Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a fire-fighting device and a battery swapping station. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] In the development of battery technology, how to improve the reliability of battery swapping stations is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a fire-fighting device and a battery swapping station, which can improve the reliability of the battery swapping station.

[0005] This application is achieved through the following technical solution:

[0006] In a first aspect, this application provides a fire-fighting device for fire protection of batteries. The fire-fighting device includes a housing, a support mechanism, and a closing mechanism. The housing has an opening for the battery to enter, and the bottom of the housing forms a water reservoir. The support mechanism is disposed within the housing and above the water reservoir, and is configured to switch between a first state and a second state. In the first state, the support mechanism supports the battery; in the second state, the support mechanism releases the battery so that it falls into the water reservoir. The closing mechanism is used to close the opening after the battery enters the housing.

[0007] The technical solution of this application embodiment, by setting a support mechanism to switch between a first state and a second state, allows a thermally runaway battery to fall into a water storage tank after entering the chamber, or after thermal runaway occurs while the battery is inside the chamber, thereby providing fire protection (cooling, extinguishing, etc.) for the battery and reducing the risk of further losses (property damage, personal injury, etc.) caused by battery thermal runaway. Simultaneously, by setting a sealing mechanism to close the opening after the battery enters the chamber, fire protection of the thermally runaway battery is carried out within the chamber, reducing the risk of the battery affecting the outside and causing damage during fire protection. When the fire protection device is used in a battery swapping station, when a battery in the station experiences thermal runaway or shows a tendency to do so, the fire protection device can be used to extinguish the battery, which helps improve the reliability of the battery swapping station.

[0008] In some embodiments, the closing mechanism includes a closing door and a first drive member, the closing door being movably connected to the cabin, and the first drive member being used to drive the closing door to move in order to open or close the opening.

[0009] The technical solution of this application embodiment drives the closed door to move by setting a first driving component to open or close the opening, which facilitates the entry of the battery into the cabin while reducing the risk of the battery affecting the outside during fire fighting and saving manpower.

[0010] In some embodiments, the first driving member is used to drive the closed door to reciprocate along a first direction, which is parallel to the direction of gravity.

[0011] The technical solution of this application embodiment sets the closed door to reciprocate along a first direction, so that the closed door and the cabin share the same floor space, thereby reducing the floor area occupied by the closed door and reducing the space occupied by fire-fighting equipment.

[0012] In some embodiments, the closing mechanism further includes a first guide rail extending along a first direction and connected to the cabin body, and a first driving member for driving the closing door to move along the first guide rail.

[0013] The technical solution of this application embodiment improves the stability of the closed door movement by setting a first guide rail, which allows the closed door to move along the first guide rail.

[0014] In some embodiments, the fire suppression system further includes a smoke sensor disposed within the chamber. The support mechanism is configured to switch from a first state to a second state when the smoke sensor detects that the smoke concentration within the chamber exceeds a threshold.

[0015] The technical solution of this application embodiment detects the smoke concentration inside the chamber by setting a smoke sensor, thereby determining whether the battery has thermal runaway. The detection data of the smoke sensor switches the support mechanism from a first state to a second state, so that when the battery thermal runaway occurs, the battery can be extinguished in a more timely and accurate manner, reducing the risk of loss caused by battery thermal runaway.

[0016] In some embodiments, the fire-fighting device further includes a cleaning mechanism disposed within the compartment, which is used to clean the batteries that enter the compartment.

[0017] The technical solution of this application embodiment addresses the issue that during use or battery replacement, impurities (such as dust or large particles) can easily accumulate on the outer surface of the battery, affecting its appearance and potentially causing short circuits or assembly difficulties when the battery is installed in an electrical device. Cleaning the battery with a cleaning mechanism improves its appearance and reliability. Furthermore, in the event of thermal runaway, the cleaning mechanism can spray cleaning fluid to extinguish the fire, reducing the risk of damage caused by thermal runaway.

[0018] In some embodiments, the cleaning mechanism includes a sprayer and a first blower, the sprayer being used to spray cleaning fluid onto the battery and the first blower being used to blow air onto the battery to dry the cleaning fluid on the battery.

[0019] In the technical solution of this application embodiment, after cleaning, the surface of the battery is prone to adhere to cleaning fluid. When charging or swapping the battery after cleaning, it is prone to short circuit. By using a first blower to dry the cleaning fluid on the battery, the risk of short circuit is reduced, and the reliability of the battery is improved.

[0020] In some embodiments, the cleaning mechanism is located on the top of the chamber.

[0021] The technical solution of this application embodiment places the cleaning mechanism at the top of the chamber, so that when cleaning the battery, the cleaning fluid can clean the battery from above, and due to gravity, the cleaning fluid can flow down from the top of the battery to clean other parts of the battery, which helps to improve the cleaning effect. At the same time, placing the cleaning mechanism at the top of the chamber allows it to share the housing space with the battery, saving the floor space occupied by the cleaning mechanism and making the dimensions of the chamber smaller in the length and width directions, which helps to reduce the floor space occupied by the fire-fighting device.

[0022] In some embodiments, the cleaning mechanism further includes a water pump for delivering cleaning fluid from a water storage tank to the cleaning mechanism.

[0023] The technical solution of this application embodiment uses a water pump to transport the cleaning fluid in the water storage tank to the cleaning mechanism, so that the cleaning fluid can be recycled, reducing costs and saving resources.

[0024] In some embodiments, the cleaning mechanism further includes a filter element disposed in a water storage tank, which divides the water storage tank into a sedimentation tank and a clear water tank. The sedimentation tank is used to collect the cleaning fluid after cleaning the battery, and the water pump is used to transport the cleaning fluid in the clear water tank to the cleaning mechanism.

[0025] The technical solution of this application embodiment separates the sedimentation tank and the clear water tank through a filter element, and transports the cleaning liquid in the clear water tank to the cleaning mechanism. The cleaning liquid is filtered through the filter element, which helps to improve the cleaning effect of the cleaning liquid on the battery.

[0026] In some embodiments, a drain valve is provided at the bottom of the chamber, which is connected to a water storage tank and is used to drain the cleaning fluid in the water storage tank.

[0027] The technical solution of this application embodiment, by setting a drain valve, facilitates the drainage of liquid from the water storage tank when it is necessary to replace the liquid in the tank.

[0028] In some embodiments, the fire-fighting device further includes a sealing mechanism disposed within the chamber, the sealing mechanism being used to seal the battery connector.

[0029] In the technical solution of this application embodiment, during the battery cleaning process, the cleaning fluid may enter the battery through the battery connector (the connector can be divided into electrical connector and water-cooling connector). For example, the cleaning fluid may wet the electrical connector and the circuit connected to the electrical connector, causing a short circuit in the battery. Or, the cleaning fluid may enter the battery's water-cooling channel through the water-cooling connector and mix with the coolant, causing the coolant to dilute and affecting the battery's water-cooling effect. By sealing the battery connector through a sealing mechanism, the probability of the cleaning fluid entering the battery is reduced, thereby reducing the risk of battery short circuit, reducing the risk of affecting battery water cooling, and improving battery reliability.

[0030] In some embodiments, the sealing mechanism includes a second drive member and a seal member, the second drive member being used to drive the seal member to move so that the seal member seals or opens the battery connector.

[0031] The technical solution of this application embodiment drives the seal to move through the second driving member, which improves the convenience of sealing and opening the battery connector, saves manpower, and at the same time, drives the seal to move, which helps to shorten the distance between the seal and the battery, reduces the risk that the seal cannot seal the battery due to the large distance between the seal and the battery, and helps to improve the reliability of the battery.

