Description
Technical field
The present invention relates to temperature monitoring technique fields, and in particular, to a kind of overtemperature warning nut.
Background technique
In actual operation, due to splicing fitting junction bolt looseness, contact surface is dirty, cable tail pipe envelope for power circuit
Lead loosely, copper Al electrochemical corrosion etc. reasons be easy to cause resistance to become larger, when big load, high current, easily cause
Local temperature is excessively high and causes various failures.And failure caused by splicing fitting often can not be self-healing, needs to put into big
The manpower and material resources of amount are repaired, and are affected greatly to power grid to society.
Therefore, it is necessary to carry out regularly maintenance to power circuit splicing fitting to monitor, existing main method is pair for pole
Splicing fitting carries out regularly infrared measurement of temperature, to search heating accident.Operations staff periodically surveys route by O&M strategy
Temperature detector is surveyed, and is especially hit new peak in line load, night carries out thermometric, heavy workload.In addition, infrared measurement of temperature there are it is following not
Foot：It is protected from environmental larger, cannot be carried out in the bad environments such as dust, smog, steam region；It is to smooth metal surface
Measurement accuracy is not high；The thermometric period is long, it cannot be guaranteed that finding defect in time；Part fever is the variation with load and changes, red
Outer thermometric is difficult to capture heating defect, can only measure state at that time, cannot record overtemperature state；On-Line Monitor Device power supply is not
Stabilization, the easy failure of data sensor module, communication module reliability is low causes single unit system reliability extremely low, device overall cost mistake
It is high.
In addition, also there is exploitation on-line monitoring temperature measuring equipment on the market, device supervises power circuit splicing fitting temperature
Control, but reliability is not high.Therefore, now it is badly in need of researching and developing a mechanical overheating warning device, generates heat route splicing fitting and carry out
Early warning is visualized, the deficiency of infrared measurement of temperature and on-Line Monitor Device is made up.
Summary of the invention
It is existing vulnerable to environment when being monitored to splicing fitting that the purpose of the present invention is to solve the prior arts
It influences, the technological deficiency not high to splicing fitting measurement accuracy, provides a kind of overtemperature warning nut.The overtemperature warns nut
Fastening bolt and overtemperature warning function can be played simultaneously, on equipment without influence, eliminate security risk, strong applicability.
To achieve the goals above, the present invention is achieved by following scheme：
A kind of overtemperature warning nut, including nut, the temperature sensing glass ball for being fixed on nut top, bottom end and temperature sensing glass ball top
Terminal, spring cup, pull rod, compression spring and the warning tape being fixedly connected；The terminal cylinder closed in top end opening, bottom end
Shape offers through-hole on bottom end；The spring cup covers the opening on terminal top, and by pull rod pass through through-hole with

It connects/contacts；The both ends of the warning tape are connect with the inner wall of spring cup, terminal respectively.
Nut has obtained extensive reference in splicing fitting, therefore on the linkage function on nut basis, fastening function
Increase overtemperature alarm function, effectively the temperature of splicing fitting can be monitored, and in overtemperature, reminds work people in time
Member.Use and common nut of the nut provided by the invention in terms of connection, fastening have no difference, now surpass to it emphatically
The principle of temperature warning is introduced：
Nut is fixed on object under test, the temperature of object under test can be perceived by the temperature sensing glass ball on nut, to be measured
When the temperature of object is higher than the early warning temperature of temperature sensing glass ball, temperature sensing glass ball crack damage, since compression spring is under normality
In compression contraction state, temperature sensing glass ball crack damage back stay can not be provided to spring cup maintains compression spring compression to receive
The power of contracting state, spring cup removes at this time, no longer covers to the opening of terminal, and warning tape is pulled out out of terminal.?
When practical application, technical staff need to only observe whether warning tape is pulled out from terminal, that is, whether can determine object under test
Beyond early warning temperature.
Preferably, the nut and terminal integrated setting, offer accommodating cavity between nut top and terminal bottom end,
The temperature sensing glass ball is arranged in accommodating cavity, and temperature sensing glass ball passes through through-hole by pull rod and connect with spring cup.
Preferably, the side of the accommodating cavity offers the perforation for installing temperature sensing glass ball, is conveniently replaceable temperature-sensitive
Nut may be reused in glass marble.
Preferably, the nut interior is equipped with screw thread, and the nut can choose different dimensions and screw thread
Depth, to cooperate corresponding bolt size and length.
Preferably, the both ends of the warning tape pass through fastening screw respectively and are fixed on the inner wall of spring cup and terminal.
Preferably, the warning tape is colored ribbon, and the color of colored ribbon is customized according to temperature alarm, and different colours generation can be set
The different temperature alarm of table.
Preferably, the temperature sensing glass ball is customized according to temperature alarm.
Preferably, overtemperature warning nut surface covers one layer of temperature sensitive fluorescence coating, when the temperature of object under test exceeds
When early warning temperature, temperature sensitive fluorescence coating shines, and nut can be warned to be applied in night field high altitude overtemperature, facilitate staff
It observes in dark conditions.
Preferably, the diameter of the compression spring and the internal diameter of terminal are equal.
Preferably, the terminal upper portion is equipped with the card slot for retaining spring lid.
Preferably, the diameter of the spring cup and the internal diameter of card slot are equal.
Compared with prior art, the invention has the advantages that：
（1）Overtemperature warning nut provided by the invention is perceived by the temperature of temperature sensing glass ball measuring targets, to be measured
When the temperature of object is higher than early warning temperature, temperature sensing glass ball crack damage makes to warn by the control of corresponding mechanical structure at this time
Band pulls out, and can prompt the temperature of staff's object under test beyond early warning temperature, has that high reliablity, structure be simple, cost
Advantage low, easy to install.
（2）Overtemperature warning nut provided by the invention can play fastening bolt and overtemperature warning function simultaneously, to equipment
Without influence, security risk, strong applicability are eliminated.Overtemperature warning nut floats when can be more than predetermined temperature to connection fitting
Warning band carries out early warning out, records overtemperature state, is shown by visual mode, and technical staff's naked eyes can find to generate heat
Defect compensates for the thermometric period length of infrared measurement of temperature and is difficult to capture the deficiency of heating defect.
（3）Overtemperature warning nut provided by the invention is a kind of mechanical temperature sensing device, not by the shadow of weather, environment etc.
Ring, also do not limited by the surface smooth degree of measured body, can avoid well infrared measurement of temperature influenced by weather, environment and
The smooth influence in measured object surface.
