[0001] The present invention relates to the technical field of energy storage batteries, and particularly relates to a stacked energy storage battery. Background Art

[0002] With the continuous progress and development of lithium battery technology and its gradual application in social production and life, energy storage batteries are becoming more and more widely used. However, the requirements for energy storage are getting higher and higher. In actual use, series and parallel connections are made according to requirements to meet the usage requirements. At this time, multiple batteries will be stacked together for use.

[0003] In the prior art, the stacking of energy storage batteries is generally vertical palletizing. The gaps between adjacent energy storage batteries are relatively small, which is not conducive to the heat dissipation of the batteries. Moreover, during the process of moving and using, it is easy for adjacent energy storage batteries to collide, posing a risk of explosion and damage. And after stacking, generally, screws are used to drive the clamping plate to move and clamp, which is relatively cumbersome in operation. And this stacking method will exert a relatively large pressure on the bottom battery when the stacking quantity is too large, causing battery damage.

[0004] The inventor proposes a stacked energy storage battery to improve the technical problems described above. Summary of the Invention

The inner walls of the four annular grooves are all slidably connected with rotatable toothed rings. The inner side walls of the four toothed rings are all fixedly connected with two mounting plates. The mounting plates are in a U shape. An energy storage battery body is arranged inside the two mounting plates. Strip-shaped cavities are opened in the mounting plates. The inner walls of the strip-shaped cavities are hermetically slidably connected with first plates.

Embodiment

[0022] Refer to Figure 1-9 , a stacked energy storage battery, including the following structure: Box body 1, four installation round holes 2 are opened on the side wall of box body 1, and a fixed frame 19 is fixedly connected to the side wall of box body 1 near the four installation round holes 2, and a cooling fan 20 is installed on the inner wall of fixed frame 19.

[0023] The installation mechanism includes four annular grooves 3 respectively opened in four installation round holes 2. The inner walls of the four annular grooves 3 are all slidably connected with rotatable toothed rings 4. The inner side walls of the four toothed rings 4 are all fixedly connected with two installation plates 5. The installation plates 5 are in a U shape. An energy storage battery body 10 is arranged in the two installation plates 5. Strip-shaped cavities 6 are opened in the installation plates 5. The inner wall of the strip-shaped cavity 6 is hermetically slidably connected with a first plate �. The side wall of the first plate 7 far from the toothed ring 4 is fixedly connected with a plurality of first rods 8. The side walls of the plurality of first rods 8 hermetically penetrate through the inner wall of the strip-shaped cavity 6 and are jointly fixedly connected with a clamping plate 9. The mutually adjacent side walls of the two clamping plates 9 are respectively abutted against the two side walls of the energy storage battery body 10.

[0024] A pressing mechanism is arranged on the box body 1. The pressing mechanism includes an oil storage tank 13 fixedly connected to the side wall of the box body 1. The oil storage tank 13 is located in the fixed frame 19. The inner bottoms of the four installation round holes 2 are all fixedly connected with rotary joints 11 through brackets. The inner walls of the mutually adjacent two strip-shaped cavities 6 are jointly fixedly communicated with a U-shaped pipe 12. The inner wall of the U-shaped pipe 12 is fixedly communicated with one side of the rotary joint 11. The other side of the rotary joint 11 is fixedly communicated with the inner wall of the oil storage tank 13 through an L-shaped pipe 14.

[0025] The inner wall of the oil storage tank 13 is hermetically slidably connected with a second plate 15. The side wall of the oil storage tank 13 far from the box body 1 is fixedly connected with an electric push rod 18. The movable end of the electric push rod 18 is fixedly connected with a third plate 17. Two second rods 16 are fixedly connected between the second plate 15 and the third plate 17. The side walls of the two second rods 16 are all slidably connected with the side wall of the oil storage tank 13.

[0026] After the energy storage battery bodies 10 are respectively placed between the two installation plates 5 in the four installation round holes 2, at this time, adjust the electric push rod 18 to contract, which drives the third plate 17 to move. The third plate 17 drives the second plate 15 to move through the plurality of second rods 16, extruding the hydraulic oil in the oil storage tank 13. At this time, the hydraulic oil in the oil storage tank 13 will respectively enter the eight strip-shaped cavities 6 through the four L-shaped pipes 14, the four rotary joints 11 and the four U-shaped pipes 12, extruding the eight first plates 7 located in the eight strip-shaped cavities 6. Furthermore, the eight first plates 7 drive the eight clamping plates 9 to move closer to the energy storage battery bodies 10, clamping the four energy storage battery bodies 10. It can synchronously clamp the four energy storage battery bodies 10, with simple operation, avoiding the relatively cumbersome operation of driving the clamping plate 9 to move and clamp through screws in the prior art.

