Description

{mobile water dispensable apparatus}

The present invention relates to a mobile sprinkler device that can be moved by a user to a location where sprinkler work is required to provide water for firefighting, agricultural use, etc.

In general, forest fires occur frequently in the spring when the climate is dry, and when forest fires occur simultaneously in multiple places, a national disaster occurs, and even if all the firefighting equipment of local fire departments and related firefighting companies are mobilized, it is difficult to quickly extinguish the fire. For example, in the case of the recent large-scale forest fire in Gangwon Province, even if all the fire trucks in the fire area and surrounding areas were mobilized, it was not easy to extinguish the fire.

Since large fire trucks are equipped with large water tanks, their overall width, height, and depth are large, and in cases where there is no wide passageway for entry, they cannot approach the scene of the fire closely, and thus there is a problem in that they cannot quickly put out the fire at an early stage. In other words, in the past, when a fire broke out in a place where there was only a narrow passageway, such as an alleyway in a residential area, a commercial building, or a department store, a large fire truck would enter an accessible area, and then a firefighter would run to the scene of the fire with a fire hose connected to the fire truck or a fire hydrant and spray water to put out the fire. However, there was a problem in that it took too much time for the firefighter to avoid various obstacles in the narrow passageway, such as an alleyway, and carry the heavy fire hose to the scene of the fire, so there were many cases where the initial put-out failed.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and these embodiments are provided only to make the disclosure of the present invention complete and to fully inform a person having ordinary skill in the art of the scope of the invention. In the drawings, the same reference numerals refer to the same elements.

A mobile sprinkler according to a preferred embodiment of the present invention can be moved by a user to a location where sprinkler work is required to provide water for firefighting, agricultural use, etc. Specifically, it can be easily moved to a location where fire trucks have difficulty entering in the event of a fire, an area with rugged terrain, an urban alley with narrow roads, and then receive water from a fire sprinkler truck, a river, a stream, or a water source and spray it around.

Hereinafter, the present invention will be described in detail with reference to examples.

As shown in FIGS. 1 to 3, a mobile sprinkler according to an embodiment of the present invention includes a frame (100), a front wheel (200), a rear wheel (300), a handle (400), and a frame support (500).

Before going into specifics, the mobile sprinkler according to the embodiment of the present invention can be used in situations such as when a supply of fire fighting water is required due to a fire, when a supply of agricultural water is required due to a shortage of agricultural water, etc., by a user manually moving the mobile sprinkler to an appropriate location, and then receiving water from a water source such as a fire sprinkler truck, a river, or a stream, and spraying the water into the surrounding area. In addition, the mobile sprinkler of the present invention is configured to spray water into the surrounding area while maintaining a stably fixed installation state on the target ground, so that a stable spraying state can be maintained even when the user is not located around the mobile sprinkler.

In addition, the mobile sprinkler device according to the present invention can move more easily than a fire truck on unpaved roads, slippery roads, muddy roads, and snowy roads where fire trucks have difficulty entering, and can easily enter fire-related areas where fire trucks cannot enter.

First, the frame (100) is formed by a plurality of frames connected to each other to form a roughly rectangular hexahedron, and a suction pump motor (110) for sucking water from a water source and discharging it at high pressure, an engine (120) for providing power to the suction pump motor (110), and a nozzle (130) for discharging high-pressure water discharged from the suction pump motor (110) to the outside are installed. Here, the nozzle (130) may be replaced with a low-pressure spray nozzle for spraying agricultural water instead of a high-pressure water spray nozzle for fire suppression.

In an embodiment of the present invention, a high-pressure water flow pipe (140) is provided to connect between a suction pump motor (110) and a nozzle (130), and a fire connection port (111) is provided to the suction pump motor (110) to supply water from a water source.

In addition, a loading space (160) is provided in the frame (100) to store a connecting hose (150) connecting a fire hose (111) and a water source. That is, the present invention supplies water from a fire sprinkler, a river, or a stream through a connecting hose (150), and then discharges the water at high pressure through a suction pump motor (110) into a high pressure water flow pipe (140) and sprays the water at high pressure to the outside through a nozzle (130). In addition, when water is supplied from a river or a stream, a water pump may be additionally installed at the end of the connecting hose (150).

