[0027] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0028] 1. An inner cavity flexible transmission protection mechanism is provided. Through the mutual cooperation between the various components inside the inner cavity flexible transmission protection mechanism, the protection process during the use of the energy storage device is optimized. The structural design of the internal connection between the sealing rubber sac, the narrow extrusion liquid sac and the wide extrusion liquid sac allows the heat transfer oil inside each component to flow and exchange with each other. The low-friction structural design of the counterweight slider and the sliding vertical block is utilized to adjust the local pressure inside each narrow extrusion liquid sac and the wide extrusion liquid sac by the sliding of the counterweight slider and the sliding vertical block before a sliding collision occurs. The reaction force generated by the battery body squeezing the narrow liquid sac and the wide extrusion liquid sac in the sliding direction is used to reversely squeeze the battery body, thereby effectively preventing the battery body from colliding with the inner isolation protection box, preventing the battery body from being damaged by collision during transportation, and further improving the safety of the energy storage device.

[0029] At the same time, when the internal isolation protection box and the battery body are subjected to external continuous short-range vibration and impact, the narrow and wide liquid sacs can be squeezed in the opposite direction through the sliding of the battery body. The reverse flow of the heat transfer oil inside the narrow and wide liquid sacs drives the counterweight slider and the sliding vertical block to slide. The sliding of the sliding vertical block flexibly transfers and consumes the kinetic energy of the battery body during the impact process, thereby reducing the impact force of the battery body, preventing fatigue damage to the battery body during the alternating collision process, and extending the service life of the energy storage device.

[0030] In addition, during the sliding of the counterweight slider, the effective liquid storage space inside the sealed rubber bag will be adjusted through the connecting belt and the compressed air bag. By reducing the pressure of the heat transfer oil inside the sealed rubber bag away from the sliding direction of the counterweight slider, the internal isolation protection box as a whole will be tilted in the opposite direction of the sliding direction. By changing the overall center of gravity of the internal isolation protection box, the internal isolation protection box will generate an additional upward component force during the sliding process, thereby increasing the sliding resistance of the internal isolation protection box and further improving the overall stability of the energy storage device. The temperature on both sides of the counterweight slider is monitored in real time through a temperature sensor, thereby effectively preventing the battery body from local overheating during use, further expanding the function of the energy storage device and improving the convenience of using the energy storage device.

[0031] 2. An equidistant limiting cooling mechanism is provided. Through the mutual cooperation between the various components within the equidistant limiting cooling mechanism, the installation and heat dissipation process within the energy storage device is optimized. Through the mutual cooperation between the supporting flat box, the air guide vertical box, the limiting arc rod and the installation cross bar, the internal isolation protection box and its internal components can be quickly placed inside the installation main box and fixed, thereby effectively improving the installation convenience of the energy storage device. The internal isolation protection boxes are spliced and limited by the connecting side ears, so that the internal isolation protection boxes can maintain appropriate spacing after installation, thereby allowing the heat generated during the operation of the battery body to be evenly dissipated outward, thereby effectively improving the convenience of use of the energy storage device.

[0032] At the same time, when auxiliary heat dissipation of the internal isolation protection box and its internal components is required, the circulating fan drives the air flow inside the air guide flat box, the supporting flat box and the air guide vertical box to circulate continuously, and during the air circulation process, the dust impurities in the circulating air flow are filtered and intercepted by the collection sliding box and the filter net, effectively preventing the dust in the circulating air flow from contaminating the components inside the installation main box, and effectively improving the heat dissipation efficiency inside the installation main box, so that the energy storage equipment can be maintained within the appropriate temperature range even after long-term use, further improving the stability of the energy storage equipment during use.

[0033] In summary, the transportation and use process of the energy storage equipment is optimized through the mutual cooperation between the internal components of the inner cavity flexible transmission protection mechanism and the equidistant limiting cooling mechanism. The internal isolation protection box and its internal components are flexibly buffered and limited through the mutual cooperation between the internal components. This effectively prevents the battery body from being damaged due to collision during transportation and collision. At the same time, during the use of the energy storage equipment, the internal components of the main box can be continuously cooled, thereby ensuring that the internal temperature of the main box can be maintained within an appropriate range for a long time during use, thereby effectively improving the service life of the energy storage equipment.

