As a result, when the buoyancy body 7 is lowered, when the water level of rainwater flowing into the rainy season chamber 91 is increased, the buoyancy body 7 immediately detects it and closes the opening / closing plate 3, so that the rainy season soil 91 is no longer present. ) Rainwater can be prevented from flowing into the inside, and rainwater in the rainstorm chamber 91 can also be prevented from flowing backward to the opening and closing plate 3.

FIG. 6 is a perspective view illustrating a state in which a contaminant removing unit is installed in the sewer in FIG. 1, and FIG. 7 is a plan view and a side view of the contaminant removing unit extracted in FIG. 6.

As shown in Figures 6 and 7, the debris removal means is to prevent the inflow of debris into the opening and closing plate (3) by separating the various impurities before the sewage reaches the opening and closing plate (3) It is installed in multiple stages on the furnace 9.

In addition, the debris removal means can easily remove the debris with a tool such as a hook to improve the problems that the conventional screen network has a very easy after-care, do not interfere with the flow of sewage, small debris opening and closing plate It leads to (3) and can remove only big contaminants.

The first complex screen 8a has a structure in which both sides of the sewer are opened and the center portion is arranged in an inclined shape to the upstream side.

This form is to remove the contaminants contained in the rainwater primarily while cutting the water so as not to be disturbed the flow of rainwater flowing along the sewer (9).

" 형태로 배치되는 구조이다.And the second concave screen (8b) is disposed on the downstream side than the first concave screen, the central portion of the sewer (9) is inclined to the upstream side from both inner wall surface of the sewer to open.

"Is arranged in the form.

This structure disperses the contaminants into the first and second screens (8a) and the second (8b) screen to prevent the accumulation of contaminants on each of the screens (8a, 8b) to prevent dams from losing the ability to remove the contaminants For the purpose of the following, and also, the contaminants not removed by the first contaminant screen 8a can be removed through the second contaminant screen.

Each of the screens (8a, 8b) is provided with a plurality of support plate 81 is formed with a plurality of coupling holes 811 that can be fixed to the ground, and a plurality of predetermined intervals along the longitudinal direction of the support plate 81 It is configured to include a locking rod 82 having a slope in the advancing direction of the sewage.

At this time, at least two or more of the catching rods 82 of the first catch screen 8a and the second catch screen 8b are integrally connected to the end of the catching rod 82 and supported on the ground. The structure is installed symmetrically and installed on the sewer 9 more stably.

Here, the support plate 81 is a structure that can be firmly fixed to the ground of the sewer by the fixing means such as anchor bolt to the coupling hole 811.

And each of the engaging rods 82 is installed at intervals of 3cm to 10cm to fulfill the function of filtering the contaminants without disturbing the flow of sewage.

This means that when the distance between each locking rod 82 is less than 3 cm, the trap is caught in the width direction of each of the locking rods 82, the flow of sewage is hindered, and eventually the trappings to be filtered as the time passes, the locking rod 82 This is because it is just passed to the upper part of the seizure because the dam phenomenon occurs over the entirety of the catching rod 82, and the sewage level is eventually higher than the height of the catching rod 82.

In addition, when the interval between each of the engaging rods 82 is 10 cm or more, since the function of filtering the debris is reduced, it is not preferable.

In addition, the locking rods 82 are inclined at an angle of 30 degrees to 60 degrees.

This is not preferable because the height of the sewage bar 82 is too low when the internal angle of the catching rod 82 is 30 ° or less, so that impurities are not easily caught when the level of sewage is high. It is not desirable because the contaminants caught in 82 are entangled, impeding the flow of water and dams forming and losing their function.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include many such variations.
