Description

수압을 이용한 왕복 회전식 방수총 {SPRAY GUN OF COAL PILE}Reciprocating rotating gun using water pressure {SPRAY GUN OF COAL PILE}

발전소의 석탄야적장 및 분진발생지역엔 비산먼지 제거 및 분진억제를 위해 정기적으로 경화액과 물을 혼합하여 뿌려주고 있다. 전기적 동력없이 수압만을 이용하여 반원형태로 왕복 이송하며 물을 뿌려주는 장치에 관한 것이다. Coal yards and dust generating areas of power plants are regularly sprayed with a mixture of hardening liquid and water to remove fugitive dust and control dust. The present invention relates to a device for spraying water by reciprocating in semicircle form using only water pressure without electric power.

기존에 주로 수입되어 사용되고 있는 방수총은 좌우 두 쌍의 블레이드가 별도로 설치되고 방수총 하단의 스프링 장치가 레바를 밀고 당겨 두 쌍의 블레이드 위치를 바뀌게 함으로써 좌우 왕복 이송을 가능케 하였으나 구조가 복잡하고 한쪽 방향으로 이송시 수류의 분출을 완전히 차단하는 구조이므로 연속적인 방수가 되지않고 일 방향 방사만 이루어지며 또한 블레이드에 작용하는 충격력이 한쪽으로만 작용하여 부품의 파손이 잦은 문제점이 있다The existing water gun, which is mainly imported and used, has two pairs of left and right blades installed separately, and the spring device at the bottom of the water gun pushes and pulls the lever to change the position of the two pairs of blades. It is a structure that completely blocks the jet of water flow during transportation, so there is no problem of frequent waterproofing without continuous waterproofing, and the impact force acting on the blade acts only on one side, which causes frequent breakage of parts.

본 발명은 전기전자 장치가 들어가지 않은 기구학적 방수 장치이며 수류에 의한 맥동 회전장치로 설정된 회전 범위 내에서 연속적 방수가 가능하고 방수되는 반원형내의 구역에 방수되는 물의 산포도를 일정하게 하며 보다 단순한 구조의 부품을 사용함으로써 제작비용을 줄이고 또한 파손시 수리가 용이함을 과제로 하였다. The present invention is a kinematic waterproofing device that does not contain an electrical and electronic device, and can be continuously waterproof within the rotation range set by the pulsation rotating device by water flow, and the scattering of water to be waterproofed in the semi-circular area to be waterproofed is constant, The use of parts reduces manufacturing costs and makes repairs easy in case of breakage.

상기 과제를 해결하기 위하여 블레이드(6)를 일체형으로 제작하고 블레이드 앞쪽의 압력판(4)을 상하로 경사지게 하여 수압에 의해 블레이드(6)가 상하로 움직이게 하고 블레이드(6)가 상하로 움직이면서 샤프트 고정축(7)의 샤프트에 원웨이 베어링(10)을 체결시켜 이에 순차적으로 연결된 3차기어(13)를 일방향으로 회전시키고 3차기어(13)에 결합된 켐(8)이 조금씩 회전하면서 로드(9)를 밀고 당기게 함으로써 압력판(4)의 방향을 좌우로 바꾸어 주고 압력판(4)의 방향대로 베이스링크(17) 상단의 방수총 전체가 회전하게 구성한다.In order to solve the above problems, the blade 6 is integrally manufactured, and the pressure plate 4 in front of the blade is inclined up and down so that the blade 6 moves up and down by hydraulic pressure, and the blade 6 moves up and down. The one-way bearing 10 is fastened to the shaft of (7) to rotate the third gear 13 sequentially connected thereto in one direction, and the cam 8 coupled to the third gear 13 rotates little by little. By pushing and pulling), the direction of the pressure plate 4 is changed to the left and right, and the entire waterproofing gun on the top of the base link 17 is rotated in the direction of the pressure plate 4.

또한, 원유 저장소, 사찰 및 산불 방화벽 구축등에 적용하여 자동 소화 장비 로도 적용할 수 있는 장점이 있다.In addition, there is an advantage that can be applied to automatic fire extinguishing equipment by applying to oil storage, temples and forest fire firewall construction.

본 발명에서 수류의 압력을 이용하여 방수총이 좌우로 회전할 수 있도록 한 제작방법은 다음과 같다.In the present invention, the manufacturing method for rotating the waterproof gun left and right using the pressure of the water flow is as follows.

도 1은 방수총의 개략도이며 도 2는 수류가 압력판(4)에 작용하여 방수총이 회전하는 방향을 나타내기 위한 개략도이다.FIG. 1 is a schematic view of a waterproof gun, and FIG. 2 is a schematic view showing a direction in which water flow acts on the pressure plate 4 to rotate the waterproof gun.

