Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a mobile, ultra-large integrated photovoltaic and energy storage power compartment. Background Technology

[0002] Currently, to address the issue of high-power electricity consumption in outdoor activities or remote areas, products using large shipping containers to carry photovoltaic power generation systems have emerged. These products are characterized by their portability and ability to supply high-power electricity. The photovoltaic systems in these products primarily use crystalline silicon modules or conventional rollable modules. The module arrays are installed in two ways: one is by directly fixing the modules to the top or sides of the container; the other is by stacking and storing the modules in large quantities inside the container. When used for power generation in the field, the modules are pushed out of the container and laid on the ground using fixing devices and support rails.

[0003] Existing technologies generally employ the following techniques:

[0004] One type of product involves directly fixing crystalline silicon modules or rollable modules onto the top, sides, or surface of the extended support structure of a container. The module installation area is small, the installed capacity is relatively small, and adding support mechanisms inside the container will increase the cost and weight of the container.

[0005] Another type of product stacks and stores the modules inside a container. When used for power generation in the field, the modules are pushed out of the container and laid on the ground using fixing devices and support rails. While this type of product can increase photovoltaic installation capacity, the large number of modules occupies a significant portion of the container's internal space, compressing the space available for installing the integrated energy storage and control system, thus resulting in a relatively small energy storage capacity. Furthermore, the modules are heavy, and the supporting structure needs to be robust and reliable to ensure load-bearing capacity, further increasing the overall weight of the product. In addition, pushing this type of product out of the container or storing it from the outside requires manual labor, demanding multiple people and is inconvenient. If a powered automatic pushing and storing system is used, the system requires high power, is heavy, and is costly.

[0006] Most containerized photovoltaic products use ordinary crystalline silicon modules. When containers are transported on complex terrain in the field, if they are frequently subjected to large bumps or vibrations, the solar cells may have hidden cracks. Utility Model Content

[0007] Therefore, this utility model provides a movable, ultra-large integrated photovoltaic and energy storage power compartment to solve the problems existing in the above-mentioned technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A mobile, ultra-large integrated photovoltaic and energy storage power module includes:

[0010] The housing has side holes on its two side walls for pulling out or retracting the photovoltaic modules;

[0011] A winding mechanism is located inside the housing at positions corresponding to the side holes and the tail section, and is used to wind up the photovoltaic modules.

[0012] A photovoltaic module, wherein the photovoltaic module is made of flexible material and has a sheet-like structure, one side of the photovoltaic module is fixedly connected to a winding mechanism, and the photovoltaic module is wound up on the winding mechanism;

[0013] An integrated energy storage and control system is fixedly connected inside the enclosure and electrically connected to the photovoltaic module.

[0014] A side door is provided at a position on the side wall of the box corresponding to the side hole. The size of the side door is at least not smaller than the size of the side hole, and the top of the side door is hinged to the box.

[0015] Optionally, multiple side holes are spaced horizontally, and a winding mechanism is arranged parallel to each side hole in the housing.

[0016] Optionally, the winding mechanism includes a fixed base, which is fixedly connected to the bottom of the inner wall of the box, and a winding shaft is rotatably connected to the top of the fixed base. A motor is provided at one end of the winding shaft, and the output end of the motor is coaxially and fixedly connected to the winding shaft. The motor is fixedly connected to the fixed base, and one side of the photovoltaic module is fixedly connected to the winding shaft.

[0017] Optionally, a sealing ring is provided around the periphery of the side door.

[0018] Optionally, the system also includes an air conditioner, which is mounted on one of the side walls of the enclosure and is electrically connected to the integrated energy storage and control system.

[0019] Optionally, it also includes a telescopic component, which is disposed inside the housing and between the winding component and the side wall of the housing. The fixed section of the telescopic component is fixedly connected to the inner wall of the housing, and the movable end of the telescopic component is fixedly connected to the side of the photovoltaic module away from the winding shaft. The telescopic component extends and retracts, and works with the motor to drive the winding shaft to complete the unwinding of the photovoltaic module.

[0020] Optionally, the photovoltaic module is made of crystalline silicon, OPV, copper indium gallium, or perovskite.

