A manhole cover with automatic switch

Abstract

The invention discloses an inspection well cover with the automatic opening-closing function and relates to an inspection well cover. Currently, the water leakage portions of city inspection well ditch cover plates are normally open, and consequently a larger amount of garbage enters a sewer and pollutes a river. The inspection well cover with the automatic opening-closing function comprises a cover plate, a drum opening-closing plate, a tension spring, a drum opening-closing plate control device, wherein the drum opening-closing plate control device comprises a water collecting trough provided with a draining opening, a pulling rope, a balance weight floating ball connected with the lower end of the pulling rope and a rotary shaft disposed on the lower end face of the cover plate; one endof the tension spring is connected with the lower end face of the cover plate, the other end of the tension spring is connected with the drum opening-closing plate, the pulling rope penetrates through a gap between the cover plate and the rotary shaft, and the balance weight floating ball at the lower end of the pulling rope is arranged in the water collecting trough in a suspending mode; the drum opening-closing plate comprises a plurality of drums which are distributed side by side and connecting parts used for being connected with the adjacent drums, and the drums are parallel to a water passing trough; and the distance between the adjacent drums is matched with the distance between the cover plate and the water passing trough. According to the technical scheme, the drum opening-closing plate is arranged, the bottom of the water passing trough is sealed when no rainwater falls, and therefore the garbage is prevented from entering the sewer.

Description

technical field [0001] The invention relates to a manhole cover, in particular to a manhole cover with an automatic switch. Background technique [0002] At present, the leaky part of the manhole gutter cover plate in the city is always open, so that when it is not raining, a large amount of rubbish enters the sewer and pollutes the river course. And it is easy to block; for the well cover that can be opened and closed, the foreign matter embedded in the well cover will still fall in the well cover when it is opened, and the foreign matter cannot be completely blocked from entering. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a manhole cover with automatic opening and closing, so as to achieve the purpose of closing the manhole cover and avoiding the entry of sundries. For this reason, the present invention takes th...
