Description

Drainage guidance device installed in the road drain

The present invention relates to a drainage induction device installed in a road drain, and more particularly, by maximizing the flow rate of a fluid such as rainwater discharged through a road drain, reducing the generation of foreign substances such as sludge, and rapid It relates to a drainage induction device installed in a road drain to enable drainage.

In general, underground sewers are installed at the edge of roads or sidewalks of general residential areas to allow rainwater or fluid discharged from homes, factories, and shops, that is, sewage to flow, and rainwater into the underground sewers at regular intervals on the ground along the underground sewers. A drain hole (hereinafter referred to as a'road drain') is installed to allow the inflow.

A drain cover (or'grating') is installed in the road drain to prevent the safe movement of pedestrians or vehicles and the inflow of various foreign substances into the drain. In general, an odor blocking device is installed under the drain cover to block the outflow of odors or pests generated from the underground sewer to the outside through the drain.

Basically, the odor blocker has a structure that is normally blocked to block odors and pests from coming up from the underground sewer to the ground through the road drain, and has a structure that is opened when fluid such as rainwater enters through the road drain. do.

That is, the odor blocking device has a structure including an outlet formed toward the underground sewer and an opening and closing plate for opening and closing the outlet, and a kind of path through which fluid flows toward the outlet is generally formed according to this structure.

1 and 2 are views showing the'Structure of a sewage inducing body of a drainage outlet' disclosed in Korean Utility Model Publication No. 20-0398817.

As shown in Figs. 1 and 2, rainwater is accelerated along a downwardly inclined downward slope along the top of the sewage guide mounted on the drain and discharged through a side opening that is opened and closed with an opening and closing plate at the end of the downwardly inclined surface. By doing so, the sewage such as rainwater flowing into the sewage guide can be quickly discharged, and when there is no discharge of rainwater, the side openings are closed by the opening and closing plate, so that the odor of the wastewater in the drainage is odor to the outside through the drainage port. The sewage guide of the drain can completely block the occurrence and prevent damage by applying excessive force to the sewage guide of the drain by naturally opening the opening and closing plate when the sewage or dry water in the sewage pipe flows back. Regarding the structure of, in forming a sewage guide in which an opening and closing plate is formed in the drain, form a downwardly inclined downwardly inclined surface 140 around the corner branching surface 130 in the sewage guide 100, and the downwardly inclined surface ( An opening and closing plate 160 that can flow around a hinge 161 is formed above the opening 150 in which the end portion of the 140 is opened, and a downwardly inclined surface ( The reverse flow opening/closing plate 200 is formed on the upper surface of the 140, and the opening 150 at the top of the opening 150 where the end of the downwardly inclined surface 140 is opened, and the opening and closing plate 160 that can flow around the hinge 161 Bugu wing 180 is formed.

However, the existing odor blocking device is composed only of a structure that allows fluid such as rainwater to simply flow to the outlet side along the slope, as in the above'Structure of the sewage inducer at the drain outlet', so the flow velocity of the fluid depends only on the slope. There is a problem with this not being fast.

This problem is that, when the amount of fluid is small, foreign substances contained in the fluid remain in the odor blocking device and act as a cause of the generation of sludge, and such sludge generates odor, which causes hygiene problems as well as flow rate. It not only encourages the generation of sludge by lowering the temperature, but can also develop as a cause of clogging the outlet itself.

In particular, as shown in Fig. 3, the fluid falling in the direction ① collides with the fluid flowing in the direction ② and lowers the flow rate, which increases the clogging of the road drain when a large amount of fluid flows in. It will be able to work.

Accordingly, the present invention was devised to solve the above problems, and the flow rate of fluid such as rainwater discharged through the road drain is maximized to reduce the occurrence of foreign substances such as sludge, and rapid drainage is possible even when a large amount of fluid is introduced. It is an object of the present invention to provide a drainage guide device installed in a road drain that enables it.

