Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, after having the phenomenon of catching fire in the discovery lithium cell group of fire probe (temperature sensing, cigarette etc.), the pump low-speed operation, the fire extinguishing agent in the pump with the fire extinguishing agent storage tank is taken out through the discharging pipe and is looped through the second solenoid valve on the second is taken in charge, the low pressure surge damping valve enters into the third minute pipe, then spray the fire extinguishing agent through the second shower nozzle on the minute pipe in to the lithium cell group and put out a fire, because the existence of low pressure surge damping valve, consequently, can not cause the pressure in the lithium cell group too big, if the interior intensity of a fire of energy storage box enlarges the back, the high-speed operation of pump, the relief valve is run on the pressure top, first solenoid valve through on the first minute pipe, the relief valve, then spray the fire extinguishing agent through first shower nozzle to the energy storage box and put out a fire, realize the second grade operation of putting out a fire, the fire extinguishing effect is good.

Drawings

Fig. 1 is a schematic structural diagram of a fire suppression device for an energy storage tank according to the present invention.

In the figure: 1 energy storage box, 2 lithium cell group, 3 second shower nozzles, 4 second minute pipes, 5 third minute pipes, 6 first shower nozzles, 7 low pressure surge damping valves, 8 second solenoid valves, 9 casings, 10 fire extinguishing agent storage tanks, 11 discharging pipes, 12 pumps, 13 first solenoid valves, 14 relief valves, 15 first minute pipes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, an energy storage box fire suppression device, including energy storage box 1 and casing 9, the internally mounted of casing 9 has fire extinguishing agent storage tank 10, pump 12, the internally mounted of energy storage box 1 has a plurality of lithium cell group 2, be connected with discharging pipe 11 between the export of fire extinguishing agent storage tank 10 and the entry of pump 12, the exit linkage of pump 12 has first minute pipe 15 and second minute pipe 4, install first solenoid valve 13 on the pipe section of first minute pipe 15 in proper order, relief valve 14, first minute pipe 15 runs through the inside of energy storage box 1, be connected with a plurality of first shower nozzle 6 on the first minute pipe 15, install second solenoid valve 8 on the pipe section of second minute pipe 4 in proper order, low pressure regulator valve 7, second minute pipe 4 runs through the inside of energy storage box 1, be connected with a plurality of third minute pipe 5 on the second minute pipe 4, third minute pipe 5 runs through lithium cell group 2 and is connected with second shower nozzle 3, the one end that pump 12 was all welded to first minute pipe 15 and second minute pipe 4, second solenoid valve 8, low pressure regulator valve 7, first pressure regulator valve 13, relief valve 14 all is located the outside of energy storage box 1 and casing 9.
