[0002] Rechargeable batteries can be used in various fields. Rechargeable batteries can be placed in charging cabinets and other charging devices for charging. For example, in the field of drones, batteries of drones with insufficient power can be charged in charging cabinets without shutting down for charging, thereby increasing the utilization rate of drones. For example, drones in the delivery field can use this method of replacing rechargeable batteries because of the large demand for delivery items.

[0003] In related scenarios, outdoor charging cabinets can be set up to charge replaced drone lithium batteries, but during the charging and storage process, lithium batteries are at risk of thermal runaway, causing the charging cabinet to catch fire, so the charging cabinet needs to be equipped with firefighting facilities to control the fire in time and prevent the fire from spreading. Inert gas or dry powder fire extinguishers are used as the main means of firefighting, but for lithium batteries, oxygen will be released after the battery cell catches fire, which will fuel the fire. If the temperature cannot be quickly reduced after a high-temperature fire, not only will the fire control be more difficult, but there is also the possibility of a secondary fire.

[0066] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0067] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0068] Figure 1 This is a flow chart of a fire-fighting method of a charging cabinet according to an embodiment of the present disclosure, which can be applied to a charging cabinet for a lithium battery of a drone, wherein the charging cabinet can be used in conjunction with an auxiliary cabinet, and an auxiliary cabinet can be used in conjunction with one or more charging cabinets, see Figure 2 As shown, multiple charging cabinets can share a set of fire protection system 3, the charging cabinet includes a main body 1 and a battery compartment 2, the main body 1 is constructed with a battery compartment 2, the battery compartment 2 is used to store rechargeable batteries and charge the stored rechargeable batteries, the battery compartment 2 has a compartment opening 21 for the rechargeable batteries to enter and exit, the fire protection system 3 includes: an internal water fire protection pipeline 31 and an external water fire protection pipeline 32, the internal water fire protection pipeline 31 is provided with an internal water outlet nozzle 311, the external water fire protection pipeline 32 is provided with an external water outlet nozzle 321, the internal water outlet nozzle 311 points to the inside of the battery compartment 2, and the external water outlet nozzle 321 points to the outside of the compartment opening 21; and a water supply module, the water supply module is connected to the internal water fire protection pipeline 31 and the external water fire protection pipeline 32 respectively, see Figure 1 The fire protection method of the charging cabinet shown includes:

[0069] In step S11, environmental information is sensed by a sensing element deployed on the charging cabinet.

[0070] In the embodiments of the present disclosure, see Figure 3As shown, multiple sensing elements can be arranged on each charging cabinet, and each battery compartment of the charging cabinet is provided with a corresponding sensing element. For example, three temperature-sensing automatic nozzles are configured in each battery compartment of the charging cabinet. Among them, environmental information specifically refers to smoke information and temperature information around the charging cabinet or inside the battery compartment. For example, temperature information can be sensed by infrared or ultraviolet sensors.

[0071] In step S12, when the environmental information indicates that the ambient temperature is higher than the trigger temperature of the sensing element, the electromagnetic switch valve deployed in the fire protection pipeline of the charging cabinet is triggered by the sensing element.

[0072] In the disclosed embodiment, the sensing element can sense the ambient temperature of the battery compartment opening or the interior of the battery compartment, and then trigger the electromagnetic switch valve to open when the ambient temperature is higher than the trigger temperature of the sensing element, wherein the electromagnetic switch valve is arranged on the fire-fighting pipeline from the water supply module to the water outlet nozzle 311. The fire-fighting pipeline here can be the internal water fire-fighting pipeline 31 and the external water fire-fighting pipeline 32. When the electromagnetic switch valve is in the closed state, the water supply module cannot provide water to the water outlet nozzle 311, and when the electromagnetic switch valve is in the open state, the water supply module can provide water to the water outlet nozzle 311.

[0073] In the embodiment of the present disclosure, the sensing element can send environmental information to the control unit of the outdoor unit when sensing environmental information, and report the information triggering the fire-fighting action when the fire-fighting action is triggered. The auxiliary cabinet can determine the target sensing element for performing the fire-fighting action based on the sensing element that sends the information.

