Description

{INTERCEPTION APPARATUS FOR PREVENTING VINES AND SNAKES FROM CLIMBING OF GUY WIRE}

The present invention relates to a vine and snake climbing prevention device for branch wires that prevents vines or snakes from climbing up a branch wire that reinforces a utility pole on the ground. More specifically, it relates to a vine or snake climbing prevention device that prevents vines or snakes from climbing up a branch wire that reinforces a utility pole on the ground. This relates to a vine and snake climbing prevention device for branch lines that not only lowers the wind, but also increases the rotational force caused by the wind, so that it rotates smoothly without getting caught in tangled vines, and is also designed to be easily and firmly installed on branch lines.

In general, wire ropes (wire ropes supporting electric poles, guy wires) are support lines that prop up the electric pole at an angle above the ground to prevent it from falling over due to the tension of the electric wire or the wind. In particular, in the case of ordinary branch lines (inhumane branch lines), one end is a branch wire. It is connected to the end of the electric line or the top of the electric pole using a band, and the other end is fixed to a stay block buried in the ground through a stay rod, and the installation angle with the electric pole is usually 30 degrees. It is formed at ~45 degrees.

Meanwhile, a vine wraps around a branch wire and climbs up the electric pole that supports an overhead distribution line, or a snake winds around a branch wire with a lateral wave motion using the reverse scale texture across its entire abdomen to eat eggs or young in the nest above the electric pole. When riding up, there is a problem that various accidents such as short circuits, electric leaks, and power outages frequently occur due to contact with high-voltage power lines and other power facilities.

As a related conventional technology, in Patent Document 1, a snake and vine climbing prevention device for electric pole branch wires, which can prevent vines or snakes from climbing up electric poles while wrapping around branch wires, has been disclosed.

That is, Patent Document 1 is composed of a first wing part 120, a branch line installation part 110, a second wing part 130, and a lower side fixing part 150, as shown in FIG.

However, this causes the vines to wrap between the first and second wing parts 120 and 130 and the lower fixing part 150 and become tightly entangled, and in this case, the first wing part 120 and the second wing part 130 ) is caught in the vine and cannot rotate, so there is a problem in that the vine easily wraps around the first wing portion 120 and the second wing portion 130.

To solve this problem, a vine climbing prevention device for preventing vines from getting caught has been disclosed in Patent Document 2.

That is, Patent Document 2, as shown in FIG. 2, includes first and second wing parts 120 and 130 rotatable about the branch wire 20 and a fixing part fixed to the branch wire 20 to support them ( 140) By forming a gap between the vines, the vines cannot naturally shake or slide down and wind up around the first and second wings 120 and 130, which causes the vines to move between the first and second wings. Since it is not tightly wound around the parts 120 and 130, the first and second wing parts 120 and 130 can rotate smoothly without being interrupted by vines when the wind blows.

However, since this is a structure that rotates when wind hits the first and second wings 120 and 130, there is a limit to the rotational force being significantly reduced.

In addition, there is a problem that it is very difficult to firmly install the fixing part 150 on the branch wire 20 due to its structural characteristics in that it maintains its fixed state by simply generating friction with the branch wire 20 by the tightening force of bolts and nuts.

Moreover, during the process of installing the fixing parts 150 on the branch line, they are offset from each other and fixed at a step, and as a result, the lower end of the branch line installation part 110 in contact with the fixing part 150 gets caught on the protrusion of the fixing part 150 when it rotates. There is a problem in that it does not rotate smoothly.

In other words, the branch line installation part 110 is cut so that one side can be opened for installation by inserting it into the outer circumference of the branch line (G), and has a branch wire insertion part 112 to block the gap in the cut part. When (110) rotates due to wind, the branch wire insertion part (112) is twisted and caught on the protrusion of the fixing part (150), causing contact interference, which not only significantly reduces the rotational force, but also causes deformation and damage in severe cases.

