Description

Collision-type atomizing fire-fighting window

The present invention relates to a fire extinguisher window, and more particularly, to facilitate fire suppression at various types of fire sites by simply changing the spraying form of firefighting water, as well as fine atomizing particles by performing fine atomization by a collision method. It relates to a collision-type fine spray fire extinguisher window that expands the delivery range of the fire extinguisher to increase fire suppression performance, and prevents rapid recoil at the initial stage of spraying fire water, so that it can be safely used.

When a fire occurs in residential and industrial facilities, it can lead to enormous human and material damage.

Accordingly, a number of related persons are paying attention to fire prevention and fire suppression, and various firefighting facilities are being operated for fire prevention and fire suppression.

On the other hand, a fire hose is provided in an indoor fire hydrant and a fire engine, and the fire water from the water hydrant and the tank is simply transferred to the vicinity of the fire site through the fire hose.

In addition, a fire hose is provided at the tip of the fire hose, and the fire water transferred through the fire hose is sprayed to the source of the fire through the fire pipe window.

Therefore, the fire extinguishing is carried out according to the fire water sprayed through the fire pipe window reaching the source of the fire.

However, since the general fire-fighting window sprayed only the water stream in the form of a stream, it was difficult to use it in a situation other than a general fire, for example, an oil fire.

Therefore, in the event of an oil fire, halon or carbon dioxide gas is sprayed instead of water for firefighting to extinguish the fire.

However, halon or carbon dioxide gas has a problem in that it is not only harmful to the human body but also causes environmental damage.

In order to solve this problem, as disclosed in Korean Patent Application Laid-Open No. 10-2007-0103795, etc., a fire pipe window (hereinafter, 'fine spray fire pipe window') for finely spraying fire fighting water has been proposed.

However, since the conventional fine spray fire pipe window uses a high pressure of 80 bar or more, a system equipped with a separate high-pressure pump and piping is required, so there is a significant problem in cost.

In addition, the conventional fine spray fire pipe window has a limited spraying range of water for firefighting, that is, a short spraying distance and a narrow spraying angle, making it difficult to respond to large-scale fires with a wide fire range.

In addition, as the conventional fine spray fire tube window sprays water that is not drinking water as fire water, that is, water containing foreign substances, the fine spray sphere is frequently clogged with foreign substances, making it difficult to extinguish a fire.

In order to solve the problem of such a conventional fine spray fire extinguisher window, the present applicant has proposed the Republic of Korea Patent Registration No. 10-1902124 'hybrid atomized fire extinguisher window'.

The 'hybrid unsprayed firefighter window' is a bar that simply switches the type of spraying water for firefighting, so that fire suppression can be made smoothly at various types of fire sites, and in particular, a cylindrical wire filter is installed on the inner surface of the pattern control tube due to direct reasons. When installed, as foreign substances contained in the firefighting water were filtered out by the wire filter, clogging of the fine spray nozzle could be prevented.

However, the 'hybrid atomized fireman's window' had a problem in that the fire suppression performance was lowered due to the relatively short firefighting water spraying distance. As a result, there was a problem that the penetration power to the flame was decreased and the fire suppression performance was lowered. As the system was installed, the structure became complicated and cost was increased, and there was a problem in that productivity was lowered.

In addition, in the collision-type fine spray fire pipe window according to the present invention, since the fire fighting water is finely sprayed by the collision method, the fire fighting water delivery range is expanded as well as the penetration of the flame becomes smoother, so that the fire suppression is more smooth can do.

In addition, in the collision-type fine spray fire pipe window according to the present invention, since the fine atomization of firefighting water is made by the collision method, it is possible to reduce the cost and inconvenience of preparing and installing a turning member for fine atomization of firefighting water. productivity can be increased.

In addition, since the collision-type fine spray fire pipe window according to the present invention can be finely sprayed through the injection head, the rapid recoil is prevented at the initial stage of the fire fighting water injection by allowing the fine atomization to be performed at the initial stage of the fire fighting water injection. can

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in Figs. 1 and 2, the collision-type fine atomizing fire pipe window (A) according to the present invention includes a main body (10); fixed tube 20; deflector 30; rotating tube 40; and a jet head 50;

In the main body 10 of the present invention, an inlet 11 through which firefighting water flows is formed at one end in the longitudinal direction, and an outlet 12 through which firefighting water flowing in through the inlet 11 flows out is formed at the other end in the longitudinal direction.

Therefore, the fire-fighting water flowing in through the inlet 11 and then flowing out through the outlet 12 passes through the fixed pipe 20 to the injection head 50 so that the fire-fighting water is sprayed.

At this time, the main body 10 includes a ball valve 13 for controlling the flow of firefighting water between the inlet 11 and the outlet 12; and a lever 14 for opening and closing by rotating the ball valve 13; as the ball valve 13 is opened by the operation of the lever 14, the fire water flow in the body 10 is made.

