[0051] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0052] Please see Figures 1 to 5 This invention provides a containerized photovoltaic power generation system, including a container 1 and at least one photovoltaic module 2. The container 1 is hollow inside and has an opening at the top. The photovoltaic module 2 includes a photovoltaic element 21, a lifting element 22, and a rotating element 23. The photovoltaic element 21 is slidably disposed on the container 1 through the opening. The lifting element 22 includes a lifting part 221, which has a fixed end and a telescopic end. The fixed end of the lifting part 221 is connected to the container 1, and the telescopic end can move up and down relative to the container 1 along the opening direction. The rotating element 23 has a fixed end and a movable end. The fixed end of the rotating element 23 is connected to the telescopic end of the lifting part 221, and the movable end is connected to the photovoltaic element 21, for driving the photovoltaic element 21 to rotate relative to the container 1.

[0053] In this device, the interior of the cabin 1 is hollow and the top is open. At least one photovoltaic module 2 and the opening are slidably built into the cabin 1. The photovoltaic module 21 is connected to the lifting component 22. The lifting component 22 can drive the photovoltaic module 21 to move up and down relative to the cabin 1 along the direction of the opening at the top of the cabin 1, so as to place the photovoltaic module 21 outside the cabin 1. The fixed end of the rotating component 23 is connected to the lifting component 22, and the movable end of the rotating component 23 is connected to the photovoltaic module 21, so that the photovoltaic module 21 rotates relative to the cabin and is positioned relative to the solar light source.

[0054] Compared to existing technologies, by using the lifting component 22 to lift the photovoltaic component 21, the photovoltaic component 21 can be stored inside or placed outside the cabin 1 to generate electricity. At the same time, the rotating component 23 connects the photovoltaic component 21 to the lifting component 22, allowing the photovoltaic component 21 to rotate relative to the lifting component 22 and always be positioned relative to the solar source, thereby extending the peak power generation time. This solves the technical problem in existing technologies where the solar module needs to be fixed for use and cannot be adjusted for applicability as the sun moves, resulting in a short peak power generation time.

[0055] Furthermore, the cabin 1 in this device is a common and readily available container structure on the market, which is convenient for outdoor use in the field or remote areas. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0056] like Figures 3 to 6As shown, the photovoltaic component 21 includes at least two photovoltaic panels 211 and at least one hinge 212. The two photovoltaic panels 211 are hinged together by at least one hinge 212 and are foldable. One photovoltaic panel 211 is connected to the rotating end of the first drive unit 222.

[0057] The photovoltaic component 21 consists of multiple photovoltaic panels 211 and multiple hinges 212. Two adjacent photovoltaic panels 211 are connected by hinges 212 to form a hinged folding structure, which is used to improve the power generation of the photovoltaic power generation system.

[0058] Furthermore, the photovoltaic panel 211 here consists of a frame, photovoltaic modules, and electrical connection wires, etc. The photovoltaic panel 211 here is a common and readily available device on the market. This is a conventional setup known to those skilled in the art, and will not be described in detail here.

[0059] like Figure 6 , Figure 7 As shown, the lifting component 22 also includes a first driving part 222, which has a fixed end and an extended end. The fixed end of the first driving part 222 is connected to the cabin 1, and the extended end is connected to the lifting part 221, for driving the telescopic end of the lifting part 221 to extend or shorten relative to the cabin 1.

[0060] The movement of the elongated end of the first drive unit 222 relative to the fixed end drives the lifting unit 221 to move, ultimately enabling the photovoltaic component 21 to be placed outside the cabin 1 or stored inside the cabin 1.

[0061] One implementation method is, for example Figure 6 , Figure 7 As shown, the lifting unit 221 includes a first section rod 2211, a second section rod 2212, and at least one third section rod 2213. The first section rod 2211 is arranged along the direction of the opening, and one end of the first section rod 2211 is connected to the inner wall of the cabin 1, and the other end is provided with a first slot along its length. One end of the second section rod 2212 is slidably inserted into the first slot, and the other end is provided with a second slot along its length. One end of the third section rod 2213 is slidably inserted into the second slot, and the other end is provided with a third slot along its length. At least one third section rod 2213 is slidably fitted along the guide cross-sectional area of ​​the first section rod 2211, decreasing sequentially and slidingly according to diameter. The photovoltaic element 21 is connected to the third section rod 2213.

[0062] The first section rod 2211, the second section rod 2212, and at least one third section rod 2213 are sequentially slidably assembled to form a lifting part 221 with telescopic function, which is not only simple in structure but also highly stable.

