Problems solved by technology

[0003] At present, due to the different physical fitness of the sampling personnel and the different depths of the lake, the safety of manual collection of sediment samples is insufficient, and the amount of collection is also limited. The large-scale lake sediment sampling equipment has a complicated structure and requires a series of Equipment for coordination and mobilization

Abstract

The invention discloses a river and lake sediment sampling device, and belongs to the technical field of underwater sediment sampling, the river and lake sediment sampling device comprises a tool ship, a loading corridor is reserved on the tool ship, a sampling port is formed in the center of the loading corridor, and a lifting fence is arranged at the position of the sampling port; a first lifting table, a second lifting table and a third lifting table are arranged at the upper end of the lifting fence, a first winch is fixedly arranged on the first lifting table, a second winch is fixedly arranged on the second lifting table, a third winch is arranged on the third lifting table, and the first winch, the second winch and the third winch are connected with a grab bucket mechanism through ropes. According to the underwater sediment grabbing device, by means of cooperation of rope unwinding and rope winding operation of the three winches, adjustment control over opening and closing of the grab bucket mechanism is achieved, then the grab bucket mechanism is conveniently used for grabbing underwater sediment, the structure is simple, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of underwater sediment sampling, in particular to a river and lake sediment sampling device. Background technique [0002] The research and protection of lake water environment related issues involve both lake water quality and sediment. Lake sediment, as an important part of the lake water environment, receives the input of pollution from the watershed, and truly records the long-term pollution load of the watershed. The evolution history of input and lake environment, so the study of sediments is essential. Usually, the study of sediments is to collect sediment samples from the bottom of the lake to carry out simulation experiments in the laboratory, and to carry out scientific research on related issues; [0003] At present, due to the different physical qualities of the samplers and the different depths of the lakes, the safety of artificial collection of sediment samples is insufficient, and the collect...
