Description

환경친화형 리프트식 어도{Environment-friendly lifting fishway}Environment-friendly lifting fishway {Environment-friendly lifting fishway}

본 발명은 강이나 하천 등 낙차가 큰 부위의 수공구조물에 설치되어 물고기의 이동에 인위적으로 도움을 줄 수 있도록 한 리프트식 어도에 관한 것으로, 특히 리프팅수조에 의한 어류의 압사를 방지할 수 있도록 한 환경친화형 리프트식 어도에 관한 것이다.The present invention relates to a lift type fishery that is installed in a hand structure of a large drop of water such as a river or a river to artificially assist the movement of fish, and in particular, to prevent the seizure of fish by a lifting tank. It relates to an environmentally friendly lift fishery.

일반적으로 댐이나 취입보를 포함한 하천횡단 수공구조물들은 하천에 서식하는 회유성 어류는 물론 계절에 따라 국지회유하는 어류 및 수생동물들의 이동통로를 막는다. 이는 수공구조물 상류의 하천 어류 개체수를 급속하게 감소시키거나 하천 생태계의 다양성 및 균형에 심각한 영향을 초래할 수 있다. In general, river cross-handed structures, including dams and blowholes, prevent the flow paths of fishes and aquatic animals in local seasons, as well as sedimentary fish that live in rivers. This can rapidly reduce the number of river fish populations upstream of the hand structure or cause serious impacts on the diversity and balance of river ecosystems.

이러한 영향을 최소화하기 위한 방편으로 어도가 개발되었으며, 어도는 하천에서 어류 이동에 장애물이 있을 경우 어류의 원활한 이동을 유도하는 인공수리시설물이다. 과거에는 경제적인 어족자원 보호에 중점을 두었으나 최근에는 전체적인 어류 및 수생생물의 이동을 가능케 하여 생태계의 다양성 및 건전성을 도모하기 위한 목적으로 어도의 인식이 전환되고 있는 추세이다.To minimize these effects, fisheries have been developed, which are artificial repair facilities that induce smooth movement of fish when there are obstacles to fish movement in rivers. In the past, the focus was on protecting fish stocks economically, but in recent years, the perception of fish stocks has been shifting to promote the diversity and soundness of ecosystems by enabling the movement of fish and aquatic organisms.

이와 같은 어도는 풀(pool)식 어도, 수로식 어도, 운영조작식 어도, 혼용식 어도 등 많은 종류의 어도가 개발되어 사용되고 있다. 이 중에서 특히 종래 운영조작식 어도의 한 종류인 종래 리프트식 어도는 첨부도면 도1에 도시된 바와 같이 호이스트체인(11)에 의해 승강되는 리프팅수조(10)가 이동할 수 있는 승강통로(12)가 수공구조물(13)의 하류측에 설치되어 있었으며, 수공구조물(13)의 하류측에는 상류측으로부터 이어진 수로관(14)이 승강통로(12) 하부에 형성된 개구부(12a)를 통해 하류측을 향해 약한 수압으로 방류하도록 되어 어류가 물이 흐르는 방향에 대해 역행하려는 성질을 이용 하류측의 어류를 개구부(12a) 안쪽으로 유인할 수 있도록 되어 있었고, 그 개구부(12a) 아래쪽에는 리프팅수조(10)가 잠길 수 있는 수조수용실(15)이 형성되어 있었다.Such fishes have been developed and used in many types of fish, such as pool fishes, waterways fishes, operating fishes, and mixed fishes. Among them, a conventional lift type fish which is a kind of conventional operation type fish type has a lifting passage 12 through which the lifting tank 10 lifted by the hoist chain 11 can move as shown in FIG. 1. It was provided on the downstream side of the hand structure 13, and on the downstream side of the hand structure 13, a water pipe 14 extending from the upstream side has a weak hydraulic pressure toward the downstream side through an opening 12a formed in the lower part of the lifting passage 12. It was designed to discharge the fish to the downstream side to the inside of the opening 12a by using the property of the fish to reverse the direction of water flow, and the lifting tank 10 can be locked under the opening 12a. The tank accommodating chamber 15 which was present was formed.

즉, 리프팅수조(10)가 상승될 때 개구부(12a)에 머물던 어류가 리프팅수조(10)에 포획되어 상승된 후 리프팅수조(10)의 전방측에 설치된 방출도어(16)를 통해 상류측으로 방류되도록 되어 있었다.That is, the fish that stayed in the opening 12a when the lifting tank 10 is raised is captured by the lifting tank 10 and raised, and then discharged to the upstream side through the discharge door 16 installed at the front side of the lifting tank 10. I was supposed to.