The background or prior art described above herein is information possessed by the present inventor or acquired in the process of deriving and completing the present invention, and is merely indicated to help understand the technical significance of the present invention and to be useful in prior art search and examination. , it is clarified that it does not mean a technology generally known and widely used in the technical field to which the invention pertains before the application of the present invention, and in addition, the reference numerals in the prior art are unrelated to the reference numerals in the present invention.

Accordingly, the present inventor comprehensively considered all of the above-mentioned matters and at the same time, with the idea of solving the technical limitations and problems of the existing vine climbing prevention device technology, when a vine or snake tries to climb up, it slides down easily and naturally so that it is kept on the ground. By winding the branch line, it not only has the effect of preventing it from climbing around the iron pole that supports the overhead distribution line by riding the electric pole, but also increases the rotational force caused by the wind, so that it rotates smoothly without getting caught in the vines, and also prevents the branch line from getting caught in the vines. We strived to develop a vine and snake climb prevention device for branch lines with a new structure that can be installed simply and robustly and can be used for general purposes by adjusting the width to suit various vines and snakes of different sizes depending on the characteristics of the region or climate. As a result of continuous research with great effort, the present invention was created.

Therefore, the technical problem and purpose to be solved by the present invention is to provide a vine and snake climbing prevention tool for branch lines that allows vines or snakes to easily slip down and increase rotational force due to the wind.

Another technical problem and purpose to be solved by the present invention is to provide a vine and snake climbing prevention device for branch lines that can be easily and firmly installed on branch lines.

Another technical problem and purpose to be solved by the present invention is to provide a vine and snake climbing prevention tool for branch lines that can be used universally by adjusting the width according to the characteristics of various regions or climates.

Here, the technical problems and objectives to be solved by the present invention are not limited to the technical problems and objectives mentioned above, and other technical problems and objectives not mentioned can be understood from the description below as a matter of common knowledge in the technical field to which the present invention pertains. Those who have it will be able to understand it clearly.

A specific means according to the aspect of the present invention for effectively achieving a specific technical purpose while embodying a new idea for solving the technical problem of the present invention as described above is to surround the branch line at the center. A long cylindrical sleeve is formed to be inserted into the outer circumference, and a vine or snake is wound around both sides along the longitudinal direction of the sleeve, causing it to slide down and rotating around the branch line with the force of the wind. 2. A vane is formed by protruding and is inserted into and fixed to the outer periphery of the branch wire, a support shaft is formed at the upper center to be inserted into the bottom hole of the sleeve, and a contact surface abutting the sleeve is formed at the lower part of the support shaft so that the blade rotates. A vine and snake climbing prevention tool for branch wires is presented, which includes a holder that supports the blade as much as possible, and is characterized in that a gap is formed to separate the first and second vanes of the blade from the holder.

As a result, the present invention has the effect of ensuring that vines or snakes slide down easily and naturally when trying to climb up a branch line from the ground, thereby preventing them from climbing up the electric pole and around the wire supporting the overhead distribution line.

In addition, in a preferred aspect of the present invention, the lower ends of the first and second vanes have an upward slope from the sleeve to the outer side of each, and face the lower ends of the first and second vanes. The upper surface of the holder has a downward slope from the support axis to the edge, so that the vines cannot wind up and naturally shake and do not become tightly entangled, so it can rotate smoothly without being caught in the vines when the wind blows.

In addition, in a preferred aspect of the present invention, the holder is formed by dividing the first and second holders equally and forming the same vertical symmetry to the left and right about the vertical axis of the center so as to be wrapped and fixed on both sides with the branch line in between. It is made of a holder, and the dividing surfaces of the first and second holders are tightly adhered to each other with the branch wire between them as if wrapped on both sides, and when fixed, the mutual coupling position is determined so that the contact surfaces are on the same plane. Positioning holes and positioning pins are formed respectively, and tightening parts with through holes are formed on both sides of the first and second holders, and the spacing gradually widens outward on the dividing surfaces of the tightening parts facing each other. By forming an inclined surface, a bolt is driven through the through hole and a nut is tightened on the other side. When fastened, the tightening part is elastically deformed by the friction force caused by the tightening force of the bolt and the nut, and the bolt and the By increasing the friction of the nut, it prevents loosening, which allows for simpler and more robust installation on branch lines.