[0021] This utility model has at least the following beneficial effects:

[0022] This invention utilizes side holes on the side wall of the container and a winding mechanism inside the container corresponding to the side holes. The flexible photovoltaic modules wound on the winding mechanism can extend out of the container through the side holes and unfold to be laid on the ground, thereby reducing the space occupied by the photovoltaic modules and providing more space, i.e., greater electrical capacity, for the integrated energy storage and control system inside the container. At the same time, the winding mechanism can prevent the photovoltaic modules from developing microcracks during the movement of the container. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] like Figures 1-11 As shown, this utility model discloses a flexible rollable photovoltaic module 4 power supply system container, comprising:

[0042] Box 1, with side holes 2 on its two side walls for pulling out or retracting photovoltaic module 4;

[0043] The winding mechanism 3 is located inside the container 1 at positions corresponding to the side opening 2 and the tail door (the door attached to the container) and is used to wind up the photovoltaic module 4.

[0044] Photovoltaic module 4, wherein the photovoltaic module 4 is made of flexible material and has a sheet structure, one side of the photovoltaic module 4 is fixedly connected to the winding mechanism 3, and the photovoltaic module 4 is wound up on the winding mechanism 3;

[0045] An integrated energy storage and control system 5 is fixedly connected inside the housing 1 and is electrically connected to the photovoltaic module 4.

[0046] Side door 7 is located on the side wall of the box 1 at a position corresponding to the side hole 2. The size of the side door 7 is at least not smaller than the size of the side hole 2, and the top of the side door 7 is hinged to the box 1.

[0047] The aforementioned container 1 serves as the outer shell of the entire product. It can be customized or modified from a regular container: openings are made on the side of the container 1, namely the side openings 2 of the container 1. Inside the container, a winding mechanism 3 is fixed at specific points near the long side and the tail to extend and store the flexible photovoltaic module 4. The integrated energy storage and control system 5 is installed inside the container 1, and the energy storage module is electrically connected to the photovoltaic module 4.

[0048] The photovoltaic module 4 mentioned above can specifically be a flexible rollable module made of copper indium gallium selenide, a perovskite flexible rollable module, or an OPV (organic photovoltaic material) flexible rollable module. It can also be an integral flexible rollable module made of crystalline silicon material connected in series. The strips can be connected with a flexible substrate and conductive adhesive. The whole roll can be wound up and unfolded to form a large-area module.

[0049] The photovoltaic module 4 can be unwound by manually pulling the movable end of the photovoltaic module 4 in conjunction with the winding mechanism 3. Alternatively, when it is difficult to unwound manually, tools such as pulley carts can be used for winding.

[0050] In one specific embodiment, the side holes 2 are arranged at multiple intervals in the horizontal direction, and a winding mechanism 3 is arranged parallel to each side hole 2 in the box body 1.

[0051] The side hole 2 can be selected according to actual needs. It can be a whole long strip side hole 2 set on the side wall of the housing 1, or multiple side holes 2 with smaller intervals can be set. Correspondingly, the whole side hole 2 can be a photovoltaic module 4 with a length corresponding to it, or multiple shorter photovoltaic modules 4.

[0052] In one specific embodiment, the winding mechanism 3 includes a fixed base 31, which is fixedly connected to the bottom of the inner wall of the housing 1, and a winding shaft 32 is rotatably connected to the top of the fixed base 31. A motor 33 is provided at one end of the winding shaft 32, and the output end of the motor 33 is coaxially and fixedly connected to the winding shaft 32. The motor 33 is fixedly connected to the fixed base 31, and one side of the photovoltaic module 4 is fixedly connected to the winding shaft 32.

[0053] The aforementioned fixed base 31 is fixedly installed on the bottom of the inner wall of the housing 1. For example, when the fixed base 31 is made of metal, it can be fixed by welding. The two ends of the winding shaft 32 are fixedly connected to the fixed base 31 through bearings, so that the winding shaft 32 can rotate on the fixed base 31. A motor 33 is set at one end of the winding shaft 32. The output end of the motor 33 is coaxially fixedly connected to the winding shaft 32 through a coupling, so that the rotation of the motor 33 can drive the winding shaft 32 to rotate. To wind up the photovoltaic module 4, one side wall of the photovoltaic module 4 (which is adapted to the side hole 2) can be fixed on the winding shaft 32. The photovoltaic module 4 can be wound up by rotating the winding shaft 32.

[0054] In a further embodiment, a sealing ring is provided around the side door 7.

[0055] By setting a sealing ring on the side door 7, the sealing ring can be a weather-resistant and elastic sealing ring, which can have a new sealing and heat preservation effect after the photovoltaic module 4 is retracted into the box 1.

[0056] In a further embodiment, an air conditioner 6 is also included, which is disposed on one of the side walls of the housing 1 and is electrically connected to the integrated energy storage and control system 5.

