Description

{fire fighting nozzle with a function three dimensional circular spraying of fire fighting water}

The present invention relates to a fire-fighting pipe, and more specifically, to a fire-fighting pipe that not only allows stepwise control of the flow rate of fire-fighting water, but also allows three-dimensional circular spraying of fire-fighting water, thereby enabling smooth and safe suppression of various and complex fires. This relates to a fire-fighting window with a three-dimensional circular spray function.

If a fire breaks out in residential or industrial facilities, it can lead to enormous human and material damage.

Accordingly, not only are many people involved paying attention to fire prevention and fire suppression, but various firefighting facilities are being operated for fire prevention and fire suppression.

Meanwhile, indoor fire hydrants and fire trucks are equipped with fire hoses, so fire-fighting water from water hydrants and tanks can be easily transported to the vicinity of a fire outbreak through the fire hose.

In addition, a fire pipe is provided at the tip of the fire hose, so that firefighting water transported through the fire hose can be sprayed to the source of the fire through the fire pipe.

Therefore, fire suppression can be accomplished depending on the fire-fighting water sprayed through the fire pipe and reaching the location of the fire.

At this time, the 'radial fire pipe window' as disclosed in Republic of Korea Patent No. 10-0262197 is mainly used as a fire pipe window.

Radial fire pipes not only allow direct spraying of fire-fighting water, but also allow fire-fighting water to be radiated (approximately 130° angle) by adjusting the spray angle, so the range of fire-fighting water can be expanded, making fire suppression easier.

However, the conventional radial fire pipe does not spray uniformly as the spray angle increases, forming a hollow in the center of the spray angle, which not only reduces the fire suppression effect, but also causes the flame to flow back into the hollow area due to negative pressure, affecting firefighters. As a result, there was a problem that firefighters were put in danger.

For this reason, while using radial fire pipes, fire suppression had to be attempted primarily through direct fire, which led to the problem that the fire suppression effectiveness was deteriorated.

In addition, most of the conventional radial fire pipes not only have a significant spray particle size of approximately 3 to 5 mm for fire fighting water, but also have a unified radiation flow rate, so for example, when entering the room is required to extinguish a fire, the high temperature at the ceiling is maintained for the safety of firefighters. The pulsing function for cooling the gas cools the temperature inside the room to prevent explosive fires such as over-flushing and ensures the safety of the entrance and exit routes. However, the water particles are too large for a conventional fire-fighting window and Because the radiation flow rate could not be controlled depending on the situation, there was a problem that the discharged fire extinguishing water flowed to the floor without cooling, or there was a growing concern about safety accidents due to explosive water vapor caused by excessive discharge flow rate.

For the above reasons, attempts are being made in this field to develop fire-fighting pipes that can control the flow rate of fire-fighting water in stages and make three-dimensional circular sprays that can be sprayed uniformly by reducing the size of water particles. However, satisfactory results have not been obtained to date. This is the situation.

Republic of Korea Patent No. 10-0262197

The present invention was proposed to solve the problems of the prior art as described above, and not only can step-by-step control of the flow rate of fire-fighting water be achieved, but also a three-dimensional circular spray of fire-fighting water in a uniform spray form with small water particles and no hollow phenomenon. The purpose is to provide a fire extinguisher that enables smooth and safe suppression of diverse and complex fires.

In order to achieve the above object, the present invention,

A body having an inlet through which fire-fighting water flows in at one end in the longitudinal direction, and an outlet through which fire-fighting water flowing in through the inlet flows out is formed at the other end in the longitudinal direction; A fixed body in the form of a tube coupled to the outlet to provide a flow path for fire-fighting water; A deflector coupled to the tip of the fixed body and having a plurality of injection holes formed in a head portion formed with a larger diameter than other portions; A flow control body in the form of a pipe that partially surrounds the fixed body and the deflector and moves forward or backward by forward or reverse rotation of a flow control ring disposed at an end; A rotating body in the form of a tube that partially surrounds the flow control body and moves forward or backward by its own forward or reverse rotation; And a ring-shaped spinning member rotatably disposed at the tip of the rotating body and having a plurality of wings radially arranged at regular intervals on the front, wherein the fire-fighting water is sprayed through each injection hole of the deflector. They collide with each other and fill the central part at a spray angle within a certain range, and while spraying through the gap between the deflector and the flow control body, they pass through the inclined surface of the tip of the flow control body and rotate against the wing of the spinning member, and rotate at a spray angle within a certain range. We propose a fire-fighting window with a three-dimensional circular spray function of fire-fighting water, which is characterized in that water particles are sprayed in a uniform spray form without small holes.