In addition, a preferred aspect of the present invention is that brims are formed on the outer side edges of the first and second vanes to respectively reinforce strength and allow the vine to slide down, and the first and second vanes are formed at the top. It is formed in an inverted trapezoidal shape with a width gradually narrowing from the bottom to the bottom, and the area of the second vane is formed to be wider than the area of the first vane, so that in normal times when there is no wind, the second vane is where the center of gravity of the blade is located. It turns toward the ground around the branch line and is erected toward the electric pole to prevent vines or snakes from winding up or climbing on the surface of the first and second vanes.

In addition, a preferred aspect of the present invention is that the first and second vanes are each bent in a curved shape, and each of the divided surfaces of the first and second holders is located at a corner portion that meets the contact surface at the bottom of the sleeve. By forming a chamfer that prevents the blade from getting caught during rotation, the rotation speed of the blade is increased and the rotational force caused by the wind is increased, allowing it to rotate more smoothly without getting caught in the vine.

In addition, a preferred aspect of the present invention is that tracks are formed to protrude at a certain width on both sides along the longitudinal direction of the sleeve, and are formed at regular intervals on the inner surfaces of the longitudinal grooves, and are formed at regular intervals by the elastic action of the tracks. Pollocks that spread outward are formed to protrude at regular intervals from the inner ends of the first and second vanes, respectively, and the position within the longitudinal groove of the track is determined by the biting action of the polelocks to determine the first vane. And it further includes a ratchet that adjusts the installation width of the second vane, so that the installation width of the first and second vanes can be freely adjusted, and the width can be adjusted to suit the characteristics of vines or snakes of different sizes depending on the region or climate. Can be used universally.

According to an embodiment that implements the technical idea on which the unique solution is based to solve the technical problem of the present invention, a gap is formed between the first and second vanes of the blade and the holder, so that the vine When a snake or snake tries to climb up a branch wire on the ground, it easily slips down, and in particular, it prevents the vines from winding up and naturally shaking and becoming tightly entangled, so that when the blade turns with the power of the wind, it can rotate smoothly without getting caught in the vines.

Therefore, it reliably prevents vines or snakes from climbing up the branch line to the electric pole and prevents accidents such as short circuits, electric leaks, and power outages from coming into contact with power facilities, including the power lines at the top of the pole.

In addition, the worker can easily and firmly fix the holder to the branch wire by turning and tightening the bolts and nuts by hand. In this process, the tightening part of the holder is elastically deformed due to the friction caused by the tightening force of the bolt and nut, creating a spring action (repulsion force). This increases the friction of the bolt and nut, preventing loosening.

Moreover, the first and second vanes are each bent in a curved shape, and the joining positions are determined on the dividing surfaces of the first and second holders facing each other, so that the contact surfaces do not misalign with each other and form a smooth same plane. A crystal hole and a positioning pin are formed, and a chamfer is formed on the corner of the dividing surface of the first and second holders that meets the contact surface, which not only facilitates the flow of air, but also prevents the bottom of the sleeve from getting caught in the holder when rotating. By increasing the rotation speed of the blade, the rotational force caused by the wind can be increased, and this allows the blade to rotate more smoothly without being caught in vines.

In addition, the operator can freely adjust the installation width of the first and second vanes depending on the installation area or climate, so it can be used universally to suit the characteristics of various vines or snakes.

In other words, it can be used universally by adjusting the width to suit the characteristics of vines or snakes of different sizes depending on the region or climate, thereby maximizing convenience and efficiency as well as functionality and usability, thereby increasing economic efficiency and product differentiation. This can enhance the convenience of use, including improving marketability.

Here, the effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

<Specific Embodiment>

The main elements constituting the vine and snake climbing prevention equipment for branch lines according to an embodiment of the present invention largely include a blade 10 and a holder 20, as shown in FIGS. 3 to 10.

