Description

Technical Field

[0001] This invention relates to a safety sleeve for corrosion protection of utility poles, and more specifically, to a safety sleeve for corrosion protection of utility poles that can be installed on utility poles to ensure the safety of drivers and pedestrians and to prevent corrosion of the utility poles. Background Technology

[0002] Typically, a utility pole is a vertical support structure erected on the ground for the construction of wiring lines (electric wires or telephone lines) used to provide power or communication services. They are mostly installed in places with high traffic, such as roadsides, and form a cylindrical support made of high-strength materials such as concrete.

[0003] Except in special circumstances, in order to ensure the convenience of construction and maintenance of wiring lines, these utility poles are set up on the roadside and directly exposed to pedestrian traffic or surrounding equipment. In particular, there is always a risk of vehicle collisions at the bends of the road. However, due to the lack of appropriate protection against vehicle collisions, there is a dangerous problem.

[0004] In response, Korean Patent Publication No. 10-2012-0033865 discloses a protective device for a utility pole. In terms of its technology, the structure includes: a support bar, which is provided with a pair of bars that surround and are joined to the utility pole in a mutually symmetrical manner; and a pair of sheaths, which are formed of a mixture of hard and soft materials and surround and are joined to the utility pole in a mutually symmetrical manner on the outside of the support bar.

[0005] Furthermore, in Korean Utility Model Publication No. 20-2009-0007822, which is another prior art, a safety cover is disclosed, the structure of which includes: a buffer part; a cover part surrounding the buffer part; and a reflective part joined to one side of the cover part, and this safety cover is made of a plurality of protective units that are spaced apart by a cutable area and connected to each other.

[0006] However, while the aforementioned prior art mitigates the danger of collisions by being installed on structures including utility poles, it has several problems.

[0007] First, because the cover is pressed tightly against the utility pole, moisture remains inside due to the water curtain effect, thus... Figure 8 As shown in part (a), the concrete pole and its iron core are corroded, causing the pole to become brittle and potentially leading to a major accident due to collapse, posing a serious safety problem.

[0008] Secondly, it takes a long time and considerable effort to set up the strips for securing the cover, especially, as... Figure 8As shown in section (b), the strip connection protrudes in the form of a knot and the ends are sharply exposed to the outside, which often results in pedestrian injuries.

[0009] Third, existing safety covers use paint to coat identification strips. In this case, if exposed to prolonged exposure to external natural environments such as sunlight, rain, and temperature differences, [the following occurs]: Figure 8 As shown in section (c), the exterior, including the luminous display and reflective strip, is prone to fading and corrosion. Maintenance requires significant costs, and local governments with insufficient budgets will be unable to carry out replacement work in a timely manner, which also poses several problems such as negative impacts on the surrounding landscape. Summary of the Invention

[0010] Technical issues

[0011] This invention addresses many problems of the prior art. The purpose of this invention is to provide a safety sleeve for corrosion protection of utility poles, which reduces costs and achieves environmental protection by maximizing the recycling rate of waste plastics, and prevents corrosion and breakage of utility poles caused by moisture by forming a non-contact airflow path between the safety sleeve and the utility pole.

[0012] Furthermore, the present invention aims to provide a safety sleeve for corrosion protection of utility poles, wherein an identification strip of a specified thickness is formed by using colored plastic and a double extrusion process to prevent discoloration, and the sleeve can be installed on the utility pole in a knotless manner by means of a fastening strip engaging with a hook plate and a hook hole.

[0013] Technical solution

[0014] As a specific solution for achieving the above-mentioned objectives, the safety sleeve for corrosion protection of utility poles of the present invention is characterized by comprising: a base plate portion 10, formed as a sinusoidal curved surface 12, the curved surface 12 having an inwardly curved portion 12a and an outwardly curved portion 12b that alternately and repeatedly bend on its inner circumferential surface; an identification strip portion 20, on the outer surface of the base plate portion 10, formed by alternating and repeating different kinds of colors; a side plate portion 30, formed at both ends of the base plate portion 10, having hook holes 32; and a fastening strip 40, provided with a plurality of hook pieces 42 for insertion and engagement with the hook holes 32 of the side plate portion 30, wherein the base plate portion 10 is configured such that, when the inwardly curved portion 12a is partially grounded to the outer circumferential surface of the utility pole, the outwardly curved portion 12b is separated from the outer circumferential surface of the utility pole 1 to form a non-contact airflow path 12c.

[0015] In this case, the feature of the present invention is that the identification strip 20 is formed by extruding colored plastic in a manner that overlaps with the surface of the base plate 10. The recycled plastic forming the base plate 10 and the colored plastic constituting the identification strip 20 have different melting points. While the base plate 10 is extruded with a predetermined cross-sectional shape by the main extruder, the identification strip 20 is extruded with a thickness relatively thin compared to the base plate 10 by the auxiliary extruder.

