Description

Technical Field

[0001] The present invention relates to an anti-bird thorn, and particularly to a magnetically attracted retractable fully insulated anti-bird thorn. Background Art

[0002] In the power system, the power transmission and distribution lines, as the intermediate links to ensure reliable power supply, have an important impact on the power supply reliability of the entire power system. Among the factors affecting power transmission safety in the power transmission and distribution lines, birds are the greatest hazard. Because birds have the characteristic of building nests and perching on tall trees at high altitudes. With the development of the modernization process, the number of tall trees is decreasing. Especially in the northwest region, due to climatic reasons, the number of tall trees is even scarcer. Therefore, birds usually look for some transmission towers or electric poles to build nests and perch on their tops. When birds build nests, they will use some branches or even iron wires. When foreign objects such as iron wires that can conduct electricity fall between two live conductors, it will cause a short circuit due to connection. When flocks of birds take off and land, discharge short circuits will occur. After birds build nests, the accumulation of bird droppings will also cause a short circuit of the insulator string.

[0003] Almost all of the currently used anti-bird thorns are made of metal materials, with limited application scope. They can only be installed on transmission towers and cannot be installed on distribution lines with a small phase distance. Moreover, the installation is cumbersome. Once an anti-bird thorn falls onto the wire, it may also cause a short circuit of the line. Summary of the Invention

[0004] The present invention proposes a magnetically attracted retractable fully insulated anti-bird thorn to solve the problems existing in the prior art.

[0005] The magnetically attracted retractable fully insulated anti-bird thorn includes: a base for installation, thorn wires extending from the base in all directions, and a magnet provided at the center of the bottom of the base;

[0006] The thorn wires include fixed thorn wires arranged in the upper layer and rotatable thorn wires arranged in the middle and lower layers. The outermost layer of the base is a semi-circular top cover. There is a top cover center hole at the center of the top cover. The fixed thorn wires pass through the top cover center hole. Bar-shaped grooves for restricting the opening position of the rotatable thorn wires are evenly distributed on the top cover.

[0007] Further, a first fixing seat, a second fixing seat, and a third fixing seat are sequentially arranged below the top cover. A number of hemispherical grooves are evenly distributed around the contact mounting surfaces of the three. Two corresponding hemispherical grooves form a spherical space. One end of the rotatable thorn wire with a ball head is installed in the spherical space to form a spherical pair. The fixed thorn wires are fixed on the top of the first fixing seat.

[0008] Furthermore, an opening slot is opened outward from the position of each hemispherical groove at the bottom of the first fixing seat and the second fixing seat, which only allows the rotatable barbed wire to pass through, and the rotatable barbed wire can only be rotated along the direction of the opening slot.

[0009] Furthermore, the middle layer of rotatable barbed wire is arranged between the first fixing seat and the second fixing seat, and the lower layer of rotatable barbed wire is arranged between the second fixing seat and the third fixing seat.

[0010] Furthermore, the top cover is snap-connected to the third fixing seat via a card slot, and the strip slots on the top cover are divided into long slots and short slots, wherein the positions of the long slots correspond one-to-one to the positions of the middle-layer rotatable barbed wires, and the positions of the short slots correspond one-to-one to the positions of the lower-layer rotatable barbed wires.

[0011] Furthermore, the center positions of the magnet, the second fixing seat, and the third fixing seat are all provided with center holes through which countersunk bolts can pass, and the first fixing seat is also provided with threaded holes, so that the above components can be connected into one by bolts.

[0012] Furthermore, each fixed barbed wire is provided with an anti-falling bead near the barb tip to prevent the top cover from falling off when the device is tightened.

[0013] Furthermore, the barbed wire is made of light, insulating, and unbreakable glass fiber, and the first fixing seat, the second fixing seat, and the third fixing seat are all made of insulating materials, so that after the anti-bird barb is installed, the exposed part is made of insulating material. The glass fiber is not easy to break and is elastic, so that the bird cannot stably land on the area covered by the barbed wire.

[0014] The technical effect of the present invention is that the ball head end of the rotatable barbed wire forms a spherical pair with the base assembly, allowing the barbed wire to move flexibly with the ball head as the base point, and the open grooves on the first fixed seat and the second fixed seat enable the rotatable barbed wire to move only in the direction of opening or contraction. The strip grooves on the top cover are divided into long strip grooves and short strip grooves, which are used to limit the opening angles of barbed wires at different levels, so that bird-proof barbed wires can be extended in all directions of the top cover to prevent birds from approaching or nesting nearby.

