Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power stations, and in particular to a portable and movable photovoltaic power station. Background Art

[0002] There are currently two types of photovoltaic power generation systems: grid-connected systems and off-grid systems. Grid-connected systems must rely on the power grid to supply power to loads. If the grid is out of power or unstable, they cannot operate normally. Grid-connected systems require fixed installation and are not mobile. They cannot be used in remote areas (such as remote mountainous areas, grasslands, deserts, islands, etc.) or specific occasions. Off-grid systems, on the other hand, do not rely on the power grid, are mobile, can independently supply power to loads, and rely on a control system, making them highly adjustable and having a high comprehensive utilization rate.

[0003] Currently, the most common off-grid system is a carriage-type mobile photovoltaic power station, which generally includes a carriage and a photovoltaic power generation group loaded in the carriage. When in use, the photovoltaic power generation group in the carriage is taken out of the carriage and assembled. When it needs to be moved, the photovoltaic power generation group is disassembled and stored in the carriage. It can be moved at any time and is not dependent on a fixed environment or geographical location.

[0004] However, the inventors found in the actual operation process that when in use, a large space is required for the unfolded photovoltaic power generation group and the carriage, which has the disadvantage of being large in size. Summary of the Invention

[0005] In order to reduce the space occupied by a photovoltaic power station and improve the overall utilization rate of the photovoltaic power station, the present application provides a portable and movable photovoltaic power station.

The bracket assembly is mounted on the frame and constitutes the side wall of the box.

[0008] By adopting the above technical solution, when it is necessary to store the photovoltaic power generation component, the photovoltaic power generation component and the bracket component are disassembled and separated, and then the photovoltaic power generation component is loaded into the box, and the side wall of the box is formed by the bracket component, so that the photovoltaic power generation component is stored in the box, which is convenient for the storage and transportation of the photovoltaic power generation component; the bracket component plays different roles in different forms of the movable photovoltaic power station, and can serve as the side wall of the box together with the box to form a container for loading the photovoltaic power generation component, and can also play the role of its bracket when the photovoltaic power generation component is in use, and play the role of installing and supporting the photovoltaic power generation component. When storing, the bracket originally used to support the photovoltaic power generation component is used, and there is no extra structural waste. The overall structure of the photovoltaic power station has a high utilization rate, and no extra useless structure will be generated before and after storage.

[0009] In addition, when the photovoltaic power generation component is unfolded for use, the bracket assembly is used to install and support the photovoltaic power generation component. At this time, the frame can be used as a storage rack or a placement board can be installed on the frame to form a table. The inverter and battery are always stored in the frame.

[0013] By adopting the above technical solution, the mounting rail is installed in the first slot of the column by plugging, thereby forming the side wall of the box. The mounting rail is easy to assemble and disassemble, and the mounting rail is stably installed on the box and is not easy to fall off.

[0014] Preferably, each of the mounting rails is provided with a mounting track along its length direction, and both sides of the photovoltaic power generation assembly are respectively clamped on the mounting tracks of two adjacent mounting rails.

[0015] By adopting the above technical solution, the photovoltaic power generation component is installed on the mounting rail by a clamping method. The photovoltaic power generation component is easy to unfold, assemble and disassemble, and the purpose of rapid assembly can be achieved. The position of the photovoltaic power generation component on the mounting rail is stable and not easy to fall off. After unfolding, it can provide continuous and stable power supply.

[0016] Preferably, at least one second slot is provided on the mounting rail along its length direction, the photovoltaic power generation assembly includes a photovoltaic power generation panel and a mounting plate, the mounting plate is fixed to one side of the photovoltaic power generation panel, the two sides of the photovoltaic power generation panel are clamped on two adjacent mounting rails, and the two ends of the mounting plate are respectively clamped in two adjacent second slots.

[0017] Preferably, the second slot is arranged in an "L" shape, and the end portion of the mounting plate is arranged in an "L" shape corresponding to the second slot.

[0018] By adopting the above technical solution, the mounting plate can more stably mount the photovoltaic panel on the mounting rail, and the position of the photovoltaic panel on the mounting rail is fixed and not easy to fall off.

[0019] Preferably, the mounting rail is arranged in a "U" shape, and a first diagonal brace is rotatably connected inside the mounting rail. The first diagonal brace can be completely received in the mounting rail. When the first diagonal brace is rotated to form an angle with the mounting rail, the photovoltaic power generation component is unfolded in an inclined shape.

