For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1 like Figures 1 to 10 As shown, the portable energy storage device includes an outer box frame 1, such as Figure 2 As shown, the energy storage device body 2 is fixedly installed inside the outer box frame 1.

[0027] like Figure 8 As shown, the left and right sides of the outer box frame 1 are both rotatably mounted with steering shafts 3, and the steering shafts 3 are both fixedly sleeved with side wing display panels 4, as shown in FIG. Figure 2 As shown, the energy storage device body 2 is located inside the two side wing panels 4 .

[0028] In this embodiment, a U-shaped baffle can be provided inside the outer box frame 1 to form a first window, which is provided on one side of the side wing display panel 4. When the side wing display panel 4 is closed, the first window on one side of the side wing display panel 4 is covered to improve the sealing between the side wing display panel 4 and the outer box frame 1. Figure 5 As shown, four limit telescopic tubes 5 are fixedly installed inside the outer box frame 1. The bottom end of the limit telescopic tube 5 is fixed, and the top end can be raised and lowered. The four limit telescopic tubes 5 are evenly distributed around the energy storage device body 2, as shown in FIG. Figure 2 As shown, a top plate 6 is fixedly mounted on the top ends of the four position-limiting telescopic tubes 5 .

[0029] like Figure 6 As shown, the driving mechanism includes a transmission motor 9, a transmission gear 10 and a driven gear 12. The transmission box 8 is fixedly installed inside the outer box frame 1, and the transmission motor 9 is fixedly installed inside the transmission box 8. The output shaft of the transmission motor 9 is fixedly sleeved with the transmission gear 10. A transmission groove 101 is opened on one side of the outer box frame 1. One end of one steering shaft 3 is located inside the transmission groove 101 and is fixedly sleeved with the driven gear 12. The driven gear 12 is meshed with the transmission gear 10. Figure 2As shown, the side of the side wing display panel 4 facing away from the energy storage device body 2 is rotatably mounted with a linkage bracket 7, and the top ends of the two linkage brackets 7 are rotatably mounted on the two sides of the top plate 6. It should be noted that in this embodiment, the outer edge width (the length value in the left-right direction) of the top plate 6 is smaller than the outer edge spacing of the two side wing display panels 4, so that when the side wing display panels 4 are combined on both sides of the outer box frame 1, the linkage bracket 7 is not in a vertical state, and the linkage brackets 7 on both sides have a certain inclination angle, which is tilted from top to bottom toward the outside to prevent the top plate 6 from failing to drive the side wing display panel 4 on the other side to flip outward.

[0030] When the portable mobile energy storage device is in use, the transmission motor 9 inside the transmission box 8 drives the transmission gear 10 to rotate, and then drives the steering shaft 3 to rotate through the meshing driven gear 12, so that the side wing display panel 4 on one side is flipped outward and opened, and then the side wing display panel 4 on this side drives the top plate 6 to move upward along the telescopic direction of the limiting telescopic tube 5 through the linkage bracket 7, so that the top plate 6 is lifted, and the top plate 6 then drives the side wing display panel 4 on the other side to flip outward through another linkage bracket 7, so that the top plate 6 and the linkage brackets 7 on both sides are changed from a closed state to an expanded state, which is convenient for displaying the energy storage device body 2 for charging, and at the same time improves the natural heat dissipation effect of the energy storage device body 2 during operation.

[0031] A fire extinguishing assembly is arranged inside the outer box frame 1 , and the fire extinguishing assembly is used to spray dry powder to the energy storage device body 2 and the surrounding side of the energy storage device body 2 to extinguish the fire when the energy storage device body 2 fails and catches fire.

