Embodiment Construction

[0027] Embodiments of the present invention are described in detail below. The present embodiment is based on the technical solution of the present invention and provides detailed embodiments and specific operating procedures, but the scope of protection of the present invention is not limited to the following embodiments.

[0028] The lake internal source pollution control underwater robot described in this embodiment includes figure 1 The robot shown and figure 2 The workboat shown in conjunction with the robot.

[0029] Such as figure 1 As shown, the arrow points to the direction of travel of the robot during operation. The robot housing 1 is 4-5m long (traveling direction), 3-4m wide, and 0.6-0.8m high, and the bottom of the vertical skeleton is connected with telescopic parts 6 (spring legs); Install a wide 15~20cm crawler bearing plate 12. The spring legs cooperate with the crawler-type bearing plate, so that the robot can slide on the uneven mud surface.

Abstract

The invention discloses an underwater robot for treatment of endogenous pollution in a lake water body and a method for cleaning deposition pollutants. Needed equipment includes the underwater robot and a matched working ship. The robot is provided with an airbag and multiple thrusters for no-load sinking and floating, advancing and retreating and steering; and the casing of the robot is provided with a colter and a jet flow row for turning and scouring the deposition pollutants to disperse the dispersion pollutants in a water phase. Under the condition of same system settlement time and settlement interval, coarse particle mud and sand in the water phase are settled to form a new covering layer, and fine particle pollutants and algae cells are suspended in washing water. The working ship provides power and airflow for the robot and controls procedures. When in working, the robot is sank to the bottom, and pulled by a winch of the working ship to walk on mud surface. The washing water discharged by the robot is transported to the working ship by a high-pressure hose for pollutant / water separation, clear water is returned back to a lake, the pollutants and algae seeds are filtered by pressing for volume reduction, bagged and taken to a bank, and dual purposes of endogenous pollution transfer and in situ covering of bottom mud can be achieved.

Description

technical field [0001] The invention relates to a eutrophic water treatment and ecological restoration technology, in particular to an underwater robot for the treatment of internal source pollution in a lake and a cleaning method for deposited pollutants. Background technique [0002] In the past hundred years, lake eutrophication has generally occurred in the world. According to statistics, my country's eutrophic lakes account for 56% of the total number of statistical lakes. Many large lakes, such as Taihu Lake, Chaohu Lake and Dianchi Lake, are in a state of severe eutrophication, which has become a very prominent water environment problem in our country. [0003] The sources of eutrophic water pollution are divided into external sources (point sources and / or non-point sources) and internal sources. Exogenous pollution can be comprehensively controlled from the source to reduce the input of pollutants. For lakes with light pollution, reducing exogenous pollution can i...
