It aims to solve the instability problem caused by the reliance on weather for new energy sources through multi-link linkage, and provide core support for the green energy transition. The integrated power generation, grid, load, and energy storage model is a key path to building a new power system with new energy sources as the main body, and it is of great significance for promoting energy transition and economic and social development.

[0003] Referring to the patent application with publication number CN221767883U, an outdoor portable photovoltaic power generation and energy storage device is disclosed. It can detect the position of the light source by setting a PSD detector, set a rotating component to facilitate rotating the energy storage box, set a cover opening component to facilitate adjusting the angle of the cover so that the solar panels on the cover of the energy storage box can receive sunlight to the maximum extent, and set a handle and a moving wheel for easy movement.

[0004] A comprehensive analysis of the above-mentioned patents reveals the following shortcomings: Existing integrated photovoltaic power generation and energy storage devices and methods suffer from several drawbacks. The energy storage batteries are susceptible to temperature anomalies during charging and discharging, leading to decreased energy storage efficiency. Furthermore, the ventilation area is difficult to dynamically adjust based on the heat generated by the batteries, resulting in relatively fixed heat dissipation intensity. This makes the batteries prone to high-temperature aging or low-temperature inefficiency, shortening their lifespan. Additionally, the batteries are often stacked, causing heat accumulation and making it difficult to implement targeted heat dissipation control for each individual battery. Therefore, it is necessary to provide an integrated photovoltaic power generation and energy storage device and method to address these technical problems. Summary of the Invention

[0016] Beneficial effects This invention provides an integrated photovoltaic power generation and energy storage device and method. Compared with the prior art, it has the following advantages: 1. A photovoltaic power generation and energy storage device and method integrating source, grid, load and storage, wherein through the cooperation between the power generation and energy storage box, the support box mechanism and the energy storage battery body, the support box mechanism used to install the energy storage battery body can achieve adaptive operation of heat dissipation, dehumidification and drying, ensuring that the energy storage battery body can maintain optimal performance under all charging and discharging conditions, avoiding the decline in energy storage efficiency due to abnormal temperature and humidity, ensuring the reliability of energy storage and release, and realizing adaptive control of operating conditions, not only reducing the manufacturing cost and failure probability of the energy storage device, but also quickly responding to load changes in the source, grid, load and storage system, and adapting to the complex operating conditions of outdoor photovoltaic power generation.

[0017] 2. A photovoltaic power generation and energy storage device and method integrating source, grid, load and storage, through the coordinated operation of a dynamic adjustment component, a connecting frame component and a dehumidification component, the annular heat-conducting wire in the dynamic adjustment component can sense the temperature inside the support box in real time, and transfer the heat to the mercury in the storage box.

A piston 352 is slidably arranged between the inner cavity side walls of the liquid storage box 351. A support rod 353 is fixedly arranged in the middle of the bottom of the piston 352.

[0027] Through the coordinated operation of the dynamic adjustment component 35, the connecting frame component 36, and the air blowing and dehumidification component 33, the annular heat-conducting wire 356 in the dynamic adjustment component 35 can sense the temperature inside the support box body 31 in real time, transferring heat to the mercury in the liquid storage box 351. Utilizing the thermal expansion and contraction characteristics of mercury, the piston 352 and the support rod 353 are driven to rise and fall. The teeth 354 on the support rod 353 mesh with the toothed ring 362, driving the cam 363 to rotate, thereby pushing the L-shaped adjustment plate 339 and the U-shaped adjustment clamp 336 to move. This allows for dynamic adjustment of the ventilation area of ​​the air intake filter plate 32. When the energy storage battery body 4 is under high load discharge and the heat generation increases... When the heat generation is high, the ventilation area is automatically adjusted and expanded, the fan 332 introduces more cold air, and the heat dissipation intensity is increased simultaneously. When the heat generation decreases, the extension spring 3312 drives the component to reset, the ventilation area shrinks, and the heat dissipation intensity is adaptively reduced.

Waste heat is used to dynamically dry and reuse the honeycomb molecular sieve plate 334. During the heat dissipation process, some hot air is blown onto the honeycomb molecular sieve plate 334 inside the U-shaped adjusting clamp 336 through the gas gathering hood 38, the air guiding branch pipe 37, and the first telescopic branch pipe 337.

At the same time, the movement of the U-shaped adjusting clamp 336 can adapt to different air intake volumes and adjust the dehumidification contact area, realizing a closed-loop synergy of heat dissipation, dehumidification, and drying, which greatly improves energy storage. The device's operational stability in complex environments is ensured through the cooperation between the support box body 31, the lower T-shaped bracket 39, the upper T-shaped bracket 310, and the baffle. Several support box bodies 31 are evenly arranged from top to bottom within the power generation and energy storage box 1. Each support box body 31 forms an independent bearing space through the lower T-shaped bracket 39, the upper T-shaped bracket 310, and the baffle, allowing the energy storage battery body 4 to be placed in separate areas. This avoids heat accumulation caused by battery stacking and ensures that the heat within each support box body 31 can form an independent flow path. Targeted heat dissipation control can be performed based on the actual heat generation of each energy storage battery body 4.

