Multifunctional towed body raft auxiliary platform based on side scan sonar tail towing operation

Abstract

The invention discloses a multifunctional body towing raft auxiliary platform based on side scan sonar tail towing operation. The auxiliary platform comprises a frame and floating bowls. The frame comprises connecting rods and frame plates. The two frame plates are arranged in parallel at an interval. The two ends of the connecting rods are erected on the two frame plates respectively. The two floating bowls are arranged in parallel. The central axes of the floating bowls are perpendicular to the central axes of the connecting rods. The included angles between the central axes of the floatingbowls and the horizontal plane are acute angles. According to the auxiliary platform, through the platform design of a frame structure, a body towing raft device is more easily and rapidly manufactured, the required time is shorter, and expenditures are lower; the included angles between the central axes of the floating bowls and the horizontal plane are designed into the acute angles, the inclined axis installation mode is adopted, and the front end is slightly lower and the rear end is slightly higher. Since the height different exists between the front end and the rear end of the axis of each floating bowl, the overall balance performance of a body towing raft can be effectively adjusted, and the stability of the body towing raft in water is ensured.

Description

technical field [0001] The invention relates to the field of underwater detection and imaging instruments, and more specifically, relates to a multifunctional towing raft auxiliary platform based on side-scan sonar tail towing operations. Background technique [0002] Acoustic mapping technology is a very effective means of detecting the ocean. Using acoustic mapping technology, it is possible to detect seabed topography, observe ocean dynamic phenomena, detect seabed strata profiles, and provide submersibles with information for navigation, collision avoidance, and seabed contour tracking. With the development of marine resources and the development of marine economy in recent years, the state has paid more and more attention to the detection and analysis of seabed topography. Many scientific research units and teaching institutions have purchased side-scan sonar mapping systems. The currently commonly used C3D side-scan sonar mapping system has the advantages of high dete...
