도 1은 본 발명에 따른 소하천 부유물 처리시설의 전체적인 구성을 개략적으로 나타낸 개략 구성도이며, 도 2는 도 1에 도시된 소하천 부유물 처리시설의 주요 구성을 확대도시한 평면 구성도이다. 1 is a schematic configuration diagram schematically showing the overall configuration of a small stream floatation treatment facility according to the present invention, Figure 2 is a plan view showing an enlarged main configuration of the small stream floatation treatment facility shown in FIG.

도 1 내지 도 2를 참조하면, 본 발명은 일정구간에 걸쳐 하천(1) 폭을 확장 시켜 형성된 보조수로(10)와, 상기 보조수로(10)가 형성된 하천 중앙에 하천 길이방향을 따라 설치되어 하천(1)을 분할하는 중앙분리옹벽(20)을 구비한다. 1 to 2, the present invention is an auxiliary channel 10 formed by extending the width of the stream (1) over a certain period, and along the longitudinal direction of the river in the center of the stream formed with the auxiliary channel (10) It is provided with a central separation retaining wall (20) for dividing the river (1).

상기 중앙분리옹벽(20) 일측 단부와 타측 단부에는 각각 두개의 구간으로 분할된 수로를 선택적으로 개방 또는 폐쇄하여 물의 흐름방향을 제어하는 작동수문(30)과, 하천을 따라 흘러내려온 하천 부유물 예컨대, 나뭇가지 또는 부유 쓰레기 등을 걸러내기 위한 걸름망(40)이 회동가능하게 설치되며, 상기 작동수문(30) 및 걸름망(40)은 각각 제1 , 제2 제어수단(35)(45)에 의해서 그 회동이 제어된다.At one end and the other end of the central separation retaining wall 20, an operation gate 30 for selectively opening or closing a water channel divided into two sections, respectively, to control the flow direction of water, and a river floating material flowing down the stream, for example, A filtering net 40 for filtering twigs or floating garbage is installed to be rotatable, and the operation gate 30 and the filtering net 40 are respectively supported by the first and second control means 35 and 45. Rotation is controlled.

상기 제1, 제2 제어수단(35)(45)은 작동수문(30) 및 걸름망(40)과 인접한 하천 외곽에 각각 배치되어 해당 구성요소(작동수문 또는 걸름망)의 회동을 제어한다. 구체적으로, 제1, 제2 제어수단(35)(45)은 모터(미도시 됨) 및 이 모터에 의해 회전되는 권취드럼(미도시 됨)을 포함하는 구동부(350)(450)와, 상기 구동부(350)(450)의 권취드럼에 감기거나 풀리면서 상기 작동수문 또는 걸름망(40)의 회동을 단속하는 와이어(352)(452)를 포함하는 구성일 수 있다.The first and second control means 35 and 45 are respectively disposed in the outer stream adjacent to the operation gate 30 and the strainer 40 to control the rotation of a corresponding component (operating gate or strainer). Specifically, the first and second control means 35 and 45 may include a driving unit 350 and 450 including a motor (not shown) and a winding drum (not shown) rotated by the motor. It may be configured to include a wire 352, 452 to control the rotation of the operation gate or the strainer 40 while winding or unwinding the winding drum of the driving unit 350, 450.

좀 더 구체적으로, 상기 제1 제어수단(35)은 작동수문(30)의 자유단측 선회궤적의 접선방향 연장선상의 하천 외곽에 각각 배치되는 한 쌍의 구동부(350a,350b)와, 이 구동부들을 잇는 와이어(352)를 갖는다. 각각의 구동부(350a,350b)는 상기와 같이 모터와 이 모터에 의해 회전되는 권취드럼을 구비하며, 와이어(352)는 그 양단부가 상기 한쌍의 구동부(350a,350b) 권취드럼에 각각 권취되어 있으면서 그 중앙은 작동수문(30) 상측 선단과 연결되어 있다. 따라서 상기 한 쌍의 구동부(350a,350b)의 정·역회전에 따른 와이어 당김 또는 풀림 동작에 의해 상기 작동수문(30)은 소정의 작동범위내에서 회동되면서 수로를 전환시킨다.More specifically, the first control means 35 includes a pair of driving units 350a and 350b respectively disposed at the outside of the river on the tangential extension line of the free end side swing trajectory of the operation gate 30 and connecting the driving units. Has a wire 352. Each of the driving units 350a and 350b includes a motor and a winding drum rotated by the motor as described above, and the wire 352 has both ends thereof wound around the pair of driving units 350a and 350b winding drums, respectively. The center is connected to the upper end of the operation gate (30). Therefore, by the wire pulling or loosening operation of the pair of driving units 350a and 350b according to the forward and reverse rotation, the operation gate 30 is rotated within a predetermined operation range and changes the channel.

제2 제어수단(45)은 걸름망(40) 자유단측과 인접한 하천 외곽에 배치되는 하나의 구동부(450) 및 구동부(450)와 걸름망(40) 자유단측 상측 선단을 잇는 와이어(452)를 구비한다. 제2 제어수단(45)의 구동부(450)는 상기 제1 제어수단(35)의 구동부와 마찬가지로 모터(미도시 됨)와 이 모터에 의해 회전되는 권취드럼(미도시 됨)을 갖는다. 이러한 제2 제어수단(45)에 의해 회동이 제어되는 걸름망(40)의 경우 하천수의 흐름 방향으로 개방되는 구조이기 때문에 정·역회전되는 하나의 구동부와 그와 연계된 하나의 와이어만 가지고도 이에 대한 개방 또는 폐쇄를 제어할 수 있다. 따라서 상기한 제1 제어수단과는 달리 복수개의 구동부가 요구되지 않는다.The second control means 45 has one drive unit 450 and a wire 452 connecting the drive unit 450 and the free end side of the strainer 40 to the free end side of the stream adjacent to the free end side of the strainer 40. . The drive unit 450 of the second control means 45 has a motor (not shown) and a winding drum (not shown) rotated by the motor, similarly to the drive unit of the first control means 35. In the case of the filtering network 40 in which the rotation is controlled by the second control means 45, since the structure is opened in the flow direction of the river water, even if there is only one driving part that is forward and reverse rotation and one wire connected thereto, Can be controlled for opening or closing. Therefore, unlike the first control means described above, a plurality of driving units are not required.

