Description

Technical Field

[0001] This utility model relates to the field of municipal engineering facilities technology, specifically to an inverted siphon device for water conveyance pipelines that can automatically flush and remove sludge. Background Technology

[0002] When water pipelines cross obstacles such as rivers and ditches, an inverted siphon design is often used. This design involves burying the pipeline below the riverbed, forming a structure resembling an inverted siphon. The purpose of this design is to allow water to flow smoothly across the river while minimizing or avoiding impact and erosion on the pipeline. An inverted siphon system includes an inlet valve well, a downpipe, a parallel pipe, an uppipe, and an outlet valve well. During operation, silt inevitably accumulates within the pipeline. To facilitate dredging, a sludge discharge branch pipe is often extended from the lowest point of the parallel pipe to the riverbank, and sludge discharge valve wells and wet sludge discharge wells are installed. The bottoms of these sludge discharge valve wells and wet sludge discharge wells are generally below the riverbed scour line, resulting in significant burial depths, difficult construction, and high costs. Inverted siphon dredging often relies on timed dredging, making it impossible to accurately monitor the siltation status and the effectiveness of dredging uncertain. Furthermore, dredging requires manual opening of the sludge discharge valves, which is time-consuming and labor-intensive. Utility Model Content

[0040] To facilitate understanding of the present invention, the implementation process of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] This utility model relates to a water pipeline inverted siphon device. Under normal operating conditions, the inlet valve in the inlet valve well and the outlet valve in the outlet valve well remain open. Water flows through the downpipe, parallel pipe, and uppipe, passing through obstacles such as rivers and valleys in an inverted siphon manner. After a period of operation, impurities carried by the water flow will be deposited at the bottom of the parallel pipe and sludge hopper under the action of gravity. The sludge monitor and sludge detection pipe can monitor the sludge thickness in the sludge hopper in real time. When the sludge thickness reaches a certain level, the air compressor device is activated, the air flushing valve and sludge discharge valve are opened, and compressed air enters the air flushing pipe and then enters through the oblique tee. In the parallel pipe, the oblique entry of gas flushes the sludge deposited at the bottom of the pipe into the sludge hopper, preventing further deposition. Compressed air then enters the dosing ring through a positive tee, and from there, it evenly enters the sludge hopper and the ascending pipe through the air outlet on the dosing ring. This generates numerous tiny air bubbles in the sludge hopper and ascending pipe. These bubbles, upon contact with the sludge, adhere to its surface, forming bubble clusters. Under the influence of buoyancy and water flow, these bubble clusters travel along the ascending pipe into the outlet pipe, then through the sludge discharge valve into the sludge discharge branch pipe, and finally into the sludge discharge wet well with the water flow, before being discharged out of the system through the sludge discharge pipe. To prevent gas from entering subsequent pipes or flowing backwards into the inlet pipe, creating air resistance and increasing head loss, inlet and outlet air vent valves are installed in the inlet and outlet valve wells respectively to promptly discharge the flushing and sludge-discharging gas out of the pipes. The manhole cover and inspection steps facilitate the maintenance and replacement of air compressors, various valves, pipelines, and sludge monitors.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