도 1에서, 베이스링크(17)를 출수관쪽 플렌지에 연결하고 바디(1)를 베이스링크(17)에 회전가능하게 체결하였다. 샤프트 고정축(7)의 샤프트에 1차기어(11)가 결합된 원웨이베어링(10)을 압입 시키고 2차기어(12)와 3차기어(13)는 블레이드(6)의 외면에 조립하여 1차기어(11)와 연동하게 하였다. 또한, 3차기어(13)에 파이프(2) 방향으로 켐(8)을 부착하여 블레이드(6)에 고정된 스프링(14)이 로드(9)를 켐(8)에 지속적으로 밀착하도록 구성하였으며 이 로드(9)는 좌우 회전 가능한 압력판(4)에 연결하여 켐(8)의 회전에 따라 압력판(4)을 밀고 당겨 압력판(4)의 방향이 바뀌게 구성하였다.In FIG. 1, the base link 17 is connected to the outlet pipe side flange and the body 1 is rotatably fastened to the base link 17. The one-way bearing 10 in which the primary gear 11 is coupled to the shaft of the shaft fixed shaft 7 is press-fitted, and the secondary gear 12 and the tertiary gear 13 are assembled on the outer surface of the blade 6. Interlocked with the primary gear (11). In addition, by attaching the chem (8) in the direction of the pipe (2) to the third gear 13, the spring (14) fixed to the blade (6) is configured to keep the rod (9) in close contact with the chem (8). The rod 9 is connected to the left and right rotatable pressure plate 4 to push and pull the pressure plate 4 in accordance with the rotation of the chem 8 so as to change the direction of the pressure plate 4.

상기한 구성에 의한 동작관계를 이하 상세히 설명한다.The operation relationship by the above configuration will be described in detail below.

노즐(3)을 통하여 토출된 수류(8~10kg/㎠)는 압력판(4)에 부딪치고 도2와 같이 압력판(4)에는 아래쪽 방향의 토오크(c)가 블레이드(6)를 아래로 밀어내고 좌방향의 토오크(a)는 방수총 몸체를 좌 방향으로 일정량 회전시키게 된다.Water flow (8-10 kg / cm 2) discharged through the nozzle 3 hits the pressure plate 4, and as shown in FIG. 2, a downward torque c pushes the blade 6 downward on the pressure plate 4. Torque a in the left direction rotates the waterproof gun body in a predetermined amount in the left direction.

아래로 내려간 블레이드(6)는 무게추(5)에 의하여 다시 위로 올려지고 상기 동작을 반복하게 된다.The lowered blade 6 is lifted up again by the weight 5 to repeat the operation.

블레이드(6)가 상하 왕복운동 할 때 2차기어(12)는 1차기어(11)를 회전시키 게 되나 원웨이 베어링(10)의 특성상 한쪽 방향으로만 회전하기 때문에 블레이드(6)가 위쪽 방향으로 이동할 때는 1차기어(11)가 회전함으로 2차기어(12)는 회전하지 않고 블레이드(6)가 아래쪽 방향으로 이동할 때는 1차기어(11)가 원웨이베어링(10)에 의해 고정됨으로 2차기어(12)만 회전하게 된다. 이에 따라 2차기어(12)는 3차기어(13)를 회전시켜 켐(8)을 일정각도 회전시키게 된다.When the blade 6 reciprocates up and down, the secondary gear 12 rotates the primary gear 11, but because the one-way bearing 10 rotates only in one direction, the blade 6 rotates upward. When the primary gear 11 is rotated when moving to the secondary gear 12 does not rotate, and when the blade 6 moves downward, the primary gear 11 is fixed by the one-way bearing 10 Only the gear 12 will rotate. Accordingly, the secondary gear 12 rotates the third gear 13 to rotate the chem 8 at an angle.

블레이드가 상하 왕복운동을 계속 함으로써 켐(8)을 지속적으로 회전시키게 되고 켐(8)은 로드를 밀고 당김으로써 압력판(4)의 방향을 바꾸게 한다.The blade continuously rotates the chem 8 by continuing the up and down reciprocation motion, and the chem 8 changes the direction of the pressure plate 4 by pushing and pulling the rod.

블레이드(6)가 수회 왕복 운동하여 켐(8)의 원주 방향을 바꾸게 되면 켐(8)의 형상에서 큰 지름의 외경에서 작은 지름의 외경으로 방향이 바뀌고 로드(9)가 압력판(4)의 방향을 바뀌게 한다. 이에 따라 방수총의 회전방향이 좌에서 우로 또는 우에서 좌로 바뀌게 됨으로써 일정 수압(8~10kg/㎠)에서 정해진 기어비에 따라 방수총의 회전각도가 정하여 지도록 하였다.When the blade 6 reciprocates several times to change the circumferential direction of the chem 8, the shape of the chem 8 changes from the outer diameter of the large diameter to the outer diameter of the small diameter, and the rod 9 moves in the direction of the pressure plate 4. To change. Accordingly, the rotation direction of the waterproof gun was changed from left to right or from right to left, so that the rotation angle of the waterproof gun was determined according to the gear ratio determined at a certain water pressure (8 ~ 10kg / ㎠).

또한, 블레이드(6)의 상하 운동으로 압력판(4)이 토출되는 수류를 순간적으로 끊어 줌으로써 연속적이고 고른 물의 산포 밀도를 가지게 하였다.In addition, the water flow discharged from the pressure plate 4 by the vertical movement of the blade 6 is cut off instantaneously to have a continuous and even water dispersion density.

상기한 본 발명은 석탄야적장에 주로 사용하고 있는 방수총 및 스프레이 건의 개선을 위해 발명하였으나 원유 저장소, 사찰등의 화재 방호벽등에 두루 적용 가능 할 것으로 보인다.The present invention described above for the improvement of the waterproof gun and spray gun mainly used in coal yard, but seems to be applicable throughout the fire barriers such as oil storage, temples, etc.

도 1은 본 발명에 따른 방수총의 개략도.1 is a schematic view of a waterproof gun according to the present invention;

도 2는 압력판에 작용하는 수압에 의해 방수총이 회전하는 원리를 보여주기 위한 개략도. Figure 2 is a schematic diagram showing the principle of the waterproof gun rotates by the water pressure acting on the pressure plate.
