본 발명의 내부필터와 외부필터는 철사, 스텐리스사 등 금속사를 사용한 것이며, 하부가 개방된 캡(cap) 모양으로 형성되며, 이 범주에서 구체적인 모양은 다양하게 형성될 수 있다.The inner filter and the outer filter of the present invention are made of metal yarn such as wire or stainless steel, and are formed in a cap shape having an opened bottom. Various shapes can be formed in this category.

내부필터(110)의 캡형으로 형성되고 하부 개방부의 크기는 배수구의 크기보다 더 크게 형성되며, 바람직하게는 1.5배 이상 크게 형성하여 배수구를 덥어 설치하게 되며, 개방부 가장자리를 따라 금속재 철사의 끝이 뾰족하게 돌출되도록 형성되어 바닥에 닿은 상태에서 빗물이 배수되는 과정에 유동이 없이 제자리를 유지할 수 있게 된다.The size of the lower opening portion is formed to be larger than the size of the drain hole, preferably 1.5 times or more, so that the drain hole is installed, and the end of the metal wire along the edge of the opening portion So that the rainwater is drained in a state in which the rainwater is in contact with the floor.

내부필터의 망목(구멍) 크기는 외부필터 망목보다 작고, 외부필터의 망목 크기는 내부필터 망목보다 4배 이상 크기로 형성되어 비닐, 낙엽 등의 큰 사이즈의 이물질을 걸러주게 되며, 외부필터의 측면망을 비스듬하게 경사지게 형성하게 되면 빗물에 의해 걸린 이물질이 측면망을 타고 올라가 상부망에 모이도록 형성할 수 있다.The mesh size of the inner filter is smaller than that of the outer filter mesh, and the size of the mesh of the outer filter is formed to be four times or more larger than that of the inner filter mesh, thereby filtering large sized foreign materials such as vinyl and leaves. If the net is formed obliquely, the foreign matter caught by the rainwater can be formed so as to ride on the side net and gather in the upper net.

또한 외부필터를 내부필터를 씌웠을 때 두 필터는 소정 간격 이격되며, 그 간격은 5-10cm 정도가 바람직하다.Also, when the external filter is covered with the internal filter, the two filters are spaced apart from each other by a predetermined distance, and the interval is preferably about 5-10 cm.

내부필터(110)는 상부망(117)은 평평하고, 측면망(118)은 들어가고 나가고 하는 꺽임부(114,115)가 다수 형성되어 측면망 넓이를 크게 함으로써 빗물에 포함된 이물질이 빗물과 함께 원활하게 망목을 통하여 배수될 수 있도록 할 수 있다.The internal filter 110 has a plurality of folded portions 114 and 115 formed by flattening the upper net 117 and entering and leaving the side net 118 to enlarge the side net width so that the foreign matter contained in the rainwater flows smoothly So that it can be drained through the mesh.

내부필터(110)는 망목이 가로선과 세로선을 짜서 사각 모양의 망목으로 형성하고, 외부필터(120)는 측면망(128)을 세로선(121)만으로 형성하여 긴 틈새로 작은 이물질들은 원활하게 통과하여 배수될 수 있도록 하면서, 낙엽이나 비닐들과 같은 큰 이물질은 걸려서 상부망으로 올라가 모이도록 형성할 수 있다.The inner filter 110 is formed by a rectangular mesh of a mesh with a horizontal line and a vertical line and the outer filter 120 is formed by only the vertical line 121 of the side net 128 so that small foreign substances smoothly pass through the long gap Large debris, such as leaves or vinyls, can be hooked up and assembled to the top net, while allowing it to drain.

내부필터와 외부필터의 모양은 원형캡, 사각캡, 다각형 캡 등 다양한 모양으로 형성할 수 있고, 상부망과 측면망의 망목 모양과 크기를 달리 형성할 수 있다.The shape of the inner filter and the outer filter can be formed into various shapes such as a circular cap, a square cap, and a polygonal cap, and the shape and size of the mesh of the upper net and the side net can be formed differently.

본 발명은 망목이 보다 작고 개방부 크기가 배수구보다 더 큰 내부필터(110)를 빗물 배수구에 설치하고, 내부필터(110) 망목보다 4배이상 큰 망목의 외부필터(120)를 캡(cap)형으로 형성하여 내부필터를 씌운 다음, 결합핀으로 고정하여 설치함으로써 낙엽, 비닐 등의 비교적 큰 이물질을 외부필터로 일차 걸러냄으로써 내부필터가 막히지 않고 원활하게 빗물이 배수로 빠지도록 하는 효과가 있다.In the present invention, an internal filter 110 having a smaller mesh size and an opening size larger than a drain hole is installed in a rainwater drain port, and a mesh external filter 120, which is four times larger than the internal filter 110 mesh, The inner filter is covered with the inner filter, and then the outer filter is fixed by the coupling pin. Thus, relatively large foreign matters such as fallen leaves and vinyl are firstly filtered by the external filter, so that the internal filter is not clogged and the rainwater is smoothly drained.

