 The present invention relates to a portable high-pressure water injector, and more particularly, to carry a high-pressure water injector including a small engine, a pump and a hose while moving to a high forest fire occurrence point, highlands or vast farmland The present invention relates to a portable high-pressure water injection device that facilitates the early fire extinguishing or water cycle (pesticide spraying) work by supplying and spraying water at high pressure.

Generally, forest fire extinguishing pumps or agricultural pumps that can inject water or pesticides include underwater or ground motor pumps and engine pumps that require electricity.

However, since the motor pump using the electricity has to draw electricity into a wildfire occurrence area or farmland, it is difficult to install the electric wire, and in the case of the engine pump, a mobile vehicle equipped with an engine is required. There was an inconvenience in using the vacuum pressure. These pumps have a problem that they are not portable because they are bulky and heavy.

In addition, when a drought or pesticide is sprayed using a motor pump or an engine pump, or a wildfire occurs near a house or a road, electricity can be supplied to spray (spray) water or pesticides as a motor pump, and a fire engine Early evolution can be achieved by using a vehicle equipped with a pump, but water supply and spraying of pesticides are not urgent, but in a mountainous high forested area, a vehicle equipped with a fire engine pump may enter to prevent electricity supply. Most of the time, it is difficult to evolve early, leading to large forest fires. In order to extinguish the fire, water is dropped through the helicopter, and firefighters approach the place where the fire broke out and use portable equipment.

The water dropping method using the helicopter is used to remove large embers by dropping water in a forest fire, but it is expensive helicopter equipment to remove the remaining embers can not drop the water indefinitely because the purpose of the firefighters Evolution is carried out using a portable device such as a backpack sprinkler, a fire extinguisher, a shovel or an axe, approaching a site of ignition.

Each of the fire extinguishing equipment possessed by each of the above-mentioned fire-fighting agents is approached about 1 to 2 meters and then fired directly by spraying water or fire extinguishers. The use of shovels and fire extinguishers once used, it is almost difficult to recharge in the mountains, so it is practically useless. However, it is dangerous for the Evolution Agent to shovel close to the fires of fire, and it is very inefficient to extinguish the fire that spreads when a person is exhausted.

Fire extinguishing fire among the fire extinguishing equipment can reliably extinguish the remaining embers (消 火) to ensure the safety of the firefighters is the most effective method of spraying water. However, in case of the back pack water sprayer, the fire extinguishing work should be terminated when spraying it for about 5 ~ 10 minutes. In order to solve this problem, Korea Utility Model Registration No. 0268084 “High pressure waterproofing device for acid fire extinguishing” has been proposed.

The high pressure waterproofing device for forest fire extinguishing uses a high pressure piston pump to connect the inlet to the water tank, the outlet of the pump to the distributor, and the distributor and the waterproof gun to the hose, and the general centrifugal pump has low water pressure. Since it is not possible to extinguish the fire of the high place, the effect can be obtained by using the high pressure piston pump which can spray with high water pressure to extinguish the fire ignited in the high point of the mountain at the point of the disaster prevention vehicle.

However, since the high pressure waterproofing device for forest fire extinguishing is configured to operate the pump by the engine power of the disaster prevention vehicle and supply the water stored in the water tank through the pump, if the distance between the road where the disaster prevention vehicle enters and the ignition place is too far and high, Not only was the supply of water impossible, but after all the stored water was exhausted, there was a problem in that even if there was water in a valley or a spring close to the ignition point, the pump could not be operated separately from the disaster prevention vehicle and became useless.

Therefore, the present invention is to solve the above-mentioned problems, a small engine, a pump that can be used directly in the water or above the ground by receiving the power of the small engine, and the high-pressure water supplied from the pump to a predetermined place The present invention is to provide a portable high pressure water jet device which is configured to be sprayed so that it can be used conveniently regardless of location.

In addition, the present invention provides a portable high-pressure water injection device capable of prolonging the life of the pump by adjusting the rotational speed of the portable small engine to the appropriate rotational speed for using a pump that is easy to generate a vacuum pressure have.

In addition, the present invention is not limited to the injection of water or the spraying of pesticides, and to provide a portable high-pressure water injection device suitable for a small amount of pumping operation of the immersion paper that can not be used due to power outages and cleaning of the building exterior wall.

