Sewer well lid capable of rising

Abstract

The invention relates to a sewer well lid capable of rising. The sewer well lid capable of rising is composed of a well lid body (1), a floater (8) and a connecting rod (7) connected between the welllid body (1) and the floater (8); guiding devices (3) are movably connected to the edge of the bottom of the well lid body (1) and connected through a ring (4); and the floater (8) is made of a floating material, when the sewer water level rises, the floater (8) rises through the buoyancy force to enable the well lid body (1) to rise, a certain clearance is formed between the well lid body (1) anda pavement, accumulated water can flow into a sewer through the clearance, and when the sewer water level falls, the guiding devices (3) guide the well lid body (1) to fall to the original position.When the sewer well lid capable of rising is adopted as a well lid on a road, the problem that water cannot be drained due to the fact that well lid water leaking holes are blocked by garbage can be effectively solved, and the well lid cannot be washed away by water and is very safe.

Description

technical field [0001] The invention belongs to the field of sewer engineering, and more specifically relates to a riseable sewer manhole cover. Background technique [0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers and resin manhole covers. They are generally round and can be used for green belts, sidewalks, motor vehicles Driveways, piers and alleys, etc., have the characteristics of high strength, beautiful appearance, convenient use, light weight, acid and alkali resistance, corrosion resistance, wear resistance, vehicle rolling resistance and long service life. [0003] Sewer manhole covers can often be seen on the road or in the green belt. The material of the existing sewer manhole covers is generally made of steel or concrete. Leakage holes are set on the covers. This kind of manhol...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem of water accumulation on the road and the well cover being washed away by water caused by garbage blocking the leaking holes in the prior art, and to provide a riseable sewer manhole cover, which can not only rise according to the rise of the sewer water level, but also according to the Falls back to its original position when the water level drops and prevents the flow of water from washing away the manhole cover
