Description

Technical Field

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Photovoltaic brackets are structural systems used to support and fix photovoltaic modules, ensuring stable operation of photovoltaic modules in outdoor environments. According to the application scenarios, they can be divided into photovoltaic brackets for ground power stations, rooftop power stations and distributed power generation; according to whether the photovoltaic modules are rotatable, they can be divided into fixed brackets, single-axis tracking brackets and dual-axis tracking brackets. However, it is inconvenient to use electricity outdoors, and many of them use solar panels to generate electricity. At this time, the installation bracket of the solar panel is required to be simple and easy to fold and store. After storage, it can also be convenient to transport and will not take up too much space.

[0004] There are public solar power stations in the prior art, and the solar brackets can be raised and lowered to adjust the installation angle, but most of them are raised and lowered by oil cylinders or electric cylinders, which require a power source. If electricity is used, it is necessary to connect to the power supply. If oil cylinders are used, the oil cylinders need to be maintained, which makes the entire device difficult to maintain. Moreover, the oil cylinders or electric cylinders also occupy a certain volume. Even after the brackets are stored, they cannot be completely stored, which is inconvenient to transport.

[0005] The prior art also has a foldable mounting bracket, which is specifically folded by flipping. The flipping method also cannot return to the side of the support column, and the overall space occupied still has a large problem. Summary of the Invention

[0041] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0042] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0043] As introduced in the background technology, the photovoltaic support device in the prior art requires a power source and has a large overall footprint. In order to solve the above technical problems, the present invention proposes a foldable and retractable integrated photovoltaic support device.

[0044] Example 1

[0045] In a typical embodiment of the present invention, referring to Figure 1 and Figure 2As shown, a foldable and retractable integrated photovoltaic support device includes a column 1, a support assembly 3 and a connector 8 are provided on at least one side of the column 1, one end of the support assembly 3 is rotatably connected to the column 1, the support assembly 3 includes at least two telescopic arms, the latter telescopic arm can be extended or retracted relative to the former telescopic arm, each telescopic arm is installed with a photovoltaic bracket 7, the photovoltaic brackets 7 at the two adjacent telescopic arms are overlapped and connected and can slide relative to each other, one end of the connector 8 is movably connected to the column 1, and the other end of the connector 8 can support the support assembly 3. When the telescopic arm of the support assembly 3 is retracted, the connector 8 is detached from the support assembly 3, and the support assembly 3 can return to the side of the column 1.

[0046] It should be noted that one, two or more support assemblies 3 are provided on the side of the column 1. After the support assembly 3 is opened, the support assembly 3 is stably supported by the connector 8. After the telescopic arm of the support assembly 3 is unfolded, one or more solar panels can be supported. The specific size is determined by the size of the solar panel. If the size of the solar panel is large, a group of multiple photovoltaic brackets in a group of support assemblies can support the solar panel. If the photovoltaic size is adapted to the size of the photovoltaic bracket 7, the support of multiple solar panels can be achieved through a group of support assemblies.

[0047] Of course, in some examples, one or more solar panels may be supported by two adjacent support assemblies 3;

[0048] The length of the telescopic arm is determined according to actual needs. The telescopic arm may include two or three arms, or other numbers. In this embodiment, the telescopic arm includes three sections, the first two sections of which are hollow structures, and the third section 3-3 may be a solid rod or a hollow rod. From the first section of the telescopic arm connected to the column to the last section of the telescopic arm, the outer diameter of each section of the telescopic arm gradually decreases.

[0049] In some examples, if the number of telescopic arms is greater than 3, there is a problem of structural stability. The support assembly can be supported by two connectors, one of which is inside and the other is outside. Alternatively, the two connectors support the support assembly in a herringbone structure to ensure stable support of the support assembly. It is easy to understand that the connector 8 can be a connecting rod or a connecting plate, and the connecting plate has a set thickness to ensure support strength.

