Shallow water (less than 30m) instrument fishing method

Abstract

The fishing device comprises a buoyancy adjusting assembly, the buoyancy adjusting assembly is provided with a first frame body, a second frame body is arranged below the first frame body, a floating rod is arranged in the second frame body, the floating rod is of a rhombic hollow structure, a rotating floating body is arranged between the second frame body and the first frame body, and the rotating floating body is provided with a rotating shaft; a plurality of rotating blades are fixedly connected to the surface of the rotating shaft, the axis of the rotating shaft is located in the center of the buoyancy adjusting assembly, adjusting plates are arranged on the periphery of the rotating floating body, the two ends of each adjusting plate are fixedly connected with the first frame body and the second frame body correspondingly, and a plurality of adjusting blocks are hinged to the adjusting plates; water flow can be guided to the rotating floating body in the middle of the buoyancy regulation and control assembly, then high-flow-speed transverse wave and longitudinal wave water flow energy is consumed, advection can be formed near a water area to be fished, and the situation that the safety of divers is threatened or fishing operation cannot be conducted normally due to the too high flow speed of the water flow is avoided.

Description

technical field [0001] The invention relates to the technical field of fishing devices, in particular to a fishing method for shallow water (<30m) equipment. Background technique [0002] In many fields such as marine environmental investigation, seabed geological exploration, installation and maintenance of marine structures, water conservancy and hydropower engineering, and scientific investigation, it is necessary to use salvage devices to assist underwater operations. Establish real-time communication between the salvaged object and the hull, let alone accurately determine the specific coordinates of the salvaged object, and the device itself cannot overcome the water resistance, and the resistance of the water flow is relatively large, which affects the stability of the device and the safety when using the salvage device to salvage sex issue. [0003] Therefore, it is necessary to provide a fishing device to solve the above technical problems. Contents of the inve...
