However, in actual use, the energy storage device will generate a lot of heat during operation.

[0011] Compared with the prior art, the present invention has the following beneficial effects: A high-efficiency quantum dot energy storage device employs a movable long plate mounted on the output shaft of a motor. Driven by the motor, the plate, along with a first sliding block fixedly connected at each end, slides horizontally along the outer surface of the first sliding rod. This not only enhances mobility but also ensures that the device slides along a predetermined trajectory. Simultaneously, a second sliding rod, located in a groove at the top of the first lifting column, drives the polygonal block in synchronous motion, facilitating the forward movement of the movable device fixed to the top of the polygonal block, away from the heat sink at the bottom of the energy storage cabinet, and toward the rear end of the cabinet for cooling air in different directions.

[0012] An energy storage device for high-efficiency quantum dots. A sliding wheel is arranged on a raised portion at the bottom of a polygonal block so that it can move synchronously with the polygonal block.

By arranging a first connecting block at the output shaft end of a cylinder, the first connecting block can quickly pull the second connecting block and the support plate fixedly connected at the top to perform synchronous movement. When the movable support plate pulls the rotating column movably connected to its raised part to move, the two ends of the rotating column will only move along the hollow track of the hollow block. Since the hollow part of the hollow block is provided with a curved track, under the drive of the cylinder, the rotating column will change direction along the curved path, thereby adjusting the blowing angle of the fan blades.

[0014] A device for storing high-efficiency quantum dots comprises support rods arranged on top of three first telescopic columns and a second support column. Driven by a motor, the support rods can be pushed outward to expand. When the outer surfaces of the three support rods are in close contact with the inner surface of an outer shell, the second lifting column moves upward under the support of a diamond plate.

Since the tops of the second lifting columns are connected to the inside of the outer shell, and the top of the outer shell is fixed to the bottom of an energy storage cabinet, when the second lifting columns push the outer shell upward, the bottom of the energy storage cabinet is lifted accordingly and moves toward the rear end for air blowing and heat dissipation.

[0019] Example 2: Based on Example 1, Figure 3-8As shown, the pushing device 21 includes a base plate 211, a motor 212 is provided at one end of the top of the base plate 211, and the top end of the base plate 211 is fixedly connected to the bottom of the motor 212, a movable long plate 213 is provided at the output shaft end of the motor 212, and the output shaft end of the motor 212 is correspondingly connected to one end of the bottom of the movable long plate 213, two first sliding blocks 214 are provided at both ends of the bottom of the movable long plate 213, and the two ends of the bottom of the movable long plate 213 are fixedly connected to the tops of the two first sliding blocks 214, and two first sliding rods 215 are provided at the bottom grooves of the four first sliding blocks 214. By arranging the movable long plate 213 at the output shaft end of the motor 212, under the drive of the motor 212, the movable long plate 213 together with the first sliding blocks 214 fixedly connected at both ends of the bottom will slide horizontally along the outer surface of the first sliding rod 215. This not only improves the movement flexibility, but also ensures that it slides along the predetermined track. At the same time, the second sliding rod 217, located in the groove at the top of the first lifting column 216, driven by the motor 212, drives the polygonal block 218 to move synchronously, thereby facilitating the forward movement of the movable device 22 fixed to the top of the polygonal block 218, away from the heat dissipation area at the bottom of the energy storage cabinet 1, and toward the rear end of the energy storage cabinet 1 to dissipate heat in a different direction. Furthermore, the grooves at the bottom of the four first sliding blocks 214 are all movably connected to the outer surfaces of the two first sliding rods 215.

The bottom of the movable device 22 is fixedly connected. Two sliding wheels 219 are provided on a raised portion at one end of the bottom of the polygonal block 218. These raised portions are movably connected to the two sliding wheels 219 on either side. By positioning the sliding wheels 219 on the raised portion at the bottom of the polygonal block 218, they can move synchronously with the polygonal block 218. When the outer surfaces of the sliding wheels 219 contact and slide with the highest point of the raised portion of the movable long board 213, the sliding wheels 219 push the top polygonal block 218 upward. Simultaneously, the four first lifting columns 216 located on the outer side of the movable long board 213 synchronously extend upward, assisting the movable device 22 connected to the top of the polygonal block 218 in achieving high-level airflow and heat dissipation after it is removed from the bottom of the energy storage cabinet 1. The outer surfaces of the two sliding wheels 219 are correspondingly connected to the raised portion at the other end of the top of the movable long board 213.

