[0046] Combination Figure 1 , Figure 6 and Figure 7 As shown, the embodiment of the present disclosure provides a fire extinguishing device for a fire protection charging cabinet, which includes one or more charging compartments 101, each of which is provided with a composite detector 102 and a fire extinguishing nozzle; the fire extinguishing device includes: a fire extinguisher 10, which stores a fire extinguishing agent; a control valve assembly 20, wherein the first end of the control valve assembly 20 is connected to the fire extinguisher 10, and the second end of the control valve assembly 20 is connected to the fire extinguishing nozzle of each charging compartment 101 through a second pipeline group 60; a controller; connecting the composite detector 102 and the control valve assembly 20 to realize communication and linkage control between the control valve assembly 20 and the composite detector 102; wherein, when the composite detector 102 sends an alarm signal, the controller makes a fire determination and confirmation, and then controls the flow rate of the fire extinguishing agent sprayed from the fire extinguisher 10 through the control valve assembly 20 to extinguish the fire in the charging compartment 101.

[0047] The fire extinguishing device of the fire protection charging cabinet provided by the embodiment of the present disclosure is adopted, and the fire extinguisher 10 is filled with fire extinguishing agent, and the control valve assembly 20 can be used in conjunction with the composite detector 102 in communication, wherein the first end of the control valve assembly 20 is connected to the fire extinguisher 10, and the second end of the control valve assembly 20 is connected to the fire extinguishing nozzle of each charging compartment 101 through the second pipeline group 60; in this way, when the composite detector 102 of one of the charging compartments 101 sends an alarm signal, the controller makes a fire determination and confirms it, and can adjust the flow rate of the fire extinguishing agent sprayed from the fire extinguisher 10 through the control valve assembly 20, so as to extinguish the fire in the charging compartment 101. In addition, since some lithium batteries may reignite after a fire is extinguished once, the flow rate of the fire extinguishing agent is accurately controlled by the control valve assembly 20 to avoid the fire extinguishing agent from being sprayed out all at once, thereby achieving the purpose of effective fire extinguishing.

[0048] In the embodiment of the present disclosure, the fire extinguisher 10 is filled with a fire extinguishing agent, wherein the fire extinguishing agent includes a gas fire extinguishing agent, a liquid fire extinguishing agent or a solid fire extinguishing agent. Here, a suitable fire extinguishing agent can be selected according to actual environmental requirements and usage requirements. Optionally, a gas fire extinguishing agent is used in the embodiment.

[0049] In the disclosed embodiment, the battery is generally charged at night or when unattended. Therefore, if a fire occurs, the charging cabinet needs to be used to extinguish the fire. Here, lithium batteries are taken as an example. When a lithium battery burns, there is still a possibility of re-ignition even after the fire is successfully extinguished. Therefore, it needs to be extinguished multiple times.

[0050] In the embodiment of the present disclosure, a composite detector 102 is provided in the charging compartment 101, and the situation in the charging compartment 101 is monitored in real time by the composite detector 102, wherein the composite detector 102 can be connected to the control valve assembly 20 through the controller, and the first end of the control valve assembly 20 is connected to the fire extinguisher 10, and the second end of the control valve assembly 20 is connected to the fire extinguishing nozzle of each charging compartment 101 through the second pipeline group 60. In this way, the fire extinguishing agent in the fire extinguisher 10 can enter the charging compartment 101 through the control valve assembly 20.

[0051] In the disclosed embodiment, when the composite detector 102 sends out an alarm signal, after the controller makes a fire determination and confirms it, the control valve assembly 20 can control the flow rate of the fire extinguishing agent sprayed out of the fire extinguisher 10, thereby effectively preventing the fire extinguishing agent in the fire extinguisher 10 from being sprayed out all at once.

[0052] Here, if the lithium battery reignites, the opening of the control valve assembly 20 can be adjusted to achieve different fire extinguishing agent flow rates. For example, the opening of the control valve assembly 20 can be adjusted to a first target opening so that the fire extinguishing agent can be continuously sprayed for a first preset time, and the first preset time includes the time it takes for the composite detector 102 to detect that the lithium battery is burning, extinguishing, and then extinguishing to burning. For another example, the switch state of the control valve assembly 20 can be adjusted so that the fire extinguishing agent can be sprayed at intervals of a preset time. When the composite detector 102 detects that the lithium battery is burning, the control valve assembly 20 is adjusted to an open state; when the composite detector 102 detects that the lithium battery is extinguished, the control valve assembly 20 is adjusted to a closed state.

[0053] Combination Figure 2 and Figure 3 As shown, in some embodiments, the control valve assembly 20 includes a solenoid valve 30 and a distribution valve 40. The solenoid valve 30 is used to communicate with the controller, and the first end of the solenoid valve 30 is connected to the fire extinguisher 10 through the first pipe section 51 of the first pipeline 50; the distribution valve 40 has a valve body inlet 41 and a plurality of valve body outlets 42, wherein the valve body inlet 41 is connected to the second end of the solenoid valve 30 through the second pipe section 52 of the first pipeline 50, and each valve body outlet 42 is connected to each charging compartment 101 through the second pipeline group 60.

