Description
Technical Field
The invention belongs to the field of sewage treatment, and particularly relates to a self-adjusting bridge easy to drain.
Background
The existing bridge has two pollution discharge modes, one is that sewage on the bridge floor is directly discharged into river water from two sides of a bridge body, and is called direct drainage, and the other is that a pollution discharge channel is arranged on the bridge floor and is communicated with underground pollution discharge pipes on two sides of a river bank, and the sewage is collected into the pollution discharge channel and then enters an underground pipeline.
If the mode of direct drainage is adopted, sludge sundries on the bridge floor flow into rivers along with water, the rivers are easily polluted and difficult to clean, and the mode of discharging the water channels to the two sides of the river bank is adopted, so that the water discharging efficiency is limited, if strong rainfall seasons occur, a large amount of rainwater blocks up and overflows the water discharging channels, the bridge floor accumulates a large amount of rainwater and cannot be discharged in time, and the normal passing of vehicles and pedestrians on the bridge is influenced.
Therefore, a self-adjusting easy-drainage bridge is provided to solve the problems.
Disclosure of Invention
The invention aims to provide a self-adjusting easy-drainage bridge capable of automatically switching drainage modes, aiming at the problem that the drainage mode of a bridge deck is single and difficult.
In order to achieve the purpose, the invention adopts the following technical scheme: a self-adjusting easy-drainage bridge comprises a bridge body and drainage channels arranged on two sides of the bridge body, water outlets at two ends of the drainage channels are all arranged to extend to two ends of the bridge body, a plurality of straight drainage pipes extending to two sides of the bridge body are further arranged on the bridge body and communicated with the drainage channels, a containing cavity is arranged at the bottom of the drainage channels, a transparent daylighting plate is arranged on an upper end cover of the containing cavity, a lifting plate horizontally arranged is arranged in the containing cavity in a sealing and sliding mode, the lifting plate is made of transparent materials, an expansion agent is filled in a sealing space formed by the lower portion of the lifting plate and the containing cavity, a threaded rod is vertically arranged in the containing cavity, the upper end of the threaded rod sequentially penetrates through the lifting plate and the transparent daylighting plate and extends into the drainage channels, a splitter plate is arranged at the communication position of the drainage channels and the straight drainage pipes and fixedly connected with the threaded rod, and a threaded barrel is embedded in the lifting plate, the threaded barrel is sleeved outside the threaded rod and is in threaded fit with the threaded rod.
The invention has the advantages that:
at the early stage of heavy rainfall, accumulated water on the bridge floor is less, dust and sundries are more, water flow carries the dust and sundries to enter the drainage channel, the sewage is relatively turbid at the moment, the light transmittance is relatively low, external light is difficult to irradiate into the accommodating cavity through the turbid sewage, then gas in the expanding agent reacts to generate solids, the lifting plate is driven to move downwards under the action of air pressure, then the threaded rod is driven to rotate through the threaded barrel, the splitter plate is rotated to the communication position of the direct drainage pipe and the drainage channel, the pipe orifice of the direct drainage pipe is plugged, at the moment, less rainwater carries the sludge sundries to be discharged to two ends of the bridge body through the drainage channel, the river is prevented from being polluted by the sewage, and the rainwater cannot overflow to the bridge floor to influence traffic;
later stage in the heavy rainfall, the rainfall is great, rainwater on the bridge floor is more, and the dust debris of bridge floor has been washed away by the rivers at the rainfall initial stage this moment, then rainwater this moment is comparatively limpid, the luminousness is stronger, the clear sewage of external light accessible shines into holding the intracavity, then the inflation agent is by solid-state decomposition reaction process gas under the catalytic action of crossing light this moment, the air pressure is under the effect and is pushed the lifter plate rebound, then drive the nozzle that the flow distribution plate rotates and leaves the straight drainage pipe, and will drain the canal shutoff, then rivers can be directly discharged to the river by straight drainage pipe this moment, drainage speed promotes greatly, the pollution to the river has been reduced, the inefficiency of drainage has effectively been solved simultaneously, the problem that the rainwater overflow influences the traffic, the drainage mode is nimble.
Preferably, the area of the flow distribution plate is larger than that of the pipe orifice of the straight drainage pipe, so that sewage is prevented from being directly discharged into a river.
Preferably, the maximum included angle that the flow distribution plate can form with the lateral wall of the drainage channel is 45 degrees, is favorable to the guide of rainwater to dredge and flows for the rate of drainage of rainwater, the flow distribution plate is made by elasticity deformable material, and the flow distribution plate can be deformed under the impact of rivers, has further promoted its drainage rate.