[0032] In some embodiments, the second driving member is used to drive the seal to reciprocate along a first direction, which is parallel to the direction of gravity.

[0033] The technical solution of this application embodiment typically aims to reduce the footprint of the fire-fighting device by placing the seal above the battery, sharing the same space with it. A second driving member drives the seal to reciprocate along a first direction, improving the convenience of sealing and opening the battery connector.

[0034] In some embodiments, the sealing mechanism further includes a base, a second guide rail, and a bracket. The base is connected to the housing, the second guide rail and a second driving member are disposed on the base, the second guide rail extends along a first direction, the bracket slides with the second guide rail, the second driving member is used to drive the bracket to move along the second guide rail, and the sealing member is disposed on the bracket.

[0035] The technical solution of this application embodiment, by setting a second guide rail, enables the seal to move along the second guide rail with the bracket, which helps to improve the stability of the seal's movement.

[0036] In some embodiments, the seal includes a first seal and a second seal, the first seal being used to seal the electrical connector of the battery and the second seal being used to seal the water-cooling connector of the battery.

[0037] The technical solution of this application embodiment, by sealing the battery's electrical connector with a first sealing element, reduces the probability of cleaning fluid entering the electrical connector and the battery interior, thereby reducing the risk of battery short circuit. Simultaneously, by sealing the battery's water-cooling connector with a second sealing element, it reduces the risk of cleaning fluid diluting the coolant and thus degrading the water-cooling effect, thereby improving battery reliability.

[0038] In some embodiments, the sealing mechanism further includes a second blower for blowing air onto the first seal to dry the liquid on the first seal.

[0039] In the technical solution of this application embodiment, during battery cleaning, the first seal seals the battery's electrical connector. Cleaning fluid easily adheres to the first seal. When cleaning the next battery, the first seal seals the battery's electrical connector again, and the liquid adhering to the first seal easily wets the battery's electrical connector, potentially causing a short circuit. Drying the liquid on the first seal using a second blower helps reduce the risk of battery short circuits.

[0040] In some embodiments, the two bulkheads of the cabin in the second direction are openable hatches, and the second direction is perpendicular to the direction of gravity.

[0041] The technical solution of this application embodiment provides an openable hatch in the second direction of the cabin, which facilitates the maintenance of the internal structure of the fire-fighting device and the maintenance of the battery inside the fire-fighting device.

[0042] Secondly, this application provides a battery swapping station, which includes a battery compartment, a transport component, and a fire-fighting device as provided in any embodiment of the first aspect. The battery compartment is used to charge the battery. The transport component shuttles between the fire-fighting device and the battery compartment for exchanging batteries between the battery compartment and the fire-fighting device.

[0043] In some embodiments, the battery swapping station further includes a temperature sensor disposed in the battery compartment, and the transporter is configured to swap the battery from the battery compartment to a fire-fighting device when the temperature sensor detects that the temperature inside the battery compartment exceeds a threshold.

[0044] The technical solution of this application embodiment detects the temperature of the battery in the battery compartment by setting a temperature sensor, thereby determining whether the battery in the battery compartment has thermal runaway. This enables the battery in the battery compartment to be transported to the fire-fighting device for fire protection in a timely and accurate manner when the battery thermal runaway or the battery has a tendency to thermal runaway, thereby reducing the risk of loss caused by battery thermal runaway and affecting the reliability of the battery compartment.

[0045] In some embodiments, the battery swapping station further includes a third drive unit for driving the fire-fighting device to move closer to or away from the battery compartment.

[0046] The technical solution of this application embodiment uses a third driving component to drive the fire-fighting device to move closer to or away from the battery compartment. When the battery compartment and the fire-fighting device exchange batteries, the third driving component drives the fire-fighting device closer to the battery compartment, thereby shortening the movement distance of the transport component and saving energy. When the fire-fighting device is used to extinguish the batteries, the third driving component drives the fire-fighting device away from the battery compartment, reducing the risk of the fire-fighting device affecting the reliability of the battery compartment when extinguishing the batteries.

[0047] In some embodiments, the fire-fighting device and the battery compartment are arranged along a second direction, which is perpendicular to the direction of gravity. The battery swapping station also includes a third guide rail extending along the second direction, and a third drive member is used to drive the fire-fighting device to move along the third guide rail.

[0048] The technical solution of this application embodiment, by setting a third guide rail, enables the fire-fighting device to move along the third guide rail, which helps to improve the stability of the fire-fighting device's movement.

[0049] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0064] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or the second direction can represent three cases: A existing alone, A and the second direction existing simultaneously, and the second direction existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0067] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0068] The battery mentioned in the embodiments of this application can be a battery device, which may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0069] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells; as an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells into a single module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0070] In some embodiments, the battery may be a battery pack, which includes a housing and one or more individual battery cell assemblies housed within the housing.

[0071] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing by fixing the battery module in the housing.

[0072] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0073] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0074] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0075] As an example, the housing can be part of the vehicle's chassis structure. For instance, the housing's roof can be at least part of the vehicle's floor, or the housing's frame can be at least part of the vehicle's crossbeams and longitudinal beams.

[0076] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0077] The battery cell may be, but is not limited to, lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc.

[0078] The development of battery technology must take into account multiple design factors, such as energy density, cycle life, discharge capacity, charge-discharge rate and other performance parameters. In addition, as environmental conditions and / or internal battery conditions change, improving the reliability of battery swapping stations is also a key consideration.

[0079] Currently, batteries provide power to electrical devices, and these devices exchange batteries with battery swapping stations. When the battery in an electrical device has low power, the device exchanges the low-powered battery to the swapping station. The battery compartment of the swapping station charges the low-powered battery, and the swapping station exchanges a fully charged battery with more power to the device, thus providing continuous power to the device.

[0080] When batteries are located in a battery swapping station, or during the battery exchange process between the swapping station and the user device, there is a risk of thermal runaway. Battery thermal runaway may be accompanied by increased battery temperature and battery fire, which could lead to a fire at the battery swapping station or other normal batteries within the station, posing a risk of property damage and personal injury, thereby affecting the reliability of the battery swapping station.

[0081] Based on the above considerations, in order to solve the problem of battery thermal runaway and its impact on the reliability of battery swapping stations, this application provides a fire-fighting device. The fire-fighting device is used for fire suppression of batteries. The device includes a housing, a support mechanism, and a closing mechanism. The housing has an opening for the battery to enter, and the bottom of the housing forms a water storage tank. The support mechanism is located inside the housing and above the water storage tank. The support mechanism is configured to switch between a first state and a second state. In the first state, the support mechanism supports the battery; in the second state, the support mechanism releases the battery so that it falls into the water storage tank. The closing mechanism is used to close the opening after the battery enters the housing.

[0082] When fire-fighting equipment is used in battery swapping stations, it can be used to extinguish thermal runaway or the tendency for thermal runaway in the batteries, thereby improving the reliability of the battery swapping station.

[0083] The technical solutions described in this application can be used in battery swapping stations and other locations where batteries are present, for fire protection of battery cells or battery devices used by various electrical devices, such as electric vehicles, cars, ships, and spacecraft.