The above object is, according to the present invention, in the drainage induction device installed in the road drain, the body plate seated on the road drain, and the body plate formed in the lower direction of the body plate to flow into the road drain. At least one fluid flow guide portion for guiding a fluid to a lower portion of the road drain; The fluid flow guide portion is provided in the form of an outlet located in the lower region of the main plate and a water slide that rotates downwardly while drawing an arc from the main plate toward the outlet, so that the fluid flowing into the road drain is directed toward the outlet. It is achieved by a drainage guiding device installed in a road drain, characterized in that it comprises a vortex forming slide portion for guiding the flow of the fluid to form a vortex of the shape.

Here, it may further include an opening/closing plate installed to be rotatable in an upward direction in the fluid flow guide unit to open and close the outlet.

In addition, when a plurality of fluid flow guide units are provided, the plurality of fluid flow guide units are formed along a circumferential direction around a central axis in the vertical direction, so that the vortex forming slide unit forms an arc at a predetermined angle around the central axis. can do.

In addition, the vortex formation slide portions of the plurality of fluid flow guide units may be provided such that the vortex formation direction is formed in the same direction in either a clockwise direction or a counterclockwise direction with respect to the central axis.

In addition, the eddy current-forming slide portion may have a curved shape in which an inclination toward the discharge port decreases toward an outer side in a radial direction from the central axis.

In addition, when the fluid flow guide unit is provided as one, the outlet is formed below the upper starting point of the vortex forming slide unit, so that the vortex forming slide unit rotates downward along the central axis to the starting point and the discharge port. Can be provided.

A cutaway view of a partial area of the drainage induction device 100 installed in the drainage port 200, and FIG. 6 is a bottom surface of the drainage induction device 100 installed in the road drainage port 200 according to the first embodiment of the present invention. It is a perspective view.

4 to 6, the drainage induction device 100 according to the present invention includes a

body plate

110 and 111 and at least one fluid

flow guide portion

130 and 140. In the embodiments shown in FIGS. 4 and 6, it is an example in which two fluid

flow guide units

130 and 140 are formed, but the technical idea of the present invention is not limited thereto, and it will be apparent through description to be described later.

The

body plates

110 and 111 are seated in the road drain 200. The

main body plates

110 and 111 are seated on the jaws 210 (see FIGS. 9 and 10) of the road drain 200, and as shown in FIGS. 4 and 6, the seating portion 110 that is seated on the road drain 200 ), and a stepped portion 111 stepped downward from the seating portion 110.

The fluid

flow guide units

130 and 140 are formed on the

body plates

110 and 111, and are formed in the lower direction of the

body plates

110 and 111 to guide the fluid flowing into the road drain 200 to the lower portion of the road drain 200. As described above, in the first embodiment of the present invention, as an example, the two fluid

flow guide units

130 and 140 are formed. For convenience of explanation, the'first fluid flow guide unit 130' and the'second fluid flow guide unit 130' It is defined as'induction part 140'.

The first fluid flow induction part 130 includes a first outlet 132 and a first vortex formation induction part.

The first outlet 132 is located in the lower region of the

body plates

110 and 111. In addition, the vortex forming slide portion is provided in the form of a water slide that rotates downward while drawing an arc from the

body plates

110 and 111 toward the outlet. Through this, when a fluid such as rainwater flowing into the road drain 200 flows toward the outlet, the flow of the fluid is guided by the vortex-forming slide portion to form an arc-shaped vortex while flowing along the vortex-forming slide portion.

According to the above configuration, when compared with the drainage induction device 100, such as a conventional odor blocking device, which consists of only an inclined surface or has some curves, the fluid forms an arc-shaped vortex along the water slide-shaped vortex-forming slide. It can be discharged to the outlet while forming, so that the fluid can be discharged at a faster flow rate.

Accordingly, due to the fast flow rate, not only can the phenomenon of the occurrence of sludge in the vortex forming slide portion be significantly reduced, but also the rapid discharge can be performed even when a large amount of fluid is introduced, thereby remarkably reducing the clogging phenomenon.