[0074] In step S13, when the electromagnetic switch valve is triggered, the circuit of the fire-fighting pipeline where the electromagnetic switch valve is located is turned on to trigger the fire-fighting action, and the charging circuit of the charging cabinet is cut off and the fire-fighting alarm of the charging cabinet is executed.

[0075] It is understandable that there is a corresponding relationship between the sensing element and the battery compartment, and the target battery compartment where the fire occurs can be determined according to the target sensing element that performs the fire extinguishing action. The sensing element only triggers the electromagnetic switch valve corresponding to the same battery compartment, and when the electromagnetic switch valve corresponding to the target battery compartment is triggered, the circuit of the fire protection pipeline where the electromagnetic switch valve is located is turned on, and then the fire extinguishing action is performed on the battery compartment where the sensing element is set.

[0076] The charging circuit is used to charge the lithium battery of the drone stored in the battery compartment. Figure 3 as well as Figure 4As shown, each charging cabinet is electrically connected to the shunt release in the auxiliary cabinet through an air switch and / or leakage protection switch. The shunt release is configured in the power module of the auxiliary cabinet and can provide 220V power to the charging cabinet. When any battery compartment triggers a fire extinguishing action, the electrical connection between the charging circuit of the battery compartment and the shunt release can be disconnected through the air switch and / or leakage protection switch corresponding to the charging cabinet where the battery compartment is located, thereby cutting off the charging circuit of each battery compartment in the charging cabinet. In particular, when the auxiliary cabinet is matched with multiple charging cabinets, when any battery compartment triggers a fire extinguishing action, the electrical connection between each charging cabinet and the auxiliary cabinet can be disconnected through the air switch and / or leakage protection switch corresponding to each charging cabinet.

[0077] Among them, the fire fighting alarm can be alarmed by sound and light, see Figure 3 As shown, when the target battery compartment triggers a fire extinguishing action, the sound and light alarm unit configured on the auxiliary cabinet can be triggered to alarm through sound and light signals. Figure 3 as well as Figure 4 As shown, the sound and light alarm unit can be configured with a temperature display digital tube, a smoke sensor and a water immersion sensor, an alarm light and a buzzer. Among them, the temperature display digital tube can display the ambient temperature in each battery compartment and / or the core temperature of the lithium battery in the battery compartment, the smoke sensor can be used to obtain the ambient smoke signal in the sound and light alarm unit, the water immersion sensor can be used to obtain the water immersion signal in the sound and light alarm unit, the alarm light is used for optical alarm, and the buzzer is used for sound alarm.

[0078] The "direction" used in the present disclosure refers to the direction in which the fire water can be sprayed from the internal water nozzle 311 and the external water nozzle 321 to the target area. Spraying the inside of the battery compartment 2 can extinguish or cool down the fire inside the battery, and spraying the outside of the hatch 21 of the battery compartment 2 can extinguish or cool down the fire hazard that occurs at the hatch 21. In some embodiments, because the exposed part of the rechargeable battery during charging is usually an area such as a cover plate with many components, this area is prone to fire hazards first, so a separate external water nozzle 321 pointing to the outside of the hatch 21 has a high degree of pertinence.

[0079] Specifically, when a battery experiences thermal runaway and its temperature rises, the inner water nozzle 311 and the outer water nozzle 321 can spray the inside of the battery compartment 2 and the outside of the compartment opening 21 in a targeted manner according to the specific location where the battery heats up. That is, the inner water nozzle 311 and the outer water nozzle 321 can controllably act individually or jointly on the temperature-rising location of the battery in thermal runaway to spray and cool it down in a targeted manner, so that the battery in thermal runaway can be cooled down quickly and with good fire-fighting effect.

[0080] The above technical solution senses environmental information through the sensing element deployed on the charging cabinet; when the environmental information indicates that the ambient temperature is higher than the triggering temperature of the sensing element, the sensing element triggers the electromagnetic switch valve deployed in the fire protection pipeline of the charging cabinet; when the electromagnetic switch valve is triggered, the circuit of the fire protection pipeline where the electromagnetic switch valve is located is turned on to trigger the fire fighting action, and cut off the charging circuit of the charging cabinet and execute the fire fighting alarm of the charging cabinet. After thermal runaway occurs, the fire fighting action is triggered by the sensing element, which can extinguish the fire in the first time, reduce losses, and prevent the fire from spreading. Cutting off the charging circuit of the charging cabinet can avoid the loss of the charging circuit causing a circuit short circuit, which can reduce personal injury. The fire fighting alarm can detect the fire in time. The effect of fire fighting is improved.

