Description

Water supply device combined with forest firefighting

[0001] The present invention relates to a water supply device for forest firefighting, and more specifically, to enable rapid extinguishing of a forest fire in a mountainous or densely forested area regardless of the season, thereby preventing enormous economic losses due to a large-scale forest fire, and to prevent forest fires by regularly supplying moisture to trees and fallen leaves through a sprinkler during dry seasonal conditions.

[0002] Typically, when a forest fire breaks out, a helicopter takes off and collects water from a nearby hose or river to put out the fire.

[0003] However, in winter, the water in the hose freezes and forms ice, making it difficult to secure the water needed for fire fighting.

[0004] Also, when a forest fire breaks out and a large fire is extinguished, and personnel are deployed to deal with remaining fires, they are given water buckets that they can carry on their backs, and the water that comes out is pumped out manually to put out the remaining fires.

[0005] The method of extinguishing a forest fire using a helicopter involves attaching a bucket to the helicopter with a rope or something similar, filling the bucket with firefighting water from a river or hose, flying it to the forest fire area, and then opening the opening plate installed on the bottom of the bucket to allow the firefighting water contained in the bucket to drain out.

[0006] In addition, the helicopter itself is equipped with a water tank and a water pump, so that fire fighting water is pumped into the water tank from a river or hose, and after flying to the forest fire area, the swing-opening plate installed at the bottom of the water tank is opened to allow the fire fighting water stored in the bucket to be discharged.

[0007] However, firefighting using helicopters has only been done during the day from sunrise to sunset, and forest fires cannot be extinguished at night.

[0008] The law prohibits using helicopters to fight forest fires after sunset. This is a regulation for the safety of helicopters and the lives of passengers, as it is dangerous after sunset due to darkness and lack of visibility of mountain ridges and large trees.

[0009] Meanwhile, the conventional method of forest fire suppression using helicopters involves the helicopter hovering to fill a water tank with water. However, this method has problems such as the flight time of the helicopter, which is too long for urgent fire suppression, making it inefficient for fire suppression and incurring enormous costs.

[0010] And, for nighttime situations where helicopter flights are impossible or for extinguishing fires, residents, government officials, and soldiers are being mobilized to provide manpower.

[0011] Firefighting operations using manpower involve carrying water tanks and personal firefighting equipment on their backs and climbing rugged mountains to extinguish forest fires. However, this method has limitations in accessibility depending on the location of the forest fire or the area requiring extinguishment. In addition, the area for extinguishment is limited, and the water for extinguishing is quickly depleted, requiring frequent travel to a long distance to resupply water. This delays the work and results in very low firefighting efficiency.

[0012] The prior art is as follows.

[0013] Republic of Korea Patent Publication No. 2014-0046773 (Published: April 21, 2014)

[0014] Republic of Korea Patent No. 10-1631229 (Registration date: June 10, 2016)

[0015] The purpose of the present invention is to provide a water supply device for forest fire fighting, which branches out several water supply pipes from a water tank in a mountainous area and pipes them so that when a fire breaks out in a mountainous or forested area, firefighting equipment such as a hose can be connected immediately to enable rapid extinguishing operations.

[0016] Another object of the present invention is to provide a water supply device that is excellent in forest fire prevention by supplying water to dense trees or fallen leaves in dry climate conditions, thereby eliminating the cause of fire.

[0017] Another object of the present invention is to provide a water supply device that also functions as a forest firefighting device, which can prevent the death of various plants, including trees, by supplying an appropriate amount of moisture in dry climate conditions.

[0018] Another object of the present invention is to provide a water supply device for forest firefighting, which automatically discharges water inside a water supply pipe to the outside by automatic or air pressure when the water supply is cut off, thereby eliminating the risk of freezing and enabling rapid firefighting in all four seasons, including the cold winter.