In addition, the portable high pressure water injector of the present invention is capable of operating at a suitable rotational speed for long-term use of a drive unit of a monoplex impeller or piston that does not require water supply of an impeller chamber to generate a high pressure and obtain an initial vacuum force. It may be characterized in that the technical configuration to be made to be mounted directly or separately to the reduction unit to be made.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is an exploded perspective view showing a portable high-pressure water injection device according to the present embodiment, 1 is a small engine, 2 is a connector, 3 is a socket, 4 is a pump, 5 is a reduction unit, 6 is a hose, 7 is Indicates the spray nozzle.

The portable high pressure water injection device of the present invention is an equipment for extinguishing a disaster prevention vehicle through a pump (4) by using a rotary power of a portable small engine (1), such as water supplied from a valley, a fountain, or a helicopter, and artificially prepared pesticides. It is configured to spray water and pesticides necessary for forest fire extinguishing or farming by pumping through a hose (6) to a high mountain or farmland that is not reachable, but with a small engine (1) and a pump (4). ) Is operated while the water supply personnel carry, and the hose 6 and the injection nozzle 7 has an optimized configuration that is used in cooperation by a pair of two people operating while carrying out such as fire extinguishing personnel.

The small engine 1 selects one of ordinary products that can be carried on the back using the suspenders 11 and can generate high-speed rotational force. The small engine 1 rotates at a high speed within a range of 5,000 rpm to 15,000 rpm while the speed is variable according to the operation of the engine acceleration lever 13 mounted to the connecting pipe 2. In addition, the flexible wire 21 is fixed to the socket portion (3) which is part of the output end 22 is coupled to the pump (4) while being covered and protected by the connecting pipe (2) to rotate the pump (4) do.

As shown in FIGS. 2 and 3, the socket part 3 has a vertically cut fastening tube 31 fixed to prevent flow or slipping after the connecting pipe 2 of the flexible wire 21 is fitted in the center thereof. It is formed, the output end 22 and one end of the flexible wire 21 is coupled to each other by a bearing or the like so as to be rotatable in the center of the drive shaft 32 receives the rotational force directly, the lower circumference is the body of the pump 4 A plurality of screwing holes are formed integrally with the fixing flange 33 perforated so as to be coupled to the 42.

As an example, the pump 4 accommodates the reduction gear 5 described later as shown in the exploded perspective views and cross-sectional views of FIGS. 2 to 4, and extends below the vertical gear 52 of the reduction gear 5. And a drive body 43 for moving the liquid through the rotation of the shaft 53, and the socket part 3 and the deceleration part 5 are separated while the liquid inlet 45 and the outlet 46 are provided. The cover 41 is coupled to the body 42 and the lower cover 47 for sealing the insertion space of the drive body 43 to prevent it. The cover 41 and the lower cover 47 are partitioned so as to accommodate the reduction unit 5 and the driving body 43 in the body 42.

The driving body 43 of the pump 4 is a multi-screw type impeller or gear impeller which is operated regardless of the rotational force of the small engine 1. Since it is difficult to supply the liquid for extinguishing wildfires, etc. occurring in the highlands, in the present invention, a vacuum pressure is generated at the inlet 45 using the monoplexed impeller 431 of a rubber material having elasticity as shown in FIG. 4. The discharge pressure is improved by increasing the suction lift and the discharge lift. As another embodiment of the driving body 4, two to four pistons 432 operated up and down by the inclined plate 433 and the spring 434 having a high vacuum pressure are used.

Looking at the result of the embodiment measured by operating in the normal rotation using the drive body 43 of the high-pressure pump 4 as a monoplex impeller 431, the suction head can secure up to 8M and the discharge pressure is also 4 ~ It can be secured up to 6MpaG and the discharge amount can confirm that the amount of 160ℓ per minute can be pumped, and when the drive body 43 of the high-pressure pump (4) is used as the piston 432, the discharge pressure rises to 4 ~ 6MpaG While it can be confirmed that the discharge amount of 6L per minute can be obtained. According to the above results, a sufficient distance for conveying the liquid to the high ground 1,000M required as the fire extinguishing pump can be obtained. In particular, when the piston 432 is used as the driving member 43 of the high-pressure pump 4, the monoplex is used. Since the discharge pressure is higher than that of the impeller 431, it is more suitable for use in the highlands.

