In a second aspect, the embodiment of the application further provides a fire control method for the energy storage container.
Referring to fig. 4, a fire control method for an energy storage container includes the following steps:
s100, judging whether the interior of the container is in a state of putting out a fire in real time according to the internal environment state of the container;
and S200, if the container is in a state of fire extinguishing, communicating the first supply part and/or the second supply part with a conveying pipeline and correspondingly conveying the first fire extinguishing agent and/or the second fire extinguishing agent into the container.
The arrangement is realized after the container 1 is in a state of fire extinguishing, the fire extinguishing operation is carried out through the first supply part 3 and/or the second supply part 4, the first supply part 3 and the second supply part 4 are connected with the container 1 through the conveying pipeline 2 in the process, and then the required first fire extinguishing agent and/or the second fire extinguishing agent are sent into the container 1, so that the space of the container 1 occupied by the pipelines in the fire fighting system when multiple fire extinguishing agents are used is effectively reduced, the complexity of the whole structure is reduced, and the manufacturing and maintenance cost is reduced.
Optionally, referring to fig. 5, in the step S200, a first supply part and/or a second supply part is connected to a conveying pipeline and correspondingly conveys a first fire extinguishing agent and/or a second fire extinguishing agent into the container, the first supply part 3 is a storage device with a certain volume of the first fire extinguishing agent pre-stored therein, and the method specifically includes the following steps:
s210, acquiring the pressure in the first supply part, and judging whether the pressure in the first supply part is lower than a preset pressure threshold value or not;
s211, if the pressure is not lower than a preset pressure threshold value, connecting the first supply part 3 with a conveying pipeline 2 and conveying a first fire extinguishing agent into the container;
and S212, if the pressure is lower than the preset pressure threshold value, connecting the second supply part with the conveying pipeline 2 and conveying a second fire extinguishing agent into the container.
The arrangement is that the first fire extinguishing agent provided by the first supply part 3 is preferentially used for fire extinguishing operation in the container 1, so that the fire in the container 1 can be controlled as fast as possible under the action of the first fire extinguishing agent with better effect; meanwhile, after the subsequent first fire extinguishing agent is consumed to be lower than the preset pressure threshold value, the second supply part 4 is started to deliver the second fire extinguishing agent to extinguish the fire, and the overall safety of the embodiment of the application is fully improved.
Further, in the step S212, if the pressure is lower than the preset pressure threshold, the fixed connection between the explosion-proof plate on the container 1 and the container is released.
Specifically, after the first fire extinguishing agent in the first supply part 3 is consumed until the formed pressure is lower than the preset pressure threshold, the container 1 is still in a state of waiting for fire extinguishing, which means that a fire disaster occurring in the container 1 cannot be successfully extinguished after a certain volume of the first fire extinguishing agent is consumed, and it is reflected that the state of thermal runaway of a related structure in the container 1 is high, in practical conditions, even if the fire extinguishing operation is subsequently continued to be performed by using the second supply part 4 and the second fire extinguishing agent, the container 1 still has high possibility of pressurization and explosion, therefore, by releasing the fixed connection between the explosion-proof plate 8 and the container 1, the explosion-proof plate 8 can be lifted off the container 1 after the high pressure is formed in the container 1, so that the communication between the inner space and the outer space of the container 1 is realized, the air pressure inside and outside the container 1 is rapidly balanced, and the explosion possibility of the container 1 under the circumstances is effectively reduced.
In some embodiments, in step S200, the first supply part or the second supply part is connected to a transmission pipeline and correspondingly transmits the first fire extinguishing agent or the second fire extinguishing agent to the container, and the first fire extinguishing agent or the second fire extinguishing agent is transmitted only to the placing space 11 in the fire extinguishing state in the container.
Further, in this embodiment, when the first fire extinguishing agent is delivered to the placing space 11 in the container 1, a preset volume of the first fire extinguishing agent is delivered, wherein the setting of the preset volume is adjusted by a technician through the volume of the different placing spaces 11. Meanwhile, in order to satisfy the requirement that the first supply part 3 can still extinguish the fire when all the accommodating spaces 11 are in the state of waiting to extinguish the fire, the total amount of the first fire extinguishing agent pre-stored in the first supply part 3 is not less than the sum of the volumes of the first fire extinguishing agents needed for extinguishing the fire in all the accommodating spaces 11. For example, the space size of each placing space 11 is the same, the volume of the first fire extinguishing agent to be sprayed is X, the first fire extinguishing agent pre-stored in the first supply portion 3 is not less than nX, and n is the number of the placing spaces 11.
In some embodiments, referring to fig. 6, the step S100 of determining whether the interior of the container is in a fire-extinguishing state in real time according to the state of the environment inside the container includes:
s110, obtaining the smoke concentration and temperature in the container, and judging whether the smoke concentration and temperature exceed respective corresponding alarm thresholds in real time;
s120, if only one of the alarm signals exceeds the corresponding alarm threshold value, outputting a fault prompt signal, and stopping the input and output of the working units in the container;
s130, if both exceed the corresponding alarm threshold values, outputting alarm prompt signals, and judging that the interior of the container is in a state of waiting for fire extinguishing after a set time length.
The container 1 can obtain the smoke concentration and temperature in the container 1 through the smoke sensor 60 and the temperature sensor 61. Specifically, in this embodiment, the smoke sensor 60 and the temperature sensor 61 in the sensing device are used to perform real-time monitoring on the smoke concentration and the temperature in each placing space 11, and when the smoke concentration and the temperature exceed the corresponding alarm threshold value, it is determined that the placing space 11 is in the state of fire extinguishing.
In addition, aiming at different placing spaces 11, the alarm threshold values can be set to be the same so as to be convenient for management, and the alarm threshold values are set to be different according to the types of the articles placed in the placing spaces, so that the flexibility and the safety of the fire control of the energy storage container are improved.
The failure prompt signal and the alarm prompt signal can be set according to actual needs, for example, the sound-light alarm 90 is arranged outside the container 1, and the sound-light alarm 90 is used to give out sound-light signals to perform failure prompt or alarm. The fault prompt signal and the alarm prompt signal can be distinguished by using different types or different positions of the audible and visual alarm 90.
In the step S130, the situation that the interior of the container 1 is in the state of waiting for fire extinguishing is determined after the set time length is set, so that the time for relevant personnel to check or process is provided between the time when the alarm prompt signal is sent and the time when the fire extinguishing operation is performed, that is, the set time length is set, and further, under the condition that the relevant personnel can eliminate the dangerous case or the detection of the sensing device is wrong, the relevant personnel can stop the execution of the subsequent fire extinguishing operation in time, and the accuracy of the embodiment of the application in use is improved.
Based on this, in some embodiments, by providing an emergency stop button 91 outside the container 1, which is in control connection with the control device 51, it is sufficient to trigger the emergency stop button 91 when the relevant personnel needs to stop the execution of the subsequent fire extinguishing operation. For example, if the duration that both the smoke concentration and the temperature in the container 1 exceed the respective corresponding alarm thresholds does not exceed the set duration, the emergency stop button 91 is automatically triggered to stop the execution of the subsequent fire extinguishing operation, and if the smoke concentration and the temperature in the container 1 exceed the respective corresponding alarm thresholds and the duration exceeds the set duration, and the relevant personnel do not manually trigger the emergency stop button 91 to stop the execution of the subsequent fire extinguishing operation, the fire extinguishing system automatically executes the subsequent fire extinguishing operation.
