[0029] The truss 11 is slidably connected to the stand column 10 through a mounting seat, and a lifting mechanism is arranged between the mounting seat and the stand column 10, so as to facilitate the up-and-down movement of the truss 11 and the base frame 12 along the stand column 10, thereby adjusting the water depth position of the net cage body 1 to adapt to different breeding water areas. The impact force of wind and waves and sea currents can be dispersed to the entire frame through the hexagonal net cage body 1, the load is dispersed, the external force impact is resisted, the streamlined profile of the hexagon can guide the water flow to flow smoothly along the cage wall, reduce the vortex around the net cage body 1, and also reduce the abrasion of the net caused by the impact of the water flow. At the same time, the environment in the cage can be balanced, local dead angles can be avoided, and the breeding yield can be improved. The net cage body 1 usually includes a breeding area, a living platform 2, a bait feeding machine operation area, a monitoring equipment area and other functional modules. The staircase 3 serves as a fixed passage and can realize safe connection between regions. The staff can reach the platform 2 at the top of the net cage body 1 along the staircase 3 to assist in feeding and fish observation. The staircase 3 is connected with the truss 11 through the first telescopic sleeve 7, the connecting rod 8 and the fixed rod 9, and the first mounting block 4, the second mounting block 5 and the third mounting block 6 are installed at the connection between the truss 11 and the first telescopic sleeve 7, the connecting rod 8 and the fixed rod 9. The first mounting block 4, the second mounting block 5 and the third mounting block 6 are used to protect the outside of the first telescopic sleeve 7, the connecting rod 8 and the fixed rod 9, to strengthen the structural connection stability, prevent the staircase 3 from loosening and falling off, and to improve the stability of the connection between the staircase 3 and the net cage body 1, thereby prolonging the service life of the connecting components of the staircase 3 and the net cage body 1.

The compression spring 14 and the connecting spring are protected by the first telescopic sleeve 7 and the second telescopic sleeve 22. When the escalator 3 is impacted, the first telescopic sleeve 7 and the second telescopic sleeve 22 are contracted and press the compression spring 14 and the connecting spring, thereby buffering the force received by the escalator 3 and reducing the impact and damage of the escalator 3. At the same time, the first telescopic sleeve 7 and the second telescopic sleeve 22 can be adjusted in length by telescoping, so as to adapt to the dynamic displacement of the net cage body 1 caused by tides and wind waves. The second telescopic sleeve 22 can separate the escalator 3 from the second mounting block 5, so as to facilitate plug-in replacement. The first telescopic sleeve 7 is fixed by the limiting assembly, and the second telescopic sleeve 22 is fixed by the fixing assembly, so as to adapt to the high shaking and strong impact of the net cage body 1 in the marine environment, ensure the stable connection and safe passage of the escalator 3 in the dynamic environment, reduce the risk of component wear and fracture through the elastic structure, and significantly improve the reliability, safety and service life of the escalator 3 on the net cage body 1.

The moving plate 16 is threadedly connected on the rotating rod, and the two sides of the moving plate 16 are slidably connected with the inner wall of the mounting groove. The moving plate 16 has the pushing plate 17 hinged on both sides. One end of the pushing plate 17 is hinged with the limiting plate 18. One side of the limiting plate 18 is slidably connected with the inner wall of the mounting groove. Two movable openings are formed in the bottom of the second mounting block 5 and the top of the third mounting block 6. The limiting plate 18 has the movable rod 19 fixedly connected on the top near the two sides of the fixed rod 9. The movable rod 19 has the fixed plate 20 fixedly connected on the top and penetrating through the movable opening in the bottom of the second mounting block 5. The fixed plate 20 is slidably connected with the inner wall of the second mounting block 5 and located on both sides of the fixed rod 9 in the middle of the second mounting block 5. The fixed rod 9 and the connecting rod 8 inside the second mounting block 5 and the third mounting block 6 are both provided with limiting openings. The limiting plate 18 is plugged with the limiting openings on the connecting rod 8 inside the second mounting block 5 and the third mounting block 6. The fixed plate 20 is plugged with the limiting openings on the fixed rod 9 in the middle of the second mounting block 5.

