[0002] Photovoltaic power generation and energy storage battery modules combine photovoltaic power generation systems with energy storage batteries, primarily used to achieve efficient storage and flexible application of solar energy. Energy storage battery modules typically consist of lithium iron phosphate batteries or lithium-ion batteries, offering high energy density and long cycle life.

[0022] In this embodiment, the refrigeration box 201 is divided into an upper cooling cavity and a lower drying cavity by the refrigeration panel 205. The cooling member 203 for conveying cooling gas includes: The piston push plate 2031 is vertically installed in the upper cooling cavity.

The upper surface of the refrigeration box 201 is provided with a guide sliding block matched with the sliding hole. As the movable push plate 2033 moves, the drive gear 2035 is engaged with the upper rack 2034.

[0023] In this embodiment, preferably, the cooling component 203 also includes a driving motor 2036 fixed on the outer surface of the refrigeration box 201, and the front end of the driving motor 2036 is connected to a connecting rod 2037 that supports the driving gear 2035, and a stand is provided on the refrigeration box 201 to support the connecting rod 2037. Upper conduction plates 2032 are vertically provided inside the left cavity and the right cavity. The surface of the upper conduction plate 2032 is distributed with mesh holes, which does not affect the passage of gas, and the upper conduction plate 2032 is a metal plate with a relatively high conduction temperature coefficient, including but not limited to a copper plate, etc. The upper conduction plate 2032 is conveniently contacted with the refrigeration surface of the refrigeration plate 205, and conducts the temperature of the refrigeration surface, so that the upper conduction plate 2032 is cooled, which is convenient for cooling the gas passing through.

[0024] In this embodiment, preferably, the distribution pipe 202 includes: The left and right sides of the refrigeration box 201 are respectively provided with a second longitudinal tube 2025 and a first longitudinal tube 2022, and the inner wall of the refrigeration box 201 is provided with an adsorption plate 2038, which includes but is not limited to an activated carbon plate, for adsorbing the discharged cooling gas, and the second longitudinal tube 2025 and the first longitudinal tube 2022 are communicated with the left cavity and the right cavity respectively; a first switch valve 2024 is installed on the second longitudinal tube 2025 and the first longitudinal tube 2022, and the second longitudinal tube 2025 is connected to a plurality of U-shaped distribution pipes 2021 and is internally communicated; and two air inlet pipes are installed on the rear surface of the refrigeration box 201, and an air inlet valve can be provided on the air inlet pipe to facilitate The piston push plate 2031 moves to change the space of the left cavity or the right cavity, which is convenient for sucking gas through the air intake pipe, and a filter can be set inside the air intake pipe, and the two air intake pipes are connected to the left cavity and the right cavity respectively; multiple U-shaped distribution pipes 2021 are distributed on the outside of the battery module body 100, and the multiple U-shaped distribution pipes 2021 are evenly distributed longitudinally, which is convenient for expanding the blowing area of ​​the battery module body 100, and the inner surface of the U-shaped distribution pipe 2021 is provided with multiple nozzles 2023, and the multiple nozzles 2023 are distributed around the battery module body 100, and cooling gas can be introduced into gaps such as the battery joints, thereby improving the cooling and heat dissipation effect of the battery module body 100.

[0025] In summary, when in use, the drive motor 2036 works, driving the connecting rod 2037 and the driving gear 2035 to rotate, thereby driving the upper rack 2034 and the movable push plate 2033 engaged therewith to move to the left, driving the piston push plate 2031 to move to the left, the left chamber space gradually becomes smaller, and the right chamber space becomes larger. At this time, the first switch valve 2024 on the first longitudinal tube 2022 is closed, and the valve on the air inlet pipe connected to the right chamber is opened, and gas is introduced into the right chamber. The introduced gas is cooled in the right chamber by the upper conduction plate 2032 and the cooling surface of the refrigeration plate 205, and the first switch valve 2024 on the second longitudinal tube 2025 is opened, and the cooled gas in the left chamber passes through the second longitudinal tube 2025 into the multiple U-shaped distribution pipes 2021 and is ejected from the multiple nozzles 2023, acting on the surface of the battery module body 100. When the piston push plate 2031 moves to the left, the space in the right chamber becomes smaller. The space between the two cooling and adsorption structures 200 is gradually reduced, the left cavity sucks gas, and the right cavity is introduced with cooled gas and sprayed out through the nozzle 2023 to act on the surface of the battery module main body 100. If the two sets of cooling and adsorption structures 200 are symmetrically distributed, the working principles of the two are adjusted according to the moving direction of the piston push plate 2031. During the whole process, the gas can fully fill the gaps between the battery module main bodies 100 after cooling, and cool the gaps. There will be no situation where the surface of the battery module main body 100 is locally overheated and cannot be cooled down. While the refrigeration plate 205 cools the gas, the heat dissipation surface of the refrigeration plate 205 transfers the temperature to the components of the adsorption and drying component 204, and heats and regenerates the dry material filled in the lower drying chamber, reducing the saturation of the dry material, making it convenient for the dry material to continue to dry and adsorb the environment in which the battery module main body 100 is located, and will not let moisture affect the performance of the battery module main body 100 itself. Example 2

[0026] Reference Figure 6 and Figure 7 , which is the second embodiment of the present invention.