However, since the monoplex impeller 431 or the piston 432 used as the driving body 43 of the high-pressure pump 4 is typically rotated at about 1,700 to 2,400 rpm, the desired vacuum pressure and pressure force can be obtained. If the rotational speed of 5,000rpm ~ 15,000rpm generated from the general portable small engine 1 is used as it is, the efficiency of vacuum pressure is lowered as well as a problem of shortening the life of equipment.

Accordingly, the reduction unit 5 is provided to be accommodated in or coupled to the pump 4 so as to adjust the rotation speed of the driving body 43 of the pump 4. The deceleration part 5 is composed of a main gear 51 and a longitudinal gear 52 to which the drive shaft 32 of the socket part 3 is coupled, but the rotational speed transmitted from the small engine 1 is the same as that of the pump 4. Rotating the drive body 43 is made to rotate to decelerate to approximately 1,700 ~ 2,400rpm to prevent the life of the drive body 43 is shortened due to wear and damage caused by overheating. In this embodiment, if the ratio of the main gear 51 and the vertical gear 52 is 1: 2.6 and the rotation of the drive body 43 is maintained at 2,000 ± 200 rpm, the desired optimum pumping operation state can be obtained. there was. In addition, the main gear 51 and the vertical gear 42 of the reduction unit 5 may use a spur gear, an internal gear or a helical gear, and among them, it is most preferable to use a helical gear that minimizes frictional force.

On the other hand, the reduction unit 5 is arranged in the state accommodated above the body 42 of the pump 4, as shown in Figure 3 and the main shaft 32 and the drive shaft 32 of the socket portion 3 fixed to the cover 41 The cover 41 may be formed to be fixed to the pump body 42 so that the 51 is connected, and as shown in FIG. 5, the speed reduction part 5 is integrally formed in the cover 41. When the cover 41 is coupled to the body 42 of the pump 4, the shaft 53 of the longitudinal gear 52 of the reduction unit 5 operates the driving body 43. It can be formed so that. In the case of the structure in which the reduction unit 5 is coupled to the cover 41, the driving body 43 is jointly formed even if each of the monoplex impeller 431 as shown in FIG. 5 or the piston 432 as shown in FIG. It can also be used to provide convenience.

In addition, the inlet 45 of the pump 4 is connected to a conventional tube (not shown) to use the tube in a liquid state or the pump 4 itself is used in a liquid state, and the pump ( The discharge port 46 through which the high pressure water is discharged by the operation of the driving member 43 of 4) is mounted at the end of the hose 6 and the hose 6, one end of which is connected by the socket 61, as shown in FIG. Injection nozzles 7 for spraying are made of interconnected. The hose 6 is to use a small inner diameter of about 5 ~ 10mm, a common bobbin 8 wound around the hose 6 by the amount of 100 ~ 300M length, as shown in Figure 1, and a portable fork member (9), and the hose 6 is extended using a conventional connection socket, not shown.

In addition, the pump (4) is mainly used in the state submerged in the water, the spring or the water tank to be supplied, the distance between the small engine (1) and the pump (4) according to the terrain when receiving water from nature ( If the height) is far away, as shown in Figure 1 by connecting a plurality of connecting pipes 2 it is possible to adjust the distance so that the pump 4 can be submerged in water.

Next, the portable high-pressure water jetting apparatus of the present invention configured as described above will be described through an acid fire extinguishing process having the same method of supplying water or spraying pesticides on highland farmland.

Forest fires are generated in the highlands, water supply personnel carrying small engines (1) and pumps (4), and firefighting personnel carrying hoses (6) and injection nozzles (3) are dispatched in groups of two. First, after arriving at the location of the water tank delivered by the water, fountain or helicopter of the valley located at the shortest distance from the place of the fire, the water supply personnel connects the connecting pipe (2) of the small engine (1) to the socket connected to the pump (4). When the fastening pipe 31 of the part 3 is fixed and fixed, the output end 22 of the flexible wire 21 is fitted to the drive shaft 32 of the socket part 3 to be interlocked. The drive body 43 is ready to rotate.

