In order to facilitate the movement and assembly and disassembly of the large-volume and large-mass battery pack, a plurality of battery pack moving wheels 22 are provided below the battery pack 21 to perform the movement and transportation of the battery pack 21 by the rotation of the battery pack moving wheels 22. When the energy storage battery pack 2 enters the battery pack mounting layer 11 from the opening of the battery pack mounting layer 11, the battery pack moving wheel 22 is located on the battery mounting and dismounting rail 111 and can rotate on the battery mounting and dismounting rail 111, so that the battery pack 21 can be moved to a proper position on the battery pack mounting layer 11, and an electrode interface on the battery pack 21 can be connected with an electrode interface of the energy storage battery pack 2 on the energy storage battery mounting frame 1, so that a plurality of energy storage battery packs 2 are mutually combined into an integral energy storage power supply module.
The battery wheel grooves 1111 can be further formed in the battery mounting and dismounting rails 111, the width of the battery wheel grooves 1111 is slightly larger than that of the battery pack moving wheels 22, and the distance between the battery wheel grooves 1111 in the battery mounting and dismounting rails 111 on two sides of the battery mounting frame 1 is the same as the distance between the battery pack moving wheels 22 on two sides of the energy storage battery pack 2. When the energy storage battery pack 2 is attached to or detached from the battery pack attachment layer 11, the battery pack moving wheel 22 moves in the battery wheel groove 1111, so that the left-right movement of the energy storage battery pack 2 can be restricted, and the energy storage battery pack 2 is kept in a fixed position on the battery mounting frame 1.
The battery positioning device 112 arranged at the set position on the battery mounting and dismounting track 111 can limit the free rotation of the battery pack moving wheel 22 and change the height of the battery pack moving wheel 22 on the battery mounting and dismounting track 111, so that the bottom surface of the battery pack 21 is contacted with the battery heat dissipation device 113, thereby taking away the heat generated by charging and discharging the battery pack 21 through the battery heat dissipation device 113 and keeping the battery pack 21 at a proper working temperature.
In some embodiments of the combined energy storage power supply module of the present application, as shown in fig. 3-5, the battery positioning device 112 includes a moving wheel guide slot 1121 and a moving wheel positioning slot 1122. The moving wheel guide slot 1121 is obliquely arranged, when the battery pack moving wheel 22 reaches the position of the moving wheel guide slot 1121, the battery pack moving wheel 22 can slide forwards along the moving wheel guide slot 1121 under the gravity action of the battery pack 21, and meanwhile, the height of the battery pack moving wheel 22 is gradually reduced in the process that the battery pack moving wheel 22 slides along the moving wheel guide slot 1121, so that the bottom surface of the battery pack 21 is gradually close to the battery heat dissipation device 113.
The moving wheel positioning groove 1122 is connected to the end of the moving wheel guide groove 1121 and has the same height as the end of the moving wheel guide groove 1121 or a height slightly lower than the end of the moving wheel guide groove 1121 so that the battery pack moving wheel 22 rotating along the moving wheel guide groove 1121 must reach into the moving wheel positioning groove 1122 and the battery pack moving wheel 22 is restrained in the moving wheel positioning groove 1122. At this time, the battery pack moving wheel 22 is at the lowest position of the battery positioning device 112, and in this position state, the bottom surface of the battery pack 21 can be reliably contacted with the battery heat dissipating device 113, so that the battery pack 21 can be better dissipated by the battery heat dissipating device 113.
The inclination of the moving wheel guide groove 1121 is set small so that the battery pack moving wheel 22 can rotate at a slow speed in the moving wheel guide groove 1121, thereby reducing vibration caused when the battery pack moving wheel 22 reaches the moving wheel positioning groove 1122 and also reducing impact of the battery pack 21 on the battery heat sink 113. A layer of heat conducting pad can be further arranged on the battery heat dissipation device 113, so that on one hand, impact of the battery pack 21 on the battery heat dissipation device 113 when the energy storage battery pack 2 is installed is reduced, on the other hand, heat conduction between the battery pack 21 and the battery heat dissipation device 113 can be further enhanced, and heat dissipation performance of the battery pack 21 is improved.