[0081] Optionally, the sensing element includes a thermistor, and when the environmental information indicates that the ambient temperature is higher than the triggering temperature of the sensing element, the electromagnetic switch valve deployed in the fire protection pipeline of the charging cabinet is triggered by the sensing element, including:

[0082] When the environmental information indicates that the environmental temperature is higher than the thermistor temperature of the thermistor line, a fire trigger signal is sent to the electromagnetic switch valve connected to the thermistor line through the thermistor line.

[0083] The thermistor wire can be electrically connected to the electromagnetic switch valve, for example, the thermistor wire set in the same battery compartment is electrically connected to the electromagnetic switch valve. Furthermore, when the ambient temperature is higher than the thermistor temperature of the thermistor wire, the thermistor wire can send a fire trigger signal to the corresponding electromagnetic switch valve.

[0084] When the electromagnetic switch valve is triggered, the circuit of the fire protection pipeline where the electromagnetic switch valve is located is turned on to trigger the fire extinguishing action, including:

[0085] When receiving the fire-fighting trigger signal, the electromagnetic switch valve switches on the circuit of the fire-fighting pipeline where the electromagnetic switch valve is located, so that the pipeline sprinkler configured on the fire-fighting pipeline performs a spraying action.

[0086] In one embodiment, the electromagnetic switch valve can be linked to the water pump of the water supply module, and then when the electromagnetic switch valve is triggered and opened, the water pump of the water supply module is started. The water pump can pump the water stored in the water supply module to the water outlet nozzle corresponding to the sensing element to perform a spraying action.

[0087] Among them, multiple pipe nozzles can be arranged in one battery compartment, for example, 6 pipe nozzles can be arranged in one battery compartment.

[0088] The above technical solution can be linked to execute fire fighting and extinguishing, supplying water in the water supply module to the water outlet nozzle to execute fire fighting and extinguishing action. In this way, the fire can be extinguished in the first time, the loss can be reduced, and the fire can be prevented from expanding.

[0089] Optionally, the thermistor wire is arranged in a serpentine shape inside the battery compartment and / or at a compartment opening of the battery compartment and is electrically connected to the electromagnetic switch valve.

[0090] In one example, the thermistor wire is arranged in a serpentine shape inside the battery compartment, and is electrically connected to the electromagnetic switch valve. This can save space and avoid the charging cabinet being too large compared to arranging the blasting nozzle inside the battery compartment. The pipe nozzle arranged inside the charging cabinet sprays water to perform the spraying action, which is beneficial to cool the rechargeable battery and avoid igniting the rechargeable battery.

[0091] Optionally, the sensing element includes an explosion nozzle, and when the environmental information indicates that the ambient temperature is higher than the triggering temperature of the sensing element, the electromagnetic switch valve deployed in the fire protection pipeline of the charging cabinet is triggered by the sensing element, including:

[0092] In the case where the environmental information indicates that the environmental temperature is higher than the explosion temperature of the explosion nozzle, the explosion nozzle explodes to make the water flow in the fire-fighting pipeline where the explosion nozzle is located flow.

[0093] The water flow sensor arranged in the fire-fighting pipeline senses the flow signal of the water flow and transmits the flow signal to the electromagnetic switch valve.

[0094] The water flow sensor arranged in the pipeline senses the flow signal of the water flow and transmits the flow signal to the electromagnetic switch valve.

[0095] Similarly, after the water flow sensor senses the flow signal of the water flow, it transmits the flow signal to the electromagnetic switch valve installed in the same battery compartment as the blasting nozzle. In this way, fire water can be provided to the battery compartment where the fire extinguishing action is present, while other battery compartments will not be affected.

[0096] In one embodiment, the flow signal of the water flow sensor can also be reported to the auxiliary cabinet or the cloud, so that the presence of fire extinguishing action in the charging cabinet can be determined based on the flow signal. For example, when only the flow signal is received, it can be checked whether there is a fire extinguishing action. If there is no fire extinguishing action, it can be determined that there is a water leak in the fire protection pipeline, so that the associated water leak can be repaired in time.