[0020] By adopting the above technical solution, when the photovoltaic power generation component is unfolded for use, the first diagonal brace plays the role of installing the photovoltaic power generation component and supporting the photovoltaic power generation component, so that the photovoltaic power generation component can maintain an inclined unfolded use state and can effectively provide power for a long time; when the photovoltaic power generation component is stored, the first diagonal brace can be completely stored in the installation guide rail, reducing the space occupied by the first diagonal brace when stored, further reducing the space occupied by the photovoltaic power station, and facilitating transportation. At this time, the first diagonal brace is not exposed to the outside, and the installation guide rail protects the first diagonal brace, thereby extending the service life of the first diagonal brace.

[0021] Preferably, it also includes a support assembly, which includes a first base and a second base. When the photovoltaic power generation assembly is unfolded, one end of the mounting rail is connected to the first base, and the end of the first diagonal brace away from the mounting rail is connected to the second base.

[0022] By adopting the above technical solution, the first base and the second base play a role in installing the entire unfolded photovoltaic power generation component, so that the photovoltaic power generation component can be installed in various usage scenarios, such as deserts, grasslands, remote mountainous areas, islands, etc.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-10 This application is described in further detail.

[0045] The present application discloses a portable mobile photovoltaic power station. Figure 1 , which is the storage state of the portable movable photovoltaic power station, including a box body 1, and the interior of the box body 1 is used to load the photovoltaic power generation components 2 that can perform power supply operations.

[0046] Reference Figure 2The box body 1 includes a frame and a bracket assembly, wherein the frame includes a base 11, columns 12 and a top cover 13. The lower surface of the base 11 is connected to a pulley, which can drive the base 11 to move; there are at least three columns 12, and in this embodiment, there are four columns 12, and each column 12 is vertically arranged on the upper surface of the base 11. The four columns 12 are respectively fixed to the respective end angle positions of the upper surface of the base 11 by welding, screwing or plugging. Then, an installation cavity with a loading function is formed between the columns 12, and the photovoltaic power generation components 2, inverters, batteries, etc. for power supply can be placed in the installation cavity. In order to ensure the stable placement of the photovoltaic power generation components 2, inverters, batteries, etc., partitions can also be installed on the upper surface of the base 11 to separate the photovoltaic power generation components 2, inverters, batteries, etc. to prevent the photovoltaic power generation components 2, inverters, batteries, etc. from colliding with each other during transportation.

[0047] Reference Figure 3 The top cover 13 is located at the top of the box body 1. The lower surface of the top cover 13 is provided with an edge. When the top cover 13 is placed on each column 12, the edge of the top cover 13 is exactly in contact with the side of the column 12 away from the installation cavity, so that the top cover 13 is stably installed on the upper end of the column 12. When the box body 1 is moved, the top cover 13 seals and protects the installation cavity, preventing objects inside the installation cavity from being scattered outside and preventing damage to the photovoltaic power station parts. When the box body 1 is not moved, it can be used as a table, and items can be placed on the top cover 13, thus serving two purposes.

[0048] Combine Figure 3 and Figure 4 The bracket assembly includes several mounting rails 14 and support rails 15. Both the mounting rails 14 and the support rails 15 are hollow structures, light in weight, and easy to carry. The mounting rails 14 are stacked and form one of the side walls of the box 1, and the support rails 15 are stacked and form the other side walls of the box 1 except the mounting rails 14. When the photovoltaic power station needs to be used, the mounting rails 14 are removed from the box 1, and then a bracket for installing the photovoltaic power generation component 2 is formed; combined with Figure 4 At this time, each support rail 15 is still installed between adjacent columns 12, and the box body 1 can be used as a table.

[0049] In other embodiments, the bracket assembly may also be composed of a plurality of mounting rails 14. In this case, the mounting rails 14 are stacked, and all side walls of the box 1 are enclosed by the mounting rails 14. When the photovoltaic power station is to be used, the mounting rails 14 are removed from the box 1. The box 1 is then composed of a frame and can also be used as a table.

[0050] The number and position of the mounting rails 14 and the supporting rails 15 are determined by the size of the photovoltaic power station.

[0051] Reference Figure 5 A first vertical slot 121 is provided on both sides of each column 12 along its length direction. The bracket assembly is connected to the first slot 121 of each column 12, and the side wall of the box body 1 is formed by the bracket assembly and the column 12.

[0052] When the mounting rails 14 are stacked and connected between two adjacent columns 12, one method is to insert the ends of each mounting rail 14 into the first slots 121 opposite the two adjacent columns 12. Another method is to set each mounting rail 14 vertically, and the two adjacent long sides of each mounting rail 14 are connected, and the two sides of the side walls formed by the mounting rails 14 are inserted into the first slots 121 opposite the two adjacent columns 12 to achieve the installation of the mounting rails 14. To facilitate the installation of the mounting rails 14 and make the mounting rails 14 more stable on the frame, this application chooses the first method to install the mounting rails 14.

