[0007] In an optional embodiment of the present application, the fire detection switch includes a first relay and a sensor component, and the sensor component is used to control the first relay to be turned on when a fire is detected, so that the fire detection switch is turned on.

In the above scheme, when multiple different types of sensor components on a switch path all detect a fire, the corresponding switch path is turned on, thereby reducing the possibility of the fire extinguishing equipment being accidentally triggered and the possibility of the sensor component missing a report.

[0011] In an optional embodiment of the present application, the sensor component is a smoke sensor, a temperature sensor or an infrared sensor.

[0029] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a fire switch device provided in an embodiment of the present application, the fire switch device 10 may include: multiple fire detection switch units 100; the fire detection switch unit 100 includes one or more fire detection switches 110, and the one or more fire detection switches 110 form at least one switch path, and the fire detection switch 110 is used to be turned on when a fire is detected; any switch path is used to transmit a voltage signal to the fire extinguishing device 30 when all the fire detection switches 110 on it are turned on.

[0031] in, Figure 1 Only three fire detection switch units 100 are shown. It can be understood that the fire detection switch units 100 in the fire protection switch device 10 are not limited to three, and those skilled in the art can adjust them according to actual conditions.

[0032] Specifically, an electrical device that needs to be monitored for fire is used as an example for introduction, wherein the electrical device may be a battery cabinet, a voltage box, or other device that needs electricity. In an electrical layout, multiple electrical devices are usually provided at the same time, that is, multiple electrical devices need to be monitored for fire at the same time. In an embodiment of the present application, a fire detection switch unit 100 is provided in each electrical device, one end of each fire detection switch unit 100 is connected to a power source, and the other end is connected to a fire extinguishing device 30. When a certain switch path in the fire detection switch unit 100 is turned on, the fire extinguishing device 30 starts to work.

[0033] Among them, each fire detection switch unit 100 is connected in parallel, so that each electrical device can be controlled separately, and the fire fighting action in one electrical device will not affect the normal operation of other electrical devices and the fire detection switch unit 100 in the electrical device.

[0034] It is understandable that the fire detection switch unit 100 can be completely set in the electrical equipment, or only a part of it can be set in the electrical equipment. For example, if the fire detection switch unit 100 includes a relay and a sensor component 112, then the sensor component 112 can be set in the electrical equipment, and the relay can be set outside the electrical equipment. The embodiments of the present application do not make specific limitations on this.

[0035] In addition, in addition to electrical equipment, the fire switch equipment provided in the embodiment of the present application can be applied to any area where fire monitoring is required. For example, the fire switch equipment can be applied to warehouses where flammable materials are stored, high-temperature operation workshops, etc., and the embodiment of the present application also does not make specific limitations on this.

[0036] Each fire detection switch unit 100 may include one fire detection switch 110, or may include multiple fire detection switches 110. As an implementation, the fire detection switch 110 may include a relay (named as a first relay 111 for ease of description) and a sensor assembly 112. The first relay 111 may be disposed on the base of the sensor assembly 112, and together form a fire detection switch 110. When the sensor assembly 112 detects a fire, the first relay 111 on the base may be controlled to be turned on, and at this time, it may be considered that the corresponding fire detection switch 110 is turned on.

[0037] It is understandable that in the above embodiment, there are multiple types of sensor components 112 to choose from, such as: smoke sensors, temperature sensors or infrared sensors, etc., and the present application embodiment does not specifically limit this. Those skilled in the art can select a suitable sensor component 112 according to the actual situation of the area where fire monitoring is required, so as to ensure the accuracy of fire extinguishing of the fire switch device 10. Taking the sensor component 112 including a smoke sensor and a temperature sensor as an example, a temperature and smoke sensing base with a model number of 45681-256 can be selected to implement the above fire detection switch 110.

[0038] In this embodiment, the fire switch device 10 provided in the embodiment of the present application may also include: a power supply interface component; the power supply interface component includes: a first interface for providing a voltage signal to the first relay 111 of the fire detection switch 110; a second interface for supplying power to the sensor component of the fire detection switch 110.

