Description

Technical Field

[0001] This utility model relates to the field of off-grid power station technology, and in particular to an automatic folding component system for off-grid power stations. Background Technology

[0002] To achieve carbon neutrality and peak carbon emissions, the country has vigorously developed clean energy in recent years, such as hydropower, wind power, and solar power. Among these, solar power is the most important clean energy source, and photovoltaic (PV) modules are the medium for converting solar energy into electricity. A grid-connected PV power station refers to a photovoltaic power generation system that utilizes solar energy, employs special materials such as crystalline silicon panels, inverters, and other electronic components, and is connected to the power grid to transmit electricity to it.

[0003] In some regions, due to inconvenient transportation or geographical limitations, it is generally difficult to achieve rapid power supply in a short period of time. Existing off-grid power stations are generally steel structure portal frames or fixed supports, which are difficult to transport in remote areas, involve many types of materials, and have a long cycle from component installation to power generation. Therefore, we propose an automatic folding component system for off-grid power stations. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: an automatic folding assembly system for off-grid power stations, comprising:

[0005] A shipping container has a fixed block on its top, a motor at its bottom, a drive wheel on one side of the motor, a first transmission wheel on its inner wall, a drive shaft on the inner side of the first transmission wheel, the drive wheel meshing with the drive shaft, a limit frame inside the container, a steel strand running through the side wall of the limit frame, a side frame on the side wall of the container that does not contact the container, the side of the steel strand away from the container connected to the side frame, a second transmission wheel on the side wall of the side frame, a drive belt on the outer ring of the second and first transmission wheels, and a foldable photovoltaic module on the inner side of the steel strand connected to the drive belt.

[0006] As an improvement to the above technical solution, the top of the side frame is provided with a hook to catch the steel strand.

[0007] As an improvement to the above technical solution, a limiting sleeve is provided on the side wall of the limiting frame, and the limiting sleeve is located on the outer ring of the steel strand.

[0008] As an improvement to the above technical solution, an energy storage box is provided at the bottom of the inner wall of the container, and an inverter is provided on the inner wall of the container.

[0009] As an improvement to the above technical solution, the side of the foldable photovoltaic module away from the container is fixedly connected to the transmission belt, the side of the foldable photovoltaic module close to the container is slidably connected to the transmission belt, and the foldable photovoltaic module and the steel strand are detachably installed.

[0010] As an improvement to the above technical solution, the foldable photovoltaic module is provided in two sets, and the inner side of the two sets of foldable photovoltaic modules is provided with a limit rope.

[0011] The beneficial effects of this utility model are:

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0019] Please see Figure 1-3 An automatic folding assembly system for off-grid power plants includes:

[0020] Container 1 has a fixed block 3 on its top, a motor 4 at the bottom of the fixed block 3, a drive wheel 5 on one side of the motor 4, a first transmission wheel 7 on the inner wall of the container 1, a drive shaft 6 on the inner side of the first transmission wheel 7, the drive wheel 5 meshing with the drive shaft 6, a limit frame 11 inside the container 1, a steel strand 13 running through the side wall of the limit frame 11, a side frame 2 on the side wall of the container 1, the side frame 2 not in contact with the container 1, the side of the steel strand 13 away from the container 1 connected to the side frame 2, a second transmission wheel 16 on the side wall of the side frame 2, a drive belt 8 on the outer ring of the second transmission wheel 16 and the first transmission wheel 7, and a foldable photovoltaic module 9 on the inner side of the steel strand 13 connected to the drive belt 8.

[0021] The start motor 4 causes the drive wheel 5 to rotate. The drive wheel 5 meshes with the drive shaft 6, causing the drive shaft 6 to rotate, which in turn causes the first drive wheel 7 to rotate. This drives the drive belt 8 and the second drive wheel 16 to rotate. At this time, the drive belt 8 will drive the foldable photovoltaic module 9 to slide on the outer ring of the steel strand 13, thus unfolding and retracting the foldable photovoltaic module 9. The motor 4 drives the drive belt 8 through the drive wheel by rotating forward and backward, thereby realizing the folding and unfolding of the module. The device has an extremely fast installation cycle, automatic folding and unfolding of the module, centralized storage, and modular assembly.

[0022] The top of the side frame 2 is equipped with a hook to catch the steel strand 13.

[0023] The hook on the side frame 2 hooks the steel strand 13, straightening the steel strand 13, and the transmission belt 8 drives the foldable photovoltaic module 9 to slide on the outside of the steel strand 13.

[0024] The side wall of the limiting frame 11 is provided with a limiting sleeve 12, which is located on the outer ring of the steel strand 13.

