[0040] To better understand the above-mentioned objects, features, and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0041] In the following description, many specific details are set forth to facilitate a thorough understanding of the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0042] In some embodiments, the integrated fire prevention and extinguishing energy storage prefabricated cabin includes: at least one energy storage cabinet group, a first transmission pipeline, a first fire extinguishing agent storage tank, and a master controller; the energy storage cabinet group includes a fire monitor; the first transmission pipeline includes at least one first output nozzle and a first switch unit.

[0043] The fire monitors are all electrically connected to the master controller, and the master controller is also electrically connected to the first switch unit; the input interface of the first transmission pipeline is connected to the first fire extinguishing agent storage tank, and the first output nozzles are correspondingly arranged at a first position outside the energy storage cabinet group, and there is a first height between the first position and the top of the energy storage cabinet group; wherein, the master controller is configured to control the first switch unit to open the corresponding first output nozzle according to the fire information determined by the fire monitors; the first height is the height at which the first fire extinguishing agent sprayed by the first output nozzle covers the energy storage cabinet group.

[0044] Exemplarily, taking the case where there are three energy storage cabinet groups as an example, Figure 1 is a schematic structural diagram of an integrated fire prevention and extinguishing energy storage prefabricated cabin provided by the present disclosure, Figure 2 is another schematic structural diagram of an integrated fire prevention and extinguishing energy storage prefabricated cabin provided by the present disclosure, as Figure 1 and Figure 2 shown, the first energy storage cabinet group 101 includes a first fire monitor 111, the second energy storage cabinet group 102 includes a second fire monitor 112, the third energy storage cabinet group 103 includes a third fire monitor 113, and the first fire monitor 111, the second fire monitor 112, and the third fire monitor 113 are all electrically connected to the master controller 200. The first transmission pipeline 300 includes three first output nozzles 310 and a first switch unit 320, and the first switch unit 320 is electrically connected to the master controller 200. The input interface of the first transmission pipeline 300 is connected to the first fire extinguishing agent storage tank 400, and the three first output nozzles 310 are correspondingly arranged at a first position outside the first energy storage cabinet group 101, the second energy storage cabinet group 102, and the third energy storage cabinet group 103, and there is a first height H between the first position and the top of each energy storage cabinet group.

[0045] The fire monitors installed in each energy storage cabinet group will monitor the occurrence of fires in the corresponding energy storage cabinet group in real time. For example, when the first fire monitor 111 detects a fire in the first energy storage cabinet group 101, the master controller 200 will receive the fire information determined by the first fire monitor 111, and the master controller 200 will control the first switch unit 320 of the first transmission pipeline 300 to open the first output nozzle 310 corresponding to the first energy storage cabinet group 101. The first output nozzle 310 is arranged at a first position with a first height H from the top of the first energy storage cabinet group 101. When the first output nozzle 310 is opened at the first position, it can completely cover and spray the first fire extinguishing agent on the first energy storage cabinet group 101 to achieve fire extinguishing for the first energy storage cabinet group 101. Thus, through the fire monitor, the present disclosure can accurately determine the energy storage cabinet group where a fire occurs, thereby achieving accurate positioning of the fire location, and only opening the first output nozzle at the fire occurrence location for fire extinguishing, which can avoid the problem of resource waste during the fire extinguishing process.

[0046] It should be noted that the setting of three energy storage cabinet groups is only an example, and the specific number of energy storage cabinet groups is set according to the actual situation and will not be specifically limited here.

[0047] In some embodiments, the energy storage cabinet group includes at least two energy storage cabinets, at least one temperature sensor, and at least one smoke sensor; both the temperature sensor and the smoke sensor are electrically connected to the fire monitor. The temperature sensor is arranged on one side of the energy storage cabinet, and the smoke sensor is arranged on the other side of the energy storage cabinet; the fire monitor is used to determine fire information according to the information collected by the temperature sensor and the smoke sensor.

