Description

Technical Field

[0001] The present invention relates to the technical field of energy storage equipment, and in particular to a stacked photovoltaic energy storage system based on a zero-carbon base station. Background Art

[0002] The stacked solar energy storage system based on zero-carbon base stations is an innovative energy solution that combines solar photovoltaic panels with high-efficiency energy storage technology. The system can collect solar energy through photovoltaic panels when the sun is sufficient and convert it into electricity for base stations. At the same time, excess electricity is stored in the energy storage device. At night or in bad weather, the energy storage device releases electricity to ensure continuous power supply to the base station. The stacked solar energy storage system not only achieves zero carbon emissions for the base station, but also significantly reduces operating costs and improves energy utilization efficiency.

[0003] The patent with publication number CN220527725U discloses a split energy storage mobile power supply device, including a base, the inner wall of the base is slidably connected to a bottom plate, the upper surface of the bottom plate is fixedly connected to a split energy storage box, and support structures are provided on both sides of the base, the support structure includes two sleeves and a hook, and the inner walls of the two sleeves are slidably connected to a movable plate. The movable plate can be squeezed by a first fastening bolt to fix the extended length of the movable plate, and the connection of the first hinged plate and the rotating plate is combined to form a stable triangular support structure, which can improve the supporting performance of the split energy storage mobile power supply device.

[0004] In existing energy storage devices, batteries are often connected in series or in parallel to form battery packs and charged as a whole. However, due to factors such as manufacturing process, use environment and battery aging, there are performance differences between batteries, such as inconsistent parameters such as capacity, internal resistance and open circuit voltage. When the battery pack voltage reaches the charging cutoff point, some batteries may be fully charged while others are not fully charged. Continuing to charge will cause the battery to be overcharged, which will accelerate battery aging and shorten the battery life. That is, the traditional connection method for charging the battery pack as a whole is not conducive to regulating the charging status of each battery. In addition, a large amount of heat will be generated when the battery is charged, and the heat dissipation design of existing energy storage devices is mostly static. For example, the size and position of the ventilation holes are fixed, and it is impossible to dynamically adjust according to the actual charging status and heat dissipation requirements of the battery. In view of this, we propose a stacked solar energy storage system based on a zero-carbon base station. Summary of the invention

[0051] Specifically, the placement group 310 includes a movable horizontal plate 311, a plate frame 312 arranged on the top surfaces of the front and rear ends of the movable horizontal plate 311, an outer convex frame 314 arranged on the outer side wall of the plate frame 312, and two limiting brackets 315 arranged on the top surface of the movable horizontal plate 311.

[0052] Furthermore, the movable horizontal plate 311 is slidably connected to the inside of the fixed top frame 130, and a plurality of panel plug holes 3110 that pass through the top and bottom are opened on the top surface of the movable horizontal plate 311. The longitudinal cross-section of the panel frame 312 is in an inverted concave shape and is clamped and fixed on the top surface of the movable horizontal plate 311.

[0055] In this embodiment, Figure 7-Figure 8 As shown, the driving group 320 includes a dual-axis motor 321, a driving shaft 322 arranged on the output shafts at both ends of the dual-axis motor 321, a driving gear 323 that rotates as the driving shaft 322 rotates, a shaft end arc gear 324 arranged at the end of the driving shaft 322, and a docking gear 325 that rotates as the shaft end arc gear 324 rotates;

[0056] Specifically, the dual-axis motor 321 is fixedly connected to the top surface of the movable horizontal plate 311 by bolts, the driving shaft 322 is coaxially connected to the output shaft of the dual-axis motor 321, the end of the driving shaft 322 extends to the interior of the plate frame 312, and the driving gear 323 is fixedly connected to the outer wall of the driving shaft 322 by a bayonet pin. The driving gear 323 is meshed with the fixed gear plate 140 and there is a small arc area on the outer ring wall.

[0057] Furthermore, the shaft end arc gear 324 is fixedly connected to the end position of the driving shaft 322 by a bayonet pin, and the docking gear 325 is rotatably connected to the inner side walls of the front and rear ends of the panel frame 312 through the center rod of the wheel body, and the docking gear 325 meshes with the gear teeth on the shaft end arc gear 324.

[0058] Furthermore, the dual-axis motor 321 in the driving group 320 is started to drive the driving shaft 322 to rotate, and then drive the driving gear 323 to rotate. After the driving gear 323 conflicts with the fixed gear plate 140, the placement group 310 is driven to move as a whole inside the fixed top frame 130. Subsequently, when the placement group 310 moves as a whole to the top of the next energy storage battery 200, a small arc-shaped area of ​​the outer ring wall of the driving gear 323 moves to the position of the fixed gear plate 140, so that the position of the placement group 310 no longer changes. Then, the continuously rotating shaft end arc gear 324 will conflict with the docking gear 325, driving the docking gear 325 to rotate half a circle.

[0059] In this embodiment, Figure 9-10As shown, the transmission group 330 includes a dial 331, four levers 332 regularly arranged on the outer wall of the dial 331, a groove wheel 333 that rotates as the dial 331 rotates, a transmission shaft 334 arranged inside the groove wheel 333, and a shaft end rotating disk 335 that rotates as the transmission shaft 334 rotates;

[0060] Specifically, the dial 331 is fixedly connected to the outer wall of the center rod of the wheel body of the docking gear 325 by a bayonet pin, the lever 332 and the dial 331 are integrally formed, the transmission shaft 334 is rotatably connected to the inside of the plate frame 312, the groove wheel 333 is fixedly connected to the outer wall of the transmission shaft 334 by a bayonet pin, the shaft end turntable 335 is clamped and fixed at the inner end position of the transmission shaft 334, and a disk body protrusion 3350 is integrally formed on the outer wall of the shaft end turntable 335.

