Description

Vine and snake climbing prevention devices for branch lines

[0001] The present invention relates to a vine and snake climbing prevention device for a ground line that prevents vines or snakes from climbing up by winding around a ground line that reinforces a pole on the ground, and more specifically, to a vine and snake climbing prevention device for a ground line that allows vines or snakes to easily slide down when they try to climb up by winding around a ground line, and also increases rotational force due to wind so that they rotate smoothly without getting caught in tangled vines, and further allows for simple and sturdy installation on a ground line.

[0002] In general, a guy wire (wire ropes supporting electric pole) is a support line that is erected diagonally above the ground to prevent the pole from being toppled by the tension of the electric wire or the wind. In particular, in the case of a common guy wire, one end is connected to the end of the electric line or the top of the pole using a guy band, and the other end is fixed to a stay block buried in the ground using a stay rod. The installation angle with the pole is usually formed at 30 to 45 degrees.

[0003] Meanwhile, there is a problem that accidents such as short circuits, leakage of electricity, and power outages frequently occur when vines climb up poles supporting overhead distribution lines while wrapping around branch lines, or when snakes climb up poles while wrapping around branch lines using the lateral undulating motion of their scales across their abdomens to catch and eat eggs or young in their nests on poles, as they come into contact with high-voltage power lines and other power facilities.

[0004] In relation to this, a conventional technology, patent document 1, discloses a snake and vine climbing prevention device for a utility pole branch line that can prevent vines or snakes from climbing up the utility pole by wrapping themselves around the branch line.

[0005] That is, as illustrated in Fig. 1, 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).

[0006] However, this has a problem in that the vines are tightly wrapped around the first and second wing parts (120) (130) and the lower fixed part (150), and when this happens, the first wing part (120) and the second wing part (130) are caught in the vines and cannot rotate, so the vines easily wrap around the first wing part (120) and the second wing part (130).

[0007] To solve this problem, a vine climbing prevention device for preventing vine entanglement was disclosed in Patent Document 2.

[0008] That is, as shown in FIG. 2, Patent Document 2 forms a space (gap) between the first and second wing parts (120) (130) that can rotate around the branch line (20) and the fixing part (140) that is fixed to the branch line (20) to support them, so that the vines do not naturally sway or slide down and wrap around the first and second wing parts (120) (130), and as a result, the vines do not wrap tightly around the first and second wing parts (120) (130), so that the first and second wing parts (120) (130) can rotate smoothly without being obstructed by the vines when the wind blows.

[0009] However, since this is a structure that rotates when the wind hits the first and second wings (120)(130), there is a limitation that the rotational force is considerably reduced.

[0010] In addition, there is a problem that it is very difficult to firmly install the fixed part (150) on the branch line (20) due to its structural characteristics of maintaining its fixed state by simply creating friction with the branch line (20) through the tightening force of the bolt and nut.

[0011] Furthermore, there is a problem that the fixed parts (150) are misaligned and fixed in steps during the process of being installed on the branch line, and as a result, the lower part of the branch line installation part (110) that comes into contact with the fixed part (150) gets caught on the protrusion of the fixed part (150) when rotating, preventing it from rotating smoothly.

[0012] That is, the branch installation part (110) has a morphological characteristic in that it is cut so that one side can be opened for installation by fitting it into the outer circumference of the branch line (G), and there is a branch insertion part (112) for blocking the gap of the cut part. When the branch installation part (110) is rotated by the wind, the branch insertion part (112) twists and gets caught on the protrusion of the fixing part (150), causing contact interference, which not only significantly reduces the rotational force, but in severe cases, causes deformation and breakage.

[0013] The background technology or prior art described herein is information that the inventor possesses or acquired in the process of deriving and completing the present invention, and is helpful in understanding the technical significance of the present invention and is useful in prior art research and examination, and is stated hereinabove. In addition, the drawing symbols in the prior art are not related to the drawing symbols in the present invention.

[0014] Accordingly, the inventor of the present invention has comprehensively considered all the above-mentioned matters and, at the same time, has made great efforts to develop a novel vine and snake climbing prevention device for branch lines, which not only allows vines or snakes to slide down easily and naturally when they try to climb up, but also prevents them from climbing up the overhead distribution lines while wrapping around the branch lines on the ground, up around the poles, and around the steel bars supporting the overhead distribution lines, but also increases the rotational force caused by the wind, so that they rotate smoothly without getting caught on vines, and can be installed simply and sturdily on branch lines, and furthermore, can be used universally by adjusting the width to suit various vines or snakes of different sizes depending on the characteristics of the region or climate, and as a result, has continuously researched and made every effort to create the present invention.

