Abstract
The utility model relates to a heating monitoring nut at a lead joint, which comprises a shell, an indicating rod, fixed bolts, a permanent magnet, a heat-sensitive ferrite, a spring, a human-insulating carbon fiber filler, a clamping bolt and an upper close cover, wherein the indicating rod and the spring are arranged in an upper cavity of the shell; one end of the spring is connected with the permanent magnet; the shell is clamped at the lead joint by the clamping switch; the indicating rod is clamped in the cavity by a bimetal strip; the heat-sensitive ferrite is fixed at one side of the indicating rod, close to an inner cavity wall; one end of the heat-sensitive ferrite is fixedly connected with the spring; the clamping bolt is arranged at the lower part of the upper cavity; two ends of the lower cavity of the shell are respectively and fixedly provided with the fixed bolts; and the carbon fiber filler is arranged in the lower cavity. The heating monitoring nut can cause the installation to be more convenient and faster, and the safety to be higher; in addition, as the clamping bolt is arranged, the protruding indicating rod can be clamped, therefore, the situation of missed checking caused by untimely checking of workers is avoided.
Description
Technical field
The utility model relates to the out-of-limit indicator of a kind of lead joint temperature, specifically a kind of lead joint heating monitoring nut.
Background technique
At present in power industry, have many kinds of temperature and get over line indicator, but all there is very big potential safety hazard basically, the major part of using during now life is produced all is the nut form of tightening, but tightening nuts form ground is the overlong time that hand contacts with nut in installation, there is very big danger in this in ultra-high-tension power transmission line, and can only use with supporting bolt matching, and Applicable scope is very little.
The model utility content
The purpose of this utility model is to address the above problem, heating monitoring nut in a kind of lead joint is provided, this temperature gets over that line indicator is placed on nut on the bolt when mounted and by the fixing bolt chucking, and owing to there is fixing bolt, makes the Applicable scope of nut become big.
The technical scheme in the invention for solving the technical problem is:
A kind of lead joint heating monitoring nut, comprise shell, indicating arm, fixing bolt, permanent magnet, heat sensitive ferrite, spring, exhausted people's filled with carbon fibers thing, screens bolt and upper cover, indicating arm and spring are arranged in the upper plenum of shell, spring one termination has permanent magnet, frame is stuck in the lead joint by the screens switch, indicating arm is stuck in the cavity by bimetallic strip, indicating arm is fixed with heat sensitive ferrite in the side near internal chamber wall, heat sensitive ferrite one end and spring are fixed, and a screens bolt is arranged at the bottom of upper plenum; The following cavity two ends of shell are respectively equipped with fixing bolt, are being provided with the filled with carbon fibers thing in the cavity down.
The beneficial effects of the utility model are: be fixed on the bolt of joint by fixing bolt by the staff during installation, can rotate fixing bolt during unloading takes off nut, this just makes installation more convenient quick, Security is higher, in addition, there is the screens bolt, can blocks the indicating arm that stretches out, avoided the staff to check the omission situation that causes when untimely like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 shell, 2 indicating arms, 3 springs, 4 permanent magnets, 5 heat sensitive ferrites, 6 fixing bolts, 7 filled with carbon fibers things, 8 upper covers, 9 screens bolts.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, it comprises shell 1, indicating arm 2, spring 3, permanent magnet 4, heat sensitive ferrite 5, fixing bolt 6, filled with carbon fibers thing 7, upper cover 8 and screens bolt 8.Installation personnel places nut on the bolt of installation position when installing, and fixing by fixing bolt 6, fills with filled with carbon fibers thing 7 in the gap.Described indicating arm 2 is to be placed in the upper plenum of shell 1 formation, one end is indicating arm 2 outlets, one end is fixed with heat sensitive ferrite 5, the other end of heat sensitive ferrite 5 and spring 3 are affixed, spring 3 the other ends are connected on the permanent magnet 4 that is built in cavity, the permeability of heat sensitive ferrite 5 changes 60,70,80 degrees centigrade are not waited, can select different heat sensitive ferrites to adapt to different line temperature more, permanent magnet 4 attracts indicating arms 2 and pressure springs 3 when not surpassing more the line temperature, make in the indicating arm 2 indentation cavitys, when temperature surpasses qualification, the permeability of heat sensitive ferrite 5 changes, indicating arm 2 is ejected by spring 3, scribbling eye-catching color on the indicating arm 2 can remind the inspector to find danger timely, the indicating arm that ejects when not having the inspection personnel is blocked so that warn when the procurator is arranged by screens bolt 9, has avoided the staff to check the omission situation that causes when untimely, has improved the accuracy of work effectively.
