2 is a view illustrating a state in which the rainwater inflow prevention apparatus 100 according to an embodiment of the present invention is installed, and illustrates a state in which the blocking plate 120 of the rainwater inflow prevention apparatus 100 is closed.

Referring to FIG. 2, the rainwater inflow prevention device 100 according to the present embodiment is installed at an upper portion of the collecting conduit 200. The collection pipe 200 is vertically connected to the sewage inflow passage 190. In addition, the sewage inflow passage 190 is provided with a guide plate 180 to allow the sewage to flow onto the rainwater inflow prevention device 100, and the guide plate 180 includes a screen 182 for filtering various wastes. It is provided. And part of the upper part of the housing 200 is covered by a shielding plate (210).

Sewage discharged from the home and the like flows in the direction of the river through the sewage inflow passage 190, and flows onto the blocking plate 120 of the rainwater inflow prevention device 100 by the guide plate 180. In the process of filthy water flowing on the collecting plate 120, the screen 182 is filtered through various wastes, etc., and then flows into the rainwater inflow preventing device 100 located on the collecting conduit 200.

The collector plate 120 of the rainwater inflow prevention device 100 is closed in the case of rainwater and rainwater mixed with sewage and rainwater. It is opened when mixed with the following rainwater. This will be described in more detail below.

When the collecting plate 120 is closed, since the blocking plate 120 blocks the entrance of the collecting conduit 200, the sewage flows into the river after passing through the collecting plate 120. And when the collecting plate 120 is open, since the inlet of the collecting conduit 200 is open, sewage is introduced into the collecting conduit 200 is introduced into the sewage treatment device (not shown).

Hereinafter, the rain inflow prevention apparatus 100 according to the present embodiment will be described with reference to FIGS. 3 to 6.

3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is a front view of the rainwater inflow prevention device 100 according to the present embodiment.

3 to 4, the rainwater inflow prevention device 100 according to the present embodiment may include a car collecting plate 120 and a car collecting plate 120 located at an open upper portion of the tea collection conduit 200. Hinges 152 and 154 as supporting rotational supports, central axis 160 and support 164. In addition, a tube 128 is provided at a lower portion of the blocking plate 120, and a moving weight 134 is provided inside the tube 128 to smoothly rotate the blocking plate 120. In addition, an extension plate 170 is provided in an inflow direction (shown by an arrow in FIG. 3) based on the collector conduit 200, and a part of the extension plate 170 protrudes to an open upper portion of the collector conduit 200. It is intended to be in contact with 120. And the extension plate 170 is provided with a locking member 172 to prevent excessive rotation of the blocking plate 120.

The rotatable support for rotatably supporting the collecting plate 120 includes a support 164 fixed to the collecting conduit 200, a central axis 160 disposed perpendicularly to the support 164, and a central axis 160. ) And hinges 152 and 154 connecting the blocking plate 120.

One or more supports 164 may be provided to support one blocking plate 120. 3 to 4 illustrate that the support 164 is fixed to the bottom of the dwelling 200, the support 164 may be fixed to an inner side of the dwelling 200.

The central shaft 160 is fixed to the end of the support 164 and has a circular cross section. The central axis 160 is to be the center of rotation of the blocking plate 120, the fixed hinge 152 and the insertion hinge 154 is coupled as described below.

5A and 5B are views illustrating a state in which the fixed hinge 152 and the insertion hinge 154 are coupled to the blocking plate 120, respectively. FIG. 5A is a cross-sectional view taken along line BB of FIG. 4, and FIG. 5B is a view of FIG. It is sectional drawing along the CC line | wire of 4.

The fixed hinge 152 and the insertion hinge 154 rotatably connect the blocking plate 120 to the central axis 160 to enable rotation of the blocking plate 120. The fixed hinge 152 and the insertion hinge 154 are coupled to the lower portion of the blocking plate 120 by bolts inserted into the through holes 124 formed in the blocking plate 120. The fixed hinge 152 and the insertion hinge 154 may be made of Teflon to increase durability in water. Since Teflon has excellent chemical resistance, it is advantageous in that it is not modified or eroded by chemicals or toxic substances contained in sewage. In addition, since the heat resistance and cold resistance is excellent, there is an advantage that does not easily deform even in the change of temperature.

