Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, specifically to a building-integrated photovoltaic energy storage device. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is an innovative model that combines photovoltaic power generation technology with architectural design. This model integrates solar cell modules directly into the external structure of a building, such as the roof, walls, and windows, achieving a combination of aesthetics and functionality. Energy storage equipment is an important component in the construction of BIPV systems, capable of storing the electrical energy generated by the photovoltaic power generation system for use when needed. This equipment typically works in coordination with other system components such as photovoltaic modules, inverters, and energy storage systems, effectively improving the overall performance and energy efficiency of the photovoltaic system. Existing photovoltaic modules are mostly installed on building rooftops. Over time, their surfaces accumulate a lot of dust and impurities. Without effective cleaning, this can affect the energy storage performance of the photovoltaic modules.

Each photovoltaic mechanism 4 includes two symmetrically distributed photovoltaic modules 6, and a first flipping component 7 is provided between two photovoltaic modules 6. According to the construction length of the BIPV, an appropriate number of photovoltaic mechanisms 4 are installed. In one of the photovoltaic mechanisms 4, the bottom of the photovoltaic module 6 is fixedly mounted on the building through the mounting frame 1, and the protective component 3 is installed on the bottom of the photovoltaic module 6 on the side away from the mounting frame 1. The photovoltaic module 6 includes a module frame 61. A photovoltaic panel 62 is fixedly installed in the middle of the module frame 61.

In use, the threaded rod 631 is controlled to rotate, which drives the horizontal slide frame 63 to slide horizontally in the horizontal slide groove 601, thereby driving the fixing frame 64 and the cleaning scraper frame 65 to slide on the surface of the photovoltaic panel 62. The cleaning fluid is introduced into the cleaning scraper frame 65 through the connector 653 and the connecting pipe 652, and is evenly sprayed out through multiple spray holes 651 onto the surface of the photovoltaic panel 62 to clean impurities on the surface of the photovoltaic panel 62, preventing impurities from adhering to the surface of the photovoltaic panel 62 and affecting the light conversion effect of the photovoltaic panel 62, thereby improving the overall performance of the photovoltaic energy storage device.

In use, the first motor 742 is turned on to drive the first worm 741 to drive the first worm wheel 74 to rotate, thereby driving the first auxiliary shaft 73 and the corresponding first flip shaft 711 to rotate. Since the two first gears 72 are meshed and connected, they drive the other first flip shaft 711 to rotate synchronously in the opposite direction. This controls the two sets of first frames 712 to rotate synchronously in the opposite direction relative to the first rotating frame 71, thereby controlling the two photovoltaic modules 6 in each photovoltaic mechanism 4 to rotate synchronously in the opposite direction, thus folding the two photovoltaic modules 6 in each photovoltaic mechanism 4 and protecting the photovoltaic modules 6.

[0033] A first protective cover 75 is fixedly installed on the outer side of the first rotating frame 71. The first gear 72, the first auxiliary shaft 73, the first worm gear 74, the first worm 741 and the first motor 742 are located in the first protective cover 75. By setting the first protective cover 75, the first gear 72, the first auxiliary shaft 73, the first worm gear 74, the first worm 741 and the first motor 742 are protected.

[0034] The opposite ends of the threaded rods 631 in the two photovoltaic modules 6 extend out of the outer side of the corresponding module frame 61. A transmission gear 632 is fixedly installed on the opposite ends of the threaded rods 631 in both photovoltaic modules 6. An arc-shaped frame 633 is provided on the side of the first frame 712 near the transmission gear 632. An arc-shaped rack 634 is provided on the top of the arc-shaped frame 633 to cooperate with the transmission gear 632. The transmission gear 632 can mesh with the arc-shaped rack 634. The arc-shaped frame 633 is fixedly installed on the corresponding first rotating frame 71. The center position of the arc-shaped frame 633 corresponds to the axis position of the corresponding first flip shaft 711. When the two photovoltaic modules 6 in each photovoltaic mechanism 4 are folded, the arc-shaped rack 634 is fixed relative to the first rotating frame 71, the transmission gear 632 rotates relative to the first rotating frame 71, and the transmission gear 632 and the arc-shaped rack 634 mesh with each other. The arc-shaped rack 634 drives the transmission gear 632 and the threaded rod 631 to rotate synchronously.

[0035] The second flipping component 5 includes two symmetrically distributed second rotating frames 51. Two symmetrically distributed second flipping shafts 511 are rotatably mounted between the two second rotating frames 51. A second frame 512 is fixedly mounted at both ends of each second flipping shaft 511. The second frames 512 are respectively fixedly mounted on the outer frame 61 of the corresponding photovoltaic mechanism 4.

The second motor 533 is fixedly installed on the side of the second rotating frame 51 near the second worm 532.

When in use, the second motor 533 is turned on to drive the second worm 532 to drive the second worm wheel 531, the second auxiliary shaft 53, and the corresponding second flip shaft 511 to rotate. Since the two second gears 52 are meshed and connected, they drive the other second flip shaft 511 to rotate synchronously in the opposite direction. This controls the two sets of second frames 512 to rotate synchronously in the opposite direction relative to the second rotating frame 51, thereby controlling the synchronous reverse folding and rotation of two adjacent photovoltaic mechanisms 4 in the photovoltaic equipment 2, realizing the folding protection of multiple photovoltaic modules 6.

[0036] A second protective cover 54 is fixedly installed on the outside of the second rotating frame 51. The second gear 52, the second auxiliary shaft 53, the second worm gear 531, the second worm 532, and the second motor 533 are located in the second protective cover 54. The second protective cover 54 is used to protect the second gear 52, the second auxiliary shaft 53, the second worm gear 531, the second worm 532, and the second motor 533.

