Method for automatically dragging scrap iron in river

Abstract

The invention provides a method for automatically dragging scrap iron in a river. The method comprises the following steps: (S1) placing a dragging machine, which comprises a floating frame, a movingunit, an underwater lifting and lowering frame, a scrap iron adsorption mechanism, an air floating lifting and lowering mechanism, a lifting and lowering supporting device, a remote control for controlling the moving unit, and an air storage tank arranged on the floating frame, into the river and debugging the dragging machine; (S2) starting the dragging machine to drag the scrap iron in the river, controlling the movement direction of the floating frame by virtue of the remote control to gradually and comprehensively drag in the river, and controlling the opening and closing of an air inlet valve and an emptying valve, and the lifting and lowering of the underwater lifting and lowering frame by virtue of the remote control so as to drag the scrap iron at different depths in the river; (S3) controlling the floating frame to come alongside by virtue of the remote control and manually removing the scrap iron on magnetic suction disks when the river clearing is completed or a weighing sensor detects that the weight of the scrap iron reaches a set value.

Description

technical field [0001] The invention relates to an automatic salvage method for scrap iron in a river course. Background technique [0002] In the prior art, scrap iron is usually left in the river. For a long time, the scrap iron has been deposited at the bottom of the river, which not only pollutes the environment, but also cannot be recycled, resulting in a waste of social resources. In the prior art, there are also salvage ships in the river to salvage, but for Salvage ships cannot enter the narrow river, and salvage ships usually use manual salvage during the salvage process, which is time-consuming and laborious. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide an automatic salvage method for scrap iron in a river, which can automatically salvage scrap iron sunk in the bottom of the river, saving time and effort. [0004] In order to achieve the above object, the technical sol...
