Survey ship for detecting silt and method for detecting silt using the survey ship

Abstract

The application relates to a survey ship for detecting silt and a method for using the survey ship to detect silt, including a hull, a positioning system and a control system are arranged on the hull, the positioning system and the control system are connected by communication, and the positioning system transmits position signals to the control system The system is compared with the position signal set in the control system. There is a measuring device on the hull. The measuring device includes a sounding probe and a sounding rope. The sounding probe communicates with the control system; On the hull, a meter counting component is arranged on the hull, one end of the sounding rope extends into the water, and a weight is arranged on the end of the sounding rope extending into the water. The control system of this application controls the work of the sounding probe, measures the current water depth h1, and uses the meter counting component to measure the length h2 of the sounding rope, and then calculates the value of h2 minus h1 to obtain the thickness of the silt, reducing manual labor. The steps of operation and recording reduce the deviation of measurement results.

Description

technical field [0001] The present application relates to the technical field of water body survey equipment, in particular to a survey ship for detecting silt and a method for using the survey ship to detect silt. Background technique [0002] Silt is a component of water body sediments, and generally refers to the part distributed in the upper layer of sediments with high content of various nutrients and toxic and harmful substances. It is characterized by high water content (generally exceeding 60%), large void ratio, and nutrients. High in salt. Silt is the carrier of long-term accumulation of water pollutants, which belongs to endogenous pollution, and has become an important factor for black and odorous water bodies in some urban water bodies. As an endogenous source of pollution, silt continuously releases nutrients and various toxic and harmful substances, which seriously affects the water quality and the survival of various aquatic organisms. In addition, the surf...

Problems solved by technology

[0005] For the related technologies mentioned above, the inventor believes that there are the following defects: after the staff arrives at the measurement point, they first touch the special measuring rod to the surface of the mud and read the depth value, then insert the standard measuring rod into the mud, and the experienced personnel measure When the staff judges that the standard measuring rod has touched the bottom silt, read another depth to calculate the thickness of the silt. The whole process requires continuous manual operation and recording, which can easily lead to deviations in measurement results.
