Odor-proof and overflow-proof floor drains for urban pavement drainage

Abstract

The invention belongs to the technical field of municipal drainage facilities, and particularly relates to an odor-resistant overflow-resistant floor drain for city pavement drainage. The odor-resistant overflow-resistant floor drain comprises a cylindrical bracket, a cover plate, a first water baffle plate and a second water baffle plate, wherein the second water baffle plate is arranged in a reciprocation movement manner in a vertical direction; when the first water baffle plate is clung to the second water baffle plate, respective hollow parts can be covered by each other to form a waterproof sealed baffle layer; an elastic unit is arranged between the second water baffle plate and the cylindrical bracket; the elastic unit can provide an upward elastic force to the second water baffle plate. As the internal space of a sewer is baffled through the baffle layer formed by the first water baffle plate and the second water baffle plate, and the second water baffle plate and the first water baffle plate are closed under a condition of sunny climate, waste gases inside the sewer can be prevented from overflowing; under a condition of stormy and rainy climate, the second water baffle plate can be opened under the action of gravity of rainwater, then normal drainage can be achieved; under a condition of heavy rain, when sewage inside the sewer flows upwards, the sewage can be effectively prevented from overflowing by the second water baffle plate.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage facilities, and in particular relates to an odor-proof and overflow-proof floor drain used for urban road surface drainage. Background technique [0002] There are two main problems in traditional municipal drainage facilities: one is that the waste gas produced by underground sewage will overflow from the outlet, causing damage to the surrounding environment, and the toxic gas in it will even cause harm to the human body; the other is that under heavy rain conditions, a certain There will be a large amount of sewage gushing out of the drains in some low-lying areas, which will cause the water level in the low-lying areas to rise rapidly and affect the normal walking of the road. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide an odor-proof and overflow-proof floor drain for urban road drainage. [0004] In o...
