Description

A dredging device for river management

technical field

The utility model belongs to the technical field of river channel regulation, in particular to a dredging device for river channel regulation.

Background technique

River regulation, also known as "river regulation", is an engineering measure to control and transform the river. Scouring and silting often occur in natural rivers, which are prone to water damage and hinder the development of water conservancy. In order to meet the requirements of eliminating disasters and promoting benefits, appropriate measures must be taken to regulate the river, including engineering, dredging and revetment. During river regulation, it is necessary to clean up the silt inside the river, and dredging equipment is required.

Patent CN202221187700.2 discloses a water conservancy dredging suction port, which includes a dredging pipe, a rotary filter ball, a ring brush, and a grid cover. The dredging tube has two bearings near the nozzle. Utilizing the dredging and suction water flow in the suction pipe, it drives the rotating filter ball to rotate to prevent the suction port from being blocked. It does not require electrical equipment and consumes extra energy. It is low in manufacturing cost, light in weight, easy to operate, and reduces labor intensity.

Above-mentioned patent does not consider the impurity removal problem in the dredging work.

Therefore, the traditional dredging devices currently on the market have relatively simple functions and are very inconvenient to use. When the traditional dredging devices are in use, because a large amount of sundries are mixed in the river silt, if the silt is directly sucked, it is easy to cause blockage of the pipeline, and the dredging efficiency is low.