The main body includes a ball valve that regulates the flow of firefighting water between the inlet and outlet; and a lever that opens and closes the ball valve by rotating it.

The fixing body includes a locking protrusion formed along the circumference of the distal end.

The locking protrusion includes circular grooves formed at regular intervals on the outer peripheral surface.

The injection port of the deflector includes: a first injection port disposed radially at the center of the deflector; and a second injection port disposed radially along the edge of the deflector.

The first injection port moves forward and is inclined 45° inward.

The second injection port includes an inner injection port that moves forward and is inclined 45° outward; and an outer injection port disposed outside the inner injection port and extending horizontally.

The flow control body includes a first spiral groove formed along the circumference of the end; and a second spiral groove formed along the circumference between the end and the tip.

The tip of the flow control body is formed as an inclined surface at a certain angle.

The flow rate control ring of the flow rate control body includes a first contact member elastically contacting the outer peripheral surface of the fixed body.

The first contact member includes a plunger bolt having a groove extending in the longitudinal direction; a spring inserted into the groove of the plunger bolt; and a ball supported by the spring.

The tip of the rotating body is formed as an inclined surface at a certain angle.

The rotating body includes a second contact member elastically contacting the outer peripheral surface of the flow control body.

The second contact member includes a sleeve having a groove extending in the longitudinal direction; a spring inserted into the groove of the sleeve; and a ball supported by the spring.

The wings of the spinning member are disposed to be inclined at a certain angle in one direction.

The fire-fighting pipe window having a three-dimensional circular spray function for fire-fighting water according to the present invention is sprayed while filling the central part by forming a spray angle while the fire-fighting water sprayed through a deflector with a plurality of spray holes collides with each other, and the gap between the deflector and the flow control body is When sprayed through, the fire extinguishing water sprayed along the inclination angle of the tip of the flow control body hits the wings of the spinning member and rotates to form a spray angle, so even at the maximum spray angle, the complex water particles are small and uniformly sprayed without hollows. As it is sprayed, even if the spray angle is different depending on the type of fire, etc., uniform spray without hollows is achieved, and backflow of flame can be prevented even at the maximum spray angle, allowing smooth fire suppression.

In addition, fire-fighting water sprayed from a deflector formed with a plurality of injection ports can make the size of water droplets smaller by collision and scattering by the rotation of the spinning blades, so it has a complex function and is more effective than ever. Effective three-dimensional circular spraying becomes possible.

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

In the explanation below, 'forward' means progress in the direction of fire-fighting water spraying, 'reverse' means progress in the direction opposite to the direction of fire-fighting water spraying, and 'tip' means the longitudinal direction located in the direction of fire-fighting water spraying. It means one end, and 'end' means one end in the longitudinal direction located in the opposite direction to the direction of firefighting water spraying.

As shown in FIGS. 1, 2, and 3, the fire pipe (A) having a three-dimensional circular spray function for firefighting water according to the present invention includes a main body (100): a fixed body (200): a deflector (300); Flow control body (400); Rotating body (500); and a spinning member 600.

The main body 100 of the present invention has an inlet 110 through which fire-fighting water flows in at one end in the longitudinal direction, and an outlet 120 through which fire-fighting water flowing in through the inlet 110 flows out is formed at the other end in the longitudinal direction.

At this time, the main body 100 includes a ball valve 130 that regulates the flow of firefighting water between the inlet 110 and the outlet 120; and a lever 140 that opens and closes the ball valve 130 by rotating it, thereby allowing the fire-fighting water to flow from the inlet 110 toward the outlet 120 as the ball valve 130 is opened by the operation of the lever 140. This comes true.

Meanwhile, a fire hose (not shown in the drawing) is connected to the inlet 110 of the main body 100, so that fire-fighting water supplied through the fire hose flows into the main body 100.