[0061] Furthermore, the connection group 340 includes a fixing plate 341 , a plurality of charging plugs 342 disposed at the bottom of the fixing plate 341 , and an external wire 343 for connecting to the photovoltaic system.

[0062] Furthermore, the fixing plate 341 is slidably connected to the inside of the two limit brackets 315 , and the front and rear ends of the fixing plate 341 are provided with plate end slide grooves 3410 for providing a moving range for the disc body protrusion 3350 , and the charging plug 342 and the external cable 343 are both clamped and fixed to the fixing plate 341 .

[0063] Furthermore, after the docking gear 325 rotates half a circle, it drives the dial 331 in the transmission group 330 to rotate half a circle, and then drives the groove wheel 333 to rotate half a circle through the lever 332, thereby driving the transmission shaft 334 and the shaft end turntable 335 to rotate half a circle. At this time, the dual-axis motor 321 is turned off. After the shaft end turntable 335 rotates half a circle, the change in the position of the disc body protrusion 3350 during the rotation process will drive the position of the fixed plate 341 to change, and the fixed plate 341 together with the charging plug 342 will move downward, and then the charging plug 342 will be inserted into the socket at the top of the energy storage battery 200.

[0064] In this embodiment, Fig.12 As shown, the ventilation mechanism 400 includes a disassembly cover 410, two upper and lower parallel sliding bars 420, two connecting rods 430 connected between the two sliding bars 420, a plurality of windshield plates 440 clamped and fixed between the two connecting rods 430, an extension rod 450 clamped and fixed on the top surface of the upper sliding bar 420, and a plurality of lifting springs 460 welded and fixed on the bottom surface of the lower sliding bar 420;

[0065] Specifically, the upper and lower ends of the disassembly cover 410 are clamped and fixed to the bottom surface of the fixed top frame 130 and the top surface of the fixed bottom plate 110, and a number of regularly distributed ventilation grooves that penetrate inside and outside are opened on the outer wall of the disassembly cover 410. The filter net 470 is clamped and fixed to the inner groove wall of the ventilation groove of the disassembly cover 410.

[0066] Furthermore, the sliding bar 420 is slidably connected to the inner wall of the disassembly cover 410, and the upper and lower ends of the connecting rod 430 are respectively clamped and fixed on the outer walls of the upper and lower sliding bars 420, the number of wind shields 440 and the filter screens 470 are the same and their positions correspond one to one, the end of the extension rod 450 extends to the interior of the fixed top frame 130, and the bottom end of the lifting spring 460 is welded and fixed to the bottom horizontal plate of the disassembly cover 410.

[0067] Furthermore, when the charging device 300 moves to the top of the next energy storage battery 200, the inner convex bracket 313 on the outer side wall of the movable horizontal plate 311 will squeeze the extension rod 450 in the ventilation mechanism 400, thereby driving the extension rod 450 to move downward, and then allowing the plurality of wind shields 440 to move downward together, thereby increasing the wind flow area of ​​the ventilation slot on the disassembly cover 410, thereby increasing the air circulation and helping the battery to dissipate heat quickly. After the charging device 300 leaves, the lifting spring 460 will use its own elastic force to drive the two sliding bars 420, the two connecting rods 430 and the plurality of wind shields 440 to return to their initial positions.

[0068] Finally, it should be noted that the dual-axis motor 321 involved in the present invention is a universal standard part or a part known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, the dual-axis motor 321 is connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the field.

[0069] When the stacked photovoltaic energy storage system based on the zero-carbon base station of the present invention is used, first, the connection group 340 in the charging device 300 fully charges one of the energy storage batteries 200 stored in the battery storage compartment 100;

[0070] The dual-axis motor 321 in the driving group 320 is started to drive the driving shaft 322 to rotate, thereby driving the driving gear 323 to rotate. After the driving gear 323 contacts the fixed gear plate 140, the placement group 310 is driven to move inside the fixed top frame 130.

[0071] Then, when the placement group 310 moves as a whole to the top of the next energy storage battery 200, a small arc-shaped area of ​​the outer ring wall of the driving gear 323 moves to the position of the fixed tooth plate 140, so that the position of the placement group 310 does not change;

[0072] Then, the continuously rotating shaft end arc gear 324 will conflict with the docking gear 325, driving the docking gear 325 to rotate half a circle, and driving the dial 331 in the transmission group 330 to rotate half a circle, and then driving the groove wheel 333 to rotate half a circle through the lever 332, thereby driving the transmission shaft 334 and the shaft end rotating disk 335 to rotate half a circle. At this time, the dual-axis motor 321 is turned off;

[0073] After the shaft end rotating disk 335 rotates half a circle, the position change of the disk body protruding rod 3350 during the rotation process will drive the position of the fixing plate 341 to change, so that the fixing plate 341 and the charging plug 342 move downward, and then the charging plug 342 is inserted into the socket on the top of the energy storage battery 200;

[0074] When the charging device 300 moves to the top of the next energy storage battery 200, the inner convex bracket 313 on the outer side wall of the movable horizontal plate 311 will squeeze the extension rod 450 in the ventilation mechanism 400, thereby driving the extension rod 450 to move downward, and then the plurality of wind shields 440 move downward together, thereby increasing the wind passing area of ​​the ventilation slot on the disassembly cover 410, thereby increasing the air circulation and helping the battery to quickly dissipate heat;

[0075] When the next energy storage battery 200 is fully charged, the dual-axis motor 321 is started again, and the shaft end turntable 335 in the connection group 340 rotates half a circle again, so that the connection group 340 moves up as a whole. Subsequently, the driving group 320 will continue to drive the charging device 300 to move toward the remaining energy storage batteries 200.
