Description
Technical field
The present invention relates to fire-fighting equipment technical fields, more specifically to a kind of foam firefighting device.
Background technique
Since the fire water that foam fire fighting system ejects has an a large amount of foam, good attachment isolating power, especially
It puts out a fire suitable for oily substance, therefore also widely configures such fire-fighting system on marine worker ship.As shown in Figure 1, the system is by disappearing
The composition such as anti-pump, valve, foam mixer, foam water cannon and pipeline.After oil fire occurs, valve is opened, starts fire-fighting
Pump, fire water flow through foam mixer from pipeline, and the high power foam liquid in foam mixer storage tank is mixed with fire water, are formed rich
Fire water containing foam, sprays from fire monitor, and a large amount of foam is attached on the oil of kindling, makes oil and air insulated, reaches
The purpose of fire extinguishing.The system core component is foam mixer.However to be all made of principle simple for current foam mixer peculiar to vessel
Venturi tube pattern, there are foam solution mixing it is uneven, flow automatic regulation ability is poor the defects of, to influence extinguishing effect.
Simultaneously also can not constant ratio flow automatic regulation it is less economical so that the waste of foam solution is larger.
Summary of the invention
In order to overcome the deficiencies of the prior art, the present invention provides a kind of foam firefighting device, realizes constant ratio automatic adjustment bubble
The purpose of foam flow quantity avoids the waste of foam solution.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of foam firefighting device, including fire extinguisher canvas hose, driving water pipe, suction line, discharge pipe, impeller, foam pump and bubble
Foam flow container, the driving water pipe are two.One end of two driving water pipes are separately connected the both ends of the fire extinguisher canvas hose, and two
The other end of a driving water pipe connects the impeller, foam pump described in the output axis connection of the impeller, the foam
The inlet of liquid pump connects one end of the suction line, and the other end of the suction line connects the concentrated tank, the foam
The liquid outlet of liquid pump connects one end of the discharge pipe, and the other end of the discharge pipe penetrates the outer wall of the fire extinguisher canvas hose, if
It sets in the inside of the fire extinguisher canvas hose.
Preferably, the discharge pipe is equipped with check-valves.
Preferably, the water inlet end of the fire extinguisher canvas hose is equipped with the connector for connecting fire water pipeline.
Preferably, the suction line and discharge pipe are made of hose.
Preferably, the discharge pipe is penetrated from the outer wall of the water outlet close to the fire extinguisher canvas hose.
Preferably, it is connected between the output shaft of the impeller and the rotary shaft of the foam pump by shaft coupling.
Preferably, the relatively described fire extinguisher canvas hose of driving water pipe is obliquely installed.
The beneficial effects of the present invention are: by driving water pipe to be separately connected fire extinguisher canvas hose and impeller, when work, fire extinguisher canvas hose
In a part of fire water enter driving water pipe driving impeller rotation, impeller drives the impeller rotation of foam pump, and passes through suction
Enter pipe and suck foam solution from concentrated tank, then foam solution is injected by fire extinguisher canvas hose and fire water mixing by discharge pipe.Therefore
Know that the revolving speed of foam pump is directly proportional to the flow of fire water, and the discharge capacity of foam pump is directly proportional to its revolving speed, so
The injection flow and fire water flow of foam solution are directly proportional, to realize the mesh of constant ratio automatic adjustment foam flow quantity
, avoid the waste of foam solution.The configuration of the present invention is simple, using effect is good, use easy to spread.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Please refer to attached drawing 2-3, a kind of foam firefighting device of the present embodiment, including fire extinguisher canvas hose 1, driving water pipe 2, suction line
3, discharge pipe 4, impeller 5, foam pump 6 and concentrated tank 7, the driving water pipe 2 are two, two driving water pipes 2
One end is separately connected the both ends of the fire extinguisher canvas hose 1, and the other end of two driving water pipes 2 connects the impeller 5, the leaf
Foam pump 6 described in the output axis connection of wheel 5, the inlet of the foam pump 6 connects one end of the suction line 3, described
The other end of suction line 3 connects the concentrated tank 7, and the liquid outlet of the foam pump 6 connects one end of the discharge pipe 4,
The other end of the discharge pipe 4 penetrates the outer wall of the fire extinguisher canvas hose 1, and the inside of the fire extinguisher canvas hose 1 is arranged in.
Foam firefighting device based on above-mentioned technical characteristic, by driving water pipe 2 to be separately connected fire extinguisher canvas hose 1 and impeller 5, work
When making, a part of fire water in fire extinguisher canvas hose 1 enters driving water pipe 2 and impeller 5 is driven to rotate, and impeller drives foam pump 6
Impeller rotation, and foam solution is sucked from concentrated tank 7 by suction line 3, then foam solution is injected by fire water by discharge pipe 4
Pipe 1 and fire water mixing.It may thus be appreciated that the revolving speed of foam pump 6 is directly proportional to the flow of fire water, and the discharge capacity of foam pump 6
It is again directly proportional to its revolving speed, so the injection flow and fire water flow of foam solution are directly proportional, to realize constant ratio certainly

6 draw the foam solution in the concentrated tank 7.
In the present embodiment, the discharge pipe 4 is equipped with check-valves 8.By the way that the check-valves 8 is arranged, foam solution ensure that
It will not be flowed to the direction of concentrated tank 7 with the mixed liquor of fire water, avoid mixed liquor and flow into the pollution of concentrated tank 7 bubble
Foam liquid.
In the present embodiment, the water inlet end 11 of the fire extinguisher canvas hose 1 is equipped with the connector 9 for connecting fire water pipeline.Pass through
The connector 9 is set, and the foam firefighting device is connected on fire protection pipeline by fast and easy.
In the present embodiment, the suction line 3 and discharge pipe 4 are made of hose.Using hose make the suction line 3 and
Discharge pipe 4, it is easy to manufacture and install.
In the present embodiment, the discharge pipe 4 is penetrated from the outer wall of the water outlet 12 close to the fire extinguisher canvas hose 1.The leaf
It is connected between the output shaft of wheel 5 and the rotary shaft of the foam pump 6 by shaft coupling 10.
In the present embodiment, the relatively described fire extinguisher canvas hose 1 of driving water pipe 2 is obliquely installed.Since the impeller 5 is to pass through
A part of fire water in the fire extinguisher canvas hose 1 drives into the driving water pipe 2, so by the opposite institute of the driving water pipe 2
It states fire extinguisher canvas hose 1 to be obliquely installed, fire water can be made preferably to drive the impeller 5, improve drive efficiency.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