Referring to FIG. 4, it can be seen that one fixed hinge 152 is coupled to the center of the blocking plate 120, and one insertion hinge 154 is coupled to each of the left and right sides of the fixed hinge 152.

The fixed hinge 152 is such that the blocking plate 120 does not fall with respect to the central axis 160, and a hole into which the central axis 160 is inserted is formed at the center thereof. And the insertion hinge 154 has a c-shape to be able to insert the central axis 160 through the open portion. The insertion hinge 154 facilitates detachment of the blocking plate 120 with respect to the central axis 160. That is, when the fixed hinge 152 coupled to the center of the blocking plate 120 is removed, the central axis 160 can be easily removed from the left and right insertion hinges 154.

6A and 6B are a plan view and a side view of the blocking plate 120 according to an embodiment of the present invention. 6C is a cross-sectional view taken along the line DD of FIG. 6A.

6A to 6C, the collecting plate 120 has a rectangular shape corresponding to the upper inlet shape of the collecting conduit 200, a body portion 122 rotatably coupled to a rotation support portion, and a body portion ( And a contact portion 146 extending from the body portion 122 in the inflow direction (see FIG. 3) in the stream direction (see FIG. 3).

A fixed hinge 152 and a rotating hinge 154 are coupled to the lower surface of the body portion 122 as illustrated in FIGS. 3 and 4. In the body portion 122, two through holes 124 are formed in three groups. A screw is inserted into each through hole 124 to couple the fixed hinge 152 or the rotary hinge 154 to the body portion 122.

The through hole 124 has a certain distance so that the screw can move in a straight line therein. Therefore, since the fixed hinge 152 and the insertion hinge 154 can be adjusted to the position coupled to the body portion 122, it is possible to easily set the center of gravity of the collector plate 120 with respect to the central axis (160). . And due to the configuration of the through-hole 124 having a predetermined length, it is possible to easily change the position of the blocking plate 120 in the river direction or inflow direction.

A pair of tubes 128 is coupled to the lower portion of the body portion 122 symmetrically from the center thereof. The tube 128 is a hollow tube, and a moving weight 134 is inserted into the tube 128 to facilitate the rotation of the blocking plate 120. Since the tube 128 has a certain length, the moving weight 134 included therein can move in the longitudinal direction of the tube 128.

An inclined surface 132 is formed inside the tube 128 as illustrated in FIG. 3. The inclined surface 132 is formed to be inclined downward in the river direction. Therefore, when the collector plate 120 is horizontal, the moving weight 134 moves in the river direction by the inclined surface 132. When the rainwater input flow increases, the collector plate 120 becomes horizontal. As the moving weight 134 moves in the direction of the river by the inclined surface 132, it is easy to rotate the closing plate 120 to be closed.

Since the moving weight 134 has a constant weight and has a spherical shape, the moving weight 134 can be easily moved inside the tube 128. The weight and number of the moving weights 134 may vary depending on the weight and size of the blocking plate 120 and the flow rates of storm water and sewage.

The inclined portion 138 corresponds to a surface formed to be inclined upward in the river direction at the end of the body portion 122. As illustrated in FIG. 7B, when the blocking plate 120 is leveled by rainwater, the inclined portion 138 is pressured by rainwater flowing in the river direction. In this manner, the blocking plate 120 can maintain the closed state by the excellent pressure applied to the inclined portion 138. And when the blocking plate 120 is close to horizontal, the closing of the blocking plate 120 in a horizontal state is accelerated by the pressure applied to the inclined portion 138.

The contact portion 146 corresponds to a surface extending in the inflow direction at the end of the body portion 122. As illustrated in FIG. 7B, when the blocking plate 120 is leveled by rainwater, the contact portion 146 is in contact with the extension plate 170. As illustrated in FIG. 7A, when the rain shield plate 120 is opened because rainwater does not flow in, the contact portion 146 is caught by the locking member 172. For this reason, the rotation angle of the blocking plate 120 is limited and the case of being excessively open is prevented.

