Novel green dredging device for lined open canal without stopping water running

Abstract

The novel green dredging device comprises a dredging ship, wherein a dredging mechanism is loaded on the dredging ship and comprises an outer frame and an inner dredging box body, only the bottom faceof the outer frame is open, the outer frame and the bottom end of the inner dredging box body are connected together in a sealed mode, a sealed cavity is formed between the outer frame and the innerdredging box body, a pressure sensor is arranged at the bottom of the outer frame, air knife mechanisms are arranged at the bottoms of two opposite side faces of the inner mechanism box body, a flushing and spraying mechanism is arranged at the position, close to the bottom, of one of the other two opposite side faces, and a mud pumping mechanism is arranged at the bottom of the other one of the other two opposite side faces. According to the novel green dredging device for the lined open canal without stopping water running, the mud at the bottom of the open canal can be cleaned under the condition that water running of the open canal is not stopped, large interference to surrounding water is avoided in a cleaning process, and secondary pollution to the surrounding water is also avoided;and sediments in the canal can be cleaned timely and efficiently, so that the use of manpower is greatly reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of open channel cleaning, and in particular relates to a new device for green dredging of lined open channels without stopping water. Background technique [0002] With the improvement of my country's water conservancy construction technology, large and medium-sized open channels are often open channels that stretch for thousands of kilometers. During the process of transporting water along the way, it is inevitable that dust in the air will be mixed with other impurities and microorganisms, and will settle down. At the bottom of the canal, it gradually accumulates to form silt, which breeds various microorganisms and benthic organisms; if things go on like this, it will inevitably affect the quality of water delivery and hinder people's normal drinking water needs. Due to the high water supply load of large and medium-sized open channels, it is usually not possible to stop water for dredging; if the silt at ...

AI Technical Summary

Problems solved by technology

These methods often cause great interference to the surrounding water body, and at the same time cause secondary pollution to the surrounding water body during the dredging period. If the cofferdam is used first and then the drainage is used to pump the sludge, for the continuous large and medium-sized water delivery channels, especially for the need For channels that are always in a state of water delivery and ensure water quality, it is usually difficult to achieve
