The moving mechanism is arranged in the support tube 9, and is used to adjust the position of the fixing seat 10. The disassembly and assembly mechanism is arranged on the fixing seat 10, and is used to install and disassemble the closing ropes 11. The moving mechanism includes a threaded tube 12, a threaded column 13 and a first motor 14. The threaded tube 12 is fixedly arranged on the fixing seat 10, and the threaded column 13 is rotatably arranged on the support frame 3, wherein the threaded column 13 extends into the threaded tube 12 through threaded cooperation, and the first motor 14 is fixedly arranged on the support frame 3, and the output end of the first motor 14 is fixedly connected to the threaded column 13.

[0060] Specifically, the operator extends the screen cylinder 4 into the breeding net box body 1, and makes the support frame 3 fall into the support groove 2, so that the support shell 5 can extend into the bottom of the breeding net box body 1, and then the operator controls the first motor 14 to work. The operation of the first motor 14 can drive the threaded column 13 to rotate, and at the same time, the threaded cooperation between the threaded column 13 and the threaded tube 12 drives the fixing seat 10 to move. The movement of the fixing seat 10 can drive the closing rope 11 to pull the screen 7. In this process, the screen 7 can be moved out of the support shell 5 during the traction process and closed on the fixing seat 10. Then the operator takes the screen cylinder 4 out of the breeding net box body 1, so that the adult fish can be caught under the action of the screen 7. During the fishing process, small fish can return to the breeding net box body 1 through the sieve holes on the screen 7.

[0061] Among them, the disassembly and assembly mechanism includes a disassembly and assembly slot 15, a fixed shell 16 and a positioning mechanism.

The fixed shell 16 extends into the fixed slot through threaded cooperation. The positioning mechanism is arranged in the fixed shell 16 for positioning the relative angle between the fixed shell 16 and the fixed slot.

[0062] Specifically, in the process of the closing rope 11 pulling the screen 7, the closing rope 11 will inevitably wear against the support tube 9. During the replacement process, the operator can extend the two ends of the closing rope 11 through the disassembly and assembly slot 15 into the fixed slot and tie a knot at the two ends of the closing rope 11. Thereafter, the operator extends the fixed shell 16 into the fixed slot through threaded cooperation, and then the closing rope 11 is installed and fixed through the cooperation of the fixed shell 16 and the side wall of the fixed slot.

[0063] Among them, the positioning mechanism includes a positioning groove, a positioning block 17 and a relative movement mechanism. Two positioning grooves are respectively provided on the two opposite side walls of the fixed shell 16, the positioning groove is connected to the disassembly and assembly through groove 15, the positioning block 17 is slidably arranged in the positioning groove, and the relative movement mechanism is arranged in the fixed shell 16, for controlling the two positioning blocks 17 to move relative to each other. The relative movement mechanism includes a driving column 18, a driving disk 19, a rotating shaft and a handwheel 20. The driving column 18 is rotatably arranged on the inner bottom wall of the fixed shell 16, the driving disk 19 is fixedly arranged on the driving column 18, and two rotating shafts are rotatably arranged at the eccentric position of the driving disk 19. A positioning rod is hingedly arranged between the rotating shaft and the positioning block 17, the handwheel 20 is rotatably arranged on the fixed shell 16, and the handwheel 20 is fixedly connected to the driving column 18. It also includes a torsion spring, which is sleeved on the driving column 18, and the two ends of the torsion spring are respectively fixedly connected to the driving disk 19 and the inner bottom wall of the fixed shell 16.

[0064] Specifically, when the operator extends the fixed shell 16 into the fixed groove, the operator can turn the handwheel 20, thereby driving the driving disk 19 to rotate through the driving column 18, and then pulling the positioning block 17 back into the positioning groove through the positioning rod. After the fixed shell 16 is pressed on the closing rope 11, the operator releases the handwheel 20, so that the driving disk 19 is reset under the action of the torsion spring, so that the positioning block 17 is extended into the disassembly and assembly groove 15, so that the angle positioning of the fixed shell 16 can be achieved through the cooperation of the positioning block 17 and the disassembly and assembly groove 15, thereby preventing the fixed shell 16 from loosening in the fixed groove and affecting the installation stability of the closing rope 11.

[0065] In the present embodiment, when in use, the operator rotates the hand wheel 20, thereby driving the driving disk 19 to rotate through the driving column 18, and then pulling the positioning block 17 back into the positioning groove through the positioning rod. After that, the operator can extend the two ends of the closing rope 11 through the disassembly and assembly slot 15 into the fixed slot and tie a knot at the two ends of the closing rope 11. After that, the operator extends the fixed shell 16 into the fixed slot through threaded cooperation, and then the installation and fixation of the closing rope 11 is achieved through the cooperation of the fixed shell 16 and the side wall of the fixed slot. After that, the operator releases the hand wheel 20, so that the driving disk 19 is reset under the action of the torsion spring, so that the positioning block 17 is extended into the disassembly and assembly slot 15, so that the angle positioning of the fixed shell 16 can be achieved through the cooperation of the positioning block 17 and the disassembly and assembly slot 15, thereby preventing the fixed shell 16 from loosening in the fixed slot and affecting the closing. The installation stability of the mouth rope 11, then the operator extends the screen cylinder 4 into the breeding net box body 1, and makes the support frame 3 fall into the support groove 2, so that the support shell 5 can extend into the bottom of the breeding net box body 1, and then the operator controls the first motor 14 to work. The work of the first motor 14 can drive the threaded column 13 to rotate, and at the same time, the threaded cooperation between the threaded column 13 and the threaded tube 12 drives the fixed seat 10 to move, and the movement of the fixed seat 10 can drive the closing rope 11 to pull the screen 7. In this process, the screen 7 can be moved out of the support shell 5 during the traction process and completed on the fixed seat 10. Then the operator takes the screen cylinder 4 out of the breeding net box body 1, so that the adult fish can be caught under the action of the screen 7. During the fishing process, the small fish can return to the breeding net box body 1 through the sieve holes on the screen 7.