[0084] Please refer to Figures 2 to 4 , Figure 2 This is a schematic diagram of a fire-fighting device provided in some embodiments of this application. Figure 3 This is a schematic diagram of a battery entering a fire-fighting device according to some embodiments of this application. Figure 4 The diagram shows the structure of a fire-fighting device provided in some embodiments of this application. The diagram is intended to clearly illustrate the internal structure of the fire-fighting device. Figure 3 and Figure 4 Part of the bulkhead of the cabin is concealed. This application provides a fire-fighting device 1 for fire suppression of a battery 100. The fire-fighting device 1 includes a cabin 10, a support mechanism 20, and a closing mechanism 30. The cabin 10 has an opening 11 for the battery 100 to enter the cabin 10, and a water storage tank 12 is formed at the bottom of the cabin 10. The support mechanism 20 is disposed inside the cabin 10 and above the water storage tank 12. The support mechanism 20 is configured to switch between a first state and a second state. In the first state, the support mechanism 20 supports the battery 100; in the second state, the support mechanism 20 releases the battery 100 so that the battery 100 falls into the water storage tank 12. The closing mechanism 30 is used to close the opening 11 after the battery 100 enters the cabin 10.

[0085] In some embodiments, the fire-fighting device 1 may include a compartment 10, which may be made of metal or alloy.

[0086] In some embodiments, the housing 10 may have a cavity with an opening 11 through which the battery 100 enters and exits the cavity.

[0087] The number of openings 11 can be one, and one opening 11 is used for the battery 100 to enter the cavity.

[0088] Alternatively, there can be two openings 11, one of which is used for the battery 100 to enter the cavity, and the other is used for the battery 100 to be removed from the cavity.

[0089] In some embodiments, the opening 11 can be normally open.

[0090] In some embodiments, when the battery 100 enters the cavity, the opening 11 can be in an open state; when the battery 100 enters the cavity, the fire-fighting device 1 fires the battery 100, and the opening 11 can be closed.

[0091] In some embodiments, the opening 11 may be located above or on the side of the hull 10.

[0092] In some embodiments, the fire-fighting device 1 may include a support mechanism 20, which may be installed inside the cabin 10 to divide the space of the cabin 10 into upper and lower parts, with a water storage tank 12 located below the support mechanism 20.

[0093] The battery 100 enters the cabin 10 through the opening 11 and is supported by the support mechanism 20. The battery 100 can be statically monitored or its thermal runaway potential can be detected by sensors to determine whether fire suppression is required. When fire suppression is required, the support mechanism 20 switches from a first state to a second state, causing the battery 100 to fall into the water storage tank 12, where the liquid in the tank 12 cools or extinguishes the fire.

[0094] In some embodiments, the support mechanism 20 has a first state and a second state. In the first state, the support mechanism 20 supports the battery 100. In the second state, for example, when the battery 100 experiences thermal runaway, the temperature of the battery 100 is high, and it may be accompanied by fire or the ejection of high-temperature substances from the inside of the battery 100, such as high-temperature gas, liquid, or other solids inside the battery 100. At this time, the support mechanism 20 releases the battery 100, that is, the battery 100 loses its support and falls into the water storage tank 12, where it is submerged by the liquid in the water storage tank 12 to cool down or extinguish the fire.

[0095] It should be noted that the battery 100 can usually be transported from the opening 11 into the compartment 10 by a forklift or other transport device. The battery 100 needs to be supported by the support mechanism 20 so that the device that transports the battery 100 can detach from the battery 100 and leave the compartment 10 through the opening 11.

[0096] In some embodiments, the fire-fighting device 1 may include a sealing mechanism 30, which opens an opening 11 before the battery 100 enters the compartment 10, so that the battery 100 can enter the compartment 10 through the opening 11.

[0097] When the battery 100 enters the cabin 10, the sealing mechanism 30 can close the opening 11, thereby forming a relatively enclosed space inside the cabin 10 to reduce the impact of the thermally runaway battery 100 on the external environment of the fire-fighting device 1.

[0098] Please refer to Figure 9 and Figure 10 , Figure 9 A schematic diagram of the support mechanism provided in some embodiments of this application in a first state. Figure 10 This is a schematic diagram of a second state of the support mechanism provided in some embodiments of this application. In some embodiments, the support mechanism 20 may include a support member 21, a limiting member 22, and a fourth driving member 23. The support member 21 is rotatably connected to the cabin 10, and the fourth driving member 23 is used to drive the limiting member 22 to move between a first position that restricts the rotation of the support member 21 and a second position that allows the support member 21 to rotate.

[0099] In the first state, the limiting member 22 is in the first position and the support member 21 supports the battery 100; in the second state, the limiting member 22 is in the second position and the support member 21 releases the battery 100.

[0100] In some embodiments, the support member 21 may be a plate-like member, supporting the battery 100 below.

[0101] In some embodiments, the support mechanism 20 may include two support members 21, which are respectively supported on both sides of the battery 100 in the second direction Y.

[0102] In some embodiments, the support mechanism 20 may include a mounting base connected to the bulkhead of the hull 10. The mounting base is provided with a rotating shaft extending in a second direction Y. The support member 21 is disposed on the mounting base and cooperates with the rotating shaft. The rotating shaft has an axis extending in the second direction Y, and the rotating shaft rotates about the axis, thereby causing the support member 21 to flip.

[0103] In some embodiments, the limiting member 22 may be a block or other shape. The limiting member 22 has a first position and a second position. In the first position, the limiting member 22 may abut against the support member 21 on a third-direction X surface, thereby restricting the support member 21 from rotating about the axis of rotation, so that the support mechanism 20 is in a first state, and the support member 21 supports the battery 100.

[0104] In the second position, the limiting member 22 can move along the second direction Y, thereby separating the limiting member 22 from the support member 21. The limiting member 22 no longer abuts against the support member 21, and the support member 21 rotates and flips around the pivot, causing the battery 100 to fall into the water storage tank 12.

[0105] In some embodiments, the support mechanism 20 may include a fourth driving member 23, which may be disposed on a mounting base and may be a cylinder or a motor. The output shaft of the fourth driving member 23 may be connected to the limiting member 22, thereby driving the limiting member 22 to move along the second direction Y.

[0106] In some embodiments, the support mechanism 20 may include a guide rail, which may be disposed on a mounting base. The guide rail may extend along a second direction Y, the limiting member 22 may slide with the guide rail, and the fourth driving member 23 may drive the limiting member 22 to move along the guide rail.

[0107] In some embodiments, the support mechanism 20 may include guide members, which may be disposed around the support member 21. The guide members may have guide surfaces, which may be inclined surfaces. Each guide surface forms a cavity for accommodating the battery 100. In the first direction Z, the cavities formed by the guide surfaces gradually decrease in size from top to bottom. After the battery 100 enters the housing 10, it can move along the first direction Z towards the support member 21 until it is supported by the support member 21. During this movement, each surface of the battery 100 can contact each guide surface and move along the guide surface. When the support member 21 supports the battery 100, each guide surface contacts the surface of the battery 100. The guide surfaces guide the battery 100, allowing it to fall into a designated position and be supported by the support member 21.

[0108] In some embodiments, the battery 100 enters the housing 10 and falls onto the support member 21, at which time the limiting member 22 abuts against the support member 21, so that the support member 21 supports the battery 100.

[0109] In some embodiments, the battery 100 enters the chamber 10 and falls onto the support member 21. At this time, the limiting member 22 abuts against the support member 21 to restrict the rotation of the support member 21, so that the support member 21 supports the battery 100. When the battery 100 experiences thermal runaway, the fourth driving member 23 drives the limiting member 22 to move, causing the limiting member 22 to separate from the support member 21 and no longer restricting the rotation of the support member 21. At this time, the support member 21 flips over, causing the battery 100 to fall into the water tank 12 below to cool down the battery 100 and extinguish the fire.

