Description

Technical Field

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

[0002] One of the characteristics of large-scale energy storage systems is that the number of batteries is large and the arrangement is relatively dense. The capacity of a single energy storage compartment is 0.5 - 2 MWh, and the number of internal single batteries can reach tens of thousands. The characteristic of concentrated distribution of battery clusters in the energy storage compartment will increase the safety risk of the batteries. If a single battery undergoes thermal runaway due to abuse failure, it is extremely easy to cause a chain reaction among the surrounding batteries. The failure of the internal battery cores leads to thermal runaway of the battery clusters, and finally causes the fire or explosion of the entire energy storage compartment. Once thermal runaway occurs, the battery will release a mixture of high-temperature gases and particles, which are combustible themselves and extremely easy to cause a fire. More seriously, the mixture of high-temperature gases and particles may also cause the combustion of surrounding battery clusters, and even lead to large-scale explosion accidents, posing a great threat to personal safety and property safety.

[0003] Most of the existing fire protection facilities for energy storage battery compartments are pipeline spraying. The time interval from detecting the abnormal temperature of the battery cluster to starting the spraying facility and then to realizing spraying is relatively long, which may lead to complete thermal runaway and explosion combustion of the battery cluster, making the entire energy storage battery compartment face greater losses and greater fire extinguishing difficulties. At the same time, the existing spraying facilities are for the entire energy storage battery compartment. After the spraying is started, the entire energy storage battery compartment will be sprayed. The gas volatilization and maintenance costs after spraying will increase, and at the same time, it will also affect the service life of the battery clusters with normal temperature.

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0027] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to" and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] Since most of the fire-fighting facilities in the existing energy storage battery compartments are pipeline sprinklers, the time interval from detecting the abnormal temperature of the battery cluster to starting the sprinkler facility and then to achieving sprinkling is relatively long. This may lead to a complete thermal runaway and explosion combustion of the battery cluster, causing greater losses to the entire energy storage battery compartment and greater difficulty in fire extinguishing. At the same time, the existing sprinkler facilities are for the entire energy storage battery compartment. After the sprinkler is started, the entire energy storage battery compartment will be subject to sprinkling, which will increase the gas volatilization and maintenance costs after sprinkling. At the same time, it will also affect the service life of the battery clusters without abnormal temperature.

[0031] Therefore, please refer to Figures 1 - 3 , this embodiment provides an energy storage battery compartment with a fire-fighting function, which can immediately perform sprinkling and cooling when detecting the abnormal temperature of a single battery cluster 2. On the one hand, it can prevent the rapid combustion and explosion of the energy storage battery compartment 1 caused by the long start-up time of the sprinkler pipeline, improving the safety factor. On the other hand, it can cool down and prevent explosion of a single battery cluster 2, prevent sprinkling on other normal battery clusters 2, improve their service life, and reduce maintenance costs.

[0032] Please refer to Figure 1 , an energy storage battery compartment with a fire-fighting function includes battery clusters 2, an inspection system and a monitoring and management system. Among them, the battery clusters 2 are arranged in the energy storage battery compartment 1. The inspection system is used to move and monitor the temperatures of multiple battery clusters 2, and the monitoring and management system is used to receive the monitoring information of the inspection system and start cooling and fire extinguishing when the temperature of the battery cluster 2 is abnormal.

[0033] When multiple battery clusters 2 are all arranged on one side of the energy storage battery compartment 1:

[0034] Specifically, there are multiple battery clusters 2, and the multiple battery clusters 2 are arranged at intervals along the first direction on one side of the energy storage battery compartment 1.

[0035] The inspection system includes a group of inspection fire extinguishers 31. Among them, the inspection fire extinguishers 31 are slidably arranged above the multiple battery clusters 2 along the first direction, and the inspection fire extinguishers 31 are configured to monitor the temperatures of the multiple battery clusters 2 located on one side of the energy storage battery compartment 1. Further, the inspection fire extinguishers 31 store fire extinguishing agents inside, and when detecting the abnormal temperature of a single battery cluster 2, they can immediately release the stored fire extinguishing agents to cool down and extinguish the fire for this battery cluster 2.

[0036] Preferably, the fire extinguisher inspection device 31 includes a main body, an infrared dome camera 313, and a telescopic rod 314. The infrared dome camera 313 and the telescopic rod 314 are both connected to the monitoring and management system. The inside of the main body stores the fire extinguishing agent. The infrared dome camera 313 is installed on the main body and is used to monitor the temperature of each battery cluster 2. The telescopic rod 314 is rotatably connected to the main body, and the rotation axis of the telescopic rod 314 is parallel to the first direction. A spray head is provided at one end of the telescopic rod 314 away from the main body, and the fire extinguishing agent inside the main body is released through the spray head.