상기한 구성으로 이루어진 본 발명의 작동 및 효과를 살펴보면 다음과 같다. Looking at the operation and effect of the present invention made of the above configuration are as follows.

도 3 내지 도 4는 본 발명에 따른 작동 상태도로서, 집중호우 등으로 인하여 하천이 불고 이와 함께 하천상에 쓰레기 부유물이 떠밀려오는 경우, 상기 하천상의 부유물 제거를 위해서는 작동수문(30)을 도 3과 같이 제어하여 기존 수로를 폐쇄하고 하천수가 보조수로(10)를 경유하도록 한다. 3 to 4 is an operating state diagram according to the present invention, when the stream is blown due to the heavy rain and the like and the waste floating on the river, the operation gate 30 to remove the floating on the river 3 As such, the existing waterway is closed and the river water flows through the auxiliary waterway 10.

이 때, 상기 작동수문(30)은 제1 제어수단(35)의 한 쌍의 구동부(350a,350b)에 의한 와이어(352)의 당김 동작에 의해서 중앙분리옹벽(20)에 회동가능하게 결합된 일측단부를 질점으로하여 회동되어 기존의 수로를 폐쇄하고 있으며, 걸름망(40)은 제2 제어수단(45)에 의해서 보조수로(10) 단부를 막고 있다. 이에 따라, 하천 상류측에 흘러내려온 하천수는 보조수로(10)를 경유하여 하천 하류측으로 흘러내려가게 되며, 이 과정에서 하천수에 포함된 부유물은 상기 걸름망(40)에 걸려지게 된다.At this time, the operation gate 30 is rotatably coupled to the central separation retaining wall 20 by a pulling operation of the wire 352 by the pair of driving units 350a and 350b of the first control unit 35. The one end is rotated as a vaginal point to close the existing channel, and the strainer 40 blocks the end of the auxiliary channel 10 by the second control means 45. Accordingly, the river water flowing down the stream upstream flows to the stream downstream side via the auxiliary channel 10, in this process the suspended matter contained in the river water is caught in the strainer (40).

한편, 하천 유량이 정상을 찾아 하천상에 부유물이 거의 없는 경우에는 도 4와 같이 작동수문(30)을 작동시켜 기존의 수로를 개방한다. 그리하면 상기 보조수로(10)가 폐쇄되어 이 보조수로(10) 측으로 하천수가 유입되지 않게 되고 하천의 물은 기존 수로를 따라 상류에서 하류로 원활히 흘러내려갈 수 있다. 이 경우에, 폐쇄되어진 보조수로(10) 측 걸름망(40)에 걸려진 부유물은 인력 또는 중장비 등을 이용하여 간단하게 걷어낼 수 있다.On the other hand, when the flow rate of the river finds the top and there is almost no float on the river, the operation water gate 30 is operated as shown in FIG. Thus, the auxiliary channel 10 is closed so that no river water flows into the auxiliary channel 10 and the water of the stream can flow smoothly from the upstream to the downstream along the existing channel. In this case, the suspended matter caught in the sieve network 40 on the side of the auxiliary channel 10 that is closed can be easily removed by using manpower or heavy equipment.

상기한 본 발명의 실시예에 따르면, 작동수문(30)의 회동에 따라 수로가 변경된다. 그 중, 보조수로(10)를 개방하는 형태로 수로가 변경되었을 경우에, 하천을 따라 흘러내려온 하천수는 보조수로(10)를 거치면서 걸름망(40)에 의해 그에 포함되어 있던 부유물이 걸러지게 된다. 즉, 본 발명은 장마철 하천이 급격히 불어나 하천 상에 부유물이 많아진 경우에 단순히 수로를 전환하는 것으로 하천수에 포함되어 있던 부유물을 효과적으로 걸러낼 수 있는 것이다.According to the embodiment of the present invention described above, the channel is changed in accordance with the rotation of the operation gate (30). Among them, when the channel is changed in the form of opening the auxiliary channel 10, the stream water flowing down the stream is filtered through the auxiliary channel 10 to filter the floating matter contained therein by the filter network 40. You lose. That is, the present invention can effectively filter out the floating matters contained in the river water by simply switching channels when the rainy season rivers are rapidly blowing up and the floating waters on the rivers increase.

이상에서 살펴본 본 발명인 소하천 부유물 처리시설에 의하면, 작동수문 제어에 따른 간단한 수로전환을 통해 하천 상에 포함된 부유물을 보조수로로 유도하여 간단하게 수거할 수 있다. 즉, 쓰레기의 수거에 소요되는 인력, 시간 및 비용을 최소화시킬 수 있는 동시에 수질오염을 효과적으로 방지할 수 있는 등의 이점이 있다.According to the small stream floating treatment facility of the present invention described above, it is possible to simply collect the suspended matter contained in the stream to the auxiliary water through the simple channel conversion according to the operation of the hydrological control. In other words, it is possible to minimize the manpower, time and cost required for the collection of waste, and at the same time can effectively prevent water pollution.

이상에서 설명한 것은 본 발명을 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, and the present invention is made without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in this field will have the technical spirit of the present invention to the extent that various modifications can be made.