[0110] In some embodiments, the support member 21 has a tendency to rotate, and in the first state, the limiting member 22 restricts the rotation of the support member 21. When the support mechanism 20 is in the second state, the support member 21 rotates to achieve a flip. In order for the support member 21 to continue supporting the next battery 100, the support member 21 can be manually flipped and the limiting member 22 can limit the support member 21, so that the support member 21 can continue to support the next battery 100.

[0111] In some embodiments, there are two support mechanisms 20, which are distributed on both sides of the cabin 10 in the third direction X. The size of the cabin 10 in the third direction X can be larger than the size of the cabin 10 in the second direction Y.

[0112] In some embodiments, the third direction X can be the length direction of the cabin 10, and the second direction Y can be the height direction of the cabin 10.

[0113] In some embodiments, two support mechanisms 20 are respectively disposed on both sides of the cabin 10 in the third direction X. When the battery 100 is supported by the support mechanism 20, the two sides of the battery 100 in the third direction X are in contact with the support mechanism 20.

[0114] The battery 100 has a quick-change lock, which is generally located on both sides of the battery 100 in the width direction. In order to make the compartment 10 compatible with the battery 100, the length direction of the compartment 10 is usually parallel to the length direction of the battery 100, the width direction of the compartment 10 is parallel to the width direction of the battery 100, and the height direction of the compartment 10 is parallel to the height direction of the battery 100.

[0115] Therefore, by placing the two support mechanisms 20 on both sides of the cabin 10 in the third direction X, the interference between the support mechanisms 20 and the quick-change lock is reduced, as well as the risk of affecting the maintenance of the quick-change lock.

[0116] The technical solution of this application embodiment, by setting a support mechanism 20 to switch between a first state and a second state, allows the thermally runaway battery 100 to fall into the water storage tank 12 after entering the cabin 10, or after thermal runaway occurs after entering the cabin 10, thereby providing fire protection (cooling, extinguishing, etc.) for the battery 100 and reducing the risk of further losses (property damage, personal injury, etc.) caused by the thermal runaway of the battery 100. Simultaneously, by setting a sealing mechanism 30 to close the opening 11 after the battery 100 enters the cabin 10, fire protection for the thermally runaway battery 100 is carried out within the cabin 10, reducing the risk of the battery 100 affecting the outside and causing damage during fire protection. When the fire-fighting device 1 is used in the battery swapping station 200, when the battery 100 in the battery swapping station 200 experiences thermal runaway or has a tendency to experience thermal runaway, the fire-fighting device 1 is used to protect the battery 100, which helps improve the reliability of the battery swapping station 200.

[0117] Please refer to Figures 2 to 4 In some embodiments, the closing mechanism 30 includes a closing door 31 and a first drive member 32. The closing door 31 is movably connected to the cabin 10, and the first drive member 32 is used to drive the closing door 31 to move in order to open or close the opening 11.

[0118] In some embodiments, the sealing mechanism 30 may include a sealing door 31. Before the battery 100 enters the compartment 10, the sealing door 31 is opened to allow the battery 100 to enter the compartment 10 through the opening 11. After the battery 100 enters the compartment 10, the sealing door 31 can be closed to seal the opening 11, thereby forming a relatively enclosed space inside the compartment 10. The battery 100 performs fire suppression within the compartment 10, and the flames, high-temperature gases, and toxic gases generated by the thermal runaway of the battery 100 are also contained within the compartment 10, thereby reducing the impact of the battery 100 on the external environment during fire suppression.

[0119] In some embodiments, the cabin 10 may be provided with a pivot, and the sealing door 31 cooperates with the pivot so that the sealing door 31 can rotate to open or close the opening 11.

[0120] In some embodiments, the sealing door 31 may be slidably connected to the cabin 10, such that the sealing door 31 may slide relative to the cabin 10 along a first direction Z, or the sealing door 31 may slide relative to the cabin 10 along a third direction X, so that the sealing door 31 may open or close the opening 11.

[0121] In some embodiments, the closing mechanism 30 may include a first driving member 32, which may be a cylinder, a motor, or the like. The output shaft of the first driving member 32 may be connected to the closing door 31, so that the first driving member 32 can drive the closing door 31 to move, thereby opening or closing the opening 11.

[0122] In some embodiments, before the battery 100 enters the compartment 10, the first drive member 32 drives the closing door 31 to move, and the closing door 31 opens so that the battery 100 can enter the compartment 10 through the opening 11. After the battery 100 enters the compartment 10, the first drive member 32 drives the closing door 31 to move, and the closing door 31 closes to seal the opening 11.

[0123] The technical solution of this application embodiment drives the closed door 31 to move by setting the first driving member 32 to open or close the opening 11, which facilitates the entry of the battery 100 into the cabin 10, while reducing the risk of the battery 100 affecting the outside during fire fighting and saving manpower.

[0124] Please refer to Figures 2 to 4In some embodiments, the first driving member 32 is used to drive the closed door 31 to reciprocate along a first direction Z, which is parallel to the direction of gravity.

[0125] In some embodiments, the first direction can be represented by the direction indicated by the letter Z in the figure.

[0126] In some embodiments, the first direction Z can be parallel to the direction of gravity, and the first direction Z can be parallel to the height direction of the cabin 10.

[0127] In some embodiments, the closed door 31 can reciprocate along the first direction Z to reduce the space occupied by the closed door 31 in the horizontal direction.

[0128] The technical solution of this application embodiment sets the closed door 31 to reciprocate along the first direction Z, so that the closed door 31 and the cabin 10 share the same space, thereby reducing the area occupied by the closed door 31 and reducing the space occupied by the fire-fighting device 1.

[0129] Please refer to Figures 2 to 4 In some embodiments, the sealing mechanism 30 further includes a first guide rail 33, which extends along a first direction Z and is connected to the cabin 10. A first drive member 32 is used to drive the sealing door 31 to move along the first guide rail 33.

[0130] In some embodiments, the first guide rail 33 may extend along the first direction Z and may be connected above the cabin 10, or the first guide rail 33 may be connected to the cabin 10 and located at the opening 11.

[0131] In some embodiments, the first driving member 32 can drive the closing door 31 to move upward along the first direction Z on the first guide rail 33 to open the opening 11; the first driving member 32 can also drive the closing door 31 to move downward along the first direction Z on the first guide rail 33 to close the opening 11.

[0132] The technical solution of this application embodiment, by setting a first guide rail 33, allows the closed door 31 to move along the first guide rail 33, which helps to improve the stability of the movement of the closed door 31.

[0133] Please refer to Figure 3 In some embodiments, the fire-fighting device 1 further includes a smoke sensor 40 disposed within the chamber 10. The support mechanism 20 is configured to switch from a first state to a second state when the smoke sensor 40 detects that the smoke concentration within the chamber 10 exceeds a threshold.

[0134] In some embodiments, the fire-fighting device 1 may include a smoke sensor 40, which may be installed inside the chamber 10 and can detect the smoke concentration inside the chamber 10. When the battery 100 experiences thermal runaway, it is usually accompanied by the generation of gas or smoke. By detecting the smoke concentration inside the chamber 10 using the smoke sensor 40, it is possible to determine whether the battery 100 has experienced thermal runaway or has a tendency to experience thermal runaway.

[0135] In some embodiments, the fire-fighting device 1 may also include a controller, with the smoke sensor 40 and the support mechanism 20 respectively connected to the controller via signal connection, such as cable connection, WiFi connection, Bluetooth connection, etc.

