Dredging device for water conservancy project river channel

Abstract

The invention discloses a dredging device for a water conservancy project river channel, and belongs to the technical field of water conservancy projects. The dredging device for a water conservancy project river channel comprises a movable base, a plurality of gears A are symmetrically and rotationally connected to the outer side of the movable base at equal intervals in a linear mode through pin shafts, a silt collecting box is arranged on the rear side of the upper portion of the movable base, a silt outlet is formed in the lower end of the left side of the silt collecting box, a desilting groove is formed in the rear side of the interior of a desilting box, and a conveying belt is arranged on the front side of the desilting box; a plurality of excavating buckets are annularly arranged on the circumferential outer wall of the conveying belt at equal intervals, rotating shafts are in friction connection with the upper sides and the lower sides of the interiors of the excavating buckets, the outer ends of the rotating shafts are rotationally connected with holes formed in the inner wall of the desilting box, and due to tight cooperation of the structures, the defect that blockage is likely to happen due to the fact that a sludge pump and other equipment are arranged for extraction is effectively avoided, and cost is greatly saved; and through operation of the multiple excavating buckets, the efficiency of excavating the river silt is improved, even if blocky silt exists, the blocky silt can still be cleaned and removed, and the desilting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a dredging device for water conservancy engineering river courses. Background technique [0002] Water conservancy engineering is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. It is also called water engineering. Water is an indispensable and precious resource for human production and life, but its natural existence The state does not fully meet the needs of human beings. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of people's life and production for water resources. For some channels used for irrigation and water diversion projects, after a long period of use, silt will accumulate at the bottom of the channel, and the silt needs to be cleaned regularly...

Problems solved by technology

The prior art publication number is that the literature of CN210827639U provides a kind of desilting device for water conservancy engineering. The device can take the water source nearby by setting a water pump, stirring blades and nozzles, and generate water flow through the water pump to wash away the accumulated silt. The accumulated sludge is broken up by stirring blades, and the existing dredging device is easy to block the sludge pump when cleaning the sludge that has accumulated together for a long time and is relatively viscous, which brings inconvenience to the cleaning. Set up a sludge tank and a filter screen , the sludge can be filtered to make it easier to clean the sludge. Although the device has many beneficial effects, the following problems still exist: the device is equipped with a sludge pump to clean the sludge in the river, which is not only low in efficiency, but also easily occurs. In the case of blockage, it cannot work normally, and the device is equipped with fan blades on the outside for stirring, and the mud accumulated for a long time will only be pushed away, and the device cannot separate a large amount of water contained in the silt, which seriously wastes water resources , increased the load of the dredging device, and in addition, although the dredging device in CN2020205231499 in the prior patent technology can realize the separation of water in the sludge, it needs a high-power extraction device and the extraction method is vertical suction, so when encountering precipitation The long-term accumulated silt is easy to be stuck in the dredging operation scene, because the silt is easy to gather into blocks after being placed for a long time, and at the same time, it is difficult for the device to move forward through the rollers in the silt environment, and it will sink and cannot work. In view of this, we propose a dredging device for water conservancy engineering river