[0037] Specifically, the main body includes a storage tank 311 and a sliding part 312, and the storage tank 311 is located above the sliding part 312 to facilitate the release of the fire extinguishing agent. The inside of the storage tank 311 stores the fire extinguishing agent. The sliding part 312 is used to connect other components to achieve a sliding setting. The infrared dome camera 313 and the telescopic rod 314 are both provided on the sliding part 312. The telescopic rod 314 is rotatably connected to the sliding part 312 through a rotating shaft structure. The spray head is communicated with the storage tank 311 through the telescopic rod 314, and a ball valve is provided on the telescopic rod 314. The ball valve is provided on the side close to the spray head. The ball valve is connected to the monitoring and management system. When the temperature of a single battery cluster 2 is abnormal, the ball valve opens, and the fire extinguishing agent can be released quickly, shortening the reaction time and thus improving the safety factor.

[0038] Preferably, the telescopic rod 314 is rotatably connected to one end of a connecting rod through a rotating shaft structure, and the other end of the connecting rod is connected to the sliding part 312 to shorten the distance between the spray head and the battery cluster 2 and improve the spraying accuracy.

[0039] By providing the telescopic rod 314 and the rotational connection between the telescopic rod 314 and the sliding part 312, the spraying orientation and spraying distance can be controlled within the spraying range, improving the spraying accuracy.

[0040] Furthermore, the inspection system further includes a first slide rail 32. The first slide rail 32 is arranged along the first direction and is located above the plurality of battery clusters 2. The fire extinguisher inspection device 31 is slidably arranged on the first slide rail 32.

[0041] Still further, a stepper motor 33 and a motor gear are arranged inside the sliding part 312. The stepper motor 33 is connected to the monitoring and management system. The rotation of the motor gear can sequentially engage with a plurality of teeth on the first slide rail 32. The stepper motor 33 is drivingly connected to the motor gear. The stepper motor 33 drives the motor gear to rotate clockwise and counterclockwise, so as to realize the reciprocating movement of the fire extinguisher inspection device 31 along the first slide rail 32.

[0042] Preferably, please refer to Figure 1 and Figure 3, one end of the first slide rail 32 is provided with a first charging station 34. The first charging station 34 is connected to an external power source. The sliding part 312 is provided with a first charging terminal 3121. The fire extinguisher inspection device 31 can slide along the first slide rail 32 to one end of the first slide rail 32 and connect the first charging terminal 3121 to the first charging station 34. On the one hand, the monitoring and management system can monitor the battery power of the fire extinguisher inspection device 31 in real time and drive the first charging terminal 3121 to connect to the first charging station 34, so as to charge the fire extinguisher inspection device 31 in time; on the other hand, when the fire extinguisher inspection device 31 is in a rest state, it can return to the first charging station 34 to reduce the bending deformation caused by the long-term stress on the middle part of the first slide rail 32.

[0043] In addition, the first charging station 34 can wind up or release the water outlet pipe 35 limited in the lock hole of the group of fire extinguisher inspection devices 31.

[0044] Optionally, since perfluorohexanone has a good cooling effect, forms a flooding protection within a certain period of time, and does not harm the human body. At the same time, perfluorohexanone has no corrosion on common metals such as carbon steel, copper, aluminum, stainless steel and other materials, does not damage electronic components and circuits, and does not cause secondary damage. When the temperature in the closed environment increases, the pressure change of perfluorohexanone is much smaller than that of other gaseous fire extinguishing agents. In the same volume, when the ambient temperature is between -40°C and 80°C, the filling density that perfluorohexanone can hold is generally less than 1.8 times that of the boiling point gaseous fire extinguishing agent. Moreover, perfluorohexanone is suitable for low-temperature and high-temperature environments. Therefore, the fire extinguishing agent in this embodiment is selected as perfluorohexanone. Appropriately, the storage tank 311 is selected as a special perfluorohexanone storage tank to avoid leakage.