[0021] The movable device 22 includes a cylinder 221, the bottom of the cylinder 221 is fixedly connected to the top center of the polygonal block 218, the output shaft end of the cylinder 221 is provided with a first connecting block 222, and the output shaft end of the cylinder 221 is fixedly connected to the bottom of the first connecting block 222, the outer surface of the first connecting block 222 is provided with a placement plate 223, and the outer surface of the first connecting block 222 is correspondingly connected to the hollow part of the placement plate 223, the raised parts on both sides of the placement plate 223 are provided with hollow blocks 224, and the raised parts on both sides of the placement plate 223 are fixedly connected to the inner side of the hollow block 224.

[0022] A second connecting block 225 is provided on the top of the first connecting block 222, and the top of the first connecting block 222 is fixedly connected to the bottom of the second connecting block 225. A support plate 226 is provided on the top of the second connecting block 225, and the top of the second connecting block 225 is fixedly connected to the center of the bottom of the support plate 226. The raised parts at both ends of the top of the support plate 226 are provided with rotating columns 227, and the raised parts at both ends of the top of the support plate 226 are movably connected to the outer surface of the rotating column 227, and both ends of the rotating column 227 are movably connected to the hollow part of the hollow block 224. Two fan blades 228 are provided on the outer surface of the rotating column 227, and the outer surface of the rotating column 227 is connected to the raised parts of the two fan blades 228. Second sliding blocks 229 are provided on both ends of the bottom of the support plate 226, and the two ends of the bottom of the support plate 226 are connected to the first The two sliding blocks 229 are fixedly connected at the top, and the third sliding rod 2210 is provided in the groove at the bottom of each of the second sliding blocks 229. The groove at the bottom of each of the second sliding blocks 229 is movably connected to the outer surface of the third sliding rod 2210. By providing a first connecting block 222 at the output shaft end of the cylinder 221, the first connecting block 222 can quickly pull the second connecting block 225 fixed at the top and the support plate 226 to move synchronously. When the movable support plate 226 pulls the rotating column 227 movably connected to its raised portion, the two ends of the rotating column 227 will only move along the hollow track of the hollow block 224. Because the hollow portion of the hollow block 224 is provided with a curved track, under the drive of the cylinder 221, the rotating column 227 will change direction along the curved path, thereby adjusting the blowing angle of the fan blades 228. At the same time, the second sliding blocks 229 at the bottom ends of the support plate 226 will synchronously slide rapidly along the outer surface of the third sliding rod 2210, not only avoiding the jamming phenomenon that may occur during long-term use, but also effectively improving the adjustment speed. The bottoms of the two third sliding rods 2210 are fixedly connected to the top of the placement plate 223 .

[0023] The supporting device 32 includes three supporting rods 321, and the inner upper ends of the three supporting rods 321 are each provided with a first telescopic column 322 and a second supporting column 323, and the inner upper ends of the three supporting rods 321 are each fixedly connected to the top of the first telescopic column 322 and the second supporting column 323, and the bottoms of the three first telescopic columns 322 and the second supporting columns 323 are each provided with a fixing plate 324, and the bottoms of the three first telescopic columns 322 and the second supporting columns 323 are each fixedly connected to the front end of the fixing plate 324.

