Description
Technical field
It the utility model is related to a kind of extra large cable protection device, more particularly to a kind of extra large cable bending limiting protector.
Background technology
With the increasingly scarcity of land resources, people depending on eye ocean has been invested, and marine resources are enriched, and marine resources are opened
Hair, such as oil gas, wind-powered electricity generation, tide energy etc. all be unable to do without power Transmission, and submarine cable is the main medium of power Transmission, its safety
Reliability concerns the normal operation of whole system, but ocean is a complicated natural environment, in submarine cable operation and for a long time
In running, the situation of transition bending may be met, once its bending radius of the degree of crook of extra large cable is curved more than minimum allowable
Bilge radius, the performance and used life of extra large cable will be affected, and extra large cable bending damage is directly contributed under serious conditions.
Therefore the position for needing that transition bending easily occurs in extra large cable is installed by a kind of device that can limit extra large cable bending, mesh
Preceding to have had a kind of extra large cable bending limiting protector, it is made up of at least two bending restrictor elements interlocks, each described
Bending restrictor element is made up of two semicircular bending limiting units；It is used for extra large cable provided with one in bending restrictor element
The extra large cable through hole passed through, a convex disk of connection is provided with the outside of the bending restrictor element of extra large cable through hole front end, in extra large cable through hole
The inwall of the bending restrictor element of rear side is provided with a connecting groove corresponding with connecting convex disk and in bending restrictor element
Rear end forms a convex clasp, and existing extra large cable bending limiting protector is by some bending restrictor elements when in use
It is set on by cable through-hole on the outside of extra large cable, two neighboring bending restrictor element is connected by connecting convex disk with connecting groove lock
Composition chain is connect, the extra large cable bending limiting protector of chain is designed with minimum bending radius, after extra large cable is placed in one, can hindered
Only extra large cable transition is bent；But existing extra large cable bending limiting protector, in flexural loading, connect the outer end of convex disk and
Stress concentration point occurs on convex clasp, so that bending restrictor element easily destroys, once bending restrictor is first
Part is destroyed, and bend protection effect will be lost to extra large cable.
The content of the invention
For disadvantage mentioned above, the purpose of this utility model is to provide a kind of stress concentration when can reduce stress and raising
The extra large cable bending limiting protector of safety coefficient during use.
Technology contents of the present utility model are that a kind of extra large cable bends limiting protector, and it is limited by least two bendings
Device elements interlock is formed, and each bending restrictor element is made up of two semicircular bending limiting units；Limited in bending
One is provided with device element processed and is used for the extra large cable through hole that extra large cable passes through, is set on the outside of the bending restrictor element of extra large cable through hole front end
There is the convex disk of a connection, a connection corresponding with connecting convex disk is provided with the inwall of the bending restrictor element on rear side of extra large cable through hole
Groove simultaneously forms a convex clasp in bending restrictor element rear end；It is characterized in that set in the two sides for the outer end for connecting convex disk
For inclined plane, the inclined angle alpha of two sides is 3~10 °；An outward-dipping inclined plane is provided with the inner surface of interior cam ring, it is interior
The angle of inclination of the two sides of outer end of the angle of inclination on surface with connecting convex disk is identical.
The utility model is compared with prior art advantageously：The utility model is by will connect the outer end of convex disk
The inner surface of two sides and convex clasp be set to inclined plane, connecting convex disk during extra large cable bending limiting protector bending
Point contact on outer end and convex clasp, is optimized for linear contact lay, so as to greatly reduce stress concentration, the use for improving product can
By property, so as to ensure the reliability of extra large cable.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of extra large cable bending limiting protector, it is by least two bending restrictors member
The interlocking composition of part 1, each bending restrictor element 1 are made up of two semicircular bending limiting units 1.1；Limited in bending
One is provided with device element 1 processed and is used for the extra large cable through hole 1.2 that extra large cable passes through, the bending restrictor element 1 in the front end of extra large cable through hole 1.2
Outside be provided with a convex disk 1.3 of connection, be provided with the inwall of the bending restrictor element 1 of the rear side of extra large cable through hole 1.2 one with even
Connect connecting groove 1.4 corresponding to convex disk 1.3 and form a convex clasp 1.5 in the rear end of bending restrictor element 1；It is characterized in that
Two sides 1.3.1,1.3.2 in the outer end for connecting convex disk 1.3 are set to inclined plane, and two sides 1.3.1,1.3.2 inclined angle alpha are
5°；An outward-dipping inclined plane, inner surface 1.5.1 angle of inclination and company are provided with the inner surface 1.5.1 of interior cam ring 1.5
The angle of inclination for meeting two sides 1.3.1,1.3.2 of the outer end of convex disk 1.3 is identical.
Operation principle of the present utility model is that extra large cable bending limiting protector is by some bending restrictors when in use
Element 1 is set on the outside of extra large cable 2 by cable through-hole 1.2, two neighboring bending restrictor element 1 by connect convex disk 1.3 with
The lock connection composition chain of connecting groove 1.4, when extra large cable puts stress bending, extra large cable bending limiting protector is driven to occur curved
Song, now because two sides 1.3.1,1.3.2 of outer end and the inner surface 1.5.1 of convex clasp 1.5 for connecting convex disk 1.3 are set to
Inclined plane, contact area is which increased, a contact, be optimized for linear contact lay, stress concentration can be reduced, improve making for product
With reliability, so as to ensure the reliability of extra large cable.