The fixed body 200 of the present invention is in the form of a pipe and is coupled to the outlet 120 to provide a flow path for fire-fighting water.

At this time, the fixing body 200 includes a locking protrusion 210 formed along the circumference of the distal end, so that the first contact member 411 of the flow rate control ring 410, which will be described below, is caught within the locking protrusion 210. Accordingly, the fixed body 200 and the flow control ring 410 can be connected.

Here, the locking protrusion 210 includes circular grooves 211 formed at regular intervals on the outer peripheral surface, so that the ball 411c of the first contact member 411 described below is caught in any one of the circular grooves 211. Accordingly, not only can the rotation of the flow control ring 410 be stopped, but also the ball 411c of the first contact member 411 sequentially passes through the circular groove 211, thereby rotating the flow control ring 410 in stages. This can be done.

The deflector 300 of the present invention is coupled to the tip of the fixed body 200, and has a plurality of injection holes 320 formed in the head portion 310, which is formed with a larger diameter than other parts.

At this time, the injection port 320 includes a first injection port 320' disposed radially at the center of the deflector 300; and a second injection port (320") radially disposed along the edge of the deflector (300), so that the first injection port (320') and the second injection port (320") are used at the center and edge of the deflector (300). Spraying of fire-fighting water may occur.

Here, the first nozzle 320' moves forward and is inclined 45° inward, so that the fire-fighting water sprayed through one of the first nozzles 320' becomes the fire-fighting water sprayed through the other first nozzle 320'. Upon collision, it may be sprayed in the form of fine particles of approximately 0.3 to 0.5 mm.

And the second injection port (320") includes an inner injection port (321) that moves forward and is inclined at 45° outward; and an outer injection port (322) disposed outside the inner injection port (321) and extending horizontally. By including it, the fire-fighting water sprayed through the inner nozzle 321 can be sprayed in the form of fine particles of approximately 0.3 to 0.5 mm depending on the collision with the fire-fighting water sprayed through the outer nozzle 322.

Meanwhile, the deflector 300 is coupled to the tip of the fixed body 200 by fastening bolts (not shown), thereby preventing unintentional separation from the fixed body 200.

The flow control body 400 of the present invention is in the form of a tube, and partially surrounds the fixed body 200 and the deflector 300, and is subject to forward or reverse rotation of the flow control ring 410 disposed at the end. Move forward or backward by

At this time, the flow control body 400 includes a first spiral groove 420 formed along the circumference of the end; And a second spiral groove 430 formed along the circumference between the distal end and the tip, thereby penetrating the first spiral groove 420 and contacting the fixed body 200. The first contact member of the flow control ring 410 As (411) rotates along the first spiral groove 420, the flow control body 400 can be moved forward or backward, and the second contact member 510 of the rotating body 500, described below, is the first. The rotating body 500 can be moved forward or backward by rotating while being bitten by the two-helix groove 430.

In addition, the flow control body 400 has a tip formed with an inclined surface at a certain angle, so that the firefighting water flowing in from the fixed body 200 spreads outward within the range of 120 to 130° and is sprayed, that is, radiated, as it progresses along the inclined surface. You can.

And the flow rate control ring 410 of the flow rate control body 400 includes a first contact member 411 that elastically contacts the outer peripheral surface of the fixed body 200, so that the first contact member 411 is attached to the fixed body 200. The flow control body 400 can be moved forward or backward by rotating along the formed first spiral groove 420.

At this time, the first contact member 411 includes a plunger bolt 411a having a groove (not shown) extending in the longitudinal direction; A spring (411b) inserted into the groove of the plunger bolt (411a); and a ball 411c supported by the spring 411b, so that the ball 411c supported by the spring 411b flows along the longitudinal direction of the groove of the plunger bolt 411a, thereby forming the first contact member 411. ) can elastically contact the outer peripheral surface of the fixed body (200).