[0019] To achieve this purpose, the composition of the present invention comprises a water tank filled with water through an inlet from a tap water supply or a water truck,

[0020] A discharge pipe that discharges water from the above tank at a predetermined pressure,

[0021] Main branch pipes that are connected to this transmission pipe and branch off the water supply lines into multiple parts,

[0022] Terminal boxes are installed in multiple numbers with spacing maintained in the middle of the above main branch pipes, and the main branch pipes and water supply pipes are connected to each other through couplers installed at the inlet and outlet and at each branch location.

[0023] A hydraulic sprinkler installed in the above water supply pipes and / or main branch pipes so that water rotates and sprays out by the water pressure sent by the pump (P),

[0024] An electric sprinkler installed in the above water supply pipes and / or main branch pipes so that water is rotated and sprayed by the rotation of the motor,

[0025] Drain valves installed in the above main branches and / or water supply pipes to discharge water in the pipes when water pressure is not applied,

[0026] A plurality of control valves mounted on the main branch pipes and / or water supply pipes to supply water or block the water line at a desired time,

[0027] It includes an air supply valve installed at each end of the above main branch pipes and forcibly discharges water remaining inside the pipes by air pressure.

[0028] The above main branch pipe is formed by having a water supply hole in the center for supplying water, and electrical lines and air hoses are respectively routed to the outside of the water supply hole, and the outside is wrapped with a protective material.

[0029] The above terminal box is characterized by installing anti-settlement panels on the ground, forming a number of holes in the floor, supporting the anti-settlement panels by driving anchors into them, and adjusting the installation height of the anchors by bolts and adjusting rings.

[0030] The above hydraulic sprinkler comprises a wing member that rotates by water pressure supplied from a pilot pipe in a direction perpendicular to the cooler body, a screw member that is fixed inside the wing member and rotates together with the wing member, and a nozzle cap that is attached to the end of the wing member and has nozzle holes that are each inclined at a predetermined angle, so that the water stream is sprayed while rotating in an inclined state.

[0031] The above electric sprinkler comprises a rotating member in which a worm and a worm wheel are rotated by a motor in a direction perpendicular to the cooler body and are gear-coupled to rotate, and a nozzle cap attached to the end of the rotating member and having nozzle holes formed at a predetermined angle, so that the water stream is sprayed while rotating in an inclined state.

[0032] According to the present invention, in a mountainous or forested area where there is a risk of fire, several main branches and a number of terminal boxes are installed in the middle of a water tank so that, in the event of a fire, firefighting equipment such as a hose can be connected immediately to enable rapid fire extinguishing operations.

[0033] Additionally, in normal times, it is effective in preventing fires by removing the cause of fire in advance by regularly operating sprinklers to supply sufficient moisture to trees and fallen leaves.

[0034] In addition, when the water supply is cut off, the water inside the water pipe is automatically discharged to the outside, and by forcibly supplying air pressure through the air supply valve, all the water inside the pipe that can be installed in an inclined position is forcibly discharged, so there is no need to worry about freezing, and fire extinguishing work can be done quickly in all four seasons, including the cold winter.

[0035] Therefore, it is possible to prevent fires in mountainous areas with dense forests, and when a fire breaks out, it is possible to quickly extinguish it and extinguish any remaining fires. It also allows firefighting work to be carried out without workers having to carry water or rely on helicopters, which can reduce enormous economic losses.

[0036] Additionally, in drought environments, it provides adequate moisture to prevent the death of expensive trees and plants.

[0048] However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. In addition, the terminology used in this specification is for the purpose of describing the embodiments and is not intended to limit the present invention.

[0049] In this specification, the singular includes the plural unless specifically stated otherwise. As used herein, the terms "comprises" and / or "comprising" do not exclude the presence or addition of other components other than the mentioned components.

[0050] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in a meaning that can be commonly understood by a person of ordinary skill in the art to which the present invention belongs.

[0051] Hereinafter, in order to explain the present invention more specifically, embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0052] Figure 1 is a diagram showing the overall structure of a water supply device for forest firefighting according to the present invention.

