In addition, automatic feeding machine and automatic net cleaning machine can be carried on I-shaped frame 21, to realize automatic feeding and automatic net cleaning function.

[0032] Net cage main body 4 is provided with arc-shaped stern at tail, and tail waterline near full load waterline is appropriately prolonged backwards, which is beneficial to reduce wave-making resistance and viscous pressure resistance. Reinforcing rod 28 and side pipe 27 form triangular stable structure at junction, to ensure the stability of net cage main body. The foam filled in main float pipe 22 can still maintain buoyancy when it is damaged, and will not be flooded. High molecular weight rope is penetrated in multiple auxiliary pipe 23, to improve the overall firmness of net cage main body.

[0033] Please refer to Figures 1-2 , four first tread plates 104 are arranged at the top of multiple steel pipes 102, fifteen water injection openings 105 are formed on the top of pedestal 101, and five water injection openings 105 are arranged on each edge of pedestal 101.

At the same time, the rubber tire 36 can buffer between the ship head structure 1 and the net cage structure 2. Through the setting of the iron sheet ring opening towards the direction of the connecting rope 31, when the net cage main body 4 drags the base 101, the connecting rope 31 is pulled tighter and tighter.

[0037] Please refer to Figures 6-7 The top of the plurality of I-shaped frames 21 on the outer side is provided with a plurality of second pedals 25, and the top of the plurality of I-shaped frames 21 on the inner side is provided with two supporting rods 29. The top of the plurality of I-shaped frames 21 on the outer side is provided with one supporting rod 29, and the inside of the plurality of supporting rods 29 is sleeved with four handrail pipes 210.

[0038] The working principle is that when a single-anchor ship type wave-damping anti-wave net cage is used, in the initial state, first, the ship head structure 1 is connected with the net cage structure 2 by sleeving the iron sheet ring 32 in the buckle ring 35, then the connecting rope 31 is sleeved on the outer surface of the iron sheet ring 32, then it is fixed through the fixing seat 33, and at the same time, the damage caused by the collision between the ship head structure 1 and the net cage structure 2 when they are subjected to wind and waves can be avoided through the rubber tire 36, then when the device is placed in the sea, 20 cubic meters of thick concrete is filled into the base 101 to play a ballast role, and in the later period, the balance can be adjusted by injecting water into the water injection port 105 according to the situation at that time, and the net cage main body 4 is used for breeding, when the device is subjected to wind and waves, when the wind and waves come, the four fishing nets 103 arranged at the bottom of the steel pipe 102 are unfolded downward and straightened, so that the waves can be blocked and buffered, and at the same time, when there is no wind and wave, the four fishing nets 103 can be rolled up, so that the impact of the wind and wave on the net cage main body 4 can be reduced, and at the same time, in order to avoid the 360° rotation of the ship head structure 1 and the net cage structure 2 caused by the wind and waves, the ship anchor 109 is pulled out to make the device deviate from the specified position, at this time, through the arrangement of the ball anchor 108, when the ship head structure 1 drives the net cage structure 2 to rotate, the ball anchor 108 can press the ship anchor 109 on the seabed, so that the ship head structure 1 and the net cage structure 2 can rotate around the ball anchor 108, and the ship anchor 109 is not pulled out, and at the same time, the anchor chain 107 can also be prevented from being knotted.

[0039] In the embodiment, the base 101 is provided with two wave instruments, nine monitoring cameras and nine warning lights to monitor the sea area condition and the real situation of the fish school.
