본 발명은 비닐하우스용 하향스프링클러의 낙수비산장치에 관한 것이며 스프링클러에서 용수가 비산되는 과정에서 낙수발생을 해소한 것이다.The present invention relates to a downsplash device for a down-spring sprinkler for a plastic house and solves the occurrence of a downpour during the process of water splashing in the sprinkler.

비닐하우스에서 각종 농작물을 재배할 때 작물에 용수의 공급수단은 비닐하우스의 천정으로 용수관을 설치하고 동 용수관에는 일정간격으로 하향 분사되는 스프링클러를 설치하여 용수관에 용수가 유입되면 수압이 형성되면서 스프링클러로 하향 공급되고 스프링클러의 비산회전체는 유속으로 회전되면서 용수를 하향으로 비산하게 된다.When growing various crops in the plastic house, the water supply means for the crop is to install the water pipe to the ceiling of the vinyl house, and the water pipe is installed with a sprinkler sprayed downward at regular intervals. As it is supplied downward to the sprinkler and the scattering rotor of the sprinkler rotates at a flow rate, the water is scattered downward.

이와 같은 용수공급수단은 용수가 스프링클러로 공급되어 비산회전체에서 비산되면서 비산회전체를 지지하여주는 지지대에 비산되는 용수가 부딪혀 타고 내리면서 물방울이 되어 지면에 떨어지는 낙수가 발생된다.Such water supply means is supplied with a sprinkler water is splashed from the scattering rotating body splashing water splashed on the support for supporting the scattering rotating body is a drop of water falling into the water drops falling on the ground is generated.

이와 같은 낙수는 이는 성장초기의 농작물에는 상처를 주게되어 성장장애로 이어지는 폐단이 있어 낙수발생요인을 해소하기 위한 많은 연구가 되고 있다.Such a drop of water causes damage to crops in the early stages of growth, leading to growth disorders, and many studies have been conducted to solve the cause of falling water.

이에 본원은 특허출원제 2003-45114호 비닐하우스용 하향 스프링클러의 낙수비산장치의 도1과 같이 스프링클러본체(a)내에 위치되는 회전비산체(b) 하방으로 비산회전판(c)을 구비하여 용수가 스프링클러의 비산회전체(b)로 유입되어 용수의 흐름방향을 따라 회전되면서 비산이 이루어지고 지지대(d)에 부딪혀 흘러내리는 낙수는 비산회전판(c)으로 유도되어 비산이 이루어지게 되나, 이는 비산회전체(b)가 회전되면서 비산되는 용수가 지지대(d)에 부딪혀 지지대(d)를 타고 내리는 낙수는 비산회전판(C)으로 유도되지 못하고 지면으로 낙하되므로서 낙수발생을 완전히 해소되지 못하고 있다.Thus, the present application is provided with a scattering rotating plate (c) below the rotating scattering body (b) located in the sprinkler body (a) as shown in FIG. The falling water flowing into the scattering rotor (b) is rotated along the flow direction of the water and the falling water hit by the support (d) is guided by the scattering rotating plate (c) to be scattered, but this is the scattering rotor (b) Rotating as the water splashes while supporting the support (d) falling down the support (d) is not guided to the scattering rotating plate (C) and fall to the ground does not completely eliminate the occurrence of falling water.

또 비산회전판(c)의 축이 스프링클러본체(a)를 구성하는 하부받침대(e) 선단의 절개홈(f)에 끼워지는 수단이어서 비산회전체(b)의 회전시 진동이 발생되어 원활한 회전이 이루어지지 못하는 결점도 함께 수반되고 있다. In addition, the shaft of the scattering rotating plate (c) is a means for fitting into the cutting groove (f) at the tip of the lower base (e) constituting the sprinkler body (a), so that the vibration is generated when the scattering rotating body (b) is rotated to achieve smooth rotation. There are also defects that cannot be supported.

이에 본 발명은 종래의 제반결점을 해소하고 비산회전체에서 용수가 비산되어 스프링클러 본체의 지지대에 부딪혀 타고 내리는 낙수를 낙수유도판에서 모아 낙수비산판으로 유도하고, 비산회전체의 축 저부에 요홈을 형성 낙수비산판의 축을 수직으로 결합하여 스프링클러의 제조를 간편히 하고 비산회전체의 회전시 진동이나 저항을 최소화함에 목적을 두고 있다.Accordingly, the present invention solves the conventional drawbacks, water is splashed from the scattering rotor, the falling water hits the support of the sprinkler body to collect the downfall from the downflow guide plate to guide the downsplash plate, to form a recess in the shaft bottom of the scattering rotor The purpose is to simplify the manufacture of the sprinkler by minimizing the axis of the scattering plate and to minimize the vibration or resistance during the rotation of the scattering body.

