A drag-type multi-parameter profile measurement system and measurement method

Abstract

The invention discloses a towed multi-parameter profile measurement system and a measurement method. The measurement system includes a towing body, a collar-type towline, and a first line roll and a second line roll installed on the deck of a mother ship; the loop-type towline It includes a first cable and a second cable, the second cable is connected to the first cable through a collar, one end of the first cable is connected to the first line roll, the other end is connected to the drag body, and one end of the second cable is connected to the second line roll , the other end is connected to the collar, driven by the second wire roll, the second cable slides up and down relative to the first cable; the second cable is provided with a plurality of sensor integrated collection cabins at intervals, while ensuring that the position of the towing body remains unchanged Under normal circumstances, the measurement of chemical and biological characteristics in different section depth ranges can be realized to ensure the timeliness of data, and electromagnets and gravity probes are also installed on the drag body, and the structure of electromagnetic adsorption and release enables the device to realize underwater Sediment, water body multiple times, continuous change point measurement method.

Description

technical field [0001] The invention belongs to the technical field of marine observation equipment, and in particular relates to a towed multi-parameter profile measurement system, which is used to detect various physical and chemical parameters of seawater and seabed sediments in a certain sea area, as well as seabed topography and geomorphology, and realize ocean profile and Efficient detection of seabed topography and landforms. Background technique [0002] The perception and understanding of the ocean depends largely on the advancement of ocean observation and detection technology and the development of equipment. my country's marine technology and equipment have made great progress and development, especially in recent years, the development of marine technology and equipment has provided new impetus for the innovation of my country's marine science. Among the many submarine observation technologies, the towed observation platform is undoubtedly the most efficient ob...

Problems solved by technology

However, because the towing body is limited by the retractable cable, it is generally used to move at a certain depth

At the same time, due to the particularity of the drag body, the current drag body device cannot directly obtain the soil mechanical properties or chemical properties of the shallow surface sediment on the seabed

However, the chemical and biological characteristics of seawater often show different change characteristics in the longitudinal section of seawater. Measuring only the chemical and biological characteristics within the fixed depth range cannot reflect the longitudinal changes of seawater.

When measuring different depths, the existing method needs to adjust the depth of the towing body, but this method needs to travel the route again, resulting in low efficiency. At the same time, because it does not have the timeliness of data collection, it is difficult to collect data in the same direction. Compared

At the same time, for the detection of the mechanical properties of the existing shallow surface sediments, when detecting in deep water areas, the detection device needs to be lifted and lowered again when changing the location, resulting in low detection efficiency
