AI Technical Summary

Technical Problem

Untreated runoff from bridge decks is discharged directly into the receiving water bodies, causing pollution. Furthermore, the inlets of existing pollution control equipment are prone to clogging, affecting the normal operation of the equipment and reducing its service life.

Method used

A bridge deck runoff pollution control device was designed, comprising components such as a bridge, drainage ditch, bar screen, inlet pipe, main pipe, control box, filter screen, motor, cleaning brush, rotating ring, rotating plate and stirring rod. It treats bridge deck runoff through filtration, stirring and branching to avoid blockage and extend the service life of the equipment.

Benefits of technology

It effectively filters large impurities in bridge runoff, reduces inlet blockage, extends equipment lifespan, and ensures normal operation of pollution control equipment and safe water discharge.

Abstract

The utility model discloses a bridge deck runoff pollution prevention and control equipment, including bridge, the left and right upper surface of bridge is opened with the drainage groove symmetry, the upper surface of drainage groove is overlapped and has the grating, the lower surface fixedly connected with the water inlet pipe of drainage groove, the lower surface fixedly connected with the main pipeline of water inlet pipe. This bridge deck runoff pollution prevention and control equipment, through the setting of bridge, drainage groove, grating, water inlet pipe, main pipeline, prevention and control box, water inlet, filter screen, motor, mounting panel and cleaning brush, the rainwater or dangerous leakage article of bridge upper portion is filtered after the big impurity garbage of grating and enters the drainage groove, then through the water inlet of water inlet pipe and is gathered into main pipeline and carries out the pollution prevention and control detection of prevention and control box, and the filter screen carries out the filtration again, and the cleaning brush on the mounting panel is driven to rotate and clean the filter screen under the drive of motor, reduces the blockage rate of water inlet, avoids because of the normal operation of prevention and control box because of the blockage, prolongs the service life of equipment.
