Deep-sea aquaculture net cage capable of accurately feeding baits

Abstract

The invention discloses a deep-sea aquaculture net cage capable of accurately feeding bait, and belongs to the technical field of deep-sea aquaculture, the deep-sea aquaculture net cage comprises an integrated mounting frame, an induction type bait feeding mechanism, a regulation and control cable, a waste collection and load bearing integrated assembly and a coiling regulation and control assembly, the coiling regulation and control assembly is fixedly mounted at the top of the integrated mounting frame, and the coiling regulation and control assembly is fixedly mounted on the top of the integrated mounting frame; the induction type bait feeding mechanism is arranged in the integrated mounting frame in a penetrating mode and connected with the winding regulation and control assembly, the positions of most fish schools are judged through instruments such as a camera and a sonar, then the induction type bait feeding mechanism is controlled to descend to the position of the most fish schools, feeding is conducted after luring is conducted, and the fish feeding efficiency is improved. According to the position of a fish school, underwater accurate feeding is achieved, feed waste is reduced, fishes are limited through the integrated mounting frame, the situation that cultured organisms fight for food or wild small fishes fight for food to block a discharging port is prevented, the device can move along with lifting of the induction type bait feeding mechanism, an additional driving structure is not needed, and cost is saved.

Description

technical field [0001] The invention relates to a net cage for deep-sea culture, in particular to a net cage for deep-sea culture that can accurately feed bait, and belongs to the technical field of deep-sea culture. Background technique [0002] Deep-sea aquaculture usually refers to a sea area far away from the mainland with a water depth of less than 20 meters, relying on equipment such as aquaculture workboats or large-scale floating aquaculture platforms, supporting deep-sea cage facilities, fishing boats, energy supply networks, logistics supply ships and land-based support facilities. Composed of a comprehensive fishery production system that integrates industrialized green farming, catch loading and material supply, marine product processing and logistics, and digital management, it is a new fishery production system that combines "breeding-catching-adding" in the whole industry chain. This new farming model has high requirements on marine equipment and technology, a...

Problems solved by technology

[0004] In the invention patent with the application number CN201610365276.9, a semi-submersible and full-submersible deep-sea culture cage integrating wave energy and solar power generation is proposed, which integrates wave energy power generation and solar power generation, and utilizes on-site resources Realize the complementary power supply of renewable energy, satisfy the use of clean power in open sea net cages, and solve the problem that deep sea net cages cannot realize energy supply. The patent proposes a deep-sea culture cage that can simultaneously breed fish and scallops, which can effectively use the space of the culture cage and simultaneously breed fish and scallops. The convenient cleaning function doubles the economic benefits of aquaculture cages and greatly reduces the workload of farmers. Although it has a certain improvement compared to the existing aquaculture cages, it does not improve the deep sea aquaculture. According to our actual observation, when the current deep-sea culture cages are feeding, the bait needs to settle for a while to attract fish to grab food, and there will be a waste of bait. Most of them do not have the function of waste collection, but the function of waste collection is realized. Most of them need to be carried out on the seabed, and additional driving structures are required. The feeding of bait also requires a driving structure, which is too costly and inconvenient to arrange. Therefore, we propose a deep-sea culture cage that can accurately feed bait
