Description

The present invention relates to a pest controller for a drainage basin used for a drainage basin installed in a gutter on a road or underground in a site such as a home.

The drainage pit installed in the gutter of the road or in the grounds of households is fitted with a lid with a through hole that closes the open end of the ground, so rainwater that falls on residential land or on the road passes through the lid. It is stored in the drainage basin through the hole, and drained from the drainage basin to a predetermined place through the drainage pipe. Further, waste water from the kitchen is stored in a drainage basin from a drainage pipe, and similarly drained from the drainage basin to a predetermined place through the drainage pipe. In the drainage basin having such a structure, rainwater flows into the drainage basin from the through hole of the lid that covers the ground opening of the drainage basin, while, for example, mosquitoes and their eggs invade the drainage basin through the through hole. A mosquito larva's bow flares in the pooled water in the cage springs up and causes mosquitoes to jump out of the through hole. Similarly, insects such as cockroaches generated in the drainage basin and puppies having a size of about 2 mm jump out of the through hole and propagate in the premises of the house, parks, etc., which is not preferable in terms of hygiene. Moreover, the bad smell of the accumulated water in which various wastewater and rainwater are accumulated in the drainage basin is released from the through-hole of the lid, causing deterioration of the environment.

Accordingly, various insect repellents for drainage traps have been proposed that prevent mosquitoes and the like from entering and exiting the ground through the through hole of the lid.

For example, as in Patent Document 1, the mosquito net is cut freely with a scissors or the like according to the shape of a rainwater jar (hereinafter referred to as a drainage jar) and laid on the entire surface of the lid receiving frame, or a deflection or gap on the back of the lid. Insect repellents for drainage jars that are bonded with double-sided adhesive tape or gummed tape have been proposed, and a net is attached to the bottom surface of the lid so as to cover the through-hole of the lid of the drainage basin as in Patent Document 2. Insect repellents for drainage traps have been proposed.

In addition, as in Patent Document 3, mosquitoes are prevented from being generated in a gutter in a drain gutter installed in a gutter of a road or on a site such as a home, and odor is released from the drain gutter. As a drainage basin capable of shielding the scattering, an inner lid made of an iron plate, stainless steel plate, aluminum, synthetic resin, FRP, etc. with an inclined piece inside the drainage basin is provided in a closed state by a spring force so as to be freely opened and closed. In the closed position of the lid, the rainwater that has entered the drainage basin from the drainage hole of the lid (corresponding to the through-hole of the lid) is blocked, and the rainwater exceeds a certain amount and resists spring force by a certain amount of gravity. The sloping piece can be opened to prevent mosquitoes from spawning in the water pool even if mosquitoes enter from the drain hole of the lid, preventing mosquitoes from being generated from the drainage basin, and leaking odors Insect repellents for drainage traps to prevent have been proposed.

However, in the proposal of the insect repellent for drainage jars such as Patent Document 1 and Patent Document 2, the function of discharging rainwater from which fallen leaves, earth and sand, etc. tend to stay on the mosquito net or net from the through hole of the lid is impaired. It is always necessary to clean the net of the mosquito net or the net, and there is a possibility that the adhesion between the net and the lid is peeled off. On the other hand, there is a problem that the bad odor of the accumulated water in the drainage basin passes through the mesh. In addition, the proposal of the insect repellent for drainage jars as in Patent Document 3 can reduce the scattering of odor from the drainage basin, but if rainwater increases, the inner lid is damaged by rainwater flowing back from the drainage pipe. In addition, there is a problem in that it requires a special closing means for damming rainwater, resulting in an expensive drainage insect repellent. In addition, since the structure is opened by a certain amount of gravity or more, a small amount of rainwater may accumulate and mosquitoes may breed.

The present invention has been made to solve such a problem, and a mosquito or the like is passed through a lid from a drain gutter installed in a gutter on a road or in a ground of a home with a simple configuration. It is an object to provide an insect repellent for a drainage basin that can be prevented from jumping out to the ground via a spillage or entering a drainage basin and further reducing the scattering of odors from the inside.