[0016] Furthermore, the present invention is characterized in that a plurality of particles 50, which expand or explode due to heat above a predetermined temperature, are distributed on the joint surface of the base plate portion 10 and the identification strip portion 20. During the extrusion molding process, the particles 50 are heated to expand or explode, thereby physically bonding the surfaces of the base plate portion 10 and the identification strip portion 20.

[0017] Furthermore, the present invention is characterized in that an inner concave-convex line 14 is formed on the surface of the base plate portion 10, an identification band portion 20 of uniform thickness is formed on the surface of the inner concave-convex line 14, and an outer concave-convex line 24 with the same pattern as the inner concave-convex line 14 is formed on the identification band portion 20.

[0018] Furthermore, the present invention is characterized in that the side plate portion 30 has a recessed arc-shaped guide surface 34 on its inner peripheral surface, and the guide surface 34 is guided in such a way that it bends toward the pole 1 and moves the fastening strip 40 introduced through the hook hole 32.

[0019] Furthermore, the present invention is characterized in that the tension of the fastening strip 40 is adjusted by the engagement tool 46, which includes: an engagement plate 46a supported by the outer peripheral surface of the fastening strip 40; a pair of forks 46b, one end of which is connected to the engagement plate 46a and the other end of which extends to the inner peripheral surface of the fastening strip 40 and engages with the locking hook 42; and a handle 46c connected to the engagement plate 46a.

[0020] Furthermore, the present invention is characterized in that the fastening strip 40 is divided into two parts, one end of which is inserted into the hook hole 32 of the side plate 30, and the other end forms an overlapping part 44 that overlaps with each other and is engaged by the clamp 45. The overlapping part 44 forms a locking protrusion 44a on the corresponding surfaces, and is engaged by the engraved and embossed structure.

[0021] The effects of the invention

[0022] According to the embodiments used to achieve the above objectives, the present invention can reduce costs and achieve environmental protection by maximizing the recycling rate of waste plastics.

[0023] In particular, the corrosion and breakage of utility poles caused by moisture can be prevented by creating a non-contact airflow path between the safety sheath and the pole.

[0024] Furthermore, because the identification strip with a specified thickness is formed by using colored plastic and double extrusion molding, it will not suffer from poor visibility due to wear and has excellent weather resistance, thus maintaining clear visibility for a long time.

[0025] In particular, since the fastening strip is set in a knotless manner by means of the locking combination of hook plate and hook hole, it is difficult to untie the connection except by management personnel. This can prevent safety accidents such as pedestrians being injured by knots during movement, and has many expected benefits. Attached Figure Description

[0034] The technical terms used in this specification are selected with consideration for the functionality of the embodiments described herein, and their meanings may vary depending on the specific embodiment of the invention. Furthermore, throughout the specification, when referring to a part as being "connected" to other parts, this includes not only "direct connection" but also "indirect connection" with other components in between. Additionally, the terms "upper side," "lower side," and "front-back direction," etc., used in the following description are defined based on the accompanying drawings, and the shape and position of the various structural elements are not limited by these terms.

[0035] The present invention will now be described in more detail with reference to specific embodiments shown in the accompanying drawings. Figure 1The figure illustrates a preferred embodiment of the safety sleeve for corrosion protection of utility poles provided by the present invention. Figure 2 This is a top view showing the state in which a safety sleeve for corrosion protection is installed on the utility pole.

[0036] This invention relates to a safety sleeve for corrosion protection of utility poles, which reduces costs and achieves environmental protection by maximizing the recycling rate of waste plastics. It prevents corrosion and breakage of utility poles caused by moisture by forming a non-contact airflow path between the safety sleeve and the utility pole. The main structure is roughly divided into a base plate 10, an identification strip 20, a side plate 30, and a fastening strip 40.

[0037] First, the base plate portion 10 of the present invention is extruded in a manner having a specified cross-sectional shape, and can be cut to a specified length for use, taking into account the length of the utility pole and the environment of the installation location.

[0038] The aforementioned base plate portion 10 is formed as a sinusoidal curved surface 12, which has an alternating inward bending portion 12a and an outward bending portion 12b on its inner circumferential surface. Therefore, as Figure 2 As shown in the enlarged view, when it is set up in a manner that surrounds the utility pole 1, a non-contact airflow path 12c will be formed through the sinusoidal curved surface 12.

[0039] In this case, in order to achieve smooth drainage, a sinusoidal wave surface 12 with a height of 0.2 mm or more is formed on the flat cross-section of the aforementioned non-contact airflow path 12c.

