[0020] Example: like Figures 1 to 6 As shown, this utility model provides a net cage lifting device for a deep-sea aquaculture platform, including a winch 1 and a net cage body 2. The winch 1 is mounted on the net cage body 2. The net cage body 2 includes an upper fixed ring 21, a middle fixed ring 22, a lower fixed ring 23, two net covers 24, and a net bag 25. The winch 1 is mounted on the upper surface of the upper fixed ring 21. A traction rope is wound on the winch 1. One end of the traction rope is fixedly set on the lower fixed ring 23. During the lifting process, the winch 1 rotates to wind and unwind the traction rope. When winding, the lower fixed ring 23 and the middle fixed ring 22 can be raised through the traction rope, thereby realizing the folding of the net cage. When unwinding, the middle fixed ring 22 and the lower fixed ring 23 can be lowered through the traction rope, thereby realizing the opening of the net cage. See Figure 2 and Figure 3One of the netting 24 is detachably installed between the upper fixing ring 21 and the middle fixing ring 22, and the other netting 24 is detachably installed between the middle fixing ring 22 and the lower fixing ring 23. The net bag 25 is detachably installed on the lower fixing ring 23. The overall strength of the net box can be improved by the net box composed of the upper fixing ring 21, the middle fixing ring 22, the lower fixing ring 23, the netting 24 and the net bag 25. See Figure 2 and Figure 3 The main body 2 of the net cage is provided with a guide component 3 and a fixing component 4. By setting the guide component 3, when the net cage is in the ocean or lake, the guide component 3 can guide the rising and falling net cage to avoid bending. By setting the fixing component 4, the fixing component 4 can easily fix the net 24 and the net bag 25, thereby facilitating the replacement of the net 24 and the net bag 25. See Figure 2 and Figure 3 The guide assembly 3 includes two guide rods 31. By setting two guide rods 31, the two guide rods 31 can guide the upper fixed ring 21, the middle fixed ring 22 and the lower fixed ring 23, so that the upper fixed ring 21, the middle fixed ring 22 and the lower fixed ring 23 always remain as a whole. Two ear blocks 32 are fixedly installed on the outer wall of the upper fixed ring 21, the middle fixed ring 22 and the lower fixed ring 23. One end of the guide rod 31 is fixedly provided with a threaded stud 33. Two lugs 32 are provided with threaded grooves 34. The inner walls of the threaded stud 33 and the threaded grooves 34 are rotatably connected by threads. By providing the threaded stud 33 and the threaded grooves 34, when the threaded stud 33 rotates into the interior of the threaded grooves 34, the guide rod 31 can be fixed on the upper lug 32. The other four lugs 32 are provided with through holes 35. The guide rod 31 passes through the through holes 35 and makes movable contact with the inner wall of the through holes 35. One end of the threaded stud 33 is fixedly provided with a protective cap 36. By providing through holes 35 on the four lower lugs 32, the guide rod 31 can pass through the lugs 32 without affecting the rise of the lower fixed ring 23 and the middle fixed ring 22. By providing the protective cap 36, the protective cap 36 can protect the upper end of the threaded stud 33 and prevent the threaded stud 33 from being corroded.

[0021] See Figure 5 and Figure 6The fixing component 4 includes a pressure ring 41, and several pressure rings 41 are provided. The upper fixing ring 21, the middle fixing ring 22 and the lower fixing ring 23 are all provided with pressure grooves 42 on their upper and lower surfaces. The pressure rings 41 are detachably installed in the pressure grooves 42. One end of the net 24 and the net bag 25 are detachably installed between the pressure rings 41 and the pressure grooves 42. A rubber ring 43 is fixedly provided on one side of the pressure ring 41. By setting the pressure rings 41, the pressure grooves 42 and the rubber rings 43, when the end of the net 24 or the net bag 25 is placed inside the pressure grooves 42, the net 24 or the net bag 25 can be fixed by fixing the pressure rings 41 and the rubber rings 43 in the pressure grooves 42. The net 24 or the net bag 25 can be removed by reversing the operation to remove the pressure rings 41.

[0022] See Figure 5 and Figure 6 The pressure ring 41 is provided with a plurality of slots 44 arranged in an annular array. A locking bolt 45 is rotatably installed on the inner wall of the slot 44. The inner wall of the pressure groove 42 is provided with a plurality of threaded holes 46 arranged in an annular array. One end of the locking bolt 45 is rotatably connected to the inner wall of the threaded hole 46. By setting the locking bolt 45 and the threaded hole 46, the pressure ring 41 can be fixed in the pressure groove 42 by the threaded engagement of the locking bolt 45 and the threaded hole 46. A sealing plug 47 is provided at one end of the slot 44. One end of the sealing plug 47 is interference-fitted with the inner wall of the slot 44. By setting the sealing plug 47, the sealing plug 47 can block the slot 44 and protect the locking bolt 45, preventing the locking bolt 45 from being corroded.

[0023] Working principle: When it is necessary to replace the net 24 and net bag 25, the operator first places the end of the net 24 or net bag 25 into the pressure groove 42, and then places the pressure ring 41 and rubber ring 43 into the pressure groove 42. The pressure ring 41 presses the end of the net 24 or net bag 25 into the pressure groove 42 through the rubber ring 43. Then, the locking bolt 45 is screwed into the threaded hole 46 to fix the pressure ring 41 in the pressure groove 42. When both ends of the net 24 are pressed by the pressure ring 41, the net 24 can be fixed between the upper fixing ring 21 and the middle fixing ring 22, and between the middle fixing ring 22 and the lower fixing ring 23. At the same time, the net bag 25 is fixed on the lower fixing ring 23, thus facilitating the replacement of the net 24 and net bag 25 and effectively improving the convenience of the replacement operation of the net 24 and net bag 25. By setting guide rods 31 on both sides of the upper fixing ring 21, the middle fixing ring 22 and the lower fixing ring 23, when the net cage is placed in the ocean or lake, the two guide rods 31 guide the upper fixing ring 21, the middle fixing ring 22 and the lower fixing ring 23, so that the net cage always remains as a whole and avoids the net cage from bending.
