At present, domestic marine culture gradually tends to be more specialized and intelligent, and fishery culture and marine engineering are gradually fused together. The development of fishery breeding technology is promoted by ocean engineering technology.

With the development of marine fishery breeding technology, various breeding ships and breeding net cages appear on the market. Most of the cultivation equipment pays attention to the characteristics of wild natural environment cultivation. In the current cultivation ship, a plurality of cultivation net cages are arranged in the ship. The most serious defects of the type of aquaculture ship are that the cage culture environment at the downstream of the water flow is poor, food residues, fish feces and other garbage in the upstream cage can flow into the later cage along with the sea flow, and the cage culture environment at the later position is poor. Particularly for a catamaran, water flows on two sides of the net cage can be limited by a catamaran body, the water flows can only flow from the bow to the tail, seawater exchange cannot be carried out on the side faces of the net cage, and the culture environment is worse. Although the wild marine environment culture is pursued, the culture environment of the following net cages is worse and is not beneficial to the survival of fishes due to the common catamaran culture ship. According to the actual culture experience of the Havfarn aquaculture ship in Norway, the Havfarn aquaculture ship comprises 6 culture net cages, but the environment of the back 3 culture net cages is severe, and the fish death rate is high. Therefore, for the cultivation equipment such as cultivation ships, how to ensure equal cultivation environment in each net cage is a great cultivation problem.

One of the upper beams 112 and the lower beam 122 is located at the upper portion and the lower portion of the fore hull 2, respectively, the other of the upper beams 112 and the lower beam 122 is located at the upper portion and the lower portion of the aft hull 3, respectively, the remaining four upper beams 112 are in one-to-one correspondence with the four columns 13, and the remaining four lower beams 122 are also in one-to-one correspondence with the four columns 13.

Therefore, the breeding space of the connection frame 1 in this embodiment comprises five separate breeding areas.

A breeding net 4 is arranged in the breeding space. And a culture net 4 is arranged in each culture area.

Specifically, aquaculture net 4 includes the protection network and sets up the intranet in the protection network, and the protection network is the tortoise shell net, and the material of intranet is ultra high molecular weight polyethylene netting. The culture is located in an inner net, and the mesh of the inner net is 6cm. The protective net is used for preventing floaters, sharks and the like from damaging the inner net.

The upper floating body 11, the lower floating body 12, the upright posts 13 and the plurality of inclined struts 14 form a connecting frame 1 of a firm truss type structure. The connecting frame 1 can permeate water, so that good water permeability of a culture space is ensured, and seawater exchange is facilitated.

The structure of the connecting frame 1 enables the connecting frame to directly form a net cage with a culture space, and the culture function can be realized by arranging a double-layer culture net 4 in the culture space. Meanwhile, the upright posts 13, the upper cross beams 112 and the lower cross beams 122 of the connecting frame 1 cooperate with the culture net 4 to divide the culture space into 5 independent culture areas.

The two fore hulls 2 are arranged in parallel at intervals at the front end of the connecting frame 1. The fore-and-aft dimension of each of the header hulls 2 is larger than the left-and-right dimension, and the header hull 2 is slim. In the present application, the aspect ratio of the slender type means 2 or more, that is, the ratio of the front-rear direction dimension of the bow hull 2 to the left-right direction dimension is 2 or more.

The size of the tail ship body 3 in the front-back direction is larger than that in the left-right direction, and the tail ship body 3 is slender. That is, the ratio of the fore-and-aft dimension to the left-and-right dimension of the trailing hull 3 is 2 or more.

Ballast tanks are arranged in the head hull 2 and the tail hull 3, so that the deep and open sea aquaculture ship can float and sink by adjusting ballast water.

Namely, the deep and open sea aquaculture ship adjusts the draft of the ship body by adjusting the ballast water in the ballast tanks of the head ship body 2, the tail ship body 3, the upper tank body 111 and the lower tank body 121, thereby realizing the adjustment of the size of aquaculture water body according to the aquaculture amount.

The two head hulls 2, the two tail hulls 3 and the connecting frame 1 form the hull of the deep and open sea aquaculture ship.

Whole hull is showing through thin and long type bow part hull 2 and afterbody hull 3 and has reduced wave making resistance, has reduced the ship ripples for deep and far sea breed worker's ship's in this application navigational speed is fast, and mobility is good. Meanwhile, the boat body has a small waterplane surface due to the thin and long structure, and the wave resistance is good. The slender head hull 2 also provides a larger flow area for ocean currents, and the exchange efficiency of seawater in the culture space is ensured.

The deep and far sea cultivation ship comprises two head hulls 2 and two tail hulls 3, and is connected through a truss type water permeable connecting frame 1, so that the catamaran and the truss type sea water permeable structure are combined, and the deep and far sea cultivation ship has the performance characteristics of the catamaran and the characteristics of a sea water permeable structure.

Since the connection frame 1 is a truss structure, the fore hull 2 and the aft hull 3 distributed at four corners provide most of the buoyancy and the water plane area. When the draft height of the hull is located at the middle position between the upper floating body 11 and the lower floating body 12, only a small water plane is formed by the fore hull 2, the aft hull 3, the columns 13 and the struts 14. The design characteristic of small water plane area ensures that the deep-open sea aquaculture ship has good motion performance, and the ship body has small and stable swing.