[0136] The detection information of the smoke sensor 40 can be transmitted to the controller, which can be a computer host. The controller determines whether the battery 100 has thermal runaway based on the detection information of the smoke sensor 40. When the smoke sensor 40 detects that the smoke concentration in the cabin 10 exceeds the set threshold, the controller controls the support mechanism 20 to switch from the first state to the second state, and the battery 100 falls into the water storage tank 12.

[0137] In some embodiments, the fire-fighting device 1 may further include a temperature sensor 230 for detecting the temperature of the battery 100, thereby determining whether the battery 100 has experienced thermal runaway.

[0138] It should be noted that when the battery 100 is determined to have experienced thermal runaway or has a tendency to do so, it enters the cabin 10 and is supported by the support mechanism 20. At this time, the state of the battery 100 can be further determined by the smoke sensor 40, thereby further determining whether the fire-fighting device 1 needs to extinguish the fire on the battery 100.

[0139] The technical solution of this application embodiment detects the smoke concentration inside the cabin 10 by setting a smoke sensor 40, thereby determining whether the battery 100 has thermal runaway. The support mechanism 20 is switched from a first state to a second state by the detection data of the smoke sensor 40, so that when the battery 100 thermally runs away, the battery 100 can be extinguished in a more timely and accurate manner, reducing the risk of loss caused by the thermal runaway of the battery 100.

[0140] Please refer to Figures 2 to 4 and refer to Figure 8 , Figure 8 This is a schematic diagram of a cleaning mechanism provided in some embodiments of this application. The diagram is provided for ease of illustrating the structure of the cleaning mechanism. Figure 8 This is a bottom view of the top wall of the cabin. In some embodiments, the fire-fighting device 1 further includes a cleaning mechanism 50, which is disposed inside the cabin 10 and is used to clean the battery 100 that enters the cabin 10.

[0141] In some embodiments, the fire-fighting device 1 may include a cleaning mechanism 50, which is capable of spraying cleaning fluid to clean the battery 100. The cleaning fluid may be sprayed under pressure so that there is a certain impact when the cleaning fluid comes into contact with the battery 100, which helps to improve the cleaning effect of the battery 100.

[0142] In some embodiments, the cleaning solution may be a mixture of water and a cleaning agent.

[0143] In some embodiments, when the cleaning mechanism 50 cleans the battery 100, the support mechanism 20 supports the battery 100, that is, the support mechanism 20 is in the first state. The cleaning fluid after cleaning the battery 100 can be collected in the water storage tank 12 at the bottom of the compartment 10, so that the water storage tank 12 has a large amount of liquid to fire the battery 100.

[0144] It should be noted that the liquid in the water storage tank 12 can be a cleaning fluid, or it can be a liquid that was originally stored in the water storage tank 12. The original liquid and the converging cleaning fluid are mixed to cool down and extinguish the fire of the battery 100.

[0145] It should be noted that after the battery 100 is cleaned, it can leave the compartment 10 through the opening 11.

[0146] In the technical solution of this application embodiment, during use or battery replacement, impurities (such as dust or large particles) are easily present on the outer surface of the battery 100, affecting its appearance and potentially causing short circuits or assembly difficulties when the battery 100 is assembled into an electrical device. Cleaning the battery 100 using the cleaning mechanism 50 improves its appearance and reliability. Furthermore, in the event of thermal runaway of the battery 100, the cleaning mechanism 50 can spray cleaning fluid to extinguish the fire, reducing the risk of damage caused by thermal runaway.

[0147] Please refer to Figure 3 In some embodiments, the cleaning mechanism 50 includes a spray member 51 and a first blower member 52. The spray member 51 is used to spray cleaning fluid onto the battery 100, and the first blower member 52 is used to blow air onto the battery 100 to dry the cleaning fluid on the battery 100.

[0148] In some embodiments, the cleaning mechanism 50 may include a spray member 51, which may be disposed on the wall of the chamber 10. The spray member 51 may be disposed inside the wall, and the surface of the wall is provided with channels for the spray member 51 to spray cleaning fluid.

[0149] In some embodiments, the spray element 51 may have a pressure pump so that the cleaning fluid can be sprayed out at a certain speed.

[0150] In some embodiments, the cleaning mechanism 50 may include a first air blower 52, which may be disposed on the wall of the chamber 10. The first air blower 52 may be a hose structure for easy stretching, with one end of the hose structure connected to the chamber wall and the other end provided with an air outlet for drying the cleaning fluid on the battery 100.

[0151] In some embodiments, the first blower 52 can blow out warm air.

[0152] In some embodiments, the battery 100 enters the chamber 10, the spray member 51 sprays out cleaning fluid to clean the battery 100, after cleaning is completed, the spray member 51 is turned off, the first blower 52 is activated to dry the cleaning fluid on the battery 100, and after drying, the battery 100 leaves the chamber 10.

[0153] In the technical solution of this application embodiment, after cleaning, the surface of the battery 100 is prone to being coated with cleaning fluid. When charging or swapping the battery 100 after cleaning, it is prone to short circuit. By setting the first blower 52 to dry the cleaning fluid on the battery 100, the risk of short circuit of the battery 100 is reduced, and the reliability of the battery 100 is improved.

[0154] Please refer to Figure 3 In some embodiments, the cleaning mechanism 50 is located on the top of the chamber 10.

[0155] In some embodiments, the cabin 10 may have multiple bulkheads, which may include a top wall, a bottom wall, and multiple side walls. The top wall and the bottom wall are disposed opposite each other in a first direction Z, with the top wall located above the bottom wall. One end of the multiple side walls is disposed around the outer perimeter of the bottom wall in the first direction Z, and the other end is connected to the top wall. The top wall, the bottom wall, and the multiple side walls form a chamber for accommodating the battery 100, and the bottom wall and the side walls form a water reservoir 12.

[0156] In some embodiments, the cleaning mechanism 50 may be disposed on the top wall of the chamber 10, that is, the spray member 51 and the first blower 52 are disposed on the top wall.

[0157] The technical solution of this application embodiment places the cleaning mechanism 50 on the top of the chamber 10, so that when cleaning the battery 100, the cleaning fluid can clean the battery 100 from above, and due to gravity, the cleaning fluid can flow down from the top of the battery 100 to clean other parts of the battery 100, which helps to improve the cleaning effect. At the same time, placing the cleaning mechanism 50 on the top of the chamber 10 allows it to share the housing space with the battery 100, saving the floor space of the cleaning mechanism 50, making the dimensions of the chamber 10 smaller in the length and width directions, which helps to reduce the floor space occupied by the fire-fighting device 1.

[0158] Please refer to Figure 4In some embodiments, the cleaning mechanism 50 further includes a water pump 53 for delivering cleaning fluid from the water tank 12 to the cleaning mechanism 50.

[0159] In some embodiments, the cleaning mechanism 50 may include a water pump 53, one end of which is connected to a water storage tank 12 and the other end is connected to a spray element 51 of the cleaning mechanism 50, so that the cleaning liquid in the water storage tank 12 can be delivered to the spray element 51 and sprayed out from the spray element 51 to clean the battery 100.

[0160] In some embodiments, the spray member 51 sprays cleaning fluid to clean the battery 100. After cleaning the battery 100, the cleaning fluid flows into the water storage tank 12 below under the action of gravity. The water pump 53 transports the cleaning fluid flowing into the water storage tank 12 to the spray member 51 to realize the recycling of the cleaning fluid.

