With continued reference to fig. 1 and 2, embodiments of the present application provide an energy storage container fire protection system that includes a fire suppression apparatus 10, piping 40, and spray heads. Wherein the spray head is in communication with the fire extinguishing device 10 through a pipe 40. In the fire fighting operation, the fire extinguishing agent contained in the fire extinguishing apparatus 10 is delivered to the spray head through the pipe 40 to be sprayed. The detailed description of each component of the energy storage container fire-fighting system provided by the embodiment of the application is respectively provided below.

The fire extinguishing apparatus 10 provided in the embodiment of the present application is used to contain fire extinguishing agent, and when the fire extinguishing apparatus 10 is disposed, the fire extinguishing apparatus 10 is located in the electrical cabin 110, as shown in fig. 1, and the fire extinguishing apparatus 10 is disposed at a corner of the electrical cabin 110, so as to prevent the disposed fire extinguishing apparatus 10 from affecting the placement of the electrical components in the electrical cabin 110.

As an alternative, the fire extinguishing apparatus 10 provided in the embodiment of the present application employs a heptafluoropropane fire extinguishing apparatus. In a particular arrangement, the capacity of the fire suppression apparatus 10 may be designed according to the space of the electric compartment 110 and the battery compartment 120 and the fire fighting agent used. Illustratively, a 40-foot container using 53.23kg of heptafluoropropane was equipped with a 70L cylinder. Specific data are shown in table 1:

TABLE 1

Heptafluoropropane usage and storage container data table

Design amount (kg) of heptafluoropropane:	51.18
		additional amount (kg) of heptafluoropropane:	2.05
residual amount in heptafluoropropane line (kg):	0.05
		remaining amount of individual container (kg):	2
total required amount (kg) of heptafluoropropane:	53.23
		volume (L) of single storage vessel:	70
single vial of stored drug (kg):	53.23
		filling ratio (kg/m 3):	760.4
number of basic storage containers:	1
		number of replenishment storage containers:	0
total stock (kg):	53.23
		number of reserve storage containers:	0
spare amount (kg) of heptafluoropropane:	0
		actual ejection concentration (%):	9

as can be seen from table 1, when the capacity of the heptafluoropropane fire extinguishing apparatus 10 is specifically selected, the capacity of the selected steel cylinder is greater than the amount of heptafluoropropane calculated according to the design amount of heptafluoropropane, and the capacity of the heptafluoropropane in the steel cylinder is greater than the design amount, so as to ensure that sufficient fire-fighting agent can be provided to ensure the fire-fighting effect.

With continued reference to fig. 1 and 2, the spray heads of the energy storage container fire protection system are used to spray fire suppressant from the fire suppression apparatus 10 into the energy storage container. In the embodiment of the present application, the fire fighting sprinkler is divided into a first fire fighting sprinkler 20 and a second fire fighting sprinkler 30 according to the location of the sprinkler. Illustratively, the sprinkler in the electrical compartment 110 is a first fire hydrant 20 and the sprinkler in the battery compartment 120 is a second fire hydrant 30.

When the first fire hydrant 20 and the second fire sprinkler 30 are specifically provided, the first fire hydrant 20 and the second fire sprinkler 30 are connected to the fire extinguishing apparatus 10 through the pipe 40. As an example, the first fire hydrant 20 and the second fire sprinkler 30 are connected to the fire fighting device 10 through a pipe 40, and the first fire hydrant 20 and the second fire sprinkler 30 may be regarded as being connected in series to the pipe 40. Wherein the electrical spray head is relatively close to the fire suppression apparatus 10 and the battery 130 spray head is relatively far from the fire suppression apparatus 10.

Referring to fig. 1 and 2, it can be seen that the size of the battery compartment 120 is larger than the size of the electrical compartment 110 in order to meet the spray concentration requirement. In the embodiment of the present application, the number of the first fire fighting nozzle 20 is set to be at least one, and the number of the second fire fighting nozzle 30 is set to be plural, wherein the plural number is two or more. It should be understood that the number of different spray heads is set to meet the requirement of space coverage in the whole box 100.

As an example, in the embodiment of the present application, the number of the first fire hydrant 20 is one; the number of the second fire sprinkler 30 is two in a direction away from the electric compartment 110. And two second fire sprinklers 30 are spaced apart in a direction away from electrical compartment 110. It should be understood that in the embodiment of the present application, the first fire fighting nozzle 20 and the second fire fighting nozzle 30 are arranged at a certain interval to ensure that different nozzles spray fire fighting agent to cover different areas. Specifically, the first fire fighting striker 20 is positioned so as to cover the electrical compartment 110. While two second fire sprinkler 30 should cover the entire battery compartment 120.

