Description

Technical Field

[0001] The utility model relates to the technical field of battery storage fire protection, in particular to a fire protection device for an energy storage battery compartment. Background Art

[0002] To improve the energy storage capacity of energy storage battery cells, the current common practice is to increase the number of batteries and adopt a highly compact and dense layout strategy to achieve high-density integration of batteries within a limited space. However, this strategy also carries certain risks: once a single battery cell experiences thermal runaway due to abuse or failure, it can easily trigger a chain reaction in surrounding batteries. During thermal runaway, the battery not only burns but also releases a mixture of high-temperature gases and particles through chemical reactions. These substances are inherently flammable and can easily cause fires. More seriously, the high-temperature gas and particle mixture can exacerbate the thermal runaway situation, further expanding the fire and posing a significant threat to personal and property safety.

[0003] Although energy storage battery warehouse fire protection devices are usually equipped with battery thermal runaway monitoring devices and smoke alarm devices as well as fire-fighting facilities such as fire extinguishers and fire hydrants, this form of fire protection is difficult to effectively curb the rapid spread of toxic smoke and high-temperature gases generated by the fire, which further increases the fire risk. It also brings great challenges and difficulties to the emergency evacuation of personnel and the subsequent rescue work of firefighters, which is not conducive to the intervention of firefighters in the later stage. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, one purpose of the present invention is to propose a fire-fighting device for an energy storage battery compartment, which can effectively curb the rapid spread of toxic smoke and high-temperature gases generated in a fire, and can quickly reduce the temperature inside the compartment, slow down the deterioration of the fire, and facilitate the subsequent rescue and fire-fighting work.

[0006] To achieve the above-mentioned purpose, the present invention proposes a fire-fighting device for an energy storage battery warehouse, comprising a battery thermal runaway monitoring device and a smoke alarm device, wherein the smoke alarm device and the battery thermal runaway monitoring device are respectively arranged in a warehouse body, and the battery thermal runaway monitoring device is electrically connected to a battery cluster, the warehouse body has an internal space for storing a battery cluster, and a plurality of dispersed ventilation openings are opened on the warehouse body, and further comprises: a plurality of closing mechanisms, wherein the closing mechanisms are arranged on the warehouse body, and the plurality of closing mechanisms are respectively arranged at corresponding positions of the ventilation openings, and can seal the ventilation openings; a smoke collection component, wherein the smoke collection component is arranged on the warehouse body The smoke collecting assembly is on the warehouse body, and the smoking end of the smoke collecting assembly extends through the interior of the warehouse body, and the smoke collecting assembly is used to transport the smoke generated inside the warehouse body to a preset location outside the warehouse body for discharge; a liquid nitrogen release mechanism, the liquid nitrogen release mechanism includes a liquid storage unit and a spray pipeline, wherein the liquid storage unit and the spray pipeline are respectively arranged inside the warehouse body, and the liquid storage unit is connected to the spray pipeline, and the liquid storage unit is used to spray liquid nitrogen into the warehouse body through the spray pipeline; the sealing mechanism, the smoke collecting assembly and the liquid storage unit are respectively electrically connected to the battery thermal runaway monitoring device.

At the same time, the smoke collection component continuously inhales the gas in the compartment and transports it to a preset location outside the compartment for discharge, which accelerates the consumption of oxygen in the compartment and the discharge of gas. At the same time, the liquid storage unit sprays liquid nitrogen into the compartment through the spray pipe, which can reduce the combustible gas in the compartment on the one hand, and quickly reduce the temperature in the compartment on the other hand, which can effectively prevent the further development of thermal runaway and explosion, slow down the deterioration of the fire, and facilitate the subsequent rescue and firefighting work.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] The energy storage battery compartment fire-fighting device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the energy storage battery compartment fire protection device of the embodiment of the utility model may include a battery thermal runaway monitoring device (not shown in the figure) and a smoke alarm device (not shown in the figure).

[0029] The smoke alarm device and the battery thermal runaway monitoring device are respectively arranged in the compartment body 1 , and the battery thermal runaway monitoring device is electrically connected to the battery cluster 100 .

