Automatic drainage type sewage well lid preventing water accumulation

Abstract

The invention relates to the technical field of sewage, in particular to an automatic drainage type sewage well lid preventing water accumulation. The automatic drainage type sewage well lid preventing water accumulation comprises a pavement. The top of the pavement is fixedly connected with a well lid. The bottom of the well lid is provided with water discharging grooves distributed evenly. A water accumulation groove is formed in the middle of the well lid. The middle of the water accumulation groove is connected with a floating board which is movably connected with the inner wall of the well lid. The top of the floating board is fixedly connected with a moving rod which is movably connected with the middle of the well lid. A water inlet hole is formed in the middle of the moving rod. According to the automatic drainage type sewage well lid preventing water accumulation, by means of cooperative use of water linkage holes and the water discharging grooves, when rainwater is excessive,the rainwater enters the water accumulation groove through the water leakage holes and the water inlet hole, the floating plate can move upwards under the action of buoyancy of rainwater, the movingrod is moved upwards, sector fans are driven to be folded inwards, water drainage holes and the water discharging grooves are exposed, the water flow of the well lid is increased, and therefore the effect of facilitating drainage is achieved; and in this way, the rainwater discharge flow is increased, and rainwater accumulation is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to an automatic drainage type sewage manhole cover for preventing stagnant water. Background technique [0002] The sewage well cover is a kind of equipment used to seal the sewage wellhead. Sealing the sewage wellhead can effectively prevent the smell of sewage from spreading everywhere, and effectively prevent passing pedestrians or vehicles from falling into the sewage well to protect personal safety. [0003] The current manhole cover often encounters some problems during use. Because the manhole cover plays the role of sealing the wellhead, there are only two leakage holes in the manhole cover. Drainage, forming stagnant water, affecting road traffic, easily causing traffic jams and inconvenient travel, and when the stagnant water is too deep, traffic accidents are prone to occur, affecting personal safety. [0004] Therefore, we proposed an automatic drainage type sewage manho...