[0045] Furthermore, the sliding part 312 is provided with a lock hole, one end of the water outlet pipe 35 is limited in the lock hole, and the other end of the water outlet pipe 35 communicates with the water tank 43. Specifically, the water outlet pipe 35 can communicate with the spray head at one end of the telescopic rod 314 through the lock hole. Preferably, a solenoid valve is installed on the water outlet pipe 35, and the solenoid valve is connected to the monitoring and management system. If the perfluorohexanone in the storage tank 311 of the fire extinguisher inspection device 31 has not reached the temperature control effect after spraying, the solenoid valve is opened to spray water on the battery cluster 2 through the spray head to ensure the fire extinguishing and cooling effect.

[0046] The monitoring and management system has a first state. In the first state, when the fire extinguisher inspection device 31 feedbacks that the temperature of one of the battery clusters 2 is abnormal, the monitoring and management system is configured to open the ball valve, adjust the telescopic and rotation of the telescopic rod 314, and control the spray head to release the fire extinguishing agent to the side of the battery cluster 2 with abnormal temperature. If the perfluorohexanone in the storage tank 311 has not reached the temperature control effect after spraying, the solenoid valve is opened to spray water on the battery cluster 2 with abnormal temperature to ensure the fire extinguishing and cooling effect.

[0047] Further, an energy storage battery bin with a fire protection function further includes a sprinkler system, which is connected to the monitoring and management system and is configured to spray fire extinguishing agent and water throughout the energy storage battery bin 1.

[0048] Specifically, the sprinkler system includes a fire extinguishing agent unit, which is connected to the monitoring and management system. The fire extinguishing agent unit includes a fire extinguishing agent storage member 41 and a sprinkler pipe 42. The sprinkler pipe 42 is located above the battery clusters 2, and both ends of the sprinkler pipe 42 communicate with the fire extinguishing agent storage member 41. A plurality of sprinkler heads are arranged at intervals on the sprinkler pipe 42. In this embodiment, the plurality of sprinkler heads are respectively clamped between two adjacent battery clusters 2 on one side of the energy storage battery bin 1 to achieve full-area spraying in the energy storage battery bin 1.

[0049] In other feasible embodiments, the plurality of sprinkler heads can also correspond to the plurality of battery clusters 2 on one side of the energy storage battery bin 1 one by one, and can also achieve full-area spraying in the energy storage battery bin 1.

[0050] Still further, the sprinkler system further includes a water spraying unit, which is connected to the monitoring and management system and is configured to be able to spray water throughout the energy storage battery bin 1.

[0051] Specifically, the sprinkler system includes a water tank 43, and one end of the sprinkler pipe 42 communicating with the fire extinguishing agent storage member also communicates with the water tank 43 to achieve full-area water spraying in the energy storage battery bin 1.

[0052] Preferably, a valve is provided at one end of the sprinkler pipe 42, and the other end of the sprinkler pipe 42 is switched to communicate with the fire extinguishing agent storage member 41 or the water tank 43 through this valve.

[0053] The monitoring and management system also has a second state. In the second state, when the inspection fire extinguisher 31 feedbacks that the temperatures of multiple battery clusters 2 are abnormal, the monitoring and management system is configured to activate the fire extinguishing agent unit to perform full-area spraying of the fire extinguishing agent inside the energy storage battery bin 1. The heat radiation value and the ambient temperature decrease significantly. If the temperature control effect is not achieved after the perfluoromethyl hexanone spraying ends, the water spraying unit is restarted to spray water throughout the energy storage battery bin 1 to ensure the fire extinguishing and cooling effect.

[0054] When the multiple battery clusters 2 are respectively arranged on opposite sides of the energy storage battery bin 1:

[0055] Specifically, a plurality of battery clusters 2 are also arranged at intervals along the first direction on the opposite side of the energy storage battery bin 1.

[0056] Furthermore, the inspection system further includes another group of fire extinguishers 31 for inspection. The fire extinguishers 31 for inspection are slidably arranged above a plurality of battery clusters 2 along a first direction, and the fire extinguishers 31 for inspection are configured to monitor the temperatures of the plurality of battery clusters 2 on the opposite side of the energy storage battery compartment 1. Further, fire extinguishing agents are stored inside the fire extinguishers 31 for inspection. When the temperature of a single battery cluster 2 is detected to be abnormal, the stored fire extinguishing agents can be immediately released to cool down and extinguish the fire for the battery cluster 2.

[0057] Similarly, the fire extinguishers 31 for inspection are connected to the monitoring and management system. When the temperature of a single battery cluster 2 is abnormal, the fire extinguishers 31 for inspection can quickly release the fire extinguishing agents, shortening the reaction time and thus improving the safety factor.

