Description

Automatic closed anti-overflow rainwater grate

Technical Field

The utility model belongs to the technical field of drainage engineering, and particularly relates to an automatic closed anti-overflow rainwater grate.

Background

With the rapid development of cities in recent years, urban waterlogging is increasingly serious, life and property safety of urban residents is seriously threatened every rainy season, and the occurrence of the waterlogging is a systematic problem, but a rainwater pipe network system plays a very important role. In a rainwater pipeline system, a rainwater inlet is a starting point of the whole rainwater drainage system, and the improvement of functions and the exertion of functions of the rainwater drainage system play an important role in the normal operation of the urban rainwater drainage system.

The design of the inlet for stom water mainly considers the rainfall runoff under the condition of certain reappearance period in its water receiving range, because the influence of its place environment in actual operation in-process, the inlet for stom water department often exists great difference with the design operating mode, for example urban living area road inlet for stom water can a large amount of large granule solids and other solid waste in the use, like fallen leaves, food and beverage discarded object etc. get into in the inlet for stom water through the inlet for stom water of rainwater grate, this will lead to following result:

1. resulting in a reduced or even complete blockage of the water-passing capacity of the rainwater pipeline system.

In rainy days, along with the increase of ground runoff, the inflow of the water inlet is gradually increased, local rainwater can be discharged in time under the normal operation condition, but when a rainwater pipeline is blocked by household garbage and other solid wastes, the flow cross section is reduced, the water flow resistance is increased, the local rainwater can not be discharged in time, and meanwhile, the upstream rainwater can overflow the ground through a rainwater grate, so that the local water accumulation is increased, and waterlogging loss is caused or aggravated.

2. Resulting in deterioration of water quality in the rainwater pipeline.

The solid waste entering the rainwater pipeline system through the rainwater grate water inlet holes is mostly in the categories of household garbage, dry branches, rotten leaves, road sprinklers and the like, the water quality in the rainwater pipeline can be polluted while the drainage capacity of the pipeline is reduced, and according to the research results of related research data, the pollution degree of initial rainwater sometimes exceeds the household sewage even, and serious pollution is caused to downstream receiving water bodies such as rivers, lakes or reservoirs.

3. Resulting in a significant increase in the operational maintenance effort and difficulty of the rainwater pipeline system.

In order to ensure the normal operation of urban pipeline systems in rainy seasons, municipal unit workers are often required to clean the rain water inlet and dredge urban pipelines in advance, but the open rain water inlet often enables the rain water pipeline systems to be solid garbage collection systems, so that the workload of workers and the cleaning difficulty are increased.

Therefore, how to prevent solid waste from entering a rainwater system and prevent rainwater from overflowing is important.

The existing gully is mainly divided into four types of flat grate type, offset ditch type, combined type and vertical grate type, and the common use is the flat grate type and the offset ditch type. The corresponding rain grate is mainly made of three materials, namely spheroidal graphite cast iron, a steel grating plate and a steel-plastic composite material. The rain grate is made of ductile iron, and the form of the rain grate can be divided into various different types, but the rain grate in any form has no functions of preventing solid waste from entering a rain system and preventing rainwater from overflowing back.
