On the installing plate at two ends；And the shearing cylinder pin socket inner sleeve being segmented is equipped with a shearing bearing pin, and shearing bearing pin is applied in segmentation
Shearing cylinder pin socket in, be set with a shearing orifice plate on shearing bearing pin, and shear orifice plate make umbilical cables terminal guide holder with
Mud mat positioned at bottom is connected with each other can cut off end, and the one end for making umbilical cables terminal guide holder is rotatable end, the other end
For end can be cut off.
The shear groove is located at the middle part of installing plate；Shearing orifice plate is located in shear groove.
The two ends of the fixed pin shaft are respectively installed with a fixed pin shaft orifice plate, and fixed pin shaft orifice plate is located at fixed cylinder pin
The two ends of sleeve, and the fixed pin shaft orifice plate supplies umbilical cables terminal guide holder mutually to interconnect in fixing end with the mud mat positioned at bottom
Connect.
The two ends of the shearing bearing pin are separately installed with a spacer pin, to the axial movement for limiting shearing bearing pin.
The fixed pin shaft orifice plate both sides are separately installed with a spacer pin, to the axial movement for limiting fixed pin shaft.
Beneficial effects of the present invention：Due to adopting above-mentioned technical proposal, which is led by umbilical cables the present invention in larger pulling force
When drawing umbilical cables terminal, installed in the shearing orifice plate of one end on mud mat, in the presence of shearing force, bearing pin is cut off；Now,
Umbilical cables terminal guide holder can be rotated around fixed pin shaft, after a set angle is turned over, the guide cone of umbilical cables terminal from
Depart from umbilical cables terminal guide holder, and then reach the purpose of protection umbilical cables；Avoid under water umbilical cables because fishnet is pulled or
Drawn by accidental external force and be damaged under water, efficiently solve the protection problem of umbilical cables under water.
