Detailed implementation manners

[0019] The technical solutions of the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The components of the embodiments of the present application usually described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] As Figures 1 - 12 shown, the modular and expandable integrated device of photovoltaic solar energy and energy storage proposed by the present invention includes a bottom plate 1. A support frame 2 is fixedly connected to the top end of the bottom plate 1. An installation box 3 is fixedly connected to the top end of the support frame 2. A photovoltaic panel 4 is fixedly connected to the top end of the installation box 3. An energy storage box 5 is fixedly connected to the top end of the bottom plate 1. It further includes a protection component for protecting the surface of the photovoltaic panel 4 in sandy and windy weather. The protection component includes a wind power structure, a transmission structure, and an enclosure structure.

[0025] To solve the problem of damage to the surface of the photovoltaic panel 4 in an environment with more sand and wind, when using the photovoltaic solar power generation device, the photovoltaic panel 4 can convert light energy into electrical energy and transfer the electrical energy into the energy storage box 5 for storage. Multiple modularly arranged photovoltaic panels 4 are installed in the installation box 3, which is beneficial to the installation and replacement of the photovoltaic panels 4. By setting the wind power structure, the strong wind in the desert environment can be utilized for power generation. By setting the transmission structure, the kinetic energy generated by the wind power structure can be transferred to the enclosure structure. Through the enclosure structure, in strong desert wind weather, the surface of the photovoltaic panel 4 can be enclosed by the first sealing plate 24 and the second sealing plate 25, which can protect the surface of the photovoltaic panel 4 and prevent the sand and gravel in the strong wind from damaging the surface of the photovoltaic panel 4.

[0026] As Figure 7, the wind power structure is used to utilize the wind flow in sandy weather. The wind power structure includes an impeller 8, and the impeller 8 is arranged on the top of the installation box 3. The wind power structure further includes a wind hood 9, and the wind hood 9 is fixedly connected to the top end of the installation box 3. A collection port is arranged on one side of the wind hood 9 close to the photovoltaic panel 4. The impeller 8 is arranged inside the wind hood 9. A rotating rod 7 is fixedly connected to the center of the impeller 8. A rotating generator 6 is fixedly connected to the top end of the bottom plate 1. The rotating rod 7 is fixedly connected to the drive shaft of the rotating generator 6. The rotating generator 6 is connected to the energy storage box 5 through a transmission line.

[0027] In case of strong wind weather, the wind flow will enter the wind hood 9 through the air inlet arranged on one side of the wind hood 9, which can promote the wind flow to enter the wind hood 9. When the wind flow passes through the impeller 8, it can drive the impeller 8 to rotate. Since the shape of the impeller 8 is arc-shaped, it will only rotate in one direction. When the impeller 8 rotates, it will drive the rotating rod 7 to rotate. When the rotating rod 7 rotates, it will drive the rotating generator 6 to operate, thus generating electric energy, and the electric energy generated by the rotating generator 6 will be transmitted to the energy storage box 5 through the transmission line for storage.

[0028] As an implementation mode, such as Figures 8 - 10 , the sealing structure is used to seal the surface of the photovoltaic panel 4. The sealing assembly includes a first sealing plate 24 and a second sealing plate 25. The first sealing plate 24 and the second sealing plate 25 are arranged up and down on one side of the photovoltaic panel 4. The sealing structure further includes a transmission gear 15, and the transmission gear 15 is rotatably connected to the inner wall of the installation box 3. Two groups of racks 16 distributed up and down are engaged on both sides of the transmission gear 15. A sliding groove 17 is opened on the inner wall of the rack 16. A sliding rod 18 is fixedly connected to the inner wall of the sliding groove 17. One end of the sliding rod 18 is fixedly connected with a convex tooth 20. A first spring 19 is fixedly connected to one side of the convex tooth 20. One end of the first spring 19 is fixedly connected to the inner wall of the sliding groove 17. A side plate 21 is fixedly connected to one side of the rack 16. A connecting plate 22 is fixedly connected to one side of the rack 16. A second spring 23 is fixedly connected to the bottom of the connecting plate 22. The second spring 23 is fixedly connected to the inner wall of the installation box 3. The two connecting plates 22 are respectively fixedly connected to one side of the first sealing plate 24 and the second sealing plate 25. Two guiding frames are fixedly connected to both sides of the installation box 3, and the two guiding frames are sleeved on both sides of the first sealing plate 24 and the second sealing plate 25.

