Description
Technical field
The utility model relates to a kind of temperature indicating device, relates in particular to a kind of temperature alarming nut.
Background technology
The transmission line wire long-term work is under the operating mode of big load, big electric current, because Effect of Environmental such as grey greasy dirt makes that connecting portion resistance increases, temperature raises in the oxidation of terminal place metal and the air.Work long hours under the condition of high temperature, not only influence the serviceable life of lead also can initiating failure and cause serious electric power accident.According to statistics current power transmission line wire fault more than 80% because lead annex fault causes that wherein the fault that causes of terminal accounts for over half.
The temperature parameter of transmission line wire when work is most important, grasps the variation of connector temperature, just can in time find potential faults.At present the main method of detection tabs temperature is hand-held infrared detector, and its main weak point is can not the continuous detecting connector temperature, in time finds temperature variations, and its accuracy of detection is easily received Effect of Environmental in addition.
The patent No. is that the utility model patent of ZL 200720121508.2 discloses the out-of-limit indication bolt of a kind of temperature, this bolt is installed on the joint of transmission line wire, and transmission line wire monitored in real time in the temperature in when work, when the transmission line wire temperature reaches limit value, bolt then can be made the caution action by spring, can effectively avoid the fault and the accident that cause because of the joint overtemperature.But the out-of-limit indication bolt of the temperature of this kind structure is the butterfly shaped dual metal sheet of bolt inside to be warned head with inner core directly link to each other, at long high pressure, under the user mode of high electric current, thorough deformation takes place in butterfly shaped dual metal sheet easily, added in air oxidation and the air under the Effect of Environmental such as grey greasy dirt and made that the out-of-limit indication bolt reaction of temperature is insensitive, precision reduces gradually, can not play the effect of real-time detection, does not fundamentally solve the joint overtemperature and the fault and the accident that cause.
The utility model content
In order to solve the above-mentioned technical matters that exists in the background technology, the utility model provide a kind of highly sensitive, stability is strong, easy to use, the temperature alarming nut of long service life.
Technical solution of the present utility model is: the utility model provides a kind of temperature alarming nut, comprises housing, caution head and dish-shaped sheet metal; Housing sidewall is provided with can be for the outlet of caution head turnover, and enclosure interior is provided with a cavity, and described cavity and outlet integral body are the C type; End away from outlet in the C die cavity is provided with spring, and described caution head is arranged in the C die cavity by spring, and its special character is: described dish-shaped sheet metal is fixed in enclosure interior; End away from outlet on the described dish-shaped sheet metal is provided with bolt; Described caution head is provided with groove or ditch, and described bolt is stretched in the groove of warning on the head or ditch.
Above-mentioned enclosure interior also is provided with gripping mechanism near an end of outlet, and described gripping mechanism is stretched in the groove of warning on the head or ditch.
Above-mentioned gripping mechanism is screw or key.
Above-mentioned case top is provided with top groove, and described dish-shaped sheet metal is arranged in the top groove.
Above-mentioned dish-shaped sheet metal is to be fixed in the top groove by screw.
Above-mentioned case top also is provided with the lid suitable with top groove.
The lid of above-mentioned case top and top groove are to be threaded or clamping.
Above-mentioned housing bottom is provided with bottom groove.
Also be provided with the aperture that communicates with bottom groove on the above-mentioned housing.
The transversal section of above-mentioned housing is hexagonal.
The utility model has the advantages that:
1, highly sensitive, stable strong.The utility model is arranged dish-shaped sheet metal and inner core caution head branch, in use, under the operating mode of big load, big electric current, thorough deformation can not take place because of contacting with inner core caution head for a long time in the dish sheet metal, dish-shaped sheet metal and housing directly join simultaneously, and sensitivity significantly improves; The utility model dish sheet metal when work need not and first slip of inner core caution, has reduced wearing and tearing, has improved reliability, the stability of the number of times of its use.
2, easy to use.The utility model when mounted, can be according to the situation at scene, the utility model is arrived adjusting angle arbitrarily, by being arranged on the aperture on the utility model, be fixed then with screw, simultaneously, the utility model adopts hexgonal structure, need not to adopt special erecting tools, directly with manually just finishing loading and unloading, the convenient installation, easy to use.
3, long service life.The utility model adopts modular construction, if any part damages, only needs to change wherein a part and just can use fully, and do not need to change whole temperature alarming nut, has saved cost of manufacture, and has made increase serviceable life.
