The bottom surface of the fixed plate is fixedly connected with a first support frame. The outer side of the bottom of the first support frame is fixedly sleeved with a first fixing sleeve.

The height of the photovoltaic panel cannot be reduced to clean the surface of the photovoltaic panel. 3. It is not convenient for installation. Each part needs to be installed one by one, and the installation efficiency is low. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to disclose a deployable photovoltaic module, which is realized by the following technical solutions.

[0006] A deployable photovoltaic module includes a photovoltaic panel assembly, two first support rods, two second support rods, and a bottom plate. It is characterized in that the photovoltaic panel assembly is composed of at least two first photovoltaic panels;

[0007] The first photovoltaic panel is composed of a photovoltaic panel main body. Two limit plates are respectively arranged on both sides below the photovoltaic panel main body. A limit rack is arranged below the limit plate. A through sliding groove is formed in the middle of the limit plate. A sliding pin is also arranged at the left end of the outer surface of the limit plate. The width of the latter first photovoltaic panel is smaller than the inner distance between the two limit plates of the previous first photovoltaic panel. The sliding pin of the latter first photovoltaic panel is inserted into the sliding groove of the previous first photovoltaic panel and can slide along the sliding groove of the previous first photovoltaic panel;

[0008] The bottom plate is composed of a bottom plate main body and four first support seats located above the bottom plate main body. The distance between the two first support seats on the left side of the bottom plate main body is the same as the distance between the two limit plates on the first photovoltaic panel. The distance between the two first support seats on the right side of the bottom plate main body is the same as the distance between the two limit plates on the third photovoltaic panel. The first support seat is composed of two first bushings. The bottoms of the two first bushings are connected by a first connecting component. A first shaft hole is formed in the middle of the first bushing, and a plurality of first limit holes are formed around the first shaft hole.

[0009] The two first support rods are located below the first first photovoltaic panel. The first support rod is composed of a first support rod main body, a fastening component, a clamping seat, and a rotating component. The clamping seat is located at the upper end of the first support rod main body, and the rotating component is located at the lower end of the first support rod main body.

The rotating component is located below the first support rod main body. A plurality of teeth are provided on the surface of the rotating component. Two rotating shafts are formed on both sides of the rotating component and are located in the first shaft holes of the corresponding first support seats. The rotating component can rotate around the first shaft hole. A limit pin is inserted between one of the first limit holes of the corresponding first support seat and the corresponding two teeth to fix the angle of the first support rod.

[0010] The two second support rods are located below the last first photovoltaic panel. The second support rod is composed of a first support rod main body, a fastening component, a clamping seat, and a rotating component.

[0011] For the above-mentioned extendable photovoltaic module, the next photovoltaic panel can be drawn out from below the previous photovoltaic panel, which can save space when not in use. At the same time, the light-facing angle of the photovoltaic panel can be adjusted by the angles of the first support rod and the second support rod and the length of the photovoltaic panel drawn out in the photovoltaic panel combination, which is simple and convenient.

[0012] For the above-mentioned extendable photovoltaic module, the first support rod main body is characterized by being composed of an upper rod and a lower rod. The upper rod can be retracted into the lower rod. A third limit hole is formed in the upper part of the lower rod. A plurality of third limit holes are arranged at intervals on the upper rod. The length of the first support rod is fixed by inserting a limit pin through the third limit hole on the lower rod and one of the third limit holes on the upper rod.

[0013] For a stretchable photovoltaic module described above, the first support rod and the second support rod can be telescopically adjusted in length, which makes it more convenient to adjust the angle of the photovoltaic panel assembly with respect to light. At the same time, the height of the photovoltaic panel assembly can also be adjusted, facilitating the cleaning of the surface of the photovoltaic panel assembly.

[0014] For a stretchable photovoltaic module described above, it is characterized in that a T-shaped slider is provided at the bottom of the first connecting member of the two first support seats located on the upper left side of the bottom plate main body.

[0016] For a stretchable photovoltaic module described above, it is characterized in that the width of the limit teeth of the limit rack is greater than the width of the clamping seat.

[0017] For a stretchable photovoltaic module described above, it is characterized in that the material of the first support rod is steel.

[0018] For a stretchable photovoltaic module described above, it is characterized in that the material of the second support rod is steel.

[0019] For a stretchable photovoltaic module described above, it is characterized in that the angle between the connecting lines of the centers of two adjacent first limit holes and the center of the first shaft hole is the same as the angle between the connecting lines of two adjacent teeth on the rotating member and the center of the rotating member.

[0020] For a stretchable photovoltaic module described above, it is characterized in that the width of the first connecting member is greater than the width of the bottom of the T-shaped groove, preventing the upper part of the T-shaped groove from being bent.

[0021] For a stretchable photovoltaic module described above, it is characterized in that the distance between the two sliding pins on the last first photovoltaic panel is greater than the distance between the two sliding grooves on the previous first photovoltaic panel.

[0022] For a stretchable photovoltaic module described above, by sliding the T-shaped slider 435, the photovoltaic panel assembly 1 can be compressed to the lowest position, and then the photovoltaic panel assembly 1 can be retracted, reducing the height and width of the entire photovoltaic panel. There is no need to disassemble the entire photovoltaic panel during installation and transportation, which is convenient and practical.

[0023] Therefore, the present invention has beneficial effects such as simple structure, small volume, convenient installation, convenient transportation, and convenient cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
