본 발명은 제철소에 설치된 철구조물에는 영향을 미치지 않으면서 오염된 도로의 세척이나 살수를 원활하게 수행할 수 있도록 개선된 변동수압에 대한 유효살 수거리 제어용 레인건에 관한 것이다.The present invention relates to an effective spraying range control raingun for an improved variable pressure so as to smoothly perform the cleaning or watering of contaminated roads without affecting the steel structure installed in the steelworks.

일반적으로 제철산업은 거대한 장치산업으로서 집중적인 철골구조로 설치되고, 그 철골구조는 원료수송에 의해 각종 분진이나 오염물질이 발생하는 관계로 자체설비와 도로 등에 오염이 발생하게 된다.In general, the steel industry is a huge equipment industry, which is installed in an intensive steel structure, and the steel structure is polluted to its own facilities and roads because various dusts or pollutants are generated by raw material transportation.

특히, 제철소의 원료공정에서 수입, 불출하는 철광석, 부원료 및 원료탄은 하역과 저장, 불출작업시 많은 먼지가 비산된다.In particular, iron ore, subsidiary materials and coal briquettes imported and discharged in the raw material processing of steel mills are scattered with a lot of dust during unloading, storage and discharging operations.

이렇게 비산되는 먼지를 최소화하고자 설치된 공해방지 설비중의 하나가 도로 레인건(RAIN GUN)이다.One of the pollution prevention facilities installed to minimize this scattered dust is the RAIN GUN.

그런데, 도 1에 도시한 종래 레인건(1)은 어댑터(ADAPTER)(2)의 분사구만 노즐(3)의 구경보다 작은 구조를 갖도록 하여 살수시 살수용수(4)가 최대거리까지 분사되도록 하고 있는데 분사거리를 제어하는 장치가 없어 수압이 너무 강할 때에는 도로의 주변 설비(5)까지 분사되어 설비(5)의 부식을 촉진하는 단점을 유발하게 된다.However, the conventional rain gun 1 shown in FIG. 1 has only the injection hole of the adapter (ADAPTER) 2 to have a structure smaller than the diameter of the nozzle 3 so that the spraying water 4 is sprayed to the maximum distance when spraying water. When there is no device for controlling the injection distance is too strong water pressure is injected to the peripheral equipment (5) of the road to cause the disadvantage of promoting the corrosion of the equipment (5).

본 발명은 상술한 종래 레인건이 갖는 제반 문제점을 감안하여 이를 효과있게 해결할 수 있도록 개선한 것으로, 살수중 수압변동에 의해 수압이 강해졌을 때 어댑터 내의 유량제어판과 수압흡수 텐션스프링을 작동시켜 분사구까지 분출되는 살수량을 조정하도록 하여 수압을 감소시킴으로써 살수거리를 줄여 주변설비로의 비산을 방지할 수 있도록 한 변동수압에 대한 유효살수거리 제어용 레인건을 제공함에 그 목적이 있다. The present invention has been improved to solve the above problems in consideration of the above-mentioned conventional rain gun, when the water pressure is increased by the water pressure fluctuations during the spraying to operate the flow control plate and the water absorption tension spring in the adapter to eject to the injection hole The purpose of the present invention is to provide an effective spraying distance control raingun for variable water pressure to reduce the spraying distance by adjusting the amount of spraying to reduce the spraying distance to prevent scattering to the surrounding equipment.                         

본 발명의 상기한 목적은 살수분사구와 일체로 형성되고 하단이 개방된 절두원추형상을 갖는 하우징과, 상기 하우징의 하단을 밀폐하도록 나사체결되는 접속부재와, 상기 하우징에 수압에 따라 전후진가능하게 내장되어 물의 유로를 가변시키는 상기 하우징과 유사한 형상의 유량제어판으로 구성된 어댑터를 레인건의 노즐 단부에 체결하여서 이루어진 것을 특징으로 하는 변동수압에 대한 유효살수거리 제어용 레인건을 제공함에 의해 달성된다.The above object of the present invention is a housing having a truncated cone shape formed integrally with the sprinkling nozzle and having an open bottom, a connecting member screwed to seal the bottom of the housing, and capable of being moved back and forth according to water pressure in the housing. It is achieved by providing an effective spraying distance control raingun for the variable hydraulic pressure, characterized in that the adapter is made of a flow control plate having a shape similar to the housing that is built to vary the flow passage of water to the nozzle end of the rain gun.

