It is possible to deform in shape, and the support 8 having the guide roller 7 can correspond to the appropriate number and shape according to the shape of the guide rail 6.

또한 도면부호 10은 상기 가이드 레일(6)을 상기 취수탑(5') 벽면 소정부위에 고정 지지시키기 위한 지지체이고, 도면부호 11은 상기 부유물 네트(2)를 현가키위한 경질의 와이어이며, 도면부호 12는 상기 가이드 로울러(7)을 상기 지지체(8)에 축착시키기 위한 브래킷이고, 도면부호 13은 상기 지지체(8)의 착탈을 원활하게 하기 위한 스페이서(spacer)이며, 도면부호 14는 상기 지지체(8)를 상기 작업 데크(4)에 고정시키기 위한 고정편이고, 도면부호 15는 스크리인, 도면부호 16은 수면, 도면부호 17은 키 플레이트이다.In addition, reference numeral 10 is a support for fixing and supporting the guide rail 6 to a predetermined portion of the wall of the water intake tower 5 ', and reference numeral 11 is a hard wire for suspending the float net 2, 12 denotes a bracket for fastening the guide roller 7 to the support 8, reference numeral 13 denotes a spacer for smoothly attaching and detaching the support 8, and reference numeral 14 denotes the support ( 8) is a fixing piece for fixing the work deck 4, 15 is a screen, 16 is water and 17 is a key plate.

이와 같은 종래 발명은 그 부피가 크므로 먼저 취수구(5) 전방 양측의 취수탑(5') 벽면 소정부위에 수직으로 가이드 레일(6)을 고정시킨 후, 작업 데크(4)를 수면에 띄운 상태(댐등의 집수가 이루어지지 않은 상태에서는 가이드 레일(6) 하부에 고정된 미도시 설치대위에 올려 놓은 상태)에서 상기 작업 데크(4)가 상기 가이드 레일(6)을 따라 상하로 이동될 수 있도록 상기 가이드 레일(6)과 대응되는 가이드 로울러(7)를 가진 1단 또는 2단의 지지체(8)를 상기 작업 데크(4) 상면의 후방 양측 소정부위에 고정시키게 되는데 우선 상기 작업 데크(4) 상면의 후방 양측 소정부위에 형성된 리브(4',4") 사이로 상기 지지체(8)를 거치시킨 후 상기 리브(4',4") 및 상기 지지체(8)에 각각 형성된 삽입구멍안(4a',4a",8a)으로 고정핀(14)을 끼운 다음 키 플레이트(17로 고정시키고, 상기 리브(4',4") 및 상기 지지체(8)간에 형성된 틈새로 스페이서(13)를 끼운 다음 나사고정시키게 되면 설치작업이 완료된다.Since the conventional invention has such a large volume, the guide rails 6 are fixed to a predetermined portion of the wall of the intake tower 5 'on both sides in front of the intake port 5, and then the work deck 4 is floated on the water surface. In a state where the dam is not collected, the work deck 4 can be moved up and down along the guide rail 6 in a state where it is placed on a mounting stand not shown fixed to the lower part of the guide rail 6. One or two stage support bodies 8 having guide rollers 7 and corresponding guide rollers 7 are fixed to predetermined positions on both sides of the upper surface of the work deck 4. The support body 8 is mounted between the ribs 4 'and 4 "formed at predetermined portions on both sides of the rear side of the back, and then inserted into the insertion holes 4a' formed in the ribs 4 'and 4 " Insert the retaining pins 14 into 4a ", 8a) and then fix them with the key plate 17, When the rib (4 ', 4 ") and inserted into the gap spacer 13 formed between the supporting member (8) thereby, and then screwing the installation process is completed.

작업 데크(4)에 가이드 로울러용 지지체(8)를 1단 또는 2단으로 설치함에 있어 상술한 바와 같은 착탈수단의 용접 등에 의한 방법으로 일체화시킬 수도 있다.In installing the support roller support body 8 for a guide roller in the 1st stage or 2nd stage, it can also be integrated by the method of welding of the detachable means as mentioned above.

