End is connected, and the other end of overflow valve is connected with main-supply road close to the side of water outlet using another pipeline, the main water supply
The hydraulic turbine is equipped in pipeline, the side of foam pump passes through shaft coupling and clutch to be then connected with the hydraulic turbine using transmission shaft.
For the hydraulic turbine between water inlet end and water outlet, rotation direction is consistent with the rotation direction of foam pump.
The water inlet end position on the main-supply road is higher than water outlet end position.
The clutch, valve one and valve two are connected with external control electronic box.
A kind of mixed method of big flow water-foam solution mixing arrangement has also been devised in the present invention, it is characterised in that：It presses first
Power knob on lower control electronic box is powered to whole device, when needing using foam fire-fighting, presses on control electronic box
Mix button, clutch is closed, and valve one is opened, and foam solution enters foam pump, main-supply by foam solution delivery pipe
The hydraulic turbine in road provides power for foam pump, supports the operating of foam pump, and foam solution is transported to main-supply road
Water outlet makes foam solution be mixed with water, forms mixed liquor, is then sent to fire monitor and is mixed to form foam with air, is disappeared
Anti- big gun sprays；When needing cleaning, when pressing cleaning button, when valve two is opened, flow can clean whole device.
Compared with prior art, the present invention the configuration of the present invention is simple, small, and it is at low cost, it is enterprising trailer can be placed on
Row movement has good mobility for fire processing, and when valve one is opened and closes clutch, can form blebbing
Foam liquid supports the use of fixed froth installation, and when valve one is closed, and valve two is opened, the water in vibration means for main pipe for supplying water road enters bubble
Foam liquid pump pipeline can clean whole device.The work(to supply water merely can be realized in holdback clutch, closure valve one and valve two
Can, realize that occupation mode may be selected in two kinds of functions of an equipment；The internal combustion engine as device power source is eliminated, but uses and disappears
Anti- hydraulic pressure is as power source, using the hybrid mode for having pressure difference so that and not only foam flow can be more than 200L/s to whole device,
And the drawback of the pollution and mobility difference of internal combustion engine generation is prevented.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 be in the present invention F to sectional view.
Specific implementation mode
In conjunction with attached drawing, the invention will be further described.
