A kind of deep-sea aquaculture cage inspection device and inspection method

Abstract

The invention relates to a deep-sea culture net cage inspection device, which includes a hangar and an inspection robot, and also includes a deep-sea culture net cage. An installation base is fixed on the deep-sea culture net cage, and a Deep-sea aquaculture cage control center, the installation base is fixed and rigidly connected to the hangar, and the inspection robot is placed on the top of the hangar, and the hangar is connected to the deep-sea aquaculture cage control center through an umbilical cable to form a power supply and communication channel , The inspection robot and the hangar realize the transmission of electric energy and information through underwater wireless transmission technology. The inspection device is permanently stationed in the deep-sea aquaculture cage, and the cage netting can be inspected periodically or independently according to the shore-based remote command, and the inspection data is sent to the shore-based center through the cage control center for inspection. Analysis of test results.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an inspection device and an inspection method for deep sea culture cages. Background technique [0002] China is a superpower in marine fish farming. With the increasingly serious pollution of coastal farming, intelligent, automated, and scientific deep-sea farming has become the development direction of marine fish farming. Among them, the development of large-scale deep-sea farming cages and supporting facilities Particularly important. Fishing net damage and fishnet biological climbing and breeding are common problems in the deep-sea cage culture process. Fishing net damage can easily cause fish to escape or the top of the food chain to mix in, resulting in a decline in fish production; fishing net biological climbing and breeding affect the water body in the cage Metabolic rate, and affect water quality, resulting in a decline in fish quality, therefore, the inspec...

Problems solved by technology

However, ROVs can only be operated by personnel. Operators need to process a large amount of information and operate ROVs frequently. The work intensity is high and the work efficiency is low. At the same time, because ROVs are mostly open-frame structures and the netting is made of flexible materials, ROVs are easy to operate if improperly operated. Intertwined with net clothing, affecting inspection operations

At the same time, since deep-sea aquaculture cages are mostly in the open sea, far away from the land, the above two methods need to transport personnel and equipment to the sea area where the deep-sea aquaculture cages are located by surface ships and then carry out operations, which are greatly affected by sea conditions and weather conditions, and the cost is high , less economical
