[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-Figure 3 , a special blowout preventer for sealing an underwater umbilical cable, comprising a blowout preventer body 1, two driving devices 2 are fixedly installed on the left and right sides of the blowout preventer body 1, a driving shaft 9 is installed on the end of the driving device 2 away from the blowout preventer body 1, a connecting ring 3 is rotatably connected to the end of the driving device 2 away from the blowout preventer body 1, and a protective component for preventing the driving shaft 9 from being touched is provided at the end of the connecting ring 3 away from the blowout preventer body 1, and the protective component comprises a protective shell 5 fixedly installed on the side wall of the connecting ring 3, the corner of the end of the protective shell 5 away from the connecting ring 3 is a rounded structure, and the end of the protective shell 5 away from the connecting ring 3 is provided with a protective sleeve 6 for protecting personnel, the protective sleeve 6 is made of rubber material, and prevents people from being injured when colliding with the protective shell 5, and plays a protective role, a through hole 4 is provided on the side of the protective shell 5, the middle part of the through hole 4 is a cylindrical structure, and the upper and lower parts are both rectangular structures, and the driving shaft 9 is located inside the through hole 4;

[0024] A toggle assembly for rotating the drive shaft 9 is provided at one end of the drive shaft 9 away from the blowout preventer body 1. The toggle assembly includes a groove 8 provided on the end surface of the drive shaft 9. A rotatable toggle plate 7 is provided inside the groove 8. The toggle plate 7 is rotated by the damping shaft. The damping shaft can stop the toggle plate 7 at will without swinging easily. The width of the toggle plate 7 is smaller than the diameter of the drive shaft 9. When the toggle plate 7 is retracted into the protective shell 5, it is in a horizontal state, and the rotation of the protective shell 5 will not affect the toggle plate 7.

[0025] Working principle:

[0026] When in use, it is only necessary to rotate the protective shell 5 so that the through hole 4 is aligned with the toggle plate 7. At this time, the toggle plate 7 can be pushed, and the toggle plate 7 rotates around the damping shaft and is in a vertical state, and the driving shaft 9 can be controlled to rotate;

[0027] When the vehicle is parked, the toggle plate 7 only needs to be retracted into the protective shell 5 to be in a horizontal state. At this time, even if the protective shell 5 is touched and rotated, the toggle plate 7 and the driving shaft 9 will not be affected.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
