Description

The present invention relates to a safety guard for preventing corrosion of utility poles, and more specifically, to a safety guard for preventing corrosion of utility poles that is installed on utility poles to ensure the safety of drivers and pedestrians as well as to prevent corrosion of the utility poles.

Utility poles are usually erected above ground to install electrical wiring or telephone lines to provide electricity and communication services. In most cases, they are installed in areas with high traffic such as roadsides, and are made as cylindrical supports made of high-strength materials such as concrete.

Except in special cases, such utility poles are installed near roads and are exposed to people and surrounding equipment in order to make wiring and maintenance work easier. There is a problem that, although there is always a risk of vehicle collisions at bends in the road, there is no significant protection against vehicle collisions, making them dangerous.

For this reason, the previously disclosed Korean Patent Publication No. 10-2012-0033865 previously disclosed a technology for a protection device for protecting utility poles, which includes a support band having a pair of bands that symmetrically wrap around the utility pole and are connected to the pole, and a pair of bands made of a hard and soft mixed material that symmetrically wrap around the utility pole on the outside of the support band.

In addition, another prior art, Korean Utility Model Publication No. 20-2009-0007822, has previously disclosed a safety guard made of multiple protective units that are connected to each other with a cuttable region in between, and that include a buffer section, a cover section that encases the buffer section, and a reflector section that is bonded to one side of the cover section.

However, while the above-mentioned conventional technology aims to reduce the risk of collisions by installing it on structures that include utility poles, it has many problems, such as the following:

First, the cover adheres tightly to the utility pole, and moisture remains inside due to the water film phenomenon. This causes corrosion of the concrete utility pole and the iron core as shown in Figure 8a, weakening the utility pole and causing it to collapse, which can lead to a serious safety issue.

Secondly, installing the bands to secure the cover required a lot of time and effort, and as the band connections protruded in a knot shape, as shown in Figure 8b, the ends were often exposed to the outside in a sharp manner, causing frequent injuries to pedestrians.

Thirdly, existing safety guards have identification bands that are painted on. In this case, when exposed to the natural environment over a long period of time, including sunlight, rain, and temperature differences, the exterior, including the luminous display and reflective band, easily discolors and corrodes, as shown in Figure 8c, resulting in high maintenance costs. In municipalities with limited budgets, they are unable to replace them immediately, and there are various other problems, such as damage to the surrounding scenery.

Korean Patent Publication No. 10-2012-0033865 Korean Utility Model Publication No. 20-2009-0007822

The present invention is a new technology that aims to solve the problems of the conventional technology described above. It aims to provide a safety guard for preventing corrosion of utility poles that can maximize the recycling ratio of waste plastics, thereby reducing costs and being environmentally friendly, and that can prevent corrosion and breakage of utility poles due to moisture by forming a non-contact ventilation flow path between the safety guard and the utility pole.

Another objective of the present invention is to provide a safety guard for preventing corrosion of utility poles, in which the identification band is formed to a specified thickness by a double extrusion method using colored plastic to prevent discoloration, and when the protective band is installed on the utility pole, the fastening band can be installed without knots by engaging and fastening the hook blade and hook hole.

As a specific means for solving the above-mentioned problems of the invention, the present invention provides a safety guard for preventing corrosion of utility poles, which includes a base plate portion 10 formed on the inner surface in the shape of a sine wave curved surface 12 with inward and outward curved portions 12a, 12b alternately repeated, an identification band portion 20 formed alternately and repeatedly in different colors on the outer surface of the base plate portion 10, a side plate portion 30 formed on both ends of the base plate portion 10 with hook holes 32 formed therein, and a fastening band 40 provided with a plurality of hook blades 42 to be inserted and fastened into the hook holes 32 of the side plate portion 30, and the base plate portion 10 is characterized in that the outward curved portion 12b is separated from the outer surface of the utility pole 1 while the inward curved portion 12a is locally grounded to the outer surface of the utility pole to form a non-contact ventilation flow path 12c.

The identification band 20 is formed by extruding colored plastic so that it overlaps the surface of the base plate 10. The melting points of the recycled plastic that forms the base plate 10 and the colored plastic that forms the identification band 20 are different, and the base plate 10 is extruded into a predetermined cross-sectional shape by a main extruder, while the identification band 20 is extruded into a thickness thinner than that of the base plate 10 by an auxiliary extruder.