[0040] With the structure described above, the base plate 10 is configured such that when the inwardly bent portion 12a is partially grounded to the outer periphery of the utility pole, a non-contact airflow path 12c is formed between the outwardly bent portion 12b and the outer periphery of the utility pole 1, separated by more than 0.2 mm. In this way, rainwater can be quickly discharged through the non-contact airflow path 12c in rainy weather, and at the same time, convenient air circulation keeps the base plate 10 and the utility pole 1 in a dry state, thereby preventing corrosion and breakage of the utility pole 1 caused by moisture.

[0041] The aforementioned base plate portion 10 is formed by extruding recycled plastic, and the identification strip portion 20 is formed by extruding colored plastic in a manner that overlaps with the surface of the base plate portion 10.

[0042] The identification strip 20 of the present invention is formed alternately and repeatedly on the surface of the base plate 10 with different kinds of colors so that the driver can easily identify it.

[0043] As an example, such as Figure 1As shown, the identification strip 20 is formed in a state of alternating gray and black areas. In this case, the width of the gray area is smaller than that of the black area (for example, 70-80 mm for the black area and 40-60 mm for the gray area). A hazard warning statement is screen-printed in the gray area at the very center, and reflective paper is attached to the adjacent gray area to improve the driver's visibility during daytime and nighttime driving.

[0044] On the other hand, while the base plate portion 10 is extruded with a specified cross-sectional shape by the main extruder, the identification belt portion 20 is extruded with a thickness relatively thin compared to the base plate portion 10 by the auxiliary extruder, thereby manufacturing the safety sleeve in a multi-extrusion manner.

[0045] In this case, the recycled plastic forming the base plate portion 10 and the colored plastic constituting the identification strip portion 20 have different melting points, and among the colored plastics, the melting points of the plastics in the gray and black areas are also different. As an example, the melting point of the colored plastic can be set to be lower.

[0046] If the above resins have the same melting point, the boundary between the gray area and the black area may not be obvious, or the thickness of the identification strip 20 layered on the base plate 10 may be uneven.

[0047] Figure 3 To illustrate the structural diagram of the joint state of the base plate portion and the identification strip portion of the safety sleeve for anti-corrosion of utility poles according to an embodiment of the present invention, a plurality of particles 50 that expand or explode due to heat above a predetermined temperature are distributed on the joint surface of the base plate portion 10 and the identification strip portion 20.

[0048] During the extrusion molding of the base plate portion 10 and the identification belt portion 20, the surfaces of the base plate portion 10 and the identification belt portion 20 are physically bonded by heating and causing the particles 50 to explode, thereby firmly maintaining the integrity of the dual extrusions between different materials.

[0049] In this way, while the identification strip 20 is double-extruded onto the base plate 10, it is formed from colored plastic (PVC) to a specified thickness (0.2–0.4 mm), thus avoiding poor visibility due to wear. Furthermore, even after prolonged exposure to external natural environments such as sunlight, snow, rain, and temperature differences, it exhibits excellent weather resistance without discoloration or fading, providing the advantage of consistently ensuring clear visibility for safe driving. Moreover, since the base plate 10 is formed from recycled plastic (waste plastic), manufacturing costs can be reduced through resource recycling. Furthermore, waste recycling contributes to carbon neutrality policies, resulting in environmental benefits.

[0050] Figure 4To show a magnified view of the identification band of the safety sleeve used for corrosion protection of utility poles, Figure 4 Part a is a structural diagram showing the black area of ​​the identification band 20. Figure 4 Part (b) is a structural diagram showing the gray area of ​​the identification band 20.

[0051] An inner raised line 14 is formed on the surface of the base plate portion 10, and an identification strip portion 20 is formed on the surface of the inner raised line 14. In this case, as the identification strip portion 20 is formed with a uniform thickness, an outer raised line 24 will be formed on the surface of the identification strip portion 20.

[0052] That is, during the extrusion of the base plate portion 10, an inner concave-convex line 14 is formed on the surface by an extruder die, and then an identification strip portion 20 is extruded on the surface of the inner concave-convex line 14, thereby forming an outer concave-convex line 24 with the same shape and pattern as the inner concave-convex line 14.

[0053] With the inner concave-convex lines 14 and outer concave-convex lines 24 of this structure, when the base plate 10 is surrounded and set on the utility pole 1, the flexibility of the shape transformation into a circle will be improved. At the same time, the surface adhesion area of ​​illegal stickers, including leaflets, will be reduced, thus having the advantage of being easy to remove.

[0054] Figure 5 This is a structural diagram illustrating the fastening strip connection structure of a safety sleeve for corrosion protection of utility poles according to an embodiment of the present invention.

