As shown in Figures 1 to 5, the present invention is to open and close the sewage inlet 72 while rotating in the front and rear direction by the buoyancy body 40 is raised and lowered in accordance with the inflow amount of rainwater flowing into the rainwater soil chamber (70) The sewage inlet 72 can be opened and closed quickly through the arc opening and closing plate 30 to prevent the earth and sand from flowing into the rainwater discharge chamber with rainwater, and the rainfall amount after the arc opening and closing plate 30 is closed. As the water pressure decreases due to the decrease, when the arc open / close board 30 is opened, the response speed of the arc open / close board 30 is increased very quickly by using a permanent magnet to prevent sewage from entering the stream, thereby preventing the stream from being contaminated. It relates to rainwater and earth and sand inflow prevention device having an arc-shaped opening and closing plate to.

Rainwater and earth and sand inlet prevention device having such an arc opening and closing plate is largely composed of five parts, which is the frame 10, the cover plate 13, respectively, which is addressed to the frame 10, the rotating shaft 20, It consists of a single structure composed of the buoyancy body 40 and the arc-shaped opening and closing plate 30.

The frame 10 is a structure installed in the sewage inlet hole 71 exposed on the sewer 80.

The frame 10 has a sewage discharge side relatively close to the other end of the arc opening and closing plate 30 in response to the rotation radius of the arc opening and closing plate 30 when the arc opening and closing plate 30 is closed. It is a structure that is installed lower.

At this time, the frame 10 is the sewage discharge side is the sewage inlet side through the two connecting frame 11 which is vertically coupled to the other end and the horizontal frame 12 is coupled to both ends of each of the connecting frame 11 It is a structure installed relatively lower.

This structure is formed by the arc-shaped opening and closing plate 30 is curved in an "arc" shape, the other side of the arc-shaped opening and closing plate 30 is rotated when the arc-opening and closing plate 30 is rotated to the rear by the rotation of the rotating shaft (20). This is to allow the sewage inlet 72 to be closed in response to the position of the arc-shaped opening and closing plate 30 because the height is lower than one side.

In addition, the horizontal frame 12 may be configured as a round rod so that foreign matter such as stones or gravel is not seated. This is to prevent the complete closure due to foreign matter such as stones or gravel when the arc-shaped opening and closing plate 30 is closed.

In addition, the cover plate 13 is a structure that is coupled to the upper surface of one side of the frame 10 so that the sewage inlet 72 is formed on the other side of the frame (10).

The bottom surface of the cover plate 13 is a structure that is further coupled to the stopper plate 131 to control the opening of the arc-shaped opening and closing plate 30 to rotate forward by its own weight.

Here, since the arc-shaped opening and closing plate 30 is biased forward, the drainage inlet 72 is opened because the center of gravity of the arc-opening plate 30 is always positioned on the bottom surface of the cover plate 13 so as to overlap the cover plate 13. Keep it intact.

At this time, the stopper plate 131 serves to prevent the arc-shaped opening and closing plate 30 from being excessively rotated forward by the biased center of gravity. This is because the weight of the buoyancy body 40, which will be described later than the arc-shaped opening and closing plate 30 is heavier, to prevent the arc-shaped opening and closing plate 30 is stored in the superior soil chamber 70 to lose its function.

The rotating shaft 20 is rotatably coupled through first connecting means 21 which is vertically coupled to both bottom surfaces of the frame 10 (shown in FIG. 3I).

Here, the first connecting means 21 includes two first supporting rods 211 vertically coupled to both bottom surfaces of the frame 10, and brackets 212 coupled to ends of the respective first supporting rods 211. And, the rotating shaft 20 is configured to include a bearing (B) fixed to the upper surface of each bracket 212 in a coupled state.

The first connecting means 21 is for installing the rotating shaft 20 in the rainwater soil chamber 70 through the first support rod 211, and the bracket 212 is coupled to the end of the first support rod 211. However, the bracket 212 is configured to extend inwardly of the frame 10, and is a structure in which a bearing (B) coupled to the rotating shaft 20 to the upper surface of the extension portion of the bracket 212 is fixed.

In addition, the buoyancy body 40 is moved up and down in accordance with the level of the initial excellent water flowing into the rainwater chamber 70 through the second connecting means 41 coupled to the center of the rotary shaft 20 to rotate the rotary shaft 20 To function.

In addition, the buoyancy body 40 is preferably formed to be heavier than the weight of the arc opening and closing plate 30 to maintain the open state of the arc opening and closing plate 30 by its own weight (Fig. 2 (A)). And shown in FIG. 3 (I)).

Here, the second connecting means 41 is a ring member 411 which is temporarily coupled to the center outer circumferential surface of the rotating shaft 20, a nut (N) fixed to the upper portion of the ring member 411, and the nut The long bolt 412 is fastened to (N) and the buoyancy body 40 is coupled to one end and the nut (N) is attached to the other end to the hollow tube 413 to guide the end of the long bolt 412 to the inside It is composed.

At this time, the protruding jaw 412a is formed at one end of the long bolt 412, and the other end of the hollow tube 413 is formed to be narrower than the inner diameter of the hollow tube 413 to prevent the long bolt 412 from being separated. Can be.

Here, the second connecting means 41 is forced to rotate only the long bolt 412 from the outside of the long bolt 412 and the hollow tube 413 according to the degree of insertion of the long bolt 412 to the hollow tube 413 The combined length can be adjusted (shown in FIGS. 4A and 4B).

This configuration is configured to control the degree of insertion of the hollow tube 413 by the direction of rotation of the long bolt 412 according to the size and weight of the arc-shaped opening and closing plate 30 and the inflow of rainwater and sewage with the rotation range. (Shown in FIGS. 4A and 4B).

