Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage technology, specifically a foldable photovoltaic energy storage system. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic energy storage devices have been widely used as an important solar energy utilization device. They are typically installed outdoors, using solar panels to collect, convert, and store energy.

[0003] However, in existing technologies, most photovoltaic energy storage devices have fixed solar panels after installation. In practical applications, when it is necessary to move and promptly deploy them to provide power, it is difficult to disassemble and deploy them in a timely manner. Examples include clean power supply for oil and gas wells in field construction scenarios, short- to medium-term geological exploration operations (lasting tens of days or even years), uncertain temporary power needs, and temporary photovoltaic power generation and storage systems in disaster relief sites. All of these require power generation and energy storage systems. If fixed-installation photovoltaic energy storage devices are used, the solar panels cannot be quickly disassembled after use. Therefore, there is an urgent need for a technical solution that can flexibly store and protect solar panels to overcome the shortcomings of existing technologies. Utility Model Content

[0004] Therefore, to address the aforementioned shortcomings, this utility model provides a foldable photovoltaic energy storage system. This system, through multiple hinged photovoltaic energy storage panels and track supports, facilitates the flattening or storage of the photovoltaic energy storage panels. This allows for convenient photovoltaic power generation and energy storage operations when flattened, and also facilitates storage and transportation when relocating for further operations. The track fixing components secure the folded photovoltaic energy storage panels, thereby reducing the impact of the external environment on the panels and effectively improving the lifespan and reliability of the photovoltaic energy storage system. Furthermore, this system is simple and quick to fold, making it convenient for manual operation.

[0005] This invention is achieved by constructing a foldable photovoltaic energy storage system, which includes multiple photovoltaic energy storage panels that are hinged together.

[0006] Two track supports are used to place the photovoltaic energy storage panels;

[0007] The photovoltaic energy storage panel is slidably connected to the track support at any end and can be in two states: flat and folded. When the photovoltaic energy storage panel is in the folded state, it is fixed by the track fixing component.

[0008] Preferably, each of the track supports is composed of multiple support arms spliced ​​together. A slide rail is provided at the top of the support arm, the photovoltaic energy storage panel is installed on the slide rail and moves along the slide rail, and connecting plates are provided on both sides of the bottom of the support arm to keep the multiple support arms spliced ​​together and fixed through the connecting plates.

[0010] Preferably, a rod body is provided on the side of the support rod, the roller is rotatably mounted on the outer end of the rod body, and a strip plate is rotatably provided at one end of the outer end of the rod body. The other end of the strip plate has a through hole for the pin to pass through, and the through hole of the strip plate is located below the bottom of the track support.

[0011] Preferably, the track fixing assembly includes a fixing seat and a fixing frame. The fixing seat is installed on the end of the track support, and the fixing frame extends outward from the top of the fixing seat near the side of the track support. Vertically distributed insertion holes are provided at the center of the fixing frame.

[0012] Preferably, the lower end of the photovoltaic energy storage panel is provided with a limiting steel cable for controlling the tilt angle of the photovoltaic energy storage panel. One end of the limiting steel cable is fixed to the top side of the fixing base, and the other end of the limiting steel cable extends to the outermost side of the photovoltaic energy storage panel and remains connected to the photovoltaic energy storage panel.

[0014] Preferably, the fixing component is a storage box, which has an opening on its side and is connected to the end of the track support.

[0015] Preferably, the storage box contains an energy storage module, the energy collected by the photovoltaic energy storage panel is stored in the energy storage module, and AC power is provided to the outside through an inverter.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1.

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0029] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0030] As described in the background section, existing photovoltaic energy storage devices are usually fixed outdoors. If they are to be moved and installed in a timely manner to provide power, they are difficult to disassemble and install in a timely manner, so they are not very practical and cannot meet some outdoor power generation needs.

[0031] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0032] Example 1,

[0033] Please see the appendix Figure 1 ~Appendix Figure 5 A foldable photovoltaic energy storage system includes multiple photovoltaic energy storage panels 4 that are hinged together, and two track supports 3 for placing the photovoltaic energy storage panels 4. Any end of the photovoltaic energy storage panel 4 is slidably connected to the track support 3 and can be in two states: flat and folded. When the photovoltaic energy storage panel 4 is in the folded state, it is fixed by a track fixing component.

[0034] Please refer to the appendix carefully. Figure 5 In this embodiment, each track support 3 is composed of multiple support arms spliced ​​together. A slide rail is provided at the top of the support arm. The photovoltaic energy storage panel 4 is installed on the slide rail and moves along the slide rail. Connecting plates 8 are provided on both sides of the bottom of the support arm. The multiple support arms are spliced ​​together and fixed by the connecting plates 8.

[0035] Please continue to refer to the appendix. Figure 5In this embodiment, one end of the photovoltaic energy storage panel 4 is provided with a roller 10 via a support rod 9. The roller 10 is rotatably mounted on the side of the support rod 9. The roller 10 is locked at both ends of the slide rail and moves linearly along the slide rail direction. The other end of the photovoltaic energy storage panel 4 is hinged to the adjacent photovoltaic energy storage panel 4 via a hinge.