[0161] It should be noted that the water pump 53 delivers the cleaning fluid from the water storage tank 12 to the cleaning mechanism 50. The cleaning fluid sprayed by the cleaning mechanism 50 is collected in the water storage tank 12, realizing the circulation of the cleaning fluid. During the circulation of the cleaning fluid, the liquid in the water storage tank 12 is always maintained at a set height so that the liquid in the water storage tank 12 can submerge the battery 100 when fire is carried out on the battery 100.

[0162] The technical solution of this application embodiment uses a water pump 53 to transport the cleaning liquid in the water storage tank 12 to the cleaning mechanism 50, so that the cleaning liquid can be recycled, reducing costs and saving resources.

[0163] Please refer to Figure 4 In some embodiments, the cleaning mechanism 50 further includes a filter element 54, which is disposed in the water storage tank 12 and divides the water storage tank 12 into a sedimentation tank 121 and a clear water tank 122. The sedimentation tank 121 is used to collect the cleaning fluid after cleaning the battery 100, and the water pump 53 is used to transport the cleaning fluid in the clear water tank 122 to the cleaning mechanism 50.

[0164] In some embodiments, the cleaning mechanism 50 may include a filter element 54, which may be a mesh structure to filter larger particulate impurities, thereby reducing the risk of impurities clogging the pipes of the water pump 53.

[0165] During use or battery swapping, impurities may adhere to the surface of the battery 100. After being cleaned by the cleaning mechanism 50, the battery moves to the water storage tank 12 with the cleaning fluid. The water storage tank 12 is divided into a sedimentation tank 121 and a clear water tank 122 by a filter element 54. When the cleaning fluid flows from the sedimentation tank 121 to the clear water tank 122, the filter element 54 can filter out the impurities. The water pump 53 delivers the cleaning fluid in the clear water tank 122 to the cleaning mechanism 50.

[0166] The technical solution of this application embodiment separates the sedimentation tank 121 and the clear water tank 122 through the filter element 54, and transports the cleaning liquid in the clear water tank 122 to the cleaning mechanism 50. The cleaning liquid is filtered by the filter element 54, which helps to improve the cleaning effect of the cleaning liquid on the battery 100.

[0167] Please refer to Figure 2 and Figure 3 In some embodiments, a drain valve 13 is provided at the bottom of the chamber 10. The drain valve 13 is connected to the water storage tank 12 and is used to drain the cleaning fluid in the water storage tank 12.

[0168] In some embodiments, the fire-fighting device 1 may include a drain valve 13, which is connected to the water storage tank 12. When there is too much liquid in the water storage tank 12 or the liquid in the water storage tank 12 is too turbid to be recycled for cleaning the battery 100, the liquid in the water storage tank 12 can be drained through the drain valve 13.

[0169] The technical solution of this application embodiment, by setting a drain valve 13, facilitates the drainage of liquid in the water storage tank 12 when it is necessary to replace the liquid in the water storage tank 12.

[0170] Please refer to Figure 3 In some embodiments, the fire-fighting device 1 further includes a sealing mechanism 60 disposed within the housing 10, which is used to seal the connector of the battery 100.

[0171] In some embodiments, the fire-fighting device 1 may include a sealing mechanism 60, which seals the connector of the battery 100 before cleaning, thereby reducing the risk of cleaning fluid wetting the connector when cleaning the battery 100. After cleaning the battery 100, the sealing mechanism opens the connector of the battery 100, and the battery 100 leaves the chamber 10.

[0172] In the technical solution of this application embodiment, during the cleaning process of battery 100, cleaning fluid may enter the battery 100 through the connector (the connector can be divided into electrical connector and water-cooling connector). For example, the cleaning fluid may wet the electrical connector and the circuit connected to the electrical connector, causing the battery 100 to short-circuit. For example, the cleaning fluid may enter the water-cooling channel of battery 100 through the water-cooling connector and mix with the coolant, causing the coolant to dilute and affecting the water-cooling effect of battery 100. By sealing the connector of battery 100 by the sealing mechanism 60, the probability of cleaning fluid entering the battery 100 is reduced, thereby reducing the risk of short circuit of battery 100, reducing the risk of affecting the water-cooling of battery 100, and improving the reliability of battery 100.

[0173] Please refer to Figure 3 and refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of a sealing mechanism provided in some embodiments of this application. Figure 6 This is a schematic diagram of a sealing mechanism from another perspective, provided for some embodiments of this application. In some embodiments, the sealing mechanism 60 includes a second drive member 61 and a seal member 62, the second drive member 61 being used to drive the seal member 62 to move, so that the seal member 62 seals or opens the connector of the battery 100.

[0174] In some embodiments, the second drive element 61 may be a cylinder or an electric motor.

[0175] In some embodiments, the seal 62 may be made of plastic, metal, or other materials. The seal 62 may mate with the connector of the battery 100.

[0176] In some embodiments, the second drive member 61 may include an output shaft, which may be connected to the seal 62, thereby driving the seal 62 to move in a direction closer to or away from the battery 100. After the battery 100 enters the housing 10, the second drive member 61 drives the seal 62 to move closer to the battery 100, so that the seal 62 seals the connector of the battery 100; after the battery 100 is cleaned, the second drive member 61 drives the seal 62 to move away from the battery 100, so that the seal 62 separates from the connector of the battery 100, and the battery 100 leaves the housing 10.

[0177] The technical solution of this application embodiment drives the seal 62 to move through the second driving member 61, which improves the convenience of sealing and opening the connector of the battery 100 by the seal 62 and saves manpower. At the same time, driving the seal 62 to move helps to shorten the distance between the seal 62 and the battery 100, reducing the risk that the seal 62 may not be able to seal the battery 100 due to the large distance between the seal 62 and the battery 100, and thus improving the reliability of the battery 100.

[0178] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the second driving member 61 is used to drive the seal member 62 to reciprocate along a first direction Z, which is parallel to the direction of gravity.

[0179] In some embodiments, in the first direction Z, after the battery 100 enters the housing 10, the seal 62 can be positioned above the battery 100. At this time, the second drive member 61 drives the seal 62 to move downward to seal the connector of the battery 100. After cleaning is completed, the second drive member 61 drives the seal 62 to move upward to reset, so that the seal 62 separates from the connector of the battery 100, and the battery 100 leaves the housing 10.

[0180] In this application, the technical solution typically aims to reduce the footprint of the fire-fighting device 1 by placing the sealing member 62 above the battery 100, sharing the footprint with the battery 100. The second driving member 61 drives the sealing member 62 to reciprocate along the first direction Z, which improves the convenience of sealing and opening the connector of the battery 100.

[0181] Please refer to Figure 5 and Figure 6 In some embodiments, the sealing mechanism 60 further includes a base 63, a second guide rail 64, and a bracket 65. The base 63 is connected to the housing 10. The second guide rail 64 and the second driving member 61 are disposed on the base 63. The second guide rail 64 extends along the first direction Z. The bracket 65 is slidably engaged with the second guide rail 64. The second driving member 61 is used to drive the bracket 65 to move along the second guide rail 64. The sealing member 62 is disposed on the bracket 65.

[0182] In some embodiments, the sealing mechanism 60 may include a base 63, which may be a plate and may be disposed on the bulkhead of the hull 10. For example, the base 63 may be disposed on the bulkhead of the hull 10 extending along the first direction Z.