[0053] The first slot 121 is set in a "T" shape, and at this time, the two end portions of the mounting rail 14 are also provided with a "T"-shaped first plug-in block 141 corresponding to the first slot 121, so that the connection between the mounting rail 14 and the column 12 is more stable, and the mounting rail 14 is not easy to fall off from the column 12.

[0054] Correspondingly, the two end portions of the support rail 15 are also provided with a second "T"-shaped plug-in block 151 corresponding to the first slot 121, so that the connection between the support rail 15 and the column 12 is more stable and the support rail 15 is not easy to fall off from the column 12.

[0055] Reference Figure 6 The two sides of the support rail 15 are respectively provided with a first positioning bar 152 and a second positioning bar 153 along the length direction thereof. There are two first positioning bars 152 and two second positioning bars 153. When adjacent support rails 15 are stacked and arranged in the frame, the two first positioning bars 152 on the lower surface of the upper support rail 15 are inserted between the two second positioning bars 153 on the upper surface of the lower support rail 15, or the two second positioning bars 153 on the upper surface of the lower support rail 15 are inserted between the two first positioning bars 152 on the lower surface of the upper support rail 15, or the two first positioning bars 152 on the upper support rail 15 are respectively located on one side of the two second positioning bars 153 on the lower support rail 15, and the first positioning bars 152 and the second positioning bars 153 are arranged in close contact. The cooperation between the first positioning bars 152 and the second positioning bars 153 makes the connection between the two adjacent support rails 15 tighter and more stable.

[0056] Reference Figure 7 and Figure 8The photovoltaic power generation assembly 2 includes a photovoltaic panel 21 and a mounting plate 22. The photovoltaic panel 21 is a solar battery panel, and the mounting plate 22 is connected to the back of the photovoltaic panel 21 by bonding. In addition, the back of each photovoltaic panel 21 is connected to at least one mounting plate 22 by bonding.

[0057] Mounting rails 142 are provided along the length of each side of the mounting rail 14. Both ends and one side of the mounting rails 142 are open. The two sides of the photovoltaic panels 21 are snapped or inserted into the opposing mounting rails 142 of the two adjacent mounting rails 14. The two side walls of the mounting rails 142 are respectively a first mounting side wall and a second mounting side wall. The first and second mounting side walls of the same mounting rail 142 have different widths, facilitating the installation of the photovoltaic panels 21.

[0058] Reference Figure 8 The mounting rail 14 is provided with at least one second slot 143 along its length for receiving the mounting plate 22. The second slot 143 is arranged in an L-shape. The end of the mounting plate 22 is formed into an L-shape corresponding to the second slot 143. The L-shaped structure at the end of the mounting plate 22 is designated as a second insert 151.

[0059] When installing the photovoltaic panel 21 assembly onto the mounting rail 14, first insert the side wall of the photovoltaic panel 21 into the mounting rail 142, then insert the mounting plate 22 into the second slot 143, and then move the mounting plate 22 according to the path of the second slot 143 so that the second plug-in block 151 at the end of the mounting plate 22 is stuck in the second slot 143 to prevent the second plug-in block 151 from detaching from the second slot 143.

[0060] In order to make the connection between the photovoltaic power generation assembly 2 and the mounting rail 14 more stable, the number of the second slots 143 can be increased according to actual needs.

[0061] Reference Figure 9 To ensure a stable stacking connection between two adjacent mounting rails 14, if the first mounting sidewall of one mounting rail 142 is wider than the second mounting sidewall, the second mounting sidewall of the other mounting rail 142 is also wider than the first mounting sidewall. Furthermore, both the first and second mounting sidewalls, facing away from the mounting rails 14, are inclined. When the two adjacent mounting rails 14 are stacked, their first and second mounting sidewalls abut against each other, achieving a seamless connection between the two mounting rails 14.

[0062] Reference Figure 10A first diagonal brace 16 is rotatably connected to the mounting guide rail 14. The connection position between the first diagonal brace 16 and the mounting guide rail 14 is located at one end of the mounting guide rail 14 or at a position where the center point of the mounting guide rail 14 is biased toward one end. When the photovoltaic power generation component 2 is unfolded, the first diagonal brace 16 is rotated until an angle is formed between the first diagonal brace 16 and the mounting guide rail 14, so that the photovoltaic power generation panel 21 works in an inclined state, which is beneficial for the photovoltaic power generation panel 21 to receive sunlight.

[0063] In order to reduce the storage space of the first diagonal brace 16, the mounting guide rail 14 can be set into a "U" shape, and then the rotating shaft of the first diagonal brace 16 can be set in the mounting guide rail 14. When the first diagonal brace 16 is not needed, the first diagonal brace 16 is rotated until the first diagonal brace 16 is completely stored in the mounting guide rail 14, thereby completing the storage of the first diagonal brace 16 and further reducing the storage space of the bracket assembly.