[0015] Therefore, the technical problem and purpose to be solved by the present invention is to provide a vine and snake climbing prevention device for a branch line that allows vines and snakes to easily slide down and increase rotational force due to wind.

[0016] Another technical problem and object of the present invention is to provide a vine and snake climbing prevention device for a branch line that can be easily and sturdily installed on the branch line.

[0017] Another technical problem and object of the present invention is to provide a vine and snake climbing prevention device for a branch line that can be universally used by adjusting the width according to the characteristics of various regions or climates.

[0018] 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 will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0019] In order to effectively achieve a specific technical purpose while embodying a new idea for solving the technical problem of the present invention as described above, a specific means according to an embodiment of the present invention is proposed, which comprises a long cylindrical sleeve formed on the outer periphery of the branch line so as to surround the branch line at the center thereof, first and second vanes protruding from both sides along the longitudinal direction of the sleeve to cause vines or snakes to slide down when they try to climb up and to rotate around the branch line with the force of the wind, a blade formed by protruding from the outer periphery of the branch line, a support shaft formed at the upper center thereof and fitted into the lower hole of the sleeve, a contact surface formed at the lower portion of the support shaft that contacts the sleeve to support the blade so as to be rotatable, and a gap formed to separate the first and second vanes of the blade from the holder.

[0020] Accordingly, the present invention can achieve the effect of preventing vines or snakes from climbing up the overhead power line by easily and naturally sliding down the power pole and reaching the surrounding steel bars supporting the overhead power line.

[0021] In addition, as a preferred embodiment (aspect) of the present invention, the lower ends of the first and second vanes have an upward slope in the outer side direction of each of them from the sleeve, and the upper surface of the holder facing the lower ends of the first and second vanes has a downward slope in the edge direction from the support shaft, so that the vines do not get wrapped around and naturally shake, and do not get tangled tightly, so that the vines can rotate smoothly without getting caught on the vines when the wind blows.

[0022] In addition, as a preferred embodiment (aspect) of the present invention, the holder is formed by first and second holders that are equally divided to the left and right with the same vertical symmetry based on the vertical axis of the center so as to be wrapped and fixed from both sides with the branch line in between, and a male and female positioning hole and a positioning pin are respectively formed on the divided surfaces facing each other of the first and second holders so as to determine the mutual coupling position when fixing by wrapping and closely contacting from both sides with the branch line in between, so that the contact surfaces form the same plane, and a fastening part having a through hole is respectively formed on both sides of the first and second holders, and an inclined surface that is gradually inclined with the gap widening toward the outside is formed on the divided surfaces facing each other of the fastening part, so that when a bolt is driven through the through hole and a nut is tightened from the opposite side, the fastening part is elastically deformed by the frictional force due to the tightening force of the bolt and the nut, and the frictional force of the bolt and the nut increases by the spring action to prevent loosening, and thus the installation on the branch line can be more simply and firmly performed. there is.

[0023] In addition, a preferred embodiment (aspect) of the present invention is that a brim is formed on the outer side edge of the first and second vanes to reinforce strength while allowing vines to slide down, and the first and second vanes are formed in an inverted trapezoidal shape whose width gradually narrows from the top to the bottom, and the width of the second vane is formed wider than that of the first vane, so that when there is no wind, the second vane, where the center of gravity of the blade is located, turns toward the ground around the ground line and stands up toward the pole, thereby preventing vines or snakes from winding up or climbing up the surfaces of the first and second vanes.

[0024] In addition, a preferred embodiment (aspect) of the present invention is that the first and second vanes are each curved, and a chamfer is formed at the corner portion of the dividing surface of the first and second holders where the contact surface meets the edge portion so that the lower end of the sleeve does not get caught when rotating, thereby increasing the rotational speed of the blade and increasing the rotational force due to the wind, so that the blade can rotate more smoothly without getting caught on the vine.

[0025] In addition, a preferred embodiment (aspect) of the present invention further comprises a track formed by protruding at a constant width on both sides along the longitudinal direction of the sleeve, a pole formed at a constant interval on each inner surface of the vertical groove and spread outward by the elastic action of the track, and a ratchet formed by protruding at a constant interval on each inner end of the first and second vanes and determining the position within the vertical groove of the track by the biting action of the pole to adjust the installation width of the first and second vanes, thereby freely adjusting the installation width of the first and second vanes, so that the width can be adjusted to suit the characteristics of vines or snakes of different sizes depending on the region or climate, and can be used universally.