이하에서는, 첨부도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 레인건의 설치 작동상태를 보인 도면이고, 도 3은 본 발명 레인건을 구성하는 어댑터의 분해사시도이며, 도 4는 본 발명 레인건을 구성하는 어댑터의 작동상태도이다.Figure 2 is a view showing the installation and operating condition of the rain gun according to the invention, Figure 3 is an exploded perspective view of the adapter constituting the raingun of the present invention, Figure 4 is an operating state diagram of the adapter constituting the raingun of the present invention.

도 2에 따르면, 본 발명은 레인건(1)의 노즐(3) 단부에 구조 개선된 어댑터(20)를 결합시켜 수압의 변동에 따라 살수용수(4)의 살수거리를 조절토록 함으로써 과다 분사에 의한 도로 주변 설비(5)로의 살수용수(4) 분사를 막을 수 있도록 한 것이다.According to FIG. 2, the present invention combines the adapter 20 having the structural improvement to the end of the nozzle 3 of the rain gun 1 to adjust the watering distance of the watering water 4 according to the fluctuation of the water pressure. It is to be able to prevent the spraying water 4 to the road peripheral equipment (5).

본 발명의 레인건(1)을 구성하는 어댑터(20)는 도 3의 도시와 같이, 레인건(1)과 동일재질로 이루어지고 상단이 절단된 원추형상을 갖는 하우징(22)과, 상기 하우징(22)에 내장되어 탄성적으로 유동되는 유량제어판(40)으로 구성된다.The adapter 20 constituting the rain gun 1 of the present invention, as shown in Figure 3, the housing 22 made of the same material as the rain gun 1 and having a conical shape cut in the upper end, and the housing It is composed of a flow control plate 40 that is embedded in the (22) to flow elastically.

상기 하우징(22)의 끝단에는 살수분사구(24)가 구비되고, 상기 살수분사구(24)와 일체로 연결된 중앙부(26)는 내측에 살수조절용 상기 유량제어판(40)을 포함하는 관계로 상기 살수분사구(24) 보다 외경이 넓은 단층으로 형성되어 있으며, 그 중 상부는 좁고 하부는 넓은 형상으로 테이퍼지게 형성된다.The spraying nozzle 24 is provided at the end of the housing 22, and the central portion 26 integrally connected to the spraying nozzle 24 includes the flow control plate 40 for controlling the spraying water inside the spraying nozzle 24. (24) The outer diameter is formed in a single layer having a larger outer diameter, of which the upper portion is narrower and the lower portion is formed to be tapered in a broad shape.

상기 하우징(22)의 살수분사구(24) 대향단에는 하우징(22)의 하측을 밀폐하는 접속부재(28)가 볼트(30)에 의해 분해가능하게 체결된다.At the opposite end of the water spray nozzle 24 of the housing 22, a connection member 28 for sealing the lower side of the housing 22 is detachably fastened by the bolt 30.

아울러, 상기 접속부재(28)의 돌출부 내면에는 나사산(32)이 형성되어 있어 레인건(1)의 노즐(3) 단부가 나사결합되도록 구성된다.In addition, the thread 32 is formed on the inner surface of the protruding portion of the connection member 28 so that the end portion of the nozzle 3 of the rain gun 1 is screwed.

