Problems solved by technology

[0004] In the existing dredging device, there is a dredging robot, which can realize relatively flexible dredging action through the boom, and can be used in the built area. However, the inventor believes that the current river dredging machine is still Excavation and suction of silt are the main cleaning methods. During the dredging process, it is necessary to consider where to discharge the silt. It needs to be equipped with transport vehicles, and it is easy to pollute the air; and it does not take into account the seasons of the river or artificial canal itself. sexual characteristics

Embodiment 1

[0029] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses a dredging device using hydraulic pressure, including a base 3, a track 4, a water pump and a mechanical arm, the mechanical arm is hinged to the base 3, the base 3 is slidably connected to the track 4, and the track 4 is fixedly arranged on the ground , the base 3 is equipped with a power source and can slide along the track 4; the water pump is connected to the water pipe 10, and the end opening of the water pipe 10 is connected to the mechanical arm. When the mechanical arm moves, the end opening of the water pipe 10 sprays water pumped out by the water pump. The water column formed by the water can impact the silt.

[0030] The mechanical arm includes a first arm 1, a second arm 2, and a third arm 5 that are articulated in sequence, wherein the bottom end of the first arm 1 is fixedly connected to the base 3 for movement and stability, and the second arm 2 is longe...

Embodiment 2

[0045] In a typical implementation of the present invention, this embodiment discloses a method for dredging a river, using the dredging device utilizing hydraulic pressure as described in Example 1, comprising the following steps:

[0046] 1) Select the desilting time. Choose the wet season of the river channel, preferably the flood season. During this time period, using the characteristics of large water volume and fast flow rate in the flood season of the river channel, it is beneficial to break the static balance of the silt with water pressure and form a suspended state. The silt in this section of the river will be cleaned up.

[0047] 2) Arrange track 4. At the river bank along the river, track 4 is arranged, and track 4 needs to be as parallel as possible to the direction of the river.

[0048] 3) delineate the cleaning area, according to the width of the river channel, and the coverage area of ​​the nozzle 9, the river channel is divided into several cleaning areas;...

Abstract

The invention discloses a desilting device utilizing water pressure and a riverway desilting method, and belongs to the field of excavators. The desilting device comprises a base, a track, a spray head and a mechanical arm, the mechanical arm is hinged to the base, the base is slidably connected with the track, and the track is fixedly arranged on the ground; and a main rod and a plurality of supporting rods with one ends hinged to the main rod are arranged at the tail end of the mechanical arm, the supporting rods can rotate around hinge points, and the sprayer is fixedly connected to the supporting rods and further in communication with a water source. The equipment is laid on the track so as to move conveniently, water pressure is guided into the water bottom by means of the pipeline todisturb silt, static balance of silt is broken through by means of the water pressure by means of the characteristics of large water volume and high flow speed in the flood season of a riverway, a suspended state is formed, and the silt in the river reach is cleaned through water flow in the flood season.

Description

technical field [0001] The invention belongs to the field of excavators, and in particular relates to a hydraulic dredging device and a river channel dredging method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The inventors found that the accumulation of silt in the existing rivers and lakes is becoming more and more serious, seriously affecting the ecosystem of the river, especially the silt contains a large amount of pollutants, pollutes the water source, and the silt accumulates higher and higher, raising the river bed. With the global With the increase of abnormal weather, rivers are prone to basin floods, and most of the silt is easy to concentrate at the bottom; and it is found that many dredging equipment need to empty the river to process the silt, which causes great damage to the ecology. In cities, most of the rivers have been repai...
