Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a deodorizing device for a rainwater basin provided in a gutter of a road or the like, and more particularly, to a deodorizing device for a rainwater basin that prevents the odor of sewage from the rainwater basin from being released into the atmosphere.

[0002]

[Prior art]

 A rainwater basin is installed in the gutter of the road, etc., and the rainwater flows into the storm gutter from the gutter. A sewer pipe buried underground is connected to the rainwater basin, and the rainwater in the rainwater basin is drained through the sewer pipe.

In general, a rainwater basin comprises a box-shaped concrete basin body having an opening on the upper surface, and a lid detachably provided at the opening of the basin body. A water passage section is provided.

Meanwhile, sewage such as household wastewater also flows into the sewage pipe, so that the odor of the sewage flows back to the rainwater basin and diffuses into the atmosphere from the water passage of the lid, deteriorating the surrounding environment. You may be forced to do so.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. H11-350583, it has been proposed to provide a deodorizing device for preventing the emission of offensive odors from sewage on the lower surface side of a lid in a rainwater basin. This deodorizing device is provided with a container-shaped tray that is swingable on the lower surface side of the lid, facing the water passage section, and normally closes the water passage section with this tray to prevent the emission of offensive odors. Rainwater is received in the tray through the water passage, and when a certain amount of rainwater accumulates in this tray, the weight of the tray is swung downward to allow the internal rainwater to flow into the rainwater basin. I have.

[0006]

[Problems to be solved by the invention]

 However, in this deodorizing device, when light garbage such as cigarette butts is thrown into the tray through the water passage of the lid at normal times, the weight of the garbage is light. The garbage stays in the pan without swinging.

When the staying state is over a long period of time, the dust is solidified on the inner surface of the tray, and the dust is deposited on the rocking fulcrum of the tray by such solidification, and the rocking operation of the tray is performed. As a result, problems such as a reduction in the deodorizing effect and incomplete drainage may occur.

The present invention has been made in view of such a point. The purpose of the invention is to prevent light-weight garbage such as cigarette butts from entering the rainwater basin. It is an object of the present invention to provide a deodorizing device for a rainwater basin which can be quickly dropped into a main body of the basin to prevent its consolidation and always maintain an appropriate odor prevention and drainage effect.

[0009]

[Means for Solving the Problems]

 In order to achieve such an object, this invention has an opening in the upper part, the inside of which is connected to a sewer pipe, and a basin that is provided in the opening of the basin and allows rainwater to flow into the basin. A lid body having a water passage portion to be passed, a guide tube attached to the lower surface of the lid body surrounding the water passage portion, and having a discharge port formed at a lower end portion obliquely inclined with respect to a vertical surface; A flat shielding plate provided at the discharge opening of the guide tube so as to be openable and closable, and the shielding plate is supported by a hinge at an upper end edge of the discharge opening so as to be rotatable around a horizontal axis. The urging member urges the discharge port in a direction in which the discharge port is closed, and closes the discharge port in an inclined position.

[0010] In particular, the invention according to claim 2 is characterized in that the lid is detachably provided in the opening of the basin main body, and is connected to the basin main body by a connecting strip for preventing jumping. I have.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of the upper part of the rainwater basin 1. The rainwater basin 1 has a box-shaped concrete basin body 3 having an opening 2 in the upper part and the opening part 2 of the basin body 3. And a lid 4 made of concrete provided. The basin body 3 is buried underground, and a sewer pipe (not shown) is connected to a side surface or the like.

A fitting groove 5 is formed on an inner side of one side of the upper portion of the main body 3, and a step 6 is formed on an upper surface of the remaining three sides. One side of the lid 4 is inserted into the fitting groove 5, and the remaining three sides are fitted to the stepped portion 6 and detachably attached to the opening of the box body 3.

The cover 4 is formed with, for example, two elongated through holes 7 as water passage portions in parallel, and rainwater flows into the tub body 3 through these through holes 7.

A plate 10 is attached to the lower surface of the lid 4, an opening 11 facing the region including the through hole 7 is formed in the plate 10, and a guide cylinder 12 is attached to the lower surface of the plate 10. .

As shown in FIG. 2, the guide cylinder 12 is formed in a cylindrical shape from three vertical side plates 12a, 12b, and 12c and one side plate 12d inclined with respect to the vertical plane. Is provided with a discharge port 13 having an opening surface inclined at the same angle as the inclined side plate 12d.