On the other hand, when the flow control body 400 advances due to one-way rotation of the flow control ring 410, the gap between the tip of the flow control body 400 and the head part 310 of the deflector 300 narrows, so the corresponding area is closed. As the flow rate of fire-fighting water decreases, the fire-fighting water injection flow rate decreases, and when the flow rate control body 400 moves backwards due to rotation of the flow control ring 410 in the other direction, the tip of the flow control body 400 and the deflector 300 Since the gap between the head portions 310 is widened, the flow rate of fire-fighting water through the corresponding area increases, thereby increasing the fire-fighting water spray flow rate, and thus the fire-fighting water spray flow rate can be adjusted.

At this time, the flow control body 400 has a flushing function.

That is, as firefighting water is sprayed with the flow control body 400 in the maximum backward state, foreign substances previously caught in the spray port 320 of the deflector 300 can be removed.

In addition, the flow control body 400 includes a fixing pin (not shown) that is fastened to the slit groove (not shown) of the fixed body 200, so that when the flow control ring 410 rotates, the fixing pin prevents rotation and moves forward. Alternatively, only backward movement can be performed.

The rotating body 500 of the present invention is in the form of a tube, and partially surrounds the flow control body 400, and moves forward or backward by its own forward or reverse rotation.

At this time, the tip of the rotating body 500 is formed as an inclined surface at a certain angle, so as the firefighting water flowing in from the flow control body 400 progresses along the inclined surface, it spreads outward within the range of 120 to 130° and sprays, that is, radiates. It can be.

And the rotating body 500 includes a second contact member 510 that elastically contacts the outer peripheral surface of the flow rate control body 400, so that the second contact member 510 is a second spiral groove formed in the flow rate control body 400. By rotating along 430, the rotating body 500 can be moved forward or backward.

Here, the second contact member 510 includes a sleeve 511 in which a groove (not shown) extending in the longitudinal direction is formed; A spring 512 inserted into the groove of the sleeve 511; and a ball 513 supported by the spring 512, so that the second contact member 510 moves as the ball 513 supported by the spring 512 flows along the longitudinal direction of the groove of the sleeve 511. It can elastically contact the second spiral groove 430 on the outer peripheral surface of the flow control body 400.

On the other hand, when the rotary body 500 moves forward due to its one-way rotation, the fire-fighting water flowing in from the flow control body 400 comes into contact with the inner surface of the rotary body 500 and moves horizontally, so that the fire-fighting water flows directly. When the rotary body 500 moves backward by rotating in the other direction, some of the firefighting water flowing in from the flow control body 400 travels along the slope of the tip of the rotary body 500, so it spreads outward and sprays, in other words. Since radiation occurs, the spray angle of firefighting water can be adjusted.

At this time, when the reverse amplitude of the rotating body 500 increases, the contact between the fire-fighting water flowing in from the flow control body 400 and the inner surface of the rotating body 500 decreases, and the fire-fighting water can be sprayed further outward. The square can become larger.

In addition, a bumper 520 made of rubber is coupled to the outer peripheral surface of the rotating body 500, so that the bumper 520 not only prevents slipping when the rotating body 500 rotates, but also prevents the rotating body 500 from impacting from the outside. Damage can be prevented.

At this time, the bumper 520 can be prevented from being unintentionally separated from the rotary body 500 as the cover 530 is coupled to the outer peripheral surface of the distal end of the rotary body 500.

Here, the cover 530 may be coupled to the outer peripheral surface of the distal end of the rotating body 500 by fastening a fixing bolt (not shown).

The spinning member 600 of the present invention has a ring shape and is rotatably disposed at the tip of the rotating body 500, with a plurality of wings 610 arranged radially at regular intervals on the front surface.

At this time, the wings 610 are arranged to be inclined at a certain angle in one direction, so that the firefighting water traveling through the inclined surface of the rotating body 500 comes into contact with the wings 610 of the spinning member 600 and rotates together with the spinning member 600. and can be sprayed.

Here, the Teflon ring 620 is installed before and after the spinning member 600, so that the spring member 600 can rotate smoothly in the rotating body 500 due to the Teflon ring 620.

The spraying of firefighting water through the firefighting pipe (A) having a three-dimensional circular spraying function of firefighting water according to the present invention will be described in detail as follows.

In the present invention, a fixed body 200 in the form of a tube is coupled to the outlet 120 of the main body 100, and the firefighting water flowing in through the inlet 110 of the main body 100 passes through the outlet 120 to the fixed body ( 200) flows inside.