[0183] In some embodiments, the second guide rail 64 and the second drive member 61 may be disposed on the base 63, the second guide rail 64 may extend along the first direction Z, and the bracket 65 may have a sliding portion, such as a roller, that slides with the second guide rail 64.

[0184] In some embodiments, the seal 62 may be disposed on the bracket 65, and the form of the disposed seal may be welding, bolting, integral molding, etc.

[0185] In some embodiments, after the battery 100 enters the housing 10, the second drive member 61 drives the bracket 65 to move along the first direction Z on the second guide rail 64 to approach the battery 100, thereby bringing the seal 62 close to the battery 100 and sealing the connector of the battery 100. After the battery 100 is cleaned, the second drive member 61 drives the bracket 65 to move along the first direction Z on the second guide rail 64 to move away from the battery 100, thereby moving the seal 62 away from the battery 100 and separating it from the battery 100, allowing the battery 100 to leave the housing 10.

[0186] The technical solution of this application embodiment, by setting a second guide rail 64, enables the sealing member 62 to move along the second guide rail 64 with the bracket 65, which helps to improve the stability of the movement of the sealing member 62.

[0187] Please refer to Figure 7 , Figure 7This is a schematic diagram of a seal provided in some embodiments of this application. In some embodiments, the seal 62 includes a first seal 621 and a second seal 622, the first seal 621 being used to seal the electrical connector of the battery 100, and the second seal 622 being used to seal the water-cooling connector of the battery 100.

[0188] In some embodiments, the seal 62 may include a first seal 621 and a second seal 622, which are connected together.

[0189] In some embodiments, the connectors of the battery 100 may include an electrical connector and a water-cooling connector. The electrical connector is used to electrically connect to an electrical device to provide electrical power, or to connect to the charging terminal of the battery compartment 210 to charge the battery 100. The water-cooling connector is used to connect to the water-cooling module of the electrical device to introduce coolant into the water-cooling channels inside the battery 100, as the battery 100 generates heat during charging and discharging, and the coolant is used to cool the battery 100.

[0190] In some embodiments, the first seal 621 can seal an electrical connector, typically an electrical connector having multiple probes in an electrical connection port that transmit current. The first seal 621 can have a groove that mates with the multiple probes, and the first seal 621 can seal the electrical connection port.

[0191] In some embodiments, the second seal 622 can seal the water-cooled connector, which includes an inlet and an outlet. The second seal 622 can include two parts, one part sealing the inlet and the other part sealing the outlet.

[0192] The technical solution of this application embodiment, by sealing the electrical connector of the battery 100 with the first sealing member 621, helps to reduce the probability of cleaning fluid entering the electrical connector and the interior of the battery 100, thereby reducing the risk of short circuit in the battery 100. At the same time, by sealing the water-cooling connector of the battery 100 with the second sealing member 622, it helps to reduce the risk of the cleaning fluid diluting the coolant and thus reducing the water-cooling effect, thereby improving the reliability of the battery 100.

[0193] Please refer to Figures 5 to 7 In some embodiments, the sealing mechanism 60 further includes a second blower 66 for blowing air onto the first seal 621 to dry the liquid on the first seal 621.

[0194] In some embodiments, the second blower 66 may have an air outlet that blows out airflow to dry the liquid on the first seal 621. It should be noted that the second blower 66 dries the portion of the first seal 621 used to seal the electrical connector of the battery 100.

[0195] In some embodiments, the second blower 66 may be connected to the first seal 621.

[0196] In some embodiments, the second blowing element 66 can be a hair dryer or a heater.

[0197] In the technical solution of this application embodiment, when cleaning the battery 100, the first seal 621 seals the electrical connector of the battery 100. Cleaning fluid easily adheres to the first seal 621. When cleaning the next battery 100, the liquid adhering to the first seal 621 can easily wet the electrical connector of the battery 100, causing a short circuit in the battery 100. Drying the liquid on the first seal 621 using the second blower 66 helps reduce the risk of a short circuit in the battery 100.

[0198] Please refer to Figure 2 In some embodiments, the two bulkheads of the cabin 10 in the second direction Y are openable hatches 14, and the second direction Y is perpendicular to the direction of gravity.

[0199] In some embodiments, the second direction can be represented by the direction described by the letter X in the figure.

[0200] In some embodiments, the second direction Y may be parallel to the width direction of the hull 10.

[0201] In some embodiments, the housing 10 may have an opening 11 on one side in the third direction X, the opening 11 being used to allow the battery 100 to enter the housing 10.

[0202] In order to facilitate the maintenance of the internal structure of the cabin 10, as well as the maintenance of the battery 100 inside the cabin 10, or to remove the battery 100 after fire, without affecting the opening 11, the two bulkheads of the cabin 10 in the second direction Y can be used as openable hatches 14.

[0203] In some embodiments, the hatch 14 is closed when cleaning or fire-fighting the battery 100. The hatch 14 is opened when it is necessary to maintain the fire-fighting device 1 or maintain the battery 100.

[0204] The technical solution of this application embodiment provides an openable hatch 14 in the second direction Y of the cabin 10, which facilitates the maintenance of the internal structure of the fire-fighting device 1 and the maintenance of the battery 100 inside the fire-fighting device 1.

[0205] Please refer to Figure 1 , Figure 1This is a schematic diagram of a battery swapping station provided in some embodiments of this application. Embodiments of this application provide a battery swapping station 200, which includes a battery compartment 210, a transport component 220, and a fire-fighting device 1 as provided in any of the above embodiments. The battery compartment 210 is used to charge a battery 100. The transport component 220 shuttles between the fire-fighting device 1 and the battery compartment 210 for exchanging batteries 100 between the battery compartment 210 and the fire-fighting device 1.

[0206] In some embodiments, when the battery 100 in the battery compartment 210 experiences thermal runaway, the battery 100 in the battery compartment 210 can be transported to the fire-fighting device 1 via the transporter 220 for fire-fighting.

[0207] Alternatively, if the battery 100 in the battery compartment 210 exhibits a tendency for thermal runaway, the battery 100 in the battery compartment 210 can be transported to the fire-fighting device 1 via the transporter 220 for testing. If it is confirmed that the battery 100 exhibits a tendency for thermal runaway, fire-fighting measures are taken against the battery 100. If it is confirmed that the battery 100 does not exhibit a tendency for thermal runaway, the battery 100 in the fire-fighting device 1 is transported to the battery compartment 210.

[0208] In some embodiments, the battery compartment 210 may be provided with a compartment for charging the battery 100. An external power device exchanges a low-charged battery 100 to the battery swapping station 200, charges the low-charged battery 100 through the battery compartment 210, and exchanges a fully charged battery 100 with a larger charge in the battery compartment 210 to the power device.

[0209] In some embodiments, before the depleted battery 100 is placed into the battery compartment 210, it can be cleaned by the fire-fighting device 1 and then placed into the battery compartment 210 for charging.

[0210] In some embodiments, before a fully charged battery 100 is switched to an electrical device, the fully charged battery 100 can be cleaned by the fire-fighting device 1 before being switched to the electrical device.

[0211] In some embodiments, the transport component 220 may be a transport trolley or forklift, which transfers the batteries 100 in the battery compartment 210 to the fire-fighting device 1 for fire suppression or cleaning of the batteries 100, or transfers the cleaned batteries 100 from the fire-fighting device 1 to the battery compartment 210. The battery swapping station 200 may include a guide rail connecting the battery compartment 210 and the fire-fighting device 1, on which the transport component 220 moves.

