Drainage filtering device for adjusting drainage port along with rainfall

Abstract

The invention discloses a drainage filtering device for adjusting a drainage port along with rainfall. The device comprises a box body, a detection cavity with an upward opening is formed in the box body, three filtering cavities with upward openings are formed in the box body, and a drainage mechanism used for controlling opening and closing of a drainage hole is arranged in the box body. A telescopic plate with a built-in spring is fixedly connected to the rear inner wall of each filtering cavity, a compression cavity with a forward opening and a moving cavity are formed in the rear inner wall of each filtering cavity, and a moving plate is slidably connected into each moving cavity. The device is simple in structure, convenient to use and capable of adjusting the size of the drainage port according to rainfall, the situation that road surface water accumulation is caused by unsmooth drainage when the rainfall is large, and normal running of vehicles is affected is prevented, besides, rainwater can be filtered, and road surface sundries are prevented from blocking a sewer. The device can be sealed at ordinary times and can prevent the road environment from being influenced by sewer odor return.

Description

technical field [0001] The invention relates to the field of drainage equipment, in particular to a drainage filtering device for adjusting a drainage outlet according to rainfall. Background technique [0002] Today's road drainage facilities are relatively rigid and old, and the drainage outlets cannot be adjusted automatically. Therefore, when the rainfall is frequent or the precipitation is too large, there will often be water on the road. The water on the road will affect the normal driving of vehicles on the road. It will cause the vehicle to slip on the liquid surface, which is extremely unfavorable to traffic safety, and more water will also affect the normal travel of pedestrians; [0003] In addition, when the weather is relatively hot, the sewers often emit odors, which affect the environment of the road. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a drainage filtering device that adjusts the drai...
