It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the electric control valve in the specification is described in combination with an electric stop valve, it is obvious that other electric control valves, such as solenoid valves, electric butterfly valves or electric ball valves, can be used in the present application.

[0081] It should be noted that, in the description of this application, unless otherwise clearly specified and limited, the terms "set", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. It should be understood that the orientation or positional relationship indicated by the terms "upper" and "inner" is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, "multiple" in this application means at least two.

[0082] like Figure 1-9 As shown, in order to solve the problem that the existing water tank solution relies on the low reliability of the mechanism of the entire battery transport link of the battery swap station and there is a risk of failure, the utility model provides a battery compartment for a charging and swap station, including a battery rack 1, a retaining mechanism 7, a transfer mechanism 2, a spray mechanism and a fire box 3 that can accommodate batteries 11. The fire box 3 is arranged on the battery rack 1, the retaining mechanism 7 is arranged on the battery rack 1 and is located above the fire box 3, and the retaining mechanism 7 is arranged to be able to carry the battery 11 so that the battery 11 is switched between a retaining state in which the battery 11 is suspended above the fire box 3 and a disengaged state in which the battery 11 is released so that the battery 11 falls into the fire box 3. The transfer mechanism 2 is movably arranged on one side of the battery rack 1, and the transfer mechanism 2 is arranged to be able to transfer the battery 11 on the battery rack 1 or to transport the battery 11 to the battery rack 1. The spray mechanism includes a spray pipeline, a first spray part and a second spray part. The spray pipeline is connected to the first spray part and the second spray part. The first spray part is configured to spray the batteries 11 on the battery rack 1, and the second spray part is configured to spray the area where the transfer mechanism 2 is located.

[0083] In this way, when the battery 11 has thermal runaway, the battery 11 can be moved from the battery rack 1 to the holding mechanism 7 through the transfer mechanism 2. When it is determined that the battery 11 has a fault, the battery 11 can be dropped into the fire extinguisher box 3 through the holding mechanism 7, and the faulty battery 11 can be handled in time to avoid further losses. At the same time, if the transfer mechanism fails during the transfer of the battery 11, the battery 11 can be sprayed by the first spray part and the second spray part to cool the battery 11, thereby avoiding the failure of the transfer link during the transfer of the battery 11 and the failure to cool the battery 11 in time.

[0084] like Figure 1-9As shown, a preferred embodiment, a battery compartment for a charging and swapping station includes an outer shell 8, an automatic door 81, a ventilation control device 92, a battery rack 1, a retaining mechanism 7, a transfer mechanism 2, a sprinkler mechanism, a fire extinguishing box 3 that can accommodate batteries 11, a liquid storage device 4 and a water pump 5.

[0085] A plurality of automatic doors 81 are movably connected to the housing 8, and a ventilation control device 92 is arranged on the housing 8 and is arranged to enable the automatic door 81 to be opened. In this way, the ventilation control device 92 controls the automatic door 81 to be opened, and the smoke exhaust and pressure relief can be opened after the battery 11 has thermal runaway. There are two battery racks 1, and the battery rack 1 is located in the housing 8. The fire box 3 is arranged on the battery rack 1. The holding mechanism 7 is arranged on the battery rack 1 and is located above the fire box 3. The holding mechanism 7 is arranged to carry the battery 11 so that the battery 11 is suspended above the fire box 3 and is released. The battery 11 is switched between the disengaged state of the battery 11 falling into the fire box 3. The transport mechanism 2 is movably arranged between the two battery racks 1, and the transport mechanism 2 is arranged to transport the battery 11 on the battery rack 1 or to transport the battery 11 to the battery rack 1. In this way, when it is determined that the battery 11 has a fault, the battery 11 can be dropped into the fire box 3 through the holding mechanism 7, and the faulty battery 11 can be handled in time to avoid expanding the loss. The spray mechanism includes a spray pipeline, a first spray part and a second spray part. The first spray part and the second spray part are connected to the fire water source through the spray pipeline. The first spray part is configured to spray the battery 11 on the battery rack 1, and the second spray part is configured to spray the area where the transfer mechanism 2 is located. In this way, if the transfer mechanism fails during the transfer of the battery 11, the battery 11 can be sprayed by the first spray part and the second spray part, thereby cooling the battery 11, thereby avoiding the problem that the transfer link fails during the transfer of the battery 11 and the battery 11 cannot be cooled in time. The liquid storage device 4 is arranged on the lower side of the battery rack 1, the water inlet end of the water pump 5 is connected to the liquid storage device 4, and the water outlet end of the water pump 5 is connected to the fire box 3 and the spray mechanism. In this way, the liquid storage device 4 is arranged on the lower side of the battery rack 1, and stores fire water, which makes it more convenient to use water in the fire box 3 and the spray mechanism.

