Method for monitoring concentration of suspended matters in construction sea area by utilizing multi-layer distribution sampling device

Abstract

The invention discloses a method for monitoring the concentration of suspended matters in a construction sea area by utilizing a multi-layer distribution sampling device, and aims to solve the problemthat it is inconvenient to sample sea water of different depths in a construction sea area, and the monitored concentration value of suspended matters in the construction sea area is not accurate enough caused by the fact that the suspended matters diffuse to outwards easily due to that the construction sea area is open. A fence ring is arranged in the construction sea area, and a mechanical gripper is adopted for construction in a sea area defined by the fence ring, so that influence to the sampling accuracy caused by outward diffusion of the suspended matters is prevented; and openings in the lower end of a sampling pipe are formed in different water level positions, so that distribution sampling of a plurality of layers of water areas can be realized. In the construction process of themechanical gripper, a push rod is touched, and the push rod is driven to rotate anticlockwise, and the push rod abuts against a sealing cover and drives the sealing cover to rotate downwards, so thatthe openings in the lower end of the sampling pipe are opened, and the seawater in the opening positions at the lower end of the sampling pipe flows into the sampling pipe for sampling.

Description

technical field [0001] The invention relates to a seawater sampling method, more specifically, it relates to a method for monitoring the concentration of suspended matter in the construction sea area by using a multi-layer distributed sampling device. Background technique [0002] At present, during the operation in the construction sea area, it is necessary to regularly sample and detect the concentration of suspended solids in the seawater in the area. The traditional seawater sampling method is to directly throw the sampling bucket into the seawater, and pull the sampling bucket with a rope to sample the seawater. Sampling Lift the sampling bucket after the bucket is filled with seawater. This sampling method is convenient to operate, but it cannot sample seawater at different depths. Moreover, the construction sea area is open, and the suspended matter is easy to spread outward, so that the monitored concentration value of the suspended matter in the construction sea ar...
