Abstract

A gutter inlet automatic overflow pollutant intercepting device comprises a clamping seat. At least one extensible rod is connected with the portion below the clamping seat. The lower end of the extensible rod is connected with a metal support. The metal support and the extensible rod are sleeved by a filter screen. The gutter inlet automatic overflow pollutant intercepting device is characterized in that the clamping seat comprises a grease absorbing cable clamping groove. According to the gutter inlet automatic overflow pollutant intercepting device, pollutants entering a gutter inlet is intercepted through the pollutant intercepting filter screen, so that the gutter inlet and a rainwater pipeline are prevented from being blocked, and the water discharging capacity of a rainwater pipeline network is improved; the pollutants are controlled from a source through the rainwater pipeline network, so that disposing pressure of a sewage disposal plant and pollution to city water by runoff pollution are reduced. Grease type pollutants in runoff rainwater can be effectively controlled through the arrangement of a grease absorbing cable, so that the following disposing cost of the sewage disposal plant and the pollution of city water are reduced, and the gutter inlet automatic overflow pollutant intercepting device has obvious environment and economic benefits. According to the gutter inlet automatic overflow pollutant intercepting device, the structure of an existing gutter inlet is not changed, the improving cost of the gutter inlet is reduced, and the gutter inlet automatic overflow pollutant intercepting device is simple in structure, practical and low in production cost.

Description

technical field

[0001] The invention relates to a sewage intercepting device, in particular to a sewage intercepting device for a rainwater outlet. Background technique

[0002] In recent years, urban waterlogging has occurred frequently in my country, and the design capacity of pipelines can generally cope with heavy rains that occur once in 1 to 3 years. Urban road sewage is usually collected into stormwater outlets (facilities that collect surface water in pipeline drainage systems, consisting of water inlet grates, shafts and Branch pipes, etc.) and then enter the urban sewage treatment system. However, the blockage of pipes and gullies caused by poor management and man-made pollution of gullies during dry periods reduces the drainage capacity of the pipe network, putting great pressure on urban drainage and affecting the safety of urban residents. In addition, the discharge of pollutants produced by the rainwater runoff washing away the garbage and pipeline sediments in...