그러나, 이와 같은 종래 리프트식 어도는 리프팅수조(10)가 하강되면서 수조수용실(15)에 진입될 때 수조수용실(15)에 머물던 어류가 미처 수조수용실(15)을 빠져나가지 못하는 경우 리프팅수조(10)에 밑에 깔리면서 압사되거나 손상되는 문제점이 있었다.However, such a conventional lift type fish is lifted when the fish staying in the tank storage room 15 when the lifting tank 10 is lowered and enters the tank storage room 15 does not exit the tank storage room 15. There was a problem of being sanded or damaged while being laid under the water tank (10).

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 수조수용실로 진입되는 리프팅수조에 의한 어류의 압사를 예방할 수 있는 환경친화형 리프트식 어도를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an environmentally friendly lift type fish can prevent the pressure of the fish by the lifting tank entering the tank chamber.

이러한 본 발명의 목적을 달성하기 위하여 수조수용실의 바닥면에 어류도피공간을 형성하고, 어류도피공간으로부터 리프팅수조의 내부로 통하는 대피구를 리프팅수조의 바닥면에 형성하며, 리프팅수조의 내부를 가로방향으로 가로지르는 힌지축에 설치된 힌지암에 대피구를 개폐하기 위한 플립도어를 설치하고, 힌지축의 일측단부를 리프팅수조의 외부로 노출시켜 그 끝 부분에 도어릴리즈암을 설치하며, 수조수용실의 측벽에 도어릴리즈암의 단부에 걸리는 도그를 설치하고, 리프팅수조의 측벽과 수조수용실의 벽면에 서로 만나면서 리프팅수조의 하강높이를 제한하는 가동스토퍼와 고정스토퍼를 각각 설치하여 환경친화형 리프트식 어도가 제공된다.In order to achieve the object of the present invention to form a fish evacuation space on the bottom surface of the tank accommodation chamber, the evacuation port leading from the fish escape space to the interior of the lifting tank to the bottom surface of the lifting tank, the inside of the lifting tank A flip door for opening and closing the evacuation opening is installed on the hinge arm installed on the hinge shaft crossing in the horizontal direction, and one side end of the hinge shaft is exposed to the outside of the lifting tank, and a door release arm is installed at the end thereof. An eco-friendly lift type is provided by installing a dog that is applied to an end of the door release arm on the side wall of the lifting tank, and installing a movable stopper and a fixed stopper that meet each other on the side wall of the lifting tank and the wall surface of the tank storage chamber to limit the height of the lifting tank. Adobe is provided.

이상에서 설명한 바와 같은 본 발명은 리프팅수조가 수조수용실로 진입할 때 미처 수조수용실 밖으로 대피하지 못한 어류가 피할 수 있는 어류도피공간이 수조수용실 바닥에 마련되어 있기 때문에 리프팅수조에 의한 어류의 압사를 예방할 수 있는 효과가 있으며, 더욱이 리프팅수조가 수조수용실에 진입될 때 개방되는 플립도어가 리프팅수조에 설치되어 있으므로, 어류도피공간에 잔류하던 어류가 리프팅수조 내부로 진입할 수 있는 효과도 있다.As described above, in the present invention, when the lifting tank enters the tank accommodation chamber, the fish evacuation space that can be avoided by evacuating fish out of the tank accommodation chamber is provided at the bottom of the tank accommodation chamber, so There is an effect that can be prevented, and furthermore, since the flip door, which is opened when the lifting tank enters the tank accommodation chamber, is installed in the lifting tank, the fish remaining in the fish escape space can enter the lifting tank.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도10에 도시된 바와 같이 리프팅수조(30)가 상승위치에서 하강되어 수조수용실(50)로 진입되면, 리프팅수조(30)의 외측벽면에 설치되어 있는 가동스토퍼(67)가 수조수용실(50)의 내측벽면에 설치되어 있는 고정스토퍼(57)에 걸리면서 하강높이가 제한된다.As shown in Figs. 2 to 10, when the lifting tank 30 descends from the rising position and enters the tank accommodation chamber 50, the movable stopper 67 is installed on the outer wall surface of the lifting tank 30. The falling height is limited while being caught by the fixed stopper 57 provided on the inner wall surface of the tank accommodation chamber 50.

이때 리프팅수조(30)와 수조수용실(50)의 바닥면 사이에 어류도피공간(52)이 형성되어 있기 때문에 리프팅수조(30)가 수조수용실(50)로 진입하기 전에 수조수용실(50)을 미처 빠져나가지 못한 어류가 어류도피공간(52)에서 안전하게 머물게 된다.At this time, since the fish evacuation space 52 is formed between the lifting tank 30 and the bottom surface of the tank accommodation chamber 50, the tank 30 before the lifting tank 30 enters the tank accommodation chamber 50. The fish that have not escaped) stay safely in the fish escape space 52.

