An easy-to-drain manhole cover

Abstract

The invention provides an inspection well cover for easy drainage, which belongs to the field of inspection well covers. The utility model solves the problem that the existing manhole cover can only be opened as a whole to drain water. The easy drainage manhole cover includes a manhole cover and a cast iron seat matched with the manhole cover. The cast iron seat has an annular seat ring, and several support rods are connected between the circumferential direction of the manhole cover and the inner periphery of the seat ring. The cover is hinged, the other end of the support rod is hinged to the seat ring through the second rotating shaft, and the seat ring is provided with a receiving groove, and the wall of the receiving groove is provided with a chute. When on the seat, the rotating shaft 2 slides along the chute and the supporting rod is placed in the receiving groove. At this time, the manhole cover is flush with the upper surface of the seat ring, and one end of the supporting rod can be rotated along the rotating shaft, and the other end of the supporting rod is Rotate the rotating shaft 2, and make the rotating shaft 2 slide in the chute, and raise the manhole cover. During drainage and flood discharge, the manhole cover is raised through the support rod, and the gap between the manhole cover and the cast iron seat can be used to drain water.

Description

technical field [0001] The invention belongs to the technical field of inspection well covers and relates to an easy-drainage inspection well cover. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Called the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. [0003] However, with the continuous increase of urban construction, when the city is full of heavy rains, the inspection shaft cover will be opened for flood discharge, but only the entire ins...

Problems solved by technology

[0003] However, with the continuous increase of urban construction, when the city is full of heavy rains, the inspection shaft cover will be opened for flood discharge, but only the entire inspection shaft cover can be opened during the flood discharge process, making the position of the original inspection shaft cover very prone to danger.