In an embodiment of the present invention, the frame (100) is provided with a separate loading space (160) in which the connecting hose (150) can be stored in a coiled state when not in use.

In addition, as shown in FIGS. 1, 2, 5, 7, and 8, a fire hose connection port (142) is provided in the high-pressure water flow pipe (140), and a user can connect a general fire hose to the fire hose connection port (142), drag the fire hose directly to the vicinity of a fire area, and spray water through a fire hose nozzle provided at the end of the fire hose. In this case, the water spraying operation through the nozzle (130) is not performed through a separate valve off, and water is sprayed only through the fire hose nozzle. A separate loading space in which the general fire hose can be loaded is additionally provided in the frame (100).

Next, as shown in FIGS. 3 and 4, a pair of front wheels (200) and a pair of rear wheels (300) are installed at the bottom of the frame (100). In an embodiment of the present invention, the pair of front wheels (200) are installed so that the gap between them can be variably adjusted.

Specifically, a pair of front wheels (200) can move with the distance between them reduced as needed, for example, in a state where they come closest to each other, in which case it is possible to move more easily along narrow roads, narrow farm roads, etc. To elaborate, as shown in FIG. 4(b), a user moves a pair of front wheels (200) to come as close to each other as possible, and as shown in FIG. 5, by holding the handle (400) described later with his/her hand and lifting the frame (100) so that the rear wheel (300) is separated from the ground, he/she can quickly/easily move on a narrow road using only the front wheels (200). In other words, it can be moved by converting into a one-wheeled handcart structure.

In an embodiment of the present invention, a pair of rear wheels (300) may be installed in a rotatably manner at the bottom of the frame to facilitate direction adjustment. That is, a bracket for fixing a pair of rear wheels (300) is installed at the bottom of the frame (100), and the bracket is installed in a rotatably manner at the bottom of the frame (100) to freely adjust the inclination angle between the direction of movement (longitudinal direction) of the rear wheels (300) with respect to the longitudinal direction of the frame (100).

Next, as shown in FIGS. 3 and 4, a pair of first and second front wheels (210, 220) are each coupled to a front wheel block (230), and the front wheel block (230) is provided so that its positional movement is variable on the frame (100).

To this end, a gap adjustment unit (600) is provided in the frame (100) to adjust the gap between a pair of first and second front wheels (210, 220) and a front wheel block (230) to which the first and second front wheels (210, 220) are respectively fixed.

Specifically, the gap adjustment unit (600) includes a gap adjustment rotary rod (610), a rotary lever (620), and a guide rod (630).

As illustrated in FIG. 4, the gap-adjusting rotary shaft (610) is rotatably provided at the front of the frame (100), and first and second screw threads (611, 612) in different directions are formed on both sides of the center thereof. For example, the first screw thread may be a left-hand screw thread, and the second screw thread may be a right-hand screw thread. Here, the first and second front wheels (210, 220), i.e., a pair of front wheel blocks (230), are formed with corresponding screw threads on the inner surface of the through hole so that they are screw-coupled to the portions where the first and second screw threads (611, 612) are formed, respectively. Both ends of the gap-adjusting rotary shaft (610) are rotatably supported on the frame via bearings or the like.

The rotary lever (620) is provided on one side of the interval adjustment rotary rod (610) to allow the user to rotate the interval adjustment rotary rod (610) in one direction or the other while holding it with his/her hand.

The guide rod (630) is fixed to the frame (100) at a distance from the spacing adjustment rotary rod (610), and both ends are fixed to the frame in a state parallel to the spacing adjustment rotary rod (610).

In an embodiment of the present invention, a through hole is formed in a pair of front wheel blocks (230) so that a gap adjustment rotary rod (610) and a guide rod (630) pass through them, respectively, and a screw thread is formed in a portion where the gap adjustment rotary rod (610) is screw-connected, while a screw thread is not formed in the through hole through which the guide rod (630) passes through. Through this coupling structure, when the rotary lever (620) rotates forward and backward, the pair of front wheel blocks (230) can reciprocally move along the length of the gap adjustment rotary rod and the guide rod in a direction in which they approach or move away from each other while being guided by the guide rod (630).

