[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a truss-type liftable wind and wave resistant deep-sea aquaculture cage, such as Figures 1 to 5 As shown, it includes a net box body 1, which is hexagonal in shape. Two platforms 2 are fixedly installed at the bottom of the net box body 1. The net box body 1 includes columns 10, trusses 11 and a bottom frame 12. Columns 10 are provided between adjacent trusses 11. The bottom ends of the columns 10 are fixedly connected with pile shoes 13. The bottoms of the trusses 11 are fixedly connected with the bottom frame 12. The top of the net box body 1 is fixedly connected with two platforms 2. Two escalators 3 are provided on the outside of the net box body 1. A support and protection device is provided on the escalator 3. The support and protection device includes a first mounting block 4, a second mounting block 4, and a second mounting block 4. Block 5, the third mounting block 6, the first telescopic sleeve 7, the connecting rod 8, the fixed rod 9 and the limiting component, the first mounting block 4, the second mounting block 5 and the third mounting block 6 are all fixedly connected to one side of the cage body 1, the escalator 3 is fixedly connected with the first telescopic sleeve 7, the first telescopic sleeve 7 located on the left and right sides of the escalator 3 is fixedly connected with the connecting rod 8 on one side, the first telescopic sleeve 7 located in the middle of the escalator 3 is fixedly installed with the fixing rod 9, the connecting rod 8 and the fixing rod 9 are all fixedly connected to the cage body 1, the third mounting block 6 is provided with a mounting groove, and a limiting component is arranged in the mounting groove.

[0018] The truss 11 is slidably connected to the column 10 through a mounting seat, and a lifting mechanism is provided between the mounting seat and the column 10, so that the truss 11 and the base frame 12 can be moved up and down along the column 10, thereby adjusting the water depth position of the cage body 1 to adapt to different aquaculture waters. The hexagonal cage body 1 can disperse the impact of wind, waves and currents to the entire frame, disperse the load, and resist external force impact. The hexagonal streamlined profile can guide the water to flow smoothly along the box wall, reduce the generation of eddy currents around the cage body 1, and reduce the wear of the net caused by the impact of water flow. At the same time, it can balance the environment inside the box, avoid local dead corners, and improve aquaculture production. The cage body 1 usually includes multiple functional modules such as aquaculture area, living platform 2, feeding machine operation area, monitoring equipment area, etc., and the escalator 3 is used as a fixed channel. It can achieve safe connection between various areas. The staff can reach the platform 2 on the top of the cage body 1 along the escalator 3 to assist in feed delivery and fish observation. The escalator 3 is connected to 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, strengthen the structural connection stability, prevent the escalator 3 from loosening and falling off, and limit the connecting rod 8 and the fixed rod 9 through the limiting component to improve the stability of the connection between the escalator 3 and the cage body 1, thereby extending the service life of the connection parts of the escalator 3 and the cage body 1.

[0019] like Figures 3 to 6 As shown, the second mounting block 5 is located in the middle of the first mounting block 4 and the third mounting block 6, the connecting rod 8 is located at the internal ends of the first mounting block 4, the second mounting block 5 and the third mounting block 6, the fixing rod 9 is located in the middle of the second mounting block 5, and a compression spring 14 is provided in the first telescopic sleeve 7. One end of the compression spring 14 is fixedly connected to the escalator 3, and the other end is fixedly connected to the inner wall of the telescopic end of the first telescopic sleeve 7. A second telescopic sleeve 22 is provided between the second mounting block 5, the third mounting block 6 and the escalator 3. One side of the second telescopic sleeve 22 is fixedly connected to the escalator 3, and the other side is plugged into the first mounting block 4 and the second mounting block 5. A connecting spring is fixedly connected to the inside of the second telescopic sleeve 22, and one end of the connecting spring is fixedly connected to the escalator 3. A fixing component is provided between one side of the second telescopic sleeve 22 and the movable rod 19.