[0030] It should be noted that the battery thermal runaway monitoring device described in this embodiment is used to monitor the status of the battery cluster 100 (including but not limited to key parameters such as temperature, voltage, and current) in real time, and process and analyze the collected data to determine whether there is any abnormality. The battery thermal runaway monitoring device may include an integrated sensor system (including but not limited to voltage sensors, temperature sensors, etc.), a data acquisition and transmission system, a central processing unit, an alarm and display system, and other auxiliary components. Since these are prior art components, they will not be described in detail here.

[0031] The smoke alarm device is used to detect the smoke concentration in the warehouse 1 and automatically sound an alarm when the smoke concentration exceeds a set threshold to remind people to pay attention and take measures to reduce casualties and property losses caused by fire. Since it is an existing technology, it will not be described in detail here.

[0032] The storage body 1 has an internal space for storing the battery cluster 100 , and a plurality of dispersed ventilation openings 12 are formed on the storage body 1 .

[0033] Among them, the warehouse body 1 is an energy storage battery warehouse, and the warehouse body 1 is equipped with a fire door. When a fire occurs, the fire door can effectively prevent the spread of the fire, and multiple ventilation holes 12 are distributed in a dispersed manner, which can improve the ventilation performance of the warehouse body 1.

[0034] In this embodiment, the energy storage battery compartment fire protection device further includes: a plurality of closing mechanisms 2, which are provided on the compartment body 1, and the plurality of closing mechanisms 2 are respectively arranged at the corresponding ventilation openings 12, and can close the ventilation openings 12.

[0035] It should be noted that the number of the sealing mechanisms 2 described in this embodiment is the same as the number of the vents 12, so that when the battery cluster 100 thermally runs away, the sealing mechanisms 2 can be used to seal all the vents 12 to ensure the sealing of the compartment 1 and reduce the diffusion of smoke and high-temperature gas.

[0036] The smoke collecting component 3 is arranged on the warehouse body 1, and the smoking end of the smoke collecting component 3 extends through the interior of the warehouse body 1. The smoke collecting component 3 is used to transport the smoke generated inside the warehouse body 1 to a preset location outside the warehouse body 1 for discharge.

[0037] Among them, the preset location can be an area specially equipped with flue gas treatment equipment to ensure that harmful flue gas can be efficiently purified before being discharged. The flue gas can also be introduced into an emergency discharge pool or tank for temporary storage to prevent the uncontrolled spread of harmful gases.

[0038] Liquid nitrogen release mechanism 4, the liquid nitrogen release mechanism 4 includes a liquid storage unit 40 and a spray pipeline 41, wherein the liquid storage unit 40 and the spray pipeline 41 are respectively arranged inside the warehouse body 1, and the liquid storage unit 40 is connected to the spray pipeline 41. The liquid storage unit 40 is used to spray liquid nitrogen into the warehouse body 1 through the spray pipeline 41. The sealing mechanism 2, the smoke collection assembly 3 and the liquid storage unit 40 are respectively electrically connected to the battery thermal runaway monitoring device.

[0039] It should be noted that the battery thermal runaway monitoring device described in this embodiment is also used to control the sealing mechanism 2, the smoke collection assembly 3 and the liquid storage unit 40 when the state of the monitored battery cluster 100 is judged to be abnormal, so as to improve the intelligence of the energy storage battery compartment fire-fighting device, strive to curb it in the early stage of thermal runaway, thereby significantly reducing potential risks and hazards, and improving the overall safety performance of the energy storage battery compartment fire-fighting device. Among them, the standards for abnormal conditions are usually based on multiple key parameters of the battery and its operating environment (for example, temperature, voltage, etc.). These parameters can reflect the health status and safety performance of the battery. Once they deviate from the normal range, they can be regarded as abnormal conditions. For example, when the internal temperature of the battery continues to exceed the threshold (such as 100 degrees Celsius for more than 5 minutes), it should be regarded as an abnormal condition.