[0050] Because the photovoltaic brackets need to slide relative to each other, when the number of telescopic arms is 3, 3 photovoltaic brackets are also set at the support assembly 3. The first photovoltaic bracket 7-1 is fixed at the first section of the telescopic arm, the second photovoltaic bracket is fixed at the second section of the telescopic arm, one end of the second photovoltaic bracket 7-2 is fixed to the end of the second section of the telescopic arm through the L-shaped frame 6, and the other end is connected to the first photovoltaic bracket 7-1 through a roller structure or a guide structure, and the third photovoltaic bracket 7-3 is fixed at the third section of the telescopic arm 3-3. One end of the third photovoltaic bracket 7-3 is fixed to the end of the third section of the telescopic arm 3-3 through the L-shaped frame 6, and the other end is connected to the second photovoltaic bracket 7-2 through a roller structure or a guide structure. In this way, the first photovoltaic bracket 7-1, the second photovoltaic bracket 7-2 and the third photovoltaic bracket 7-3 are not arranged in the same plane, and each photovoltaic bracket 7 is respectively provided with a threaded hole. When the solar panel is supported by multiple photovoltaic brackets, the distance between the third photovoltaic bracket and the solar panel is the shortest, but the connection between the solar panel and the first photovoltaic bracket 7-1 and the second photovoltaic bracket 7-2 can still be achieved by using longer bolts.

[0051] It should be noted that the photovoltaic bracket 7 has a set width, the telescopic arm can be a rectangular tube (composed of cold-finished thin-walled components), and the width of the photovoltaic bracket 7 is greater than the width or diameter of the telescopic arm. Of course, the width of the photovoltaic bracket can also be equal to the width of the telescopic arm.

[0052] In addition, it is easy to understand that when the support assembly 3 is retracted, the length of the support assembly 3 is less than the height of the column 1, and further less than the distance between the connection between the support assembly 3 and the column 1 and the bottom of the column, so that the support assembly 3 can be retracted to the side of the column. After the support assembly 3 is retracted, in order to avoid the support assembly from extending outward during transportation, the entire device also includes an elastic ring. The elastic ring can be supported by rubber material, and the elastic ring is put on the circumferential direction of the entire device to avoid the problem of the support assembly extending outward relative to the column.

[0053] In this embodiment, the column 1 has a set height, and a mounting plate is fixed to the bottom end of the column 1, and the mounting plate is fixed to the ground by multiple column foot bolts 2. The first section of the telescopic arm 3-1 is hingedly connected to the top of the column 1 by a pin 4, so that the support assembly 3 can rotate around the column. The size of the connection between the top of the column 1 and the support assembly 3 is increased to strengthen the connection with the support assembly 3. A support column 10 is set at the top of the column, and an arc plate 9 is set at the top of the support column. The arc plate 9 is used to limit the rotation angle of the support assembly 3 relative to the column, and plays a positioning role. After the support assembly 3 is unfolded to a set angle relative to the column, it is preliminarily positioned by the arc plate.

[0054] It is easy to understand that a first recess is provided on the side of the column 1 , into which the connecting member can be placed when retracted, and the retraction of the connecting member into the first recess will not interfere with the return of the support assembly;

[0055] In addition, it is easy to understand that a transition plate is provided at the first section of the telescopic arm 3-1 connected to the column 1, and the transition plate is tilted relative to the first section of the telescopic arm 3-1. The transition plate is provided with a third opening, and the connecting member is connected to the third opening of the transition plate. A fastener such as a bolt passes through the connecting member 8 and is provided with the third opening, so that a stable connection of the support assembly 3 is achieved through the connecting member. There are multiple transition plates along the first section of the telescopic arm, and the connection between the connecting member 8 and different transition plates can realize the adjustment of the angle of the support assembly; the connection position of the connecting member and the column is lower than the connection position of the support assembly with the column.

[0056] Of course, in other examples, a transition plate may be provided, and there are multiple options for connectors with different lengths. A connector of appropriate length may be selected based on the angle of the solar panel relative to the central axis of the column.

[0057] It should be noted that the connection between two adjacent sections of photovoltaic brackets 7 is achieved through a roller structure or a guide structure, which not only ensures the connection between the two adjacent photovoltaic brackets 7, but also enables the photovoltaic bracket 7 to move along with the movement of the telescopic arm.