[0029] Further, the drive structure can drive the drive gear 15 to rotate. When the drive gear 15 rotates, it will drive two racks 16 to move towards the center. When the racks 16 move, they will drive the connecting plate 22 arranged on one side to move. When the two connecting plates 22 move towards the center along with the two racks 16, they can drive the first sealing plate 24 and the second sealing plate 25 to move towards the center together, which is beneficial to closing the surface of the photovoltaic panel 4. When the end of the rack 16 moves to one side of the drive gear 15, the convex tooth 20 will be stuck on one side of the drive gear 15. When the drive gear 15 pushes the convex tooth 20 to move to one side, the convex tooth 20 will squeeze the first spring 19. When the convex tooth 20 fits against one side of the rack 16, the first spring 19 will push the convex tooth 20 to reset, and then the convex tooth 20 will be stuck into the next set of teeth of the drive gear 15, enabling the drive gear 15 to continue rotating and keeping the two racks 16 in the designated position. After the wind stops, the two connecting plates 22 and the racks 16 can be pushed to reset by the second spring 23. When the connecting plates 22 reset, they can also drive the first sealing plate 24 and the second sealing plate 25 to reset, thereby opening the surface of the photovoltaic panel 4 and enabling the photovoltaic panel 4 to receive light energy.

[0030] As Figure 7 , the drive structure is used to drive the first sealing plate 24 and the second sealing plate 25 to operate by using the kinetic energy on the wind structure. The drive structure includes a first bevel gear 10, which is fixedly connected to the outer wall of the rotating rod 7. A second bevel gear 11 is engaged with the bottom of the first bevel gear 10. A drive rod 12 is fixedly connected to one side of the second bevel gear 11. A third bevel gear 13 is fixedly connected to one end of the drive rod 12. A fourth bevel gear 14 is engaged with one side of the third bevel gear 13, and the fourth bevel gear 14 is fixedly connected to the bottom of the drive gear 15.

[0031] When the rotating rod 7 rotates, it will drive the first bevel gear 10 arranged on the outer wall to rotate. When the first bevel gear 10 rotates, it will drive the second bevel gear 11 engaged on one side to rotate. The second bevel gear 11 will drive the drive rod 12 and the third bevel gear 13 to rotate. When the third bevel gear 13 rotates, it will drive the fourth bevel gear 14 and the drive gear 15 to rotate, thereby driving the closing structure to operate through the drive gear 15.

[0032] As Figure 11 and Figure 12 , a first cleaning plate 28 is fixedly connected to the inner wall of the first sealing plate 24, a second cleaning plate 29 is fixedly connected to the inner wall of the second sealing plate 25. Cleaning pads are arranged at the bottoms of the first cleaning plate 28 and the second cleaning plate 29, and a plurality of leakage holes are formed on the surface of the second cleaning plate 29.

[0033] As an implementation manner, by respectively arranging a first cleaning plate 28 and a second cleaning plate 29 on the inner walls of the first sealing plate 24 and the second sealing plate 25, when the first sealing plate 24 and the second sealing plate 25 are closed and opened, the first cleaning plate 28 and the second cleaning plate 29 can be driven to slide on the surface of the photovoltaic panel 4, and the accumulated grit on the surface of the photovoltaic panel 4 can be swept away by the cleaning pads. Moreover, multiple groups of leakage holes arranged on the second cleaning plate 29 are conducive to the grit passing through the second cleaning plate 29 and falling downward when cleaning the grit.

[0034] As Figure 4 and Figure 5 , a collection hood 31 is fixedly connected to the bottom of the wind hood 9. The top end of the collection hood 31 is in a funnel shape. An expansion plate 32 is fixedly connected to the bottom of the collection hood 31. A sleeve is sleeved on the outer wall of the rotating rod 7. The first bevel gear 10 and the second bevel gear 11 are both arranged on the inner wall of the sleeve. A guiding cylinder 33 is fixedly connected to the top end of the sleeve. The guiding cylinder 33 is arranged inside the collection hood 31, and the guiding cylinder 33 is sleeved on the outer wall of the rotating rod 7.

[0035] As an implementation manner, by arranging a funnel-shaped collection hood 31 at the bottom of the wind hood 9, it is convenient for the grit in the wind hood 9 to fall downward into the collection hood 31, and through the cooperation of the guiding cylinder 33 and the collection hood 31, the grit is guided downward, and through the cooperation of the expansion plate 32 and the bottom of the guiding cylinder 33, the grit is poured downward in a circular shape, which is convenient for discharging the grit mixed in the wind hood 9.