[0026] According to an embodiment that implements the technical idea on which the unique solution is based in order 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 when a vine or snake tries to climb up the ground wire, it easily slides down, and in particular, the vine does not climb up but naturally shakes and does not become entangled, so that the blade can rotate smoothly without getting caught on the vine when it turns by the force of the wind.

[0027] Therefore, it is possible to prevent vines or snakes from climbing up the branch line to the electric pole, thereby preventing accidents such as short circuits, leakage, and power outages from occurring when they come into contact with power equipment, including power lines, on top of the pole.

[0028] In addition, the worker can easily and firmly fix the holder to the branch line by turning the bolt and nut by hand to tighten it, and in this process, the tightening part of the holder is elastically deformed due to the frictional force from the tightening force of the bolt and nut, and the frictional force of the bolt and nut is increased by the spring action (repulsive force), thereby preventing loosening.

[0029] Moreover, the first and second vanes are each curved, and the facing dividing surfaces of the first and second holders are formed with male and female positioning holes and positioning pins that determine the mutual joining positions so that the contact surfaces do not misalign and form a smooth, flat plane, and in addition, a chamfer is formed at the corner portion of the dividing surfaces of the first and second holders where the contact surfaces meet, thereby ensuring smooth airflow and increasing the rotational force of the blade by preventing the lower end of the sleeve from getting caught in the holder when rotating, thereby allowing the blade to rotate more smoothly without getting caught in the vines.

[0030] In addition, the operator can freely adjust the installation width of the first and second vanes according to the installation area or climate, so it can be used universally to suit the characteristics of various vines or snakes.

[0031] In other words, it can be used universally by adjusting the width to suit the characteristics of vines or snakes that vary in size depending on the region or climate, so it maximizes convenience and efficiency of use as well as functionality and usability, and accordingly, it can promote convenience in use such as enhancing marketability through economic feasibility and product differentiation.

[0053] <Specific implementation form>

[0054] The main elements constituting the vine and snake climbing prevention device for the branch line according to the embodiment of the present invention largely include a blade (10) and a holder (20) as shown in FIGS. 3 to 10.

[0055] The blade (10) is fixed to the ground wire (G) by a holder (20), and a long cylindrical sleeve (11) is formed in the center thereof to surround the ground wire (G) and fit around the outer periphery of the ground wire (G).

[0056] And, on both sides along the length of the sleeve (11), first and second vanes (12) (13) are formed protruding to cause vines or snakes to slide down when they try to climb up, and to rotate with the force of the wind around the branch line (G).

[0057] Additionally, a gap is formed between the first and second vanes (12)(13) and the holder (20) at a constant interval.

[0058] In addition, the lower ends of the first and second vanes (12) (13) are formed obliquely with an upward slope in the outer side direction from the sleeve (11) to prevent the vines from winding up.

[0059] And the first and second vanes (12)(13) are formed in a trapezoidal shape with the width gradually narrowing from the top to the bottom.

[0060] Additionally, the width of the second vane (13) is formed wider than the width of the first vane (12).

[0061] That is, the first vane (12) and the second vane (13) are formed asymmetrically with the upper and lower portions having different shapes centered on the sleeve (11).

[0062] And the first and second vanes (12)(13) are each curved to increase the rotational speed of the blade (10).

[0063] In addition, the outer upper and lower corners of the first and second vanes (12)(13) are rounded.

[0064] In addition, in order to forcibly spread one side of the sleeve (11) and fit it to the branch line (G), the side of the sleeve (11) that comes into contact with the second vane (13) is cut along its length, and a closing portion (11a) is formed in the cut portion to prevent a gap by maintaining a state of close contact with the inner edge of the second vane (13).

[0065] Here, the thickness of the first and second vanes (12)(13) is preferably formed to be approximately 0.5 mm to 5 mm to ensure flexibility and hardness that does not break easily, and the length is preferably formed to be approximately 0.5 m to 3 m to minimize the influence of the type of vine and the size of the snake.

[0066] In addition, it is preferable that the lower slopes of the first and second vanes (12)(13) be formed at about 20 to 60 degrees.

[0067] Additionally, the first and second vanes (12)(13) may be surface-processed separately to maximize the appearance (discoloration prevention) and the slipping effect of vines and snakes.

[0068] The holder (20) is formed in a hollow shape and is fixed by fitting it to the outer circumference of the support line (G) to support the blade (10) so that it can rotate freely 360 degrees. A vertically long cylindrical support shaft (21) is formed by protruding from the upper center portion thereof to fit into the lower hole of the sleeve (11).