[0032] like Figure 4 As shown, the fire extinguishing assembly includes two spraying devices 13 fixedly installed inside the outer box frame 1, and the two spraying devices 13 are respectively located on both sides of the energy storage device body 2, such as Figure 7 As shown, tank racks 14 are fixedly installed on both sides of the bottom of the spraying device 13, and high-pressure dry powder tanks 15 are placed on the tank racks 14. The gas delivery end of the high-pressure dry powder tank 15 is connected to the gas inlet end of the spraying device 13. Two main control three-way valves 16 are fixedly installed on the top of the spraying device 13. The two main control three-way valves 16 are respectively connected to the two high-pressure dry powder tanks 15, and one end of the main control three-way valve 16 is fixedly installed with a first fire extinguishing nozzle 17. Figure 4 As shown, the first fire extinguishing nozzles 17 are all directed toward the energy storage device body 2 in the front-to-back direction. Figure 7As shown, the other end of the main control three-way valve 16 is fixedly installed with a lower air pipe 19, and two fire-extinguishing bottom pipes 20 are fixedly installed on the inner wall of the bottom of the outer box frame 1. The outer box frame 1 is located between the two fire-extinguishing bottom pipes 20, and the two ends of the fire-extinguishing bottom pipe 20 located on the same side (left or right) are respectively fixedly connected to the bottom ends of the front and rear two lower air pipes 19, and a plurality of evenly distributed second fire-extinguishing nozzles 21 are fixedly installed on the top of the fire-extinguishing bottom pipe 20. In this embodiment, the outer box frame 1 is internally provided with temperature sensors, smoke alarms and other fire detection devices for monitoring the energy storage device body 2 and the surrounding conditions so as to timely sense fire accidents; specifically, by arranging a fire-extinguishing component, when the energy storage device body 2 fails and catches fire, the transmission motor 9 will drive the top plate 6 and the side wing display panels 4 on both sides to be merged on the outer box frame 1 in time, The energy storage device body 2 is isolated from the outside world, air circulation is reduced, and the fire source quickly consumes internal oxygen and extinguishes itself or reduces the fire. At the same time, the spraying devices 13 on both sides of the energy storage device body 2 will extract high-pressure dry powder mixed gas from the high-pressure dry powder tank 15, and spray it on a large scale toward both sides of the energy storage device body 2 through the main control three-way valve 16 and the first fire extinguishing nozzle 17, thereby accelerating the progress of fire extinguishing. At the same time, part of the dry powder will be transmitted to the fire extinguishing bottom pipe 20 on both sides of the bottom of the outer box frame 1 through the lower air pipe 19, and sprayed upward through the second fire extinguishing nozzle 21 on the top of the fire extinguishing bottom pipe 20, so that the other two sides of the energy storage device body 2 are covered by the dry powder sprayed from bottom to top, so that the fire point there can be quickly extinguished, thereby cooperating with the spraying of the first fire extinguishing nozzle 17, expanding the coverage of the dry powder, and improving the fire extinguishing range and fire extinguishing effect of the fire extinguishing component.

[0033] The two side wing display panels 4 are provided with pneumatic locking components for locking the side wing display panels 4 and the outer box frame 1 when the energy storage device body 2 fails and catches fire.

[0034] like Figure 8 As shown, the pneumatic locking assembly includes a main airbag 22 fixedly installed inside the side wing display panel 4, side wing folding airbags 23 are fixedly installed on both sides and the bottom of the main airbag 22, the side wing folding airbags 23 are connected to the inside of the main airbag 22, locking slide holes are provided at both ends (in the front and rear directions) and the bottom of the side wing display panel 4, locking slide plates 24 are slidably installed inside the locking slide holes, return spring rods 25 are provided on both sides of the side wing folding airbag 23, the return spring rods 25 are fixedly installed inside the side wing display panel 4, and the locking slide plates 24 located on the same side are fixedly installed on the telescopic ends of the two return spring rods 25 so that the locking slide plates 24 have a tendency to retract.