[0039] It should be noted that the implementation of the fire detection switch 110 is only an example provided in the embodiment of the present application. For example, the relay in the fire detection switch 110 can use other components that can realize the switch function, such as: a single-pole double-throw switch, etc.; the sensor component 112 in the fire detection switch 110 can be a device with a communication function, used to receive fire information sent by an external device, etc. The embodiment of the present application does not make specific limitations on this, and those skilled in the art can make appropriate adjustments based on the actual situation in combination with the conventional technical means in this field.

[0040] In addition, the embodiment of the present application does not specifically limit the number of components in the fire detection switch 110 . For example, a fire detection switch 110 may include multiple relays or multiple sensor components 112 .

[0041] As an implementation mode, if each fire detection switch unit 100 includes only one fire detection switch 110, and the fire detection switch 110 forms a switch path alone, when the fire detection switch 110 is turned on, a voltage signal is transmitted to the fire extinguishing device 30, so that the fire extinguishing device 30 extinguishes the fire.

[0042] Take the fire detection switch 110 including the first relay 111 and the sensor assembly 112 as an example, please refer to Figure 2 , Figure 2 This is a structural diagram of another fire switch device provided in an embodiment of the present application. In the fire switch device 10, if the fire switch device is applied to an electrical device, in each electrical device, the sensor component 112 in the fire detection switch 110 is connected to the power supply, and one end of the first relay 111 in the fire detection switch 110 is connected to the power supply, and the other end is connected to the fire extinguishing device 30. When the sensor component 112 detects a fire, the first relay 111 is closed, and the fire extinguishing device 30 starts to work.

[0043] The first relay 111 , the fire extinguishing device 30 and the power supply form a switch path.

[0044] Understandably, Figure 2 The implementation of the fire switch device 10 in only one electrical device is shown. When there are multiple electrical devices, the implementation of the fire switch device 10 in each electrical device can be adopted. Figure 2 in the way.

[0045] As another embodiment, if each fire detection switch unit 100 includes a plurality of fire detection switches 110, the plurality of fire detection switches 110 form at least one switch path. At this time, taking the fire detection switch 110 including the first relay 111 and the sensor assembly 112 as an example, there are multiple connection relationships in each fire detection switch unit 100:

[0046] In the first case, the first relays 111 of the plurality of fire detection switches 110 are sequentially connected in series to form a switch path, and the sensor components 112 of the plurality of sequentially connected fire detection switches 110 are sensor components 112 of different types.

[0047] In the second case, the first relays 111 of the plurality of fire detection switches 110 are connected in parallel to form a plurality of switch paths, and the sensor components 112 of the plurality of fire detection switches 110 are the same type of sensor components 112 .

[0048] In a third case, the multiple fire detection switches 110 include at least two types of fire detection switches 110, and different types of fire detection switches 110 are provided with different types of sensor components 112; the first relays 111 of the same type of fire detection switches 110 in the multiple fire detection switches 110 are connected in parallel with each other, and the first relays 111 of different types of fire detection switches 110 are connected in series in sequence to form multiple switch paths.

[0049] The following is a detailed introduction to the above three situations.

[0050] Please refer to Figure 3 , Figure 3 A schematic diagram of the structure of a fire switch device using the first case provided in an embodiment of the present application. For the first case above, in each fire detection switch unit 100, the first relays 111 in the plurality of fire detection switches 110 are sequentially connected in series to form a switch path, and each first relay 111 corresponds to a sensor component 112. Since the type of each sensor component 112 is different, only when each sensor component 112 detects a fire, the formed switch path will be turned on and the fire extinguishing device 30 will start to work.