[0036] As Figure 7 , a guiding strip 30 is fixedly connected to the bottom of the impeller 8. The shape of the guiding strip 30 is arc-shaped, and the bottom of the guiding strip 30 is inclined. The guiding strip 30 is arranged at the top end of the collection hood 31.

[0037] As an implementation manner, by arranging a guiding strip 30 at the bottom of the impeller 8, when the impeller 8 rotates, the guiding strip 30 can be driven to rotate together. When the guiding strip 30 rotates, due to the inclination on one side thereof, the surrounding grit can be gradually guided to the center until the grit at the bottom of the wind hood 9 is guided to the top end of the collection hood 31, which is convenient for cleaning the residual grit inside the wind hood 9.

[0038] As Figure 6 and Figure 13 , a collection box 34 is fixedly connected to one side of the bottom plate 1. A filter plate 35 is fixedly connected to one side of the collection box 34. The filter plate 35 is arranged obliquely and is arranged at the bottom of the second sealing plate 25. A transmission pipe 36 is fixedly connected to one side of the collection box 34. A frame plate 37 is fixedly connected to the outer wall of the energy storage box 5. The frame plate 37 is made of a heat-conducting material, and the transmission pipe 36 is fixedly connected to one side of the frame plate 37.

[0039] As an implementation method, by arranging a collection box 34 on one side of the bottom plate 1, when fog forms at night in desert areas, the water droplets condensed on the first sealing plate 24 and the second sealing plate 25 can slide downward by gravity, and the water droplets are guided by the first sealing plate 24, the second sealing plate 25 and two groups of guiding frames on both sides, so that the water droplets drip on the collection box 34, and the water in the collection box 34 is filtered by the filter plate 35 on the collection box 34 to prevent sand and gravel from entering the collection box 34, and the water in the collection box 34 will flow into the frame plate 37 through the transmission pipe 36 for storage, and when the energy storage box 5 needs to be cooled, the energy storage box 5 can be cooled by the water in the frame plate 37.

[0040] As Figure 6 and Figure 13 As shown in FIGS. and, a mounting plate 38 is fixedly connected to the top end of the collection box 34, a third spring 39 is fixedly connected to the inner wall of the mounting plate 38, a scraper 40 is fixedly connected to the bottom of the third spring 39, the scraper 40 is attached to the top end of the filter plate 35, a slope is arranged on one side of the scraper 40, the bottom of the second sealing plate 25 abuts against one side of the scraper 40, and small holes are formed in the bottom of the scraper 40.

[0041] When the second sealing plate 25 moves downward, it will abut against the slope on one side of the scraper 40 and move the scraper 40 upward to compress the third spring 39, and the small holes arranged on the scraper 40 are beneficial to allowing the condensed dew to pass through the small holes and enter the collection box 34 when the second sealing plate 25 is opened. When the second sealing plate 25 moves upward, the third spring 39 can be reset to push the scraper 40 to move downward, and the scraper 40 can scrape off the sand and gravel intercepted on the filter plate 35 during movement to prevent the sand and gravel from accumulating on the filter plate 35 all the time.

[0042] As Figure 11 As shown in FIGS., a closing plate 26 is fixedly connected to one side of the first sealing plate 24, and a cushion block 27 is fixedly connected to the inner wall of the closing plate 26.

[0043] As an implementation method, by arranging the closing plate 26 on the first sealing plate 24, when the first sealing plate 24 and the second sealing plate 25 are close to each other, it is convenient to fit the closing plate 26 and the cushion block 27 on the surface of the second sealing plate 25, thereby improving the sealing degree at the connection between the first sealing plate 24 and the second sealing plate 25 and preventing sand and gravel from entering through the gap between the first sealing plate 24 and the second sealing plate 25.

[0044] In this embodiment, to solve the problem of damage to the surface of the photovoltaic panel 4 in an environment with more wind and sand, when using the photovoltaic solar power generation device, the photovoltaic panel 4 can convert light energy into electrical energy and transmit the electrical energy to the energy storage box 5 for storage. Multiple modular photovoltaic panels 4 are installed in the installation box 3, which is beneficial to the installation and replacement of the photovoltaic panels 4.

