[0029] The working principle of the above embodiment is as follows: First, Figure 110101 is the viewing angle reference, where the side where the cabinet 1 number is located is the left side; when the worker needs to install the battery 555, the worker controls the electric slide bar 10101 through the control system in the cabinet 1 to drive the installation box 101 to move forward and extend, and then the worker holds the handle of the battery 555, aligns the card slot on the lower side of the battery 555 with the card block 10107 on the installation box 101, and then puts the battery 555 into the installation box 101, and then controls the electric slide bar 10101 through the control system in the cabinet 1 to drive the installation box 101 to move backward and reset. When the battery 555 needs to be removed, it is only necessary to control the electric slide bar 10101 through the control system in the cabinet 1 to drive the installation box 101 to move forward and extend. The installation box 101 moves forward and extends out, and then the worker lifts the handle of the battery 555 and pulls out the battery 555; it is convenient to install and disassemble, and it is convenient for workers to inspect and maintain the battery 555; it should be noted that in 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, and 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 battery 555 is electrically connected to the control system in the cabinet 1 through the conductive block 102; When in working state, Figure 2-Figure 6 As shown in the figure: a heat dissipation cavity 1001 is left between two adjacent batteries 555, which increases the heat dissipation space of the cabinet 1, is beneficial to the overall heat dissipation of the cabinet 1, and reduces the probability of thermal runaway of the battery 555; and in the working state, the rotating plate 103 is rotated to open, and the heat dissipation holes of the heat dissipation plate 106 are also in an open state, and then the micro air pump 104 will work, at this time, the connection pipe between the micro air pump 104 and the air inlet 10103 is in an open state, and the connection pipe with the storage 105 is in a closed state, at this time the external air The air enters from the air inlet 10103 and then is discharged from the air outlet 10104. Then, the airflow passes through the circulation slot 10105 to reach the heat sink 106, and is discharged from the cabinet 1 through the heat dissipation holes opened in the heat sink 106 and the rotating plate 103 that is rotated and opened. In this process, the airflow circulates around the side wall of the battery 555, and then the heat generated by the battery 555 when working is brought out of the cabinet 1 through the flowing airflow, which greatly improves the heat dissipation effect of the equipment and reduces the probability of thermal runaway of the battery 555. When the monitor 3 detects that individual batteries 555 are aging, the monitor 3 controls the alarm system to sound an alarm, prompting the staff to replace the aged batteries 555 in time. If the batteries 555 are not replaced in time, the internal resistance of the aged batteries 555 increases, resulting in more heat generated during the charging process. If overcharging continues, the heat accumulation may cause thermal runaway, that is, the internal temperature of the battery rises sharply, causing a fire or explosion. When the battery 555 is in thermal runaway, the monitor 3 will send a command to the control system in the cabinet 1. At this time, the control system in the cabinet 1 controls the electric slide bar 10101 to drive the corresponding installation box 101 to move forward and extend, and take other batteries 555 that have not caused thermal runaway out of the cabinet 1. At this time, if Figure 7 As shown: the installation 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 sink 106 and the installation box 101, and the rotating plate 103 will rotate and reset, thereby sealing the back side of the cabinet 1. Since the pressure relief port of the battery 555 faces the rotating plate 103, and the installation box 101 is set to a flame-retardant material, the energy of the pressure relief port of the battery 555 is consumed by the rotating plate 103 to prevent the battery 555 from exploding due to excessive internal air pressure. At this time, the cabinet 1 is in a sealed state to prevent the battery 555 that has thermal runaway from affecting other batteries 555; then the electronically controlled valve is controlled to switch the air inlet pipe, and the micro air pump 104 continues to work, but 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 storage 105 is in an open state. At this time, the micro air pump 104 will absorb the fire extinguishing agent in the storage 105 and discharge it through the air outlet 10104. At this time, the micro air pump 104 is located in the cabinet. The heat dissipation holes on the heat dissipation plate 106 at the rear side of the installation box 101 in the cabinet 1 are in a closed state, so the fire extinguishing agent sprayed from the air outlets 10104 in these installation boxes 101 will flow in the flow grooves 10105 on the side walls of the storage battery 555, directly cooling and extinguishing the storage battery 555 that has thermal runaway, while the heat dissipation plate 106 at the rear side of the installation box 101 outside the cabinet 1 is in an open state, so the fire extinguishing agent sprayed from the air outlets 10104 in these installation boxes 101 The heat will be discharged into the cabinet 1 through the flow slot 10105 and the heat dissipation holes on the heat dissipation plate 106, thereby cooling down and extinguishing the battery 555 in thermal runaway in the cabinet 1, thereby improving the fire extinguishing effect; at the same time, the rear side of the cabinet 1 and the heat dissipation plate 106 are made of flame-retardant materials, so that when the battery 555 in the cabinet 1 explodes due to thermal runaway, it will not harm the battery 555 outside the cabinet 1. The battery 555 in thermal runaway will affect other batteries 555, thereby reducing losses; When the installation box 101 is located in the cabinet 1, the fixing block 108 is squeezed by the cabinet 1 and moves into the installation box 101. At this time, the spring 109 is compressed and contracted. When the installation box 101 extends forward, the fixing block 108 is no longer compressed, and the spring 109 stretches and resets, thereby squeezing the fixing block 108 into the fixing groove 20102, and the electric slide bar 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 bar 10101, so as to prevent the battery 555 from burning or exploding due to thermal runaway, causing the circuit in the cabinet 1 to short-circuit and burn, causing the electric slide bar 10101 to lose its connection and fixation with the installation box 101, and causing the installation box 101 to fall off. On the basis of the above technical effects, the present invention also has the following advantages: A handle 10106 is provided on the front side of each installation box 101. When the electric slide bar 10101 is damaged, after receiving the alarm signal from the monitor 3 and rushing to the scene, the worker can also pull out the corresponding installation box 101 by holding the handle 10106; A photovoltaic panel 2 is fixedly connected to the upper side of the cabinet 1, which can absorb sunlight to ensure the normal operation of the control system and the touch screen, and slowly charge the battery 555 when there is no power input to the device, effectively preventing the battery 555 from running out of power and ensuring its normal operation; A connector 107 is fixedly connected to the front side of each installation box 101. The user can connect the device that needs electricity to the battery 555 in the installation box 101 through the connector 107, and then control the battery 555 to work independently through the control system in the cabinet 1.

[0030] Example 2 On the basis of Example 1, Figure 8 and Fig. 9 As shown, it also includes a slider 202 and a fixing screw 203; two fixing rods 201 are fixedly connected to two sliders 202 that are symmetrical up and down; each slider 202 is slidably connected to the cabinet 1; each slider 202 is bolted with two fixing screws 203; four corresponding threaded grooves are opened on the front side of the cabinet 1, and 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 1.

[0031] The working principle of the above embodiment is as follows: After the installation box 101 is extended forward by the electric slide bar 10101 as described in Example 1, the fixing block 108 is squeezed into the fixing groove 20102, and the electric slide bar 10101 also slides into the corresponding slide groove 20101, and 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; Fig. 9As shown in the figure, the worker can unscrew the fixing screw 203 on the slider 202, and 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. Fig. 9 The state shown is convenient for workers to replace the damaged storage battery 555 caused by thermal runaway in the cabinet 1 , and also convenient for workers to clean and repair the cabinet 1 .