The firefighter then unscrews a portion of the hose 6 wound around the bobbin 8 of the fork member 9 on his back and inserts a socket 61 into the outlet 45 of the pump 4 to connect it. After immersing the pump (4) in water or put the pipe (not shown) connected to the inlet (45) into the water fire extinguishing personnel will be moved to the fire extinguishing site by loosening the hose (6). Since the hose 6 is 100 ~ 300M length is ready to access even the high mountainous forested forest, and if a forest fire occurred at a far distance, prepare a hose (6) further wound on the bobbin (8) It is possible to extend (6) by joining with a conventional connecting socket.

When the fire extinguishing agent moves while unwinding the hose 6 or after arriving at the fire extinguishing site, the water supply agent operates the small engine 1 and increases the rotational speed of the engine with the engine acceleration lever 13 according to the altitude from 5,000 rpm to 15,000. It will be adjusted to work within rpm. The high speed operation of the small engine 1 immediately leads to the rotation of the flexible wire 21, the flexible wire 21 is to rotate the main gear 51 and the vertical gear 52 of the reduction gear (5), Subsequently, the shaft 53 of the vertical gear 52 decelerates and rotates the driving body 43 of the pump 4 at 1,700 to 2,400 rpm so that the water flowing into the inlet 45 is discharged at a high pressure through the outlet 46. The discharge is supplied to the hose (6).

The monoplex impeller 431 as shown in FIG. 4, which is one of the driving bodies 43 of the pump 4, is rotated to the outlet 46 while evacuating the inlet 45 by the six variable blades, so that water is immediately discharged. The high pressure water is supplied to the hose 6 through the discharge and repeated rotation. In addition, when the inclined plate 433 rotates as shown in FIG. 6, which is one of the driving bodies 43 of the pump 4, the plurality of pistons 432 are sequentially lowered and the lowered piston 432 is connected to the spring 434. As a result, it is possible to discharge the high pressure water in a sequential operation of sequentially rising.

The high pressure water supplied to the hose (6) is delivered to the water spray nozzle (7) connected to the end, and the spray water extinguishing agent can spray from a long distance, so that the fire can be extinguished safely and completely extinguishes even the embers. Will be.

The driving body 43 of the pump 4 is connected to the flexible wire 21 in a straight line to the soget portion 3 that transmits power to the speed reduction portion 5 to enable high-speed rotation without load, water It can deliver up to the summit of high altitudes and can supply water up to about 1,000M, making it suitable for use at high altitudes.

In addition, when the drive body 43 of the pump 4 is used as the monoplex impeller 431 or the piston 432 having excellent vacuum force, it is not necessary to fill the water inside the pump to discharge the initial water, and thus to cope quickly. As shown in Figure 7a and 7b attached can be connected to a large number of hoses 6 of the inner diameter of about 5 ~ 10mm small supply of high pressure water to the fire extinguishing site of the highlands and distant fire extinguishing As a value it has value.

As described above, the water supply personnel managing the small engine 1 and the pump 4 while carrying the water will cooperate to continuously supply the water while checking the remaining water of the valley, the spring, or the water supplied by the helicopter. Fire extinguishing personnel can use the water injection nozzle (7) connected to the end of the hose (6) to inject water at high pressure to the flames and the remaining embers can effectively extinguish the forest fire early by the cooperation.

In addition, the high-pressure water injector of the present invention is not limited to being used in high altitude and rough terrain, and can be used in all fire prevention places where fire-fighting disaster prevention vehicles are difficult to enter, and may be submerged in the small engine 1 and water. Even if the position of the pump 4 is increased, it is understood that by connecting and extending a plurality of connecting pipes 2, it can be adapted to the change of the natural topographical environment.

In addition, since it is possible to supply high pressure water, it is possible to connect a common distribution pipe (not shown) to the end of the hose (6) and connect a plurality of water injection nozzles (7) to evolve a large area at the same time, the hose (6) Combined with a conventional sprinkler at the end of the watering work or spraying of pesticides is made conveniently.

In addition, it is also possible to utilize a small amount of pumping work of the immersion paper, which is impossible to use the electric pump due to the power failure in case of flooding damage, it is revealed that it can be used for washing the outer wall of high-rise buildings and vehicles with high pressure water.
