Manhole cover

Abstract

The invention provides a manhole cover, and relates to the field of intelligent manhole covers. The manhole cover comprises a mounting ring, a manhole cover, a buffering section and a water passing opening, wherein the water passing opening is round and is formed in the outer wall of one end of the manhole cover, the mounting ring is matched with the manhole cover, the buffering section is arranged between the mounting ring and the manhole cover, the manhole cover is composed of an upper end and a lower end which are movably connected, a buffering rod is arranged between the upper end and the lower end of the manhole cover, a mounting cavity is reserved in the inner wall of the manhole cover, a buffering air bag is arranged on the inner wall of the mounting cavity, a protection plate is arranged on the outer wall of the bottom end of the manhole cover, and a positioning controller is arranged on the inner wall of the protection plate. According to the manhole cover, a clamping block can be sucked from the interior of a fixed clamping block by an electromagnet for further clamping, so that the manhole cover is difficult to take out, the manhole cover has an anti-theft function, and when the manhole cover needs to be recycled, the electromagnet can be started to generate a magnetic force in the opposite direction so as to push out the fixed clamping block, so that the manhole cover can be quickly recycled.

Description

technical field [0001] The invention relates to the technical field of intelligent manhole covers, in particular to a manhole cover. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. Manhole covers can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers according to their materials. Usually round. It can be used in green belts, sidewalks, motorways, docks, alleys, etc. [0003] In the use of manhole covers, because they are easy to lose, they will not only cause losses to public property, but also pose potential safety hazards. At the same time, when the manhole covers are in use, cars will also make a lot of noise when passing by, which will have a negative impact on pedestrians around the road. The water outlet is also easily blocked by impurities such as fallen leaves, which affects the water passage effect. Contents of t...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a manhole cover, which solves the problem that in the use of the manhole cover, it will not only cause loss to public property due to easy loss, but also have potential safety hazards. At the same time, when the manhole cover is in use, cars will It produces a lot of noise, which has a negative impact on pedestrians around the road. The water outlet of the manhole cover is also easily blocked by impurities such as fallen leaves, which affects the water flow effect.