[0053] As shown in the drawing, the water supply device for forest fire fighting of the present invention is a device that can be used by connecting to a sprinkler or personal fire fighting equipment in a state where a main branch pipe is installed by branching off into multiple branches along a mountainous area from a water tank (10) filled with a certain amount of water, so that when a fire breaks out, it can be quickly extinguished and any remaining fire can be extinguished, and in dry conditions, it can spray water in advance to block the cause of the fire in advance or promote forest reforestation.

[0054] The above water tank (10) is mainly located at the entrance of a mountainous area and is filled with water supplied from a water supply or water truck through an inlet (11). In some cases, the above water tank (10) may be supplied with water from a fire hydrant, a fire-fighting water tank, or a natural water source such as a reservoir or lake installed in a mountainous area.

[0055] In the above tank (10), a plurality of pumps (P) installed in series are individually operated according to the required pressure, or a plurality of pumps are operated simultaneously, and the water filled inside the tank (10) is discharged through the discharge pipe (20) by the pumps (P).

[0056] It is preferable that an operating room (12) and a machine room (13) for managing the water in the tank (10) be installed on the upper ground of the tank (10).

[0057] The above driver's cabin (12) is provided with a distribution panel for electrical control, a control circuit for a water pressure control pump, a water tank quantity meter, etc.

[0058] The above machine room (13) is provided with water supply pumps (P), an air compressor, and an in-pipe water return valve.

[0059] As shown in Fig. 1, three to five main branch pipes (30) are connected to the above-mentioned discharge pipe (20), and control valves (90) that are operated manually or by remote control of the driver's cabin (12) are installed in the above-mentioned main branch pipe (30), and water can be supplied to the above-mentioned main branch pipe (30) along the selected water supply line according to the opening and closing operation of the above-mentioned control valves (90).

[0060] The present invention includes a main branch pipe (30) that is appropriately arranged according to a mountainous area or mountainous terrain. The cross-sectional structure of the main branch pipe (30) is well illustrated in FIG. 9.

[0061] In the center of the above main branch pipe (30), a water supply hole (31) is installed to supply water, and an electric line (32) and an air hose (33) are respectively routed outside the water supply hole (31), and the outside thereof is formed in a shape in which the outer surface thereof is wrapped with a protective material. Through this, water, electricity, and air are safely supplied to their respective final destinations.

[0062] The above electric line (32) is wired for the purpose of controlling the electric sprinkler (70) and the control valve (90) from a distance.

[0063] The above air hose (33) transmits air pressure from the compressor in the machine room to the inside of the main branch pipe (30) through the air supply valve (100), thereby forcibly transporting water inside the pipe located at a high altitude in a mountainous area toward the water tank (10). (See Fig. 1)

[0064] The present invention includes a terminal box (40) that continuously connects the main branch pipe (30).

[0065] In the present invention, since the total pipe length from the water tank (10) is very long, for example, about 300 to 400 m, it is preferable to install terminal boxes (40) at regular intervals (about 30 to 40 m). In addition to the function of extending and connecting the main branch pipes (30) to each other, the terminal box (40) performs the function of branching and installing the water supply pipe (41) from the main branch pipe (30). The main branch pipes (30) are continuously connected through the terminal box (40).

[0066] The structure of the above terminal box (40) is illustrated in Fig. 8.

[0067] The above terminal box (40) presents an embodiment in which a water supply pipe (41) is branched to connect to the water supply line of the main branch pipe (30). A coupler (50) can be installed in this water supply pipe (41) to allow a portable fire hose or sprinkler to be installed.

[0068] The above terminal box (40) is shown in a state where the main branch pipe (30) passes through a state where it is wrapped with an insulating material (48) inside a box that can be opened and closed through a cover (47), and a coupler (50) is installed at each of the inlet and / or outlet of the main branch pipe (30). In this state, the water supply line or electric line (32) and the air hose (33) can be connected without being disconnected.

