Description

High pressure extinguishing gun for fire extinguishing

The present invention relates to a fire extinguishing gun, and more specifically, it is possible to efficiently extinguish forest fires and general fires by spraying a small amount of water at high pressure. It relates to a high-pressure fire extinguishing gun for fire extinguishing that enables efficient fire extinguishing by water channels and that can be applied in various ways to spray fire extinguishing water in response to various fires.

In general, in the event of a fire, it is possible to extinguish the fire by reporting to the fire department and using an indoor fire hydrant, but most of the general public prioritizes evacuation, so it is difficult to extinguish the initial extinguishing, and if a little delay occurs, it can spread to a large fire. .

In addition, if a fire occurs on a road or an island mountainous area without firefighting facilities, a fire engine or a forest fire extinguishing vehicle will mobilize to extinguish the fire.In this case, the fire must be extinguished with limited extinguishing water. It is difficult.

In particular, in the case of forest fires, fire areas are widely distributed, and fires must be extinguished with limited fire extinguishing water, and since fire engines or fire extinguishing vehicles cannot climb to the mountain, a long thin high pressure hose is required, and a small amount of fire extinguishing water is required. It must be used effectively to extinguish the fire.

However, while forest fires are on an increasing trend, fire suppression equipment used to suppress forest fires is still insufficiently developed, and moreover, hundreds of forest fire fighters have used pesticide spraying guns or car wash guns for use in forest fire fires. As a result, effective fire extinguishing activities are difficult, and moreover, due to the high-pressure waterproofing pressure sent from the forest fire extinguishing vehicle under the mountain, frequent breakdowns occur at the forest fire fire site, and the safety of the forest fire extinguisher cannot be guaranteed.

In the case of pesticide spray gun, it is a medium pressure product used at 20 ~ 40bar, and is not suitable for high pressure use.The product is made for horizontal or upward radiation. Therefore, wrist pain may occur when used for a long time, and it is difficult and inconvenient to radiate in an accurate pattern because the pattern control handle is controlled by a swing method of the front and back and does not provide a stable grip according to the radiation direction.

In the case of a car wash gun, it is developed for car washing and can be applied at high pressure, but the radiation flow rate is small, the radiation distance is short, and the spray pattern is limited.

In other words, since it is for washing and washing, it is easy for close injection, but the pattern control function is located at the end of the spray gun, so it is difficult to quickly control the pattern. When adjusting the pattern, for the safety of the user, the spray must be stopped and then adjusted. Is not suitable for fire suppression because it is injected in a flat fan shape.

It is necessary to develop a high-pressure fire extinguishing gun that can effectively use fire suppression by improving the above inconveniences and problems.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

The high-pressure fire extinguishing gun for fire extinguishing of the present invention, which extinguishes a fire by spraying a small amount of water provided from a high-pressure hose at high pressure, as shown in Figs. 1 to 6, the supply body 100, the first connector 200 ), the control valve 300, the second connector 500, the swirl 600, and the injection nozzle 400 are sequentially connected to spray fire extinguishing water in at least three modes.

As shown in FIG. 2, the supply body 100 may regulate fire extinguishing water provided by a high-pressure hose and supply it to the first connector 200 connected to the end according to the user's selection.

As described above, the supply body 100 has a hose connector 120 connected to the high pressure hose to the case 110 having the main handle 111 for gripping the user at the end, the supply pipe 130, the supply valve ( 140) may be sequentially connected therein.

In the case of the hose connector 120, it is preferable to be provided at the end of the main handle 111, and the connection of a high-pressure hose having a high-pressure connector for connecting to supply normal high-pressure gas or high-pressure water can be made detachably. .

The supply pipe 130 is interconnected to supply fire extinguishing water from the hose connector 120 to the first connector 200, and may be provided inside the case 110.

In particular, the supply pipe 130 is preferably provided inside the main handle 111 of the case 110.

In addition, the supply valve 140 has a trigger 141 connected between the supply pipe 130 and the first connection pipe 200 to selectively interrupt or switch the supply of fire extinguishing water by a user.

A general pesticide spray gun or a car wash gun may have both the main handle 111 and the supply valve 140 of the same type, and supply when the user grips the main handle 111 with one hand and pulls the trigger 141 with a finger. By opening the valve 140, the fire extinguishing water provided to the supply valve 140 along the supply pipe 130 through a high-pressure hose may be selectively supplied to the first connection pipe 200.

