Small-pollution and low-cost inverted siphon desilting device and method free of water interruption

Abstract

The invention discloses a small-pollution and low-cost inverted siphon desilting device free of water interruption. The small-pollution and low-cost inverted siphon desilting device free of water interruption comprises a silt removal cabin, a silt suction pump and a cable. A silt delivery pipe is connected with one side end of the silt removal cabin. A silt removal cabin traction rope is connected with the two side ends of the silt removal cabin. The silt removal cabin comprises silt removal cutters, a cutter rest beam, cutter rest guide rails and a silt removal cabin body. The cutter rest guide rails are arranged on the upper portions of the two sides in the silt removal cabin body, the cutter rest beam is located on the cutter rest guide rails, the silt removal cutters are installed on the cutter rest beam, and each silt removal cutter comprises a rotating cutter head, a transmission shaft, a motor and a communicating pipe. A cutter rest traction rope is connected to the two ends of the cutter rest beam. A silt removal cabin lower probing part is arranged at the lower end of the silt removal cabin. Communicating holes are formed in the upper end of the silt removal cabin. A fairing is installed outside the silt removal cabin. The small-pollution and low-cost inverted siphon desilting device free of water interruption has the advantages of being small in water body pollution, free of water interruption for evacuation and low in cost. The invention further discloses a small-pollution and low-cost inverted siphon desilting method free of water interruption.

Description

technical field [0001] The invention relates to the field of inverted siphon dredging, in particular to a low-cost, less-polluted inverted siphon dredging device without interruption of water supply. The invention also relates to a small-pollution and low-cost inverted siphon dredging method without interrupting water flow. Background technique [0002] Inverted siphons are pressure pipes that transport rivers and channels through rivers, valleys, depressions, and roads. Both ends of river inverted siphons are connected to natural rivers. Sediment will continue to accumulate in the inverted siphon and even block the pipe body; Under the condition of less than the designed water delivery flow, sediment deposition will also occur; the deposition in the siphon will seriously affect its flow, and cause damage to flood control and water supply capabilities.

AI Technical Summary

Problems solved by technology

[0002] Inverted siphons are pressure pipes that transport rivers and channels through rivers, valleys, depressions, and roads. Both ends of river inverted siphons are connected to natural rivers. Sediment will continue to accumulate in the inverted siphon and even block the pipe body; Under the condition of less than the designed water delivery flow, sediment deposition will also occur; the deposition in the siphon will seriously affect its flow, and cause damage to flood control and water supply capacity

[0003] The inverted siphon is a pressurized water delivery pipe, and the sedimentation shell formed on the lower surface of the pipe body is relatively hard. It is difficult to achieve the desired effect by hydraulic flushing, and mechanical dredging must be used; the river inverted siphon is connected to the natural river water body, and it is difficult to artificially control the water stop and emptying; As a water delivery and water supply facility, the inverted siphon will affect the normal operation of the entire water delivery and supply line once it is stopped.

[0004] Regarding the related issues in the field of inverted siphon dredging, no domestic related patents or molding technologies have been found