And in the present invention, a deflector 300 having a plurality of nozzles 320 formed in the head portion 310 is coupled to the tip of the fixed body 200, so that the firefighting water flowing into the fixed body 200 flows into each of the deflectors 300. Since it can be sprayed through the injection hole 320, fire suppression can be achieved.

At this time, the injection port 320 of the deflector 300 includes a first injection port 320' disposed radially at the center of the deflector 300; and a second injection port (320") disposed radially along the edge of the deflector (300), wherein the first injection port (320') and the second injection port (320") are used to form a space between the center and the center of the deflector (300). Since fire-fighting water can be sprayed from the edge, fire suppression can be achieved by directing it toward the source of the fire.

Here, the first nozzle 320' moves forward and is inclined 45° inward, so that the firefighting water sprayed through one of the first nozzles 320' is sprayed through the other first nozzle 320'. When it collides with fire-fighting water, the fire-fighting water can be sprayed in the form of fine particles, and the second nozzle (320") is an inner nozzle (321) that moves forward and is inclined at 45° outward; and the outer side of the inner nozzle (321) It is disposed in the outer nozzle 322, which is arranged to run horizontally. It includes a fire-fighting water sprayed through the inner nozzle 321 and collides with the fire-fighting water sprayed through the outer nozzle 322, so that the fire-fighting water sprays into fine particles. Since it can be sprayed in a certain shape, especially when entry into the room is required to extinguish a fire, high-temperature gas cooling inside the room can be smoothly achieved by spraying firefighting water through the first nozzle (320') and the second nozzle (320"). You can.

However, if fire-fighting water is sprayed only at a constant flow rate and in a certain spray form, for example, in a direct spray form, the fire suppression effect may be reduced.

However, the present invention is a flow control body in the form of a tube that partially surrounds the fixed body 200 and the deflector 300 and moves forward or backward by rotating the flow control ring 410 disposed at the end in the forward or reverse direction. (400); As shown in FIG. 5, as the flow control body 400 advances by rotating the flow control ring 410 in one direction, the tip of the flow control body 400 and the deflector 300 The gap between the head portions 310 narrows and the amount of fire-fighting water flow through the relevant area decreases, resulting in a decrease in the fire-fighting water injection flow rate, and as shown in FIG. 4, by rotating the flow control ring 410 in the other direction. As the flow control body 400 moves backward, the gap between the tip of the flow control body 400 and the head part 310 of the deflector 300 widens, and the amount of firefighting water flow through that area increases, thereby increasing the firefighting water spray flow rate. As a result, the firefighting water spray flow rate can be adjusted within the range of 100 to 500 LPM, so fire suppression can be smoothly performed by increasing the spray flow rate depending on the intensity of the fire.

And the present invention includes a tubular rotating body 500 that partially surrounds the flow control body 400 and moves forward or backward by its own forward or reverse rotation, as shown in Figure 6. Likewise, as the rotary body 500 moves forward due to its one-way rotation, the fire-fighting water flowing in from the flow control body 400 comes into contact with the inner surface of the rotary body 500 and proceeds horizontally, so that the fire-fighting water flows directly. As shown in FIG. 7, as the rotating body 500 moves backward due to its own rotation in the other direction, some of the firefighting water flowing in from the flow control body 400 travels along the slope of the tip of the rotating body 500. It spreads outward and can be sprayed, or in other words, radiated, so fire suppression can be performed smoothly by varying the spray type depending on the type of fire.

At this time, the emission of fire-fighting water proceeds in a complex manner with the direct emission of fire-fighting water, and the fire-fighting water can be sprayed in a three-dimensional circular shape, preventing the creation of hollows during the spraying process of fire-fighting water, thereby preventing the reverse flow of flame through the hollow portion. This allows fire suppression to be carried out more safely.

Here, the fire-fighting water sprayed in a three-dimensional circular shape has less contact with the inner surface of the rotating body 500 as the backward amplitude of the rotating body 500 increases, as shown in FIG. 8, and the inclined surface of the tip of the rotating body 500 As it progresses further outward and sprays, the spray angle can become larger within the range of 120 to 130°, allowing it to reach a wider range of areas where the fire originates.