[0040] Specifically, when the battery thermal runaway monitoring device detects that the battery cluster 100 has thermal runaway, the battery thermal runaway monitoring device immediately controls the sealing mechanism 2 to close the vent 12, forming a sealed space in the compartment body 1 to prevent the rapid spread of toxic smoke (fume) and high-temperature gas.

[0041] At the same time, the battery thermal runaway monitoring device also opens the flue gas collection component 3 and the liquid storage unit 40. On the one hand, the oxygen in the bin body 1 is consumed by the combustion reaction caused by thermal runaway. On the other hand, as the flue gas collection component 3 continues to inhale it, it is transported to a preset location outside the bin body 1 for discharge. The oxygen in the bin is rapidly consumed by the combustion reaction and the inhalation action, resulting in a decrease in the oxygen concentration. The reduction in oxygen will limit the progress of the combustion reaction, thereby indirectly reducing the generation and accumulation of combustible gases, significantly slowing the spread of the fire, and at the same time realizing the directional and timely discharge of flue gas, further preventing the rapid spread of toxic smoke (flue gas) and high-temperature gas.

[0042] At the same time, the liquid storage unit 40 sprays liquid nitrogen into the warehouse body 1 through the spray pipe 41. The liquid nitrogen will quickly evaporate into nitrogen gas under normal temperature. At the same time, the volume will expand rapidly, occupying the space in the warehouse body 1, thereby diluting and replacing the original combustible gas. Since nitrogen itself does not participate in combustion and does not support combustion, this replacement effect helps to reduce the concentration of combustible gas in the warehouse. In addition, in the process of converting from liquid to gas, it will absorb a large amount of heat energy. Therefore, after releasing the liquid nitrogen, on the one hand, the combustible gas in the warehouse can be reduced, and at the same time, the temperature in the warehouse body 1 can be quickly reduced, which can effectively prevent the further development of thermal runaway and explosion, quickly and effectively reduce the temperature in the warehouse body 1, slow down the deterioration of the fire, and facilitate the subsequent rescue and firefighting work.

[0043] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the closing mechanism 2 includes a tubular body 20 and a rolling shutter door 21 .

[0044] The tube body 20 is arranged on the outer wall of the warehouse body 1 , and the tube body 20 is communicated with the ventilation port 12 , and the rolling shutter door 21 is arranged in the tube body 20 .

[0045] It should be noted that the tube body 20 described in this embodiment is a rectangular tube, so as to be easily adapted to the shape of the rolling door 21, and the rolling door 21 is an electric rolling door.

[0046] Specifically, when the battery thermal runaway monitoring device determines that an abnormality has occurred, it controls the shutter door 21 to open and automatically descend to close the tube body 20 , thereby blocking and closing the vent 12 to prevent rapid diffusion of smoke.

[0047] In one embodiment of the present invention, Figure 3 As shown, the smoke collecting assembly 3 includes an exhaust fan 30 , a smoke collecting pipe 31 , a smoke exhaust pipe 33 and a main smoke collecting pipe 34 .

[0048] Among them, the exhaust fan 30 is arranged on the warehouse body 1, and the exhaust end of the exhaust fan 30 is connected to the smoke collecting pipe 31, the air outlet end of the exhaust fan 30 is connected to the smoke exhaust pipe 33, the smoke collecting pipe 31 extends away from the smoke smoking end of the exhaust fan 30 and penetrates into the interior of the warehouse body 1, the end of the smoke exhaust pipe 33 away from the exhaust fan 30 is connected to the main smoke collecting pipe 34, and the end of the main smoke collecting pipe 34 away from the smoke exhaust pipe 33 is arranged at a preset location.

[0049] It should be noted that the main smoke collecting pipe 34 can be pre-buried underground to reduce the floor space and facilitate the discharge of smoke to a preset location.

[0050] Specifically, when the battery thermal runaway monitoring device determines that an abnormality has occurred, the exhaust fan 30 is controlled to operate. The exhaust fan 30 is turned on to continuously extract the smoke in the bin body 1 through the smoke collection pipe 31, and transports the smoke to a preset location through the smoke exhaust pipe 33 and the main smoke collection pipe 34 for discharge treatment, thereby avoiding the accumulation of harmful gases in the bin body 1. When the battery thermal runaway occurs, a large amount of flammable and explosive gases, such as hydrogen and carbon monoxide, may be generated. Removing these gases in time can reduce the risk of explosion and fire, thereby protecting the safety of personnel and equipment.