On the other hand, a fire hose (not shown in the drawing) is connected to the inlet 11 of the main body 10 so that fire water supplied through the fire hose flows along the main body 10 .

It is coupled to the outlet 12 of the fixed pipe 20 of the present invention to provide a flow path for firefighting water.

Accordingly, the flow of firefighting water is made along the longitudinal direction of the fixed pipe 20 .

At this time, the fixed pipe 20 includes a through hole 21 formed at intervals around one end of the longitudinal direction adjacent to the injection head 50, so that the fire water flows from the inside of the fixed tube 20 to the outside by the through hole 21 . this is done

And the fixed tube 20 includes a stepped 22 formed on the inner surface of one end in the longitudinal direction adjacent to the injection head 50, so that the blade 32 of the deflector 30 described below is caught in the step 22. Accordingly, the deflector 30 is prevented from being separated.

On the other hand, a spiral (reference numeral not shown) is formed on the outer circumferential surface of the fixed tube 20 , thereby making a spiral engagement with the rotating tube 40 .

The deflector 30 of the present invention is inserted and installed in front of the fixing tube 20 to contact the fire water.

Therefore, as the deflector 30 and the head coupling 53 to be described below are spaced apart, the water for firefighting flows along the jet nozzle 51 of the jet head 50 to be described below, and jet injection is made.

At this time, the deflector 30, the shaft 31 leading to the inside of the fixed tube 20; and a blade 32 coupled to the tip of the shaft 31 , thereby preventing the deflector 30 from being separated as the blade 32 is caught on the step 22 of the fixing tube 20 .

Here, the coupling of the shaft 31 is made by fastening a bolt (reference numeral not shown) passing through the deflector 30 , so that the shaft 31 can be separated as the bolt fastening is released.

And the diameter of the shaft 31 is formed smaller than the inner diameter of the fixed tube 20, so that the flow of fire fighting water is made between the outer peripheral surface of the shaft 31 and the inner peripheral surface of the fixed tube (20).

And the blade 32 is radially disposed around one end in the longitudinal direction of the shaft 31 so that the flow of fire water is made through each of them.

The rotary tube 40 of the present invention is spirally engaged with the outer circumferential surface of the fixed tube 20 , but moves forward or backward according to the rotational direction to switch the fire-fighting water flow path in the fixed tube 20 .

Accordingly, the fire water whose flow path is switched by the rotary tube 40 reaches at least one of the jet nozzle 51 of the jet head 50 and the fine spray hole 52 to be described below.

At this time, a spiral (reference numeral not shown) is formed on the inner circumferential surface of the rotating tube 40 , thereby making a spiral engagement with the fixed tube 20 .

The injection head 50 of the present invention is coupled to the tip of the rotary tube 40 and sprays the fire water flowing along the fixed tube 20 through at least one of the jet nozzle 51 and the fine spray hole 52 .

Therefore, as the fire water sprayed through the injection head 50 reaches the source of the fire, the fire is suppressed.

At this time, the injection head 50, but forming a jet injection port 51 in front of the fixed tube 20, a head coupling 53 in which a protrusion piece 53a of a certain width is formed on the inner circumferential surface; by including a protruding piece 53a ), as the deflector 30 is in close contact with the jet nozzle 51, the fire-fighting water is blocked.

Here, the head coupling 53 includes a Teflon sheet 53b that is fitted to the inner circumferential surface of one end in the longitudinal direction in contact with the outer circumferential surface of the fixed tube 20, and thus the head coupling 53 and the fixed tube 20 by the Teflon sheet 53b. ) are in close contact.

On the other hand, the head coupling 53, the protrusion inclined surface (53c) formed at a constant angle around the inner surface of the tip; and an inclined surface 53d extending outward from the protrusion inclined surface 53c and formed at a larger inclination angle than the inclination angle of the protruding inclined surface 53c; It is made, and an obtuse-angle jet jet is made by the fire-fighting water coming into contact with the inclined surface 53d.

On the other hand, the fine atomizing orifices 52 are radially formed on the front surface of the jetting head 50, and are formed as a pair of inner and outer sides at each point to be discharged from the inner fine atomizers 52a and the outer fine atomizers 52b. Fire-fighting water is atomized through mutual collision of fire-fighting water.

At this time, the outer fine spray spheres 52b are connected horizontally, and the inner fine spray spheres 52a are connected in an oblique direction, so that the collision of firefighting water discharged from the outer fine spray spheres 52b and the inner fine spray spheres 52a occurs. is done

In addition, the fine atomizer 52, the first row (52') relatively more adjacent to the center of the injection head (50); and a second row 52" relatively closer to the edge of the jetting head 50; thereby increasing the flow rate of fine atomization, that is, increasing the jetting density.