In addition, the present invention includes a ring-shaped spinning member 600 rotatably disposed at the tip of the rotating body 500, wherein the fire fighting water sprayed through the tip of the rotating body 500 is connected to the spinning member 600 and the spinning member 600. Since it contacts and rotates due to the rotation of the spinning member 600, the water particles become smaller due to the centrifugal force caused by the rotation, and the firefighting water can reach the fire outbreak site more widely.

At this time, the spinning member 600 includes a plurality of wings 610 arranged radially at regular intervals on the front surface and inclined at a certain angle in one direction, and travels along the inclined surface of the rotating body 500. As the fire-fighting water comes into contact with the wings 610 of the spinning member 600, the fire-fighting water may rotate and be sprayed along with the rotation of the spinning member 600.

In addition, a portion of the firefighting water sprayed from the spray port 320 of the deflector 300 may be scattered while rotating by the spinning member 600, so that three-dimensional circular spray can be achieved.

Meanwhile, in the present invention, the flow control body 400 includes a first spiral groove 420 formed along the circumference of the end; and a second spiral groove 430 formed along the circumference between the distal end and the tip, wherein the first spiral groove 410 of the flow control ring 410 penetrates the first spiral groove 420 and contacts the fixed body 200. The flow control body 400 can be moved forward or backward by rotating the contact member 411 along the first spiral groove 420, and the second contact member 510 of the rotating body 500, which will be described below. The rotating body 500 can be moved forward or backward by rotating while being bitten by the second spiral groove 430.

Here, the first contact member 411 includes a plunger bolt 411a having a groove extending in the longitudinal direction; A spring (411b) inserted into the groove of the plunger bolt (411a); and a ball 411c supported by a spring 411b. The second contact member 510 includes a sleeve 511 having a groove extending in the longitudinal direction; A spring 512 inserted into the groove of the sleeve 511; and a ball 513 supported by the spring 512, wherein the ball 411c, 513 supported by the spring 411b, 512 extends in the longitudinal direction of the groove of the plunger bolt or sleeve 411a, 511. As it flows, the first contact member 411 can elastically contact the outer peripheral surface of the fixing body 200 and the second contact member 510 can elastically contact the outer peripheral surface of the flow control body 400.

The present invention as described above is not limited to the above-described embodiments, so changes can be made without departing from the gist of the present invention claimed in the claims, and such changes may be made to the present invention as defined by the claims below. falls within the scope of protection of the invention.

A fire-fighting window with a three-dimensional circular spray function for fire-fighting water, characterized in that it rotates by hitting the blades of the spinning member and is sprayed at a spray angle within a certain range, so that the water particles are sprayed in a uniform spray form without small holes. According to paragraph 1,
The fixing body includes a locking protrusion formed along the circumference of the distal end, and the locking protrusion includes circular grooves formed at regular intervals on the outer peripheral surface. According to paragraph 1,
The injection port of the deflector includes: a first injection port disposed radially at the center of the deflector; and a second nozzle disposed radially along the edge of the deflector, wherein the first nozzle moves forward and is inclined 45° inward, and the second nozzle moves forward and is inclined 45° outward. an inner nozzle formed; And an outer nozzle disposed on the outside of the inner orifice and arranged horizontally. According to paragraph 1,
The fire-fighting water sprayed at a certain angle through the injection port of the deflector has a spray angle adjusted according to the forward or backward motion of the rotating body, and a portion of the fire-fighting water is scattered while rotating as it contacts the spinning member, and the rotating body is rotated at a maximum A fire-fighting window with a three-dimensional circular spray function, characterized in that fire-fighting water is sprayed in a straight line without spreading outward as it comes into contact with the inner wall of the rotating body when moving forward. According to paragraph 1,
As the flow rate control body moves backward due to rotation of the flow rate control ring in one direction and the gap between the tip of the flow control body and the head of the deflector widens, foreign substances previously caught in the nozzle of the deflector are transferred to the flow control body. A firefighting window having a three-dimensional circular spray function for firefighting water, characterized in that the firefighting water is discharged to the outside and removed between the tip and the head portion of the deflector.
