Underwater desilting robot

Abstract

The invention provides an underwater desilting robot. By arranging nozzles around a silt suction cavity, high-speed jet flow is sprayed out to cut and disturb silt, the silt concentration is greatly increased, meanwhile parallel water curtains formed by the high-speed jet flow form a sectional negative pressure area, and the suction effect of a suction cup is ensured. By arranging a link mechanismin cooperation with a wheel-drive vehicle frame, underwater operations can be quite conveniently conducted, and the height of the suction cup is adjusted according to the silt height. By arranging adriving wheel comprising a roller and a spiral rib, on one hand, walking in the silt is facilitated, and wheels are prevented from sinking in the silt; and on the other hand, the silt can be stirred and dispersed so as to be conveniently sucked.

Description

technical field [0001] The invention relates to the field of underwater dredging equipment, in particular to an underwater dredging robot. Background technique [0002] With the increasing emphasis on environmental protection in our country, the dredging methods for urban rivers and lakes have become increasingly backward, and cannot meet the national requirements for environmental construction methods. For example, the old treatment methods generally include: the river channel is pumped with a cofferdam, and then dredged, which is time-consuming and labor-intensive, and the efficiency is extremely low. The lake is mainly constructed by cutter suction dredgers, but cutter suction dredgers are likely to cause noise pollution to the surrounding environment. In response to the above shortcomings, some units in my country have also developed some underwater dredging equipment, but the suction part still adopts the method of auger and liquid suction. For the silt with high conce...

Problems solved by technology

[0002] With the increasing emphasis on environmental protection in our country, the dredging methods for urban rivers and lakes have become increasingly backward and cannot meet the national construction method requirements for the environment.

For example, the old treatment methods generally include: the river is pumped with cofferdams, and then dredged, the disadvantage is time-consuming and labor-intensive, and the efficiency is extremely low

The lake is mainly constructed by cutter suction dredgers, but cutter suction dredgers are likely to cause noise pollution to the surrounding environment

In response to the above shortcomings, some units in my country have also developed some underwater dredging equipment, but the suction part still adopts the method of auger and liquid suction. For the silt with high concentration and strong adhesion, it is difficult to inhale directly through the suction part. It has the disadvantages of low slurry suction concentration and low dredging efficiency