The independent fore hull 2 and the independent aft hull 3 greatly increase the transverse inertia moment of the deep and far sea aquaculture ship on the water surface, further increase the restoring moment, have excellent stability, and the stability reserve is 2-4 times larger than that of a monohull ship in the related technology.

The two bow hulls 2 ensure good course stability and maneuverability of the cultivation vessel.

The top of the head hull 2 is provided with a mechanical area, and mechanical cabins such as a main engine room, a power distribution room, a battery room and a centralized control room are arranged in the mechanical area. The weight of the bow is greater due to the presence of the mechanical region in the bow hull 2, so that the size of the bow hull 2 in the longitudinal direction is greater than the size of the tail hull 3 in the longitudinal direction, so that the bow hull 2 provides more buoyancy.

The mechanical area is provided with an automatic fish feeding and collecting equipment room, a feeding equipment room, a feed storage room, a dead fish recovery equipment room, a dead fish crushing equipment room and the like.

The deep open sea aquaculture ship comprises two living buildings which are respectively arranged at the front end and the rear end. The head-end living building module arranged at the front end is mainly used for driving control and crew working and living areas, such as a breeding monitoring room, a driving cab, a remote control room and the like. The tail living building at the tail end is mainly a tourist entertainment area, illustratively, a sea characteristic science and technology venue such as a science and technology venue, a sea exhibition venue, a sea environmental protection education venue and the like. The top of the tail living building is also provided with a helicopter deck.

The setting of two life modules guarantees that crewman district and visitor district are effectively cut apart, guarantees visitor's safety.

Wherein, the bottom of each head hull 2 is provided with a full-rotation propeller 5, and the bottom of each tail hull 3 is provided with a full-rotation propeller 5. The full-rotation propeller 5 enables the deep and open sea cultivation ship to have navigation capability, and can shift during typhoon to avoid typhoon. The full-slewing thruster 5 can rotate the ship by 360 degrees and shift transversely, and is more flexible than a direct-pushing propeller.

Namely, the sailing and the displacement of the deep and open sea aquaculture ship are realized through the four full-rotation propellers 5.

The suction anchor 63 is pre-installed in a predetermined sea area and then the suction anchor 63 and the mooring 61 on the hull are connected by a mooring line 62. Compared with a multi-point mooring system, the single-point mooring system enables the deep and open sea aquaculture worker ship to be subjected to the minimum marine environment load, and is beneficial to ship safety and economy improvement.

The dynamic positioning system is used for driving the ship body to rotate around the suction anchor 63, so that an angle alpha is formed between the ship body of the deep and far sea culture ship and the ocean current, the seawater can flow to the culture space through the transverse direction, and the quality of seawater exchange is ensured.

Furthermore, an included angle alpha between the deep and open sea aquaculture worker ship and the direction of ocean current is 45-90 degrees.

And after the included angle alpha between the deep and open sea aquaculture worker ship and the ocean current direction reaches a preset angle, stopping the work of the dynamic positioning system. However, the deep open sea farmer ship gradually deviates from the preset angle under the wind vane effect. And at the moment, the dynamic positioning system is started again to drive the deep and open sea aquaculture ship to rotate to a preset angle. The water changing device works repeatedly, so that the aquaculture worker ship with the single-point mooring system ensures that each aquaculture area has ideal water changing efficiency.

And under the effect of the full-circle-turning propeller 5, the deep and open sea aquaculture ship can rotate around a single-point system, a good angle is provided for seawater to flow through the net cage, and seawater can be guaranteed to flow into the net cage from the transverse direction.

The deep open sea aquaculture ship comprises a crane 7 arranged on the connecting frame 1. Specifically, rails are provided on both lateral sides of the connection frame 1, each rail extending in the longitudinal direction. The crane 7 is able to slide along the rails so that the crane 7 can move back and forth between the leading end and the trailing end of the connecting frame 1, i.e. the crane 7 moves between the leading hull 2 and the trailing hull 3.

In this embodiment, the number of the hoist 7 is two, and the two hoists are arranged on both lateral sides of the connection frame 1. Namely, the two cranes 7 are arranged in one-to-one correspondence with the two rails.

The crane 7 adopts a rail moving mode, so that each breeding area can be served by the crane 7, the increase of weight and cost due to the arrangement of a plurality of cranes 7 is avoided, the weight of the whole deep and open sea breeding ship is reduced, and the cost is reduced.

The deep open sea aquaculture ship further comprises a hard wing sail 8 and a solar panel 9 arranged on the hard wing sail 8. The hard wing sail 8 provides auxiliary power for navigation of the deep sea aquaculture ship. The solar panel 9 is used for providing green electric energy.

Wherein the hard wing sail 8 is arranged in the middle area of the connecting frame 1. The middle region of the connection frame 1 does not refer to the position of the connection frame 1 at the center in the longitudinal direction, but refers to a region of a certain length range including the position of the connection frame 1 at the center in the longitudinal direction, excluding the end portions at both ends in the longitudinal direction of the connection frame 1. In this embodiment, the hard wing sail 8 is disposed on the upper beam 112.

Specifically, when the hard wing sail 8 is laid down on the connection frame 1, the solar panel 9 is located on top of the hard wing sail 8.

The solar panels 9 are installed according to the radian of the surface of the hard wing sail 8. The electric energy generated by the solar panel 9 is stored in the battery room, and the power consumption requirements of the deep and open sea aquaculture worker ship except for the propulsion system are met. Namely, when the rotary propeller works, power is supplied through the main generator set. The rest of the electricity passes through the solar panel 9.