[0212] In some embodiments, the battery compartment 210 has an entrance and exit for the battery 100 to enter and exit, and the opening 11 of the compartment 10 for the battery 100 to enter and exit and the entrance and exit of the battery compartment 210 may be located on the same side in the third direction X.

[0213] In some embodiments, the third direction can be represented by the direction indicated by the letter Y in the figure.

[0214] In some embodiments, the third direction X can be parallel to the length direction of the cabin 10.

[0215] Please refer to Figure 1 In some embodiments, the battery swapping station 200 further includes a temperature sensor 230 disposed in the battery compartment 210, and the transport component 220 is configured to swap the battery 100 from the battery compartment 210 to the fire-fighting device 1 when the temperature sensor 230 detects that the temperature inside the battery compartment 210 exceeds a threshold.

[0216] In some embodiments, the battery swapping station 200 may include a temperature sensor 230, which may be disposed within the battery compartment 210. The temperature sensor 230 is capable of detecting the temperature of the battery 100 within the battery compartment 210. When the battery 100 experiences thermal runaway or has a tendency to experience thermal runaway, it is usually accompanied by an increase in temperature. By detecting the temperature of the battery 100 within the battery compartment 210 using the temperature sensor 230, it is possible to determine whether the battery 100 has experienced thermal runaway or has a tendency to experience thermal runaway.

[0217] In some embodiments, the battery swapping station 200 may also include a controller, and the temperature sensor 230 and the transport component 220 are respectively connected to the controller via signal connection, such as cable connection, WiFi connection, Bluetooth connection, etc.

[0218] The detection information of temperature sensor 230 can be transmitted to the controller, which can be a computer host. The controller determines whether the battery 100 has thermal runaway based on the detection information of temperature sensor 230. When temperature sensor 230 detects that the temperature of battery 100 in battery compartment 210 exceeds the set threshold, the controller controls transport component 220 to transport battery 100 in battery compartment 210 to fire-fighting device 1 for fire protection of battery 100.

[0219] In some embodiments, the fire-fighting device 1 may further include a temperature sensor 230 for detecting the temperature of the battery 100, thereby determining whether the battery 100 has experienced thermal runaway.

[0220] It should be noted that when the battery 100 is determined to have experienced thermal runaway or has a tendency to do so, it enters the cabin 10 and is supported by the support mechanism 20. At this time, the state of the battery 100 can be further determined by the smoke sensor 40, thereby further determining whether the fire-fighting device 1 needs to extinguish the fire on the battery 100.

[0221] The technical solution of this application embodiment detects the temperature of the battery 100 in the battery compartment 210 by setting a temperature sensor 230, thereby determining whether the battery 100 in the battery compartment 210 has thermal runaway. This allows the battery 100 in the battery compartment 210 to be transported to the fire-fighting device 1 for fire fighting in a timely and accurate manner when the battery 100 thermally runs away or shows a tendency to thermally run away, thereby reducing the risk of loss caused by thermal runaway of the battery 100 and affecting the reliability of the battery compartment 210.

[0222] Please refer to Figure 1 In some embodiments, the battery swapping station 200 further includes a third drive unit 240 for driving the fire-fighting device 1 to move closer to or away from the battery compartment 210.

[0223] In some embodiments, the battery swapping station 200 may include a third drive unit 240, which may be a cylinder, a motor, or the like. The output shaft of the third drive unit 240 may be connected to the fire-fighting device 1 to drive the fire-fighting device 1 to move closer to or away from the battery compartment 210.

[0224] In some embodiments, when the battery compartment 210 and the fire-fighting device 1 exchange batteries 100, the third driving member 240 drives the fire-fighting device 1 to move closer to the battery compartment 210, so that the fire-fighting device 1 comes into contact with or is close to the battery compartment 210, thereby shortening the moving distance of the transport component 220 and reducing the distance of the guide rail used to support the movement of the transport component 220, thus saving costs.

[0225] In some embodiments, when the fire-fighting device 1 needs maintenance or the battery 100 in the fire-fighting device 1 needs maintenance or the battery 100 in the fire-fighting device 1 needs to be removed, the third drive member 240 can drive the fire-fighting device 1 to move away from the battery compartment 210, providing sufficient space to open the hatch 14 of the fire-fighting device 1.

[0226] At this time, the third drive unit 240 can drive the fire-fighting device 1 to move away from the battery compartment 210 to reduce the damage to the battery compartment 210 caused by thermal runaway of the battery 100.

[0227] The technical solution of this application embodiment uses a third driving component 240 to drive the fire-fighting device 1 to move closer to or away from the battery compartment 210. When the battery compartment 210 and the fire-fighting device 1 exchange batteries 100, the third driving component 240 drives the fire-fighting device 1 closer to the battery compartment 210, thereby shortening the travel distance of the transport component 220 and saving energy. When the fire-fighting device 1 is extinguishing the battery 100, the third driving component 240 drives the fire-fighting device 1 away from the battery compartment 210, reducing the risk of the fire-fighting device 1 affecting the reliability of the battery compartment 210 when extinguishing the battery 100.

[0228] Please refer to Figure 1In some embodiments, the fire-fighting device 1 and the battery compartment 210 are arranged along the second direction Y, which is perpendicular to the direction of gravity. The battery swapping station 200 also includes a third guide rail 250 extending along the second direction Y, and a third drive member 240 is used to drive the fire-fighting device 1 to move along the third guide rail 250.

[0229] In some embodiments, the battery swapping station 200 may include a third guide rail 250, and a pulley may be provided below the fire-fighting device 1. The pulley slides in cooperation with the third guide rail 250, so that the third driving member 240 can drive the fire-fighting device 1 to move along the second direction Y on the third guide rail 250.

[0230] The technical solution of this application embodiment, by setting a third guide rail 250, enables the fire-fighting device 1 to move along the third guide rail 250, which helps to improve the stability of the movement of the fire-fighting device 1.

[0231] Please refer to Figures 1 to 4 In some embodiments, the battery swapping station 200 may include a battery compartment 210, a transport component 220, and a fire-fighting device 1. The battery compartment 210 is used to charge the battery 100. A depleted battery 100 with a low charge in the power-consuming device can be transferred to the battery compartment 210, and a fully charged battery 100 with a high charge in the battery compartment 210 can be transferred to the power-consuming device.

[0232] The depleted battery 100 can be cleaned by the fire-fighting device 1 before entering the battery compartment 210, or the fully charged battery 100 can be cleaned by the fire-fighting device 1 before being transferred to the power-consuming device.

[0233] In some embodiments, the fire-fighting device 1 may include a compartment 10, with a water storage tank 12 formed at the bottom of the compartment 10. When the battery 100 in the battery compartment 210 experiences thermal runaway or has a tendency to thermal runaway, the transport component 220 transports the battery 100 in the battery compartment 210 to the compartment 10 to extinguish the fire.

[0234] When the battery 100 in the battery swapping station 200 experiences thermal runaway or shows a tendency to do so, the battery 100 is extinguished by the fire-fighting device 1, which helps to improve the reliability of the battery swapping station 200.

[0235] In some embodiments, the housing 10 is provided with an opening 11 for the battery 100 to enter the housing 10. The fire-fighting device 1 also includes a closing door 31, which opens the opening 11 before the battery 100 enters the housing 10, and closes the opening 11 after the battery 100 enters the housing 10.

[0236] By setting a closed door 31 to close the opening 11 after the battery 100 enters the cabin 10, the thermally runaway battery 100 can be extinguished inside the cabin 10, reducing the risk of the battery 100 affecting the outside and causing damage during the extinguishing process.

[0237] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