Meanwhile, the first connection pipe 200 may be connected to the supply body 100 in front of the pipe.

At this time, the outer circumference of the first connector 200 is finished with a rubber or plastic molded product formed with a plurality of grooves along the length direction, and when gripped with the opposite hand, it can be safely gripped with a sense of thickness, and cold air Can be blocked.

Next, the control valve 300 is provided connected to the end of the first connector 200 to adjust the spray pattern of the fire extinguishing water supplied along the first connector 200 according to the user's selection.

As shown in FIG. 3, the second connection pipe 500 is pipe-connected to the outlet 312 of the control valve 300, and the extinguishing water passing through the control valve 300 is at an end of the second connection pipe 500. It moves along the second connector 500 and is sprayed through the spray nozzle 400 at the end.

At this time, the second connection pipe 500 is made of a double pipe including a direct flow path 510 formed in the center so that the supplied fire extinguishing water is discharged in a straight line, and an injection flow path 520 formed around the outer circumference of the direct flow path 510. I can.

On the other hand, the control valve 300 includes an inlet 311 to which the first connector 200 is connected and an outlet 312 to which the second connector 500 is connected, and a valve housing 310 formed therethrough. The joint is connected.

In addition, a control hole 313 through which a control cock 320 capable of adjusting a pattern in which fire extinguishing water is sprayed may be formed in the center of the valve housing 310.

The adjustment cock 320 may be rotatably accommodated or provided through the adjustment hole 313.

As shown in FIGS. 4 to 6, the adjustment cock 320 has a cylindrical shape, and a direct water hole 321 is formed horizontally at the center, and a branch hole meeting at the center in a 50° angle direction with respect to the direct water hole 321 ( 323) can be formed.

That is, it is preferable that the direct water hole 321 and the branch hole 323 formed in the adjustment cock 320 are formed in a'y' shape corresponding to the cross section of the adjustment cock 320.

In addition, at one end of the adjustment cock 320, the adjustment cock 320 is rotated according to the user's selection and extended to a predetermined length so that the fire extinguishing water can pass through various patterns. An auxiliary handle 330 may be further provided.

Therefore, when the user grips the auxiliary handle 330 and rotates the auxiliary handle 330, the direct water hole 321 and the branch hole 323 are formed through the rotation of the adjustment cock 320 that is rotated together. According to the matching of the inlet 311 and the outlet 312 of 310, the supplied fire extinguishing water can be discharged in various patterns.

In the case of the control valve 300, a state discharged in various patterns according to the rotation of the control cock 320 may be implemented in each injection mode.

As a method of operating the control valve 300, the auxiliary handle 330 changes the pattern while rotating in the axial direction perpendicular to the injection direction to reduce recoil and secure the safety of the user, so that stable gripping and pattern control can be easily performed even at high pressure. When the pattern is changed, the pattern can be freely changed without stopping the spinning in a high pressure state by forming a mixed flow path that intersects the two discharge flow paths.

The control valve 300 may provide a jet injection mode, a mixed injection mode, and a mist injection mode function capable of effectively injecting the fire extinguishing water provided through the high-pressure hose according to each mode.

As shown in FIG. 1, a mode display 325 for changing a mode to a jet injection mode, a mist injection mode, and a mixed injection mode may be formed on an upper portion of the control valve 300.

The control valve 300 has one direct water hole 321 passing through the center and a branch hole 323 at an angle of 50° meeting the center of the direct water hole 321.

As shown in FIG. 4, in the case of the jet injection mode, when the direct water hole 321 of the control valve 300 coincides with the internal direct oil passage at the center of the outlet side, the fire extinguishing water supplied along the direct oil passage 510 is swirled 600 It passes through the through hole 620 in a straight line and is radiated in a straight line toward the front through the injection port 410 of the injection nozzle 400.

As shown in Figure 5, in the case of the mist injection mode, when the direct water hole 321 of the control valve 300 is rotated by 50° in a counterclockwise direction, it is connected to the outlet side external injection passage 520 to open the external injection passage 520. Passing through the vane 610 in which the inclined flow path of the residence swirl 600 is formed, while passing through the injection port 410 while rapidly rotating along the inclined surface formed in the chamber of the injection nozzle 400, mist is formed in a form having an injection angle. Is radiated.

