A fire-fighting operation and maintenance intelligent monitoring system for a charging and swapping station

Abstract

The application relates to a fire-fighting operation and maintenance intelligent monitoring system of a charging and replacing station. When a sensor detects that the temperature of a power battery in a battery rack is too high, a conveying mechanism conveys the faulty power battery out of the battery rack. At this time, the output power battery is received by a transfer device and is transferred to a fire station for fire-fighting treatment. Through the monitoring system, the faulty power battery can be transferred out of the battery rack and is subjected to individual fire-fighting, so that effective fire-fighting is realized, and other good power batteries are not subjected to indiscriminate fire-fighting, thereby effectively avoiding unnecessary economic losses caused by damage to other power batteries.

Description

Technical Field

[0001] This application relates to the field of fire protection technology for charging and battery swapping stations, and in particular to an intelligent monitoring system for fire protection operation and maintenance of charging and battery swapping stations. Background Technology

[0002] Charging and battery swapping stations, as a rapid energy replenishment method for electric vehicles, are increasingly being built. Typically, a charging and battery swapping station includes a parking platform and a battery compartment. The parking platform is for vehicles waiting to have their batteries swapped, while the battery compartment stores multiple power batteries.

[0003] To prevent fires inside the charging and battery swapping station compartment, temperature sensors are installed. When a battery overheats, fire suppression equipment is activated to spray cooling water inside the compartment, preventing battery explosions and fires, thus improving safety.

[0004] However, the fire-fighting equipment inside traditional charging and battery swapping stations cannot target a single battery. If only one battery overheats and may explode or catch fire, the fire-fighting equipment may spray fire-fighting liquid onto the surfaces of other good batteries, damaging them and causing unnecessary economic losses. Summary of the Invention

[0005] Therefore, it is necessary to provide an intelligent monitoring system for fire protection and maintenance of charging and battery swapping stations, which can effectively solve the problem that it is impossible to deal with a specific power battery during fire protection in charging and battery swapping stations.

[0006] A smart monitoring system for fire protection and maintenance of a charging and battery swapping station includes: a charging and battery swapping station, comprising a battery rack for placing power batteries, a conveying mechanism, and a sensor, wherein the sensor is used to monitor the temperature information of the power batteries in the battery rack, and the conveying mechanism is used to convey the power batteries out of the battery rack; a fire station, located on one side of the charging and battery swapping station, for fire protection of faulty power batteries; and a transfer device, located between the fire station and the battery rack, for receiving the power batteries output by the conveying mechanism and transferring the power batteries into the fire station.

[0007] The aforementioned intelligent monitoring system for fire protection and maintenance of charging and battery swapping stations detects that the temperature of the power batteries in the battery racks is too high. The conveying mechanism then removes the faulty power batteries from the racks. At this point, the discharged power batteries are received by a transfer device and transported to the fire station for fire suppression. This design allows the monitoring system to selectively remove faulty power batteries from the racks and provide individual fire suppression for them. This ensures effective fire suppression while avoiding indiscriminate fire suppression of other good power batteries, thus preventing damage to other power batteries and unnecessary economic losses.

[0008] In some embodiments, the transfer device includes a first driver, a rotating member, and a transfer mechanism disposed on the rotating member. The first driver is used to drive the rotating member to rotate about its own axis so that the transfer mechanism switches back and forth between the battery rack and the fire station. The transfer mechanism is used to receive the power battery output by the conveying mechanism and transfer the power battery to the fire station.

[0009] In some embodiments, the transfer mechanism includes a second driver, a bracket disposed on the rotating member, and a transfer assembly slidably disposed on the bracket. The second driver is used to drive the transfer assembly to move up and down on the bracket, and the transfer assembly is used to receive the power battery output by the conveying mechanism and transfer the power battery to the fire station.

[0010] In some embodiments, the transfer assembly includes a slider, a transfer plate and a base spaced apart on the slider, and a third driver connected between the transfer plate and the base for adjusting the rotation angle of the transfer plate on the slider. The slider is slidably mounted on the bracket and drives the second driver.

[0011] In some embodiments, the transfer mechanism further includes two pulleys spaced apart along the height direction of the support, and a traction belt fitted over the two pulleys, the transfer assembly being connected to the traction belt, and the second driver being used to drive at least one of the pulleys to rotate.