[0035] like Figure 3 As shown, both sides and the bottom inner wall of the outer box frame 1 are provided with a card slot 102 adapted to the locking slide plate 24. Figure 7As shown, a filter three-way valve 18 is fixedly installed on the lower air pipe 19, and a gas delivery hose 26 is fixedly installed at one end of the filter three-way valve 18. Figure 2 As shown, one end of the two gas hoses 26 located on the same side extends to the interior of the side wing display panel 4 and is connected to the interior of the main airbag 22; specifically, by arranging a pneumatic locking assembly, when the first fire extinguishing nozzle 17 sprays dry powder to both sides of the energy storage device body 2, part of the gas will flow into the gas hose 26 through the filtering three-way valve 18, and then enter the interior of the main airbags 22 on both sides, so that the main airbags 22 and the side folding airbags 23 on the three sides are inflated by the air pressure, and the side folding airbags 23 push the locking slide plate 24 to slide toward the outside of the locking slide hole until one side of the locking slide plate 24 slides out of the locking slide hole and is stuck in the card slot 102 on the outer box frame 1. At this time, the locking slide plate 24 spans the side wing display panel 4 and the outer box frame 1, which not only improves the sealing of the joint between the side wing display panel 4 and the outer box frame 1, but also can lock and stick the side wing display panel 4 and the outer box frame 1, preventing the side wing display panel 4 from being pushed by the high-temperature gas inside and flipping outward, resulting in failure to isolate the fire point.

[0036] like Figure 1 As shown, a bottom box 27 is fixedly installed at the bottom of the outer box frame 1. Fig. 9 As shown, four balancing water tanks 28 are fixedly installed inside the bottom box 27, a cooling water pump 29 is fixedly installed inside the bottom box 27, a water delivery pipe 30 and a water pumping pipe 31 are fixedly installed on the water outlet and water inlet ends of the cooling water pump 29, respectively, a water inlet pipe network 32 and a water outlet pipe network 33 are fixedly installed inside the bottom box 27, the balancing water tank 28 is connected to the water inlet pipe network 32 and the water outlet pipe network 33, and the water inlet pipe network 32 and the water outlet pipe network 33 are connected to the water delivery pipe 30 and the water pumping pipe 31, respectively, as shown in FIG. Figure 4 As shown, a heat sink 34 is fixedly mounted on the bottom inner wall of the outer box frame 1, and the heat sink 34 is located at the bottom of the energy storage device body 2, as shown in FIG. Fig.10 As shown, one end of the water pipe 30 and the water extraction pipe 31 extend to the interior of the heat sink 34 and are fixedly installed with the same cooling pipe network 35; specifically, by arranging the cooling water pump 29, when the energy storage device body 2 is in operation, the cooling water pump 29 at the bottom of the outer box frame 1 can extract cooling water from each balancing water tank 28 through the control valve 36, and transport it to the cooling pipe network 35 through the water pipe 30, so that the cooling water flows in the heat sink 34 and the cooling pipe network 35, and then the energy storage device body 2 is water-cooled from the bottom, and the natural heat dissipation after the side wing expansion board 4 and the top board 6 are unfolded, so that the energy storage device body 2 obtains a good heat dissipation effect, thereby keeping the working condition of the energy storage device body 2 stable.

[0037] like Figure 1 , Figure 2As shown, self-locking retractable wheels 42 are fixedly installed around the bottom of the bottom box 27. In the present embodiment, the self-locking retractable wheels 42 can adopt universal self-locking wheels with threaded retractable rods commonly seen on the market, so as to facilitate the adjustment of height and fixed position; specifically, by setting the self-locking retractable wheels 42, the self-locking retractable wheels 42 facilitate the movement of the entire equipment. When the equipment stops moving, the height of each self-locking retractable wheel 42 can be adjusted so that the outer box frame 1 is in a balanced state as a whole without shaking left and right, thereby maintaining the stability of the external working conditions during the operation of the energy storage device body 2.