[0048] Exemplarily, Figure 3 is a schematic structural diagram of an energy storage cabinet group provided by an embodiment of the present disclosure, as Figure 3As shown in the figure, the energy storage cabinet group 100 includes two energy storage cabinets 120. Both of the two energy storage cabinets 120 include a temperature sensor 1201 and a smoke sensor 1202. The temperature sensor 1201 and the smoke sensor 1202 are both electrically connected to the fire monitor. The two energy storage cabinets 120 are arranged adjacent to each other. A temperature sensor 1201 is provided on one side of one energy storage cabinet 120, and a smoke sensor 1202 is provided on the same side of the other energy storage cabinet 120. A smoke sensor 1202 is provided on the other side of one energy storage cabinet 120, and a temperature sensor 1201 is provided on the same side of the other energy storage cabinet 120. When a fire occurs in any energy storage cabinet 120 within the energy storage cabinet group 100, the corresponding temperature sensor 1201 and smoke sensor 1202 can send the collected temperature information and smoke concentration to the fire monitor. When the fire monitor determines that the collected temperature is higher than the temperature threshold and the smoke concentration is higher than the concentration threshold, it is considered that there is an energy storage cabinet on fire within the energy storage cabinet group 100. Thus, through the above settings, the detection ranges of the temperature sensor 1201 and the smoke sensor 1202 can cover all the energy storage cabinets 120, and further cover the entire energy storage cabinet group 100, thereby improving the accuracy of fire monitoring. Moreover, multiple energy storage cabinets 120 can be provided within the energy storage cabinet group 100. When a fire occurs in one or more energy storage cabinets 120 within the energy storage cabinet group 100, the first output nozzle provided outside the energy storage cabinet group 100 is opened, and the first fire extinguishing agent is sprayed onto all the energy storage cabinets 120 within the entire energy storage cabinet group 100, so as to realize the operation of extinguishing multiple energy storage cabinets 120 with one first output nozzle at the same time, without extinguishing each energy storage cabinet 120 separately, and further avoiding the problem of resource waste during the fire extinguishing process.

[0049] It should be noted that the setting of two energy storage cabinets 120 within the energy storage cabinet group 100 is only an example. Any number of energy storage cabinets 120 can also be provided within the energy storage cabinet group 100. The specific number is set according to actual needs and will not be specifically limited here.

[0050] Exemplarily, the first fire extinguishing agent is water, the first output nozzle is a pendent sprinkler with a spraying coefficient greater than 80, the minimum spraying intensity of the nozzle is 18 L / (min·m²), the water injection port flow rate is 116 L / min, and the water injection port pressure is 2 MPa. Thus, the water mist can be injected into the energy storage cabinet group in a horizontal band shape, ensuring the fire extinguishing effect.

[0051] It should be noted that the fact that the first fire extinguishing agent is water, and the first output nozzle adopts a pendent sprinkler with a spraying coefficient greater than 80, the minimum spraying intensity of the nozzle is 18 L / (min·m²), the water injection port flow rate is 116 L / min, and the water injection port pressure is 2 MPa is only an example. The selection of the specific first fire extinguishing agent and the first output nozzle is set according to the actual situation and will not be specifically limited here.

[0052] Exemplarily, the temperature sensor 1201 can be, for example, a point-type heat fire detector of model JTW-ZD-JBF5110A, and the smoke sensor 1202 can be, for example, a point-type photoelectric smoke fire detector of model JTY-GD-JBF5100A.

[0053] It should be noted that the temperature sensor 1201 can also be a temperature sensor of other models, and the smoke sensor 1202 can also be a smoke sensor of other models. The fact that the temperature sensor 1201 is a JTW-ZD-JBF5110A point-type heat fire detector and the smoke sensor 1202 is a JTY-GD-JBF5100A point-type photoelectric smoke fire detector is only an example and is not specifically limited herein.

[0054] In some embodiments, Figure 4 is a front view of another energy storage cabinet group structure provided by an embodiment of the present disclosure, Figure 5 is a top view of another energy storage cabinet group structure provided by an embodiment of the present disclosure, as Figure 4 and Figure 5 shown, the energy storage cabinet group includes a first energy storage cabinet 121 and a second energy storage cabinet 122.