[0028] This invention also provides an energy storage method for an integrated photovoltaic power generation and energy storage device, which utilizes the integrated photovoltaic power generation and energy storage device. The specific method includes the following steps: Step 1: First, the energy storage device is deployed in the integrated photovoltaic power generation scenario of source-grid-load-storage. During the power generation process of the external photovoltaic modules, if excess power is generated, it is stored by several energy storage battery bodies 4 to form an energy reserve. When the external photovoltaic modules generate insufficient power or the grid is at its peak load, the energy storage battery body 4 immediately starts the discharge and replenishment mode to supply power to the external grid or load. During this process, the energy storage battery body 4 will continuously generate heat due to the conversion of electrical energy. The heat accumulates inside the support box body 31, triggering the heat dissipation and dehumidification functions of the support box mechanism 3 to be carried out simultaneously. At this time, the blowing and dehumidification components 33 and the dynamic adjustment components 35 on both sides of the support box body 31 enter the standby state. The annular heat conduction wire 356 senses the temperature change inside the support box body 31 in real time and transfers the heat to the mercury in the liquid storage box 351. Step 2: The dynamic adjustment component 35, based on the changes in heat generation of the energy storage battery body 4, and in conjunction with the connecting frame component 36 and the air blowing and dehumidification component 33, adjusts the heat dissipation intensity of the energy storage battery body 4 in real time to stabilize the internal temperature of the support box body 31. When the heat generation of the energy storage battery body 4 increases, such as during high-load discharge or high-temperature operation, the internal temperature of the support box body 31 rises. The annular heat-conducting wire 356 conducts the heat to the heat-conducting ring 357, thereby lowering the temperature of the mercury inside the liquid storage box 351. As the temperature rises, the mercury expands due to heat, pushing the piston 352 upward. The piston 352 then drives the support rod 353 to move vertically upward. The teeth 354 at the lower part of the support rod 353 mesh with the gear ring 362 of the connecting frame assembly 36, driving the gear ring 362 and the crossbar 361 to rotate synchronously. The cam 363 on the left side of the crossbar 361 rotates along with it. The cam 363 pushes the lower edge plate 3310 of the air blowing and dehumidifying assembly 33, causing the lower edge plate 3310 to drive the L-shaped adjusting plate 339 to slide along the support frame 331, pressing... The telescopic spring 3312 between the shrinking protrusion 3311 and the L-shaped adjusting plate 339, and the L-shaped adjusting plate 339 drive the U-shaped adjusting clamp 336 to move synchronously, increasing the ventilation area of ​​the air intake filter plate 32. At the same time, the fan 332 starts, allowing more external air to enter the support box body 31, thereby increasing the heat dissipation intensity. When the heat generated by the energy storage battery body 4 decreases, such as during low-load discharge or when the ambient temperature decreases, the temperature inside the support box body 31 drops, and the mercury in the liquid storage box 351 contracts, causing the piston to... 352 and support rod 353 move downwards under the action of gravity, tooth 354 drives toothed ring 362 to rotate in the opposite direction, the thrust of cam 363 on lower edge plate 3310 gradually disappears, under the elastic action of telescopic spring 3312, it will push L-shaped adjustment plate 339 and U-shaped adjustment clamp 336 to move closer to the initial position, reduce the ventilation area of ​​air intake filter plate 32, and reduce the heat dissipation intensity at the same time, so that the internal temperature of support box body 31 is maintained in the optimal operating temperature range of energy storage battery body 4; Step 3: While the fan 332 draws in external air to cool the energy storage battery body 4, the dehumidification component 33 simultaneously completes the dehumidification process, ensuring that the air entering the support box body 31 is dry and preventing the energy storage battery body 4 from being damaged by moisture. The external air is first filtered by the air intake filter plate 32 on the left side of the support box body 31 to intercept impurities and other particles, and then enters the interior of the support frame 331. It is then dehumidified by the honeycomb molecular sieve plate 334 on the bearing plate 333. The honeycomb molecular sieve plate 334 is used to adsorb moisture in the air to achieve air intake drying. The dried air is then blown into the support box body 31 by the driving force of the fan 332, that is, blown onto the surface of the energy storage battery body 4, quickly removing the heat generated by the energy storage battery body 4. The hot air is finally discharged to the outside of the power generation and energy storage box 1 through the heat dissipation window 34. During the process, as the U-shaped adjusting clamp 336 moves, the adjustable 33 The contact area between the honeycomb molecular sieve plate 334 and the drawn-in air is adapted to the dehumidification requirements of different air intake volumes. Another part of the honeycomb molecular sieve plate 334 that does not participate in dehumidification can be automatically dried in time. During the heat dissipation process, the hot air in the support box body 31 is discharged through the heat dissipation window 34. At the same time, some hot air enters the air guide branch pipe 37 through the air gathering cover 38, and then enters the first telescopic branch pipe 337. Finally, it blows towards the honeycomb molecular sieve plate 334 in the U-shaped adjusting clamp 336, and discharges the water vapor in the honeycomb molecular sieve plate 334 in the U-shaped adjusting clamp 336 through the second telescopic branch pipe 338 and the exhaust branch pipe 335, realizing the drying operation of the honeycomb molecular sieve plate 334. This ensures that the dehumidification effect remains stable when participating in dehumidification later, realizing the coordinated operation of heat dissipation and dehumidification, and ensuring the long-term reliable operation of the energy storage battery body 4.