[0025] When the foldable photovoltaic module 9 is retracted, the limiting frame 11 can limit the movement of the foldable photovoltaic module 9. During the process of the transmission belt 8 driving the foldable photovoltaic module 9 to move, the limiting frame 11 limits the movement and can block the foldable photovoltaic module 9, thereby allowing the foldable photovoltaic module 9 to be retracted.

[0026] An energy storage box 15 is installed at the bottom of the inner wall of container 1, and an inverter 14 is installed on the inner wall of container 1.

[0027] The device converts the DC power generated by the foldable photovoltaic module 9 through the inverter 14 and stores the electrical energy through the energy storage box 15.

[0028] The side of the foldable photovoltaic module 9 furthest from the container 1 is fixedly connected to the transmission belt 8, while the side of the foldable photovoltaic module 9 closest to the container 1 is slidably connected to the transmission belt 8. The foldable photovoltaic module 9 and the steel strand 13 are detachable and installable.

[0029] The side of the foldable photovoltaic module 9 furthest from the container 1 is fixedly connected to the transmission belt 8, while the side of the foldable photovoltaic module 9 closest to the container 1 is slidably connected to the transmission belt 8. During the rotation of the transmission belt 8, one side of the foldable photovoltaic module 9 slides along the outer ring of the transmission belt 8, while the other side moves fixedly to the transmission belt 8. Limiting is achieved by the limiting frame 11. Furthermore, the side wall of the foldable photovoltaic module 9 is equipped with pulleys. During the rotation of the transmission belt 8, the pulleys slide along the steel strand 13, enhancing stability during sliding. The side wall of the foldable photovoltaic module 9 is also equipped with threaded locking blocks. After sliding the foldable photovoltaic module 9 along the steel strand 13, the side wall of the foldable photovoltaic module 9 can be locked into the locking blocks, and then fixed and limited by the threaded connection of bolts. The foldable photovoltaic module 9 can be disassembled from the steel strand 13 by the threaded connection of the bolts, allowing it to be unfolded and retracted.

[0030] The foldable photovoltaic module 9 is provided in two sets, and the inner side of the two sets of foldable photovoltaic modules 9 is provided with a limit rope 10.

[0031] The position of the foldable photovoltaic module 9 is limited by the limiting rope 10. When the motor 4 is started, the transmission belt 8 rotates, which drives the foldable photovoltaic module 9 to move. One end of the foldable photovoltaic module 9 is fixed and the other end is slidable. During the movement of the foldable photovoltaic module 9, the sliding side of the foldable photovoltaic module 9 is stretched and unfolded by the limiting rope 10.

[0032] When the device needs to be unfolded, the side frame 2 inside the container 1 is removed and fixed in a suitable position. Then, the motor 4 is started to make the drive wheel 5 rotate. The drive wheel 5 meshes with the drive shaft 6, causing the drive shaft 6 to rotate, which in turn causes the first drive wheel 7 to rotate, driving the drive belt 8 and the second drive wheel 16 to rotate. At this time, the drive belt 8 will drive the foldable photovoltaic module 9 to move. Since the side of the foldable photovoltaic module 9 away from the container 1 is fixedly connected to the drive belt 8, and the side of the foldable photovoltaic module 9 close to the container 1 is slidably connected to the drive belt 8, the side of the foldable photovoltaic module 9 away from the container 1 moves with the drive belt 8 during the movement of the drive belt 8. The side of the foldable photovoltaic module 9 close to the container 1 slides on the outer ring of the drive belt 8. At this time, due to the action of the limiting rope 10, the two sets of foldable photovoltaic modules 9 are stretched and unfolded. After the foldable photovoltaic modules 9 are stretched and unfolded, they are installed in the steel strand 13 for fixation, making them convenient for use. They can be converted by the inverter 14 and stored by the energy storage box 15.

[0033] When retraction is required, the foldable photovoltaic module 9 is first removed from the steel strand 13. Then, the motor 4 is started to reverse, causing the device to reverse. During the rotation of the transmission belt 8, the foldable photovoltaic module 9 is moved. When the side of the foldable photovoltaic module 9 close to the container 1 approaches the limit frame 11, the foldable photovoltaic module 9 is stuck, while the transmission belt 8 continues to rotate. The side of the foldable photovoltaic module 9 away from the container 1 continues to rotate with the transmission belt 8, which can cause the foldable photovoltaic module 9 to retract. After the foldable photovoltaic module 9 is retracted, the side frame 2 is put into the container 1, realizing the folding and retraction of the device. The installation cycle of the device is extremely fast, the components fold and unfold automatically, and it is centrally stored and modularly assembled.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