[0055] The first energy storage cabinet 121 includes a first temperature sensor 1211, a second temperature sensor 1212, a third temperature sensor 1213, a first smoke sensor 1214, a second smoke sensor 1215, and a third smoke sensor 1216; the first temperature sensor 1211, the second temperature sensor 1212, and the third temperature sensor 1213 are sequentially arranged at the second position, the third position, and the fourth position on one side of the first energy storage cabinet 121; the first smoke sensor 1214, the second smoke sensor 1215, and the third smoke sensor 1216 are sequentially arranged at the second position, the third position, and the fourth position on the other side of the first energy storage cabinet 121.

[0056] The second energy storage cabinet 122 includes a fourth temperature sensor 1221, a fifth temperature sensor 1222, a sixth temperature sensor 1223, a fourth smoke sensor 1224, a fifth smoke sensor 1225, and a sixth smoke sensor 1226; the fourth temperature sensor 1221, the fifth temperature sensor 1222, and the sixth temperature sensor 1223 are sequentially arranged at the second position, the third position, and the fourth position on one side of the second energy storage cabinet 122; the fourth smoke sensor 1224, the fifth smoke sensor 1225, and the sixth smoke sensor 1226 are sequentially arranged at the second position, the third position, and the fourth position on the other side of the second energy storage cabinet 122; wherein, the second position, the third position, and the fourth position are three arbitrary positions with different heights on the energy storage cabinet.

[0057] Exemplarily, taking the height of the energy storage cabinet as L, the second position is any position within the detection ranges of the temperature sensor and the smoke sensor that can cover the top area of the energy storage cabinet with a height range greater than 2L / 3 and less than or equal to L; the third position is any position within the detection ranges of the temperature sensor and the smoke sensor that can cover the middle area of the energy storage cabinet with a height range greater than L / 3 and less than or equal to 2L / 3; the fourth position is any position within the detection ranges of the temperature sensor and the smoke sensor that can cover the bottom area of the energy storage cabinet with a height range greater than 0 and less than or equal to L / 3. The first temperature sensor 1211, the second temperature sensor 1212, the third temperature sensor 1213, the fourth temperature sensor 1221, the fifth temperature sensor 1222, and the sixth temperature sensor 1223 are all electrically connected to the fire monitor; the first smoke sensor 1214, the second smoke sensor 1215, the third smoke sensor 1216, the fourth smoke sensor 1224, the fifth smoke sensor 1225, and the sixth smoke sensor 1226 are all electrically connected to the fire monitor.

[0058] For example, when a fire occurs in the first energy storage cabinet 121, the first temperature sensor 1211, the second temperature sensor 1212, and the third temperature sensor 1213 send the detected temperature of the first energy storage cabinet 121 to the fire monitor, and the first smoke sensor 1214, the second smoke sensor 1215, and the third smoke sensor 1216 send the detected smoke concentration of the first energy storage cabinet 121 to the fire monitor. When the fire monitor determines that any received temperature is greater than the temperature threshold, and / or, any received smoke concentration is greater than the concentration threshold, it is determined at this time that a fire has occurred in the first energy storage cabinet 121.

[0059] For example, when a fire occurs in the second energy storage cabinet 122, the fourth temperature sensor 1221, the fifth temperature sensor 1222, and the sixth temperature sensor 1223 send the detected temperature of the second energy storage cabinet 122 to the fire monitor, and the fourth smoke sensor 1224, the fifth smoke sensor 1225, and the sixth smoke sensor 1226 send the detected smoke concentration of the second energy storage cabinet 122 to the fire monitor. When the fire monitor determines that any received temperature is greater than the temperature threshold, and / or, any received smoke concentration is greater than the concentration threshold, it is determined at this time that a fire has occurred in the second energy storage cabinet 122. The total controller controls the corresponding first output nozzle to open for fire extinguishing according to the fire information received from the fire monitor.

