore, its aesthetically pleasing appearance after deployment enhances its practicality. In practical applications, the movement between the support handle 1 and the external gear ring 101 can be controlled by a motor, or it can be manually operated via a simple mechanical installation, demonstrating strong versatility. With its attractive appearance, resembling an umbrella when deployed, and its convenient and quick folding structure, the device significantly reduces storage space, minimizing space requirements. It can also be carried in a vehicle for extended use during travel, tourism, and mountain climbing.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