[0033] When the escalator 3 is installed, the first telescopic sleeve 7 is connected with the connecting rod 8 and the fixing rod 9 and the escalator 3, and then the connecting rod 8 and the fixing rod 9 are installed on the net box body 1, so that the first mounting block 4, the second mounting block 5 and the third mounting block 6 are installed outside the net box body 1 of the first telescopic rod, the connecting rod 8 and the fixing rod 9, the connection between the escalator 3 and the net box body 1 is protected, then the second telescopic sleeve 22 is inserted with the second mounting block 5 and the third mounting block 6, so that the second telescopic sleeve 22 is fixed between the escalator 3 and the second mounting block 5 and the third mounting block 6, the escalator 3 is limited, the motor 15 is started to drive the rotating rod to rotate along the inner wall of the mounting groove, because the two sides of the moving plate 16 are slidingly connected with the inner wall of the mounting groove, the moving plate 16 moves along the rotating rod and pushes the push plate 17 to deflect, the push plate 17 pushes the limiting plate 18 to move along the mounting groove and is inserted with the limiting hole on the connecting rod 8 and the fixing rod 9 in the third mounting block 6, the connecting rod 8 and the fixing rod 9 are limited, when the limiting plate 18 close to the fixing rod 9 moves, the movable rod 19 moves, the movable rod 19 drives the fixed plate 20 at the top to move, so that the fixed plate 20 can be inserted with the limiting hole on the fixing rod 9 in the middle of the second mounting block 5, the fixing rod 9 in the second mounting block 5 is limited, and then the stability of the connection between the escalator 3 and the net box body 1 is improved, the escalator 3 is prevented from shaking and deforming due to impact, and the use of the escalator 3 is affected.

[0035] When the movable rod 19 moves, the baffle 21 is moved, so that the baffle 21 can be moved to the movable port to shield the movable port, prevent the impurities in the movable port from affecting the limiting effect of the limiting assembly, and facilitate to improve the stability of the escalator 3 and the net cage body 1. When the escalator 3 needs to be replaced, the motor 15 is started to drive the rotating rod to rotate, so that the moving plate 16 moves away from the motor 15, and the pushing plate 17 is deflected, so that the pushing plate 17 drives the limiting plate 18 away from the connecting rod 8 and the fixed rod 9, and is no longer inserted with the limiting port. When the limiting plate 18 in the third mounting block 6 close to the fixed rod 9 moves away from the fixed rod 9, the movable rod 19 and the baffle 21 are moved, so that the baffle 21 at both ends of the movable rod 19 moves from the movable port to the moving groove, and the fixed plate 20 is driven by the movable rod 19 to move away from the fixed rod 9 in the middle of the second mounting block 5, so that the fixed rod 9 in the middle of the second mounting block 5 is no longer limited, and the limiting assembly no longer limits the connecting rod 8 and the fixed rod 9 connected on the escalator 3. Then the second telescopic sleeve 22 is separated from the second mounting block 5 and the third mounting block 6, so that the first mounting block 4, the second mounting block 5, the third mounting block 6, the first telescopic sleeve 7, the connecting rod 8 and the fixed rod 9 are detached from the net cage body 1, so that the escalator 3 can be detached from the net cage body 1 for replacement, and the use effect of the escalator 3 is improved.

[0036] As shown in Figures 6 to 9 The fixed assembly is located on the second mounting block 5 and the third mounting block 6, and is symmetrically arranged with the first mounting block 4 and the second mounting block 5 as the center.

One side of the second tooth plate 25 is fixedly connected with the insertion block 27. The outer side of the first tooth plate 24, the gear 26, the second tooth plate 25 and the insertion block 27 is provided with a protection block 28. One side of the protection block 28 is fixedly connected with the second mounting block 5 and the third mounting block 6. The first tooth plate 24 and the second tooth plate 25 are slidably connected with one side of the second mounting block 5 and the third mounting block 6. The shape of the connecting plate 23 is L-shaped. The connecting plate 23 is located at the top of the baffle 21, and one side thereof is slidably connected with the first mounting block 4 and the second mounting block 5.