[0069] It is preferable that the terminal box (40) above be installed by being fixed to the ground. When the terminal box (40) is fixed to the ground, it is preferable to install anti-settlement panels (42) on the ground, form a number of holes (43) in the floor, and allow grass or various plants to grow through the holes (43) to protect the ecology and prevent the soil from being washed away by rainwater, etc. It is preferable to support the anti-settlement panels (42) by driving anchors (45), and to adjust the height of the anchors (45) by means of bolts (42) installed on the bottom and adjusting rings (46) installed on the upper surface.

[0070] The above terminal box (40) is installed by branching off another water supply pipe (41) in a direction perpendicular to the main branch pipe (30), and a coupler (50) can be installed in the water supply pipe (41).

[0071] The present invention includes a coupler (50) that can more efficiently utilize water supplied from the main branch pipe (30) or the water supply pipe (41) for fire suppression purposes. The coupler (50) is well illustrated in Fig. 7.

[0072] The above coupler (50) is preferably a coupling whose connection is locked or unlocked by a lever (51), and an equivalent used for this function and purpose may be used. Examples of such equivalents include a quick coupler or various pipe connection components already available on the market in various structures.

[0073] The above coupler (50) can be used to connect a portable fire hose or sprinkler owned by an individual, or a fire suppression device brought in from outside. Here, it should be noted that a means capable of connecting a hose or cable, i.e., a connecting nipple or joint, may be selected in place of the above coupler (50).

[0074] Accordingly, at each terminal box (40) location, a personal fire extinguishing device or a hydraulic sprinkler (60) or an electric sprinkler (70) can be selectively installed through a coupler (50) to prevent fire by supplying sufficient moisture in normal times, and in the event of a fire, a personal fire hose can be connected at the required location to enable rapid extinguishment and extinguishment of remaining fire.

[0075] The present invention includes a hydraulic sprinkler (60). Figures 2 and 3 illustrate the structure of the hydraulic sprinkler (60).

[0076] The above hydraulic sprinkler (60) is composed of a wing member (63) that rotates by water pressure supplied to the pilot pipe (62) in a direction perpendicular to the cooler body (61), a screw member (64) that is fixed inside the wing member (63) and rotates together with the wing member, and a nozzle cap (65) that is attached to the end of the wing member (63) and has nozzle holes (66) that are each slanted at a predetermined angle.

[0077] Accordingly, when a portion of the water supplied at a predetermined pressure into the main branch pipe (30) is branched off and supplied to the pilot pipe (62), the screw member (64) and nozzle cap (65) are forcibly rotated simultaneously together with the wing member (63) by the water pressure.

[0078] The screw member (64) has a screw formed on the outside to guide water to rotate along the screw surface, and several nozzle holes (66) are drilled slantedly in the nozzle cap (65), so that water rotates slantedly along the incline of the nozzle holes (66) and is sprayed. Accordingly, water can be supplied evenly to a wide area through the hydraulic sprinkler (60).

[0079] The present invention includes an electric sprinkler (70). Figures 4 and 5 illustrate the structure of the electric sprinkler (70).

[0080] The above electric sprinkler (70) is composed of a rotating member (75) in which a worm (73) and a worm wheel (74) are rotated by a motor (72) in a direction perpendicular to a cooler body (71), as shown in FIGS. 4 and 5, and a nozzle cap (65) attached to the end of the rotating member (75) and having nozzle holes (66) formed at a predetermined angle.

[0081] The above electric sprinkler (70) is driven by an electric power source through an electric line to drive a motor (72) so that water is sprayed while rotating in an inclined state along the inclined angle of a nozzle hole (66) drilled in a nozzle cap (65).

[0082] Therefore, water can be supplied evenly to a wide area through the electric sprinkler (70).

[0083] The above hydraulic sprinkler (60) has the advantage of being able to operate even in an environment where the power supply is cut off, while the above electric sprinkler (70) has the advantage of being able to freely control operation and stop at a desired time by remotely controlling the motor (72).