[0086] It should be noted that the number of battery racks 1 may also be one, and the transfer mechanism 2 is located at one side of the battery rack 1. The transfer mechanism 2 is a stacker, and the specific structure of the stacker is prior art and will not be described in detail here.

[0087] like Figure 1 , 3As shown, a preferred embodiment, a battery compartment for a charging and swapping station includes two battery racks 1, and the charging positions on each battery rack 1 are arranged in two rows, and six charging positions are distributed on each row. Among them, on the battery rack 1 with a liquid storage device 4 on the lower side, a lowermost charging position is removed and a retaining mechanism 7 is provided. At the same time, a temperature sensor is provided on each charging position of the battery rack 1; and a temperature sensor is provided on the retaining mechanism 7. The temperature sensor on the charging position can detect the temperature of the battery 11 on each charging position, and the battery 11 with thermal runaway can be detected in time. The temperature sensor on the retaining mechanism 7 can detect the temperature of the battery 11 located on the retaining mechanism 7.

[0088] It should be noted that the temperature sensor is preferably an electric thermal pile sensor, and of course it can also be other sensors that can detect the temperature of the battery 11. The configuration of the battery rack 1 is not unique, and those skilled in the art can select the configuration of the battery rack 1 according to the specific application scenario. For example, the number of charging positions on each column of the battery rack 1 can be four, five, seven, eight, etc.

[0089] like Figure 6-9 As shown, a preferred embodiment, the housing 8 is provided with an installation port for installing the automatic door 81, one side of the automatic door 81 is connected to the housing 8 through a torsion spring hinge 83, and three magnetic seats 91 are provided on the inner side of the automatic door 81 away from the torsion spring hinge 83 along the length direction of the automatic door 81. The housing 8 is provided with three ventilation control devices 92 corresponding to the three magnetic seats 91 on the automatic door 81, and the ventilation control device 92 is an electromagnet, and the ventilation control device 92 can adsorb the corresponding magnetic seats 91 when powered on. When the automatic door 81 rotates from an open state to a closed state, the torsion spring hinge 83 stores elastic potential energy, and the magnetic seat 91 is adsorbed by the ventilation control device 92, so that the automatic door 81 remains in a closed state. When the ventilation control device 92 is no longer powered on, the magnetic force on the ventilation control device 92 disappears, and the automatic door 81 rotates under the action of the torsion spring hinge 83, so that the installation port is exposed, thereby facilitating ventilation of the battery rack 1. The automatic door 81 is preferably three, wherein the side of the housing 8 ( Figure 6 Two automatic doors 81 are arranged on the left side of the housing 8. Figure 6 The right side shown in the figure is provided with an automatic door 81. Meanwhile, the upper side of the side and back side of the shell 8 is provided with a vent 82, which is convenient for ventilating the batteries 11 in the shell 8 during daily use.

[0090] It should be noted that the structures of the electromagnet and the torsion spring hinge 83 are prior art and will not be described in detail here.

[0091] It should be further explained that the above-mentioned setting is not necessary, and those skilled in the art can choose whether to set the above-mentioned structure and the specific structure of the above-mentioned structure based on the specific application scenario. For example, the ventilation control device 92 can use a motor, and a baffle is set on the driving end of the motor. Correspondingly, a fixed hook that can cooperate with the baffle is set on the automatic door 81. During normal use, the fixed hook presses the baffle so that the automatic door 81 cannot be opened. When ventilation is required, the motor drives the baffle to rotate, and the fixed hook is separated from the baffle, so that the automatic door 81 opens. For another example, the setting of the torsion spring hinge 83 is not necessary. One side of the automatic door 81 is connected to the housing 8 through a hinge, and a spring is set on the side where the automatic door 81 is connected to the hinge. One end of the spring presses against the side of the installation port, and the other end of the spring presses against the side where the automatic door 81 is connected to the hinge. For another example, the number of automatic doors 81 can be one, two, four or more. For another example, the number of magnetic seats 91 can be one, two, four or more, and a ventilation control device 92 with the same number of magnetic seats 91 is set. Of course, the magnetic seat 91 may not be provided, and the material of the automatic door 81 may be magnetic metal. For another example, when the battery rack 1 is located indoors, the housing 8 may not be provided. For another example, the automatic door 81 may not be provided.