[0038] like Fig. 9 As shown, the positions of the four balancing water tanks 28 correspond to the positions of the four self-locking telescopic wheels 42 respectively, and a plurality of control valves 36 are provided on the water inlet network 32 and the water outlet network 33. In the present embodiment, a gyroscope is provided inside the outer box frame 1 to provide reference data for the weight adjustment of the balancing water tanks 28; specifically, by providing the control valves 36, when water cooling is not required, the cooling water pump 29 can cooperate with the coordinated control of the various control valves 36 to extract cooling water from each balancing water tank 28 and re-transport it to different balancing water tanks 28, thereby changing the water storage volume inside each balancing water tank 28, balancing the weight of the bottom of the outer box frame 1, and coordinating with the height adjustment of the self-locking telescopic wheels 42 to improve the balance of the position of the outer box frame 1.

[0039] like Figure 4 , Figure 5 As shown, a same hollow plate 37 is fixedly installed between two limiting telescopic tubes 5 located on the same side, and the two hollow plates 37 are respectively located on both sides of the energy storage device body 2, and the two first fire extinguishing nozzles 17 located on the same side both penetrate the hollow plates 37 and extend to one side of the energy storage device body 2; specifically, by setting the hollow plates 37, the hollow plates 37 located on both sides of the energy storage device body 2 can separate the energy storage device body 2 from the eruption device 13. When the energy storage device body 2 fails and catches fire, the hollow plates 37 and the hollow structures of the limiting telescopic tubes 5 on both sides can play a role of heat insulation, and a fire barrier is set between the energy storage device body 2 and the eruption device 13 to reduce the influence of the high temperature and high heat gas inside the outer box frame 1 on the normal operation of the eruption device 13, thereby extending the time for the eruption device 13 to spray dry powder for fire extinguishing.

[0040] like Figure 4 , Figure 5 As shown, two dustproof side mesh panels 38 are fixedly installed inside the outer box frame 1. The two dustproof side mesh panels 38 are distributed on both sides of the energy storage device body 2 and correspond to the positions of the two side wing display panels 4 respectively to cover the first window. An interactive hole 3801 is opened on one of the dustproof side mesh panels 38. In this embodiment, the position of the interactive hole 3801 corresponds to the position of the operation panel of the energy storage device body 2. Figure 2As shown, the same dustproof mesh plate 39 is fixedly installed between the two dustproof side mesh plates 38, and the dustproof mesh plate 39 is located at the top of the energy storage device body 2. The dustproof mesh plate 39 is fixedly installed between the two hollow plates 37 to cover the second window. Specifically, by setting the dustproof side mesh plates 38 and the dustproof mesh plate 39, after the top plate 6 and the side wing display plate 4 are unfolded, the dustproof side mesh plates 38 and the top dustproof mesh plate 39 on both sides can be combined with the hollow plates 37 and the limiting telescopic tube 5 on both sides to store the energy storage device body 2 inside, so that the dustproof side mesh plates 38 and the dustproof mesh plate 39 play a dustproof effect, and prevent dust from entering the interior of the outer box frame 1 through the gap after the side wing display plate 4 and the top plate 6 are unfolded, which affects the normal operation and daily storage of the energy storage device body 2. When in use, the interactive hole 3801 can be used to interact with the panel of the energy storage device body 2.

[0041] like Figure 1 As shown, maintenance doors 40 are rotatably installed on both sides of the outer box frame 1, and the two maintenance doors 40 correspond to the positions of the two spraying devices 13 respectively. A locking handle 41 is provided on the side of the maintenance door 40 away from the spraying device 13. In the present embodiment, a mechanical lock is provided on the locking handle 41; specifically, by providing the maintenance door 40, when the equipment is maintained, the locking handle 41 can be unlocked by a key, and then the locking handle 41 is rotated to open the maintenance door 40, and then the state of the internal spraying device 13 and the air pressure inside the high-pressure dry powder tank 15 can be checked, so that the maintenance of the spraying device 13 and the replacement of the high-pressure dry powder tank 15 can be conveniently realized.