[0054] In the embodiment of the present disclosure, the solenoid valve 30 is used for communication connection with the controller, so that the control command issued by the controller can be received in time, wherein the first end of the solenoid valve 30 is connected to the fire extinguisher 10 through the first pipe section 51 of the first pipeline 50, and the second end of the solenoid valve 30 is connected to the valve body inlet 41 of the distribution valve 40 through the second pipe section 52 of the first pipeline 50. In this way, the solenoid valve 30 can control the flow of the fire extinguishing agent flowing into the distribution valve 40. Specifically, when the solenoid valve 30 is in an open state, the fire extinguishing agent can flow into the distribution valve 40, and then flow from the distribution valve 40 into the target charging compartment 101.

[0055] In the disclosed embodiment, the distribution valve 40 has a valve body inlet 41 and a plurality of valve body outlets 42, and each valve body outlet 42 is connected to each charging compartment 101 through a second pipeline group 60. Here, the second pipeline group 60 includes a plurality of second pipelines 61, and each valve body outlet 42 is connected to the corresponding charging compartment 101 through each second pipeline 61. In this way, the fire extinguishing agent in the fire extinguisher 10 can flow into the corresponding target charging compartment 101.

[0056] Specifically, in some embodiments, the distribution valve 40 is used to communicate with the controller. When one or more composite detectors 102 send out an alarm signal, the controller controls the solenoid valve 30 to open or close, and controls the distribution valve 40 to open the valve body outlet 42 of the charging compartment 101 corresponding to the composite detector 102 that sends out the alarm signal.

[0057] In the disclosed embodiment, each charging compartment 101 is individually provided with a composite detector 102, each composite detector 102 is connected to the controller in communication, and the controller is connected to the distribution valve 40 in communication, so that the distribution valve 40 can receive the control instruction issued by the controller; for example, the first composite detector in the first charging compartment sends an alarm signal. At this time, the controller controls the solenoid valve 30 to be in an open state, so that the fire extinguishing agent flows into the distribution valve 40, and correspondingly, controls the distribution valve 40 to open the first valve body outlet, so that the fire extinguishing agent can flow into the first charging compartment, thereby performing a fire extinguishing process.

[0058] Combination Figures 3 to 5 As shown, in some embodiments, the distribution valve 40 includes a valve body 43 and a first blocking member 44. The valve body 43 is provided with a valve body inlet 41 and a plurality of valve body outlets 42; the first blocking member 44 is provided at each valve body outlet 42, and the valve body outlet 42 is controlled by the first blocking member 44 to be in a connected state or a blocked state with the valve body inlet 41.

[0059] In the disclosed embodiment, a separate first blocking member 44 is provided at each valve body outlet 42, so that one of the valve body outlets 42 can be connected to the valve body inlet 41, or multiple valve body outlets 42 can be simultaneously connected to the valve body inlet 41. Here, a valve channel is provided inside the valve body 43, wherein one end of the valve channel is the inlet end, i.e., the valve body inlet 41; multiple outlet ends are provided on the side of the valve channel, i.e., the valve body inlet 41 and multiple valve body outlets 42; the first blocking member 44 can extend into the valve channel, thereby blocking the valve body inlet 41 and the valve body outlet 42; the first blocking member 44 can also be moved out of the valve channel, thereby connecting the body inlet 41 and the valve body outlet 42.

[0060] Combination Figure 5 As shown, in some embodiments, the first blocking member 44 includes a fixing frame 441, a pressing screw 442, a push rod 443 and a temperature sensing component 444. The fixing frame 441 is arranged on the valve body 43; the pressing screw 442 is arranged on the fixing frame 441; the push rod 443 has its bottom end located on the valve body outlet 42 side and its top end located on the fixing frame 441 side; the temperature sensing component 444 is arranged between the push rod 443 and the pressing screw 442; wherein, when the composite detector 102 does not send out an alarm signal, the bottom end of the push rod 443 blocks the valve body outlet 42; when the composite detector 102 sends out an alarm signal, the temperature sensing component 444 can be triggered, and the push rod 443 can be moved toward the fixing frame 441 side to open the valve body outlet 42.

[0061] In the disclosed embodiment, the fixing frame 441 is fixedly arranged on the valve body 43 and corresponds to the position of the valve body outlet 42. A clamping screw 442 is arranged on the fixing frame 441, wherein a slideway corresponding to the valve body outlet 42 is arranged on the valve body 43, and a push rod 443 is arranged in the slideway. Here, a temperature sensing component 444 is arranged between the clamping screw 442 and the push rod 443. In this way, the bottom end of the push rod 443 can block the valve body outlet 42 through the pressure of the clamping screw 442. In the case that the composite detector 102 sends out an alarm signal, the controller makes a fire determination and confirms it, and then triggers the temperature sensing component 444, which can move the push rod 443 to the side of the fixing frame 441, that is, the bottom end of the push rod 443 leaves the valve body outlet 42 to open the valve body outlet 42.