[0064] Reference Figure 7 and Figure 10 When the unfolded photovoltaic power generation component 2 needs to be unfolded for use, first install the photovoltaic panel and the mounting plate 22 on the mounting rail 14, and then install the support component 3 at the end of the mounting rail 14 away from the first diagonal brace 16 and the end of the first diagonal brace 16 away from the mounting rail 14, and use the support component 3 to stably fix the photovoltaic power generation component 2 on the ground.

[0065] Reference Figure 10 The support assembly 3 includes a first base 31, a second base 32, and a gasket 33. The first base 31 is provided with a first mounting hole, into which the end of the mounting rail 14 away from the first diagonal brace 16 is fixed by bolts. The second base 32 is provided with a second mounting hole, into which the end of the first diagonal brace 16 away from the mounting rail 14 is fixed by bolts. Through the first base 31 and the second base 32, the photovoltaic power station can be stably installed on the ground, allowing the photovoltaic power station to stably receive sunlight. The first base 31 and the second base 32 are both provided with a first limiting pattern 34. Correspondingly, one side of the gasket 33 is provided with a second limiting pattern 35 corresponding to the first limiting pattern 34. When the mounting rail 14 is installed on the first base 31 and the first diagonal brace 16 is installed on the second base 32 using bolts, the cooperation between the gasket 33 and the first base 31, and the gasket 33 and the second base 32 can prevent the mounting rail 14 from rotating between the first base 31, and the first diagonal brace 16 and the second base 32, thereby making the entire photovoltaic power station structure stable.

[0066] Reference Figure 7 and Figure 10When multiple photovoltaic power generation components 2 are deployed and used, a pull rod 4 is added between two adjacent first diagonal supports 16, and the two ends of the pull rod 4 are respectively connected to the two adjacent first diagonal supports 16 by bolts, and the two ends of the pull rod 4 are respectively close to the second base 32 and the mounting guide rail 14, that is, the pull rod 4 is installed in an inclined shape between the two first diagonal supports 16, and the two adjacent photovoltaic power generation components 2 are connected by the pull rod 4, thereby forming a continuous photovoltaic power station. The adjacent photovoltaic power generation components 2 are mutually restrained, making the overall structure of the photovoltaic power station more stable and firm, and not easily affected by strong winds.

[0067] When storing, just place the support assembly 3 and the pull rod 4 in the storage cavity for storage.

[0068] Reference Figure 10 A second diagonal brace 17 is rotatably connected to the mounting guide rail 14. The second diagonal brace 17 is located between the first diagonal brace 16 and the first base 31, and the second diagonal brace 17 is also rotatably connected to the mounting guide rail 14. When not needed, the second diagonal brace 17 can be completely stored in the mounting guide rail 14 to save storage space.

[0069] When the photovoltaic power generation assembly 2 needs to be unfolded for use, the first diagonal brace 16 and the second diagonal brace 17 are rotated to form an angle with the mounting guide rail 14, and then the ends of the first diagonal brace 16 and the second diagonal brace 17 away from the mounting guide rail 14 are respectively connected to the second base 32, so that the first diagonal brace 16, the second diagonal brace 17 and the mounting guide rail 14 section between the first diagonal brace 16 and the second diagonal brace 17 form a triangular structure, thereby enhancing the structural stability of the photovoltaic power station.

[0070] The rotation angles between the first diagonal brace 16 and the second base 32 and between the second diagonal brace 17 and the second base 32 can be adjusted according to actual needs, and then the first diagonal brace 16 and the second diagonal brace 17 are fixed to the second base 32 through the gasket 33, thereby ensuring that the angles of the photovoltaic panels 21 of the photovoltaic power station meet the requirements.

[0071] The implementation principle of a portable movable photovoltaic power station in the embodiment of the present application is as follows: when in use, the top cover 13 is opened, the mounting guide rail 14 is taken out from the first slot 121, and then the photovoltaic power generation component 2 is taken out from the box body 1, the photovoltaic power generation panel 21 is clamped in the mounting rail 142, and the mounting plate 22 is clamped in the second slot 143, and then the first diagonal support 16 and the second diagonal support 17 are rotated to form an angle with the mounting guide rail 14, and the end of the mounting guide rail 14 away from the first diagonal support 16 is fixed on the first base 31, and the end of the first diagonal support 16 and the second diagonal support 17 away from the mounting guide rail 14 is fixed on the second base 32, and then the pull rod 4 is fixed on the two adjacent first diagonal supports 16; when storing, the photovoltaic power station is disassembled in reverse according to the installation steps, and the photovoltaic power generation component 2 is placed in the box body 1, and the mounting guide rail 14 is installed back between the two columns 12, so as to obtain a complete box body 1 structure.

[0072] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
