Benefits of technology

[0015] This utility model uses a limiting mechanism to press down on the moving ring. External force pushes the snap-fit ​​component to move through the moving and fixed components, while simultaneously squeezing the fixed spring. During the compression process, the fixed spring stores elastic potential energy. When the snap-fit ​​component moves downward, it disengages from the guide port of the moving component and slides into the edge of the fixed component. When the fixed spring loses its limiting force and rebounds, the spring rebound force pushes the snap-fit ​​component to move. When it snaps into the fixed component, it pushes the moving component to move but does not completely reset, thus connecting the snap-fit ​​component with the protective component.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a self-unhooking traction device for a submarine cable perforation protection device, comprising a connector 1 and a protective component 2;

[0025] It also includes: a limiting mechanism 3, which is located on one side of the connector 1 and pulls the protective component 2;

[0026] Fixing mechanism 4 is located on the other side of connector 1 and is used to pull the submarine cable.

[0027] The limiting mechanism 3 includes a connecting ring 31 fixedly connected to one side of the connecting member 1. A fixing spring 32 is fixedly connected inside the connecting ring 31. A snap-fit ​​member 33 is fixedly connected to one end of the fixing spring 32. A fixing member 34 is snapped to one end of the snap-fit ​​member 33. A moving member 35 is slidably connected inside the fixing member 34. A moving ring 36 is fixedly connected to one end of the moving member 35.

[0028] When the protective component 2 is inserted into the connecting ring 31 and the moving ring 36 is pressed, the external force acts on the snap-fit ​​component 33 connected to the fixed spring 32 through the moving component 35 and the fixed component 34, causing the fixed spring 32 to be compressed. During the compression process, the fixed spring 32 stores elastic potential energy. When the snap-fit ​​component 33 moves, it comes out from the guide port of the moving component 35 and slides into the edge of the fixed component 34. When the fixed spring 32 rebounds, the spring rebound force pushes the snap-fit ​​component 33 and the moving component 35 upward, so that the snap-fit ​​component 33 and the fixed component 34 are snapped together. At the same time, the moving component 35 is pushed to produce a distance displacement and does not completely reset, ensuring that the snap-fit ​​component 33 is connected to the protective component 2 through the connecting component 1.

[0029] The connector 1 has a first slot inside that matches the snap-fit ​​33. The fixing member 34 is fixedly connected inside the connector 1. The protective member 2 is sleeved inside the connector 1. The surface of the protective member 2 has a connection hole that matches the snap-fit ​​33.

[0030] The first slot facilitates the movement and scaling of the snap-fit ​​part 33 and the fixing spring 32 inside the connector 1. The connector 1 fixes the position of the fixing part 34, ensuring that the moving part 35 moves inside the fixing part 34. The connector 1 restricts the position of the protective part 2. The connecting hole facilitates the snap-fit ​​part 33 to move into the protective part 2, so that the snap-fit ​​part 33 and the protective part 2 are connected.

[0031] The fixing mechanism 4 includes a limiting ring 41 fixedly connected to the other side of the connector 1. A first limiting block 42 is snapped onto the surface of the limiting ring 41. A spring rod 43 is fixedly connected to one end of the first limiting block 42. A rotating ring 44 is fixedly connected to one end of the spring rod 43. A fixing rod 45 is sleeved inside the rotating ring 44. An abutment 46 is fixedly connected to the bottom of the fixing rod 45. A moving groove 47 is opened on the surface of the rotating ring 44. A closing cover 48 is fixedly connected to the surface of the first limiting block 42. A second limiting block 49 is fixedly connected to the inside of the closing cover 48. A second empty groove that matches the second limiting block 49 is opened on the surface of the rotating ring 44.

[0032] Pulling the closing cover 48 causes the first limiting block 42 to disengage from the surface of the limiting ring 41 and compress the telescopic rod. At the same time, the second limiting block 49 moves on the surface of the rotating ring 44. Rotating the closing cover 48 causes the rotating ring 44 to rotate through the first limiting block 42 and the second limiting block 49. The rotation of the rotating ring 44 pushes the fixed rod 45, which is sleeved in the sliding groove, to move. The movement of the fixed rod 45 causes the contact member 46 to connect with the submarine cable.

[0033] One end of the rotating ring 44 is fixedly connected to a support rod 5, and the support rod 5 is rotatably connected inside the limiting ring 41;

[0034] The support rod 5 can connect the rotating rod to the limiting ring 41. The limiting ring 41 restricts the position of the support rod 5. The rotation of the rotating ring 44 causes the support rod 5 to rotate inside the limiting ring 41.

[0035] Example 2

[0036] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that one end of the connector 1 is fixedly connected to the traction head 6, one end of the traction head 6 is engaged with the first pin 7, and the other end of the traction head 6 is engaged with the second pin 8. The traction head 6 guides the movement of the device. The first pin 7 is connected to the traction wire rope, and the second pin 8 is connected to the traction net sleeve of the submarine cable. Under the traction of the traction wire rope, the device drives the submarine cable and the submarine cable perforation protection device together into the opening on the pile body of the monopile foundation.
