Multi-modular oyster breeding pasture and raft type wave energy integration device suitable for deep and far sea

Abstract

The invention discloses a multi-modular oyster breeding pasture and raft type wave energy integration device suitable for deep and far sea. The device comprises modular oyster breeding frames and raft type wave energy devices, wherein the raft type wave energy devices are arranged between every two adjacent modular oyster breeding frames. Under the action of wave load, the raft type wave energy devices are pushed to capture wave energy to generate power through relative movement between the modularized oyster breeding frames. Relative motion response generated between the breeding frames under the action of waves is effectively utilized, meanwhile, energy is absorbed through the raft type wave energy devices to reduce the motion response, structural safety is guaranteed, and long-term stable and efficient operation of large-scale modern marine ranch operation equipment, monitoring facilities and the like is achieved.

Description

technical field [0001] The invention relates to the technical field of deep-sea farming equipment and marine engineering, in particular to a multi-modular oyster farming pasture and a raft-type wave energy integration device suitable for deep-sea. Background technique [0002] With the rapid development of economy and society, people's demand for high-end oysters is increasing. Oysters have the advantages of short food chain, fast growth, high yield, wide distribution, high nutritional value, and good economic benefits. One of the aquatic products. However, the tight space for offshore aquaculture has limited the scale of aquaculture, the area of ​​traditional fishery waters has been decreasing, and the environmental pollution of offshore waters has become increasingly serious, which has brought about a series of problems such as industrial conflicts, ecological losses, disease risks, and quality and safety. At the same time, oyster farming in deep sea areas has the advanta...

AI Technical Summary

Problems solved by technology

[0003] At present, most marine aquaculture adopts a single module super large floating frame structure, which is huge in size, which leads to difficulties in manufacturing, transportation, installation, etc.

Due to its huge size, the aquaculture module will be subject to huge structural stress caused by the combination of external forces such as sagging, arching, and torsion. structural damage

[0004] In the prior art, there is a common problem of lack of offshore power resources in deep-sea farms, which has caused problems such as low breeding efficiency, low fishing efficiency, high labor intensity, and high risk factor in the production process of deep-sea farms, thus hindering modern marine ranches. development of

Secondly, the power supply of the existing deep-sea breeding farms is provided by diesel generators, and the diesel used needs to be supplied long-distance, and the transportation cost is high; limited by the harsh marine environment of the deep-sea, the refueling window of diesel generators is relatively short; and oil spills are prone to occur. Fault

Once the power supply of the diesel generator is interrupted, the breeding equipment and resource environment monitoring equipment of the breeding farm will not be able to operate stably for a long time

[0005] Common renewable energy in the ocean includes solar energy, wind energy, wave energy, etc. However, when using solar energy and wind energy in deep-sea breeding pastures, an independent support structure needs to be established, which increases the construction cost of the breeding pasture and is uneconomical.
