Description

Technical Field

[0002] Photovoltaic energy storage is a power generation system consisting of photovoltaic equipment and energy storage equipment, designed to improve the quality of electric energy. This system uses solar photovoltaic power generation and directly converts solar radiation energy into electricity through the photovoltaic effect of semiconductor materials. It can operate in two modes: independent operation and grid-connected operation. The application of photovoltaic energy storage systems includes but is not limited to remote mountainous areas, areas without electricity, islands, communication base stations, and street lights. Among them, photovoltaic off-grid power generation systems do not rely on the power grid and operate independently, making them suitable for areas without a power grid or where power outages are frequent.

[0004] With the increasing development of photovoltaic new energy, photovoltaic energy storage integrated machines are being built in sunny areas.

Lifting components 5 for use with the sub-frame 2 are provided on all sides of the bottom of the main frame 1 to effectively protect the photovoltaic panels in extremely harsh weather.

[0049] like Figures 5 to 12 The first and second latches 33 are connected to each other to form a plurality of latches 35, each of which is connected to the latch assembly 31. The first and second latches 33 are connected to each other to form a plurality of latches 35. The first and second latches 33 are connected to each other to form a plurality of latches 35.

[0050] A sunlight tracking sensor 8 is embedded in the center of the top of the main solar panel 38, which is convenient for the main solar panel 38 and the two sets of auxiliary solar panels 37 expanded to capture sunlight and perform tracking angle rotation, thereby extending the light reception time of the main solar panel 38 and the two sets of auxiliary solar panels 37, and the cross-sectional area of ​​the auxiliary solar panels 37 is half of the cross-sectional area of ​​the main solar panel 38. Hidden cavities that slide with the auxiliary solar panels 37 are provided on both sides of the bottom of the main solar panel 38, and the cross-sectional area of ​​the auxiliary solar panels 37 is the same as the cross-sectional area of ​​the hidden cavity, which is conducive to the storage and hiding of the two sets of auxiliary solar panels 37. Slide rails 9 are provided on both sides of the main solar panel 38 near the hidden cavity, and the inner cavity of the slide rail 9 is slidably connected to a slide bar 10 that is fixedly matched with the auxiliary solar panel 37, which plays a sliding limit role for the two sets of auxiliary solar panels 37 during the expansion and storage process, thereby facilitating the smooth expansion and storage of the two sets of auxiliary solar panels 37.

[0051] The adjusting assembly 4 includes a driving bevel gear 41 fixed on the output shaft of the double-headed motor 31 near the first electric push rod 32, a driven bevel gear 42 is provided on one side of the driving bevel gear 41, and the outer side of the driven bevel gear 42 is fixedly connected to a second electric push rod 43 that rotates with the main frame 1, the second electric push rod 43 is first used to adjust the meshing stroke between the driven bevel gear 42 and the driving bevel gear 41, the other side of the second electric push rod 43 is fixedly connected to a driving circular gear 44, and the bottom of the driving circular gear 44 is meshed with a semicircular gear ring 45, and then through the meshing transmission cooperation between the driving bevel gear 41 and the driven bevel gear 42, the meshing transmission cooperation between the driving circular gear 44 and the semicircular gear ring 45 is engaged;

[0052] Both sides of the top of the main frame 1 are fixedly connected with a slide 48, and the top of the slide 48 is slidably connected with a slide 46, wherein the inner side of one group of slides 46 is fixedly connected to the semicircular gear ring 45, and both sides of the slide 46 are fixedly connected with a connecting plate 47, and the semicircular gear ring 45 drives the slide 46 composed of two groups of connecting plates 47 to adjust the angle accordingly in the slide 48. With the cooperation of the sunlight tracking sensor 8 to capture and track the sunlight, the photovoltaic panels can follow the natural law of "rising in the east and setting in the west" to adjust the angle in real time, and realize the real-time azimuth adjustment effect of the photovoltaic panels according to the natural rising and setting law of the sun, thereby extending the light receiving time of the main solar panel 38 and the two groups of auxiliary solar panels 37, and further improving the solar energy conversion power generation and photovoltaic energy storage rate.

