Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture workboats, in particular to a cruising aquaculture workboat with an open hull. Background Art

[0002] At present, there are two main forms of aquaculture on industrial vessels. One is the closed cabin aquaculture mode, which mainly uses the internal space of the ship as the aquaculture cabin. The ship is equipped with a large seawater pump for the exchange of seawater between the aquaculture cabin and the outside seawater. The other is the open cage aquaculture mode, which uses a floating frame structure to suspend the aquaculture net to form an aquaculture environment where seawater can flow naturally. The volume of aquaculture water in the first closed cabin aquaculture mode is limited by the space of the hull. The large aquaculture water volume means expensive ship construction costs, and the aquaculture water exchange relies on a large flow pump, which has a high energy consumption for daily aquaculture. The second floating cage aquaculture ship has a large aquaculture water volume and relies on the natural exchange of seawater. The daily aquaculture energy consumption is low, but the floating cage has a large water resistance and is not suitable for navigation. It is difficult to meet the needs of long-distance transfer and rapid response to typhoons and red tides, and the daily maintenance and cleaning of the cage are difficult.

[0003] Application publication number CN110214734A discloses a cruising aquaculture platform suitable for onboard shipboard aquaculture and open aquaculture at sea, wherein an open aquaculture cabin is formed by a net cage and a concave portion, the inner space of the net cage is used for aquaculture, and a closed aquaculture cabin is provided on the lower side of the hull of the concave portion, and the onboard closed cabin aquaculture mode, the onboard open net cage aquaculture mode, and a mixed mode of the first two aquaculture modes can be flexibly switched according to different working conditions;

[0004] Application publication number CN112498591A discloses a layout type aquaculture vessel, which is suitable for cruising aquaculture at sea. Within the same size range, it can achieve the largest aquaculture water body, improve the economic efficiency of large-scale aquaculture, and use the water inside and outside the cabin to automatically maintain balance, reducing the energy consumption of aquaculture water circulation;

[0005] Application publication number CN116616237A discloses an autonomous cruising aquaculture platform that can be moved to a low-latitude doldrum zone or atoll lake when a typhoon strikes;

[0006] In cruising aquaculture vessels, since the aquaculture tanks need to prevent fish from escaping, there is a lack of effective means to recycle and treat dead fish in the aquaculture tanks. They are generally left to degrade naturally or eaten by other fish. In addition, during the decay of the carcasses, water pollution is serious. A large amount of seawater is required for a large amount of water exchange to ensure the safety of the water environment in the aquaculture tanks, which leads to the need for additional exchange. In the aquaculture environment, if dead fish are not cleaned up in time, it will not only affect the water quality, but may also spread diseases to other healthy fish. How to thoroughly clean the cages is crucial to maintaining the health of the aquaculture environment.

[0007] The above-mentioned prior art is troublesome to clean the cages. Although the environment inside the cages is relatively improved, it cannot be repeatedly contacted with open water, and the breeding density is still very high. When the wind and waves impact the breeding cabin, it is easy to scare the fish in the breeding cabin, and it is impossible to carry out decentralized breeding that completely simulates the open water environment. It overcomes the shortcomings of existing closed cabin breeding ships and floating cage breeding ships and meets production requirements. Utility Model Content

[0008] In view of this, facing the shortcomings of the prior art, the purpose of the utility model is to provide a cruising aquaculture workboat with an open hull, which overcomes the shortcomings of the existing closed cabin aquaculture workboat and floating cage aquaculture workboat, and the aquaculture cabin is lifted, so that the workboat can sail normally and quickly transfer; the workboat is equipped with a downwardly extending aquaculture cabin. When aquaculture is carried in a fixed sea area, the aquaculture cabin is arranged within the framework of the open hull structure, which is used for free exchange with seawater, so as to realize open aquaculture and save corresponding aquaculture energy consumption; when it is necessary to transfer, or avoid typhoons and red tides, when the aquaculture ship needs to transfer, the aquaculture cabin is retracted upward into the hull, which does not affect normal navigation, reduces navigation resistance, and avoids disturbing the fish school by navigation. When the aquaculture cabin needs to be repaired and cleaned, the walking hoisting mechanism installed on the hull is used to lift the aquaculture cabin as a whole above the water surface, and necessary repairs and cleaning are carried out. The periphery of each aquaculture cabin is protected by the double side shells, double-layer middle longitudinal bulkheads, and double-layer transverse bulkheads, so that the lateral impact of daily waves is avoided through the aquaculture cabin;

[0009] When cleaning the aquaculture cabin of the present application, the walking hoisting mechanism installed on the hull is used to lift the aquaculture cabin as a whole above the water surface, which can ensure the complete and thorough cleaning of the dead fish remains in the aquaculture cabin and ensure the health of the environment in the aquaculture cabin;

[0010] The present application aims to solve one of the problems in the background technology. The technical solution adopted by the present utility model is to provide the following technical solutions to achieve the above-mentioned purpose and other related purposes:

[0057] Specifically, in one embodiment of the present application, the front and rear parts of the hull 7 are respectively provided with a living cabin, a working cabin, a cab, a cabin 9, a propeller 10, and a steering gear 11, and the middle part of the hull 7 is a breeding area; a track 6 is provided on the upper end surface of the double side 2 and the double-layer middle longitudinal bulkhead 3. At least one walking hoisting mechanism 5 is provided on the track 6, and the hoisting mechanism 5 moves forward and backward along the track 6 to the upper position of a single breeding cabin 1 to lift the breeding cabin 1. The double-layer middle longitudinal bulkhead 3 and the double-layer transverse bulkhead 4 are watertight structures for providing buoyancy for the breeding work boat. The double-layer middle longitudinal bulkhead 3 and the double-layer transverse bulkhead 4 are arranged horizontally and vertically. A seawater ballast pipeline is arranged inside the hull 7 for adjusting the seawater ballast to control the draft and buoyancy of the work boat.