Here, the inclination angle of the inner fine atomizing spheres 52a of the second row 52″ is 60-80°.

If the inclination angle of the inner fine spray hole 52a of the second row 52" is less than 60 degrees, the firefighting water sprayed through this may go crazy with the firefighting water sprayed through the first row 52', and the spraying interference may follow, When the inclination angle of the inner fine spray hole 52a of the second row 52" exceeds 80°, firefighting water sprayed through this and the outer fine spray hole 52b of the second row 52" are sprayed through Since the collision of the fire water is excessive, the straightness of the fine spraying through the second row 52" may be reduced. It is preferable to be

In addition, the inclination angle of the fine atomizing spheres 52a inside the first row 52' is formed to be smaller than the inclination angle of the fine atomizing spheres 52a inside the second row 52". The fine jetting through 52) and the fine jetting through the second row (52") fine atomizing orifices 52 are performed without interference.

For example, the inclination angle of the fine atomizing spheres 52a inside the first row 52' may be 40°, and the inclination angle of the fine atomizing spheres 52a inside the second row 52' may be 75°.

In addition, the collision-type fine spray fire pipe window (A) according to the present invention may further include a wire filter (60) inserted and installed at one end in the longitudinal direction of the fixed pipe (20).

Accordingly, as foreign substances contained in the fire-fighting water flowing along the fixed pipe 20 are filtered out by the wire filter 60 , the clogging of the fine spray sphere 52 is prevented.

Hereinafter, the fire suppression through the collision-type fine spray fire pipe window (A) according to the present invention will be described in detail.

In the present invention, a fire hose is connected to the inlet 11 of the main body 10 , and water supplied through the fire hose is introduced into the main body 10 through the inlet 11 .

And the fixed pipe 20 is coupled to the outlet 12 of the main body 10 , and firefighting water flowing out through the outlet 12 flows along the fixed pipe 20 .

And the injection head 50 is positioned in front of the fixed tube 20 , and the fire water flowing along the fixed tube 20 is sprayed through the injection head 50 .

Therefore, as the fire-fighting water sprayed through the injection head 50 reaches the source of the fire, the fire is suppressed.

At this time, if fire water is unintentionally sprayed, it may lead to an accident.

However, the main body 10 of the present invention includes a ball valve 13 for controlling the flow of firefighting water between the inlet 11 and the outlet 12; and a lever 14 that opens and closes by rotating the ball valve 13; unintentional fire-fighting water because the fire-fighting water is sprayed only in a state in which the ball valve 13 is opened by the operation of the lever 14. Accidents caused by spraying are prevented.

On the other hand, when fire-fighting water is sprayed in one form, for example, in the form of a stream (corresponding to the jet jet of the present invention), it may be difficult to suppress the fire.

That is, in the case of an oil fire, etc., when firefighting water is sprayed in the form of a stream, the oil is dispersed and spread by the injection pressure, so it may be difficult to extinguish the fire.

However, the present invention includes a rotary tube 40 that moves forward or backward in the fixed tube 20 to switch the fire-fighting water flow path in the fixed tube 20. As shown in FIG. 9, the movement of the rotary tube 40 In other words, according to the rotation, the injection form of the fire-fighting water through the injection head 50 is switched, and more specifically, the fire-fighting water can Since it is sprayed, the type of injection is changed according to the type of fire, for example, in case of an oil fire, fire suppression may be smooth by finely spraying firefighting water, and in the case of a large fire, fire suppression may be smooth by jetting firefighting water at an obtuse angle.

At this time, the fine spraying of fire water is made by the maximum advance of the rotary tube 40 , that is, the rotary tube 40 is located at the farthest distance from the main body 10 .

That is, in the state in which the rotary tube 40 is advanced the maximum, the through hole 21 formed around one end of the longitudinal direction of the fixed tube 20 in contact with the head coupling 53 is opened as shown in FIG. 3 , Since the fire-fighting water in the fixed pipe 20 reaches the micro-spray port 52 of the jet head 50 through the through-hole 21, the fire-fighting water is micro-sprayed by this.

Here, when the fine atomized particles are rotated, the inertia force is lowered, and the penetration force into the flame may be reduced.

However, in the present invention, the fine spray spheres 52 are radially formed on the front surface of the jetting head 50, and are formed as a pair of inner and outer sides at each point, as shown in FIG. Since firefighting water discharged from the fine spray port 52b collides with each other to be atomized, the swirling flow of the fine atomized particles is prevented, so that penetration into the flame can be smooth, and fire suppression can be smooth.

In addition, the fine atomized particles generated by the collision have various sizes as well as straightness. Since the spraying distance is maximized, fire suppression can be smooth.

In addition, the fine atomizer 52, the first row (52') relatively more adjacent to the center of the injection head (50); and a second row 52" relatively closer to the edge of the jetting head 50; As the flow rate of the fine mist increases, that is, the injection becomes higher, fire suppression can be smoother.