In addition, when the fluid flows by forming an arc-shaped vortex, the angle formed by the fluid in both directions is compared with the prior art even if the fluid falls from the step portion 111 of the

body plate

110 and 111 to the vortex forming slide portion in any direction. As a result, the resistance due to the collision of the fluid in two directions is significantly reduced, and the fluid flow can be maintained smoothly.

The second fluid flow guide unit 140, like the first fluid flow guide unit 130, has a second outlet 142 located in the lower region of the

body plates

110 and 111, and a second wagyu forming slide provided in the form of a water slide. Including the unit, the same functions and effects as the first fluid flow inducing unit 130 are provided.

Here, the first fluid flow guide unit 130 and the second fluid flow guide unit 140 are formed along a circumferential direction around a central axis in the vertical direction, as shown in FIGS. 4 and 6. In addition, it is assumed that the first vortex-forming slide part 131 and the second vortex-forming slide part 141 form arcs at a predetermined angle around a central axis. That is, the first vortex-forming slide portion 131 forms an arc of 180° out of 360°, and the second vortex-forming slide portion 141 forms the remaining 180° arc. If three fluid flow guide units according to the present invention are provided, each vortex forming slide unit may be provided to form an arc of 120°.

In addition, in the first vortex forming slide part 131 and the second vortex forming slide part 141, the vortex forming direction, that is, the flow direction of the fluid flowing while drawing an arc, is in one of a clockwise direction and a counterclockwise direction with respect to the central axis. It may be provided to be formed in the same manner. In the embodiment illustrated in FIG. 4, for example, the eddy current is provided to be formed in a clockwise direction, but it is of course possible to configure it to be formed in a counterclockwise direction.

4 and 5, the first vortex-forming slide part 131 and the second vortex-forming slide part 141 according to the first embodiment of the present invention are first It has a curved shape in which the inclination toward the discharge port 132 and the second discharge port 142 is lowered. That is, as the length of the arc decreases toward the central axis, a sharp slope is maintained in the direction of the first discharge port 132 or the second discharge port 142, and conversely, the length of the arc increases toward the outside. 2 The slope in the direction of the outlet 142 is formed smoothly.

On the other hand, the drainage induction device 100 according to the first embodiment of the present invention is installed to be rotatable upwardly in the first fluid flow induction part 130 and the second fluid flow induction part 140, and the first outlet 132 and It may include an opening and closing plate 151 for opening and closing the second outlet 142, respectively. In FIG. 6, only the opening/closing plate 151 for opening and closing the second outlet 142 is shown, but the opening/closing plate 151 for opening and closing the first outlet 132 may also be installed in the same manner.

Here, the opening/closing plate 151 is installed to be freely rotatable in the first fluid flow induction part 130 and the second fluid flow induction part 140, and the first vortex formation slide part 131 and the second vortex formation slide part ( It can be opened automatically by the flow of the fluid flowing through 141).

In addition, the opening/closing plate 151 is made of synthetic resin such as foamed polyurethane, polypropylene, and AS resin, which has a lower specific gravity than water so that the first outlet 132 and the second outlet 142 can be automatically opened by rising by buoyancy. It can be made of a material. That is, when water is filled in the sewer under the road drain 200, the opening/closing plate 151 rotates and floats due to buoyancy, so that it is possible to naturally induce reverse flow to prevent flooding.

Meanwhile, in the present invention, for example, the first vortex forming slide part 131 and the second vortex forming slide part 141 form mutually independent spaces through the partition wall 120. In addition, the first discharge port 132 and the second discharge port 142 have a shape positioned below the partition wall 120, respectively, so that the first fluid flow guide unit 130 and the second fluid flow guide unit 140 are independent. It becomes possible to operate with.

The vortex forming slide portion 131a is formed in a rotating form.

Through this, the fluid flowing into the road drain 200 can flow toward the discharge port 132a at a fast flow rate through the vortex forming slide part 131a.

Here, the drainage induction device 100a according to the second embodiment may also include a partition wall 120a and an opening/closing plate 151a. Here, the partition wall 120a does not perform a function of dividing the two zones, and the outlet 132a is located under the partition wall 120a, as in the first embodiment.
