In some embodiments, each bracket body is horizontally installed on the energy storage battery rack, and the first nozzle 42 installed on the bracket body is located on one side of the battery pack away from the aisle, that is, the first nozzle 42 is located on the back of the corresponding battery pack, so that the first nozzle 42 can spray fire extinguishing agent to the corresponding battery pack, thereby improving the fire extinguishing effect.
Because the middle of the energy storage container is generally provided with the passageway, the battery clusters 30 are respectively positioned at two sides of the passageway, in some embodiments, the first nozzles 42 are arranged at one side of the energy storage battery rack far away from the passageway, so that the fire extinguishing agent sprayed by the first nozzles 42 can be diffused from one side of the battery clusters 30 far away from the passageway to one side close to the passageway, the fire extinguishing agent is more uniformly diffused in the battery compartment 10, and the problem that the fire extinguishing agent is difficult to diffuse at one side of the battery clusters 30 far away from the passageway to cause complete fire extinguishing is avoided.

In some embodiments, the fire fighting entity further comprises a control unit 80, the control unit 80 being electrically connected to the information collecting device 13 and the first nozzle 42. The control unit 80 stores the position mapping relationship between the information acquisition device 13 and the first nozzle 42; in the practical application process, the control unit 80 collects the fire-fighting information collected by the information collection device 13, and controls the corresponding first nozzle 42 to spray the fire extinguishing agent according to the fire-fighting information, so that the fire extinguishing of the energy storage container is realized.
In some embodiments, the information collecting device 13 is mounted on the energy storage battery rack and is located on one side of the energy storage battery rack close to the aisle. Because the passageway is comparatively spacious, the smog that the conflagration produced easily spreads or stretches along the passageway to one side that energy storage battery frame is close to the passageway, consequently installs information acquisition device 13 in the one side that is close to the passageway, and the fire control information that can be quick and accurate reduces the fire control danger of energy storage container.
In some embodiments, each battery cluster 30 includes a first column of battery packs and a second column of battery packs; the number of the battery packs of the first row of battery packs and the second row of battery packs are both N, wherein N is more than or equal to 6 and less than or equal to 10;
the number of the first nozzles 42 distributed on the first row of battery packs is 2-N/2;
the number of the first nozzles 42 distributed on the pack of the second row of batteries is 1 to (N/2-1); and/or
The number of the information acquisition devices 13 arranged on each battery cluster 30 is 2-N/2.
The first nozzles 42 are uniformly and crossly distributed on the first row of battery packs and the second row of battery packs, and by means of the horizontal extension of the support body, the first nozzles 42 are positioned in the middle of the back surfaces of the corresponding battery packs, so that the first nozzles are uniformly distributed on two sides of a passageway of each battery compartment as much as possible, and when a fire breaks out in the battery compartments 10, the first nozzles 42 close to the fire breaking position can spray extinguishing agents to extinguish the fire as soon as possible; meanwhile, nozzles do not need to be arranged on each battery pack, the using amount of the nozzles is reduced, the cost of the energy storage container is reduced, and the fire fighting effect and the cost of the energy storage container are both considered.
In some embodiments, referring to fig. 4, the number of first nozzles 42 disposed on the first column of battery packs is 2; the number of the first nozzles 42 arranged on the second battery pack is 1; namely: three first nozzles 42 are arranged on each battery cluster 30, and the three first nozzles 42 are all positioned on one side of the battery cluster 30 away from the passageway; the first nozzles 42 arranged on the first row of battery packs and the second row of battery packs are distributed in a cross mode, so that the number of the first nozzles 42 and the fire-fighting effect are both achieved, the fire extinguishing agent sprayed out of the first nozzles 42 can reach the fire extinguishing concentration in a very short time, preferably, the fire extinguishing agent sprayed out of the first nozzles 42 starts to be sprayed out by the nozzles, and the fire extinguishing agent sprayed out of the first nozzles 42 in about 10 seconds can reach the fire extinguishing concentration, so that fire extinguishing is achieved.
In some embodiments, referring again to fig. 3, a first nozzle 42 on the first row of battery packs is disposed corresponding to the highest battery pack on the first row of battery packs;
the other first nozzle 42 arranged on the first row of battery packs is arranged at the position of 1/3 h-1/2 h (excluding 1/2) away from the bottom surface 11 of the battery compartment; wherein h is the height of the battery cluster 30;
the first nozzles 42 arranged on the second row of battery packs are positioned in the middle of the second row of battery packs in the vertical direction.