[0027] In this embodiment, preferably, an adsorption drying component 204 is provided to achieve adsorption drying of the environment in which the battery module body 100 is located while heating and regenerating the drying material, thereby reducing the saturation of the drying material and extending the moisture adsorption time. The drying material is shifted while being regenerated, thereby increasing the uniformity and sufficiency of the regeneration heating of the drying material. The adsorption drying component 204 for adsorption drying of the environment in which the battery module is located includes: Multiple lower conductive plates 2041 are vertically fixed inside the lower drying chamber. The lower conductive plates 2041 are in contact with the lower surface of the refrigeration plate 205. The lower conductive plates 2041 can be metal plates with a high temperature conductivity coefficient. Small holes are provided on the lower surface of the refrigeration box 201 to communicate with the lower drying chamber. The holes facilitate the drying material to absorb moisture from the environment in which the battery module body 100 is located. The lower drying chamber is filled with a drying material, which includes but is not limited to silica gel particles. A rotating rod 2042 is longitudinally passed through the plurality of lower conducting plates 2041. A plurality of material shifting rods 2043 are sleeved on the rotating rod 2042. The material shifting rods 2043 can rotate synchronously with the rotating rod 2042 to facilitate stirring of the dried material and facilitate sufficient heating and regeneration of the dried material. The transverse bevel gear 2046, the upper bevel gear 2047 and the lower bevel gear 2044 are installed between the outer end of the rotating rod 2042 and the connecting rod 2037. The rotating rod 2042 and the connecting rod 2037 rotate synchronously, which facilitates the discharge of cooling gas and can drive the connecting rod 2037 to rotate to stir the dry material.

[0028] In this embodiment, preferably, an upper bevel gear 2047 and a lower bevel gear 2044 are respectively provided on the connecting rod 2037 and the rotating rod 2042, a rotating shaft 2045 is vertically provided on the outside of the refrigeration box 201, a stabilizing plate 2048 supporting the rotating shaft 2045 is provided on the surface of the refrigeration box 201, and a bearing is embedded between the stabilizing plate 2048 and the rotating shaft 2045, and the upper and lower ends of the rotating shaft 2045 are respectively provided with transverse bevel gears 2046 that mesh with the upper bevel gear 2047 and the lower bevel gear 2044.

[0029] In summary, when in use, the heat dissipation surface of the refrigeration plate 205 transfers the temperature to the multiple lower conduction plates 2041. The lower conduction plates 2041 carry the temperature themselves and reheat the dry materials in contact with them. The small holes on the lower surface of the refrigeration box 201 allow the dry materials to absorb the moisture in the environment of the battery module body 100 at the same time. When the connecting rod 2037 rotates, it drives the upper bevel gear 2047 to rotate, drives the meshing transverse bevel gear 2046 located above to rotate, drives the rotating shaft 2045 to rotate, and drives the lower transverse bevel gear 2046 to rotate, thereby The lower bevel gear 2044 and the rotating rod 2042 meshing with it are driven to rotate, and the rotating rod 2042 drives the upper material-moving rod 2043 to rotate, moving the dry material in the lower drying chamber, so that the dry material is continuously turned and contacts the lower conductive plate 2041. The dry material absorbs moisture from the environment in which the battery module body 100 is located while being heated and regenerated by the lower conductive plate 2041, thereby reducing the saturation of the dry material, extending the time for the dry material to adsorb and dry the battery module body 100, reducing the impact of moisture on the use of the battery module body 100, and increasing the safety of the battery module body 100. Example 3

[0030] Reference Figure 8 and Figure 9 , which is the third embodiment of the present invention.

[0031] In this embodiment, preferably, a fire extinguishing structure 300 is provided on the side of the battery module body 100 for extinguishing fire. By providing the fire extinguishing structure 300, when the battery module body 100 is partially overheated or even sparks, the fire extinguishing structure 300 can be combined with the discharged cooling gas to accelerate the discharge rate of the fire extinguishing agent and expand the discharge range of the fire extinguishing agent, thereby expanding the fire extinguishing range of the overheated part of the battery module body 100 and increasing the safety of the battery module body 100. The fire extinguishing structure 300 includes: A storage box 302 is mounted on the side of the battery module body 100. An air inlet is provided on the rear surface of the lower end of the storage box 302. A piston plate 303 is horizontally arranged inside the storage box 302. A load-bearing block may be provided at the bottom of the piston plate 303 to facilitate downward movement and reset of the piston plate 303. A fire extinguishing agent is filled between the upper surface of the piston plate 303 and the storage box 302. Two traction ropes 306 are installed on the upper surface of the piston plate 303. A limit plate can be set on the traction rope 306, and a bellows is provided between the limit plate and the top of the storage box 302 to play a sealing role. The upper end of the traction rope 306 extends and is fixed to the inner end of the movable push plate 2033. The end of the movable push plate 2033 is provided with a fixed protrusion 301. The traction rope 306 is fixed to the surface of the fixed protrusion 301; A guide wheel 305 is installed on the outer surface of the refrigeration box 201 and supports and guides the traction rope 306. A horizontal plate supporting the guide wheel 305 is provided on the outer surface of the refrigeration box 201.

