Description

Technical Field

[0001] The present disclosure relates to the field of fire protection technology, and particularly to an integrated fire prevention and extinguishing energy storage prefabricated cabin. Background Art

[0002] As a core component of the energy storage system, the safety and reliability of the energy storage battery prefabricated cabin play a crucial role in the stable operation of the entire power system. Especially the problem of battery thermal runaway has become a key factor affecting the safety of the energy storage battery cabin.

[0003] Battery thermal runaway refers to the phenomenon that under specific conditions, due to factors such as internal short circuit and external heat source, the internal temperature of the battery rapidly rises, which in turn leads to the out-of-control of the internal chemical reaction of the battery, causing battery thermal runaway or even explosion. Once this phenomenon occurs, it will not only cause serious damage to the energy storage battery cabin itself, but also pose a threat to the surrounding environment and personnel safety. In the prior art, the water spray technology is usually used to solve the problem of battery thermal runaway. After the water spray ends, although the fire is extinguished, the battery still remains in a high-temperature state, so there is a high risk of re-ignition. Utility Model Content

[0028] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description to fully understand the present disclosure, but the present disclosure can also 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 the embodiments.

[0030] Figure 1 Schematic structural diagram of an integrated fire prevention and extinguishing energy storage prefabricated cabin provided by an embodiment of the present disclosure, as Figure 1 shown, the energy storage prefabricated cabin includes: an energy storage chamber 100, a control chamber 200, a first transmission pipeline 300, and a second transmission pipeline 400.

[0031] The energy storage chamber 100 includes an energy storage cabinet 110, and the control chamber 200 includes a first fire extinguishing agent storage tank 210 and a second fire extinguishing agent storage tank 220; the input interface 310 of the first transmission pipeline 300 is connected to the first fire extinguishing agent storage tank 300, and the output nozzle 320 of the first transmission pipeline 300 is arranged inside the energy storage cabinet 110; the input interface 410 of the second transmission pipeline 400 is connected to the second fire extinguishing agent storage tank 220, and the output nozzle 420 of the second transmission pipeline 400 is arranged at a first position outside the energy storage cabinet 100; wherein, the first position is a position where the second fire extinguishing agent can cover the energy storage cabinet 110 when the second fire extinguishing agent is ejected from the output nozzle 420 of the second transmission pipeline 400.

[0032] Exemplarily, a plurality of energy storage cabinets 110 are arranged inside the energy storage chamber 100. Figure 1 Exemplarily, 14 energy storage cabinets 110 are drawn. The input interface 310 of the first transmission pipeline 300 is connected to the first fire extinguishing agent storage tank 210, and the input interface 410 of the second transmission pipeline 400 is connected to the second fire extinguishing agent storage tank 220. A plurality of output nozzles 320 are arranged on the first transmission pipeline 300, and the plurality of output nozzles 320 of the first transmission pipeline 300 are arranged in each energy storage cabinet 110 in a one-to-one correspondence. A plurality of output nozzles 420 are arranged on the second transmission pipeline 400, and the plurality of output nozzles 420 of the second transmission pipeline 400 are arranged at a first position outside each energy storage cabinet 110 in a one-to-one correspondence. When a fire breaks out inside the energy storage chamber 100, the first fire extinguishing agent storage tank 210 transports the first fire extinguishing agent into each energy storage cabinet 110 through the first transmission pipeline 300, and ejects the first fire extinguishing agent through the output nozzle 320 of the first transmission pipeline 300 arranged inside the energy storage cabinet 110, so that the temperature inside the energy storage cabinet 110 is effectively reduced. At the same time, the second fire extinguishing agent storage tank 220 transports the second fire extinguishing agent to the output nozzle 420 of the second transmission pipeline 400 arranged at the first position outside the energy storage cabinet 110 through the second transmission pipeline 400, and sprays and covers the second fire extinguishing agent on the energy storage cabinet 110 through the output nozzle 420 of the second transmission pipeline 400 to extinguish the fire and reduce the temperature outside the energy storage cabinet 100. Thus, the present disclosure improves the efficiency of fire control by extinguishing the fire and reducing the temperature inside and outside the energy storage cabinet 100 at the same time, and can reduce the risk of the fire reigniting from inside the energy storage cabinet 100.