[0042] like Figure 1 As shown, a plurality of one-way gas valves 11 are fixedly installed on the top of the top plate 6; specifically, by setting the one-way gas valves 11, after the energy storage device body 2 catches fire, the side wing expansion panels 4 and the top plate 6 will seal the inside of the outer box frame 1, and the high-temperature gas generated by the combustion of the energy storage device body 2 will surge upward. At the same time, the dry powder gas sprayed from the first fire extinguishing nozzle 17 and the second fire extinguishing nozzle 21 will push the high-temperature gas to surge upward until a large amount of high-temperature gas and air mixture is discharged from the one-way gas valve 11 on the top of the top plate 6, quickly reducing the oxygen content inside the outer box frame 1, and further improving the speed and effect of fire extinguishing.

[0043] In summary: before use: the self-locking retractable wheels 42 are used to facilitate the movement of the entire device. When the device stops moving, the height of each self-locking retractable wheel 42 can be adjusted to make the outer box frame 1 as a whole in a balanced state without shaking left and right, thereby maintaining the stability of the external working conditions during the operation of the energy storage device body 2. When water cooling is not required, the cooling water pump 29 can cooperate with the coordinated control of each control valve 36 to extract cooling water from each balancing water tank 28 and re-transport it to different balancing water tanks 28, change the water storage volume inside each balancing water tank 28, balance the weight of the bottom of the outer box frame 1, and cooperate with the height adjustment of the self-locking retractable wheel 42 to lift the outer box frame 1 to a certain position. In order to ensure the balance of the device, the transmission motor 9 inside the transmission box 8 drives the transmission gear 10 to rotate, and then drives the steering shaft 3 to rotate through the meshing driven gear 12, so that the side wing display panel 4 on one side is flipped outward and opened, and then the side wing display panel 4 on this side drives the top plate 6 to move upward along the telescopic direction of the limiting telescopic tube 5 through the linkage bracket 7, so that the top plate 6 is lifted, and the top plate 6 drives the side wing display panel 4 on the other side to flip outward through another linkage bracket 7, so that the top plate 6 and the linkage brackets 7 on both sides are changed from a closed state to an expanded state, which is convenient for displaying the energy storage device body 2 for charging, and at the same time improves the natural heat dissipation effect of the energy storage device body 2 during work.

[0044] During use: the cooling water pump 29 at the bottom of the outer box frame 1 can extract cooling water from each balancing water tank 28 through the control valve 36, and transport it to the cooling pipe network 35 through the water pipe 30, so that the cooling water flows in the heat sink 34 and the cooling pipe network 35, and then the energy storage device body 2 is water-cooled from the bottom, and the natural heat dissipation after the side wing expansion board 4 and the top board 6 are unfolded, so that the energy storage device body 2 can obtain a good heat dissipation effect, so that the working condition of the energy storage device body 2 remains stable, and then the interaction hole 3801 can be used to interact with the panel of the energy storage device body 2.

[0045] After use: When maintaining the equipment, the locking handle 41 can be unlocked with a key, and then the locking handle 41 can be turned to open the maintenance door 40, and then the state of the internal spraying device 13 and the air pressure inside the high-pressure dry powder tank 15 can be checked, which facilitates the maintenance of the spraying device 13 and the replacement of the high-pressure dry powder tank 15.

