[0031] As Figure 2As shown in the figure, multiple charging positions 21 are arranged side by side with a transfer position 22 and an isolation room 23. The transfer position 22 is arranged at one end of the multiple charging positions 21 close to the battery swapping channel. The isolation room 23 is arranged at one end of the multiple charging positions 21 far from the battery swapping channel, and a maintenance position 24 and an emergency treatment position 25 are arranged in the isolation room 23. A composite detection device 30, a fire extinguishing device 40 and a battery fire disposal box 50 are arranged in each of the charging positions 21 and the transfer position 22.

It should be noted that the number of the composite detectors 31 and the hydrogen detectors 32 in each charging position 21 and the transfer position 22 can be set according to actual needs, which can be one or multiple, preferably 2 or more.

[0033] In a preferred embodiment of the present invention, the alarm rules of the composite detector are as follows. Of course, those skilled in the art know that different alarm rules can be set according to actual situations, and these all fall within the protection scope of the present invention.

[0034]

[0035] In this preferred embodiment, the fire extinguishing device 40 includes a dry powder / foam / water-based fire extinguisher 41, an aerosol fire extinguisher, a fire blanket 42, a sand box, and a water spray control valve arranged on the branch fire water pipe 81.

Of course, according to actual needs, only some of the foregoing fire extinguishing devices 40 can also be set.

[0036] In Figure 2In the preferred embodiment shown, the intelligent fire protection system of the battery swapping station further includes an alarm device 90, and the alarm device 90 is communicatively connected to the central fire protection controller 60; the central fire protection controller 60 is configured to control the alarm device 90 to give an alarm when receiving the first-level alarm signal. In the preferred embodiment of the present invention, the alarm device may be an audible and visual alarm device, and of course, it may also be an audible alarm device or a photoelectric alarm device. At least one, preferably multiple, alarm devices 90 may be provided, and their positions may be any bin, battery swapping channel or the channel connecting each bin, as long as it can be easily perceived by the staff.

[0037] In the preferred embodiment of the present invention, the specific use of the fire extinguishing device 40 may be, for example, remotely controlled by the central fire protection controller 60 or manually opening the valve directly (such as dry powder / foam / water-based fire extinguishers, aerosol fire extinguishers), or directly used manually (such as a sandbox, a fire blanket). For example, in the preferred embodiment of the present invention, the valves of the dry powder / foam / water-based fire extinguisher 41 and the aerosol fire extinguisher are communicatively connected to the central fire protection controller 60; the central fire protection controller 60 controls the valve 51 of the corresponding battery fire disposal box 50 to open, controls the on / off of the corresponding water injection control valve 83, and controls the valve of the corresponding dry powder / foam / water-based fire extinguisher 41 and / or the aerosol fire extinguisher to open when receiving the second-level alarm signal. In a further preferred embodiment of the present invention, the water spray control valve provided on the fire water pipe branch 81 is also communicatively connected to the central fire protection controller 60, and the central fire protection controller 60 controls the valve 51 of the corresponding battery fire disposal box 50 to open, controls the corresponding water injection control valve 83 to open, controls the valves of the corresponding dry powder / foam / water-based fire extinguisher 41 and the aerosol fire extinguisher to open, and at the same time controls the water spray control valve to open to spray water to the corresponding bin when receiving the second-level alarm signal.