[0033] It should be noted that Figure 1 the number of the drawn energy storage cabinets 110 is set to 14 only as an example, and the specific number is set according to the actual situation and is not specifically limited herein.

[0034] In some embodiments, Figure 2 is a schematic structural diagram of an energy storage cabinet provided by an embodiment of the present disclosure, as Figure 2As shown in the figure, the energy storage cabinet includes an energy storage unit 111, an energy storage box 112, and a multi-layer bracket 113. The energy storage unit 111 is arranged inside the energy storage box 112, and the energy storage box 112 is sequentially arranged in each layer of the multi-layer bracket 113; the output nozzle 320 of the first transmission pipeline 300 is correspondingly arranged inside the energy storage box 112.

[0035] Exemplarily, Figure 2 Exemplarily, it is drawn that the energy storage box 112 is arranged in each layer of the multi-layer bracket 113. Figure 2 Exemplarily, it is drawn that there are 7 energy storage boxes 112. A plurality of output nozzles 320 are arranged on the first transmission pipeline 300, and the plurality of output nozzles 320 of the first transmission pipeline 300 are correspondingly arranged in each energy storage box 112 one by one. When a fire breaks out in the energy storage room, it is usually caused by the too high working temperature of the energy storage unit 111. Therefore, the first fire extinguishing agent storage tank transports the first fire extinguishing agent into each energy storage cabinet through the first transmission pipeline 300, and sprays the first fire extinguishing agent through the output nozzle 320 of the first transmission pipeline 300 arranged inside the energy storage box 112 to cool down and extinguish the fire of the energy storage unit 111, so as to effectively reduce the temperature inside the energy storage box 112, thereby reducing the risk of the fire reigniting from the energy storage unit 111 arranged inside the energy storage box 112.

[0036] In some embodiments, Figure 3 is a schematic structural diagram of an energy storage box provided by an embodiment of the present disclosure. Figure 4 is a side view schematic diagram of the structure of an energy storage box provided by an embodiment of the present disclosure, as Figure 3 and Figure 4 shown, the energy storage box 112 includes a temperature sensor 1121 and a gas sensor 1122, and the control room further includes a controller.

[0037] Both the temperature sensor 1121 and the gas sensor 1122 are electrically connected to the controller, and the controller is also electrically connected to the first fire extinguishing agent storage tank and the second fire extinguishing agent storage tank. The controller is used to control the operation of the first fire extinguishing agent storage tank and the second fire extinguishing agent storage tank according to the monitoring results of the temperature sensor 1121 and / or the gas sensor 1122.

[0038] Exemplarily, both the temperature sensor 1121 and the gas sensor 1122 are embedded inside the energy storage tank 112. The temperature sensor 1121 is used to detect the temperature condition inside the energy storage tank 112, and the gas sensor 1122 is used to detect the concentration of harmful gases inside the energy storage tank 112. When the temperature sensor 1121 monitors that the temperature inside the energy storage tank 112 is abnormal, and / or when the gas sensor 1122 monitors that there are harmful gases inside the energy storage tank 112, the controller will receive data information from the temperature sensor 1121 and / or the gas sensor 1122, and the controller controls the first fire extinguishing agent storage tank and the second fire extinguishing agent storage tank to work according to the received data information. Since both the temperature sensor 1121 and the gas sensor 1122 are provided in each energy storage tank 112, the controller can obtain the specific position of the faulty energy storage tank 112, and the staff can conduct key inspections according to the specific fault position.

[0039] In some embodiments, the multi-layer bracket is made of steel or aluminum material.

[0040] Specifically, the energy storage tank is placed on the multi-layer bracket. Considering the size of the energy storage tank and the weight of the energy storage unit placed inside the energy storage tank, the design of the multi-layer bracket needs to consider the convenience of maintenance. Since both steel material and aluminum material have sufficient strength and durability, the multi-layer bracket made of steel or aluminum material in the present disclosure can be used for a long time without damage, so it can meet the convenience of maintenance.

[0041] In some embodiments, the outer shell of the energy storage tank is made of explosion-proof material.

[0042] Specifically, the outer shell of the energy storage tank is made of explosion-proof material, which can effectively reduce the damage of the energy storage unit when a fire breaks out and explodes.