[0069] And, on the outer circumference of the support shaft (21), a plurality of ring bearings (21a) are formed at regular intervals to reduce friction by point contact when the blade (10) rotates.

[0070] In addition, a contact surface (22) that comes into contact with the sleeve (11) is formed protruding around the lower circumference of the support shaft (21).

[0071] Additionally, the holder (20) is formed with a slope that is inclined downward from the contact surface (22) so that the vine can easily slide down when it tries to climb up.

[0072] For example, the holder (20) can be formed in a shape and form in which a support shaft (21) is integrally formed on the upper surface of a hollow tube in the shape of a cone-shaped cylinder.

[0073] In addition, the holder (20) may be formed with a disc having a certain thickness at a certain interval on the lower part of the contact surface (22) to make it difficult for the vine to wind up, and a stiffener may be formed on the upper surface of the disc at an angle with a downward slope from the support shaft (21) toward the four edges to reinforce the strength and induce the vine to slide down easily when winding up.

[0074] That is, a gap is formed between the upper surface of the holder (20) and the lower surfaces of the first and second vanes (12) (13) at a constant interval by the inclined surfaces of the first and second vanes (12) (13) and the inclined surface of the holder (20), and the height of the empty space due to the gap is formed to be approximately 5 to 10 cm.

[0075] And the holder (20) is composed of first and second holders (20a) (20b) that are evenly divided to form the same vertical symmetry to the left and right based on the vertical axis of the center so as to be wrapped and fixed on both sides with the branch line (G) in between.

[0076] In addition, the first and second holders (20a) (20b) are formed with a male and female positioning hole (23) and a positioning pin (24) that are formed on the facing and combined surfaces of the first and second holders (20a) (20b) so that the position of the joints is determined by wrapping and fixing them from both sides with a ground line (G) in between, so that the respective contact surfaces (22) form the same plane.

[0077] That is, it can be divided into first and second holders (20a) (20b) and tightly closed from both sides with a branch line (G) in between, and in this process, the positioning holes (23) and positioning pins (24) formed on each of the divided surfaces are forcibly fitted together, thereby maintaining the assembly state of the first and second holders (20a) (20b) in a good and stable manner.

[0078] In addition, a wire insertion groove (29) is formed in the lower center of the facing dividing surfaces of the first and second holders (20a) (20b) to fit and fix the wire (G) to the outer periphery.

[0079] And, on both sides of the first and second holders (20a) (20b), a fastening part (25) having a through hole (26) is formed so as to be joined with a bolt (B) and a nut (N) while in close contact with each other.

[0080] In addition, the facing dividing surfaces of the joint (25) are formed with an inclined surface (27) that gradually becomes wider as it goes outward.

[0081] That is, due to the slanted inclined surfaces (27) of the first and second holders (20a) (20b), a gap is created when the facing dividing surfaces are pressed against each other, and when a bolt (B) is inserted into the through hole (26) and a nut (N) is tightened from the opposite side to fasten it, the tightening force of the bolt (B) and the nut (N) causes the tightening portion (25) to be elastically deformed due to the frictional force, and the spring action (repulsive force) increases the frictional force between the bolt (B) and the nut (N), thereby preventing loosening and maintaining a solid fixed state.

[0082] And, at the corner portion where the contact surface (22) meets the facing dividing surface of the first and second holders (20a) (20b), a chamfer (28) is formed to prevent interference from occurring when the lower end of the sleeve (11) rotates.

[0083] Here, the blade (10) and holder (20) are preferably formed of a thermoplastic plastic or synthetic resin such as ASA (Acrylic Styrene Acrylonitrile), PE (Polyethylene), PP (Polypropylene), etc.

[0084] For example, ASA, which is shock-resistant, easy to process, and has excellent weather resistance (the property of withstanding changes in material properties such as discoloration and cracking due to external environments), is not easily discolored by ultraviolet rays or moisture, can be molded by injection into a mold or formed integrally using extrusion molding to ensure uniform quality. In this case, unnecessarily thick areas can be reduced in weight and maintain consistent strength through thinning molding.

[0085] Meanwhile, in order to prevent loosening when tightening the nut (N) on the bolt (B), it is preferable that the through hole (26) of the tightening portion (25) be formed into a polygon such as a square, and that a part of the body of the bolt (B) be formed into a polygon corresponding to the through hole (26).