The joint surface between the base plate portion 10 and the identification band portion 20 is distributed with a large number of particles 50 that expand or explode when heated to a predetermined temperature or higher, and the particles 50 are heated and expanded or exploded during the extrusion molding process, so that the surfaces of the base plate portion 10 and the identification band portion 20 are physically bonded.

Furthermore, an inner uneven line 14 is formed on the surface of the base plate portion 10, an identification band portion 20 having a uniform thickness is formed on the surface of the inner uneven line 14, and an outer uneven line 24 having the same pattern as the inner uneven line 14 is formed on the identification band portion 20.

Furthermore, the side plate portion 30 has a concave arch-shaped guide curved surface 34 formed on the inner peripheral surface, and the guide curved surface 34 guides the fastening band 40 that is pulled in through the hook hole 32 so that it is bent and transported toward the utility pole 1.

Furthermore, the tension of the fastening band 40 is adjusted by a joint tool 46, which is characterized by having a joint plate 46a supported on the outer circumferential surface of the fastening band 40, a pair of fork blades 46b whose one end is connected to the joint plate 46a and whose other end extends to the inner circumferential surface of the fastening band 40 and is engaged and tied to the hook blade 42, and a handle 46c connected to the joint plate 46a.

Furthermore, the fastening band 40 is formed in two parts, one end of which is inserted into the hook hole 32 of the side plate part 30, and the other end of which is fastened by a clamp 45 while forming an overlapping part 44, and the overlapping part 44 is characterized in that a locking protrusion 44a is formed on the corresponding surfaces and is arranged to engage with the embossed structure and be locked and fastened.

As a specific means for solving the above problems, the present invention not only maximizes the recycling rate of waste plastics, thereby reducing costs, but is also environmentally friendly.

In addition, a non-contact ventilation passage can be formed between the safety guard and the utility pole to prevent accidents such as corrosion or breakage of the utility pole due to moisture.

In addition, the identification band is formed to a specified thickness by double extrusion molding using colored plastic, so there is no loss of visibility due to wear, and it has excellent weather resistance, so it can maintain vivid visibility for a long period of time.

In particular, the fastening band is installed without knots by engaging and fastening the hook blade and hook hole, making it difficult for anyone other than those involved to untie the fastening, and the expected effects are great, such as preventing safety accidents such as pedestrians being injured by protruding knots while moving around.

The technical terms used in this specification are terms selected with consideration of the functions in the embodiments, and the meaning of the terms may vary depending on the specific embodiment of the invention. Furthermore, throughout the specification, when a part is said to be "connected (connected, in contact, bonded)" to another part, this includes not only "directly connected (connected, in contact, bonded)" but also "indirectly connected" with another member between them. Note that the terms "upper side," "lower side," and "front-rear direction" used in the following description are defined based on the drawings, and these terms do not limit the shape and position of each component.

The present invention will be described in more detail below based on the specific embodiments shown in the attached drawings. Figure 1 shows a preferred embodiment of the safety guard for preventing corrosion of utility poles provided in the present invention, and Figure 2 is a plan view showing the state in which the safety guard for preventing corrosion of utility poles is installed on a utility pole.

The present invention relates to a safety guard for preventing corrosion of utility poles, which can maximize the recycling ratio of waste plastics to reduce costs and be environmentally friendly, and which forms a non-contact ventilation flow path between the safety guard and the utility pole to prevent corrosion and breakage of the utility pole due to moisture. The main components are roughly a base plate portion 10, an identification band portion 20, a side plate portion 30, and a fastening band 40.

First, the base plate portion 10 according to the present invention is extruded to have a predetermined cross-sectional shape, and is then cut to a predetermined length in consideration of the length of the utility pole, the installation location, and the environment.

The inner peripheral surface of the base plate portion 10 is formed into a sine wave curved surface 12 in which inward and outward curved portions 12a, 12b are alternately repeated. Therefore, when the base plate portion 10 is installed to wrap around the utility pole 1, the sine wave curved surface 12 forms a non-contact ventilation flow path 12c, as shown in the enlarged view of FIG. 2.

At this time, in order to ensure smooth drainage, the non-contact air flow passage 12c forms a sine wave curved surface 12 with a height of 0.2 mm or more on the horizontal cross section.

