The conduit first end 224 is connected with the sub-silo housing 111 and is in fluid communication with both drain openings 114 such that the drain sub-conduit 221 is in fluid communication with the sub-silo receiving cavity 112 of the corresponding sub-silo 11. Since the lower edge of the drain opening 114 of the sub-bin housing 111 of the sub-bin 11 is disposed at a height greater than 0 above the bottom of the sub-bin accommodating chamber 112, the pipe first end 224 has a predetermined distance greater than 0 from the bottom of the sub-bin accommodating chamber 112. The five drainage branch pipes 222 extend in the transverse direction, and the heights thereof are respectively set to correspond to five levels in the cabinet accommodating cavity and are set near the bottom of the sub-bin 11 of each level. The drain leg 222 on each level is connected to the second pipe ends 226 of the eight drain subducts 221 on that level. The main drain pipe 223 extends in the longitudinal direction, is disposed near the middle of the five drain branch pipes 222, and is in fluid communication with the five drain branch pipes 222, respectively. The lower end of the main drain pipe 223 is in fluid communication with the second inlet 132 of the second water storage means 13.

The drainage system 22 is configured such that water in the sub-tank 11 can flow into the second water storage device 13 through the drainage sub-pipe 221, the drainage branch pipe 222, and the drainage main pipe 223. Specifically, when the height of the water in the sub-tank 11 is greater than the height of the lower edge of the drain opening 114 of the sub-tank housing 111 of the sub-tank 11, the water in the sub-tank 11 flows through the drain opening 114 into the drain sub-pipe 221 communicating with the drain opening 114, and flows down to the drain branch pipe 222 communicating with the drain sub-pipe 221, down to the drain main pipe 223 communicating with the drain branch pipe 222, and finally flows into the second water storage means 13 communicating with the drain main pipe 223 through the second inlet 132 of the second water storage means 13.

It should be noted that although in the embodiment of the present invention, each sub-chamber 11 includes two drainage openings 114 and two drainage sub-pipes 221 are communicated with the two drainage openings 114, it can be understood by those skilled in the art that in other embodiments, each sub-chamber 11 may include any number of drainage openings 114 and a corresponding number of drainage sub-pipes 221 are communicated with the drainage openings 114 in one sub-chamber 11.

The slot 102 has an upward slot opening. The tank connecting pipe 103 is used for connecting the tank 102 on the cabinet door 101 with the second water storage device 13. The tank connecting pipe 103 is a hose so that the cabinet door 101 can still be communicated with the cabinet door 101 and the second water storage device 13 when the cabinet door is opened or closed for many times. The tank connecting conduit 103 has a tank connecting conduit first end 105 and a tank connecting conduit second end 106 disposed opposite each other, the tank connecting conduit first end 105 being in fluid communication with the tank 102, and the tank connecting conduit second end 106 being in fluid communication with the second collection port 134 at the front side of the second water storage means 13. Wherein the tank connection conduit first end 105 is provided at a lower end of the tank 102 to enable water contained in the tank 102 to flow from the tank 102 to the tank connection conduit 103.

The sump 102 and the sump connection pipe 103 serve to collect water splashed on the inside of the cabinet door 101 by the water supply system 21 and to deliver the collected water to the second water storage means 13. Specifically, when the spray head 215 sprays water to the sub-compartment 11, the water may splash onto the inner side of the cabinet door 101 through the sub-compartment opening 113 at the front side of the sub-compartment housing 111. The water splashed onto the inner side of the cabinet door 101 flows down the inner side of the cabinet door 101 due to its own weight and is finally collected in the trough 102 through the trough opening. The water collected by the sump 102 flows toward the sump connection pipe 103 along an inclined path defined by the sump 102 and finally flows into the second water storage means 13 through the second collection port 134 connected to the sump connection pipe 103.

The control device 31 activates the pressurizing device 214 based on the temperature signal and opens the solenoid valve 216 corresponding to the sub-tank accommodating chamber 112. The smoke induction device is arranged at the top of the cavity of the cabinet body. The smoke sensing device is communicatively connected to the control device 31 and is configured to send a smoke signal to the control device 31 when the smoke sensing device senses smoke. The control unit 31 activates the power unit 232 and opens the solenoid valve 216 based on the smoke signal.

It should be noted that, although the control device 31 activates the power device 232 and opens the solenoid valve 216 based on the temperature signal and the smoke signal provided by the temperature sensing device 32 and the smoke sensing device, respectively, in the above examples, it is understood that the control device 31 may also deactivate the power device 232 and close the solenoid valve 216 based on the temperature signal and the smoke signal.

The first liquid level sensor 121 is disposed at the top of the first water storage device 12 for detecting the liquid level of water inside the first water storage device 12. The first liquid level sensor 121 is configured to: when the liquid level height of the water in the first water storage device 12 is equal to or lower than the first liquid level low level height, the first liquid level sensor 121 transmits a first liquid level low level signal to the control device 31; and when the liquid level height of the water in the first water storage device 12 is equal to or higher than the first liquid level height, the first liquid level sensor 121 transmits a first liquid level height signal to the control device 31.

The second liquid level sensor 131 is disposed at the top of the second water storage device 13 for detecting the liquid level of the water inside the second water storage device 13. The second liquid level sensor 131 is configured to: when the liquid level height of the water in the second water storage device 13 is equal to or lower than the second liquid level low level height, the second liquid level sensor 13 transmits a second liquid level low level signal to the control device 31; and when the level of the water in the second water storage means 13 is equal to or higher than the second level height, the second level sensor 131 transmits a second level height signal to the control means 31.