[0060] In the present disclosure, each energy storage cabinet in the energy storage cabinet group is provided with a temperature sensor and a smoke sensor, which can achieve accurate judgment of the location of a fire. Moreover, in the present disclosure, temperature sensors and smoke sensors are also provided in the top area, middle area, and bottom area of the energy storage cabinet. When a fire occurs at any position of the energy storage cabinet, the temperature sensor and smoke sensor closest to the fire area can timely collect temperature and smoke concentration information, thereby improving the judgment speed of the occurrence of a fire.

[0061] It should be noted that the second position can also be other positions that can cover the top area of the energy storage cabinet except for the height range greater than 2L / 3 and less than or equal to L. The third position can also be other positions that can cover the middle area of the energy storage cabinet except for the height range greater than L / 3 and less than or equal to 2L / 3. The fourth position can also be other positions that can cover the bottom area of the energy storage cabinet except for the height range greater than 0 and less than or equal to L / 3. No specific limitation is made here.

[0062] In some embodiments, the energy storage cabinet includes at least one harmful gas sensor, an exhaust indicator light, and an exhaust device; the exhaust device includes a second switch unit, a fan, and an opening provided on one side of the energy storage cabinet; the harmful gas sensor is electrically connected to the fire monitor; the fan is electrically connected to the second switch unit; the exhaust indicator light and the second switch unit are both electrically connected to the main controller.

[0063] Exemplarily, when a fire occurs in the energy storage cabinet group, the harmful gas sensor provided in the energy storage cabinet detects the harmful gas in the energy storage cabinet and sends the detection data to the fire monitor. When the fire monitor detects that the concentration of the harmful gas exceeds the harmful gas concentration threshold, it sends a signal to the main controller, and the main controller controls the exhaust indicator light to turn on, indicating that the staff is performing an exhaust operation on the harmful gas in the energy storage cabinet. The aperture area of the opening provided on one side of the energy storage cabinet is not less than 20%. The second switch unit is a fan controller. When the exhaust operation starts, the main controller also controls the second switch unit to turn on the fan, and exhausts through the opening provided on one side of the energy storage cabinet. Moreover, the opening can also be used for pressure relief of the fine water mist. In the present disclosure, the harmful gas sensor, the exhaust indicator light, and the exhaust device cooperate together to achieve the emission of harmful gas in the energy storage cabinet, ensuring the safety of the staff.

[0064] It should be noted that the aperture area of the opening provided on one side of the energy storage cabinet can also be other areas that are conducive to the exclusion of dangerous gases generated by a fire and the pressure relief of the fine water mist. The specific aperture area is set according to the actual situation, and no specific limitation is made here.

[0065] Exemplarily, the harmful gas sensor can be, for example, a combustible gas detector with the model VT3402.

[0066] It should be noted that the harmful gas sensor can also be other models of harmful gas sensors. The VT3402 combustible gas detector as the harmful gas sensor is only an example and is not specifically limited herein.

[0067] In some embodiments, the integrated fire prevention and extinguishing energy storage prefabricated cabin further includes an alarm; the alarm is electrically connected to the master controller; the alarm is used to give an alarm according to the fire information obtained by the master controller.

[0068] Exemplarily, the alarm includes an audible and visual alarm of model JBF5176A, an audible alarm of model JBF5174, and a manual alarm button of model J-SAP-JBF5121. Both the audible and visual alarm and the audible alarm are electrically connected to the master controller. When the master controller obtains a fire in the energy storage cabinet group, the audible and visual alarm and the audible alarm start to give an alarm, sending an alarm to the staff near the energy storage prefabricated cabin, which can avoid endangering the personal safety of the staff. The manual alarm button is electrically connected to the master controller and is arranged inside the energy storage prefabricated cabin. When the staff inside the energy storage prefabricated cabin detects a fire or abnormal temperature, etc., the manual alarm button can be actively triggered to trigger the audible and visual alarm and the audible alarm to start giving an alarm, thereby sending an alarm to the staff near the energy storage prefabricated cabin and avoiding endangering the personal safety of the staff.

