Description
Technical field
The invention belongs to fire-fighting robot field, specifically a kind of middle explosion-proof fire-fighting foams big gun of low power.
Background technique
Foam monitor in fire-fighting domain for fire extinguishing is typically all low-expansion foam big gun, it can put out a fire at a distance, put out a fire
In play an important role.Frothing percentage can be expanded to 40-50 times of low-expansion foam big gun by medium expansion monitor, and extinguishing property is more
It is superior.But in practical applications, since medium expansion foam is light-weight, itself jet power is not strong, medium expansion foam cannot be ejected into
At a distance, it is difficult to have the function that in fire extinguishing far and near while put out a fire, and existing medium expansion monitor equipment does not have explosion-proof function
Can, it is not suitable in hazardous applications application.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of middle explosion-proof fire-fighting foams big guns of low power.
The technical solution adopted by the present invention is that: a kind of middle explosion-proof fire-fighting foams big gun of low power, the explosion-proof fire-fighting foams big gun include:
Foam web, U-shaped bend pipe, explosion-proof horizontal rotation mechanism, medium expansion foam cylinder, bent pipe bracket, rotary shaft rack, explosion-proof pitching turn-around machine
Structure, low expansion foam jet pipe, medium expansion foam injection apparatus, monitor body threeway, motor, big gun neck assembly, retainer plate, low expansion foam are mixed
Close liquid spray head, gun tube retainer plate and medium expansion foam nozzle.
The explosion-proof horizontal rotation mechanism connects U-shaped bend pipe, U by the threeway of flanged joint monitor body, the both ends of monitor body threeway
The other end of type bend pipe connects big gun neck assembly；Big gun neck assembly is separately connected low expansion foam jet pipe and medium expansion foam injection apparatus.
One end of explosion-proof pitching swing mechanism connects monitor body threeway, and the other end connects big gun neck assembly, for controlling foam monitor pitching injection
Angle.
Low power explosion-proof type fire-fighting foams big gun in this, monitor body are supplied water using double u-tube, and structure novel effectively raises whole
Effect is flowed, low power big gun head uses general water cannon appearance, and inner cavity uses improved foaming cavity design；Medium expansion foam nozzle is using double
Water outlet is concentrated on road, and medium expansion foam nozzle is provided with the disturbing flow device for increasing coefficient of foaming, is used before medium expansion foam nozzle double-deck flat
The design of face steel wire, substantially increases frostproof froth n jeting effect and distance.
The beneficial effects of the present invention are: the middle explosion-proof fire-fighting foams big gun monitor body of low power is supplied water using double u-tube, it is effective to improve
Rectification effect；Since low-expansion foam big gun uses improved foam chamber, disturbing flow device is increased in medium expansion foam nozzle faucet,
Medium multiple foams cylinder using double-layer wire web frame, substantially increases the spray distance of foam.It the horizontal rotation of foam monitor and faces upward
Swing mechanism of bowing uses Explosion-proof Design, greatly improves the application of equipment.
Detailed description of the invention
Fig. 1 is the explosion-proof fire-fighting foams big gun main view of middle low power.
Fig. 2 is the explosion-proof fire-fighting foams big gun top view of middle low power.
Fig. 3 is the explosion-proof fire-fighting foams big gun side view of middle low power.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, the explosion-proof fire-fighting foams big gun of a kind of middle low power, by foam web (1), U-shaped bend pipe (2), explosion-proof water
It is flat swing mechanism (3), medium expansion foam cylinder (4), bent pipe bracket (5), rotary shaft rack (6), explosion-proof pitching swing mechanism (7), low
Expansion of foam jet pipe (8), medium expansion foam injection apparatus (9), monitor body threeway (10), motor (11), big gun neck assembly (12), retainer plate
(13), low expansion foam mixed liquor spray head (14), gun tube retainer plate (15) and medium expansion foam nozzle (16) composition.
The motor (11) is connected with one end of explosion-proof horizontal rotation mechanism (3), explosion-proof horizontal rotation mechanism (3) it is another
End connection monitor body threeway (10), monitor body threeway (10) both ends are separately connected a U-shaped bend pipe (2), the other end of U-shaped bend pipe (2)
It connects big gun neck assembly (12), big gun neck assembly (12) is separately connected low expansion foam jet pipe (8) and medium expansion foam injection apparatus (9).
One end of the explosion-proof pitching swing mechanism (7) connects monitor body threeway (10), and the other end is total by rotary shaft rack (6) connection big gun neck
At (12), to control the pitching spray angle of medium expansion foam cylinder (4).
2 medium expansion foam nozzles (16) are separately mounted to 2 exits of medium expansion foam injection apparatus (9), medium expansion foam
There is disturbing flow device in nozzle (16), to increase coefficient of foaming.Medium expansion foam cylinder (4) passes through bent pipe bracket (5) and retainer plate
(13) it is fixed on medium expansion foam injection apparatus (9), and is screwed.Foam web (1) is fixed in medium expansion foam cylinder (4)
Side, foam water mixed liquid impinge upon on foam web (1) after medium expansion foam nozzle (16) spray, and refinement water column reaches better hair
Steep effect.Low expansion foam mixed liquor spray head (14) is mounted on the exit of low expansion foam jet pipe (8).The gun tube retainer plate
(15) it is mounted on medium expansion foam cylinder (4) inside, for the reinforcing to medium expansion foam cylinder (4).
Foam web (1) uses clad steel silk screen, is fixed the clad steel silk screen of foam web (1) by gun tube retainer plate (15)
On the inside of medium expansion foam cylinder (4), medium multiple coefficient of foaming can be increased using clad steel silk screen design.
Explosion-proof horizontal rotation mechanism (3) and explosion-proof pitching swing mechanism (7) are all made of blast resistance construction design.
The working principle of the invention is: supplying foam water mixed liquid, explosion-proof level by fire-fighting robot ontology water inlet pipe
Swing mechanism adjusts horizontal position spray angle, and pitching anti-explosion adjusting mechanism adjusts upright position spray angle, foam water mixing
Liquid passes through horizontal turbine to monitor body threeway by water inlet pipe, then separately flows into the U-shaped bend pipe in both sides, the weight after U-shaped bend pipe
It newly is imported into big gun neck, the adjustable upper lower angle of big gun neck, big gun neck is divided into two-way medium multiple water outlet again and low power counts water all the way
Mouthful, big gun neck low power counts mouth of a river connection low power number nozzle and low expansion foam bucket, foam water mixed liquid are sprayed from nozzle, big gun neck
Medium multiple water outlet connects two medium multiple nozzles, and disturbing flow device is equipped in medium multiple nozzle, and foam water mixed liquor passes through flow-disturbing
The online face of double-layer wire of medium multiple foaming cylinder is ejected into after device from nozzle, completes the course of injection of medium multiple, low power number
Feature is that spray distance is remote, but foaming effect is poor, and medium multiple is opposite good with foaming effect for low power number, but spray distance is close.
The method combined using medium multiple and low power number can play the strong point of the two, obtain preferable extinguishing effect.