[0012] In some embodiments, the rotating member is provided with a rack that extends around the outer periphery of the axis of the rotating member, and the output shaft of the first driver has a gear that meshes with the rack.

[0013] In some embodiments, the conveying mechanism includes a fourth driver, a transmission assembly, and a movable plate. The movable plate is movably mounted on the battery rack. The fourth driver is connected to the movable plate via the transmission assembly to drive the movable plate to extend or retract from the battery rack. The movable plate is used to hold the power battery.

[0014] In some embodiments, the transmission assembly includes a drive wheel, a driven wheel, and a conveyor belt wound around the drive wheel and the driven wheel, the fourth driver being used to drive the drive wheel to rotate, and the conveyor belt being connected to the moving plate.

[0015] In some embodiments, the battery rack includes multiple racks, all of which are stacked, and each battery rack is provided with the conveying mechanism and the sensor.

[0016] In some embodiments, the charging and battery swapping station further includes a charging and battery swapping compartment, and the fire station includes a fire compartment and a spraying device located in the fire compartment. The fire compartment is connected to the charging and battery swapping compartment, and the spraying device is used to spray liquid onto the power battery in the fire compartment.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] In some embodiments, please refer to Figures 1 to 3This application provides a smart monitoring system 100 for fire protection and maintenance of a charging and battery swapping station, including a charging and battery swapping station 10, a fire station 20, and a transfer device 30. The charging and battery swapping station 10 includes a battery rack 12 for housing power batteries 200, a conveying mechanism 13, and a sensor 14. The sensor 14 monitors the temperature of the power batteries 200 in the battery rack 12, and the conveying mechanism 13 transports the power batteries 200 out of the battery rack 12. The fire station 20 is located on one side of the charging and battery swapping station 10 and is used for fire protection of faulty power batteries 200. The transfer device 30 is located between the fire station 20 and the battery rack 12 and is used to receive the power batteries 200 output from the conveying mechanism 13 and transfer them into the fire station 20.

[0036] In the aforementioned intelligent monitoring system 100 for fire protection and maintenance of the charging and battery swapping station, when sensor 14 detects that the temperature of the power battery 200 on the battery rack 12 is too high, the conveying mechanism 13 will transport the faulty power battery 200 out of the battery rack 12. At this time, the output power battery 200 is received by the transfer device 30 and transferred to the fire station 20 for fire protection. This design allows the monitoring system 100 to selectively transfer faulty power batteries 200 out of the battery rack 12 and provide individual fire protection for them. This ensures effective fire protection while avoiding indiscriminate fire protection of other good power batteries 200, thus effectively preventing damage to other power batteries 200 and unnecessary economic losses.

[0037] It should be noted that when the transfer device 30 transfers the faulty power battery 200 to the fire station 20, the fire station 20 can carry out fire-fighting treatment, such as spraying liquid to cool it down; or using burial to isolate oxygen, etc.

[0038] The transfer device 30 receives the power battery 200 and transports it to the fire station 20. Its structure can be designed in various ways. For example, the transfer device 30 can be designed as a conveyor belt 13c or a conveyor roller, with one end used to receive the power battery 200 transported by the conveyor mechanism 13 and the other end used to transport the power battery 200 to the fire station 20. Alternatively, the transfer device 30 can also be designed as a robotic arm or other equipment.

[0039] It should also be noted that sensor 14 is a device capable of monitoring the temperature of the power battery 200; it can be a temperature sensor. When the temperature detected by sensor 14 exceeds a set temperature, the power battery 200 is determined to be in a faulty state. At this time, the controller can control the conveying mechanism 13 and the transfer device 30 to operate sequentially based on the feedback temperature information. The controller can be a microcontroller, programmable logic controller, etc. Furthermore, the controller can control the conveying mechanism 13 and the transfer device 30 using wireless signal control, etc.

[0040] In addition, the conveying mechanism 13 needs to convey the power battery 200 out of the battery rack 12. There are many ways to achieve this. For example, the conveying mechanism 13 can be a cylinder, hydraulic cylinder, electric cylinder or other equipment, which uses telescopic action to push the power battery 200 out of the battery rack 12; or, the conveying mechanism 13 can also be a combination structure of motor and belt, chain or other components.