[0020] The first mounting block 4, the second mounting block 5 and the third mounting block 6 can evenly distribute the force on the escalator 3 to different positions of the cage body 1, so as to avoid deformation or breakage of the cage body 1 frame or the escalator 3 connection parts caused by excessive force on a single point. The compression spring 14 and the connection 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 the compression spring 14 and the connection spring are squeezed, thereby buffering the force on the escalator 3, reducing the impact and damage to the escalator 3. At the same time, the first telescopic sleeve 7 and the second telescopic sleeve 22 are used to protect the compression spring 14 and the connection spring. The retractable sleeve 22 can be adjusted in length by telescoping to adapt to the dynamic displacement of the cage body 1 caused by tides and wind and waves. By plugging in the second telescopic sleeve 22, the escalator 3 can be separated from the second mounting block 5, which is convenient for plugging and replacement. The first telescopic sleeve 7 is fixed by a limiting component and the second telescopic sleeve 22 is fixed by a fixing component. It adapts to the high shaking and strong impact of the cage body 1 in the marine environment, ensuring the stable connection and safe passage of the escalator 3 in a dynamic environment, and reducing the risk of component wear and breakage through the elastic structure, thereby significantly improving the reliability, safety and service life of the escalator 3 on the cage body 1.

[0021] like Figures 4 to 7 As shown, there are two groups of limiting components, and the two groups of limiting components are symmetrically arranged with the center of the third mounting block 6. The limiting components include a motor 15, a rotating rod, a movable plate 16, a pushing plate 17 and a limiting plate 18. The motor 15 is fixedly connected in the mounting groove, one end of the rotating rod is fixedly connected to the output end of the motor 15, and the other end is rotatably connected to the inner wall of the mounting groove. The movable plate 16 is threadedly connected to the rotating rod, and both sides of the movable plate 16 are slidably connected to the inner wall of the mounting groove. Both sides of the movable plate 16 are hinged with a pushing plate 17, and one end of the pushing plate 17 is hinged with a limiting plate 18. One side of the limiting plate 18 is slidably connected to the inner wall of the mounting groove. The bottom of the second mounting block 5 is connected to the third mounting block 6. Two movable openings are provided at the top. The top of the limiting plate 18 near both sides of the fixed rod 9 is fixedly connected to a movable rod 19. The top of the movable rod 19 passes through the movable opening at the bottom of the second mounting block 5 and is fixedly connected to a fixed plate 20. The fixed plate 20 is slidably connected to the inner wall of the second mounting block 5. The fixed plate 20 is located on both sides of the fixed rod 9 in the middle of the second mounting block 5. Limiting openings are provided on the fixing rod 9 and the connecting rod 8 inside the second mounting block 5 and the third mounting block 6. The limiting plate 18 is plugged into the limiting opening on the connecting rod 8 located in the second mounting block 5 and the third mounting block 6, and the fixing plate 20 is plugged into the limiting opening on the fixing rod 9 located in the middle of the second mounting block 5.

[0022] When installing the escalator 3, the first telescopic sleeve 7 is connected to the connecting rod 8 and the fixed rod 9 and the escalator 3, and then the connecting rod 8 and the fixed rod 9 are installed on the cage body 1, so that the first mounting block 4, the second mounting block 5 and the third mounting block 6 are installed on the outside of the cage body 1 of the first telescopic rod, the connecting rod 8 and the fixed rod 9, and the connection between the escalator 3 and the cage body 1 is protected. Then the second telescopic sleeve 22 is plugged into 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 to limit the escalator 3. The motor 15 is started to drive the rotating rod to rotate along the inner wall of the installation groove. Since the two sides of the movable plate 16 are slidably connected to the inner wall of the installation groove, the escalator 3 is The movable plate 16 moves along the rotating rod and then pushes the pushing plate 17 to deflect. The pushing plate 17 pushes the limiting plate 18 to move along the mounting groove and is plugged into the limiting openings on the connecting rod 8 and the fixed rod 9 inside the third mounting block 6, thereby limiting the connecting rod 8 and the fixed rod 9. When the limiting plate 18 close to the fixed rod 9 moves, it drives the movable rod 19 to move, so that the movable rod 19 drives the fixed plate 20 connected at the top to move, so that the fixed plate 20 can be plugged into the limiting opening on the fixed rod 9 in the middle of the second mounting block 5, thereby limiting the fixed rod 9 in the second mounting block 5, thereby improving the stability of the connection between the escalator 3 and the cage body 1, preventing the escalator 3 from shaking and deformation due to impact, affecting the use of the escalator 3.

