Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture, and particularly relates to an underwater automatic feeding device for a turnover type marine ranch. BACKGROUND

[0002] In recent years, with the continuous development and improvement of intensive aquaculture technology, the aquaculture mode is changing, and the large-scale and intensive aquaculture brings the problem of feeding difficulty which has not been well solved. At present, artificial feeding is mainly used in aquaculture, and there are problems such as high labor intensity, low efficiency, and difficult control of bait quantity, so it is very important to find a scientific and reasonable bait feeding technology for the breeding effect and ecological environment. The feeding machine has the advantages of saving the working intensity of the breeding personnel, remarkable economic benefit and the like, and has become an important part of the modern aquaculture machinery. At present, there are many researches on the automatic feeding system at home and abroad, and there are many applications in pond culture, factory culture and net cage culture, but the feeding systems are different in different breeding environments, and there are different specific forms under the same basic structure mode.

[0003] Unlike pond culture, marine culture requires breeding personnel to start from the shore, transport feed to the breeding platform for a long distance, and then manually feed in the net cage. The workload is much larger than that of pond culture. If there are multiple platforms to be fed, due to the long transportation distance, large feeding quantity and unstable weather factors, not only the workload is greatly increased, but also the work efficiency is greatly reduced. In addition, unlike the pond culture which can arrange a large number of breeding devices based on land, the space resource of the breeding mode based on the marine platform is very limited, and the energy system, lighting system, monitoring system and various function rooms on the platform all occupy the land area, which compresses the available space of the feeding device. Therefore, it is very important to realize the unmanned and intelligentization of marine culture with the minimum space occupation rate and simplify the feeding process.

[0004] Among many structural forms of marine culture platforms, compared with the traditional fixed net cage, the turnover type net cage is convenient to turn the bottom net to the upper part for drying and cleaning, which greatly improves the feeding environment and improves the fish quality. However, since the turnover type net cage needs to be turned over regularly, if the feeding device is arranged on the side of the net cage to feed the inside, the feeding pipe needs to be recovered every time the net cage is turned over, and the pipe needs to be arranged again after the net cage is turned over. The process is too cumbersome. At the same time, for a 50*20*10m marine ranch for feeding large yellow croaker, the daily feeding quantity of dry feed is about 3m3, and the feeding quantity of 7 days is about 20m3, which occupies too much working space.
