[0027] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] Please refer to Figure 1-6 , the present invention provides a technical solution: A movable energy storage device of the present invention includes an energy storage box 1. A plurality of battery packs 2 are arranged inside the energy storage box 1. A cooling mechanism 3 is arranged above the battery packs 2. The cooling mechanism 3 is used to cool the battery packs 2. Universal wheels 4 are arranged below the energy storage box 1. A bottom plate 5 is arranged below the battery packs 2. A first limiting component 6 and a second limiting component 7 are arranged below the bottom plate 5. Both the first limiting component 6 and the second limiting component 7 are used to limit the energy storage box 1.

[0029] In the technical solution of the present invention, by providing universal wheels 4 under the energy storage box 1, extremely high mobility is provided, enabling the energy storage device to move easily in different environments, including flat ground, slopes and other various sites, allowing the device to turn and move conveniently in a limited space. By setting the first limiting component 6 and the second limiting component 7, it is ensured that the energy storage box 1 can be stably parked during movement and accidental sliding is avoided, effectively fixing the position of the energy storage box and preventing system instability caused by movement during battery charging and discharging. Through the cooling mechanism 3, cooling can be effectively provided for multiple battery packs 2. A large amount of heat is generated during the charging and discharging process of the battery, and the presence of the cooling mechanism can dissipate heat in a timely manner, ensuring that the battery operates within the optimal temperature range, thereby extending the service life of the battery and improving the safety of the system.

[0030] As Figure 2 and Figure 3 shown, the first limiting component 6 includes a first electric lifting rod 61. The upper part of the first electric lifting rod 61 is connected to the bottom plate 5, and the lower part of the first electric lifting rod 61 is connected to a limiting base 62. A cushion plate 63 is arranged at the bottom of the limiting base 62. The second limiting component 7 includes a second electric lifting rod 71. The upper part of the second electric lifting rod 71 is connected to the bottom plate 5, and the lower part of the second electric lifting rod 71 is connected to a mounting plate 72. A limiting insertion rod 73 is connected to the bottom of the mounting plate 72. Through the control of the first electric lifting rod 61, the limiting base 62 can accurately descend and contact the ground, thereby providing stable support. For a flat ground, the contact surface provided by the limiting base 62 can ensure the fixation of the device, preventing unnecessary displacement of the device. The cushion plate 63 under the limiting base 62 helps to evenly distribute the pressure, increasing the stability of the contact with the ground and avoiding uneven load on the ground, further enhancing the fixation effect. By driving the limiting insertion rod 73 to descend through the second electric lifting rod 71 and inserting it into the uneven ground, the fixation of the device is achieved. For uneven ground, the limiting insertion rod 73 can effectively provide stable support, preventing the device from tilting or becoming unstable due to the uneven ground. Through the electric lifting system, the user can quickly insert the limiting insertion rod 73 into the ground without manual operation, ensuring that the device can remain stable under various ground conditions. This greatly improves work efficiency and reduces the need for manual intervention. The first limiting component and the second limiting component work together. Through the coordinated work of the limiting base and the limiting insertion rod, it is ensured that the device can be firmly fixed on different grounds. The stability of the device is enhanced through multiple limiting designs, especially on complex or uneven grounds, avoiding accidental situations caused by the instability of the equipment.

[0031] As Figure 4 and Figure 5As shown, the battery pack 2 includes a box body 201. Inside the box body 201, multiple battery cell modules 202 are arranged. A composite detector 205 is arranged inside the box body 201. A heat conduction plate 203 is arranged between adjacent battery cell modules 202. A cooling cavity 204 is formed inside the box body 201. By arranging the heat conduction plate 203 between adjacent battery cell modules 202, it helps to effectively conduct and disperse the heat generated between the battery modules, can prevent a single battery cell module from overheating, improve the temperature control performance of the entire battery pack, extend the battery life, and the setting of the cooling cavity 204 enhances the efficiency of the cooling system. Filling the cooling cavity with a coolant can effectively reduce the working temperature of the battery pack and avoid the decline of battery performance or safety hazards caused by overheating.

[0032] Among them, the composite detector 205 can monitor the state of the battery pack in real time, including key parameters such as temperature, voltage, and current. Through this intelligent detection, the system can detect in real time whether the battery pack is in a safe working state and can give an early warning or take protection measures in time (such as cutting off the power supply, starting the cooling system, etc.), effectively preventing the occurrence of safety accidents.