[0051] Furthermore, if Figure 3 As shown, the smoke collecting pipe 31 has a plurality of branch smoke collecting ports 32 , and the plurality of branch smoke collecting ports 32 extend through the interior of the bin body 1 .

[0052] Among them, it can be understood that by setting up multiple branch smoke collection ports 32, the smoke diffused in the warehouse body 1 can be sucked in from multiple directions. This layout not only significantly improves the smoke suction efficiency, ensures that the smoke is quickly and effectively guided to the main smoke collection pipe 34, but also greatly shortens the residence time of the smoke in the warehouse body 1, further reducing the potential threat of harmful gases to the environment and people.

[0053] In one embodiment of the present invention, the liquid storage unit 40 is a self-pressurizing liquid nitrogen storage tank.

[0054] It should be noted that the self-pressurizing liquid nitrogen storage tank described in this embodiment is equipped with a double safety automatic control valve, has double safety protection measures, and has the uninterrupted characteristics of continuous pressurization and continuous discharge. Since it is a prior art, it will not be described in detail here. Among them, liquid nitrogen is stored in the self-pressurizing liquid nitrogen storage tank.

[0055] Specifically, through the above design, the battery thermal runaway monitoring device can automatically pressurize the liquid nitrogen to the required pressure level after controlling the liquid storage unit 40 to open. This automatic pressurization function ensures the stability of the liquid nitrogen during transportation and use, without the need for frequent manual intervention, thereby improving work efficiency. At the same time, it can also maintain a continuous supply of liquid nitrogen to meet the needs of long-term or high-intensity use.

[0056] In one embodiment of the present invention, Figure 1 As shown, the spray pipeline 41 includes a first delivery pipeline 410 and a plurality of first nozzles 411 .

[0057] Among them, the first delivery pipeline 410 includes a first main pipeline (not marked in the figure) and multiple first branch pipelines (not marked in the figure), one end of the first main pipeline is connected to the liquid storage unit 40, and the multiple first branch pipelines are respectively connected to the first main pipeline, and the multiple first branch pipelines are respectively arranged above the corresponding battery clusters 100, each first branch pipeline is connected to multiple first nozzles 411, and the first nozzles 411 are facing the battery cluster 100.

[0058] Specifically, the liquid storage unit 40 supplies liquid nitrogen into the first main pipeline, which is then transported from the first main pipeline to the multiple first branch pipelines, so that the liquid nitrogen is sprayed toward the battery cluster 100 through the multiple first nozzles 411. The design of the multiple first nozzles 411 and the multiple first branch pipelines not only greatly increases the coverage area of the battery cluster 100 by the liquid nitrogen, but also rapidly reduces the temperature of the environment surrounding the battery cluster 100 through simultaneous action at multiple points, effectively suppressing the spread of thermal runaway.

[0059] In one embodiment of the present invention, Figure 1 As shown, the warehouse body 1 is divided into an outer chamber 10 and an inner chamber 11 by a partition wall 13 .

[0060] In which, the battery cluster 100 is stored in the inner chamber 11, the liquid storage unit 40 is arranged in the outer chamber 10, and the first branch pipe and the first nozzle 411 are both arranged in the inner chamber 11, the vent 12 is opened on the outer wall of the inner chamber 11, and the closing mechanism 2 is arranged on the outer wall of the inner chamber 11, and the smoking end of the smoke collection assembly 3 is arranged in the inner chamber 11.

[0061] It should be noted that the partition wall 13 described in this embodiment is a fire wall. This wall 13 provides an extremely long fire resistance period, effectively preventing fire from spreading from the inner compartment 11 (where the battery cluster 100 is stored) to the outer compartment 10 (where equipment such as the liquid storage unit 40 is located). This is crucial for preventing fires caused by thermal runaway of the battery cluster 100 and can minimize damage to surrounding equipment and the environment.

