[0041] The storage battery 555 and the mounting box 101 are provided with a corresponding anti-fooling structure to ensure the installation direction of the storage battery 555. When the installation direction of the storage battery 555 is incorrect, the mounting box 101 cannot enter the cabinet body 1 normally.

[0044] The working principle of the above embodiment is as follows:

[0045] First of all, take Figure 1Taking the front side of the cabinet body 1 as the perspective reference, the side where the label of the cabinet body 1 is located is the left side; when the worker needs to install the storage battery 555, the worker controls the electric slide rod 10101 in the cabinet body 1 to drive the installation box 101 to move forward and extend out through the control system in the cabinet body 1. Then the worker holds the handle of the storage battery 555 by hand, aligns the card slot on the lower side of the storage battery 555 with the card block 10107 on the installation box 101, and then puts the storage battery 555 into the installation box 101. Then, the worker controls the electric slide rod 10101 in the cabinet body 1 to drive the installation box 101 to move backward and reset through the control system in the cabinet body 1. When it is necessary to take out the storage battery 555, only need to control the electric slide rod 10101 in the cabinet body 1 to drive the installation box 101 to move forward and extend out through the control system in the cabinet body 1. Then the worker holds the handle of the storage battery 555 by hand and pulls out the storage battery 555; the installation and disassembly are convenient, which is convenient for the worker to overhaul and maintain the storage battery 555; it should be noted here that during the process of the installation box 101 moving backward and resetting, the conductive block 102 enters the connection groove 1003 and is in close contact with the conductive sheet in the connection groove 1003. Then the sealing block 10102 will block the connection groove 1003 to prevent rainwater from entering the connection groove 1003 on rainy days and affecting the conductive effect of the conductive block 102; after the installation box 101 is reset, the storage battery 555 is electrically connected to the control system in the cabinet body 1 through the conductive block 102;

[0046] During the working state, as Figures 2-6 shown: There is a heat dissipation cavity 1001 between two adjacent storage batteries 555, which increases the heat dissipation space of the cabinet body 1, is beneficial to the overall heat dissipation of the cabinet body 1, and reduces the probability of thermal runaway of the storage battery 555; and during the working state, the rotating plate 103 is in a rotating and open state, and the heat dissipation holes of the heat dissipation plate 106 are also in an open state. Then the micro air pump 104 will work. At this time, the connecting pipe between the micro air pump 104 and the air inlet 10103 is in an open state, and the connecting pipe with the memory 105 is in a closed state. At this time, the outside air enters from the air inlet 10103, and then is discharged through the air outlet 10104. Then the air flow reaches the heat dissipation plate 106 through the flow groove 10105 and is discharged from the cabinet body 1 through the open heat dissipation holes in the heat dissipation plate 106 and the rotating and open rotating plate 103. During this process, the air flow circulates around the side wall of the storage battery 555, and then the heat generated by the storage battery 555 during operation is taken out of the cabinet body 1 by the flowing air flow, which greatly improves the heat dissipation effect of the equipment and reduces the probability of thermal runaway of the storage battery 555;

[0047] When the monitor 3 detects that an individual battery 555 is aging, the monitor 3 controls the alarm system to issue an alarm, prompting the staff to replace the aging battery 555 in a timely manner. When the battery 555 is not replaced in a timely manner, the internal resistance of the aging battery 555 increases, resulting in more heat generated during the charging process. If overcharging continues, the heat accumulation may lead to thermal runaway, that is, the internal temperature of the battery rises sharply, triggering a fire or explosion. When the battery 555 experiences thermal runaway, the monitor 3 issues a command to the control system inside the cabinet 1. At this time, the control system inside the cabinet 1 controls the electric slide rod 10101 to drive the corresponding mounting box 101 to move forward and extend out, taking out the other batteries 555 that have not experienced thermal runaway from the cabinet 1. At this time, as Figure 7 shown: The mounting box 101 moves forward and extends out. At this time, the front side of the cabinet 1 is sealed by the fixing rod 201, the heat dissipation plate 106, and the mounting box 101, and the rotating plate 103 will rotate and reset, thereby sealing the rear side of the cabinet 1. Since the pressure relief port of the battery 555 faces the rotating plate 103, and the mounting box 101 is made of a flame-retardant material, the rotating plate 103 consumes the energy of the pressure relief port of the battery 555 to prevent the battery 555 from exploding due to excessive internal pressure. At this time, the cabinet 1 is in a sealed state to prevent the battery 555 experiencing thermal runaway from affecting other batteries 555; then the control electric control valve switches the intake pipe, and then makes the micro air pump 104 continue to work. However, at this time, the connecting pipe between the micro air pump 104 and the air inlet 10103 is in a closed state, and the connecting pipe with the memory 105 is in an open state. At this time, the micro air pump 104 will suck the fire extinguishing agent in the memory 105 and discharge it through the air outlet 10104. At this time, the heat dissipation holes on the heat dissipation plate 106 at the rear of the mounting box 101 inside the cabinet 1 are in a closed state. Therefore, the fire extinguishing agent sprayed out from the air outlet 10104 in these mounting boxes 101 will flow in the flow groove 10105 on the side wall of the battery 555, directly cooling and extinguishing the battery 555 experiencing thermal runaway. And the heat dissipation plate 106 at the rear of the mounting box 101 outside the cabinet 1 is in an open state. Therefore, the fire extinguishing agent sprayed out from the air outlet 10104 in these mounting boxes 101 will be discharged into the cabinet 1 through the flow groove 10105 and the heat dissipation holes on the heat dissipation plate 106, thereby cooling and extinguishing the battery 555 experiencing thermal runaway in the cabinet 1 and improving the fire extinguishing effect; at the same time, both the rear side of the cabinet 1 and the heat dissipation plate 106 are made of flame-retardant materials. Therefore, when the battery 555 inside the cabinet 1 experiences thermal runaway and explodes, it will not harm the batteries 555 outside the cabinet 1, and the battery 555 experiencing thermal runaway will not affect other batteries 555, reducing losses;