At the same time, the movable rod 19 drives the fixed plate 20 to be inserted into the limiting hole on the fixing rod 9 in the second mounting block 5, so as to limit the fixing rod 9 in the second mounting block 5. When the movable rod 19 moves, the connecting plate 23 is also moved, so that the moving plate 16 drives the first toothed plate 24 to move towards the fixing rod 9. The gear 26 drives the movable shaft to rotate along one side of the second mounting block 5 and the third mounting block 6, so that the second toothed plate 25 drives the insertion block 27 to be inserted into the second telescopic sleeve 22, thereby limiting the second telescopic sleeve 22, and the escalator 3 can be stably installed on the net box body 1.

[0038] Working principle: in use, first, the first telescopic sleeve 7, connecting rod 8, fixed rod 9 and net box body 1 are connected, so that the escalator 3 is preliminarily fixed on the net box body 1, then the first mounting block 4, the second mounting block 5, the third mounting block 6 are respectively installed on the upper end, the middle and the lower end of the escalator 3, the connection between the first telescopic sleeve 7, the connecting rod 8 and the fixed rod 9 and the net box body 1 is protected, then the second telescopic sleeve 22 is inserted with the second mounting block 5 and the third mounting block 6, so that the second telescopic sleeve 22 is fixed between the escalator 3 and the second mounting block 5 and the third mounting block 6, the escalator 3 is limited, the motor 15 drives the rotating rod to rotate along the inner wall of the installation slot, because the moving plate 16 is slidably connected on both sides of the installation slot, the moving plate 16 moves along the rotating rod and pushes the push plate 17 to deflect, the push plate 17 pushes the limiting plate 18 to move along the installation slot and inserts the limiting plate 18 into the limiting hole on the connecting rod 8 and the fixed rod 9 in the third mounting block 6, the connecting rod 8 and the fixed rod 9 are limited, when the limiting plate 18 close to the fixed rod 9 moves, the movable rod 19 moves, the movable rod 19 drives the fixed plate 20 connected at the top to move, so that the fixed plate 20 can be inserted into the limiting hole on the fixed rod 9 in the middle of the second mounting block 5, the fixed rod 9 in the second mounting block 5 is limited, when the fixed rod 9 in the third mounting block 6 is inserted into the limiting hole through the limiting plate 18, the limiting plate 18 drives the movable rod 19 and the baffle 21 to move, so that the baffle 21 moves from the moving slot to the active port, the active port is shielded, at the same time, the movable rod 19 drives the fixed plate 20 to be inserted into the limiting hole on the fixed rod 9 in the second mounting block 5, the fixed rod 9 in the second mounting block 5 is limited, when the movable rod 19 moves, the connecting plate 23 also moves, the moving plate 16 drives the first toothed plate 24 to move towards the fixed rod 9, the gear 26 drives the movable shaft to rotate along one side of the second mounting block 5 and the third mounting block 6, the second toothed plate 25 drives the plug 27 to be inserted into the second telescopic sleeve 22, the second telescopic sleeve 22 is limited, so that the escalator 3 can be stably installed on the net box body 1.

[0039] When the escalator 3 is impacted, the first telescopic sleeve 7 and the second telescopic sleeve 22 are retracted, and the compression spring 14 and the connecting spring are extruded, thereby buffering the force received by the escalator 3, reducing the impact and damage of the escalator 3. At the same time, the first telescopic sleeve 7 and the second telescopic sleeve 22 can adjust the length through telescopic adjustment, adapt to the dynamic displacement of the net box body 1 due to tides and wind waves. When the escalator 3 needs to be replaced, the motor 15 is started to drive the rotating rod to rotate, so that the moving plate 16 moves away from the motor 15, and the push plate 17 is deflected, so that the push plate 17 drives the limiting plate 18 away from the connecting rod 8 and the fixed rod 9, and is no longer inserted with the limiting port. When the limiting plate 18 in the third mounting block 6 close to the fixed rod 9 moves away from the fixed rod 9, the movable rod 19 and the baffle 21 are driven to move, so that the baffle 21 at both ends of the movable rod 19 moves from the moving port to the moving slot, and the movable rod 19 drives the fixed plate 20 away from the fixed rod 9 in the middle of the second mounting block 5, so that the fixed plate 20 is separated from the limiting port on the fixed rod 9 in the middle of the second mounting block 5, thereby the limiting assembly no longer limits the connecting rod 8 and the fixed rod 9 connected on the escalator 3.