Formed in a cup shape by assembling the injection nozzle 400 at the end of the second connector 500, the air inlet hole 531 is formed through the periphery, and the foam sprayed through the injection nozzle 400-fire extinguishing It may include a mixing space 530 for mixing the drug and air introduced through the air inlet hole 531.

At this time, air is introduced while rotating through the air inlet hole 531 formed in a spiral shape at the end of the injection passage 520, and the air inflow rotation direction should be the same as the rotation direction of the vane 610 to ensure smooth air inflow and radiation distance. You can see an increasing synergy effect.

In other words, in the case of fire extinguishing water supplied along the injection passage 520 by supplying fire extinguishing water along the injection passage 520 of the second connection pipe 500 through the adjustment of the control valve 300, the swirl 600 When the fire extinguishing water is rapidly rotated on the inclined surface of the chamber 420 of the injection nozzle 400 while passing through the vane 610, it spreads toward the front when it is injected through the injection port 410 and sprays with a mist. I can.

At this time, the mist spraying angle is preferably in the range of 60° because the excessive radiation angle may cause loss of spray characteristics due to the influence of the invalid radiation distance and external wind.

In the end space of the second connector 500, the fire extinguishing water sprayed at 60° blocks the air flowing into the front, and induces air inflow through the air inlet hole 531 formed around the second connector 500. The atomization phenomenon of the sprayed fire extinguishing water can be maximized.

As shown in FIG. 6, in the mixed injection mode, mixed injection is performed in a section in which the direct water hole 321 of the control valve 300 connects the direct flow passage 510 and the injection passage 520 of the outlet 312 at the same time.

In other words, when all of the fire extinguishing water is supplied along the direct fuel passage 510 and the injection passage 520 of the second connector 500 through the adjustment of the control valve 300, In the case of fire extinguishing water, it passes straight through the through hole 620 of the swirl 600, and in the case of fire extinguishing water supplied along the injection passage 520, the fire extinguishing water that rotates while passing through the vane 610 of the swirl 600 is sprayed. The nozzle 400 is mixed while rotating at the center and inclined surface of the chamber 420 to generate a pulsation, and when sprayed through the injection port 410, the mist spraying and the jet spraying can be performed simultaneously while spreading in a range of 60° toward the front. .

At this time, when the foam (foaming agent) is mixed with the provided fire extinguishing water and sprayed with a foam (foam-extinguishing agent), it has a foam-mixing spray function of forming bubbles.

On the other hand, in the case of foam-mixed injection, if foam-extinguishing agents are mixed with air to form bubbles and radiate to increase fire extinguishing capacity or to extinguish oil fires, suffocation effects and re-ignition suppression effects are achieved along with cooling effects. You can increase it.

Therefore, in the case of the foam-extinguishing agent mixing function, the straight foam that quickly passed through the direct flow path 510 in the mixed spraying mode-the foam that rotates while passing through the vane 610 of the swirl 600-the fire extinguishing agent spray nozzle It may be mixed in the chamber 420 of 400 and sprayed through the injection hole 410.

At this time, a pulsation occurs due to a rapid change in flow rate and flow rate in the chamber 420, and foam-extinguishing agent foaming may be amplified.

In order to make a structure in which the sprayed foam-extinguishing agent is mixed with air, the spray nozzle 400 is assembled inward at the end of the second connector 500 to form a cup, and at the end of the second connector 500 The air inlet hole 531 is formed inclined along the periphery, and the size and number of the holes, and the depth of the cup are determined in consideration of the injection angle and the radiation flow rate.

At this time, in order to strongly induce air inflow into the air inflow hole 531, the injection angle should be an angle capable of blocking the air flowing forward by blocking the end of the second connector.

In addition, when air is introduced while rotating through the air inlet hole 531, the direction of rotation of air inlet should be the same as the direction of rotation of the swirl 600, so that smooth air inlet and a synergistic effect of increasing the radiation distance can be seen.

In the mixing injection mode of the control valve 300, the foam-extinguishing agent flowing into the direct flow passage 510 at a high speed and the foam-extinguishing agent flowing into the injection passage 520 are mixed in the chamber of the injection nozzle 400. As a result, a pulsation is generated and an injection angle is formed through the injection hole 410, and the air is injected from the rear through the cup at the end of the injection channel 520 and injected from the center of the injection hole 410 forward. In the hole 531, air is rapidly and strongly sucked in and mixed with a foam-extinguishing agent to create a foam.