[0023] like Figures 5 to 7 As shown, baffles 21 are fixedly connected to the upper and lower ends of the movable rod 19, a movable groove is opened on the inner wall of the movable opening, and the baffle 21 is located in the movable opening. The baffle 21 is slidably connected to the movable groove and the inner wall of the movable opening.

[0024] When the movable rod 19 moves, it drives the baffle 21 to move, so that the baffle 21 can move to the movable opening, block the movable opening, prevent impurities from falling into the movable opening and affecting the limiting effect of the limiting component, which is not convenient for improving the stability of the connection between the escalator 3 and the cage body 1. When the escalator 3 needs to be replaced, the rotating rod is driven to rotate by starting the motor 15, so that the movable plate 16 moves in the direction away from the motor 15, and pushes the pushing plate 17 to deflect, so that the pushing plate 17 drives the limiting plate 18 away from the connecting rod 8 and the fixed rod 9, and no longer connects with the limiting opening. When the limiting plate 18 close to the fixed rod 9 in the third mounting block 6 moves in the direction away from the fixed rod 9, it drives the movable rod 19 and the baffle 21 moves, so that the baffles 21 at the upper and lower ends of the movable rod 19 move from the movable mouth to the movable groove, and at the same time the movable rod 19 drives the fixed plate 20 away from the fixed rod 9 in the middle of the second mounting block 5, and no longer limits the fixed rod 9 in the middle of the second mounting block 5, so that the limiting component no longer limits the connecting rod 8 and the fixed rod 9 connected to the escalator 3, and 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 removed from the cage body 1, so that the escalator 3 can be removed from the cage body 1 for replacement, so as to improve the use effect of the escalator 3.

[0025] like Figures 6 to 9 As shown, the fixing 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. The fixing assembly includes a connecting plate 23, a first tooth plate 24, a second tooth plate 25, a gear 26 and an insert block 27. One end of the connecting plate 23 is fixedly installed with the movable rod 19, and the other end is fixedly installed with the first tooth plate 24. One side of the first tooth plate 24 is engaged with a gear 26. A movable shaft is fixedly installed in the middle of the gear 26. One side of the movable shaft is rotatably connected to the second mounting block 5 and one side of the third mounting block 6. One side of the gear 26 is engaged with the second tooth plate 25. A plug block 27 is fixedly connected to one side of the tooth plate 25, and a protective block 28 is provided on the outside of the first tooth plate 24, the gear 26, the second tooth plate 25 and the plug block 27. One side of the protective block 28 is fixedly connected to the second mounting block 5 and the third mounting block 6. The first tooth plate 24 and the second tooth plate 25 are both slidably connected to 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 to the first mounting block 4 and the second mounting block 5. A slot is provided on the side of the second telescopic sleeve 22 close to the protective block 28, and the plug block 27 is plugged into the slot.

[0026] The first tooth plate 24, the gear 26 and the second tooth plate 25 can be protected by the protective block 28 to prevent the first tooth plate 24, the gear 26 and the second tooth plate 25 from being damaged by collision, thereby affecting the effect of fixing the second telescopic sleeve 22. When the escalator 3 needs to be installed, the first telescopic sleeve 7, the connecting rod 8 and the fixing rod 9 are first connected to the cage body 1, so that the escalator 3 is initially fixed on the cage body 1, and then the first mounting block 4, the second mounting block 5 and the third mounting block 6 are respectively installed at the upper end, middle end and lower end of the escalator 3, and the connection between the first telescopic sleeve 7, the connecting rod 8 and the fixing rod 9 and the cage body 1 is protected, and then the second telescopic sleeve 22 is plugged into the second mounting block 5 and the third mounting block 6, and then the connecting rod 8 and the fixing rod 9 inside the third mounting block 6 are limited by starting the limiting component. When the fixed rod 9 in the third mounting block 6 is plugged into the limiting opening 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 movable groove to the movable opening to block the movable opening. At the same time, the movable rod 19 drives the fixed plate 20 to plug into the limiting opening on the fixed rod 9 in the second mounting block 5 to limit the fixed rod 9 in the second mounting block 5. When the movable rod 19 moves, it also drives the connecting plate 23 to move, so that the movable plate 16 drives the first tooth plate 24 to move in the direction of the fixed rod 9, so that 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 tooth plate 25 drives the plug block 27 to plug into the second telescopic sleeve 22 to limit the second telescopic sleeve 22, thereby enabling the escalator 3 to be stably installed on the cage body 1.