[0038] In another preferred embodiment of the present invention, the central fire protection controller 60 further includes a command input device 91 for receiving user commands. The command input device 91 can be an emergency control button set in the monitoring room. In other preferred embodiments of the present invention, the emergency control button can also use a high-brightness LED light to display the working status, and adopt a two-wire wiring system. When the central fire protection controller 60 receives the first-level alarm signal, or does not receive any alarm signal, but the staff believes that a fire has occurred and needs to be dealt with immediately, the emergency control button can be pressed to input the user command. At this time, the central fire protection controller 60 is used to control the corresponding valve 51 of the battery fire disposal box 50 to open, control the corresponding water injection control valve 83 to open, control the corresponding valves of the dry powder / foam / water-based fire extinguisher 41 and the aerosol fire extinguisher to open, and control the water spray control valve to open when receiving the user command. Of course, when the fire is over or the staff finds that a secondary alarm signal is generated due to a false alarm, they can also press the emergency control button to input user instructions. At this time, the central fire protection controller 60 is used to control the corresponding valve 51 of the battery fire disposal box 50 to close, control the corresponding water injection control valve 83 to close, control the corresponding valves of the dry powder / foam / water-based fire extinguisher 41 and the aerosol fire extinguisher to close, and control the water spray control valve to close when receiving the user instruction.

[0039] In a further preferred embodiment of the present invention, a battery swapping robot 90 provided within the battery swapping station can be used to extinguish dangerous battery fires. For example, the battery swapping robot 90 is communicatively connected to the central fire protection controller 60; upon receiving user instructions, the central fire protection controller 60 is configured to grasp the corresponding battery and transport it to a fire water tank located in an isolation room.

[0040] Therefore, in the present invention, different logic can be used for battery alarms at different locations. When a battery fire occurs in the charging compartment 20, the corresponding battery fire disposal box 50 can be used to deal with it. When a battery fire occurs in the battery swap channel, the battery swap robot 90 can be used to clamp the corresponding battery and transport it to the fire water tank located in the isolation room.

[0041] The following combination Figure 1-2, a preferred embodiment of the intelligent fire protection system for the battery swapping station of the present utility model is described as follows. In a preferred embodiment of the present utility model, when the central fire protection controller 60 receives a first-level alarm signal generated by the composite detector 31 located in any one or more charging bays 21, the alarm device is activated to give an audible and visual alarm and emit an alarm sound. When the central fire protection controller 60 receives a second-level alarm signal generated by the composite detector 31 or the hydrogen detector 32 located in any one or more charging bays 21, the fire extinguishing process is started, the countdown is started, and the valve 51 of the battery fire protection disposal box 50 in the corresponding charging bay 21 is opened after a delay of 30 s (the time can be adjusted according to requirements). During the delay period, if the on-duty personnel on-site check and judge that there is no fire, the emergency start / stop button can be used for emergency stop.

[0042] When someone enters the protected area (i.e., any bay), it can be switched to the manual start state. When the central fire protection controller 60 receives any alarm signal, the central fire protection controller 60 will not control the operation of any fire extinguishing device, nor will it control the valve of the battery fire protection disposal box. The staff needs to judge by themselves and start or stop emergently through the emergency start / stop button. When the staff presses the emergency start button, the countdown is started, and the valve 51 of the battery fire protection disposal box 50 in the corresponding charging bay 21 is opened after a delay of 30 s (the time can be adjusted according to requirements). During the delay period, if the on-duty personnel on-site check and judge that there is no fire, the emergency start / stop button can be used for emergency stop.

[0043] When no staff member discovers an emergency fire, the emergency start button can be pressed, the countdown is started, and the valve 51 of the battery fire protection disposal box 50 in the corresponding charging bay 21 is opened after a delay of 30 s (the time can be adjusted according to requirements). During the delay period, if the on-duty personnel on-site check and judge that there is no fire, the emergency start / stop button can be used for emergency stop. On the premise that the personnel confirm safety, auxiliary fire extinguishing can be carried out through the equipped fire hydrant, fire blanket, fire extinguisher, and sand box.

[0044] In another preferred embodiment of the present utility model, when the central fire controller 60 receives a first-level alarm signal generated by the composite detector 31 located in any one or more of the charging compartments 21, it activates the alarm device to give an audible and visual alarm and emit an alarm sound. When the central fire controller 60 receives a second-level alarm signal generated by the composite detector 31 or the hydrogen detector 32 located in any one or more of the charging compartments 21, it activates the fire extinguishing process, starts the countdown, and after a delay of 30 s (the time can be adjusted according to requirements), opens the valve 51 of the battery fire control box 50 in the corresponding charging compartment 21, controls the opening of the corresponding water injection control valve 83, controls the opening of the valves of the corresponding dry powder / foam / water-based fire extinguisher 41 and the aerosol fire extinguisher, and controls the opening of the water spray control valve. During the delay period, if a duty officer on-site checks and determines that there is no fire, the emergency start / stop button can be used for emergency stop.