A protective top plate 516 is embedded in the middle of the top of the installation main box 1. Connecting side ears 517 are rotatably installed on both sides of the interior of the installation main box 1 and on both sides of the internal isolation protection box 2. The two adjacent connecting side ears 517 are staggered and connected to each other, and the connecting side ears 51 A fixing bolt is installed through the middle of 7. Through the mutual cooperation between the components inside the equidistant limiting cooling mechanism 5, the installation and heat dissipation process inside the energy storage device is optimized. Through the mutual cooperation between the supporting flat box 502, the wind guide vertical box 504, the limiting arc rod 505 and the installation cross bar 507, the internal isolation protection box 2 and the components inside it can be quickly placed inside the installation main box 1 and fixed, thereby effectively improving the installation convenience of the energy storage device. The internal isolation protection boxes 2 are spliced and limited by the connecting side ears 517, so that the internal isolation protection boxes 2 can maintain a suitable spacing after installation, so that the heat generated during the operation of the battery body 3 can be evenly diffused outward, thereby effectively improving the use convenience of the energy storage device.

[0068] At the same time, when auxiliary heat dissipation of the internal isolation protection box 2 and its internal components is required, the circulating fan 509 drives the air flow inside the air guide flat box 508, the support flat box 502 and the air guide vertical box 504 to circulate continuously, and during the air flow circulation, the collecting sliding box 511 and the filter net 512 are used to filter and intercept the dust impurities in the circulating air flow, effectively preventing the dust in the circulating air flow from polluting the internal components of the main box 1, and effectively improving the heat dissipation efficiency inside the main box 1, so that the energy storage equipment can be maintained within the appropriate temperature range even after long-term use, further improving the stability of the energy storage equipment during use.

[0069] Working principle and use process of the present invention: In actual application of the present invention, when the energy storage device is in use, it is necessary to first transport multiple battery main bodies 3 through the internal isolation protection box 2 to a suitable location, and then assemble the battery main bodies 3 inside the installation main box 1 to ensure the normal operation of the energy storage device. During the transportation of the battery main bodies 3 through the internal isolation protection box 2, the battery main bodies 3 need to be protected;

[0070] When the internal isolation protection box 2 and the battery body 3 are transported on the transport equipment, a sudden longitudinal brake occurs. Since the friction between the anti-skid bottom plate 403 and the placement plane is greater than the friction between the counterweight slider 410 and the guide inner frame 409, the counterweight slider 410 inside the internal isolation protection box 2 will slide first before the internal isolation protection box 2 and the battery body 3 slip. The sliding of the counterweight slider 410 squeezes the heat transfer oil at one end of the guide inner frame 409, so that the heat transfer oil at one end of the guide inner frame 409 can be The heat transfer oil diffuses outward through the liquid guide holes at the end of the guide inner frame 409 and the holes on the side of the support base 417. After passing through the support base 417 and entering the liquid guide hard flat box 415, the heat transfer oil inside the liquid guide hard flat box 415 can be guided into the squeezed narrow liquid capsule 419 at the corresponding end through a conduit, causing the squeezed narrow liquid capsule 419 to expand. The expansion of the squeezed narrow liquid capsule 419 then flexibly limits the end of the battery body 3 to prevent the battery body 3 from colliding with the interior of the internal isolation protection box 2 during transportation.

[0071] When an emergency lateral brake occurs during the transportation of the internal isolation protection box 2 and the battery body 3, the sliding vertical block 418 inside the liquid-conducting hard flat box 415 will slide laterally along the top of the supporting base 417, and during the sliding process of the sliding vertical block 418, part of the heat-conducting oil inside the liquid-conducting hard flat box 415 will be introduced into the interior of the transfer curved box 420 through the conduit, and then the heat-conducting oil inside the transfer curved box 420 will be introduced into the interior of the extrusion wide liquid capsule 422 through the connecting small tube 421. After the extrusion wide liquid capsule 422 expands, it fills the gap on the side of the battery body 3, and the side of the battery body 3 is limited by the protective side rubber plate 423;

