Description

But magnetic attraction retractable all-insulation prevents bird thorn

Technical Field

The invention relates to a bird-proof thorn, in particular to a magnetic-attraction retractable type full-insulation bird-proof thorn.

Background

In an electric power system, a power transmission and distribution line is used as an intermediate link for ensuring reliable power supply, the reliability of power supply has important influence on the reliability of power supply of the whole electric power system, birds are just the biggest harm on power transmission safety in the power transmission and distribution line, because birds have the characteristic of building bird nests on high-altitude trees for inhabitation, along with the development of a modernization process, tall trees are fewer and fewer, particularly, tall trees are rare in northwest areas due to climate reasons, so the birds usually look for some power transmission towers or telegraph poles to nest and inhabit at the tops of the power transmission towers or the telegraph poles, and branches and even iron wires can be used when the birds nest. When having foreign matter that iron wire etc. can be electrically conductive to drop to between two electrified bodies, can cause the overlap joint short circuit, the short circuit that discharges can take place for crowd birds when playing to fall, birds are piled up bird's excrement and are taken place insulator chain short circuit also after nesting.

At present, almost all bird-proof stabs used are made of metal materials, are limited in application range, can only be installed on a power transmission tower, cannot be installed on a distribution line with small distance, and are complex in installation, and once the bird-proof stabs fall onto a wire, the bird-proof stabs can also cause short circuit of the line.

Disclosure of Invention

The invention provides a magnetic-attraction retractable all-insulation bird-preventing thorn, which aims to solve the problems in the prior art.

But magnetism is inhaled full insulation of contraction type and is prevented bird thorn and include: the base is used for installation, the barbed wires extend out of the base in all directions, and the magnet is arranged at the center of the bottom of the base;

the barbed wire comprises a fixed barbed wire arranged on the upper layer and a rotatable barbed wire arranged on the middle layer and the lower layer, the outermost layer of the base is a semicircular arc-shaped top cover, a top cover central hole is formed in the center of the top cover, the fixed barbed wire penetrates through the top cover central hole, and strip-shaped grooves for limiting the opening position of the rotatable barbed wire are distributed in the top cover.

Furthermore, a first fixing seat, a second fixing seat and a third fixing seat are sequentially arranged below the top cover, a plurality of hemispherical grooves are uniformly distributed around the mutually contacted mounting surfaces of the first fixing seat, the two hemispherical grooves at corresponding positions form a spherical space, one end of the rotatable barbed wire with the ball head is mounted in the spherical space to form a spherical pair, and the fixed barbed wire is fixed at the top of the first fixing seat.

Furthermore, an open groove which only allows the rotatable barbed wire to pass through is formed outwards from the position of each hemispherical groove at the bottoms of the first fixed seat and the second fixed seat, and the rotatable barbed wire can only rotate the barbed wire along the direction of the open groove.

Furthermore, the middle layer rotatable barbed wire is arranged between the first fixing seat and the second fixing seat, and the lower layer rotatable barbed wire is arranged between the second fixing seat and the third fixing seat.

Further, the top cap passes through the draw-in groove to be connected with third fixing base buckle, and the bar groove on the top cap divide into rectangular groove and short strip groove, and wherein, the position one-to-one of rectangular groove and the position of the rotatable thorn silk of middle level, the position one-to-one of short strip groove and the rotatable thorn silk of lower floor.

Furthermore, the central positions of the magnet, the second fixing seat and the third fixing seat are provided with central holes through which countersunk bolts can pass, the first fixing seat is also provided with threaded holes, and the first fixing seat and the second fixing seat can be connected into a whole through bolts.

Furthermore, the part of each fixed thorn wire, which is close to the thorn tip, is provided with an anti-drop bead so as to prevent the top cover from dropping when the device is tightened.

Furthermore, the barbed wire is made of light, insulating and non-breakable glass fibers, and the first fixing seat, the second fixing seat and the third fixing seat are made of insulating materials, so that after the bird-proof barbed wire is installed, the exposed part is made of the insulating materials. The glass fibers are not easily broken and are elastic, so that birds cannot stably fall on the area covered by the barbed wires.

The invention has the technical effects that: the bulb end of rotatable thorn silk forms the sphere pair with the base subassembly, lets the thorn silk use the bulb to remove as the basic point in a flexible way, and open slot on first fixing base and the second fixing base makes rotatable thorn silk can only remove along the direction of opening or contracting, and the bar groove on the top cap divide into rectangular groove and short strip groove for the opening angle of restriction different level thorn silk lets all stretch out on the all directions of top cap and prevents bird thorn silk, avoids birds to be close to or nest near.

This prevent bird thorn portable opens the top cap, can let thorn silk stretching out that the direction is whole to be rotated up, and the shrink is swift, and during the installation, the thorn silk looses to the maximum angle of opening naturally under the action of gravity, aligns the thorn silk with the bar groove on the top cap and presses down, guarantees that the thorn silk is restricted in the position of opening, and thorn silk and installation base all use insulating material to make, and the installation back exposes all can't electrically conduct in the part that can contact, has higher security.