Accordingly, as described above, the user rotates the rotary lever (620) to move a pair of front wheels (200) as close to each other as possible, holds the handle (400) described below with his hand, and lifts the frame (100) up so that the rear wheels (300) are separated from the ground, thereby enabling the user to move quickly and easily on a narrow road using only the front wheels (200).

Next, as shown in FIGS. 1 and 2, the handle (400) is formed in an approximately 'ㄷ' shape, including first and second handlebars (410, 420) spaced apart from each other and a connecting bar (430) connecting the ends of the first and second handlebars (410, 420).

Here, the central portions of the first and second handlebars (410, 420) are provided to be hinge-rotatable via a hinge axis or the like at the rear upper portion of the frame (100).

Accordingly, as illustrated in FIG. 1, the user may, for example, place the handle (400) approximately parallel to the rear side of the frame (100), hold the connecting bar (430) portion with his or her hand, and use it to push or pull the frame (100) to move it. As another example, as illustrated in FIG. 2, the user may rotate the first and second handlebars (410, 420) of the handle (400) to approximately parallel to the upper portion of the frame (100), and then hold the ends of the first and second handlebars with both hands, and then lift the frame (100) so that the rear wheel (300) is separated from the ground as described above, and use it to quickly and easily move on a narrow road using only the front wheel (200).

In the latter case, the first and second handlebars (410, 420) may partially contact the upper portion of the frame (100) and thus be restricted from further downward rotation.

Meanwhile, in the former case, especially when the connecting bar (430) is held by hand and the frame (100) is pushed forward (in the direction from the rear wheel to the front wheel) for the purpose of moving, in a situation where the front wheel gets caught on an uneven ground surface, gravel, wheel, etc. and cannot move smoothly, the connecting bar (430) moves further forward due to the action of driving inertia, and the lower portions of the first and second handlebars (410, 420) rotate upward.

In this case, a safety accident may occur in which the user falls or gets injured due to the sudden change in the handlebar position and the front wheel not moving forward. In particular, the probability of such accidents occurring increases in situations where quick movement is required, such as firefighting.

To prevent this, as shown in FIGS. 1, 2, and 6, a handle rotation prevention part (700) is provided on the frame (100) to prevent rotation of the handle (400) when the handle (400) is rotated in a specific posture.

Here, the above-mentioned 'specific posture' means a case where the handle (400) is positioned approximately parallel to the rear side of the frame (100) to move it, as in the former case, as illustrated in FIG. 1.

In an embodiment of the present invention, the handle rotation prevention unit (700) is configured to restrict rotation of the handle by selectively contacting the first and second handle bars (410, 420) by user operation.

Specifically, as shown in FIGS. 1, 2, and 6, the handle rotation prevention part (700) includes a through rod (710) and a catch rod (720).

The through-hole (710) is fixed to the frame (100) and has a through-hole formed along its length inside.

The catch bar (720) is provided on both sides of the through bar (710) so that it can be inserted inward or withdrawn outward. To prevent the catch bar (720) from being completely detached from the through bar when it is withdrawn outward from the through bar, a separate detachment prevention structure is provided between the through bar (710) and the catch bar (720).

Accordingly, the user uses the handle (400) by pulling out a pair of catch bars (720) outward by a certain length or more, as shown in FIG. 1 and FIG. 6(a), with the handle (400) rotated so that the connecting bar (430) is positioned higher than the first and second handle bars (410, 420).

At this time, the lower ends of the first and second handlebars (410, 420) can each come into contact with a pair of catch bars (720), thereby restricting the first and second handlebars from rotating upward.

In an embodiment of the present invention, a buffer cover (not shown) made of a material such as rubber, silicone, or epoxy may be further attached to the outer surface of the catch bar (720) to prevent mutual surface damage from occurring due to contact impact with the first and second handle bars.

