Embodiment Construction

[0028] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 1-3 As shown, in a specific implementation case of the present invention, a towed water body horizontal and vertical profile chemical observation system includes a towed body system, an observation load system, an acquisition system, and an electronic control system.

[0030] In this embodiment, the drag body system includes a hydroelectric coaxial cable 1; a connector 2; a bow 3; a horizontal wing 4a; a vertical wing 4b; The hydroelectric coaxial cable 1 is connected to the ship and the tow head 8 through the connector 2, and can collect sensor data and water samples of the tow body during the voyage. When towing, the bow 3 is forward, and its streamlined design can reduce water flow resistance. Empennage blades 7 on the stern 6 can reduce the drag caused by turbulence. The horizontal wing 4a can adjust...

Abstract

The invention discloses a drag system for observing water transverse and longitudinal section chemical parameters. The drag system comprises a dragger system, an observation load system, an acquiringsystem and an electric control system. An armored cable is connected with a dragger fore body through a connecting head, and is dragged to advance in water; the dragger fore part comprises a water inlet pipe inside for acquiring water samples; wings are positioned on the two sides of a dragger, can be rotated to change angles for climbing or descending during navigation to enable the dragger to observe at a fixed depth, or can perform an up-down or left-right horizontal W type motion for 200 m water-depth longitudinal or 200 m-width transverse section chemical parameter measurement; and various chemical sensors, the acquiring system and the electric system are loaded at the middle part of the dragger after weight adding. The acquiring system is used for acquiring data of the chemical sensors and the water samples, which are sent to a ship deck through the special-machined armored cable. The electric control system can adjust attack angles of the wings according to depths and dragger postures to determine navigation depths and trajectories.

Description

technical field [0001] The invention belongs to the technical field of marine online monitoring, is suitable for high-resolution profile observation of lakes, rivers, and oceans, and in particular relates to a towed system for observing chemical parameters of horizontal and vertical profiles of water bodies. Background technique [0002] The chemical properties of natural water bodies are the basis for the formulation of environmental protection policies and the research on the mechanism of marine disasters such as red tide and anoxic water bodies, while the euphotic layer of water bodies shallower than 200 meters is a place where human activities and water biological activities are frequent. Therefore, how to obtain chemical data with high spatio-temporal resolution shallower than 200 meters is the key. At present, the main means are fixed-point water collection or navigation survey on the ship base, or observation by mooring with chemical sensors. However, ship-based fixe...