The discharge port 13 is provided with a shield plate 14 for opening and closing the discharge port 13, and the shield plate 14 is turned at the upper edge to the upper edge of the discharge port 13 via a hinge 15 having a pin 15 a. The discharge port 13 is movably mounted, and is opened and closed by rotating about a horizontal axis about the pin 15a as a fulcrum.

An extension plate 16 extending substantially horizontally toward the outside of the guide cylinder 12 is integrally provided at an upper edge portion of the shielding plate 14, and a bolt 17 is attached to a lower surface of the extension plate 16. ing.

A number of disc-shaped adjustment weights 18 having a through hole in the center are inserted into the bolts 17, and these weights 18 are attached and detached via nuts 19 screwed to the bolts 17. A biasing member which is supported so as to be able to bias the shielding plate 14 by the bolts 17, the weights 18, and the nuts 19 is provided. The biasing member applies the shielding plate 14 with a light force in the counterclockwise direction in FIG. The shielding plate 14 is closed by the urging force to the outlet 13 and is held in a posture inclined with respect to the vertical plane. By increasing or decreasing the number of the weights 18, the biasing force of the shielding plate 14 in the counterclockwise direction can be finely adjusted.

Further, the lid 4 detachably provided in the opening 2 of the basin main body 1 is connected to the basin main body 1 by a connecting strip 20 made of a chain or the like for preventing jumping, so that a vehicle or the like travels. Safety measures are taken to prevent the lid 4 from detaching from the opening 2 and jumping greatly due to impact or the like.

In such a rainwater basin 1, the discharge port 13 is normally closed by the shielding plate 14, so that the emission of offensive odor from sewage to the atmosphere is suppressed. When rainwater flows into the basin body 3 from the through-hole 7 of the lid 4 during rainfall, the weight of the rainwater causes the shielding plate 14 to rotate clockwise to open the discharge port 13, As a result, rainwater is sequentially discharged into the main body 3 of the basin.

On the other hand, when light dust, such as cigarette butts, falls into the box body 3 through the through hole 7 of the lid 4 in fine weather or the like, the dust slides on the inclined shielding plate 14. It reaches inside the lower end of the shielding plate 14.

The upper end of the shielding plate 14 is used as a fulcrum, so that a large moment is applied to the shielding plate 14 by disposing dust inside the lower end of the shielding plate 14, and the shielding plate 14 is light. Since only the force is urged in the counterclockwise direction by the force, as the debris moves inside the lower end side of the shielding plate 14, the shielding plate 14 supports the pin 15a of the hinge 15 by the weight of dust. , And smoothly and accurately rotate clockwise, and the outlet 13 is opened. Then, the dust is dropped and discharged from the guide tube 12 into the box body 3 by this opening.

After the dust is discharged, the shielding plate 14 rotates counterclockwise by the urging force of the weight 18 or the like, closes to the discharge port 13 and returns to the original inclined state.

As described above, even when light dust such as cigarette butts falls from the through-hole 7 of the lid 4, the shielding plate 14 is accurately rotated each time the dust is removed from the guide cylinder 12. The waste is quickly discharged from the inside into the main body 3, so that solidification due to long-term accumulation of dust can be prevented, and the shielding plate 14 can always be properly operated to maintain an appropriate deodorization and drainage effect.

As the lid of the rainwater basin, in addition to the case of using the concrete lid as in the above-described embodiment, it is also possible to use a lattice-shaped lid having a high aperture ratio and a grating structure. In this case, the mesh of the lattice is a water passage, and a guide cylinder is provided on the lower surface of the lid so as to surround the water passage.

[0026]

[Effect of the invention]

 As described above, according to the present invention, even if light trash such as cigarette butts enters the rainwater basin, it falls quickly into the main body of the basin by rotating the shielding plate. Therefore, it is possible to prevent solidification of refuse and always maintain proper deodorization and drainage effects.

In particular, according to the invention of claim 2, since the lid is connected to the box body by the connecting strip for preventing jumping, a large impact or the like is applied to the lid when the vehicle or the like travels. Even if it does, the large jump of the lid can be suppressed to avoid unexpected danger.