[0058] Specifically, in one embodiment of the present application, the present case can be implemented in this way to realize a cruising aquaculture vessel with an upper and lower open hull that can sail normally. The vessel is a steel monohull 7 with continuous side, and the living cabin, working cabin and driving cabin are located in the superstructure 8 at the front of the vessel. The ship engine room 9 is located at the rear of the hull 7, and is equipped with a ship propeller 10 main engine and a ship power station. The ship is propelled by a propeller, and a rudder is installed at the rear of the propeller. The middle of the hull 7 is used as a breeding area;

[0059] The aquaculture area in the middle of the hull 7 is designed as an open hull structure type, without a bottom and a deck, and the aquaculture area is openly connected to the seawater outside the ship. The open hull structure consists of double side shells 2, double-layer middle longitudinal bulkheads 3, and double-layer transverse bulkheads 4, forming a stable frame structure, providing the necessary overall strength for the aquaculture ship.

[0060] Specifically, in one embodiment of the present application, the double side shell 2, the double-layered middle longitudinal bulkhead 3, and the double-layered transverse bulkhead 4 are watertight structures, which are used to provide necessary buoyancy for the aquaculture vessel.

[0061] Specifically, in one embodiment of the present application, seawater ballast pipelines are arranged inside the double side shells 2, the double-layer middle longitudinal bulkhead 3, and the double-layer transverse bulkhead 4, and the draft and buoyancy of the work vessel can be controlled by adjusting the seawater ballast.

[0062] Specifically, in one embodiment of the present application, the breeding cabin 1 is installed in a structural frame of a hull 7 that is open at the top and bottom, and the bottom of the hull 7 is completely open. The breeding cabin 1 is used to freely exchange with seawater to save corresponding breeding energy consumption; the periphery of each breeding cabin 1 is protected by the double side hull 2, the double-layer middle longitudinal bulkhead 3, and the double-layer transverse bulkhead 4, and the lateral impact of daily waves is avoided through the breeding cabin 1.

[0063] Specifically, in one embodiment of the present application, a longitudinal traveling and lifting mechanism 5 is installed on the hull 7, and the traveling and lifting mechanism 5 moves forward and backward along the track 6 installed on the hull 7 to a position above a single breeding cabin 1, so as to perform operations such as lifting the breeding cabin 1, and realize daily maintenance, repair and cleaning of the breeding cabin 1.

During breeding, the breeding cabin 1 extends downward from below the hull 7 to expand the volume of the breeding water body; when it is necessary to transfer, the breeding cabin 1 is retracted upward to within the hull 7, which does not affect normal navigation, reduces navigation resistance, and avoids disturbing the fish school during navigation; when the breeding cabin 1 needs to be repaired and cleaned, the traveling crane mechanism 5 installed on the hull 7 is used to lift the breeding cabin 1 as a whole above the water surface for maintenance and cleaning.

[0065] A method for using an open-hull cruising aquaculture vessel, comprising using any of the open-hull cruising aquaculture vessels described herein, the method comprising the following steps:

[0066] S1. Place a group of breeding cabins 1 in the wall-type structural space between the double-layer middle longitudinal bulkhead 3 and the double-layer transverse bulkhead 4;

[0067] S2. During aquaculture, the aquaculture cabin 1 extends downward from the hull 7 to expand the aquaculture water volume;

[0070] The aquaculture boat in this example has a lower total capacity of the ship power station due to its low aquaculture energy consumption; the power configuration of the ship propulsion system is reduced due to its low navigation resistance; and the smaller hull size is adopted due to the expansion of the aquaculture water body, which is conducive to saving the ship construction cost. Under the condition of equivalent aquaculture water body, the aquaculture boat in this example has significantly lower ship construction cost and operation cost compared with the closed aquaculture boat; the aquaculture boat in this example has better navigation maneuverability compared with the truss cage aquaculture boat.

[0071] The utility model aims to solve the problems of existing aquaculture vessels in terms of aquaculture energy consumption, navigation resistance, ship construction cost and operating cost. By designing a cruising aquaculture vessel with an open hull, the middle part of the vessel is a frame-type structure that is open up and down, and can be installed with a telescopic aquaculture cabin, so that the aquaculture cabin and seawater can be freely exchanged, thereby saving aquaculture energy consumption. The aquaculture cabin can be retracted upward into the hull during transfer, reducing navigation resistance and avoiding disturbing the fish school. When maintenance and cleaning are required, the aquaculture cabin can be lifted above the water surface by a walking lifting mechanism for easy operation and maintenance. Through such a design, the total capacity of the ship's power station can be significantly reduced, the power demand of the ship's propulsion system can be reduced, and the hull size can be reduced, thereby saving construction costs and operating costs. Compared with truss cage aquaculture vessels, it has better navigation maneuverability.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, at least one improvement and replacement can be made without departing from the technical principle of the present invention. These improvements and replacements should also be regarded as the protection scope of the present invention.