[0084] The present invention installs both a hydraulic sprinkler (60) and an electric sprinkler (70) having such functions, thereby enabling extinguishment and extinguishment of a forest fire in any environment.

[0085] The present invention can operate a system for draining water inside a pipe after efficiently extinguishing a forest fire by installing the hydraulic sprinkler (60) and the electric sprinkler (70). This system can be implemented by a drain valve (80) and / or an air supply valve (100).

[0086] The present invention includes a drain valve (80) that allows water inside the pipe to be naturally discharged when the water supply by water pressure is interrupted.

[0087] The above drain valve (80) is installed at the lower side of each sprinkler (60) (70), as shown in FIGS. 2 and 4. When no water pressure is applied, the drain valve (80) maintains the passage in a forcibly opened state by the elasticity of the spring (82), so that the water that has been forcibly transported and filled inside the pipe is discharged to the outside through the drain valve (80) or is used to be recovered into the inside of the water tank (10). The water discharged to the outside through the drain valve (80) has the effect of supplying water to the surrounding fallen leaves or forests.

[0088] The above drain valve (80) has the same structure in that, as shown in FIGS. 2 and 4, the ball (81) is elastically supported by a spring (82), so that when water pressure is applied, the outlet is sealed by the water pressure, whereas when the water pressure inside the pipe is removed, the outlet is opened by the spring (82), so that the water inside the pipe is discharged to the outside.

[0089] In addition, the present invention includes an air supply valve (100) that forcibly discharges water inside the pipe when water supply by water pressure is interrupted.

[0090] The above air supply valve (100) is well illustrated in Fig. 10. The air supply valve (100) performs a function of recovering water remaining inside the pipe or preventing freezing of the pipe in winter. In case it is necessary to prevent freezing of the pipe in winter for use in water recovery, an air hose (h) is connected to the air supply valve (100) located at the top of the main branch pipe (30), and air pressure is supplied from an air compressor provided in the machine room (13) through the air hose (h).

[0091] In that case, the air pressure presses the ball (102) to suppress the elasticity of the spring (101), and the balls (102) are pushed out to open the passage inside the pipe, so that air is supplied inside the pipe, and the water remaining inside the pipe is forcibly pushed out, so that it is discharged to the outside through the drain valve (80) or pushed down toward the water tank (10) to remove the water inside the pipe. Therefore, freezing in winter due to water inside the pipe is prevented.

[0092] The above drain valve (80) is mainly installed at the lower end of the hydraulic sprinkler (60) or electric sprinkler (70) and the water supply pipe (41) or main branch pipe (30), and when water pressure is not applied, the passage is opened to discharge water inside the pipe to the outside at any time.

[0093] The water recovered by the above drain valve (80) or the above air supply valve (100) flows down to the recovery pipe (14) existing between the lower part of the main branch pipe (30) and the water tank (10), and the water left inside the pipe is recovered to the water tank (10) through the recovery pipe (14), so freezing in winter can be prevented, and the recovered water can be recycled again in the water tank (10).

[0094] Additionally, the present invention can also provide an appropriate supply of water to forests in drought environments.

[0095] In addition, the present invention branches a water supply pipe (41) to the terminal box (40) and connects a sprinkler or personal fire extinguishing equipment to the water supply pipe (41), so that water can be quickly supplied to the equipment of a fire extinguishing worker when necessary, and can also prevent fire by spraying water toward fallen leaves on the ground.

[0096] The present invention allows the main branch pipe (30) to be installed in a single continuous line, or in multiple branched lines depending on the mountainous terrain, thereby enabling it to cover a wide area. This can be sufficiently achieved by utilizing the terminal box (40).

[0097] In addition, the present invention can connect a coupler (50) to a water supply pipe (41) branched from the terminal box (40), and can connect personal fire extinguishing equipment or various fire extinguishing equipment supplied from outside to the coupler (50), thereby enabling more effective forest fire suppression even in rugged mountainous regions. This will serve as an advantage that can further effectively enhance the fire suppression function of the present invention.

