Wherein, by being coated with one layer of heat discoloration in electric-heating belt ontology in electric-heating belt provided in this embodiment
Layer, heat discoloration layer change colour according to the temperature change of electric-heating belt ontology, i.e. the temperature change transformation of electric-heating belt ontology
It is shown for color, such testing staff just can judge whether electric-heating belt is normal according to the color change of heat discoloration layer
Work, to achieve the purpose that electric-heating belt fault detection, therefore, electric-heating belt provided in this embodiment carries fault detection
Function, patrol officer can be assisted convenient for the electric-heating belt of discovery damage in time, the routing inspection efficiency greatly improved and inspection matter
Amount improves safety in production level.
In the present embodiment, as shown in Figure 1, electric-heating belt includes: electric-heating belt ontology 20 and is coated on electric-heating belt sheet
Body 20 is outer and can be used for the heat discoloration layer 10 that temperature change changes colour, heat discoloration layer 10 according to electric-heating belt ontology
20 temperature change changes colour, and such patrol officer just can detect electric-heating belt according to the color that heat discoloration layer 10 is shown
Whether work normally, specifically, the temperature of electric-heating belt ontology 20 has reached temperature-sensitive change when electric-heating belt ontology 20 works normally
The discoloring temperature of chromatograph 10, at this point, heat discoloration layer 10 can change colour according to the temperature of electric-heating belt ontology 20, heat discoloration
Layer 10 shows a kind of color, and when breaking down on electric-heating belt ontology 20, the temperature of fault zone is lower than heat discoloration layer 10
Discoloring temperature, heat discoloration layer 10 will not change colour at this time, and heat discoloration layer 10 is restored to by the color after changing colour and is not sent out
Change color when color, wherein color when heat discoloration layer 10 does not change colour can be the face of heat discoloration layer 10 itself
Color, the different colours that such patrol officer shows according to heat discoloration layer 10 just can judge the working condition of electric-heating belt, example
Such as when the color of heat discoloration layer 10 itself is black, when discoloration, the color that heat discoloration layer 10 is shown is green, such inspection
Personnel then judge that the temperature of electric-heating belt is normal, if inspection if it is observed that when the entire outer surface of electric-heating belt is green
Personnel in green area if it is observed that have black region, then black on the electric-heating belt of surface on the outer surface of electric-heating belt
The temperature of the corresponding position in region is abnormal, and the electric-heating belt at this breaks down, and can not work normally, the present embodiment
In, since electric-heating belt can change colour, such patrol officer especially at night inspection when, can be easily to electric tracing
The state of band is detected, and is very easy to find the fault zone on electric-heating belt, greatly reduces the work of patrol officer
Amount, inspection process are time saving and labor saving.
Wherein, in the present embodiment, heat discoloration layer 10 is arranged in the entire outer surface of electric-heating belt, such heat discoloration layer
10 can change colour according to the temperature change of any one position on electric-heating belt, i.e., each position is ok on electric-heating belt
It is detected by warm photochromic layer, and in the prior art, when electric-heating belt length is longer, by checking electric tracing in distribution box

When, increase the weight of electric-heating belt, therefore, in the present embodiment, 10 thickness of heat discoloration layer is set with specific reference to actual demand
It is fixed.
Further, on the basis of the above embodiments, in the present embodiment, since heat discoloration layer 10 is electric-heating belt
Outmost one layer, and heat discoloration layer 10 is made of thermosensitive chromotropic material, so in order to be protected to thermosensitive chromotropic material,
In the present embodiment, the protective layer of layer of transparent can be set outside heat discoloration layer 10, it so both will not be to heat discoloration layer 10
Color impact, while can also play a protective role to heat discoloration layer 10, wherein in the present embodiment, protective layer tool
Body can be formed using transparent adhesive tape, specifically, transparent adhesive tape can be covered on heat discoloration layer 10.
Embodiment two
Fig. 3 is the schematic diagram of the section structure for the electric-heating belt that the utility model embodiment two provides.
In the present embodiment, since heat discoloration layer 10 is become by perceiving the temperature change of electric-heating belt ontology 20
Color, thus between heat discoloration layer 10 and electric-heating belt ontology 20 if there is gap when, then can make heat discoloration layer 10
There is deviation in discoloration and the temperature change of electric-heating belt ontology 20, cause in this way according to the color change of heat discoloration layer 10 come pair
Occur the situation of judgement inaccuracy when the work of electric-heating belt ontology 20 judges, for this purpose, in the present embodiment, electric-heating belt ontology 20
It is set to heat-conducting layer 21 between heat discoloration layer 10, heat discoloration layer 10 can be made accurately to perceive by heat-conducting layer 21 in this way
To the actual temperature of electric-heating belt ontology 20, so that being the practical temperature of electric-heating belt ontology 20 when heat discoloration layer 10 changes colour
Degree, so that the color change of heat discoloration layer 10 can accurately reflect the working condition of electric-heating belt.
The electric-heating belt of the present embodiment offer, by including electric-heating belt ontology 20 and being coated on electric-heating belt ontology
It and can be with the heat discoloration layer 10 that temperature change changes colour outside 20, so that the electric-heating belt outer surface of the application has
The heat discoloration layer 10 of one layer of changeable colour, when the temperature of the electric-heating belt ontology 20 in electric-heating belt changes, temperature-sensitive becomes
Chromatograph 10 changes the color of electric-heating belt outer surface according to the temperature change of electric-heating belt ontology 20, and such patrol officer is to electric companion
When the torrid zone is checked, the color change that need to only observe electric-heating belt outer surface just can judge whether electric-heating belt works just
Often, so that inspection process was not only simple but also efficient, to substantially increase routing inspection efficiency and inspection quality, safety in production water is improved
It is flat, and heat discoloration layer 10 is coated on the entire outer surface of electric-heating belt ontology 20, has been achieved whole to electric-heating belt
The purpose that each position of a outer surface is detected, avoids and detects electricity by checking distribution box temperature in the prior art
Occur that the detection of electric-heating belt bulk temperature is normal when heating tape and middle section is likely to occur not hot drawback, therefore, this implementation
The electric-heating belt that example provides realizes and changes that electric-heating belt is normal or the mesh of failure to detect according to electric-heating belt self color
, routing inspection efficiency and inspection quality are substantially increased, solves detection when existing electric tracing detection device detects electric tracing
Not comprehensive and inaccurate technical problem.
Meanwhile by being set to heat-conducting layer 21 between electric-heating belt ontology 20 and heat discoloration layer 10, so that temperature-sensitive
Photochromic layer 10 accurately perceives the actual temperature of electric-heating belt ontology 20, so that being electric companion when heat discoloration layer 10 changes colour
The actual temperature of tropical ontology 20, it is ensured that the accurate detection of 10 pairs of electric-heating belt of heat discoloration layer.