[0046] When a fire occurs: When the energy storage device body 2 fails and catches fire, the transmission motor 9 will drive the top plate 6 and the side wing display panels 4 on both sides to merge with the outer box frame 1 in time, so that the energy storage device body 2 is isolated from the outside world, reducing air circulation, so that the fire source quickly consumes internal oxygen and extinguishes itself or reduces the fire. At the same time, the spraying devices 13 on both sides of the energy storage device body 2 will extract high-pressure dry powder mixed gas from the high-pressure dry powder tank 15, and spray it in a large range toward both sides of the energy storage device body 2 through the main control three-way valve 16 and the first fire extinguishing nozzle 17, accelerating the progress of fire extinguishing. At the same time, part of the dry powder will be transmitted to the fire extinguishing bottom pipe 20 on both sides of the bottom of the outer box frame 1 through the lower air pipe 19, and sprayed upward through the second fire extinguishing nozzle 21 at the top of the fire extinguishing bottom pipe 20, so that the other two sides of the energy storage device body 2 are covered by the dry powder sprayed from bottom to top, so that the fire point there can be quickly extinguished. At the same time, part of the gas will flow into the gas supply hose 26 through the filtering three-way valve 18, and then input into the main control three-way valve 16 on both sides. The inside of the airbag 22 causes the main airbag 22 and the side folding airbags 23 on the three sides to swell under the action of air pressure, and the side folding airbags 23 push the locking slide plate 24 to slide toward the outside of the locking slide hole until one side of the locking slide plate 24 slides out of the locking slide hole and is stuck in the slot 102 on the outer box frame 1. At this time, the locking slide plate 24 spans the side wing display panel 4 and the outer box frame 1, which not only improves the sealing of the joint between the side wing display panel 4 and the outer box frame 1, but also can lock and stick the side wing display panel 4 and the outer box frame 1 to prevent the side wing display panel 4 from being pushed by the internal high-temperature gas and flipping outward, resulting in failure to isolate the fire point, and the high-temperature gas generated by the combustion of the energy storage equipment body 2 will surge upward. At the same time, the dry powder gas sprayed from the first fire extinguishing nozzle 17 and the second fire extinguishing nozzle 21 will push the high-temperature gas to surge upward until a large amount of high-temperature gas and air mixture is discharged from the one-way air valve 11 on the top of the top plate 6, quickly reducing the oxygen content inside the outer box frame 1, and further improving the speed and effect of fire extinguishing.