[0043] In some embodiments, continue to refer to Figure 1 , a partition wall 500 made of fireproof material is also provided between the energy storage room 100 and the control room 200.

[0044] Exemplarily, the partition wall 500 can be, for example, a partition door made of fireproof material. When a fire breaks out in the energy storage room 100, the partition door can well separate the energy storage room 100 from the control room 200, preventing the fire from spreading into the control room 200 and reducing the losses caused by the fire. And when a fire breaks out in the energy storage room 100, if there are staff in the energy storage room 100, the staff can enter the control room 200 through the partition door. The partition wall can ensure the safety of the staff, so the staff can monitor the fire situation in the energy storage room 100 in the control room 200.

[0045] It should be noted that the isolation wall can also be other isolation measures for isolating the energy storage room and the control room other than the isolation door, and no specific limitation is made here.

[0046] In some embodiments, the control room further includes an emergency switch, and the emergency switch is used to cut off the power supply of the energy storage cabinet.

[0047] Specifically, when a fire occurs in the energy storage room, the fire is usually caused by abnormal operation of the energy storage unit arranged in the energy storage cabinet. Therefore, the power supply of the energy storage cabinet can be cut off through the emergency switch to effectively avoid the temperature in the energy storage cabinet from rising again, thereby reducing the risk of re-ignition of the energy storage cabinet.

[0048] In some embodiments, the energy storage room further includes a cooling device and a ventilation device; the cooling device is used to maintain the working temperature of the energy storage cabinet, and the ventilation device is used to connect the energy storage room with the external environment.

[0049] Exemplarily, the cooling device can be, for example, an air conditioner, and the ventilation device can be, for example, an exhaust fan. When the energy storage cabinet in the energy storage room is working, the air conditioner can keep the energy storage cabinet at a normal working temperature, thereby reducing the risk of fire caused by the increase in temperature during the operation of the energy storage cabinet. When the energy storage cabinet in the energy storage room is working, the exhaust fan can discharge the dust in the energy storage room to achieve the effect of dust removal. When a fire occurs in the energy storage room, the working efficiency of the air conditioner can be increased to quickly reduce the temperature in the energy storage room, thereby improving the fire extinguishing efficiency. When a fire occurs in the energy storage room, the harmful gases in the energy storage room can be discharged through the exhaust fan.

[0050] It should be noted that the cooling device can be other refrigeration devices other than the air conditioner, and the ventilation device can be other exhaust devices other than the exhaust fan, and no specific limitation is made here.

[0051] In some embodiments, the energy storage room further includes a monitoring device.

[0052] Specifically, a monitoring device can be arranged in the energy storage room. The monitoring device can observe the appearance of all the energy storage cabinets arranged in the energy storage room and can monitor various parameters of the energy storage cabinets. Therefore, the staff can monitor the working conditions of the energy storage cabinets in the energy storage room in real time through the monitoring device. And when the staff discovers the possibility of a fire in the energy storage cabinet through the monitoring device, the staff can quickly take corresponding measures to avoid the occurrence of a fire. And when a fire occurs, the staff can obtain the fire situation in the energy storage room in real time through the monitoring device.

[0053] In some embodiments, the first fire extinguishing agent includes perfluoromethylcyclohexanone.

[0054] 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 first fire extinguishing agent. Perfluoromethylcyclohexanone is colorless, odorless, and easily vaporizable. It absorbs heat and takes away a large amount of heat energy through vaporization, thereby achieving the fire extinguishing effect. And since perfluoromethylcyclohexanone will vaporize into perfluoromethylcyclohexanone gas when entering the energy storage cabinet, it will not remain in the energy storage cabinet after the fire is extinguished, avoiding short-circuiting the energy storage units in the energy storage cabinet, thus achieving effective fire extinguishing while avoiding damage to the energy storage units.

[0055] In some embodiments, the second fire extinguishing agent includes a mixture of coolant and water.

[0056] Exemplarily, the coolant can be, for example, mixed ethylene glycol. Utilizing the non-flammable characteristic of mixed ethylene glycol, after mixing with water, it is sprayed on the outer shell of the energy storage cabinet through the output nozzle of the second transmission pipeline, thereby achieving fire extinguishing while also preventing the spread of fire to surrounding equipment.