[0041] Further, please refer to Figure 3 and Figure 4 The transfer device 30 includes a first driver 31, a rotating member 32, and a transfer mechanism 33 mounted on the rotating member 32. The first driver 31 drives the rotating member 32 to rotate around its own axis, allowing the transfer mechanism 33 to switch back and forth between the battery rack 12 and the fire station 20. The transfer mechanism 33 receives the power battery 200 output from the conveying mechanism 13 and transfers the power battery 200 into the fire station 20. Therefore, when the sensor 14 detects an abnormal temperature in the power battery 200, the first driver 31 drives the rotating member 32 to rotate, causing the transfer mechanism 33 to face the battery rack 12 and cooperate with it. When the transfer mechanism 33 receives the power battery 200, the second driver 36 drives the rotating member 32 to rotate, causing the transfer mechanism 33 to face the fire station 20, and the power battery 200 is transported into the fire station 20 through the transfer mechanism 33. This ensures that the faulty power battery 200 can be effectively transferred into the fire station 20.

[0042] It should be noted that the first driver 31 drives the rotating part 32 to rotate around its own axis in various ways. For example, the first driver 31 and the rotating part 32 can be driven by gear 311 meshing; or the first driver 31 and the transmission part can be connected by belt or chain to achieve transmission.

[0043] To make the rotation of the rotating component 32 smoother, a bearing 322 can be installed inside the charging and battery swapping station 10, and the rotating component 32 is mounted on the bearing 322 via a rotating shaft 321. The first driver 31 can be a motor.

[0044] Furthermore, please refer to Figure 4The transfer mechanism 33 includes a second driver 36, a bracket 34 mounted on the rotating member 32, and a transfer assembly 37 slidably mounted on the bracket 34. The second driver 36 drives the transfer assembly 37 to move up and down on the bracket 34. The transfer assembly 37 receives the power battery 200 output by the conveying mechanism 13 and transfers the power battery 200 to the fire station 20. Thus, the transfer assembly 37 can move up and down on the bracket 34 under the action of the second driver 36. When the faulty power battery 200 is at a higher position, the second driver 36 can drive the transfer assembly 37 to rise, keeping it at or near the same height as the faulty power battery 200. Then, the first driver 31 drives the rotating member 32 to rotate, causing the transfer assembly 37 to face the battery rack 12, so as to stably receive the power battery 200 delivered by the conveying mechanism 13, making firefighting more stable.

[0045] It should be noted that the transfer component 37 can move up and down on the bracket 34. The second driver 36 can be directly set as a device with telescopic function such as a cylinder, hydraulic cylinder, or electric cylinder; or the second driver 36 can be designed as a combination structure of motor and gear, rack and pinion, etc.

[0046] In some embodiments, please refer to Figure 6 The transfer assembly 37 includes a slider 371, a transfer plate 372 and a base 373 spaced apart on the slider 371, and a third actuator 374. The third actuator 374 is connected between the transfer plate 372 and the base 373 and is used to adjust the rotation angle of the transfer plate 372 on the slider 371. The slider 371 is slidably mounted on the bracket 34 and is driven by the second actuator 36. Thus, when the transfer plate 372 turns towards the fire station 20 under the drive of the rotating member 32, the third actuator 374 can drive the transfer plate 372 to rotate, changing the rotation angle of the transfer plate 372 to make it tilted, so that the power battery 200 can quickly slide into the fire station 20. At the same time, when receiving the power battery 200, the third actuator 374 can drive the slider 371 to move on the bracket 34, so that the transfer plate 372 moves to a position that is at or close to the same height as the power battery 200.

[0047] It should be noted that when the transfer plate 372 receives the power battery 200 from the conveying structure, the third driver 374 can also drive the transfer plate 372 to rotate, raising the end of the transfer plate 372 closer to the battery rack 12, making it easier to transfer the power battery 200 onto the transfer plate 372. The third driver 374 can be, but is not limited to, a cylinder, hydraulic cylinder, electric cylinder, electric push rod, etc.

[0048] To ensure that slider 371 moves smoothly on bracket 34, please refer to... Figure 7A groove 344 can be provided on the bracket 34 along its own height direction, and the slider 371 is disposed in the groove 344. In this case, the second driver 36 can be directly connected to the slider 371, or it can be connected to the slider 371 through a transmission structure. The cross-sectional shape of the groove 344 can be various, such as cross-shaped, square, or dovetail-shaped. Of course, providing a groove 344 on the bracket 34 along its own height direction can also prevent the slider 371 from falling.