[0047] The beneficial effects of the present invention are as follows: 1. The present invention sets a fire extinguishing assembly so that when the energy storage device body 2 fails and catches fire, the transmission motor 9 will drive the top plate 6 and the side wing display panels 4 on both sides to merge onto the outer box frame 1 in time, so that the energy storage device body 2 is isolated from the outside world, reducing air circulation, so that the fire source quickly consumes internal oxygen and extinguishes itself or reduces the fire. At the same time, the spraying devices 13 on both sides of the energy storage device body 2 will spray dry powder to both sides of the energy storage device body 2 through the first fire extinguishing nozzle 17, so as to accelerate the progress of fire extinguishing; 2. The present invention sets a fire extinguishing bottom pipe 20, so that part of the dry powder is transmitted to the fire extinguishing bottom pipe 20 through the lower air pipe 19, and sprayed upward through the second fire extinguishing nozzle 21 at the top of the fire extinguishing bottom pipe 20, so that the other two sides of the energy storage device body 2 are covered by the dry powder sprayed from bottom to top, so that the fire point there can be quickly extinguished, thereby cooperating with the spraying of the first fire extinguishing nozzle 17, expanding the coverage of the dry powder, and improving the fire extinguishing range and fire extinguishing effect of the fire extinguishing assembly; 3. The present invention provides a pneumatic locking assembly so that when the first fire extinguishing nozzle 17 sprays dry powder to both sides of the energy storage device body 2, part of the gas will be input into the main airbags 22 on both sides, so that the side folding airbags 23 swell and push the locking slide plate 24 toward the sliding hole and into the card slot 102, thereby improving the sealing of the joint between the side wing display panel 4 and the outer box frame 1, and also locking the side wing display panel 4 and the outer box frame 1, so as to prevent the side wing display panel 4 from being pushed and turned over by the high-temperature gas inside, resulting in isolation failure; 4. When the present invention is in use, the transmission motor 9 drives the side wing display panel 4 on one side to flip outward and open, and then drives the top plate 6 to lift up. The top plate 6 then drives the side wing display panel 4 on the other side to flip outward through another linkage bracket 7, so that the top plate 6 and the linkage brackets 7 on both sides are turned from a closed state to an unfolded state, which is convenient for displaying the energy storage device body 2 for charging, and at the same time improves the natural heat dissipation effect of the energy storage device body 2 during operation; 5. The present invention is provided with a cooling water pump 29, so that the cooling water pump 29 can extract cooling water from each balancing water tank 28 through a control valve 36, and transport it to the cooling pipe network 35 through a water pipe 30, so that the cooling water flows in the heat sink 34 and the cooling pipe network 35, and then the energy storage device body 2 is water-cooled from the bottom, and the natural heat dissipation after the side wing expansion board 4 and the top board 6 are unfolded, so that the energy storage device body 2 obtains a good heat dissipation effect, so that the working condition of the energy storage device body 2 remains stable; 6. The present invention provides self-locking retractable wheels 42 so that the height of each self-locking retractable wheel 42 can be adjusted, so that the outer box frame 1 is in a balanced state as a whole without shaking left and right. At the same time, when water cooling is not required, the cooling water pump 29 can cooperate with the coordinated control of each control valve 36 to change the water storage volume inside each balancing water tank 28, balance the weight at the bottom of the outer box frame 1, and cooperate with the height adjustment of the self-locking retractable wheel 42 to maintain the stability of the external working conditions during the operation of the energy storage device body 2; 7. The present invention provides a hollow plate 37 so that the hollow plate 37 can separate the energy storage device body 2 from the eruption device 13. When the energy storage device body 2 fails and catches fire, the hollow plate 37 and the hollow structure of the limiting telescopic tubes 5 on both sides can play a role of heat insulation, and a fire barrier is provided between the energy storage device body 2 and the eruption device 13, reducing the influence of the high temperature and hot gas inside the outer box frame 1 on the normal operation of the eruption device 13, thereby extending the time for the eruption device 13 to spray dry powder to extinguish the fire; 8. The present invention provides dustproof side mesh panels 38 and dustproof upper mesh panels 39, so that after the top plate 6 and the side wing display panels 4 are unfolded, the dustproof side mesh panels 38 on both sides and the top dustproof upper mesh panels 39 can store the energy storage device body 2 inside together with the hollow plates 37 on both sides and the limiting telescopic tube 5, thereby achieving a dustproof effect and preventing dust from entering the interior of the outer box frame 1 through the gaps after the side wing display panels 4 and the top plate 6 are unfolded, thereby affecting the normal operation and daily storage of the energy storage device body 2; 9. The present invention provides a maintenance door 40, so that when the equipment is maintained, the locking handle 41 can be unlocked by a key, and then the locking handle 41 can be turned to open the maintenance door 40, and then the state of the internal spraying device 13 and the air pressure inside the high-pressure dry powder tank 15 can be checked, so that the maintenance of the spraying device 13 and the replacement of the high-pressure dry powder tank 15 can be easily achieved; 10. The present invention provides a one-way gas valve 11 so that after the energy storage device body 2 catches fire, the high-temperature gas generated by the combustion of the energy storage device body 2 will surge upward, and at the same time, the dry powder gas sprayed from the first fire extinguishing nozzle 17 and the second fire extinguishing nozzle 21 will push the high-temperature gas to surge upward until a large amount of high-temperature gas and air mixture is discharged from the one-way gas valve 11 on the top of the top plate 6, quickly reducing the oxygen content inside the outer box frame 1, and further improving the speed and effect of fire extinguishing.