[0033] Such as Figure 2 And Figure 4As shown in the figure, the temperature reduction mechanism 3 includes a cooling tank 31 and a diversion pipe 32. There is coolant inside the cooling tank 31, a refrigeration box 33 is arranged outside the cooling tank 31, a first pump box 34 is arranged on one side of the cooling tank 31, the first pump box 34 is connected to the battery pack 2 through a connecting pipe 35, a return pipe 36 is arranged on the cooling tank 31, and the return pipe 36 is connected to the battery pack 2; The cooling tank 31 is filled with coolant inside, which can absorb the excess heat generated by the battery pack 2 and ensure that the battery operating temperature is within a safe range. The coolant, as a heat conduction medium, can quickly and effectively take away heat and prevent the battery pack from overheating. A refrigeration box 33 is arranged outside the cooling tank 31, which can provide an additional cooling effect through active cooling means. The refrigeration box can reduce the temperature of the coolant in real time, thereby improving the heat exchange efficiency of the overall system and ensuring that the battery pack is always within the optimal temperature range. The first pump box 34 is connected to the battery pack 2 through the connecting pipe 35, and can promote the liquid flow by pumping the coolant. Through continuous coolant circulation, heat can be effectively transferred from the battery pack 2 to the cooling tank 31 and then further cooled by the refrigeration box 33. The flow of the coolant ensures a continuous cooling effect and avoids the occurrence of local overheating. The return pipe 36 guides the cooled liquid back to the battery pack 2 to form a closed cooling circulation system. After circulating, the coolant can efficiently take away the heat generated by the battery pack and ensure the cooling efficiency. Through the effective control of the coolant and the cooling system, the temperature reduction mechanism can adjust the temperature in real time according to the working state of the battery pack, avoid the decline of battery performance caused by too high temperature, and even prevent thermal runaway. The efficient cooling system significantly improves the stability and safety of the energy storage device. Through continuous circulation of the coolant, heat will not accumulate inside or around the battery pack, thereby reducing potential safety hazards such as equipment damage and fire caused by too high temperature.

[0034] As Figure 1 and Figure 2 shown in the figure, a spray component 8 is arranged on one side of the temperature reduction mechanism 3. The battery pack 2 is connected to a heat preservation board 10 through a reinforcement board 9. The spray component 8 includes a second pump box 81. The second pump box 81 is connected to a spray pipe 82. A plurality of spray nozzles 83 are arranged on the spray pipe 82. Each spray nozzle 83 is connected to the battery pack 2, and a first electric control valve 84 is arranged on each spray nozzle 83; By operating the second pump box 81, the cooling water inside the cooling tank 31 can be introduced into the spray pipe 82, and the coolant can be evenly sprayed inside the battery pack 2.

[0035] Specifically, the composite detector 205 can monitor in real time whether the temperature inside the battery pack exceeds the set threshold. The composite detector 8 will transmit the signal to the control box 11. When the control box 11 detects a dangerous situation, the control box 11 will control the second pump box 81 to work, and inject the cooling water inside the cooling box 31 into the spray pipe 82 and pour it into the specified battery pack 2 for fire extinguishing. Fire extinguishing the internal battery pack 2 can effectively perform the fire extinguishing operation and enhance the reliability and safety of the device.

[0036] Among them, a liquid spray pipe 14 is connected between adjacent battery packs 2, and a second solenoid valve 15 is arranged on the liquid spray pipe 14; the flow of the liquid spray pipe 14 can be controlled through the second solenoid valve 15, and the cooling water in the cooling cavity 204 is introduced into the battery pack 2 to accelerate the fire extinguishing efficiency.

[0037] As Figure 1 and Figure 6 As shown, the heat insulation board 10 includes a silica board 1001 and an asbestos board 1002. The silica board 1001 is connected to the inner wall of the energy storage box 1. One side of the silica board 1001 is connected to the asbestos board 1002, and the asbestos board 1002 is attached to the battery pack 2; due to the excellent high-temperature resistance of silica, it can effectively block the external heat conduction into the energy storage system. As the first layer connected to the inner wall of the energy storage box 1, the silica board 1001 can avoid the interference of the external environmental temperature and maintain stable structural performance in a high-temperature environment without deformation due to thermal expansion and contraction. Asbestos has high heat resistance and good heat insulation ability, which can effectively reduce the influence of the external high temperature on the battery pack 2. The design of attaching the asbestos board 1002 to the battery pack 2 can ensure that the battery pack always remains within the ideal temperature range, effectively avoiding the decline of battery performance or safety problems caused by excessive temperature. The dual heat insulation effect of silica and asbestos can greatly reduce the heat transfer. Especially when the energy storage device is operating at high load, the battery pack may generate a large amount of heat. The design of the heat insulation board can effectively control the heat propagation inside the energy storage box, avoid heat leakage to the outside or other components being affected, and reduce the risk of failures caused by overheating.

[0038] Among them, a control box 11 is arranged inside the energy storage box 1, and the outside of the energy storage box 1 is connected to the sealing door 13 through a sealing gasket 12.

[0039] Working principle: The universal wheels are equipped under the energy storage box, providing extremely high mobility, enabling the energy storage device to move easily in different environments, including flat ground, slopes and other various sites, allowing the device to turn and move conveniently in a limited space. By setting the first limiting component and the second limiting component, it is ensured that the energy storage box can be stably parked during movement and avoid accidental sliding, effectively fixing the position of the energy storage box and preventing system instability caused by movement during battery charging and discharging. Through the cooling mechanism, it can effectively provide cooling for multiple battery packs. A large amount of heat is generated during the charging and discharging process of the battery, and the presence of the cooling mechanism can dissipate heat in a timely manner, ensuring that the battery operates within the optimal temperature range, thereby extending the service life of the battery and improving the safety of the system.
