Abstract

The invention discloses a fixed multifunctional underwater sediment collector and a use method, the sediment collector comprises a cable and a grab bucket, the sediment collector also comprises a shell, wherein the shell is provided with a cable hole for the cable to pass through; a rotating shaft, wherein the two ends of the rotating shaft are rotationally connected with the inner walls of the two sides of the shell correspondingly; a winding roll which is fixedly connected with the rotating shaft in a sleeving mode, wherein the cable can be wound on the winding roll; a driving motor which is arranged on the shell, wherein the driving motor can drive the rotating shaft to rotate; and a first locking device, wherein the first locking device can lock the rotating shaft. Rotation of the rotating shaft is controlled through the driving motor, so that winding and unwinding of the cable are controlled, time and labor are saved, the cable does not need to be manually dragged for winding and unwinding, and use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of sediment collection equipment, and in particular relates to a fixed multifunctional underwater sediment collector and a using method. Background technique [0002] In environmental radioactivity monitoring, the monitoring of underwater sediments such as rivers, lakes and seas is an important monitoring content. Especially in the waters around nuclear power plants, radionuclides will be adsorbed and deposited in seabed mud, causing a series of radioactive pollution. Therefore, the monitoring of underwater mud is very important, and it is necessary to collect underwater sediments to detect the content of radioactive substances in them. [0003] Currently commercially available sediment samplers are just a rope and a grab, such as Figure 7 shown. In the process of use, there are the following problems: 1. It does not have the function of being fixed on the side of the ship. It is very laborious to retract ...
