Device for repairing deepwater net cage netting

Abstract

The invention discloses a device for repairing a deepwater net cage netting. The device comprises an open frame type underwater robot and a deepwater net cage netting repairing mechanism; the deepwater net cage netting repairing mechanism comprises a netting hole penetrating mechanism, a wire feeding mechanism, a rotary knotting mechanism, a steel wire cutting mechanism and a steel wire clamping mechanism; the netting hole penetrating mechanism comprises mechanical claws and a control box for controlling the mechanical claws; the wire feeding mechanism and the steel wire cutting mechanism are both fixedly arranged in the control box; the steel wire clamping mechanism and the rotary knotting mechanism are both arranged between the two sets of mechanical claws; and the open frame type underwater robot is detachably connected with the deepwater net cage netting repairing mechanism through a connecting shaft. When large holes are formed, the opening angle is increased by driving the two mechanical claws, and the large holes of the netting are repaired in combination with multiple times of repairing, so that huge economic losses and biological environment pollution caused by escape of large-scale fishes are avoided. And the device is high in realizability, safe and reliable in operation, high in portability and high in integration degree.

Description

Technical field [0001] The present invention relates to the field of marine fisheries, in particular to a device for repairing a deep water jacket. Background technique [0002] Marine fisheries refers to the production undertakings engaged in marine fishing and seawater farming. Actively develop marine fisheries, providing people with a large number of animal proteins, providing important commodities for foreign trade, helps to alleviate the contradictions in my country's people, which is important to develop the national economy. [0003] However, traditional extensive consumption fisheries production models have led to serious damage to large seas, and a series of aquarium disease is serious, and the deterioration of aquaculture environment has seriously constrained the sustainable development of aquaculture industry. [0004] Deep water cage breeding is mainly on the underwater environment away from land and the environment, deep water box mesh clothes are extremely damaged u...

Problems solved by technology

However, the use of the whole piece of net clothing butt repair technology (patent number: CN201920651248.2) only exists in theory, and there are a series of difficult-to-control problems, which cannot be used as a sustainable development technology

As for the technology of using ROV to carry the repairing device, the current domestic technology is only a kind of underwater robot for repairing nets in deep sea cages from Ocean University of China (patent number: CN202011621251.3), but its production process is complicated, and the carrying mechanism is divided into two parts: The two independent mechanisms of net repair and net knotting have low feasibility and difficult operation in complex underwater environments, and the quality of net repair is low