With the above-mentioned structure, the base plate portion 10 forms a non-contact ventilation flow path 12c in which the outward curved portion 12b and the outer peripheral surface of the utility pole 1 are separated by a distance of 0.2 mm or more when the inward curved portion 12a is locally grounded to the outer peripheral surface of the utility pole. As a result, in rainy weather, rainwater is quickly discharged into the non-contact ventilation flow path 12c and air is easily circulated, so that the base plate portion 10 and the utility pole 1 are always kept dry, preventing accidents such as corrosion and breakage of the utility pole 1 due to moisture.

The base plate portion 10 is formed by extruding recycled plastic, and the identification band portion 20 is formed by extruding colored plastic so that it overlaps the surface of the base plate portion 10.

The identification band portion 20 of the present invention is formed on the surface of the base plate portion 10 in alternating, repeated patterns of different colors to make it easier for the driver to identify.

As an example, the identification band 20 is formed with alternating yellow and black regions as shown in FIG. 1, with the yellow regions narrower than the black regions (e.g., 70-80 mm for the black regions and 40-60 mm for the yellow regions), a danger warning message is screen-printed in the central yellow region, and reflective paper is attached to the adjacent yellow regions to enhance the driver's identification during daytime and nighttime driving.

Meanwhile, the base plate portion 10 is extruded into a predetermined cross-sectional shape by the main extruder, and the identification band portion 20 is extruded into a thickness thinner than the base plate portion 10 by the auxiliary extruder, so that the safety guard is manufactured by a multiple extrusion method.

In this case, the melting points of the recycled plastic forming the base plate portion 10 and the colored plastic forming the identification band portion 20 are different from each other, and even within the colored plastic, the melting points of the plastic in the yellow region and the plastic in the black region are also different from each other. For example, the melting point of the colored plastic may be set even lower.

If the melting points of the resins are the same, the boundary between the yellow and black regions may be unclear, or the thickness of the identification band portion 20 laminated on the base plate portion 10 may not be uniform.

Figure 3 is a diagram showing the bonding state between the base plate part and the identification band part of a safety guard for preventing corrosion of utility poles according to one embodiment of the present invention, in which a large number of particles 50 that expand or explode when exposed to heat above a predetermined temperature are distributed on the bonding surface between the base plate part 10 and the identification band part 20.

The particles 50 are heated and exploded during the extrusion molding of the base plate portion 10 and the identification band portion 20, so that the surfaces of the base plate portion 10 and the identification band portion 20 are physically bonded together, thereby firmly maintaining the integrity of the double extrusion between the different materials.

In this way, the identification band 20 is double extrusion molded on the base plate 10, and is formed to have a predetermined thickness (0.2 to 0.4 mm) from colored plastic (PVC), so there is no loss of visibility due to wear. In addition, even if it is exposed to the external natural environment, including sunlight, snow, rain, and temperature differences, it does not discolor or lose its color, so it has excellent weather resistance, and therefore has the advantage of always ensuring a clear field of vision and ensuring safe driving. In addition, since the base plate 10 is formed from recycled plastic (waste plastic), it has the environmentally friendly effect of reducing manufacturing costs by recycling nature, as well as contributing to carbon neutral policies by recycling waste materials.

Figure 4 is an enlarged diagram of the identification band of the safety guard for preventing corrosion of utility poles, where Figure 4a is a diagram showing the black area of the identification band 20, and Figure 4b is a diagram showing the yellow area of the identification band 20.

An inner uneven line 14 is formed on the surface of the base plate portion 10, and an identification band portion 20 is formed on the surface of the inner uneven line 14. At this time, the identification band portion 20 is formed to a uniform thickness, so that an outer uneven line 24 is formed on the surface of the identification band portion 20.

That is, in the process of extruding the base plate portion 10, an inner uneven line 14 is formed on the surface by the extruder die, and then, as the identification band portion 20 is extruded onto the surface of the inner uneven line 14, an outer uneven line 24 having the same shape and pattern as the inner uneven line 14 is formed.

When the base plate section 10 is wrapped around the utility pole 1 and installed using the inner and outer uneven lines 14, 24 configured in this way, the flexibility to deform into a circular shape is improved, and there is an advantage in that the area of the surface that can be affixed to illegally attached items such as flyers is reduced, making them easier to remove.

Figure 5 is a diagram showing the fastening structure of a fastening band of a safety guard for preventing corrosion of utility poles according to one embodiment of the present invention.

