DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain cover having a grating for covering the drain.

[0002]

2. Description of the Related Art In this kind of drainage lid, rainwater or the like drops into the drainage groove through the grating-shaped openings of the grating, so that rainwater or the like can be effectively drained to the drainage groove.

[0003]

However, in the drain cover provided with the grating, the odor of the sewage flowing in the drain diffuses to the outside of the drain through the opening of the grating, and the periphery of the drain is surrounded. There may be a strange odor. In view of such problems, it is an object of the present invention to provide a drain groove lid that can prevent odors generated in the drain groove from diffusing to the outside of the drain groove.

[0004]

A drainage channel lid according to the present invention is provided with a grating at the top opening of a box to be buried in the drainage channel to form a drainage port at the bottom of the box, and from the drainage port to the inside of the box. A partition wall is provided upright to partition a water storage section around the drainage port on the bottom surface and side surfaces of the partition wall and the box, and a cylindrical lid having an opening at the lower end is covered from the upper end of the partition wall. The lower end of the lid is hung into the water storage section to partition the water storage section into an outer water storage section and an inner water storage section communicating with the outer water storage section at the bottom, and the lid body and the upper end of the partition wall. A gap is formed between the inner water storage portion and the drainage port.

[0005]

According to the above-described structure, the rainwater that has dripped into the inside of the box through the grating flows along the surface of the lid body into the water storage section and collects in the water storage section. When the water reservoir fills with rainwater and rainwater further drips into the box, the rainwater in the inner water reservoir passes over the upper edge of the partition wall and flows into the drain port through the gap formed between the lid and the upper edge of the partition wall. Then, it flows out from the drain to the drain. On the other hand, the odor of sewage flowing in the drainage channel penetrates into the inside of the partition wall from the drainage port and reaches the gap formed between the lid and the upper end of the partition wall, but collects in the inner water storage part communicating with the gap. The rainwater prevents odors from entering the outer reservoir. Therefore, the odor can be prevented from diffusing through the grating to the outside of the box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention will be described below with reference to the drawings.
Also, FIG. 2 shows a drain cover 10 according to an embodiment of the present invention. The drain gutter lid 10 includes a box body 11 embedded in the drain gutter, and a grating 12 is attached to an upper surface opening 11 a of the box body 11.
The grating 12 has a plurality of bearing bars 13 which are arranged at equal intervals and whose ends are welded and fixed to the side surface of the box body 11, and a cross bar 14 orthogonal to the bearing bars.
It is composed of Box body 11 has an opening 1 on the bottom
1b, and a bottom cover 15 is fixed to the opening 11b with bolts 16. A drain port 15a is formed in the bottom cover 15, and a partition wall 15b that stands up from the drain port 15a to the inside of the box body 11 is provided.
A water storage section 17 is defined by the partition wall 15b, the bottom surface of the bottom cover 15 and the side surface of the box body 11. A cylindrical lid 18 having an opening at the lower end is covered on the upper end surface of the partition wall 15b. A projection 15c is integrally provided on the upper end of the partition wall 15b so that a gap 19 is formed between the lid 18 and the upper end of the partition wall 15b. The lower end of the lid 18 is suspended in the water storage section 17, and divides the water storage section 17 into an outer water storage section 17a and an inner water storage section 17b communicating with the outer water storage section 17a at the bottom. Since the drain groove lid 10 according to the present embodiment has the above-described configuration, rainwater that has dripped into the inside of the box body 11 through the grating 12 has a lid body 1.
It flows along the surface of No. 8 into the water storage section 17, and accumulates in the water storage section 17. When the water reservoir 17 is filled with rainwater, and rainwater further drops into the box body 11, the rainwater in the inner water reservoir 17a gets over the upper end of the partition wall 15b and flows into the drainage port 15a through the gap 19 to drain the drainage port 15a. Drains into the drain. On the other hand, the odor of sewage flowing in the drainage channel is the drain port 15a
From the inside to enter the inside of the partition wall 15b, and the lid 18 and the partition wall 1
Although it reaches the gap 19 formed between the upper end of 5b,
Rainwater collected in the inner water storage portion 17b communicating with the gap 19 prevents odors from entering the outer water storage portion 17a.
As a result, the odor of the wastewater in the drain can be prevented from diffusing through the grating 12 to the outside of the drain lid 10. Next, a drain groove lid according to another embodiment of the present invention is shown in FIGS. In the drain groove lid 20, a metal net 21 is stretched on the surface of the grating 12, and a water-permeable surface layer 22 formed by binding an aggregate with a binder is laid on the net 21. Note that other configurations are shown in FIGS.
Since it is the same as the embodiment shown in FIG. 5, the same components are assigned the same reference numerals and explanations thereof are omitted. According to the present embodiment, in addition to preventing the diffusion of odors, the appearance of the surface layer 22 is laid, so that the appearance is improved and the anti-slip effect during walking is improved.