The blade 10 is fixed to the branch wire G by a holder 20, and at its center is formed a long cylindrical sleeve 11 that is inserted into the outer periphery of the branch wire G so as to surround the branch wire G.

And on both sides along the longitudinal direction of the sleeve 11, there are first and second vanes 12 that cause vines or snakes to slide down when trying to wind up and rotate with the force of the wind around the branch line G. (13) is formed by protruding.

In addition, a gap is formed between the first and second vanes 12 and 13 and the holder 20 at a regular interval.

In addition, the lower ends of the first and second vanes 12 and 13 are formed at an angle with an upward slope from the sleeve 11 toward their respective outer sides to prevent vines from rolling up.

And the first and second vanes 12 and 13 are formed in an inverted trapezoidal shape whose width gradually narrows from the top to the bottom.

In addition, the area of the second vane 13 is formed to be wider than the area of the first vane 12.

That is, the first vane 12 and the second vane 13 are formed asymmetrically with different shapes at the top and bottom centered on the sleeve 11.

And the first and second vanes 12 and 13 are each curved to increase the rotation speed of the blade 10.

In addition, the outer upper and lower corners of the first and second vanes 12 and 13 are rounded.

In addition, in order to forcibly open one side of the sleeve 11 and insert it into the branch wire G, the part of the side of the sleeve 11 that is in contact with the second vane 13 is cut along its length, and the cut part has 2. A closure portion 11a is formed that maintains close contact with the inner edge of the vane 13 and prevents gaps.

Here, the thickness of the first and second vanes 12 and 13 is about 0.5 mm to 5 mm to ensure flexibility and hardness that does not break easily, and the length is 0.5 m to minimize the influence of the type of vine and the size of the snake. It is preferably formed to about 3 m.

In addition, it is preferable that the lower ends of the first and second vanes 12 and 13 are inclined at about 20 to 60 degrees.

In addition, the surfaces of the first and second vanes 12 and 13 may be processed separately to maximize the appearance (prevention of discoloration) and the sliding effect of vines and snakes.

The holder 20 is fixed by inserting it into the outer circumference of the branch wire (G) to support the blade 10 so that it can rotate freely 360 degrees. It is formed in a hollow shape, and is attached to the bottom hole of the sleeve 11 at the upper center thereof. A long cylindrical support shaft 21 is formed to protrude upward and downward.

And, on the outer circumference of the support shaft 21, a plurality of ring bearings 21a are formed at regular intervals to reduce friction through point contact when the blade 10 rotates.

In addition, a contact surface 22 that comes into contact with the sleeve 11 is formed to protrude around the lower end of the support shaft 21.

In addition, the holder 20 has an inclined surface slanted downward from the contact surface 22 so that it easily slides down when the vine tries to roll up.

For example, the holder 20 may have a shape and form in which the support shaft 21 is integrally formed on the upper surface of a cone-shaped hollow tube.

In addition, in order to make it difficult for the vine to roll up, the holder 20 is formed with a disk having a certain thickness at regular intervals in the lower part of the contact surface 22, and the upper surface of the disk is reinforced for strength and easily slips when the vine is rolled up. The stiffener that guides the support shaft 21 to fall may be formed obliquely with a downward slope from the support shaft 21 to the edges in all directions.

That is, the distance between the upper surface of the holder 20 and the lower surface of the first and second vanes 12 and 13 is constant by the inclined surface of the first and second vanes 12 and 13 and the inclined surface of the holder 20. Gaps are formed at regular intervals, and the height of the empty space due to the gaps is about 5 to 10 cm.

And the holder 20 is divided equally to form the first and second holders 20a and 20b with the same vertical symmetry to the left and right about the vertical axis of the center so that the holder 20 is wrapped and fixed on both sides with the branch line G in between. consist of.

In addition, the split surfaces of the first and second holders 20a and 20b, which face each other and are joined, are tightly adhered to each other as if wrapped on both sides with a branch wire G in between, so that the joint position between them is determined when fixed, so that each contact surface Male and female positioning holes 23 and positioning pins 24 are formed so that the (22) forms the same plane.