[0086] In addition, it is preferable that the nut (N) be in the form of a flange nut with a washer integrally attached to one side to increase friction and support force when fastened with the bolt (B) and prevent the fastening state from becoming loose or relaxed due to tightening.

[0087] <Interaction and Operation Principle>

[0088] The main functions and operating principles of the vine and snake climbing prevention device for branch lines according to the embodiment of the present invention configured as described above are described as follows.

[0089] First, as shown in Fig. 10, the blade (10) can be installed to surround the branch line (G) by fitting its sleeve (11) to the outer periphery of the branch line (G), and in this state, when the wind blows, it can freely rotate 360 ​​degrees around the support axis (21) of the holder (20) fixed to the branch line (G).

[0090] And the lower ends of the first and second vanes (12) (13) of the blade (10) have an upward slope in the outer side direction from the sleeve (11), and also, the upper surface of the holder (20) facing the lower ends of the first and second vanes (12) (13) has a downward slope in the edge direction from the support shaft (21), thereby forming a gap that separates the first and second vanes (12) (13) and the holder (20), and because the vines do not wrap around the blade (10) due to the gap and naturally shake without becoming tangled, the blade (10) can rotate smoothly without getting caught on the vines when it rotates by the force of the wind.

[0091] In addition, the first and second vanes (12)(13) of the blade (10) are formed in an inverted trapezoidal shape that gradually narrows from the top to the bottom, and the width of the second vane (13) is formed wider than that of the first vane (12), so that when there is no wind, the center of gravity of the blade (10) is biased toward the second vane (13) and is always erected toward the ground, so that when a vine or snake tries to climb up the ground line, it is not only difficult to maintain balance and easily slip down, but also prevents the vine or snake from climbing up the surface of the first and second vanes (12)(13).

[0092] Therefore, it is possible to prevent vines or snakes from climbing up the branch line (G) to the electric pole, thereby preventing accidents such as short circuits, leakage, and power outages from occurring when they come into contact with power equipment, including power lines, on top of the pole.

[0093] And since the holder (20) is formed by dividing it evenly to the left and right with the same vertical symmetry based on the vertical axis of its center, the worker can easily and firmly fix the holder (20) to the ground wire (G) by wrapping it on both sides with the ground wire (G) in between and then tightening the bolt (B) and nut (N) by hand.

[0094] In this process, since the facing dividing surfaces of the tightening portion (25) are formed as inclined surfaces (27) whose gaps gradually widen as they go outward, even if the first holder (20a) and the second holder (20b) are tightly coupled, an outward gap is generated between the facing dividing surfaces of the tightening portion (25), and in this case, the tightening portion (25) of the holder (20) contracts inward due to the frictional force caused by the tightening force of the bolt (B) and the nut (N), causing elastic deformation, and as a reaction, a repulsive force acts to increase the frictional force of the bolt (B) and the nut (N), thereby preventing loosening.

[0095] In addition, the first and second vanes (12)(13) are each curved to facilitate the flow of air, thereby minimizing drag and reducing noise when the blade (10) rotates.

[0096] And the positioning holes (23) and positioning pins (24) formed to correspond to the facing dividing surfaces of the first and second holders (20a) (20b) respectively determine the mutual joining positions so that the contact surfaces (22) do not misalign with each other and form a smooth, flat plane without any steps. In addition, a chamfer (28) is formed at each corner portion of the dividing surfaces of the first and second holders (20a) (20b) where the contact surface (22) meets, so that even if the closing portion (11a) is twisted when the lower end of the sleeve (11) rotates, it does not get caught by the holder (20), thereby increasing the rotational speed of the blade (10) and increasing the rotational force caused by the wind.

[0097] Therefore, the blade (10) can rotate more smoothly without getting caught on the vine.

[0098] Meanwhile, as shown in Fig. 11, a brim (18) having a circular or horse-shaped cross-section that reinforces strength and allows the vine to slide down may be further formed on the outer side edges of the first and second vanes (12) (13).

[0099] Here, the brim (18) also plays a role in inducing the first and second vanes (12)(13) to naturally bend into a curved shape and form a round curve during the process of extrusion molding with thermoplastic resin.

[0100] Meanwhile, as shown in FIG. 12, the vine and snake climbing prevention device for a branch line according to another embodiment of the present invention may be configured such that the blade (10) further includes a track (14), a pole lock (16), and a ratchet (17).

[0101] The track (14) is formed by protruding with a constant width on both sides along the length of the sleeve (11).

[0102] And each of the outer sides of the track (14) has a vertical groove (15) formed.
