[0014] An operation method of an environmentally friendly floating box for underwater aquaculture operations in the ocean, the method steps are as follows: Step 1: First, the four pontoon panels are bolted and connected by using the tying ropes and the combination lock holes. The tying ropes have their own characteristics to reduce the possibility of breakage of the rigid connection when used on the water surface, and effectively prevent seawater erosion. Then, the positioning base is placed on the top of the pontoon panel, and the limit pin is inserted into the inner cavity of the limit plug hole. The positioning base, the support seat and the net-lifting support rod are installed and positioned, and the end of the hanging rope away from the support seat is bolted to the side of the hanging net, and the hanging net is supported by the net-lifting support rod and the hanging rope; The second step is to lift the net by hand, such as when drying the net or catching aquatic products, and then the user holds the limiting sliding sleeve and pulls it, so that the bottom end of the limiting sliding sleeve is separated from the inner cavity of the current positioning socket, and the spring is compressed at the same time, and then the limiting sliding sleeve is pushed, so that the hand lever is in the inner cavity of the arc sliding groove, so that the hand lever rotates ninety degrees, and the hand lever drives the swinging part to rotate during the rotation process, and at the same time, the connecting rod drives the sliding rod to slide upward under the rotation action of the swinging part, and the sliding rod drives the rotating frame to rotate during the sliding process, so that the rotating frame drives the pressure roller to separate from the arc limiting groove at the top of the fixed seat, and at this time, the pressure roller is separated from the extrusion limit of the hanging rope, and then the limiting sliding sleeve is released, and the spring rebounds and drives the limiting sliding sleeve to slide on the surface of the hand lever, so that the limiting sliding sleeve is engaged in the inner cavity of the current positioning socket, and the hand lever and the swinging part are limited and locked; Step 3. Next, the user shakes the crank, which drives the rotating column to rotate during the shaking process, and the rotating column drives the driving gear to rotate during the rotation process. Due to the meshing transmission of the driving gear and the force-bearing gear, the winding disk rotates, and the winding disk reels the hanging rope during the rotation process, so that the hanging rope can be pulled, and then the hanging net can be lifted. During the rotation of the rotating column, the ratchet is driven to rotate, and the ratchet is driven to turn the non-return tooth during the rotation process. The ratchet stops after rotating a certain number of turns. At this time, under the elastic force of the torsion spring, the rotating rod and the non-return tooth are released. The hand lever is rotated and the anti-return tooth is engaged with the surface of the ratchet wheel to limit and lock the ratchet wheel, thereby limiting and locking the rotating column, the driving gear, the force-bearing gear and the winding disk. At this time, the hanging net has been lifted to a certain angle, and finally the user slides the limiting sleeve again to release the limit of the hand lever, and then rotates the limiting sleeve to engage the limiting sleeve in the inner cavity of another positioning socket. During the rotation of the hand lever, the sliding rod is driven to slide through the cooperation of the swinging piece and the connecting rod, so that the rotating frame drives the pressure roller to be pressed into the arc-shaped limiting groove on the top of the fixed seat again to clamp and fix the hanging rope.

The positioning base (2), the support seat (3) and the net lifting support rod (41) are installed and positioned, and the end of the hanging rope (44) away from the support seat (3) is bolted to the side of the hanging net (45), and the hanging net (45) is supported by the net lifting support rod (41) and the hanging rope (44); Step 2: When the user needs to lift the hanging net (45), such as when drying the net or catching aquatic products, the user first holds the limiting sliding sleeve (73) and pulls it, so that the bottom end of the limiting sliding sleeve (73) is separated from the inner cavity of the current positioning socket (74), and the spring (75) is compressed at the same time. Then, the limiting sliding sleeve (73) is pushed, so that the hand rod (71) is in the inner cavity of the arc-shaped sliding groove (72), so that the hand rod (71) rotates ninety degrees. During the rotation of the hand rod (71), the swinging member (67) is driven to rotate. At the same time, the connecting rod (65) is driven by the rotation of the swinging member (67). The movable sliding rod (64) slides upward, and the sliding rod (64) drives the rotating frame (62) to rotate during the sliding process, so that the rotating frame (62) drives the pressure roller (63) to disengage from the arc-shaped limiting groove at the top of the fixed seat (61). At this time, the pressure roller (63) is separated from the extrusion limit of the hanging rope (44), and then the limiting sliding sleeve (73) is released, and the spring (75) rebounds and drives the limiting sliding sleeve (73) to slide on the surface of the hand rod (71), so that the limiting sliding sleeve (73) is engaged in the inner cavity of the current positioning socket (74), and the hand rod (71) and the swing member (67) are limited and locked; Step 3: Next, the user shakes the crank (55). The crank (55) drives the rotating column (51) to rotate during the shaking process. The rotating column (51) drives the driving gear (52) to rotate during the rotation process. Due to the meshing transmission effect of the driving gear (52) and the force-bearing gear (53), the winding disk (46) rotates. During the rotation process, the winding disk (46) winds up the hanging rope (44), so that the hanging rope (44) can be pulled, and then the hanging net (45) can be lifted. During the rotation process of the rotating column (51), the ratchet (54) is driven to rotate. During the rotation process, the ratchet (54) toggles the anti-return tooth (57). After the ratchet (54) rotates a certain number of times, it stops. At this time, under the elastic force of the torsion spring (58), the rotating rod (56) and the anti-return tooth (57) rotate. The hand lever (71) is rotated, and the anti-return tooth (57) is engaged with the surface of the ratchet (54), so that the ratchet (54) is limited and locked, thereby enabling the rotating column (51), the driving gear (52), the force gear (53) and the winding disk (46) to be limited and locked. At this time, the hanging net (45) has been lifted to a certain angle. Finally, the user slides the limiting sleeve (73) again to release the limit of the hand lever (71), and then rotates the limiting sleeve (73) to engage the limiting sleeve (73) in the inner cavity of another positioning socket (74). During the rotation process of the hand lever (71), the swinging member (67) and the connecting rod (65) are used in cooperation to drive the sliding rod (64) to slide, so that the rotating frame (62) drives the pressing roller (63) to be pressed into the arc-shaped limiting groove at the top of the fixing seat (61) again, so as to clamp and fix the hanging rope (44).