[0024] The three fixing plates 324 are provided with diamond plates 325 at the upper and lower ends, and the three fixing plates 324 are fixedly connected to the outer sides of the diamond plates 325 at the upper and lower ends. A second lifting column 326 is provided in the center of the two diamond plates 325. By arranging support rods 321 at the tops of the three first telescopic columns 322 and the second support columns 323, the support rods 321 can be pushed outward under the drive of the motor 212. When the outer surfaces of the three support rods 321 are tightly fitted with the inner surface of the shell 31, the second lifting columns 326 will move upward under the support of the diamond plates 325. At this time, the bottoms of the three support rods 321 will be perpendicular to the ground. Since the tops of the second lifting columns 326 are connected to the inside of the shell 31, and the top of the shell 31 is fixed to the bottom of the energy storage cabinet 1, when the second lifting columns 326 push the shell 31 upward, the bottom of the energy storage cabinet 1 is lifted accordingly. This not only enhances the air circulation at the bottom, but also cooperates with the pushing device 21 to slide out from the bottom and move to the rear end for blowing and heat dissipation. The centers of the two diamond-shaped plates 325 are fixedly connected to the outer surface of the second lifting column 326 , and the top of the second lifting column 326 is connected to the top of the inner surface of the shell 31 .

[0025] The working principle of the present invention is as follows: When the quantum dot material within the energy storage cabinet 1 generates heat during the charging and discharging process, the system initiates a heat dissipation process: the pushing device 21 includes a motor 212. Once activated, the motor 212 drives the movement of the movable long plate 213 connected to its output shaft. Because the bottom ends of the movable long plate 213 are connected to the first sliding block 214, the first sliding block 214 can only achieve stable horizontal sliding under the constraint of the first sliding rod 215. At the same time, the second sliding rod 217 in the groove at the top of the first lifting column 216, driven by the secondary drive of the motor 212, drives the polygonal block 218 to move. At this time, the sliding wheel 219 at the bottom of the polygonal block 218 contacts the highest point of the raised portion at the top of the moved movable long plate 213, thereby pushing the polygonal block 218 up. The four first lifting columns 216 on the outside also extend upward synchronously with the polygonal block 218, shifting the movable device 22 connected to the top of the polygonal block 218 from the heat dissipation position at the bottom of the energy storage cabinet 1 to a forward position for blowing air. After the cylinder 221 of the movable device 22 is started, it will drive the movement of the first connecting block 222 connected to its output shaft, and then drive the second connecting block 225 and the support plate 226 to move synchronously. Since the two ends of the rotating column 227 of the raised part of the support plate 226 are movably connected to the hollow part of the hollow block 224, and the hollow part of the hollow block 224 is provided with a curved track, under the drive of the cylinder 221, the rotating column 227 will only move along the curved path, thereby changing the blowing angle of the fan blade 228. At the same time, the second sliding block 229 at the bottom of the support plate 226 will slide quickly along the third sliding rod 2210 to ensure the smoothness and efficiency of the angle adjustment of the fan blade 228. Through the mutual cooperation of the pushing device 21 and the movable device 22, the fan blade 228 can blow and dissipate heat at different positions on the rear end or bottom vent of the energy storage cabinet 1, thereby enhancing the heat dissipation effect; The support device 32 in the lifting device 3 is driven by the motor 212, and the three first telescopic columns 322 and the second support column 323 will continuously push the support rod 321 fixedly connected at the top to expand outward. When the outer surface of the support rod 321 is tightly fitted with the inner surface of the outer shell 31, the second lifting column 326 will move upward under the support of the diamond plate 325, and at this time the bottom of the three support rods 321 will be perpendicular to the ground. Since the top of the second lifting column 326 is connected to the inside of the outer shell 31, and the top of the outer shell 31 is fixed to the bottom of the energy storage cabinet 1, when the second lifting column 326 pushes the outer shell 31 upward, the bottom of the energy storage cabinet 1 is lifted accordingly. After the energy storage cabinet 1 is lifted, the ventilation space at the bottom will be increased, the air circulation will be smoother, and the heat dissipation efficiency will be further improved in conjunction with the air blowing of the heat dissipation device 2; Through the mutual cooperation of these devices, the performance degradation problem caused by heat accumulation in the quantum dot energy storage system can be effectively solved, the service life of the quantum dot material can be extended, and the overall efficiency and stability of the energy storage device can be improved.