[0055] The side plate portion 30 of the present invention is formed at both ends of the bottom plate portion 10, and hook holes 32 are formed thereon. The identification strip portion 20 having a specified color can be formed on the outer peripheral surface of the side plate portion 30 by double injection molding.

[0056] like Figure 5 As shown, in plan view, the side plate portion 30 has a recessed arc-shaped guide surface 34 on its inner circumferential surface, and its outer surface is also integrally curved in a way that minimizes the amount of external impact. The guide surface 34 is guided in such a way that it bends toward the pole 1 and moves the end of the fastening strip 40 introduced through the hook hole 32.

[0057] Therefore, the fastening strip 40 bends inward along the guide surface 34 of the side plate portion 30 and is quickly inserted without jamming. This guidance makes the fastening operation effective and ensures that the fastening strip 40 is tightly attached to the inside of the hook hole 32, thereby firmly maintaining the bonding force between the hook plate 42 and the hook hole 32.

[0058] The fastening strip 40 of the present invention is made of a flexible and elastic synthetic resin material, and a plurality of hook pieces 42 are formed protruding obliquely on one side in such a way as to be inserted into and combined with the hook hole 32 of the side plate portion 30.

[0059] like Figure 1 As shown, the hook pieces 42 are formed in opposite directions on both sides of the fastening strip 40. That is, the hook pieces 42 disposed at the two ends of the fastening strip 40 form an acute angle with the fastening strip, so that with one side of the hook piece 42 fastened to the hook hole 32 of the side plate portion 30, the other side of the fastening strip 40 is inserted into the hook hole 32 of the opposite side plate portion 30 and fastened.

[0060] In this way, the aforementioned fastening strip 40 can securely attach the safety sleeve to the utility pole in a knotless manner by means of the locking engagement of the hook plate 42 and the hook hole 32. Since the fastening part is not exposed to the outside, the engagement cannot be released except by the administrator.

[0061] Furthermore, it has the following advantages: it can prevent the occurrence of safety accidents caused by the metal knot protruding outwards, which would obstruct the appearance and lead to pedestrian injuries during movement.

[0062] Figure 6 The diagram illustrates the structure of the tool for attaching the safety sleeve, used to easily adjust the tension of the fastening strip 40 so that the safety sleeve is securely fastened to the utility pole.

[0063] Specifically, the aforementioned engagement tool 46 includes: an engagement plate 46a, supported by the outer peripheral surface of the fastening strip 40; a pair of forks 46b, one end of which is connected to the engagement plate 46a and the other end extends to the inner peripheral surface of the fastening strip 40 and is engaged with the hook 42; and a handle 46c, which is connected to the engagement plate 46a.

[0064] The handle 46c is not positioned on the same straight line as the connecting plate 46a, but rather forms an intersection to increase the force required to pull the fastening strip 40 during use.

[0065] Observe the usage state, with the fastening strip 40 inserted between the connecting plate 46a and the fork 46b, so that the hook 42 is engaged with the fork 46b. If the handle 46c is pulled outward along the direction of the arrow shown, the fastening strip 40 can be easily pulled by lever and easily entered into the hook hole 32. Therefore, the safety sleeve can be securely fastened to the utility pole.

[0066] Figure 7 This is a structural diagram illustrating an embodiment of the fastening strip clamp for the safety sleeve for corrosion protection of utility poles according to the present invention.

[0067] In this case, the fastening strip 40 is divided into two parts, one end of which is inserted into the hook hole 32 of the side plate 30, and the other end forms an overlapping part 44 that overlaps with each other and is joined by the clamp 45.

[0068] Furthermore, locking protrusions 44a are formed on the corresponding surfaces of the overlapping portions 44, and the engagement is achieved through the interlocking of the engraved and embossed structures.

[0069] In this case, the aforementioned clamp 45 has a through hole that can accommodate all the overlapping portions 44, and a tightening bolt is provided on one side for threaded fastening. By tightening the tightening bolt while the overlapping portions 44 are inserted into the clamp 45, the overlapping portions 44 are brought into close contact and the locking protrusions 44a are engaged with each other, thereby maintaining a firm engagement state.

[0070] As described above, the most preferred embodiments of the present invention have been presented in the detailed description of the invention, but various modifications can be made without departing from the scope of the invention. Therefore, the scope of protection of the present invention is not limited to the above embodiments, and the techniques and equivalent technical solutions within the scope of the appended claims should also be considered to fall within the scope of protection.

[0071] Industrial availability

[0072] The safety sleeve provided by this invention can prevent pole corrosion and breakage caused by moisture by forming a non-contact airflow path between the safety sleeve and the pole. It provides excellent weather resistance and visibility, and therefore has very high industrial applicability.