[0063] As another implementation, the cross-sections of the first rod 2211, the second rod 2212, and the third rod 2213 are all in a "C" shape. The first driving part 222 includes a first pulley 2221, an electric handwheel 2222, and a connecting rope 2223. The first pulley 2221 is arranged on one side of the first rod 2211 and is connected to the inner wall of the cabin 1. The electric handwheel 2222 is rotatably connected to the cabin 1. One end of the connecting rope 2223 is connected to the third rod 2213, the other end is wound around the first pulley 2221, and is connected to the electric handwheel 2222. The connecting rope 2223 can be wound around the electric handwheel 2222 to drive the first rod 2211, the second rod 2212, and the third rod 2213 to slide relative to each other.

[0064] Utilize the fixed pulley group composed of the connecting rope 2223 and the first pulley. By rotating the electric handwheel 2222, the length of the connecting rope 2223 is changed to achieve the elongation or shortening of the lifting part 221.

[0065] Specifically, a groove is formed on one side wall of the cabin 1 in this device. At least one communication hole connected to its interior is formed on the groove. The electric handwheel 2222 is rotatably arranged in the groove. The other end of the connecting rope 2223 passes through the communication hole and is connected to the electric handwheel 2222 on the outer wall of the cabin 1.

[0066] Furthermore, the connecting rope 2223 here is a steel wire rope commonly found in the market and easy to purchase. The electric handwheel 2222 is a device commonly found in the market and easy to purchase, which can achieve two driving modes: electric drive or manual drive. The first pulley 2221, the electric handwheel 2222, and the connecting rope 2223 are all conventional settings well-known to those skilled in the art, and will not be described in detail here.

[0067] Specifically, the first driving part 222 in this device further includes a second pulley. The second pulley is fixedly connected to the third rod 2213. One end of the connecting rope 2223 is wound around the second pulley to reduce the friction and resistance of the relative movement of the first rod 2211, the second rod 2212, and the third rod 2213, and improve the stability of the device operation. Details will not be elaborated here.

[0068] As Figure 8 shown, the rotating part 23 includes a second driving part 231 and a third driving part 232. The second driving part 231 has a fixed end and a rotating end. The rotating end of the second driving part 231 is connected to the photovoltaic element 21 to drive the photovoltaic element 21 to rotate around an axis perpendicular to the opening. The third driving part 232 has a fixed end and a rotating end. The fixed end of the third driving part 232 is connected to the third rod 2213, and the rotating end is connected to the fixed end of the second driving part 231 to drive the photovoltaic element 21 to rotate around an axis in the direction of the opening.

[0069] The second drive unit 231 drives the plane containing the photovoltaic panel 211 to rotate about an axis perpendicular to the opening, and the third drive unit 232 drives the plane containing the photovoltaic panel 211 to rotate about an axis perpendicular to the opening. The cooperation of the second drive unit 231 and the third drive unit 232 ensures that the plane containing the photovoltaic panel 211 is always positioned relative to the solar light source, thus extending the peak power generation time.

[0070] Specifically, the second drive unit 231 in this device includes a rotating shaft and a second drive motor. The rotating shaft is fixedly connected to the photovoltaic panel 211. The fixed end of the second drive motor is connected to the third rod 2213, and the output shaft is connected to the rotating shaft. It can drive the photovoltaic panel 211 to rotate relative to the third rod 2213 around its rotation axis. Further details will not be elaborated here.

[0071] Furthermore, the third drive unit 232 includes a left fan blade, a right fan blade, and a first drive motor. The left fan blade is fixedly connected to the third section rod 2213, and the right fan blade is fixedly connected to the fixed end of the second drive motor and can rotate relative to the left fan blade. The fixed end of the first drive motor is connected to the left fan blade, and the output shaft is connected to the right fan blade, which can drive the right fan blade, the fixed end of the third drive unit 232 to rotate relative to the left fan blade and the third section rod 2213 around their rotation axis.

[0072] Specifically, in this device, the photovoltaic module 2 also includes a light sensor. The light sensor can help determine the position of the solar source relative to the photovoltaic panel 211 and convert the position information into control signals for the first drive motor and the second drive motor to achieve the following of the photovoltaic panel 211 relative to the solar source. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0073] like Figures 1 to 5 As shown, the device also includes a telescopic partition 3, at least one cooling fan 4, an integrated unit 5, a control panel 6 and a battery 7, and a load connector 8.

[0074] The telescopic partition 3 is positioned opposite the opening and can be extended or retracted to open or block the opening.

[0075] The telescopic partition 3 is a foldable telescopic structure that can open and close the top opening of the cabin 1, facilitating the folding and unfolding of the photovoltaic panel 211.