[0098] In addition, in the event of a fire, etc., the sprinkler pipe mounted on the coupler (50) is disassembled, and personal fire extinguishing equipment is connected so that water can be quickly sprayed to the fire extinguishing worker's equipment, and fire extinguishing work and extinguishing work can be carried out toward fallen leaves on the ground.

[0099] Meanwhile, the present invention has the advantage of enabling immediate response to fire reports by installing multiple control valves (90) in the main branch pipe (30) and water supply pipe (41). This means that the firefighting device of the present invention can be effectively utilized even in situations where immediate dispatch from outside is not possible, or late at night when all activities are significantly restricted. This is because the control valves (90) can be immediately activated from outside, operated remotely, and the water supply line can be quickly opened and closed by the operator.

[0100] For remote operation of the above control valves (90), an electronic valve may be selected and installed.

[0101] Accordingly, the present invention operates the pumps (P) by opening the control valve (90) when a fire is detected or to supply water to fallen leaves or dense forests accumulated in mountainous areas due to dry climate, so that water filled in the water tank (10) is selectively or simultaneously supplied to the main branch pipe (30) and the water supply pipe (41) at a predetermined pressure, thereby allowing water to be supplied from the hydraulic sprinkler (60) and / or the electric sprinkler (70).

[0102] Furthermore, the present invention can efficiently suppress a fire by combining various fire suppression equipment present at the scene of a fire when a fire occurs. This is because personal fire extinguishing equipment can be connected to the coupler (50) of the water supply pipe (41) branched from the terminal box (40) or additional fire extinguishing equipment can be connected to suppress a forest fire.

[0103] In addition, the present invention can selectively supply water only to the necessary water supply lines by operating the control valves (90), and can also control water supply to each of the water supply lines.

[0104] Furthermore, the present invention can efficiently perform post-fire management after fire suppression. To this end, the present invention allows water to be sprayed from sprinklers or personal fire extinguishing equipment, and then, after fire suppression is complete, the selected control valve (90) is closed to cut off the water supply, automatically discharging any remaining water inside the pipe to the outside through the drain valves (80).

[0105] In addition, by connecting the air hose (h) to the air supply valve (100) and applying strong air pressure to the inside of the pipe, all the water inside the main branch pipe (30) that was piped at an inclined position can be forcibly discharged to the outside, thereby preventing the pipe from freezing in the winter.

[0106] In addition, when the fire is extinguished and the pump (P) operation is stopped by closing the control valve (90), the water pressure applied inside the pipe is lowered, and the elasticity of the spring (82) of the drain valve (80) pushes the ball (81) out of the ball seat, thereby opening the passage and allowing drainage.

[0107] In addition, the present invention can recover the water to the tank (10) by inducing the water to flow down to the recovery pipe (14), or can install a pipe so that it falls to the soil on the ground.

[0108] In this way, when the control valve (90) is blocked and the operation of the pump (P) is stopped, the water inside the pipe is automatically discharged, thereby preventing the main branch pipe (30) and water supply pipe (41) from freezing, especially in the cold winter season.

[0109] In addition, in case of a fire in a mountainous area, not only can a personal fire extinguishing device be connected directly to the location of the coupler (50) that has been installed in advance to enable rapid fire extinguishing, but also, in normal times, there is a fire prevention effect that eliminates the cause of the fire in advance by supplying moisture to trees or fallen leaves in the mountainous area.

[0110] In addition, in drought environments, it provides water to forests, preventing the death of various plants, and provides economic benefits by allowing expensive trees to be grown in optimal environments.

[0111] The present invention described above is not limited to the above-described embodiments and drawings, and it will be apparent to a person skilled in the art to which the present invention pertains that various substitutions, modifications, and changes are possible within a scope that does not depart from the technical spirit of the present invention.

[0112]

[0113] The present invention can quickly extinguish a forest fire when it occurs and contribute to forest reforestation by supplying water when it is dry.