[0057] Since this application uses a large-capacity energy storage and control integrated system 5, if the outdoor working environment of the container is in an extreme temperature (too hot or too cold), in order to ensure the service life and performance of the battery, an industrial air conditioner 6 is installed inside the container to ensure that the working environment of the energy storage and control integrated system 5 is suitable.

[0058] In some other embodiments, a telescopic component is also included. The telescopic component is disposed inside the housing 1 and is positioned between the winding component and the side wall of the housing 1. The fixed section of the telescopic component is fixedly connected to the inner wall of the housing 1, and the movable end of the telescopic component is fixedly connected to the side of the photovoltaic module 4 away from the winding shaft 32. The telescopic component extends and retracts, and works with the motor 33 to drive the winding shaft 32 to complete the unwinding of the photovoltaic module 4.

[0059] The aforementioned telescopic components enable the automatic winding of the photovoltaic module 4. Specifically, the telescopic components can be a shear-type telescopic frame 8 or a sleeve-type telescopic frame 9.

[0060] The photovoltaic module 4 of this application extends and expands, and for supporting large-size flexible modules, lightweight metal brackets are used. These include, but are not limited to, scissor-type support brackets 9 and multi-layer sleeve-type support brackets 11. These types of support brackets are characterized by their light weight, large support area when extended, and small space occupation when retracted. Furthermore, the deployment and retraction of the brackets can be designed to be automatic or manual, depending on the characteristics of different products. Automatic extension and retraction of the support brackets can be achieved by configuring a power unit and auxiliary mechanical components. The advantage of this method is that it facilitates outdoor work for product users, saving time and effort. The disadvantage is that the additional power unit and auxiliary components occupy space within the housing 1. Manually assisted extension and retraction of the support brackets means that the deployment or retraction of the brackets is done manually. The advantage of this method is that it saves space occupied by the support system within the housing 1. The disadvantage is that it is relatively time-consuming and labor-intensive for users to work outdoors.

[0061] The containerized photovoltaic power supply system uses large-size rollable flexible photovoltaic modules 4 (including, but not limited to, copper indium gallium selenide flexible rollable modules, perovskite flexible rollable modules, OPV flexible rollable modules, crystalline silicon flexible rollable modules, and other types of flexible rollable modules) wound on a rotatable winding shaft 32. When generating electricity outdoors, the flexible modules are unrolled from the winding shaft 32 and pulled out of the container to be laid on the outdoor ground (a simple support frame is fixed to the ground, and then the flexible modules are fixed on the support frame). This container has the following advantages: high power installed capacity, light weight of photovoltaic modules 4, small space occupation inside the container (large installation space for energy storage and control integrated system 5 and control system, which can increase energy storage capacity), no hidden crack risk of flexible rollable module chips, and easy deployment and storage of containerized outdoor modules.

[0062] 1. The photovoltaic module 4 of this product adopts an ultra-large flexible rollable solar module. The area of ​​a single flexible module wound on each winding shaft 32 can reach tens or hundreds of square meters. The flexible module is thin and light, so even though the module area is large, the weight is light. This ensures that the product can provide high-power electricity while the photovoltaic power supply system does not significantly increase the weight of the overall product.

[0063] 2. The components are wound onto a rotatable winding shaft 32 and stored inside the container. The flexible, rollable photovoltaic modules 4 are thin and light, taking up little container space.

[0064] 3. The components can be extended or stored easily via the winding shaft 32;

[0065] 4. Flexible and rollable modules can be transported outdoors without risk of microcracks in the module cells, even if they are subjected to bumps and vibrations for a long time.

[0066] 5. This product extends and unfolds, using lightweight metal brackets to support large-sized flexible components. These include, but are not limited to, scissor-type support brackets and multi-layer sleeve support brackets. These types of support brackets are characterized by their light weight, large support area when extended, and small space occupation when retracted. Furthermore, the expansion and contraction of the brackets can be designed to be automatic or manual, depending on the characteristics of different products. Automatic expansion and contraction of the support bracket can be achieved by configuring a power unit and auxiliary mechanical components. The advantage of this method is that it facilitates outdoor work for the product user, saving time and effort. The disadvantage is that the additional power unit and auxiliary components occupy space within the housing 1. Manually assisted expansion and contraction of the support bracket means that the expansion or contraction of the bracket is done manually. The advantage of this method is that it saves space occupied by the support system within the housing 1. The disadvantage is that it is relatively time-consuming and labor-intensive for users working outdoors.

[0067] The electrical appliances inside the container are powered by an integrated energy storage and control system.

[0068] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0069] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0070] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application.