[0057] And the coolant can also be used to cool the energy storage cabinet. When the energy storage cabinet is operating normally, the energy storage cabinet can be effectively prevented from rising to an abnormal operating temperature through the cooling of the coolant, thereby reducing the risk of fire. Also, mixing the coolant with water can save water resources and maximize the utilization rate of other resources in the energy storage prefabricated cabin.

[0058] It should be noted that the coolant can also be other non-flammable liquids other than mixed ethylene glycol, and no specific limitation is made here.

[0059] In some embodiments, the control room further includes an alarm, which is electrically connected to the controller. The alarm is used to issue alarm information step by step according to the instructions sent by the controller.

[0060] The specific situation of the first-level early warning is as follows: When the gas sensor detects harmful gases inside the energy storage tank, the controller controls the alarm to issue a first-level gas alarm. When the temperature sensor detects that the temperature inside the energy storage tank is greater than the average temperature of the storage unit, for example, greater than the average temperature by 4°C, the controller controls the alarm to issue a first-level temperature alarm. And since temperature sensors and gas sensors are installed in each energy storage tank, the controller can obtain the specific location of the faulty energy storage tank, and the staff can conduct key inspections based on the specific fault location.

[0061] The specific situation of the secondary warning is as follows: When the gas sensor detects that the concentration of harmful gases inside the energy storage box is higher than the first gas concentration threshold, for example, 20%, the controller controls the alarm to issue a secondary gas alarm. When the temperature sensor detects that the temperature inside the energy storage box is greater than the average temperature of the storage unit, for example, greater than the average temperature by 8°C, the controller controls the alarm to issue a secondary temperature alarm. According to the triggering conditions of the secondary warning, the controller activates the virtual firewall to reduce the energy levels of the energy storage units at the alarm location and the surrounding energy storage units. At the same time, the staff checks the energy storage box that triggers the alarm information. At the same time, the controller controls the refrigeration equipment to increase the refrigeration speed and reduce the room temperature. Among them, the virtual firewall is a measure to quickly discharge the energy storage units that have accidents and their surrounding energy storage units when the secondary warning is triggered, and unconditionally quickly reduces the stored energy of the above-mentioned energy storage units to 0.

[0062] The specific situation of the tertiary warning is as follows: When the gas sensor detects that the concentration of harmful gases inside the energy storage box is higher than the second gas concentration threshold, for example, 50%, the controller controls the alarm to issue a tertiary gas alarm. When the temperature sensor detects that the temperature inside the energy storage box is greater than the average temperature of the storage unit, for example, greater than the average temperature by 12°C, the controller controls the alarm to issue a tertiary temperature alarm. The controller will cut off the power supply of the energy storage box and notify the staff to prepare for a fire in the energy storage cabinet. At the same time, the controller controls the first fire extinguishing agent storage tank and the second fire extinguishing agent storage tank to enter the fire prevention preparation state and be ready to extinguish the fire at any time. The controller also controls the ventilation equipment to be turned on to discharge the harmful gases.

[0063] The specific situation of the quaternary warning is as follows: When the gas sensor detects that the concentration of harmful gases inside the energy storage box is higher than the third gas concentration threshold, for example, 80%, the controller controls the alarm to issue a quaternary gas alarm. When the temperature sensor detects that the temperature inside the energy storage box is greater than the average temperature of the storage unit, for example, greater than the average temperature by 16°C, the controller controls the alarm to issue a quaternary temperature alarm. The controller will cut off the power supply of the energy storage box and control the first fire extinguishing agent storage tank to spray the first fire extinguishing agent into the energy storage cabinet through the first transmission pipeline, and control the second fire extinguishing agent storage tank to spray the second fire extinguishing agent from the first position to the energy storage cabinet through the second transmission pipeline. If there are staff in the energy storage room, the staff can enter the control room through the isolation wall, and the isolation wall can ensure the safety of the staff. The staff can also observe the situation inside the energy storage room in real time through the controller.

[0064] It should be noted that the first gas concentration threshold is 20%, the second gas concentration threshold is 50%, and the third gas concentration threshold is 80%. Greater than the average temperature by 4°C, 8°C, 12°C, and 16°C are all examples. The specific thresholds are set according to the actual situation and are not specifically limited here.