[0097] When the electromagnetic switch valve is triggered, the circuit of the fire protection pipeline where the electromagnetic switch valve is located is turned on to trigger the fire extinguishing action, including:

[0098] The electromagnetic switch valve conducts the circuit of the fire-fighting pipeline where the electromagnetic switch valve is located based on the flow signal, and starts the water pump connected to the fire-fighting pipeline.

[0099] In the disclosed embodiment, the water pump is the only one provided in the water supply module, that is, when any electromagnetic switch valve is opened and the pipeline in which it is located is connected, the water pump will execute the starting action.

[0100] The water pump continuously supplies fire water to the blasting sprinkler head so that the blasting sprinkler head performs a spraying action.

[0101] In the disclosed embodiment, when any battery compartment performs a fire extinguishing action, the sensing elements of other battery compartments continue to be in a sensing state. If the corresponding sensing elements of other battery compartments are triggered, the other battery compartments can also perform a fire extinguishing action.

[0102] Optionally, the blasting nozzle is deployed on the internal water fire fighting pipeline and / or the external water fire fighting pipeline of the charging cabinet.

[0103] In the disclosed embodiment, the internal water fire-fighting pipeline 31 is provided with an internal water outlet nozzle 311, which points to the interior of the battery compartment 2 and is used to spray the space and batteries inside the battery compartment, while the external water fire-fighting pipeline 32 is provided with an external water outlet nozzle 321, which points to the outside of the compartment opening 21 and is used to spray the handle of the lithium battery.

[0104] In one example, the blasting nozzle is deployed on the external water fire-fighting pipeline of the charging cabinet, and the electromagnetic switch valve connected to the thermistor can be set on the internal water fire-fighting pipeline. In this way, the thermistor is set inside the battery compartment, which can save space and avoid the charging cabinet from being too large. The blasting nozzle is arranged on the external water fire-fighting pipeline to achieve precise spraying of the compartment opening of the battery compartment.

[0105] In one embodiment, because a fire in a battery compartment usually originates from the handle of the charging battery, the thermistor temperature of the thermistor wire can be set to be higher than the blasting temperature of the blasting nozzle. For example, the thermistor temperature of the thermistor wire is 170 degrees Celsius, and the blasting temperature of the blasting nozzle is 68 degrees Celsius. Therefore, when a fire occurs first at the handle, the blasting nozzle with a low-temperature blasting can be used to perform firefighting extinguishing action first. When the fire spreads, the internal temperature of the battery compartment will rise, and the firefighting action will be performed later through the thermistor wire with a higher temperature, thereby improving the firefighting effect of the charging cabinet.

[0106] Optionally, the fire water is stored in a water tank of the charging cabinet, and the method further includes:

[0107] Obtaining the fire water level collected by a level sensor disposed in the water storage tank, wherein the water storage tank is connected to a fire water collection tray via a return pipe, and the battery compartment is installed in the fire water collection tray;

[0108] When the fire water liquid level reaches the liquid level alarm threshold, a liquid level alarm is executed.

[0109] In the embodiments of the present disclosure, see Figure 2 As shown, the fire water sprayed on the battery compartment can be collected by the fire water collection tray 39, and then flow back to the water storage tank 33 through the return pipe. The water storage tank 33 can be set in the water supply module. In addition, since the fire water sprayed on the battery compartment may contain residues, a filter can be set in the return pipe. The filter can filter the residues in the fire water to avoid clogging the pipe. In this way, the fire water can be reused, which can reduce the risk of fire fighting due to lack of water.

[0110] The method further comprises:

[0111] The information representing the flow signal is uploaded to the cloud, so that the cloud sends the information to the terminal device that meets the conditions to issue an alarm.

[0112] In the embodiment of the present disclosure, when the fire water level reaches the level alarm threshold, a level alarm signal can be sent to the subsidiary cabinet, and then the subsidiary cabinet performs a level alarm prompt, for example, by sound and light alarm. The level alarm signal can also be sent to the cloud, and the cloud sends the level alarm signal to the terminal device that meets the conditions for alarm.