[0076] Furthermore, the telescopic partition 3 here is a common and readily available setup on the market, and is a conventional setup known to those skilled in the art, so it will not be described in detail here.

[0077] One implementation method is, for example Figure 3 , Figure 4 As shown, at least one heat dissipation hole is provided on one side wall of the cabin 1, which is connected to the interior of the cabin. The cooling fan 4 is embedded in the heat dissipation hole and connected to the cabin 1.

[0078] Cooling fan 4 is used to dissipate the heat generated inside the cabin 1 in a timely manner, thereby improving the stability of the device operation.

[0079] As another implementation method, such as Figure 2 As shown, the integrated unit 5 is built into the cabin 1 and is electrically connected to the electric handwheel 2222, the second drive unit 231, the third drive unit 232, the telescopic partition 3 and the cooling fan 4. The control panel 6 is embedded in the side wall of the cabin 1 and is electrically connected to the integrated unit 5. The battery 7 is connected to the inner wall of the cabin 1 and is electrically connected to the photovoltaic panel 211, the control panel 6 and the integrated unit 5.

[0080] The all-in-one unit 5 is connected to the control panel 6, and is also electrically connected to the electric handwheel 2222, the second drive unit 231, the third drive unit 232, the telescopic partition 3, and the cooling fan 4 to achieve automated control and facilitate use. The battery 7 is used to store electrical energy for convenient use.

[0081] Furthermore, the all-in-one machine 5, control panel 6, and battery 7 are all common and readily available components on the market. These are conventional components known to those skilled in the art and will not be described in detail here.

[0082] As another implementation method, such as Figures 1 to 3 As shown, the load plug-in terminal 8 is located on the side wall of the compartment 1 and is electrically connected to the battery 7.

[0083] The load plug 8 is designed to meet temporary charging needs outdoors and is convenient to use.

[0084] The specific workflow of this invention is as follows: the interior of the cabin 1 is hollow and the top is open. At least one photovoltaic module 2 and the opening are slidably built into the cabin 1. The photovoltaic module 21 is connected to the lifting component 22. The lifting component 22 can drive the photovoltaic module 21 to move up and down relative to the cabin 1 along the direction of the opening at the top of the cabin 1, so as to place the photovoltaic module 21 outside the cabin 1. The fixed end of the rotating component 23 is connected to the lifting component 22, and the movable end of the rotating component 23 is connected to the photovoltaic module 21, so that the photovoltaic module 21 rotates relative to the cabin and is positioned relative to the solar light source. Compared with the prior art, by using the lifting component 22 to drive the photovoltaic module 21 to move up and down, the photovoltaic module 21 can be stored inside the cabin 1 or placed outside the cabin 1 to generate electricity. At the same time, the rotating component 23 connects the photovoltaic module 21 and the lifting component 22, so that the photovoltaic module 21 can rotate relative to the lifting component 22 and is always positioned relative to the solar light source, thereby extending the peak power generation time.

[0085] In use, the user first uses the control panel 6 and the all-in-one machine 5 to control the operation of the telescopic partition 3 to open the opening at the top of the cabin 1. Then, the all-in-one machine 5 controls the electric handwheel 2222 to rotate, and the length of the connecting rope 2223 is shortened after rotation, so that the third section rod 2213, the second section rod 2212 and the first section rod 2211 are relatively extended, driving the photovoltaic panel 211 to rise outside the cabin 1. Then, the user manually unfolds the multiple photovoltaic panels 211, so that the multiple photovoltaic panels 211 extend along the plane and are fully opened. Finally, the first drive motor and the second drive motor are controlled to work based on the position information of the solar source collected by the sensor, so that the photovoltaic panel 211 is always positioned relative to the solar source.

[0086] Furthermore, when it is necessary to store the photovoltaic panel 211 inside the cabin 1, the user first controls the first drive motor and the second drive motor to adjust the plane on which the photovoltaic panel 211 is located so that it is parallel to the plane on which the third section rod 2213 is located. Then, the user manually folds the multiple photovoltaic panels 211. Finally, the user manually or electrically controls the electric handwheel 2222 to rotate, thereby retracting the third section rod 2213 relative to the cabin 1 and driving the photovoltaic panel 211 to be stored inside the cabin 1.

[0087] Furthermore, the device contains multiple photovoltaic modules 2, which are arranged sequentially at intervals. The spacing between two adjacent photovoltaic modules 2 can be set according to actual power generation needs to avoid mutual interference.

[0088] This device, through the aforementioned structure, can solve the technical problem in the prior art where the solar module needs to be used in a fixed position and cannot be adjusted for applicability as the sun moves, resulting in a short peak power generation time.

[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