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

본 발명에서 스프링클러본체(2)의 상부에는 지지관(2a)을, 일측 하방으로는 지지대(3)를, 하방에는 낙수유도판(4)을, 하부받침대(3a) 선단에는 비산회전체 지지관(5)을 각 형성하여 합성수지재를 성형사출로 제조하게 되면 스프링클러 본체(2)를 양산제조가 가능하게 된다.In the present invention, the upper portion of the sprinkler body 2, the support pipe (2a), one side down the support (3), the downspout guide plate (4), the lower support (3a) tip of the scattering rotor support tube ( 5) by forming each synthetic resin material by molding injection, it is possible to mass-produce the sprinkler body (2).

또 비산회전체(6)는 지지축(6a)의 중심에 삽입홈(7)을 형성하여 합성수지재를 성형 사출로 양산제조가 가능하게 되고, 또 비산회전판(8)은 상부 중심으로 축(8a)을 형성하여 합성수지재를 성형사출로 양산제조할 수 있게 된다.In addition, the scattering rotor 6 forms an insertion groove 7 at the center of the support shaft 6a, so that the synthetic resin material can be mass-produced by molding injection, and the scattering rotor 8 is the upper center shaft 8a. Forming the synthetic resin material can be produced in mass production by injection molding.

이와 같이 스프링클러 본체(2)와, 비산회전체(6)와, 비산회전판(8)을 성형사출로 제조하고, 스프링클러 본체(2)의 상부지지관(2a)과 하부받침대(3a) 선단의 비산회전체 지지관(5) 사이에 비산회전체(6)를 끼우고 비산회전판(8)의 중심축(8a)을 스프링클러 본체(2) 하부 받침대(3a) 선단의 비산회전체 지지관(5)을 통하여 수직으로 끼워 비산회전체(6)의 지지축(6a)의 중심삽입홈(7)에 압입시켜 결합하면 도3과 같이 조립이 이루어지게 되므로 제조가 용이하게 된다.In this way, the sprinkler body 2, the scattering rotating body 6, and the scattering rotating plate 8 are manufactured by molding injection, and the scattering rotating body at the tip of the upper support pipe 2a and the lower support 3a of the sprinkler body 2 is formed. The scattering rotor 6 is sandwiched between the supporting tubes 5, and the central shaft 8a of the scattering rotor 8 is vertically passed through the scattering rotor support tube 5 at the tip of the sprinkler body 2 lower pedestal 3a. If the fitting is pressed into the center insertion groove (7) of the support shaft (6a) of the scattering rotating body (6), the assembly is made as shown in FIG.

이와 같이 조립된 스프링클러 본체(2)의 상부지지관(2a)에 접속관지지대(1)의 하부 연결구를 끼우고 접속관 지지대(1)의 상부에 위치하는 접속관 연결구(11)에 용수관에서 분기되어진 접속관을 끼워서 설치 사용하게 된다.Insert the lower end of the connection pipe support 1 into the upper support pipe 2a of the sprinkler body 2 assembled as described above, and the water pipe to the connection pipe connection 11 located at the upper part of the connection pipe support 1. It is installed by inserting branched connection pipe.

즉 용수관의 용수가 접속관을 통하여 접속관지지대(1)와 스프링클러본체(2)의 상부지지관(2a)으로 유입되면 동 용수는 비산회전체(6)의 중심으로 공급되고 용수의 통로를 따라 유도되면서 비산회전체(6)는 회전되면서 용수가 비산되며 비산회전체(6)의 지지축(6a)과 결합된 비산회전판(8)도 함께 회전된다.That is, when water from the water pipe flows into the connection pipe support 1 and the upper support pipe 2a of the sprinkler body 2 through the connection pipe, the water is supplied to the center of the scattering rotor 6 and along the water passage. While being guided, the scattering rotor 6 rotates while the water is scattered, and the scattering rotor 8 coupled with the supporting shaft 6a of the scattering rotor 6 is also rotated.