[0051] For example, in a fire detection switch unit 100, a smoke sensor, a temperature sensor and first relays 111 corresponding to the two sensors are included. Among them, the power supply, the two second relays 111 and the fire extinguishing device 30 constitute a switch path. If only the smoke sensor detects that the smoke in the area where fire monitoring is required is large or only the temperature sensor detects that the temperature rises abnormally in the area where fire monitoring is required, since only one first relay 111 is turned on, the switch path will not be turned on and the fire extinguishing device 30 will not start working; if the smoke sensor detects that the smoke in the area where fire monitoring is required is large, and the temperature sensor simultaneously detects that the temperature rises abnormally in the area where fire monitoring is required, since both first relays 111 are closed, the switch path is turned on and the fire extinguishing device 30 starts working.

[0052] Therefore, in the embodiment of the present application, the first situation described above can reduce the possibility of accidental triggering of the fire extinguishing device 30 .

[0053] Please refer to Figure 4 , Figure 4 A schematic diagram of the structure of a fire switch device using the second case is provided in an embodiment of the present application. For the above second case, in each fire detection switch unit 100, the first relays 111 of multiple fire detection switches 110 are connected in parallel to form multiple switch paths, and each first relay 111 corresponds to a sensor component 112. Among them, a power supply, a first relay 111 and a fire extinguishing device 30 constitute a switch path. Since each sensor component 112 is of the same type, only one sensor component 112 among the multiple sensor components 112 detects a fire, and the corresponding switch path is turned on, and the fire extinguishing device 30 can start working.

[0054] For example, in a fire detection switch unit 100, two smoke sensors and first relays 111 corresponding to the two sensors are included. If one of the smoke sensors detects that there is a lot of smoke in the area where fire monitoring is required, the corresponding first relay 111 is turned on, and the corresponding switch path is turned on, so the fire extinguishing device 30 starts to work.

[0055] If the fire switch device is used in an electrical device, multiple sensor components 112 of the same type can be set in different areas of the electrical device, so that the monitoring of multiple areas of the electrical device can be achieved. Therefore, in the embodiment of the present application, the second situation described above can reduce the possibility of missed reports by the sensor component 112.

[0056] For the above-mentioned third situation, it can be considered as a combination of the above-mentioned first situation and the second situation: each fire detection switch unit 100 includes multiple switch paths, and the first situation is adopted on each switch path, that is, the first relays 111 of fire detection switches 110 of different types are connected in series in sequence; and the second situation is adopted between the multiple switch paths, that is, the first relays 111 of the same type of fire detection switches 110 in multiple fire detection switches 110 are connected in parallel with each other.

[0057] Therefore, the third situation is not described in detail in the present embodiment, and those skilled in the art can refer to the implementation methods of the first and second situations to implement the third situation. It can be understood that in the present embodiment, the third situation can reduce the possibility of accidental triggering of the fire extinguishing device 30 and the possibility of missed alarms of the sensor component 112.

[0058] In the embodiment of the present application, if the fire switch device is used in an electrical device, when a fire is detected in a certain electrical device, as long as all the fire detection switches 110 on a certain switch path in the electrical device are turned on, the fire extinguishing device 30 can be controlled to extinguish the fire, thereby reducing the amount of calculation and reducing the complexity of the operation of the fire switch device 10. In addition, the sensor component 112 and the first relay 111 can cooperate to play the addressing function, which can reduce the complexity of the operation of the fire switch device 10 and the cost of the fire switch device 10. At the same time, compared with the method of logical judgment by the host, the method of relay control is more reliable and time-effective.

[0059] Please refer to Figure 5 , Figure 5 A structural schematic diagram of a fire protection system provided in an embodiment of the present application, the fire protection system may include: the fire protection switch device 10 and the battery management unit 40 in the above-mentioned embodiment; the fire detection switch 110 also includes: a second relay 113, connected to the battery management unit 40; the sensor component 112 is also used to control the second relay 113 to be turned on when a fire is detected; the battery management unit 40 is also connected to the battery in the electrical equipment, and is used to control the battery in the electrical equipment to stop supplying power when it is detected that the second relay 113 is turned on.

[0060] in, Figure 5 The case where only one fire detection switch unit 100 is included in the fire switch device 10 is shown.