The side plate portion 30 according to the present invention is formed on both ends of the base plate portion 10, and a hook hole 32 is formed on each end. The identification band portion 20 having a predetermined color can be formed on the outer peripheral surface of the side plate portion 30 by a double injection method.

As shown in FIG. 5, the side plate portion 30 has a concave arch-shaped guide curved surface 34 formed on the inner peripheral surface in a planar cross-sectional view, and the outer surface also has a curved shape as a whole so that the amount of protrusion to the outside is minimized. The guide curved surface 34 guides the end of the fastening band 40 that is pulled in through the hook hole 32 so that it is bent and transported toward the utility pole 1.

As a result, the fastening band 40 rides on the guide curved surface 34 of the side plate portion 30 and is guided so that it can be inserted quickly without getting caught while bending inward, thereby enabling the fastening operation to be performed effectively, and the fastening band 40 is tightly attached to the inside of the hook hole 32, making it possible to firmly maintain the binding force between the hook blade 42 and the hook hole 32.

The fastening band 40 according to the present invention is made of a synthetic resin material that is flexible and elastic, and has multiple hook blades 42 protruding obliquely from one side so that they can be inserted into the hook holes 32 of the side plate portion 30 and fastened.

As shown in FIG. 1, the hook blades 42 are formed in opposite directions in the regions on both sides of the fastening band 40. That is, the hook blades 42 arranged at both ends of the fastening band 40 are formed so that they form acute angles with the fastening band, and are arranged so that, with one hook blade 42 fastened to the hook hole 32 of the side plate portion 30, the other fastening band 40 is inserted into the hook hole 32 of the opposite side plate portion 30 for fastening.

In this way, the safety guard can be firmly attached to the post without knots by fastening the fastening band 40 with the hook blade 42 and the hook hole 32, and since the fastening part is not exposed to the outside, the fastening cannot be released by anyone other than the relevant personnel.

Another benefit is that it can prevent safety accidents, such as pedestrians being injured while moving around due to existing metal knots protruding outwards and looking unsightly.

Figure 6 is a diagram showing a safety guard joint tool, which is used to easily adjust the tension of the fastening band 40 so that the safety guard can be securely fastened to the utility pole.

Specifically, the joint tool 46 is configured to include a joint plate 46a supported on the outer circumferential surface of the fastening band 40, a pair of fork blades 46b, one end of which is connected to the joint plate 46a and the other end of which extends to the inner circumferential surface of the fastening band 40 and is engaged and fastened to the hook blade 42, and a handle 46c connected to the joint plate 46a.

In order to increase the pulling force of the fastening band 40 during use, the handle 46c is formed so that it crosses the joint plate 46a rather than being aligned in a straight line.

When examining how it is used, the fastening band 40 is inserted between the joint plate 46a and the fork blade 46b, the hook blade 42 is fitted to the fork blade 46b, and the handle 46c is pulled outward in the direction of the arrow in the figure. This allows the fastening band 40 to be easily pulled and inserted into the hook hole 32 by the principle of leverage, and therefore the safety guard can be firmly fastened to the utility pole without loosening.

Figure 7 is a diagram showing an embodiment of a fastening band clamp in the safety guard for preventing corrosion of utility poles of the present invention.

In this case, the fastening band 40 is formed in two parts, one end of which is inserted into the hook hole 32 of the side plate portion 30, and the other end is fastened by the clamp 45 while forming the overlapping portion 44.

The overlapping portions 44 have locking protrusions 44a formed on the corresponding surfaces thereof, which are designed to engage with the embossed structure and lock together.

At this time, the clamp 45 has a hole that can accommodate all of the overlapping parts 44, and a tightening bolt that is screwed on to one side is provided, so that when the tightening bolt is tightened to bring the overlapping parts 44 into close contact with each other while the overlapping parts 44 are fitted into the clamp 45, the locking protrusions 44a engage to maintain a strong bond.

As mentioned above, the most preferred embodiment of the present invention has been described in the detailed description of the present invention, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above embodiment, but should be extended to the technology of the claims described below and equivalent technical means.

The safety guard provided in the present invention forms a non-contact ventilation passage between the safety guard and the utility pole, preventing accidents such as corrosion or breakage of the utility pole due to moisture, and provides excellent weather resistance and visibility, making it highly applicable in industry.