또한, 리프팅수조(30)가 수조수용실(50)로 진입될 때 리프팅수조(30)의 외측으로 돌출된 힌지축(62)의 단부에 설치되어 있는 도어릴리즈암(65)이 수조수용실(50)의 내측벽면에 설치되어 있는 도그(55)에 접촉되면서 플립도어(60)가 개방된다.In addition, the door release arm 65 is provided at the end of the hinge shaft 62 protruding out of the lifting tank 30 when the lifting tank 30 enters the tank accommodation chamber 50. The flip door 60 is opened while contacting the dog 55 provided on the inner wall surface of the 50.

즉, 리프팅수조(30)가 하강될 때 도어릴리즈암(65)은 고정된 도그(55)에 의해 밀려서 상승되는 방향으로 회전되며, 이와 동시에 도어릴리즈암(65)에 연결되어 있는 힌지축(62)과 힌지암(63)(64) 및 플립도어(60)가 모두 함께 힌지축(62)을 기점으로 상승방향으로 회동되면서 리프팅수조(30)의 바닥면에 형성되어 있는 대피구(40)가 개방되어 어류도피공간(52)에 머물던 어류가 리프팅수조(30)의 내부로 진입할 수 있게 된다.That is, when the lifting tank 30 is lowered, the door release arm 65 is rotated in a rising direction by being pushed by the fixed dog 55 and at the same time the hinge shaft 62 connected to the door release arm 65. ) And the hinge arm (63) (64) and the flip door (60) are all rotated in the upward direction from the hinge axis (62) as the evacuation hole (40) formed on the bottom surface of the lifting tank (30) The fish that has been opened and stayed in the fish evacuation space 52 can enter the inside of the lifting tank 30.

한편, 호이스트체인(20)에 의해 리프팅수조(30)가 상승되면, 도그(55)에 걸려 있던 도어릴리즈암(65)이 아래쪽으로 회동되면서 동시에 도어릴리즈암(65)에 연결되어 있던 힌지축(62)과 힌지암(63)(64) 및 플립도어(60)가 아래쪽으로 회동되어 대피구(40)가 폐쇄된다.On the other hand, when the lifting tank 30 is lifted by the hoist chain 20, the door release arm 65 hanging on the dog 55 is rotated downward, and at the same time the hinge shaft (which is connected to the door release arm 65) 62, the hinge arms 63, 64 and the flip door 60 are rotated downward to close the sheath 40.

즉, 플립도어(60)의 자중에 의해 무게중심이 힌지축(62)을 기준으로 플립도어(60)에 매우 가깝게 편중되어 있기 때문에 플립도어(60)을 닫기 위한 별다른 동력의 도움 없어도 플립도어(60)는 자중에 의해 스스로 닫히게 된다.That is, since the center of gravity of the flip door 60 is biased very close to the flip door 60 on the basis of the hinge axis 62, the flip door 60 may be flipped without the help of any other power for closing the flip door 60. 60) is closed by itself.

이후 리프팅수조(30)가 승강통로(23)를 따라 상승되면, 리프팅수조(30)의 외측벽면에 설치되어 있던 롤러(21)가 승강통로(23)의 내측벽면에 설치되어 있는 가이드레일(22)을 따라 구르면서 리프팅수조(30)가 일정한 궤적으로 안내되면서 상승된다.Then, when the lifting tank 30 is elevated along the lifting passage 23, the roller 21, which is provided on the outer wall surface of the lifting tank 30, is installed on the inner wall surface of the lifting passage 23. While lifting along the lifting tank 30 is guided to a constant trajectory is raised.

첨부도면 도10에 도시된 바와 같이 리프팅수조(30)가 최상단위치에 도달되면, 리프팅수조(30)의 멈추게 되며, 곧이어 도어개폐실린더(38)의 피스톤로드(39)가 수축되면, 행거암(36)(37)이 피스톤로드(39)에 의해 회동되면서 방출도어(35)가 개방되어 어류방출구(34)가 열리게 되며, 리프팅수조(30)에 실려 있던 어류가 물과 함께 상류측으로 방출되어 어류의 인위적인 소상이 가능하게 되며, 얼마 후 방출도어(35)는 다시 닫히게 되고, 호이스트체인(20)에 의해 리프팅수조(30)는 하강과 상승을 반복하게 된다.As shown in FIG. 10, when the lifting tank 30 reaches the uppermost position, the lifting tank 30 stops, and when the piston rod 39 of the door opening / closing cylinder 38 is contracted, the hanger arm ( 36) 37 is rotated by the piston rod 39, the discharge door 35 is opened to open the fish discharge port 34, the fish carried in the lifting tank 30 is discharged upstream with water The artificial small phase of the fish is possible, and after a while, the discharge door 35 is closed again, and the lifting tank 30 is repeatedly lowered and raised by the hoist chain 20.