한편, 작업 데크(4)가 유속에 의한 하중, 풍압 및 파도 등에 따른 여러 방향에서의 하중조건을 견디면서 원활하게 상하이동 될 수 있기 위해서는 가이드 레일(6)과 가이드 로울러(7)간의 마찰을 최소한으로 줄일 필요가 있게 되는데 이를 위해 제 4 도에 도시한 바와 같이 상기 가이드 레일(6)과 가이드 로울러(7)간에 소정 폭만큼의 간격(d)을 두었으며, 또한 상기 가이드 로울러(7)의 모서리면에 소정 규격만큼의 라운딩(R)을 하였다.On the other hand, in order for the work deck 4 to be smoothly moved while being able to withstand the load conditions in various directions due to the load due to the flow velocity, the wind pressure, and the wave, the friction between the guide rail 6 and the guide roller 7 is minimized. To this end, as shown in FIG. 4, a distance d of a predetermined width is provided between the guide rail 6 and the guide roller 7, and the edge of the guide roller 7 is also provided. The surface was rounded (R) by a predetermined standard.

이와 같이 된 종래 발명은 작업 데크(4)가 수면(16)으로부터 소정 깊이만큼 잠긴 상태에서 별도의 구동장치 없이도 수시로 변화되는 수위에 따라 적절히 상하이동을 하면서 부유물의 취수구(5)로의 유입을 막게 됨으로써 용수의 처리비용 절감 및 각종 설비의 보호에도 만전을 기할 수 있게 되는 등의 장점이 있다.In the conventional invention as described above, the work deck 4 is locked by a predetermined depth from the water surface 16 to prevent inflow of the floating water inlet 5 while appropriately moving in accordance with the level of water, which changes frequently from time to time without a separate driving device. There are advantages such as reducing the treatment cost of water and ensuring the protection of various facilities.

그러나 이러한 종래의 기술에서 가이드 로울러가 가이드 레일을 상하로 이동함에 있어서, 지지체에 설치된 가이드 로울러가 파손되거나 지지체로부터 떨어져 나가면 가이드 레일로부터 가이드 조립체가 분리되어 부유물방지장치 전체가 파손되거나 분리된 부유물 방지장치가 취수탑등에 충돌하여 사고의 위험이 크게 될 수가 있었다.However, in this conventional technology, when the guide roller moves the guide rail up and down, when the guide roller installed on the support is broken or is separated from the support, the guide assembly is separated from the guide rail, and the entire float prevention device is broken or separated. The collision with water intake towers could increase the risk of accidents.

따라서 가이드 로울러가 지지체에 분리되지 않는다하더라도 외력에 의하여 가이드 로울러 양측에 대응하고 있는 지지체가 벌어지는 경우에도 상기와 같이 가이드로울러로부터 가이드 조립체가 분리될 위험이 있다는 문제점이 있었다.Therefore, even if the guide roller is not separated from the support, there is a problem that the guide assembly may be separated from the guide roller even when the supports corresponding to both sides of the guide roller are opened by the external force.

본 발명은 상기와 같이 종래 발명의 문제점을 해결하기 위한 것으로서, 내측 상면상에 소정 간격으로 다수개의 부력체가 고정되고, 외측 둘레에는 부유물 네트(2)가 둘러 싸여지며, 상면 테두리 부위에는 작업용 난간(3)이 설치되어진 작업 데크(4)가 취수구 전방 양측의 소정부위에 수직으로 고정된 가이드레일(6)을 따라 상하로 이동될 수 있도록 상기 작업데크의 상면 후방양측 소정부위에 지지체(8)가 고정된 것에 있어서, 상기 가이드레일의 수직방향으로 형성된 가이드홈과; 상기 가이드홈에 치합되도록 상기 지지체의 말단에 가이드돌기가 형성되는 것을 그 구성상의 특징으로 한다.The present invention is to solve the problems of the conventional invention as described above, a plurality of buoyancy body is fixed at a predetermined interval on the inner upper surface, the floating net (2) is wrapped around the outer circumference, the work railing ( The support 8 is provided on the upper and rear predetermined portions of the upper surface of the work deck so that the work deck 4 on which the 3) is installed can be moved up and down along the guide rail 6 fixed perpendicularly to the predetermined portions on both sides of the water inlet front is vertically fixed. In the fixed, the guide groove formed in the vertical direction of the guide rail; It is characterized in that the guide protrusion is formed on the end of the support to be engaged with the guide groove.

이러한 본 발명은 가이드 레일의 가이드홈에 치합되는 가이드 돌기가 지지체의 일부로서 구성되어 지지체와 상기 가이드 레일이 분리될 위험이 전혀 없다.The present invention has no risk of separating the support from the guide rail is configured as a guide protrusion which is engaged with the guide groove of the guide rail as part of the support.