[0092] like Figure 3 As shown, a preferred embodiment, the liquid storage device 4 is a liquid bag, which can store fire water. The liquid storage device 4 is arranged on the lower side of one of the battery racks 1, and a liquid filling port and a liquid outlet are provided on the liquid storage device 4. The liquid outlet of the liquid storage device 4 is connected to the water inlet end of the water pump 5, and water is supplied to the fire fighting box 3 and the sprinkler mechanism through the liquid outlet, and water is added to the liquid storage device 4 through the liquid filling port. At the same time, the liquid bag is made of a fireproof flexible material red mud cloth, and a layer of fireproof silica gel can also be provided on the surface of the liquid bag. An insulation layer is provided on the outside of the liquid storage device 4, and the insulation layer can be glass wool, composite silicate or polyurethane, etc., and a heating belt is provided between the insulation layer and the liquid storage device 4. In this way, the liquid storage device 4 is made of a fireproof flexible material to avoid leakage of the liquid storage device 4 caused by fire. The provision of the insulation layer and the heating belt can prevent external damage to the water source and prevent the water quality from deteriorating. At the same time, the heating belt can generate heat to prevent the liquid in the liquid storage device 4 from freezing, and can keep the water in the liquid storage device 4 warm through the insulation layer.

[0093] It should be noted that the above-mentioned arrangement of the liquid storage device 4 is not necessary, and those skilled in the art can choose whether to arrange the liquid storage device 4 and the specific structure of the liquid storage device 4 based on the specific application scenario. For example, the liquid storage device 4 can be metal or plastic. For another example, no insulation layer can be provided. For another example, a heating tape can be used instead of a heating rod to heat the liquid in the liquid storage device. For another example, the liquid storage device 4 can be arranged in the middle or upper side of the battery rack 1. For another example, the liquid storage device 4 can be arranged outside the housing 8.

[0094] like Figure 2 As shown, a preferred embodiment, the water inlet end of the water pump 5 is connected to the liquid outlet of the liquid storage device 4, and the water outlet end of the water pump 5 is connected to one end of the sprinkler pipeline, so that it is more convenient to use water in the fire extinguishing box 3 and the sprinkler mechanism.

[0095] It should be noted that when the liquid storage device 4 can be arranged on the upper side of the housing 8, the water pump 5 may not be arranged, and water can be supplied to the fire extinguishing box 3 and the sprinkler mechanism by the gravity of the water.

[0096] In a preferred embodiment, the spray mechanism includes a spray pipeline, four first spray parts and four second spray parts, and the spray pipeline includes a spray main pipe 611 and a spray branch, wherein the spray branch includes a parallel main pipe 612 and four shunt pipes 613. Each first spray part includes a conduit 621 and two first spray pipes 622, and two vertical first spray pipes 622 are arranged on the conduit 621 at intervals. The first spray pipe 622 is provided with a first nozzle 623, and each first nozzle 623 is correspondingly directed to each layer of the battery rack 1. Preferably, the battery rack 1 has a total of six layers, so there are six first nozzles 623 on one spray pipe.

[0097] Each second spraying part includes two second spraying pipes 651 . A downward-facing second spraying head 652 is provided on the second spraying pipe 651 . The second spraying head 652 can spray the area where the transfer mechanism 2 is located.

[0098] One end of the spray main pipe 611 is connected to the water outlet of the water pump 5, and the other end of the spray main pipe 611 is connected to the parallel main pipe 612, and a main valve is provided on the spray main pipe 611. The length direction of the parallel main pipe 612 is perpendicular to the length direction of the spray main pipe 611, and four branch pipes 613 are arranged at intervals along the length direction of the parallel main pipe 612 and are connected to the parallel main pipe 612. One end of two branch pipes 613 is connected to the two ends of the parallel main pipe 612, and the other end is respectively connected to a conduit 621; one end of the remaining two branch pipes 613 is connected to the middle position of the parallel main pipe 612, and the other end is respectively connected to a second spray pipe 651. Branch holes are provided on the parallel main pipe 612 near the four branch pipes 613, wherein the branch holes at the two ends of the parallel main pipe 612 are respectively connected to a conduit 621, and the remaining two branch holes are respectively connected to a second spray pipe 651. A three-way valve is connected to the middle position of the sprinkler main pipe 611, and two ends of the three-way valve are connected to the sprinkler main pipe 611, and the other end of the three-way valve is connected to the fire box 3 through the fire pipeline. In addition, an electric control valve 64 is provided on one end of each conduit 621 connected to the sprinkler branch. An electric control valve 64 is provided on one end of each second sprinkler pipe 651 connected to the sprinkler branch, and the electric control valve 64 is preferably an electric stop valve. At the same time, a return pipe 66 is connected to the conduit 621 on the upper side of the fire box 3, and a return valve 661 is provided on the return pipe 66, and the liquid is discharged into the fire box 3 through the return pipe 66.