At this time, even after spinning, pulsation is periodically generated, and irregular turbulence is formed to amplify the generation of bubbles (foams).

That is, the foam-extinguishing agent supplied along the direct flow path 510 and the foam-extinguishing agent supplied along the injection flow path 520 pass through the through-hole 620 and the vane 610 of the swirl 600 to spray nozzle While mixing in the chamber 420 of 400, pulsation is generated, and mist injection and jet injection are simultaneously injected through the injection hole 410 and flow into the interior of the mixing space 530 formed at the end of the second connector 500 The air inlet hole 531 is centered along the end direction from the outer surface of the second connector 500 so that the generation of bubbles is amplified by irregular turbulence as the air is strongly sucked and pulsation is periodically generated after radiation. At the same time as the oblique penetration, it may be formed through the helical direction along the circumferential direction.

At this time, it is preferable that the air inflow hole 531 penetrates in a helical direction along the circumferential direction and penetrates at an inclined angle in the range of 40 to 50° in the center direction, and most suitably may be inclined at an angle of 45°. .

The present invention can perform mist spraying, jet spraying, and mixed spraying according to the mode selection, and foam-extinguishing agents are provided without the need for additional additional structures to form and spray foams in the mixed spraying mode. By additionally possessing the foam-mixing spray function that can be used, it can respond organically to various fire situations in an urgent fire site.

In other words, it is possible to respond organically to various fire situations in an urgent fire site by additionally possessing a foam-mixed spray function that can form and spray foam only by changing the mode and provided foam-fire extinguishing agent without changing the structure.

In addition, it is easy to use for a long time in a mountainous area or in a narrow space, and it is easy to carry, light, and durable.

Therefore, the present invention has the effect of lowering the product cost due to its simple structure while additionally providing a foam-mixing spraying function.

And, in order to adjust in the pattern of the mode selected by the user, a guide groove is formed in the valve housing 310 so that the rotation of the adjustment cock 320 can be made within a set angle of 50°, and the adjustment cock ( 320) A fixing bolt protrudes at the lower end and may be provided to rotate within the guide groove.

The front end of the spray nozzle 400 of the second connector 500 includes a direct flow path 510 and a swirl 600 connected to the spray path 520.

A through hole 620 connected to a direct flow path is formed in the center of the swirl 600, and a plurality of vanes 610 having an inclined flow path are formed around the circumference, so that the fire extinguishing water can be rotated by the discharged pressure.

As shown in FIG. 7, a notification means may be added to the fire extinguishing gun configured as described above to detect residual heat (embers) remaining after suppression and to notify the user.

That is, a heat sensor 700 for detecting whether there is residual heat in the front after fire suppression may be further provided at any one part of the second connector 500.

The thermal sensor 700 may additionally include a communication module 710 and an alarm lamp 720.

The heat sensor 700 includes an alarm lamp 720 notifying the user with light or a buzzer so that the user can recognize residual heat detected by the heat sensor 700, and residual heat or flame detected through the heat sensor 700. It may include a communication module 710 for transmitting a signal to share data with the control center.

Due to the nature of wildfire fires, it is difficult to visually check that there are remaining fires or embers under fallen leaves, and if re-fire occurs, enormous losses occur.Therefore, additional personnel to monitor the remaining fires are being added. It must be thoroughly removed.

Therefore, by installing a heat sensor 700, the temperature after suppression is automatically detected, and when the temperature is higher than a certain temperature, the alarm lamp 720 is turned on and notified, and a buzzer is added to inform the user with a sound to check the remaining light that is not visible to the user. It can be removed, and real-time data on fire and embers detected through the heat sensor 700 can be shared with the control center through the communication module 710 and an app on the smartphone, and fire suppression based on the accumulated data. Can help you build your strategy.

In addition, it provides a function to extinguish a fire immediately by accurately finding a fire point in a heavy smoke or dark area.

By providing the present invention configured as described above, a small amount of water can be sprayed at high pressure to quickly extinguish not only the fire extinguishing but also the initial fire of general fires and controllable oil fires.
