Photovoltaic energy storage system usually consists of two parts: photovoltaic power generation system and energy storage system. Photovoltaic power generation system converts light energy into electrical energy through solar photovoltaic panels, and then converts direct current into alternating current through inverters, and supplies it to electrical equipment. The composition of photovoltaic power generation system includes photovoltaic panels, brackets, cables, inverters, etc.; energy storage system is used to store the electricity generated by photovoltaic power generation so as to supply electricity when solar energy is not available or during peak demand periods.

[0049] Please refer to the attached manual Figure 1-11 , a photovoltaic energy storage battery device provided by an embodiment of the present invention comprises a plurality of energy storage batteries 1 and a battery box 2, wherein the plurality of energy storage batteries 1 are located in the battery box 2, two battery columns 6 are installed on the top side of the energy storage battery 1, and a plurality of auxiliary heat dissipation holes 7 are opened on both sides of the battery box 2;

[0050] And it also includes an active heat dissipation mechanism 3, the active heat dissipation mechanism 3 is installed in the battery box 2, and multiple energy storage batteries 1 are all installed in the active heat dissipation mechanism 3, and the active heat dissipation mechanism 3 helps the energy storage batteries 1 to dissipate heat; specifically, the active heat dissipation mechanism 3 includes multiple heat dissipation sleeves 301, the multiple heat dissipation sleeves 301 are all located in the battery box 2, the multiple heat dissipation sleeves 301 are all filled with heat dissipation oil, and the multiple energy storage batteries 1 are respectively inserted into the multiple heat dissipation sleeves 301, and a connecting pipe 302 is connected between two adjacent heat dissipation sleeves 301. The two outermost heat dissipation sleeves 301 are respectively connected to a liquid outlet pipe 303 and an extraction pump 305, and the liquid outlet pipe 303 and the extraction pump 305 are both connected to a stretching pipe 306. A heat dissipation pipe 304 is connected between the two stretching pipes 306, and a protective box 318 is sleeved on the heat dissipation pipe 304, and the protective box 318 is buried underground.

[0051] It should be noted that, in the embodiment of the present invention, by setting the active heat dissipation mechanism 3, when the energy storage battery 1 is placed in the heat dissipation sleeve 301, since the heat dissipation pipe 304 is buried underground, the heat dissipation oil is cooled by the cool air underground, and then the extraction pump 305 is started to extract the heat dissipation oil into the heat dissipation sleeve 301, and the heat dissipation oil in other positions is continuously pushed into the heat dissipation pipe 304 to realize the circulation of the heat dissipation oil, thereby realizing the effective heat dissipation of the energy storage battery 1 with the help of the natural cool air underground; in addition, by setting the stretching tube 306, the depth of the protection box 318 buried underground can be adjusted according to the actual installation situation to ensure that the heat dissipation pipe 304 is effectively cooled, and at the same time, when the energy storage battery 1 has a short circuit or fire problem, the heat dissipation sleeve 301 can be melted, and the outflowing heat dissipation oil can extinguish the fire and insulate the energy storage battery 1, thereby avoiding the problem of continuous damage to multiple energy storage batteries caused by a problem with one energy storage battery 1.

[0052] Furthermore, a photovoltaic energy storage battery device provided by an embodiment of the present invention also includes a rainwater collection mechanism 4, which is installed on the active heat dissipation mechanism 3, and is used to collect rainwater and assist the active heat dissipation mechanism 3 in heat dissipation; specifically, the rainwater collection mechanism 4 includes a collecting box 401, and the bottom side of the collecting box 401 is connected to a regulating pipe 402, and the bottom end of the regulating pipe 402 is connected to a water inlet pipe 403, and the water inlet pipe 403 is connected to the protective box 318. The collecting box 401 is used to collect rainwater and transport the rainwater to the protective box 318. It should be noted that, through the setting of the rainwater collection mechanism 4, when the battery box 2 is in use, rainwater is collected in the collection box 401 by the collection cover 404, and when the rainwater reaches a certain weight, the rebound sealing plate 406 is squeezed to open, and the return torsion spring 408 is driven to be stressed, so that the rainwater can enter the water inlet pipe 403 through the regulating tube 402, and then enter the protection box 318 through the water inlet pipe 403. Therefore, the dual heat dissipation of water and underground cool air further helps the heat dissipation oil to dissipate heat, thereby further ensuring the heat dissipation effect of the energy storage battery 1; in addition, when the rainwater decreases, under the reset force of the return torsion spring 408, the top side of the rebound sealing plate 406 is helped to contact with the blocking ring 405, so that the collection box 401 is sealed to prevent water vapor from evaporating.

