Deep and far sea culture work ship based on wind energy-wave energy combined power generation and single point mooring

Abstract

The invention relates to a deep and far sea culture work ship based on wind energy-wave energy combined power generation and single-point mooring. The deep and far sea culture work ship comprises a bow, a stern and a plurality of culture net cages arranged between the bow and the stern. The stem is provided with an inner turret single-point mooring system, the inner turret single-point mooring system comprises a moon pool arranged on the stem and a buoy located in the moon pool, and the stem is rotationally connected with the buoy; a wind driven generator is installed above a deck of the stern, and a wave power generation device is installed below the deck. The wave energy power generation device is arranged at the stern, heaving motion response of the oscillating floaters is increased, power generation efficiency is improved, and meanwhile heaving and pitching motion response of the breeding work ship can be reduced through the damping effect of the oscillating floaters; the horizontal shaft fan is arranged at the stern, so that the gravity center of the ship body moves backwards, the single-point mooring weather vane effect of the whole ship can be enhanced, the seawater exchange rate can be increased, meanwhile, the good windward posture of the fan can be kept, high-power-generation-efficiency work can be conducted, and the intermittent defect of wave energy power generation is overcome.

Description

Technical field [0001] The invention belongs to the technical field of breeding work boats, and specifically relates to a breeding work ship that is suitable for deep-sea farming and adopts wind energy-wave energy combined power generation and single-point mooring. Background technique [0002] Compared with traditional shallow sea and offshore aquaculture, deep sea aquaculture has irreplaceable advantages in economic, social and environmental benefits. Therefore, it will be an inevitable trend for the aquaculture industry to move into the deep sea. The development of the aquaculture industry in the deep sea is of great strategic significance for my country's food security, fishery economy and diversified development of deep sea resources. [0003] The existing breeding ship technology has the problem of relying on land-based energy supply. In response to this problem, Chinese patent CN113460254A discloses an energy-self-sufficient modular breeding ship, which can effectivel...

Problems solved by technology

[0003] The existing technology of aquaculture workboats has the problem of relying on land energy supply. To solve this problem, Chinese patent CN113460254A discloses an energy self-sufficient modularized aquaculture workship, which can effectively solve the problem of energy self-sufficiency in aquaculture workboats. However, the patent There are the following disadvantages: (1) The wave energy generation device is close to the single-point mooring point, and the heave motion response is not significant enough; (2) The center of gravity of the whole ship is located forward, and the wind vane effect is not significant; (3) The wave energy generation is intermittent , the power generation efficiency is unstable