And the mixed injection of firefighting water is made as the reversing of the rotary tube 40 from the previous state, more specifically, the fine spray state.

That is, when the rotary tube 40 moves backward a certain distance from the maximum forward state, the jet head 50 coupled to the tip thereof not only moves backward, but also forms a jet nozzle 51 in the jet head 50. 53) Also, as shown in FIG. 4, the opening of the through hole 21 of the fixed tube 20 is partially blocked and spaced apart from the deflector 30 as shown in FIG. The fine spraying of the firefighting water reaching 52) is made, and the jetting of the firefighting water reaching the jet nozzle 51 that is opened by the separation between the head coupling 53 and the deflector 30 is made.

And the jet jet of firefighting water is made as the reversing of the rotary tube 40 further proceeds from the previous state, more specifically, the mixed injection state.

That is, when the rotary tube 40, which has moved backward at the time of fire-fighting water mixing injection, is further moved backward by a certain distance, the jet head 50 coupled to the tip thereof not only moves backward, but also forms a jet nozzle 51 in the jet head 50. The head coupling 53 is also moved backward, and as shown in FIG. 5 , the opening of the through hole 21 of the fixed tube 20 is completely blocked and the head coupling 53 and the deflector 30 are further separated from the deflector 30 . ), the fire water reaching the jet nozzle 51 that is more open as the separation width between spraying takes place

And the acute-angle jet injection of fire water is made as the reversing of the rotary tube 40 from the previous state, more specifically, the jet injection state further proceeds.

That is, when the rotary tube 40, which has moved backward at the time of jet spraying of fire water, is further moved backward by a certain distance, the jet head 50 coupled to the tip thereof not only moves backward, but also forms a jet nozzle 51 in the jet head 50. The head coupling 53 is also moved backward, and as shown in FIG. 6 , the opening of the through hole 21 of the fixing tube 20 is completely blocked and the head coupling 53 and the deflector 30 are further separated from the deflector 30 . ) as the separation width between them increases, the fire water that reaches the jet nozzle 51 that is more open is in contact with the protrusion inclined surface 53c formed around the inner surface of the tip of the head coupling 53 and is in contact with an acute angle, for example, an injection angle of 40°. Jet injection is performed.

And the obtuse jet jet of fire water is made as the reversing of the rotary tube 40 further proceeds from the previous state, more specifically, the acute angle jet injection state.

That is, when the rotary tube 40, which has moved backward at the time of the acute-angle jet of firefighting water, is further moved backward by a certain distance, the jet head 50 coupled to the tip thereof not only moves backward, but also the jet nozzle 51 is provided to the jet head 50. The head coupling 53 to form is also moved backward, so that the opening of the through hole 21 of the fixing tube 20 is completely blocked as shown in FIG. 30) As the separation width between them increases, the fire water that reaches the jet nozzle 51 that is more open comes into contact with the inclined surface 53d formed around the inner surface of the tip of the head coupling 53 and has an obtuse angle, for example, a spray angle of 120°. Jet injection is performed.

In the fire-fighting water spraying process described above, as the head coupling 53 moves backward and the separation width from the deflector 30 increases, the injection flow rate increases. The separation width between the head coupling 53 and the deflector 30 is the most In the case of an obtuse-angle jet jet that becomes larger, the jet of the maximum flow rate is achieved.

However, water damage may occur if a large flow rate greater than jet jet is performed from the initial stage of spraying water for firefighting.

However, in the present invention, the fine spray, fine and jet mixed injection, jet injection, acute-angle jet injection, and obtuse-angle jet injection can be sequentially performed according to the progress of the rotary tube 40, from the initial fine spraying of fire water spray. The occurrence of water damage can be minimized by starting and gradually increasing the flow rate.

And by gradually increasing the flow rate starting from the initial fine spray of fire water spray, the user can respond to the gradually increasing recoil, so that the use is safe, that is, accidents caused by sudden recoil can be prevented.

On the other hand, the present invention can prevent the clogging of the fine spray sphere (52).

That is, the present invention may further include a wire filter 60 that is inserted and installed at one end in the longitudinal direction of the fixed tube 20 . Since foreign substances contained in the fire-fighting water directed to the spray port 52 are filtered, clogging of the fine atomizer 52 due to foreign substances can be prevented, so that the fine atomization through the fine atomization port 52 can be continuously smooth.

At this time, since the foreign substances caught in the wire filter 60 are washed by the pressure action during jet injection and are sprayed together with the fire fighting water, the hassle of removing the foreign substances from the wire filter 60 can be reduced.

Since the present invention as described above is not limited to the above-described embodiments, it can be changed within the scope without departing from the gist of the present invention claimed in the claims, and such changes are the present invention defined by the following claims. fall within the protection scope of the invention.