[0053] Furthermore, a photovoltaic energy storage battery device provided by an embodiment of the present invention further includes an active sealing mechanism 5, which is installed outside the battery box 2 and is used to seal the battery box 2; specifically, the active sealing mechanism 5 includes two sealing plates 501, and a plurality of connecting air outlets 502 are provided on the sealing plates 501, and the connecting air outlets 502 are connected to the auxiliary heat dissipation holes 7, and filter plates 514 are installed on the inner walls of both sides of the battery box 2, and the plurality of auxiliary heat dissipation holes 7 on the same side are all located in the filter plates 514. It should be noted that, through the setting of the active sealing mechanism 5, since the energy storage battery 1 needs to dissipate heat when in use, the connection between the sealing plate 501 and the auxiliary heat dissipation holes 7 is used to achieve air circulation, which helps the energy storage battery 1 to perform auxiliary heat dissipation. However, in windy and sandy weather, if the battery box 2 is not closed in time, a large amount of sand and dust will be filled in the battery box 2, causing the energy storage battery 1 to be unable to dissipate heat. At the same time, in strong convective weather, if the battery box 2 is not closed in time, a large amount of water will enter the battery box 2, causing problems such as short circuits;

[0054] Therefore, in the embodiment of the present invention, in sandstorm weather, strong wind blows the carrying box 507, causing the carrying box 507 to shake, and then drives the shaking ball 509 to shake through the connecting rod 510, and the shaking ball 509 shakes in the spherical groove 508, so that the carrying box 507 squeezes the lower pressure frame 511 to move; or in strong convective weather, the water in the carrying box 507 is quickly filled, and because the bottom inner wall of the carrying box 507 is inclined, it will also drive the carrying box 507 to swing, and then squeeze the lower pressure frame 511 to move, and the lower pressure frame 511 is in the four limiting slide grooves 512. The battery box 2 slides vertically inside and drives the two adapter frames 513 to move. The movement of the adapter frames 513 drives the two closing plates 501 to move, so that the closing plates 501 close the multiple auxiliary heat dissipation holes 7, thereby ensuring the sealing of the battery box 2, thereby preventing dust or water from entering the battery box 2, thereby ensuring the safe use of the energy storage battery 1; in addition, the movement of the closing plate 501 drives the two return springs 504 to be stressed, so when the external obstacles disappear, the rebound force of the return springs 504 can help the closing plate 501 to reset, thereby allowing the battery box 2 to automatically return to the heat dissipation state.

[0064] More specifically, in the embodiment of the present invention, two adapter frames 513 are installed on the lower pressing frame 511, and the two adapter frames 513 are respectively installed on the two closing plates 501. It should be noted that in the embodiment of the present invention, when the lower pressing frame 511 moves, the two adapter frames 513 are driven to move, thereby realizing the lifting and lowering of the closing plate 501.

[0065] Please continue to refer to the instruction manual Figure 2-3 and Figure 9-11 , more specifically, in the embodiment of the present invention, side plates 503 are installed on both sides of the battery box 2, two return springs 504 are installed on the side plates 503, and the top ends of the return springs 504 are installed on the bottom side of the closing plate 501;

[0066] In addition, a rubber sleeve 505 is sleeved on the return spring 504, and the top side of the rubber sleeve 505 is mounted on the bottom side of the closing plate 501, and the bottom side of the rubber sleeve 505 is mounted on the side plate 503. It should be noted that in the embodiment of the present invention, the movement of the closing plate 501 drives the two return springs 504 to be stressed, so when the external obstacles disappear, the return spring 504 can help the closing plate 501 to reset, thereby allowing the battery box 2 to automatically return to the heat dissipation state; in addition, the rubber sleeve 505 can protect the return spring 504 to prevent it from being corroded by water vapor and rusted.