[0113] Optionally, executing the fire extinguishing alarm of the charging cabinet includes:

[0114] The fire extinguishing alarm is uploaded to the cloud, so that the cloud sends the fire extinguishing alarm to the terminal device that meets the conditions for alarming.

[0115] In the embodiment of the present disclosure, the terminal device that meets the conditions may be within a preset range of the charging cabinet, and the terminal device may be a terminal walkie-talkie, a mobile phone, a tablet computer and other devices.

[0116] The fire extinguishing alarm is issued by an alarm device configured on an auxiliary cabinet connected to the charging cabinet, and the auxiliary cabinet is used to accommodate the charging cabinet.

[0117] In the disclosed embodiment, a fire extinguishing alarm may also be issued through the sound and light alarm unit on the auxiliary cabinet.

[0118] Optionally, the sensing element includes a smoke sensor; wherein the smoke sensor is arranged inside the battery compartment and / or at the compartment opening of the battery compartment.

[0119] The method further comprises:

[0120] When the environmental information indicates that the smoke concentration exceeds a smoke threshold of the smoke sensor, a smoke alarm is executed.

[0121] In a possible implementation, when the environmental information indicates that the smoke concentration exceeds the smoke threshold of the smoke sensor, the smoke sensor can send a smoke alarm signal to the auxiliary cabinet, thereby linking the auxiliary cabinet to issue a smoke alarm. At the same time, the cloud can be linked to issue an alarm, and the cloud can send the smoke alarm to the terminal device that meets the conditions for alarm.

[0122] The above technical solution can sense and trigger the smoke alarm through the smoke sensor, which can improve the comprehensiveness of perception compared to sensing only through the thermal wire and the blasting nozzle. In the case of only smoke but the temperature is not high enough to trigger the fire extinguishing action, the smoke alarm can be triggered immediately. Then, when the temperature reaches the triggering fire extinguishing action, the corresponding water spraying operation is performed.

[0123] See also Figure 5 As shown, the embodiments of the present disclosure are explained by examples. When a fire occurs in the charging cabinet, the smoke sensor can sense the smoke, thereby issuing a smoke sensor alarm, and then the auxiliary cabinet can control the disconnection of the charging circuit of the corresponding charging cabinet and control other battery compartments to maintain monitoring. The smoke alarm can be uploaded to the cloud, and the cloud can alert the target terminal through a phone call or text message, wherein the target terminal can be a pre-bound terminal or a terminal within the preset range of the charging cabinet. At the same time, the cloud can also alert the terminals of on-site personnel and the auxiliary cabinets.

[0124] The ambient temperature can trigger the thermistor to alarm, and then the auxiliary cabinet can control the disconnection of the charging circuit of the corresponding battery compartment and control other battery compartments to maintain monitoring. The thermistor triggers the alarm to open the electromagnetic switch valve, and at the same time, the electromagnetic switch valve opens to start the linkage water pump. After the water pump starts, the corresponding single battery compartment pipe nozzle sprays fire water. The fire water collected by the fire water collection tray where the charging cabinet is located flows back to the water storage tank through the return pipe. The return pipe is equipped with a filter to filter the fire water before returning to the water storage tank. A liquid level sensor is provided in the water storage tank to detect the fire water level in the water storage tank, and when the fire water level is lower than the liquid level alarm threshold, a liquid level alarm signal is generated, and then the liquid level alarm signal is uploaded to the cloud, so that the cloud can alarm the liquid level information to the target terminal through a phone call or text message, and the cloud can also alarm the liquid level information to the terminal and auxiliary cabinet of the on-site personnel.

[0125] The ambient temperature can cause the blasting nozzle to explode, so that the blasting nozzle can sound an alarm, and then the auxiliary cabinet can control the disconnection of the charging circuit of the corresponding battery compartment and control other battery compartments to maintain monitoring. After the blasting nozzle explodes, it will spray fire water. The fire water collected by the fire water collection tray where the charging cabinet is located will also flow back to the water storage tank through the return pipe. At the same time, after the blasting nozzle explodes and sprays fire water, the water flow sensor installed in the pipeline senses the flow signal of the water flow, and the flow signal is sent to the electromagnetic switch valve. The electromagnetic switch valve opens and the linkage water pump starts, and the flow signal can be uploaded to the cloud.
