Automatic anti-precipitation drainage device for municipal bridge

Abstract

The invention provides an automatic anti-precipitation drainage device for municipal bridges, and belongs to the technical field of municipal bridges. The device comprises a transfer pool, a drainagepipe is connected to the transfer pool, an on-off valve is arranged on the drainage pipe, a selector switch assembly is connected to the on-off valve, a sealing chamber is arranged on the outer side wall of the transfer pool, and a piston is slidably connected to the left side of the sealing chamber. A driving rod is fixedly connected to the left side of the piston, a connecting rod driving seat assembly is connected to the bottom surface of the transfer pool, a push plate is fixedly connected to the connecting rod driving seat assembly, and an air bag is connected to the push plate. Accordingto the automatic anti-precipitation drainage device for the municipal bridge, the transfer pool drives the change-over switch assembly to control the on-off valve through the connecting rod driving seat assembly, so that the situation that the drainage effect is affected due to the fact that garbage accumulates, precipitates and is adsorbed to the inner wall of the drainage pipe due to the fact that the speed of water flowing through the drainage pipe is low is effectively avoided, the quality of the municipal bridge and the safe passing of the bridge are guaranteed, and meanwhile, the maintenance cost of municipal bridges is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal bridges, in particular to an automatic anti-sedimentation drainage device for municipal bridges. Background technique [0002] The municipal bridge is one of the very important projects in the construction of the entire municipal road, and the drainage device in the municipal bridge is an important factor affecting the quality of the municipal bridge deck and ensuring safe passage. The drainage device of the municipal bridge is mainly to drain rainwater , to prevent water accumulation on the bridge deck, affecting the normal and safe passage of passing vehicles, and at the same time prevent rainwater from accumulating on the bridge deck for a long time, which will adversely affect the quality of the bridge deck. [0003] In daily use, due to the difference in the amount of rainwater, when the drainage device discharges rainwater through the drainpipe, the waste will accumulate and precipitate on...

[0002] The municipal bridge is one of the very important projects in the construction of the entire municipal road, and the drainage device in the municipal bridge is an important factor affecting the quality of the municipal bridge deck and ensuring safe passage. The drainage device of the municipal bridge is mainly to drain rainwater , prevent water accumulation on the bridge deck, affecting the normal and safe passage of passing vehicles, and prevent rainwater from accumulating on the bridge deck for a long time, causing adverse effects on the quality of the bridge deck

[0003] In daily use, due to the difference in the amount of rainwater, when the drainage device discharges rainwater through the drainpipe, the waste will accumulate and precipitate on the drainpipe due to the slow flow rate of the water, which will affect the quality of the drainagepipe. The drainage effect will affect the quality of municipal bridges and the safety of traffic, and once the garbage is accumulated on the inner wall of the drain pipe, it is very difficult to clean the drain pipe, thereby increasing the maintenance cost of municipal bridges
