Emergency anti-flood drainage well lid

Abstract

The invention discloses an emergency anti-flood drainage well lid. The emergency anti-flood drainage well lid comprises a main body; a drainage cavity is formed in the main body; six rotating cover plates are mounted in the drainage cavity in an annular array mode; two drainage holes are formed in the rotating cover plates; the drainage holes can be used for daily drainage; extension devices are arranged in the rotating cover plates; and the extension devices comprise extension shafts inside. The daily drainage work can be performed through the drainage holes on the rotating cover plates; solid garbage in sewage is filtered and separated through a filter vibration device; the separated garbage is collected through a filter cavity to prevent blockage of a drainage cavity and to accelerate circulation of the sewage; secondly, the rotating cover plates can be rotated to drive stretching of the extension shafts, so that the water inlet quantity of the drainage cavity is increased, and thedischarge quantity of the sewage is increased; and the emergency anti-flood drainage well lid can be used for the anti-flood work, and guarantees the pedestrian or vehicle passing safety.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to an emergency flood control and drainage manhole cover. Background technique [0002] The traditional manhole cover drains water through the gap between the mesh plates, and its drainage is fixed. When the rainfall increases, the drainage hole displacement cannot be increased according to the actual situation, resulting in a small water discharge per unit time, and rainwater or sewage overflows. Secondly, the existing drainage manhole cover If the garbage filtering function is not installed in the device, solid waste such as leaves, plastic bags, and branches in the sewage or discharge water will block the drainage well cover and reduce the drainage speed. In addition, during flood control work, in order to increase the drainage, the well cover will be lifted. Then the well cavity is exposed outside, without protective measures, the safety protection of passing vehicles or ...

[0002] The traditional manhole cover drains water through the gap between the mesh plates, and its displacement is fixed. When the rainfall increases, the drainage hole displacement cannot be increased according to the actual situation, resulting in a small water discharge per unit time, and rainwater or sewage overflows. Secondly, the existing drainage manhole cover If the garbage filtering function is not installed in the device, solid waste such as leaves, plastic bags, and branches in the sewage or discharge water will block the drainage well cover and reduce the drainage speed. In addition, during flood control work, in order to increase the drainage, the well cover will be uncovered. If the well cavity is exposed and no protective measures are installed, the safety protection of passing vehicles or pedestrians will be low.
