Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figures 1 to 9, the utility model provides a kind of insulating tube, including inner tube 1 and heat-insulation layer 2, heat-insulation layer 2
Closely it is sheathed on outside inner tube 1, the optical fiber 3 for being capable of thermometric is contained in the inside of heat-insulation layer 2.
Insulating tube of the present utility model, by being provided for the optical fiber 3 of thermometric in heat-insulation layer 2, is surveyed using existing fiber
The advantage of temperature technique, according to the temperature change that optical fiber 3 is sensed, finds and determines breakthrough position in time.When inner tube 1 weld bond or
When seepage occur in other positions of inner tube 1, the thermal source (such as hot water or hot gas) in inner tube 1 oozes out into the seepage by leakage
The outer set heat-insulation layer 2 in place, because the temperature of heat-insulation layer 2 is relatively low than the temperature of the thermal source in inner tube 1, the thermal source for oozing out
Material can raise the temperature of the heat-insulation layer 2 of leakage outside setting, now, feel by being embedded in the optical fiber 3 in heat-insulation layer 2
The temperature change is measured, meanwhile, the optical signal containing temperature information and positional information feature can be sent to terminal and set by optical fiber 3
It is standby, and the optical signal is parsed into the leak source so that it is determined that pipeline by the terminal device, it is to dispose and avoid breakthrough in time
Position expansion provide information so that for accident treatment and as the case may be scheme of arrangement overhaul provide related data.In addition,
The easy aging, corrosion in insulating tube of the plain conductor of the measurement resistance value of prior art, overall plan is complicated, corollary equipment facility
It is many and maintenance cost is high, and optical fiber is corrosion-resistant and non-aging, service life can avoid existing seepage system up to more than 30 years
What system easily occurred misrepresents deliberately and reports phenomenon by mistake, extends the service life of insulating tube and detecting system.
In one embodiment as shown in fig. 1, the insulating tube in the embodiment is that optical fiber 3 is directly embedded in into heat-insulation layer
In 2, when embedded, optical fiber 3 is made as far as possible parallel to the axis of inner tube 1.When only monitoring of leakage is carried out to heating main pipe, insulation
An optical fiber 3 can be comprised only in layer 2, as shown in Figures 2 and 3.If in practicality, not only needing to carry out heating main pipe
Monitoring of leakage, in addition it is also necessary to which monitoring of leakage is carried out to lateral, then, the insulating tube employed in lateral, then using
Be provided with two optical fiber 3 in heat-insulation layer 2, preferably can using the both sides for making two optical fiber 3 be arranged on the axis of inner tube 1, such as Fig. 4 and
Shown in Fig. 5.In heating main pipe and lateral junction, the setting of insulating tube is as shown in fig. 6, heating main pipe uses two
One insulating tube of optical fiber 3 is only set, and lateral is provided with two insulating tubes of optical fiber 3 using one.
The production method of the insulating tube is produced by the way of prefabricated, i.e., set optical fiber 3 by the way of pre-buried
Put in heat-insulation layer 2.When using, the inner tube 1 in multiple insulating tubes successively head and the tail is connected, as shown in Figures 2 to 5, then
Pipeline is suppressed, if suppressing no problem, the optical fiber 3 (two i.e. adjacent optical fiber 3) of the two neighboring insulating tube is passed through
The correspondence of fibre-optical splice 5 is connected, and other operations can be carried out after the no problem of optical fiber 3 after test connection.
In insulating tube process of deployment, the fibre-optical splice more than 5 for using, the signal attenuation for causing is more.In order to avoid
This problem, as shown in Figure 7 in a specific embodiment, at least one penetration pipe 9 is provided with heat-insulation layer 2, and optical fiber 3 sets
It is placed in penetration pipe 9, in order to construct.In order that the optical fiber 3 in penetration pipe 9 during setting, can make parallel to the axis of inner tube 1
The diameter parallel of penetration pipe 9 is in the axis of inner tube 1.It is same as above, a penetration pipe 9 can be set in heat-insulation layer 2, it is also possible to set
Two penetration pipes 9 are put, as shown in Figure 9.When heat-insulation layer 2 is contained within two penetration pipes 9, as shown in Figure 7 and Figure 8, two threading
Pipe 9 is arranged on the both sides of the axis of inner tube 1.
In the present embodiment, along the axis direction of inner tube 1, the length of the length less than inner tube 1 of heat-insulation layer 2, i.e., such as Fig. 1 institutes
Show, heat-insulation layer 2 is exposed at the two ends of inner tube 1.
The insulating tube also includes the outer tube 4 outside heat-insulation layer 2, and the diameter parallel of outer tube 4 is in the axis of inner tube 1.
Therefore the utility model also proposed a kind of pipeline intelligent monitoring of leakage early warning system, the pipeline intelligent seepage prison
Detection early warning system contains the insulating tube that many head and the tail are sequentially connected, and the insulating tube is above-mentioned insulating tube, two adjacent optical fiber 3
Connected by the correspondence of fibre-optical splice 5, the pipeline intelligent monitoring of leakage early warning system is also containing being used for launching laser in optical fiber 3
The laser signal transmitter 6 of signal and the laser signal receivers 7 for receiving the laser signal in optical fiber 3, optical signal launch
Device 6 and laser signal receivers 7 are connected with the signal of optical fiber 3, and laser signal receivers 7 are also associated with control unit 8.Such light
Optical signal containing pipe temperature information and positional information feature can be sent to terminal device (i.e. control unit 8) by fine 3, by this
The optical signal is parsed the leak source so that it is determined that pipeline by control unit 8.Using the use set in the heat-insulation layer 2 of the insulating tube
In the optical fiber 3 of thermometric, optical fiber 3 can be sent to the data of control unit 8 and initial data is contrasted, so that it is determined that pipeline is
No seepage and respective point position.
From the foregoing, insulating tube of the present utility model and current external plain conductor default in the duct, to measure
Resistance value come judge pipeline whether seepage principle it is entirely different, corrosion-resistant, anti-magnetic interference that optical fiber is had by itself,
The features such as low cost, is having the advantages that more only on material character according to external wire, and its overall technical architecture is not only
Construction and installation link is simple, construction quality is easy to control, seepage judges and point level is true, and its total cost is also very low, there is wide
Wealthy application prospect.
The above, only specific embodiment of the utility model, it is impossible to which the scope that utility model is implemented, institute are limited with it
With the displacement of its equivalent assemblies, or the equivalent variations made according to the utility model scope of patent protection and modification, should all still fall within
The category that this patent is covered.In addition, between technical characteristic and technical characteristic in the utility model, technical characteristic and technical scheme
Between, can be used with independent assortment between technical scheme and technical scheme.