[0062] Specifically, the liquid storage unit 40 is located in the outer chamber 10, while the first branch pipe and first nozzle 411 are arranged in the inner chamber 11. This layout allows liquid nitrogen to be sprayed quickly and directly onto the battery cluster 100, rapidly reducing the temperature and suppressing the fire. Furthermore, since the liquid storage unit 40 is independent of the battery storage area, the risk of damage caused by fire is reduced, ensuring the continuity and reliability of the fire extinguishing function.

[0063] Secondly, the vent 12 is located on the outer wall of the inner chamber 11, which is beneficial to the ventilation effect of the inner chamber 11 and reduces the temperature of the inner chamber 11. The sealing mechanism 2 is arranged in the inner chamber 11 and can seal the vent 12, thereby preventing the rapid spread of toxic smoke and high-temperature gases when the battery cluster 100 thermally runs away, thereby reducing pollution to the environment and harm to the surrounding people.

[0064] Furthermore, if Figure 1 As shown, the above-mentioned energy storage battery compartment fire protection device also includes an air-conditioning device 5, which is arranged on the outer wall of the inner compartment 11, and the air outlet of the air-conditioning device 5 is arranged in the inner compartment 11.

[0065] Specifically, the air conditioning device 5 can provide conditioned cooling or heating to the inner chamber 11, thereby achieving precise temperature control of the environment surrounding the battery cluster 100. Because battery performance and life are significantly affected by temperature, maintaining an appropriate temperature range helps extend battery life, improve energy storage efficiency, and reduce performance degradation caused by excessively high or low temperatures.

[0066] Furthermore, if Figure 1 As shown, the above-mentioned energy storage battery compartment fire protection device also includes a spray mechanism 6, which includes a pump body 60, a second delivery pipeline 61 and a plurality of second nozzles 62.

[0067] Among them, one end of the pump body 60 is connected to the second delivery pipeline 61, and the other end of the pump body 60 is connected to the external water supply pipeline through an external pipe, and the pump body 60 is arranged in the outer chamber 10, and the second delivery pipeline 61 includes a second main pipeline and multiple second branch pipelines, wherein one end of the second main pipeline is connected to the pump body 60, and the other end of the second main pipeline passes through the partition wall 13 and is arranged in the inner chamber 11, and multiple second branch pipelines are respectively connected to the second main pipeline, and multiple second branch pipelines are all arranged in the inner chamber 11, and each second branch pipeline is connected to multiple second nozzles 62.

[0068] Specifically, the pump body 60 can draw water from an external source and supply water to multiple second branch pipes through the second main pipe, and spray water into the inner chamber 11 through multiple second nozzles 62 to further suppress the fire. The design combines the second main pipe with multiple second branch pipes, and each second branch pipe is connected to multiple second nozzles 62. This layout allows the spraying water to evenly and quickly cover every corner of the inner chamber 11, effectively improving the fire extinguishing efficiency. The pump body 60 is arranged in the outer chamber 10 and is connected to the external water supply pipe through an external pipe. This design enables the pump body 60 to supply water continuously and stably when a fire occurs, without being affected by the fire in the inner chamber 11, thereby ensuring the sufficiency and reliability of water for fire extinguishing.

[0069] Furthermore, if Figure 1 As shown, the above-mentioned energy storage battery compartment fire-fighting device also includes an emergency treatment cabinet 7, which is arranged in the outer compartment 10.

[0070] Among them, it can be understood that the setting of the emergency treatment cabinet 7 ensures that emergency personnel can immediately launch effective emergency treatment measures. Among them, the emergency treatment cabinet 7 is equipped with fire axes, demolition hooks, gas masks, fire emergency lighting, first aid kits and other equipment to provide emergency personnel with necessary support and protection and reduce the risk of casualties.

[0071] In summary, the energy storage battery compartment fire-fighting device of the embodiment of the present invention can effectively curb the rapid spread of toxic smoke and high-temperature gases generated in a fire, and can quickly reduce the temperature inside the compartment, slow down the deterioration of the fire, and facilitate the subsequent rescue and fire-fighting work.