[0067] In summary, the working principle of a photovoltaic energy storage battery device provided by an embodiment of the present invention is:

[0068] When the energy storage battery 1 is placed in the heat dissipation sleeve 301, since the heat dissipation pipe 304 is buried underground, the heat dissipation oil is cooled by the cool air underground, and then the extraction pump 305 is started to extract the heat dissipation oil into the heat dissipation sleeve 301, and the heat dissipation oil in other positions is continuously pushed into the heat dissipation pipe 304 to realize the circulation of the heat dissipation oil, thereby achieving effective heat dissipation of the energy storage battery 1 with the help of the natural cool air underground; and through the setting of the stretching tube 306, the depth of the protection box 318 buried underground can be adjusted according to the actual installation situation to ensure that the heat dissipation of the heat dissipation pipe 304 is effectively achieved. It should be noted that, when the energy storage battery 1 has a short circuit or catches fire, the heat dissipation sleeve 301 can be melted, and the heat dissipation oil that flows out can extinguish the fire and insulate the energy storage battery 1, so as to avoid the problem that a problem of one energy storage battery 1 causes continuous damage to multiple energy storage batteries; in addition, when installing the energy storage battery 1, under the resilience of the two reset springs 313, the two pull-down frames 312 are driven to move upward, and then the bottom frame 311 is driven to move upward, so that the energy storage battery 1 can be placed in multiple heat dissipation sleeves 301 in sequence, and then the pull-down frame 312 is pressed to force the reset spring 313, and then the bottom frame 311 drives the multiple heat dissipation sleeves 301 to move downward, and at this time, the two locking frames 314 are released, and under the resilience of the pull-back spring 317, the locking frames 314 are reset and inserted into the two connecting plates 307, so that the installation of the energy storage battery 1 can be completed conveniently;

[0069] Furthermore, when the battery box 2 is in use, rainwater is collected in the collection box 401 by the collection cover 404, and when the rainwater reaches a certain weight, the rebound sealing plate 406 is squeezed to open, and the return torsion spring 408 is driven to bear force, so that the rainwater can enter the water inlet pipe 403 through the regulating pipe 402, and then enter the protection box 318 through the water inlet pipe 403. Therefore, the dual heat dissipation of water and underground cool air further helps the heat dissipation oil to dissipate heat, which can further ensure the heat dissipation effect of the energy storage battery 1; in addition, when the rainwater decreases, under the reset force of the return torsion spring 408, the top side of the rebound sealing plate 406 is helped to contact the blocking ring 405, so that the collection box 401 is sealed to prevent water vapor from evaporating;

[0070] Furthermore, since the energy storage battery 1 needs to dissipate heat when in use, the air circulation is achieved by connecting the closing plate 501 with the auxiliary heat dissipation hole 7, thereby helping the energy storage battery 1 to dissipate heat. However, in windy and sandy weather, if the battery box 2 is not closed in time, a large amount of sand and dust will be filled in the battery box 2, causing the energy storage battery 1 to be unable to dissipate heat. At the same time, in strong convection weather, if the battery box 2 is not closed in time, a large amount of water will enter the battery box 2, causing problems such as short circuit.

[0071] Therefore, it is necessary to further explain that, in sandstorm weather, strong wind blows the carrying box 507, causing the carrying box 507 to shake, and then drives the shaking ball 509 to shake through the connecting rod 510, and the shaking ball 509 shakes in the spherical groove 508, so that the carrying box 507 squeezes the lower pressure frame 511 to move, or in strong convective weather, the water in the carrying box 507 is quickly filled, and because the bottom inner wall of the carrying box 507 is inclined, it will also drive the carrying box 507 to swing, and then squeeze the lower pressure frame 511 to move, and the lower pressure frame 511 is in the four limiting slide grooves 51 2, and drives the two adapter frames 513 to move, and the movement of the adapter frames 513 drives the two closing plates 501 to move, so that the closing plates 501 close the multiple auxiliary heat dissipation holes 7, thereby ensuring the sealing of the battery box 2, thereby preventing dust or water from entering the battery box 2, thereby ensuring the safe use of the energy storage battery 1; in addition, the movement of the closing plates 501 drives the two return springs 504 to be stressed, so when the external obstacles disappear, the rebound force of the return springs 504 can help the closing plates 501 to reset, thereby allowing the battery box 2 to automatically return to the heat dissipation state.