At each corner end of the blocking plate 120, bent portions 136, 142, and 148 folded inward are formed. The bent portions 136, 142, and 148 reinforce the strength of the blocking plate 120 having a plate shape.

The extension plate 170 corresponds to a plate protruding into the upper opening of the collecting conduit 200. As illustrated in FIG. 7B, the extension plate 170 is in contact with the contact part 146 when the blocking plate 120 is closed to completely close the upper opening of the collecting conduit 200. In addition, the contact part 146 is caught by the extension plate 170 when the blocking plate 120 is horizontal, thereby preventing the blocking plate 120 from rotating in the clockwise direction in FIG. 3.

In addition, the engaging member 172 is coupled to the extension plate 170. The catching member 172 protrudes downward from the inside of the collecting conduit 200, and a hook is formed at the end thereof so that the contact part 146 may be caught. And the locking member 172 may be configured by a bolt or the like to adjust the length.

As illustrated in FIG. 7A, when the collecting plate 120 is opened, the sewage falls directly from the extension plate 170 to the collecting conduit 200, where the sewage falls toward the contact portion 146. At this time, the locking member 172 to be caught by the contact portion 146 serves to prevent the blocking plate 120 from being excessively open.

Hereinafter, referring to FIGS. 7A and 7B, the operation of the rainwater inflow prevention device 100 according to the present embodiment will be described.

7A is a view illustrating a state in which the collector plate 120 is opened when only sewage is introduced or rainwater of a predetermined amount or less flows in. It is an illustration to illustrate.

Referring to FIG. 7A, when rainwater does not flow, such as a clear day, or when rainwater of a certain amount or less flows in, filthy water or a mixture of filthy water and rainwater passes through the extension plate 170 and then refers to the central axis 160. As it will fall on the blocking plate 120 located in the inflow direction. As a result, the contact portion 146 moves downward by the hydraulic pressure, the inclined portion 138 moves upward, and the blocking plate 120 is opened. By opening the collecting plate 120, the upper part of the collecting conduit 200 is opened, and the sewage or the mixture of the sewage and rainwater flows into the collecting conduit 200 and flows to a sewage treatment plant (not shown).

When the blocking plate 120 is rotated and opened as shown in FIG. 7A, the moving weight 134 inside the tube 128 is also moved in the inflow direction. As such, when the contact portion 146 rotates about a certain degree, the moving weight 134 is automatically deflected in the inflow direction inside the tube 128, thereby facilitating the rotation of the blocking plate 120. In addition, since the moving weight 134 has a constant weight, it also serves to prevent the once-opened blocking plate 120 is easily closed.

When the blocking plate 120 is opened, the blocking plate 120 may be excessively opened by the pressure of filth or a mixture of filthy water and rainwater falling onto the blocking plate 120. In order to solve such a problem, the contact portion 146 is caught by the locking member 172 to prevent the blocking plate 120 from being excessively open.

Referring to FIG. 7B, when the rainwater flows in a predetermined amount or more, the inclined portion 138 is lowered and the contact portion 146 is raised by the hydraulic pressure applied to the inclined portion 138. As a result, the blocking plate 120 is closed to close the upper portion of the collecting conduit 200. By closing the upper portion of the collecting pipe 200, a mixture of rainwater and sewage of a predetermined amount or more is discharged to the river passing through the collecting plate 120. When the collecting plate 120 is closed, the portion located in the river direction in the collecting plate 120 is caught by the upper end 220 of the collecting pipe 200, the contact portion 146 is caught by the extension plate 170. .

And when the blocking plate 120 starts to rotate clockwise in the open state as shown in FIG. 7A, the moving weight 134 located inside the tube 128 also begins to roll in the river direction. As a result, the process of rotating the blocking plate 120 in the closed state becomes easier. And since the inclined portion 138 is continuously receiving pressure due to the sewage flowing in the river direction and a certain amount or more, the blocking plate 120 is counterclockwise when a flow rate of a predetermined amount or more flows after the blocking plate 120 is closed once. It becomes difficult to rotate in the direction to be in an open state.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