[0072] When the wide extrusion bladder 422 is squeezed by the sliding battery body 3, part of the heat transfer oil inside the wide extrusion bladder 422 will flow back into the liquid-conducting hard flat box 415, and the high-pressure heat transfer oil on one side of the liquid-conducting hard flat box 415 will push the sliding vertical block 418 to reset in the opposite direction, and transfer and consume the kinetic energy of the battery body 3 during the sliding process of the sliding vertical block 418;

[0073] In addition, during the sliding of the counterweight slider 410, the limit vertical plate 411 can be used to stretch and compress the return spring 412 to ensure that the counterweight slider 410 can automatically return to its original position after sliding. When the connecting belt 428 is pulled by the sliding of the counterweight slider 410, the compression air bag 429 is compressed as the two connecting belts 428 are tightened, thereby increasing the internal liquid storage space of the counterweight slider 410 at the end away from the inner guide frame 409. As a significant pressure difference occurs on both sides of the inner support bottom frame 405, the internal isolation protection box 2 is tilted as a whole toward the low-pressure side of the sealing rubber bag 402, so that the internal isolation protection box 2 and the battery body 3 generate an inclined upward component force through inertia during a sudden braking collision, further reducing the intensity of the end face collision.

[0074] When assembling the internal isolation protection box 2 and the battery body 3, the top of the battery body 3 is limited by the mutual cooperation between the top frame 424 and the protective cover 425, and the gap between the top surface of the battery body 3 and the bottom surface of the protective cover 425 is filled by the telescopic sealing sleeve 426 and the pressing rubber plate 427 to prevent external dust from entering the inner cavity of the internal isolation protection box 2 and polluting the outside of the battery body 3. In the process of placing the battery body 3 into the internal isolation protection box 2, the supporting round box 407 is pushed upward by the pressing spring 408, so that the overall cavity inside the sealing rubber bag 402 becomes larger, thereby causing the narrow liquid bag 419 and the wide liquid bag 422 to shrink toward the outside of the internal isolation protection box 2, making it easier for the battery body 3 to be placed inside the internal isolation protection box 2.

[0075] At the same time, during the use of the energy storage device, the bottom of the battery body 3 is supported by the supporting bottom frame 405, and the heat generated during the operation of the battery body 3 is introduced into the sealed rubber bag 402 through the heat-conducting silicone plate 406 to heat the heat-conducting oil. Since the cavities at both ends of the sealed rubber bag 402 are separated by the counterweight slider 410, the heat exchange rate at both ends of the sealed rubber bag 402 is slow. When uneven heating occurs inside the battery body 3 due to a fault, the heat-conducting oil at both ends of the counterweight slider 410 will have uneven temperature. Then, the temperature at both ends of the counterweight slider 410 is detected by the temperature sensor 414 inside the central mounting tube 413. When the temperature difference at both ends of the counterweight slider 410 is too large, the fault of the battery body 3 can be remotely detected, so that problems inside the energy storage device can be discovered in a timely manner, further improving the convenience of using the energy storage device.

[0076] During the assembly and heat dissipation process of the energy storage device, the back of the internal isolation and protection box 2 is limited by the limiting arc rod 505, and then the end face of the internal isolation and protection box 2 is limited by the mutual splicing between the connecting side ears 517. Finally, the front face of the internal isolation and protection box 2 is limited by the installation block 506 and the installation cross bar 507, thereby achieving the installation and fixation of the internal isolation and protection box 2 and the battery body 3.

[0077] When it is necessary to continuously dissipate heat inside the energy storage device, the air flow inside the air guide flat box 508 is continuously sucked by the circulating fan 509, and then the air flow inside the supporting flat box 502 and the air guide vertical box 504 is continuously sucked, and then the hot air flow inside the installation main box 1 is continuously sucked through the air guide vertical box 504, and the external air flow is introduced into the installation main box 1 through the air inlet side net 515, and then the hot air flow is introduced into the installation side box 501 through the supporting flat box 502 and the air guide vertical box 504, and then the hot air flow is guided by the installation side box 501 to flow continuously from top to bottom, and in the process of the hot air flow passing through the collection slide box 511, the impurities and dust in the hot air flow are filtered and intercepted by the filter mesh 512, and then the downward-flowing hot air flow is continuously dissipated through the heat dissipation side groove 513, and then the filtered hot air flow is discharged from the installation side box 501 through the discharge bottom net 514, thereby achieving continuous heat dissipation inside the energy storage device.

[0078] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