[0069] It should be noted that the alarm can also be other models of audible alarms, visual alarms, audible and visual alarms, etc. The audible and visual alarm of model JBF5176A and the audible alarm of model JBF5174 are only examples and are not specifically limited herein.

[0070] In some embodiments, the energy storage cabinet group further includes a main chassis; the fire monitor is arranged inside the main chassis, and the main chassis is made of fireproof material.

[0071] Specifically, since the main chassis is made of fireproof material, when a fire occurs inside the energy storage cabinet group, the fire detector arranged in the main chassis is less affected by external factors and can ensure normal operation.

[0072] In some embodiments, the integrated fire prevention and extinguishing energy storage prefabricated cabin further includes a start-stop switch; the start-stop switch is electrically connected to the first switch unit; wherein, the start-stop switch is used to directly control the first switch unit to open or close all the first output nozzles.

[0073] Specifically, when the staff working inside the energy storage prefabricated cabin detects a fire, they can directly press the start-stop switch to control the first switch unit to directly open all the first output nozzles for fire extinguishing, thereby ensuring the safety of the staff.

[0074] In some embodiments, the first fire extinguishing agent storage tank includes an antifreeze component; the antifreeze component is used to prevent the first fire extinguishing agent in the first fire extinguishing agent storage tank from freezing.

[0075] Exemplarily, when the energy storage prefabricated cabin is set in a cold climate area, the first fire extinguishing agent in the first fire extinguishing agent storage tank may freeze due to the cold, which may cause the first fire extinguishing agent to not pass through the first transmission pipeline during a fire, thereby causing the fire to spread. The present disclosure provides an antifreeze component, such as a heating device, in the first fire extinguishing agent storage tank, so as to ensure that the first fire extinguishing agent will not freeze due to too low temperature during storage, thereby ensuring that the fire protection system in the energy storage prefabricated cabin can also work properly under cold conditions.

[0076] In some embodiments, the energy storage prefabricated cabin integrating fire prevention and extinguishing further includes a second transmission pipeline and a second fire extinguishing agent storage tank; the second transmission pipeline includes at least two second output nozzles and a third switch unit; the input interface of the second transmission pipeline is connected to the second fire extinguishing agent storage tank, and the second output nozzles are respectively arranged at a fifth position outside the energy storage cabinet group, and there is a second height between the fifth position and the top of the energy storage cabinet group; the master controller is electrically connected to the third switch unit; wherein, the master controller is used to control the third switch unit to open the corresponding second output nozzle according to the fire information determined by the fire monitor; the second height is the height at which the second fire extinguishing agent sprayed from the second output nozzle covers the energy storage cabinet group.

[0077] Specifically, when the fire monitor detects a fire in the energy storage cabinet group, the master controller will receive the fire information determined by the fire monitor. The master controller controls the first switch unit of the first transmission pipeline to open the first output nozzle corresponding to the energy storage cabinet group where the fire occurs, and controls the third switch unit of the second transmission pipeline to open the second output nozzle corresponding to the energy storage cabinet group where the fire occurs. The second output nozzle is arranged at a fifth position with a second height from the top of the energy storage cabinet group. When the second output nozzle is opened at the fifth position, the second fire extinguishing agent can completely cover and spray the energy storage cabinet group to achieve fire extinguishing of the energy storage cabinet group. Thus, the present disclosure can accurately determine the energy storage cabinet group where the fire occurs through the fire monitor, thereby realizing accurate positioning of the fire location, and spraying and extinguishing the energy storage cabinet group where the fire occurs with the first fire extinguishing agent and the second fire extinguishing agent together, so as to achieve complete extinguishment of the fire and avoid the risk of re-ignition.

[0078] In some embodiments, the second fire extinguishing agent includes perfluoromethylcyclohexanone.