[0027] Working principle: When in use, first connect the first telescopic sleeve 7, connecting rod 8, fixing rod 9 and cage body 1, so that the escalator 3 is initially fixed on the cage body 1, and then install the first mounting block 4, the second mounting block 5, and the third mounting block 6 on the upper end, middle part and lower end of the escalator 3 respectively, and protect the connection between the first telescopic sleeve 7, connecting rod 8 and fixing rod 9 and cage body 1, and then plug the second telescopic sleeve 22 with the second mounting block 5 and the third mounting block 6, so that the second telescopic sleeve 22 is fixed on the escalator 3 and the second mounting block 5. Between the third mounting blocks 6, the escalator 3 is limited. The starting motor 15 drives the rotating rod to rotate along the inner wall of the mounting groove. Since the two sides of the movable plate 16 are slidably connected with the inner wall of the mounting groove, the movable plate 16 moves along the rotating rod and then pushes the push plate 17 to deflect. The push plate 17 pushes the limiting plate 18 to move along the mounting groove and plugs into the limiting openings on the connecting rod 8 and the fixed rod 9 inside the third mounting block 6 to limit the connecting rod 8 and the fixed rod 9. When the limiting plate 18 close to the fixed rod 9 moves, it drives the movable rod 19 moves, so that the movable rod 19 drives the fixed plate 20 connected at the top to move, so that the fixed plate 20 can be plugged into the limiting opening on the fixed rod 9 in the middle of the second mounting block 5, and the fixed rod 9 in the second mounting block 5 is limited. When the fixed rod 9 in the third mounting block 6 is plugged into the limiting opening 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 movable groove to the movable opening to block the movable opening. At the same time, the movable rod 19 drives the fixed plate 20 to plug into the limiting opening on the fixed rod 9 in the second mounting block 5, and the fixed rod 9 in the second mounting block 5 is limited. When the movable rod 19 moves, it also drives the connecting plate 23 to move, so that the movable plate 16 drives the first tooth plate 24 to move toward the direction of the fixed rod 9, so that 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 tooth plate 25 drives the plug block 27 to plug into the second telescopic sleeve 22, and the second telescopic sleeve 22 is limited, so that the escalator 3 can be stably installed on the cage body 1.

[0028] When the escalator 3 is impacted, the first telescopic sleeve 7 and the second telescopic sleeve 22 are contracted, and the compression spring 14 and the connecting spring are squeezed, thereby buffering the force applied to the escalator 3 and reducing the impact and damage to the escalator 3. At the same time, the first telescopic sleeve 7 and the second telescopic sleeve 22 can adjust the length by telescoping to adapt to the dynamic displacement of the cage body 1 caused by tides and wind and waves. When the escalator 3 needs to be replaced, the rotating rod is driven to rotate by starting the motor 15, so that the movable plate 16 moves in the direction away from the motor 15, and pushes the pushing plate 17 to deflect, so that the pushing plate 17 drives the limiting plate 18 away from the connecting rod 8 and the fixed rod 9, and no longer connects with the limiting port. When the limiting plate 18 close to the fixed rod 9 in the third mounting block 6 moves in the direction away from the fixed rod 9, it drives the movable rod 19 and the baffle 21 to move, so that the baffles at the upper and lower ends of the movable rod 19 21 moves from the movable opening to the movable groove, and at the same time, 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 opening on the fixed rod 9 in the middle of the second mounting block 5, so that the limiting component no longer limits the connecting rod 8 and the fixed rod 9 connected to the escalator 3. When the movable rod 19 moves, it drives the connecting plate 23 and the first tooth plate 24 to move, so that the gear 26 drives the movable shaft to rotate, so that the second tooth plate 25 drives the plug block 27 to separate from the second telescopic sleeve 22, and no longer fixes the second telescopic sleeve 22, and then separates the second telescopic sleeve 22 from the second mounting block 5 and the third mounting block 6, and removes 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 from the cage body 1, so that the escalator 3 can be disassembled from the cage body 1 for replacement.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