[0032] In this embodiment, preferably, a rotating member 304 is provided between the upper surface of the piston plate 303 and the inner wall of the upper end of the storage box 302. The rotating member 304 can move with the piston plate 303 while stirring the fire extinguishing agent, so that the fire extinguishing agent is in a loose state, which facilitates the rapid passage of the loose fire extinguishing agent into the feeding pipe 307. The rotating member 304 includes: A twisted rod 3041 fixed to the inner surface of the upper end of the storage box 302; The spiral tube 3042 is mounted on the upper surface of the piston plate 303, and the lower end of the twisted rod 3041 is spirally engaged with the spiral tube 3042, so that it rotates as the spiral tube 3042 moves upward; The spiral blades 3043 installed on the outer surface of the spiral tube 3042 facilitate the upward transportation of part of the fire extinguishing agent as the spiral tube 3042 rotates, so that the fire extinguishing agent can enter the feeding pipe 307. A feeding pipe 307 is provided between the storage box 302 and the distribution pipe 202. A switch valve is provided on the feeding pipe 307. When there is no overheating or fire, the switch valve on the feeding pipe 307 is closed.

[0033] In this embodiment, preferably, a chassis is provided on the upper surface of the piston plate 303 , and a bearing is embedded between the lower end of the spiral tube 3042 and the chassis to facilitate the rotation of the spiral tube 3042 .

[0034] In this embodiment, preferably, the lower end of the movable push plate 2033 is sleeved with a limit plate located outside the refrigeration box 201, and the movable push plate 2033 is sleeved with a sealing bellows 2039 fixed between the limit plate and the outer surface of the refrigeration box 201 to play a sealing role.

[0035] In summary, when it is necessary to extinguish the overheating or fire of the battery module main body 100, as the movable push plate 2033 moves to the left, the traction rope 306 moves around the guide wheel 305, drives the piston plate 303 to move upward, drives the spiral tube 3042 to move upward, and the spiral tube 3042 cooperates with the twisted rod 3041. The spiral tube 3042 drives the spiral blade 3043 to rotate, and the spiral blade 3043 rotates to transport the fire extinguishing agent upward. At this time, the switch valve on the feeding pipe 307 is closed. As the piston plate 303 moves upward a set distance, the fire extinguishing agent is pressurized. The gas in the left chamber has not been completely discharged. At this time, the switch valve on the feeding pipe 307 is opened again. As the piston plate 30 3 continues to move upward, and the gas in the left cavity continues to be discharged. The two together enter the U-shaped distribution pipe 2021 and are sprayed through multiple nozzles 2023 to act on the surface of the battery module body 100. The two work together to accelerate the discharge rate of the fire extinguishing agent, which is convenient for quickly extinguishing the fire of the battery module body 100. When the piston plate 303 moves, the spiral tube 3042 and the spiral blade 3043 rotate to accelerate the discharge of the fire extinguishing agent. After the fire is extinguished, as the connecting rod 2037 reverses, the piston plate 303 and the load-bearing block itself move downward under the action of gravity, and the piston plate 303 is reset, which is convenient for continued use next time. The whole process increases the fire extinguishing efficiency of the battery module body 100 and reduces safety hazards. Example 4

[0036] This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0037] During use, the cooling surface of the refrigeration plate 205 cooperates with the cooling component 203 to cool the surface of the battery module main body 100, and the cooled gas can act on the gaps of the battery module main body 100 to fully cool it down and expand the cooling area, so that there will be no local cooling problems. While cooling, the heat dissipation surface of the refrigeration plate 205 is used to heat and regenerate the dry material in the adsorption and drying component 204, and the dry material continues to adsorb and dry the moisture in the environment where the battery module main body 100 is located, extending the adsorption time. When there is no fire, as the cooling component 203 works, it can cooperate with the fire extinguishing structure 300 to continuously stir the fire extinguishing agent stored inside to avoid agglomeration, etc. When a fire occurs, it cooperates with the cooling component 203 to accelerate the spraying speed and area of ​​the fire extinguishing agent, expand the spraying range of the fire extinguishing agent, and more quickly extinguish the fire on the surface of the battery module main body 100.