When the multiple photovoltaic modules 6 are folded, the cleaning fluid output system is opened simultaneously, and the cleaning fluid is introduced into the connectors 653 on the corresponding photovoltaic module 6 through the liquid guiding hoses 82, the three-way pipes 81, and the connecting hoses 8.

[0038] The photovoltaic device 2 is fixedly installed on the top of the mounting frame 1 via the outer frame 61 of the corresponding photovoltaic module 6.

[0039] The protective component 3 includes a protective plate 31, with inclined guide plates 32 fixedly installed around its perimeter. A buffer element 33 is provided between the protective plate 31 and the corresponding component outer frame 61, and the buffer element 33 has multiple evenly distributed components. The buffer element 33 includes a buffer top frame 331, and a buffer bottom frame 332 at its bottom end. A limiting ring 333 is fixedly engaged at the bottom end of the buffer top frame 331, and the buffer bottom frame 332 movably passes through the limiting ring 333. A positioning ring 334 is fixedly installed at the top of the buffer bottom frame 332, and the positioning ring 334 is slidably engaged within the buffer top frame 331. Between the buffer top frame 331 and the buffer bottom frame 332... A shock absorber 335 is provided. The protective component 3 is fixedly clipped to the corresponding component outer frame 61 via a buffer top frame 331. The protective component 3 is fixedly installed on the protective plate 31 via a buffer bottom frame 332. After multiple photovoltaic modules 6 are folded and stored, the protective component 3 is located at the top. In rainy or snowy weather, the protective plate 31 and the surrounding inclined guide plates 32 protect the multiple folded photovoltaic modules 6. In hail weather, the hail falls on the protective plate 31 and impacts it. The shock absorber 335 absorbs the shock, thereby protecting the multiple folded photovoltaic modules 6 from impact damage and improving the overall performance of the photovoltaic energy storage device.

[0040] Working principle: When in use, according to the construction length of the building-integrated photovoltaics, a suitable number of photovoltaic mechanisms 4 are installed. In one of the photovoltaic mechanisms 4, the bottom end of the photovoltaic module 6 is fixedly installed on the building through the mounting frame 1, and the protective component 3 is installed on the bottom end of the photovoltaic module 6 on the side away from the mounting frame 1. The end of the liquid guiding hose 82 is connected to the output port of the cleaning liquid output system. Multiple photovoltaic modules 6 are unfolded, and the photovoltaic panel 62 performs light energy conversion and transmission. When encountering rain, snow, or hail, or when the surface of the photovoltaic panel 62 needs to be cleaned, the first motor 742 can be turned on to drive the first worm gear 741 to drive the first worm wheel 74 to rotate, thereby driving the first auxiliary shaft 73 and the corresponding first flip shaft 711 to rotate. Since the two first gears 72 are meshed and connected, they drive the other first flip shaft 711 to rotate synchronously in the opposite direction, thereby controlling the two sets of first frames 712 to rotate synchronously in the opposite direction relative to the first rotating frame 71, thereby controlling the two photovoltaic modules 6 in each photovoltaic mechanism 4 to rotate synchronously in the opposite direction, thereby folding the two photovoltaic modules 6 in each photovoltaic mechanism 4 and protecting the photovoltaic modules 6. When the two photovoltaic modules 6 in each photovoltaic mechanism 4 are folded, the arc-shaped rack 634 is fixed relative to the first rotating frame 71, and the transmission gear 632 rotates relative to the first rotating frame 71. The transmission gear 632 and the arc-shaped rack 634 are meshed and connected. The arc-shaped rack 634 drives the transmission gear 632 and the threaded rod 631 to rotate synchronously, which drives the transverse slide frame 63 to slide in the transverse slide groove 601. This causes the fixed frame 64 and the cleaning scraper frame 65 to slide on the surface of the photovoltaic panel 62. At the same time, the cleaning fluid output system is turned on. The cleaning fluid is introduced into the connector 653 on the corresponding photovoltaic module 6 through the liquid guiding hose 82, the three-way pipe 81, and the connecting hose 8. The cleaning fluid is introduced into the cleaning scraper frame 65 through the connector 653 and the connecting pipe 652, and is evenly sprayed out through multiple spray holes 651 onto the surface of the photovoltaic panel 62 to clean the surface of the photovoltaic panel 62 and prevent impurities from adhering to the surface of the photovoltaic panel 62, which would affect the light conversion effect of the photovoltaic panel 62. This improves the overall performance of the photovoltaic energy storage device. Simultaneously, the first motor 742 is activated to drive the first worm gear 741 to rotate the first worm wheel 74, thereby driving the first auxiliary shaft 73 and the corresponding first flip shaft 711 to rotate. Since the two first gears 72 are meshed and connected, they drive the other first flip shaft 711 to rotate synchronously in the opposite direction. This controls the two sets of first frames 712 to rotate synchronously in the opposite direction relative to the first rotating frame 71, thereby controlling the two photovoltaic modules 6 in each photovoltaic mechanism 4 to rotate synchronously in the opposite direction, thus folding the two photovoltaic modules 6 in each photovoltaic mechanism 4 and protecting the photovoltaic modules 6. After multiple photovoltaic modules 6 are folded and stored, the protective component 3 is located at the top. In rainy or snowy weather, the protective plate 31 and the surrounding inclined guide plates 32 protect the multiple folded photovoltaic modules 6. In hail weather, the hail falls on the protective plate 31 and impacts it. The shock absorber 335 absorbs the shock, thus protecting the multiple folded photovoltaic modules 6 from impact damage and improving the overall performance of the photovoltaic energy storage device.
