From the above, we can know that:

The utility model is aimed at the following technical problems: In the process of using the existing technology, due to the large size of energy storage batteries for new energy sources such as solar energy and wind energy, passive heat dissipation is performed by using heat dissipation fins, which has an unsatisfactory heat dissipation and cooling effect on the energy storage batteries, and the protection of the energy storage batteries is not comprehensive enough; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

During use, when the battery pack 1 needs to be cooled and dissipated, the semiconductor refrigeration sheet 8, the fan 9 and the pump 10 are connected to the battery pack 1, and then the semiconductor refrigeration sheet 8, the fan 9 and the pump 10 are started. The cooling end of the semiconductor refrigeration sheet 8 cools the air, and the input end of the pump 10 transmits the cold air to the conveying pipe rack 11 through the output end, and finally discharges the cold air through the hollow air hole plate 12 to the outside of the battery pack 1 for cooling. The heat generated by the heat dissipation end of the semiconductor refrigeration sheet 8 is discharged by the fan 9 and discharged to the outside through the filter plate 13. At the same time, the hot air in the placement slot 5 is discharged into the heat dissipation slot 6 through the ventilation hole, forming a ventilation refrigeration cycle, realizing the heat dissipation and cooling of the battery pack 1, and ensuring the normal operation of the battery pack 1;

When the battery pack 1 needs to be fixed, the protective cover 3 is first connected to the protective shell 2 by screws. At this time, the battery pack 1 is completely wrapped to form protection. Then the rotating rod 14 is rotated, and the rotating rod 14 drives the wheel 15 to rotate. Because the arc groove 17 is slidably connected with the sliding rod 18, the sliding rod 18 is fixed to the T-shaped plate 20, and the T-shaped plate 20 is slidably connected to the limiting groove 21, the arc groove 17 can push the T-shaped plate 20 to move downward along the inner side of the limiting groove 21 through the sliding rod 18 until the pressure rod 19 drives the lower pressure plate to press on the battery pack 1, and then the threaded rod 22 is rotated so that the threaded rod 22 is connected to the corresponding screw hole 23 to fix the battery pack 1 and prevent the battery pack 1 from shaking.

Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

1. The utility model uses the structural design of the heat dissipation mechanism to facilitate the device to dissipate heat and cool the battery pack 1, thereby ensuring the suitability of the environment in which the battery pack 1 is located and improving the safety of the device.

2. The utility model adopts the structural design of the positioning mechanism so that the device can fix and limit the battery pack 1. At the same time, the protective shell 2 and the protective cover 3 can fully protect the battery pack 1 to prevent the battery pack 1 from being hit by the outside, thereby achieving a good protective effect.