[0049] In addition, to facilitate the connection between the third driver 374 and the transfer plate 372, a mounting plate 375 can be connected to the output end of the third driver 374, and the mounting plate 375 can be connected to the transfer plate 372. At the same time, the transfer plate 372 can be designed with a comb-like structure, for example, multiple comb teeth are provided at intervals on the end of the transfer plate 372 away from the slider 371.

[0050] Further, please refer to Figure 5 The transfer mechanism 33 also includes two pulleys 35 spaced apart along the height direction of the bracket 34, and a traction belt 351 fitted onto the two pulleys 35. The transfer assembly 37 is connected to the traction belt 351, and the second driver 36 is used to drive at least one pulley 35 to rotate. Thus, when the position of the transfer assembly 37 needs to be raised or lowered, the second driver 36 drives at least one pulley 35 to rotate, causing the traction belt 351 to move, thereby driving the transfer assembly 37 to lift or lower.

[0051] To ensure smooth lifting and lowering of the transfer assembly 37, two supports 34 can be configured, spaced apart on the rotating component 32. Each support 34 has two pulleys 35 and a traction belt 351 fitted onto the two pulleys 35. The pulleys 35 on one support 34 are connected to the pulleys 35 on the other support 34 via a drive shaft 352. The transfer assembly 37 is connected to the two traction belts 351. When the second drive 36 drives one pulley 35 on one support 34 to rotate, the other pulley 35 will rotate via the traction belt 351. Since the pulleys 35 on the two supports 34 are connected by the drive shaft 352, the pulley 35 on the other support 34 can rotate under the drive of the drive shaft 352. This allows the two traction belts 351 on the transfer assembly 37 to move synchronously, making lifting and lowering smoother and more stable.

[0052] Additionally, please refer to Figure 5 To ensure the stable installation of the pulley 35 on the bracket 34, the bracket 34 may include a first support rod 341 and a second support rod 342 spaced apart side by side. A fixed seat 343 connects the first support rod 341 and the second support rod 342, and the pulley 35 is rotatably connected to the fixed seat 343. In addition, a groove 344 may be provided on the second support rod 342.

[0053] In some embodiments, please refer to Figure 5 The rotating component 32 is equipped with a rack 323, which extends around the outer periphery of the axis of the rotating component 32. The output shaft of the first driver 31 has a gear 311 that meshes with the rack 323. Therefore, the rack 323 is a ring tooth. When the first driver 31 drives the gear 311 to rotate, the rack 323, under the meshing drive of the gear 311, will drive the transmission component to rotate around its own axis, thereby enabling the transfer mechanism 33 to move back and forth between the fire station 20 and the battery rack 12. The first driver 31 can be a motor.

[0054] In some embodiments, please refer to Figure 8 The conveying mechanism 13 includes a fourth driver 131, a transmission assembly 132, and a movable plate 133, which is movably mounted on the battery rack 12. The fourth driver 131 is connected to the movable plate 133 via the transmission assembly 132 to drive the movable plate 133 to extend or retract from the battery rack 12. The movable plate 133 is used to hold the power battery 200. Therefore, when the sensor 14 detects that the power battery 200 is in an abnormal state, the fourth driver 131, through the transmission assembly 132, drives the movable plate 133 to extend outside the battery rack 12. Since the power battery 200 is located on the movable plate 133, it extends outside the battery rack 12 under the drive of the movable plate 133, facilitating reception by the transfer device 30.

[0055] To facilitate reception by the transfer device 30, the movable plate 133 can be designed with a hollow structure. For example, the movable plate 133 has an opening 13g, through which the transfer plate 372 of the transfer device 30 can receive the power battery 200 from the movable plate 133 from bottom to top. For specific embodiments, please refer to [reference needed]. Figure 10 The movable plate 133 includes a first support portion 13h and a second support portion 13i that are parallel and spaced apart, and a connecting portion 13k connecting the first support portion 13h and the second support portion 13i. The first support portion 13h, the second support portion 13i and the connecting portion 13k enclose an opening 13g.

[0056] It should also be noted that the transmission component 132 can have various designs. For example, the transmission component 132 can be designed as a gear 311 and rack 323 structure; it can also be designed as a crank slider 371 structure; of course, it can also be designed as a lead screw slider 371 structure, etc.

[0057] Optionally, the fourth drive 131 can be a cylinder, a hydraulic cylinder, or a motor.