상기 유량제어판(40)은 상부가 절단된 원추(뿔)모양으로 형성되며, 중앙에는 슬라이딩홀(42) 두개가 쌍을 이루어 측면쪽에 대칭으로 형성되고, 물의 압력을 전달받기 위하여 물이 유입되는 부위의 유량제어판(40) 면에는 분화구처럼 오목한 형상을 갖도록 형성되며, 재질은 가벼운 알루미늄으로 하여줌이 바람직하다.The flow control plate 40 is formed in the shape of a cone (corn) cut at the top, two sliding holes 42 are formed in the center symmetrically formed on the side, the portion where water is introduced to receive the pressure of the water The flow control plate 40 is formed to have a concave shape like a crater, the material is preferably made of light aluminum.

즉, 상기 어댑터(20)는 살수분사구(24)와 일체로 형성된 중앙부(26)를 갖는 하우징(22)과, 상기 하우징(22)의 중앙부(26)에 나사체결되는 접속부재(28)와, 상기 하우징(22)에 유동가능하게 내장되는 유량제어판(40)으로 구성된다.That is, the adapter 20 has a housing 22 having a central portion 26 integrally formed with the sprinkling nozzle 24, a connecting member 28 screwed to the central portion 26 of the housing 22, It is composed of a flow control plate 40 that is embedded in the housing 22 to flow.

한편, 상기 유량제어판(40)의 슬라이딩홀(42)을 관통하여 설치되는 한쌍의 슬라이딩가이드(44)가 구비되는 바, 상기 슬라이딩가이드(44)의 일단은 와셔형태의 헤드부(46)가 구비되어 상기 유량제어판(40)의 이탈을 방지하여 주고, 타단은 나사산(48)이 가공되어 상기 슬라이딩홀(42) 및 하우징(22)의 살수분사구(24) 인접 상면을 관통한 후 그 외측에서 너트(54)에 의해 체결된다.Meanwhile, a pair of sliding guides 44 provided through the sliding holes 42 of the flow control plate 40 are provided. One end of the sliding guide 44 is provided with a washer-type head 46. To prevent separation of the flow control plate 40, and the other end of the thread 48 is processed to penetrate the upper surface adjacent to the spray hole 42 of the sliding hole 42 and the housing 22, and then the nut from the outside thereof. Fastened by 54.

이때, 상기 슬라이딩가이드(44)의 단부가 관통되는 하우징(22)의 내면에는 이와 면접되고 상기 슬라이딩가이드(44)에 끼워진 스토퍼(52)가 구비되며, 또한 상기 스토퍼(52)에 걸림되고 상기 유량제어판(40)의 일측면 외측에 걸림되면서 상기 슬라이딩가이드(44)에 개재된 텐셔스프링(50)도 구비된다.At this time, the inner surface of the housing 22 through which the end of the sliding guide 44 penetrates is provided with a stopper 52 which is interviewed with and fitted to the sliding guide 44, and is caught by the stopper 52 and the flow rate. A tensioner spring 50 interposed in the sliding guide 44 is also provided while being caught outside one side of the control panel 40.

아울러, 상기 하우징(22)이 갖는 테이퍼 경사각(a1)은 상기 유량제어판(40)이 갖는 테이퍼 경사각(a2) 보다 크게 하여 상기 유량제어판(40)이 수압에 의해 전후진될 때에 살수분사구(24) 측으로 배출되는 물의 양을 조절할 수 있게 된다.In addition, the taper inclination angle a1 of the housing 22 is larger than the taper inclination angle a2 of the flow control plate 40 so that the flow control plate 40 is moved forward and backward by hydraulic pressure. The amount of water discharged to the side can be adjusted.