[0058] Furthermore, the inspection system further includes a second slide rail 36. The second slide rail 36 is arranged along the first direction and is located above the plurality of battery clusters 2. The fire extinguishers 31 for inspection are slidably arranged on the second slide rail 36. By reciprocating on the second slide rail 36, the temperature detection of the plurality of battery clusters 2 on the opposite side inside the energy storage battery compartment 1 is realized.

[0059] Still further, one end of the second slide rail 36 is provided with a second charging station 37. The second charging station 37 is connected to an external power supply. The fire extinguishers 31 for inspection are provided with second charging ends. The fire extinguishers 31 for inspection can slide along the second slide rail 36 to one end of the second slide rail 36 and connect the second charging ends to the second charging station 37. On the one hand, the monitoring and management system can monitor the battery power of the fire extinguishers 31 for inspection in real time and drive the second charging ends to be connected to the second charging station 37, so as to charge the fire extinguishers 31 for inspection in time; on the other hand, when the fire extinguishers 31 for inspection are in a rest state, they can return to the second charging station 37 to reduce the bending deformation caused by the long-term force on the middle part of the second slide rail 36.

[0060] In addition, the second charging station 37 can reel in or release a water outlet pipe 35 limited to the keyhole of another group of fire extinguishers 31 for inspection.

[0061] In the first state of the monitoring and management system;

[0062] If one of the fire extinguishers 31 for inspection feedbacks that the temperature of one of the battery clusters 2 is abnormal, the monitoring and management system is configured to control the spray head of one of the fire extinguishers 31 for inspection to release the fire extinguishing agent to one side of the battery cluster 2 with abnormal temperature, and synchronously control the other fire extinguisher 31 for inspection to release the fire extinguishing agent to the side part of the battery cluster 2 with abnormal temperature. If the perfluoromethylcyclohexane in the storage tanks 311 of the two groups of fire extinguishers 31 for inspection has not achieved the temperature control effect after spraying, the solenoid valves of the two fire extinguishers 31 for inspection are opened to spray water on the battery cluster 2 below them to ensure the effect of fire extinguishing and cooling down;

[0063] If another fire extinguisher inspector 31 feeds back that the temperature of one of the battery clusters 2 is abnormal, the monitoring and management system is configured to control the sprinkler head of the other fire extinguisher inspector 31 to release the fire extinguishing agent to one side of the battery cluster 2 with abnormal temperature, and synchronously control one of the fire extinguisher inspectors 31 to release the fire extinguishing agent to the side of the battery cluster 2 with abnormal temperature. If the perfluorocyclohexanone in the storage tanks 311 of the two groups of fire extinguisher inspectors 31 has been completely sprayed and the temperature control effect has not been achieved yet, the solenoid valves of the two groups of fire extinguisher inspectors 31 are opened to spray water on the battery cluster 2 below them to ensure the fire extinguishing and cooling effect is achieved.

[0064] In addition, the fire extinguishing agent unit includes two spray pipes 42. The other spray pipe 42 is located above the battery cluster 2 on the opposite side of the energy storage battery compartment 1, and one end of the spray pipe 42 is blocked, and the other end is communicated with the fire extinguishing agent storage member 41. A plurality of spray heads of the spray pipe 42 are respectively clamped between two adjacent battery clusters 2 on the opposite side of the energy storage battery compartment 1 to achieve the full-area spraying of the energy storage battery compartment 1.

[0065] In other feasible embodiments, a plurality of spray heads can also correspond one by one to a plurality of battery clusters 2 on the opposite side of the energy storage battery compartment 1, and the full-area spraying of the fire extinguishing agent in the energy storage battery compartment 1 can also be achieved.

[0066] Furthermore, the end of the spray pipe 42 communicating with the fire extinguishing agent storage member 41 can also be communicated with the water tank 43 to achieve the full-area spraying of water in the energy storage battery compartment 1.

[0067] Preferably, the fire extinguishing agent unit includes three spray pipes 42, and another spray pipe 42 is located between the battery clusters 2 on both sides.

[0068] In the second state of the monitoring and management system, the two groups of fire extinguisher inspectors 31 feed back that the temperatures of multiple battery clusters 2 are abnormal. The monitoring and management system is configured to activate the fire extinguishing agent unit to perform full-area spraying of the fire extinguishing agent inside the energy storage battery compartment 1. The heat radiation value and the ambient temperature decrease significantly. If the perfluorocyclohexanone spraying is completed and the temperature control effect has not been achieved yet, the water spraying unit is started to perform full-area spraying of water on the energy storage battery compartment 1 to ensure the fire extinguishing and cooling effect is achieved.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