It should be understood that, in addition to the two second fire-fighting nozzles 30 in the battery compartment 120 and the one first fire-fighting striker 20 in the electrical compartment 110 in the above example, other numbers of nozzles may be provided in the fire-fighting system for the energy storage container according to the embodiment of the present application, depending on the size of the box 100. Illustratively, the number of first fire fighting nozzle 20 is two or three, and the number of second fire fighting nozzle 30 is three or four, etc. in different numbers.

In addition, the arrangement of different numbers of the spray heads is adopted to meet the fire fighting requirements of the electric cabin 110 and the battery cabin 120. The shower nozzle that this application embodiment provided still adopts different specifications to satisfy the demand of fire control. In a specific setting, the equivalent orifice area of any one of the second fire sprinklers 30 is larger than the equivalent orifice area of the first fire control striker 20, wherein the equivalent orifice area is the sprinkler orifice area converted from the standard sprinkler orifice area having a water flow coefficient of 0.98.

As can be seen from fig. 1 and 2, since the second fire sprinkler 30 is connected in series with the first fire hydrant 20 and the second fire sprinkler 30 is far away from the fire extinguishing apparatus 10 than the first fire hydrant 20, the inlet pressure of the first fire hydrant 20 is greater than that of any one of the second fire sprinklers 30, and the fire fighting agent, when transferred to the second fire sprinkler 30, causes the pressure of the second fire sprinkler 30 to be reduced.

To ensure that a greater spray pressure is still available in the battery compartment 120 and that the spray concentration is as desired. The equivalent orifice area of the first fire fighting collision head 20 is smaller, and the equivalent orifice area of the second fire fighting nozzle 30 is larger, so that the fire fighting agent in the pipeline 40 still has enough pressure to flow through to the second fire fighting nozzle 30 after flowing through the first fire fighting collision head 20, and the spraying amount of the fire fighting agent in the battery compartment 120 and the electric compartment 110 can meet the requirement.

It can be seen from the above description that in the embodiment of the present application, a material for fire extinguishing is provided by using one fire extinguishing apparatus 10, and the specifications of the first fire fighting collision head 20 and the first fire fighting collision head 20 are reasonably set, so that even if the first fire fighting collision head 20 and the second fire fighting nozzle 30 adopt the fire extinguishing apparatus 10 to deliver fire fighting agent, the spraying speed of fire fighting gas can be controlled by fire fighting nozzles of different specifications, and the consistency of the spraying solubility of the partitioned fire fighting agent is achieved.

As an example, the equivalent orifice areas of the second plurality of fire sprinklers 30 are the same in a direction away from electrical compartment 110. And the equivalent orifice areas of the plurality of second fire fighting sprinkler heads 30 are each greater than the equivalent orifice area of the first fire fighting striker head 20. Referring to table 2, table 2 illustrates parameter settings using one first fire fighting striker 20 and two second fire fighting sprinkler 30.

TABLE 2

Nozzle parameter table

In table 2, spray head No. 1 and spray head No. 2 are the second fire fighting spray head 30 disposed in the battery compartment 120, and spray head No. 1 is the first fire fighting striker 20 disposed in the electric compartment 110.

The nozzle inlet pressure of the first fire fighting nozzle 20 is 1.3195Mpa, the nozzle inlet pressures of the two second fire fighting nozzles 30 are 1.2723Mpa and 1.2641Mpa, respectively, and the flow rates of the three nozzles are 0.27Kg/s, 2.42Kg/s and 2.42Kg/s, respectively, as illustrated in table 2, thereby ensuring that the fire fighting agent with sufficient concentration can still exist in the battery compartment 120 with a large space. As can be seen from the above description, the second fire sprinkler 30 provided in the embodiment of the present application can use sprinklers of the same size to extinguish fire in the battery compartment 120.

As an example, in the present embodiment, different sized fire sprinkler heads may be used for second fire sprinkler head 30. Specifically, the equivalent aperture area of the second fire fighting nozzle 30 can be gradually increased along the direction away from the electric chamber 110, so that the second fire fighting nozzle 30 farthest from the electric chamber 110 can still or have a greater spraying effect, thereby improving the fire fighting effect.