[0048] Example 2 like Fig.11 As shown, the difference from Example 1 is that in this embodiment, a push valve is provided between the filtering three-way valve 18 and the gas hose 26, and the push valve can control the on and off of the gas hose 26. The push valve is fixedly connected to the outer box frame. A passage 51 is provided in the push valve, one end of the passage 51 is connected to the filtering three-way valve 18, and the other end is connected to the gas hose 26. When the passage 51 is connected, the gas in the filtering three-way valve 18 can enter the gas hose 26. A mounting hole 52 connected to the passage 51 and perpendicular to the passage 51 is provided on the side wall of the passage 51, a valve core 53 is slidably connected in the mounting hole 52, a return spring 54 is provided between one end of the valve core 53 and the mounting hole 52, and a pressing rod 55 is provided at the other end of the valve core 53, and the pressing rod 55 vertically penetrates the passage 51. In a natural state, the valve core 53 is located in the passage 51 under the action of the spring, cutting off the passage 51 . Pressing the valve stem can make the valve core 53 enter the mounting hole 52 , so that the passage 51 is open.

[0049] The working principle is as follows: the outer end (trigger end) of the pressing rod 55 is located on the rotation path of the side wing display panel 4. When the side wing display panel 4 is in the unfolded state, the pressing rod 55 is in a free state, and the return spring 54 pushes the valve core 53 to move to the passage 51 to cut off the passage 51. When a fault occurs and a fire occurs, the side wing display panel 4 is first flipped and closed. After being completely closed, the side wing display panel 4 abuts against the pressing rod 55, and pushes the valve core 53 into the mounting hole 52 to make the passage 51 conductive. At this time, the gas enters the airbag and the pneumatic locking assembly is activated, which can prevent the locking slide plate 24 from being misaligned with the card slot 102 when it is pushed out. By setting a pressing valve, the pneumatic locking assembly can be prevented from being started prematurely. Assuming that after premature activation, the extended locking slide plate 24 will abut against the frame of the first window, causing the side wing display panel 4 to be unable to cover the first window, affecting the sealing.

[0050] In other feasible solutions, other linkage structures or electric control methods may be used to achieve that the side wing display panel 4 is first switched to a closed state and then the locking slide plate 24 is extended.

[0051] Example 3 like Fig.12 As shown, the difference from Example 1 is that the energy storage device further includes a first rack 61, a first gear 62, a second gear 63, a second rack 64 and a push rod 65. The first rack 61 is vertically slidably connected to the outer box frame 1, and the top end of the first rack 61 is connected to the top plate 6. Driven by the top plate 6, the first rack 61 can move vertically.

[0052] The first gear 62 and the second gear 63 can be arranged in the energy storage device body 2. The first rack 61 is meshed with the first gear 62. The first gear 62 and the second gear 63 are coaxially connected, and the first gear 62 can drive the second gear 63 to rotate, and the two have the same motion state.

[0053] The second rack 64 is slidably connected to the outer box frame 1, and a part of the second rack 64 is located inside the energy storage device body 2, and one end of the second rack 64 is connected to the push rod 65, the second rack 64 is meshed with the second gear 63, and the second rack 64 moves forward and backward to drive the push rod 65 to move forward and backward.

[0054] The control panel is provided with a socket 66, and the socket 66 has a socket group, which can be three holes or two holes. The socket 66 is provided with a through hole penetrating the front and rear surfaces thereof, and the through hole is located in the center area of ​​the socket group. For example, in a three-hole socket group, the through hole is located in the center of the three holes, and the push rod 65 passes through the through hole, and the push rod 65 is used to push the plug away from the socket 66.

[0055] By setting the gear ratio of the first gear 62 and the second gear 63 , the side wing display panel 4 can be completely closed after the push rod 65 pushes the plug out.

[0056] The working principle is as follows: in the initial state, the top end of the push rod 65 is located inside the through hole and will not interfere with the insertion of the plug. When a fire occurs, the top plate 6 descends, which can drive the first rack 61 to move downward, and the first gear 62, the second gear 63 and the second rack 64 can drive the push rod 65 to move forward, so that the plug on the socket 66 can be pushed out, and then the side wing display panel 4 is completely closed to avoid the side wing display panel 4 from clamping the wire connected to the plug when closing, resulting in the side wing display panel 4 being unable to be completely closed.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