[0099] The fire fighting pipeline includes a fire fighting main pipe 31 and a plurality of fire fighting branch pipes 32. One end of the three-way valve is connected to one end of the fire fighting main pipe 31. The other end of the fire fighting main pipe 31 is connected to one end of a plurality of fire fighting branch pipes 32. The other end of the fire fighting branch pipes 32 is connected to the fire fighting box 3. In this way, the flow rate of water flowing into the fire fighting box 3 is reduced through the fire fighting branch pipes 32 to prevent splashing.

[0100] In this way, the first spray head 623 on the first spray pipe 622 can spray the batteries 11 on each layer of the battery rack 1, so that no matter which layer of the battery rack 1 has thermal runaway, the battery 11 can be cooled. The second spray pipe 651 and the second spray head 652 can spray the batteries 11 on the transfer mechanism 2, and the batteries 11 on the transfer mechanism 2 can also be cooled if the transfer mechanism 2 fails during the transfer process.

[0101] It should be noted that the above-mentioned spray mechanism is not unique, and those skilled in the art can select the specific structure of the spray mechanism based on the specific application scenario. For example, the parallel main pipe 612 and the shunt pipe 613 may not be set, and a multi-way valve is set at the water outlet of the water pump 5, and the water outlet of the multi-way valve is directly connected to the conduit 621 of the first spray part or the second spray pipe 651 of the second spray part through a pipeline. Of course, the water outlet of the multi-way valve can also be directly connected to the first spray pipe 622 of the first spray part. For another example, the parallel main pipe 612 may not be set, and a multi-way valve is set on one end of the spray main pipe 611, which is directly connected to the conduit 621 of the first spray part or the second spray pipe 651 of the second spray part through the multi-way valve pipeline. For another example, the number of first nozzles 623 on the first spray pipe 622 can be seven, eight, ten, twelve, etc., or two first nozzles 623 are facing a layer of the battery rack 1. For another example, the number of the second nozzles 652 on the second spray pipe 651 may be two, three, four, five or more. For another example, the electric control valve 64 may be an electromagnetic valve, an electric butterfly valve or an electric ball valve. For another example, the fire main pipe 31 and the plurality of fire branch pipes 32 may not be provided, and a three-way valve may be provided on the first spray part or the second spray part, and one end of the three-way valve is connected to the fire box 3 through a pipeline to realize liquid supply to the fire box 3.

[0102] It should also be noted that the structures of the first nozzle 623 and the second nozzle 652 may be the same or different, and the specific structures are all existing technologies and will not be described in detail here.

[0103] like Figure 4 and 5 As shown, in a preferred embodiment, the holding mechanism 7 includes a battery carrier 72 and a power device 71. There are two power devices 71, which are arranged on the battery rack 1 and located at both ends of the battery carrier 72. The power device 71 has an extended state and a retracted state. When the power device 71 is in the extended state, the battery carrier 72 is mounted on the extended end of the power device 71. When the power device 71 is in the retracted state, the battery carrier 72 is disengaged from the power device 71.

[0104] The battery carrier 72 includes a carrier frame 721, a clamping block 723 and a bracket 724. The number of the clamping blocks 723 is two, and the two clamping blocks 723 are arranged at both ends of the carrier frame 721. The clamping blocks 723 are arranged so that when the electric push rod 711 is in an extended state, the extended end of the electric push rod 711 is located at the lower side of the clamping block 723. The bracket 724 is arranged in an "L" shape. The number of the brackets 724 is two, and the two brackets 724 are located at the lower side of both ends of the carrier frame 721. The battery 11 can be placed on the brackets 724. By controlling the state of the power device 71, the position of the battery carrier 72 is controlled, and the position of the battery 11 on the battery carrier 72 is further controlled.

[0105] The power device 71 includes an electric push rod 711, a slide rail 712, a slider 713 and a telescopic plate 714; the slide rail 712 is connected to the battery rack 1, the slider 713 is connected to the slide rail 712 and slides along the length direction of the slide rail 712, the telescopic plate 714 is connected to the slider 713, one end of the electric push rod 711 is connected to the battery rack 1, and the other end of the electric push rod 711 is connected to the telescopic plate 714. The electric push rod 711 can drive the telescopic plate 714 to move along the length direction of the slide rail 712.