[0079] Specifically, the fire extinguishing agent should have the characteristics of quickly extinguishing fires and not causing damage to energy storage units and other equipment. Therefore, the present disclosure uses perfluoromethylcyclohexanone as the second fire extinguishing agent. Perfluoromethylcyclohexanone is colorless, odorless, and easy to vaporize. It absorbs heat and takes away a large amount of heat energy through vaporization, thereby achieving the fire extinguishing effect. And because perfluoromethylcyclohexanone will vaporize into perfluoromethylcyclohexanone gas when it enters the energy storage cabinet, it will not remain in the energy storage cabinet after the fire is extinguished, avoiding short-circuiting of the energy storage units in the energy storage cabinet, so as to avoid damage to the energy storage units while effectively extinguishing the fire.

[0080] The specific fire extinguishing work process is as follows: when the temperature detected by any temperature sensor reaches the first temperature threshold, and / or, the smoke concentration detected by any smoke sensor reaches the first concentration threshold, the total controller controls the alarm to trigger an alarm, and the corresponding energy storage cabinet group enters the pre-fire alarm state. The total controller turns on the ventilation system in the energy storage prefabricated cabin and cuts off the auxiliary power supplies of the energy storage converter and the cooling equipment.

[0081] When the temperature detected by any temperature sensor reaches the second temperature threshold, and / or, the smoke concentration detected by any smoke sensor reaches the second concentration threshold, the total controller controls the alarm to trigger an external alarm in the energy storage prefabricated cabin, and the energy storage cabinet group where the fire occurs enters the main fire alarm state. The total controller turns off the ventilation system in the energy storage prefabricated cabin to avoid the problem of the fire getting bigger due to the outside air blowing into the energy storage prefabricated cabin. At the same time, the total controller delays for a preset time, such as 30s, and then turns on the sprinkler system. During the preset time, the monitoring center can remotely judge the fire situation in the energy storage prefabricated cabin to avoid the situation where the sprinkler system is turned on due to the mis-triggering of the start-stop switch by the staff or the failure of each sensor.

[0082] There are multiple energy storage cabinet groups in the energy storage prefabricated cabin. When the nth energy storage cabinet group is determined to have a fire, the nth energy storage cabinet group enters the main fire alarm state, and the fire extinguishing system of the nth energy storage cabinet group starts, and the corresponding output nozzles of each transmission pipeline start to spray the fire extinguishing agent.

[0083] When the (n + 1)-th energy storage cabinet group and the (n - 1)-th energy storage cabinet group receive the fire alarm signal of the n-th energy storage cabinet group (i.e., the energy storage cabinet groups adjacent to the n-th energy storage cabinet group receive the fire alarm signal of the n-th energy storage cabinet group), they enter the pre-fire alarm state: the alarms of the (n + 1)-th energy storage cabinet group and the (n - 1)-th energy storage cabinet group are triggered to give an alarm, and the corresponding output nozzles of each transmission pipeline enter the standby state and can be activated at any time. When the (n + 1)-th energy storage cabinet group and the (n - 1)-th energy storage cabinet group determine that a fire has occurred, the (n + 1)-th energy storage cabinet group and the (n - 1)-th energy storage cabinet group enter the main fire alarm state, and the fire extinguishing systems of the (n + 1)-th energy storage cabinet group and the (n - 1)-th energy storage cabinet group are activated, and the corresponding output nozzles of each transmission pipeline start to spray the fire extinguishing agent. Thus, the energy storage prefabricated cabin can classify the fire situation through the pre-fire alarm state and the main fire alarm state of the energy storage cabinet group. When a fire occurs in an energy storage cabinet group and it enters the main fire alarm state, the adjacent energy storage cabinet groups enter the pre-fire alarm state, so that the corresponding output nozzles of the adjacent energy storage cabinet groups enter the standby state to prevent the spread of the fire. When it is determined that a fire has occurred in the adjacent energy storage cabinet groups, they can also quickly enter the main fire alarm state and open the corresponding output nozzles to efficiently achieve the fire extinguishing response.