[0053] The lifting assembly 5 includes a third electric push rod 51 embedded in the other output shaft of the double-headed motor 31, and the piston rod of the third electric push rod 51 is fixedly connected to the main bevel gear 52. The four sides below the main bevel gear 52 are provided with a bevel gear frame 53 that rotates with the main frame 1. In extremely bad weather conditions such as heavy rain and hail, the meshing stroke between the main bevel gear 52 and the four-group bevel gear frame 53 is first adjusted by the third electric push rod 51, and the other end of the bevel gear frame 53 is meshed with a sub-bevel gear 54 that rotates with the sub-frame 2, and then the main bevel gear 52, the four-group bevel gear frame 53 and the four-group sub-bevel gear 54 are synchronously meshed and driven. , the inner cavity of the secondary bevel gear 54 is fixedly connected with a threaded long rod 55, and the outer side of the threaded long rod 55 is threadedly connected with a threaded long cylinder 56 that slides with the secondary frame 2, and both sides of the threaded long cylinder 56 are fixedly connected with an anti-blocking frame 57, and the inner cavity of the anti-blocking frame 57 is fixedly connected with a transparent plate 58. The four groups of threaded long rods 55 drive the anti-blocking frames 57 and the transparent plates 58 on the four groups of threaded long cylinders 56 to rise and shield the photovoltaic panels to prevent extreme weather conditions such as heavy rain and hail from damaging the main solar panels 38 and the two groups of auxiliary solar panels 37, thereby extending the service life of the main solar panels 38 and the two groups of auxiliary solar panels 37;

[0054] Vertical grooves 11 are provided on both sides of the inner cavity of the sub-frame 2 for sliding cooperation with the anti-blocking frame 57, and the transparent plate 58 is made of acrylic material, which serves as a sliding limit for the anti-blocking frame 57, which is beneficial to the smooth lifting and lowering of the anti-blocking frame 57. At the same time, the use of acrylic material can improve the strength of the transparent plate 58 while ensuring the transparency of the transparent plate 58, which is beneficial for patrol personnel to observe the main solar panel 38 inside through the transparent plate 58.

[0055] like Figures 13 to 16 As shown, since most photovoltaic energy storage equipment is built in open outdoor areas, the photovoltaic panels cannot be effectively shielded and protected in extremely severe weather such as thunderstorms and hail, which directly causes the photovoltaic panels to malfunction and be damaged, shortening the service life of the photovoltaic panels. The tops of both sides of the anti-blocking frame 57 are fixedly connected with a clockwork box 6, and a telescopic component 7 that is uniformly lifted and lowered with the lifting component 5 is provided between the clockwork boxes 6. The telescopic component 7 includes a rotating rod 71 that rotates in the inner cavity of the clockwork box 6, and both ends of the rotating rod 71 are provided with a clockwork 72 that is used in conjunction with the clockwork box 6. An anti-blocking cloth 73 is provided on the rotating rod 71, and the head end of the anti-blocking cloth 73 is fixedly connected to a frame 74. The outer side of the center of the frame 74 is fixedly connected to an electric telescopic rod 75 that is fixedly matched with the anti-blocking frame 57, and a first positioning magnet 76 and a second positioning magnet 76 are provided on opposite sides of the frame 74. The first positioning magnet 77 and the second positioning magnet 76 and the second positioning magnet 77 have opposite magnetic poles. When extremely bad weather such as thunderstorms and hail occurs, the four groups of raised anti-blocking frames 57 and transparent plates 58 first shield the side spaces of the auxiliary solar panel 37 and the main solar panel 38. Then, the two groups of electric telescopic rods 75 that rise synchronously with the four groups of anti-blocking frames 57 drive the anti-blocking cloth 73 wrapped around the two groups of rotating rods 71 ​​to be pulled inward synchronously through the two groups of skeletons 74, and pull the springs 72 at both ends of the rotating rods 71 ​​accordingly. Then, the two groups of anti-blocking cloth 73 that are pulled into place and closed shield the top space of the auxiliary solar panel 37 and the main solar panel 38 to prevent thunderstorms and hail from causing damage to the auxiliary solar panel 37 and the main solar panel 38, thereby extending the service life of the auxiliary solar panel 37 and the main solar panel 38.