[0058] Specifically, when the telescopic arm is provided with three sections, the first photovoltaic bracket 7-1 and the second photovoltaic bracket 7-2 supported by the first two sections of the telescopic arm, namely the first section of the telescopic arm 3-1 and the second section of the telescopic arm 3-2, are respectively provided with a slide groove 12, and the slide groove 12 is arranged along the length direction of the telescopic arm on which it is located. The second photovoltaic bracket 7-2 and the third photovoltaic bracket 7-3 are installed with a roller 11 or a guide part 14 on the side facing the telescopic arm. The roller 11 or the guide part 14 is arranged in the middle or side of the photovoltaic bracket, and the roller 11 or the guide part 14 is located in the slide groove 12 of the previous section of the photovoltaic bracket. The arrangement of the roller or the guide part facilitates the rapid movement of the telescopic arm along the slide groove.

[0059] refer to Figure 3 As shown, when the guide portion 14 is provided in the rear section of the photovoltaic bracket in the two adjacent telescopic arms, the guide portion 14 is an I-shaped structure, one end of the guide portion 14 is connected to the rear section of the photovoltaic bracket, and the slide groove 12 in the front section of the photovoltaic bracket is an inverted T-shape, ensuring a stable connection between the guide portion 14 and the slide groove 12. Specifically, the guide portion 14 includes two sections connected in sequence, the first section is a conical section, and the second section is a rectangular section. The first section is connected to the T-frame, and the T-frame is connected to the photovoltaic bracket 7. The shape of the slide groove 12 in the front section of the photovoltaic bracket is adapted to the shape of the guide portion 14.

[0060] refer to Figure 4As shown, when the roller 11 is set on the rear section of the photovoltaic bracket in the two adjacent telescopic arms, the front section of the photovoltaic bracket is hollow, and one side of the photovoltaic bracket is open. The roller 11 is connected to the rear section of the photovoltaic bracket through a T-frame 13, so that the roller 11 can move smoothly along the slide groove. Rollers are set on both sides of the T-frame, and the roller 11 is rotatable relative to the T-frame. The T-frame passes through the open part of the photovoltaic bracket.

[0061] In addition, it should be noted that a first opening is provided in the front telescopic arm of the two adjacent telescopic arms, and a fastener passes through the first opening to limit the rear telescopic arm. The fastener 5, such as a fastening bolt, passes through the front telescopic arm and is fixed to the rear telescopic arm or limits the end of the rear telescopic arm to limit the rear telescopic arm.

[0062] In order to achieve the connection between the telescopic arm and the photovoltaic bracket 7, the telescopic arm supports one end of the photovoltaic bracket 7 through a support frame. The photovoltaic bracket 7 is provided with a plurality of mounting holes for connection with the solar cell panel.

[0063] The support device provided in this embodiment has a support assembly 3 and a connector 8 provided on a column 1. The connector 8 is used to support the support assembly 3. The support assembly 3 includes multiple telescopic arms, and photovoltaic brackets are installed on the telescopic arms. The photovoltaic brackets of two adjacent telescopic arms are overlapped and can slide relative to each other. In this way, when the support assembly 3 is unfolded relative to the column 1, the photovoltaic bracket is also unfolded. When the connector does not support the support assembly, the support assembly 3 can be retracted and rotated to the side of the column 1. In this way, the overall volume is smaller when stored, which is convenient for transportation. The overall structure does not require a power source or electricity, and is more effectively suitable for outdoor use.

[0064] Example 2

[0065] This embodiment provides a working method of a foldable and retractable integrated photovoltaic support device, including the following contents:

[0066] Fix the column 1 to the ground with the column foot bolts 2;

[0067] After the support assembly 3 is flipped relative to the column 1 at a set angle, the support assembly 3 is supported by the connecting member 8;

[0068] The telescopic arm in the support assembly 3 is extended. During the extension process, the photovoltaic bracket at the rear telescopic arm slides relative to the front photovoltaic bracket. After the telescopic arm is in place, the fastener 5 passes through the corresponding telescopic arm to limit the position of the next photovoltaic bracket;

[0069] The solar panels are supported by photovoltaic brackets at the support components.

[0070] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