[0062] In the embodiment of the present disclosure, when the temperature sensing component 444 is triggered, the temperature sensing component 444 softens or breaks, causing the clamping screw 442 to lose the function of clamping the push rod 443, so that after the fire extinguishing agent flows into the valve channel, the pressure of the fire extinguishing agent squeezes the push rod 443 to move toward the fixing frame 441.

[0063] Combination Figure 5As shown, in some embodiments, the temperature sensing component 444 includes: an electric heating element 4441; a glass tube 4442, which is arranged between the top rod 443 and the pressing screw 442, wherein the electric heating element 4441 is arranged on the glass tube to heat the glass tube to break it.

[0064] In the embodiment of the present disclosure, the electric heating element 4441 is fixedly arranged on the fixing frame 441. When the composite detector 102 sends out an alarm signal, the electric heating element 4441 can be energized, and then the electric heating element 4441 heats the glass tube 4442, so that the glass tube 4442 breaks, thereby opening the corresponding valve body outlet 42.

[0065] In the disclosed embodiment, the temperature sensing component 444 uses an electric heating element 4441 and a glass tube 4442. Compared with the solenoid valve structure, its cost is greatly reduced, and the effect of controlling the fire extinguishing agent can also be achieved.

[0066] Optionally, the electric heating element 4441 is an electric heating belt. The electric heating belt is made of nickel-chromium alloy and can generate heat after being powered on. The electric heating belt wraps the glass tube 4442.

[0067] Optionally, the electric heating element 4441 includes a plurality of electric heating wires. The electric heating wires can be used to heat the glass tube 4442. The electric heating wire is in a wire-like structure. Specifically, the electric heating wire is wound around the glass tube 4442. By winding, the electric heating wire can be fixed to the glass tube 4442 and has more contact with the glass tube 4442, which is convenient for rapid heating.

[0068] Combination Figure 5 As shown, in some embodiments, a detection interface 421 is further provided on the side of the valve body outlet 42 for connecting a detection component to monitor the flow rate of the fire extinguishing agent at the valve body outlet 42 in real time.

[0069] In the embodiment of the present disclosure, a detection interface 421 is provided on one side of each valve body outlet 42, and the detection interface 421 can be connected to a detection component, so that the flow rate of the fire extinguishing agent at the valve body outlet 42 can be monitored through the detection component, so as to determine whether the fire extinguishing agent flows into or leaks from the valve body outlet 42. Here, when the detection interface 421 is not connected to the detection component, the detection interface 421 is blocked.

[0070] Combination Figure 2 and Figure 3 As shown, in some embodiments, when a plurality of distributing valves 40 are provided, adjacent distributing valves 40 are connected via a connecting pipe section 21 .

[0071] In the embodiment of the present disclosure, if the fire protection charging cabinet has multiple charging compartments 101, multiple distribution valves 40 may be provided to facilitate the connection of the distribution valve 40 with each charging compartment 101. In this way, not only is the distribution valve 40 more convenient, but the length of each second pipeline 61 in the second pipeline group 60 can also be effectively reduced.

[0072] Here, the two ends of the distribution valve 40 are respectively a valve body inlet 41 and a valve body outlet 42 , and adjacent distribution valves 40 are connected via a connecting pipe section 21 . Specifically, the valve body outlet 42 of a distribution valve 40 is connected to the valve body inlet 41 of an adjacent distribution valve 40 .

[0073] In some embodiments, the control valve assembly 20 also includes: a second blocking member, which is arranged at the outlet end of the fire extinguisher 10, wherein the second blocking member is used to communicate with the composite detector 102, and when the composite detector 102 sends an alarm signal, the second blocking member opens the outlet end of the fire extinguisher 10.

[0074] In the disclosed embodiment, the structure of the second blocking member is the same as that of the first blocking member 44, so that the fire extinguishing agent in the fire extinguisher 10 can be further controlled to avoid the occurrence of detection errors of the composite detector 102, which causes the fire extinguishing agent to be ejected instantly. Here, when the composite detector 102 sends an alarm signal, the second blocking member, the solenoid valve 20 and the first blocking member 44 operate simultaneously, so that the fire can be extinguished in the first time under accurate conditions to minimize the loss.

[0075] Combination Figure 7 As shown, the embodiment of the present disclosure also provides a fire protection charging cabinet, including: a cabinet body 100, in which one or more charging compartments 101 are arranged, and each charging compartment 101 is provided with a composite detector 102 and a fire extinguishing nozzle; a fire extinguishing device of the fire protection charging cabinet as described in the aforementioned embodiment, the fire extinguishing device is arranged in the cabinet body 100; wherein, the fire extinguisher 10 and the control valve assembly 20 are communicatively connected with the composite detector 102, and when the composite detector 102 sends an alarm signal, the control valve assembly 20 opens to enable the fire extinguisher 10 to extinguish the fire in the charging compartment 101.
