Description
Technical field
The utility model is related to municipal drainage facility detection technique fields, and in particular to a kind of temperature sensing optical cable structure.
Background technology
There is the hidden danger of rupture in the drainage pipeline in municipal drainage facility, if fault point cannot be found in time, in pipeline
Sewage leak and can cause great problem of environmental pollution, therefore, drainage pipeline is monitored in real time, finds to let out in time
Leakage and forecast hidden danger are highly important measures, but since drainage pipeline is buried in underground, to it is accurate, reliable, timely manage
Road surveying tape comes greatly difficult.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of temperature sensing optical cable structures, and tensile strength is big, bending resistance, pressure resistance
Performance is good, and reliability is high, long working life.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of temperature sensing optical cable structure, including center strengthening core, the first uniformly distributed light of strengthening core exterior circumferential at center
Fibre, the second optical fiber, first fixed fine and the second fixed fibre, and the first optical fiber, the second optical fiber, the first fixed fibre and second are fixed
It is fine it is adjacent two-by-two between be equipped with gasket for packing；First optical fiber, the second optical fiber, the first fixed fibre and the second fixed fine outside are successively
It is coated with organdy and MDPE sheaths.
Water resisting optical fiber ointment layer and PBT beam tubes are equipped with outside first optical fiber and the second optical fiber successively.
Tear rope is equipped in the MDPE sheaths and at organdy.
First optical fiber and the second optical fiber include the temperature sensing optical fiber of two specifications of the same race.
It is using advantageous effect caused by above-mentioned technical proposal：
The utility model tensile strength is big, bending resistance, good pressure-resistant performance, and reliability is high, long working life.By special designing
Cable configuration, can quickly transmit the optical fiber of external heat and cable interior, be especially suitable for industrial fire prison
Survey application and engineering construction demand.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, center strengthening core, the 2, first optical fiber, the 3, second optical fiber, the 4, first fixed fibre, the 5, second fixed fibre, 6,

Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, the utility model discloses a kind of temperature sensing optical cable structure, including center strengthening core 1, reinforce at center
The first uniformly distributed optical fiber 2 of 1 exterior circumferential of core, the second optical fiber 3, first fixed fine 4 and second fixed fine 5,2 He of the first optical fiber
Second optical fiber 3 includes the temperature sensing optical fiber of two specifications of the same race, and the first optical fiber 2, the second optical fiber 3, first fixed fine 4 and
Two fixed fine 5 it is adjacent two-by-two between be equipped with gasket for packing 6；It is equipped with water resisting optical fiber ointment layer successively outside first optical fiber 2 and the second optical fiber 3
10 and PBT beam tubes 11；It is coated with successively outside first optical fiber 2, the second optical fiber 3, first fixed fine 4 and second fixed fine 5
Organdy 7 and MDPE sheaths 8；Tear rope 9 is equipped in MDPE sheaths 8 and at organdy 7.
The temperature sensing optical cable of the utility model, in the sandstone layer of drainage pipeline bottom, is managed along duct orientation parallel lay-up with reaching
Think that monitoring effect, pipeline once leak, supply water leakage downwards, and the environment temperature at this changes, by monitoring in real time
The temperature change of ambient enviroment, so that it may to find the leak case of pipeline in time.