[0106] like Figure 4 As shown, the battery compartment further includes a guide assembly, which includes a sliding member 722 and a sliding fitting member extending in the vertical direction, the sliding fitting member is fixedly connected to the battery rack 1, and the sliding fitting member includes two limiting protrusions 73, a slide groove is formed between the two limiting protrusions 73, one end of the sliding member 722 is inserted into the slide groove with a gap and the other end is fixedly connected to the battery carrier 72. In this way, the guide assembly enables the battery carrier 72 to move in the vertical direction, so that the battery 11 of the battery carrier 72 can accurately fall into the fire box 3.

[0107] The specific use of the above-mentioned holding mechanism 7 is that in the non-working state, the electric push rod 711 is in an extended state, and one end of the telescopic plate 714 is located at the lower side of the clamping block 723 to support the battery carrier 72. When the battery 11 is placed on the battery carrier 72, the electric push rod 711 switches from the extended state to the retracted state, so that the battery carrier 72 and the battery 11 thereon fall accurately into the fire box 3 under the guidance of the guide assembly. In addition, when the thermal failure battery 11 is taken out of the fire box 3 after being cooled, the fire box 3, the battery carrier 72 and the battery 11 therein can be lifted upward together so as to be retained at the holding mechanism 7 again. The electric push rod 711 makes the battery carrier 72 more stable when it is retained.

[0108] It should be noted that the setting of the holding mechanism 7 is not unique, and those skilled in the art can select the specific structure of the holding mechanism 7 based on the specific application scenario. For example, the power device 71 is a magnetic connector or includes a magnetic connector, and the on and off of the circuit controlling the power device 71 can cause the battery carrier 72 to switch between the holding state and the disengaged state. Specifically, the holding mechanism 7 is an electromagnet or an electromagnet. For another example, the electric push rod 711 can be replaced by an oil cylinder or a gas cylinder. For another example, the battery carrier 72 can also adopt other structures, as long as there is a state where the battery carrier 72 is in a disengaged state. For another example, the sliding fitting can be long strips, and a hole is opened on the sliding fitting along the length direction of the sliding fitting to form a slide groove. For another example, the positions of the sliding member 722 and the sliding fitting can be interchanged. For another example, a guide assembly may not be provided.

[0109] The present application also discloses a charging and swapping station, including a battery swapping platform and the above-mentioned battery compartment for the charging and swapping station.

[0110] In this way, when the battery 11 has thermal runaway, the battery 11 can be moved from the battery rack 1 to the holding mechanism 7 through the transport mechanism 2. When it is determined that the battery 11 has a fault, the holding mechanism 7 can make the battery 11 fall into the fire box 3, and the faulty battery 11 can be handled in time to avoid further losses. At the same time, if the transport mechanism fails during the transport of the battery 11, the battery 11 can be sprayed by the first spray part and the second spray part to cool the battery 11, thereby avoiding the problem of failure of the transport link during the transport of the battery 11 and failure to cool the battery 11 in time.

[0111] Please refer to the attached Figure 1-9 , a brief description is given of the process of the above-mentioned charging and swapping station for handling the thermal runaway battery 11.

[0112] When the temperature sensor detects that a battery 11 is in thermal runaway, the stacker removes the battery 11 from the battery rack 1 and transfers it to the battery carrier 72. The temperature sensor on the battery carrier 72 confirms again whether the battery 11 is in thermal runaway. After confirming thermal runaway, the extended end of the electric push rod 711 located on the lower side of the clamping block 723 is retracted, and the battery carrier 72 and the battery 11 on the battery carrier 72 enter the fire extinguishing box 3, thereby achieving cooling of the battery 11. After the cooling is completed, the fork of the stacker moves to the bottom of the fire extinguishing box 3, lifts up the fire extinguishing box 3, the battery carrier 72 and the battery 11 together, and when the battery carrier 72 reaches the position where the holding state is located, the extended end of the electric push rod 711 extends out and lifts up the clamping block 723 of the battery carrier 72. Then the stacker descends to put the fire extinguishing box 3 back to its original position, and the stacker is used to transfer the battery 11 on the battery carrier 72 to the battery exchange platform.

[0113] When it is confirmed that the battery 11 on the battery carrier 72 has not experienced thermal runaway, the battery 11 is removed by a stacker and other transfer devices are used to transfer the battery 11 to the battery exchange platform, waiting for relevant staff to handle it.

[0114] When the battery 11 is in thermal runaway and the stacker fails, the water pump 5 is turned on to pump water from the liquid storage device 4, and the first spray pipe 622 or the second spray pipe 651 corresponding to the failed battery 11 area is turned on to cool the area where the failed battery 11 is located through the first spray pipe 622 or the second spray pipe 651. At the same time, the magnetic suction seat 91 that adsorbs the automatic door 81 is powered off, and the automatic door 81 is opened under the action of the torsion spring hinge 83.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