또한 본 발명은 외부필터(120)의 측면망이 내부필터(110)의 측면망으로부터 소정간격 이격되는 큰 사이즈로 형성함으로써 낙엽이나 비닐 등이 걸린 상태에서도 물이 원활하게 내부필터(120)으로 흘러가는 효과가 있으며, 또한 측면망(128)을 비스듬하게 형성하여 걸린 낙엽이나 비닐 등이 측면망(128)을 따라 위로 유동하게 하여 상부에 모이도록 형성함으로써 물이 배수구로 더욱 원활하게 흘러갈 수 있도록 하는 효과가 있다.In addition, since the side net of the external filter 120 is formed in a large size spaced apart from the side net of the internal filter 110 by a predetermined distance, the water smoothly flows into the internal filter 120 And the side net 128 is formed obliquely so that the fallen leaves or the vinyl or the like that are caught and flowed along the side net 128 are gathered at the upper part so that the water flows more smoothly into the drain .

도 4,5의 외부필터(120)는 평평한 상부망(128)과 상부망에서 길게 경사지게 형성된 세로선(121)들로 이루어진 측면망(128)로 이루어진 것이다. The outer filter 120 shown in FIGS. 4 and 5 includes a flat upper network 128 and a side net 128 formed of vertical lines 121 formed at an upper slant in the upper network.

외부필터(120)의 경지지고 U자형의 세로선(121) 모양은 하부 바닥면과 접촉부분에서 틈새가 커져 빗물과 비교적 작은 이물질이 쉽게 통과할 수 있도록 하면서, 측면망(128)에 걸린 낙엽이나 비닐 등은 빗물이 밀려와 모이면서 위로 이동하여 평평한 상부망(127)에 모이게 되며, 이로 인하여 측면망(128)로 빗물흐름은 더욱 원활하게 된다.The vertical filter 121 has a shape of a long vertical U-shaped vertical line 121, which allows clearance between rainwater and relatively small foreign objects to be easily passed through at the contact portion with the lower floor, The rainwater is pushed and gathered, and the rainwater flows upward and collects in the flat upper net 127, thereby making the rainwater flow more smoothly to the side net 128.

도 6은 옥상 배수관에 설치된 도 4,5의 여과장치으로, 외부필터(120)에 의해 내부필터(110)와 소정간격 외곽에서 비닐, 낙엽 등을 걸러주고 빗물은 원활하게 큰 외곽둘레를 가진 외부필터를 통과하여 흐르게 되고, 내부필터 또한 다수 꺽임부를 형성하여 넓은 측면망을 통하여 원활하게 배수되도록 형성된 것이다.6 is a filter device of FIGS. 4 and 5 installed on a roof drainage pipe. The external filter 120 filters out vinyls, fallen leaves and the like at a predetermined interval from the internal filter 110 and the rainwater flows smoothly outward And the inner filter is formed so as to have a plurality of bent portions and to be smoothly drained through the wide side net.

외부필터(120)와 내부필터(110)를 결합하도록 형성된 결합핀(130);으로 형성된 것을 특징으로 하는 빗물 배수구의 이중필터.An upper net 127 formed to be flat by crossing a vertical line 111 and a horizontal line 112 made of a metal and a vertical line formed at predetermined intervals along the edge of the upper net 127 and curved convexly downward and outward 121 are formed on the outer surface of the inner filter 110. The opening portion opened downward is formed to be larger than the inner filter 110 to be spaced apart from the outer surface of the inner filter 110 when the inner filter 110 is covered, An external filter (not shown) is formed to filter the relatively large foreign matter into the side net 128 formed by the vertical line 121 and to move the foreign matter upward along the vertical line by the flow of the rainwater to be collected in the flat upper net 127 120;

The upper net 117 is formed by a top net 117 and a side net 118 crossing a vertical line 111 and a horizontal line 112 made of a metal and the upper net 117 is formed flat. The side net 118 formed by turning at right angles to the direction is formed with a plurality of folded portions 115 entering into the inside and folded portions 114 coming out to the outside and opening portions opened downward are formed to be 1.5 times larger than the drain port, An inner filter 110 formed to cover the side net 118 at a predetermined distance from the outer periphery of the drain port and to filter a relatively small foreign matter having passed through the external filter;

And a coupling pin (130) formed to join the external filter (120) and the internal filter (110). 삭제delete 삭제delete 삭제delete
