A drainage device for a bridge

Abstract

The invention relates to the field of bridge equipment, in particular to a drainage device for a bridge. The drainage device for the bridge comprises a processing box, a sewage collection box, a filter mechanism and an oil removal mechanism. The processing box is internally provided with a filter cavity, an oil absorption cavity and an oil collection cavity, the filter mechanism and the oil removal mechanism are correspondingly installed in the filter cavity and the oil absorption cavity, and the sewage collection box is positioned at one side of the processing box; a water inlet pipe is arranged at the upper end of the processing box, an oil drain pipe and a water drain pipe are arranged at the lower end of the processing box, and an oil collection pipe communicating with the oil drain pipe is arranged at the lower end of the oil drain pipe; a material outlet is formed in one side of the processing box, and a material blocking assembly is arranged at the material outlet; and the filter mechanism comprises a filter screen and a swinging assembly, a hinged shaft is arranged at one end of the filter screen, and the filter screen is hinged to the processing box through the hinged shaft. The drainage device for the bridge has the beneficial effects of being capable of discharging oil stains and sand and gravel in drainage, avoiding pipeline blockage, and being simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of bridge equipment, in particular to a drainage device for bridges. Background technique [0002] If there is too much water on the bridge, it will easily reduce the friction between the tires and the bridge deck, which will cause the wheels to slip and easily lead to traffic accidents. Therefore, the role of the bridge drainage system is particularly important, but the bridge deck is full of gravel, and There are also other garbage, which can easily cause pipe blockage under the alluvial rainwater. [0003] Chinese Patent No. CN105862585B has announced a bridge deck sewage treatment device, including a water collection channel, which is characterized in that the water collection channel is connected to a separation box, and a water filter plate is arranged in the separation box, and the bottom of the water filter plate is arranged There is a water collecting tank, and the spoke rotor driven by the motor is installe...

[0002] If there is too much water on the bridge, it will easily reduce the friction between the tires and the bridge deck, which will cause the wheels to slip and easily lead to traffic accidents. Therefore, the role of the bridge drainage system is particularly important, but the bridge deck is full of gravel, and There are other garbage, which can easily cause pipe blockage under the rainwater alluvial

[0003] Chinese Patent No. CN105862585B has announced a bridge deck sewage treatment device, including a water collection channel, which is characterized in that the water collection channel is connected to a separation box, and a water filter plate is arranged in the separation box, and the bottom of the water filter plate is arranged There is a water collecting tank, and the spoke rotor driven by the motor is installed above the water filter plate; the discharge port of the spoke rotor is equipped with a conveyor belt driven by a conveyor belt motor, and the discharge end of the conveyor belt is installed with a garbage outlet stop; A cold air blowing pipe is connected above the conveyor belt in the separation box; this patent is mainly used to purify sewage, but the bridge deck area is not large, and multiple sewage treatment devices should be installed along the length of the bridge body, which makes each sewage treatment device treat The amount of sewage is small, and the rainy and snowy weather is not fixed, and the sewage treatment device is used less frequently. However, the invention has a complex structure and more equipment, which makes its cost higher and corresponds to a lower utilization rate, which is serious. It leads to economic waste, and secondly, the follow-up treatment of solid impurities in the device is inconvenient

This patent has similar problems with the above-mentioned patents. The complex structure and many equipments lead to high cost, and the maintenance is inconvenient. Its cost cannot match its utilization rate.
