[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 4 A centralized pump group driven fire suppression device comprises a foaming agent storage tank 1 and a mixing foaming tank 2, wherein the foaming agent storage tank 1 is connected to the mixing foaming tank 2 through an electromagnetic valve 3, a driving motor 4 is arranged above the foaming agent storage tank 1 and the mixing foaming tank 2, the driving motor 4 is connected to a gas-liquid dual-purpose pump 5 through a coupling transmission, a mixing agitator 7 is arranged in the mixing foaming tank 2, a spiral agitator 8 is fixedly connected to one side of the mixing agitator 7, the mixing agitator 7 and the spiral agitator 8 are fixedly connected to a hollow stirring shaft 9, a large pulley 10 is fixedly connected to one end of the hollow stirring shaft 9, an eccentric shaft 501 is arranged in the gas-liquid dual-purpose pump 5, the eccentric shaft 501 is connected to the main shaft of the driving motor 4 through a coupling, the other end of the eccentric shaft 501 is connected to a small pulley 6 through a keyway, the small pulley 6 and the large pulley 10 are connected through a belt transmission, so that the driving motor 4 can drive the mixing agitator 7 and the spiral agitator 8 to rotate while driving the gas-liquid dual-purpose pump 5 to work;

[0024] like Figure 3 As shown, the water injection piston pump 502 includes a first piston 5021, and the eccentric shaft 501 is transmission-connected to the first piston 5021 through a connecting rod. A sealed first cylinder body 5022 is arranged outside the first piston 5021, a water inlet pipe 5023 is arranged on the first cylinder body 5022, and a pressurized water injection pipe 5024 is arranged on the first cylinder body 5022. A one-way valve is arranged at the connection between the water inlet pipe 5023 and the pressurized water injection pipe 5024 and the first cylinder body 5022. The water inlet pipe 5023 is connected to a water source, and the pressurized water injection pipe 5024 is connected to the mixing foaming tank 2. When such a centralized pump group-driven fire suppression device is working, the driving motor 4 will drive the eccentric shaft 501 of the gas-liquid dual-purpose pump 5 to rotate, thereby driving the first piston 5021 in the water injection piston pump 502 to reciprocate rapidly through the connecting rod, and then, with the cooperation of the one-way valve, water is quickly drawn from the water source and pressurized and injected into the mixing foaming tank 2.

[0025] The gas injection piston pump 503 includes a second piston 5031, and the eccentric shaft 501 is transmission-connected to the second piston 5031 through a connecting rod. A sealed second cylinder body 5032 is arranged outside the second piston 5031, and a dust-proof air inlet cover 5033 and a pressurized air injection pipe 5034 are arranged on the second cylinder body 5032.

[0026] like Figure 4 As shown, the hollow stirring shaft 9 is provided with dense filter discharge holes 11, and the filter discharge holes 11 are located on the outside of the mixing agitator 7 and the spiral agitator 8, so that the mixing agitator 7 rotates and stirs quickly to fully mix water, air and foaming agent into foam, and the spiral agitator 8 can transport the foam to the filter discharge holes 11 for easy discharge.

[0027] Working principle: When a fire occurs, a centralized pump group-driven fire suppression device is started, and the driving motor 4 drives the eccentric shaft 501 of the gas-liquid dual-purpose pump 5 to rotate, thereby driving the first piston 5021 and the second piston 5031 in the water injection piston pump 502 and the gas injection piston pump 503 to reciprocate rapidly through the connecting rod, so that the water injection piston pump 502 quickly draws water from the water source and pressurizes it into the mixed foaming tank 2, and the gas injection piston pump 503 also quickly draws air and injects it into the mixed foaming tank 2, and at the same time, the liquid foaming agent stored in the foaming agent storage tank 1 is also pumped or pushed by pressure. The water, air and foaming agent are fully mixed into foam. At the same time, the rotation of the spiral agitator 8 will also transport the foam to the left end of the mixing foaming tank 2. At the same time, under the continuous pressure of the water injection piston pump 502 and the air injection piston pump 503, the pressure in the mixing foaming tank 2 rises, thereby pressing the foam out from the filter discharge hole 11 on the hollow stirring shaft 9, and then transported to the spray pipe through the hollow stirring shaft 9 and the foam discharge pipe 13 for spraying to extinguish the fire.