[0056] Specifically, the working principle of this photovoltaic energy storage integrated machine is as follows: when expanding the photovoltaic panels, the first electric push rod 32 is first controlled to open and drive the locking head 33 to move up and clamp into the locking groove 35 at the bottom of the swing arm 34, and then the double-headed motor 31 is controlled to open and the locking head 33 that is clamped in place drives the swing arm 34 to rotate forward, and the swing arm 34 drives the two sets of connecting rods 36 to extend outward. The two sets of slide rails 9 and slide bars 10 play a sliding limit role on the two sets of auxiliary solar panels 37. The two sets of connecting rods 36 drive the two sets of auxiliary solar panels 37 to expand synchronously outward within the two sets of hidden cavities at the bottom of the main solar panel 38. After the two sets of auxiliary solar panels 37 are expanded into place, the double-headed motor 31 is first controlled to pause, and then the first electric push rod 32 is controlled to close and drive the locking head 33 to move downward and disengage from the locking groove 35 at the bottom of the swing arm 34 to the initial position. The expansion of the two sets of auxiliary solar panels 37 on the main solar panel 38 is completed, thereby increasing the light-receiving area of ​​the photovoltaic panel.

[0057] When adjusting the light tracking of the photovoltaic panel, first control the second electric push rod 43 to open and drive the driven bevel gear 42 to move forward and get into the meshing part of the driving bevel gear 41, then control the double-headed motor 31 to open again and drive the driven bevel gear 42 to rotate forward or reverse through the driving bevel gear 41 that is meshed in place. At this time, the locking head 33 on the first electric push rod 32 is in an idling state, and the driven bevel gear 42 drives the driving circular gear 44 to rotate forward or reverse through the second electric push rod 43, and the driving circular gear 44 drives the semicircular gear ring 45 to rotate forward or reverse. 45 drives the two sets of slides 46 connected by two sets of connecting plates 47 to rotate in the two sets of slide seats 48 in a forward or reverse angle. At the same time, the sunlight tracking sensor 8 captures and tracks the angle of sunlight in real time, so that the main solar panel 38 and the two sets of extended auxiliary solar panels 37 follow the natural law of the sun "rising in the east and setting in the west" and adjust their angles in real time. This forces the main solar panel 38 and the two sets of extended auxiliary solar panels 37 to always receive sunlight. The main solar panel 38 and the two sets of extended auxiliary solar panels 37 then convert solar energy into electrical energy and store it in the two sets of storage batteries 12.

[0058] In extremely bad weather such as thunderstorms and hail, the main solar panel 38 and the two sets of extended auxiliary solar panels 37 are first controlled to convert their angles to the initial horizontal state, and then the two sets of extended auxiliary solar panels 37 are controlled to reset and hide in the two hidden cavities at the bottom of the main solar panel 38. After the main solar panel 38 returns to the initial horizontal state, the double-headed motor 31 is first controlled to pause, and then the third electric push rod 51 is controlled to start and drive the main bevel gear 52 to move down and get stuck in the meshing part of the four sets of bevel gear racks 53. Then, the double-headed motor 31 is controlled to start again and the four sets of bevel gear racks 53 are driven to rotate synchronously through the main bevel gear 52 that is meshed in place. At this time, the locking head on the first electric push rod 32 33 and the driving bevel gear 41 are in an idling state, and the other end gear of the four-group bevel gear frame 53 drives the four-group auxiliary bevel gear 54 to rotate synchronously therewith, and the four-group auxiliary bevel gear 54 drives the four-group threaded long rod 55 to rotate synchronously therewith, and the four-group threaded long rod 55 drives the anti-blocking frame 57 on the four-group threaded long cylinder 56 to rise in the vertical slot 11 on both sides of the four-group auxiliary frame 2. After the four-group anti-blocking frame 57 and the transparent plate 58 are raised into place, the space around the main solar panel 38 after it has returned to its initial horizontal state is blocked. First, the third electric push rod 51 is controlled to close and drive the main bevel gear 52 to move up and disengage from the meshing part of the four-group bevel gear frame 53 to the initial position, and then the double-headed motor 31 is controlled to close;

[0059] At the same time, the four groups of anti-blocking frames 57 drive the two groups of rotating rods 71 ​​and the electric telescopic rods 75 to rise synchronously to the predetermined position through the two groups of spring barrels 6, and then control the two groups of electric telescopic rods 75 to drive the two groups of anti-blocking cloths 73 to be pulled inward synchronously through the two groups of skeletons 74. While the two groups of anti-blocking cloths 73 are pulled inward, they also drive the two groups of rotating rods 71 ​​to synchronously pull the springs 72 in the two groups of spring barrels 6 until the first positioning magnets 76 and the second positioning magnets 77 on the two groups of skeletons 74 are adsorbed in place. After the two groups of anti-blocking cloths 73 are closed, they return to their initial horizontal state. After blocking the top space of the main solar panel 38, the two sets of electric telescopic rods 75 are controlled to close.