[0045] In a preferred embodiment of the present utility model, the intelligent fire protection system of the battery swapping station is applicable to surface battery swapping stations. In another preferred embodiment of the present utility model, the intelligent fire protection system of the battery swapping station is applicable to underground battery swapping stations. The following further illustrates with the intelligent fire protection system of the underground battery swapping station as an example.

[0046] As described above, the intelligent fire protection system of the underground battery swapping station also includes multiple charging compartments, transfer compartments, composite detection devices, fire extinguishing devices, and battery fire control boxes respectively arranged in each charging compartment and transfer compartment, an isolation room, and a central fire controller. Its structure is similar to the foregoing embodiments, except that each compartment is arranged in a chamber, and fire doors are arranged in each chamber, and a ventilation system is provided.

[0047] In the intelligent fire protection system of the underground battery swapping station, it is required that the temperature of the charged lithium battery ≤ 60 °C, the ambient temperature and the methane concentration in the air ≤ 0.5%, the CO concentration ≤ 0.0024%, the hydrogen concentration ≤ 0.5%, and harmful gas monitoring of the smoke concentration. After exceeding the standard specified value, the composite detection device will correspondingly generate a first-level alarm signal or a second-level alarm signal. The central fire controller is used to control the alarm device to give an alarm when receiving the first-level alarm signal.

[0048] When the central fire controller receives the first-level alarm signal detected by the composite detection device, it controls the charging pile in the swapping station to automatically disconnect the charging and controls the alarm device to start the sound and light alarm. At this time, the duty personnel confirm whether the temperature value detected by the composite detection device has risen. If not, an alarm cancellation instruction is input through the instruction input device, and the driver is notified to hoist the vehicle to the shaft for inspection. If the composite detection device detects that the temperature value has risen, a fire handling instruction is input through the instruction input device, and the on-site full flooding treatment of the battery is started, that is, the valve 51 of the corresponding battery fire disposal box 50 is controlled to open and the corresponding water injection control valve 83 is controlled to open. At this time, the damaged battery will fall into the battery fire disposal box 50, and at the same time, the water injection control valve 83 injects water into the battery fire disposal box 50, so that the fire can be accurately detected and effectively extinguished in real time.

[0049] When the central fire controller receives the second-level alarm signal detected by the composite detection device, it starts the fire extinguishing device and the valve on the fire fighting branch to perform fire sprinkler cooling, manually or automatically close the fire door, input a fire handling instruction through the instruction input device, control the swapping robot to hoist and transfer the battery to the emergency disposal water tank for full flooding treatment, and at the same time, link the underground ventilation system communicatively connected to the central fire controller to act.

[0050] Certainly, the central fire controller can also be communicatively connected to output devices, such as a microphone or a display screen. At the same time, on the premise of ensuring safety, the staff can use the equipped fire blankets and fire extinguishers to assist in extinguishing the fire.

[0051] Implementing the intelligent fire protection system for the swapping station of the present utility model can accurately detect the fire and effectively extinguish the fire in real time, and is especially suitable for the swapping station. Further, since various fire extinguishing strategies can be adopted, different fires can be dealt with and the fire protection requirements can be met. Furthermore, the intelligent fire protection system for the swapping station of the present utility model can be applied to above-ground or underground swapping stations, and has a wide range of application scenarios.

[0052] Although the present utility model is described through specific embodiments, those skilled in the art should understand that various transformations and equivalent substitutions can be made to the present utility model without departing from the scope of the present utility model. In addition, for specific situations or materials, various modifications can be made to the present utility model without departing from the scope of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of the present utility model.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
