[0004] The purpose of the present invention is to provide a bridge guardrail drainage and sewage system with environmental protection function to solve the following technical problems: (1) rainwater enters the sewer cavity of the guardrail column through the guide groove through the inflow hole, and the rainwater passes through the support along the sewer cavity The annular through hole on the plate enters the upper drainage cavity, the sewage and sludge on the bridge
deck enters the upper drainage cavity through the square hole on the support plate, and the sludge sewage passes through the upper plate, filter plate, and lower net through the guidance of the guide plate. The filter plate first filters the sludge and sewage, and the filtered sludge and sewage enter the filter chamber, and the second filter of the sludge and sewage passes through the filter core in turn through the upper leakage hole on the pressure plate and the filter on the barrier plate. The lower leakage hole enters the lower drainage chamber, and the second-filtered sludge and
suspended solids in the sewage are adsorbed on the filter plate and
filter element to obtain filtered water, which passes through the connecting holes at the bottom of the lower drainage chamber in turn 1. The water inlet hole on the water outlet chamber enters the water outlet chamber, the output shaft of the third motor drives the rotating rod to rotate, and the rotating rod drives the
spiral blade on the surface to rotate, and the
spiral blade discharges the filtered water from the drain hole. Through the above structure, the The guardrail column of the drainage and sewage system can also drain rainwater. At the same time, it cooperates with the square hole on the support plate to filter sewage and sludge. Through the design of the filter plate and
filter element, the sludge and sewage can be double-filtered. Well, the treated sludge and sewage can be directly discharged into the river after being filtered without causing
pollution. Through the design of the spiral blade, it is convenient to guide the filtered water out of the water outlet cavity, which solves the problem of drainage and sewage of bridge guardrails in the prior art. The system cannot filter the sewage and sludge on the bridge surface, and at the same time, it is prone to block technical problems during drainage and
sewage discharge; (2) Garbage enters the crushing trough of the garbage crushing chamber through the garbage inlet on the support plate, and the fourth motor The output shaft drives one of the driving rollers to rotate, and one of the driving rollers drives the other driving roller to rotate through the two gears connected by meshing. The two driving rollers rotate in opposite directions to crush the garbage. Pass through the first connection port and the second connection port to enter the garbage storage chamber, open the cover plate, and the crushed garbage can be taken out. With the above structure, only the cleaners need to sweep the garbage on the ground into the garbage inlet to complete the process The crushing of rubbish facilitates the centralized treatment of rubbish, and solves the technical problem that the rubbish on the bridge
deck in the prior art needs to be cleaned by cleaners in time and transported by garbage trucks. The cleaning of the rubbish on the bridge
deck is troublesome and difficult to carry out centralized treatment; (3 ) The output shaft of the first motor drives the filter plate to move out from the first drawing slot on the upper drainage chamber through the gear and the rack on the filter plate, and the output shaft of the second motor drives the drive rod to rotate, and the drive rod cooperates with the teeth on the barrier plate through the gear The bar drives the barrier plate to move out from the second pulling groove on the lower drainage cavity. Through the above structural settings, the filter plate and barrier plate of the drainage and sewage system are convenient to pull, which is convenient for the replacement of the filter plate in the system, and solves the problem in the prior art. The technical problem that it is difficult to replace the filter screen inside the drainage and sewage system of the bridge guardrail
