Abstract

The utility model belongs to a forest fire protection tool used for mounting foam fire protection isolation zones in front of forest fire. The utility model has the principle of the main structure that mixed liquid is pressure pumped into a nozzle 5 combined with a plurality of holes through a water cage belt 1 and a nozzle core 2, and the mixed liquid is ejected out from the nozzle 5 combined with a plurality of holes. Moreover, the mixed liquid ejecting flow is dispersed by a dispersing rack 7. The atomized foam liquid is evenly ejected on a foaming net 8. Thus, a great amount of air foam is generated and ejected from the front end of an ejecting barrel 6. The utility model has the advantages that the ejecting amount of the foam can be adjusted, the ejecting range is raised, and the foam is adequate and rich. The utility model is particularly suitable for the occasion of the foam fire protection isolation zone mounted in front of forest fire.

Description

Pump type forest foam generator

The utility model belongs to a kind of forest fire prevention and control utensil.

At present the foam that foam spray produced that uses is abundant inadequately, and because the restriction of range, coefficient of foaming etc. is less compliant in the occasion that the foam fireproof isolation strip is offered in forest fires the place ahead.

The purpose of this utility model provide a kind of can satisfy offer the pump formula forest foam producer that the foam fireproof isolation strip requires in forest fires the place ahead.

Main technical schemes of the present utility model is to comprise water cage band, connect buckle, air inlet end cap, spray tube, foam screen, wherein, water cage band is tightly connected with connecing to buckle, the air inlet end cap is fixedlyed connected with the spray tube, foam screen is fixedly mounted on the front end of spray tube, it is characterized in that sprinkler core is tightly connected with connecing button, and the center of porous combined sprinkler is connected inlet end with bolt and covers, the spray orifice that sprinkler core passes air inlet end cap and porous combined sprinkler is tightly connected, and dividing falls apart is fixedly mounted on the middle part of spraying tube.

Advantage of the present utility model is can regulate the amount of foam ejection and improve its range owing to adopted the porous combined sprinkler; Owing to adopted the dispersion shelf structure, make coefficient of foaming increase, foam abundance, abundant is specially adapted to the occasion that the foam fireproof isolation strip is offered in forest fire the place ahead.

Fig. 1 is assembling of the present utility model and user mode figure.

Fig. 2 is the profile of combined sprinkler.

Fig. 3 is the installation diagram of combined sprinkler etc.

Fig. 4 is for dividing the structure chart that falls apart.

Provide embodiment of the present utility model as follows in conjunction with the accompanying drawings:

The utility model such as Fig. 1, shown in Figure 3, by water cage band 1, connect buckle 2, sprinkler core 3, air inlet end cap 4, porous combined sprinkler 5, spray tube 6, divide fall apart 7, foam screen 8 forms, water cage band 1 and connect and buckle 2 and be tightly connected wherein, sprinkler core 3 with connect button 2 and be tightly connected, the center of porous combined sprinkler 5 is connected on the air inlet end cap 4 with bolt, the spray orifice that sprinkler core 3 passes air inlet end cap 4 and porous combined sprinkler 5 is tightly connected, air inlet end cap 4 is fixedlyed connected with spray tube 6, divide 7 middle parts that are fixedly mounted on spray tube 6 of falling apart, foam screen 8 is fixedly mounted on the front end of spray tube 6.

Porous combined sprinkler 5 as shown in Figure 3, three spray orifices are evenly distributed on the circumference.The diameter of three spray orifices can be respectively φ 6mm, φ 8mm, φ 10mm.

Divide and fall apart 7 as shown in Figure 4, adopt cross structure.

Operation principle of the present utility model is that flow through water cage band 1 and sprinkler core 2 of mixed liquor pumps into porous combined sprinkler 5 with certain pressure, and from 5 ejections of porous combined sprinkler, owing to form certain negative pressure, air is inhaled into from air inlet end cap 4 automatically, the mixed liquor jet falls apart through branch and 7 disperses, the foam solution of atomizing evenly is sprayed on the foam screen 8, thereby produces a large amount of airs, by the front end ejection of spray tube 6.

Claims

1, a kind of pump formula forest foam producer, comprise water cage band, connect buckle, air inlet end cap, spray tube, foam screen, wherein, water cage band is tightly connected with connecing buckle, and the air inlet end cap is fixedlyed connected with the spray tube, and foam screen is fixedly mounted on a front end that sprays tin, it is characterized in that sprinkler core and connect button being tightly connected, the center of porous combined sprinkler is connected inlet end with bolt and covers, and the spray orifice that sprinkler core passes air inlet end cap and porous combined sprinkler is tightly connected, and dividing falls apart is fixedly mounted on the middle part of spraying tube.