Since the fire extinguishing agent is heavier or has a larger molecular weight than air, when the fire extinguishing agent is sprayed into the air, the fire extinguishing agent gradually diffuses in the direction of gravity, i.e., downward, so as to cover the battery pack at the lower position of the battery pack 30, thereby extinguishing fire. Therefore, one nozzle on each battery cluster 30 is arranged at the highest position of the battery cluster 30, so that the fire extinguishing agent sprayed by the nozzles covers the whole battery cluster 30 in the downward dispersion process, the coverage of the whole battery cluster 30 is realized, the fire-fighting blind area is avoided, and the fire-fighting effect is improved. Since the first nozzles 42 on the first row of battery packs alternate with the first nozzles 42 on the second row of battery packs, the first nozzles 42 on the second row of battery packs are disposed in the middle of the battery cluster 30, which is preferably disposed at a distance h/2-2/3h (excluding the end point 2/3 h) from the bottom 11 of the battery compartment.
Taking the number of the battery packs of each battery cluster 30 as 16 as an example, that is, the number of the battery packs in each row of the battery packs is 8, and the first nozzle 42 positioned at the uppermost side (farthest from the bottom surface of the battery compartment 10) is positioned at the position corresponding to the battery pack at the highest layer in the first row of the battery packs; the first nozzle 42 positioned in the middle is positioned at the position corresponding to the 5 th battery pack when counting from the side of the bottom surface 11 of the battery compartment to the side of the top surface 12 of the battery compartment in the second row of battery packs; the first nozzle 42 located at the lowermost side (closest to the bottom surface of the battery compartment 10) is located at a position corresponding to the 3 rd battery pack in the first row of battery packs as counted from the battery compartment bottom surface 11 side to the battery compartment top surface 12 side.
In some embodiments, referring to fig. 7, the battery compartment is provided with an air return opening, and the number of the information acquisition devices arranged in each battery cluster is not less than 2; the maximum distance between the information acquisition devices on each battery cluster is reduced along with the reduction of the distance between the battery cluster and the air return inlet;
the maximum distance between the information acquisition devices on each battery cluster is the distance between the information acquisition device positioned on the uppermost side of the battery cluster and the information acquisition device positioned on the lowermost side of the battery cluster on each battery cluster.
In general, the specific arrangement of each information collecting device 13 in the battery cluster 30 varies depending on the direction of return air, in relation to the height of the battery cluster 30 and the lateral distance between the return air inlets 21, and the arrangement range of the information collecting devices 13 on each battery cluster 30 (i.e., the distance between the uppermost information collecting device 13 and the lowermost information collecting device 13) decreases as the lateral distance between the battery cluster 30 and the return air inlet 21 decreases.
It should be noted that the energy storage container is further provided with an air conditioner and an exhaust duct, the battery compartment is further provided with a plurality of air outlets, one end of the exhaust duct is communicated with the air conditioner, and the other end of the exhaust duct is communicated with the air outlets. The air outlet and the air return opening 21 are respectively communicated with an air conditioner air outlet and an air conditioner air return opening of an air conditioner. And cold air blown out of the air conditioner is conveyed to the air outlet corresponding to the upper part of each row of battery packs along the exhaust pipeline and is blown out of the battery compartment 10, and the air cooled by the battery packs is pumped back to the air conditioner from the air return opening 21. In some embodiments, a fan is disposed on one side of each battery pack close to the aisle. When the air conditioner during operation, the cold wind of air conditioner is from the upper portion air-out of battery compartment 10, carries the back of each battery cluster 30 along the wind channel, and the fan on each battery pack in battery cluster 30 pumps cold wind to the battery pack front from the battery pack back, finally is retrieved by return air inlet 21, guarantees the flow direction of the air in battery compartment 10, and then reduces information acquisition device 13's quantity, guarantees to survey the accuracy, improves the diffusion of fire extinguishing agent.
Due to the effect of the air conditioner, the main flow direction of the gas in each battery compartment 10 flows from one side of the air outlet to one side of the air return opening 21, so that the information acquisition devices 13 are arranged according to the air return direction of the battery compartment, the number of the required information acquisition devices 13 can be reduced, the accurate detection effect is achieved, and the cost reduction and the consideration of the detection effect are realized.