[0045] In the event of strong wind weather, the air flow will enter the air hood 9 through the air inlet provided on one side of the air hood 9. When the air flow passes through the impeller 8, it can drive the impeller 8 to rotate. Since the shape of the impeller 8 is arc-shaped, it will only rotate in one direction. When the impeller 8 rotates, it will drive the rotating rod 7 to rotate. When the rotating rod 7 rotates, it will drive the rotary generator 6 to operate, thereby generating electrical energy, and the electrical energy generated by the rotary generator 6 will be transmitted to the energy storage box 5 through the transmission line for storage. When the rotating rod 7 rotates, it will drive the first bevel gear 10 to rotate. When the first bevel gear 10 rotates, it will drive the second bevel gear 11 to rotate. The second bevel gear 11 will drive the transmission rod 12 and the third bevel gear 13 to rotate. When the third bevel gear 13 rotates, it will drive the fourth bevel gear 14 and the transmission gear 15 to rotate. When the transmission gear 15 rotates, it will drive the two racks 16 to move towards the center. When the racks 16 move, they will drive the connecting plate 22 provided on one side to move. When the two connecting plates 22 move towards the center along with the two racks 16, they can drive the first sealing plate 24 and the second sealing plate 25 to move towards the center together, which is beneficial to closing the surface of the photovoltaic panel 4. When the first sealing plate 24 and the second sealing plate 25 are closed, they can be attached to the surface of the second sealing plate 25 through the closing plate 26 and the cushion block 27, thereby improving the sealing degree at the connection between the first sealing plate 24 and the second sealing plate 25 and preventing grit from entering through the gap between the first sealing plate 24 and the second sealing plate 25. When the first sealing plate 24 and the second sealing plate 25 move, they can also drive the first cleaning plate 28 and the second cleaning plate 29 to slide on the surface of the photovoltaic panel 4, and the grit accumulated on the surface of the photovoltaic panel 4 can be swept away through the cleaning pad. The multiple leakage holes provided on the second cleaning plate 29 are beneficial for the grit to fall downward through the second cleaning plate 29 when cleaning the grit. When the end of the rack 16 moves to the side of the transmission gear 15, the convex tooth 20 will be stuck on one side of the transmission gear 15. When the transmission gear 15 pushes the convex tooth 20 to move to one side, the convex tooth 20 will squeeze the first spring 19. When the convex tooth 20 fits on one side of the rack 16, the first spring 19 will push the convex tooth 20 to reset, and then the convex tooth 20 will be stuck into the next set of teeth of the transmission gear 15, enabling the transmission gear 15 to continue rotating and keeping the two racks 16 in the specified position. After the wind stops, the impeller 8 and the rotating rod 7 lose kinetic energy, and the two connecting plates 22 and the racks 16 can be pushed to reset by the second spring 23. When the connecting plates 22 reset, they can also drive the first sealing plate 24 and the second sealing plate 25 to reset, thereby opening the surface of the photovoltaic panel 4 and enabling the photovoltaic panel 4 to receive light energy.

[0046] As an implementation manner, by providing a funnel-shaped collecting cover 31 at the bottom of the wind cover 9, it is convenient for the grit in the wind cover 9 to fall downward into the collecting cover 31, and through the cooperation of the guiding cylinder 33 and the collecting cover 31, the grit is guided downward, and through the cooperation of the expansion plate 32 and the bottom of the guiding cylinder 33, the grit is poured downward in a ring shape, which is convenient for discharging the grit mixed in the wind cover 9. When the impeller 8 rotates, the guiding strip 30 is driven to rotate together. When the guiding strip 30 rotates, since one side of it is inclined, the surrounding grit can be gradually guided to the center until the grit at the bottom of the wind cover 9 is guided to the top of the collecting cover 31, which is convenient for cleaning the residual grit inside the wind cover 9.

[0047] When fog forms at night in desert areas, the water droplets condensed on the first sealing plate 24 and the second sealing plate 25 will slide downward by gravity, making the water droplets drip onto the collecting box 34, and the water is filtered by the filter plate 35 on the collecting box 34 to prevent grit from entering the collecting box 34. The water in the collecting box 34 will flow into the frame plate 37 through the transmission pipe 36 for storage. When the energy storage box 5 needs to be cooled, the water in the frame plate 37 can be used to cool the energy storage box 5. When the second sealing plate 25 moves downward, it will abut against the slope on one side of the scraper 40 and move the scraper 40 upward to compress the third spring 39. The small holes provided on the scraper 40 can enable the condensed dew to pass through the small holes and enter the collecting box 34. When the second sealing plate 25 moves upward, the third spring 39 can be reset to push the scraper 40 to move downward, and when the scraper 40 moves, it can scrape off the grit intercepted on the filter plate 35 to prevent the grit from accumulating on the filter plate 35 all the time and causing blockage.
