Survey vessel for detecting sludge and method for detecting sludge by using survey vessel

Abstract

The invention relates to a survey vessel for detecting sludge and a method for detecting sludge by using the survey vessel, the survey vessel comprises a vessel body; a positioning system and a control system are arranged on the vessel body, the positioning system is in communication connection with the control system, and the positioning system transmits a position signal to the control system and compares the position signal with a position signal set in the control system; a measuring device is arranged on the vessel body, the measuring device comprises a depth measuring probe and a depth measuring rope, and the depth measuring probe is in communication connection with the control system; the depth measuring rope is movably arranged on the vessel body in a lifting mode, a meter countingassembly is arranged on the vessel body, one end of the depth measuring rope stretches into water, and a weight is arranged at the end, stretching into the water, of the depth measuring rope. The control system controls the depth measuring probe to work, the current water depth h1 is measured, the descending length h2 of the depth measuring rope is measured through the meter counting assembly, then the thickness of sludge can be obtained by calculating the value obtained by subtracting h1 from h2, the steps of manual operation and recording are reduced, and the deviation of the measurement result is reduced.

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.