[0015] The bird-proof thorn is easy to carry. When the top cover is opened, the extending direction of the barbed wire can be turned upward, and it can be retracted quickly. When installing, the barbed wire will naturally spread to the maximum opening angle under the action of gravity. The strip groove on the top cover is aligned with the barbed wire and pressed down to ensure that the barbed wire is restricted in the open position. The barbed wire and the installation base are made of insulating materials. After installation, the exposed and contactable parts cannot conduct electricity, which has higher safety.

[0020] The following combines with Figures 1 to 3 to illustrate the specific embodiments of the present invention.

[0021] Figure 1 Schematically shows the assembly sequence and structural features of each component part of the anti-bird spike. The anti-bird spike includes: a base 1 for installation, barbed wires 2 extending from the base in all directions. The barbed wires 2 include fixed barbed wires 21 arranged in the upper layer and rotatable barbed wires 22 arranged in the middle and lower layers. The outermost layer of the base 1 is a semi-circular top cover 11. A center hole 114 of the top cover is provided at the center of the top cover 11. The fixed barbed wires 21 pass through the center hole 114 of the top cover. Strip-shaped grooves 111 for restricting the opening position of the rotatable barbed wires 22 are evenly distributed on the top cover 11;

[0022] An open slot 121 allowing only the rotatable barbed wire 22 to pass through is opened outward from the position of each hemispherical groove 30 at the bottoms of the first fixing seat 12 and the second fixing seat 13. The top cover 11 is snap-connected to the third fixing seat 14 through a card slot 15. The strip-shaped grooves 111 on the top cover 11 are divided into long strip-shaped grooves 112 and short strip-shaped grooves 113. Among them, the positions of the long strip-shaped grooves 112 correspond to the positions of the rotatable barbed wires 22 in the middle layer one by one, and the positions of the short strip-shaped grooves 113 correspond to the positions of the rotatable barbed wires 22 in the lower layer one by one. Anti-disengagement beads 211 are provided at the parts of each fixed barbed wire 21 close to the barbed tips to prevent the top cover 11 from falling off when the device is tightened.

[0023] Figure 2 and Figure 3It shows the internal structure after the anti-bird spikes are assembled into one. A magnet 3 is arranged at the center of the bottom of the base 1. Below the top cover 11, a first fixing seat 12, a second fixing seat 13, and a third fixing seat 14 are successively arranged. A number of hemispherical grooves 30 are evenly distributed around the contact mounting surfaces of the three. Two corresponding hemispherical grooves 30 form a spherical space. One end of the rotatable barbed wire 22 with a ball head 221 is installed in the spherical space to form a spherical pair. The fixed barbed wire 21 is fixed on the top of the first fixing seat 12. An opening groove 121 that only allows the rotatable barbed wire 22 to pass through is opened outward from the position of each hemispherical groove 30 at the bottoms of the first fixing seat 12 and the second fixing seat 13. The middle-layer rotatable barbed wire 22 is arranged between the first fixing seat 12 and the second fixing seat 13, and the lower-layer rotatable barbed wire 22 is arranged between the second fixing seat 13 and the third fixing seat 14;

[0024] Central holes through which countersunk bolts can pass are provided at the central positions of the magnet 3, the second fixing seat 13, and the third fixing seat 14. A threaded hole is also provided on the first fixing seat 12. Bolts can be used to connect the above-mentioned components into one body.

[0025] Working principle: When carrying, pull up the top cover 11. Since it is sleeved on the fixed barbed wire 21 through the central hole 114 of the top cover, as the top cover 11 is pulled up, the fixed barbed wires 21 gather towards each other, and the other rotatable barbed wires 22 can gather towards the center along the direction of the opening groove 121, making the whole anti-bird spike easy to carry.

[0026] When installing, align the long slot 112 and the short slot 113 on the top cover 11 with the lower-layer rotatable barbed wire 22 and the middle-layer rotatable barbed wire 22 respectively, and press down the top cover 11 to make the top cover stuck on the card slot 15 of the third fixing seat 14; the fixed barbed wire 21 unfolds outward due to the loss of restraint, and the rotatable barbed wire 22 is restricted to a fixed unfolded position due to the interaction between the opening groove 121 and the strip groove 111. Place the anti-bird spike in the place where bird prevention is needed, and the magnet 3 at the bottom can quickly adsorb and fix it.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
