Underwater towed system for near-shore seabed habitat observation

Abstract

The invention discloses an underwater towed system for near-shore seabed habitat observation. The system comprises a mother ship and an underwater towed device, wherein an underwater high-definition camera, an underwater LED light source, an underwater DC power, a methane sensor, a dissolved oxygen sensor, a carbon dioxide sensor, a particle size instrument and so on are installed on the underwater towed device, the underwater towed device comprises a towed body frame, tail boards and a towed board, the tail boards are symmetrically arranged at two sides of an upper layer of frame, a connection board is arranged between two tail boards so as to make the connection firmer, the tail boards makes towing more stable so as to guarantee video imaging effect, the towed board is arranged in the middle in front of the upper layer of frame, the towed board is provided with multiple adjusting holes, the towed board is connected with the mother ship through an armored cable, the position of the towed position of the towed board is adjustable, so that the towed board is suitable for different work conditions, and the mother ship proceeds so as to perform the towing operation. The system carriesthe high-definition camera and various sensors, thereby being capable of monitoring multiple physical quantities once, and monitoring various near-shore environment factors all round.

Description

technical field [0001] The invention belongs to the application technical field of marine detection devices, and in particular relates to an underwater towing system for near-shore seabed habitat observation. Background technique [0002] With the development of the coastal economy, the development intensity of the coastal zone and offshore ocean is also increasing day by day, and the pressure on the marine environment and marine ecology is increasing. It is closely related to marine fishery resources. In recent years, the problem of seabed habitat has gradually attracted the attention of the international ecology, environment, and fishery fields. In recent years, my country has gradually incorporated the concept of habitat into marine work. The geology, landform, and water environment quality of the seabed are important environmental elements of marine habitats. Seabed survey techniques and methods in nearshore shallow water areas (water depth <100m) have long been affe...

AI Technical Summary

Problems solved by technology

The geology, landform, and water environment quality of the seabed are important environmental elements of marine habitats. Seabed survey techniques and methods in nearshore shallow water areas (water depth <100m) have long been affected by reasons such as nearshore water depth, lack of shipborne acoustic and optical instruments and equipment, etc. It is difficult to make a breakthrough. The rapid development of unmanned ships and other means in recent years is difficult to be applied in the field of seabed habitat survey due to the complex offshore traffic environment, large waves, and high water turbidity. For example, multi-beam, single Beam surveys or side-scan sonar methods are not effective and efficient, and are not conducive to actual observations. It is urgent to propose an effective and comprehensive observation scheme for near-shore seabed habitats