That is, it can be divided into the first and second holders 20a and 20b and tightly adhered to each other as if wrapped on both sides with the branch line G in between. In this process, the positioning holes 23 formed on each divided surface are formed. and the positioning pins 24 are coupled to each other with an interference fit, so that the assembled state of the first and second holders 20a and 20b can be maintained in a good and stable manner.

In addition, a branch wire fitting groove 29 is formed in the lower center of the dividing surfaces of the first and second holders 20a and 20b facing each other, for inserting and fixing the branch wire G to the outer periphery.

And on both sides of the first and second holders 20a and 20b, tightening portions 25 with through holes 26 are formed to connect them with bolts B and nuts N while in close contact with each other. there is.

In addition, on the dividing surfaces of the tightening portion 25 facing each other, an inclined surface 27 is formed so that the gap gradually widens as it goes outward.

That is, due to the obliquely widened inclined surfaces 27 of the first and second holders 20a and 20b, a gap occurs when the split surfaces facing each other are brought into close contact, and this causes the bolt B to penetrate the through hole 26. When fastened by tightening the nut (N) on the other side, the tightening part (25) is elastically deformed by friction caused by the tightening force of the bolt (B) and nut (N), and the bolt (B) and nut are connected by spring action (repulsion force). By increasing the friction of (N), it is possible to prevent loosening and maintain a firm fixation.

And, among the dividing surfaces of the first and second holders 20a and 20b, a chamfer 28 is provided on the corner portion that meets the contact surface 22 to prevent interference when the lower end of the sleeve 11 rotates. It is formed.

Here, the blade 10 and the holder 20 are preferably made of thermoplastic plastic or synthetic resin, such as Acrylic Styrene Acrylonitrile (ASA), Polyethylene (PE), or Polypropylene (PP).

For example, ASA, which withstands shock well, is easy to process, has excellent weather resistance (a property that resists changes in material properties such as discoloration and cracks due to the external environment) and is unlikely to discolor due to ultraviolet rays or moisture, is injected into a mold and molded or extruded. Uniformity of quality can be achieved by molding as a single piece using a molding method. At this time, unnecessarily thick areas can be lightened and maintain a certain strength through slimming molding.

Meanwhile, in order to prevent the nut (N) from spinning when tightened to the bolt (B), the through hole (26) of the tightening part (25) is formed in a polygon such as a square, and a part of the body of the bolt (B) is preferably formed as a polygon corresponding to the through hole 26.

In addition, the nut (N) is in the form of a flange nut with a washer integrally attached to one side to prevent the nut (N) from loosening or loosening the fixation by tightening by increasing the friction and support force due to fastening with the bolt (B). It is desirable to consist of

<Interaction and operating principle>

The main functions and operating principles of the vine and snake climbing prevention equipment for branch lines according to the embodiment of the present invention configured as described above are explained as follows.

First, as shown in FIG. 10, the blade 10 can be installed to surround the branch line (G) by inserting its sleeve 11 into the outer circumference of the branch line (G), and in this state, when the wind blows, the blade (G) It can freely rotate 360 degrees around the support axis 21 of the holder 20 fixed to.

And the lower ends of the first and second vanes 12 and 13 of the blade 10 have an upward slope from the sleeve 11 toward their respective outer side surfaces, and the first and second vanes 12 The upper surface of the holder 20 facing the lower end of (13) has a downward slope from the support shaft 21 to the edge, thereby separating the first and second vanes 12 and 13 from the holder 20. A gap is formed, and the gap prevents the vines from winding up the blade 10 and naturally shakes and does not become tightly entangled, so the blade 10 can rotate smoothly without being caught in the vines when it turns with the power of the wind. there is.

