Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings and examples.
The embodiment of the utility model provides a: join in marriage net electric pole initiative safety device's structural schematic diagram as shown in fig. 1 ~ 3, including shear bolt 1, nut 2, go up gland 3, fixer 6 and staple bolt 7, threaded hole 8 is seted up at the top of fixer 6, threaded connection has shear bolt 1 on threaded hole 8, the cover has last gland 3 on shear bolt 1, and go up gland 3 and can follow shear bolt 1 axis direction and adjust, there is nut 2 at shear bolt 1's upper end threaded connection, be provided with staple bolt 7 in the below of fixer 6, staple bolt 7's both sides pass through connecting band and fixer 6 fixed connection.
The protective device further comprises an insulating protective shell 11, and the shearing bolt 1, the nut 2, the upper gland 3, the fixer 6 and the hoop 7 are all arranged in the insulating protective shell 11. Referring to fig. 5, the insulating protection housing 11 includes two U-shaped housings symmetrically disposed, semicircular clamping holes are symmetrically formed in the bottoms of the two U-shaped housings, the two semicircular clamping holes can be just clamped at the minimum outer diameter of the insulator 9, and a self-locking strap 12 is sleeved outside the two U-shaped housings.
When the active safety protection device for the distribution network pole is installed, firstly, the fixing device 6 is sleeved on the insulator 9 at the top of the pole and is fixed with the insulator 9 through the hoop 7, then the shearing bolt 1 is in threaded connection with the threaded hole 8 at the top of the fixing device 6, and then the end parts of the left circuit 4 and the right circuit 5 are fixed on the shearing bolt 1; referring to fig. 4, the ends of the left and right wires 4 and 5 are fixed by a wire ferrule 10. At this moment, the upper gland 3 is sleeved on the shearing bolt 1, the nut 2 is screwed into the upper end of the shearing bolt 1, the upper gland 3 is pressed through the nut 2 to move downwards until the upper gland 3 tightly presses the end parts of the left circuit 4 and the right circuit 5, and finally the whole device is sleeved in the insulating protection shell 11. In the device, the left line 4, the right line 5 and the insulator 9 are of a self-contained structure of the distribution network line.
When the insulation protection shell 11 is installed, the semicircular clamping holes at the bottoms of the two U-shaped housings are clamped on the insulator 9, and then the two U-shaped housings are fixed together through the self-locking type strap 12.
The utility model discloses a mechanism of operation: under normal conditions, the acting force of the left line 4 and the right line 5 on the shear bolt 1 is smaller than the shear strength of the left line and the right line; when the power transmission line is subjected to strong external force such as tree lodging and extreme weather, the external force acts on the shearing bolt 1 through the left line 4 and the right line 5, if the force reaches the shearing strength threshold value of the shearing bolt 1, the shearing bolt 1 is sheared, fracture damage occurs, the left line 4 and the right line 5 connected to the shearing bolt 1 are separated immediately, the strong external force can be released, and the electric pole inclination or pole breakage accident is avoided.
The utility model discloses applicable different specification (diameter) circuit can satisfy the demand of different model poles. Meanwhile, the damage threshold value of the shear bolt 1 can be changed by producing the shear bolt 1 with different specifications according to the maximum bearable external force of different lines, so that the damage limit of different electric poles is adapted, and the purpose of protecting the electric poles is achieved. When the shear bolt 1 is damaged and the line is required to be installed again after being separated from the device, the shear bolt 1 is only required to be replaced and fixed on the fixer 6, and then the line is wound and compacted to complete repair, so that the repair process is simple and efficient.
