An underwater autonomous agile fishing device

Abstract

The invention relates to the technical field of automatic underwater fishing device, and provides a device capable of automatically identifying, automatically locating and swiftly fishing specific precious marine organisms which are bred dispersedly underwater at offshore and neritic areas. The device takes a general-assembly support as a basic structural body and carries a visual system module, an electronic cabin module, a transmission system module and a fishing execution mechanism module; the device can achieve the underwater operation functions of automatic identification, automatic location and swift fishing under offshore and neritic area environments, and the intelligence level of underwater fishing and the fishing efficiency can be improved. Meanwhile, the device can be mounted onan underwater operation robot to conduct underwater robot fishing, therefore, the labor cost and labor production accidents can be reduced, and the accuracy and efficiency of fishing are improved.

Description

technical field [0001] The invention belongs to the technical field of underwater autonomous fishing devices, and in particular relates to a device capable of autonomously identifying, locating and rapidly fishing specific marine rare organisms that are spread and cultured underwater in near-shallow sea areas. Background technique [0002] The development of the ocean is a major issue faced by mankind in the 21st century, and the exploration, investigation and effective use of the ocean pose a challenge to the development of high-tech marine technology and the future marine industry in our country. Human beings are currently facing three major problems of population, resources and environment . In order to survive and develop human beings, marine development is imperative. [0003] Near-shallow waters are an important class of marine resources. Our country has abundant fishery resources in near-shallow waters, which provide many necessary products for people's life. The d...

Problems solved by technology

At present, due to the immature technology of force sensors, especially patch sensors, the clamping force of the fishing manipulator claws cannot be accurately closed-loop controlled according to the softness and surface roughness of the fish, and the opening distance of the grasping hand cannot be controlled according to the size of the fish. The size and shape are automatically adjusted, which may easily cause damage to the catch, or fail to catch successfully, resulting in low fishing efficiency
