Description
Technical field
The utility model relates to bolt field more particularly to a kind of transmission line of electricity tower bar high temperature alarm bolts.
Background technique
In the event of a failure, the temperature of abort situation can rise transmission line of electricity tower bar, cause damages, currently, needle not yet
To the high temperature alarm bolt of transmission line of electricity tower bar design.
Utility model content
Purpose of utility model: in view of the deficiencies of the prior art with defect, the utility model provides a kind of by different heat expansions
The bimetallic strip of contraction coefficients carries out the closure in alarm lamp circuit or the transmission line of electricity tower bar high temperature alarm bolt of disconnection.
Technical solution: the transmission line of electricity tower bar high temperature alarm bolt of the utility model, it is characterised in that: including the body of bolt
And it is equipped with embedded area and embedded area bottom at the nut of the body of bolt and is equipped with ambroin matter pedestal；It is equipped with above the pedestal exhausted
Edge plastics matter secondary station is simultaneously equipped with bimetallic strip and bimetallic strip by two kinds of systems differences of expanding with heat and contract with cold above secondary station
Sheet metal composition and bimetallic strip both ends end be equipped with vertical metallic rod；The upper layer sheet metal of the bimetallic strip
Coefficient of thermal expansion and contraction be greater than lower metal piece coefficient of thermal expansion and contraction；The metallic rod bottom is located at pedestal side and in pedestal
Side is equipped with corresponding sheet metal；It is successively connect with battery, alarm lamp and lamp position of alarming between 2 sheet metals by conducting wire
In the nut surface of the body of bolt.
Wherein, the embedded area is equipped with transparent ambroin lid.
Wherein, the bimetallic strip is made of copper sheet and iron plate, and upper layer is copper sheet and lower layer is iron plate.
Wherein, the bimetallic strip above bonding material and secondary station by connecting.
Wherein, the metallic rod bottom is equipped with spherical contact.
The utility model has the advantages that compared with prior art, the utility model has following remarkable advantage: the utility model is for defeated
The electric line tower bar easily place of breaking down is easy to produce the high temperature alarm bolt that high temperature damages design, is expanded with heat and contract with cold by difference
The bimetallic strip of coefficient carries out the closure or disconnection in alarm lamp circuit, easy to operate, easy to use.
Detailed description of the invention
Fig. 1 is the vertical cross-section structural schematic diagram of the utility model；
Fig. 2 is the transversal cross-section structural schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is further described the technical solution of the utility model.
The transmission line of electricity tower bar high temperature alarm bolt of the utility model, including the body of bolt 1 and at the nut of the body of bolt 1
Equipped with embedded area 2 and embedded 2 bottom of area is equipped with ambroin matter pedestal 3；Ambroin matter secondary station 4 is equipped with simultaneously above pedestal 3
Bimetallic strip 5 is equipped with above secondary station 4 and bimetallic strip 5 is made of simultaneously two kinds of different sheet metals of system of expanding with heat and contract with cold
Vertical metallic rod 6 is equipped in 5 both ends end of bimetallic strip；The coefficient of thermal expansion and contraction of the upper layer sheet metal of bimetallic strip 5
Greater than the coefficient of thermal expansion and contraction of lower metal piece；6 bottom of metallic rod is located at 3 side of pedestal and is equipped in 3 side of pedestal corresponding
Sheet metal 7；It is successively connect with battery 8, alarm lamp 9 between 2 sheet metals 7 by conducting wire and alarm lamp 9 is located at the spiral shell of the body of bolt 1
Cap surface.Wherein, it embeds area 2 and is equipped with transparent ambroin lid；Bimetallic strip 5 is made of copper sheet and iron plate, and upper layer is
Copper sheet and lower layer are iron plate；Bimetallic strip 5 above bonding material and secondary station 4 by connecting；6 bottom of metallic rod is equipped with spherical shape
Contact.
In use, the transmission line of electricity tower bar that is mounted on of the utility model is easily broken down place, when in the temperature that breaks down
When rising, system is different, and bimetallic strip 5 is bent downwardly since 2 sheet metals expand with heat and contract with cold for bimetallic strip 5, drives metallic rod 6
It deviating inwardly, 6 bottom of metallic rod is connect with sheet metal 7, then, battery 8, alarm lamp 9, sheet metal 7, metallic rod 6, the double-deck gold
Belong to piece 5, metallic rod 6, sheet metal 7, battery 8 to be formed into a loop, battery 8 is powered to alarm lamp 9, and alarm lamp 9 lights, and prompts temperature
Spend height.
When perhaps temperature belongs to zone of reasonableness to natural temperature, bimetallic strip 5 is not bent or bending degree is little, gold
Belong to 6 bottom of bar to separate with sheet metal 7, form open circuit, battery 8 cannot power to alarm lamp 9, and alarm lamp 9 is in OFF state.This
The high temperature alarm bolt of sample is easy to operate, easy to use.
