Abstract
The utility model provides an inspection well cover which can prevent poisonous and smelly air and mosquitoes in an inspection well from coming out. The inspection well cover is characterized in that a water inlet channel and a water outlet channel are arranged in a cover plate, and the water inlet channel and the water outlet channel are connected through a water holding channel which can hold water, and the water inlet channel and the water outlet channel can be separated by held water in the water holding channel.
Description
Technical field
The utility model relates to a kind of inspection well cover.
Background technology
At present, the inlet opening on the inspection well cover is a clear opening.When raining, rainwater enters in the inspection shaft by clear opening.But poisonous in mosquito and the inspection shaft has flavor gas can pass clear opening out.
Summary of the invention
The purpose of this utility model provides and a kind ofly can prevent that poisonous in the inspection shaft from having flavor gas and mosquito inspection well cover out.
This inspection well cover has intake tunnel and exhalant canal in cover plate, between intake tunnel and the exhalant canal by one can water the water passage link to each other; Intake tunnel and exhalant canal can be isolated by the water in the water passage.Best, the water passage becomes high, the middle low u shape in both sides.
The beneficial effects of the utility model: because the water of water passage, so that intake tunnel and exhalant canal are isolated; Poisonous in the inspection shaft has flavor gas and mosquito not to enter into intake tunnel from exhalant canal, so poisonous in the inspection shaft has flavor gas and the mosquito can not be in the inspection shaft out.
Description of drawings
Fig. 1 is the schematic diagram of inspection well cover.
The specific embodiment
Referring to inspection well cover shown in Figure 1, in cover plate 1, have intake tunnel 2 and exhalant canal 3, between intake tunnel and the exhalant canal by one can water water passage 4 link to each other; Intake tunnel and exhalant canal can be isolated by the water in the water passage.Intake tunnel 2, exhalant canal 3 and water passage 4 have formed S type elbow water sealing system.Next interim when rainwater, rainwater is in S type elbow water sealing system flows into inspection shaft.After the rainwater, can stockpile a certain amount of water in the S type elbow water sealing system (water passage 4), play the up and down effect that completely cuts off of space of inspection well cover, rainwater is leaked down, and pernicious gas can not be out in the same old way, mosquito can not freely be come in and gone out.