[0027] At the same time, by installing the energy storage battery bodies 10 in the four installation round holes 2, the gap between the adjacent energy storage battery bodies 10 is relatively large, which is beneficial to the heat dissipation of the energy storage battery bodies 10, and there is no phenomenon that the adjacent energy storage battery bodies 10 are damaged due to the applied pressure.

[0028] When the cooling fan 20 is started, the wind can be moved from left to right (eg Figure 1 As shown), the energy storage battery body 10 in the four mounting circular holes 2 is heat-dissipated.

[0029] Four motors 21 corresponding to the four gear rings 4 are fixedly connected to the side wall of the box body 1. The movable ends of the four motors 21 are respectively located in the four annular grooves 3. The movable ends of the four motors 21 are fixedly connected to gears 22, which are engaged with the gear rings 4 close to them.

[0030] The four mounting holes 2 are each fixed with an arc tube 23 at the inner top away from the fixing frame 19 . The inner bottom of the four arc tubes 23 is provided with a plurality of through holes 24 . The inner top of the four arc tubes 23 is each fixed with an air intake pipe 25 , which is connected to an external cooling air pump.

[0031] Temperature sensors 26 are installed on the inner walls of the four mounting holes 2 near the fixed frame 19. The temperature sensors 26 are electrically connected to their corresponding motors 21 through an external control mechanism. Solenoid valves 27 are installed in the four air intake pipes 25. The temperature sensors 26 are electrically connected to their corresponding solenoid valves 27 through an external control mechanism.

[0032] The temperature sensor 26 can sense the temperature inside the mounting circular hole 2. When the energy storage battery body 10 is continuously dissipated with heat, the temperature sensed by the temperature sensor 26 is moderate. When the temperature of the energy storage battery body 10 rises due to loss of control or other reasons, the temperature sensor 26 can sense the temperature change, and then the solenoid valve 27 corresponding to the temperature sensor 26 is energized and opened. At this time, the external cold air will flow out through the air intake pipe 25 and the arc tube 23 corresponding to the solenoid valve 27 through the multiple through holes 24, pumping cold air into the mounting circular hole 2 at this location, accelerating the cooling process of the energy storage battery body 10 at this location, and at this time, the motor 21 rotates, driving the gear ring 4 to rotate through the gear 22, driving the energy storage battery body 10 to rotate, and constantly changing the surface of the energy storage battery body 10, thereby increasing the heat dissipation effect on its surface.

[0033] In the present invention, first, the energy storage battery body 10 is placed between the two mounting plates 5 in the four mounting circular holes 2, and then the electric push rod 18 is adjusted to contract, driving the third plate 17 to move. The third plate 17 drives the second plate 15 to move through the multiple second rods 16, squeezing the hydraulic oil in the oil storage tank 13. At this time, the hydraulic oil in the oil storage tank 13 will enter the eight strip cavities 6 through the four L-shaped tubes 14, the four rotary joints 11 and the four U-shaped tubes 12, respectively, and squeeze the eight first plates 7 located in the eight strip cavities 6. Then, the eight first plates 7 drive the eight clamping plates 9 to approach the energy storage battery body 10 through the multiple first rods 8, clamping the four energy storage battery bodies 10, so that the four energy storage battery bodies 10 can be clamped synchronously. At the same time, by installing the energy storage battery bodies 10 in the four installation circular holes 2, the gaps between adjacent energy storage battery bodies 10 are larger, which is beneficial to the heat dissipation of the energy storage battery bodies 10, and there is no pressure applied to the adjacent energy storage battery bodies 10, which causes damage to the energy storage battery bodies 10; Then start the cooling fan 20, and the wind can be moved from left to right (such as Figure 1 As shown), heat dissipation treatment is performed on the energy storage battery body 10 in the four mounting circular holes 2; The temperature sensor 26 can sense the temperature inside the mounting circular hole 2. When the energy storage battery body 10 is continuously dissipated with heat, the temperature sensed by the temperature sensor 26 is moderate. When the temperature of the energy storage battery body 10 rises due to loss of control or other reasons, the temperature sensor 26 can sense the temperature change, and then the solenoid valve 27 corresponding to the temperature sensor 26 is energized and opened. At this time, the external cold air will flow out through the air intake pipe 25 and the arc tube 23 corresponding to the solenoid valve 27 through the multiple through holes 24, pumping cold air into the mounting circular hole 2 at this location, accelerating the cooling process of the energy storage battery body 10 at this location, and at this time, the motor 21 rotates, driving the gear ring 4 to rotate through the gear 22, driving the energy storage battery body 10 to rotate, and constantly changing the surface of the energy storage battery body 10, thereby increasing the heat dissipation effect on its surface.

[0034] The above-mentioned embodiments only express a certain implementation method of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
