Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid used for rain gutters of other households, other rainwater receivers, or rainwater basins for concentrating rainwater from the surface or the like.

[0002]

[Prior art]

 Conventionally, this kind of rainwater basin lid has a structure in which a relatively large long hole for a handle and for the entry of rainwater is opened, and rainwater enters the basin through the long hole of the rainwater basin lid. Then, it flows out to the downstream side through the mud reservoir at the bottom of the cell.

[0003]

[Problems to be solved by the device]

 However, since the rainwater basin lid has a structure in which a long hole is opened, insects such as mosquitoes may invade the mud reservoir of the basin through this long hole, resulting in burdock. Therefore, there is a problem that it becomes unsanitary.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a rainwater basin lid that can prevent invasion of insects and the like and can maintain good environmental hygiene.

【Example】

 An embodiment of the rainwater catcher lid of the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 4, reference numeral 1 is a rainwater catcher lid which is openably and closably fitted into an upper opening of a rainwater catcher 2 (FIG. 1) and has a diameter of, for example, 200 mm or less. The lid main body 3 is molded of a synthetic resin such as vinyl chloride, and has a large number of vertically extending water-permeable holes 4.

Reference numeral 5 denotes a net body made of synthetic resin or metal, and the net body 5 is provided on the upper surface of the lid main body 3 so as to be flush with the water permeable hole 4. That is, the bent outer edge portion 5a of the net body 5 is located above the outer edge portion 3a of the lid body 3 so that the upper surface of the net body 5 is flush with the upper surface of the outer edge portion 3a of the lid body 3. It is insert-molded and, as shown in FIG. 3, the net body 5 is pressed from above by a plurality of bosses 6. Note that FIG. 5 is a cross-sectional view of the net body 5.

The size of the mesh of the net body 5 must be small enough not to allow insects such as mosquitoes to pass through and large enough not to cause clogging by earth and sand. It is formed.

Further, the outer edge portion 3a of the lid body 3 is formed with a pair of notch holes 7 for a handle in the upper portion thereof, and an annular recess 9 into which an elastic ring body 8 is fitted is formed in a lower portion of the outer peripheral surface. Has been done.

In FIG. 1, reference numeral 11 denotes a basin body of the rainwater basin 2, and the basin body 11 is molded of synthetic resin, and receiving ports 12 and 13 having an enlarged diameter are formed on an upper side and a lower side, respectively. There are one outlet 14 and three inlets 15 (right side in FIG. 1), an inlet 16 (front side in FIG. 1) and an inlet 17 (back side in FIG. 1) in a substantially orthogonal shape. It is projected.

Reference numerals 18 and 19 are height adjusting tubes made of synthetic resin fitted in the receiving openings 12 and 13, respectively. A mud reservoir 21 is formed in the.

Reference numeral 22 denotes a lid receiving body that is fitted on the upper portion of the height adjusting tube 18. The lid receiving body 22 is made of synthetic resin, and the lid 1 can be freely opened and closed on the inner circumference of the upper portion. A lid receiving step portion 23 is formed to be fitted to the.

Reference numeral 24 is a mud reservoir container that is detachably arranged in the mud reservoir portion 21 of the basin body 11. The mud reservoir container 24 is molded of synthetic resin and has a substantially cylindrical bottom portion. , There is a handle 25 on the top.

Next, the operation of this embodiment will be described.

First, as shown in FIG. 1, the rainwater basin 2 having the above-described structure is installed at the installation site without the lid 1 and the mud container 24, and the three inflow ports 15, 16, 17 are installed. Connect the upstream pipe (not shown) to the required part, close the unused part with a cap (not shown), and connect the downstream pipe (not shown) to the outlet 14. To do.

Next, holding the handle 25, the mud reservoir container 24 is inserted from above the height adjusting pipe 18 and disposed in the mud reservoir portion 21. Next, after the elastic ring body 8 is fitted in the annular recess 9 of the lid body 1, the lid body 1 is fitted in the lid receiving step portion 23.

Then, drainage water such as rainwater containing sediment passes through the pipe body 5 on the upstream side and the net body 5 of the lid body 1 and the water permeation hole 4 and flows into the mud container 24 below the rainwater basin 2. Sediment is deposited on the bottom of the reservoir 24 to form a mud-like precipitate, and the supernatant wastewater flows out from the outlet 14 to the downstream side. Then, when the sediment is accumulated in the mud reservoir 24, the lid 1 is opened, the handle 25 is taken out to take out the mud reservoir 24, the sediment is discarded, and then the original position is set.

The net body 5 provided on the upper portion of the lid body 3 prevents insects and the like from entering the water permeable hole 4 of the lid body 3 and thus prevents insects and the like from entering the rainwater basin 2. Therefore, it is possible to maintain good environmental hygiene without the occurrence of burrs in the rainwater basin 2.

Further, since the net body 5 is provided on the upper surface of the lid body 3 in the same plane, the earth and sand accumulated on the upper surface of the lid body 1 can be easily removed by wiping it with a hand or a broom. be able to. Therefore, the water permeability of the lid 1 does not decrease, and the water permeability can be favorably maintained. On the other hand, as shown in FIG. 6, for example, if the net body 5 is provided below the upper surface of the lid body 3, it will be difficult to remove the sediment 26 accumulated in the corner 5b on the net body 5. Therefore, the water permeable area of the lid 1 is reduced and the water permeability is deteriorated, which is not preferable.

Further, as shown in FIG. 6, when the structure in which the net body 5 is provided below the upper surface of the lid body 3 is adopted, the outer edge portion 5a of the net body 5 is not bent and the lid body 3 is not bent. It is easy to insert in the middle part of the outer edge part 3a. On the other hand, in this embodiment, since the net body 5 is provided on the upper surface of the lid body 3 in the same plane and firmly, the outer edge portion 5a of the net body 5 is bent and the outer edge portion 3a of the lid body 3 is bent. It is inserted in the upper part of the to prevent the net body 5 from falling off.

Although the net body 5 having the shape shown in FIGS. 1 to 5 has been described in the above embodiment, the present invention is not limited to this. For example, as shown in FIG. It is possible to adopt various shapes, such as bending it to the end or further folding the tip portion 5e of the outer edge portion 5d as shown in FIG. Further, as shown in FIG. 9, a metal reinforcing material 27 is arranged under the metal net body 5, for example, in a cross shape, and the reinforcing material 27 is attached to the net body 5 by spot welding, The strength of the body 5 can be improved.

Further, the structure of the rainwater basin 2 to which the lid 1 of the present invention is fitted is not limited to the structure shown in FIG. 1, and one inflow port or two inflow ports can be arranged in various angular directions. The lid 1 of the present invention can be used for rainwater basins having various structures such as a structure provided or a structure having no inflow port at all.

[Effect of device]

 According to the first aspect of the present invention, the net body provided on the upper portion of the lid main body prevents insects and the like from penetrating into the water permeable hole of the lid main body and into the rainwater basin. Good environmental hygiene can be maintained without the occurrence of bobbing.

According to the second aspect of the invention, since the net body is provided on the upper surface of the lid main body in the same plane, the soil and sand accumulated on the lid for the rainwater basin can be easily removed with a broom or hand. . Therefore, the water permeability can be favorably maintained without reducing the water permeability area of the lid.
