[0002] As a kind of deep-sea aquaculture equipment with self-propulsion capability, aquaculture vessels are currently the main development. They can sail to suitable sea areas for aquaculture according to the types of aquaculture products, and can take emergency evacuation measures according to the typhoon forecast path. At present, aquaculture vessels are mainly divided into closed aquaculture vessels and open aquaculture vessels. Closed aquaculture vessels use a completely closed hull, which has good wind and wave resistance and fast self-propulsion transfer speed. However, the internal closed aquaculture cabin needs to be installed with an exchange water system to frequently exchange water and discharge aquaculture wastewater to ensure the survival and good growth of aquaculture products. This process consumes more energy and increases operating costs. The open aquaculture vessel sets several large truss-type open openings in the middle section of the side to facilitate exchange with seawater at any time, saving energy while the open aquaculture environment is more conducive to the growth of aquaculture products, but its open opening increases the hull resistance during self-propulsion transfer, affecting the transfer speed.

[0028] As a kind of deep-sea aquaculture equipment with self-propulsion capability, aquaculture vessels are currently the main development. They can sail to suitable sea areas for aquaculture according to the types of aquaculture products, and can avoid typhoons according to the typhoon forecast path. At present, aquaculture vessels are mainly divided into closed aquaculture vessels and open aquaculture vessels. Closed aquaculture vessels use a completely closed hull, which has good wind and wave resistance and fast self-propulsion transfer speed. However, the internal closed aquaculture cabin needs to be installed with an exchange water system to frequently exchange water and discharge aquaculture wastewater to ensure the survival and good growth of aquaculture products. This process consumes more energy and increases operating costs. The open aquaculture vessel sets several large truss-type open openings in the middle section of the side to facilitate exchange with seawater at any time, saving energy while the open aquaculture environment is more conducive to the growth of aquaculture products, but its open opening increases the hull resistance during self-propulsion transfer, affecting the transfer speed.

[0029] The present invention provides a farming vessel 100 with a roller shutter type side opening and closing.

[0030] See also Figures 1 to 4 In one embodiment of the present invention, the roller shutter type aquaculture vessel 100 with side opening and closing includes a hull 1 and a roller shutter assembly 2. A breeding cabin 11 is provided inside the hull 1, and an opening 12 connected to the breeding cabin 11 is provided on the side of the hull 1; a receiving cavity 21 is provided on the top of the side of the hull 1, and the receiving cavity 21 is connected to the opening 12. The roller shutter assembly 2 is arranged in the receiving cavity 21. The roller shutter assembly 2 includes a first driving member 22, a drum 23 and a roller shutter piece 24. The first driving member 22 is connected to the drum 23 by transmission. A guide rail 121 extending vertically is installed on the side wall of the opening 12. The roller shutter piece 24 is wound on the drum 23. The first driving member 22 is used to drive the drum 23 to rotate, so as to drive the roller shutter piece 24 to extend into the opening 12 along the guide rail 121 and block the opening 12; or drive the roller shutter piece 24 to be retracted into the receiving cavity 21 and open the opening 12.

[0031] In the technical solution of this embodiment, the bow and stern of the roller shutter type side-opening and closing aquaculture vessel 100 can be a ship-shaped structure, such as Figure 1 As shown. The roller shutter type side opening and closing aquaculture vessel 100 comprises a hull 1 and a roller shutter assembly 2. A breeding cabin 11 is arranged inside the hull 1. The ship can be a truss structure. The top and the side of the ship can be provided with a plurality of openings connected to the internal breeding cabin 11. The side refers to the side part of the hull 1, that is, the left and right sides of the hull 1. In this embodiment, the first driving member 22 drives the drum 23 and drives the roller shutter piece 24 to block or open the opening 12 to adapt to different navigation conditions of the roller shutter type side opening and closing aquaculture vessel 100.

[0032] In the technical solution of the above embodiment, the opening 12 of the aquaculture vessel 100 with roller shutter-type side opening and closing is in an open state under aquaculture conditions to allow the seawater and the aquaculture chamber 11 to communicate with each other, so that the aquaculture water in the aquaculture chamber 11 can self-circulate with the changes in seawater, thereby reducing the energy consumption of the water exchange system and reducing operating costs. When it is necessary to transfer aquaculture or to urgently avoid a typhoon, the first driving member 22 arranged in the accommodating chamber 21 on the top of the side of the hull 1 drives the drum 23 to rotate, and the shutter piece 24 is wound around the drum 23. When the drum 23 rotates, the drum 23 drives the shutter piece 24 to extend downward along the guide rail 121 formed by the side wall of the opening 12 until the shutter piece 24 blocks the opening 12, thereby reducing the resistance of the aquaculture ship 100 with roller shutter type side opening and closing during navigation, thereby increasing the speed of the aquaculture ship 100 with roller shutter type side opening and closing, reducing fuel consumption, and facilitating the aquaculture ship 100 with roller shutter type side opening and closing for transfer of aquaculture or emergency avoidance of typhoons. When the aquaculture vessel 100 with roller shutter-type side opening and closing sails to a suitable aquaculture position, the first driving member 22 drives the drum 23 to rotate, so that the drum 23 drives the roller shutter piece 24 to rise along the guide rail 121, and retracts the roller shutter piece 24 into the accommodating chamber 21, so that the opening 12 is in an open state, thereby realizing the circulation of water and seawater in the aquaculture cabin 11.
