Tank liquid mouth 13 for storing up into foam solution in foam liquid tank 1, and leakage fluid dram 14 is for discharging the liquid in foam fluid reservoir. Assembly pulley 6 is assembled on the bottom of foam liquid tank 1, to drive foam liquid tank 1 to be movably walking. Pushing hands 15 setting is beneficial to operator and promotes foam liquid tank 1, hose bed 16 to be used for storing water band 5.
Inline inductor 2 is locked on foam liquid tank 1 top, and it has liquid inlet, water inlet and outlet. First liquid outlet 11 of foam liquid tank 1 connects the liquid inlet of inline inductor 2 by pipeline 7, and this pipeline 7 is sequentially provided with the first check-valves 71 and ball valve 72 along conveying direction.The top of pipeline 7 preferably stretches in foam liquid tank 1 and extends close to foam liquid tank 1 bottom position place. In the first disassembled outlet being connected to inline inductor 2 of foam gun 3, specifically, the outlet of inline inductor 2 is extended with pipeline, and the end of this pipeline is provided with hermaphroditic coupling 9, and the first foam gun 3 is disassembled when not using to be locked on hermaphroditic coupling 9 (as shown in Figure 1).
Preferably, the rear end pipeline of inline inductor 2 is additionally provided with gas-liquid cyclone mixer 8, it is provided with eddy flow baffle plate in gas-liquid cyclone mixer 8, this eddy flow baffle plate is provided with several whirl hole, these several whirl hole surround around the axis of blender and arrange, and are obliquely installed with angle in toward homonymy. Strengthen gas-liquid mixed effect by gas-liquid cyclone mixer 8, be beneficial to foam and produce and the uniform and stable property of foam.
Second foam gun 4 is as in figure 2 it is shown, include the front and back tube tooth interface 41 of assembly and connection, gun body 42 and gun barrel 43 successively. Being provided with hybrid chamber 421 in gun body 42, the sidewall of this gun body 42 is provided with the suction attachment 44 being connected with hybrid chamber 421; Suction attachment 44 connects pipette 49. Pipette 49 is stretched in foam liquid tank 1 by the second liquid outlet 12. The second check-valves 45 it is provided with in pipette 49. Preferably this second check-valves 45 is arranged on the position near its link of the correspondence in pipette 49, to give full play to its effect.
The front end of described hybrid chamber 421 offers water inlet 4211, and the place rearward in this hybrid chamber 421 is equiped with nozzle 46, and this nozzle 46 is to control flow and produce suction function. Gun body 42 is the bearing of foam gun, and tube tooth interface 41 is in order to be connected with water band. Being additionally provided with keying handle 47 and handwheel 48 in gun body 42, opening and closing handle 47 is foam gun cock and imbibition switch, and handwheel 48 is used for controlling foam gun and flows to, and gun barrel 43 is in order to regulate air foam liquid.
This new mobile type fixed froth installation is when fire extinguishing, first foam gun 3 and the second foam gun 4 can use simultaneously, wherein the tube tooth interface (water inlet and outlet) at the two ends of inline inductor 2 is all connected with fire hose 5, the water band Bonding pressure water source of water inlet, the other end of the water band in outlet connects the first foam gun 3, when there being the water being not less than 0.6MPa pressure to flow through the nozzle of inline inductor 2 with significantly high speed, diffusion due to the transverse shifting of jet particle, indoor formation vacuum (negative pressure) of inline inductor 2, then the foam solution in foam liquid tank 1 enters inline inductor 2 by pipeline 7 under the pressure effect of air, mix with press water, it is finally reached a certain proportion of mixed liquor. when having the mixing liquid stream of certain pressure to the first foam gun 3, because the performance of the first foam gun 3 can suck a certain amount of air, foam mixing liquid is made to foam, thus reaching the effect of foam fire-fighting.