이 때 비산되는 용수가 스프링클러 본체(2)의 지지대(3)에 부딪히게 되면 물방울이 형성되어 하방으로 타고 내리거나 떨어지는 낙수는 낙수유도판(4)을 타고 비산회전판(8) 위에 낙하되면서 비산회전판(8)의 원심력에 의해서 비산이 이루어지게 된다.At this time, when the water splashed hits the support 3 of the sprinkler body 2, water droplets are formed, and the falling water falling or falling downwards falls on the scattering plate 4 while flying on the scattering plate 8. The scattering takes place by the centrifugal force of (8).

이와 같이 하향스프링클러에서 용수가 비산회전체(6)로 유입되어 회전되면서 비산되는 용수가 스프링클러 본체(2)를 구성하는 지지대(3)에 부딪혀 지지대(3)를 타고 내리는 낙수는 물방울이 되어 낙수유도판(4)으로 떨어지고 낙수유도판(4)으로 떨어진 낙수는 비산회전판(8)에서 비산이 이루어지게 되므로 물방울이 농작물이나 지면으로 떨어지는 낙수가 없어지게 되므로 낙수로 인한 농작물의 성장장애 요인을 해소할 수 있게 된다.As the water flows from the downward sprinkler into the scattering rotor 6 and rotates, the falling water hits the support 3 constituting the sprinkler body 2 and falls down on the support 3 to become a drop of water. Falling down to (4) and falling down to the downfall induction plate (4) will be scattered from the scattering rotating plate (8), so that drops of water falling on the crops or the ground will be eliminated. Will be.

Therefore, vibration or frictional resistance is minimized.

또 본 발명은 도4 및 도5에서와 같이 접속관 지지대(1)와 스프링클러본체(2) 사이에 원통관(21), 밸브(22), 스프링(23), 스프링지지관(24)을 차례로 결합하여 구성되는 낙수방지용 밸브(20)를 결합하여 사용하게 되면 용수관의 용수공급 초기에 용수압력이 형성되는 시점과 용수공급이 완료되어 용수압력이 떨어지는 시기에 발생되는 적은양의 용수가 비산회전체(6)로 공급되지 않도록 자동차단하는 기능으로 용수의 공급과 중단과정에서 발생되는 낙수현상을 해소할 수 있게 된다.In addition, in the present invention, as shown in Figs. 4 and 5, the cylindrical tube 21, the valve 22, the spring 23, and the spring support tube 24 are sequentially disposed between the connecting tube support 1 and the sprinkler body 2. When combined with the fall prevention valve 20 configured to be combined, a small amount of water generated when the water pressure is formed at the initial stage of the water supply of the water pipe and when the water pressure drops due to the completion of the water supply (6) It is a function to cut off the water supply, which can solve the fall phenomenon caused by the supply and interruption of water.

이와 같이 본 발명은 용수관의 용수가 하향 스프링클러로 공급되어 비산될 때 비산되는 용수가 스프링클러 본체의 지지대에 부딪혀 지지대를 타고 내리는 낙수가 낙수유도판에 의해 비산회전판으로 유도 비산시키게 되므로서 낙수발생을 해소할 수 있게 되고, 또 스프링클러의 제조와 조립이 간편하게 되고 진동과 저항을 최소화시킬 수 있게 되는 것이다.As such, the present invention, when the water from the water pipe is supplied to the downward sprinkler and splashed, the falling water hits the support of the sprinkler body and falls down on the support so that the falling water is guided to the scattering plate by the dripping guide plate. It can be eliminated, and the sprinkler can be manufactured and assembled easily, and vibration and resistance can be minimized.

이상과 같이 본 발명은 스프링클러 본체의 지지대에 낙수유도판을 구비하고 하부받침대에는 비산회전체 지지관을 구비하고, 비산회전체의 지지축 중심에는 삽입홈을 구비하여 비산회전판의 상부 중심으로는 축을 구비하여 제조하므로서 제조가 용이하고 조립이 간편하여 사용시에는 스프링클러 본체에 부딪혀 발생되는 낙수가 낙수유도판에 의해 비산회전판으로 공급 비산되어 낙수발생이 해소되는 특징이 있다.As described above, the present invention is provided with a drop guide plate on the support of the sprinkler body, the lower support base is provided with a scattering body support tube, and the support shaft of the scattering body has an insertion groove in the center of the scattering plate and has an axis as an upper center of the scattering plate.
