Sewer cover with overturn blocking pieces

Abstract

A sewer cover with overturn blocking pieces comprises a cover body provided with barrier holes. Bases are arranged on the two sides of the cover body, the cover body can move vertically in the bases, and perpendicular reset springs are arranged between the cover body and the lower edges of the bases. The overturn blocking pieces corresponding to the barrier holes are arranged on the lower side of the cover body, one end of each overturn blocking piece is connected to an overturn shaft, the two ends of each overturn shaft are erected on fixing blocks arranged on the lower edges of the bases, and gears are fixed to the two ends of each overturn shaft. Protruding blocks are arranged on the lower surface of the cover body, and a rack meshed with the gears is arranged on one sides of the protruding blocks. The protruding blocks are driven to move downwards when the cover body moves downwards, the gears are made to rotate, and thus the overturn blocking pieces can block the lower sides of the barrier holes after being overturned. When pedestrians walk, the barrier holes, under the feet of pedestrians, of the sewer cover can be automatically closed, and thus small objects are prevented from being accidentally dropped into a sewer; in addition, after pedestrians walk past the sewer cover, the barrier holes can be automatically opened, and normal drainage is not affected.

Description

technical field [0001] The invention belongs to the field of municipal supplies, and in particular relates to a sewer cover with a turn-over baffle. Background technique [0002] With the acceleration of urbanization, urban infrastructure construction has attracted more and more attention from citizens, and some humanized details in municipal construction have also become more and more popular among citizens. [0003] At present, a lot of road both sides are also provided with the sewers that are used for rainwater, sewage discharge, and these sewers are covered with the sewer covers of fence type, and rainwater can enter in the sewers through the fence through holes when it rains, and is used for road drainage. However, this type of sewer cover often causes items to fall into the sewer. For example, when pedestrians walk on the side of the road, when items such as mobile phones, keys, and wallets fall from their hands, they pass through the fence hole and enter the sewer. ...

Problems solved by technology

However, this type of sewer cover often has items falling into the sewer. For example, when pedestrians walk on the side of the road, when items such as mobile phones, keys, and wallets fall from their hands, they enter the sewer through the fence hole. It is often necessary to lift the sewer cover to take out the items. Once there is water in the sewer, it will also cause damage to the mobile phone, which is very troublesome