The user moves the mobile water sprinkler according to the embodiment of the present invention to a location where spraying of firefighting water or agricultural water is required, and then attaches a connection hose (150) to a fire connection port (111) to receive firefighting water from the fire sprinkler or to receive agricultural water sucked from a water pump installed near a river or stream, and then sprays it at high pressure into the surrounding area through a nozzle (130) or a spray nozzle.

At this time, high-pressure water of considerable pressure is ejected through the nozzle (130), and due to this high-pressure ejection, the frame (100) may not be stably installed and fixed on the target ground and may shake in the left/right/front/backward directions. If this shaking increases rapidly, the mobile water sprinkler vehicle may overturn.

To prevent this, as shown in FIGS. 1 to 3 and FIGS. 7 to 9, the mobile water sprinkler according to the embodiment of the present invention further includes a frame support member (500) that is arranged to be deployable outward from the frame (100) and can support the frame (100) to the ground.

The frame support (500) has a structure that can be folded toward the frame (100) or unfolded outward, and includes first to fourth frame support parts (510, 520, 530, 540) that unfold in four directions from the frame (100).

The first frame support member (510) is rotatably provided on the left side of the front lower portion of the frame (100) and has a first support leg member (511) provided at an end thereof, and the second frame support member (520) is rotatably provided on the left side of the rear lower portion of the frame (100) and has a second support leg member (521) provided at an end thereof.

In addition, the third frame support member (530) is rotatably provided on the front lower right side of the frame (100) and has a third support leg member (531) provided at an end thereof, and the fourth frame support member (540) is rotatably provided on the rear lower right side of the frame (100) and has a fourth support leg member (541) provided at an end thereof.

In an embodiment of the present invention, the first to fourth frame supports (510, 520, 530, 540) may each be formed with a structure whose length can be adjusted. For example, they may have a form including an inner tube coupled to the outer tube so that they can be inserted inwardly or withdrawn outwardly along the longitudinal direction of the outer tube and the inner tube.

Therefore, before spraying high-pressure fire water through the nozzle (130), the user can stably fix the frame to the ground by rotating the four first to fourth frame support members (510, 520, 530, 540) outwardly toward the outside of the frame and supporting the first to fourth support legs (511, 521, 531, 541) by making contact with the ground.

Meanwhile, when the mobile water sprinkler according to the embodiment of the present invention is to be installed on a sloped terrain, it is preferable that the frame (100) be installed so that it is entirely horizontal with respect to the horizontal plane in order to maintain stable spraying of high-pressure water.

To this end, the first to fourth supporting legs (511, 521, 531, 541) have a height-adjustable structure so as to be able to adjust the horizontal state of the frame (100).

Specifically, as illustrated in FIG. 9, fastening holes are provided at the ends of the first to fourth frame supports (510, 520, 530, 540) so that the first to fourth support legs (511, 521, 531, 541) can be inserted therein. Screw threads are formed on the inner surface of the fastening holes and screw threads are formed on the outer surface of the first to fourth support legs (511, 521, 531, 541) corresponding thereto. The height of the first to fourth frame supports (510, 520, 530, 540) relative to the ground surface can be adjusted by adjusting the screw-joining position.

As shown in FIG. 1 and FIG. 10, the frame (100) is further provided with a plurality of auxiliary moving bars (170) so that the frame (100) can be lifted and moved while rotating outward and keeping the front wheels (200) and the rear wheels (300) away from the ground.

To elaborate, since it is not easy to move on wheels on uneven surfaces such as gravel roads, when moving on such rough terrain, multiple workers can quickly move the frame by holding the auxiliary moving bar (170) with their hands and keeping the frame away from the ground. The auxiliary moving bar (170) is rotatably connected to the frame (100) through hinge rotation, and at least one can be provided on each of the left and right sides of the frame (100).

While the present invention has been illustrated and described with reference to preferred embodiments for illustrating the principles of the present invention, the present invention is not limited to the exact construction and operation as illustrated and described. Rather, it will be readily apparent to those skilled in the art that numerous changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
