Abstract

The invention provides a single-unit hydraulic dredger. The dredger comprises a hull, a control device, a driving mechanism and a water spraying device, wherein part of the control device is arrangedon the hull and used for computing preset angle and preset pressure intensity when high-pressure water spraying is conducted by the water spraying device and controlling the driving device to drive the water spraying device to move to a preset position to perform high-pressure impacting on sludge, the driving device is arranged on the hull and used for driving the water spraying device to synchronously move to a preset position according to a preset trajectory to ensure the water spraying device can perform high-pressure impacting on the sludge according to a preset angle, and part of the water spraying device is arranged on the hull and used for performing high-pressure water spraying according to the preset pressure intensity to flush away the sludge at the bottom of a port. The dredgerhas the advantages that the problems of lower cleaning efficiency and poorer cleaning effect when port sludge is cleaned by an existing dredger are solved.

Description

technical field [0001] The invention relates to the technical field of dredgers, in particular to a single-unit hydraulic dredger. Background technique [0002] In recent years, the rapid development of my country's economy has brought about a boom in the construction of water conservancy and port and waterway projects. In order to meet the needs of navigation, new construction and expansion of ports, and to maintain the normal flood discharge and navigation capacity of inland rivers, the natural water depth is fully utilized. However, due to the sedimentation of the water body, the carried sediment and organic matter enter the water to form a hyperpycnal flow, resulting in serious sedimentation of the river bed, and the natural water depth often does not meet the requirements and needs to be dredged. As a result, a series of technical problems have arisen, such as different properties of sediments, and higher requirements for underwater dredging equipment are also put forw...