[0036] When energy storage is required, the photovoltaic energy storage panel 4 is pulled outward. The rollers 10 of the photovoltaic energy storage panel 4 move linearly on the slide rail of the track support 3. Since the photovoltaic energy storage panel 4 is hinged to each other, it changes from a vertical state to an inclined or horizontal state during the outward pulling process, thus achieving the flat laying of the photovoltaic energy storage panel 4. When it is necessary to store it, simply push the photovoltaic energy storage panel 4 towards the track fixing component. Since one end of the photovoltaic energy storage panel is equipped with rollers and the other end remains hinged, the horizontal photovoltaic energy storage panel can be converted to a vertical state due to the limitation of the track fixing component during the pushing process, thus achieving storage.

[0037] Example 2,

[0038] Please see the appendix Figure 5 Based on Embodiment 1, in order to improve the stability of the photovoltaic energy storage panel on the track support, a rod body is provided on the side of the support rod 9, the roller 10 is rotatably installed on the outer end of the rod body, and a strip plate 11 is rotatably provided at one end of the outer end of the rod body. The other end of the strip plate 11 is provided with a through hole for the pin to pass through. The through hole of the strip plate 11 is located below the bottom of the track support 3.

[0039] From the appendix Figure 5 As can be seen, there are two track supports 3 arranged in parallel. The bottom of the photovoltaic energy storage panel 4 is provided with two support rods and two rollers. Each support rod is provided with a strip plate 11. When the photovoltaic energy storage panel 4 is in the stored state or laid flat state, a pin is inserted into the through hole of the strip plate 11. The pin passes through the strip plate 11 at the outer end of the two track supports. Since the through hole of the strip plate 11 is lower than the bottom of the track support 3, that is, the pin is at the bottom of the track support 3, the photovoltaic energy storage panel is prevented from being hit by external objects or blown by strong winds, which would cause the rollers to detach from the slide rail on the track support, thereby improving the stability of the photovoltaic energy storage panel 4 on the track support.

[0040] When the photovoltaic energy storage panel is being stored or laid flat, the pins will be limited by the connecting plates on both sides of the bottom of the track support 3. The pins can be removed first to facilitate the movement of the photovoltaic energy storage panel until the photovoltaic energy storage panel is fixed, and then the pins can be inserted again.

[0041] Example 3,

[0042] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 Based on Embodiment 1, in order to fix the folded photovoltaic energy storage panel, a feasible solution is provided here. Specifically, the track fixing assembly includes a fixing seat 1 and a fixing frame 2. The fixing seat 1 is installed on the end of the track support 3. The fixing frame 2 is provided on the side of the fixing seat 1 near the track support 3 and extends outward. The fixing frame 2 has vertically distributed insertion holes at the center.

[0043] In this embodiment, a limiting steel cable 5 for controlling the tilt angle of the photovoltaic energy storage panel 4 is provided at the lower end of the photovoltaic energy storage panel 4. One end of the limiting steel cable 5 is fixed to the top side of the fixing base 1, and the other end of the limiting steel cable 5 extends to the outer side of the outermost photovoltaic energy storage panel 4 and is connected to the photovoltaic energy storage panel 4. The photovoltaic energy storage panel 4 can be kept tilted and fixed by the pull of the limiting steel cable 5, which can effectively prevent the accumulation of dust and snow and realize the self-cleaning of rainwater and wind.

[0044] After the photovoltaic energy storage panel is folded, it is fixed to the fixing frame by a limiting steel cable.

[0045] Example 4,

[0046] Please see the appendix Figure 3 and attached Figure 4 Based on embodiment 3, in order to improve the stability of the folded photovoltaic energy storage panel, when the photovoltaic energy storage panel 4 is in the storage state, an insertion rod 7 is inserted into the insertion hole of the fixing frame 2, and the bottom of the insertion rod 7 extends downward to the lower side of the outermost photovoltaic energy storage panel 4.

[0047] In this embodiment, the limiting steel cable in Example 3 and the insertion rod in Example 4 can be used alone or in combination. The limiting steel cable stabilizes the folded photovoltaic energy storage panel, making it easier for subsequent workers to pull it out and lay it flat. However, the limiting steel cable is not easy to place and can easily trip workers. On the other hand, the insertion rod stabilizes the folded photovoltaic energy storage panel, making it easier for workers to operate. However, the insertion rod is easy to lose after being removed. The two solutions each have their advantages and disadvantages, and the choice should be made according to actual needs.

[0048] Example 5,

[0049] Please see the appendix Figure 6 Based on Embodiment 1, in order to fix the folded photovoltaic energy storage panel, another feasible solution is provided. Specifically, the fixing component is a storage box 6, which has an opening on its side and is connected to the end of the track support 3.

[0050] In this embodiment, an energy storage module 12 is placed inside the storage box. The energy storage module 12 can be configured as a battery. The energy collected by the photovoltaic energy storage panel is stored in the energy storage module 12 and provided to the outside through an inverter.

[0051] By setting the fixing component in the embodiment as a storage box, the folded photovoltaic energy storage panel can be stored in the box space, thereby avoiding being rained on. At the same time, the energy storage module placed in the storage box can continuously supply power to the external processing equipment, avoiding power outages to the external processing equipment and production disruptions caused by the photovoltaic energy storage panel not working at night or in severe weather conditions.

[0052] All components in this technical solution, except for the photovoltaic energy storage panel, can be made of steel, which has high strength and is not afraid of harsh weather.

[0053] In this technical solution, the photovoltaic energy storage panel 4 generates a safe voltage of less than 120V through photovoltaics. At the same time, the photovoltaic energy storage panel 4 has a steel back plate, which can be walked on after installation and is resistant to hail.

[0054] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