[0061] Specifically, the fire detection switch 110 includes a first relay 111 and a sensor assembly 112, and may further include a second relay 113. Similar to the first relay 111, the second relay 113 may be disposed on the base of the sensor assembly 112, and the first relay 111, the second relay 113 and the sensor assembly 112 together form a fire detection switch 110. When the sensor assembly 112 detects a fire, the first relay 111 and the second relay 113 on the base may be controlled to be turned on at the same time.

[0062] The second relay 113 can be connected to the battery management unit 40, and the battery management unit 40 can monitor whether the state of the second relay 113 is on or off. When the second relay 113 is on, the battery management unit 40 can assume that the sensor component 112 corresponding to the second relay 113 has detected a fire. When the battery management unit 40 monitors that the second relays 113 corresponding to all the second relays 111 on a certain switch path are on or the second relay 113 corresponding to a certain first relay 111 is on, it can be assumed that a fire has occurred in the electrical equipment. At this time, the battery management unit 40 can control the battery in the electrical equipment to stop supplying power and perform operations such as alarming.

[0063] It can be understood that, for different situations in the above embodiments, the battery management unit 40 considers that a fire has occurred in the electrical equipment when it detects that the corresponding second relay 113 is turned on. Taking each fire detection switch unit 100 including a plurality of fire detection switches 110 and taking the first situation in the above embodiments as an example, the battery management unit 40 considers that a fire has occurred in the electrical equipment when it detects that each second relay 113 corresponding to the first relay 111 connected in series is closed.

[0064] Therefore, when the sensor component 112 of the fire switch device 10 detects a fire, the corresponding second relay 113 is turned on, and the battery management unit 40 detects the status of the second relay 113 in real time, so it can control the battery to stop supplying power when the second relay 113 is turned on.

[0065] For further information, please refer to Figure 6 , Figure 6 A structural schematic diagram of another fire protection system provided in an embodiment of the present application, the fire protection system, based on the above embodiment, may also include: a fire extinguishing device 30; the fire extinguishing device 30 includes: a fire extinguishing component 302 and a third relay 301, the third relay 301 is connected to the battery management unit 40; the battery management unit 40 is also used to control the battery in the electrical equipment to stop supplying power when it is detected that the third relay 301 is turned on.

[0066] in, Figure 6 Also shown is a case where the fire switch device 10 includes only one fire detection switch unit 100 .

[0067] Specifically, the fire extinguishing component 302 in the fire extinguishing device 30 is connected to the power supply, and the fire extinguishing device 30 may also include a relay (named as the third relay 301 for the convenience of description). Similar to the second relay 113, the third relay 301 can be arranged on the base of the fire extinguishing component 302, and the third relay 301 and the sensor component 112 together form a fire extinguishing device 30. When the fire extinguishing component 302 in the fire extinguishing device 30 starts to work, the third relay 301 on the base can be controlled to be turned on. As an embodiment, the fire extinguishing device 30 may include an aerosol generator.

[0068] The third relay 301 can be connected to the battery management unit 40, and the battery management unit 40 can monitor whether the state of the third relay 301 is on or off. When the third relay is on, the battery management unit 40 can consider that the fire extinguishing component 302 corresponding to the third relay 301 starts to work, that is, a fire has occurred in the electrical device. At this time, the battery management unit 40 can control the battery in the electrical device to stop supplying power and perform operations such as alarming.

[0069] Therefore, when the fire extinguishing component 302 in the fire extinguishing device 30 is working, the corresponding third relay 301 is turned on, and the battery management unit 40 detects the state of the third relay 301 in real time, so it can alarm when the third relay 301 is turned on.

[0070] The fire protection system provided in the embodiment of the present application can be applied to various battery energy storage systems as an implementation method. For example, for a container-type energy storage system, the fire protection switch device 10 can be configured in the control unit of the container battery system; for a station-type energy storage system or an outdoor electric cabinet energy storage system, the fire protection switch device 10 can be configured in the main control cabinet of the energy storage system.

[0071] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