[0058] Further, please refer to Figure 8The transmission assembly 132 includes a drive wheel 13a, a driven wheel 13b, and a conveyor belt 13c wound around the drive wheel 13a and the driven wheel 13b. A fourth driver 131 drives the drive wheel 13a to rotate, and the conveyor belt 13c is connected to the moving plate 133. Thus, by driving the drive wheel 13a to rotate via the fourth driver 131, the conveyor belt 13c moves between the drive wheel 13a and the driven wheel 13b, thereby moving the moving plate 133 on the battery rack 12.

[0059] For convenient connection between conveyor belt 13c and moving plate 133, please refer to... Figure 9 The battery rack 12 has a movable hole 122. The conveyor belt 13c and the movable plate 133 are located on both sides of the movable hole 122 and are connected by a connector 13f. The fourth driver 131 is fixed to the battery rack 12 by a support 123. The fourth driver 131 can be a motor. The movable hole 122 not only allows the connector 13f to connect the movable plate 133 and the conveyor belt 13c, but also allows the connector 13f to move the movable plate 133. Therefore, the movable hole 122 should be designed as a strip-shaped hole, with its extension direction consistent with the movement direction of the movable plate 133.

[0060] To ensure smooth movement of the movable plate 133, a guide rail structure or a belt structure can be designed between the movable plate 133 and the battery rack 12. For example, the transmission assembly 132 also includes two spaced guide wheels 13d and a guide belt 13e fitted onto the two guide wheels 13d. The guide belt 13e and the conveyor belt 13c are arranged side by side and spaced apart. A drive shaft is connected between the driven wheel 13b and the guide wheel 13d. The movable plate 133 is connected to both the guide belt 13e and the conveyor belt 13c. At this time, the conveyor belt 13c and the guide belt 13e jointly drive the movable plate 133 to move. In addition, to facilitate stable installation of the guide wheels 13d, two fixed plates 124 can be spaced apart on the battery rack 12, and the guide wheels 13d are rotatably connected to the fixed plates 124.

[0061] In some embodiments, please refer to Figure 3 The battery racks 12 comprise multiple racks, all stacked together, and each rack 12 is equipped with a conveying mechanism 13 and a sensor 14. This facilitates an increase in the energy storage capacity within the charging and battery swapping station 10. Furthermore, the presence of a conveying mechanism 13 and a sensor 14 on each battery rack 12 allows for targeted output of power batteries 200 from different layers of racks 12, enabling the fire station 20 to independently handle faulty power batteries 200.

[0062] To facilitate mutual support between the battery racks 12, a support rod 121 can be installed at the bottom of the battery rack 12. This not only raises the placement position of the power battery 200, but also provides a certain space between the stacked battery racks 12, making it convenient to store the power battery 200.

[0063] In some embodiments, please refer to Figure 3 The charging and battery swapping station 10 also includes a charging and battery swapping compartment 11, and the fire station 20 includes a fire compartment 21 and a spraying device 22 located within the fire compartment 21. The fire compartment 21 is connected to the charging and battery swapping compartment 11, and the spraying device 22 is used to spray liquid onto the power battery 200 within the fire compartment 21. The battery rack 12 and the transfer device 30 are both located within the charging and battery swapping compartment 11. This design facilitates the transport of faulty power batteries 200 to the fire compartment 21, where they are cooled by the spraying device 22.

[0064] It should be noted that the spraying device 22 can spray liquids such as aerosols and heptafluoropropane into the fire chamber 21 to reduce the temperature of the power battery 200.

[0065] The number of fire compartments 21 can be one or more. When there are multiple fire compartments 21, please refer to [the relevant documentation]. Figure 2 The faulty power battery 200 can be transported to the fire compartment 21 by a single transfer device 30; alternatively, multiple transfer devices 30 can be used to transport the faulty power battery 200 to the corresponding fire compartment 21. In some specific embodiments, the fire compartment 21 includes two fire compartments, which are located on opposite sides of the charging and swapping compartment 11, such as the two fire compartments 21 being symmetrically distributed about the charging and swapping compartment 11.

[0066] In some embodiments, please refer to Figure 1 It also includes a charging compartment 40, which is connected to the charging and battery swapping station 10 for vehicles to enter. This allows vehicles to conveniently complete charging or battery swapping operations within the charging and battery swapping station 10.
