Substantial amounts of manpower and materials are rushed to repair, and power network is affected greatly to society.
Therefore pole is necessary that power circuit splicing fitting is carried out regularly to safeguard monitoring, and existing main method is docking
Continuous gold utensil carries out regularly infrared measurement of temperature, to search heating accident.Operations staff periodically carries out thermometric by O＆M strategy to circuit
Detection, particularly hit new peak in line load and carry out thermometric with night.But infrared measurement of temperature is protected from environmental larger, it is impossible to
The bad environments such as dust, smog, steam region is carried out, and its measurement accuracy to smooth metal surface is not high.
The content of the invention
The present invention for solve prior art provide splicing fitting monitoring method existing for easily it is affected by environment, to the gold that continues
Has the not high technological deficiency of measurement accuracy, there is provided a kind of overtemperature alarming device of power circuit splicing fitting.
To realize above goal of the invention, the technical scheme of use is：
A kind of overtemperature alarming device of power circuit splicing fitting, including lateral opening and the housing of bottom surface opening, activity
Cover plate, motion bar, spring, fixed plate, portable plate, prompt band and temperature sensor；The fixed plate is fixed in housing, fixed plate with
Housing is fixedly connected, and through hole is offered in the fixed plate, and the portable plate and removable cover are separately positioned on the upper of fixed plate
Side and lower section, portable plate are arranged in housing, and removable cover covers to the bottom opening of housing, and removable cover passes through activity
Bar through being connected with portable plate after the through hole in fixed plate, the both ends of spring, the both ends of temperature sensor respectively with portable plate, fixed plate
Connection, prompt band are arranged on the motion bar between the top surface or fixed plate and removable cover of removable cover.
Under normal conditions, its internal spring is due to supporting role of the temperature sensor to portable plate and in drawing for overtemperature alarming device
Stretch state.When using alarming device provided by the invention, temperature sensor is made to pass through the opening of housing side and splicing fitting
Intimate surface contact, temperature sensor perceive the temperature of splicing fitting, when the temperature on splicing fitting surface is higher than early warning temperature, temperature-sensitive
Body crack damage, now portable plate loses support, and is moved under the contraction of spring to the direction close to fixed plate, until
In place, while portable plate can drive motion bar to move downward to spring contraction so that the body of rod of removable cover and piecemeal activity bar leads to
The bottom opening for crossing housing exposes in housing, and prompt band is similarly exposed in housing, and operations staff need to only see whether prompting
Band, which exposes, can determine that whether splicing fitting exceeds early warning temperature.
Compared with prior art, the beneficial effects of the invention are as follows：
Alarming device provided by the invention is perceived by temperature sensor to the temperature of splicing fitting, in the temperature of splicing fitting
When degree is higher than early warning temperature, temperature sensor crack damage, now expose prompt band by the control of corresponding mechanical structure, you can to carry
Show that the temperature of operations staff's splicing fitting exceeds early warning temperature.Alarming device provided by the invention has not affected by environment, survey
The advantages of accuracy of measurement is high.
Brief description of the drawings
Fig. 1 is the structural representation of alarming device before temperature sensor rupture.
Fig. 2 is the structural representation of alarming device after temperature sensor rupture.
Fig. 3 is the setting schematic diagram of lifting ear.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；
Below in conjunction with drawings and examples, the present invention is further elaborated.
Embodiment 1
As shown in figure 1, alarming device provided by the invention includes lateral opening and housing 1, the removable cover of bottom surface opening
2nd, the first motion bar 3, the second motion bar 4, the first spring 5, second spring 6, fixed plate 7, portable plate 8, prompt band 9 and temperature sensor
10；The fixed plate 7 is fixed in housing 1, and fixed plate 7 is fixedly connected with housing 1, offers through hole in the fixed plate 7, institute
State portable plate 8 and removable cover 2 is separately positioned on above and below fixed plate 7, portable plate 8 is arranged in housing 1, removable cover
Plate 2 covers to the bottom opening of housing 1, and removable cover 2 passes through fixed plate 7 by the first motion bar 3, the second motion bar 4
On through hole after be connected with portable plate 8, the first spring 5, the both ends of second spring 6, temperature sensor 10 both ends respectively with portable plate
8th, fixed plate 7 connects, and prompt band 9 is arranged on the first activity between the top surface or fixed plate 7 and removable cover 2 of removable cover 2
On the motion bar 4 of bar 3 and/or second.
In specific implementation process, the both ends of the temperature sensor 10 pass through a fixedly connected part 11 and portable plate respectively
8th, fixed plate 7 connects, and set location of the fixedly connected part 11 in portable plate 8, fixed plate 7 is respectively positioned at portable plate 8, fixed plate