Furthermore, the control device 31 is capable of controlling the starting and stopping of the charging circuitry for charging the batteries in the battery cabinet.

The operation of the cabinet assembly, and in particular the fire protection and control mechanisms, will now be described.

When the battery cabinet is operating normally, the control device 31 controls the charging circuitry to charge the batteries in the battery cabinet. The first water storage means 12 contains water, the electromagnetic valve 216 in the water supply system 21 is closed, the water replenishing electromagnetic valve is closed, and the pressurizing means 214 in the water supply system 21 and the power means 232 in the water return system 23 are stopped. The temperature sensing device 32 located in each sub-bin 11 detects the temperature in the corresponding sub-bin 11, and the smoke sensing device located at the top of the cabinet accommodating cavity detects whether smoke exists in the cabinet accommodating cavity.

When the temperature sensing device 32 in a certain sub-compartment 11 detects a temperature higher than a preset temperature and/or when the smoke sensing device detects the presence of smoke in the cabinet cavity, the temperature sensing device 32 and/or the smoke sensing device sends a temperature signal and/or a smoke signal to the control device 31. The control device 31 is capable of disabling the charging circuitry based on the received temperature signal and/or smoke signal and causing the backup power source 35 to be enabled to selectively provide power to the pressurizing device 214 and the motive device 232. The control device 31 activates the pressurizing device 214 and opens the solenoid valve 216 correspondingly disposed in the sub-compartment 11, so that the pressurizing device 214 pressurizes the water from the first water storage device 12 and sprays the pressurized water to the sub-compartment 11 through the corresponding spray head 215, thereby performing rapid physical cooling on the batteries in the sub-compartment 11.

After the spray head 215 sprays water to the corresponding sub-bin 11, a certain amount of water is accumulated in the sub-bin accommodating chamber 112 of the sub-bin 11 since the bottom of the sub-bin accommodating chamber 112 is disposed obliquely with respect to the horizontal direction and the lower edge of the water discharge opening 114 is disposed at a height greater than 0 above the bottom of the sub-bin accommodating chamber 112. When the level of the water accumulated in the sub-bin accommodating chamber 112 rises above the lower edge of the drainage opening 114 of the sub-bin 11, the water in the sub-bin accommodating chamber 112 flows into the drainage sub-pipe 221 communicating with the drainage opening 114 through the drainage opening 114 of the sub-bin 11, and flows down to the drainage branch pipe 222 communicating with the drainage sub-pipe 221, flows down to the drainage main pipe 223 communicating with the drainage branch pipe 222, and finally flows into the second water storage means 13 communicating with the drainage main pipe 223 through the second inlet 132 of the second water storage means 13. Furthermore, some water will splash onto the inside of the cabinet door 101 through the sub-bin opening 113. The water splashed onto the inner side of the cabinet door 101 flows down the inner side of the cabinet door 101 due to its own weight and is finally collected in the trough 102 through the trough opening. The water collected by the sump 102 flows toward the sump connection pipe 103 along an inclined path defined by the sump 102 and finally flows into the second water storage means 13 through the second collection port 134 connected to the sump connection pipe 103.

When the first level low signal indicates that the level of water in the first water storage means 12 is equal to or lower than the first level low height, which indicates that the amount of water in the first water storage means 12 is small, the first level sensor 121 transmits the first level low signal to the control means 31. The control device 31 activates the power device 232 on the basis of the signal, so that the water in the second water storage device 13 is conveyed upwards to the first water storage device 12 through the water return pipe 231 in the water return system 23 to replenish the water in the first water storage device 12.

After a certain time of operation of the fire fighting entity, if the temperature sensing device 32 detects a temperature lower than the preset temperature and when the smoke sensing device detects that there is no more smoke in the cabinet volume (which indicates that the battery has been sufficiently physically cooled), the temperature sensing device 32 and the smoke sensing device no longer send a temperature signal or a smoke signal to the control device 31. The control device 31 controls the solenoid valve 216 to close and controls the pressurizing device 214 to stop working. Thereby, the fire fighting entity no longer sprays water into the sub-silo 11. At this time, a maintainer of the battery cabinet can wait for the maintenance detection of the battery cabinet.

After the fire-fighting entity no longer sprays water to the sub-tank 11, the first and second liquid level sensors 121 and 131 continue to detect the liquid levels in the first and second water storage devices 12 and 13. If the level of water in the second water storage means 13 is equal to or lower than the second level-lower height at this time, the control means 31 opens the water replenishment solenoid valve so that the second water storage means 13 receives water from the public fire fighting pipe to replenish the amount of water in the second water storage means 13. Since the power unit 232 continues to operate, the power unit 232 will replenish the water in the second water storage device 13 into the first water storage device 12. When the liquid level of the water in the first water storage device 12 is equal to or higher than the first liquid level high level, the first liquid level sensor 121 transmits a first liquid level high level signal to the control device 31, and the control device 31 turns off the power device 232. At this time, sufficient water has been stored in the first water storage means 12. The water continues to be injected into the second water storage means 13 through the common fire fighting pipe until the level of the water in the second water storage means 13 is equal to or higher than the second level height. The second level sensor 131 transmits a second level high signal to the control device 31, and the control device 31 closes the water replenishment solenoid valve based on the signal.