즉, 상기 하우징(22)과 유량제어판(40)이 갖는 경사각(a1,a2)이 다르게 형성됨과 동시에 상기 하우징(22)의 경사각(a1)이 더 크므로 유량제어판(40)이 살수분사구(24)측으로 전진되었을 때에는 물의 유로를 작게하고, 후진되었을 때에는 물의 유로를 크게 하므로 수압변동에 따라 살수분사구(24)를 통해 분사하는 물의 양을 조절할 수 있게 된다.That is, since the inclination angles a1 and a2 of the housing 22 and the flow control plate 40 are formed differently, and the inclination angle a1 of the housing 22 is larger, the flow control plate 40 is a spraying nozzle 24. When it is advanced to the side side, the water flow path is reduced, and when it is reversed, the water flow path is increased, so that the amount of water sprayed through the spraying port 24 can be adjusted according to the hydraulic pressure fluctuation.

이러한 구성으로 이루어진 본 발명은 다음과 같이 작동된다.The present invention made up of such a configuration works as follows.

도 4를 참조하면, 수압의 최대와 최소의 범위에서 살수가 실시되는 작동도로서 (가)는 최소작용으로 수압이 낮은 상태를 예시한 것이다.Referring to Figure 4, as the operating water spraying in the maximum and minimum range of the water pressure (A) illustrates a state of low water pressure with a minimum action.

이때에는 어댑터(20)로 유입되는 물의 양이 작아 이때 상기 유량제어판(40)에 작용하는 수압이 낮아 텐션스프링(50)을 압축하지 못하므로 도시와 같이 유량제어판(40)은 탄력작용을 하지 않는 상태에 있게 되고, 물의 유로(L)는 넓어 충분한 양의 물이 살수분사구(24)를 통해 배출되게 된다.At this time, since the amount of water flowing into the adapter 20 is small, the water pressure acting on the flow control plate 40 is not so low that the tension spring 50 cannot be compressed, and thus the flow control plate 40 does not have elasticity. It will be in the state, the water flow path (L) is wide so that a sufficient amount of water is discharged through the sprinkling nozzle (24).

(나)의 도시와 같이, 수압변동에 의하여 수압이 상승되기 시작하면 상승된 수압은 유량제어판(40)의 상부면에 형성된 오목한 부위에 집중되면서 그 힘으로 상기 유량제어판(40)을 밀게 되고, 그 힘이 텐션스프링(50)의 팽창력보다 커지는 순 간 상기 유량제어판(40)은 슬라이딩가이드(44)를 따라 하우징(22)의 살수분사구(24)측으로 전진되게 된다.As shown in (b), when the hydraulic pressure starts to rise due to the hydraulic pressure fluctuation, the increased hydraulic pressure is concentrated on the concave portion formed on the upper surface of the flow control panel 40, and the pressure control panel 40 is pushed by the force. As soon as the force is greater than the expansion force of the tension spring 50, the flow control plate 40 is advanced toward the water spray nozzle 24 of the housing 22 along the sliding guide 44.

동시에, 테이퍼진 경사각 차이에 의해 물의 유로(L)는 좁아지게 되므로 분사량이 줄어들어 살수범위가 좁아지게 된다.At the same time, the water flow path L is narrowed due to the tapered inclination angle difference, so that the amount of spraying is reduced and the spraying range is narrowed.

이로써, 수압변동에 적극적으로 대응하여 살수범위를 자동 조절토록 함으로써 설비밀집지역이나 야드의 살수제한구역 같은곳에서 용이하게 활용할 수 있다.Thus, by actively responding to the water pressure fluctuations to automatically adjust the spraying range can be easily utilized in places such as equipment confined area or yard spray limit.

이상에서 상세히 설명한 바와 같이, 본 발명은 수압의 변동에 따라 유량제어판과 텐션스프링의 작동에 의해 물의 유로를 가변시킴으로써 살수범위를 자동조절하므로 수동조작이 필요 없고, 살수거리를 조절할 수 있어 도로 주변설비의 부식 촉진을 방지하는 효과를 제공한다.As described in detail above, the present invention automatically adjusts the watering range by varying the flow path of the water by the operation of the flow control plate and the tension spring in accordance with the change in the water pressure, there is no need for manual operation, the watering distance can be adjusted, road peripheral equipment Provides the effect of preventing corrosion promotion.
