Road well lid for sewage treatment with self-adjusting water flow amount

Abstract

The invention discloses a road well lid for sewage treatment with self-adjusting water flow amount, and relates to the technical field of sewage treatment. The road well lid comprises a well lid, wherein the middle of the well lid is movably connected with a movable plate, the inner top wall of the movable plate is fixedly connected with a floating plate, a groove is formed in the middle of the movable plate, and water inlet holes which are uniformly distributed and extend into the middle of the groove are formed in the outer side of the movable plate. According to the road well lid for sewagetreatment with self-adjusting water flow amount, through cooperative use of the floating plate and the water inlet holes, in the initial state, the movable plate retracts into the well lid under theaction of a spring, and when the water quantity of a road is too large, the buoyancy of the floating plate drives the movable plate to move upwards, so that the rainwater on the road is discharged into the sewer through the water inlet holes on the outer side of the movable plate; and the larger the water quantity is, the larger the distance that the floating plate drives the movable plate to moveupwards is, the more part leaking out of the water inlet hole is, and the larger the water inlet amount is, so that the effect of self-adjusting the water inlet amount is achieved; and the corresponding adjustment is carried out according to the rain water amount, and the road accumulated water is effectively solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a road manhole cover for sewage treatment with self-adjusting flow rate. Background technique [0002] Road manhole covers are equipment often used in sewage treatment projects. Manhole covers are mainly installed at the exit of the sewer, which is convenient for rainwater drainage and also facilitates later inspection and maintenance. [0003] The following situations often occur during the use of the current manhole cover. Due to the constant water flow of the current manhole cover, when there is too much rain on the road, it is easy to cause water accumulation on the road, it is difficult to see the road condition, there are too many safety hazards, and when there is too much water, The manhole cover is easy to shift under the action of water flow, resulting in the exposure of the pipe opening, which poses a safety hazard. [0004] Therefore, we proposed a road manho...
