Environmental protection dredging device based on hydraulic engineering

Abstract

The invention discloses an environmental protection dredging device based on hydraulic engineering. The environmental protection dredging device comprises an air reservoir of which the lower end is provided with an annular connecting base, and the annular connecting base is provided with connecting threaded holes; the upper end face of the air reservoir is provided with a plurality of air pumps distributed uniformly, and an output port of each air pump is connected to the interior of the air reservoir; and the middle part of the upper end face of the air reservoir is provided with an air outlet pipe of which the upper end is connected to one end of an air delivery hose. The environmental protection dredging device is simple in structure and easy to use, and sludge on a riverbed can be flushed away through an air impingement stirring structure, and then sludge at the bottom of the riverbed is taken up to higher water level through air impingement; adverse effects of repeated precipitation of the sludge on river dredging are reduced, and the river dredging efficiency is improved effectively; meanwhile, damage to the pump bodies due to blockage is avoided effectively with an air impingement dredging method, and the riverbed dredging cost is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to an environment-friendly desilting device based on water conservancy engineering. Background technique [0002] River dredging is an important part of water conservancy projects. Its main function is to stir up the silt existing at the bottom of the river, and then wash away the stirred up sludge through the river, thereby dredging the river. For example, the application publication number The patent of 201721289922.4 discloses an environmental protection desilting device based on water conservancy engineering, but there are certain defects in the use of the above patents. The patent uses stirring to mix the silt and water, and then dredges the silt in the river to play a role. To dredge the river, but through the dredging method of stirring, the depth of the silt that the device can stir is limited. At the same time, most of the silt is still located in the ...

[0002] River dredging is an important part of water conservancy projects. Its main function is to stir up the silt existing at the bottom of the river, and then wash away the stirred up sludge through the river, thereby dredging the river. For example, the application publication number The patent of 201721289922.4 discloses an environmental protection desilting device based on water conservancy engineering, but there are certain defects in the use of the above patents. The patent uses stirring to mix the silt and water, and then dredges the silt in the river to play a role. To dredge the river, but through the dredging method of stirring, the depth of the silt that the device can stir is limited. At the same time, most of the silt is still located in the part with a low water level during the stirring process and will soon settle again. Such a dredging effect bad
