[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0020] As Figures 1-4 shown, the present utility model provides a technical solution: a heave compensator for deep-sea operations, including a suspension beam 1, with a mounting hole 2 opened above the suspension beam 1, fixing holes 3 opened on both sides of the suspension beam 1, a slide groove 4 provided below the suspension beam 1, a fixed frame 5 slidably installed in the slide groove 4, a slide block 8 connected above the fixed frame 5. The slide block 8 is of T-shaped design and is slidably connected to the slide groove 4. Through the sliding of the T-shaped slide block 8 in the slide groove 4, the fixed frame 5 can move smoothly along the suspension beam 1, and the staff only needs to push the slide block 8 to install the fixed frame 5 on the suspension beam 1, improving the installation efficiency.

[0021] A connection groove 6 is opened on the fixed frame 5, and a protective cover 7 is slidably connected to the fixed frame 5 through the connection groove 6. A pull rod 701 is connected below the protective cover 7, a connection strip 702 is connected to the inner wall of the protective cover 7, and a first threaded hole 703 is opened on the protective cover 7. The inside of the fixed frame 5 is protected by the protective cover 7 to prevent the internal parts from being corroded by bad weather, thus ensuring the normal service life.

[0022] Fixed plates 9 are connected to both sides above the fixed frame 5, and a second threaded hole 20 is opened on the fixed frame 5. The first threaded hole 703 and the second threaded hole 20 have the same size and correspond to each other. The connection strip 702 is slidably connected to the connection groove 6. Through the sliding connection of the connection strip 702 and the connection groove 6, the staff can quickly position and install the protective cover 7. When the connection strip 702 completely enters the connection groove 6, the first threaded hole 703 and the second threaded hole 20 will be aligned with each other, facilitating the fixation by the worker and improving the assembly efficiency.

[0023] A fixed seat 10 is connected inside the fixed frame 5. A fixed pulley 11 is rotatably connected to the fixed seat 10. An accumulator 12 is installed on the fixed seat 10. A hydraulic cylinder 13 is installed on the fixed seat 10. The movable end of the hydraulic cylinder 13 is connected to a movable seat 14. A movable pulley 15 is rotatably connected to the movable seat 14. There are two accumulators 12 and two hydraulic cylinders 13, and they are evenly distributed on both sides of the fixed pulley 11. The accumulator 12 and the hydraulic cylinder 13 are connected through a valve pipeline system. The movable seat 14 slides inside the fixed frame 5. Through the valves and pipeline system installed between the hydraulic cylinder 13 and the accumulator 12, the hydraulic cylinder 13 can compress or expand the energy storage gas in the accumulator 12 to push the movable seat 14, changing the distance between the movable pulley 15 and the fixed pulley 11, so as to release or retract the cable to adapt to the change of the cable tension.

[0024] A threaded rod 16 is threadedly connected to the fixing plate 9. One end of the threaded rod 16 is connected to a handwheel 17. The other end of the threaded rod 16 is rotatably connected to a clamping plate 18. A plurality of fixing rods 19 are connected to the side of the clamping plate 18 away from the threaded rod 16. The fixing rods 19 are inserted into the fixing holes 3. A sliding rod 21 is slidably connected to the fixing plate 9. One end of the sliding rod 21 is connected to the clamping plate 18. When the threaded rod 16 pushes the clamping plate 18 to move, the sliding rod 21 will slide on the fixing plate 9, thereby guiding the movement of the clamping plate 18 and enabling the clamping plate 18 to move smoothly.

[0025] The working principle of the present utility model is as follows:

[0026] During installation, first push the connecting strip 702 into the connecting groove 6 to align the first threaded hole 703 with the second threaded hole 20, so as to facilitate the staff to screw in the screws and fix the protective cover 7 on the fixed frame 5, thereby hermetically protecting the heave compensator through the protective cover 7 and reducing the influence of bad weather and falling objects on the heave compensator. Then push the slider 8 into the sliding groove 4 and rotate the threaded rod 16 by turning the handwheel 17, so that the threaded rod 16 pushes the clamping plate 18 to move, prompting the fixing rod 19 to insert into the fixing hole 3, thereby fixing the fixed frame 5 on the suspension beam 1. The operation is simple, improving the installation and disassembly efficiency, and the position of the fixed frame 5 on the suspension beam 1 can be conveniently adjusted by the sliding of the slider 8 in the sliding groove 4.