In addition, the outer circumferential surface of the hollow tube 413 is attached to the bolt weight 60 to bias the weight is configured to be able to fine tune the weight with the hollow tube 413 is variable in length.

In addition, the ring member 411 is coupled to the rotary shaft 20 through the coupling pin (411a), which is the angle of the ring member 411 with respect to the rotary shaft 20 through the coupling pin (411a). By adjusting, as a result, a structure capable of adjusting the angle between the arc-shaped opening and closing plate 30 and the buoyancy body 40 is provided. This structure is intended to control the closing timing of the arc-shaped opening and closing board 30 according to the inflow of the initial rainwater flowing into the excellent soil chamber (shown in (A) and (B) of Figure 4).

The arc-shaped opening and closing plate 30 rotates through the second support rod 31 coupled to the rotation shaft 20 to open and close the sewage inlet 72.

The arc-shaped opening and closing plate 30 is a structure that is roundly curved to have the same radius of curvature as the rotation radius.

Here, the arc-shaped opening and closing plate 30 rotates back and forth according to the rotation of the rotating shaft 20 via the second support rod 31 to function to open or close the sewage inlet 72.

At this time, the second support rod 31 is vertically coupled to the rotary shaft 20, two fixing ring members 32 are fixed on the rotary shaft 20 for this purpose, the fixing ring member 32 The second support rod is coupled to the upper configuration.

The upper end of the second support bar is coupled to the bottom of the arc opening and closing plate 30 to provide a structure in which the arc opening and closing plate 30 can be rotated back and forth in conjunction with the rotation of the rotation shaft (20).

At this time, the second support rod 31 can also be configured to adjust the weight bias of the arc-shaped opening and closing plate 30 by coupling the bolt weight 60, of course.

On the other hand, the arc opening and closing plate 30 is configured to include an inner wall surface of the connecting frame 11 and the opening means attached to the other bottom surface of the arc opening and closing plate 30 so as to facilitate opening.

The opening means is composed of a permanent magnet 50, each of the permanent magnets 50 coupled to the frame 10 and the arc opening and closing plate 30 is attached to correspond to the same polarity.

For example, if the exposed polarity of the permanent magnet 50 coupled to the arc-shaped opening and closing plate 30 is negative (-), the exposed polarity of the permanent magnet 50 coupled to the frame 10 is also attached to show (-). It is.

Therefore, the excellent amount of the arc-shaped opening and closing plate 30 is to be opened, at this time, the interior of the rainwater chamber 70 is in a vacuum state, the opening of the arc-opening and closing plate 30 is delayed or does not open.

However, in the present invention, when the amount of rainwater decreases, the lifting response of the arc-opening and closing plate 30 is raised very rapidly by raising the arc-opening and closing plate 30 due to the same polarity of the permanent magnet 50, so that the sewage flows into the river. By preventing the pollution of rivers and rivers will be prevented.

6 and 7 is an operation view according to the cross-sectional view of the rainwater and earth and sand inlet prevention device having an arc opening and closing plate according to the present invention.

Prior to the description of the operation of the present invention, the present invention is composed of a structure in which each component is addressed to the frame 10, through which the sewage inflow hole 71 formed in the upper portion of the rainwater chamber 70 Only the frame 10 can be seated and installed.

Because of this, there is no need for a person to enter the storm soil 70 in order to install the present invention. This structure is to combine the arc-shaped opening and closing plate 30 and the buoyancy body 40 to the rotary shaft 20 is coupled downward on the frame 10 to minimize the reduction of the water passage cross-section inside the rainwater chamber 70, the sewage inflow Capacity can be increased.

First, as shown in FIG. 6, when the sewage is normally introduced along the sewage inlet 72, the water level inside the rainwater toil chamber 70 is constant, and the arc-opening and closing plate 30 is unbalanced in weight and buoyancy body 40. It is rotated forward by the floating height of) and is located on the bottom surface of the cover plate 13.

In addition, in the state where the water level inside the rainwater chamber 70 is low, the buoyancy body 40 is suspended in the air, and the arc-opening and closing plate 30 may be excessively rotated forward by the weight of the buoyancy body 40. The arc-shaped opening and closing plate 30 may be interrupted by a stopper plate 131 coupled to the bottom surface of the cover plate 13.

After the rain, the earth and sand can be introduced along the sewage inlet 72 with the rainwater. At this time, the water level of the rainwater tosoil 70 is increased by the initial rainwater flowing into the sewage inlet 72.

Then, as shown in FIG. 7, the buoyancy body 40 is raised as the initial amount of excellent rainfall in the stormwater chamber 70 increases, thereby rotating the rotation shaft 20 in a clockwise direction.

When the rotating shaft 20 is rotated, the second support rod 31 coupled to the rotating shaft 20 also rotates together with the rotating shaft 20 to rotate the arc-shaped opening and closing plate 30 backward.

The arc-shaped opening and closing plate 30 closes the sewage inlet 72 to prevent rainwater and earth and sand from entering the silt chamber.

Thereafter, the arc-opening and closing plate 30 is maintained in a closed state by the water pressure of rainwater even if the water level inside the rainwater toil chamber 70 is lowered.

And when the rainwater is reduced and the sewage flows as usual, the water pressure applied to the arc opening and closing plate 30 is weakened, the weight of the buoyancy body 40 and the arc opening and closing plate by the permanent magnet (50) 30 is rotated forward to open the sewage inlet 72.

Meanwhile, the present invention may be provided with a water barrier plate bent upward on both sides of the cover plate to induce sewage and rainwater, and the arc-opening plate also has a water barrier plate bent upward on both sides to drain rainwater and sewage to the surroundings. It can be configured to prevent it.
