The cooling circulation mechanism includes multiple partitions 4, which are all fixedly embedded inside the heat sink 2. The bottom of the heat sink 2 is fixedly connected to an air collection box 5, and the top of the air collection box 5 is provided with an air outlet slot 6. The cooling circulation mechanism also includes multiple positioning tubes 7, all of which are fixedly connected to the top of the air collection box 5; To achieve the heat dissipation and cooling effect, this device adopts the following technical solution: An air pump 8 is located at the rear of the heat dissipation box 2. A first exhaust pipe 9 is located on one side of the air pump 8, and a connecting pipe 10 is fixedly connected to the bottom of the first exhaust pipe 9. Two round pipes 11 are located on both sides of the air collection box 5, with their outer ends extending to the outside of the air collection box 5. The round pipes 11 are connected to the connecting pipe 10. A second exhaust pipe 12 is located at the other end of the air pump 8. A heat dissipation box 13 is located at the rear of the heat dissipation box 2. The second exhaust pipe 12 is connected to the bottom of the heat dissipation box 13. A flexible hose 14 is fixedly connected to the top of the heat dissipation box 13, and the flexible hose 14 is connected to the cover plate 3.

The output ends of each servo motor 18 are fixedly connected to a drive shaft 19. Each drive shaft 19 is fixedly fitted with a first sprocket 20. Each cooling box 17 has a through groove at the top and bottom. Each of the two bottom through grooves is fitted with a filter screen. Each of the two top through grooves is fitted with a fan blade 21. Each of the two fan blades 21 is fixedly fitted with a drive rod 22. A second sprocket 23 is fixedly fitted on the top of the drive rod 22. A chain 24 is fitted on the outer side of the first sprocket 20 and the second sprocket 23. The first sprocket 20 and the second sprocket 23 are driven and connected by the chain 24. Each cooling box 17 has a positioning frame 25 on its top. The positioning frame 25 is fitted on the outer side of the drive rod 22 and is movably connected to the drive rod 22 through a rolling bearing. When the user starts the air pump 8, the air pump 8 circulates the air inside the protective cover. When the air enters the protective cover through the air outlet 6, it cools the bottom of the energy storage battery body 1. Then, the air blows upward through the multiple partitions 4 to cool the outside of the protective cover. Then, the air passes through the hose 14 and the heat dissipation box 13 to cool the air. Then, it enters the heat dissipation box 2 through the air outlet 6 again for recirculation and cooling. When the hot air passes through the heat dissipation box 13, the multiple heat absorption racks 15 absorb the heat. The absorbed heat is discharged into the cooling box 17 through the heat dissipation copper fins 16. When the servo motor 18 is working, it drives the drive shaft 19 and the first sprocket 20 to rotate. The rotation of the first sprocket 20 drives the second sprocket 23 and the drive rod 22 to rotate. The rotation of the drive rod 22 drives the fan blades 21 to rotate.

The telescopic stop block 31 is provided with a spring-loaded structure inside. When the cover plate 3 is closed, the energy storage battery body 1 presses down multiple lifting rods 26, causing the lifting rods 26 to penetrate into the positioning tube 7 and be embedded into the locking groove through the locking rod 30, making the structure stable. At the same time, when the cover plate 3 is opened, multiple springs 27 spring up, causing the lifting rods 26 to move upward, thereby lifting the energy storage battery body 1, making it easy for the user to remove the energy storage battery body 1. The usage process of this invention is as follows: The user starts the air pump 8, which circulates the air inside the protective cover. When the air enters the protective cover through the air outlet 6, it dissipates heat from the bottom of the energy storage battery body 1. Then, the air blows upward through the multiple partitions 4, dissipating heat from the outside of the protective cover. The air then passes through the hose 14 and the heat dissipation box 13 for further cooling, and then re-enters the heat dissipation chamber 2 through the air outlet 6 for recirculation. When the hot air passes through the heat dissipation box 13, multiple heat absorption racks 15 absorb the heat. The absorbed heat is then discharged into the cooling box 17 through the heat dissipation copper fins 16. When the servo motor... When the machine 18 is working, it drives the drive shaft 19 and the first sprocket 20 to rotate. The rotation of the first sprocket 20 drives the second sprocket 23 and the drive rod 22 to rotate. The rotation of the drive rod 22 drives the fan blade 21 to rotate. The rotation of the fan blade 21 carries away the heat of the cooling box 17, achieving the effect of heat dissipation. When the cover plate 3 is closed, the energy storage battery body 1 presses down multiple lifting rods 26, so that the lifting rods 26 penetrate into the positioning tube 7 and are embedded into the locking groove through the locking rod 30, making the structure stable. At the same time, when the cover plate 3 is opened, multiple springs 27 spring up, causing the lifting rods 26 to move upward, thereby lifting the energy storage battery body 1, making it easy for the user to remove the energy storage battery body 1.