[0048] When the installation box 101 is located inside the cabinet body 1, at this time, the fixing block 108 moves into the installation box 101 under the extrusion of the cabinet body 1. At this time, the spring 109 is compressed and contracted. When the installation box 101 extends forward, the fixing block 108 is no longer under pressure, and the spring 109 extends and resets, thereby squeezing the fixing block 108 into the fixing groove 20102. Moreover, the electric slide rod 10101 will also slide into the corresponding slide groove 20101. At this time, the installation box 101 is connected to the fixing rod 201 through the fixing block 108 and the electric slide rod 10101, preventing the short-circuit burning of the lines inside the cabinet body 1 caused by the combustion and explosion of the battery 555 due to thermal runaway, resulting in the loss of connection and fixation of the electric slide rod 10101 to the installation box 101 and the problem of the installation box 101 falling off;

[0049] On the basis of the above technical effects, the present invention also has the following advantages:

[0050] Grip handles 10106 are provided on the front sides of the installation boxes 101. When the electric slide rod 10101 is damaged, after the worker receives the alarm signal sent by the monitor 3 and arrives at the scene, the worker can also hold the grip handle 10106 to pull out the corresponding installation box 101;

[0051] A photovoltaic panel 2 is fixedly connected to the upper side of the cabinet body 1. The photovoltaic panel 2 can absorb sunlight to ensure the normal operation of the control system and the touch screen, and when there is no power input to the device, it can slowly charge the battery 555, effectively preventing the battery 555 from running out of power and ensuring its normal operation;

[0052] Connectors 107 are fixedly connected to the front sides of each installation box 101. Users can connect the devices that need electricity to the battery 555 inside the installation box 101 through the connectors 107, and then control the independent operation of this battery 555 through the control system inside the cabinet body 1.

[0053] Embodiment 2

[0054] On the basis of Embodiment 1, as Figure 8 and Figure 9 shown, it further includes sliders 202 and fixing screws 203; two fixing rods 201 are commonly fixedly connected with two symmetrically arranged sliders 202 up and down; each slider 202 is slidably connected to the cabinet body 1; two fixing screws 203 are bolted to each slider 202; four corresponding threaded grooves are opened on the front side of the cabinet body 1. In the initial state, each fixing screw 203 is tightened in the corresponding threaded groove, thereby fixing the slider 202 and the fixing rod 201 on the cabinet body 1.

[0055] The working principle of the above embodiment is as follows:

[0056] After the installation box 101 is extended forward by the electric sliding rod 10101 described in Embodiment 1, at this time, the fixing block 108 is squeezed into the fixing groove 20102, and the electric sliding rod 10101 also slides into the corresponding sliding groove 20101. The installation box 101 is connected to the fixing rod 201. When subsequent workers need to replace or repair the battery 555 damaged by thermal runaway in the cabinet 1; as Figure 9 shown, the worker can unscrew the fixing screw 203 on the slider 202, then slide the fixing rod 201 and the slider 202 to the left, thereby driving the installation box 101 outside the cabinet 1 to slide to the left until Figure 9 the state shown in the figure: facilitating the worker to replace the battery 555 damaged by thermal runaway in the cabinet 1, and at the same time facilitating the worker to clean and repair the cabinet 1.