When the energy storage battery pack 2 needs to be detached from the battery pack mounting layer 11, the energy storage battery pack 2 is pushed towards the opening direction of the battery pack mounting layer 11, and the battery pack moving wheel 22 can overcome the gravity of the battery pack 21 under the action of the pushing force, leave the moving wheel positioning groove 1122 and move upwards along the slope of the moving wheel guiding groove 1121. In the moving process of the battery pack moving wheel 22, the height of the battery pack moving wheel 22 is gradually raised to drive the bottom surface of the battery pack 21 to be gradually raised and gradually separated from the battery heat dissipation device 113. When the battery pack moving wheel 22 leaves the battery positioning device 112, the distance between the bottom surface of the battery pack 21 and the battery heat dissipation device 113 reaches a proper safety distance, so that scraping between the battery pack 21 and the battery heat dissipation device 113 is prevented, and the assembly and disassembly safety of the energy storage battery pack 2 is ensured. The small inclined slope of the moving wheel guide slot 1121 can reduce the resistance of the battery pack moving wheel 22 when the battery pack moving wheel moves up along the moving wheel guide slot 1121, so that the battery pack 2 can be taken out conveniently.
In a preferred embodiment of the combined energy storage power module of the present application, as shown in fig. 4 and 5, the battery pack moving wheel 22 includes a first moving wheel 221 at the front end of the energy storage battery pack 2 and a second moving wheel 222 at the rear end of the energy storage battery pack 2.

When the energy storage battery pack 2 is mounted on the battery pack mounting layer 11, the first moving wheel 221 first reaches the battery mounting/dismounting rail 111, moves along the battery mounting/dismounting rail 111 to the depth of the battery pack mounting layer 11, and the second moving wheel 222 reaches the battery mounting/dismounting rail 111 again, and moves along the battery mounting/dismounting rail 111 to the depth of the battery pack mounting layer 11.
The battery positioning device 112 is disposed at the mounting position of the energy storage battery pack 2 on the battery pack mounting layer 11, at the position corresponding to the first moving wheel 221 on the battery mounting/dismounting rail 111, and at the position corresponding to the second moving wheel 222, wherein the battery positioning device 112 corresponding to the first moving wheel 221 is a first battery positioning device, and the battery positioning device 112 corresponding to the second moving wheel 222 is a second battery positioning device. The width of the first moving wheel 221 is smaller than the width of the moving wheel guide groove 1121 and the width of the moving wheel guide groove 1122 of the first battery positioner, so that the first moving wheel 221 can enter the moving wheel guide groove 1121 and the moving wheel guide groove 1122 of the first battery positioner when the first moving wheel 221 moves to the first battery positioner position along the battery attaching/detaching rail 111; the width of the second moving wheel 222 is smaller than the width of the moving wheel guide groove 1121 and the width of the moving wheel guide groove 1122 of the second battery positioner, so that the second moving wheel 222 can enter the moving wheel guide groove 1121 and the moving wheel guide groove 1122 of the second battery positioner when the second moving wheel 222 moves to the second battery positioner position along the battery mounting and dismounting rail 111; and the width of the first moving wheel 221 is greater than the width of the moving wheel guide slot 1121 and the width of the moving wheel positioning groove 1122 of the second battery positioning device, when the first moving wheel 221 moves along the battery mounting and dismounting rail 111 from the opening of the battery pack mounting layer 11 to the first battery positioning device position, the first moving wheel 221 must first pass through the second battery positioning device position, and the setting of the width of the first moving wheel 221 greater than the width of the moving wheel guide slot 1121 and the width of the moving wheel positioning groove 1122 of the second battery positioning device can prevent the first moving wheel 221 from entering the moving wheel guide slot 1121 and the moving wheel positioning groove 1122 of the second battery positioning device, so that the first moving wheel 221 can smoothly and steadily reach the first battery positioning device position.