In addition, the first and second vanes 12 and 13 of the blade 10 are formed in an inverted trapezoidal shape with a width gradually narrowing from the top to the bottom, and the area of the second vane 13 is larger than that of the first vane. It is formed wider than the area of (12), so when the wind is not blowing, the center of gravity of the blade (10) is biased toward the second vane (13) and is always erected toward the ground, so vines or snakes coil up the branch wire from the ground. When trying to go, not only does one not maintain balance, easily slipping down, but also prevents vines or snakes from climbing up the surface of the first and second vanes (12) and (13).

Therefore, it reliably prevents vines or snakes from climbing up the branch line (G) to the electric pole, thereby preventing accidents such as short circuits, electric currents, and power outages from coming into contact with power facilities, including the power lines at the top of the electric pole.

Since the holder 20 is formed by dividing it evenly with the same vertical symmetry to the left and right about the central vertical axis, the worker wraps it from both sides with the branch line G in between and attaches it to the bolt B and the holder 20. The holder 20 can be easily and firmly fixed to the branch wire (G) by turning and tightening the nut (N) by hand.

In this process, the dividing surfaces of the fasteners 25 facing each other are formed as inclined surfaces 27 whose spacing gradually widens as they go outward, so even if the first holder 20a and the second holder 20b are joined in close contact, A gap widening outward occurs between the opposing split surfaces of the fastener 25, and when this happens, the fastener 25 of the holder 20 is pulled inwards due to friction caused by the tightening force of the bolt (B) and nut (N). As it shrinks, it causes elastic deformation, and as a reaction, a repulsive force acts, increasing the friction between the bolt (B) and nut (N), preventing loosening.

In addition, the first and second vanes 12 and 13 are each bent in a curved shape to facilitate the flow of air, thereby minimizing drag and reducing noise when the blade 10 rotates.

In addition, the positioning hole 23 and the positioning pin 24, which are formed to correspond to the dividing surfaces of the first and second holders 20a and 20b, respectively, determine the coupling position between each other to form a contact surface 22. ) not only do not misalign with each other and form a smooth same plane without steps, but also a chamfer 28 is formed on the corner portion that meets the contact surface 22 among the divided surfaces of the first and second holders 20a and 20b, thereby forming a sleeve. Even if the closing portion (11a) is twisted when the lower end of (11) rotates, it does not get caught in the holder (20), so the rotational speed of the blade (10) can be increased, thereby increasing the rotational force caused by the wind.

Therefore, the blade 10 can rotate more smoothly without being caught in a vine.

Meanwhile, as shown in FIG. 11, brims 18 with a circular or hemp-shaped cross-section are provided on the outer side edges of the first and second vanes 12 and 13, respectively, to reinforce the strength and allow the vines to slide down. can be formed.

Here, the brim 18 naturally bends into a curved shape in the process of extrusion molding the first and second vanes 12 and 13 with thermoplastic resin and also serves to induce the formation of a round curve.

Meanwhile, as shown in FIG. 12, the blade 10 may further include a track 14, a pole lock 16, and a ratchet 17.

The tracks 14 are formed to protrude at a certain width on both sides along the longitudinal direction of the sleeve 11.

And vertical grooves 15 are formed on the outer sides of each track 14.

At least one polelock 16 is formed at regular intervals on the inner surface of the vertical groove 15 so that it spreads outward due to the elastic action of the track 14.

That is, the polelocks 16 are arranged in a sawtooth shape when viewed from the top.

The ratchet 17 determines the position within the vertical groove 15 of the track 14 by the biting action of the lock 16 to adjust the installation width of the first and second vanes 12 and 13. It is formed to protrude at regular intervals at the inner ends of the first and second vanes 12 and 13, respectively.

That is, the ratchet 17 is arranged in a sawtooth shape corresponding to the polelock 16 when viewed from the top.

Therefore, the operator can freely adjust the installation width of the first and second vanes (12) and (13) by setting the position of the ratchet (17) with respect to the track (14) according to the installation area or climate. It can be used universally to suit the characteristics of various vines or snakes.

Here, among the components related to the vines for branch lines and the snake climbing prevention device according to other embodiments of the present invention, components having the same or similar effects as the above-described embodiments use the same reference numerals, and repetitive and detailed descriptions thereof are provided.
