[0024] The working principle of the fishing boat involved in the scheme is as follows: When the ship body 1 drives to the fishing water area, the steel cables 29 on both sides are released under the operation of the winding device 28, so that the fishing mechanism moves downward to the water area at the preset depth.

[0025] When the fishing operation is carried out in the water area of the preset depth, the plurality of sealing plates 14 are in the horizontal state, so that the first sealing ring 13 is in the open state, and the fish school is fished. With the movement of the ship body 1, the fish school in front of the cage 2 enters the cage 2 through the gap between the plurality of sealing plates 14, and the fishing is realized. At the same time, the plurality of fish attracting lamp devices 4 are turned on to attract the fish school. The cage 2 moves with the ship body 1, so that the water flow impacts the turbine 10 to rotate. The turbine 10 drives the lead screw 8 to rotate. Under the drive of the reciprocating thread, the sliding block 12 moves back and forth, driving the fish suction pump 5 to move back and forth. The suction end of the fish suction pump 5 moves along the fish attracting lamp device 4, sucks the fish school attracted by the fish attracting lamp device 4, and then discharges into the guide pipe 6 through the conveying pipe 7. Finally, the fish school is transported to the first sealing ring 13 front side port through the guide pipe 6 and enters the cage 2.

[0026] Under the cooperation of the fish suction mechanism, the fish school that misses the input port of the front end of the cage 2 can be transported in time to move to the front end of the cage 2 again, so that the fish school is fished again in a short time, improving the fishing efficiency.

[0027] In the process of moving fishing, the water body flows into the cage at the front end of the cage 2, and the water body flows backward to impact the impeller 22 to rotate. The impeller 22 drives the cage 2 to rotate through the second sealing ring 20. The cage 2 drives the plurality of guide plates 25 located in the cage 2 to rotate. The guide plates 25 press water into the cage 2, which can impact the fish school in the cage 2, reduce the contact between the fish school in the cage 2 and the inner wall of the cage 2, and reduce the damage.

[0028] In the process of rotating the cage 2, the mesh cylinder 27 is driven to rotate, which is beneficial to the volatilization of the bait in the mesh cylinder 27. In cooperation with the fish attracting lamp device 4, the fish school that misses the entrance of the front end of the cage 2 is more attracted to gather outside the cage 2, so that the fish suction pump 5 can fully guide and transport, and further facilitate the secondary fishing in a short time.

[0029] After the fishing operation is completed, the motor 16 is started to drive the transmission shaft 19 to rotate. The transmission shaft 19 drives the plurality of first gears 17 to rotate. The first gears 17 drive the corresponding shafts 15 to rotate through the plurality of second gears 18, so that the plurality of sealing plates 14 are synchronously deflected. The input end in the first sealing ring 13 is blocked to avoid the fish and shrimp that have entered the net from flowing out when the net is lifted.

[0030] After the fishing operation is completed, the net lifting operation is carried out. The winding device 28 starts to wind the steel cable 29. After the cage 2 rises to the side of the ship body 1, the two lifting eyes 3 are respectively clamped into the side of the two trusses 31. The power device 35 is started to drive the main shaft 34 to rotate. The main shaft 34 drives the two trusses 31 to deflect, so that the trusses 31 drive the cage 2 to overturn to the upper side of the ship body 1. The two cages 2 are synchronously operated. Then the lock catch device 24 is opened, the second sealing ring 20 is opened, the rear end of the cage 2 is communicated, the fished fish and shrimp are unloaded, and the fishing operation is completed.

[0031] While embodiments of the application have been shown and described, it is to be understood that the application is not limited to the details of the embodiments described, since numerous changes, modifications, substitutions and variations can be made thereto without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
