The surface in road.
The utility model solves above-mentioned existing technical problem and easily attaches optical cable, including sheath there is provided a kind of；The sheath
Section be in flat, the length value in the sheath section is 3 to 5 times of width value.
The utility model is further improved as described below.
The two ends profile of the flat is respectively a semi arch, just to two halves circular arc between connected respectively by two parallel lines
Connect.
The radius of two halves circular arc is identical.
Including coated fiber, fine ointment, Loose tube, tight tube fiber and sheath；The Loose tube is sheathed on the coating light
Fibre, and the filling fine ointment in it；The coated fiber helically case of bending；The Loose tube, the tight tube fiber are equal
It is fixed on the inside of the sheath；The tight sleeve pipe of the tight tube fiber is identical with the material of the sheath.
The concentrically line of semi arch described in the tight tube fiber and one；The tight tube fiber and another semi arch are concentrically
Line.
In the central region of the sheath, flat cavity is set.
The flat cavity is in fusiform.
The length of the flat cavity is the half of the sheath cross-sectional length.
Including aramid yarn, the aramid yarn is arranged in the flat cavity.
Compared to prior art, the beneficial effects of the utility model are：Sheath is arranged to flat, and the length in sheath section
Angle value is 3 to 5 times of width value so that this, which easily attaches optical cable, can match the surface for being attached at circular pipe.Meanwhile, coat light
Fine helically case of bending, more accurately resolved temperature can be changed by the optical signal of the optical cable.The tight sleeve pipe of tight tube fiber with
The material of the sheath is identical, and when extruding sheath, sheath can be with tight sleeve pipe adhesion so that the structure of optical cable is compacted, unification degree

Embodiment
Explanation and embodiment are further illustrated to the utility model below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of easily attach optical cable, including sheath 15；The section of the sheath 15 is in flat, the section of sheath 15
Length value is 3 to 5 times of width value.Sheath 15 is arranged to flat, and the length value in the section of sheath 15 is the 3 to 5 of width value
Times so that this, which easily attaches optical cable, can match the surface for being attached at circular pipe.
Specifically, the two ends profile of the flat is respectively a semi arch, just to two halves circular arc between by two straight parallels
Line is connected respectively, and the radius of two halves circular arc is identical.
Easy attaching optical cable of the present utility model also includes coated fiber 11, fine ointment 12, Loose tube 13, the and of tight tube fiber 14
Sheath 15；Loose tube 13 is sheathed on coated fiber 11, and the fine ointment 12 of filling in it；The helically case of bending of coated fiber 11；
Loose tube 13, tight tube fiber 14 are both secured to the inside of sheath 15；The tight sleeve pipe 141 of tight tube fiber 14 and the material phase of sheath 15
Together.By the semi arch of tight tube fiber 14 and one, concentrically line is set；By tight tube fiber 14 and another semi arch, concentrically line is set.This
Sample coated fiber 11 is used for temperature-compensating.When optical cable by stress produce deformation, coated fiber 11 due to length of having a surplus, can not by should
Become influence, it is only sensitive to temperature change.Then optical signal is gathered, is analyzed, i.e., accurately resolved temperature can be changed.Meanwhile,
The tight sleeve pipe 141 of tight tube fiber 14 is identical with the material of sheath 15, and when extruding sheath 15, sheath 15 can be sent out with tight sleeve pipe 141
Raw adhesion so that the structure of optical cable is compacted, unification degree high.When optical cable is by stress generation deformation, tight tube fiber 14 is long due to nothing left,
Can not temperature influence, only to strain sensitive.Then optical signal is gathered, is analyzed, i.e., can accurately differentiate strain
Change.Therefore, this easily attach optical cable i.e. can resolved temperature change, can also differentiate strain variation.
Sheath 15 can also use identical hardness using the low material of low-smoke halogen-free flame-retardant sheath 15 of hardness, tight sleeve pipe 141
The low material of low-smoke halogen-free flame-retardant sheath 15, so as to provide advantage to being attached at tube circular surface, it is adaptable to colliery, oil well, stone
The strain abnormality monitoring system of oil-piping or natural gas line.
The utility model sets flat cavity 151 in the central region of sheath 15, and flat cavity 151 is in fusiform, flat
The length of cavity 151 is the half of the cross-sectional length of sheath 15, so that the attaching ability on tube circular surface is further improved on, should
Flat cavity 151 can be formed by the mould straight forming of sheath 15.The utility model strain transducer includes aramid yarn 16, aramid fiber
Yarn 16 is arranged in flat cavity 151, can ensure that the tensile property of optical cable is excellent.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to protection domain of the present utility model.
